Detailed embodiments

[0028] The application will be described in further detail below with reference to accompanying drawings 1-6.

[0029] A method for ecological restorage of mine vegetation with simulate loam includes the following steps:

Step 1: fixing a hanging net on a mine surface, to facilitate the improvement of the adhesive force of the simulate loam on the mine surface when the spray seeding technology is subsequently adopted to spray seed simulate loam on the mine surface, so that the simulate loam is less likely to be lost under the erosion by rainfall after spray seeding.

Step 2: spray seeding a first layer of simulate loam on the mine surface to form a basic layer of simulate loam substrate for simulating a leaching horizon. Further, the simulate loam is adopted, so as to store more nutrients and to improve the survival rate of plants after planting.

Step 3: spray seeding a second layer of simulate loam on a surface of the first layer of simulate loam, to form a surface layer of simulate loam substrate for simulating a humus horizon or a weathered layer, such that dust, leaves and the like can be prevented from flying away with the wind and can be retained on the second layer of simulate loam when the wind blows with dust, leaves and the like, so as to increase the thickness of the soil layer and improve the soil fertility, so that plants can get more nutrients after sowing, which accelerates the growth of plants and further improves the survival rate of plants.

Step 4: before sowing, proportioning and soaking the plant seeds according to the results of field investigation. The soaking can improve the germination efficiency of plant seeds and accelerate the growth of plants. Further, soaking can reduce diseases and insect pests in the plant seeds and improve the survival rate of plants.

[0030] After the completion of the soaking, sowing seeds on the second layer of simulate loam. In the case that shrubs are planted on the second layer of simulate loam, the shrubs grow faster and take root faster, such that the surface soil layer can be quickly anchored and fixed, which reduces soil erosion and improves the survival rate of other plants. In the case that arbors are planted on the second layer of simulate loam, there should be gaps between adjacent arbors when planting arbors, which is convenient for arbors to take root and reduce the competition for nutrients between arbors. The arbors are deeply rooted, which can better anchor and fix the soil layer, so as to further reduce soil and water erosion, and improve the survival rate of plants.

[0031] The growth speed of arbors is different from that of shrubs. Shrubs grow faster, but they are easy to die in winter. The dead shrubs form food for the slow-growing arbors, so that the arbors can get sufficient nutrients when growing up, which accelerates the growth efficiency of the arbors and improves the survival rate of arbors. After the arbors grow up, the soil layer is fixed by the arbors, and nutrients are not easily lost. Shrubs can easily sprout and grow in spring. A new cycle is started.

[0032] Referring to Fig. 1 and Fig. 2, the embodiment of the present application further discloses a proportioning equipment. The proportioning equipment includes a plurality of soaking barrels 1 and a stirring barrel 2. The side wall of each soaking barrel 1 is penetrated by a discharge hole 8. The discharge hole 8 is defined at the bottom of the soaking barrel 1. There is a conveying pipe 3 between each soaking barrel 1 and the mixing barrel 2. The first end of the conveying pipe 3 is fixed on the outer wall of the soaking barrel 1 and is in communication with the discharge hole 8. The second end of the conveying pipe is in communication with the stirring barrel 2. After the plant seeds are soaked in the soaking barrel 1, they are transported to the stirring barrel 2 through the conveying pipe 3. The plant seeds conveyed from different soaking barrels 1 are stirred and mixed in the stirring barrel 2 to facilitate sowing.

[0033] Referring to Fig. 2 and Fig. 3, an adjustment assembly 4 is provided on the outer wall of the soaking barrel 1. The adjustment assembly 4 includes an adjustment ring 41 and a transmission wheel 42. The outer wall of the soaking barrel 1 is configured with an annular chute 10. The adjustment ring 41 is arranged in the chute 10. The adjustment ring 41 is penetrated by a throughhole 9. The top surface of the adjustment ring 41 is integrally formed with transmission teeth. The transmission wheel 42 is arranged in the chute 10. The transmission wheel 42 is a gear. The transmission wheel 42 is meshed with the transmission teeth. A first driving motor 43 is fixed on the outer wall of the soaking barrel 1, the output shaft of the first driving motor 43 is coaxially and fixedly connected to the transmission wheel 42. The first driving motor 43 drives the transmission wheel 42 to rotate, which in turn drives the adjustment ring 41 to rotate. During the rotation of the adjustment ring 41, the throughhole 9 and the discharge hole 8 are gradually communicated. By controlling the communication area between the throughhole 9 and the discharge hole 8, the discharge speed of seeds in the soaking barrel 1 is controlled. By controlling the discharge speed of seeds in different soaking barrels 1, the proportioning of plant seeds is facilitated.

[0034] Referring to Fig. 2 and Fig. 3, the outer wall of the soaking barrel 1 is provided with an opening and closing assembly 5. The opening and closing assembly 5 is arranged in the conveying pipe 3. The opening and closing assembly 5 includes a lifting plate 51, a guide rod 52 and a lifting screw rod 53. The guide rod 52 is vertically fixed on the outer wall of the soaking barrel 1. The lifting screw rod 53 is vertically fixed on the outer wall of the soaking barrel 1. The first end of the lifting plate 51 is screwed to the lifting screw rod 53. The second end of the lifting plate is penetrated by a socket for the guide rod 52. A second driving motor 54 is fixed on the outer wall of the soaking barrel 1. The output shaft of the second driving motor 54 is coaxially and fixedly connected to the lifting screw rod 53. The second driving motor 54 drives the lifting screw rod 53 to rotate and in turn drives the lifting plate 51 to lift. During the gradual communication between the adjustment ring 41 and the discharge hole 8, the initial conveying speed of the seeds in a plurality of soaking barrels 1 is the same. When the conveying speed of the seeds in the soaking barrels 1 no longer changes, the conveying speed of the seeds in the plurality of soaking barrels 1 are no longer the same, which leads to errors in the proportion of the plant seeds at the beginning. After the lifting plate 51 is attached to the outer wall of the adjustment ring 41 and the adjustment ring 41 is adjusted, the lifting plate 51 rises, to connect the throughhole 9 with the conveying pipe 3, so that the initial conveying speeds of the plant seeds are different from each other, thereby improving the accuracy of proportion of plant seeds.

[0035] Referring to Fig. 2 and Fig. 4, a pressure regulating cavity 29 is configured in the soaking barrel 1. An installation cavity 30 in communication with the pressure regulating cavity 29 is configured in the soaking barrel 1. A first piston block 31 is arranged in the pressure regulating cavity 29. A second piston block 32 is arranged in the installation cavity 30. The side wall of the first piston block 31 is integrally formed with a driven block 34. The outer wall of the soaking barrel 1 is configured with a groove 36 in communication with the pressure regulating cavity 29. The driven block 34 is arranged in the groove 36 and protrudes from the groove 36. A transmission rod 35 is fixed on the bottom surface of the lifting plate 51. The bottom end of the transmission rod 35 is fixedly connected to the driven block 34. When the lifting plate 51 rises or sinks, it can drive the driven block 34 to rise or sink, thereby driving the first piston block 31 to slide in the pressure regulating cavity 29. When the first piston block 31 rises in the pressure regulating cavity 29, the air pressure in the pressure regulating cavity 29 increases, so that the air in the pressure regulating cavity 29 flows toward two installation cavities 30, therefore, the air pressure in the installation cavities 30 increases, so that the second piston block 32 slides upward. On the contrary, when the lifting plate 51 sinks, the pressure in the pressure regulating cavity 29 decreases, so that the second piston block 32 is driven to slide downward.

[0036] Referring to Fig. 2 and Fig. 4, the bottom surface of the adjustment ring 41 is provided with locking teeth 44. The inner wall of the chute 10 facing the locking teeth 44 is configured with an aperture 38. A slider 37 is arranged in the aperture 38. One end of slider 37 away from the adjustment ring 41 is fixedly connected to the second piston block 32. Limiting teeth 33 are integrally formed on the side of the slider 37 facing the adjustment ring 41. When the slider 37 is driven to rise by the second piston block 32, the limiting teeth 33 can be meshed with the locking teeth 44, thereby preventing the adjustment ring 41 from rotating and improving the stability of the adjustment ring 41 in the chute 10.

[0037] Referring to Fig. 2 and Fig. 4, when the discharge area of the discharge hole 8 is adjusted by the adjustment ring 41, the lifting plate 51 closes the discharge hole 8 at this time, in particular, the first piston block 31 is located at the bottom of the pressure regulating cavity 29, and the slider 37 is accommodated in the aperture 38. When the lifting plate 51 rises to open the discharge hole 8, the first piston block 31 rises with the lifting plate 51, so that the limiting teeth 33 on the slider 37 are gradually meshed with the locking teeth 44 on the adjustment ring 41, so as to prevent the adjustment ring 41 from rotating under the pressure of the plant seeds, thereby improving the stability of the adjustment ring 41. Referring to Fig. 2 and Fig. 3, the bottom of the soaking barrel 1 is configured with a discharge outlet. A filter 16 is fixed on the inner wall of the discharge outlet. A sealing plate 17 is articulated with the inner wall of the discharge outlet. The sealing plate 17 is arranged below the filter 16. An air cylinder 18 is articulated with the inner wall of the discharge outlet. The piston rod of the gas cylinder 18 is articulated with the end of the sealing plate 17 away from the hinge point where it is articulated with the soaking barrel 1. In the normal state, the piston rod of the air cylinder 18 extends, and the sealing plate 17 closes the discharge outlet, such that the seeds can be soaked in the soaking barrel 1. After the completion of the soaking, the piston rod of the air cylinder 18 is retracted, so that the liquid for soaking is discharged from the discharge outlet, and the filter 16 blocks the plant seeds in the soaking barrel 1.

[0038] Referring to Fig. 2 and Fig. 3, one end of the filter 16 close to the discharge hole 8 inclines downward, so that the plant seeds on the filter 16 tend to roll toward the discharge hole 8, which facilitates the transportation of the plant seeds in the soaking barrel 1 to the conveying pipe 3.

[0039] Referring to Fig. 2 and Fig. 3, a fixing plate 11 is fixed on the top surface of the soaking barrel 1. A third driving motor 14 is fixed on the fixing plate 11.

[0040] Referring to Fig. 2 and Fig. 3, after the completion of the soaking, the third driving motor 14 is started, to drive the connecting rod 12 and the stirring blade 13 to rotate, which facilitates lifting the plant seeds upward, so that the plant seeds surge in the soaking barrel 1. Plant seeds are floating around due to the water flow. Under the guidance of the guide ring 15, the plant seeds float toward the connecting rod 12 and the stirring blade 13, which facilitates the reciprocating stirring of the plant seeds. There is a significant difference in density between intact seeds and seeds with pests and diseases after soaking, in particular, the density of the intact seed is greater, while the density of the seed with pests and diseases is smaller. By stirring the seeds up and down, a large number of seeds with pests and diseases are accumulated at the top, such that the survival rate of plant seeds at the bottom and in the middle is improved, while plant seeds at the top can be selected as needed.
