Technical field of the invention
[0001] The present invention belongs to the mechanical field, and is especially applicable to a rolling friction or suspension friction impact mining method in the mining field and a wear-resistant impact mining machine using said method.
Background of the invention
[0002] Tunneling machines and coal mining machines are mainly applied to excavation of railways, bridges and culverts of roads and tunnels and mechanical mining of ore materials. Most mining machines broadly applied at present are drilling and milling cutting-type tunneling machines and rolling milling cutting-type mining machines and the working principle is to drill and cut or mill and cut in a rolling manner a coalbed or a rockbed through picks arranged on the outer surface at a front part of a cutting head. Since a relatively large rotating damage force is generated by the cutting head during drilling and milling or rolling milling and cutting, a relatively large twisting force will be generated to a rotating shaft, thus causing heavy damage to the rotating shaft and shortening the equipment service life. The crushing efficiency of a drilling milling or milling cutting mining method is relatively high with extremely high energy consumption, and low production efficiency and lumpiness especially when tunneling crushing and ore material mining are performed at a pressure stress. During the mining process, a large amount of dust will be further generated, which results in a poor mining environment and potential risks. In order to overcome various disadvantages of the drilling milling or milling cutting mining method, reciprocating impact mining machines have emerged in the mining field.
[0003] In order to improve the mining efficiency, a cutting head of an existing reciprocating impact mining machine is made as large as possible. When a material is impacted and fallen, since the cutting head of the mining machine is heavy in weight and large in volume, a head handle of the cutting head is seriously damaged from an impact guiding mechanism, thus leading to damage on a drive system and a machine body, massive maintenance of the whole machine and a short service life. However, if the cutting head is narrow and small, the production efficiency will be largely reduced. Therefore, it is in urgent need of an energy-saving and environment-friendly impact mining machine which is high in production efficiency and capable of preventing a cutting head from damaging an impact guiding mechanism with little wear to the impact guiding mechanism, and little damage caused by an impact reactive force on a drive system and a machine body.
[0004] Invention Patent Numbered 201010238402.7 discloses a crushing mechanism for a coal mining device. The equipment is composed of a main body, a power component, a working component and a connecting arm etc. The power component drives the working component to reciprocate and impact linearly to perform coal falling. The power component applies a hydraulic cylinder. There is sliding friction between a piston in the hydraulic cylinder and the cylinder body with large friction resistance, thus causing serious wear to a sealing plug and increasing a gap between the piston and the cylinder body to increasing leakage while increasing energy consumption and affecting the operational performance of the equipment. In the present invention, the hydraulic cylinder is applied to driving the working component to impact at a low speed with a low impact frequency, thus failing to realize a high frequency impact effect of a mechanical transmission mechanism, e.g. a crank mechanism. The working component is installed at an end of the hydraulic cylinder. When the hydraulic cylinder drives the working component to extend out or retract along an axial direction of the hydraulic cylinder, problems including swinging and oscillation etc. of the working component are further caused to affect the impact effect. Since a hydraulic cylinder rod is not provided with an auxiliary guiding device, the working component is seriously damaged from the hydraulic cylinder by a powerful impact reactive force generated during mining. Thus, a sliding frictional force is focused on the hydraulic cylinder to cause partial wear, which results in heavy damage on the hydraulic cylinder and affects normal operation of the equipment.
