Description

FIELD OF THE INVENTION

The present invention relates to the field of mechanics and, in particular, to a striking method of excavation using rolling friction or suspension friction in the field of mining and to a wear-resistant impact cutting machine using this method.

BACKGROUND OF THE INVENTION

Driving machines and coal combines are mainly used for excavation in the construction of railways, bridges and culverts on roads and tunnels and for the development of ore materials with mechanical excavation. Most of the mining machines that are widely used at present are cutting-type tunneling machines with drilling and grinding, and cutting-type tunneling machines with grinding, and cutting-type mining machines with drilling and grinding, the principle of which is drilling and cutting or grinding and cutting with rolling of a coal seam or rock formation by means of teeth located on the outer surface in front of the cutting head. Since a relatively large damaging torque is generated during drilling and grinding, rolling, grinding and cutting with the cutting head, a relatively large torsional force will be applied to the rotating shaft, causing severe damage to the rotating shaft and shortening the life of the equipment. The crushing efficiency of the drilling and grinding or grinding and cutting method is relatively high with extremely high energy consumption and low production productivity and large caliber, especially if crushing during sinking and excavation of ore material is carried out under pressure stress. In addition, a large amount of dust will be created during the extraction process, resulting in an environment unfavorable for production and potential risks. To eliminate various disadvantages of the method of excavation with crushing and grinding or grinding and cutting in the field of mining, mining shock machines with reciprocating motion appeared.

In order to increase production efficiency, the cutting head of an existing mining shock machine with reciprocating motion is made as large as possible. When the material is beaten and collapsed, since the cutting head of the mining machine is heavy in weight and large in volume, the cutting head seriously damages the directing blow of the mechanism, thus leading to damage to the drive system and the machine body, and a large amount of repair and maintenance work on the entire machine and short service life. On the other hand, if the cutting head is narrow and small, production performance will be significantly reduced. Therefore, there is an urgent need for an energy-saving and environmentally friendly mining impact machine with high performance and capable of preventing the cutting head from damaging the impact guiding mechanism with low wear of the impact guiding mechanism and small damage caused by the reaction force of the impact on the drive system and the machine body.

In the description of the invention to patent No. 201010238402.7 a crushing mechanism for a coal mining device is disclosed. The equipment consists of a main body, a power component, a working component and a connecting lever, etc. The power component brings the working component, forcing it to make a reciprocating motion and make linear hits to collapse the coal. The power component is a hydraulic cylinder. Between the piston in the hydraulic cylinder and the cylinder body, sliding friction occurs with high friction resistance, which causes severe wear on the sealing plug and increases the clearance between the piston and the cylinder body with increased leakage, while increasing energy consumption and degrading equipment performance. In this invention, a hydraulic cylinder is used to drive a working component for delivering impacts at a low speed and a low frequency, thereby not realizing the effect of high-frequency impacts of a mechanical transmission mechanism, for example a crank mechanism. The working component is mounted on the end of the hydraulic cylinder. When the hydraulic cylinder drives the working component, forcing it to extend or retract in the axial direction of the hydraulic cylinder, additional problems of the working component arise, including swaying and oscillation, etc., reflected in the impact action. Since the stem of the hydraulic cylinder is not equipped with an auxiliary guiding device, the working component seriously damages the hydraulic cylinder with the powerful force of the shock reaction created during excavation. Thus, the sliding friction force is concentrated on the hydraulic cylinder, causing partial wear, which ultimately leads to severe damage to the hydraulic cylinder and adversely affects the normal operation of the equipment.

The multi-crank shaft is rational in design and manufactured in a small volume to greatly facilitate the shock part with reciprocating motion and increase the flexibility of adjusting the shock part with reciprocating motion.

A multi-crank shaft consists of several eccentric shafts. Each eccentric shaft drives one power impact element. The other end of the force impact element is provided with one or more impact heads, which significantly increases the production rate.

The eccentric shafts of the multi-cranked shaft are located symmetrically in the radial direction of the concentric power section of the shaft to create an angular difference. Power shock elements driven by eccentric shafts can strike a coal seam or rock formation at different time periods. The reaction force created by the impact of a power shock element can be converted into the energy of the next power shock element from the same side. At the same time, the reaction force created by a single impact on a powerful coal seam or rock formation is decomposed in such a way that the impact drive device is tensioned uniformly to absorb and stabilize the machine body.

As shown in FIG. 58 (wear-resistant mining impact machine), the impact head 6 comprises impact teeth for the material of the outer layer 6.1 and impact teeth for the material of the inner layer 6.2. Impact teeth for the material of the inner layer 6.2 are provided so as to collapse the material of the inner layer of the coal face or rock formation to be excavated. Impact teeth for the material of the outer layer 6.1 are made of such a shape or are arranged so that material collapsed by the impact teeth for the material of the inner layer 6.2 can flow out from the gaps between the impact teeth for the material of the outer layer 6.1. Impact teeth for the material of the outer layer 6.1 and the impact teeth for the material of the inner layer 6.2 are arranged in parallel to form a multilayer impact head 6. The multilayer impact head 6 increases the width of the recess and increases production productivity.

The impact mechanism for several layers is used to extract the object to be taken out, layer by layer, thereby reducing the impact resistance caused by hitting a powerful object to be taken out, not layer by layer, reducing damage caused by the large force of the impact reaction of the impact part with reciprocating motion and machine body, reducing energy consumption in the process of power transmission and increasing labor productivity.

Impact teeth of the impact head are several rows of impact teeth for impacts on a coal seam or rock formation in several stages with the destruction of a collapsed coal block or rock block to produce grains suitable for conveyor transportation in one step, which avoids the problem of difficulty transporting from - for excessively large pieces in the mining process.

After the coal face or rock formation is subjected to impact in several stages, the material collapses due to the use of two opposite free surfaces of the stepped coal face or rock formation when the percussion teeth 6.3.1 of each layer excavate again, which significantly reduces the impact resistance, avoids excessively large pieces of material collapsed by the impact head 6, reduces energy consumption and increases the effectiveness of the impact.
