[0002] The reciprocating punching teeth of the existing mining machines, rock drills and breakers are all provided with a tooth seat and a tooth head for reciprocating impact. Therefore, the tooth seats are all single-layer tooth seats. The area is small and the work efficiency is low, especially when the reciprocating punching teeth swing left and right to impact the material, the slope of the single tooth seat and the top tooth of the single tooth head prevents the reciprocating punching teeth from impacting the material on the side wall, causing the material on the side wall to collide with the reciprocating punching head Sliding friction between the side wall and the side wall of the tooth seat, severe wear and tear on the side of the reciprocating tooth seat and the tooth head, and the resulting strong resistance frequently causes the motor or motor to be overloaded, and in severe cases, the motor or motor is quickly damaged. The original reciprocating punching teeth of the reciprocating impact shearer are equipped with a tooth head for a tooth seat. When it is necessary to widen the one-time mining area, multiple single-head tooth seats are set on the wide shovel tooth plate. The seats are densely arranged on the same plane of a shovel tooth plate, so that the mined material cannot flow out of the gap between the tooth seats, because the materials sandwiched between the tooth seats and the tooth seats are filled, and the materials impacted by the tooth head cannot be smoothly exported, resulting in the excavation The material is crushed, and in severe cases, the impact teeth are filled with materials and cannot work continuously. In order to prevent the reciprocating punching teeth on the original shovel tooth plate from being unable to work continuously due to materials being trapped, a single tooth seat for each reciprocating punching tooth Heightening, due to the heightening of a single gear seat, the force arm of the reciprocating punching gear, guiding mechanism, and power mechanism is increased, resulting in a short service life of the reciprocating punching gear, guiding mechanism, and power mechanism. When the height difference reciprocating impact teeth are arranged on the same plane, the tooth seat of the reciprocating punching tooth with a high tooth top is made thin and high, and the thin and high tooth seat is set perpendicular to the shovel tooth plate. Protrude the tooth shank from the bottom of the tooth seat, because the original reciprocating punching tooth shank cannot extend out of the bottom of the tooth seat, and the tooth head can only be removed from the front part of the reciprocating punching tooth, but not from the rear end of the reciprocating punching tooth Withstand the reciprocating punching tooth handle and push the tooth head down with the backward pulling force of the reciprocating impact stroke, which makes it difficult to disassemble the tooth head, and even causes the tooth head and the tooth seat to be too tight or locked due to the reciprocating impact. , which greatly reduces the excavation efficiency and the block rate of the mined materials. Due to the use of the shovel tooth plate with the same width and height as the front section of the excavation impact integrated block seal guide lock box, the gap between the shovel tooth plate and the integrated block seal guide lock box is caused. The clamped material cannot be discharged, and the material forms a pad between them. When the pad is reciprocating, the shovel tooth plate cannot be retracted, resulting in losses such as continuous reciprocating impact and shutdown maintenance. Coal mining machines and tunneling machines often use screw nuts to fix the reciprocating punching teeth and power guides together. Under the action of strong reciprocating impact reaction force, the nuts will fall off quickly due to vibration or the thread will be deformed by the impact. The reciprocating punching tooth cannot be replaced due to the deformation and seizure. Because the area of ​​the shoveling tooth plate is too large, in order to reduce the weight, the shoveling tooth plate is made thinner. Because of the thin shoveling tooth plate, the shoveling tooth plate is deformed under the strong reciprocating impact reaction force, and the Because the shovel tooth plate blocks a large area of ​​the space where the water spraying and cooling device spray water to the impact teeth, the reciprocating impact teeth are quickly overheated and damaged. The reciprocating impact teeth spray water and cool down, that is, make water channels and install water nozzles on the large reciprocating shovel-tooth plate. Due to the reciprocating impact of the shovel-tooth plate, the accumulated materials will quickly block the water nozzle, making water spraying and cooling The system failed. The strength of the shovel-tooth slab structure was reduced due to the water channels installed in multiple places in the horizontal direction of the shovel-tooth slab, and the processing and manufacturing were complicated. The impact shearer and the roadheader cannot be used in the actual mining production site. In order to solve the above problems, the present invention proposes the method of implementing interlocking guiding and sealing the socket of the gear seat to set the main and side reciprocating teeth and the mining machine socket to set the main and side teeth.
