Abstract
The utility model discloses a novel mineral thread chip removal type coal cutting pick. The novel mineral thread chip removal type coal cutting pick comprises a cutting pick handle and a cutting pick head, wherein a wear resisting head is arranged at the front end of the cutting pick head, the cutting pick handle is provided with a thread lubrication groove, and a chip groove is formed at a junction of the cutting pick handle and the cutting pick head. The novel mineral thread chip removal type coal cutting pick can be used for solving the problem that the coal cutting pick has low wear resistance and is inconvenient for chip removal; the novel mineral thread chip removal type coal cutting pick is simple in design, reasonable in structure and convenient for chip removal by arranging the thread wear resisting head at the front end of the cutting pick head and forming the thread lubrication groove in the cutting prick handle and the chip removal groove at the junction of the cutting pick handle and the cutting pick head; and the service life of the whole novel mineral thread chip removal type coal cutting pick is prolonged.
Description
Technical field
The utility model relates to mining part of appliance technical field, specifically belongs to new mine product screw thread chip removal type coal cutting pick.
Background technology
High-performance coal cutting pick is the critical component on large-scale digger, the one, and because the cone segments end wall of cutting pick head cutting pick handle is around planar annular, the planar annular of this cone segments end wall, impacting in pick, also be the position of stressed maximum, so, be easy to be worn and damage.In process of production, because coal cutting pick is direct face.Broken coal stone spatters very soon into the gap between coal cutting pick and coal digging machine department of assembly, very easily results in blockage and makes this product not rotate generation eccentric wear, and consequence is that alloy head comes off and this product fractures.Take a lot of work, time-consuming, production efficiency very low cost increases, waste resource, and enterprises' loss is very large.
Utility model content
The purpose of this utility model has been to provide new mine product screw thread chip removal type coal cutting pick, solved the problem of the not wear-resisting inconvenience excretion of coal cutting pick, simplicity of design, rational in infrastructure, by being provided with screw thread wear-resisting head at cutting pick head front end, on cutting pick handle, there is screw thread lubrication groove, cutting pick handle and cutting pick head junction are provided with chip area, excretion is convenient, improves Whole Equipment application life.
The technical solution adopted in the utility model is as follows:
New mine product screw thread chip removal type coal cutting pick, comprises cutting pick handle and cutting pick head, and described cutting pick head front end is provided with wear-resisting head, has screw thread lubrication groove on described cutting pick handle, and cutting pick handle and cutting pick head junction are provided with chip area.
Described wear-resisting head is threaded-structure.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model, by being provided with screw thread wear-resisting head at cutting pick head front end, has screw thread lubrication groove on cutting pick handle, cutting pick handle and cutting pick head junction are provided with chip area, and excretion is convenient, improves Whole Equipment application life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, new mine product screw thread chip removal type coal cutting pick, comprises cutting pick handle 1 and cutting pick head 2, and cutting pick head 2 front ends are provided with wear-resisting head 201, and wear-resisting head 201 is threaded-structure.Improve cutting pick head 2 abrasion resistancies, increase the service life, on described cutting pick handle 1, have screw thread lubrication groove 101, cutting pick handle 1 is provided with chip area 3 with cutting pick head 2 junctions, and excretion is convenient, improves Whole Equipment application life.
