Description

Wear-resistant reinforced coal mining cutting pick

Technical Field

The utility model relates to a coal mining equipment technical field, concretely relates to wear-resisting strenghthened type coal mining pick.

Background

The coal cutting pick is mainly applied to coal mining construction of a coal mine, and plays a role in breaking rocks and crushing coal in the coal mining construction process. When the cutting pick works, the head of the cutting pick directly contacts with a working surface, and the cutting pick is worn quickly due to the complex and severe working environment, and once the cutting pick is worn seriously, the cutting pick fails. At the same time the pick shank is mounted inside the block with little play. When the cutting pick works, the working part of the cutting pick is stressed, the rod part is fixed inside the tooth holder, and the connecting part of the rod part can be subjected to shearing force. When the shear force is too great, the risk of breaking the rod occurs.

SUMMERY OF THE UTILITY MODEL

The utility model provides a wear-resisting strenghthened type coal mining pick has solved above technical problem.

The utility model provides a scheme as follows of above-mentioned technical problem:

the wear-resistant reinforced coal mining cutting pick comprises a pick body, an alloy head and alloy beans, wherein the alloy head is arranged at one end of the pick body, the alloy beans are arranged on the outer side of the pick body, a groove is formed in the pick body, and reinforcing ribs are arranged on the surface of the pick body.

The utility model has the advantages that: through arranging the alloy beans around the alloy head at pick body head, strengthen its wear resistance, the effective live time of extension pick, and it is fluted and strengthening rib to distribute on the pick body, makes it obtain better rotation performance, can guarantee under multiple geological environment that wearing and tearing are even, avoids the appearance of eccentric wear condition.

On the basis of the technical scheme, the utility model discloses can also do following improvement.

Further, the alloy bean is positioned at one end of the tooth body close to the alloy head.

The beneficial effect of adopting the above further scheme is: the alloy beans are used for enhancing the wear resistance of the cutting pick and prolonging the effective service time of the cutting pick.

Furthermore, the grooves and the reinforcing ribs are distributed on the surface of the tooth body in a crossed manner.

The beneficial effect of adopting the above further scheme is: the tooth body can be ensured to be evenly worn in various geological environments.

Further, the alloy beans are uniformly distributed on the tooth body.

The beneficial effect of adopting the further scheme is that: the uniform abrasion of the tooth body is ensured.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.
