[0020] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0021] Example:

[0022] Reference Figure 1-Figure 5 A pick type pick for coal mining machinery that is easy to disassemble and assemble, comprising a pick body 1, a tooth head 2 is provided at one end of the pick body 1, a tooth seat 3 is provided at the other end of the pick body 1, and both sides of the bottom end of the pick body 1 are provided with a resistance block 8, a slot 4 is provided on the top of the tooth seat 3 for convenient insertion of the pick body 1, an operating slot 5 that penetrates the slot 4 is provided on one side of the tooth seat 3, and two groups of grooves 6 and resistance grooves 7 that are respectively matched with the two groups of resistance blocks 8 are provided on the inner wall of the slot 4;

[0023] A thread groove 9 is provided near the bottom of the inner circle of the slot 4 and is threadedly connected with a rotating seat 10 . One end of the rotating seat 10 abuts against one end of the pick body 1 , and a turning handle 11 is provided on the outer circle of the other end of the rotating seat 10 .

[0024] Specifically, by inserting one end of the pick body 1 into the slot 4, the two groups of interference blocks 8 can slide along the two groups of grooves 6 to the bottom of the groove 6 respectively, and then by rotating the pick body 1, the pick body 1 can drive the two groups of interference blocks 8 to rotate to the inner sides of the two groups of interference grooves 7 respectively, and then, by rotating the handle 11, the handle 11 can drive the rotating seat 10 to rotate, and the rotating seat 10 can move along the slot 4 to one side of the pick body 1 under the action of the threaded connection with the slot 4, so that the rotating seat 10 and one end of the pick body 1 are in conflict, and during the continuous movement of the rotating seat 10, the two groups of interference blocks 8 can be pressed against the inner sides of the two groups of interference grooves 7, thereby completing the installation and fixation of the pick body 1, and when disassembly is required, it can be completed by reverse operation, and then through the above structure, the disassembly and assembly of the pick type pick is greatly facilitated, and damage to the pick type pick is effectively avoided.

[0025] The tooth head 2 is a cemented carbide cutter head, and the tooth head 2 is brazed to one end of the pick body 1 by means of brazing material. The strength of the tooth head 2 can be improved by providing the cemented carbide cutter head.
