Planer cutter and coal planer

Abstract

The invention discloses a planer cutter and a coal planer. The planer cutter disclosed by the invention is applied to the coal planer, and comprises a cutter handle (100) and a cutter body (200). The planer cutter is characterized in that the cutter handle (100) and the cutter body (200) are connected with each other through a detachable mechanism; a hard alloy head (300) is further fixed at the tail end of the cutter body (200); and the cutter body (200) can be made of hard alloy. According to the planer cutter provided by the invention, the cutter handle (100) can be conveniently and individually machined, and the cutter body (200) and the cutter handle (100) can be subjected to independent thermal treatment conveniently, thus achieving proper rigidity, strength and roughness of the cutter body (200) and the cutter handle (100), and further achieving better comprehensive properties of the planer cutter. When the cutter body (200) is seriously abraded in a using process, the cutter body (200) can be only replaced, so that the cutter handle (100) can be repeatedly used, the entire using cost of the planer cutter can be reduced, and the use cost of the planer cutter can be reduced.

Description

technical field [0001] The invention relates to coal mining technology, in particular to a planer used for a coal plow and a coal plow including the planer. Background technique [0002] Coal plow is a commonly used coal mining equipment, especially in thin coal seam coal mining face, plow has obvious advantages. Coal plows include planers and planers. A knife holder is arranged on the planer head; the planer knife includes a knife handle and a knife body, and the root end of the knife handle cooperates with the knife holder to fix the planer knife on the planer head. [0003] In order to ensure the reliability of fixing between the planer and the planer, the guide handle has a specific structure to cooperate with the tool holder. Based on the specific working requirements of the plow, the end of the plow is usually fixed with a hard alloy head to form a cutting edge to meet the needs of coal seam cutting; at the same time, the handle and body of the plow should also have ...

AI Technical Summary

Problems solved by technology

[0004] In the process of use, although the planer has good comprehensive performance, the cutter body of the planer will also be worn; when the cutter body is severely worn, the planer will be scrapped; the planer will be replaced regularly, which makes the use of the plow more expensive. high
