On-line test system for mechanical properties of coal plow blade

Abstract

The invention provides a coal plough planing blade mechanical characteristic on-line testing device, and fundamentally solves the problem that mechanical characteristic data under a coal plough condition fails to be detected. According to the technical scheme, a coal plough cutter head comprises a cutter seat, a cemented carbide cutter head arranged on the front end of the cutter seat, a protection cover assembled on the cutter seat, and a cutter rod arranged on the bottom part of the cutter seat; the middle part of the cutter seat is provided with a square hole, and the vibration sensor is placed in the square hole through a strong magnetic base; a gap exists between the tail part of the cutter seat and the cutter rod; the square hole and the front end of the cutter seat form a tetragonal column, strain gage grooves are machined in the four surfaces of the tetragonal column, and the strain gage grooves are respectively equipped with strain gages I-III; and the front inner wall of the square hole is provided with the strain gage III; the protection cover is a U-shaped housing provided with a hook-shaped structure, the protection cover is embedded in the outer wall of the cutter seat through the front part of the cutter seat, and the hook-shaped structure is clamped to the rear part of the cutter seat and is fastened through a sunk screw. The coal plough planing blade mechanical characteristic on-line testing device has the advantages of simple structure, convenient usage, easy control, visual data detection, reliable detection result and the like.

Description

technical field

[0001] The invention relates to the field of coal mining machinery, in particular to an online testing system for the mechanical properties of a plow blade of a coal plow. Background technique

[0002] With the rapid development of my country's economy and society, the demand for coal resources is also increasing. Many thin coal seam coal resources have not been effectively utilized due to various reasons. Today, when coal resources are becoming more and more precious, the effective utilization of thin coal seam coal resources has become the only way for coal enterprises to increase production and efficiency, and effectively utilize national resources to benefit the country and the people.

[0003] The working face of the coal plow can realize the mechanized coal mining of thin and extremely thin coal seams. Workers do not have to follow the machine to operate, but can control it along the groove.

[0004] The planer is a common consumable part of the coal p...
