Embodiment Construction

[0024] The invention discloses a shearer hydraulic breaker, such as figure 1 , 2 As shown, it includes a boom 4, a drum 12, a hydraulic motor 18 and an end cover 6. The boom includes a cylinder and an arm, and the axis of the cylinder is front and rear (corresponding to figure 2 up and down) extension, arms left and right (corresponding to figure 2 The left and right) extend and one end is connected to the rear of the cylinder. The coaxial rotating support of the drum is installed outside the front part of the cylinder. The end cover is coaxially fixed on the front end of the drum, and the drum and the end cover can rotate continuously around the axis of the cylinder of the jib as a whole. The hydraulic motor is fixedly installed in the barrel, that is, the housing of the hydraulic motor is relatively fixed to the barrel, and the output shaft of the hydraulic motor is coaxially connected with the end cover. The hydraulic motor is used to provide rotational power for the ...

Abstract

The invention relates to a coal mining machine fluid-driven crusher which comprises an arm frame, a drum, a hydraulic motor and an end cover. The arm frame includes a cylinder body and an arm portion,the axis of the cylinder body extends forward and backward, the arm portion extends left and right, one end of the arm portion is connected to the rear portion of the cylinder body, the drum is coaxially installed outside the front of the cylinder body in rotating and supported manners, the end cap is coaxially fixed at the front end of the drum, a shell of the hydraulic motor is fixedly mountedin the cylinder body, an output shaft of the hydraulic motor is coaxially connected with the end cover through connection of a first coupling, a clutch and a second coupling in sequence, and the clutch is a one-way overrunning type clutch. The coal mining machine fluid-driven crusher can replace a traditional motor-driven crusher, and solves the problems of poor impact resistance and the high failure rate of the existing motor-driven crusher.

Description

technical field [0001] The invention relates to a shearer crushing device, in particular to a shearer hydraulic breaker, which belongs to the technical field of coal mining equipment. Background technique [0002] Due to the unavoidable phenomena of slabs and roof fall in the coal mining face, large pieces of coal gangue are often produced. These coal gangue cannot pass through the bottom of the shearer body, so coal transportation is blocked, which seriously affects the production continuity of the coal mining face. Moreover, the greater the mining height of the working face, the larger the volume and quantity of large pieces of coal gangue, and the more prominent the problem of coal blocking. [0003] At present, a high-power crusher is usually installed on the shearer to crush the large pieces of coal that block the flow of coal. However, when the coal gangue block is large and the hardness is high, the crusher is extremely vulnerable to the instantaneous impact of high-...
