Description

Crushing device suitable for thin seam coal mining machine Technical Field The utility model relates to the technical field of coal mining equipment, in particular to a crushing device suitable for a thin seam coal mining machine. Background The crushing devices on the existing coal mining machine are generally provided with power devices such as crushing motors, speed reducing mechanisms and the like, and are large in size. The thin seam coal mining machine body is thinner, is limited by an installation space and a coal passing space, and adopts a power crushing device in a limited space, so that the crushing power is obviously insufficient, the reliability is low, and the failure rate is high. To solve this problem, the prior publication CN114798119B discloses a thin seam shearer body breaking device, which is greatly reduced in size by not providing a breaking motor, a reduction mechanism, and other power devices, so as to be suitable for being mounted on a thin machine body of a thin seam shearer. However, in actual use, massive coal or gangue is mostly accumulated in a coal passing channel above the scraper conveyor and close to the lower edge of the bottom of the machine body, and when the coal mining machine adopting the crushing device is used for crushing operation, on one hand, the situation that massive coal or gangue leaks is often found, and on the other hand, the crushing effect is poor, and the massive coal or gangue cannot be effectively crushed. Disclosure of utility model The utility model aims to solve the problems, and provides a crushing device suitable for a thin coal seam coal mining machine, which not only can meet the installation requirements of the thin coal seam coal mining machine, but also has good crushing effect. The purpose of the utility model is realized in the following way: The crushing device suitable for the thin seam coal mining machine is arranged above a coal passing channel of the thin seam coal mining machine and comprises strip-shaped crushing teeth, wherein a non-right-angle included angle is formed between the length direction of the crushing teeth and the coal conveying direction of the coal passing channel, and the crushing teeth face the coal passing channel. Wherein, the device also comprises a baffle; The baffle is used for being installed at one end of the crushing device, which is close to the outer side of the thin seam shearer, and the baffle is inclined downwards towards the side direction. The crushing teeth are uniformly distributed on the tooth mounting plate, and the crushing teeth protrude out of the tooth mounting plate. Wherein, the baffle is installed in the top of tooth mounting panel. The tooth mounting plate is connected with the mounting seat; the crushing device is arranged on the thin seam coal mining machine through the mounting seat. Wherein, the baffle with the mount pad is connected, is located the top of tooth mounting panel. Wherein, the tooth mounting plate with link to each other through a connecting plate between the mount pad. Wherein the included angle is between 30 degrees and 60 degrees. The baffle is close to the envelope line of one end of the outer side of the thin seam shearer and is mapped to the outer side of the coal passing channel along the direction perpendicular to the coal passing channel. Wherein, broken tooth along the fortune coal direction of coal passageway is progressively closer to coal passageway. The utility model has the beneficial effects that by adopting the strip-shaped crushing teeth, and the crushing teeth and the coal passing channel are obliquely arranged at a non-right angle, the lump coal or gangue transported on the coal passing channel can smoothly enter the crushing device, and the contact area between the strip-shaped crushing teeth and the lump coal or gangue can be increased, so that the crushing effect is greatly improved.
