Abstract

The utility model discloses a hopper releaser for a coal picker. The hopper releaser for the coal picker comprises a fixed substrate, wherein a rotational locking main shaft is arranged on the fixed substrate; the fixed substrate comprises a strip-shaped substrate main body; a pair of semicircular limiting protruded rings is arranged at the middle part of the substrate main body; a limiting through hole and a pair of limiting clamping grooves are arranged between the limiting protruded rings; the locking main shaft comprises a disk-shaped rotary frustum cone; and a rotary cylinder and a pair of limiting posts are arranged on the rotary frustum cone. According to the hopper releaser for the coal picker, which is disclosed by the utility model, the limiting clamping grooves in the middle part of the substrate main body and the pair of limiting posts on the rotary frustum cone are utilized; when a user pulls open a pull rod of the releaser, the limiting posts can be clamped into the limiting clamping grooves by rotating, so that the pull rod can be firmly fixed and is thoroughly prevented from being accidentally rotated.

Description

Hopper releaser for coal separator

Technical Field

The utility model relates to a coal mining equipment, more precisely, is a hopper releaser for coal picker.

Background

The coal separator is a machine for separating raw coal impurities, and is a very common coal mining and processing device. The hopper of the existing coal separator adopts a manual releaser, and after a user pulls open a pull rod of the releaser, the pull rod can rotate, so that the hopper can be accidentally released, and danger is caused.

Disclosure of Invention

The utility model discloses solve the technical problem that prior art exists mainly to a hopper releaser for coal picker is provided.

The above technical problem of the present invention can be solved by the following technical solutions:

the utility model provides a hopper releaser for coal picker, a hopper releaser for coal picker contain a fixed baseplate, fixed baseplate on be equipped with a rotatable locking main shaft, fixed baseplate contain a long banding base plate main part, the middle part of base plate main part be equipped with the spacing abrupt circle of a pair of semicircle, spacing abrupt circle between be equipped with a spacing through-hole and a pair of spacing draw-in groove, the locking main shaft contain a discoid rotatory round platform, rotatory round platform on be equipped with a rotatory drum and a pair of spacing post, rotatory drum run through spacing through-hole, the size of spacing post with spacing draw-in groove suit.

As the preferred embodiment of the present invention, the four corners of the substrate main body are respectively provided with a substrate through hole, and the substrate through holes are respectively provided with a fixing screw.

The utility model discloses a hopper releaser for coal picker utilizes a pair of spacing post on the spacing draw-in groove and the rotatory round platform at the middle part of board main part, after the user pulls open the pull rod of releaser, can go into spacing draw-in groove with spacing post card through the rotation, just so can firmly fix the pull rod, thoroughly prevents that it from taking place accident and rotating.
