Description

Technical Field

[0001] The invention relates to the technical field of coal mine crushing, and in particular to a dust collection mechanism for a coal mine crusher. Background Art

[0002] Coal mine crusher is a crushing equipment that breaks coal blocks and grinds them into coal powder. It is a necessary production and processing machine in the production process of coal mines. It can break large coal blocks to facilitate the transportation and processing of coal mines in the later stage. However, there are some shortcomings in the use of existing coal mine crushers; The existing coal mine crusher will generate a lot of dust when crushing coal blocks, causing the dust to fly everywhere, so that nearby workers will absorb more coal mine dust, thereby causing irreversible damage to the lungs of nearby workers. The flying coal mine dust will scatter on the ground and inside the machine, which not only damages the surrounding environment, but also makes it inconvenient for workers to clean it later. In addition, the coal mine dust adheres to the machine, which will shorten the service life of the machine. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a dust collection mechanism for a coal mine crusher to more accurately solve the problem of dust generated by coal mine crushing flying everywhere.

[0004] The present invention is achieved through the following technical solutions: The present invention proposes a dust collection mechanism for a coal mine crusher, comprising a collection frame, a horizontal plate is fixedly arranged inside the collection frame, a clamping block is fixedly arranged on the inner wall of the horizontal plate, a dust collector is movably arranged inside the collection frame, a connecting pipe is rotatably arranged on the top end of the dust collector, a suction nozzle is fixedly arranged on the end of the connecting pipe away from the dust collector, a threaded rod is rotatably arranged on the inner wall of the suction nozzle, a threaded sleeve is threadedly connected to the surface of the threaded rod, a connecting rod is rotatably arranged on the top end of the threaded sleeve, and a movable plate is rotatably arranged on the end of the connecting rod away from the threaded sleeve.

[0005] Furthermore, a revolving door is fixedly provided on the front of the collection frame, and a glass window is fixedly provided on the surface of the revolving door, so that the inside of the collection frame can be opened and closed by the revolving door, and the worker can view the inside of the collection frame through the glass window.

[0006] Furthermore, the connecting pipe is arranged in a C-shaped structure as a whole, and the middle part of the connecting pipe is arranged as a telescopic structure, so that the length of the connecting pipe can be changed, thereby facilitating the suction nozzle to be better installed at the feed port of the coal mine crusher.

[0007] Furthermore, rectangular notches are provided on both sides of the suction nozzle, and the notches are matched with the movable plate, so that the movable plate can move laterally, thereby preventing surface motion interference.

[0008] Furthermore, the surface of the threaded rod is provided with two groups of threads, and the two groups of threads are symmetrically distributed. The surfaces of the two groups of threads are threadedly connected with a group of threaded sleeves, ensuring that when the threaded rod is rotated, the threads in different directions can drive the two groups of threaded sleeves to move in different directions.

[0009] Furthermore, a discharge port is fixedly provided at the bottom end of the vacuum cleaner, and the discharge port is movably plugged into the interior of the transverse plate, so as to ensure that the vacuum cleaner can collect the adsorbed dust in the collection frame through the discharge port.

[0010] Furthermore, a circular notch is fixedly provided at the center of the horizontal plate, and a clamping block is fixedly provided inside the circular notch, so that the discharge port of the vacuum cleaner can be conveniently inserted into the circular notch at the center of the horizontal plate by using the clamping block.

[0011] Furthermore, three groups of rubber blocks are fixedly arranged on the surface of the clamping block, and an automatic telescopic rod is fixedly connected between the cross plate and the clamping block, so that the automatic telescopic rod is conveniently used to drive the clamping block and the rubber blocks on its surface to firmly clamp the discharge port of the vacuum cleaner.

[0012] Furthermore, there are four groups of connecting rods in total, and the four groups of connecting rods are distributed in a diamond structure as a whole, ensuring that when the threaded sleeve moves, the connecting rods can drive the moving plate to move synchronously.

[0013] Furthermore, a turntable is fixedly provided at one end of the threaded rod, and the turntable is arranged outside the suction nozzle, so that a worker can manually rotate the turntable of the threaded rod.

[0014] Beneficial effects of the present invention: The present invention can use the vacuum cleaner and the collection frame to absorb the dust generated by the coal mine crushing, and then use the collection frame to collect the dust, so as to facilitate the centralized treatment of the dust generated by the coal mine crushing, avoid the dust generated by the coal mine crushing from flying everywhere and causing harm to the health of the workers, and reduce the workers' subsequent cleaning service work.

[0015] The present invention drives the movable plate to move horizontally by rotating the threaded rod, so that the movable plate can clamp the feed port of the coal crusher during movement, so that the suction nozzle can be installed at the center position above the feed port of the coal crusher of different sizes, thereby ensuring that the suction nozzle and the connecting pipe can better absorb the dust generated by the coal crushing, thereby ensuring the high efficiency of dust absorption.

A threaded rod 5 is rotatably set on the inner wall of the suction nozzle 4, and a turntable is fixedly set at one end of the threaded rod 5, and the turntable is set outside the suction nozzle 4, so that the worker can manually rotate the turntable of the threaded rod 5. The surface of the threaded rod 5 is threadedly connected with a threaded sleeve 6, and a connecting rod 7 is rotatably set on the top of the threaded sleeve 6. A movable plate 8 is rotatably set at one end of the connecting rod 7 away from the threaded sleeve 6. Rectangular notches are set on both sides of the suction nozzle 4, and the notches are matched with the movable plate 8, so that the movable plate 8 can be moved horizontally, thereby interfering with the surface movement.

[0020] As an implementation method in this embodiment, Figure 2As shown, the surface of the threaded rod 5 is provided with two groups of threads, and the two groups of threads are symmetrically distributed. The surfaces of the two groups of threads are threadedly connected with a group of threaded sleeves 6, ensuring that when the threaded rod 5 is rotated, the threads in different directions can drive the two groups of threaded sleeves 6 to move in different directions; there are four groups of connecting rods 7, and the four groups of connecting rods 7 are distributed in a diamond structure as a whole, ensuring that when the threaded sleeves 6 move, the connecting rods 7 can drive the moving plate 8 to move synchronously.

[0021] As an implementation method in this embodiment, Figure 3 As shown, a discharge port is fixedly provided at the bottom end of the vacuum cleaner 2, and the discharge port is movably plugged into the inside of the transverse plate 9, ensuring that the vacuum cleaner 2 can collect the adsorbed dust in the collection frame 1 through the discharge port; a circular notch is fixedly provided at the center position of the transverse plate 9, and a clamping block 10 is fixedly provided inside the circular notch, so that the discharge port of the vacuum cleaner 2 can be conveniently plugged into the circular notch at the center position of the transverse plate 9 by using the clamping block 10; three groups of rubber blocks are fixedly provided on the surface of the clamping block 10, and an automatic telescopic rod is fixedly connected between the transverse plate 9 and the clamping block 10, so that the automatic telescopic rod is conveniently used to drive the clamping block 10 and the rubber blocks on its surface to firmly clamp the discharge port of the vacuum cleaner 2.
