Description

Technical Field

[0001] The utility model relates to the technical field of coal mining equipment, in particular to a filling mechanism for filling a coal mining conveyor. Background Art

[0002] Coal is the main energy source in my country. As a traditional and basic industry of the national economy, the coal industry plays an important role in the development of the national economy, driving my country's rapid economic growth and social progress.

[0003] However, in coal mining, the mined coal needs to be placed on a coal conveyor, which transports coal in the form of a conveyor belt. During use, we found that coal piled arbitrarily on the conveyor belt is prone to collapse during transportation. The reason is that the coal is directly piled and is relatively loose. To this end, we designed a filling mechanism for filling coal conveyors. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a filling mechanism for filling a coal mining conveyor.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A filling mechanism for filling a coal mining conveyor, comprising a frame, the frame being mounted on the coal mining conveyor, and a pressing mechanism for pressing coal being mounted inside the frame;

[0007] The pressing mechanism includes side pressure plates located on both sides of the inner wall of the frame, and two electric push rods are installed on both sides of the outer wall of the frame for realizing the movement of the side pressure plates;

[0008] The top of the side pressure plate is rotatably connected to an upper pressure plate through an axis, a gear is coaxially fixed to the upper pressure plate, and a rack meshing with the gear is installed on the frame.

[0009] The above structural design can be installed on a coal mine conveyor. Through the frame structure, the two unfolded upper pressure plates can facilitate the delivery of coal into the frame to prevent the delivery from being scattered. The structure is simple and more practical.

[0010] As a further solution of the present invention, the electric push rod is fixed to the outer wall of the frame, and a through hole for the output end of the electric push rod to pass through is opened on the frame, and the output end of the electric push rod is fixed to the outer wall of the side pressure plate.

[0011] As a further solution of the present invention, an outlet is provided at one end of the frame.

[0012] As a further solution of the present invention, a notch is provided on the top of the frame at a position away from the discharge opening, and the rack is fixed in the notch.

[0013] As a further solution of the present invention, a partition is fixed to the top of the inner wall of the frame near the rack. The partition serves as a movable protective rack and gear. A second slide groove is provided on the partition, and the shaft connected to the gear passes through the second slide groove.

[0014] As a further solution of the present invention, pressure blocks are fixed to the sides of the two side pressure plates that are close to each other to increase the pressing effect.

[0015] As a further solution of the present invention, a first slide groove is provided on the outer wall of the frame above the discharge port, and a guide block is coaxially fixed to the upper pressure plate. The guide block is slidably arranged in the first slide groove, and the first slide groove supports the guide block, which can play a certain supporting effect.

[0016] As a further solution of the present invention, mounting feet are fixed at the four corners of the outer wall of the frame, and the mounting feet are fixed to the frame of the coal mine conveyor.

[0017] The beneficial effects of the utility model are:

[0018] The utility model: due to the adoption of the set frame, electric push rod and pressing mechanism, the electric push rod works, so that the two side pressure plates approach each other, and a certain pressure is applied to both sides of the coal. When the two side pressure plates approach each other, the gear moves on the rack, so that the two upper pressure plates drive the pressure blocks to flip, and a certain pressure is applied to the top of the coal mine. After pressing, the two side pressure plates move away from each other, the upper pressure plate opens, and the coal mine conveyor works, so that the coal mine is moved out from the discharge port. Through the above design, the coal mine can be filled and a certain pressure can be achieved, so that the coal mine has a certain degree of tightness, and can have a certain effect of avoiding collapse during the coal mine transportation process.

[0019] The utility model: the structural design can be installed on the coal mine conveyor. Through the frame structure, the two unfolded upper pressure plates can facilitate the delivery of coal into the frame to prevent the delivery from being scattered. The structure is simple and more practical. BRIEF DESCRIPTION OF THE DRAWINGS
