Description

Technical Field

[0001] The utility model relates to the technical field of coal gangue feeding in mining operations, and specifically relates to a coal gangue feeding device. Background Technique

[0002] During the coal mining process, the coal material fed contains not only light coal but also heavy coal gangue. During the coal mining process, it is necessary to continuously feed the coal material (including coal gangue) into the hopper and then from the hopper onto the conveyor belt. The coal material is transported on the conveyor belt and then transported to the processing equipment.

[0003] During the feeding process, since the coal material contains heavy coal gangue, when the material falls onto the conveyor belt of the conveying equipment, the heavier coal gangue directly impacts the conveyor belt. Especially for larger lump coal gangue materials, after falling and impacting the conveyor belt, under the greater impact force, the structures such as the frame and idler of the conveyor belt are prone to deformation and loosening, resulting in damage. Content of the Utility Model

[0004] To solve the above problems, that is, to solve the problems raised in the above background technique, the utility model proposes a coal gangue feeding device, including:

[0005] A material cylinder;

[0006] A fixed frame, fixedly installed on the outer surface of the material cylinder;

[0007] Support columns, two pairs in number, all fixedly installed on the lower end surface of the fixed frame;

[0008] Turning plates, one pair in number, all hinged to the lower end surface of the material cylinder;

[0009] A rotating rod, rotatably installed between a pair of the support columns;

[0010] A sleeve, hinged to the outer surface of the rotating rod;

[0011] A slider, slidably installed on the lower end surface of the turning plate;

[0012] A sliding rod, one end of which is inserted into the sleeve and the other end is hinged to the slider;

[0013] A compression spring, arranged inside the sleeve, and one end of which is fixedly connected to the inner wall surface of the sleeve and the other end is fixedly connected to one end of the sliding rod.

[0014] Preferably, a rotating shaft is rotatably installed inside the material cylinder, and a triangular prism guide block is arranged below the rotating shaft inside the material cylinder, and the triangular prism guide block is fixedly connected to the rotating shaft.

[0015] Preferably, a pair of tension springs are fixedly installed on the outer side wall surface of the flipping plate, and one end of each tension spring away from the flipping plate is fixedly connected to the lower end surface of the fixed frame.

[0016] Preferably, a chute is formed on the lower end surface of the flipping plate, and the slider is slidably installed in the chute.

[0017] The beneficial technical effects of the present utility model are as follows: Under the action of a pair of flipping plates, the falling coal materials can impact each other to offset the force generated during falling, prevent the transmission belt from being severely impacted when the coal materials fall, and avoid damage to the transmission belt.

[0018] Meanwhile, under the action of the rotating rod, the sleeve, the sliding rod, the compression spring, the slider and the tension spring, the flipping flipping plate can be supported, so that it flips slowly, facilitating the coal materials to fall not too fast, reducing the impact force on the transmission belt, and bringing convenience to people.

[0022] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0023] The present utility model provides a coal gangue feeding device, including:

[0024] Material cylinder 1;

[0025] The material cylinder 1 can temporarily store the coal materials;

[0026] Fixed frame 2, fixedly installed on the outer surface of the material cylinder 1;

[0027] Support columns 3, two pairs in number, all fixedly installed on the lower end surface of the fixed frame 2;

[0028] Under the action of the two pairs of support columns 3 and the fixed frame 2, the material cylinder 1 can be supported, so that the material cylinder 1 can be preset above the transmission belt of the external transmission device;

[0029] The turning plates 4, with a pair in number, are both hinged to the lower end face of the barrel 1;

[0030] The rotating rod 5 is rotatably installed between a pair of support columns 3;

[0031] The sleeve 6 is hinged to the outer surface of the rotating rod 5;

[0032] The slider 7 is slidably installed on the lower end face of the turning plate 4;

[0033] One end of the sliding rod 8 is inserted into the sleeve 6, and the other end is hinged to the slider 7;

[0034] The compression spring 9 is arranged in the sleeve 6, and one end is fixedly connected to the inner wall surface of the sleeve 6, and the other end is fixedly connected to one end of the sliding rod 8;

[0035] When the coal material falls, under the action of gravity, a pair of turning plates 4 can be turned open, and at the same time, the sliding rod 8 can slide into the sleeve 6, so that the compression spring 9 is compressed, which can play a buffering role in the falling of the coal material and prevent the falling coal material from damaging the conveyor belt of the external conveying equipment.

[0036] Specifically, a rotating shaft 10 is rotatably installed in the barrel 1, and a triangular prism guide block 11 is arranged below the rotating shaft 10 in the barrel 1, and the triangular prism guide block 11 is fixedly connected to the rotating shaft 10;

[0037] The triangular prism guide block 11 can guide the coal material in the barrel 1, and at the same time can buffer the coal material, so that it falls onto the upper end faces of a pair of turning plates 4 respectively. At the same time, the coal materials on the pair of turning plates 4 can collide with each other when falling, and the forces generated during the falling can be offset from each other, making it slower when falling onto the conveyor belt.

[0038] Specifically, a pair of tension springs 12 are fixedly installed on the outer side wall surface of the turning plate 4, and the ends of the tension springs 12 away from the turning plate 4 are fixedly connected to the lower end face of the fixed frame 2;

[0039] A pair of tension springs 12 can play a pulling role when the turning plate 4 turns, can slow down the turning time of the turning plate 4, and improve the buffering efficiency.

[0040] Specifically, a chute 13 is formed on the lower end face of the turning plate 4, and the slider 7 is slidably installed in the chute 13;

[0041] Under the action of the chute 13, the slider 7 can slide stably therein.

[0042] Working principle: When the coal material in the barrel 1 drops, first of all, the triangular prism guide block 11 can guide the dropping direction of the coal material so that it drops onto the upper end surfaces of a pair of turning plates 4 respectively. At this time, under the action of gravity, a pair of turning plates 4 turn over, and at the same time, the sliding rod 8 slides into the sleeve 6, compressing the compression spring 9, making the turning of the turning plates 4 slow down when they turn over and open. At the same time, when the turning plates 4 turn over, the tension spring 12 can pull the turning ends of the turning plates 4, which can slow down the speed of their turning. At this time, the coal materials on a pair of turning plates 4 collide with each other when they drop, which can cancel out the forces when the coal materials drop, forming a buffer. At this time, the coal materials drop onto the conveyor belt, and the conveyor belt conveys them, bringing convenience to people.
