[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-3 In this embodiment of the utility model, a coal mine belt conveyor with a dustproof structure includes a conveyor body 1, a shell 2, a feeding frame 3, two water pipes 5, a connecting rod 6, and two support mechanisms 7.

[0035] The conveyor body 1 can transport coal raw materials. The shell 2 is fixedly connected to one side of the top surface of the conveyor body 1. The side of the shell 2 has an opening slot 22. Several shielding curtains 23 are fixedly connected to the top surface of the opening slot 22. The shielding curtains 23 can shield the inside of the shell 2. A guide plate 1 21 is fixedly connected to the top of the inner side of the shell 2. The feeding frame 3 is fixedly connected to the inner side of the top of the feeding frame 3. Two guide plates 2 31 are fixedly connected to the inner side of the feeding frame 3. Rubber pads are fixedly connected to the top surface of both guide plate 1 21 and guide plate 2 31. The rubber pads can buffer the coal raw materials. Two water pipes 5 are fixedly connected to the inner side of the shell 2. Several nozzles 51 are connected to the side of the water pipes 5. The connecting rod 6 is set inside the shell 2. Several receiving plates 61 are fixedly connected to the side of the connecting rod 6. Two support mechanisms 7 can support the connecting rod 6.

[0036] Specifically, after the coal raw material enters the feeding frame 3, it can slide down the two guide plates 21 into the shell 2, and then fall into the shell 2. The coal raw material can fall onto the corresponding receiving plate 61 along the guide plates 21. Under the action of gravity, the connecting rod 6 and the receiving plate 61 can rotate, and the coal raw material will gradually fall onto the conveyor body 1. The conveyor body 1 transports the coal raw material, and the water pipe 5 can be connected to the water supply network pipeline. Water can be transported into the water pipe 5 through the water supply network pipeline, and the water can be sprayed from the nozzle 51. The spray can be applied to the coal material on the guide plate 21 through the nozzle 51 on the top water pipe 5, and to the coal material on the receiving plate 61 through the nozzle 51 on the bottom water pipe 5. Since the coal material can fall from the guide plate 21 onto the receiving plate 61, and the receiving plate 61 can drive the coal material to rotate, the coal material can roll and turn, thereby spraying and suppressing the dust of the coal material at the bottom layer, which is beneficial to improving the dust suppression effect.

[0037] Example 1

[0038] like Figures 1-2 As shown, in this embodiment, a connecting pipe 4 is fixedly connected to the top surface of the housing 2, and a plurality of suction pipes 41 communicating with the inside of the feeding frame 3 are connected to the side of the connecting pipe 4.

[0039] In practice, the two guide plates 31 can form an S-shaped falling channel inside the feeding frame 3 by blocking the flow. After connecting the connecting pipe 4 to the dust collection structure, the connecting pipe 4 can draw in the air inside the feeding frame 3 through the suction pipe 41, so that the air inside the feeding frame 3 enters the suction pipe 41 along the S-shaped falling channel, and is then transported to the dust collection structure through the connecting pipe 4. This can minimize the dust raised by the coal raw material falling on the guide plates 31 and drift out of the feeding frame 3, which is beneficial to improving the dust prevention effect.

[0040] likeFigures 3-4 As shown in the embodiment, the support mechanism 7 comprises a support base 71 and an adjusting frame 72.

[0041] The support base 71 is fixedly connected to the top surface of the conveyor body 1 and is located inside the shell 2.

[0048] In particular implementation, under the action of the torsion spring 75, the rolling disc 74 can be abutted against the conveyor belt of the conveyor body 1, when the conveyor body 1 is started and the conveyor belt of the conveyor body 1 conveys the coal raw materials, the conveyor belt of the conveyor body 1 can drive the rolling disc 74 to rotate, the rolling disc 74 can drive the connecting shaft 76 to rotate, the connecting shaft 76 can drive the connecting rod 6 to rotate through the gear one 62 and the gear two 77, thereby providing a certain assistance force for the rotation of the connecting rod 6, which is conducive to the smooth rotation of the connecting rod 6.
