[0002] After coal mining, it is necessary to use a belt conveyor to transport the coal out. However, when turning, two belt conveyors are needed for transfer. Some scattered coal will fall during the transfer process, which not only affects subsequent transportation but also causes waste. Therefore, a belt conveyor transfer buffer zone coal blocking device is proposed to solve the above-mentioned problems. Summary of the Invention

[0003] The purpose of the utility model is to solve the problem in the prior art that some scattered coal will fall during the conveyor transfer process, which not only affects the subsequent transportation but also causes waste, and to propose a coal blocking device in the transfer buffer zone of a belt conveyor.

[0010] In a possible design, one end of the feed plate is rotatably connected to a rotating shaft, and a plurality of rotating plates are fixedly sleeved on the outer wall of the rotating shaft, and the rotating plates are used in conjunction with the vertical plates.

[0011] In a possible design, a ratchet is provided on the outer wall fixing sleeve of the rotating shaft, and a pawl is provided on one side of the feeding plate, and the pawl is used in conjunction with the ratchet.

[0012] In one possible design, the adjustment assembly includes a screw threaded through a fixed block, one end of the screw is rotatably connected to a push plate, the push plate is slidably connected to the top of the frame, one end of the push plate is in contact with one side of the buffer plate, and the other end of the screw is fixedly connected to a handwheel.

The top of the feeding plate 5 is provided with an inclined slot 15. The frame 1 is placed below the two belt conveyors, below the connection position of the two belt conveyors;

[0031] When the coal ore falls, it is buffered and blocked by the buffer plate 4 and then falls on the chute 15 of the feed plate 5. It slides quickly through the chute 15 to facilitate subsequent collection.

[0032] A pair of fixing blocks 9 are provided on the top of the frame 1 , and the two fixing blocks 9 are symmetrically distributed on both sides of the frame 1 . An adjustment component is provided on each fixing block 9 , and the main function of the adjustment component is to adjust the angle of the buffer plate 4 .

[0033] The adjustment assembly includes a screw rod 8, which is threaded through a fixed block 9. One end of the screw rod 8 is rotatably connected to a push plate 10. The push plate 10 slides along the top of the frame 1. One end of the push plate 10 conflicts with one side of the buffer plate 4. When the angle of the buffer plate 4 needs to be adjusted, the hand wheel 2 can be rotated, and the hand wheel 2 will drive the screw rod 8 to rotate, and then the screw rod 8 will drive the push plate 10 to move laterally; since one end of the push plate 10 conflicts with the buffer plate 4, the movement of the push plate 10 will push the buffer plate 4, thereby completing the adjustment of the angle of the buffer plate 4.

[0034] A pair of knocking components are provided on the inner walls on both sides of the rectangular hole 11. The main function of the knocking components is to knock on the buffer plate 4 to shake off the residual coal slag. The knocking components include two tension springs 17, one end of the two tension springs 17 is fixedly connected to the same horizontal plate 16, and one end of the horizontal plate 16 is fixedly connected to the vertical plate 6; the horizontal plate 16 is slidably connected to the top of the feeding plate 5 to ensure that the horizontal plate 16 will not be obstructed when moving; at the same time, the interior of the horizontal plate 16 is also threaded with an adjusting screw 18, and one end of the adjusting screw 18 can push the buffer plate 4 to swing slightly; further, the end of the adjusting screw 18 is provided with a rubber pad to reduce noise.

[0035] When the coal ore slides out and falls from the feeding plate 5, the coal ore will push the rotating plate 7 to rotate, and the rotation of the rotating plate 7 will drive the vertical plate 6 to move horizontally, and the movement of the vertical plate 6 will drive the horizontal plate 16 to move horizontally; the horizontal plate 16 will stretch the tension spring 17 and shake continuously during the movement, and at the same time, the horizontal plate 16 will also drive the adjusting screw 18 to shake continuously, and the shaking of the adjusting screw 18 will push the buffer plate 4 to swing slightly, so that the remaining coal slag can be shaken off by the swing of the buffer plate 4, which is convenient for the subsequent collection process.

[0036] Example 2

[0037] refer to Figure 1-4 , improved on the basis of Example 1: a coal blocking device for the transfer buffer zone of a belt conveyor, the side wall of the feeding plate 5 is rotatably connected to the rotating shaft 20, the outer wall of the rotating shaft 20 is fixedly sleeved with multiple rotating plates 7, the rotating plates 7 are used in conjunction with the vertical plates 6, the outer wall of the rotating shaft 20 is also fixedly sleeved with a ratchet 21, and a pawl 19 is provided on the feeding plate 5. Furthermore, the pawl 19 is also provided with a reset torsion spring, and the pawl 19 is used in conjunction with the ratchet 21.

[0038] Furthermore, a rubber pad is provided on the surface of the buffer plate 4 to reduce the impact of the ore on the buffer plate 4 and reduce the noise generated by the ore falling.

[0039] When the ore slides down the chute 15, the ore hits the turn plate 7, and the turn plate 7 starts to rotate under the action of external force. The rotation of the turn plate 7 drives the rotating shaft 20 to rotate, and the rotation of the rotating shaft 20 drives the ratchet 21 to rotate; the rotation of the ratchet 21 drives the pawl 19 to slide on the tooth surface of the ratchet 21; when the turn plate 7 stops rotating, due to the cooperation of the pawl 19 and the ratchet 21, the ratchet 21 and the rotating shaft 20 will not reverse.
