[0025] like Figure 1-Figure 6 As shown, the utility model provides the following technical solutions: a material buffer device for a feed trough, comprising a feed trough 1 arranged obliquely, a feed hole 2 being opened on the side wall of the feed trough 1, a plurality of electric telescopic rods 5 being fixedly connected to the side wall of the feed trough 1, a support mechanism being fixedly connected to the output ends of the plurality of electric telescopic rods 5, a guide plate 6 being coupled to the top surface of the support mechanism, the top surface of the guide plate 6 being a corrugated surface, the electric telescopic rod 5 can drive the support mechanism to drive the guide plate 6 to move to seal the feed hole 2 and to decelerate the raw materials falling on the surface of the guide plate 6.

[0026] The cross section of the corrugated surface of the top surface of the guide plate 6 is semicircular and the radius gradually decreases from bottom to top, which increases the resistance to the falling coal particles while extending the flow path of the coal particles and reducing the flow speed of the coal particles.

[0027] The top surface of the guide plate 6 is provided with a plurality of S-shaped chutes 7, which lengthen the flow path of the coal particles and reduce the flow speed of the coal particles.

[0028] Please combine Figure 1 As shown, during use, the coal particles pass through the top of the feeding chute 1 and enter the feeding chute 1, flow along the inner wall of the feeding chute 1 to the guide plate 6, and the coal particles flow along the guide plate 6. The guide plate 6 blocks the feeding hole 2 and at the same time buffers the coal particles, thereby reducing the flow speed of the coal particles. There is no need to fall onto the buffer belt for buffering. The decelerated coal particles directly flow into the grading screen for processing, thereby reducing the flow speed of the coal particles and eliminating the need for the use of a buffer belt, thereby saving electricity.

[0029] When it is necessary to put a buffer belt into use to transport coal particles in other directions, the electric telescopic rod 5 is operated to start working. The output end of the electric telescopic rod 5 pulls the supporting mechanism to move, and the supporting mechanism drives the guide plate 6 to move to cancel the blockage of the discharge hole 2. The coal particles in the discharge trough 1 fall onto the buffer belt through the discharge hole 2. The buffer belt is driven by the motor to rotate and transport the coal particles falling on the buffer belt. The decelerated coal particles are transported to the screening machine.

[0030] Please combine Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, embodiment 1 of the support mechanism comprises a cavity 3 fixed at the output end of a plurality of electric telescopic rods 5, a plurality of guide rods 4 are slidingly provided in the cavity 3 in a close fit, both ends of the guide rods 4 are fixedly connected to the side walls of the discharge chute 1, a guide plate 6 is slidingly arranged in the cavity 3, a plurality of multi-section telescopic rods 8 are fixedly connected between the guide plate 6 and the cavity 3, the multi-section telescopic rods 8 are arranged in the cavity 3, a plurality of first compression springs 9 are fixedly connected between the guide plate 6 and the cavity 3, and the first compression springs 9 are sleeved on the multi-section telescopic rods 8.

[0031] Please combine Figure 1 As shown, during use, when the discharge hole 2 needs to be blocked, the staff operates the controller to start the electric telescopic rod 5 to work, and the electric telescopic rod 5 pushes the cavity 3 to slide on the guide rod 4, and the cavity 3 drives the multi-section telescopic rod 8 to move, and the multi-section telescopic rod 8 drives the guide plate 6 to move to block the discharge hole 2, and the coal mine particles enter the discharge chute 1 through the top of the discharge chute 1, flow along the inner wall of the discharge chute 1 to the guide plate 6, and then flow into the grading screen for processing after being decelerated by the guide plate 6.

[0032] When it is necessary to cancel the blockage of the discharge hole 2, the staff operates the controller to make the electric telescopic rod 5 start working, and the output end of the electric telescopic rod 5 drives the cavity 3 to move, and the cavity 3 indirectly drives the guide plate 6 to move and separate from the discharge hole 2 to cancel the blockage of the discharge hole 2. During the movement of the guide plate 6, it contacts the discharge chute 1, and the discharge chute 1 pushes the guide plate 6 to move and squeeze the first compression spring 9 to cause deformation.

[0033] Please combine Figure 3 As shown, embodiment 2 of the support mechanism comprises a cavity 3 fixed at the output end of a plurality of electric telescopic rods 5, a plurality of guide rods 4 are slidingly provided in close contact with the cavity 3, both ends of the guide rods 4 are fixedly connected to the side walls of the material discharge chute 1, one end of the guide plate 6 is hinged in the cavity 3 through a rotating shaft, the cross-section of the contact end of the guide plate 6 and the material discharge chute 1 is an arc surface, a plurality of second compression springs 10 are fixedly connected between the cavity 3 and the guide plate 6, and the second compression spring 10 is arranged on one side of the hinge between the guide plate 6 and the cavity 3.

[0034] Please combine Figure 3 As shown, during use, when it is necessary to block the discharge hole 2, the staff operates the controller to start the electric telescopic rod 5, and the electric telescopic rod 5 pushes the cavity 3 to slide on the guide rod 4. The cavity 3 drives the guide plate 6 to move to block the discharge hole 2 through the rotating shaft. The coal mine particles enter the discharge trough 1 through the top of the discharge trough 1, flow along the inner wall of the discharge trough 1 to the guide plate 6, and then flow into the grading screen for processing after the deceleration of the guide plate 6. At this time, the arc surface of the guide plate 6 fits the surface of the discharge trough 1. When it is necessary to increase the deceleration effect of the guide plate 6, the controller is operated to make the electric telescopic rod 5 continue to extend, and the output end of the electric telescopic rod 5 indirectly drives the guide plate 6 to move tilted downward, and the guide plate 6 gradually moves and separates from the surface of the discharge trough 1. At this time, the second compression spring 10 drives the guide plate 6 to rotate, so that the inclination angle of the guide plate 6 gradually decreases, thereby increasing the buffering force on the coal mine particles.

[0035] When it is necessary to cancel the blockage of the discharge hole 2, the staff operates the controller to make the electric telescopic rod 5 start working, and the output end of the electric telescopic rod 5 drives the cavity 3 to move, and the cavity 3 indirectly drives the guide plate 6 to move and separate from the discharge hole 2 to cancel the blockage of the discharge hole 2. During the movement of the guide plate 6, it contacts the discharge chute 1, and the discharge chute 1 pushes the guide plate 6 to rotate and squeeze the second compression spring 10 to deform.

[0036] The cross-sectional width of the S-shaped chute 7 increases gradually from top to bottom, thereby increasing the cross-sectional range of the lateral flow of the coal particles and reducing the flow velocity of the coal particles.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
