[0006] Furthermore, the lower end of the piston rod passes through the inner wall of the shelf and extends to the interior of the cavity, the bottom of the piston rod is elastically connected to the inner wall of the cavity through a spring, several of the cavities are connected to the interior of the airbag through vents, the discharge port is located between the several cavities, several of the cavities are located on the side where the two airbags are close to each other, and the rotating shaft is located above the slider.

[0007] Furthermore, the mounting mechanism includes two connecting plates, the sides of the two connecting plates close to each other are provided with a first slide groove and a second slide groove, the sides of the two connecting plates away from each other are provided with a groove, and bolts are arranged inside the groove.

[0008] Furthermore, the second slide groove is located below the first slide groove, the bolt passes through the inner wall of the groove and extends to the side of the connecting plate away from the connecting plate, and the second slide groove passes through the inner wall of the connecting plate and extends to the side of the connecting plate away from the bolt.

[0009] Furthermore, the receiving shelf is located between two connecting plates, the rotating shaft is slidably connected to the first slide slot, the sliding block is slidably connected to the inner wall of the second slide slot, and the side of the sliding block close to the bolt abuts against the inner wall of the second slide slot.

[0010] Furthermore, the adjustment mechanism includes two motors, and the sides of the two motors that are away from each other are rotatably connected to a driving gear, and a driven gear is meshed below the driving gear. The sides of the two driven gears that are close to each other are fixedly connected to a telescopic cylinder, and the bottom of the telescopic cylinder is slidably connected to a telescopic rod.

[0011] Furthermore, the two telescopic cylinders are fixedly connected via a connecting rod, the motor is fixedly connected to the inner wall of the connecting plate, and the two driving gears are located on the side of the two connecting plates away from each other.

[0012] Furthermore, the two telescopic cylinders are located between the two connecting plates, the telescopic cylinders are located on a side of the receiving shelf close to the rotating frame, and the bottom of the telescopic rod is rotatably connected to the rotating frame.

[0015] Compared with the prior art, the advantages of the present invention are: The present invention reduces the impact force on the docking shelf by arranging structures such as cavities and air bags. After the coal generates impact force on the buffer frame, the impact force is absorbed by the air pressure in the cavity and the elastic force of the spring, and the movement of the buffer frame is buffered at the same time. When the impact force on the buffer frame is large, the air pressure in the vent hole will cause the top of the air bag to expand to a degree that it is against the bottom of the buffer frame, thereby supporting the bottom of the buffer frame, further buffering the buffer frame, and preventing the bottom of the buffer frame from colliding with the inner wall of the docking shelf, causing damage to the buffer frame and generating noise, and improving the stability of the device.

[0016] By setting up structures such as driven gears and telescopic cylinders, it is convenient to adjust the position of the docking shelf. The docking shelf is driven downward by the telescopic cylinder to reduce the distance between the discharge port and the conveyor belt, so that the coal can fall onto the conveyor belt more concentratedly through the discharge port, resulting in better receiving effect and reducing the possibility of coal scattering around during the falling process. At the same time, the smaller drop makes the speed of the coal falling on the conveyor belt after being decelerated by the buffer mechanism relatively lower, reducing the impact force on the conveyor belt and extending the service life of the device. When the unloading speed of the coal on the head of the transfer machine is fast, the motor can be started so that the opening of the buffer frame can cover the position of the guide plate away from the side of the head of the transfer machine, thereby avoiding the situation where the faster coal flies out and scatters from the top of the docking shelf, reducing the loss of coal during the transportation process and increasing the effective transportation volume of coal.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The bottom of the piston rod 104 is elastically connected to the inner wall of the cavity 102 through the spring 103. The plurality of cavities 102 are connected to the inside of the airbag 107 through the vent hole 106. The discharge port 108 is located between the plurality of cavities 102. The plurality of cavities 102 are located on the side where the two airbags 107 are close to each other. The rotating shaft 109 is located above the slider 110. The main body mechanism 4 includes a transfer machine head 401, and side plates 402 are fixedly connected to both sides of the transfer machine head 401. A material guide plate 403 is fixedly connected to the transfer machine head 401, and a conveyor belt 404 is arranged below the transfer machine head 401.

The conveyor belt 404 is located below the receiving shelf 101; By setting up the cavity 102 and the air bag 107 and other structures, the impact force on the docking shelf 101 is reduced. After the coal generates an impact force on the buffer frame 105, the buffer frame 105 will drive the piston rod 104 downward, squeezing the spring 103 and the space inside the cavity 102, so that the air pressure inside the cavity 102 increases, wherein the gas will enter the air bag 107 through the vent 106, so that the air bag is gradually filled, and the impact force is absorbed by the air pressure in the cavity 102 and the elastic force of the spring 103, and at the same time, the movement of the buffer frame 105 is buffered. When the impact force on the buffer frame 105 is large, the air pressure in the vent 106 will make the top of the air bag 107 expand to the extent that it is against the bottom of the buffer frame 105, support the bottom of the buffer frame 105, further buffer the buffer frame 105, and at the same time avoid the bottom of the buffer frame 105 from colliding with the inner wall of the docking shelf 101, causing damage to the buffer frame 105 and generating noise, and improve the stability of the device.

[0024] See also Figure 1-4As shown, the mounting mechanism 2 includes two connecting plates 201, and the first slide groove 202 and the second slide groove 203 are provided on the sides of the two connecting plates 201 that are close to each other, and the grooves 204 are provided on the sides of the two connecting plates 201 that are away from each other. Bolts 205 are arranged inside the grooves 204, and the second slide groove 203 is located below the first slide groove 202. The bolts 205 penetrate the inner wall of the groove 204 and extend to the side of the connecting plate 201 away from the connecting plate 201. The second slide groove 203 penetrates the inner wall of the connecting plate 201 and extends to the side of the connecting plate 201 away from the bolts 205. The shelf 101 is located between the two connecting plates 201, and the rotating shaft 109 is slidably connected to the first slide groove 202, and the slider 110 is slidably connected to the inner wall of the second slide groove 203, and the side of the slider 110 close to the bolt 205 abuts against the inner wall of the second slide groove 203. The adjusting mechanism 3 includes two motors 301, and the sides of the two motors 301 that are away from each other are both rotatably connected with a driving gear 302, and a driven gear 303 is meshed below the driving gear 302. The sides of the two driven gears 303 that are close to each other are both fixedly connected with a telescopic cylinder 304, and the bottom of the telescopic cylinder 304 is slidably connected with a telescopic rod 305. The two telescopic cylinders 304 are fixedly connected by a connecting rod, and the motors 301 are fixedly connected to the inner wall of the connecting plate 201. The two driving gears 302 are located on the side of the two connecting plates 201 that are away from each other, and the two telescopic cylinders 304 are located between the two connecting plates 201. The telescopic cylinder 304 is located on the side of the receiving shelf 101 close to the rotating frame 111, and the bottom of the telescopic rod 305 is rotatably connected to the rotating frame 111; By setting up the driven gear 303 and the telescopic cylinder 304 and other structures, it is convenient to adjust the position of the docking shelf 101. The telescopic cylinder 304 makes the telescopic rod 305 move downward and push the rotating frame 111 downward, driving the docking shelf 101 to move downward inside the first slide 202 through the rotating shaft 109, reducing the distance between the discharge port 108 and the conveyor belt 404, so that the coal can pass through the discharge port 108 and fall onto the conveyor belt 404 in a more concentrated manner, so that the receiving effect is better and the possibility of coal scattering around during the falling process is reduced. At the same time, the smaller drop makes the speed of the coal falling on the conveyor belt after being decelerated by the buffer mechanism 1 relatively lower, reducing the impact force on the conveyor belt 404 and extending the service life of the device. When the unloading speed of the upper coal is faster, the motor 301 can be started to rotate the driving gear 302. The rotation of the driving gear 302 will drive the driven gear 303 to rotate. The rotation of the driven gear 303 will drive the telescopic cylinder 304 to rotate, and the telescopic rod 305 will push the rotating frame 111 at the bottom of the receiving rack 101 in the direction away from the head 401 of the transfer machine, so that the buffer frame 105 rotates around the rotating shaft 109, and the slider 110 is moved out from the inside of the second slide groove 203, so that the receiving rack 101 is tilted, so that the opening of the buffer frame 105 can cover the position of the guide plate 403 away from the side of the transfer machine head 401, to avoid the situation where the faster coal flies out and scatters on the top of the receiving rack, thereby reducing the loss of coal during the transportation process and increasing the effective transportation volume of coal.

[0025] Working principle: first, when the coal is unloaded from the head of the transfer machine 401 to the receiving rack 101, it will fall into the buffer frame 105 along the inclined surface of the guide plate 403, and then fall from the discharge port 108 opened at the bottom of the buffer frame 105 to the conveyor belt 404 below it. In this process, the coal will generate an impact force on the buffer frame 105, so that the buffer frame 105 drives the piston rod 104 downward, squeezes the spring 103 and the space inside the cavity 102, and makes the air inside the cavity 102 empty. The pressure increases, and the gas enters the airbag 107 through the vent hole 106, so that the airbag is gradually filled, and the impact force is absorbed by the air pressure in the cavity 102 and the elastic force of the spring 103, and the movement of the buffer frame 105 is buffered at the same time. When the impact force on the buffer frame 105 is large, the air pressure in the vent hole 106 will expand the top of the airbag 107 to the extent that it is against the bottom of the buffer frame 105, so as to support the bottom of the buffer frame 105 and further buffer the buffer frame 105; When the tunnel is at a high height, the telescopic rod 305 can be moved downward by the telescopic cylinder 304 and the rotating frame 111 can be pushed downward, driving the receiving rack 101 to move downward inside the first chute 202 through the rotating shaft 109, thereby reducing the distance between the discharge port 108 and the conveyor belt 404, so that the coal can pass through the discharge port 108 and fall onto the conveyor belt 404 in a more concentrated manner; When the unloading speed of the coal on the transfer machine head 401 is faster, the motor 301 can be started to rotate the driving gear 302. The rotation of the driving gear 302 will drive the driven gear 303 to rotate. The rotation of the driven gear 303 will drive the telescopic cylinder 304 to rotate, and push the rotating frame 111 at the bottom of the receiving shelf 101 away from the transfer machine head 401 through the telescopic rod 305, so that the buffer frame 105 rotates around the rotating shaft 109, and the slider 110 moves out from the second slide groove 203, so that the receiving shelf 101 is tilted, so that the opening of the buffer frame 105 can cover the position of the guide plate 403 away from the side of the transfer machine head 401, and the faster coal can be received.
