Figure 2 As shown in the figure, one end side of support frame 3 is fixed with motor one, the output end of motor one is rotatably through support frame 3 and one of the most edge I-shaped transmission rod 21 end portion fixed connection, motor one provides rotating power, drives corresponding one I-shaped transmission rod 21 rotation, the synchronous rotation of remaining I-shaped transmission rod 21, to drive conveying belt 2 cyclic rotation, can batch convey ore.

[0027] In order to avoid ore directly falling on conveying belt 2, it further includes buffer component, as shown in the figure, one end side of support frame 3 is fixed with motor one, the output end of motor one is rotatably through support frame 3 and one of the most edge I-shaped transmission rod 21 end portion fixed connection, motor one provides rotating power, drives corresponding one I-shaped transmission rod 21 rotation, the synchronous rotation of remaining I-shaped transmission rod 21, to drive conveying belt 2 cyclic rotation, can batch convey ore. Figure 2As shown, the buffer component has two rotating screws 5 arranged in the silo 1 opposite two side walls and a plurality of elastic rings 52, the outer wall of the silo 1 is fixed with a motor two, the output end of the motor two is rotatably penetrated through the side wall of the silo 1 and fixedly connected with the side wall of one end of the screw 5; the end of the two screws 5 is rotatably penetrated out of the side wall of the silo 1 and fixed with an I-shaped roller 4, and the transmission chain 41 is wound between the two I-shaped rollers 4. The motor two provides rotating power, which can drive one of the screws 5 to rotate, and through the transmission chain 41, the other screw 5 can be synchronously and directionally rotated.

[0028] As shown in Figure 3 and Figure 4 , the screw 5 is threadedly sleeved with a plurality of thread rings 51, the plurality of thread rings 51 are equally divided into a plurality of groups, two thread rings 51 are a group, and the radial outer wall of the elastic ring 52 is adjustably connected with the thread rings 51 on the two screws 5. Specifically, the outer wall of the elastic ring 52 and the outer wall of the thread ring 51 are both fixed with an extension rod, and the end of the extension rod is provided with a spherical block 54, the axial both ends of the material blocking rod 53 are both provided with a spherical groove capable of rotatably embedding the spherical block 54, and the material blocking rod 53 is rotatably connected with the spherical block 54 through the spherical groove, so as to realize the splicing between the elastic ring 52 and the thread ring 51. A plurality of protection structures similar to X-shaped structure are formed to receive large particle mineral materials and avoid the mineral materials falling from the lower opening of the silo 1 and falling on the conveying belt 2.

[0029] The thread rotation directions of the two thread rings 51 in the same group are opposite, when the screw 5 rotates forward, the two thread rings 51 in the same group are adjusted away from each other, thereby expanding the included angle between the two material blocking rods 53 connected with the two thread rings 51 in the same group, so as to stretch the elastic ring 52 to compensate for the position difference between the two material blocking rods 53 with the increased included angle, and the increased included angle between the adjacent two material blocking rods 53 allows the large particle mineral materials to fall on the conveying belt 2, thereby reducing the impact force when the mineral materials fall.

When the mineral material thrown into the material bin 1 falls and hits the elastic ring 52, it will directly hit the anti-blocking frame and slide along the outer wall of the inclined anti-blocking rod 55, and will not be stuck in the elastic ring 52. In this way, the mineral material stuck in the elastic ring 52 can be maximally avoided, and the elastic stretching adjustment of the elastic ring 52 is affected.
