The separating plate 322 is arranged obliquely along the conveying direction of the material, and the material passes through the upper end and the lower end of the separating plate 322 in front and back along the conveying process of the conveying channel 31.

In order to facilitate a clearer understanding of the material delivery system provided in the embodiments of the present application, the main features of the material delivery system are described as follows:

the material directional arrangement device 20 comprises a material groove 21 and a guide wheel 22 positioned in the material groove 21. The bottom of the trough 21 is called a trough 212, the width of the trough 212 is slightly larger than the width of the material and smaller than the length of the material, the bottom of the trough 21 extends upwards to form an expanding trend, the top of the trough 21 is called a trough peak 213, and the width of the trough peak 213 is larger than the width of the trough 212 and still smaller than the length of the material. The materials are arranged in the trough 212 along the width direction, move along the length direction and are in a stable state, if the materials are not in the stable state, the guiding due to the width variation of the trough 21 during the movement along the trough 21 will automatically transition to the steady state, and finally, the stable state is achieved, the guide wheel 22 is arranged above the material groove 21 and between two adjacent material grooves 21, when the guide wheel 22 rotates, the direction of movement of the surface facing the trough 21 is opposite to the direction of movement of the material in the trough 21, and if part of the material rides up the trough peak 213, when the material moves into contact with the guide wheel 22, since the surface of the guide wheel 22 moves in the direction opposite to the moving direction of the material, the guide wheel 22 will give a force to the part of the material overlapping the trough peak 213 in the direction opposite to the moving direction of the material, so that the part of the material overlapping the trough peak 213 moves toward the front end of the trough 21, thereby pushing the material back to the trough 212 of the trough 21. Silo 21 has the function of arranging the material neatly in unison according to same direction, and the material conveys behind the front end of silo 21 from feeder equipment 10, and the most material can directly get into the steady state of trough 212 or through the in-process that removes in silo 21 gets into the steady state of trough 212, and the in-process that few part do not be in the steady state is continuing to move down, when the leading wheel 22, can be pushed back to the steady state of trough 212 by leading wheel 22. That is, after the materials pass through the material directional arrangement device 20, all the materials are arranged into a queue which is uniformly arranged in the same direction and moves forwards. A plurality of aligned rows of troughs 21 move forward into the material separation apparatus 30.

The material separation device 30 comprises a separation plate 322, a separation shaft 321, a separation bracket 325 and an adjusting bolt, wherein the separation plate 322 is obliquely arranged along the material conveying direction, passes through the upper end and the lower end of the separation plate 322 in a front-back manner, the distance between the upper end and the conveyor belt 33 is larger than that between the lower end and the conveyor belt 33, the distance between the lower end of the separation plate 322 and the conveyor belt 33 is larger than that between the thickness of one material and less than that between two materials, the distance between the upper end and the conveyor belt 33 is larger than that between the upper end and the thickness of two materials, the distance between the upper end and the conveyor belt 33 is generally set to be larger than that between the upper end and the thickness of two materials, the upper end of the separation plate 322 is arranged on the separation bracket 325 through the separation shaft 321, the separation bracket 325 is arranged on the partition boards, the upper end portion rises naturally. The adjusting bolt passes through the separating bracket 325 and abuts against one end of the separating plate 322, so that the separating plate 322 can only rotate around the separating shaft 321 in the material conveying direction, and can be blocked by the adjusting bolt when rotating in the opposite direction, thereby keeping the lower end of the separating plate 322 at a fixed distance from the conveyor belt 33. When the stacked materials pass through the separating structure 32, the materials stacked on the separating structure contact the lower end of the separating plate 322 and a part of the separating plate 322 extending from the lower end to the upper end, the separating plate 322 applies a force to the materials stacked on the separating structure to push the materials downward, the materials stacked on the separating structure are separated into material queues arranged in front and back to be conveyed forward continuously, and meanwhile, the separating plate 322 can rotate around the separating shaft 321, so that the situation that the materials are stuck cannot occur. By adjusting the position of the adjusting bolt on the separating bracket 325, the protruding amount of the adjusting bolt abutting against the separating plate 322 can be changed, so that the distance between the separating plate 322 and the conveyor belt 33 can be changed to adapt to materials with different thicknesses. By varying the moment of the lower end portion and the moment of the upper end portion, the amount of force applied by the separating plate 322 to the material superimposed thereon can be varied, so that optimum separation of different materials can be achieved.
