The details are as follows:

[0012] (1) The utility model is provided with a feeding tray. When loading the hopper, it is only necessary to manually pour the raw materials into the discharge trough. The raw materials are accumulated to the bottom trough along the inclined surface of the discharge trough. At this time, the second motor is turned on to drive the rotating ring in the feeding tray to rotate. When the shovel plate on the rotating ring moves to the bottom trough, it scoops up the raw materials and enters the feeding bin. The raw materials rise in the feeding bin of the array along with the rotation of the rotating ring, pass the highest point of the feeding tray, and move to the sliding port. At this time, the shovel plate of the feeding bin contacts the discharge plate and transfers the raw materials to the feeding bin. The unloading plate is pressed down, and the unloading plate moves longitudinally on the spring seat. The raw materials slide out from the sliding port and slide into the hopper from the unloading plate. When the unloading plate moves to the bottom, all the raw materials slide into the hopper. At this time, the shovel plate continues to squeeze the unloading plate. When squeezing the inclined slide plate of the unloading plate, it forces the unloading plate to move horizontally along the lifting seat for the shovel plate to pass. After the shovel plate passes, the first spring and the second spring reset the unloading plate, and the unloading plate is ready to receive the next shovel plate to load the hopper.

[0013] (2) The utility model is provided with an extrusion bin. When the feeding plate feeds the hopper, the first motor operates to drive the feeding screw to rotate. The raw materials leaking from the leakage port are pushed forward by the feeding screw and fed into the processing device from the discharge port. During the filling and feeding process of the hopper and the extrusion bin, the feeding rate can be controlled by the operating speed of the first motor and the second motor to facilitate manual control.

The discharge trough 3 is in an inclined state with the bottom trough 19 being low and the other end being high. The raw materials are manually poured into the discharge trough 3, and the raw materials are accumulated to the bottom along the inclined surface of the discharge trough 3. There is a cavity inside the feeding tray 2 at the groove 19, and a rotating shaft 14 is rotatably provided at the center point of the feeding tray 2. A second motor 8 is fixedly provided at the rotating shaft 14 on one side of the feeding tray 2, and the output end of the second motor 8 is connected to the rotating shaft 14. A rotating ring 16 is fixedly provided on the rotating shaft 14 through a connecting frame 15. The second motor 8 drives the rotating ring 16 to rotate, and a circular array of shovel plates 17 are fixedly provided on the outer side of the rotating ring 16.

[0025] See also Figure 2 , 4The top of the feeding tray 2 is higher than the hopper 1. The hopper 1 is located on one side of the feeding tray 2 and is fixedly provided with a connecting baffle 9. The connecting baffle 9 extends to the feeding tray 2 and is connected with it. The feeding tray 2 is provided with a sliding port 20 between the connecting baffles 9. The raw materials in the feeding tray 2 are discharged from the sliding port 20. The connecting baffle 9 prevents the raw materials transported at the sliding port 20 from falling from both sides.

A lifting seat 22 is slidably arranged on the spring seat 10. The lifting seat 22 is located on one side of the spring seat 10 and is fixedly connected to the upper end of the first spring 21. The transverse cross-section of the spring seat 10 in the lifting seat 22 is rectangular, and its two sides are in contact with the two sides of the lifting seat 22 to prevent the stripping plate 11 from rotating when it is pressed down. A second spring 23 is fixedly arranged in the lifting seat 22. The two sides of the stripping plate 11 are inserted into the lifting seat 22 through sliders and are connected to the second spring 23. The stripping plate 11 is in an inclined state. It is located higher on one side of the sliding port 20 and lower on one side of the hopper 1, so that the raw materials can slide down along the discharge plate 11. The front section of the discharge plate 11 is located in a part of the feeding tray 2, which is a downwardly inclined inclined slide plate 12, and its bending part is located at the upper opening of the sliding port 20.

The inclination angle of the shovel plate 17 satisfies that when it contacts the discharge plate 11, it is lower on the side facing the discharge plate 11, so that when the shovel plate 17 moves to the sliding port 20, the material is fed. The raw materials in the bin 18 can slide along the shoveling plate 17 onto the discharge plate 11. The inclination angle and length of the inclined slide plate 12 meet the requirements that the shoveling plate 17 can squeeze it to retract into and pass through the hopper 1. The supporting force provided by the second spring 23 is greater than the supporting force of the first spring 21, so that when the shoveling plate 17 passes through the sliding port 20, it is pressed on the inclined slide plate 12. As the shoveling plate 17 moves, it pushes the discharge plate 11 to move downward and in the direction of the hopper 1. When the discharge plate 11 moves to the lowest end, the shoveling plate 17 and the inclined slide plate 12 slide relative to each other, and the discharge plate 11 continues to be pushed in the direction of the hopper 1 for the shoveling plate 17 to pass through.

When the discharge plate 11 moves to the bottom, all the raw materials slide into the hopper 1. At this time, the shovel plate 17 continues to squeeze the discharge plate 11. When squeezing the inclined slide plate 12 of the discharge plate 11, it presses the discharge plate 11 to move horizontally along the lifting seat 22, so that the shovel plate 17 can pass through. After the shovel plate 17 passes through, the first spring 21 and the second spring 23 reset the discharge plate 11, and the discharge plate 11 is ready to receive the next shovel plate 17 to load the hopper 1.
