[0033] As a preferred solution, further, the driving assembly 99 includes a mounting plate 991 mounted on the top of the right side wall of the box body 92, a motor 992 electrically connected to the controller 6 is mounted on the upper surface of the mounting plate 991, a fourth rotating shaft 993 is mounted on the output end of the second motor 992, and a third bevel gear 994 and a rotating rod 995 are respectively mounted on the upper and lower ends of the outer wall of the fourth rotating shaft 993, and the third bevel gear 994 is meshed with the second bevel gear 945. Under the drive of the second motor 992, through the third bevel gear 994, the second bevel gear 945 and the first The transmission between the bevel gears 943 can make the second rotating shaft 942 rotate. The end of the rotating rod 995 away from the fourth rotating shaft 993 is equipped with a pin 996 which is plugged into the inner cavity of the push plate 98. The pin 996 is driven to make a circular motion by the second motor 992. While the pin 996 slides back and forth in the inner cavity of the push plate 98, it can move the paddle plate 96 back and forth to change the falling direction of the material. The second motor 992 drives the pin 996 to rotate through the rotating rod 995. The diameter of the rotation trajectory is less than or equal to the inner diameter of the discharge barrel 91, ensuring that the paddle plate 96 always moves directly below the discharge barrel 91.

[0034] Working principle:

[0035] Step 1: put the screened raw materials or the mixed raw materials into the putting bucket 101, and drive the first motor 103 to drive the screw conveying rod 104 to rotate through the controller 6, so that the materials are lifted in the conveying cylinder 102 under the push of the screw conveying rod 104, and the materials are conveyed to the material box 7;

[0036] Step 2: The material trough or processing equipment containing the raw materials is placed on the support platform 3. The solenoid valve 8 and the second motor 992 are started through the controller 6. The solenoid valve 8 opens the bottom of the material box 7, and the raw materials in the material box 7 fall through the discharge barrel 91. During the discharge process, the second motor 992 drives the fourth rotating shaft 993 to drive the third bevel gear 994 and the rotating rod 995 to rotate. Under the transmission of the third bevel gear 994, the second bevel gear 945 and the first bevel gear 943, the second rotating shaft 942 can be rotated to prevent the raw materials from being blocked in the discharge barrel 91.

[0037] The rotating rod 995 drives the pin 996 to make a circular motion, and the pin 996 slides back and forth in the inner cavity of the push plate 98. Since the guide rod 95 limits the paddle plate 96, the pin 996 can paddle the push plate 98 to move back and forth, thereby making the paddle plate 96 move back and forth. The paddle plate 96 changes the falling direction of the raw materials, allowing the raw materials to fall evenly into the material trough or processing equipment, thereby realizing the prevention of blockage in the discharge of raw materials.

[0038] Step 3: When quantitative unloading is required, according to the gravity of the support platform 3 and the amount of raw materials used, the screw 499 is rotated clockwise or counterclockwise. Under the action of the slideway limit, the threaded rotation force of the screw 499 drives the weight 4910 to move to the left or right until the weight scale 498 corresponding to the weight 4910 is equal to the weight of the support platform 3 after quantitative unloading;

[0039] As the raw materials continue to increase, the gravity of the supporting platform 3 gradually increases, and the first piston 44 increases the pressure on the hydraulic oil 43, allowing the second piston 47 to drive the rack 48 to move right, and the gear 493 drives the supporting rod 497 to rotate counterclockwise. When the supporting rod 497 is horizontal, the two contacts 496 contact to form a closed loop, and an electrical signal is fed back to the controller 6, and the solenoid valve 8 is closed to achieve quantitative unloading.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
