They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figures 1 to 7 As shown, the present invention includes a hopper assembly 1, a transmission assembly 2, and a feeding box assembly 3. The hopper assembly 1 is based on a hopper 101. The bottom outlet of the hopper 101 is connected to a silicone flexible connector 104 via a clamp 102 and a quick-connect connector 103. The silicone flexible connector 104 is connected to the receiving port 305 at the top of the feeding box assembly 3 via a transparent connecting pipe 105. Transmission assembly 2 includes a transmission bearing housing 201 connected to an external frame. A connecting shaft 202 is rotatably mounted on the transmission bearing housing 201. The top of the connecting shaft 202 is connected to an external drive motor, and the bottom is connected to a transmission shaft 204. The bottom of the transmission shaft 204 is connected to the feeding box assembly 3 through a bushing 205 and a coupling 206. The feeding box assembly 3 is mainly composed of a filling disc 304 with openings at both the top and bottom. A filling disc cover plate 303 is provided on the top of the filling disc 304, and a transmission box 302 is provided on the top of the filling disc cover plate 303. A box cover plate 301 is provided on the top of the transmission box 302. The box cover plate 301 is connected to the hopper 101, and the bottom outlet of the hopper 101 is connected to the receiving port 305 provided at the bottom of the transmission box 302. Inside the transmission box 302, eight sequentially meshing gears are arranged in a U-shape and rotate. The transmission gears 306 are connected, and the transmission gears 306 at both ends are respectively provided with a first feeding shaft 307 and a second feeding shaft 309. The first feeding shaft 307 and the second feeding shaft 309 extend into the feeding disc 304 and are connected to the feeding paddle 308. The second feeding shaft 309 is connected to the coupling 206 for transmission. The transmission ratio between each transmission gear 306 is 1:1, which ensures that the rotation speed of the first feeding shaft 307 and the second feeding shaft 309 is the same as the motor speed.

[0016] When this utility model is in operation, the connecting shaft 202 is powered by a motor to rotate. The connecting shaft 202 drives the transmission shaft 204 to rotate, which in turn drives the second feeding shaft 309 to rotate through the coupling 206. The second feeding shaft 309 drives the feeding paddle 308 and the transmission gear 306 to rotate. In turn, the transmission gears 306 drive the first feeding shaft 307 and the feeding paddle 308 connected to it to rotate in the opposite direction to realize the feeding action. The two feeding paddles 308 are in a gear-like meshing state and are distributed vertically to avoid interference. They can feed alternately, making feeding more uniform and stable, and enabling the material to be transported. After feeding is completed, waste can be discharged through the waste outlet under the stuffing disc 304 to reduce material accumulation.

[0017] Preferably, a material level sensor 106 is installed on the hopper 101 to monitor the material level in the hopper 101 in real time.

[0018] Preferably, the coupling 206 and the second feed shaft 309 are connected by a slot for easy assembly and disassembly.

[0019] Preferably, a universal joint 203 is provided between the connecting shaft 202 and the drive shaft 204, so that the drive shaft 204 can be moved without affecting the installation and maintenance of the feeding box assembly 3.
