DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a rice uniform feeding device, including a conveyor 1, an inlet 102 is fixedly connected above the conveyor 1, a discharge port 101 is fixedly connected below the conveyor 1, a transmission shaft 201 is rotatably installed in the conveyor 1, and a plurality of dividing blades 202 are fixedly connected to the transmission shaft 201. A hopper 5 is slidably installed in the inlet 102. Limiting chutes 4 are provided on both sides of the inlet 102. L-shaped limiting sliders 501 are symmetrically fixedly connected to the hopper 5, and the L-shaped limiting sliders 501 are slidably matched with the limiting chutes 4.

[0022] In this implementation scheme, the lower end of the hopper 5 is inserted into the interior of the inlet 102, and the L-shaped limiting slider 501 is slidably matched with the limiting chute 4, restricting the hopper 5 to move only up and down. At the same time, the length of the limiting chute 4 is limited, which will further limit the up and down movement stroke of the hopper 5, thereby preventing the lower end of the hopper 5 from disengaging from the interior of the inlet 102. At the same time, when the hopper 5 moves up and down, it will generate a certain vibration, which will assist the rice inside the hopper 5 to slide downwards, avoiding the accumulation and blockage of rice inside the hopper 5. The transmission shaft 201 and the dividing blades 202 cooperate with each other. When the rice enters the interior of the conveyor 1 from the inlet 102, it will fill the space between the two dividing blades 202. After the transmission shaft 201 drives the dividing blades 202 to rotate, it will drive the rice between the dividing blades 202 to move. When the rice moves to the discharge port 101, it will be discharged from the discharge port 101 by gravity. By controlling the rotation speed of the transmission shaft 201, the feeding speed of the rice can be controlled, thereby achieving the purpose of uniform feeding.

[0023] Among them, in order to achieve the purpose of uniform feeding, the following technical solution is adopted for this device: a fixed foot 103 is fixedly connected to the back of the conveyor 1, a motor bracket 104 is fixedly connected to the front of the conveyor 1, a vibration motor 3 is fixedly connected to the motor bracket 104, a power motor 2 is fixedly connected to the front of the conveyor 1, and the output end of the power motor 2 is fixedly connected to the transmission shaft 201.

[0024] By starting the power motor 2, the transmission shaft 201 can be driven to rotate. When the transmission shaft 201 rotates, the dividing blades 202 can be driven to rotate, thereby uniformly conveying the rice. The fixed foot 103 can cooperate with bolts to fix the device on the rice processing equipment.

[0025] Among them, in order to achieve the purpose of vibrating the hopper 5, the following technical solution is adopted in this device: A rotating disk 301 is fixedly connected to the output end of the vibration motor 3. An eccentric shaft 302 is rotatably installed at a position near the edge behind the rotating disk 301. A connecting rod 401 is fixedly connected inside the limit chute 4. A return spring 402 is sleeved on the connecting rod 401. A U-shaped connecting frame 502 is fixedly connected between two L-shaped limit sliders 501. The L-shaped limit slider 501 cooperates with the eccentric shaft 302. An avoidance hole 503 is opened below the L-shaped limit slider 501.

[0026] By starting the vibration motor 3, the rotating disk 301 can be driven to rotate. The rotation of the rotating disk 301 will drive the eccentric shaft 302 to perform eccentric rotation. The eccentric shaft 302 cooperates with the U-shaped connecting frame 502. When the eccentric shaft 302 performs eccentric rotation, the eccentric shaft 302 will contact the U-shaped connecting frame 502, thereby pushing the U-shaped connecting frame 502 to move upward. The upward movement of the U-shaped connecting frame 502 will drive the hopper 5 to move upward, so that the hopper 5 makes an upward movement. When the eccentric shaft 302 rotates to the apex, the height of the eccentric shaft 302 will move downward. At this time, the U-shaped connecting frame 502 loses the support of the eccentric shaft 302. The hopper 5 will move downward with the eccentric shaft 302 due to its own weight and the weight of the rice inside. The return spring 402 will provide a certain buffer for the L-shaped limit slider 501 to avoid the L-shaped limit slider 501 hitting the inside of the limit chute 4 due to the too fast downward movement speed of the hopper 5. At the same time, the return spring 402 absorbs energy and will be released as elastic force, so that the hopper 5 makes a short-distance reciprocating movement up and down, further making the hopper 5 in a vibrating state. The connecting rod 401 is used to limit the return spring 402 to prevent the return spring 402 from bending and deforming. The avoidance hole 503 cooperates with the connecting rod 401 to avoid interference between the connecting rod 401 and the L-shaped limit slider 501.

[0027] The working principle and usage process of the present utility model: When in use, the device needs to be fixed on the processing equipment by using the fixing feet 103. Pour the rice into the hopper 5. Start the power motor 2 and the vibration motor 3. The power motor 2 will drive the transmission shaft 201 to rotate. The rotation of the transmission shaft 201 will drive the dividing blade 202 to rotate. The rotation of the dividing blade 202 will drive the rice entering between the two dividing blades 202 to rotate. When the rice moves to the blanking port 101, it will be discharged from the blanking port 101 by gravity, so that the rice is evenly discharged from the blanking port 101. The vibration motor 3 will drive the eccentric shaft 302 to perform eccentric rotation. The eccentric shaft 302 cooperates with the U-shaped connecting frame 502, which will drive the hopper 5 to make a reciprocating movement up and down, generating a certain vibration, thereby assisting the rice inside the hopper 5 to slide downward and preventing the rice inside the hopper 5 from accumulating and blocking.

[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
