Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a feeding device for rice processing. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. The cleaning process involves using suitable equipment, appropriate technological procedures, and proper operating methods to remove various impurities mixed in with the paddy, thereby improving the quality of the finished rice. The paddy needs to be fed into the threshing machine using a feeding device.

[0003] A search revealed Chinese Patent Publication No. CN212608245U, which discloses a feeding device for rice processing, belonging to the field of rice processing. The feeding device includes a housing, with a feeding funnel connected to the top of the housing. A feeding port is located on the right side of the housing, and an inclined feeding cylinder is fixedly installed on the right side of the feeding port. A top plate is fixedly installed at the end of the feeding cylinder furthest from the housing. A feeding motor drives a rotating rod to rotate, which in turn drives a conveying auger to rotate. Rice is conveyed by the rotation of the conveying auger through a screw conveyor, similar in principle to a screw conveyor.

[0004] Existing technologies similar to the aforementioned feeding devices rely on the rotation of a conveying auger for spiral conveying. When the material depth on the support plate is shallow, the rotation of the conveying auger makes it difficult to achieve spiral conveying, which can easily lead to material accumulation. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a feeding device for rice processing. Its advantage lies in improving the smoothness of feeding and preventing raw material blockage and accumulation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding device for rice processing includes a movable base, a feeding trough is provided on one side of the top of the movable base, and a screw conveyor assembly is provided on the other side of the top of the movable base. The screw conveyor assembly and the feeding trough are connected by a conveying hose.

[0008] An electric push rod is provided on the bottom inner wall of the feeding trough. One end of the piston rod of the electric push rod is hinged to a guide plate. One end of the guide plate is hinged to the bottom of the feeding trough. The top of the guide plate has an arc surface structure, and the lower end of the guide plate faces the conveying hose.

[0009] A material distribution component is provided at the opening of the feeding trough, and the material distribution component is fixed to the inner wall of the feeding trough.

[0010] The above technical solution works as follows: During use, rice is continuously added to the feeding trough using the feeding component. When there is a lot of rice in the feeding trough, the rice is transported by gravity along the inclined surface of the guide plate through the conveying hose to the screw conveyor component. The screw conveyor component transports the rice to the thresher at a designated height for threshing. When there is less rice in the feeding trough, the piston rod of the electric push rod is extended, and the guide plate will have a greater inclination. The rice can more easily enter the screw conveyor component along the guide plate, improving the smoothness of feeding and avoiding the occurrence of raw material blockage and accumulation.

[0011] The present invention is further configured such that the spiral conveying assembly includes a conveying cylinder hinged to the top of the movable seat, an electric motor is provided at the top of the conveying cylinder, the output shaft of the electric motor is connected to a conveying auger, a feeding pipe is provided at the bottom of the conveying cylinder near the end of the electric motor, and the conveying cylinder and the movable seat are connected by a hydraulic cylinder.

[0012] The above technical solutions allow for adjusting the tilt of the conveying cylinder by controlling the extension or shortening of the hydraulic cylinder piston rod, making it suitable for threshers of different heights. During conveying, the control motor drives the conveying auger to rotate, which in turn transports the raw material from the bottom of the conveying cylinder to the feeding pipe for feeding, thus improving the convenience of feeding.

[0013] The present invention is further configured such that the material distribution component includes a material distribution cylinder, a motor is provided on the outer wall of the material distribution cylinder, the output shaft of the motor is connected to a rotating roller, a plurality of equally spaced material distribution plates are provided on the outer wall of the rotating roller, the material distribution plates can slide along the inner wall of the material distribution cylinder, a material leakage port is provided at the bottom of the material distribution cylinder, and a feeding hopper is provided at the top of the material distribution cylinder.

[0014] The above technical solution involves using a feeding hopper to add raw materials into a distributing cylinder, controlling a motor to drive a rotating roller, which in turn drives a distributing plate to rotate. As the distributing plate rotates, the raw materials can enter the feeding trough in batches, avoiding blockage caused by adding too much material at once.

[0015] The present invention is further configured such that the cross-section of the material leakage port is an isosceles trapezoidal structure, and the larger opening of the material leakage port faces upward.

[0016] The above technical solution, with its isosceles trapezoidal cross-section, allows for a larger opening at the material discharge port, improving the smoothness of material discharge.

[0017] The present invention is further provided with a sealing strip at the top of the guide plate, and the sealing strip has a triangular cross-section.

[0018] The above technical solution involves setting a sealing strip to seal the gap between the guide plate and the feeding trough, thus preventing material leakage.

[0019] The present invention is further configured such that the sealing strip is made of rubber.

[0020] Through the above technical solutions, the rubber sealing strip has good elasticity, which further improves the sealing effect.

[0021] The present invention is further provided with a push rod on one side of the movable seat, and the push rod has an S-shaped structure.

[0022] The above technical solution, with its push rod, allows for easy movement of the device, improving its mobility.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. This rice processing feeding device continuously adds paddy rice into the feeding trough using a distributing component. When there is a lot of paddy rice in the feeding trough, the paddy rice is transported by gravity along the inclined surface of the guide plate through the conveying hose to the screw conveyor component. The screw conveyor component transports the paddy rice to the thresher at a designated height for threshing. When there is less paddy rice in the feeding trough, the piston rod of the electric push rod is extended, and the guide plate will have a greater inclination. The paddy rice can more easily enter the screw conveyor component along the guide plate, improving the smoothness of feeding and avoiding the occurrence of raw material blockage and accumulation.

[0025] 2. This rice processing feeding device controls the extension or shortening of the hydraulic cylinder piston rod to adjust the inclination of the conveying cylinder, making it suitable for threshers of different heights. During conveying, the control motor drives the conveying auger to rotate, which in turn transports the raw materials at the bottom of the conveying cylinder to the feeding pipe for feeding, thus improving the convenience of feeding.

[0034] A material distribution component is provided at the opening of the feeding trough 2, and the material distribution component is fixed to the inner wall of the feeding trough 2.

[0035] In this embodiment, the screw conveyor assembly includes a conveying cylinder 6 hinged to the top of the movable seat 1. A motor 7 is installed on the top of the conveying cylinder 6, and the output shaft of the motor 7 is connected to a conveying auger 8. A feeding pipe 9 is installed at the bottom of the conveying cylinder 6 near the motor 7. The conveying cylinder 6 and the movable seat 1 are connected by a hydraulic cylinder 10. By controlling the extension or shortening of the piston rod of the hydraulic cylinder 10, the inclination of the conveying cylinder 6 can be adjusted, making it suitable for threshers of different heights. During conveying, the motor 7 is controlled to drive the conveying auger 8 to rotate. The rotation of the conveying auger 8 transports the raw material at the bottom of the conveying cylinder 6 to the feeding pipe 9 for feeding, improving the convenience of feeding.

[0036] The material dispensing assembly includes a dispensing cylinder 11, with a motor 12 mounted on its outer wall. The output shaft of the motor 12 is connected to a rotating roller. Multiple equally spaced dispensing plates 13 are mounted on the outer wall of the rotating roller, and these plates 13 can slide along the inner wall of the dispensing cylinder 11. A discharge port 14 is located at the bottom of the dispensing cylinder 11, and a feeding hopper 15 is located at the top. Raw materials are added to the dispensing cylinder 11 using the feeding hopper 15. The motor 12 is controlled to rotate the rotating roller, which in turn rotates the dispensing plates 13. The rotation of the dispensing plates 13 allows the raw materials to enter the feeding trough 2 in batches, preventing blockage caused by excessive material added at once.

[0037] Furthermore, the cross-section of the discharge port 14 is an isosceles trapezoidal structure, with the larger opening of the discharge port 14 facing upwards.

The screw conveyor assembly transports the rice to the thresher at a specified height for threshing. When there is less rice in the feeding trough 2, the piston rod of the electric push rod 4 is extended, and the guide plate 5 will have a greater inclination. The rice can more easily enter the screw conveyor assembly along the guide plate 5, which improves the smoothness of feeding and avoids the occurrence of raw material blockage and accumulation.
