Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, and in particular to a rice processing device that allows for convenient control of flow rate. Background Technology

[0002] Precise control of the rice feed rate is a key factor in ensuring processing quality and efficiency during rice processing.

[0003] Existing rice processing equipment has many shortcomings in controlling the feed flow rate. For example, some equipment uses simple valves to control the feed, which have low adjustment accuracy and are difficult to flexibly adjust the flow rate according to actual processing needs. Although some electrically controlled valves can easily adjust the flow rate, it is not convenient to manually open and close the valve when the drive mechanism fails. Some equipment cannot effectively prevent rice from accumulating and clumping in the storage bin, resulting in uneven feeding and affecting the stability of subsequent processing steps and product quality. Therefore, we propose a rice processing device with convenient flow rate control to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rice processing device that allows for convenient flow rate control. Through a dual electric and manual control structure, combined with technologies such as gear and rack transmission, laser ranging feedback, stirring to prevent accumulation, and intelligent control, it achieves precise adjustment of the feed flow rate, stable equipment operation, and emergency handling of malfunctions, effectively improving the efficiency and quality of rice processing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rice processing device for convenient flow rate control, comprising a storage bin, a feeding pipe fixedly installed at the bottom of the storage bin, two rotating shafts rotatably installed on the front and rear inner walls of the feeding pipe, an adjusting plate fixedly installed on the rotating shaft, the two adjusting plates being adapted to the feeding pipe; a housing fixedly installed on the front side of the feeding pipe, a lifting plate slidably installed inside the housing, a drive seat fixedly installed at the bottom of the lifting plate, a moving hole opened on one side of the drive seat, a moving seat slidably installed in the moving hole, two rectangular seats fixedly installed at the bottom of the moving seat, and a drive mechanism provided between the rectangular seats and the rotating shaft.

[0006] By adopting the above technical solutions, and through a dual electric and manual control structure, combined with technologies such as gear and rack transmission, laser ranging feedback, stirring to prevent accumulation, and intelligent control, the system can achieve precise adjustment of the feed flow rate, stable equipment operation, and emergency handling of faults, effectively improving the efficiency and quality of rice processing.

[0007] A further feature of this invention is that the drive mechanism includes a rack and a rotating gear. A rack is fixedly installed on one side of each of the two rectangular seats that are far apart from each other. The front end of the rotating shaft extends to the front side of the feed tube and is fixedly installed with a rotating gear, and the rotating gear meshes with the rack.

[0008] By adopting the above technical solution, the linear motion is converted into rotational motion through the meshing transmission of the rack and pinion and the rotating gear, so that the two adjusting plates can rotate synchronously and symmetrically, ensuring precise control of the opening size of the feed pipe, smooth transmission and high precision, and effectively improving the accuracy of flow rate adjustment.

[0009] A further feature of this invention is that an electric push rod is fixedly installed on the top of the housing, and the output shaft of the electric push rod is fixedly connected to the lifting plate. A laser rangefinder is fixedly installed on the inner wall of the top of the housing, and the laser rangefinder is located directly above the lifting plate. Two limiting seats are fixedly installed on one side of the housing, and the lifting plate is located between the two limiting seats.

[0010] By adopting the above technical solutions, the electric push rod provides a stable driving force to ensure the smooth movement of the lifting plate; the laser rangefinder monitors the position of the lifting plate in real time, forming a closed-loop control system to provide data feedback for precise adjustment of the flow rate; and the limit seat restricts the range of motion of the lifting plate to prevent it from deviating or shaking, thus ensuring the stability and reliability of the entire transmission system.

[0011] A further feature of this invention is that a threaded hole is provided on the bottom inner wall of the movable hole, a drive screw is installed in the threaded hole, the top end of the drive screw is rotatably mounted on the bottom of the movable seat, and the bottom end of the drive screw extends to the bottom of the drive seat and is fixedly mounted with a handwheel.

[0012] By adopting the above technical solution and utilizing the principle of threaded transmission, the handwheel can be turned to precisely control the lifting and lowering of the drive screw, thereby driving the moving seat and rectangular seat to move, realizing fine adjustment of the angle of the adjustment plate. It provides a reliable backup adjustment method when the electric push rod fails or manual operation is required, enhancing the adaptability and practicality of the device.

[0016] By adopting the above technical solution, the drive motor drives the stirring rod to rotate, which fully agitates the rice in the storage bin, destroys the static friction and accumulation structure between the rice grains, effectively prevents rice from clumping and bridging, and ensures that the rice can flow into the feed pipe evenly and continuously, providing a basic guarantee for stable flow rate control.

[0017] The present invention is further configured such that: two guide holes are provided at the bottom of the housing, and the rectangular seat and the straight rack pass through the corresponding guide holes; a connecting hole is provided at the bottom of the housing, and the drive seat is slidably connected to the connecting hole; a controller is fixedly installed on the front side of the housing, and the pressure sensor and the electric push rod are both electrically connected to the controller.

[0018] By adopting the above technical solution, the guide hole and the connecting hole provide precise guidance for each moving part, reduce motion resistance and wear, and ensure transmission accuracy; the controller, combined with the data feedback from the pressure sensor, can automatically adjust the stroke of the electric push rod according to the actual material feeding requirements, realize intelligent control of the flow rate, and improve the automation level and processing efficiency of the device.

[0019] The beneficial effects of this utility model are:

[0020] (1) Precise flow rate control: The electric push rod is activated by the controller, which drives the lifting plate to move downward. Then, through the drive seat, moving seat, rectangular seat, straight rack and rotating gear, the adjusting plate is rotated to adjust the size of the discharge pipe opening, thereby precisely controlling the discharge flow rate of rice to meet the requirements of different processing steps for rice flow rate.

[0021] (2) Anti-accumulation function: The drive motor drives the stirring shaft and stirring rod to rotate, which stirs the rice in the storage bin, effectively preventing the rice from accumulating and clumping, ensuring that the rice can flow out of the feed pipe evenly and stably, and improving the processing quality and efficiency.

[0022] (3) Dual control guarantee: When the electric push rod fails, the handwheel can be turned manually to drive the moving seat and other components to move, thereby controlling the rotation of the adjustment plate. This ensures that the device can still work normally in case of failure, improving the reliability and practicality of the device. Attached Figure Description
