Description

Technical Field

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

[0002] In the rice processing process, the rice polishing machine is one of the important pieces of equipment. It can remove the bran powder from the surface of the rice, improving its appearance and eating quality. The feeding device, as a crucial component of the rice polishing machine, directly affects the polishing effect and efficiency.

[0003] Existing rice polishing machine feeding devices often suffer from problems such as difficulty in accurately controlling the feed flow rate and uneven distribution of rice on the conveyor belt during the rice feeding process. Unstable feed flow rate leads to uneven workload of the polishing machine, affecting polishing quality and equipment lifespan; uneven rice distribution results in inconsistent polishing effects and reduces the yield of finished rice. Therefore, we propose a feeding device for rice polishing machines to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a rice polishing machine. By adjusting the screw linkage adjustment disc and the flat plate, the feeding flow rate and the flat plate height are matched. At the same time, the drive motor drives the conveyor belt to transport rice and spread it evenly by the flat plate, thereby improving the feeding accuracy, polishing effect, and the practicality and intelligence of the device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a rice polishing machine, comprising a feeding shell connected to the polishing machine, a feeding hopper above the feeding shell, a feeding pipe installed at the bottom of the feeding hopper, and the feeding pipe being connected to the feeding shell. Two rotating shafts are rotatably mounted on the inner walls of the front and rear sides of the feeding shell. Rotating rollers are fixedly mounted on the rotating shafts, and the same conveyor belt for feeding rice is driven and sleeved on the two rotating rollers. The feeding pipe is equipped with a flow rate adjustment mechanism. A housing is fixedly installed on the top of the feeding shell, and a lifting plate is slidably installed inside the housing. A flat plate for conveying and spreading rice is fixedly installed at the bottom of the lifting plate.

[0006] By adopting the above technical solution, the feed flow rate and the leveling height are matched by adjusting the screw linkage adjustment plate and the leveling plate. At the same time, the drive motor drives the conveyor belt to transport rice and spread it evenly by the leveling plate, which improves the feeding accuracy, polishing effect and the practicality and intelligence of the device.

[0007] A further feature of this invention is that a drive motor is fixedly installed on the front side of the feeding shell, and the output shaft of the drive motor is fixedly connected to the corresponding rotating shaft. By adopting the above technical solution, the drive motor can provide a stable power source for the rotating shaft, thereby driving the rotating roller and conveyor belt to operate continuously, ensuring the continuity and stability of the rice feeding and conveying process, and guaranteeing the normal feeding needs of the polishing machine.

[0008] A further feature of this invention is that the adjusting mechanism includes a rotating shaft and an adjusting disc, the same rotating shaft is rotatably mounted on the inner walls of both sides of the feeding tube, an adjusting disc adapted to the feeding tube is mounted on the rotating shaft, and one end of the rotating shaft extends into the housing. By adopting the above technical solution, the rotating shaft drives the adjusting plate to rotate, which can flexibly change the gap between the adjusting plate and the feeding pipe, so as to achieve precise adjustment of the rice feed flow rate and meet the feeding needs under different production conditions. A further feature of this invention is that a limiting mechanism is provided between the lifting plate and the housing, and a transmission mechanism is provided between the lifting plate and the rotating shaft. The limiting mechanism includes a limiting groove and a limiting slot. Limiting slots are provided on both inner walls of the housing. Limiting seats are fixedly installed on both sides of the lifting plate, and the limiting seats are slidably connected to the corresponding limiting slots. By adopting the above technical solution, the cooperation between the limiting seat and the limiting groove effectively restricts the movement direction of the lifting plate, preventing it from deviating or shaking during the lifting process, ensuring the stability and accuracy of the lifting action of the lifting plate, and thus ensuring the reliability of the flat plate operation. A further feature of this invention is that the transmission mechanism includes a rack seat and a rotating gear, the rotating gear is fixedly mounted on one end of a rotating shaft, the rack seat is fixedly mounted on the bottom of a lifting plate, and the rack seat meshes with the rotating gear. By adopting the above technical solution, when the lifting plate moves, the rack seat drives the rotating gear to rotate, thereby making the rotating shaft rotate synchronously, realizing the linkage between the adjustment mechanism and the lifting plate. While adjusting the feed flow rate, the height of the flat plate is automatically adjusted so that the two match each other, improving the intelligence level and working efficiency of the feeding device. A further feature of this invention is that a guide hole is provided at the top of the housing, and a scale rod is fixedly installed at the top of the lifting plate, with the scale rod passing through the guide hole through the housing. By adopting the above technical solution, the cooperation between the scale rod and the guide hole not only provides guidance for the lifting of the lifting plate, but also allows the position of the lifting plate to be displayed intuitively through the scale, making it convenient for operators to accurately grasp the height of the flat plate, thereby more precisely adjusting the feed flow and flatness. A further feature of this invention is that: a threaded hole is provided on the inner wall of the top of the housing, an adjusting screw is installed in the threaded hole, the bottom end of the adjusting screw is rotatably mounted on the lifting plate, a knob is fixedly installed on the top of the adjusting screw, a rotating groove is provided on the top of the lifting plate, an annular groove is provided on the inner wall of the rotating groove, an annular seat is fixedly installed on the adjusting screw, and the annular seat is rotatably connected to the corresponding annular groove. By adopting the above technical solution, the operator only needs to turn the knob to easily adjust the lifting plate by using the threaded transmission between the adjusting screw and the threaded hole. The operation is simple and convenient. At the same time, the rotating connection between the annular seat and the annular groove ensures that the lifting plate only moves up and down when the adjusting screw is rotated, thus ensuring the smoothness and stability of the adjustment process. A further feature of this invention is that a controller is installed on the front side of the feeding shell, and the drive motor is electrically connected to the controller. By adopting the above technical solution, the controller can intelligently control the drive motor and flexibly adjust the operating parameters of the drive motor, such as the speed, according to actual production needs. This allows for precise control of the conveyor belt's running speed, enabling refined management of the rice feeding amount and improving the automation level and production adaptability of the feeding device.

[0009] The beneficial effects of this utility model are: 1. Flexible adjustment of feed flow rate: By turning the knob, the adjusting screw is rotated, causing the lifting plate to move up and down, which in turn drives the rotating shaft to rotate, which in turn drives the adjusting plate to rotate. The gap between the adjusting plate and the feeding pipe can be precisely adjusted according to actual needs, so as to flexibly adjust the rice feed flow rate and meet the feeding requirements of different polishing operations. 2. Achieve Mechanism Linkage: The transmission mechanism between the adjusting mechanism and the lifting plate enables the linkage function of adjusting the feed flow rate and adjusting the height of the flattening plate. When adjusting the feed flow rate, the height of the flattening plate will automatically adjust accordingly, so that the flattening effect matches the feed flow rate, effectively avoiding the problem of uneven flattening caused by changes in the feed amount, and improving the intelligence level of the feeding device. 3. Ensure polishing effect: During the rice feeding process, the drive motor drives the conveyor belt to transport the rice to the polishing machine. At the same time, the flat plate spreads the rice evenly on the conveyor belt, ensuring that the rice is evenly processed during the polishing process, thereby improving the polishing quality and effect. 4. Convenient and precise operation: Through the design of components such as knobs and adjusting screws, operators can easily adjust the feed flow rate and the height of the flat plate. In addition, the scale bar makes it easy for operators to intuitively understand the position of the lifting plate, achieve precise adjustment, and reduce the difficulty of operation and labor costs.
