Description

Technical Field

[0001] This utility model relates to the field of germ rice processing technology, specifically to a germ rice processing and impurity removal device. Background Technology

[0002] Germinated rice is rice that retains the germ portion of the grain, while the rest is exactly the same as white rice. In fact, the most important central part of rice is the germ, and germinated rice is rice with a germ retention rate of over 80%.

[0003] A search revealed Chinese Patent Publication No. CN 210230603U, which discloses a purification device for rice processing. The device includes a support frame and a purification frame. Universal wheels are bolted to the four corners of the support's bottom. A spring is welded to the upper end of the support, and the purification frame is mounted on the upper end of the spring. A vibration motor is mounted on one side wall of the purification frame. The advantages are: the transparent cover design effectively prevents rice from splashing and dust from spreading during purification, reducing rice loss and creating a cleaner purification environment. The design of the movable screen, pull-out groove, limiting bolts, limiting slots, and screw holes allows the opening size of the purification components to be adjusted according to the actual size of the rice, increasing the device's applicability and making it more practical.

[0004] In the process of removing impurities, germ rice is placed on a vibrating screen. However, germ rice is usually placed in the same position, which will form a thicker local accumulation of material on the screen surface, while the material in the surrounding area is thinner. The thicker material layer will hinder the contact between the lower germ rice and the screen surface, so that some germ rice cannot fully participate in the screening process, resulting in incomplete removal of impurities. Therefore, it is necessary to provide a germ rice impurity removal device that can evenly distribute germ rice on the vibrating screen to improve the quality of impurity removal. Utility Model Content

[0005] The purpose of this utility model is to provide a germ rice processing and impurity removal device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a device for removing impurities during germ rice processing, comprising:

[0007] Vibrating screen;

[0008] The uniformizing component includes a fixed plate, a motor, a lead screw, and a movable plate. The fixed plate is fixed to both sides of the upper end of the vibrating screen, the motor is fixed to one side of the fixed plate, the lead screw is fixed to the output end of the motor, and the lead screw rotates through the two fixed plates. The movable plate is threaded through the outer surface of the lead screw.

[0009] Furthermore, a storage bin is fixed to the rear end of the vibrating screen, and a discharge pipe is connected to one side of the storage bin.

[0010] Furthermore, the movable plate has a mounting hole in its center, and the end of the feed tube extends into the mounting hole.

[0011] Furthermore, two support plates are fixed on the upper surface of the vibrating screen, and a limit rod is fixed in the middle of the support plates, with the movable plate sliding through the limit rod.

[0012] Furthermore, a fixing platform is fixed to the lower surface of the motor, and one side of the fixing platform is fixed to the surface of the fixing plate.

[0013] Furthermore, it also includes a fixing component, which includes a connecting plate, a threaded hole, a threaded rod, and a bearing. The connecting plate is fixed on both sides of the movable plate, the threaded hole is opened in the center of the connecting plate, the threaded rod is threaded through the threaded hole, and the bearing is rotatably mounted on one end of the threaded rod.

[0014] Furthermore, a clamping block is fixed on one side of the bearing. There are two clamping blocks, and the two clamping blocks are in contact with the feed pipe. Limiting posts are fixed on both sides of the connecting plate, and the two ends of the clamping blocks slide through the limiting posts.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes a vibrating screen, a storage bin, a feeding pipe, and a uniform distribution component. When removing impurities from germ rice, the feeding pipe is simply placed in the mounting hole. An external controller then starts the motor, which drives a lead screw to rotate. The lead screw rotation synchronously drives a movable plate to move horizontally. Limited by a limit rod, the movable plate moves smoothly horizontally, simultaneously moving the feeding pipe horizontally across the vibrating screen surface. This ensures uniform feeding of the germ rice, preventing excessive accumulation on the screen surface due to a fixed feeding point. It also prevents overly thick material in certain areas, which could affect the screening effect. This ensures full utilization of the entire screen surface, improving screening efficiency and the consistency of impurity removal. The germ rice is now evenly distributed on the vibrating screen, enhancing impurity removal efficiency and ensuring processing quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a germ rice processing and impurity removal device, comprising:

[0029] Vibrating screen 11, with a storage bin 12 fixed at the rear end of the vibrating screen 11, and a discharge pipe 13 connected to one side of the storage bin 12;

[0030] The uniform assembly includes a fixed plate 21, a motor 22, a lead screw 23, and a movable plate 24. The fixed plate 21 is fixed on both sides of the upper end of the vibrating screen 11. The motor 22 is fixed on one side of the fixed plate 21. The lead screw 23 is fixed at the output end of the motor 22 and rotates through the two fixed plates 21. The movable plate 24 is threaded through the outer surface of the lead screw 23.

[0031] The vibrating screen 11 is the core component for removing impurities from germ rice. It generates screening force through its own vibration. The storage hopper 12 is used to temporarily store the germ rice after it has been screened by the vibrating screen 11. The fixing plate 21 serves to fix and support the entire homogenizing assembly, providing a stable installation foundation for components such as the motor 22 and the lead screw 23. The motor 22 serves as a power source, providing power for the operation of the homogenizing assembly. The lead screw 23 converts the rotational motion of the motor into linear motion.

[0032] The movable plate 24 has a mounting hole 25 in the center, and the end of the feed pipe 13 extends into the mounting hole 25. Two support plates 26 are fixed on the upper surface of the vibrating screen 11. A limit rod 27 is fixed in the middle of the support plate 26, and the movable plate 24 slides through the limit rod 27. A fixed platform 221 is fixed on the lower surface of the motor 22, and one side of the fixed platform 221 is fixed to the surface of the fixed plate 21.

[0033] The movable plate 24 is used to install and fix the feed pipe 13 and drive the feed pipe 13 to move horizontally on the surface of the vibrating screen 11. The support plate 26 is fixed on the upper surface of the vibrating screen 11. The middle limiting rod 27 provides limiting and guiding function for the movement of the movable plate 24. The fixed table 221 is used to enhance the stability and installation accuracy of the motor 22.

[0034] Working principle:

[0035] When removing impurities from germ rice, simply place the feed pipe 13 into the mounting hole 25, then start the motor 22 via the external controller. The motor 22 drives the lead screw 23 to rotate, and the rotation of the lead screw 23 synchronously drives the movable plate 24 to move horizontally. Under the limit of the limit rod 27, the movable plate 24 moves horizontally smoothly. The movable plate 24 synchronously drives the feed pipe 13 to move horizontally on the surface of the vibrating screen 11, so that the feed pipe 13 feeds the material evenly, avoiding the accumulation of germ rice on the surface of the vibrating screen 11. This avoids excessive accumulation of germ rice in local areas due to fixed feed points, and prevents the material from being too thick in some areas, which would affect the screening effect.

[0036] This step ensures that the entire screen surface is fully utilized, improving the consistency of screening efficiency and impurity removal effect. The germ rice is now evenly distributed on the vibrating screen 11, enhancing the impurity removal effect and efficiency, and ensuring processing quality.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The fixing assembly includes a connecting plate 31, a threaded hole 32, a threaded rod 33, and a bearing 34. The connecting plate 31 is fixed on both sides of the movable plate 24. The threaded hole 32 is opened in the center of the connecting plate 31. The threaded rod 33 is threaded through the threaded hole 32. The bearing 34 is rotatably mounted on one end of the threaded rod 33. A clamping block 35 is fixed on one side of the bearing 34. Two clamping blocks 35 are provided. The two clamping blocks 35 are in contact with the feed tube 13. Limiting posts 36 are fixed on both sides of the connecting plate 31, and the two ends of the clamping blocks 35 slide through the limiting posts 36.

[0039] The connecting plate 31 provides a stable support base and connection platform for the entire fixing assembly. The threaded hole 32 cooperates with the threaded rod 33 to realize the transmission function of converting rotational motion into linear motion. By rotating the threaded rod 33, the movement distance of the clamping block 35 can be precisely controlled, thereby adjusting the distance between the two clamping blocks 35 to fix the feed tubes 13 of different diameters.

[0040] Working principle:

[0041] After the feed tube 13 is placed into the mounting hole 25, the threaded rod 33 is rotated. With the connection of the threaded hole 32, the threaded rod 33 moves horizontally in the threaded hole 32. At the same time, with the connection of the bearing 34, the threaded rod 33 only drives the clamping block 35 to move horizontally until the clamping block 35 fixes the feed tube 13 inside the mounting hole 25, ensuring the stability of the feed tube 13.

[0042] This step ensures the reliability and stability of the feeding tube 13 during the uniform feeding process, so that the feeding position is always accurate.
