Description

Technical Field

[0001] This utility model relates to the field of rice processing, specifically a high-efficiency rice color sorter. Background Technology

[0002] In the rice processing industry, color sorting is one of the core steps to ensure the final quality of rice. Its main purpose is to accurately remove discolored grains (such as yellow rice, black rice, etc.), imperfect grains (such as broken rice, insect-damaged grains, etc.), and various impurities (such as stones, rice husks, etc.) from the rice, thereby improving the overall quality and market value of the rice.

[0003] Traditional rice color sorters often use a simple, fixed-flow feeding device, which cannot flexibly adjust the feeding amount according to the quality differences of different batches of rice or the production speed requirements. This leads to two problems in actual production: either too much rice is fed, causing a large amount of rice to accumulate on the guide plate, making it impossible for the color sorter to fully and accurately identify and screen each grain of rice, reducing the color sorting accuracy and causing some discolored grains and impurities to mix into qualified rice; or too little rice is fed, causing the equipment to frequently be idle and waiting, significantly reducing production efficiency and increasing the processing cost per unit of rice.

[0004] Therefore, it is essential to develop a new type of high-efficiency rice color sorter. Utility Model Content

[0005] This invention provides a high-efficiency rice color sorter to solve the problem that the fixed and unadjustable feeding amount of traditional rice color sorters leads to poor rice color sorting accuracy and low sorting efficiency.

[0006] This utility model solves the above-mentioned technical problems through the following technical solution: a high-efficiency rice color sorter, including a base plate and a bracket fixedly installed at both ends of the base plate. A feeding component is fixedly installed on the upper end of the bracket, and a guide plate is inclinedly installed below the feeding component. The guide plate is supported by a rice bin, and the end of the rice bin is fixedly connected to the bracket. Color sorters are symmetrically installed on both sides of the lower end of the guide plate with the guide plate as the reference.

[0007] Furthermore, the feeding assembly includes a light-transmitting plate fixedly installed on the upper end of the bracket, a mounting frame fixedly installed on the upper end of the light-transmitting plate, hoppers arranged linearly on the mounting frame, a feeding unit rotatably installed inside the hoppers, and an adjustment unit installed inside the feeding unit.

[0008] Furthermore, a discharge plate is provided below the hopper, with both ends of the discharge plate fixedly connected to the mounting frame, and a spotlight is installed at the lower end of the discharge plate corresponding to the position of the guide plate.

[0009] Furthermore, the feeding unit includes a hollow horizontal shaft that runs through multiple hoppers. Hollow rollers are fixedly installed on the hollow horizontal shaft at positions corresponding to the inside of the hoppers. Several material troughs are evenly arranged on the outer side of the hollow rollers along their circumference.

[0010] Furthermore, the outer wall of the hollow roller and the inner wall of the hopper are in sliding contact.

[0011] Furthermore, the adjustment unit includes an adjustment shaft coaxially mounted inside the hollow horizontal shaft, and a flower-shaped cam is fixedly mounted on the adjustment shaft at a position corresponding to the inside of the hollow roller.

[0012] Furthermore, an elastic air bladder membrane is fixedly installed at the bottom of the material trough, and a slide rod is fixedly connected to the inner wall of the elastic air bladder membrane. The slide rod extends into the hollow roller and is fixedly connected to a hemisphere. A return spring is sleeved on the slide rod between the hemisphere and the hollow roller.

[0013] Furthermore, the flower-shaped cam protrusion and the hemispherical arc surface slide together.

[0014] Furthermore, a first limiting disc is fixedly connected to one end of the hollow horizontal shaft, and a second limiting disc is fixedly connected to the corresponding end of the adjusting shaft. The first limiting disc and the second limiting disc are detachably connected by a pin, and an arc-shaped handle is fixedly installed on the side wall of the second limiting disc.

[0015] Furthermore, a No. 1 collection box is provided at the upper end of the support corresponding to the position below the guide plate, and a No. 2 collection box is provided on the side of the No. 1 collection box.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] 1. The feeding unit, through the design of hollow rollers and troughs, can evenly convey rice to the guide plate according to a certain rhythm and pattern, avoiding the problem of inaccurate color sorting caused by uneven feeding, and improving the accuracy and stability of color sorting. The setting of the adjustment unit allows the operator to flexibly adjust the feeding amount according to actual production needs, such as rice quality and production speed. By rotating the adjustment shaft to change the relative position of the flower-shaped cam and the hemisphere, the volume of the trough can be changed, achieving precise control of the feeding amount, improving the adaptability and production efficiency of the equipment.

[0019] 2. The color sorter has a reasonable overall structure design, with relatively few parts and a compact layout. Compared with traditional complex color sorters, it is easier for operators to master the operation of the equipment, and maintenance personnel can quickly locate the fault point and carry out repairs, which greatly shortens the equipment maintenance time, reduces maintenance costs, and improves the continuity of the production process.

In this embodiment, the end of the hollow horizontal shaft 341 is fixedly connected to the output shaft of the existing drive equipment, and the hollow horizontal shaft 341 can be driven to rotate by the existing drive equipment.

[0038] The outer wall of the hollow roller 342 and the inner wall of the hopper 33 are in sliding contact.

[0039] The adjustment unit 35 includes an adjustment shaft 351 coaxially mounted inside the hollow horizontal shaft 341, and a flower-shaped cam 352 fixedly mounted on the adjustment shaft 351 at a position corresponding to the inside of the hollow roller 342.

[0040] An elastic airbag membrane 353 is fixedly installed at the bottom of the material trough 343. A slide rod 354 is fixedly connected to the inner wall of the elastic airbag membrane 353. The slide rod 354 extends into the hollow roller 342 and is fixedly connected to a hemisphere 355. A return spring 356 is sleeved on the slide rod 354 between the hemisphere 355 and the hollow roller 342.

[0041] The flower-shaped cam 352 protrusion and the hemispherical 355 arc surface slide together.

[0042] The hollow horizontal shaft 341 is fixedly connected to one end of a first limiting plate 38, and the corresponding end of the adjusting shaft 351 is fixedly connected to a second limiting plate 39. The first limiting plate 38 and the second limiting plate 39 are detachably connected by a pin 310. An arc-shaped handle 311 is fixedly installed on the side wall of the second limiting plate 39.

[0043] A first collection box 7 is provided at the upper end of the support 2, corresponding to the position below the guide plate 4, and a second collection box 8 is provided on the side of the first collection box 7.

[0044] Working principle:

[0045] The rice to be sorted in the rice bin 5 is poured into the hopper 33 of the feeding component 3. At this time, the feeding unit 34 is in the initial state, and the opening of the trough 343 of the hollow roller 342 is facing upward, ready to scoop up the rice.

[0046] The drive unit is activated, causing the hollow horizontal shaft 341 to rotate, which in turn drives the hollow roller 342 to rotate. When rice enters the feed trough 343 and the upper feed trough 343 rotates to the lower position, the rice in the feed trough 343 will fall downwards onto the discharge plate 36, and then fall downwards onto the guide plate 4 and continue to slide down along the guide plate 4. The spotlight 37 can provide sufficient illumination for the falling rice to ensure color sorting accuracy. The color sorter 6 is equipped with a color acquisition sensor and a high-pressure spray nozzle. As the rice grains slide down the guide plate 4, they pass between the color sorters 6 symmetrically arranged on both sides of the lower end. The color sorters 6 use optical principles to quickly scan and identify each grain of rice. By analyzing the reflection and absorption characteristics of rice to specific wavelengths of light, the color sorters 6 can accurately determine whether the rice is a discolored grain, an imperfect grain, or an impurity. Based on the identification results of the color sorters 6, the control system inside the color sorters 6 will control the corresponding high-pressure nozzles to blow the unqualified rice into the second collection box 8, while the qualified rice falls down into the first collection box 7.

[0047] During the actual sorting process, operators can adjust the rice feeding amount according to the rice quality and production needs. Specifically, to adjust the rice, first pause the drive equipment, then remove the pin 310, and then manually rotate the arc-shaped handle 311 to rotate the adjusting shaft 351 and the flower-shaped cam 352. When the protrusion of the flower-shaped cam 352 contacts the arc-shaped surface of the hemisphere 355, it will push the hemisphere 355 away from the flower-shaped cam 352, thereby causing the slide rod 354 to compress the return spring 356, thus activating the elastic airbag. When the membrane 353 deforms, the volume of the feed trough 343 decreases, the amount of rice scooped each time decreases, and the feeding amount decreases. Conversely, when the protrusion of the flower-shaped cam 352 moves away from the hemisphere 355, the elastic air bladder membrane 353 returns to its original shape under the action of the return spring 356, the volume of the feed trough 343 increases, and the feeding amount increases. In this way, the feeding amount can be flexibly adjusted. After each adjustment, the hollow horizontal shaft 341 and the adjusting shaft 351 can be fixed together by the pin shaft 310 to continue the rice color sorting operation.
