Description

Technical Field

[0001] This utility model belongs to the field of color sorting machine technology, and in particular relates to a rice color sorting machine for quantitative discharge. Background Technology

[0002] Rice is a staple food for people in most parts of China. During harvesting, rice inevitably suffers some damage, such as moldy grains, defective grains, and black-headed grains, all of which affect the overall quality of the rice. This is where rice color sorters come in. Rice color sorters utilize photoelectric technology to automatically separate discolored grains from the rice based on differences in its optical properties, thereby improving rice quality and removing impurities.

[0003] However, existing rice color sorters have large internal guide channels, which makes it impossible to control the flow rate of rice during feeding. This can easily cause rice to pile up and flow out, making it impossible for the color sorting equipment to accurately identify moldy rice and thus fail to remove unqualified rice, resulting in poor color sorting effect. Therefore, a rice color sorter with quantitative discharge is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a rice color sorter that can quantitatively discharge rice, thereby solving the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rice color sorter for quantitative discharge, comprising a color sorter body, a feeding frame on the upper surface of the color sorter body, a rotating rod rotatably connected inside the feeding frame, several diverting plates on the circumferential side of the rotating rod, a servo motor on one side of the feeding frame, several guide plates on opposite surfaces of the inner wall of the feeding frame, a through groove on one side of the inner wall of the feeding frame, an intercepting filter screen inside the through groove, a collection box on one side of the feeding frame located on the side of the through groove, symmetrically arranged sliding grooves on the bottom surface of the collection box, a collection box slidably connected between two sets of sliding grooves, a drop groove on the bottom surface of the collection box located between the two sets of sliding grooves, a dust suction fan on one side of the collection box, and symmetrically arranged slots on the upper surface of the collection box, each slot containing a filter element and a filter screen, with mounting plates on the upper surface of the filter element and the filter screen.

[0007] Furthermore, the circumference diameter of the end of the flow divider is adapted to the size of the feed frame, the flow divider is located above the guide plate, the output end of the servo motor is fixedly connected to one end of the rotating rod, and the guide plate has an inclined structure.

[0008] Furthermore, one side of the feed frame is connected to the opening side of the collection box via a through groove, the drop groove is connected to the collection box, the shape and size of the filter element and filter screen are adapted to the slot, and the mounting plate is fixed to the filter element and filter screen with bolts for easy and quick replacement.

[0009] This utility model has the following beneficial effects:

[0010] This invention involves feeding rice into a feeding frame, then starting a servo motor. The feeding servo motor drives a rotating rod to rotate, which in turn drives the diverter plates connected to the circumference of the rotating rod to rotate synchronously. As each diverter plate rotates, it stirs the rice in the feeding frame, making the rice in the feeding frame more loose. At the same time, multiple receiving cavities are formed between the rotating rod and two adjacent diverter plates. The rice in the feeding frame is fed into the lower cavity in sequence through the receiving cavities. Because the space of the receiving cavity is small, continuous small-volume feeding can be achieved, avoiding the problem of poor color sorting accuracy caused by feeding too much at once and causing the rice to block each other.

[0011] The rice then falls onto the deflector plates and collides. During the collision, the rice grains stuck together and the dust on the surface of the rice grains are separated from the rice grains. At the same time, the rice grains stay on the deflector plates for a longer period of time due to the deflector plates. The dust generated by the collision of the rice grains falling onto the deflector plates is cleaned up by the vacuum fan.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-4 As shown, this utility model is a rice color sorter for quantitative discharge, including a color sorter body 1. A feeding frame 2 is provided on the upper surface of the color sorter body 1. A rotating rod 210 is rotatably connected inside the feeding frame 2. Several diverting plates 211 are provided on the circumferential side of the rotating rod 210. A servo motor 21 is provided on one side of the feeding frame 2. Several guide plates 22 are provided on the two opposite surfaces of the inner wall of the feeding frame 2. A through groove 23 is opened on one side of the inner wall of the feeding frame 2. An intercepting filter screen 24 is provided in the through groove 23.

[0023] Furthermore, a collection box 3 is provided on one side of the feed frame 2, located on one side of the through groove 23. The bottom surface of the collection box 3 is symmetrically provided with sliding grooves 302. A collection box 32 is slidably connected between the two sets of sliding grooves 302. A drop groove 30 is opened on the bottom surface of the collection box 3 between the two sets of sliding grooves 302. A dust suction fan 31 is provided on one side of the collection box 3. Slots 301 are symmetrically opened on the upper surface of the collection box 3. A filter element 330 and a filter screen 331 are respectively provided in the slots 301. An installation plate 33 is provided on the upper surface of the filter element 330 and the filter screen 331.

[0024] Furthermore, the circumference diameter of the end of the diverter plate 211 is adapted to the size of the feed frame 2. The diverter plate 211 is located above the guide plate 22. The output end of the servo motor 21 is fixedly connected to one end of the rotating rod 210. The guide plate 22 has an inclined structure.

[0025] Furthermore, one side of the feed frame 2 is connected to the opening side of the collection box 3 through the through groove 23, and the drop groove 30 is connected to the collection box 32.

[0026] It should be noted that this utility model involves feeding the rice to be sorted into the feeding frame 2, then starting the servo motor 21. The feeding servo motor 21 drives the rotating rod 210 to rotate, thereby causing the diversion plates 211 connected to the circumferential side of the rotating rod 210 to rotate synchronously. When each diversion plate 211 rotates, it stirs the rice in the feeding frame 2, making the rice in the feeding frame 2 more loose. At the same time, multiple receiving cavities are formed between the rotating rod 210 and the two adjacent diversion plates 211. The rice in the feeding frame 2 is fed into the lower cavity in sequence through the receiving cavities. Since the space of the receiving cavity is small, continuous small-volume feeding can be achieved, avoiding the problem of poor color sorting accuracy caused by feeding too much at once and causing the rice to block each other.

[0027] Afterwards, the rice falls onto the deflector plate 22 and collides. During the collision, the rice grains that are stuck together and the dust on the surface of the rice grains will separate from the rice grains. At the same time, the rice grains stay on the deflector plate 22 for a longer period of time due to the presence of several deflector plates 22. The dust generated by the collision of the rice grains falling onto the deflector plate 22 is cleaned by the vacuum fan 31.
