Description

Technical Field

[0001] This utility model relates to the field of grain color sorting machine technology, and in particular to a dust removal mechanism for a grain color sorting machine. Background Technology

[0002] The grain color sorter is a new type of multi-purpose color sorter, mainly providing color sorting services for a series of grain agricultural products such as soybeans, corn, broad beans, peanuts, coffee beans, Sichuan pepper, goji berries, and chickpeas. The grain color sorter is a non-destructive sorting device used for the quality inspection and grading of bulk materials. It is a device that automatically sorts out discolored particles in granular materials based on the differences in the optical properties of the materials and using photoelectric detection technology. It has wide applications in the grain, food, pigment, and chemical industries.

[0003] In the prior art, Chinese Patent Publication No. CN201880696U discloses a dual-color grain color sorter, which consists of a vibrating feeder, a chute, a sorting chamber, a color sorting optical system, a control box, an airflow nozzle, a high-speed spray valve, and a discharge hopper. An inclined chute is set below the vibrating feeder, and the two sides of the chute are the front and rear sorting chambers, respectively. The color sorting optical system consists of a high-frequency light source, an optical lens, a background plate, a filter, and an intelligent camera. The lighting source is a white high-frequency fluorescent tube. The color sorting optical system in the front and rear sorting chambers is equipped with upper and lower sets of optical lenses, and the upper and lower sets of optical lenses are distributed at an acute angle with an acute angle of 8-15 degrees. This utility model makes the application of grain color sorters more flexible and extensive. It can be applied to the color sorting of materials with multiple defect states. The optical path system design is simple, and the installation and debugging are simple and easy. At the same time, it avoids redundant design in the structure of the color sorter.

[0004] However, in actual use, the grain color sorter is prone to dust generation at the chute and feed hopper, making dust removal difficult. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal mechanism for a grain color sorter, which can effectively remove dust over a wide range and prevent dust from being generated outside the color sorter body during operation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dust removal mechanism for a grain color sorter, comprising a color sorter body, a chute provided on the top of the color sorter body, a feed chute fixedly connected to the top of the chute, a fixing strip movably installed on one side of the color sorter body, a dust removal hood fixedly connected to one side of the fixing strip, a support rod fixedly connected to the top of the dust removal hood, a dust removal plate fixedly connected to the top of the support rod, a suction hole opened at the bottom of the dust removal plate, a suction box fixedly connected to the top of the dust removal plate, a first suction pipe and a second suction pipe respectively provided at the bottom of the suction box, a connecting pipe fixedly connected to the bottom of the first suction pipe, and a partition plate fixedly connected to the inner wall of the suction box.

The support rod supports the dust removal plate, so that the dust removal plate is installed on the top of the feed chute, which is convenient for installation. When not needed, it can be disassembled and separated from the color sorter body. The dust removal plate has a certain height and does not affect normal feeding. When the color sorter body is working, the dust raised at the chute is sucked in by the first suction pipe, and then sucked in by the connecting pipe. The connecting pipe is connected to the dust removal hood, so the dust removal hood removes dust. When dust is raised at the top of the feed chute, the second suction pipe is sucked in, and then sucked in by the suction holes. There are many suction holes, which can effectively remove dust in a wide range and avoid dust from being raised outside the color sorter body when it is working.

[0008] A further feature of this invention is that the top of the dust removal hood has a first cavity, and the top of the inner wall of the dust removal hood has a through hole.

[0009] By adopting the above technical solution, the connecting tube extends into the first cavity, thereby generating suction at the through hole.

[0010] A further feature of this invention is that the dust removal plate has a second cavity inside, and the second suction tube extends into the interior of the second cavity.

[0011] By adopting the above technical solution, the second suction tube creates negative pressure inside the second cavity, thereby enabling the suction hole to draw in air.

[0012] A further feature of this invention is that the suction box has a first negative pressure chamber and a second negative pressure chamber inside, and an air pump is fixedly connected to one side of the suction box.

[0013] By adopting the above technical solution, the first negative pressure chamber and the second negative pressure chamber are respectively equipped with air pumps, so that there is a suction negative pressure inside.

[0014] A further feature of this invention is that the output end of the air pump is fixedly connected to an air extraction pipe, and the top of the suction box is provided with a box cover.

[0015] By adopting the above technical solution, after the air pump is started, it drives the air extraction pipe to extract air.

[0017] By adopting the above technical solution, the connecting frame is rectangular in shape and has several insertion holes.

[0018] A further feature of this invention is that a plug is inserted into the inner wall of the socket, and a dust removal screen is fixedly connected to the top of the plug.

[0019] By adopting the above technical solution, the dust filter can filter dust, and the plug and socket can be connected during installation, and the dust filter can be disassembled.

[0020] A further feature of this invention is that the internal thread of the fixing strip is connected with bolts, and the number of bolts is four.

The fixing strip is installed on one side of the color sorter body, the dust hood is installed at the chute, and the support rod supports the dust removal plate, thus placing the dust removal plate on top of the feed chute for easy installation. When not needed, it can be disassembled and separated from the color sorter body. The dust removal plate has a certain height, which does not affect normal feeding. When the color sorter body is working, dust raised at the chute is sucked up by the first suction pipe, which then sucks up the dust at the connecting pipe. The connecting pipe connects to the dust hood, allowing the dust hood to remove dust. When dust rises from the top of the feed chute, the second suction pipe sucks it up, which then sucks up the dust at the suction hole. With a large number of suction holes, effective dust removal can be carried out over multiple areas, preventing dust from rising outside the color sorter body during operation.

When not needed, it can be disassembled and separated from the color sorter body 1. The dust removal plate 7 has a certain height and does not affect normal feeding. When the color sorter body 1 is working, the dust raised at the chute 2 is sucked in through the first suction pipe 10, and then through the connecting pipe 12. The connecting pipe 12 is connected to the dust hood 5, thus the dust hood 5 removes dust. When dust is raised at the top of the feed chute 3, the second suction pipe 11 sucks it in, and then through the suction holes 8. There are many suction holes 8, which can effectively remove dust over a wide range, avoiding dust from the outside of the color sorter body 1 when it is working. The top of the dust hood 5 has a first cavity 14 for dust removal. A through hole 15 is provided at the top of the inner wall of the cover 5. The connecting pipe 12 extends to the first cavity 14, thereby generating suction at the through hole 15. The dust removal plate 7 has a second cavity 16 inside. The second suction pipe 11 extends into the second cavity 16, creating a negative pressure inside the second cavity 16, thereby allowing suction holes 8 to draw in air. The suction box 9 has a first negative pressure chamber 17 and a second negative pressure chamber 18 inside. An air pump 19 is fixedly connected to one side of the suction box 9.
