The color selector can distinguish the quality of the material particles according to the colors of the material particles and reject the poor-quality particles. The color selector mainly comprises a feeding system, a sorting system, a receiving system, a gas circuit system and an electric control system. The material enters the viewpoint of the sorting system from the feeding system, whether the material is good or bad is judged through the photoelectric system of the sorting system, if the material is judged to be bad, the gas path system is driven to remove the material, and finally the material is divided into finished products and defective products through the receiving system.

Referring to fig. 1-10, a receiving system 100 according to an embodiment of the present invention is described, where the receiving system 100 can be used in a color sorter 1000 to receive materials separated by the color sorter 1000.
Specifically, the color sorter 1000 according to the embodiment of the present invention further includes a feeding system 400, a sorting system 300, an air path system, a nozzle 200, and an electric control system. When the material enters the viewpoint of the sorting system 300 from the feeding system 400, the optoelectronic system 301 of the sorting system 300 can determine whether the material is bad, and if the optoelectronic system 301 determines that the material is bad, the optoelectronic system 301 drives the gas path system to make the nozzle 200 eject the gas flow to remove the bad material, so that the bad material is separated from the good material, and the receiving system 100 can be used for receiving the material separated by the color sorter 1000. It should be noted that the structures of the feeding system 400, the sorting system 300, the air path system, the nozzle 200, the electronic control system, and the like of the color sorter 1000 and the working principle of the color sorter 1000 are well known to those skilled in the art, and will not be described in detail herein.
As shown in fig. 1, 3-4, and 7 and 9, the receiving system 100 of the color sorter 1000 according to the embodiment of the present invention may include a rebound hopper 1, a receiving hopper 2, and an auxiliary hopper 3.
Specifically, the bounce hopper 1 and the receiving hopper 2 are both located below the nozzle 200, the bounce hopper 1 is internally provided with a bounce material cavity 11, and the receiving hopper 2 is inserted into the bounce hopper 1. Alternatively, there are a plurality of receiving hoppers 2, and the plurality of receiving hoppers 2 are inserted into the rebounding hopper 1, for example, the plurality of receiving hoppers 2 are inserted into the rebounding hopper 1 side by side in the longitudinal direction of the rebounding hopper 1.
The receiving hopper 2 has a good material chamber 21 and a bad material chamber 22 therein, and the back material chamber 11, the good material chamber 21 and the bad material chamber 22 are arranged at a distance in the flowing direction of the air flow jetted from the nozzle 200. For example, as shown in fig. 1, the nozzle 200 jets the air flow from right to left, and the back material chamber 11, the good material chamber 21, and the bad material chamber 22 are arranged to be spaced apart in the direction from right to left. Therefore, when the receiving system 100 is used in the color sorter 1000 and the color sorter 1000 is in operation, when the material sent by the feeding system 400 enters the viewpoint of the sorting system 300, the photoelectric system 301 of the sorting system 300 can judge whether the material is good or bad, if the material is judged to be good, the material can be directly transferred into the good material cavity 21 under the action of gravity, and if the material is judged to be bad, the electric control system drives the gas path system to enable the nozzle 200 to eject gas flow so as to blow the bad material to the bad material cavity 22. It will be appreciated that a small amount of material is also bounced by the impact into the material bounce chamber 11 during the fall of the material. It should be noted that the above and below references to "left" and "right", "upper" and "lower" and "front" and "rear" are relative directions and are schematic illustrations according to the drawings, which should not be construed as a limitation of the present invention.
The auxiliary hopper 3 is arranged in the receiving hopper 2 and is positioned at the feeding port of the bad material cavity 22. For example, as shown in fig. 1 and 3, the auxiliary hopper 3 is disposed in the receiving hopper 2 and located on a side of the feed opening of the bad material chamber 22 adjacent to the good material chamber 21. The auxiliary hopper 3 is internally provided with an auxiliary material cavity for receiving part of the material falling to the feeding port of the bad material cavity 22, and the auxiliary material cavity is communicated with the anti-material-returning cavity 11.
Specifically, when the receiving system 100 is used in the color sorter 1000 and the color sorter 1000 is in operation, when the material sent by the feeding system 400 enters the viewpoint of the sorting system 300, the photoelectric system 301 of the sorting system 300 can determine whether the material is good or bad, if the photoelectric system 301 determines that the material is good, the material can directly fall into the good material cavity 21 under the action of gravity, and if the material is bad, the electric control system drives the gas path system to make the nozzle 200 jet the gas flow to blow the bad material to the bad material cavity 22. After the nozzle 200 ejects the gas to blow the bad materials to the bad material cavity 22, part of the tail gas in the nozzle 200 can continue to blow to the materials (which may be good materials or good materials containing bad materials) sent by the feeding system, and because the pressure of the tail gas is small, the tail gas can blow part of the materials to the material attaching cavity of the material attaching hopper 3 which is close to the nozzle 200, the materials in the material attaching cavity can directly enter the material returning cavity 11, and the part of the materials can return to the raw materials together with the materials which enter the material returning cavity 11 due to impact rebound, so that the part of the materials and the raw materials can be subjected to color sorting by the color sorter.
According to the receiving system 100 of the embodiment of the invention, when the receiving system 100 is used on the color sorter 1000 and the color sorter 1000 works, the airflow ejected by the nozzle 200 can blow the bad materials to the bad material cavity 22, the good materials fall into the good material cavity 21 through free falling, the auxiliary hopper 3 is arranged at the feed inlet of the bad material cavity 22, the auxiliary chamber of the auxiliary hopper 3 is communicated with the material returning cavity 11, after the nozzle 200 ejects gas to blow the bad materials to the bad material cavity 22, part of tail gas in the nozzle 200 can continue to blow to the materials, and because the pressure of the tail gas is small, the tail gas can blow part of the materials to the auxiliary chamber of the auxiliary hopper 3, and the materials in the auxiliary chamber can directly enter the material returning cavity 11. Therefore, after the nozzle 200 blows the bad materials, partial good materials can be prevented from being brought into the bad material cavity 22 due to the existence of tail gas of the nozzle 200, and partial bad materials can be prevented from entering the good material cavity 21 due to the fact that the adjusting plate in the material receiving hopper 2 rotates towards the bad material cavity 22 to increase the feeding hole of the good material cavity 21 in the related art, so that the color sorting taking-out ratio of the color sorter 1000 can be reduced on the basis of ensuring that the sorting rate is not reduced, and grain loss is reduced.
According to some embodiments of the present invention, as shown in fig. 3, the accessory hopper 3 includes a first regulating plate 31 and a second regulating plate 32, and the first regulating plate 31 and the second regulating plate 32 are spaced apart to define an accessory chamber. For example, as shown in fig. 3, the receiving hopper 2 includes a receiving hopper left plate 23, a receiving hopper right plate 24 and a receiving hopper partition plate 25, the second adjusting plate 32 is located at the upper end of the partition plate 25, a bad material cavity 22 is formed between the partition plate 25 and the receiving hopper left plate 23, a good material cavity 21 is formed between the partition plate 25 and the receiving hopper right plate 24, the first adjusting plate 31 is located in the bad material cavity 22, a feeding hole of the bad material cavity 22 is formed between the first adjusting plate 31 and the receiving hopper left plate 23, a feeding hole of the good material cavity 21 is formed between the second adjusting plate 32 and the receiving hopper right plate 24, and an additional material cavity is defined between the first adjusting plate 31 and the second adjusting plate 32.
At least one of the first regulating plate 31 and the second regulating plate 32 is pivotably provided on the side wall of the hopper 2. For example, the first adjusting plate 31 and the second adjusting plate 32 are pivotally connected to the side wall of the hopper 2 by a pivot shaft. When the first regulating plate 31 is pivotable, the first regulating plate 31 is rotated to regulate the sizes of the feed ports of the bad material chamber 22 and the additional material chamber; when the second regulating plate 32 is pivotable, the second regulating plate 32 is rotated to regulate the sizes of the feed ports of the good chamber 21 and the additional chamber. Therefore, the size of the feed inlet of each material cavity can be adjusted, and the material quantity entering each material cavity can be adjusted.
For example, when the receiving system 100 is used in the color sorter 1000 and the color sorter 1000 is in operation, when the material fed by the feeding system 400 enters the viewpoint of the sorting system 300, the photoelectric system 301 of the sorting system 300 can determine whether the material is good or bad, if the material is determined to be good, the material can be directly transferred into the good material cavity 21 under the action of gravity, and if the material is determined to be bad, the electric control system drives the gas path system to make the nozzle 200 eject the gas flow to blow the bad material to the bad material cavity 22. After the nozzle 200 sprays gas to blow the bad materials to the bad material cavity 22, part of tail gas in the nozzle 200 can be continuously blown to the materials sent from the feeding system 400, at the moment, the first adjusting plate 31 can be adjusted to reduce the feeding hole of the bad material cavity 22, so that the feeding hole of the auxiliary material cavity is enlarged, the materials can enter the auxiliary material cavity conveniently, under the action of the tail gas, the materials can reliably enter the auxiliary material cavity, grain loss caused by the fact that the materials enter the bad material cavity 22 is avoided, and the carrying-out ratio is reduced.
Preferably, the first adjusting plate 31 and the second adjusting plate 32 are both pivotally provided on the side wall of the receiving hopper 2. In order not to affect the rotation of the first and second adjusting plates 31 and 32, the first and second adjusting plates 31 and 32 may be provided with an escape opening to escape the structure inside the hopper 2.
Optionally, the level of the upper end of the first adjusting plate 31 is not higher than the level of the upper end of the second adjusting plate 32, which is beneficial to reducing influence on the carry-out ratio and the cleaning rate of the broken material entering the material rebounding cavity 11 due to rebounding of the first adjusting plate 31 in the falling process.

Specifically, as shown in fig. 3, the distributing hopper 4 is connected to the lower end of the attaching hopper 3, the guiding hopper 5 is connected to the right end of the distributing hopper 4, and the guiding hopper 5 is communicated with the rebounding hopper 1, so that the materials in the attaching hopper 3 sequentially pass through the distributing hopper 4 and the guiding hopper 5 and enter the rebounding hopper 1 under the action of gravity. Thereby being simple and reliable.
Optionally, as shown in fig. 2, the receiving hopper 2 and the rebounding hopper 1 are sealed by a sealing curtain 34 and a sealing curtain pressing plate 35 to prevent material leakage, thereby improving the reliability of the connection between the receiving hopper 2 and the rebounding hopper 1.

In a further embodiment of the invention, as shown in fig. 5, 8 and 10, a flow deflector 41 is provided in the partial hopper 4, the flow deflector 41 being adapted to guide the flow of material in the partial hopper 4 into the guide hopper 5. For example, a through hole is formed in a side wall or a bottom wall of the hopper 4, the through hole is connected to the material guide 5, the through hole is a feed port of the material guide 5, and the guide plate 41 can guide the material in the hopper 4 to the feed port of the material guide 5. Thereby facilitating the material to flow into the guide hopper 5 from the material distributing hopper 4. Therefore, the structure is simple and reliable. Preferably, the feeding hole of the guide hopper 5 is positioned on the right side wall of the distribution hopper 4.

For example, the upper ends of the two guide plates 41 are respectively located at the upper parts of the opposite side walls of the distribution hopper 4, the lower ends of the two guide plates 41 respectively extend to the bottom wall of the distribution hopper 4 in a direction approaching each other, and the feed inlet of the guide hopper 5 is located on the side wall of the distribution hopper 4 and is simultaneously located between the lower ends of the two guide plates 41. Therefore, when the material falls into the auxiliary hopper 3 and further enters the branch hopper 4, the material can flow along the two flow guiding plates 41 toward the middle of the bottom of the branch hopper 4 along the directions indicated by the arrows in fig. 10, and then flow toward the feeding hole of the material guiding hopper 5, so that the material can enter the material guiding hopper 5 and further enter the rebound hopper 1 through the material guiding hopper 5.
