Description

Technical Field

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

[0002] During rice processing, color sorting is required to remove defective rice. A search revealed a Chinese patent publication number CN222402391U that discloses a rice processing color sorter. Although this device can use a drive mechanism to move a cleaning plate back and forth on the filter screen to clean the defective rice, and a collection box can collect all the defective rice on the filter screen for unified processing, during color sorting, the dust that was not cleaned after polishing the rice will reflect light, resulting in "false color" signals, which in turn interferes with the accuracy of the color sorting sensor. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rice processing color sorter, which solves the problem mentioned in the background technology that dust not cleaned after rice polishing can easily interfere with the detection accuracy of sensors.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rice processing color sorter, comprising a support, a connecting pipe, and a baffle. A first material discharge trough is installed on the top of the support, and a feeding trough is provided above the first material discharge trough. One end of the top of the support is slidably connected to both sides of the feeding trough. The inside of the feeding trough is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the inside of a water tank. The water tank is filled with water, and three fans are installed on the top of the water tank. The bottom of the feeding trough is connected to the first material discharge trough, and a second material discharge trough is provided below the first material discharge trough. The second material discharge trough is connected to the main body of the color sorter and to the support. The main body of the color sorter is installed inside the support by bolts.

[0005] Preferably, four connecting pipes are provided, all of which are corrugated flexible hoses, with one end of each pipe extending to the bottom of the water tank. An inlet valve and a drain valve are installed on one side of the water tank. Using four corrugated flexible hoses as connecting pipes with their bottom ends extending to the bottom of the water tank allows for the formation of a multi-point uniform air intake path under the negative pressure of the fan, enhancing dust collection efficiency and system flexibility. At the same time, the inlet valve and drain valve enable rapid water replenishment and sediment discharge from the water tank, ensuring continuous and efficient operation of the water bath filtration, significantly reducing dust interference with color sorting accuracy and extending the maintenance cycle.

[0006] Preferably, a vibration motor is provided on one side of the feeding trough, and the vibration motor is connected to the feeding trough by bolts. The feeding trough has protruding structures on both sides, and a support spring is provided at the bottom of the protruding structures on both sides. One end of the support spring is connected to the bracket. The vibration motor drives the feeding trough to generate horizontal directional vibration on the support spring, which causes the dust on the surface and in the gaps of the rice to be fully lifted and efficiently captured by the negative pressure system. At the same time, the vibration can prevent material blockage, realize continuous and uniform feeding, and synergistically improve dust removal efficiency and color sorting stability.

[0007] Preferably, the feed trough has a strip-shaped groove inside, and a baffle is fixedly installed on the top of the strip-shaped groove. The bottom of the baffle is sloping, which helps to prevent the rice inside from being sucked in. The rice feeding speed is controlled so that the height of the rice material is always below the baffle.

[0008] Preferably, the color sorter has a discharge port at the bottom, and the discharge port has two channels inside, which are used by the color sorter body to distinguish different materials for discharge. The discharge port has dual channels, which can immediately separate normal rice and discolored rice grains after the color sorter body identifies them, avoid secondary mixing, improve sorting purity and yield, and simplify the downstream collection process. The electrical components mentioned in this article are all connected to an external main controller and 220V mains power. The main controller can be a conventional known device such as a computer that performs control. The color sorter body is a conventional known device that performs the color sorting function.

[0009] This utility model provides a color sorting machine for rice processing. It has the following beneficial effects:

[0010] When the rice processing color sorter is running, the raw materials are fed into the feeding trough by an external conveying device. The fan generates negative pressure at the top of the water tank, and the dust raised in the trough is sucked into the bottom of the water tank through four corrugated hoses. After the dust-laden airflow is filtered by the water bath, the dust is trapped in the water, and the clean air escapes, thereby reducing the dust content of the rice. The dust-removed rice enters the main body of the color sorter in sequence through the first and second feeding troughs, which significantly reduces the "false color difference" signal caused by residual dust from polishing and improves the sensor recognition accuracy.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] Example 1:

[0018] Please see Figure 1-4This utility model provides a technical solution: a rice processing color sorter, including a support 1, a connecting pipe 10, and a baffle 14. A first material discharge trough 2 is installed on the top of the support 1, and a feeding trough 3 is provided above the first material discharge trough 2. One end of the top of the support 1 is slidably connected to both sides of the feeding trough 3. The inside of the feeding trough 3 is connected to one end of the connecting pipe 10, and the other end of the connecting pipe 10 is connected to the inside of the water tank 9. The water tank 9 is filled with water, and three fans 11 are installed on the top of the water tank 9. The bottom of the feeding trough 3 is connected to the first material discharge trough 2. A second material discharge trough 6 is provided below the first material discharge trough 2. The second material discharge trough 6 is connected to the color sorter body 7 and the support 1. The color sorter body 7 is installed inside the support 1 by bolts. Four connecting pipes 10 are provided. The four connecting pipes 10 are corrugated hoses, and one end of the connecting pipe 10 extends to the bottom of the water tank 9. A water inlet valve 12 and a drain valve 13 are installed on one side of the water tank 9. The feed trough 3 has a slotted groove inside, and a baffle 14 is fixedly installed on the top of the slotted groove. The bottom of the baffle 14 is sloping. The bottom of the color sorter is provided with a discharge port 8, which has two channels for the color sorter body 7 to separate different materials for discharge. When the device is in use, the raw material is transported into the feed trough 3 through an external output device. Then, driven by the fan 11, the water tank 9 generates suction, which in turn generates suction in the connecting pipe 10. One end of the connecting pipe 10 can suck the dust raised inside the feed trough 3 into the water tank 9, thereby driving the dust to move into the water tank 9. Dust-laden air can float to the surface in the water inside the water tank 9. When the air carrying the dust passes through the water inside the water tank 9, the dust can be adsorbed by the water, thus filtering and collecting the dust, thereby reducing the dust in the rice raw material. Then, the rice can fall into the color sorter body 7 through the first feeding chute 2 and the second feeding chute 6 for color sorting. By collecting the dust in the raw material through the water tank 9, the interference of dust on the color sorter can be greatly reduced, which is conducive to improving the accuracy of color sorting. This solves the problem that dust that is not cleaned after rice polishing can easily interfere with the detection accuracy of the sensor.

[0019] Example 1:

[0020] Please see Figure 1-4 This utility model provides a technical solution: a rice processing color sorter, wherein a vibration motor 4 is provided on one side of the feeding trough 3, the vibration motor 4 is connected to the feeding trough 3 by bolts, the feeding trough 3 has protruding structures on both sides, and a support spring 5 is provided at the bottom of the protruding structures on both sides of the feeding trough 3, and one end of the bottom of the support spring 5 is connected to the bracket 1; when the raw material enters the feeding trough 3, the feeding trough 3 can vibrate horizontally under the drive of the vibration motor 4. While the feeding trough 3 vibrates, it can fully lift the dust in the rice, so as to facilitate the collection of the water tank 9, improve the dust removal effect of the rice, and at the same time, the vibration helps to promote the feeding of the feeding trough 3 and avoid the bottom of the feeding trough 3 from being blocked.
