Description

Technical Field

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

[0002] Rice is a staple food in people's lives. In order to ensure the quality of rice, it is necessary to remove rice grains of different colors, such as yellow rice, red rice, white-bellied rice, dead rice, moldy rice, and black diseased rice.

[0003] For example, the authorization announcement number "CN211937972U" describes a rice color sorter equipped with an air extraction pipe. This pipe creates negative pressure, facilitating the adsorption of rice grains and allowing each grain to pass through the color sorting device at a uniform speed. However, existing rice color sorters, due to the extremely small and fragile nature of rice grains, can only sort one grain at a time with the rotating air extraction pipe. Furthermore, to ensure accuracy, the rotation speed of the separating disc driving the rice is limited. Consequently, for a large quantity of rice, only a small amount can be sorted within a short period, resulting in excessively slow speed and long sorting time, thus affecting the overall efficiency of the rice color sorter. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of low color sorting efficiency of existing rice color sorters, and to propose a rice color sorter.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a rice color sorter, including a base, side plates, and a rice storage bin. The two side plates are fixedly installed on the top two sides of the base, and the rice storage bin is fixedly installed inside the top of the side plates. A rice discharge structure is provided below the rice storage bin, and a dual-stage high-efficiency rice color sorting structure is provided inside the side plates. A rice color sorting device is provided above the base.

[0007] Preferably, the rice dual-stage high-efficiency color sorting structure includes connecting blocks and positioning frames. Two connecting blocks are fixedly connected to the inner wall of the side plate, and the other end of the two connecting blocks is fixedly installed with a positioning frame. Multiple primary screening tubes are fixedly connected to the inner side of the positioning frame. Funnels are fixedly connected to the top of the multiple primary screening tubes. Secondary screening tubes are fixedly connected to the bottom of the multiple primary screening tubes. Discharge solenoid valves are fixedly installed at the lower ends of the multiple secondary screening tubes.

[0008] Preferably, the rice color sorting device includes a first support plate and a second support plate. The first support plate is fixedly installed on the rear side of the top of the base, and the second support plate is fixedly connected to the top of the first support plate. Multiple CCD sensors are fixedly connected to the front ends of both the first and second support plates, and lighting tubes are fixedly installed on the outer walls of the first and second support plates.

[0009] Preferably, the front ends of the plurality of CCD sensors are arranged opposite to the rear side of the primary screening tube, and the front ends of the plurality of CCD sensors are also arranged opposite to the rear side of the outer wall of the secondary screening tube.

[0010] Preferably, the rice discharge structure includes a feeding port and discharge pipes, with multiple discharge pipes fixedly installed at the bottom of the rice storage box, and feeding solenoid valves fixedly installed on the outside of the multiple discharge pipes. The feeding port is fixedly located at the top of the rice storage box.

[0011] Preferably, a positioning platform is fixedly installed at the top of the base, and a material picking groove is fixedly opened at the top of the positioning platform. The top of the material picking groove is arranged opposite to the bottom of the multiple secondary screening tubes.

[0012] The rice color sorter proposed in this utility model has the following advantages: the primary screening tube is made of multiple vertical transparent glass tubes, which can store a large number of rice grains. Then, the diameter of the primary screening tube suddenly decreases from the bottom to the secondary screening tube, allowing only a small number of rice grains to enter the secondary screening tube. As the discharge solenoid valve at the bottom opens, the rice grains inside the secondary screening tube are discharged little by little. In this way, a large batch of rice can be sorted at the same time each time, without waiting for the separation disc to slowly rotate, thus improving the sorting efficiency of the rice color sorter.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a rice color sorter includes a base 1, side plates 2, and a rice storage bin 3. The two side plates 2 are fixedly installed on the top two sides of the base 1, and the rice storage bin 3 is fixedly installed inside the top of the side plates 2. The rice storage bin 3 is fixed to the top of the side plates 2. The operator can pour the rice that needs to be color sorted into the rice storage bin 3 for storage. The rice storage bin 3 is provided with a rice discharge structure 4 below it. The side plates 2 are provided with a dual-stage high-efficiency rice color sorting structure 5 inside them. The base 1 is provided with a rice color sorting device 6 above it.

[0023] The rice dual-stage high-efficiency color sorting structure 5 includes connecting blocks 51 and positioning frames 52. Two connecting blocks 51 are fixedly connected to the inner wall of the side plate 2. The connecting blocks 51 are welded to the middle positioning frame 52, which is then fixed inside the side plate 2. The top of the primary screening tube 54 inside the positioning frame 52 is aligned with the bottom of the rice storage bin 3. The other end of the two connecting blocks 51 is fixedly installed with the positioning frame 52. Multiple primary screening tubes 54 are fixedly connected to the inner side of the positioning frame 52. The primary screening tubes 54 are made of multiple vertical transparent glass tubes. The diameter of the primary screening tube 54 is slightly larger than that of the lower secondary screening tube 55, allowing it to store a larger amount of rice grains. Then, the diameter suddenly decreases between the bottom of the primary screening tube 54 and the secondary screening tube 55, allowing only a small amount of rice grains to enter the lower secondary screening tube 55. As the bottom discharge solenoid valve 56 opens, the rice grains inside the secondary screening tube 55 are gradually discharged downwards. This ensures that each rice color sorting operation can simultaneously complete the sorting of large and small rice grains.

[0024] In batch rice color sorting operations, there is no need to wait for the separation disc to slowly rotate. The top of multiple primary screening tubes 54 is fixedly connected to a funnel 53, which can guide the falling rice into the inside of the primary screening tubes 54. The bottom of multiple primary screening tubes 54 is fixedly connected to a secondary screening tube 55, and the lower end of multiple secondary screening tubes 55 is fixedly installed with a discharge solenoid valve 56.

[0025] The rice color sorting device 6 includes a first support plate 61 and a second support plate 62. The first support plate 61 is fixedly installed on the rear top of the base 1. The second support plate 62 is vertically welded to the top of the first support plate 61 and is fixedly connected to the top of the first support plate 61. The first support plate 62 aligns a row of CCD sensors 63 with the secondary screening tube 55. This, combined with the illumination from the rear lighting tube 64, allows for sequential color sorting of the rice passing through the finer secondary screening tube 55. Simultaneously, the upper second support plate 62 aligns another row of CCD sensors 63 with the primary screening tube 54, using the same... The principle is to perform a pre-selection of the larger quantity of rice inside the primary screening tube 54, improving the accuracy of color sorting. Multiple CCD sensors 63 are fixedly connected to the front ends of both the first support plate 61 and the second support plate 62. The CCD sensors 63 are mature existing technology. The CCD sensors 63 identify and detect the color of the rice grains and transmit the detected data to the controller. The controller analyzes the detection signals to determine the quality of the rice grains. Illumination tubes 64, made of LEDs, are fixedly installed on the outer walls of the first support plate 61 and the second support plate 62, producing bright white light when powered. The front ends of the multiple CCD sensors 63 are positioned opposite the rear side of the primary screening tube 54, and also opposite the rear side of the outer wall of the secondary screening tube 55.

[0026] The rice discharge structure 4 includes a feeding port 41 and a discharge pipe 43. The discharge pipes 43 are arranged side by side, and the lower end of the discharge pipes 43 faces a row of funnels 53. Multiple discharge pipes 43 are fixedly installed at the bottom of the rice storage box 3. Feeding solenoid valves 42 are fixedly installed on the outside of the multiple discharge pipes 43. The feeding solenoid valves 42 can be remotely operated by a PLC controller or manually activated by a button. The feeding port 41 is fixedly opened at the top of the rice storage box 3. The feeding port 41 is cut at the top to facilitate the pouring of rice into the inside of the rice storage box 3.

[0027] A positioning platform 71 is fixedly installed on the top of the base 1. The positioning platform 71 supports the feeding trough 72 on the lower end of multiple secondary screening tubes 55. In this way, the rice that has been color sorted can fall onto the feeding trough 72, and then the staff can spread the rice out to make it easier to pick out the rice with different colors. The top of the positioning platform 71 is fixedly provided with the feeding trough 72, and the top of the feeding trough 72 is set opposite to the bottom of the multiple secondary screening tubes 55.

[0028] Working principle:

[0029] Rice color sorters use color screening to pick out rice grains that do not match the milky white color. They can select and remove rice grains of different colors such as yellow rice, red rice, white-bellied rice, dead rice, moldy rice, and black diseased rice.

[0030] The discharge pipes 43 are arranged side by side, and the lower end of the discharge pipes 43 is directly opposite a row of funnels 53. The feed solenoid valves 42 can be remotely operated by the PLC controller or manually controlled by a button to open the corresponding feed solenoid valves 42. The discharge pipes 43 can pour rice into the lower vertical primary screening pipe 54. The feeding port 41 is cut at the top to facilitate the pouring of rice into the rice storage box 3.

[0031] The connecting block 51 is welded to fix the middle positioning frame 52 inside the side plate 2. The top of the primary screening tube 54 inside the positioning frame 52 is aligned with the bottom of the rice storage box 3. The primary screening tube 54 is made of multiple vertical transparent glass tubes. The diameter of the primary screening tube 54 is slightly larger than that of the lower secondary screening tube 55. Therefore, the primary screening tube 54 can store more rice grains. Then, the diameter between the bottom of the primary screening tube 54 and the secondary screening tube 55 will suddenly decrease, so that only a small amount of rice grains can enter the lower secondary screening tube 55. As the discharge solenoid valve 56 at the bottom opens, the rice grains inside the secondary screening tube 55 will be discharged little by little. In this way, a large batch of rice color sorting operations can be completed at the same time each time rice color sorting is performed, without waiting for the separation disc to slowly rotate.

[0032] The second support plate 62 is vertically welded to the top of the first support plate 61. The first support plate 62 has a row of CCD sensors 63 aligned with the secondary screening tube 55. This, together with the illumination from the rear lighting tube 64, can sequentially detect and color-sort the rice passing through the finer secondary screening tube 55. At the same time, the upper second support plate 62 will align another row of CCD sensors 63 with the primary screening tube 54. Using the same principle, it will perform a pre-selection of the larger amount of rice in the primary screening tube 54, improving the color sorting accuracy. The CCD sensor 63 is a mature existing technology. The CCD sensor 63 identifies and detects the color of the rice grains and transmits the detected data to the controller. The controller analyzes the detection signal and then judges the quality of the rice grains. The lighting tube 64 is made of LED light and can produce relatively bright white light when powered on.

[0033] The positioning platform 71 supports the feeding trough 72 at the lower end of multiple secondary screening tubes 55, so that the color-sorted rice can fall onto the feeding trough 72, and then the staff can spread the rice out to make it easier to pick out the rice with different colors.
