Description

Technical Field

[0001] The utility model relates to the technical field of color sorting equipment, in particular to a rice color sorter. Background Art

[0002] A rice color sorter is a device that uses optoelectronic technology to automatically sort out different-color particles according to the optical property differences of rice.

[0003] The utility model patent with the authorized announcement number of CN207641893U discloses a rice color sorter, which includes a housing, a feed hopper, a first chute, a second chute, a color sorting box, a collection device, and a dust suction device; the first chute is located below the feed hopper; the color sorting box is arranged below the first chute; a visible light source, a background board, and a sensor are arranged in the color sorting box; the second chute is located below the color sorting box; a collection device is arranged below the second chute; dust suction devices are arranged at both ends of the housing; and a rice protection cover is arranged inside the housing for the dust suction device.

[0004] When the above patent performs color sorting on rice, impurities will cause a certain blockage to the rice, which not only increases the color sorting difficulty but also greatly reduces the color sorting accuracy of the rice. In addition, the rice also needs to be controlled separately during feeding. When there is overlap in the front and back during feeding, it will also form a blocking effect, which will lead to insufficient color sorting accuracy. To solve the above problems, we propose a rice color sorter. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and propose a rice color sorter.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0018] In the present utility model, for a rice color sorter, an impurity removal box is provided at the feeding position of the rice color sorter. An impurity removal mechanism and a feeding control mechanism are provided in the impurity removal box. In the impurity removal mechanism, air pressure is provided in the air supply cavity of the blower, so that the air cavity blows out a uniform air flow towards the inner side of the impurity removal box through the pressure equalizing air vents. When the rice falls from the impurity removal box, the impurities in the rice will be blown into the side impurity guide groove and discharged under the action of the blowing, reducing the interference of impurities on the subsequent color sorting process and improving the color sorting accuracy of the rice color sorter. In addition, in the feeding control mechanism, the gap between the two sliding plates is controlled to be 1.2 - 1.5 times the particle size of the rice, so that the rice can only pass through in a single row when it slides to the bottom of the impurity removal box, avoiding the occlusion between the rice grains during the subsequent color sorting process and further ensuring the subsequent color sorting accuracy. In addition, the gap between the two sliding plates can be adjusted by an electric telescopic rod, enabling the feeding control of rice with different particle sizes and improving the practicability.

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Referring to Figure 1-6 , please refer to Figure 1-Figure 6 , wherein, Figure 1 is a schematic three-dimensional structure diagram of a rice color sorter proposed by the present utility model Figure 1 ; Figure 2 is a schematic three-dimensional structure diagram of a rice color sorter proposed by the present utility model Figure 2 ; Figure 3 is a schematic three-dimensional structure diagram of the impurity removal box of a rice color sorter proposed by the present utility model Figure 1 ; Figure 4 is a schematic three-dimensional structure diagram of the impurity removal box of a rice color sorter proposed by the present utility model Figure 2 ; Figure 5 is a schematic three-dimensional structure diagram of the miscellaneous material guide groove; Figure 6 is a schematic three-dimensional structure diagram of the slide plate. A rice color sorter includes: a rice color sorter 1. It should be noted here that the main components inside the rice color sorter 1 include a vibrator device, a sensor and a background plate, a light source, a photoelectric detection system, an air jet valve, etc., which are conventional technical means in the prior art and will not be elaborated here. A qualified product outlet 2 and a defective product outlet 3 are provided on the rice color sorter 1. An inlet cone 6 is fixedly installed at the upper end of the rice color sorter 1. A bracket 5 is fixedly installed on the rice color sorter 1. An impurity removal box 7 is provided on the bracket 5. The bottom opening of the impurity removal box 7 is located directly above the inlet cone 6. Two side feet 8 are fixedly connected to the impurity removal box 7. The feet 8 are screwed and installed on the upper side of the bracket 5. An impurity removal mechanism and a feeding control mechanism are provided on the impurity removal box 7.

[0028] In this embodiment, the impurity removal mechanism includes an air chamber 9. The air chamber 9 is fixedly installed on the side wall of the impurity removal box 7. A plurality of air blowers 10 are installed outside the air chamber 9. An equalizing air vent 11 is opened inside the air chamber 9. A miscellaneous material guide groove 12 is provided on the opposite side of the equalizing air vent 11.

[0029] Through the above arrangement, when the equalizing air vent 11 blows air into the impurity removal box 7, the blowing direction is directly opposite to the miscellaneous material guide groove 12. Since the impurities mixed in the rice are relatively light, they are directly blown into the miscellaneous material guide groove 12 under the action of the wind force, and then discharged from the impurity removal box 7 through the miscellaneous material guide groove 12. Since the rice is relatively heavy, its falling path is slightly inclined under the action of the wind force and will not fall into the miscellaneous material guide groove 12. According to different types of rice and the impurity conditions in the rice, the output power of the air blower 10 can be controlled, and thus the air flow velocity of the equalizing air vent 11 can be controlled to achieve a better impurity removal effect.

[0030] In this method, the feeding control mechanism includes two symmetrically arranged sliding plates 14. An electric telescopic rod 17 is arranged between the sliding plate 14 and the inner wall of the impurity removal box 7. There is a gap between the two sliding plates 14, and the sliding plate 14 is in sliding contact with the inner wall of the impurity removal box 7.

[0031] Through the above settings, by starting the electric telescopic rod 17, the sliding plate 14 can be driven to slide inside the impurity removal box 7, thereby changing the gap between the two sliding plates 14 on both sides to be suitable for the feeding control of rice with different particle sizes.

[0032] In this method, a controller 4 is installed on the front side of the rice color sorter 1, and the controller 4 is electrically connected to the fan 10 and the electric telescopic rod 17 respectively.

[0033] In this method, the miscellaneous material guide groove 12 is arranged to be arc-shaped and downwardly directed. The end of the miscellaneous material guide groove 12 is fixedly connected with a mounting side plate 13, and the mounting side plate 13 is screwed to the side wall of the impurity removal box 7.

[0034] Through the above settings, the miscellaneous material guide groove 12 is screwed and installed on the side wall of the impurity removal box 7 through the mounting side plate 13, which is convenient for installation and disassembly.

[0035] In this method, the gap between the two sliding plates 14 is set to be 1.2 to 1.5 times the rice particle size.

[0036] Through the above settings, the gap between the two sliding plates 14 is set to be 1.2 to 1.5 times the rice particle size, so that the rice falling onto the sliding plate 14 can only pass through in a single row, avoiding the mutual occlusion of rice during the subsequent color sorting process and affecting the color sorting accuracy.

[0037] In this method, the sliding plate 14 is inclined, and a movable plate 20 is arranged on the upper side of the sliding plate 14. The two sides of the movable plate 20 are in sliding contact with the inner wall of the impurity removal box 7. Bottom cross plates 19 are fixedly connected to the bottom of the sliding plate 14 and the bottom of the movable plate 20 respectively. A number of groups of telescopic rods 22 are fixedly connected between the two bottom cross plates 19. A compression spring 23 is sleeved outside the telescopic rod 22. A sealing rubber plate 24 is connected between the upper side of the sliding plate 14 and the upper side of the movable plate 20. The sealing rubber plate 24 is arched, and a rubber strip 21 is installed on the upper side of the movable plate 20.

[0038] Through the above settings, the movable plate 20 is movably connected to the sliding plate 14 through the telescopic rod 22, and the movable plate 20 has a sliding degree of freedom relative to the sliding plate 14. When the movable plate 20 slides horizontally along with the sliding plate 14, at this time, under the resilience of the compression spring 23, the movable plate 20 is pushed to slide obliquely upward, so that the sealing rubber strip 21 arranged on the upper side of the movable plate 20 always remains in contact with the side wall of the impurity removal box 7, preventing rice from slipping through the gap on the side of the movable plate 20.

[0039] In this method, a first cone seat 15 and a second cone seat 16 are fixedly connected to the side of the sliding plate 14. There are two second cone seats 16, and the second cone seats 16 are symmetrically arranged along both sides of the first cone seat 15. The electric telescopic rod 17 is fixedly installed between the inner wall of the impurity removal box 7 and the first cone seat 15. Stable telescopic rods 18 are arranged on both sides of the electric telescopic rod 17, and the stable telescopic rods 18 are fixedly installed between the inner wall of the impurity removal box 7 and the second cone seat 16.

[0040] Through the above settings, the stable telescopic rods 18 are provided to make the sliding plate 14 have guiding stability when sliding under the push of the electric telescopic rod 17.

[0041] The working principle of a rice color sorter provided by the present utility model is as follows:

[0042] During use, rice is added from the upper side port of the impurity removal box 7. Under the operation of the fan 10, a certain air pressure is generated in the air cavity 9, so that a uniform air flow is blown out from the pressure equalizing air vents 11 inside the impurity removal box 7. When the rice falls inside the impurity removal box 7, it is affected by the blowing, and the lighter impurities in the rice are blown into the impurity guide groove 12 provided on the side, and are discharged from the impurity removal box 7 through the impurity guide groove 12, so as to remove impurities from the rice. When the rice falls to the bottom of the sliding plate 14 after impurity removal, since the gap between the two sliding plates 14 is set to be 1.2 - 1.5 times the rice particle size, the rice can only pass through in a single row. The rice passing through in a single row falls from the bottom of the impurity removal box 7 into the feeding cone opening 6 through the gap at the bottom of the sliding plate 14, and finally enters the rice color sorter 1 for color sorting.

[0043] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
