Description

Technical Field

[0001] This utility model belongs to the technical field of grain processing equipment, specifically a material guiding structure for a rice color sorter. Background Technology

[0002] Rice color sorters are an important component of modern grain processing equipment. Their core function is to accurately screen out discolored and irregularly shaped impurities from granular materials based on differences in color or shape, using photoelectric technology. In this process, the material guide structure, as a crucial component connecting the feeding area and the color sorting area, directly impacts the material flow, sorting effect, and overall performance of the color sorter. With its precise design and suitable installation angle, the material guide structure leads the material smoothly down a predetermined path, ensuring that it enters the color sorting area evenly and orderly. This significant feature helps reduce blockages and accumulation of material during the flow process, thereby greatly improving color sorting efficiency.

[0003] The existing technology still has the following shortcomings:

[0004] 1. The existing rice color sorter's feeding structure lacks a pre-treatment function for rice during use. The rice is mixed with a large number of impurities before entering the color sorter, which greatly reduces the efficiency of the color sorter and cannot guarantee the purity of the rice after color sorting.

[0005] 2. The existing rice color sorter's feeding structure lacks the function of evenly spreading the rice during use. The rice piled up will also reduce the color sorting efficiency of the color sorter and make it impossible to completely remove impurities. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a material guiding structure for a rice color sorter, which solves the problems of lack of pretreatment and uniform spreading of rice.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a material guiding structure for a rice color sorter, including a hoist housing, a conveying mechanism being provided inside the hoist housing, and a filtering mechanism and a spreading mechanism being provided on one side of the hoist housing.

[0008] As a further embodiment of this utility model: two rollers are rotatably connected inside the housing of the elevator, a conveyor belt is sleeved between the two rollers, a partition is fixedly connected to the outside of the conveyor belt, a motor is fixedly connected to one side of the housing of the elevator, and the output end of the motor is coaxially fixedly connected to one of the rollers.

[0009] As a further embodiment of this utility model: two pulleys are rotatably connected to both sides of the elevator housing, and the two pulleys are coaxially and fixedly connected to another roller.

[0010] As a further embodiment of this utility model: a body is fixedly connected to one side of the hoist housing, and two pulleys are rotatably connected to both sides of the body, with a belt sleeved between the pulleys on the same side and the pulleys on the same side.

[0011] As a further embodiment of this utility model: the machine body is provided with a plurality of spring telescopic rods inside, the bottom of the spring telescopic rods being fixedly connected to the inner wall of the machine body, and the machine body is provided with a sieve plate inside, the sieve plate being fixedly connected to the top of the spring telescopic rods.

[0012] As a further embodiment of this utility model: eccentric wheels are rotatably connected to both sides of the inner wall of the machine body, and the two eccentric wheels are fixedly connected to two pulleys respectively. A connecting rod is rotatably connected to one side of the two eccentric wheels. A spreading plate is rotatably connected inside the machine body, and two fixing blocks are fixedly connected to the spreading plate. The two fixing blocks are rotatably connected to the other end of the two connecting rods respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up a vibration screening mechanism, rice can be pre-treated before entering the color sorter, separating out larger impurities in the rice, reducing the load on the color sorter, improving color sorting efficiency, and ensuring the purity of the rice after color sorting.

[0015] 2. By setting up a spreading mechanism, the action of manually using a winnowing basket to remove impurities is simulated, which can remove relatively small and light impurities from rice. At the same time, the screened rice is spread out evenly, further improving the color sorting efficiency. This utility model also has the characteristics of simple operation, reliable structure and low equipment cost. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution:

[0022] A material guiding structure for a rice color sorter includes a hoist housing 1, a conveying mechanism is provided inside the hoist housing 1, and a filtering mechanism and a spreading mechanism are provided on one side of the hoist housing 1.

[0023] Inside the elevator housing 1, two rollers 2 are rotatably connected, and a conveyor belt 3 is fitted between the two rollers 2. A partition 4 is fixedly connected to the outside of the conveyor belt 3. A motor 5 is fixedly connected to one side of the elevator housing 1, and the output end of the motor 5 is coaxially fixedly connected to one of the rollers 2. When the motor 5 is started, it drives the roller 2 to rotate, and the roller 2 drives the conveyor belt 3, so that the partition 4 transports the rice to the top of the machine body 7. Pulleys 6 are rotatably connected to both sides of the elevator housing 1, and each of the two pulleys 6 is coaxially fixedly connected to another roller 2. When the driven roller 2 rotates, it drives the pulley 6 to rotate. A body 7 is fixedly connected to one side of the elevator casing 1. Two pulleys 8 are rotatably connected to both sides of the body 7. A belt is fitted between pulley 6 and pulley 8 on the same side. Pulley 6 drives pulley 8, which is connected to it by the belt, to rotate. Several spring-loaded telescopic rods 10 are installed inside the body 7. The bottom of each spring-loaded telescopic rod 10 is fixedly connected to the inner wall of the body 7. A screen plate 9 is installed inside the body 7. The screen plate 9 is fixedly connected to the top of each spring-loaded telescopic rod 10. Eccentric wheels 11 are rotatably connected to both sides of the inner wall of the body 7. Two eccentric wheels 11 are fixedly connected to two pulleys 8 respectively. A connecting rod 12 is rotatably connected to one side of each eccentric wheel 11. The internal rotating connection includes a spreading plate 14, on which two fixed blocks 13 are fixedly connected. The two fixed blocks 13 are rotatably connected to the other ends of two connecting rods 12 respectively. The pulley 8 drives the eccentric wheel 11 to rotate, causing the sieve plate 9, which is connected to the machine body 7 through the spring telescopic rod 10, to screen the rice. The screened rice falls onto the spreading plate 14. The eccentric wheel 11 is connected to one side of the spreading plate 14 through the connecting rod 12 and the fixed blocks 13. The other side of the spreading plate 14 is rotatably connected to the machine body 7 through the rotating shaft. When the eccentric wheel 11 rotates, the spreading plate 14 simulates the action of manually using a winnowing basket to remove impurities, removing the smaller and lighter impurities in the rice and spreading them evenly, and finally entering the color sorter.

[0024] The working principle of this utility model is as follows:

[0025] First, the motor 5 is started, driving the roller 2 to rotate. The roller 2 drives the conveyor belt 3, which causes the partition 4 to transport the rice to the top of the machine body 7. The driven roller 2 rotates, driving the pulley 6 to rotate. The pulley 6 drives the pulley 8 connected to it by the belt to rotate. The pulley 8 drives the eccentric wheel 11 to rotate, causing the sieve plate 9, which is connected to the machine body 7 by the spring telescopic rod 10, to screen the rice. The screened rice falls onto the spreading plate 14. The eccentric wheel 11 is connected to one side of the spreading plate 14 through the connecting rod 12 and the fixing block 13. The other side of the spreading plate 14 is rotatably connected to the machine body 7 through the rotating shaft. When the eccentric wheel 11 rotates, the spreading plate 14 simulates the action of manually using a winnowing basket to remove impurities, removing the smaller and lighter impurities in the rice and spreading it evenly. Finally, the rice enters the color sorter.
