Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rice husk and rice separator. Background Technology

[0002] In the rice processing industry, the effective separation of rice husks and rice grains is a crucial step in ensuring rice quality and improving processing efficiency. As the core equipment in this process, the performance of the rice husk-rice separator directly impacts the operational efficiency and economic benefits of the entire rice processing production line. With the advancement of large-scale agricultural planting and the industrialization of grain processing, the market demand for automated and efficient rice processing is increasing. Traditional separation equipment can no longer fully meet the requirements of large-scale, high-quality processing. Optimization in structural design and functional implementation is necessary to address various pain points in the processing process and drive the rice processing industry towards a more efficient and stable direction.

[0003] Currently, traditional rice husk and rice separation technology mainly relies on two types of equipment: air-class separators and screening separators. Air-class separators typically consist of a fan, a bellows, a feed inlet, a rice husk outlet, and a rice outlet. The principle is that the fan continuously supplies airflow into the bellows. When the rice husk and rice mixture enters the bellows from the feed inlet, the lighter and less dense rice husks are carried by the airflow to the rice husk outlet, while the heavier and denser rice falls to the rice outlet due to gravity, thus achieving separation. Screening separators mainly consist of a frame, a drive motor, a screen, and a receiving device. The screen has a specific aperture designed according to the size difference between the rice husks and rice. The drive motor moves the screen in a reciprocating or rotating motion. When the mixture falls onto the screen, the smaller rice husks pass through the screen holes and fall into the receiving device below, while the larger rice remains on the screen and moves with the screen to the rice collection point, completing the separation operation.

[0004] Traditional air-separating and screening separators typically use simple funnel or pipe-type feeding systems, lacking precise control mechanisms for feed rate and flow rate. During continuous processing, if the feed rate is too fast, exceeding the capacity of subsequent separation components, the mixture will gradually accumulate in the feed pipe, air box inlet, or screen feed end. The accumulated mixture will not only block the conveying channel, making it difficult for materials to smoothly enter the separation stage, forcing the entire processing flow to be interrupted and reducing production efficiency, but will also cause continuous compression due to the accumulated material.

The filter screen two inside the collection box filters the material and separates the residual rice husks and dust. The filtered rice husks remain in the collection box, and the dust is discharged through pipe two, thus realizing the collection and recycling of rice husks, avoiding the waste of resources, providing high-quality raw materials for the secondary use of rice husks, reducing environmental pollution and environmental cleanup costs, and improving the recycling quality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Reference Figure 1 - Figure 7 An embodiment of this utility model is provided: a rice husk and rice separator, including a support 3, a wheel 4 arranged below the support 3, a left and right symmetrical fixing plate 2 fixedly connected to the outer wall of the support 3, an anti-accumulation component arranged on the inner wall of the fixing plate 2, a collection component arranged on the inner wall of the support 3, and a screening component arranged on the inner wall of the support 3.

[0029] The anti-accumulation component includes a material tray 16, which is positioned above two symmetrically positioned fixed plates 2. A material box 1 is fixedly connected to the inner wall of the symmetrically positioned fixed plates 2. A hopper 7 is fixedly connected to the upper surface of the material box 1. The outer wall of the material tray 16 is attached to the inner wall of the hopper 7. One end of the hopper 7 is fixedly connected to the upper surface of the material box 1. A rotating shaft 15 is connected through the inner wall of the hopper 7. One end of the rotating shaft 15 is fixedly connected to a second hopper 8, and the other end of the rotating shaft 15 is fixed to a second centrifugal block 32. The rotating shaft 15 serves as a support shaft for the rotation of the second hopper 8. When the second centrifugal block 32 drives the rotating shaft 15 to rotate, it synchronously drives the second hopper 8 to vibrate within the inner wall of the hopper 7, thus providing a vibration for the filter screen 14. The initial sieving provides the driving force. Hopper 2 8 is used to receive the rice and rice husk mixture and then perform initial sieving. A filter screen 14 is fixedly connected to the inner wall of hopper 2 8. The filter screen 14 is used for initial sieving of rice and rice husk. A limiting cylinder 19 is fixedly connected to the inner wall of hopper 2 8. A limiting cylinder 2 36 is fixedly connected through the inner wall of the material tray 16. One end of the limiting cylinder 19 is attached to the outer wall of the limiting cylinder 2 36. A reserved hole 37 is opened on the upper surface of the material box 1. The limiting cylinder 19 is used to quantitatively feed the sieved rice and rice husk mixture into the limiting cylinder 2 36. The limiting tray 16 is used to receive the rice falling from the limiting cylinder 19 of hopper 2 8, so that the quantitative feed is fed into the limiting cylinder 2 36 of the material tray 16. Then, the four limiting cylinders 2 36 on the material tray 16 rotate and interact with the material box 1. When the pre-drilled holes 37 on the upper surface are fitted, the rice husks fall into the feed box 1, thereby achieving quantitative feeding and avoiding the direct falling of rice and accumulation. A fixed box 17 is fixedly connected to the inner wall of the feed box 1, and a motor 18 is fixedly connected to the inner wall of the fixed box 17. The output end of the motor 18 is rotatably connected to the lower surface of the feed tray 16. Driven by the motor 18, the feed tray 16 can rotate at a uniform speed. The received rice is quantitatively fed into the feed box 1 through the rotational motion, effectively preventing the rice from being directly fed and accumulating. A support 6 is fixedly connected to the upper surface of the feed box 1. The feed box 1 is used to store the rice raw material to be separated. A motor 33 is fixedly connected to the upper surface of the support 6. A centrifugal block 32 is rotatably connected to the output end of the motor 33. The inner wall of the centrifugal block 32 is fixedly connected to the outer wall of the rotating shaft 15.

The rotating shaft 22 is rotatably connected to the inner wall of the fixed seats 21. The outer wall of the rotating shaft 22 is fixedly connected with a limit plate 20. The outer wall of the rotating shaft 22 is fixedly connected with a special-shaped plate 23. The special-shaped plate 23 is used to drive the limit plate 20 to rotate in the material box 1, thereby controlling the quantitative entry of rice and rice husks into the air duct 5, thereby preventing the accumulation of raw materials. The outer wall of the material box 1 is provided with a cylinder 24. The output end of the cylinder 24 is rotatably connected to one end of the special-shaped plate 23. The outer wall of the cylinder 24 is fixedly connected with a fixed plate 29. The fixed plate 29 provides support for the cylinder 24.

[0031] Specifically, motor 18 is started, driving the material tray 16 to rotate. Simultaneously, motor 33 is started, causing the centrifugal block 32 and shaft 15 to vibrate the hopper 8 against the inner wall of hopper 7. This, combined with the filter screen 14, provides initial sieving. The limiting cylinder 19 engages with the limiting cylinder 36 on the material tray 16 to achieve quantitative feeding and prevent accumulation. The rotation of the material tray 16 further rotates the limiting cylinder 36 until it aligns with the pre-drilled hole 37 in the material box 1, thus ensuring quantitative feeding and preventing accumulation. Cylinder 24 is then activated, its output end driving the... The mold plate 23 rotates around the rotating shaft 22, which drives the limiting plate 20 to adjust the amount of raw material conveyed in the material box 1, so that the raw material enters the air duct 5 in a quantitative manner. The motor 10 is started, which drives the auger rod 13 to rotate in the air duct 5, conveying the raw material to the air duct 9. At the same time, the fan 31 blows air through the air duct 9, and the air force separates part of the rice husk. The motor 34 is started, which drives the vibrating screen 11 to vibrate through the centrifugal block 30. The air duct 9 conveys the screened raw material to the vibrating screen 11, and the final separation of rice husk and rice is completed through vibration.

A vibrating screen 11 is fixedly connected to the outer wall of the collection box 26. A fan 35 is fixedly connected to the upper surface of the collection box 26. The input end of the fan 35 is fixedly connected to the inner wall of the second air duct 9, and the output end of the fan 35 is fixedly connected to the first pipe 25. The outer wall of the first pipe 25 is fixedly connected to the inner wall of the collection box 26. The first pipe 25 is used as a conveying channel for rice husks from the fan 35 to the collection box 26, so that the rice husks are transported into the collection box 26. A second filter screen 27 is fixedly connected to the inner wall of the collection box 26. The second filter screen 27 is used to perform secondary filtration on the material entering the collection box 26, so as to separate the rice husks from the dust and facilitate the subsequent recycling of the rice husks. A second pipe 28 is fixedly connected to the outer wall of the collection box 26.

[0033] Specifically, the fan 35 on the collection box 26 is started, and its output end is used to transport rice husks into the collection box 26 through pipe 25. The filter screen 27 inside the collection box 26 filters the material and separates the residual rice husks from the dust. Finally, the rice husks remain in the collection box 26, and the dust is discharged through pipe 28, thus realizing the collection and recycling of rice husks.

An auger rod 13 is fixedly connected to the output end of the motor 10. A vibrating screen 11 is fixedly connected to the lower surface of the second air duct 9. The vibrating screen 11 is mounted on the upper surface of the support 3 and completes the final screening through vibration. After secondary separation by the second air duct 9, the raw material falls into the vibrating screen 11. Under the vibration driven by the centrifugal block 30, the raw material continuously rolls and moves on the screen surface for final screening. A fixing plate 12 is fixedly connected to the outer wall of the material box 1. A fourth motor 34 is fixedly connected to the upper surface of the fixing plate 12. A centrifugal block 30 is fixedly connected to the output end of the fourth motor 34. The inner wall of the centrifugal block 30 is fixedly connected to the outer wall of the vibrating screen 11. The centrifugal block 30 is used to convert the rotational motion of the motor 34 into the vibrational motion of the vibrating screen 11, so as to perform preliminary screening of the rice and rice husk mixture in the hopper 28. The outer wall of the air duct 5 is fixedly connected to the inner wall of the material box 1. The hopper 28 is set on the inner wall of the hopper 17.

The filter screen 14 is set above the limiting cylinder 19. The cylinder 24 is set on the inner wall of the support 3. The fixing plates 29 are set on the outer wall of the air duct 5.

[0035] Working Principle: When using a rice husk and rice separator, first, the rice husk and rice mixture to be separated is placed into the feed hopper 1. Motor 2 (18) is started, its output driving the feed pan 16 to rotate. Simultaneously, motor 3 (33) drives centrifugal block 2 (32) to rotate, which in turn drives shaft 1 (15) to rotate. This causes hopper 2 (8) to vibrate against the inner wall of hopper 1 (7), coordinating with the filter screen 14 inside hopper 2 (8) for preliminary sieving. The limiting cylinder 1 (19) engages with the four limiting cylinders 2 (36) on the rotating feed pan 16, thus limiting the amount of material discharged. The rice and rice husks entering the limiting cylinders 2 (36) of the feed pan 16 are driven to rotate by the rotation of the feed pan 16, thus engaging with the pre-drilled holes 37 on the feed hopper 1 for discharge, thereby achieving limited discharge and preventing... To prevent accumulation, cylinder 24 is started, and its output end pushes the shaped plate 23 to rotate around the rotating shaft 22. The shaped plate 23 drives the limiting plate 20 to move on the inner wall of the material box 1, thereby adjusting the raw material conveying amount and ensuring that the raw material enters the air duct 5 in a quantitative manner. Then, motor 10 is started, and its output end drives the auger rod 13 to rotate in the air duct 5, thereby conveying the raw material to the air duct 9. At the same time, fan 31 blows air through the air duct 9 to perform air screening of the raw material and separate some rice husks. Then, motor 34 is started, and its output end drives the centrifugal block 30 to rotate. The centrifugal block 30 drives the vibrating screen 11 to vibrate. The air duct 9 conveys the screened raw material to the vibrating screen 11. The vibrating screen 11 further screens the raw material to achieve the final step of separating rice husks from rice.

[0036] In addition, the rice husks separated in the second duct 9 are fed by the fan 35 on the collection box 26. The fan 35 at the output end is used to transport the material to the collection box 26 through the first duct 25. The filter screen 27 in the collection box 26 filters the material and separates the residual rice husks and dust. The filtered rice husks remain in the collection box 26, while the dust is discharged through the second duct 28, thus realizing the collection and recycling of rice husks.
