Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice husk recycling technology, and in particular to a rice husk recycling device. Background Technology
[0002] Rice husks are a byproduct of rice processing, forming a hard protective layer on the outer surface of rice grains composed of cellulose, lignin, and silica. Inside the rice mill, rice grains pass through the gap between the threshing drum and the concave plate. Under the impact and friction forces generated by the high-speed rotation, the grains are separated from the rice. The husks then enter the cleaning system through a grid-like concave plate, where airflow separation technology is used. A fan generates airflow that blows the lighter husks into a dedicated collection channel, while the denser grains settle to a vibrating screen. Finally, they undergo secondary separation in a gravity settling chamber.
[0003] Existing rice husk recycling devices have the following problems: When the blower generates airflow to blow the lightweight rice husks into the dedicated collection channel, due to the long collection channel, some rice husks will accumulate at the bottom of the collection channel, thereby reducing the space of the collection channel and requiring regular cleaning, which affects the rice husk recycling efficiency. Utility Model Content
[0004] In view of this, the present invention proposes a rice husk recycling device to solve the problems mentioned above.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A rice husk recycling device includes a support plate, a rice milling machine, a shell, and a wall. The support plate and the rice milling machine are sequentially arranged on the ground. The shell is fixedly mounted on the top of the support plate. The shell has a cavity that communicates with the rice husk discharge channel of the rice milling machine. A discharge channel is provided on the side of the shell and communicates with the cavity. A fan is provided inside the cavity and is located at the entrance of the discharge channel. The fan is driven by a drive mechanism via a rotating shaft. The drive mechanism is located on the side of the shell. A cylindrical cloth bag is connected to the discharge channel. The cylindrical cloth bag passes through the wall and is connected to a vertical pipe. The vertical pipe is located on the side of the wall and has a discharge pipe at its bottom. A discharge valve is provided on the discharge pipe. A moving mechanism is provided on the ground below the cylindrical cloth bag. A peristaltic mechanism is provided at the top of the moving mechanism. The peristaltic mechanism includes a first electric push rod, a U-shaped frame, and a roller mechanism. The first electric push rod is located at the top of the moving mechanism and its telescopic end is connected to the U-shaped frame. The roller mechanism is rotatably located in the middle of the U-shaped frame.
[0007] Preferably, the drive mechanism includes a first motor, a driving pulley, a driven pulley, and a belt.

[0008] Preferably, the moving mechanism includes a support plate, a slide rail, a lead screw, a second motor, and a moving block. The support plate is located on the ground. The lead screw is rotatably located between the support plate and the support plate, with one end rotatably connected to the support plate and the other end passing through the support plate and driving the second motor. The second motor is located on the side of the support plate. The moving block is located on the lead screw and its bottom is slidably connected to the slide rail, which is located on the ground.
[0009] Preferably, the roller mechanism includes a connecting plate, a second rotating shaft, a roller, a third rotating shaft, and a third motor.

[0021] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.
[0022] See Figures 1 to 4This utility model provides a rice husk recycling device, including a support plate 15, a rice milling machine 36, a shell 1, and a wall 28. The support plate 15 and the rice milling machine 36 are sequentially arranged on the ground. The shell 1 is fixedly installed on the top of the support plate 15. The shell 1 has a cavity 2 inside, which is connected to the rice husk discharge channel of the rice milling machine 36. The side of the shell 1 has a discharge channel 4, which is connected to the cavity 2. A fan 6 is installed inside the cavity 2. The fan 6 is located at the inlet of the discharge channel 4. The fan 6 is driven by a drive mechanism via a rotating shaft 5. The drive mechanism is located on the shell. On the side of body 1, the discharge channel 4 is connected to a cylindrical cloth bag 11. The cylindrical cloth bag 11 passes through the wall 28 and is connected to the vertical pipe 12. The vertical pipe 12 is located on the side of the wall 28, and a discharge pipe 13 is provided at its bottom. A discharge valve 14 is provided on the discharge pipe 13. A moving mechanism is provided on the ground below the cylindrical cloth bag 11. A peristaltic mechanism is provided at the top of the moving mechanism. The peristaltic mechanism includes a first electric push rod 21, a U-shaped frame 23 and a roller mechanism. The first electric push rod 21 is located at the top of the moving mechanism, and its telescopic end is connected to the U-shaped frame 23. The roller mechanism is rotatably located in the middle of the U-shaped frame 23.
[0023] When the rice milling machine 36 starts, the rice grains are threshed and separated, and the resulting husks enter the cavity 2 through the discharge channel. The drive mechanism is activated, driving the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the fan 6 to rotate, generating airflow. The airflow enters from the inlet of the discharge channel 4 and exits from the outlet, creating a negative pressure zone in the cavity 2. This rapidly draws the husks from the discharge channel of the rice milling machine 36 into the discharge channel 4. The airflow then carries the husks out of the discharge channel 4 and moves them inside the cylindrical bag 11. Simultaneously, the peristaltic mechanism is activated. First, the first electric push rod 21 is activated, and the extension end of the first electric push rod 21 extends, causing the U-shaped frame 23 to rise. The roller mechanism abuts against the cylindrical bag 11 and continues to rise, causing the cylindrical bag 11 to deform into waves. Then, the moving mechanism is activated, driving the roller mechanism to move laterally towards the vertical tube 12, thereby... The wavy deformation of the cylindrical bag 11 causes it to move laterally from the discharge port to one side of the vertical pipe 12. When the roller mechanism reaches the side of the vertical pipe 12, the first electric push rod 21 is activated. The telescopic end of the first electric push rod 21 shortens, causing the U-shaped frame 23 to descend. The roller mechanism descends and disengages from the bottom of the cylindrical bag 11. Driven by the moving mechanism, it moves laterally back to the initial position of the discharge channel 4. Then, the above actions are repeated. Under the continuous push of the roller mechanism, the rice husks in the cylindrical bag 11 finally enter the vertical pipe 12, improving their fluidity and avoiding local accumulation. After entering the vertical pipe 12, the rice husks fall into the discharge pipe at the bottom under the action of gravity. The airflow is discharged through the top opening of the vertical pipe 12. The operator opens the discharge valve 14 at the bottom of the vertical pipe 12, and the rice husks are discharged from the discharge pipe 13, thereby realizing the recycling of rice husks.
[0024] Preferably, the drive mechanism includes a first motor 10, a driving pulley 8, a driven pulley 7, and a belt 9. The first motor 10 is located on the top surface of the housing 1, and its output shaft is driven by the driving pulley 8. The driven pulley 7 is sleeved on the rotating shaft 5, and the driving pulley 8 is driven by the driven pulley 7 through the belt 9.
[0025] The drive mechanism is used to drive the fan 6 to rotate. First, the first motor 10 is started. The rotation of the first motor 10 drives the active pulley 8 to rotate. The active pulley 8 is connected to the driven pulley 7 through the belt 9. The rotation of the driven pulley 7 drives the rotating shaft 5 to rotate, thereby driving the fan 6 to rotate and generating directional airflow. The airflow flows out from the discharge channel 4 and blows the rice husks out of the cavity 2 at the same time.
[0026] Preferably, the moving mechanism includes a support plate 17, a slide rail 18, a lead screw 16, a second motor 19, and a moving block 20. The support plate 17 is located on the ground. The lead screw 16 is rotatably located between the support plate 15 and the support plate 17, with one end rotatably connected to the support plate 17 and the other end passing through the support plate 15 and driving the second motor 19. The second motor 19 is located on the side of the support plate 15. The moving block 20 is located on the lead screw 16 and its bottom is slidably connected to the slide rail 18, which is located on the ground.
[0027] The moving mechanism drives the peristaltic mechanism to reciprocate, causing the cylindrical bag 11 to peristalse and continuously push the rice husks towards the vertical tube 12, preventing the rice husks from accumulating at the bottom of the cylindrical bag 11. When the moving mechanism is working, the second motor 19 is first started. The rotation of the second motor 19 drives the lead screw 16 to rotate. The rotation of the lead screw 16 drives the moving block 20 to move along the axis of the lead screw 16. At the same time, the moving block 20 slides along the slide rail 18, which can maintain smooth movement. By changing the rotation direction of the second motor 19, the peristaltic mechanism can be driven to reciprocate.
[0028] Preferably, the roller mechanism includes a connecting plate 25, a second rotating shaft 24, a roller 27, a third rotating shaft 26, and a third motor 22. Multiple second rotating shafts 24 are disposed between two connecting plates 25. The roller 27 is sleeved on the second rotating shaft 24. The two sides of the connecting plate 25 are rotatably disposed in the middle of the U-shaped frame 23 via the third rotating shaft 26. One of the third rotating shafts 26 passes through the U-shaped frame 23 and is driven by the third motor 22. The third motor 22 is disposed on the side of the U-shaped frame 23.
[0029] When the peristaltic mechanism is working, the telescopic end of the first electric push rod 21 extends, causing the roller mechanism to abut against the bottom of the cylindrical bag 11. Then, the third motor 22 is started. The rotation of the third motor 22 drives the rotating shaft 26 to rotate, driving the connecting plate 25 to rotate around the rotating shaft 26. This causes multiple rollers 27 to rotate around the rotating shaft 26. The rollers 27 continuously push the cylindrical bag 11, causing it to deform in waves. The rice husks inside the cylindrical bag 11 are turned over by the continuous push of the roller mechanism. Under the action of the airflow generated by the fan 6, the fluidity is improved. Then, the peristaltic mechanism moves laterally towards the vertical pipe 12 under the drive of the moving mechanism, causing the cylindrical bag 11 to deform in waves and move continuously towards the vertical pipe 12. The rice husks are continuously moved by the continuous push of the rollers 27, improving their fluidity and preventing local accumulation.
[0030] Preferably, the bottom of the cavity 2 is provided with an inclined part 3, and the lower part of the inclined part 3 is connected to the discharge channel 4.
[0031] The bottom of the cavity 2 is provided with an inclined part 3. Under the action of gravity, the rice husks slide down the inclined part 3 to a lower position, which is conducive to the rice husks being discharged from the cavity 2 through the discharge channel 4 and reducing residue.
[0032] Preferably, a suspension mechanism is also included, which includes a second electric actuator 29, a crossbeam 30, suspension ropes 31, hooks 32, shackles, and straps 34. The second electric actuator 29 is located at the top of the wall 28, and its telescopic end is connected to the crossbeam 30. A plurality of suspension ropes 31 are spaced apart at the bottom of the crossbeam 30, and the bottom end of each suspension rope 31 is connected to a hook 32. One end of each of the straps 34 is fixedly connected to both sides of the cylindrical cloth bag 11 at intervals, and the other end is connected to a shackle, which is suspended from the hook 32.
[0033] The suspension mechanism is used to support the cylindrical cloth bag 11 and keep it in a horizontal position. First, the cylindrical cloth bag 11 is connected to the discharge channel 4. Then, the second electric actuator 29 is activated. The extension end of the second electric actuator 29 extends, causing the crossbeam 30 to descend. The hook 32 descends together with the lifting rope 31. The operator puts the lifting rings connected to both sides of the cylindrical cloth bag 11 onto the hook 32. Then, the second electric actuator 29 is activated again. The extension end of the second electric actuator 29 shortens, causing the crossbeam 30 to rise. The cylindrical cloth bag 11 is at a certain height and remains horizontal, which is conducive to the rice husks moving to the vertical pipe 12 outside the wall 28 under the action of airflow.
[0034] Preferably, a rain cap is also included, which is located at the top opening of the vertical tube 12.
[0035] The rain cap is located at the top opening of the vertical pipe 12 to prevent rainwater and other debris from entering the vertical pipe 12 and contaminating the rice husks.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
