Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rice storage, in particular to a rice production storage system and method. BACKGROUND

[0002] Rice is a finished product made after the processes of cleaning, hulling, milling and finished product arrangement of paddy. The rice without husk is usually stored in a storage bin before being sold in order to be processed and sold later. The rice without husk is less stable in storage than paddy because the endosperm is exposed. The rice is also affected by the external environment such as humidity and heat, and is prone to moisture absorption and deterioration. Therefore, the storage conditions of rice are harsh. In order to avoid deterioration of rice, the existing technology usually controls the storage temperature.

[0003] Although the above-mentioned method can maintain the storage temperature of rice in daily storage, the existing rice storage bin still has some deficiencies in actual use. For example, the storage bin lacks a slow cooling and dehumidifying device, so that the rice in the storage bin may be affected by temperature and humidity and cause the storage environment of the rice to heat up or return to moisture and mildew during extreme weather such as high temperature in summer or more rain in autumn. In addition, the rice after heating or moisture absorption cannot be treated by rapid cooling and dehumidification (rapid treatment may cause the rice to burst). Therefore, the temperature control or mechanical ventilation method in the existing technology cannot be used for emergency treatment of the environment. In addition, the existing storage bin also lacks subsequent filtering facilities, so that the rice in the storage bin still has the problem of containing broken rice and rice powder caused by mechanical hulling. Therefore, a rice production storage system and method are proposed to solve the existing problems. SUMMARY

[0049] This invention also discloses a storage method for a rice production storage system, specifically including the following steps:

[0050] S1. When turning the material to cool down, the operator starts the servo motor 301. After the servo motor 301 starts, the rotating shaft 302 drives the spiral blade 303 to rotate inside the conveying cylinder 304. When the spiral blade 303 rotates, it will continuously lift the rice material at the bottom of the rice storage bin 2 to the top of the conveying cylinder 304. The rice material that has been lifted to the top of the conveying cylinder 304 will slide down from the discharge hopper 305.

[0051] S2. When the rotating shaft 302 rotates, it also drives the threaded shaft 501 to rotate in conjunction. When the threaded shaft 501 rotates, the polygonal threaded bushing 502 connected to its surface threaded connection will rise due to the limiting cooperation between the first tooth pressure plate 5034 and the limiting slide frame 5033. When the polygonal threaded bushing 502 rises, it first enters the interior of its matching inner polygonal sleeve 504, then passes through the inner polygonal sleeve 504 and contacts the rotating abutment 507, and rises by pushing against the trapezoidal block 506 through the rotating abutment 507. When the trapezoidal block 506 rises, the inclined blocks 508 that are in contact with its two inclined surfaces will move in the opposite direction at the same time. When the two inclined blocks 508 move in the opposite direction, they will pull the two filter screen frames 404 to the bottom of the two hoppers 305 through the sliding plate 403 to filter the rice. Both sides of the rice storage bin 2 are provided with drive slots that slide and cooperate with the filter screen frames 404. The area of ​​the drive slots is smaller than the area of ​​the sealing plate 406. Therefore, when the filter screen frame 404 carries the sealing plate 406 to elastically reset, it can close the drive slots.

[0052] S3. During the process of the polygonal threaded bushing 502 moving in conjunction with the first toothed pressure plate 5034 to its maximum limit and the trapezoidal block 506 being pushed to its maximum limit, the first toothed pressure plate 5034 will mesh synchronously with the gear 5035 and the second toothed pressure plate 5036. When the first toothed pressure plate 5034 moves upward to mesh, the corresponding second toothed pressure plate 5036 will descend. When the second toothed pressure plate 5036 descends, it will cause the pin rod 5037 to disengage from the pin groove 5038. After the pin rod 5037 disengages from the pin groove 5038, the polygonal threaded bushing 502 will, due to the loss of its limit, abut against the bottom of the trapezoidal block 506. The threaded shaft 501 will then, through the screwing of the internal thread of the polygonal threaded bushing 502, cause the polygonal threaded bushing 502 to... As the polygonal threaded bushing 502 rotates, the inner polygonal sleeve 504 fitted outside it also rotates. The rotation of the inner polygonal sleeve 504 drives the double-sided cam 601 to rotate. After the double-sided cam 601 rotates, it will continuously press against the sliding plate 403, which has been brought closer together. When the double-sided cam 601 presses against the sliding plate 403, the sliding plate 403 will increase the movement compensation distance through the elastic sliding cooperation of the first fixed sleeve 602, the second return spring 603 and the first telescopic rod 604, thereby causing it to make a small reciprocating left and right displacement. When the sliding plate 403 moves back and forth, it will drive the filter screen frame 404 to the bottom of the hopper 305 to perform reciprocating screening without leaving the bottom receiving range of the hopper 305.

[0053] S4. During the lifting of trapezoidal block 506, the L-shaped sliding plates 5091 on the front and rear sides of trapezoidal block 506 will also be stretched upward. When the L-shaped sliding plates 5091 rise, they will pull the sealing plate 702 through the bracket and expose the ventilation opening 701. When the L-shaped sliding plates 5091 are lifted to the maximum limit with trapezoidal block 506, the L-shaped sliding plates 5091 will press the control button 704. After the control button 704 is pressed and triggered, the electric fan 703 will start automatically and form a ventilation cooperation with the two exposed ventilation openings 701.

5.

6. A storage system for rice production according to claim 5, characterized in that: Its storage method includes the following steps: S1. When turning the material to cool down, the operator starts the servo motor (301). After the servo motor (301) starts, the rotating shaft (302) drives the spiral blade (303) to rotate inside the conveying cylinder (304). When the spiral blade (303) rotates, it will continuously lift the rice material at the bottom of the rice storage bin (2) to the top of the conveying cylinder (304). The rice material that has been lifted to the top of the conveying cylinder (304) will slide down from the hopper (305). S2. When the rotating shaft (302) rotates, it will also drive the threaded shaft (501) to rotate in conjunction. When the threaded shaft (501) rotates, the polygonal threaded bushing (502) connected to its surface thread will rise due to the limiting cooperation between the first tooth pressure plate (5034) and the limiting slide frame (5033). When the polygonal threaded bushing (502) rises, it first enters the interior of its matching inner polygonal sleeve (504), then passes through the inner polygonal sleeve (504) and contacts the rotating abutment plate (507), and rises by pushing the trapezoidal block (506) through the rotating abutment plate (507). When the trapezoidal block (506) rises, the inclined blocks (508) that contact its two inclined surfaces will move in opposite directions at the same time. When the two inclined blocks (508) move in opposite directions, they will pull the two filter screen frames (404) to the bottom of the two feed hoppers (305) respectively through the sliding plate (403) to filter rice. S3. During the process of the polygonal threaded bushing (502) and the first toothed pressure plate (5034) rising to the maximum limit and the trapezoidal block (506) being pushed to the maximum limit, the first toothed pressure plate (5034) will mesh synchronously with the gear (5035) and the second toothed pressure plate (5036). When the first toothed pressure plate (5034) rises and meshes, the corresponding second toothed pressure plate (5036) will descend. When the second toothed pressure plate (5036) descends, it will drive the pin rod (5037) to disengage from the pin groove (5038). After the pin rod (5037) disengages from the pin groove (5038), the polygonal threaded bushing (502) will abut against the bottom of the trapezoidal block (506) due to the loss of its limit. The threaded shaft (501) will then rotate with the internal thread of the polygonal threaded bushing (502), thereby causing the polygonal threaded bushing (502) to move along with the first toothed pressure plate (5034). The polygonal threaded bushing (502) rotates together with the inner polygonal sleeve (504) which is sleeved on its outside. The rotation of the inner polygonal sleeve (504) drives the double-sided cam (601) to rotate. After the double-sided cam (601) rotates, it will continuously press against the sliding plate (403) which has been brought closer. When the double-sided cam (601) presses against the sliding plate (403), the sliding plate (403) will increase the movement compensation distance through the elastic sliding cooperation of the first fixed sleeve (602), the second reset spring (603) and the first telescopic rod (604), so that it can make a small reciprocating left and right displacement. When the sliding plate (403) moves back and forth, it will drive the filter screen frame (404) to the bottom of the hopper (305) and perform reciprocating screening without leaving the bottom receiving range of the hopper (305). S4. During the lifting of the trapezoidal block (506), the L-shaped sliding plates (5091) on the front and rear sides of the trapezoidal block (506) will also be stretched upward together. When the L-shaped sliding plate (5091) rises, it will pull the sealing plate (702) through the bracket and expose the ventilation opening (701). When the L-shaped sliding plate (5091) is lifted to the maximum limit with the trapezoidal block (506), the L-shaped sliding plate (5091) will press the control button (704). After the control button (704) is pressed and triggered, the electric fan (703) will start automatically and form a ventilation cooperation with the two exposed ventilation openings (701).

7. A storage system for rice production according to claim 6, characterized in that: Both sides of the rice storage bin (2) in S2 are provided with drive slots that slide and cooperate with the filter mesh frame (404). The area of ​​the drive slot is smaller than the area of ​​the sealing plate (406). Therefore, when the filter mesh frame (404) carries the sealing plate (406) to elastically reset, it can close the drive slot.
