Description

Technical Field

[0001] This utility model relates to the field of rice preservation technology, and in particular to rice fumigation and preservation equipment. Background Technology

[0002] Rice fumigation is a process that uses hot steam to treat rice, extending its shelf life, maintaining its freshness, improving its quality, reducing losses, and ensuring it meets food safety standards. This process enhances the overall quality and market competitiveness of rice by killing microorganisms, removing odors, and improving taste.

[0003] For example, a Chinese patent discloses a sprout-suppressing fumigation device (patent number: CN218008007U). A heating device accelerates the evaporation and diffusion of the solution in the storage tank; a blowing device guides the volatile gaseous chloroaniline to the outlet duct. Chloroaniline has a significant sprout-suppressing ability, thus ensuring efficient sprout suppression of potatoes in the storage facility. The heating device, blowing device, and outlet duct work together to ensure sufficient and uniform chloroaniline gas in the storage facility, thereby guaranteeing timely and efficient sprout suppression of potatoes. This sprout-suppressing fumigation device features a simple structure, high sprout suppression efficiency, and stable and reliable sprout suppression performance, thus offering significant economic benefits.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, the device can only perform fumigation treatment on exposed materials. When materials are piled up, the materials piled up inside may not be fumigated, which may result in the situation where the external fumigation is completed but the internal fumigation has not been carried out, affecting the quality of material fumigation.

[0017] (III) Beneficial Effects

[0018] 1. By starting the motor, the motor drives the rotating rod to rotate counterclockwise. The rotating rod drives the transmission assembly to rotate counterclockwise, which in turn drives the rotating shaft to rotate counterclockwise. The rotating shaft drives the rotating ring to rotate counterclockwise, which in turn drives the stirring blade to rotate counterclockwise. Simultaneously, the rotating rod drives the first bevel gear to rotate counterclockwise, which in turn drives the second bevel gear to rotate clockwise. The second bevel gear drives the connecting rod to rotate clockwise, which in turn drives the missing gear to rotate clockwise. The missing gear drives the rack frame to reciprocate up and down, which in turn drives the rotating shaft to reciprocate up and down. This causes the stirring blade to rotate while reciprocating up and down inside the fumigation chamber, ensuring that the rice inside the fumigation chamber is heated more evenly during the fumigation process. This helps to avoid hot or cold spots in the rice during fumigation, improving the quality of rice fumigation and thus achieving the function of improving the quality of rice fumigation.

Detailed Implementation

[0026] This application provides a rice fumigation and preservation device, effectively solving the problem mentioned above that the device can only fumigate exposed materials. When materials are piled up, the material piled inside may not be fumigated, resulting in a situation where external fumigation is completed but internal fumigation is not, affecting the quality of material fumigation. By starting the motor, the motor drives the rotating rod to rotate counterclockwise, the rotating rod drives the transmission component to rotate counterclockwise, the transmission component drives the rotating shaft to rotate counterclockwise, the rotating shaft drives the rotating ring to rotate counterclockwise, the rotating shaft drives the stirring blade to rotate counterclockwise, the rotating rod simultaneously drives the first bevel gear to rotate counterclockwise, the first bevel gear drives the second bevel gear to rotate clockwise, the second bevel gear drives the connecting rod to rotate clockwise, the connecting rod drives the missing gear to rotate clockwise, and the missing gear drives the rack. The frame moves up and down reciprocally, and the rack and pinion frame drives the rotating shaft to move up and down reciprocally, causing the stirring blades to rotate while moving up and down inside the fumigation chamber. This ensures that the rice inside the fumigation chamber is heated more evenly during the fumigation process, helping to avoid hot or cold spots and improving the quality of rice fumigation. By activating the cylinder, the cylinder drives the pneumatic rod to retract, which in turn drives the slide to move from top to bottom. The slide then drives the heating box to move from top to bottom, and the heating box drives the fumigation chamber to move from top to bottom. Then, pushing the cylinder from right to left causes it to drive the pneumatic rod from left to right, separating the pneumatic rod from the slide. The slide then flips inside the slot of the support, quickly pouring out the rice from the fumigation chamber, thus achieving the function of quickly emptying the rice from the fumigation chamber.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that, as mentioned above, the device can only perform fumigation treatment on exposed materials. When materials are piled up, the materials piled inside may not be fumigated, which may result in external fumigation being completed while internal fumigation has not, affecting the quality of material fumigation. The overall idea is as follows: Rice fumigation and preservation equipment includes a support frame 11, a cylinder 12 is slidably installed inside the support frame 11, a pneumatic rod 13 is fixedly installed at the output end of the cylinder 12, and a slide block 14 is slidably installed on the top of the pneumatic rod 13. The bracket 11 is slidably installed inside. By activating the cylinder 12, the cylinder 12 drives the pneumatic rod 13 to retract. The pneumatic rod 13 drives the slide 14 to move from top to bottom. The slide 14 drives the heating box 15 to move from top to bottom. The heating box 15 drives the fumigation box 18 to move from top to bottom. Then, the cylinder 12 is pushed from right to left. The cylinder 12 drives the pneumatic rod 13 to move from left to right. The pneumatic rod 13 separates from the slide 14. The slide 14 flips in the groove inside the bracket 11, quickly pouring out the rice inside the fumigation box 18, thus achieving the function of quickly pouring out the rice inside the fumigation box 18.

[0029] A fumigation mechanism is fixedly installed on the top of the slide 14. The fumigation mechanism includes a heating box 15. A threaded plug 16 is threadedly installed on the side wall of the heating box 15 to facilitate the addition of water to the inside of the heating box 15.

[0030] A mounting plate 17 is fixedly installed inside the heating box 15. A fumigation box 18 is fixedly installed on the top of the mounting plate 17. A top cover 19 is sleeved on the side wall of the fumigation box 18. A rotating ring 21 is rotatably installed inside the top cover 19. A rotating shaft 22 is slidably installed inside the rotating ring 21. A stirring blade 23 is fixedly installed on the side wall of the rotating shaft 22. A motor 24 is fixedly installed on the side wall of the bracket 11. A rotating rod 25 is fixedly installed at the output end of the motor 24. A transmission assembly 26 is fixedly installed on the side wall of the rotating rod 25. The transmission assembly 26 is located away from... One end of the rotating rod 25 is fixedly installed with the rotating ring 21. The end of the transmission assembly 26 away from the rotating rod 25 is slidably installed with the rotating shaft 22. A first bevel gear 27 is fixedly installed on the top of the rotating rod 25. A second bevel gear 28 meshes with the side wall of the first bevel gear 27. A connecting rod 29 is fixedly installed on the end of the second bevel gear 28 away from the first bevel gear 27. A missing gear 31 is fixedly installed on the end of the connecting rod 29 away from the second bevel gear 28. A rack frame 32 meshes with the side wall of the missing gear 31. The bottom is rotatably mounted on the rotating shaft 22. By starting the motor 24, the motor 24 drives the rotating rod 25 to rotate counterclockwise. The rotating rod 25 drives the transmission assembly 26 to rotate counterclockwise, which in turn drives the rotating shaft 22 to rotate counterclockwise. The rotating shaft 22 drives the rotating ring 21 to rotate counterclockwise, and the rotating shaft 22 drives the stirring blade 23 to rotate counterclockwise. Simultaneously, the rotating rod 25 drives the first bevel gear 27 to rotate counterclockwise, which in turn drives the second bevel gear 28 to rotate clockwise. The second bevel gear 28 drives the connecting rod 29 to rotate clockwise, which in turn drives the missing gear 31 to rotate clockwise. The missing gear 31 drives the rack frame 32 to reciprocate up and down, which in turn drives the rotating shaft 22 to reciprocate up and down. This causes the stirring blade 23 to rotate while reciprocating up and down inside the fumigation chamber 18, ensuring that the rice inside the fumigation chamber 18 is heated more evenly during fumigation. This helps avoid hot or cold spots during fumigation, improving the quality of rice fumigation and thus achieving the function of improving rice fumigation quality.

[0031] To address the problems existing in the prior art, this utility model provides a rice fumigation and preservation device. By starting the motor 24, the motor 24 drives the rotating rod 25 to rotate counterclockwise. The rotating rod 25 drives the transmission assembly 26 to rotate counterclockwise, which in turn drives the rotating shaft 22 to rotate counterclockwise. The rotating shaft 22 drives the rotating ring 21 to rotate counterclockwise, and the rotating shaft 22 drives the stirring blade 23 to rotate counterclockwise. Simultaneously, the rotating rod 25 drives the first bevel gear 27 to rotate counterclockwise, which in turn drives the second bevel gear 28 to rotate clockwise. The second bevel gear 28 drives the connecting rod 29 to rotate clockwise, which in turn drives the missing gear 31 to rotate clockwise. The missing gear 31 drives the rack frame 32 to reciprocate up and down, which in turn drives the rotating shaft 22 to reciprocate up and down, causing the stirring blade 23 to move inside the fumigation chamber 18. While reciprocating downwards, the rotation ensures that the rice inside the fumigation chamber 18 is heated more evenly during the fumigation process, helping to avoid hot or cold spots and improving the quality of rice fumigation. By activating the cylinder 12, the cylinder 12 drives the pneumatic rod 13 to retract, which in turn drives the slide 14 to move downwards. The slide 14 then drives the heating box 15 to move downwards, which in turn drives the fumigation chamber 18 to move downwards. Then, the cylinder 12 is pushed from right to left, causing the pneumatic rod 13 to move from left to right. The pneumatic rod 13 separates from the slide 14, and the slide 14 flips inside the groove of the support 11, quickly emptying the rice from the fumigation chamber 18.

[0032] Working principle:

[0033] The first step involves starting motor 24. Motor 24 drives rotating rod 25 to rotate counterclockwise, which in turn drives transmission assembly 26 to rotate counterclockwise. Transmission assembly 26 drives rotating shaft 22 to rotate counterclockwise, which in turn drives rotating ring 21 to rotate counterclockwise. Rotating shaft 22 also drives stirring blade 23 to rotate counterclockwise. Simultaneously, rotating rod 25 drives first bevel gear 27 to rotate counterclockwise, which in turn drives second bevel gear 28 to rotate clockwise. Second bevel gear 28 drives connecting rod 29 to rotate clockwise, which in turn drives missing gear 31 to rotate clockwise. Missing gear 31 drives rack frame 32 to reciprocate up and down, which in turn drives rotating shaft 22 to reciprocate up and down. This causes stirring blade 23 to rotate while reciprocating up and down inside fumigation chamber 18, ensuring that the rice inside fumigation chamber 18 is heated more evenly during fumigation. This helps avoid hot or cold spots during fumigation, improving the quality of rice fumigation and thus achieving the function of improving rice fumigation quality.

[0034] The second step is to start the cylinder 12, which drives the pneumatic rod 13 to retract. The pneumatic rod 13 drives the slide 14 to move from top to bottom. The slide 14 drives the heating box 15 to move from top to bottom. The heating box 15 drives the fumigation box 18 to move from top to bottom. Then, the cylinder 12 is pushed from right to left, which drives the pneumatic rod 13 to move from left to right. The pneumatic rod 13 separates from the slide 14, and the slide 14 flips inside the groove of the bracket 11, quickly pouring out the rice inside the fumigation box 18, thus achieving the function of quickly pouring out the rice inside the fumigation box 18.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
