Description

Technical Field

[0001] The utility model relates to the technical field of rice production and processing equipment, in particular to a fumigation device for imported rice at ports. Background Art

[0002] Imported rice refers to rice products that arrive at domestic ports or ports from abroad through international trade channels. As a staple food crop, rice may be affected by pests, diseases, fungal contamination, and other issues during cross-border transportation and storage. To ensure food safety and meet quarantine requirements, imported rice is typically subject to strict inspection, quarantine, and treatment procedures. Fumigation is a widely used pest control technology that effectively kills pests, insect eggs, and microorganisms in rice through the penetration of chemical gases (such as phosphine or sulfuryl fluoride), ensuring the quality and safety of imported rice and preventing the introduction of foreign pests that threaten domestic agricultural ecosystems.

[0003] Existing rice fumigation devices typically consist of a sealed container, a fumigant gas injection system, a circulating ventilation system, and detection and control equipment. Their working principle is to place imported rice in a sealed environment. By injecting a fumigant, the chemical gas is evenly distributed throughout the container, penetrating deeply into the rice crevices and packaging to kill pests and microorganisms. However, this penetration method can cause the outer layer of rice to be over-fumigated due to prolonged exposure to the gas. Therefore, the port-imported rice fumigation device was proposed to address this issue. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a fumigation device for imported rice at a port, comprising a steaming barrel 1, an air inlet pipe 2 fixedly connected to the interior of the steaming barrel 1, a fixing ring 3 fixedly connected to the interior of the steaming barrel 1, a placing cylinder 4 provided inside the steaming barrel 1, a screen 5 fixedly connected to the bottom of the placing cylinder 4, a barrel cover 6 provided on the top of the steaming barrel 1, a turning mechanism provided inside the barrel cover 6, and an adjusting mechanism provided inside the steaming barrel 1; the turning mechanism includes a motor 7, a side wall of the motor 7 fixedly connected to the top of the barrel cover 6, and the output of the motor 7 The end is fixedly connected with a driving wheel 8, the inside of the barrel cover 6 is fixedly connected with a fixed shaft 9, the bottom of the fixed shaft 9 is rotatably connected to a rotating cover 10, the top of the rotating cover 10 is fixedly connected to a driven wheel 11, the side wall of the fixed shaft 9 is fixedly connected to a bevel gear 12, the inside of the rotating cover 10 is rotatably connected to a bevel gear 2 13, the side wall of the bevel gear 2 13 is fixedly connected to a flap 14, the driving wheel 8 is meshed with the driven wheel 11, the bevel gear 12 is meshed with the bevel gear 2 13, and the driven wheel 11 is sleeved on the outside of the fixed shaft 9;

[0033] During the fumigation process, the driving wheel 8 is driven to rotate by starting the motor 7, and the driving wheel 8 further drives the rotary cover 10 to rotate synchronously under the action of the engagement between the driving wheel 8 and the driven wheel 11. When the rotary cover 10 rotates, the bevel gear 2 13 is synchronously driven to move and rotate. Due to the engagement relationship between the bevel gear 12 and the bevel gear 2 13, when the bevel gear 2 13 rotates with the rotary cover 10, the bevel gear 2 13 will rotate automatically inside the rotary cover 10, forming a multi-directional driving force, further driving the flap 14 to flip the rice inside the placement tube 4, so that the rice is continuously stirred and rolled in the tube. Through this dynamic flipping, the rice can be evenly exposed to the fumigation gas, ensuring the comprehensiveness and uniformity of the fumigation process, while avoiding the phenomenon of excessive fumigation caused by the bottom rice being in contact with the fumigation gas for a long time, improving the fumigation quality, and reducing unnecessary losses.

[0034] Reference Figure 4 The adjustment mechanism includes an air intake plate 16, the side wall of the air intake plate 16 is fixedly connected to the inside of the steam barrel 1, a rotating plate 17 is provided on the top of the air intake plate 16, and a rotating shaft 19 is fixedly connected to the bottom of the rotating plate 17. The rotating shaft 19 is rotatably connected to the inside of the air intake plate 16, and the side wall of the rotating shaft 19 is fixedly connected to a limiting ring 20. The limiting ring 20 is provided at the bottom of the air intake plate 16. A plurality of air vents 18 are provided inside the rotating plate 17, and a dial plate 21 is fixedly connected to the side wall of the rotating plate 17. A magnetic strip 22 is fixedly connected to the inside of the dial plate 21. A slide groove 15 is provided inside the steam barrel 1, and a magnet sheet is provided inside the slide groove 15. The side wall of the dial plate 21 is slidably connected to the inside of the slide groove 15.

[0035] When using the device for work, the gas required for fumigation is first sent into the interior of the steaming barrel 1 through the air inlet pipe 2. When the air intake needs to be adjusted, the operator can turn the dial plate 21 to drive the rotating plate 17 to rotate. By adjusting the dial plate 21, the number of air vents 18 on the top of the internal groove of the air inlet plate 16 will change, thereby regulating the size and speed of the gas flow. When the dial plate 21 slides from one side to the other side from the inside of the slide 15, the magnetic strip 22 inside the dial plate 21 is magnetically attracted to the magnet sheet inside the slide 15 to form a stable adsorption force, thereby accurately fixing the position of the rotating plate 17, ensuring the stability and accuracy of the adjustment, and avoiding the instability of the gas flow during operation. After the adjustment is completed, the gas moves upward through the adjusted air vents 18, and the airflow smoothly penetrates into the rice placed inside the cylinder 4.

[0036] Working principle: When the device is used, the fumigation gas is first sent into the steam barrel 1 through the air inlet pipe 2. When the air intake needs to be adjusted, the dial plate 21 can be turned to drive the rotating plate 17 to rotate, thereby changing the number of vents 18 on the top of the groove inside the air inlet plate 16. When the dial plate 21 slides from one side to the other side of the chute 15, the magnetic strip 22 inside the dial plate 21 will be magnetically attracted to the magnet sheet inside the chute 15, thereby fixing the position of the rotating plate 17. After the adjustment is completed, the gas will move upward through the vents 18, thereby fumigating the rice inside the cylinder 4.

[0037] During the fumigation process, the driving wheel 8 is driven to rotate by starting the motor 7, and under the action of the engagement between the driving wheel 8 and the driven wheel 11, the rotary cover 10 is further rotated. When the rotary cover 10 rotates, the bevel gear 2 13 is synchronously driven to move. Since the bevel gear 12 is engaged with the bevel gear 2 13, when the bevel gear 2 13 rotates with the rotary cover 10, it will also rotate inside the rotary cover 10, thereby causing the flap 14 to flip the rice inside the placement tube 4, ensuring that the rice inside the placement tube 4 is fumigated evenly, and avoiding the excessive fumigation of the rice at the bottom.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
