Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rice irradiation pest control technology, specifically relating to a rice irradiation device. Background Technology
[0002] Rice irradiation is a technology that uses radioactive rays such as gamma rays, X-rays, or electron beams to irradiate rice in order to kill insects, sterilize, and extend shelf life. The principle is to use the strong penetrating power of radiation to ionize the moisture and microorganisms in the food, thereby destroying the DNA in the substances, damaging the biological membranes, and causing cell damage. This effectively kills harmful substances such as insect eggs and bacteria on the surface of the food and inhibits the sprouting and decaying processes of the food. Irradiation equipment is required when irradiating rice.
[0003] Irradiation devices generate rays or electron beams through a ray generator or electron accelerator for irradiation. During irradiation, the penetration depth of the electron beam is affected by the size of the rice grains (typically, the electron beam penetration depth of an electron accelerator used for rice irradiation can reach 10 cm; when the rice grains are larger, the penetration depth decreases; rice is divided into indica rice and japonica rice, with indica rice typically being longer and japonica rice shorter and rounder). However, existing technologies lack components for controlling the thickness of the rice grains, resulting in a decrease in the irradiation effect on the lower rice grains when the grains are larger. Therefore, a technical measure is proposed to address the problem of the lack of components for controlling the thickness of the rice grains in existing technologies, which leads to a decrease in the irradiation effect on the lower rice grains when the grains are larger. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rice irradiation device, which aims to solve the problem that the existing technology lacks a component to control the thickness of the rice, and the irradiation effect on the lower rice is reduced when the rice grains are large.
[0006] (2) Technical solution
[0007] To address the aforementioned technical problems, this utility model provides a rice irradiation device, comprising a worktable with two symmetrically distributed side plates mounted on its upper surface. A housing is mounted on the upper part of each side plate, and an electron accelerator is mounted on the housing. A thickness control component is mounted on the upper part of the side plates. A guide plate is mounted on the end of the worktable away from the thickness control component, and the guide plate is tilted. Thanks to the thickness control component, the thickness of the rice can be controlled, allowing for adjustment of the rice thickness entering the electron accelerator according to the size of the rice grains. This ensures effective irradiation of the rice, improves insect control, enhances rice preservation, and increases practicality. Simultaneously, the threaded connection between the screw and the tube prevents the push plate from moving downwards (the threaded connection has self-locking properties; the denser the thread, the better the self-locking, i.e., the greater the friction).
[0008] Furthermore, a support frame is installed on the lower surface of the workbench.
[0009] Furthermore, a motor is installed on the side of the side plate, the motor is connected to a drive roller, the drive roller is rotatably connected to the side plate, a conveyor belt is sleeved on the outside of the drive roller, and a driven roller is sleeved on the other end of the conveyor belt, the driven roller is rotatably connected to the side plate.
[0010] Furthermore, the thickness control component includes a mounting bracket, on which multiple sets of evenly distributed mounting plates are mounted on the lower side. Bolts pass through the mounting plates, and the mounting plates are connected to the upper surface of the side plates by the bolts.
[0011] Furthermore, a threaded tube is installed through the middle of the upper surface of the mounting bracket, and a screw rod is threadedly connected to the threaded tube. A throttle handle is installed at the upper end of the screw rod.
[0012] Furthermore, a lifting plate is rotatably connected to the lower end of the screw, and two sets of symmetrically distributed limiting rods are installed on the upper surface of the lifting plate, with the limiting rods slidably connected to the mounting frame.
[0013] Furthermore, a push plate is installed on the lower surface of the lifting plate, the push plate is inclined, and the width of the lifting plate and the push plate is adapted to the two sets of side plates.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention facilitates the transfer and guidance of rice through the setting of a guide plate, which guides the rice into the next production stage.
[0017] By setting up a thickness control component, the thickness of the rice can be controlled, allowing for adjustment of the rice thickness entering the electron accelerator according to the size of the rice grains. This ensures the irradiation effect on the rice, improves the insect control effect, enhances the preservation effect of the rice, and improves practicality. At the same time, the threaded connection between the screw and the tube also prevents the push plate from moving downward (the threaded connection has self-locking properties; the denser the thread, the better the self-locking property, i.e., the greater the friction). Turning the handle moves the push plate downward. When the push plate reaches the appropriate height, turning the handle stops. When the rice comes into contact with the push plate, the push plate flattens any rice that exceeds the thickness limit, resulting in a uniform thickness of rice entering the electron accelerator.

[0024] 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.
[0025] This specific embodiment is a rice irradiation device, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 As shown, the system includes a workbench 1, with two symmetrically distributed side plates 9 mounted on its upper surface. A housing 7 is mounted on the upper part of the side plates 9, and an electron accelerator 11 is mounted on the housing 7. A thickness control component 2 is mounted on the upper part of the side plates 9. A guide plate 5 is mounted on the end of the workbench 1 away from the thickness control component 2, and the guide plate 5 is tilted. A support frame 3 is mounted on the lower surface of the workbench 1. A motor 6 is mounted on the side of the side plates 9, and the motor 6 is connected to a drive roller 4. The drive roller 4 is rotatably connected to the side plates 9. A conveyor belt 8 is fitted around the drive roller 4, and a driven roller 10 is fitted at the other end of the conveyor belt 8. The driven roller 10 is rotatably connected to the side plates 9. When irradiating rice, the motor 6 is started to drive the drive roller 4 to rotate, which in turn drives the conveyor belt 8 to rotate, which in turn drives the driven roller 10 to rotate. Then, the electron accelerator 11 is started (the electron output end of the electron accelerator 11 is inside the housing 7). Furthermore, the width of the conveyor belt 8 is adapted to the width of the electron output end of the electron accelerator 11. The electron accelerator 11 can be an MJIIy-6M2 high-frequency single-gun electron irradiation accelerator. This type of accelerator can generate high-energy electron beams and is suitable for irradiation treatment of agricultural products such as rice. Then, according to the grain size of the rice, the thickness of the rice is controlled by the thickness control component 2 (rice is divided into indica rice and japonica rice. Indica rice is usually longer, while japonica rice is shorter and rounder. When irradiating indica rice, the thickness of the rice should be shallower). The rice is transported to the surface of the conveyor belt 8 through an external transmission mechanism. The conveyor belt 8 transports the rice to the thickness control component 2, which controls the thickness. Then, the rice undergoes irradiation treatment through the electron accelerator 11 (irradiation treatment involves a certain amount of radiation, and staff should take protective measures or use remote control). Subsequently, the rice is guided into the next production stage under the action of the guide plate 5.
[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the thickness control component 2 includes a mounting frame 202. Multiple sets of evenly distributed mounting plates 201 are mounted on the lower side of the mounting frame 202. Bolts 207 pass through the mounting plates 201, connecting them to the upper surface of the side plate 9. A threaded tube 205 is installed through the middle of the upper surface of the mounting frame 202, threadedly connected to a screw rod 204. A handle 203 is mounted on the upper end of the screw rod 204, and a lifting plate 208 is rotatably connected to the lower end of the screw rod 204. Two sets of symmetrically distributed limit rods 206 are mounted on the upper surface of the lifting plate 208, slidingly connected to the mounting frame 202. A push plate 209 is mounted on the lower surface of the lifting plate 208, and the push plate 209 is inclined. The widths of the lifting plate 208 and the push plate 209 are adapted to the two sets of side plates 9. Rotating the handle 203 drives the screw 204 to move downward along the screw tube 205 (when irradiating indica rice, the thickness of the rice should be shallower). The downward movement of the screw 204 drives the lifting plate 208 to move downward. The downward movement of the lifting plate 208 drives the limit rod 206 to slide downward along the mounting frame 202. The downward movement of the lifting plate 208 drives the push plate 209 to move downward. When it moves to a suitable height (which needs to be adjusted according to the specific size of the rice), stop rotating the handle 203. When the rice comes into contact with the push plate 209, the push plate 209 flattens the rice that exceeds the thickness, so that the thickness of the rice entering the electron accelerator 11 is uniform.
[0027] Working principle: During the actual irradiation treatment of rice, the starting motor 6 drives the active roller 4 to rotate, which in turn drives the conveyor belt 8 to rotate, which in turn drives the driven roller 10 to rotate. Then, the electron accelerator 11 is activated (the electron output end of the electron accelerator 11 is inside the housing 7, and the width of the conveyor belt 8 is adapted to the width of the electron output end of the electron accelerator 11; the electron accelerator 11 can be an MJIIy-6M2 high-frequency single-gun electron irradiation accelerator, which can generate a high-energy electron beam suitable for irradiation treatment of agricultural products such as rice). Subsequently, based on the grain size of the rice, the thickness control component 2... The thickness of the rice is controlled (rice is divided into indica rice and japonica rice; indica rice is usually longer, while japonica rice is shorter and rounder. When irradiating indica rice, the thickness of the rice should be shallower). The rice is transported to the surface of conveyor belt 8 through an external transmission mechanism. Conveyor belt 8 transports the rice to thickness control component 2, which controls the thickness. The rice then undergoes irradiation treatment through electron accelerator 11 (irradiation treatment involves radiation, so staff must take protective measures or use remote control). Subsequently, the rice is guided into the next production stage by guide plate 5. The guide plate 5 facilitates the transmission and guidance of the rice.
[0028] The thickness control component 2 operates as follows: rotating the handle 203 drives the screw 204 downward along the screw tube 205 (when irradiating indica rice, the rice thickness should be shallower). The downward movement of the screw 204 causes the lifting plate 208 to move downward. The downward movement of the lifting plate 208 causes the limit rod 206 to slide downward along the mounting frame 202. The downward movement of the lifting plate 208 causes the push plate 209 to move downward. When it reaches a suitable height (which needs to be adjusted according to the specific size of the rice), rotating the handle 203 stops. When the rice contacts the push plate 209, the push plate... Plate 209 flattens rice grains that exceed the required thickness, ensuring a uniform thickness of rice entering the electron accelerator 11. The thickness control component 2 allows for precise control of the rice thickness, enabling adjustments based on grain size to ensure optimal irradiation, improved pest control, and enhanced preservation, thus increasing practicality. Simultaneously, the threaded connection between screw 204 and screw tube 205 prevents the pusher plate 209 from moving downwards (the threaded connection is self-locking; the denser the thread, the better the self-locking, i.e., the greater the friction).
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
