[0053] Working principle of the present invention:

[0054] When the present invention is in use, first add grains to the feed hopper 3. After the grains are added, turn on the conveyor belt 4 so that the conveyor belt 4 can effectively transport the grains. In the process of transporting the grains, control the vibration rod 31 to vibrate, and the vibration will also be transmitted to the feed hopper 3 through the mounting plate, which is conducive to promoting the grains in the feed hopper 3 to fall and avoid the grains being stuck at the bottom of the feed hopper 3. After the grains fall on the conveyor belt 4, the conveyor belt 4 will transport the grains toward the direction of the vibrating screen 9. When the grains pass through the vibrating rod 31, the vibration of the vibrating rod 31 will be applied to the grains. On the one hand, the grains that have agglomerated in the grains during the storage process can be broken up. On the other hand, the height of the vibrating rod 31 can also be used to quantitatively limit the grains transported by the conveyor belt 4, which is conducive to avoiding the inability of the vibrating screen 9 to effectively screen the grains due to excessive grain transportation per unit time.

[0055] After the grains fall on the vibrating screen 9, the smaller grains and insect eggs will fall on the heating inclined plate 17 along the sieve holes 22. The agglomerated grains will be scattered into small grains after being broken up by the vibrating rod 31. When the small grains fall on the vibrating screen 9, the vibration of the vibrating screen 9 is used to effectively screen the grains. At the same time, during the vibration of the vibrating screen 9, the micro spring 23 on the top of the vibrating screen 9 will be driven to vibrate, and the micro spring 23 can further break up the grains that have been agglomerated into small clusters. On the one hand, it is helpful to prevent the insect eggs from being wrapped by the grains, resulting in the inability to effectively discharge the insect eggs. On the other hand, after the grains are further broken up, it is helpful for the vibrating screen 9 to screen down the small grains. Secondly, when the grains that have been agglomerated into small clusters are broken up, the smaller insect eggs wrapped inside them will fall on the heating inclined plate 17 along the sieve holes 22. It should be noted that the vibrating screen 9 is driven to work by turning on the vibration motor 27.

[0056] As the vibrating screen 9 works, the inclined surface of the triangular partition plate 24 set on the top of the vibrating screen 9 will transport the grains to a position close to the sampling and collecting box 7. In this process, the first fan 5 is turned on, and the vibrating screen 9 will vibrate the small particles in the grains. The greater the mass of the grain, the lower the vibration height of the vibrating screen 9. Through the vibration of the vibrating screen 9, the insect-infested grains can be vibrated to a higher height than that of conventional grains, and the insect-infested grains will be vibrated to the top of the side wall of the sampler body 1. After the first fan 5 is turned on, an airflow will be formed above the sampler body 1. When the insect-infested grains come into contact with the airflow, they will be blown into the transfer box body 6 by the airflow, and then the insect-infested grains will be effectively collected through the transfer box body 6.

[0057] After the insect-infested grains enter the transfer box body 6, a part of the airflow will also enter the transfer box body 6. After entering the transfer box body 6, the airflow will pass through the spoiler 28, and then be discharged into the outside atmosphere through the second filter 10. The insect-infested grains will fall on the impurity removal inclined plate 29 located at the bottom of the transfer box body 6 under the action of the spoiler 28. After the vibration of the vibration motor 27, part of the vibration will also be transmitted to the transfer box body 6, so that the insect-infested grains can fall along the impurity removal inclined plate 29 under the action of gravity and part of the vibration force emitted by the vibration motor 27, and finally be effectively collected through the impurity collection box 12.

[0058] As the vibrating screen 9 continues to work, the grains will fall on one end of the sampler body 1 close to the sampler collection box 7. After the grains fall on this end of the sampler body 1, they will fall under the action of gravity and then fall on the triangular plate 13. Guided by the triangular plate 13, the grains can be effectively dispersed. By turning on the second fan 18 and using the second fan 18 to blow the grains, the grains with large mass will fall on the side of the sampler collection box 7 close to the sampler body 1, while the grains with smaller mass will fall on the end of the sampler collection box 7 away from the sampler body 1. The grains of different masses are collected through the multiple compartments opened on the sampler collection box 7, thereby achieving the purpose of effectively sampling the grains of different masses.

[0059] In the process of putting the grains into the feed hopper 3, the heating inclined plate 17 is turned on to increase the temperature of the heating inclined plate 17. After the temperature of the heating inclined plate 17 is increased, on the one hand, the insect eggs falling on the heating inclined plate 17 can be heated, so that the insect eggs lose their activity under the action of heat, thereby achieving the purpose of killing the insect eggs. On the other hand, by utilizing the heating of the heating inclined plate 17, the heat can also be conducted along the air to the grains above the vibrating screen 9 to dry the grains above the vibrating screen 9. In the process of the grains falling along the triangular plate 13, the second fan 18 will draw air from the chamber below the heating inclined plate 17 inside the sampler body 1, and the airflow will be heated by the heating inclined plate 17 to increase the temperature of the airflow. After the temperature of the airflow increases, it will blow on the grains sliding down from the triangular plate 13, which can further promote the drying of the grains.

[0060] The vibration of the vibrating screen 9 will also be transmitted to the heating inclined plate 17, thereby shaking off the grains on the heating inclined plate 17 into the water tank 2. After falling into the water tank 2, the grains will come into contact with the water in the water tank 2, while the grains and insect eggs among the smaller grains will float on the water surface. At this time, by turning on the water pump 11, the water pump 11 draws water from the bottom of the filter screen 20, and then transports it to the horizontal groove 25, and finally sprays it on the water tank 2 through the nozzle 26. After being sprayed by the nozzle 26, the water flow will fall into the soaking pool, and the water in the soaking pool will increase, while the water in the purification pool will become less under the extraction of the water pump 11, so that the water flow can flow in the water tank 2, and the insect eggs floating on the water surface and the smaller grains infested by insects can be effectively filtered through the filter screen 20.

[0061] The whole grains with smaller particles will be soaked directly in the soaking tank. After soaking, they can be cleaned and processed accordingly, such as being processed into poultry feed.

[0062] When the grains fall into the sampling collection box 7 through the triangular plate 13, the slider 15 is controlled to slide on the slide rail 16, thereby driving the sampling box 14 to move to the side of the triangular plate 13 away from the sampler body 1, and sampling is performed on the grains after screening. The samples are used to determine whether the insect eggs and insect-infested grains in the grains have been screened thoroughly.

[0063] Through the screening of the vibrating screen 9, the small grains and insect eggs in the grains can be preliminarily sampled, and the grains that are clumped into small clumps can be broken up by the micro springs 23. After the preliminary screening, the larger grains still on the vibrating screen 9 can be further sampled by the second fan 18, which effectively ensures the diversification of the sampling. After the small grains fall onto the heating inclined plate 17, they can be directly soaked, and the insect eggs can be filtered during the soaking process, which is beneficial to avoid the occurrence of insect eggs in the grains in the subsequent processing of the small grains into feed. Secondly, the water flow sprayed by the nozzle 26 can also reduce the dust on the grains falling from the heating inclined plate 17.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
