DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 , Figure 2 As shown, a screening device with a soil cleaning function comprises a supporting frame 1, on which a screening bucket 2 is movably mounted, a screening mesh 9 is fixedly connected to the bottom surface of the screening bucket 2, a reduction motor 5 is fixedly connected to one end of the supporting frame 1, an eccentric wheel 6 is fixedly connected to the output shaft of the reduction motor 5, a traction frame 7 is fixedly connected to the screening bucket 2, and the traction frame 7 and the eccentric wheel 6 are movably mounted, a No. 1 rotating rod 3 is fixedly connected to the other end of the supporting frame 1, the No. 1 rotating rod 3 is movably mounted to the supporting frame 1 through a No. 1 bearing 4, a limiting groove 8 is provided on the traction frame 7, and the traction frame 7 is movably mounted to the output shaft of the reduction motor 5 through the limiting groove 8, the reduction motor 5 drives the eccentric wheel 6 to rotate, so that the eccentric wheel 6 regularly lifts and drops the traction frame 7, and the traction frame 7 is fixedly connected to the supporting frame 1, so as to facilitate the regular vibration of the screening bucket 2 up and down, and to vibrate and screen the grains therein, so as to facilitate the soil on the outer shell of the grain to pass downward through the screening mesh 9, and the vibration can effectively prevent the screening mesh 9 from being blocked.

[0022] like Figure 1 , Figure 3 As shown, a limited height plate 11 is movably installed on the screen bucket 2, and the limited height groove 10 is fixedly connected to the two side positions in the screen bucket 2. The limited height plate 11 is movably installed in the limited height groove 10. The limited height plate 11 is clamped in the limited height groove 10, and the limited height plate 11 is pulled upward to a suitable height. The grains pass under the limited height plate 11. By limiting the height, the amount of grains passing through is controlled, so that after the grains pass through the limited height plate 11, the thickness of the screen 9 is relatively thin, which is convenient for sufficient contact with the subsequent spraying liquid and drying hot air.

[0023] like Figure 1 , Figure 4As shown, a connecting water pipe 15 is fixedly connected to the sieve bucket 2 at a side position located at the height limit plate 11, and a plurality of shunt water pipes 17 are fixedly connected to the connecting water pipe 15, and a plurality of nozzles 18 are fixedly connected to the shunt water pipe 17. A water storage tank 12 is movably installed at a lower position of the support frame 1, and a water pump 13 is fixedly connected to the side position of the water storage tank 12. The water pump 13 is fixedly connected to the connecting water pipe 15 through a No. 1 hose 14, and the connecting water pipe 15 is fixedly connected to the sieve bucket 2 through a clamp 16. A large amount of cleaning water is stored in the box 12. The cleaning water is pumped out from the water tank 12 by a water pump 13 and sent to a connecting water pipe 15 through a No. 1 hose 14. The connecting water pipe 15 is connected to a plurality of branch water pipes 17. The nozzles 18 of the branch water pipes 17 are all located on the screen 9. The cleaning water is sprayed out through the nozzles 18. The cleaning water sprayed by the plurality of nozzles 18 forms a relatively dense spraying area to rinse the passing grains, thereby facilitating a more thorough removal of the dirt on the outer shell of the grains.

[0024] like Figure 1 As shown, the sieve bucket 2 is fixedly connected with a connecting air duct 21 at a side position of the connecting water pipe 15, and a plurality of branch air ducts 22 are fixedly connected to the connecting air duct 21, and a plurality of air outlets 23 are fixedly connected to the branch air duct 22. The nozzle 18 and the air outlet 23 are both located above the screen 9, and the connecting air duct 21 is fixedly connected to the sieve bucket 2 through a clamp 16, and the connecting air duct 21 is fixedly connected to the heating blower 19 through a No. 2 hose 20. After the cereals pass through the spraying area, although the mud on the outer shell is removed, the outer shell is also soaked with liquid. If the liquid on the outer shell is not removed, the cereals are prone to mildew, etc., which easily interferes with the subsequent quality inspection and storage of the cereals. Therefore, hot air is sent into the connecting air duct 21 through the heating blower 19, and the air outlets 23 on the plurality of branch air ducts 22 spray the hot air. The hot air forms a drying area to dry the cereals passing through, thereby quickly removing moisture from the outer shell of the cereals.

[0025] It should be noted that the utility model is a screening device with a soil cleaning function. The grains with soil on the outer shell are placed in the screen bucket 2, and the reduction motor 5 is started. The output shaft of the reduction motor 5 drives the eccentric wheel 6 to rotate. The eccentric wheel 6 and the traction frame 7 are movably installed with each other. The eccentric wheel 6 provides support for the traction frame 7. With the rotation of the eccentric wheel 6, the traction frame 7 is regularly lifted and dropped up and down. The traction frame 7 is fixedly connected to one end of the screen bucket 2, and the other side of the screen bucket 2 is connected to the support frame 1 through the No. 1 rotating rod 3 and the No. 1 bearing 4. The traction frame 7 is rotatably installed, and the traction frame 7 moves up and down regularly, driving the screen bucket 2 to vibrate synchronously, so as to vibrate and screen the grains on the screen bucket 2, so that the soil on the outer shell of the grains can easily pass through the screen 9 downward. Since the soil is sticky, the effect of simple vibration screening is not good. One end of the screen bucket 2 is high and the other end is low, so that the grains roll toward the side where the nozzle 18 and the air outlet 23 are located. The vibration can effectively enhance the smoothness of the discharge and prevent the grains from stagnating and accumulating on the screen 9. A limited height plate 11 is set on the screen bucket 2. 1 moves upward to a suitable position in the height limiting groove 10, and the grains pass through the position below the height limiting plate 11. The height limiting plate 11 can effectively control the number of grains passing through, thereby reasonably controlling the thickness of the grain pile on the screen 9. The water pump 13 extracts the liquid in the water storage tank 12 and sends the liquid to the connecting water pipe 15 through the No. 1 hose 14. The connecting water pipe 15 is provided with a plurality of diversion water pipes 17, and the liquid is re-sprayed through a plurality of nozzles 18 thereon. The re-sprayed liquid forms a wider spray area, which is sprayed on the grains passing through the area. The grains in the field are rinsed to clean the soil on the outer shell of the grains, the heating blower 19 sprays hot air, and the hot air is introduced into the connecting air duct 21 through the No. 2 hose 20, and a plurality of branch air ducts 22 are arranged on the connecting air duct 21, and a plurality of air outlets 23 are arranged on the branch air duct 22 to spray the hot air, thereby forming a drying area on the screen 9 again, and the grains that have been sprayed are quickly dried, so that the grains are kept dry again, so that the soil on the outer shell of the grains can be removed more fully and thoroughly, and the cleaning effect is good.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. It is only a preferred embodiment of the utility model, and its description is more specific and detailed, but it cannot be understood as limiting the scope of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
