[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] A preferred embodiment of the grain screw conveyor device provided by this utility model is, for example... Figures 1 to 5As shown: A grain screw conveyor includes a support frame 1, an upper shell 2 fixedly connected to the top of the support frame 1, a chute 3 provided at the bottom of the upper shell 2, a slide plate 4 slidably connected inside the chute 3, a lower shell 5 fixedly connected to the bottom of the slide plate 4, a side plate 6 fixedly connected to the inner wall of the upper shell 2, screw holes 7 provided inside both the upper shell 2 and the lower shell 5, retaining rings 8 attached to the sides of both the upper shell 2 and the lower shell 5, screws 9 threadedly connected inside the retaining rings 8 and embedded in the screw holes 7, a mounting plate 10 fixedly connected to the side of the side plate 6, a servo motor 11 fixedly connected to one side of the mounting plate 10, and a conveying rod 12 fixedly connected to the output end of the servo motor 11.

[0028] In this embodiment, the side plate 6 is arranged in a circle about the center of the upper shell 2. Both the upper shell 2 and the lower shell 5 are tightly fitted with the side plate 6. By setting the side plate 6, the conveying rod 12 can continue to rotate around it when the lower shell 5 is disassembled.

[0029] In this embodiment, the centers of the upper shell 2 and the lower shell 5 are located at the same point. When the upper shell 2 and the lower shell 5 are tightly fitted together, they can form a closed structure, which can make the equipment in a sealed state and prevent the grain from flowing out from the gap.

[0030] In this embodiment, both the slide groove 3 and the slide plate 4 are "T" structures. The two ends of the slide plate 4 are flush with the two ends of the upper shell 2. Since the slide plate 4 is a "T" structure, the lower shell 5 cannot fall down when the slide plate 4 is inserted into the slide groove 3.

[0031] In this embodiment, the retaining ring 8 is fixed to the sides of the upper shell 2 and the lower shell 5 by screws 9. The slide plate 4 forms a fixed structure inside the slide groove 3 by the retaining ring 8. When installed, the retaining ring 8 can limit the two sides of the slide plate 4 to prevent the slide plate 4 from driving the lower shell 5 to move inside the slide groove 3.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the grain screw conveyor provided by this utility model is as follows: Figures 1 to 5 As shown: The top of the upper shell 2 is fixedly connected to the inlet 13, the surface of the inlet 13 is fixedly connected to the fixing plate 14, the side wall of the fixing plate 14 is fixedly connected to the fan 15, the back of the inlet 13 is fixedly connected to the collection box 16 by bolts, the inside of the inlet 13 is fixedly connected to two sets of filter screens 18, and the bottom of the lower shell 5 is fixedly connected to the discharge port 17.

[0034] In this embodiment, the two sets of filter screens 18 are positioned correspondingly, and the inlet of the collection box 16 is aligned with the filter screen 18. By setting the filter screen 18, it is possible for the wind blown out by the fan 15 to come into contact with the grain, and it can also block the grain to prevent the grain from being blown out of the equipment.

[0035] In this embodiment, the air outlet of the blower 15 corresponds to the position of the filter screen 18. By setting the blower 15, the blower 15 can blow air from inside the filter screen 18 to contact the grain, blow out the dust in the grain, and enter the collection box 16 from another set of filter screens 18, so that the dust can be collected in a concentrated manner through the collection box 16.

[0036] The working principle and usage process of this utility model are as follows: First, grain is put into the equipment through the feed inlet 13. The servo motor 11 is turned on to control the rotation of the conveyor rod 12. The conveying operation is achieved through the threads on the surface of the conveyor rod 12. When the grain falls into the feed inlet 13, the fan 15 blows air from inside the filter screen 18 to contact the grain, blowing out the dust in the grain. The dust enters the collection box 16 from another set of filter screens 18. The dust is collected in a concentrated manner through the collection box 16. Since the collection box 16 is connected to the feed inlet 13 by bolts, it can be disassembled.

[0037] By setting the lower shell 5, when it is necessary to clean the inside of the equipment, the retaining ring 8 can be disassembled by unscrewing the screw 9, and then the slide plate 4 can be pulled out to the side to remove the lower shell 5, which is convenient for cleaning the blockage inside the equipment. Since the slide plate 4 has a "T" structure, the lower shell 5 cannot fall when the slide plate 4 is inserted into the slide groove 3. In addition, the retaining ring 8 can limit the two sides of the slide plate 4 during installation to prevent the slide plate 4 from driving the lower shell 5 to move inside the slide groove 3.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
