[0030] The screw conveying mechanism 23 is an existing mechanism, which includes a driving motor, a driving shaft and a spiral blade. The driving motor is fixedly installed at the left position of the top of the rear side of the box body 1. The output end of the driving motor passes through the rear part of the box body 1 and is fixedly installed with a driving shaft. The outer wall of the driving shaft is fixedly installed with a plurality of spiral blades arranged in a linear manner, and the plurality of spiral blades are all located in the conveying cylinder 22.

[0032] The output end of the motor 25 can drive the turntable 26 to rotate, so that the driving plate 29 can slide back and forth on the slide bar 28 through the pulling or pushing of the rotating rod 27 .

[0033] like Figure 4 and Figure 5 As shown, three linearly arranged racks 210 are fixedly installed at the lower end of the driving plate 29, the bottom of the inner walls of the three lower material covers 24 are rotatably connected to the rotating shafts 211 that pass through the left parts of the three lower material covers 24, the outer walls of the three rotating shafts 211 are fixedly installed with adjusting plates 212, the left parts of the outer walls of the three rotating shafts 211 are fixedly sleeved with gears 213, and the outer surfaces of the three gears 213 are meshed with the lower ends of the three racks 210.

When the three adjustment plates 212 rotate clockwise by a certain angle, the three material lowering covers 24 can be closed, and when the three adjustment plates 212 rotate counterclockwise by a certain angle, the three material lowering covers 24 can be opened.

[0035] like Figure 6 and Figure 7As shown, the wind screen collecting assembly 3 includes a fixed frame 31, a mounting groove is provided at the left bottom of the box body 1, the upper and lower ends of the fixed frame 31 are fixedly installed with the upper and lower parts of the inner wall of the mounting groove, a through groove is provided at the upper left part of the fixed frame 31, a filter screen 32 is movably connected to the inner wall of the through groove, a limit strip 33 is fixedly installed at the lower end of the filter screen 32, a fixed plate 34 is fixedly installed at the bottom of the inner wall of the fixed frame 31, a card slot is provided at the upper end of the fixed plate 34, and the lower end of the limit strip 33 is card-engaged with the inner wall of the card slot.

[0036] A top plate is fixedly mounted on the upper end of the filter screen 32, and the top plate can block the through slot to prevent impurities from leaking out of the through slot. When the filter screen 32 is installed, the filter screen 32 can be fixed by inserting the limit strip 33 into the slot, which has a simple structure and is easy to operate.

[0037] like Figure 2 and Figure 6 As shown, a blower 35 is fixedly installed on the right bottom of the box body 1, the output end of the blower 35 passes through the right part of the box body 1 and is fixedly installed with an air supply pipe 36, a plurality of linearly arranged blowing heads 37 are fixedly installed on the left part of the outer wall of the air supply pipe 36, and the plurality of blowing heads 37 are located on the right side of the filter screen 32, an inclined guide plate 39 is fixedly installed on the right bottom of the fixed frame 31, and a discharge trough 38 is opened on the right bottom of the box body 1, and the discharge trough 38 is located on the right side of the guide plate 39.

[0038] The blower 35 is an existing mechanism, and its internal rotor rotates at high speed. The volume between the blades on the rotor changes due to its rotation. During the high-speed rotation, air is sucked in from the input end of the blower 35. The sucked air is compressed by the blades and finally spit into the air delivery pipe 36. Then, a number of air blowing heads 37 act on the fallen seeds to separate the seeds from impurities. Dust and impurities remain on the filter 32, and some larger dead leaves fall between the fixed frame 31 and the fixed plate 34, while clean seeds flow out of the discharge trough to the outside through the guide plate 39. A transmission mechanism is generally set on the right side of the box 1 for conveying seeds.

[0039] like Figure 7 As shown, the cleaning assembly 4 includes an adjusting screw 41, the outer wall of the adjusting screw 41 is threadedly connected to the inner wall of the middle left side of the fixed plate 34, the right end of the adjusting screw 41 is rotatably connected to a scraper 42, and the lower end of the scraper 42 is slidably connected to the right position of the bottom of the inner wall of the fixed frame 31.

[0040] By rotating the adjusting screw 41, the adjusting screw 41 drives the scraper 42 to move rightward through the threaded connection with the fixing plate 34. The scraper 42 can scrape off the impurities in the fixing frame 31, and the impurities flow into the outside through the guide plate 39.

[0041] like Figure 7As shown, the left front and rear parts of the fixed plate 34 are slidably connected with limit rods 43 that penetrate the left part of the fixed plate 34 , and the right ends of the two limit rods 43 are fixedly connected to the left front and rear parts of the scraper 42 .

[0042] The two limiting rods 43 have a limiting effect on the movement of the scraper 42 .

[0043] The working principle of the utility model is as follows: the screw conveying mechanism 23, the motor 25 and the blower 35 are started, the seeds enter the conveying cylinder 22 from the feed hopper 21, and the screw conveying mechanism 23 conveys the materials to the three material discharge covers 24. At the same time, the output end of the motor 25 drives the turntable 26 to rotate, so that one end of the rotating rod 27 rotates around the turntable 26, and the other end pushes or pulls the driving plate 29 to move back and forth, so that the three gears 213 drive the three adjustment plates 212 to rotate by meshing with the corresponding racks 210, and the three adjustment plates 212 thereby realize the opening and closing of the three material discharge covers 24, so that the materials in the conveying cylinder 22 are evenly dispersed and discharged. After the blower 35 inhales the air, it is compressed and sprayed into the air delivery pipe 36, and then a number of blowing heads 37 act on the surface of the material, so that the falling material is fully in contact with the wind, the seeds are separated from the impurities, the dead leaves and the shriveled seeds fall into the fixed frame 31, and the clean seeds flow into the outside world from the discharge trough 38 along the guide plate 39.

[0044] When the filter screen 32 needs to be cleaned later, the filter screen 32 is pulled to make the limit bar 33 leave the slot on the fixed plate 34, and the filter screen 32 can be pulled out from the through slot. After cleaning the filter screen 32, it is reinserted into the fixed frame 31. Then, the adjusting screw 41 is rotated, and the adjusting screw 41 drives the scraper 42 to move by being threadedly connected with the fixed plate 34. The scraper 42 pushes the impurities in the fixed frame 31 onto the guide plate 39 through the limiting action of the two limit rods 43. Due to the inclined setting of the guide plate 39, the impurities flow out from the discharge chute 38.

[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
