[0024] Therefore, the wheat seeds are first poured into the distributing mechanism 7 through the feeding hopper 5, at the same time, the driving mechanism 2 controls the distributing mechanism 7 to swing left and right, the distributing mechanism 7 is used to screen out the larger sand and stone, and the screening efficiency of the distributing mechanism 7 is improved, then the wheat seeds screened once are also shaken out and fall on the guide filter plate 9 when the distributing mechanism 7 swings left and right, then the air blower 4 blows the strong air flow to the filter screen structure of the guide filter plate 9, the dust and sludge in the wheat seeds rolling and falling on the filter screen structure of the guide filter plate 9 are blown away, the screening effect of the guide filter plate 9 is improved, and the wheat seeds roll along the guide filter plate 9 as much as possible to enter the discharging hopper 10 and leave, so that the wheat seeds are prevented from staying in the box body 1.

[0025] Specifically, as shown in Figure 2 and Figure 5 , the driving mechanism 2 comprises a driving motor 21, a rack 27 and a transmission rod 28, the driving motor 21 is fixedly connected to the left end of the box body 1, the output end of the driving motor 21 is provided with a rotating disc 22, the front end of the rotating disc 22 is provided with a poking rod 23, the poking rod 23 is slidingly connected to the rotating disc 22, the poking rod 23 can be moved outward from the center of the rotating disc 22 to adjust the left and right moving distance of the rack 27, so as to adjust the rotation angle of the straight gear 26, and then adjust the swing amplitude of the distributing mechanism 7, so that the mixed sand and stone of the wheat seeds are not directly shaken and fallen to the right part of the inner cavity of the box body 1 when the distributing mechanism 7 swings to screen the wheat seeds, the transmission rod 28 is rotationally connected to the front end of the box body 1, the rear end of the transmission rod 28 extends into the box body 1 and is rotationally connected to the inner wall on the rear side of the box body 1, the front end of the transmission rod 28 is provided with the straight gear 26, and the straight gear 26 is engaged with the rack 27, the rack 27 is horizontally arranged on the upper side of the straight gear 26, the left end of the rack 27 is provided with a push-pull rod 25, and the push-pull rod 25 is slidingly connected to the left end of the rack 27. Figure 2 As can be seen, in actual work, the U-shaped limiting workpiece can be used to limit the position of the push-pull rod 25, so that the push-pull rod 25 can only move left and right, and cannot move up and down and deflect, the left end of the push-pull rod 25 is provided with a rectangular frame one 24, and the rectangular frame one 24 is sleeved on the outer side of the poking rod 23, the length of the rectangular frame one 24 is greater than the diameter of the rotating disc 22, and the inner side width of the rectangular frame one 24 is equal to the diameter of the poking rod 23, so that the poking rod 23 can continuously drag the rectangular frame one 24 and the push-pull rod 25 to move left and right when the poking rod 23 moves in a circular trajectory by rotating the rotating disc 22;

[0026] Therefore, the driving motor 21 first works to control the rotating disc 22 to rotate, then the rotating disc 22 controls the poking rod 23 to move in a circular trajectory to continuously drag the rectangular frame one 24 and the push-pull rod 25 to move left and right, so that the rack 27 can move left and right to drive the engaged straight gear 26 to rotate, and finally the straight gear 26 drives the transmission rod 28 to rotate to control the distributing mechanism 7 to swing left and right.

[0027] Specifically, as shown in Figure 3 and Figure 6 The distribution mechanism 7 includes a base 71, which is sleeved on the outside of the transmission rod 28 and fixedly connected with the transmission rod 28, the upper end of the base 71 is provided with a distribution box 72, the left part and the top part of the distribution box 72 are open structures, so that the screened wheat seeds can leave from the left part of the distribution box 72 when the base 71 deflects to the left, the upper end of the distribution box 72 is provided with a rectangular frame two 73, the inner side bottom of the rectangular frame two 73 is provided with a screening net 74, the mesh size of the screening net 74 is greater than the size of the wheat seeds, so that the wheat seeds can normally pass through the screening net 74 and enter the inner side of the distribution box 72;

[0028] Therefore, the wheat seeds mixed with impurities first fall on the screening net 74 at the bottom of the rectangular frame two 73, and then, with the swinging of the base 71, the wheat seeds are accelerated to enter the distribution box 72, and at the same time, the stones with a volume greater than the wheat seeds are screened out and wait for subsequent cleaning.

[0029] Further, the height of the right side wall of the rectangular frame two 73 is equal to half of the height of the left side wall of the rectangular frame two 73, so that after the screening of the wheat seeds, the stones remaining in the rectangular frame two 73 can be dropped out by expanding the swinging range of the distribution mechanism 7, and then discharged through the inclined plate 8 and the discharge chute 11.

[0030] Further, the right end of the box body 1 is provided with a triangular distribution plate 6, which is located between the air blower 4 and the inclined plate 8, the right end of the triangular distribution plate 6 is located on the right side of the air blower 4, so as to avoid the discharged stones from directly falling on the air blower 4 and causing damage to the air blower 4.

[0031] Therefore, the specific embodiment of the present application is:

[0032] Firstly, the distance between the reducing knob 23 and the center of the rotating disc 22 is adjusted, then the wheat seeds are poured into the distributing mechanism 7 through the feeding hopper 5, and the driving motor 21 and the air blower 4 are started, the driving motor 21 is controlled to drive the rotating disc 22 to rotate, then the rotating disc 22 drives the rectangular frame 24 and the push-pull rod 25 to move left and right by moving in a circular track through the control of the knob 23, so that the rack 27 can move left and right to drive the meshed spur gear 26 to rotate, then the spur gear 26 drives the transmission rod 28 to rotate to control the base 71 to swing left and right, so that the wheat seeds accumulated on the screening net 74 can move and fall into the distributing box 72, and the sand and stones with large volume are screened out, and the wheat seeds falling into the distributing box 72 can fall from the left opening of the distributing box 72 to the inclined part of the guide filter plate 9 under the swinging of the distributing box 72, at this time, the air blower 4 blows strong air flow to the filter screen structure of the guide filter plate 9, blows away the dust and sludge in the wheat seeds rolling and falling on the filter screen structure of the guide filter plate 9, improves the screening effect of the guide filter plate 9, and makes the wheat seeds roll into the discharging hopper 10 as far as possible, so as to avoid the wheat seeds staying in the box 1.

[0033] After the screening is completed, the distance between the knob 23 and the center of the rotating disc 22 is enlarged, then the above steps are repeated, so that the swinging range of the distributing mechanism 7 is enlarged, the sand and stones staying on the screening net 74 can fall from the right side of the screening net 74, and finally the sand and stones are discharged through the inclined plate 8 and the discharging chute 11.

[0034] It should be noted that the specific installation method, circuit connection mode and control method of the driving motor 21 in the utility model are all conventional designs, and the utility model will not be described in detail.
