The bottom of the feeding box is bolted to the top of the fixing block.

[0004] Existing technology involves pouring grain into the inside of the feeding box and then moving the baffle by the handle to control the feeding speed. When the feeding speed of the feeding box is too fast, the grain passes quickly through the air outlet of the bellows, and some impurities are mixed in between the grains. The wind is not enough to separate the impurities, resulting in incomplete removal of impurities.

[0005] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] A compound grain cleaning device, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the impurity removal structure is located above the main body 1 of the device. A hopper 5, capable of holding and rotating grain, is positioned above the main body 1. A discharge pipe 6, which disperses and regulates the grain flow, is located on one side of the hopper 5. A cleaning box 3 is located on the top surface of the main body 1, and a bellows 10 is located on one side of the cleaning box 3. The impurity removal structure also includes baffles 16, a rotating shaft 17, and rotating pipes 18. One end of the discharge pipe 6 extends into the cavity of the hopper 5 and is fixedly connected to the hopper 5. The other end of the discharge pipe 6 slopes downwards. Two baffles 16 are located within the cavity of the discharge pipe 6. A rotating shaft 17 is fixedly mounted on one side of one baffle 16, and two rotating pipes 18 are fixedly mounted on one side of the other baffle 16. The rotating shaft 17 is rotatably connected to the thinner wall surface. The two baffles 16 are circular in shape and fit the cavity of the discharge pipe 6. The impurity removal structure also includes a round block 19 and a square block 20. One end of the rotating shaft 17 and one end of the upper rotating tube 18 extend out of the discharge pipe 6. A round block 19 is fixed on the wall surface of the rotating shaft 17 and the rotating tube 18. Both round blocks 19 are fixedly connected to a square block 20. The impurity removal structure also includes an adjusting rod 14, an insert rod 15 and a baffle 16. Several insertion holes 13 are opened on the wall surface of the discharge pipe 6. Both ends of the adjusting rod 14 are fixedly connected to a square block 20. The other end of the insert rod 15 passes through the adjusting rod 14 and is inserted into the insertion hole 13. The insert rod 15 is slidably connected to the adjusting rod 14.

[0027] Pour the grains to be cleaned into the hopper 5, move the insert rod 15, and insert one end of the adjusting rod 14 into the corresponding insertion hole 13 through the insert rod 15. The position of the adjusting rod 14 moves the two square blocks 20 and the two round blocks 19. The rotating shaft 17 and the rotating tube 18 rotate, and the two baffles 16 rotate, dividing the outlet of the discharge pipe 6 into two parts. Adjust the outlet size as needed. When the grains fall from the two outlets, they are divided into two parts, and the grains in the middle can also come into contact with the air, so that impurities can be cleaned more thoroughly.

[0028] A compound grain cleaning device, such as Figure 1 , Figure 2 and Figure 3 As shown, the device body 1 is set above the ground. The impurity removal structure also includes a support box 4, a first gear 11, and a second gear 12. The support box 4 is fixedly connected to one side of the cleaning box 3. The bottom end of the hopper 5 extends into the support box 4 and is rotatably connected to the support box 4. A second gear 12 is fixedly installed at the end of the hopper 5. The second gear 12 meshes with the insertion hole 13, and both the second gear 12 and the insertion hole 13 are rotatably connected to the inner bottom surface of the support box 4. A collection box 7 is provided on the bottom surface of the cleaning box 3. A drawer box 8 is provided on one side of the collection box 7. A stepper motor 21 is fixedly installed on the bottom surface of the support box 4. The stepper motor 21 is fixedly connected to one side of the first gear 11 through a coupling. A drop outlet 9 is opened on the top surface of the collection box 7. A blower box 10 is fixedly installed on one side of the cleaning box 3. The air outlet of the blower box 10 faces the drop outlet 9.

[0029] Turn on the power to the stepper motor 21 and set its rotation angle to 90 degrees. This will drive the first gear 11 to rotate, which in turn drives the second gear 12 to rotate. The second gear 12 then drives the hopper 5 to rotate. The grain in the hopper 5 will exit through the rotating discharge pipe 6 and be evenly distributed. Turn on the power to the bellows 10. The bellows 10 will blow air onto the distributed grain, blowing away any obstructed impurities and sending them into the drop outlet 9, where they will fall into the collection box 7. Once the box is full, open the drawer 8 to empty the impurities. The grain with the impurities removed will fall into the device body 1. The device body 1 will then further sieve the grains by size. The device body 1 has two sieve boxes. The upper sieve box has sieve holes that can filter larger grains. Grains with suitable sieve holes can be used. Both sieve boxes are elastically connected to the support frame. The two sieve boxes are tilted as a whole, and they shake and sieve as the grain falls.

[0030] The working principle of this utility model is as follows: The grain to be cleaned is poured into the hopper 5. The insert rod 15 is moved, inserting one end of the adjusting rod 14 into the corresponding insertion hole 13. The movement of the adjusting rod 14 moves two square blocks 20, which in turn moves two round blocks 19. The rotating shaft 17 and rotating tube 18 rotate, and the two baffles 16 rotate, dividing the outlet of the discharge pipe 6 into two parts. The outlet size is adjusted as needed. When the grain falls from the two outlets, it is divided into two parts, allowing the grain to come into contact with the air, thus cleaning impurities more thoroughly. The stepper motor 21 is then turned on. The source is set to rotate stepper motor 21 at a rotation angle of 90 degrees, which drives the first gear 11 to rotate. The first gear 11 drives the second gear 12 to rotate, and the second gear 12 drives the hopper 5 to rotate. The grain in the hopper 5 is discharged from the rotating discharge pipe 6 and the grain is evenly scattered. The power of the bellows 10 is turned on, and the bellows 10 blows air towards the scattered grain, which can blow away the obscured impurities and blow the impurities into the drop port 9, which falls into the collection box 7. When it is full, the drawer 8 is opened to pour out the impurities. The grain with impurities removed falls into the device body 1, and the device body 1 screens the grain particles again.
