Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a dust removal device for a grain repetitive cleaning machine, comprising:

[0035] The grain cleaning machine body 1 is equipped with a dust removal mechanism. It should be noted that the dust removal mechanism is used to remove dust from the grain.

[0036] The dust removal mechanism includes a conveying cylinder 2, a material pipe 4, a diversion plate 5, a dust suction head 6, a rotating pipe 8, an agitator 9, a power motor 10, a power shaft 11, a gear one 12, a gear two 13, a rubber ball 14, and a conveying auger 15;

[0037] The conveying cylinder 2 is fixedly installed on the top of the grain cleaning machine body 1, the material pipe 4 is fixedly installed on the top inner wall of the grain cleaning machine body 1, the diversion plate 5 is fixedly installed inside the material pipe 4, and the dust suction head 6 is fixedly installed on the grain cleaning machine body 1 and the material pipe 4. It should be noted that the dust suction head 6 is connected to an external vacuum cleaner.

[0038] The stirring blade 9 is fixedly installed inside the rotating tube 8. The output end of the power motor 10 is fixedly connected to the power shaft 11. Gear 12 is fixedly sleeved on the outside of the power shaft 11, and gear 2 13 is fixedly sleeved on the outside of the rotating tube 8. Gear 12 and gear 2 13 mesh with each other. Rubber ball 14 is installed on the power shaft 11, and conveying auger 15 is fixedly installed on the top of the power shaft 11.

[0039] Through the aforementioned dust removal mechanism, grain is added into the conveying cylinder 2 through the grain feeding pipe. The power motor 10 is started, and the power shaft 11 drives the conveying auger 15 to rotate, so that the grain is evenly fed into the feed pipe 4 through the lifting guide 3. The grain hits the two guide plates 5 in sequence, which causes dust to be raised. The dust suction head 6 can suck up the dust. The power shaft 11 drives the gear 12 to rotate, the gear 2 drives the rotating pipe 8 to rotate, and the rotating pipe 8 drives the stirring blade 9 to rotate. The stirring blade 9 can stir the falling grain, further raising the dust. The dust suction head 6 can suck up the dust. At the same time, the power shaft 11 drives the rubber ball 14 to rotate. The rubber ball 14 hits the feed pipe 4, causing the feed pipe 4 to vibrate, which in turn causes the grain to vibrate, improving the dust raising effect and thus improving the dust removal effect. This can ensure the surrounding environment during grain cleaning.

[0040] Specifically, a support plate 7 is fixedly installed inside the grain cleaning machine body 1, a rotating tube 8 is rotatably installed on the support plate 7, a power motor 10 is fixedly installed at the bottom of the support plate 7, the top of the rotating tube 8 is in contact with the material pipe 4, and a guide tube 3 is fixedly installed between the conveying cylinder 2 and the grain cleaning machine body 1. It should be noted that this is to facilitate the conveying of grain.

[0041] Specifically, the diversion plate 5 is set at an angle. It should be noted that the grains hit the two diversion plates 5 in sequence, which will cause dust to be generated.

[0042] Specifically, a support plate 16 is fixedly installed inside the grain cleaning machine body 1. Below the support plate 16 are a first gravity separation platform 17, a second gravity separation platform 18, a connecting rod 19, a turntable 20, and a crank 21. The first gravity separation platform 17 and the second gravity separation platform 18 are rotatably connected to the lower part of the support plate 16 via the connecting rod 19. The turntable 20 is rotatably connected to the second gravity separation platform 18 via the crank 21. A drive motor is fixedly installed on the rear side of the grain cleaning machine body 1, and the output end of the drive motor is fixedly connected to the turntable 20. A discharge hole 1 is opened on the side of the grain cleaning machine body 1, and a discharge plate is fixedly installed inside the discharge hole 1. The cleaning machine body 1 has two discharge holes on both sides. It should be noted that when the drive motor is started, the turntable 20 rotates. Then, through the cooperation of the crank 21 and the connecting rod 19, the first gravity separation platform 17 and the second gravity separation platform 18 move back and forth to clean the grain. Moldy, rotten and other low-density shriveled grains move to the upper layer of the material and to the lowest point, and are finally discharged from the first discharge hole. The grains move to the higher side through the gravity screen and fall to the second gravity separation platform 18. The grains are selected by the gravity screen on the second gravity separation platform 18. The grains are discharged from the two discharge holes 2 according to their different sizes.

[0043] Specifically, a grain feeding pipe is fixedly installed at the top of the conveying cylinder 2, and the conveying auger 15 is rotatably installed on the conveying cylinder 2. It should be noted that this facilitates the uniform conveying of grain.

[0044] Specifically, the rubber ball 14 is located on one side of the feed tube 4, which is to facilitate striking the feed tube 4.

[0045] Working principle:

[0046] S1: Grains are added into the conveying cylinder 2 through the grain feeding pipe. The power motor 10 is started, and the power motor 10 drives the power shaft 11 to rotate. The power shaft 11 drives the conveying auger 15 to rotate, so that the grains are evenly added into the feed pipe 4 through the lifting guide 3. The grains hit the two guide plates 5 in sequence, which will cause dust to be generated. The dust suction head 6 can suck up the dust.

[0047] S2: The power shaft 11 drives the gear 12 to rotate, the gear 12 drives the gear 2 13 to rotate, the gear 2 13 drives the rotating tube 8 to rotate, the rotating tube 8 drives the stirring blade 9 to rotate, the stirring blade 9 can stir the falling grains, further causing the dust to rise, and the dust suction head 6 can suck up the dust.

[0048] S3: The power shaft 11 simultaneously drives the rubber ball 14 to rotate. The rubber ball 14 strikes the material pipe 4, causing the material pipe 4 to vibrate, which in turn causes the grain to vibrate, making the dust fully rise, thereby improving the dust removal effect and ensuring the surrounding environment during grain cleaning.
