[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a dustproof structure for a low-profile small crop harvester, including a harvester discharge pipe 1, an outlet 3 integrally connected to the bottom side of the harvester discharge pipe 1, a fixing frame 4 fixedly connected to the outer wall of the outlet 3, and a drive motor 5 installed on the outer wall of the fixing frame 4; this structure can drive a rotating shaft 16 to rotate automatically through the drive motor 5, realizing the automatic winding of the pull rope 6; multiple fixing frames 4 are distributed in a circular and equally spaced manner around the outer wall of the outlet 3, and the rotating shaft 16 is rotatably connected inside the fixing frame 4; a dustproof cloth cover 7 is fitted and fixedly installed at the lower end of the outlet 3, and a connector 8 is fixedly connected to the lower outer wall of the dustproof cloth cover 7; this... The structure uses a dustproof cloth cover 7 to intercept dust during the loading of crops, thereby reducing dust dispersion. A pull rope 6 is wound around the outer wall of the rotating shaft 16, with one end connected to one end of the connector 8. Rotation of the shaft 16 allows the pull rope 6 to be wound or unwound. When the pull rope 6 is wound, the dustproof cloth cover 7 can be retracted; when it is unwound, it is unfolded. The height of the dustproof cloth cover 7 can be adjusted by winding the pull rope 6, allowing it to be adjusted to match the height of the crop pile. A filter cylinder 11 is integrally connected to the inner wall of the discharge port 3, and a conveying pipe 2 is connected to one side of the discharge port 3. The conveying pipe 2 is connected to a drive box 9 on one side. Openings are provided on both sides of the drive box 9. A first filter screen 12 is installed inside one opening of the drive box 9, and the other opening of the drive box 9 is connected to the conveying pipe 2. The first filter screen 12 is located on one side of the exhaust fan 13. This structure, through the first filter screen 12 and the second filter screen 14, can filter dust in the air, preventing dust from affecting the operation of the exhaust fan 13. The top of the drive box 9 is fixedly connected to the harvester discharge pipe 1. The exhaust fan 13 is installed inside the drive box 9, and a collection box 10 is inserted inside the drive box 9. The filter screen cylinder 11 can separate dust and impurities from the crops during the crop feeding process. Collection; the collection box 10 is located on the other side of the exhaust fan 13. The collection box 10 has openings on both sides. A second filter screen 14 is installed on the inner wall of one opening of the collection box 10. A baffle 15 is movably connected to the inner side of the other opening of the collection box 10. The other opening of the collection box 10 corresponds to the position of the conveying pipe 2. The baffle 15 is made of plastic. When the exhaust fan 13 is turned on, the baffle 15 can open under the action of suction to realize the automatic adsorption and collection of dust. When the exhaust fan 13 is turned off, the baffle 15 can be reset to block the other opening of the collection box 10 to prevent dust from entering the inside of the conveying pipe 2. The left side of the harvester discharge pipe 1 of this device is connected to the harvester body.

[0023] Working principle: When using the dustproof structure for low-profile crop harvesters, the crops are first conveyed through the harvester's discharge pipe 1 and discharged from the outlet pipe 3. When the crops enter the outlet pipe 3, they are located inside the filter screen cylinder 11. Since the exhaust fan 13 is working, the baffle 15 opens under the action of suction. The dust and impurities in the crops inside the outlet pipe 3 pass through the filter screen cylinder 11 and enter the conveying pipe 2, and are then collected in the collection box 10. The crops then enter the dustproof cloth cover 7 through the lower end of the outlet pipe 3 and are then loaded onto the vehicle. As the amount of crops loaded onto the vehicle increases, the drive motor 5 drives the rotating shaft 16 to rotate. During the rotation of the rotating shaft 16, the pull rope 6 winds around, and at this time, the pull rope 6 drives the dustproof cloth cover 7 to retract, so that the dustproof cloth cover 7 is at a suitable height.
