Description

Technical Field

[0001] This utility model relates to the field of agricultural harvester technology, specifically a multi-functional agricultural harvester structure. Background Technology

[0002] Agricultural harvesters are key equipment for achieving agricultural modernization and improving agricultural production efficiency, playing a vital role in agricultural production. Large-scale combine harvesters are characterized by high operating efficiency, high functional integration, and wide adaptability. They have a large feeding capacity, reaching over 10 kilograms per second, and can harvest dozens or even hundreds of acres of crops per day, greatly shortening harvest time.

[0003] Existing harvesters generate dust during the cutting, threshing, and straw crushing processes. For example, combine harvesters thresh wheat directly after harvesting, and some even crush the wheat straw and return it to the field. During these processes, crop straw and husks are broken into fine particles, creating dust. Some of this dust is also carried into the hopper along with the wheat. When the wheat is subsequently removed from the hopper for collection, a large amount of dust may be stirred up, which can easily be inhaled by workers, posing a health hazard. Utility Model Content

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-5This utility model discloses a multifunctional agricultural harvester structure, including a harvester body 1, which includes a discharge port 11 and a hopper 12. The harvester body 1 is a harvester with a hopper 12, used for harvesting crops such as wheat. The discharge port 11 is the discharge point. A dust removal component is provided on the upper inner side of the hopper 12. The dust removal component includes a dust removal box 13, with a discharge port 15 at the bottom of the dust removal box 13 and a connection port 14 on one side of the upper part of the dust removal box 13. The discharge port 11 is connected to the connection port 14, and the connection port 14 and the discharge port 15 are connected to the inside of the dust removal box 13. The crops harvested by the harvester are transported to the connection port 14 through the discharge port 11 and then enter the dust removal box 13. After dust removal, they enter the hopper 12 through the discharge port 15 for temporary storage.

[0027] The dust collector 13 is equipped with a bidirectional spiral blade 2 inside. A first motor 21 is installed on one side of the bidirectional spiral blade 2. The drive shaft of the first motor 21 is connected to the bidirectional spiral blade 2. That is, the first motor 21 drives the bidirectional spiral blade 2 to rotate, thereby causing the crops inside the dust collector 13 to move to both sides and causing the dust in the crops to be stirred up.

[0028] An arc-shaped baffle 22 is installed at the top of the outlet 15. Arc-shaped rails 33 are installed on both sides of the dust collection box 13. Guide posts 23 are installed on both sides of the arc-shaped baffle 22. The guide posts 23 are slidably connected to the arc-shaped rails 33. Rotating rings 24 are rotatably installed on both sides of the guide posts 23. The rotating rings 24 are locked on the outside of the dust collection box 13 and rotate. A gear 3 is rotatably installed on the outside of one side of the arc-shaped rail 33. An electric telescopic rod 31 is installed on one side above the gear 3. A rack 32 is installed at the bottom of the electric telescopic rod 31. The rack 32 meshes with the gear 3. An internal tooth 25 is installed on the inside of one side of the rotating ring 24. The gear 3 meshes with the internal tooth 25. That is, the electric telescopic rod 31 drives the rack 32 to extend and retract. Through the gear 3, the internal tooth 25 drives the rotating ring 24 to rotate back and forth. This causes the arc-shaped baffle 22 inside to continuously open and close the outlet 15, slowing down the speed of falling crops and ensuring dust collection.

[0029] A baffle net 34 is installed on the top of the dust collection box 13. Above the baffle net 34 is a mounting groove 4, inside which a vacuum fan 45 is installed. The suction point of the vacuum fan 45 faces the baffle net 34, meaning that by activating the vacuum fan 45, the dust raised is absorbed. A dust collection bag is installed at the dust outlet of the vacuum fan 45 to collect the absorbed dust for subsequent processing. A sliding seat 41 is installed on the outside of the vacuum fan 45. A second motor 43 is installed on one side of the top of the mounting groove 4. A threaded rod 42 is provided on the drive shaft 43, and a threaded tube 44 is provided on one side of the top of the sliding seat 41. The threaded rod 42 and the threaded tube 44 are threadedly connected. Rollers 5 are rotatably provided on both sides of the outer side of the sliding seat 41. The rollers 5 are slidably connected to the mounting groove 4. That is, the mounting groove 4 limits the rollers 5, so that the vacuum cleaner 45 slides smoothly. That is, the second motor 43 drives the threaded rod 42 to rotate, so that the vacuum cleaner 45 moves back and forth in the mounting groove 4, thus ensuring that vacuuming is performed on different positions.

[0030] The working principle of this utility model is as follows: the crops harvested by the harvester are conveyed to the connection port 14 through the discharge port 11, and then enter the dust collection box 13. The first motor 21 drives the bidirectional spiral blades 2 to rotate, thereby causing the crops inside the dust collection box 13 to move to both sides and causing the dust in the crops to be raised. By starting the dust suction fan 45, the raised dust is absorbed. The second motor 43 drives the threaded rod 42 to rotate, thereby causing the dust suction fan 45 to move back and forth in the mounting groove 4, thus ensuring that dust is suctioned at different positions. After dust removal, the crops enter the hopper 12 through the discharge port 15 for temporary storage. The electric telescopic rod 31 drives the rack 32 to extend and retract. Through the gear 3 transmission, the internal gear 25 drives the rotating ring 24 to rotate back and forth, thereby causing the internal arc baffle 22 to continuously open and close the discharge port 15, slowing down the speed of the crops falling and ensuring dust suction, that is, minimizing the dust in the hopper 12.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
