Abstract
Description
A corn harvesting and separating device for agricultural machinery Technical Field
[0001] This utility model relates to the technical field of crop processing devices, and in particular to a corn harvesting and separating device for agricultural machinery. Background Technology
[0002] Corn is an annual herbaceous plant belonging to the genus Zea in the family Poaceae. When harvesting corn, it is often necessary to separate the corn cob from the kernel.
[0003] Existing corn harvesting and separating devices, such as the utility model patent with patent application number CN202322797782.3 entitled "A Corn Harvesting and Separating Device for Agricultural Planting," disclose a corn harvesting and separating device for agricultural planting, including a box body. Corn is fed into the screening chamber through the feeding port. At the same time, a servo motor is started. The servo motor drives the first and second transmission shafts through the first and second gears, thereby driving the auger and threshing cone set on the surface of the first and second transmission shafts. The threshing cone performs the corn threshing operation, and the auger drives the corn in the screening chamber to move, thereby preventing material blockage. During threshing, a dust collector is started. The dust collector cleans the dust and some small shells generated during threshing through the dust pipe and dust port. The dust is transported to the dust collection box for collection through the pipeline, thereby reducing environmental pollution and the impact on the health of the threshing workers on site. The dust collection box achieves the effect of collection and easy cleaning.
[0004] When the above-mentioned device is in use, a lot of dust is generated during the separation of corn kernels. This dust easily accumulates on the filter plates in the dust collection box. If corn separation is carried out for a long time, the filter plates are prone to clogging, which is not conducive to subsequent use.
[0005] Therefore, a corn harvesting and separating device for agricultural machinery is provided to solve the problems mentioned above. Summary of the Invention

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Example:
[0029] Referring to Figures 1-5, a corn harvesting and separating device for agricultural machinery includes a separating box 1. An air pump 301 is fixedly connected to a door on the separating box 1. A dust suction port 302 for drawing dust and gas from inside the separating box 1 is connected to the air inlet of the air pump 301. A feed inlet 101 is fixedly connected to the separating box 1. The device also includes a filter box 4, fixedly connected to the separating box 1. Two sets of filter plates 5 are fixedly connected inside the filter box 4, spaced apart. The air outlet of the filter box 4 is connected to the air pump 301. The air inlet of the filter box 4 is connected to the air outlet of the dust suction port 302; a scraper 601 is slidably connected inside the filter box 4 and is used to scrape the filter plate 5; two sets of openings are provided on the side of the filter box 4 and are matched in size to the scraper 601; a partition 604 is slidably connected inside the opening and is used to block the opening; a limiting component is provided on the filter box 4 and is used to limit the partition 604, the limiting component including a baffle 701, a top block 702, and a top block 703. 703, baffle 701 is rotatably connected to filter box 4, top block 1 702 and top block 2 703 are both fixedly connected to filter box 4, and top block 1 702 and top block 2 703 are arranged opposite to each other. Two sets of limiting plates 401 are fixedly connected to filter box 4, and limiting grooves are provided on limiting plates 401. Limiting blocks matching the limiting grooves are provided on partition plate 604. A pull rod 602 is fixedly connected to scraper 601, one end of pull rod 602 passes through partition plate 604, and a... A motor 201 is fixedly connected to the connecting block 603 and the separation box 1. A rotating shaft 202 is rotatably connected inside the separation box 1. The rotating shaft 202 is fixedly connected to the output end of the motor 201. An auger 203 and a threshing cone 204 are fixedly connected to the rotating shaft 202. An inclined screening plate 102 is fixedly connected inside the separation box 1. A corn cob discharge outlet 103 is provided at the lower end of the screening plate 102 in the separation box 1. A corn kernel discharge outlet 104 is provided below the screening plate 102 in the separation box 1.
[0030] Corn enters the separation box 1 through the feed inlet 101. The motor 201 is started, which drives the rotating shaft 202 to rotate. The auger 203 and threshing cone 204 on the rotating shaft 202 start to work. The threshing cone 204 threshes the corn, while the auger 203 moves the corn within the separation box 1 to prevent material blockage. The threshed corn cobs and kernels are screened on the inclined screen plate 102. Due to their own weight and the inclination angle of the screen plate 102, the corn cobs are discharged from the corn cob discharge outlet 103. The corn kernels fall through the gaps in the screen plate 102 and are discharged from the corn kernel discharge outlet 104.
[0031] During the corn separation process, a large amount of dust and corn silk and other impurities are generated. At this time, the air pump 301 is started, and the dust gas in the separation box 1 is sucked into the filter box 4 through the dust suction port 302. When the dust gas passes through the two sets of filter plates 5 in the filter box 4, the dust and impurities are adsorbed by the filter plates 5. The filtered gas is then discharged through the air pump 301, thereby reducing environmental pollution and protecting the health of on-site operators.
[0032] As the usage time increases, a large amount of impurities will accumulate on the filter plate 5, affecting the filtration effect. At this time, the operator pulls the lever 602, which drives the scraper 601 to slide inside the filter box 4. The scraper 601 scrapes off the impurities accumulated on the filter plate 5. Before pulling the lever 602, the partition 604 is slid away from the opening to make room for the scraper 601 to slide. When the lever 602 is pulled, the connecting block 603 moves synchronously with the lever 602. During the sliding of the scraper 601, when the baffle 701 and the top block 702 are engaged... When the partition 604 can be moved out smoothly, the baffle 701 will restrict the position of the partition 604 when it is engaged with the top block 703. At the same time, the limiting groove on the limiting plate 401 and the limiting block on the partition 604 will cooperate to ensure the stability of the sliding of the partition 604. When it is blocked by the baffle 701, it will not fall out of the groove, thus improving stability. After cleaning, the scraper 601 is reset first, and then the partition 604 is slid back to the opening to block the opening. The baffle 701 is then moved to the position of the top block 703 to limit the partition 604 and prevent dust leakage.
[0033] This utility model, through the setting of filter box 4, can adsorb the dust generated by separating corn kernels and corn cobs in separation box 1. At the same time, the setting of scraper 601 can filter the impurities adsorbed on filter plate 5 in a timely manner, which facilitates the long-term use of filter plate 5.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
