Description

Technical Field

[0001] The utility model relates to the technical field of grass discharge covers, in particular to a grass discharge cover for a harvester. Background Art

[0002] A harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, collects the grains into a storage bin, and then transports the grains to a transport vehicle via a conveyor belt. The harvester weed discharge hood is a key component of the harvester. Its main function is to guide and discharge weeds, straw and other residues separated from crops.

[0003] After searching, the patent number is CN205865107U, which discloses a harvester grass discharge cover, in which a wear-resistant and anti-corrosion layer is provided on the support plate, the wear-resistant and anti-corrosion layer is fitted with the support plate, and the wear-resistant and anti-corrosion layer is cast by epoxy resin or polyurethane as an integrated molding structure. The epoxy resin or polyurethane has excellent corrosion resistance and wear resistance, which effectively solves the problem that the existing harvester grass discharge cover support plate has poor wear resistance and corrosion resistance and poses a safety hazard. However, the device is an integrated structure and can only be installed on a harvester of a specific width and cannot be installed with harvesters of other widths. In addition, when the existing harvester grass discharge cover is damaged, the discharge plate cannot be replaced alone, which is inconvenient. For this reason, we propose a harvester grass discharge cover. Utility Model Content

[0010] Preferably, the first adjustment plate and the second adjustment plate are both slidably connected to the second blocking plate, and the first adjustment plate and the second adjustment plate are both fixedly connected to the first blocking plate.

[0011] Preferably, a sliding column is provided through the front side of the left side of the connecting plate, and the sliding column passes through the movable plate.

[0012] By adopting the above technical scheme, the fixing bolts are loosened to disengage the fixing bolts from the fixing plates, and then the fixing plates on both sides are pulled so that the fixing plates move to both sides through the cooperation of the L plate and the slider, and stop when the inner side of the fixing plate is consistent with the width of the harvester installation part, and then the fixing plates on both sides are fixed to the installation part by the fixing bolts, and the installation plate is located directly below the discharge part of the harvester, and then the installation plate and the discharge plate are fixed by the cooperation of the threaded column and the nut, and when the discharge plate is damaged or severely worn, the discharge plate can be directly disassembled and replaced, which improves the replacement speed of the harvester grass discharge cover, so that the harvester grass discharge cover can adjust the length of the fixing plate to adapt to harvesters of different widths, thereby improving the overall adaptability;

[0013] By adopting the above technical scheme, by starting the motor, the motor drives the first blocking plate to move inward in the connecting plate under the cooperation of the bidirectional screw and the movable plate. At this time, when the first blocking plate moves, it will drive the first adjusting plate and the second adjusting plate to approach each other respectively. When the first adjusting plate and the second adjusting plate are close to each other, the discharge port of the harvester grass discharge cover will also be reduced accordingly, and then it will be adjusted to the required position according to the actual situation and stop. At this time, through the cooperation of the first blocking plate and the second blocking plate, the two sides and the front and back sides of the first adjusting plate and the second adjusting plate can be closed to prevent grass from flying out, and the first adjusting plate and the second adjusting plate will slide on the second blocking plate when moving, thereby improving the stability of the first adjusting plate and the second adjusting plate. Then, through the cooperation of the sliding column, the movement of the movable plate is made more horizontal, so that the harvester grass discharge cover can adjust the discharge port of the discharge plate according to the actual situation to adapt to different working conditions, improve the flexibility and adaptability of the operation, and optimize the grass discharge effect and reduce crop losses.
