Description

Technical Field

[0001] This utility model relates to the field of grain unloading devices for grain warehouses, and in particular to a grain unloading device for a harvester grain warehouse. Background Technology

[0002] A harvester is an integrated machine for harvesting crops. It completes harvesting and threshing in one go, collects the grains in a storage bin, and then transports the grain to a transport vehicle via a conveyor belt. Manual harvesting can also be used, where the stalks of crops such as rice and wheat are laid out in the field and then picked up and threshed by grain harvesting machinery. Types of harvesters include combine harvesters, small harvesters, portable harvesters, and walk-behind harvesters. Currently, combine harvesters and small harvesters are the main types. For example, large combine harvesters are mainly used in the Northeast Plain, while in the South, due to the terrain, large harvesters are not convenient to operate, so small harvesters are mainly used.

[0003] Currently, the unloading methods of small harvesters are relatively simple, mainly due to the need to control production costs. They only have basic unloading functions, and their angle adjustment and unloading methods are relatively limited, thus restricting their practicality. For example, during unloading, the harvester will transport the grain from the grain bin to the adjacent vehicle. In this process, the grain unloaded from the unloading port will accumulate into a pile, which needs to be manually cleared and leveled, or the harvester needs to be moved back and forth to unload the grain. In this process, manually clearing and leveling the grain will cause dust to enter the respiratory tract, which will affect health. Moving the harvester back and forth is fuel-consuming and labor-intensive, and the unloading port has a single function and unloading method, which limits its applicability.

[0004] Therefore, it is necessary to propose a grain unloading device for harvesters to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a grain unloading device for a harvester, so as to solve the problems mentioned in the background art, such as the problem that manually digging and leveling the grain pile will cause dust to enter the respiratory tract and affect health, and that moving the harvester back and forth is fuel-consuming and labor-intensive, and that the unloading port has a single function and a single unloading method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grain unloading device for a harvester grain bin, comprising a main body of equipment, a grain storage cavity inside the main body of equipment, and an inclined plate installed inside the main body of equipment;

[0025] This utility model provides, for example Figures 1-4 The grain unloading device for a harvester shown includes a main body 1, a grain storage chamber 2 inside the main body 1, and an inclined plate 3 installed inside the main body 1. The functions of the inclined plate 3 are to help the grain fall and to limit the falling speed to avoid the grain being discharged too quickly and causing the grain to get stuck.

[0026] A protective plate 10 is installed on one side of the main body 1 of the equipment. A fixing plate 8 is installed in front of the protective plate 10. The fixing plate 8 is a U-shaped iron sheet, which facilitates the vertical angle adjustment of the unloading bucket 6. The unloading bucket 6 is installed on the fixing plate 8 and the unloading bucket 6 passes through the fixing plate 8.

[0027] The upper end of the unloading bucket 6 is equipped with a conical unloading port 5, the conical unloading port 5 is threaded 15, the top cover 4 is screwed on the conical unloading port 5, the middle end of the conical unloading port 5 is equipped with a clamp 7, the clamp 7 is a fastener, the purpose of which is to ensure overall stability, and the lower end of the conical unloading port 5 is equipped with a connecting shaft 12.

[0028] The unloading bucket 6 is equipped with a vertical screw 32, and a first bevel gear 29 is installed at the lower end of the vertical screw 32.

[0029] The main unloading port 19 is installed on the front surface of the unloading hopper 6 near the top. The upper surface of the main unloading port 19 has a groove 17. The front surface of the main unloading port 19 is equipped with a retaining strip 18. A baffle 20 is slidably installed on the retaining strip 18.

[0030] A movable block 22 is installed in the groove 17. A vertical spring 28 is installed on the rear surface of the movable block 22. The rear end of the vertical spring 28 is fixedly connected to the outer surface of the unloading bucket 6. A second inclined spring 23 is installed on one side of the movable block 22. A second fixing block 24 is fixedly installed on the other end of the second inclined spring 23. A second unloading port 25 is installed on the lower surface of the second fixing block 24. A first inclined spring 27 is installed on the other side of the movable block 22. A first fixing block 26 is fixedly installed on the other end of the first inclined spring 27. A first unloading port 21 is installed on the lower surface of the first fixing block 26.

[0031] Furthermore, a protective disc 16 is installed on the connecting shaft 12. There are two protective discs 16. The purpose of the protective discs 16 is to prevent foreign objects from entering the pinion 31 and causing damage and safety accidents. The pinion 31 is installed between the protective discs 16.

[0032] Furthermore, a second bevel gear 30 is installed at the other end of the connecting shaft 12.

[0033] Furthermore, there are two grain-gathering plates 13 installed inside the main body 1 of the equipment, and a horizontal screw 14 is installed between the grain-gathering plates 13.

[0034] Furthermore, a large gear 9 is installed at the other end of the horizontal screw 14, and the large gear 9 is connected to the small gear 31 via a belt.

[0035] Furthermore, a linkage turntable 11 is installed on one side of the protective plate 10. The linkage turntable 11 is connected to the horizontal screw 14 through a rotating shaft. The linkage turntable 11 serves as a warning during use. After the horizontal screw 14 stops running, it will continue to rotate without power for a period of time due to inertia. During this process, the linkage rotation of the linkage turntable 11 serves as a reminder to the user that the horizontal screw 14 is still running.

[0036] It should be noted that this utility model is a grain unloading device for a harvester's grain bin. During use, grain enters the grain-collecting plate 13 through the grain storage chamber 2. During this process, the inclined plate 3 assists in the grain's descent, limiting the descent speed to prevent excessively fast discharge and potential grain jamming. Then, the horizontal screw 14 begins to rotate. During this rotation, the large gear 9 drives the small gear 31 to rotate, which in turn drives the connecting shaft 12 to rotate. The second bevel gear 30 on the connecting shaft 12 then drives the first bevel gear 29 to rotate. Wheel 29 drives vertical screw 32 to rotate, thus forming a linkage rotation. Grain can be transported through unloading bucket 6 to main unloading port 19. At this time, under the influence of gravity, movable block 22 will drive unloading port 21 and unloading port 25 to fall, forming an angle to divert the grain falling from main unloading port 19. This solves the problem that grain piles up and forms a grain heap when there is only one unloading port, which requires manual clearing and flattening. It also solves the problem that dust inhalation by users will cause respiratory harm. The rapid grain unloading is thus completed.

[0037] When using the equipment, if bagging and unloading of grain is required, simply move the baffle 20 to close the main unloading port 19 and proceed with bagging and unloading. During bagging and unloading, the top cover 4 needs to be unscrewed, the bag placed below the conical unloading port 5, and the grain discharge speed can be controlled manually by rotating the linkage turntable 11. This is especially suitable for small farmland, where the area is small, allowing for on-site harvesting and loading, avoiding the need to hire additional grain loading vehicles, saving costs, and enhancing applicability. Considering that after the horizontal screw 14 stops running during use, it will continue to rotate without power for a period of time due to inertia, and approaching the horizontal screw 14 at this time could cause an accident, the linkage turntable 11 also serves as a warning during use. The linkage rotation of the linkage turntable 11 reminds the user that the horizontal screw 14 is still running and that they should not approach it, thus improving the safety of the device.
