[0002] A harvester is a kind of agricultural machinery, mainly used for harvesting cereal crops such as wheat, corn and rice, etc. It can complete operations such as cutting, threshing, separating and cleaning in the field, and is a harvesting machine that directly obtains grains from the field, greatly improving the agricultural production efficiency, thus saving manpower and material resources and greatly reducing the labor burden of farmers.
[0003] When the harvester is operating, it cuts the roots of the grains through the cutter, and then conveys them into the crushing device through the transmission structure inside the harvester, and the grains are threshed by the crushing device. However, when the harvester reaches the end of the field, it needs to turn around. When the harvester turns around, the cutter is first lifted to prevent the cutter from touching obstacles. However, when the cutter is lifted, the angle between the cutter and the transmission belt inside the transmission mechanism changes, making the grains inside the cutter unable to enter the transmission belt. However, the reel inside the cutter is still rotating, which may cause the grains to be blocked between the transmission belt and the cutter, making the transmission belt unable to convey the grains. To solve this technical problem, the utility model proposes a harvester comprising a cutter transmission mechanism. Content of the Utility Model

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figures 1-5 As shown, a harvester including a harvester knife transmission mechanism includes a harvester body 1 and a harvester knife body 2. A transmission component 3 is installed above the harvester body 1. The upper surface of the transmission component 3 is connected to two support seats 4. The two support seats 4 are symmetrical. The grains transmitted by the transmission belt 9 are transported to the next processing link through the transmission component 3. The transmission component 3 is an existing conveying device and will not be introduced in detail here.
[0023] The inner wall of the support seat 4 is connected to a support sleeve 5, which provides support for the frame 6 and enables the frame 6 to have a rotation function. The frame 6 can adjust the angle by rotation to match the position of the harvesting knife body 2 moving up and down. The outer surface of the support sleeve 5 is rotatably connected to the frame 6, and the inner wall of the support sleeve 5 is rotatably connected to the rotating shaft 7. The transmission belt 9 is supported by the rotating shaft 7 and the support shaft 8, so that the transmission belt 9 has tension and maintains the stability of the transmission belt 9 during operation. The inner wall of the frame 6 is rotatably connected to multiple support shafts 8, and the outer sides of the support shaft 8 and the rotating shaft 7 are sleeved with a transmission belt 9. The outer surface of the transmission belt 9 is connected to multiple baffles 14, and the multiple baffles 14 are arranged at equal distances. The baffles 14 increase the contact force between the transmission belt 9 and the grain, which can better drive the grain to move. The support shaft 8 and the rotating shaft 7 are connected through the transmission belt 9.
[0024] One end of the support shaft 8 located outside the frame 6 is connected with a pulley 10. The rotating shaft 7 receives external power through the pulley 10. Through the power of the engine of the harvester body 1 itself, the pulley 10 is driven to rotate by a V-belt, the pulley 10 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the conveyor belt 9 to rotate, so as to convey grains to the transmission assembly 3. One end of the frame 6 located outside the harvester body 1 is connected with the harvesting knife body 2.
[0025] A hydraulic cylinder 11 is arranged below the frame 6. One side of the harvester body 1 is connected with a base one 12. The inner wall of the base one 12 is rotatably connected with the fixed end of the hydraulic cylinder 11. The lower surface of the frame 6 is connected with a base two 13. The base two 13 is rotatably connected with the output end of the hydraulic cylinder 11. The hydraulic cylinder 11 provides power for the up and down movement of the harvesting knife body 2. The base one 12 provides support force for the hydraulic cylinder 11. The frame 6 receives the driving force of the hydraulic cylinder 11 through the base two 13. The hydraulic cylinder 11 pushes the frame 6 to move, and while the frame 6 moves, it drives the harvesting knife body 2 to move up and down.
[0026] One end of the frame 6 located at the transmission assembly 3 is hinged with a support plate 15. The upper surface of the support plate 15 is connected with a docking plate 16, and the docking plate 16 is located inside the transmission assembly 3. Through the docking of the support plate 15 and the transmission assembly 3, the grains that slide backward can be blocked, reducing the spilling of grains outside during the harvesting process by the harvester. The gap between the support plate 15 and the transmission assembly 3 is sealed by the docking plate 16, improving the precision of the cooperation between the support plate 15 and the transmission assembly 3.
[0027] A support roller 17 is rotatably connected to the inner wall of the support plate 15. The support roller 17 is in contact with the outer surface of the transmission assembly 3. The support roller 17 has a rolling function. The support plate 15 contacts the transmission assembly 3 through the rolling of the support roller 17 to reduce friction.
[0028] The lower surface of the support plate 15 is connected with a base three 18. The inner wall of the base three 18 is rotatably connected with a pull rod 19. The lower surface of the frame 6 is connected with a base four 20. The outer surface of the pull rod 19 is slidably connected with the inner wall of the base four 20. The support plate 15 receives the pulling force through the base three 18, maintaining the contact force between the support plate 15 and the transmission assembly 3.
[0029] An adjusting block 21 is threadedly connected to the outer surface of the pull rod 19. A spring 22 is sleeved on the outside of the pull rod 19. One end of the spring 22 is in contact with one side of the adjusting block 21, and the other end of the spring 22 is in contact with one side of the base four 20. By rotating the adjusting block 21 to move its position, the elastic force of the spring 22 is changed. While the spring 22 changes its elastic force, the contact force between the support plate 15 and the transmission assembly 3 is changed, maintaining the contact force between the support plate 15 and the transmission assembly 3, preventing the support plate 15 from losing the pulling force and causing a gap between the support plate 15 and the transmission assembly 3.
[0030] It should be noted that in actual use of this device, first, the hydraulic cylinder 11 is started. The hydraulic cylinder 11 pushes the frame 6 to move upward. While the frame 6 moves, it drives the harvesting knife body 2 to move upward. After the frame 6 moves upward, the angle between the frame 6 and the transmission assembly 3 changes. While starting the hydraulic cylinder 11, the rotating shaft 7 drives the transmission belt 9 to rotate. The grains are conveyed to the transmission assembly 3 through the transmission belt 9. The conveyed grains continue to move into the transmission assembly 3 through the support plate 15. The support plate 15 smoothly conveys the grains into the conveying assembly.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
