Technical Field
[0001] This invention belongs to the field of corn harvesting technology, and particularly relates to a corn harvester separating device with adjustable gaps. Background Technology
[0002] The function of the dividing device is to divert corn stalks into the ear-picking gaps. Existing horizontal corn harvesters have dividing devices fixed in front of the harvesting platform, with a fixed gap that cannot be adjusted in real time. Because corn row spacing varies across different regions and plots, the dividing gap may not match the corn row spacing during harvesting, leading to significant corn loss if forced to harvest. Therefore, there is an urgent need for a corn harvester dividing device with adjustable gaps to address this issue. Summary of the Invention

[0008] An intermediate divider is movably mounted on the frame. Multiple intermediate dividers are provided and are located between the fixed divider and the end divider. Several intermediate dividers are symmetrically arranged on both sides of the fixed divider.
[0009] A gap adjustment mechanism is drivenly connected to the two end dividers and the plurality of intermediate dividers, and is used to adjust the gap between the end dividers and the intermediate dividers, the gap between the two intermediate dividers, and the gap between the intermediate dividers and the fixed dividers.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] Reference Figures 1 to 4 This invention discloses a corn harvester splitting device with adjustable gaps, comprising:
[0033] The fixed divider 7 is fixedly connected to the frame at its rear end 6.
[0034] The end divider 2 is movably mounted on the frame, with the two end dividers 2 located on either side of the fixed divider 7.
[0035] Intermediate divider 1 is movably mounted on the frame. Multiple intermediate dividers 1 are provided. The intermediate dividers 1 are located between the fixed divider 7 and the end divider 2. Several intermediate dividers 1 are symmetrically arranged on both sides of the fixed divider 7.
[0036] The gap adjustment mechanism 4 is connected to two end dividers 2 and several intermediate dividers 1 for adjusting the gap between the end dividers 2 and the intermediate dividers 1, the gap between the two intermediate dividers 1, and the gap between the intermediate dividers 1 and the fixed divider 7.
[0037] In use, the device is installed on a frame, which is used to connect the device to the corn harvester. The frame is located at the front of the corn harvester in the direction of travel. Then, the device is used to divide and harvest the corn. When it is necessary to adjust the size of the dividing gap, the gap adjustment mechanism 4 drives the middle dividing device 1 and the end dividing device 2 to move closer to or further away from the fixed dividing device 7, thereby adjusting the dividing gap, enhancing adaptability during corn harvesting, reducing corn harvesting losses, and improving economic benefits.
[0038] The fixed divider 7 is fixed to the fixed divider end 6 by welding to the divider fixing plate, which is fixed to the frame.
[0039] Further optimization of the scheme: the gap adjustment mechanism 4 includes a translation drive structure 10, which is mounted on the frame and is correspondingly mounted to the fixed divider 7.
[0040] One end of the translation drive structure 10 is connected to a telescopic hydraulic cylinder assembly 9;
[0041] The other end of the translation drive structure 10 is connected to a drive plate 14, which is connected to the corresponding intermediate divider 1 or end divider 2 via an adjustment structure 8.
[0042] Further optimization of the scheme: the translation drive structure 10 includes a main drive rotating plate 12. One end of the main drive rotating plate 12 is rotatably mounted on the frame via a rotating shaft, and the other end of the main drive rotating plate 12 is hinged to the middle of the drive plate 14.
[0043] The main drive rotating plate 12 is connected to the telescopic hydraulic cylinder assembly 9 via a transmission connection.
[0044] The scheme is further optimized so that one end of the crank arm bracket 13 is fixedly connected to the middle of the main drive plate 12, and the other end of the crank arm bracket 13 is connected to the telescopic cylinder assembly 9 for transmission.
[0045] Further optimization of the scheme: the telescopic cylinder assembly 9 includes a telescopic part, the movable end of which is hinged to the other end of the crank arm bracket 13, and the fixed end of the telescopic part is hinged to a mounting bracket 902, which is fixed to the frame.
[0046] The design is further optimized so that the telescopic part includes a telescopic cylinder 901. One end of the telescopic cylinder 901 is hinged to the end of the crank arm bracket 13 away from the main drive rotating plate 12, and the other end of the telescopic cylinder 901 is hinged to the mounting bracket 902.
[0047] Further optimization of the scheme: the adjustment structure 8 includes a drive rotating plate 18, one end of which is hinged to the drive plate 14, and the other end of which is connected to a translation structure. The translation structure is connected to the rear end 3 of the end divider 2 or the rear end 5 of the middle divider 1.
[0048] Further optimization of the scheme: the translation structure includes two triangular rotating plates 20. The first corner of the triangular rotating plate 20 is hinged to a divider fixing plate 15 by a locking nut 19. The divider fixing plate 15 is fixedly connected to the end rear end 3 of the corresponding end divider 2 or the end rear end 5 of the intermediate divider 1.
[0049] The top end of a rotating shaft that is rotatably connected to the frame is fixed to the second corner of the triangular rotating plate 20. The bottom end of the rotating shaft fixed to the second corner of the triangular rotating plate 20 near the drive plate 14 is fixed to the end of the corresponding drive rotating plate 18 away from the drive plate 14.
[0050] A connecting rod 16 is hinged between the two triangular rotating plates 20, and the end of the connecting rod 16 is hinged to the triangular part of the corresponding triangular rotating plate 20.
[0051] In use, one end of the mounting bracket 902 is fixed to the frame, and the other end is hinged to the fixed end of the telescopic cylinder 901. The telescopic end of the telescopic cylinder 901 is hinged to the end of the crank arm bracket 13, and the other end of the crank arm bracket 13 is fixed to the middle of the main drive rotating plate 12. When the telescopic cylinder 901 moves telescopically, the crank arm bracket 13 drives one end of the main drive rotating plate 12 to rotate around its rotation axis with the frame. The end of the main drive rotating plate 12 away from the frame drives the drive plate 14 to move in translation. When the drive plate 14 moves, one end of each drive rotating plate 18 hinged to the drive plate 14 moves together with the translation of the drive plate 14. The other end of the drive rotating plate 18 is fixed to the bottom of the rotating shaft on the second corner of the corresponding triangular rotating plate 20, so that the drive rotating plate 18 can drive the rotating shaft to rotate on the frame. At the same time, the top end of the rotating shaft is fixed to the second corner of the triangular rotating plate 20, so that the three The triangular rotating plate 20 rotates around its second angle as the axis of rotation. The two triangular rotating plates 20 located in the same translation structure are connected together by a connecting rod 16. When one of the triangular rotating plates 20 rotates around its second angle as the axis of rotation, the other triangular rotating plate 20 also rotates around its second angle as the axis of rotation under the action of the connecting rod 16. At this time, the first angles of the two triangular rotating plates 20 will drive the divider fixing plate 15, which is hinged to them, to translate. The divider fixing plate 15 is used to fix to the corresponding intermediate divider 1 or end divider 2, so that the intermediate divider 1 and end divider 2 located on the same side of the fixed divider 7 can move simultaneously, changing the divider gap. Since the adjustment structures 8 located on both sides of the translation drive structure 10 are symmetrically arranged, the divider gap can be increased or decreased simultaneously to enhance adaptability during corn harvesting, reduce corn harvesting losses, and improve economic benefits.
