Description

Technical Field

[0001] This utility model relates to the technical field of crop divider equipment, specifically to a crop harvesting divider. Background Technology

[0002] As a crucial component of harvesters, the crop divider separates crops during the harvesting process, guiding them smoothly into the header and preventing stalk entanglement and blockage, thereby improving harvesting efficiency and quality. However, existing crop dividers generally suffer from fixed structures and inconvenient adjustments. The angle and position of the dividing plate in most dividers cannot be flexibly adjusted according to the height of different crops and ground undulations, leading to incomplete division, missed harvesting, or damage caused by excessive friction between the dividing plate and the crop during harvesting. Therefore, a crop divider capable of multi-angle and multi-dimensional adjustment, and convenient installation and maintenance, has been designed to meet the diverse harvesting needs of modern agriculture. Utility Model Content

Through the coordinated action of a rotating component, a swinging component, and a supporting component, the dividing plate can achieve multi-dimensional adjustment of pitch angle, front-to-back distance, and height position. The rotating component allows the dividing plate to adjust the pitch angle according to the crop height and ground undulation. The swinging component can change the front-to-back angle of the dividing plate relative to the cutter head. The supporting component can adjust the height position of the dividing plate according to the crop height.

[0004] A crop harvester includes a dividing plate, which is triangular in shape. One end of a connecting plate is fixedly attached to the lower rear end of the dividing plate.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] A crop harvester includes a dividing plate 1, which is triangular in shape. One end of a connecting plate 3 is fixedly connected to the lower rear end of the dividing plate 1. The other end of the connecting plate 3 is connected to a support plate 7 via a rotating assembly. The support plate 7 is connected to an extension plate 12 via a swing assembly. A connecting block 6 is fixedly provided on one side of the extension plate 12. The connecting block 6 is connected to the support assembly.

[0016] Utilizing the guiding properties of a triangle, crops are separated to both sides during harvesting, reducing straw entanglement and guiding crops into the cutting platform. The position of the dividing plate 1 is adjustable through mechanical connection to adapt to different crop densities, row spacings, or harvester travel speeds.

[0017] As a further limitation of this technical solution, the rotating assembly includes a connecting shaft 16, and the other end of the connecting plate 3 is fixedly provided with the connecting shaft 16. The two ends of the connecting shaft 16 are respectively rotatably connected to the connecting ring 13. The outer end of the connecting shaft 16 is fixedly connected to the second screw, and the second screw is screwed with the second nut 14. The connecting ring 13 is fixed to one end of the support plate 7.

[0018] In this embodiment, the relative rotation between the connecting plate 3 and the support plate 7 is achieved through the shaft hole cooperation, forming a fulcrum for adjusting the pitch angle. After rotating the connecting shaft 16 to adjust the pitch angle of the support plate 7, it is locked and fixed by the nut to prevent shaking during operation. The support plate 7 is allowed to rotate around the connecting shaft 16 to adjust the up and down tilt angle of the dividing plate 1 to adapt to crops of different heights or ground undulations. The screw and nut structure provides mechanical locking to ensure angle stability during operation.

[0019] As a further limitation of this technical solution, the swing assembly includes the protruding plate 12, with a first screw fixedly connected to the upper side of one end of the protruding plate 12. The first screw passes through the other end of the support plate 7 and is screwed to a first nut 10.

[0020] In this embodiment, by loosening the first nut 10, the support plate 7 can be pulled to rotate, causing it to rotate around the first screw, thereby changing the position of the extension plate 12 relative to the support plate 7, and thus adjusting the angle of the dividing plate 1 relative to the installed cutting table. The first nut 10 can be tightened to fix the support plate 7 and the extension plate 12.

[0021] As a further limitation of this technical solution, the support assembly includes a fixed plate 4, a plurality of evenly arranged connecting holes 5 formed on the fixed plate 4, a connecting block 6, and a mounting plate 8. The connecting block 6 has a circular hole that can coaxially correspond to a connecting hole 5. A locking bolt can pass through the circular hole and the corresponding connecting hole 5 and then be screwed with a locking nut to lock the connecting block 6 and the fixed plate 4. The mounting plate 8 is fixedly connected to the lower side of the fixed plate 4, and mounting holes 9 are formed at the four corners of the mounting plate 8.

[0022] In this embodiment, multiple connecting holes 5 on the fixing plate 4 provide different lateral installation positions. The connecting block 6 is connected to different holes by bolts to realize the stepped adjustment of the height position of the divider. The divider is installed on the harvester header through the mounting holes 9. The four corners are fixed to ensure structural stability. The position of the connecting hole 5 is selected according to the crop height to avoid missing dividers.

[0023] As a further limitation of this technical solution, the support plate 7 and the fixing plate 4 are arranged vertically.

[0024] As a further limitation of this technical solution, a handle 2 is fixedly provided on the outer side of the dividing plate 1. The handle 2 provides a gripping point, making it convenient for operators to manually move the dividing plate 1 during installation, debugging or maintenance.

[0025] As a further limitation of this technical solution, the support components are symmetrically arranged and installed on both sides of the header of the harvester via the mounting plate 8. Each support component is connected to the dividing plate 1 via the swing component and the rotating component.

[0026] The working process of this utility model is as follows: Secure the mounting plate 8 of the support assembly to both sides of the harvester's header using bolts through the four corner mounting holes 9, ensuring symmetrical installation. Based on the crop height, select the appropriate connecting hole 5 on the fixing plate 4, aligning the round hole of the connecting block 6 coaxially with the corresponding connecting hole 5. Use a locking bolt to pass through the round hole and connecting hole 5, then screw on the locking nut to fix the connecting block 6 to the fixing plate 4, completing the initial adjustment of the divider's lateral position. Loosen the second nut 14 at the outer end of the connecting shaft 16 in the rotating assembly, and rotate the connecting shaft 16, causing the support plate 7 to rotate around the connecting shaft 16. Adjust the pitch angle of the divider plate 1 to adapt to different crop heights or ground undulations. After adjustment, tighten the second nut 14 to lock the pitch angle of the divider plate 1. Loosen the first nut 10 in the swing assembly, pulling the support plate 7 to rotate around the first screw, changing the position of the extension plate 12 relative to the support plate 7, thereby adjusting the front-to-back angle of the divider plate 1 relative to the header. After adjusting to the appropriate position, tighten the first nut 10 to fix the support plate 7 and the extension plate 12. After the operation is completed, if maintenance or disassembly of the divider is required, the operator can easily move the divider plate 1 through the handle 2 on the outside of the divider plate 1, loosen the fixing bolts or nuts of each component, and then remove the divider from the harvester header for cleaning, inspection and other maintenance operations.

[0027] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
