Description

Technical Field

[0001] This utility model relates to the field of harvester technology, specifically to a harvester header mounting mechanism. Background Technology

[0002] As an agricultural harvesting machine serving animal husbandry, the main function of the harvester's header attachment mechanism is to connect the main unit and the header through attachment, forming a complete harvester.

[0003] However, existing harvester header mounting mechanisms use bolts and nuts to fix the header to the chassis frame. Since harvesters are used in farmland, where the terrain is uneven, this leads to significant vibrations and loosening of the bolts and nuts. This results in poor stability of the connection between the header and the chassis frame, affecting header operation. Therefore, an innovative design based on the existing harvester header mounting mechanism is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a harvester header attachment mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a harvester header attachment mechanism, including a vehicle body attachment frame, the vehicle body attachment frame being provided with docking seats, docking blocks being installed between the docking seats, the docking blocks being interconnected with the header, bolts penetrating the interior of both the docking blocks and the docking seats, the bolts being threaded with nuts, and both the bolts and nuts having annular limiting grooves, an L-shaped plate being provided on the vehicle body attachment frame, a limiting rod penetrating the L-shaped plate, the limiting rod penetrating the interior of the annular limiting groove, a fixing ring being fixed to the limiting rod, and a spring nested within the limiting rod, the spring being located between the fixing ring and the L-shaped plate.

[0006] Preferably, the docking blocks are provided in two groups, with two docking blocks in each group, and the docking blocks in each group are symmetrically distributed about the central axis of the cutting table.

[0007] Preferably, a pull plate is provided at the end of the limiting rod away from the bolt, and the limiting rod and the pull plate are combined to form a "T" shaped structure.

[0008] Preferably, a locking rod is installed on the outer wall of the limiting rod, the top of the L-shaped plate is located between the spring and the locking rod, a locking plate is provided on the outer side of the L-shaped plate, and a locking groove is provided at the end of the locking plate.

[0009] Preferably, the height of the slot is greater than the diameter of the lever.

[0010] Preferably, the diameter of the retaining ring is larger than the diameter of the spring.

[0011] Preferably, the outer side of the limiting rod is in contact with the inner side of the annular limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: under the elastic force of the spring, the limiting rod can pass through the interior of the annular limiting groove. Thus, under the limitation of the two limiting rods and the two annular limiting grooves, the bolts and nuts will not move, ensuring that the bolts and nuts will not loosen during the harvester's operation in uneven farmland, and improving the stability of the fixing between the header and the vehicle body mounting frame. The limit rod is moved by pulling the pull plate, causing the end of the limit rod to separate from the annular limit groove. The limit rod drives the fixing ring to further compress the spring. At the same time, the limit rod drives the locking rod to move. When the moving distance of the locking rod is greater than the length of the locking plate, the pull plate is rotated 90 degrees. The pull plate drives the limit rod and the locking rod to rotate 90 degrees. The pulling force on the pull plate is gradually reduced. Under the action of the spring force, the end of the locking rod engages with the locking groove, so that the position of the limit rod is fixed after the movement, ensuring that the limit rod will not hinder the disassembly of the bolts and nuts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5This utility model provides a technical solution: a harvester header attachment mechanism, including a vehicle body attachment frame 1. A docking seat 4 is fixed to the top and bottom upper surfaces of the vehicle body attachment frame 1. A docking block 3 is engaged between the docking seats 4. The end of the docking block 3 is fixedly connected to one side of the header 2. Bolts 5 slide through the interior of both the docking block 3 and the docking seat 4. A nut 6 is threaded onto the end of the bolt 5. An annular limiting groove 7 is provided inside both the other end of the bolt 5 and the nut 6. An L-shaped plate 15 is fixed to the vehicle body attachment frame 1, and the L-shaped plate 15 slides through the limiting groove 7. Positioning rod 8, the end of which slides through the interior of the annular limiting groove 7. A fixing ring 9 is nested and fixed on the outer wall of the limiting rod 8. A spring 10 is nested on the outer side of the limiting rod 8. The spring 10 is located between the fixing ring 9 and the L-shaped plate 15. Under the limitation of the two limiting rods 8 and the two annular limiting grooves 7, the bolt 5 and nut 6 will not move, thus preventing loosening between the bolt 5 and nut 6. This allows the cutting table 2 and the vehicle body mounting bracket 1 to be stably fixed together, improving the stability of the installation between the cutting table 2 and the vehicle body mounting bracket 1, which is beneficial to the operation of the cutting table 2.

[0017] In this example, there are two sets of docking blocks 3, with two docking blocks 3 in each set. The docking blocks 3 in each set are symmetrically distributed about the central axis of the cutting table 2, which increases the number of fixing points between the cutting table 2 and the vehicle body mounting bracket 1 and improves the stability of the installation between the cutting table 2 and the vehicle body mounting bracket 1.

[0018] In this example, a pull plate 11 is fixed at the end of the limiting rod 8 away from the bolt 5. The limiting rod 8 and the pull plate 11 are combined to form a "T"-shaped structure, and the movement of the limiting rod 8 can be easily achieved by pulling the pull plate 11.

[0019] In this example, the outer wall of the limiting rod 8 is fixed with a locking rod 12. The top of the L-shaped plate 15 is located between the spring 10 and the locking rod 12. The outer side of the L-shaped plate 15 is fixed with a locking plate 13. The end of the locking plate 13 is provided with a locking groove 14. The locking rod 12 can be moved by pulling it with the limiting rod 8. By rotating the limiting rod 8 ninety degrees, the locking rod 12 can be rotated ninety degrees. Under the elastic force of the spring 10, the locking rod 12 can be engaged with the locking groove 14, so that the position of the limiting rod 8 after being separated from the annular limiting groove 7 can be fixed, which facilitates the disassembly and installation of the bolt 5 and the nut 6.

[0020] In this example, the height of the slot 14 is greater than the diameter of the lever 12, so that the end of the lever 12 can be locked inside the slot 14.

[0021] In this example, the diameter of the retaining ring 9 is larger than the diameter of the spring 10, which ensures that the retaining ring 9 can compress the spring 10 when it moves toward the L-shaped plate 15.

[0022] In this example, the outer side of the limiting rod 8 fits into the inner side of the annular limiting groove 7, so that the bolt 5 and nut 6 will not move after the limiting rod 8 is inside the annular limiting groove 7.

[0023] Working principle: When using the header attachment mechanism of this harvester, firstly Figure 2 The spring 10 is in a compressed state. Under the elastic force of the spring 10, the limiting rod 8 can pass through the interior of the annular limiting groove 7. Thus, under the limitation of the two limiting rods 8 and the two annular limiting grooves 7, the bolt 5 and nut 6 will not move. This ensures that the bolt 5 and nut 6 will not loosen during the harvester's operation in the bumpy farmland, and improves the stability of the fixing between the header 2 and the vehicle body bracket 1. When the cutting table 2 needs to be disassembled, the limit rod 8 is moved by pulling the pull plate 11, so that the end of the limit rod 8 separates from the annular limit groove 7. The limit rod 8 drives the fixing ring 9 to further compress the spring 10. At the same time, the limit rod 8 drives the locking rod 12 to move. When the moving distance of the locking rod 12 is greater than the length of the locking plate 13, the pull plate 11 is rotated 90 degrees. The pull plate 11 drives the limit rod 8 and the locking rod 12 to rotate 90 degrees. Gradually reduce the pulling force on the pull plate 11. Under the elastic force of the spring 10, the end of the locking rod 12 engages with the locking groove 14, so that the position of the limit rod 8 is fixed after it moves. This ensures that the limit rod 8 will not hinder the disassembly of the bolt 5 and nut 6. Finally, the bolt 5 and nut 6 are disassembled with a wrench, and the vehicle body mounting bracket 1 and the cutting table 2 can be disassembled.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
