[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 A harvester with a collision avoidance device includes a main body 1, a header 2, wheels 3, and an operator's cab 4. The header 2 is fixedly installed on one end of the main body 1, the wheels 3 are installed at the bottom of the main body 1, and the operator's cab 4 is installed on the main body 1. It also includes a support component 5, an auxiliary component 6, and a buffer component 7. The support component 5 is fixedly installed on the header 2, the auxiliary component 6 is installed on the support component 5, and the buffer component 7 is installed on the support component 5.

[0021] The support bar 501 in the support assembly 5 is fixedly installed on the cutting table 2. The support bar 501 is arc-shaped and installed at the outer end of the cutting table 2. The two ends of the support bar 501 are provided with mounting ends 502.

[0022] When in use, as the harvester moves into the field to carry out operations, the support bar 501, with its unique arc design, forms a protective barrier on the outside of the header 2. When working near the edge of the field, if there are trees or small obstacles, the support bar 501 will be the first to come into contact with them. When the support bar 501 collides with any low shrubs, its own structure disperses the impact force, and the mounting end 502 firmly fixes the support bar 501 to the header 2 to prevent it from falling off. This effectively avoids obstacles directly impacting the header 2, providing reliable protection for subsequent harvesting operations.

[0023] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The snap-fit ​​sleeve 601 in the auxiliary component 6 is fixedly installed on the installation end 502, and the snap-fit ​​sleeve 601 is fitted with a fixing rod 602.

[0024] The fixing rod 602 in the auxiliary component 6 is rotatably fixed on the mounting rod 603, and a drive motor 604 is fixedly installed on the other end of the fixing rod 602.

[0025] When the harvester faces a complex working environment, such as a narrow passage or when it needs to bypass large obstacles, the drive motor 604 starts working. The drive motor 604 precisely controls the speed, driving the fixed rod 602 to rotate smoothly on the mounting rod 603. Since the fixed rod 602 is tightly engaged with the snap-fit ​​sleeve 601, the snap-fit ​​sleeve 601 will rotate accordingly, thereby driving the support bar 501 to adjust its angle. By starting the drive motor 604, the support bar 501 can rotate flexibly, allowing the harvester to cleverly avoid obstacles. This not only reduces the risk of collision, but also ensures that the header 2 always maintains a suitable working angle, ensuring smooth and continuous harvesting action, and greatly enhancing the equipment's adaptability to working in complex environments.

[0026] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The buffer strip 701 in the buffer assembly 7 is fixedly mounted on the support strip 501. The buffer strip 701 is attached and fixed to the support strip 501. Buffer protrusions 702 are evenly arranged inside the buffer strip 701.

[0027] The buffer protrusion 702 in the buffer assembly 7 is provided with folded grooves 703 evenly distributed, and a spring 704 is fixedly installed inside the buffer protrusion 702.

[0028] In use, if the harvester accidentally collides with an obstacle, the buffer strip 701 immediately plays a buffering role. At the moment of impact, the impact force acts on the buffer protrusion 702, causing the folding groove 703 on it to fold under force, and the internal spring 704 is compressed. For example, when the harvester hits an obstacle, the elastic potential energy of the spring 704 and the deformation of the folding groove 703 together absorb a large amount of impact force, greatly reducing the force transmitted to the support strip 501 and the header 2. During this process, the buffer protrusion 702 will adaptively adjust according to the magnitude of the impact force, continuously buffering until the impact force is completely dissipated, effectively reducing the possibility of mechanical structure deformation, ensuring the safe and stable operation of the harvester, reducing downtime maintenance time caused by collisions, and improving overall operating efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
