Description

Technical Field

[0001] This application relates to the field of fenders for garden management machinery. Specifically, it relates to a fender structure with adjustable angles. Background Art

[0002] As a part of agricultural machinery, the fender blocks the splashed mud blocks during the operation of agricultural machinery, ensuring the safety of the staff and making the mud blocks fall on the ridges at a certain angle. Generally, the fender includes a fixed baffle (also called the inner fender) and two movable baffles (also called the outer fenders). The fixed baffle is fixed on the frame of the agricultural machinery equipment, and an angle adjustment mechanism is connected between the movable baffle and the fixed baffle. However, the shielding range of the existing movable fender and the fixed fender is limited, resulting in a poor shielding effect.

[0003] The structure of the product can refer to the angle-adjustable fender disclosed in the Chinese patent document with the publication number: CN218122322U, which includes a fixed baffle and two movable baffles. The movable baffles are located on both sides of the fixed baffle and can rotate relative to the fixed baffle. An angle adjustment member is provided between the fixed baffle and the movable baffle. The angle adjustment member includes a friction shaft and a clamping plate. If one of the friction shaft and the clamping plate is fixed on the movable baffle, the other is fixed on the fixed baffle. The clamping plate includes two opposite clamping pieces, and semi-accommodating cavities are formed on the opposite surfaces of the two clamping pieces. The two semi-accommodating cavities of the clamping plate clamp the friction shaft.

[0004] In the above structure, only the angle between the fixed baffle and the movable baffle can be adjusted to adjust the shielding range, and the position where the splashed mud blocks fall cannot be controlled. At the same time, the maximum shielding range is the state where the fixed baffle and the movable baffle are parallel, resulting in a large splashing range of the mud blocks, and the edge position of the movable baffle cannot be shielded, resulting in a poor shielding effect.

[0005] Therefore, a fender structure with adjustable angles and good shielding effect is needed. Summary of the Utility Model
