Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disc harrows, in particular to a hilly land contouring disc harrow mechanism. Background Art
[0002] The disc harrow is a traditional tillage tool used in agriculture. Once an essential farm tool, it's also a Chinese martial arts instrument, evolving from a farm tool. The disc harrow works based on the principle of harrowing, using a set of concave discs as its working components. The blades are perpendicular to the ground and have an adjustable angle relative to the machine's forward motion. During operation, the harrows roll forward under the pull of the tractor and the reaction force of the soil. The blades cut into the soil, severing grass roots and crop residue, and causing the soil to rise to a certain height along the concave surface before flipping and falling.
[0003] After searching, the existing Chinese patent announcement number is: CN220383497U, which provides a disc harrow that is easy to cultivate. The patent uses an adjustment mechanism to adjust the relative position of two sets of adjustment rods and the support frame, so that the distance between the two support seats can be adjusted, and then the distance between the two sets of disc harrow bodies can be adjusted, so that the occupied space of the device can be adjusted according to the size of different farmlands. When the farmland is large, the distance between the two sets of disc harrow bodies is increased. When the farmland is small, the distance between the two sets of disc harrow bodies is reduced, so that the disc harrow can be flexibly used in small areas of farmland. The function solves the problem that it is difficult to adjust the distance between the two sets of disc harrows in the traction-type disc harrow in the comparative patent and most disc harrows in the prior art. Therefore, if the distance between the two sets of disc harrows of some discs is too large, it will occupy a large space. When used in the farmland by a tractor, it may be difficult to turn flexibly in a small farmland, which may affect the flexibility of the disc harrow. The flexibility of the use of the device is improved.
[0004] Although the above patent can adjust the relative positions of the two sets of adjustment rods and the support frame, thereby adjusting the distance between the two support seats, and then adjusting the distance between the two sets of disc harrow bodies, the above-mentioned disc harrow that is easy to cultivate still has the following problems: when the disc harrow is used on mountain rocky ground, the disc harrow cannot swing left and right and up and down, which makes it easy for the disc to collide with the stone, resulting in damage to the disc.
