Description

Technical Field

[0001] This utility model relates to the field of ditching technology for potato planting, and in particular to a ditching device for potato planting. Background Technology

[0002] Potatoes, a widely cultivated food crop, are grown extensively in both northern and southern my country. They thrive in deep, loose, well-drained, and aerated soils rich in organic matter. Therefore, organic fertilizers such as chicken manure and commercial organic fertilizers are frequently applied during potato cultivation. The acidification and decomposition of organic fertilizers generates heat, raising soil temperature, which is beneficial for soil microbial activity, root growth, and accelerating soil maturation. Organic fertilizers also improve soil structure, regulate pH, and enhance water and fertilizer retention capacity. Before fertilization, the land needs to be dredged. Using mechanical equipment to assist planting can significantly accelerate the production process. As an important economic crop, potatoes are supported by a variety of mechanical equipment, among which land ditching equipment is particularly effective.

[0003] The existing patent CN215957081U discloses a trenching device for potato planting, including a traction rod, a mounting plate, and a cutter. The traction rod includes a first rod, a second rod, and an elastic pull rod assembly. The first rod is mounted on an external power source, and the second rod is inclined upwards on the mounting plate. The first and second rods are rotatably connected. The two ends of the elastic pull rod assembly are hinged to the sides of the first and second rods and located below them, providing tension. The cutter is mounted on the bottom surface of the mounting plate. This invention, with its connecting rod, first and second rods, and elastic pull rod assembly, allows the mounting plate to tilt upwards when the cutter encounters a large stone, thus avoiding the stone and reducing damage. However, the existing trenching cutter cannot be adjusted in width according to requirements, and disassembly is difficult due to the bolt fixing, making disassembly and adjustment inconvenient and complex, time-consuming, and labor-intensive.

[0004] Therefore, in view of the above-mentioned problems that existing trenching tools are complicated to disassemble and cannot adjust the trenching spacing according to needs, which have certain limitations and are not flexible enough, a trenching device for potato planting can be designed. With trenching tools that are easy to disassemble, it saves time and effort, and the spacing between two trenching tools can be adjusted according to needs, which is more flexible and has high practicality. Utility Model Content
