Description

Technical Field

[0002] Cultivation machinery mainly refers to machinery used for weeding, loosening soil, breaking topsoil, building soil and ridges during the growth of crops, or completing the above operations and fertilizing at the same time, including full-scale cultivators, inter-row cultivators and special cultivators. Full-scale cultivators are used for seedbed preparation operations including pre-sowing land preparation, fallow land management, and blending of fertilizers and chemicals. Inter-row cultivation operations of crops include loosening soil, breaking topsoil, thinning, weeding, topdressing, and inter-row trenching and soiling. Some special cultivators are used for special operations in orchards, tea gardens, and rubber plantations.

[0003] When the existing cultivator is in use, the plow blade is generally fixed to the surface of the frame by bolts. When working, the plow blade is driven by the movement of the cultivator to cultivate. Due to the erosion of rain, mud and soil, the bolts are easily rusted and stuck in the frame, which makes it difficult to disassemble the plow blade for maintenance when it is needed, reducing the maintenance efficiency. In addition, the existing cultivator needs to adjust the spacing between the plow blades according to the situation. The traditional adjustment method is to open equally spaced through holes on the surface of the frame, arrange the plow blades at equal intervals and then fix them with bolts. However, each adjustment requires the plow blades to be completely disassembled, which is labor-intensive and inconvenient to use. Utility Model Content
