Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a row tiller. Background Technology

[0002] Inter-row tillage machinery mainly refers to machinery used for weeding, loosening soil, breaking up compacted topsoil, ridging, or fertilizing during crop growth. It includes full-length tillers, inter-row tillers, and special-purpose tillers. However, common inter-row tillers cannot adjust the blade spacing according to the row spacing required for different crop types, which greatly reduces the practicality and applicability of the tiller. Furthermore, when encountering soils of varying hardness, the quality and uniformity of soil loosening may not meet the user's needs.

[0003] For example, the crop inter-row tillage and weeding machine disclosed in announcement number CN101926238A mainly consists of a body of various applicable shapes, handles and storage batteries, electric motors or small engines, tillage rollers or tillage shafts, wherein the tillage rollers and tillage shafts have various special blades that can be moved up and down.

[0004] As can be seen from the above-mentioned publicly available solutions, when the tiller is working, it is impossible to adjust the overall width of the blades according to different row tools, which reduces the scope of application and reduces its practicality. Furthermore, when weeding and loosening soil by using tiller blades, the quality and uniformity of loosening soil may be reduced when the soil hardness varies. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an inter-row cultivator. This inter-row cultivator, through the setting of an adjustment rod, adjustment hole, and adjustment seat, allows the tillage component to freely adjust the distance between the two weeding blades according to the actual row spacing, thereby greatly improving the practicality and applicability of the cultivator. Furthermore, through the setting of loosening teeth and the soil-dividing plates set on the loosening teeth, it can automatically divide and loosen the raised soil, greatly improving the quality and uniformity of soil loosening by the cultivator.

[0006] To solve the above problems, the present invention adopts the following technical solution.
