Description

Technical Field

[0001] This utility model relates to the field of micro-tillers, and in particular to a multi-enhanced blade assembly for micro-tillers. Background Technology

[0002] A mini tiller is a small agricultural machine, mainly composed of working parts, a frame, a transmission system, and a power unit. It uses mechanical equipment to till, loosen, and break up the soil, thereby improving soil aeration and water retention, providing a better environment for plant growth. Currently, during operation, the mini tiller's blades may affect its working condition and reduce actual tillage efficiency due to the complex composition of some soils, containing more debris and hard stones. Additionally, with prolonged use, the angle adjustment mechanism of the mini tiller may lose its accuracy over time, making adjustments difficult for operators. Utility Model Content

[0003] This invention addresses the problems existing in the prior art by providing a multi-enhanced blade assembly specifically for micro-tillers. By optimizing the angle adjustment components of the micro-tiller and simultaneously improving the structure of the blade disc itself, the aforementioned problems can be solved.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-enhanced blade assembly for micro-tillers, comprising:

[0006] Install beams;

[0008] The upper end of the hydraulic output cylinder is fixedly connected to the mounting beam, and the lower end of the hydraulic output cylinder is configured to cooperate with the angle adjustment component. The hydraulic output cylinder provides auxiliary support to the angle adjustment component.

[0009] The upper fixed bracket is fixedly installed on the upper side of the angle adjustment component;
