Abstract
Description
Technical Field
[0001] The present application relates to the field of micro-tillage machines, and in particular to a micro-tillage machine that is easy to adjust. Background Art
[0002] A micro-tiller is a type of agricultural machinery powered by a small diesel or gasoline engine. It has the characteristics of light weight, small size, and simple structure. The micro-tiller can travel freely in the field, which is convenient for users to use and store. It saves the trouble of large agricultural machinery being unable to enter mountain fields. It is the best choice for farmers and consumers to replace ox plowing. It is often used for grape cultivation. When using the current micro-tiller, after the machine body is connected to the power supply, the control handle is used to control the machine body to move in the planting field, and the digging shovel at the bottom of the machine body is used to loosen the ground.
[0003] With regard to the above-mentioned related technologies, the inventors believe that when conventional micro-tillage machines dig soil for different plants, the depth of digging required by the micro-tillage machines varies due to the influence of soil, plants and terrain. When adjusting conventional digging shovels, the angle of the digging shovel is often directly adjusted with the help of threaded rods, which makes the angle of the digging shovel close to perpendicular to the ground, thereby increasing the friction between the digging shovel and the ground. In the process of loosening relatively hard soil, the digging shovel is easily subjected to greater pressure and is difficult to move or even damaged.
[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
