Description

Technical Field

[0001] The utility model belongs to the field of agricultural equipment, in particular to an electric rotary tiller. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. With the development of agricultural mechanization, the application of rotary tillers has become more and more extensive. A rotary tiller is a type of agricultural machinery that can be used in conjunction with a tractor to complete plowing and harrowing operations. It has the characteristics of strong soil crushing ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, facilitating the operation of the seeder and providing a good seed bed for later sowing. According to the configuration of its rotary tiller blade shaft, it is divided into three categories: horizontal axis type, vertical axis type and inclined axis type.

[0003] The Chinese patent with publication number CN118235547A discloses an agricultural planting rotary tiller, including a mounting plate, the bottom of the mounting plate is fixedly connected to a connecting plate 1, two connecting plates are provided, the side of the connecting plate 1 is fixedly connected to a rotary tillage mechanism, the outer side of the connecting plate 1 is fixedly connected to a connecting plate 2, the end of the connecting plate 2 away from the connecting plate 1 is fixedly connected to an extrusion mechanism, the end of the extrusion mechanism away from the connecting plate 2 is fixedly connected to a fixing rod, and the end of the fixing rod away from the extrusion mechanism is fixedly connected to a compacting mechanism.

[0004] In the above patent, after the soil is plowed up by the plow blade, a large amount of soil often adheres to the surface of the plow blade. If it cannot be removed in time, it will increase the resistance of the subsequent plow blade to the soil. Therefore, a new device needs to be designed. Utility Model Content
