Rotary cultivator

Abstract

The invention provides a rotary cultivator. The rotary cultivator comprises a rotary cultivating device, a walking device, a pressing device, a power system and a control system, wherein the rotary cultivating device is arranged at the tail end of the walking device; the pressing device is arranged at the tail end of the rotary cultivating device; the power system is connected with the control system; both the power system and the control system are arranged on the rotary cultivating device; the rotary cultivating device comprises a first cutter shaft and a second cutter shaft; the first cutter shaft and the second cutter shaft are connected with the power system through the transmission mechanism. The rotary cultivator has the beneficial effects that a fixing frame is adopted, the rotarycultivating device is suspended on the walking mechanism through an upper pull rod, a lower pull rod and a lifting device, and the ascending and descending of the rotary cultivating device are controlled through the lifting device in order to prevent a rotary cultivation tool from sinking and ensure that the rotary cultivating depth is always constant when the rotary cultivating device works on uneven ground; the first cutter shaft and the second cutter shaft are arranged one after the other, so that the power consumption of the whole rotary cultivator is lower, upper cultivated soil is prevented from being mixed with lower raw soil, the production environment of crops is ensured, and the operation cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rotary tiller. Background technique [0002] The rotary tiller has the dual functions of plowing and harrowing. After plowing, the soil on the field surface is loose and broken, and the surface is flat. [0003] The so-called rotary tiller usually refers to a rotary tiller with a horizontal axis of the rotary tiller, also known as a horizontal rotary tiller, and it is also the most widely used tillage machine in my country. When this type of implement works, it relies on the rotation of the rotary tiller installed on the cutter shaft and the compound movement of the unit to complete the field tillage operations such as soil crushing and surface leveling. Its operating depth is an important performance indicator, usually the operating depth is generally 8-15cm, and the operating depth is limited by the maximum turning radius of the rotary tiller, the ...

AI Technical Summary

Problems solved by technology

Its operating depth is an important performance indicator, usually the operating depth is generally 8-15cm, and the operating depth is limited by the maximum turning radius of the rotary tiller, the position of the lowest point of the cutter shaft support such as the transmission box and the support plate, and the matching Due to the influence of power, deeper operations cannot be completed. Long-term use of rotary tillers for plowing operations will make the soil plow layer shallower, and the soil hardening layer will rise, which affects the growth of crops.

[0004] At the same time, when the rotary tiller is performing rotary tillage on relatively soft or wet land, the rotary tiller blades often sink or pry up until the handle of the rotary tiller sinks into the soil, causing the rotary tiller to stop working; Inconsistent depth of rotary tillage for the growth of crops; the soil after rotary tillage has different sizes of land, which is not conducive to the planting of seedlings

At the same time, when cultivating land with soft soil, the wheels of the rotary tiller are easy to sink into the soil, it is difficult to get the rotary tiller out, and the complex structure of the rotary tiller is not easy to disassemble and transport, resulting in a lot of labor for the operators
