Four-wheel drive rotary cultivator

Abstract

The invention provides a four-wheel drive rotary cultivator, and solves the problems that the height of a prior rotary cultivator is fixed and cannot be adjusted, the rotary cultivator is driven by two wheels, the climbing capacity is not enough at pot hole places, the rotary cultivator falls into the pot holes easily, and the prior used blades are generally integrated. When the four-wheel drive rotary cultivator provided by the invention is in use, a front walking shaft and a rear walking shaft are connected together by chains, so that four-wheel drive is realized, and the phenomena that theclimbing capacity is not enough at pot hole places and the rotary cultivator slips easily can be avoided; two ends of a rotary cultivator shaft are directly driven by a double-output-shaft gasoline engine, and the two ends of the rotary cultivator shaft are directly connected by adopting double output shafts, so that enough power is ensured, a speed adjusting function is achieved, and the speed adjustment is convenient; when the height needs to be adjusted, the height is directly adjusted by a first lifting column and a second lifting column; a rotary cultivator is connected with a connectingseat through fixing bolts, so that convenience for later disassembly and maintenance is provided; and blades are designed by adopting a split type, so that when the rotary blades are required to be sharpened, the rotary cultivator blades can be removed through fixing pieces, sharpening is carried out separately, and great convenience is provided to sharpening operators.

Description

technical field [0001] The invention relates to the technical field of rotary tillers, in particular to a four-wheel drive rotary tiller. Background technique [0002] The rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. [0003] With the in-depth popularization of modern agricultural mechanization, in production, it is necessary to complete the plowing, sowing, and fertilization at one time instead of completing the work in batches in the past. Therefore, it is required that the rotary tiller can be stretched up and down to cooperate with other tools to complete the operation. The rotary tiller The up and down expansion and contraction can also meet the requirements of different crop sowing depths. [0004] The rotary tillers currently on the market are separate components and the depth of the cultivated land is ...
