Energy-saving efficient rotary tiller

Abstract

The invention relates to an agricultural tool, namely an energy-saving efficient rotary tiller. The energy-saving efficient rotary tiller comprises a traction frame (1), a cross shaft (2), a cutter disc (5), a blade (6) and a transmission component which is connected with a power output shaft of a tractor. The invention is characterized in that an included angle alpha between the straight line of the cutting edge side of the blade (6) or the midline (10) of the blade (6) and the radial line (9) from the center of an installation hole (8) at the inner end of the blade (6) to the center of the cutter disc (5) is between 60 degrees and 80 degrees. The installation angle of the blade is changed, the cutting performance is improved, the blockage of weeds is avoided, and the cutting effect of the cutter disc is exerted adequately. In addition, a strengthening frame is arranged above a rack, so the rigidity and stability of the tool are improved. On the premise of ensuring tilling depth, the power consumption is greatly lowered, and the operation efficiency of the tool is improved. The invention has the characteristics that the energy-saving efficient rotary tiller has a simple structure, the cost is low, the installation is convenient, and the like. The energy-saving efficient rotary tiller has considerable market prospects.

Description

technical field [0001] The invention relates to an agricultural implement, namely an energy-saving and high-efficiency rotary tiller. Background technique [0002] At present, the use of rotary tillers to loosen the soil has become a routine operation in northern dry-farming agricultural areas. The traction frame of the rotary tiller is connected with multiple cutterheads in series through a horizontal axis, and each cutterhead is equipped with multiple blades. The power output shaft of the tractor drives the horizontal shaft, the cutter head and the blade to rotate through the transmission parts, and breaks up the soil in the plow layer during the advance. But, the power consumption of existing rotary cultivator is very big, and operation cost is higher, and its reason mainly is that the installation method of cutterhead and blade is unreasonable. Existing blades are all installed along the radial line of the cutter head, that is, the side line of the blade edge or the cen...

Problems solved by technology

In addition, the adjustment range of the existing depth-limiting mechanism is relatively small, and the cutter head rarely participates in cutting, and the blade works close to the periphery of the cutter head. Although the blade rotary cutting diameter is larger and consumes more power, the plowing depth is not too large

Therefore, the working width of a rotary tiller matched with a 120-horsepower tractor generally does not exceed 3 meters, and the fuel consumption is high and the working efficiency is very low.
