Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with specific embodiments, so that those skilled in the art can understand.
[0034] like figure 1 , 2 The shown rape shovel-shovel combined cultivator includes a frame 13, a shovel-type soil preparation device 9, a furrow front plow 6 installed at the front bottom of the frame 13, and a furrow rear plow installed at the rear bottom of the frame 13. Plow 10, the level soil dragging plate 12 installed in the frame 13 rear and the three-point suspension device 25 installed in the frame 13 front, and the depth-limiting device 2 positioned at the three-point suspension device 25 both sides and installed in the frame 13 front Middle plow 1 in the middle of the bottom. Among them, the frame 13 includes two side plates 13.6, a front bottom beam 13.3 supported on the front end of the bottom of the two side plates 13.6, a middle top beam 13.4 supported on the top of the middle part of the two side p...

The invention discloses a rape shovel-shovel combined tillage machine, which comprises a frame, a shovel-shovel type soil preparation device, a furrow-opening front plow installed at the front bottom of the frame, and a furrow-opening rear plow installed at the rear bottom of the frame 1. The leveling drag plate installed at the rear of the frame and the three-point suspension device installed in front of the frame, as well as the depth-limiting device located on both sides of the three-point suspension device and the middle plow installed in the middle of the front bottom of the frame; the shovel The shovel-type soil preparation device consists of several groups of shovels and a crankshaft-like power transmission device. The shovel based on the crankshaft unit, because of its anthropomorphic feature that it only turns the farrow backwards and does not move the farrow laterally, leaves no furrows and plow bottoms after plowing. The curve of the curved surface of the shovel is a sine curve, which reduces the resistance of the shovel into the soil during operation, effectively reduces the slippage of the tractor wheels, and improves the fuel utilization rate.
Description
technical field [0001] The invention relates to a combined cultivator in agricultural machinery, in particular to a rape shovel-shovel combined tiller. Background technique [0002] Rapeseed is an important oil crop in my country, and land preparation is particularly important as the primary link in rapeseed planting. With the acceleration of my country's agricultural mechanization process and labor shortage, the degree of mechanized planting of rapeseed is increasing year by year. In 2018, the national level of machine-cultivated rapeseed was 82.3%, and the area of machine-cultivated land was 5391.29 thousand hectares. [0003] According to different regions, tillage and rotary tillage are the commonly used tillage methods for rape planting in my country. The traditional rotary tillage operation has good quality of crushed soil and surface leveling after tillage, but the plowing depth is shallow and the operation consumes a lot of power. In tillage operations, the plow la...
