Problems solved by technology

According to the measurement and calculation results in the field, it can be seen that when this type of deep loosening shovels deep loose soil, the loosening coefficient is only about 0.3, and vertical furrows are left in the loosened soil layer, which are easy to cause moisture and soil and water drain

Embodiment 1

[0031]According to the invention, the space curved surface of the subsoiling shovel can be divided into two types: left-inclined and right-inclined, the length of the shovel handle is a=250mm, the arc length of the working surface is ∩s=300mm, the width of the subsoiling shovel is d=150mm, and the thickness of the blade is b=25mm. The space surface subsoiling shovels are symmetrically arranged according to the rules, and are symmetrically installed in pairs on the frame of the subsoiling machine with a working width of 1300mm (2 rows) ~ 3900mm (6 rows). The installation position is aligned with the furrows, and the implements are driven by 80-120 horsepower tractors to carry out inter-row subsoiling operations under conservation tillage conditions. The forward speed of subsoiling implements is 4km / h. The results of multiple measurements are: the depth of subsoiling can be adjusted by adjusting the positioning hole 4, the adjusted depth ranges from 250mm to 400mm, the stability ...

Embodiment 2

[0033] The length of the shovel handle is a=275mm, the arc length of the working surface ∩s=350mm, the subsoiling shovel width d=165mm, and the blade thickness b=27.5mm. Other conditions are identical with embodiment 1.

[0034] The results of multiple measurements are: the stability of tillage depth can reach 92%, and the broken soil rate can reach 85%.

Embodiment 3

[0036] The length of the shovel handle is a=300mm, the arc length of the working surface ∩s=400mm, the subsoiling shovel width d=180mm, and the blade thickness b=30mm. Reduce the distance between the two subsoiling shovels so that the distance is between 100mm and 150mm, and install them symmetrically on the main beam in pairs, which can achieve the effect of all-round subsoiling. The implements are driven by tractors with more than 120 horsepower to carry out inter-row subsoiling operations under conservation tillage conditions, and the forward speed of subsoiling implements is 4km / h. The results of multiple measurements are: the stability of tillage depth can reach 93%, and the broken soil rate can reach 86%.

Abstract

The invention relates to a space curved face type subsoiler which belongs to the technical field of agricultural machinery. The upper end of a blade is fixedly connected with a shovel handle provided with adjusting positioning holes, while the lower end is fixedly connected with a shovel point. The included angle theta of a shovel edge is 45-55 degrees. Four adjusting holes are arranged on a same line. The front part of the shovel point is triangular cone-shaped, and the rear part is cuboid. The shovel edge is a space curved line which can be placed in a spatial three-dimensional right-angled coordinate system. The vertical projections of the shovel edge on a plane YOZ parallel to the forwarding direction of the subsoiler and a plane XOZ vertical to the forwarding direction of the subsoiler are respectively a forerake soil cutting curve MN and a side inclined soil lifting curve PQ. The shape of the blade is obtained by negatively extending the shove edge along the Y-axis. According to the subsoiler, the service life of the subsoiling part is prolonged, transverse vibration of the whole machine is reduced, the soil breaking effect is improved, the effective deep scarification volume is increased, the operational efficiency is improved, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a space curved subsoiling shovel. Background technique [0002] There are roughly three types of subsoiling parts used by various subsoilers on the market, namely chisel type subsoiling shovels, inclined column type subsoiling shovels and all-round subsoiling shovels. Three different subsoiling shovels are installed on the main beam of the subsoiling machine in different arrangements according to different working methods. The method can be used for both interval subsoiling and all-round subsoiling, and the all-round subsoiling shovel is only used for all-round subsoiling. [0003] The chisel type subsoiling shovel uses the chisel tip (shovel head) on the knife rod installed vertically in the horizontal and vertical planes to apply unlimited extrusion to the soil to loosen the soil, but in the deep layer of the soil, the vertical knife The rod exerts ...
