AI Technical Summary

Technical Problem

Traditional soil tilling equipment is difficult to meet the multi-level needs such as deep turning, sieving soil, fine crushing and flat ground at the same time, resulting in low operating efficiency and difficult to adapt to diversified soil and crop planting conditions.

Method used

A composite soil-turning heavy rake is designed, including deep rotary tillage components, soil-turning screen components and shallow rotary tillage components. Through the cooperation of these components, multiple steps such as deep tillage, crushing and raking soil can be completed in one operation, and a heavy rake synchronous lift control system is used to achieve height adjustment and adaptability.

Benefits of technology

It improves operating efficiency, can effectively decimate deeper soil, improve soil fineness, ensure ground flatness, and adapt to different soil conditions and crop needs.

Abstract

The invention discloses a composite soil turning heavy harrow and a heavy harrow synchronous lifting control system, belonging to the technical field of agricultural machinery. The composite soil turning heavy harrow comprises a connecting frame, under which a deep rotary tillage assembly, a soil turning screen assembly and a shallow rotary tillage assembly are fixed in sequence; the soil turning screen assembly comprises: the upper end of the plow is fixedly connected to the connecting frame, the front end of the soil screening rod is fixedly connected to the rear side of the plow, the front part of the soil screening rod has an upper convex part, the rear part has a lower convex part, and the rear end of the soil screening rod has a harrowing part extending upward; the soil turning screen assembly is located above the lower convex part, and the soil turning screen assembly and the harrowing part are connected to the connecting frame through a floating assembly. The present invention uses a deep rotary tillage assembly to turn out the soil at a deeper depth, and the soil turning screen assembly effectively guides and preliminarily screens larger soil blocks and debris through the cooperation of the plow and the soil screening rod, and the shallow rotary tillage assembly further crushes larger soil blocks and debris with a small torque and high speed operation, and the harrowing part smoothes the soil, and multiple steps such as deep tillage, crushing and harrowing can be completed in one operation, thereby improving the operation efficiency.
