AI Technical Summary

Technical Problem

Existing deep tillage machines suffer from high resistance and severe straw dragging when deep tilling and ridging in compacted fields and fields with a lot of straw, and the cost is high, which cannot effectively improve the efficiency of straw return to the field.

Method used

The lever-type anti-trapping deep tillage plow, combined with a lever-type deep tillage machine, plowshare, and straw cutter, is designed into a special structure and connected to the rear of the tractor. Through the lever action, it reduces resistance, achieves deep soil loosening and straw cutting, and avoids trapping.

Benefits of technology

It reduces tractor fuel consumption, improves the efficiency of straw return to the field, reduces straw hauling, enhances soil loosening, and lowers costs, making it suitable for widespread application.

Abstract

A lever type anti-dragging pile deep loosening plow, comprising a tractor, a hydraulic traction suspension bracket, a lever type deep loosening machine, a straw cutting knife and a plow share, the bracket is connected with the lever type deep loosening machine through bearings at both ends of the front position below the bracket, a plurality of soil loosening cutters are uniformly distributed along the length direction of the soil loosening shaft, a plurality of soil loosening sharp cutter bodies are fixedly arranged on each soil loosening cutter along the radial direction, the cutting edges are directed to the front earth direction and the cutter heads are outward, a plurality of plow legs are fixedly connected and arranged on the rear beam below the bracket along the length direction of the beam, a plow share is fixedly connected to the lower leg of each plow leg, and a straw cutting knife is fixedly connected to the upper part of each plow leg. The combination of the lever type deep loosening machine, the plow share and the straw cutting knife and the reasonable structure solve the problem of straw and leaf dragging pile and the problem of hard ground unable to be deeply loosened, which is very meaningful for agricultural production and is particularly suitable for popularization and application in the field and has a very broad market prospect.
