AI Technical Summary

Technical Problem

Existing soil processing devices require significant tractor traction, leading to increased slip and diesel fuel consumption, especially in severe soil conditions, and lack effective mechanisms for maneuverability and weight distribution.

Method used

An energy storage system, such as a hydraulic cylinder, is integrated between the cultivation device and the drawbar to improve tractor traction, allowing weight transfer from the front to the rear axle, and a ball or cross joint is used to connect the three-point tower and drawbar, enabling better maneuverability and slip reduction.

Benefits of technology

This solution significantly reduces slip and diesel fuel consumption while maintaining effective maneuverability and weight distribution, especially in uneven terrain, by optimizing weight transfer and traction.

Abstract

The invention relates to a mounted or trailed soil cultivation implement (1) with a large working width, comprising a chassis (2) and a frame (4) having soil cultivation tools (3), with a drawbar (5) with attachment device (6) for connection to the three-point linkage of a tractor with top link (7) and lower links (8).According to the invention, at least one energy storage device (10) engages directly or indirectly between the mounting device (6) and the drawbar (5), which serves to generate a tractive force in the top link (7) of the three-point linkage, that the energy storage device (10) is designed as a hydraulic cylinder (20), wherein the hydraulic cylinder (20) is equipped with at least one hydraulic accumulator, and that the joint (9) between the three-point tower (11) and the drawbar (5) of the frame (4) is designed as a ball or universal joint to transfer weight from the implement to the tractor, thereby improving the traction of the tractor and reducing slippage of the tractor's rear wheels.
