Combined knife blade type terrain-self-adaptation furrowing machine

Abstract

The invention discloses a combined knife blade type terrain-self-adaptation furrowing machine, which comprises a frame, a furrowing mechanism, a terrain detecting device and a depth limiting and regulating device, wherein the furrowing mechanism, the terrain detecting device and the depth limiting and regulating device are all mounted on the frame; the terrain detecting device is mounted on the frame and is used for detecting the real-time terrain state of a ground surface to be furrowed by the furrowing machine; a knife-blade included angle regulating device is mounted on the frame and is further used for regulating the opening-closing angles of combined furrowing knife blades according to the demand of a user; the depth limiting and regulating device comprises a first depth limiting device and a second depth limiting device; the depth limiting and regulating device is used for regulating the heights of the first depth limiting device and the second depth limiting device based on thedetection result of the terrain detecting device. The combined knife blade type terrain-self-adaptation furrowing machine is used for avoiding the problems that the furrowing depth is not uniform anda furrow dam is unsymmetrical, which are caused as the ground surface is uneven, guaranteeing the consistency of the furrowing depth and providing convenience for later drainage and irrigation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a combined blade type terrain self-adaptive ditching machine. Background technique [0002] In the field of agricultural water conservancy and in the process of agricultural production, in order to meet the requirements of agronomic ditching and water-saving irrigation, ditching operations need to be carried out frequently. In the past, manual ditching was usually used. However, manual ditching is labor-intensive and the quality of the ditch Low. With the improvement of mechanization level, the appearance of ditching machine has replaced manual work, which improves work efficiency and reduces people's labor intensity. [0003] However, as far as the current situation is concerned, there are still some problems with the ditching machine. For example, on the one hand, the ditching type, depth and width of the ditching machine are fixed and cannot be adjusted, which ...

AI Technical Summary

Problems solved by technology

[0003] However, as far as the current situation is concerned, there are still some problems with the ditching machine. For example, on the one hand, the ditching type, depth and width of the ditching machine are fixed and cannot be adjusted, which causes the user to purchase a variety of ditching machines to complete. Different ditching operation requirements, so the production cost of the user and the time to replace the ditching machine will be greatly increased; secondly, the ditching machine is to cut and break the soil clods through the ditching knife, and loosen the land to realize the ditching operation, but at present The form of the ditching knife is fixed, resulting in different degrees of porosity for different soils, which in turn affects the ditching effect; and the soil after loosening remains too much at the bottom of the ditch, resulting in insignificant ditching effects; When working on land with poor flatness, the ditch will be uneven, which will affect the drainage and irrigation in the later stage; obviously, the current problems of the ditching machine limit the popularization and application of the ditching machine in a wide range of areas
