Ditching device

Abstract

The invention relates to a ditching device which comprises a mounting frame, a sliding knife part, a seed guide pipe and a grinding wheel, the sliding knife part, the seed guide pipe and the grindingwheel are sequentially mounted below the mounting frame from left to right, the sliding knife part comprises a sliding knife body and soil baffles, and the soil baffles are located on the two side faces of the sliding knife body; the upper end of the seed guide pipe penetrates through the mounting frame; the grinding wheel comprises a grinding wheel body, a first connecting rod, a second connecting rod and a spring, one end of the first connecting rod is connected with the grinding wheel body, the other end of the first connecting rod is connected with the mounting frame, one end of the secondconnecting rod is connected with the middle of the first connecting rod, and the other end of the second connecting rod penetrates through the spring and the mounting frame. The ditching device is provided with the seed guide pipe and the grinding wheel, seeding and tamping operation can be performed while ditching operation is performed, the uniformity of the seeding depth of crop seeds and thecompactness of seedbed soil are ensured, the seeding efficiency is improved, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of seeders, and in particular relates to a ditching device. Background technique [0002] Conservation tillage is a new type of tillage technology, which mainly includes four basic contents of stubble mulching, no-tillage fertilization and seeding, pest and weed control, and subsoiling. Conservation tillage can reduce plowing and harrowing and return crop residues such as straw and root stubble to the field, which is conducive to protecting soil structure, increasing soil organic matter content, and reducing soil loss. It is an important way to achieve sustainable agricultural development. [0003] With the development and promotion of conservation tillage techniques and models, the intertillage operations in the crop planting process are gradually being simplified. In the process of no-tillage operation, there are a lot of straw residues on the surface and the root-soil complex formed by plant roots and so...

AI Technical Summary

Problems solved by technology

The ditch opener is the main working part of the no-tillage seeding and fertilizing machine, and its working quality directly affects the quality of sowing and fertilization. However, most of the agricultural machinery and equipment now use different devices to complete the ditching, sowing and filling operations, and the operation is complicated. , inconvenient for personnel to operate
