Compacting intertillage weed extractor

Abstract

The invention relates to a compacting intertillage weed extractor. The compacting intertillage weed extractor comprises traction equipment, a machine frame connected behind the traction equipment, a compacting wheel, a soil leveling plate group and a scratching shovel group, wherein the compacting wheel, the soil leveling plate group and the scratching shovel group are sequentially mounted on the machine frame from front to back, the soil leveling plate group comprises a plurality of soil leveling plates which are continuously arranged in the left-right direction, and the front ends of the soil leveling plates are connected with the machine frame through transverse springs; and the scratching shovel group comprises a plurality of scratching shovels arranged in the left-right direction, the scratching shovels are correspondingly located right behind the soil leveling plates, and the soil leveling plates are connected with the scratching shovels right behind the soil leveling plates through lever devices. According to the compacting intertillage weed extractor, the leveling plates and the scratching shovels are connected through the lever devices, the scratching shovels are driven to move up and down by means of the friction resistance difference of plants and soil on the soil leveling plates, and when the leveling plates slide on crop plants, the scratching shovels tilt to be higher than the ground, so that the scratching shovels are prevented from touching and damaging crops; and when the land leveling plates slide on the soil between two rows of crop plants, the scraping shovels are pushed to fall down and be inserted into the soil, and intertillage soil loosening and hoeing between the rows are carried out.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a compaction and intertillage weeder used for compaction, intertillage loosening and weeding. Background technique [0002] In the process of planting crops, in order to prevent the soil from being too loose and to prevent the loss of soil moisture by evaporation, field suppression is required. When the seedlings grow too vigorously, the suppression also plays a role in controlling the vigorous growth of the seedlings and promoting their transformation from flourishing to strong. For crops such as winter wheat, in the process of seedling suppression, it is often necessary to combine intertillage loosening and weeding to create a reasonable tillage layer with upper pine and lower solid and prevent weed damage. The predecessors paid more attention to the research and development of field suppression technology and machinery after soil plowing and sowing. There are f...

AI Technical Summary

Problems solved by technology

At present, there are few reports on the agricultural machinery that can realize the functions of compaction, cultivating loose soil and weeding at the same time.

In addition, because the row spacing of different crops is not uniform, and the row spacing of some crops is relatively small, when using agricultural machinery with fixed loosening and weeding devices for field operations, there will often be misalignment between the loosening shovel and the row, not only It affects the quality of loose soil and weeding, and the loose soil shovel will dig, hook and accidentally injure crop plants, causing unnecessary losses to crop production, affecting crop yield and grower income
