Seed ditch cleaning device for no-tillage seeding

Abstract

The invention relates to the field of agricultural mechanical equipment, and provides a seed ditch cleaning device for no-tillage seeding. The seed ditch cleaning device comprises a rack, and furthercomprises a corrugated cutting disc, a furrow opener, a cleaning mechanism and a seed guide pipe which are sequentially fixed below the rack from the front end of the rack to the rear end of the rack;the cleaning mechanism comprises a grass clearing disc and a grass lifting shovel arranged between the grass cleaning disc and the seed guide pipe; the free end of the grass lifting shovel is twistedtowards a preset direction so as to guide sundries shoveled by the grass lifting shovel from seed ditches to slide in the preset direction, and the preset direction is the right side or the left sideof the rack; and the grass clearing disc is rotatably fixed below the rack through a connecting piece, and a plurality of elastic teeth are arranged on the periphery of the grass clearing disc in thecircumferential direction of the grass clearing disc and used for throwing the sundries scooped up by the grass lifting shovel out of the seed ditches. According to the seed ditch cleaning device, byutilizing centrifugal force generated when the elastic teeth rotate along with the grass clearing disc, the sundries such as straw and residual films shoveled by the grass lifting shovel from the seed ditches are thrown out of the seed ditches, and the phenomenon that seeds cannot emerge due to the residual sundries in the seed ditches can be avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to a seed ditch cleaning device for no-tillage sowing. Background technique [0002] No-till sowing is to directly sow seeds with straw covering the ground without plowing. If the moisture content of the straw is high, the soil is relatively moist, or the amount of straw is relatively large, some straw cannot be cut by the disc knife but pressed into the seed ditch during the ditching process of no-tillage sowing, which may cause the seed tube The discharged seeds fall on the stalks pressed into the seed ditch, so that the seeds are lifted by the stalks and cannot contact the soil, and then cannot emerge. In addition, there is a large amount of residual film in the soil plow layer in some areas, and the seeds discharged from the seed introduction tube may fall on the residual film, which will cause the seeds to fail to emerge and affect the emergence rate. ...
