Anti-blocking opener and no-tillage drill planter comprising same

Abstract

The invention discloses an anti-blocking opener and a no-tillage drill planter comprising the same and belongs to the field of agricultural machinery. The anti-blocking opener comprises a disc openingunit and a planting opening unit; an opening blade is fixed in front of an opening shovel body, the rear position of the upper end of the opening shovel body is provided with a round seed planting channel and a round fertilizer planting channel which are arranged side by side; the lower end of a planting pipe is fixedly mounted inside the round seed planting channel, and the lower end of a fertilizer planting pipe is fixedly mounted inside the round fertilizer planting channel; the front position of the upper end of the opening shovel body is provided with a blade pressing air cylinder for exerting downward pressure on the front portion of the opening shovel body. The anti-blocking opener has the advantage that the disc opening unit and the planting opening unit which both have an openingfunction are combined, the disc opening unit can open a planting furrow and cut off the roots of previous crops in the middle of the planting furrow to achieve pre-planting preliminary opening, so that the planting opening unit only needs to turn up a small amount of soil for achieving planting during an opening planting process.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an anti-blocking opener and a no-tillage drill using the anti-blocking opener. Background technique [0002] In traditional farming, after plowing and land preparation, the opener ditches and sows seeds in the loose plow layer, the ditching resistance is small, and the sharpness of the cutting edge has no obvious impact on the forward resistance of the opener. However, in no-tillage stubble land, the surface is solid and covered with a large amount of straw, it is difficult for the opener to enter the soil, and the resistance is large, so it needs good performance of breaking stubble into the soil. It should have a sharp edge to reduce the forward resistance of the opener and reduce the power consumption of the tractor; the surface soil disturbance is small to reduce the mixing of dry and wet soil in the upper and lower layers of the soil, and create a loose seedbed that is ...
