Device for preventing seed bouncing

Abstract

The invention discloses a device for preventing seed bouncing. The device is composed of a cam shaft mechanism, a ditch building mechanism, a pressing mechanism, a seed discharge pipe, and a support plate. The ditch building mechanism and pressing mechanism are respectively arranged on the cam shaft mechanism and the support plate; and the seed discharge pipe is fixed on the support plate. Before sowing, the device can build a ditch. After sowing, the soil is pressed immediately. Thus bouncing and rolling of seeds are effectively controlled. The ditch building mechanism comprises a ditch building wedge, which can well keep the ditch shape after ditching, so that discharged seeds can stably fall on the seedbeds. The bottom press plate of the pressing pedal of the pressing mechanism is provided with grooves, which can prevent the bouncing and rolling of seeds. The slide bars of the ditch building mechanism and the pressing mechanism are both provided with through holes in the axial direction. Under the assistance of a cylindrical compression spring, the strength of ditch building and pressing can be adjusted, thus the sowing quality is improved, the crop output is increased, the labor strength of sowing is reduced, and the device is worthy for promotion.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a seed anti-bounce device. Background technique [0002] Sowing is an important link in agricultural production operations, and the quality of sowing has a vital relationship with the seed meter. The researchers' research on the seed metering device has been very mature, and the sowing quality should be getting higher and higher. However, in the actual sowing process, the sowing quality is often difficult to meet the expected requirements. The researchers found that the moment the seeds leave the seed meter and fall into the seed bed, the seeds collide with the soil of the seed bed, which will cause a certain degree of bouncing and rolling. The soil flow after mulching moves together, which again leads to differences in the depth of the seeds on the seed bed. This process will cause uneven distribution of seeds on the seed bed and inconsistent sowing depth, result...
