Wheel disc type seed fertilizer dibbler

Abstract

The invention provides a wheel disc type seed fertilizer dibbler, which includes a high pressure shaft tube fixed on a mounting plate, a wheel disc shaft fixedly sealing one end of the high pressure shaft tube, and a seed fertilizer wheel disc. A spray hole is arranged at the bottom of the high pressure shaft tube, a valve plug is mounted in the spray hole, and a radial valve compression spring is arranged at the valve plug. A plurality of liquid fertilizer passages located on the same circumferential plane as the valve plug are evenly distributed on the seed fertilizer wheel disc, the outer end of each liquid fertilizer passage communicates with a fertilizer spray pipe, a valve push rod is mounted in the fertilizer spray pipe, and a depth limiting spring is fitted over each fertilizer spray pipe. The outer wheel hub of the seed fertilizer wheel disc away from the mounting plate horizontally extends, the upper end of a bracket is fixed on the wheel disc shaft, a wheel disc side plate is fixed on the wheel disc shaft via a bearing, and the outer end of the wheel disc side plate is fixedly connected with the seed fertilizer wheel disc. A seed distributing port is formed at the lower end of the bracket, and a brush seed wheel is mounted close to the lower end of the bracket. A plurality of seed feeding ports located on the same circumference as the seed distributing port are evenly distributed on the seed fertilizer wheel disc, and a seed feeding duck bill is arranged at each seed feeding port, to accomplish dibbling of liquid fertilizer and seeds.

Description

technical field [0001] The invention relates to a wheel-type fertilizer planter, which belongs to the technical field of agricultural machinery. Background technique [0002] Liquid fertilizer applicators currently on the market or reported in the literature include hand-held fertilizing guns, crank-link mechanism-driven needle-type liquid fertilizer deep applicators, liquid fertilizer variable sprinklers, and the like. The hand-held fertilizer applicator is a manual operation with high labor intensity and low efficiency; the piercing needle type liquid fertilizer deep applicator driven by the crank-link mechanism adopts a piercing hole fertilization mechanism designed in the form of a crank rocker, and the fertilizer spraying needle is fixed on the connecting rod. In the process of work, vertical reciprocating motion is performed, and after being inserted into the soil, the control valve opens and the liquid fertilizer is sprayed out from the needle hole of the fertilizer s...

Problems solved by technology

[0003] In the case of mulching planting, the general fertilization method, whether it is granular fertilizer or liquid fertilizer, the fertilizer applied near the root of the crop will flow along the mulch film to a place far away from the crop after irrigation, and the fertilizer utilization rate is very low and the waste is serious , especially liquid fertilizer, if it is directly sprinkled on the mulch film, on the one hand, it will disperse, on the other hand, it will volatilize and decompose after being exposed to the sun, and the waste will be more serious
