Fertilizer applicator for crop seedlings

Abstract

The invention discloses a fertilizer applicator for crop seedlings. The fertilizer applicator comprises a rack, a lifting frame, a driving wheel landing gear, a drive system, a quantitative fertilizer applying device, a fixed-point fertilizer applicator assembly and the like, wherein the quantitative fertilizer applying device is designed as a quantification-adjustable movable square quantitative box; the fertilizer applicator assembly is a crank-slider mechanism, a hole shoveling pipe is driven by a fertilizer applying crank to move up and down and be inserted into the soil layer and a door opener is arranged at the same time to ensure that a door is timely opened and the fertilizer is applied into a specified depth of the soil layer; a ratchet mechanism is adopted on the connection of a driving wheel and a drive wheel axle to ensure that the reversing and the steering are flexible; the drive system adopts chain wheel chain drive and the fertilization plant spacing can be adjusted through adjusting the tooth number of the chain wheel; a square U-shaped bolt is arranged at the joint of the fixed-point fertilizer applicator assembly and the rack to fix; the rack is adjustable in length; one or more than one fertilizer applicator assembly can be arranged through adjusting the U-shaped bolt to ensure that one-row or multi-row fertilization is realized; the rack and a traction frame are arranged at the periphery of the fertilizer applicator body to ensure that the fertilizer applicator is suitable for mechanical traction such as tractors and the like.

Description

technical field [0001] The invention relates to a crop seedling fertilizing machine, in particular to a fixed-point, quantitative, and shovel-hole fertilizing machine for raising seedling fertilizers before and after transplanting crop seedlings (including tobacco seedlings) and seedling fertilizers for growing seedlings. Background technique [0002] At present, the crop seedling fertilizer applicators on the market are only furrow-type fertilization machines, most of which are inseparable from manual operation, and can only be fertilized before transplanting crop seedlings. The waste of fertilizer is large, the raising of crop seedlings is slow, and the work efficiency is low. After the crop seedlings are planted, there is no fertilization machine to fertilize, and only manpower is used to fertilize, which is labor-intensive, low in efficiency, and high in production costs. General wooden or metal fertilization machines cannot fertilize quantitatively, let alone freely adj...

AI Technical Summary

Problems solved by technology

[0002] At present, the crop seedling fertilizer applicators on the market are only plow-type fertilization machines, most of which cannot be separated from manual operation, and can only be fertilized before transplanting crop seedlings. The waste of fertilizer is large, the raising of crop seedlings is slow, and the work efficiency is low.

After the crop seedlings are planted, there is no fertilization machine to fertilize, and only manpower is used to fertilize, which is labor-intensive, low in efficiency, and high in production costs.

Ordinary wooden or metal fertilization machines cannot fertilize quantitatively, let alone freely adjust the plant spacing, row spacing and depth of fertilization

The utility model patent with the application number 201120088374.1, the application date is 2011.03.22, and the authorized announcement date is 2011.12.21 discloses a technical solution of a corn fertilizer spreader. Although this prior art also uses mechanical power fertilization, the invention The power of the gasoline engine is mainly used to drive the fertilization device. The forward and backward of the corn fertilizer applicator still needs to be pushed manually, like a trolley, it cannot be pulled by a tractor, and the working efficiency is relatively slow, and the fertilizer applicator has no shovel hole. Institutions such as pipes can only fertilize the surface soil, and cannot be applied deep into the soil layer, let alone multi-row fertilization of more than 2 rows
