Easy-to-maintain paddy side deep fertilizer applying and discharging device and fertilizing machine

Abstract

The invention discloses an easy-to-maintain paddy side deep fertilizer applying discharging device and a fertilizing machine. The fertilizer applying discharging device comprises an upper rack, a lower rack, an upper shell, a lower shell, a fertilizer cleaning brush, a drive gear, a driven gear, a grooved pulley shaft, a grooved pulley, a fertilizer box, a hexagonal shaft, a jaw clutch, a coupler and an electromotor, wherein the upper rack can upwards fold around a rotating point of the upper rack and the lower rack, so that the upper shell is opened, the grooved pulley and the fertilizer cleaning brush can be conveniently taken out from the upper part, and the fertilizer discharging device is cleaned. Two symmetrical lower shell bush seats are arranged at the left and the right of the rear part of the lower shell, and the usage of one lower shell bush seat can be determined according to an installation position of the jaw clutch of the fertilizing machine, so that the input of a lower shell mold is reduced.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an easy-to-maintain paddy side-deep fertilization and discharge device and a fertilizer applicator. Background technique [0002] The side-deep fertilization technology of rice can improve the utilization rate of chemical fertilizers and reduce environmental pollution. Fertilizers for paddy fields are different from fertilization machines for dry fields. When chemical fertilizers are applied to paddy fields, the environment in the paddy fields is humid, which can easily cause deliquescence of chemical fertilizers, blockage of fertilizer dischargers and fertilizer delivery pipes, and fertilization machines need to be cleaned every day. Therefore, rice fertilization machinery has been developing slow. At present, there are many problems in the side deep fertilization machine of rice, such as: the structure of the horizontal hole disc type is too complicated, the manufacturing cost is high...

AI Technical Summary

Problems solved by technology

Fertilizers for paddy fields are different from fertilization machines for dry fields. When chemical fertilizers are applied to paddy fields, the environment in the paddy fields is humid, which can easily cause deliquescence of chemical fertilizers, blockage of fertilizer dischargers and fertilizer delivery pipes, and fertilization machines need to be cleaned every day. Therefore, rice fertilization machinery has been developing slow

At present, there are many problems in the side deep fertilization machine of rice, such as: the structure of the horizontal hole disc type is too complicated, the manufacturing cost is high, and the maintenance is inconvenient; Bolt fixed connection, or fix the upper shell on the frame, only open the lower shell, take out the sheave for cleaning

In practice, it is very inconvenient to open the lower casing on a high-speed rice transplanter; some fertilizer spreaders directly use a hexagonal shaft to pass through the hollow shaft of the outer sheave to drive the outer sheave to rotate

When cleaning the outer grooved wheel, the grooved wheel cannot be taken out directly from the upper and lower casings, and the cleaning work is difficult

Seriously affected the promotion of side deep fertilization technology in rice production
