Agricultural automatic tumbril

Abstract

The invention belongs to the field of agricultural automation, and particularly relates to an agricultural automatic tumbril. The tumbril comprises a storage shell A, a storage shell B, a distributing plate, a transfer mechanism and a centrifuging mechanism, wherein the two branch ends of an n-shaped plate are matched with a shaft A bearing with wheels at the two ends, and the hopper-shaped storage shell A is installed at the upper end of the n-shaped plate; according to the operation speed of the tumbril, the discharging amount within the unit time can be automatically adjusted; the centrifuging mechanism can drive the distributing plate to move by difference distances according to changes of the motion speed of the tumbril, and therefor the size of a discharging outlet in the tumbril can be changed, then, the discharging amount of granular fertilizer within the unit time can be changed according to the operation speed of the tumbril, the thickness of fertilizer falling into soil can be kept identical basically, and fertilizer waste is avoided while the normal growth requirement amount of plants is met.

Description

technical field [0001] The invention belongs to the field of agricultural automation, in particular to an agricultural automatic fertilizing vehicle. Background technique [0002] With the development of agricultural technology, in order to improve the efficiency of agricultural labor, various agricultural machinery have emerged, among which automatic fertilization vehicles are one of them; during the operation of traditional automatic fertilization vehicles, the size of the fertilization outlet is fixed, and the unit time The amount of fertilizer sprinkled from the fertilization truck is constant; according to the running speed of the fertilizer truck, the fertilizer falling on the soil along the direction of the fertilizer truck is uneven; if the speed of the fertilizer truck is faster, the distance it moves per unit time is longer ; Since the amount of fertilizer sprinkled per unit time is constant, the fertilizer falling into the soil within this distance is relatively t...

Problems solved by technology

[0002] With the development of agricultural technology, in order to improve the efficiency of agricultural labor, various agricultural machinery have emerged, among which automatic fertilization vehicles are one of them; during the operation of traditional automatic fertilization vehicles, the size of the fertilization outlet is fixed, and the unit time The amount of fertilizer sprinkled from the fertilization truck is constant; according to the running speed of the fertilizer truck, the fertilizer falling on the soil along the direction of the fertilizer truck is uneven; if the speed of the fertilizer truck is faster, the distance it moves per unit time is longer ; Since the amount of fertilizer sprinkled per unit time is constant, the fertilizer falling into the soil within this distance is relatively thin, resulting in insufficient fertilizer application within the corresponding running distance and affecting the normal growth of plants; if the speed of the fertilizer application vehicle is slower , the shorter the movement distance per unit time; since the amount of fertilizer sprinkled per unit time is constant, the fertilizer falling into the soil within this distance is thicker, resulting in too much fertilizer application within this distance. Waste of fertilizer; the constant fertilizer output per unit time of traditional fertilization trucks will cause uneven fertilization due to changes in the speed of fertilizer trucks, which will affect the growth of plants or waste fertilizers; the outlet of traditional fertilizer trucks is often covered by wet particles. Fertilizer blockage, repeated dredging of the blocked discharge port will seriously reduce the efficiency of fertilization; in addition, the traditional fertilization truck is a waste of physical strength of the workers, and it is a waste of physical strength to push the fertilizer truck for a long time, resulting in the subsequent stage of fertilization. The fertilization truck is more laborious; after a long period of physical exertion, when the fertilizer truck encounters a deep pit, it is more laborious to push the fertilizer truck out of the pit
