Paddy-field fertilizer once applying device

Abstract

The invention discloses a paddy-field fertilizer once applying device. The paddy-field fertilizer once applying device comprises a rotary cultivator. The front end of the rotary cultivator is connected with a tractor through a universal joint assembly, a side plate I is installed on one side of the rotary cultivator, a side plate II is installed on the other side of the rotary cultivator, a fertilizer box is fixed to the upper ends of the two side plates, the rear end of the rotary cultivator is connected with a land wheel through an installing plate, a chain wheel is arranged on the land wheel and is in chain transmission with a duplex chain wheel installed on the side plate I, power is transmitted to a fertilizer box chain wheel upwards by the duplex chain wheel, a fertilizer discharging shaft is driven by the fertilizer box chain wheel to rotate and is evenly provided with a plurality of outer groove wheels wrapped with fertilizer applying boxes respectively, the fertilizer applying boxes are communicated with the fertilizer box, fertilizer conveying pipes communicated with the fertilizer applying boxes are arranged at the bottoms of the fertilizer applying boxes, and the other ends of the fertilizer conveying pipes are communicated with a fertilizer device.

Description

[0001] technical field [0002] The invention relates to a one-time fertilization device for paddy fields, in particular to a fertilization device capable of synchronously completing full-width uniform fertilization, rotary tillage and raking operations. Background technique [0003] At present, there are many ways of fertilizing paddy fields in my country, including liquid spraying, ditch application and soil burial, and artificial solid scattering. The fertilization method that is used more in paddy fields is: before the paddy field soil rotary tillage and seeding operations, the fertilizer is sprinkled on the surface of the paddy field soil by hand, and then the single-function fertilizer with only the rotary blade assembly is used. A rotary tiller performs soil preparation, mixing fertilizer into the soil. Obviously, the above-mentioned fertilization method not only has low operation efficiency and high labor intensity, but also it is difficult to control the unifor...

AI Technical Summary

Problems solved by technology

Obviously, the above method of fertilization not only has low operation efficiency and high labor intensity, but also it is difficult to control the uniformity of artificial fertilization. After rotary tillage, the fertilizer content in the soil is uneven, and the operation quality is poor.

Surface application of chemical fertilizers, fertilizers volatilize in the air and are lost with water, which does not achieve the expected fertilization effect and pollutes air and water sources
