Air force fertilizing device

Abstract

The invention relates to a fertilizing tool, in particular to an air force fertilizing device. The air force fertilizing device comprises an air pump, a material bin, a mixing conveying device and a fertilizing spraying head. The mixing conveying device is composed of an air force spraying head and a mixed material spraying pipe. The air force spraying head extends into the mixed material spraying pipe from the rear end, the rear end of the air force spraying head is provided with a compressed air input connector, the back of the mixed material spraying pipe is provided with a feeding connector, the front inner space of the mixed material spraying pipe forms a pressurizing conveying cavity, and the front end of the pressurizing conveying cavity is provided with a straight-through discharging connector. An exhaust port of the air pump is connected to the compressed air input connector of the air force spraying head, a conveying outlet of the material bin is connected to the feeding connector of the mixing conveying device, and the discharging connector of the mixing conveying device is connected to a mixed gas input connector of the fertilizing spraying head (1). Air force of compressed air is used for fertilizing or pesticide spraying, so that the device needs no mechanical movement mechanism; the air and fertilizer or pesticides are fully mixed, so that even and efficient fertilizing is achieved. The air force fertilizing device is suitable for spraying liquid fertilizer or liquid pesticides and also suitable for spreading solid granulated fertilizer.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a fertilizing implement. Background technique [0002] Fertilizer is a kind of substance that provides essential nutrients for crops, improves soil properties, and improves soil fertility. When the soil cannot provide the nutrients needed for crop growth, fertilization must be carried out. [0003] Existing fertilizer spreaders are driven by the power output shaft to rotate the fertilizer spreader to spread the fertilizer by centrifugal force. There are two types of single disc and double disc, which have the disadvantages of complex structure and uneven fertilization. The fertilizer machine can only spread the fertilizer of solid particles, and does not have the function of spraying liquid fertilizer. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the existing fertilizing equipment and provide a pneumatic fertilizing device...
