Annular spraying device

Abstract

The invention discloses an annular spraying device which comprises a base. Wheels are installed at the bottom of the base, a pesticide box used for containing pesticide is installed in the base, a stand column body is arranged on the base, an atomizer is connected to the stand column body in a sliding manner, and a lifting mechanism is arranged on the base. An annular atomizing head is installed on the atomizer, and a liquid pump and an electric control device used for controlling starting and stopping of the liquid pump are installed in the base. The liquid pump is connected with the atomizer through a liquid outlet pipe, and the atomizer is connected with the annular atomizing head through an aerosol output pipe. According to the annular atomizing device, pesticide can be fully released and utilized, the pesticide use efficiency is improved, possibility is provided for accurate quantitative operation, and small-area differential operation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production equipment, and in particular relates to an annular spraying device. Background technique [0002] Spraying is a common way of fertilizing and using pesticides in agricultural production. A liquid with a specific formula is atomized into a liquid aerosol, and then sprayed onto the surface of crops under the action of directional airflow to achieve the purpose of fertilization or medicine. Most of the existing spray devices are pneumatic fogging methods, which realize liquid atomization and directional transport of aerosol particles through high-pressure and high-speed air. The most common knapsack fogger uses a hand-held spray rod to realize the fertilization and spraying process. Both actual production and research have shown that the existing methods have the following problems: (1) The amount of atomization is related to gas pressure, and the propagation speed and distance of l...

AI Technical Summary

Problems solved by technology

Both actual production and research have shown that the existing methods have the following problems: (1) The amount of atomization is related to gas pressure, and the propagation speed and distance of liquid aerosol are also related to pressure. Large amount of mist, slow speed and short-distance drug administration cannot be realized ; (2) Since the aerosol of the liquid medicine spreads in a one-way similar to a conical form, it is easy to form a shielding effect during the operation, and crops are unevenly received by the medicine and fertilized; (3) The efficiency of the liquid medicine attachment is low, and a considerable proportion of the medicine The liquid drifts with the air or falls into the soil, which is not only wasteful, but also causes potential air and soil pollution; (4) Adjacent crops cannot achieve differentiated fertilization and medication
