Description

Design method of sprayer and dual-mode sprayer structure

Technical Field

The application relates to instruments and meters special for agriculture, forestry, animal husbandry and fishing, in particular to a design method of a sprayer and a dual-mode sprayer structure.

Background

A nebulizer is a device that uses suction to spray a medicinal liquid or other liquid into a mist and uniformly spray the liquid onto other objects. The sprayer is widely applied to spraying operations in the aspects of preventing and controlling various crop diseases, insect pests and grass pests, preventing and controlling forestry and garden diseases and insect pests, preventing and controlling sanitation and epidemic diseases and the like.

The history of the sprayer is very long, and the main use of the sprayer in agricultural production is a backpack type manual sprayer, which has various types and different structures, but can be classified into two main types according to the working principle. The air pump type manual sprayer generally comprises a liquid medicine barrel, an air pump, a spray head and the like, and the structure of the air pump type manual sprayer is shown in fig. 11. The air pump type manual sprayer is different from the liquid pump type manual sprayer in that the liquid medicine is not directly pressurized, but air is pressed into the upper part of the airtight medicine barrel by a pump (the liquid medicine is only added to a water line, a part of space is reserved for storing pressure air), the liquid level is pressurized by the air, and then the liquid medicine is sprayed out through a spray head.

There are a number of technical problems that may be faced by such spray devices in general, with the series of problems that are most pronounced with the need for a sprayer to be filled with a variety of liquids.

In 1996, still-gani-bush et al invented a hand-held spray delivery system (patent application number CN 96194477.3) for dispensing a relatively viscous and/or solid-loaded liquid.

Li Guoxiang and the like explore and research a spraying system of a double-liquid-medicine double-pipeline sprayer, which comprises a reflux stirring system, a liquid medicine loop control system and a spraying system, adopts a hanging spray boom structure, improves the anti-floating performance of the sprayer, and can spray liquid medicines with different concentrations on the upper part, the middle and lower part of cotton plants under the condition that the total application amount is unchanged ("3 WP-1350 double-liquid-pipeline sprayer spraying system design", li Guoxiang and the like, xinjiang agricultural machinery, 2014, 6 th period).

The cleaning device and brush for sprayers and the corresponding cleaning method (grant publication number CN 103328112B) of m·claina et al provide a solution to the problems of clogging or contamination of paint residues in car cleaning.

The vaccine nebuliser of the application of F-kaz et al (grant bulletin number CN 101247845B) of the world health organization provides a method of selecting or optimising a nebuliser device to be used for delivering a vaccine so that rapid identification of a nebuliser suitable for testing as a vaccine nebuliser can be carried out by easily verifiable criteria.

It follows that in practice the liquid to be filled into the sprayer is not limited to pesticides or liquid fertilizers, but may include industrial cleaners, disinfectants, lacquers and even vaccines. Even if only in agricultural production, one sprayer is likely to be sprayed by filling liquid fertilizer, and also is likely to be filled with various liquid pesticides, and the problems of blockage, difficulty in cleaning, cross contamination risk and the like can exist when different liquid pesticides are repeatedly filled for a long time. In a narrower sense, there may be several different varieties of flowers or fruit trees in a private garden, where owners of the garden need to spray liquid fertilizers such as monopotassium phosphate, etc., pesticides such as imidacloprid, etc., bactericides such as kresoxim-methyl, etc., and even some special flowers such as hydrangea need to spray blue-adjusting agents such as ferrous sulfite, aluminum sulfate, etc. In the case of only one sprayer at home, only one sprayer can be sprayed, then cleaned again and the other sprayer can be filled again for spraying, so that not only is the work increased, but also new pollution to water or soil is easily caused by pouring of unused liquid medicine. The problem of increased work or secondary pollution is more prominent from the whole agricultural production.

For this reason, it is possible to solve the series of technical problems by developing a sprayer capable of freely switching among various spraying modes.
