Cover type multi-point sprinkler head

Abstract

The invention discloses a cover type multi-point sprinkle head which can relieve the liquid medicine spraying velocity and prevent liquid medicine from splashing to the outside. The cover type multi-point sprinkle head is characterized in that one end of the sprinkle head is connected with an anti-splashing cover (3) which reduces the outside splashing liquid medicine, and the other end of the sprinkle head is provided with a screwed joint (1) which is connected with a spray rod of a sprayer; and the lower end of the anti-splashing cover (3) is opened, and spray ports (2) are respectively formed on the top of an inner cavity and side part which is connected with the sprinkle head and are communicated with a medicine box through the spray rod of the sprayer. The spray ports for top spraying and multi-point side spraying are formed in the sprinkle head, so that the number of liquid medicine outlets is increased, uniform spraying can be realized, the liquid medicine spraying speed of each spray port is relieved, the liquid medicine splashing is reduced, and the liquid medicine is sprayed to a smoke rod in the whole anti-splashing cover at low velocity in a short time.

Description

technical field [0001] The invention relates to a spray head device of an agricultural sprayer, in particular to a cover type multi-point spray head. Background technique [0002] In the process of flue-cured tobacco production, in order to make the tobacco leaves grow robustly and have better technological properties, according to the growth of the tobacco plants in the field, capping and pruning are carried out at the budding or flowering stage to eliminate the growth of terminal buds and axillary buds, so that nutrients can be concentrated Supply the leaves; after the terminal buds are removed, a large number of axillary buds will germinate and grow, and it is labor-intensive and time-consuming to remove the axillary buds by hand. In production practice, the current method is: after capping, use the chemical drug "Zhibusu" to manually smear the axillary bud position or use a beverage bottle to pour the medicinal liquid from the top of the tobacco plant. The effect of man...

AI Technical Summary

Problems solved by technology

The effect of manual application is good, but it is labor-intensive and time-consuming to apply to all the axillary buds. It is labor-intensive and increases the production cost; use a beverage bottle to pour the liquid medicine from the top of the tobacco plant, and a bottle of liquid medicine is only a few hundred milliliters. It is too time-consuming to bottle or pour medicine into the bottle. When spraying the medicine, the medicine liquid will be sprinkled on the tobacco leaves, which will have a certain adverse effect on the growth of the tobacco leaves and easily form pesticide residues.

[0003] Existing various nozzles, especially the nozzles of agricultural sprayers, produce the effect of spraying to the surroundings, and the coverage of the droplets is large, which is not suitable for the application of pesticides in tobacco planting or other agricultural production and planting.
