Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0014] see figure 1 , an agricultural sprayer injection device includes a telescopic nozzle 1 and a connecting part 2.

[0015] The telescopic nozzle 1 is sealed and connected with the connecting part 2. It is the core part of the device, and it can be adjusted telescopically. The user can adjust the telescopic nozzle 1 to achieve a satisfactory distance. Fertilize.

[0016] In order to ensure that the device can be implemented normally, the inside of the telescopic nozzle 1 is hollow.

[0017] The telescopic nozzle 1 adopted by the device includes several nozzles 1a with different calibers, and these nozzles 1a are sequentially connected by matching the outer diameter of the nozzle 1a and the inner diameter of the connected nozzle 1a.

Abstract

The invention discloses a spraying device of an agricultural sprayer. The device comprises a telescopic spraying pipe and a connecting part, wherein the telescopic spraying pipe is hollow; the telescopic spraying pipe is connected with the connecting part in a sealed way; the telescopic spraying pipe comprises a plurality of spraying pipes with different apertures; the spraying pipes are connected with each other in sequence in a sealed way according to matched internal diameters of the spraying pipes; sealing and fixing devices are arranged at the connecting parts of pipe openings of the spraying pipes respectively; and a nozzle is also arranged at the top end of the telescopic spraying pipe. The spraying device can be expanded and retracted according to needs of users, is very convenient to use, and is convenient to carry. The spraying device is applicable to various agricultural sprayers; moreover, the sprayer does not need to be integrally replaced during replacing, so that the cost is greatly reduced.

Description

technical field [0001] The invention relates to a sprayer device, in particular to an agricultural sprayer injection device. Background technique [0002] China is a famous agricultural country, so the number of farmers accounts for a considerable part of the country's population. Many farmers have many different choices for pesticide sprayers. [0003] At present, there are various agricultural sprayers on the market, such as: ordinary hand-operated sprayers, which are suitable for small amounts of fertilization, but the cost is very low; high-pressure automatic sprayers, whose efficiency is higher than that of ordinary hand-operated sprayers Three to four times; electric sprayer, which not only improves the efficiency, but also saves the user's physical strength; motorized sprayer, which is the most advanced agricultural sprayer at present, is suitable for large-scale farmland fertilization, and the efficiency is very high, but the cost very high. [0004] However, when ...
