Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a flow rate adjustable nozzle. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry. The science that studies agriculture is agronomy. The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is a basic industry that provides support for national economic construction and development, and agricultural irrigation is an indispensable part of agriculture.

[0003] The patent with publication number CN 217546895 U discloses an adjustable liquid flow nozzle for crop irrigation, which includes a pipe body and a nozzle; the pipe body is used to support internal components, the nozzle is installed on the pipe body, and a flow regulating component and a pipe connecting component are provided on the pipe body. The device adjusts the water spraying amount of the nozzle through the water flow after the baffle moves outward. Through the flow control spraying component, a plurality of water spray holes can be used to replace the pipeline for direct spraying, which can achieve the effect of slowing down the water flow and make the irrigation and sprinkling process more uniform. However, the device has the problem that the water pipe is connected to the connecting sleeve, and then the distance between the baffles in the relative baffle groove is adjusted by using structures such as a driver and a threaded column to adjust the flow size of the nozzle. However, each time the flow size is adjusted, the driver needs to be turned on, and a series of structures such as a threaded column, a telescopic column, and a rotating bearing are used to cooperate in adjusting the flow. The structure is complicated, which makes it difficult to arbitrarily and quickly control the flow size of the nozzle according to the needs of the operator to perform spraying or irrigation operations. Therefore, an adjustable flow nozzle is proposed to solve the problem that the existing nozzle is difficult to quickly adjust the flow size according to needs. Utility Model Content
