Spraying device with adjustable connecting rod

Abstract

The invention relates to the technical field of spraying devices and particularly relates to a spraying device with an adjustable connecting rod. The spraying device comprises a shell body and a sealing ring, wherein the inner side of the right end of the shell body is fixedly connected with the outer side of the sealing ring, the inner side of the sealing ring is rotatably connected with a rotarycolumn which is horizontally arranged, a piston plate is arranged at the outer side of the rotary column, the right end of the sealing ring is rotatably connected with a rotating plate which is arranged vertically, and the top end of the rotating plate is fixedly connected with a connecting rod which is arranged vertically. According to the spraying device with the adjustable connecting rod, a hand grip position on the connecting rod can be adjusted through an arranged spring, a rubber block and a piston, free adjustment can be performed according to difference of arm lengths and force applying habits of all practitioners, occupational disease symptoms such as arthritis and scapulohumeral periarthritis caused by long-term manual work are avoided and reduced, and thus, health of work of the practitioners is facilitated; and this design is novel in conception and is scientific, so that the spraying device has huge safety benefits and extensive market prospects and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of spray devices, in particular to a spray device with an adjustable connecting rod. Background technique [0002] Sprayer is the abbreviation of spray device. Sprayer is a device that uses air suction to turn liquid medicine or other liquids into mist and sprays them evenly on other objects. It is composed of compressed air devices, thin tubes, nozzles, etc. In rural areas, sprayers It is an indispensable and important agricultural tool for the prevention and control of diseases and insect pests. According to the spraying principle of the sprayer, it can be divided into four types: Bernoulli principle, high-speed water impact principle, centrifugal force principle, and ultrasonic atomization principle. Therefore, there is an increasing demand for a spray device with an adjustable connecting rod. increase. [0003] Most of the spray device handles currently on the market are fixed on the connecting rod, and...

AI Technical Summary

Problems solved by technology

[0003] Most of the spray device handles currently on the market are fixed on the connecting rod, and each practitioner has different arm lengths and exertion habits. Long-term labor will cause occupational diseases such as arthritis and frozen shoulder, which is not conducive to the practitioners. The work is healthy, and the traditional spray device lacks the return function of the infusion tube. Carrying the spray device under the condition of poor seal of the nozzle will cause the leakage of the infusion tube, and the leakage of pesticide will corrode the human body and seriously threaten the life and health of practitioners. Therefore, in view of the above problems Propose a spray device with adjustable connecting rod
