Spraying pipe device of agricultural spraying machine

Abstract

The invention discloses a spraying pipe device of an agricultural spraying machine. The spraying pipe device comprises an elbow, a hose, a straight pipe, a bent pipe and a spraying pipe, wherein hose clamps are arranged at the two ends of the hose; the hose is connected with the bent pipe and the straight pipe respectively through the hose clamps; the straight pipe, the bent pipe and the spraying pipe are connected by threads in sequence; a powder discharging hole rubber plug is arranged on the elbow; the spraying pipe is provided with a pressing cover and an infusion pipe; the infusion pipe is communicated with the spraying pipe through the pressing cover; a handle is arranged in the middle of the infusion pipe; the handle is fixedly connected with the straight pipe; a water inlet plug is arranged at one end of the infusion pipe; the water inlet plug is connected with the infusion pipe by gluing; a nozzle is arranged at the front end of the spraying pipe; the nozzle is in seamless connection with the spraying pipe; the nozzle is a spoiler type nozzle. The spraying pipe device of the agricultural spraying machine has a stable structure and good spraying effect, is convenient to mount, can be used for conveying air, dust flow and medicine liquid, and has no leakage.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to an agricultural sprayer nozzle device. Background technique [0002] As early as the mid-1960s, a small number of plant protection machinery manufacturers in my country began to develop and produce my country's first generation of backpack machines - WFB--18AC-type backpack machines by referring to Japanese prototypes. By the end of the 1970s, there were three or four backpack machines in China. Production plants, each developing backpack products. The national annual production and sales have been maintained at tens of thousands of units. After entering the 1990s, with the support of national policies, the first peak year of demand for backpack machines appeared in 1991-1992, and the number of manufacturers rapidly increased from five or six to more than 10. , the later developed enterprises are mainly township collective enterprises, and the products ar...
