Description
The utility model relates to the nipple of agricultural medical instruments, a kind of more precisely special joint of knapsack sprayer air chamber.
At present, the air chamber on the sprayer of agricultural band air chamber itself is threaded joint, so that connect with sprayer, but air chamber as one of critical piece on the sprayer, reasons such as, the strength of materials low because of working pressure and ageing resistace difference make air chamber become consumable accessory, and peasant brother buys back new sprayer and uses not long-time, air chamber promptly damages, and cause sprayer to be scrapped, even if it is there is fittings supply in market, also with low quality because of it, the cost height brings great inconvenience to the user.
The purpose of this utility model provides a kind of knapsack sprayer air chamber special joint, so that will use the refill-unit of the empty pesticide bottle of agricultural chemicals as the sprayer air chamber, connect with sprayer easily, to solve perishable and the contradiction that the accessory life-span is low of former air chamber, for the user brings convenience.
The purpose of this utility model is achieved in that a kind of knapsack sprayer air chamber special joint, be hollow, the one end has screw thread (1), the tail end of screw thread (1) is provided with sealing device (2,3), there is screw thread (4) front portion of the joint other end, the tail end of screw thread (4) radially has through hole (5), in the side of this through hole (5) valve pin (6) inwardly is housed radially; The stage casing at rear portion radially has through hole (7); The tail end at rear portion is provided with sealing ring (8).
The utility model has following advantage:
1, simple in structure, easy to manufacture.
2, twice laid, minimizing are polluted.The utility model designs at utilizing discarded pesticide bottle, the processing of national toxic pesticide bottle is at present mostly adopted buried or is abandoned in the river, all pollute equally, part metals bottle particularly, as Packaging Bottle (aluminum) of " killing chrysanthemum fat " etc., the someone collects sales of goods such as skillet, spoon, directly influences people's health, utilize the utility model to mix the sky pesticide bottle and useless pesticide bottle is turned waste into wealth, can reduce environmental pollution again as the air chamber of sprayer.
3, improve performance, expansion purposes, practical.Because of existing pesticides packaging bottle as (systems of moulding) such as " killing chrysanthemum fat " (aluminum), " nuvacron ", " one examination spirit ", all big, the withstand voltage height of the intensity than the air chamber that uses on the present sprayer, life-span are long, so utilize the utility model to cooperate discarded pesticide bottle can improve the performance of former air chamber, big because of bearing pressure, can improve atomization quality, increase projected area and height, can directly medicine be sprayed, be convenient to the small size orchard and substitute as 3-4 meters high fruit trees.
4, easy to use.The air chamber of the sprayer that the peasant uses is in case damage, and utilizes the utility model to mix at one's side discarded medicine bottle, and sprayer is normally used.
