Abstract

The utility model relates to a component of a liquid sprayer, which is composed of a spray head and a spray pipe which are connected with each other. The spray pipe is composed of at least two hollow sleeve pipes which are telescopic and are glidingly fitted with each other. A transfusion flexible pipe which is connected and fixed with the spray head is arranged in the sleeve pipes. The utility model not only can be used for spraying medicine for short-stalked crop, and the utility model is convenient for foliage dressing and disinsection for high-stalked crop.

Description

The scalable spray boom of sprayer

The utility model relates to a kind of parts of liquid dispenser.

The spray boom of existing liquid dispenser all is made up of jet pipe and shower nozzle, cartridge nozzle is at the front end of jet pipe, handle and switch generally are equipped with in the rear end of jet pipe, the diameter and the length of jet pipe are all fixed, and it is all shorter, therefore the medicine mist that sprays that is used for high strain fruit tree is felt inconvenience very much, if jet pipe is done longlyer, the spray medicine that then is used for short strain vegetables is dumb again.

Task of the present utility model is to design the telescopic novel spray boom of a kind of jet pipe length.

Task of the present utility model is finished like this: it comprises jet pipe and shower nozzle, and jet pipe is joined telescopic hollow sleeve by at least two joint cunnings and is socketed to form, and the rubber or the plastic infusion flexible pipe that are connected and fixed with shower nozzle are arranged in the sleeve pipe.

The infusion tube other end links to each other with the liquid outlet of sprayer infusion pump or the liquid outlet of air-pot, and the switch of spray boom can be arranged on the infusion port place of infusion pump or air-pot, rather than is arranged on the handle place of spray boom.

The cross section of jet pipe can be circle, as the telescopic antenna of radio or television set, also can be square or hexagon.

Because jet pipe of the present utility model is made up of mutual socket, telescopic more piece, thereby the spray boom that constitutes is changeable, both can be used for the spray medicine of short stalk crop, can be used for foliage dressing and the desinsection of long-stalked crop again.Owing to be set with infusion tube in the jet pipe, carry the soup or the solution that need spray by this flexible pipe, thereby can not produce leakage, need not to consider the sealed against leakage problem of socket jet pipe, only need with the liquid outlet place of flexible pipe and shower nozzle and sprayer to be connected densified good, just can on spray boom, not produce leakage.Flexible pipe can stretch out from the handle of spray boom rear end when the jet pipe retraction shortens spray boom, stretches out when longer at flexible pipe, can be with the flexible pipe rolling of stretching out on the external hook of sprayer housing or get final product in the tube storing box.

Describe with the embodiment accompanying drawing more below.

Fig. 1 is the structural representation of the spray boom of a kind of two joint sleeve pipe sockets of the utility model.

With reference to accompanying drawing, the front end of jet pipe 1 is connected to shower nozzle 2, jet pipe 1 is socketed to form by the telescopic hollow sleeve 3 and 4 of two joint sliding fits, sleeve pipe 4 is littler than sleeve pipe 3, sleeve pipe 4 is socketed in the sleeve pipe 3, the endoporus shape of cross section of sleeve pipe 3 matches with the gabarit shape of cross section of sleeve pipe 4, be circle, (also square or regular hexagon), the front end of sleeve pipe 3 has spacer pin 5, longitudinal spacing groove 6 is arranged on the sleeve pipe 4, and spacer pin 5 can only be along stopper slot 6 slippages, thereby can prevent that sleeve pipe 4 from pulling out from sleeve pipe 3 fully.Rubber infusion tube 7 is housed in the cavity of sleeve pipe 3 and sleeve pipe 4, and the front end of flexible pipe tightly is enclosed within on the mouth of pipe 8 of shower nozzle 2, and the shell of shower nozzle 2 is fixed on the front end of sleeve pipe 4 with screw 9, and the rear end of flexible pipe 7 can be received on the liquid outlet of sprayer after stretching out from sleeve pipe 3 rear ends.A handle 10 also can be loaded onto in the rear end of sleeve pipe 3, and sleeve pipe 3 is longer than sleeve pipe 4, and the length overall of flexible pipe 7 to two sleeve pipes is also long.Under the situation that 3 joint sleeve pipes are arranged, the length of flexible pipe is also longer than the length overall of 3 joint sleeve pipes.So that flexible pipe can enter in the sleeve pipe that all stretches out fully, and also have enough surpluses to lift high the use for spray boom.Sleeve pipe can be made with thin-wall steel tube, also available duroplasts injection mo(u)lding.

Claims

1, the scalable spray boom of sprayer, comprise jet pipe (1) and shower nozzle (2), it is characterized in that jet pipe (1) is joined telescopic hollow sleeve (3,4) by at least two joint cunnings and is socketed to form, and the rubber or the plastic infusion flexible pipe (7) that are connected and fixed with shower nozzle (2) are arranged in the sleeve pipe.
