Description

A kind of Novel backpack sprayer

Technical field

The present invention relates to a kind of spray apparatus, especially a kind of Novel backpack sprayer.

Background technology

With the continuous research and development and introduction of novel pesticide, application of the agricultural chemicals in agricultural production is more and more extensive.Particularly with The national foundation to agricultural product Pesticides limit standard and perfect, rationally, safety, accurate applying pesticides also increasingly become pass Key.Present pesticide sprayer is varied.Hand sprayer, the amount of labour is big, work rate is not high, does not apply to large area and makees Industry, and hand sprayer decoction has race, emits, leaks, dripping etc. and easily got wet with phenomenon, operating personnel by decoction, be easily poisoned Not environmentally；Motor driven sprayer is from great, noise is big, pollution is big, machine manual task environment is poor, and use cost is high；Electrodynamic type The electricity of sprayer storage battery determines the length of activity duration, and maintenance is difficult.And there is pressure in existing pesticide sprayer It is unstable, cause droplet size uneven, spray amount is not easy to control, causes and does not reach expected effect of spraying pesticide.It is also various Sprayer is all single spraying head, or a little many shower nozzles；The size of its spraying swath is the amplitude of user arms swing, and application dosage is then It is the forward speed of user.Therefore, it, which applies quality, very big randomness, depends entirely on the experience of user.Its Cause prevention effect poor or as a result dispenser is uneven, otherwise in order to pursue the excessive applying pesticides of prevention effect, cause agricultural product Pesticides limitation is exceeded.

The content of the invention

Present invention aims at there is provided a kind of high-precision and light cheap Novel backpack in view of the shortcomings of the prior art Sprayer, its pressure energy adjusts output pressure using liquid nitrogen or liquid carbon dioxide as power by stable-pressure device, can be fine Adjustment droplet size distribution；Spray boom uses many shower nozzle transversaries, the size of spraying swath be shower nozzle quantity number, example Such as：Spray boom can make two shower nozzles, one meter of spraying swath, three 1.5 meters of shower nozzle spraying swaths, or 6 shower nozzles, 3 meters of spraying swaths, rather than arms swing width Degree；Containing vessel uses Coke bottle, a kind of container cheap and easy to get, it is adaptable to the use in the vegetable plot or greenhouse of small area.This hair It is bright to be specially adapted to agri-scientific research worker progress field demonstration or the use for the pesticide-treated for doing field test cell.

A kind of Novel backpack sprayer of the present invention, including gas cylinder, regulator, Coke bottle connection dress Put, safety valve, nozzle, spray boom, bat-handle switch, connecting tube, Coke bottle, hand lever, brace；It is characterized in that having on the gas cylinder Brace, and gas cylinder is connected to the regulator for air pressure in Coke bottle；The Coke bottle attachment means are connected by connecting tube Connect and be connected outside regulator, Coke bottle attachment means with connecting tube, be internally provided with the siphunculus of a straight cutting Coke bottle bottom, There is the internal thread and O-ring seal being engaged with the bottleneck of Coke bottle in the block of Coke bottle attachment means, and pass through Coke bottle The screw thread of bottleneck is closely threaded together, and side, which is connected with, in the block of Coke bottle attachment means prevents that air pressure exceedes peace in Coke bottle Total head and the safety valve of pressure release, opposite side are connected by conduit with the connecting tube of gas cylinder；The end of the hand lever passes through Connecting tube connects the block upper end of Coke bottle attachment means, there is bat-handle switch on hand lever；The top connection spray boom of hand lever, in spray Multiple nozzles are equidistantly installed on bar.

The beneficial effects of the utility model are to devise a kind of Novel backpack sprayer, the appearance of the powder charge liquid of the device Device is Coke bottle, with low cost, and can independently allocate regulator to control according to the height, density, thickness of Different Crop The number of spray amount processed.Cola bottle cap is first turned on, liquid medicine is added into Coke bottle, Coke bottle is twisted with Coke bottle coupling arrangement Tightly, then backpack type high-pressure gas cylinder is carried on the back in the back of staff by brace, one is held bar of stopping, and a hand is held can Happy bottle coupling arrangement, opens gas cylinder knob, depresses bat-handle switch, and by regulator control pressure, medicament is passed through into spray Head is sprayed out.The utility model clever structure, it is reasonable in design, it is easy to use, can be according to actual conditions adjustable spraying amount How much, with very big promotional value.

Brief description of the drawings

Fig. 1 is overall structure diagram of the present utility model.

Fig. 2 is the structural representation of the utility model Coke bottle part.

In figure, gas cylinder 1, regulator 2, Coke bottle attachment means 3, safety valve 4, nozzle 5, spray boom 6, bat-handle switch 7th, connecting tube 8, Coke bottle 9, hand lever 10, brace 11.

Embodiment

It is better embodiment of the present utility model below, but does not therefore limit protection domain of the present utility model.

As illustrated, a kind of Novel backpack sprayer, including gas cylinder 1, regulator 2, Coke bottle attachment means 3rd, safety valve 4, nozzle 5, spray boom 6, bat-handle switch 7, connecting tube 8, Coke bottle 9, hand lever 10, brace 11；It is characterized in that the height There is brace 11 on air bottle 1, and gas cylinder 1 is connected to the regulator 2 for air pressure in Coke bottle 9；The Coke bottle connection Device 3 connects regulator 2 by connecting tube 8, and the outside of Coke bottle attachment means 3 is connected with connecting tube 8, is internally provided with one There is the interior spiral shell being engaged with the bottleneck of Coke bottle 9 in the siphunculus of the bottom of straight cutting Coke bottle 9, the block of Coke bottle attachment means 3 Line, and being closely threaded together by the screw thread of Coke bottle bottleneck, side is connected with that prevent can in the block of Coke bottle attachment means 3 Air pressure exceedes the safety valve 4 of safety value and pressure release in happy bottle 9, and opposite side is connected by conduit with the connecting tube 8 of gas cylinder 1 Connect；The end of the hand lever 10 connects the block upper end of Coke bottle attachment means 3 by connecting tube 8, has handle on hand lever 10 Switch 7；The top connection spray boom 6 of hand lever 10, is equidistantly installed with multiple nozzles 5 on spray boom 6.

The utility model devises a kind of Novel backpack sprayer, and the container of the powder charge liquid of the device is Coke bottle, into This is cheap, and can independently allocate regulator to control many of spray amount according to the height, density, thickness of Different Crop It is few.Cola bottle cap is first turned on, liquid medicine is added into Coke bottle 9, Coke bottle 9 is tightened with Coke bottle coupling arrangement 3, then passed through Brace 11 carries on the back backpack type high-pressure gas cylinder in the back of staff, and one is held bar 10 of stopping, and a hand holds Coke bottle connection Connection device 3, opens the knob of gas cylinder 1, depresses bat-handle switch 7, by the control pressure of regulator 2, medicament is passed through into shower nozzle 5 Spray out.The utility model clever structure, it is reasonable in design, it is easy to use, can be according to many of actual conditions adjustable spraying amount It is few, with very big promotional value.
