Abstract
The utility model discloses a backpack type manual strong sprayer. A pressure air pipe from an air chamber is positioned on a nozzle, the pressure air pipe is communicated with a vortex chamber of the nozzle, a one-way air exhaust valve is positioned on the pressure air pipe, the one-way air exhaust valve is directly installed on the nozzle preferably, an air amount adjusting valve is arranged on the pressure air pipe, the air amount adjusting valve is installed close to a handle switch preferably, and a plurality of clamps are arranged between the pressure air pipe and a rubber pipe and between the pressure air pipe and a spraying rod. The backpack type manual strong sprayer effectively solves the problems that an existing backpack type manual sprayer is larger in fogdrop to cause a lot of pesticide to flow or scatter, low in pesticide utilization rate and serious in environmental pollution. The backpack type manual strong sprayer avoids damage accidents, caused by air chamber overload, to the human body.
Description
Technical field
The utility model relates to agricultural equipment, particularly the manual powerful sprayer of a kind of backpack.
Background technology
Knapsack hand sprayer is the present output maximum of China, most popular a kind of agroatomizer.Formed by pump, air chamber, rocking handle, ladle body, connecting rod, sebific duct, spray boom, braces, nozzle, spray boom switch and soup mouth.Born by the operator, by shaking of rocking handle, leather cup samsara in pump is opened and closed, internal pressure raises gradually in the air chamber thereby make, and the soup of ladle body bottom is through sebific duct, spray boom, at last by nozzle ejection mist.This spray structure compactness, low price, simple to operate, the basic spraying needs that satisfy Different Crop.
Yet this sprayer rests on big droplet spray technique level for a long time, and the agricultural chemicals of sprinkling only has small part to be attached to plant hat surface, and most soups all trickle or are scattering on the ground, and the agricultural chemicals availability is low, and environmental pollution is serious.When in case misoperation causes the air chamber overload, the injury accident to human body may take place also.
The utility model content
Problem to be solved in the utility model is the deficiencies in the prior art parts, the soup that is the ladle body bottom can only be finished spraying through sebific duct, spray boom to nozzle by the internal pressure in the air chamber, the manual powerful sprayer of a kind of backpack is proposed, a pressure air pipe is installed between nozzle and air chamber, be equipped with corresponding one-way exhaust valve, volume damper and clamp, just can improve atomizing effect to minor air cell's air of directly exerting pressure.
The utility model is by realizing by the following technical solutions:
Manufacture and design the manual powerful sprayer of backpack, comprising: nozzle is provided with the pressure air pipe from air chamber; The pressure air pipe communicates with the minor air cell of nozzle; The pressure air pipe is provided with one-way exhaust valve; One-way exhaust valve preferably is directly installed on the nozzle; The pressure air pipe is provided with volume damper; Volume damper preferably is installed near near the spray boom switch; Be provided with a plurality of clamps between pressure air pipe and sebific duct, the spray boom.
The utility model is owing to install a pressure air pipe between nozzle and air chamber, and communicate with the minor air cell of nozzle, be equipped with corresponding one-way exhaust valve, volume damper and clamp, just can utilize and a part of pressure air of air chamber is applied directly on the soup of minor air cell, make the droplet of ejection become littler.
The manual powerful sprayer of this backpack compared with the prior art, because the resistance that the resistance ratios soup that pressure air runs in the pressure air pipe runs in sebific duct and spray boom is little, the pressure air that feeds in addition in the minor air cell can make droplet become littler, thereby mist droplet deposition efficient is higher, reduce the trickling of droplet or be scattered, the agricultural chemicals availability further improves, and is conducive to reduce environmental pollution, avoids causing injury accident to human body because of air chamber overload; One-way exhaust valve can be guaranteed from the unidirectional minor air cell that sprays on the nozzle of the pressure air of air chamber; Can regulate the pressure air flow at any time easily according to the spraying needs by volume damper, a plurality of clamps then are used for the fixing of pressure air pipe.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation according to a kind of concrete structure that the utility model proposes; Fig. 2 is the partial structurtes schematic diagram according to a kind of concrete structure that the utility model proposes.
(1) is pump among the figure, and (2) are air chamber, and (3) are rocking handle, (4) be ladle body, (5) are connecting rod, and (6) are sebific duct, (7) be spray boom, (8) are braces, and (9) are nozzle, (10) be the spray boom switch, (11) are the soup mouth, and (12) are the pressure air pipe, (13) be the minor air cell, (14) be one-way exhaust valve, (15) are volume damper, and (16) are clamp.
Embodiment
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
Fig. 1 is structural representation of the present utility model, and Fig. 2 is partial structurtes schematic diagram of the present utility model.
by pump (1), air chamber (2), rocking handle (3), ladle body (4), connecting rod (5), sebific duct (6), spray boom (7), braces (8), nozzle (9), the back carried hand strong sprayer that spray boom switch (10) and liquid mouth (11) form, nozzle (9) is provided with a pressure air pipe from air chamber (2) (12), pressure air pipe (12) communicates with the minor air cell (13) of nozzle (9), pressure air pipe (12) is provided with an one-way exhaust valve (14), one-way exhaust valve (14) is directly installed on nozzle (9), pressure air pipe (12) is provided with a volume damper (15), volume damper (15) is arranged near near spray boom switch (10), pressure air pipe (12) and sebific duct (6), be provided with 5 clamps (16) between spray boom (7).
During use, operating process is identical with knapsack hand sprayer, open the soup spray boom switch on the spray boom after, open volume damper, just can begin to carry out brute force spraying.According to droplet size and deposition, drift situation, regulate air quantity at any time.
The manual powerful sprayer of backpack has solved effectively that existing knapsack hand sprayer droplet is bigger than normal to be caused a large amount of tricklings or be scattered, cause the problem that the agricultural chemicals availability is not high and environmental pollution is serious, avoids causing injury accident to human body because of the air chamber overload.
