Abstract
The utility model discloses a back-pack type sprayer with automatic suction and mixing which is suitable for farm crops and is particularly suitable for paddy rice immunization disinsection. The back-pack type sprayer with the automatic suction and mixing comprises a rocker rod, a connecting rod, a pump, a mixed liquid container, a water suction device, a spray head, etc. The sprayer is provided with a medicine liquid flow controller and a plurality of one-way valves. If only agricultural pesticide is backpacked, when the sprayer is used, the sprayer can suck field water along with the self proportioning with the agricultural pesticide and can obtain the mixed liquid of water and medicine with different proportioning at any time. Consequently the utility model not only alleviates the labor intensity of an operator, but also is favorable for the improvement of spray operation efficiency.
Description
The utility model is a kind of crops that are used for, and is particularly useful for the sprayer of rice field immunity desinsection.
At present, the knapsack sprayer that uses in the rural area needs in sprayer barrel water and agricultural chemicals to be mixed into finite concentration in advance, sprayer is born at back sprayed then.Because the content of sprayer inner bucket water substantially exceeds agricultural chemicals, the sprayer weight of filling mixed liquor is more heavy, and labor intensity of operating personnel is bigger, and especially for the personnel that carry out spraying operation for a long time, physical demands is very big.In addition, after the water medicine mixed liquor in the sprayer barrel uses up, need make up a prescription again to the limit, field and pour water, non-cutting time is longer, influences the operating efficiency of pesticide spraying.
The purpose of this utility model overcomes above-mentioned defective exactly, provides a kind of water source with the field to mix voluntarily with agricultural chemicals in the sprayer, to alleviate labor intensity of operating personnel, the sprayer of increasing work efficiency.
The utility model is to be made of parts such as rocking bar, connecting rod, pump, mixed solution container, medical liquid container, water aspirator and shower nozzles.One end of connecting rod is connected with rocking bar, and the other end is connected with the piston of pump.The lower end of pump is provided with check valve.Check valve is to be made of pellet shot from a slingshot and barrier element.Barrier element is used for preventing that pellet shot from a slingshot from jumping out, and it can be shaft-like or be drilled with the round sheet of aperture.The bottom of pump is connected with water aspirator with pipeline.The water aspirator middle part is hollow, and screen pack is equipped with in a side or both sides.Water aspirator preferably adopts the light material of proportion less than water, for example: timber, plastics, rubber etc.
Mixed solution container is provided with inlet and liquid outlet, and liquid outlet joins by pipeline and shower nozzle.Inlet and medical liquid container and pump pressure chamber join.Check valve is equipped with at the inlet place, and the structure of this check valve is consistent with the check valve of pump lower end.Check valve also is housed in the passage of medical liquid container and mixed solution container, and its position is located at the fluid passage that does not influence pump and mixed solution container and is advisable.The effect of this check valve only allows soup to flow into mixed solution container from medical liquid container.Also be provided with the medicinal liquid flow control valve in the passage of medical liquid container and mixed solution container, the flow with the control soup reaches needed medicine proportioning.In order to increase spray area, to increase work efficiency, sprayer can adopt a plurality of shower nozzles, is interconnected between each shower nozzle, only needs a switch control to get final product.
Because the utility model only carries soup, only need suck the water in field when making up a prescription, spray while making up a prescription.By the medicinal liquid flow control valve, also can obtain the different ratios that makes up a prescription at any time.This has not only alleviated operator's burden greatly, reduces physical demands, and easy to use, helps increasing work efficiency.Advantages such as that the utility model also has is simple in structure, easy manufacturing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1 shower nozzle.
Embodiment of the present utility model is: rocking bar (1) lower end is fixed on the housing (10) with connector (8).Connecting rod (2) one ends are connected with the rocking bar middle part, and an end is connected with piston (3).When rocking bar when connector is swung, connecting rod just driven plunger moves up and down.Pump (16), mixed solution container (20) and medical liquid container (11) are connected with a threeway element.The pressure chamber (4) of one termination pump of threeway element, the inlet of a termination mixed solution container, the liquid outlet of another termination medical liquid container.When moving on the piston, the pressure of pump pressure chamber (4) is less than atmospheric pressure, and the water in field is washed pellet shot from a slingshot (6) open and entered the pump pressure chamber by water aspirator (9).Rod-type barrier element (5) is used for preventing that pellet shot from a slingshot (6) from entering the pump pressure chamber.In addition, atmospheric pressure forces soup to open check valve (15), flow channel by the inlet (13) of medical liquid container.In order to improve the sensitivity of check valve, this check valve is made of circular metal plate, and the one side of sheet metal has boss, and the diameter of boss is approximately equal to the straight warp in hole (12).When piston moved down, pellet shot from a slingshot (5) was sealed hole (7), and sheet metal (15) is sealed hole (12), and water and soup are opened pellet shot from a slingshot (18) by the threeway element and entered mixed solution container (20).The top of sheet metal check valve (15) is provided with tabular medicinal liquid flow control valve (14), and the width of plate is slightly larger than the straight warp of pipe hole, is arranging the hole that diameter differs above, and the one end has scale.This plate is placed perpendicular to pipeline, by moving of plate, can change the diameter in hole that soup flows through, and reaches the purpose of control medicinal liquid flow.
Mixed solution container liquid outlet (21) is connected with shower nozzle (23) with switch (22) by pipeline.Present embodiment adopts two shower nozzles that are interconnected.Water aspirator (9) is wooden, and the middle part hollows out, and the one side that is hollowed out is equipped with screen pack.During use, water aspirator floats on the water surface in rice field, moves along with moving of people.
