Abstract

The utility model relates to an agricultural chemical spraying machine. The utility model comprises a motor, a centrifugal atomizing disk, a physic liquor reserving container, and liquid conveying pipelines. The motor is supplied with the power supply by an accumulator or a dry battery. The utility model is characterized in that the upper side of the liquid conveying pipeline which is arranged between the physic liquor reserving container and the centrifugal atomizing disk is provided with an elastic liquid chamber. The upper sides of the liquid conveying pipelines of both ends of the elastic liquid chamber are respectively provided with a one-way valve, which causes a spray head to be used conveniently under the condition that the height of the spray head is higher than the height of the liquid level of the physic liquor reserving container. The utility model has the advantages of convenient spraying for crops with tall rods, low labor intensity, and uniform spraying. Simultaneously, because the sprayer uses an accumulator or a dry cell as the energy source, the cost is lower, and the manufacturing cost is also cheap.

Description

A kind of micropower power spraye

The utility model relates to a kind of pesticide spray machinery.

Present existing electronic pesticide spray machinery, its medicine container and centrifugal atomizing shower nozzle are fixed into integral body, and the user is when spraying high bar crops, need manpower to lift shower nozzle and medicine container, labour intensity is big, and for this reason, the volume of medicine container also is very limited; The spraying mechanical that also has a kind of miniature gasoline engine to drive, the fault rate of the higher gasoline engine of its price is also higher; And widely used hand sprayer, not only labour intensity is big, simultaneously because the power that the operator uses is unbalanced, makes the uniformity of spraying can not get guaranteeing, influences the plant protection operation quality.

The purpose of this utility model be to provide a kind of can be easily to high bar crops or low bar crops spraying medicine, and the uniform micropower power spraye of spraying.

The purpose of this utility model is realized by following mode.

Sprayer described in the utility model, include electromotor, the centrifugal atomizing dish, liquid holding container and liquor charging pipeline, this electromotor provides power supply by accumulator or dry cell, it is characterized in that the drug delivery pipeline between liquid holding container and the centrifugal atomizing dish is provided with an elasticity liquid chamber, be respectively equipped with check valve on the liquor charging pipeline at these elasticity liquid chamber two ends.

The utility model still can normally use its shower nozzle owing to have additional check valve and elasticity liquid chamber between liquid holding container and shower nozzle under the situation that is higher than the liquid holding container liquid level.When high bar crops are sprayed, the operator medicine container can be born on one's body, soup flows into the elasticity liquid chamber through check valve in container, when the operator pushed the elasticity liquid chamber with hand, this check valve stoped soup to flow backwards, and then soup is extruded to the centrifugal atomizing shower nozzle ejection of high position, as operator during with openhanded opening, the check valve in back stops pipe inner product liquid storage body to blow back into the elasticity liquid chamber, and soup has entered the elasticity liquid chamber from medicine container again, and one squeezes a pine works continuously.Because the medicine container of this sprayer back of the body on one's body the operator, when the bar crops are hanged down in sprinkling, does not need hand extruding elasticity liquid chamber, just can conveniently spray.Easy to use, labour intensity is low, and that uses in the also comparable existing power spraye of its liquid holding container is much bigger, helps carrying out continuously of the work of spraying.

In order to make spraying evenly, the utility model can also be provided with one section elastic hose on the liquor charging pipeline between back check valve and centrifugal atomizing shower nozzle, like this, the operator is when pushing or unclamping the elasticity liquid chamber, two check valves are alternately opened or closure, soup is constantly flowed in the shower nozzle, because elastic hose has a small amount of liquid storage effect, it is more even that soup is flowed.

Sprayer of the present utility model, structure are comparatively simple, compare with existing hand sprayer, have laborsavingly, and the spraying advantage of uniform is compared with existing power spraye, use more conveniently, and especially to the sprinkling of high bar crops, labour intensity is low, and fault rate is low; And low cost, it is also lower to use accumulator to make energy cost.

Accompanying drawing below by embodiment is further described.

Fig. 1 is a kind of example structure schematic diagram of the present utility model, among the figure, (1) is the centrifugal atomizing shower nozzle, it is installed on the output shaft of micromachine (2), the elongator of this motor housing is connected on handle (3) outer wall, liquid pushing tube (7) will be contained explosive barrel (9), elasticity liquid chamber (6) is connected in aggregates with the centrifugal atomizing shower nozzle, be provided with preceding check valve (8) in the exit of beverage container, the elasticity liquid chamber is soft elastic tube (4) to the some of the liquid pushing tube of shower nozzle, and it passes from the inner chamber of handle, check valve (5) after the upper port of handle is, the external power supply of micromachine is accumulator (10), and it places contains on the explosive barrel wall.When using the present embodiment spraying, the operator will contain explosive barrel by braces and back on the body, grasp handle (3) then, can be to short plant spraying operation, when long-stalked crop was sprayed, the operator need push the elasticity liquid chamber with another hand, and the soup that will accumulate in this coyote hole through check valve (5) squeezes out shower nozzle, unclamp then, the soup of containing in the explosive barrel flows into the elasticity coyote hole again.Because the effect of check valve (5), the soup that is trapped in shower nozzle and the elastic hose (4) can not flow backwards.The flow device (11) of centrifugal atomizing shower nozzle has throttling action, and the pressure in the elastic tube is raise, and elastic tube expands slightly, and this elastic force effect also helps soup evenly ejection continuously.

Present embodiment in actual use, because the flow device of centrifugal atomizing shower nozzle can be changed, flow device aperture is big, and the liquid of outflow is many, and fogdrop diameter is big, the spray liquid diameter is big, otherwise fogdrop diameter is little, and the diameter that liquid sprays is little, the operator can select as required, to adapt to different use occasions.

The accumulator emergency light is more in the market, and its structure is very compact, and for convenience, the utility model also can be used as the energy.

Claims (2)

1. micropower power spraye, include electromotor, the centrifugal atomizing dish, liquid holding container and liquor charging pipeline, this electromotor provides power supply by accumulator or dry cell, it is characterized in that the liquor charging pipeline between liquid holding container and the centrifugal atomizing dish is provided with the elasticity liquid chamber, be respectively equipped with check valve (5), (8) on the liquor charging pipeline at these elasticity liquid chamber two ends.

2. sprayer according to claim 1 is characterized in that described centrifugal atomizing shower nozzle to the liquor charging pipeline between back check valve (5) is provided with one section elastic hose (4).
