Abstract
The utility model relates to a water suction device of a hand operated back type sprayer for spraying insecticide in agricultural production, which belongs to the technical field of agricultural production. The utility model is composed of a barrel body, a pressing rod, a three-way joint screwed with the lower end of the barrel body, and a barrel cap screwed with the upper end of the barrel body. The utility model is characterized in that a plurality of through holes are arranged on the wall of the barrel body near the barrel cap end; a flexible water suction body is wrapped on the pressing rod; because the flexible water suction body is wrapped on the pressing rod, physic liquor passing through the gap formed between a piston and the inner wall of the barrel body is sucked by the flexible water suction body; because the through holes are arranged on the wall of the barrel body near the barrel cap end, the physic liquor generated from squeezing the flexible water suction body flows out of the through holes when the pressing rod moves out of the barrel body, avoiding the physic liquor flowing to bodies of operators spraying insecticide from the drawn pressing rod. The utility model is favorable for safety production and health of operators; the utility model is suitable for making, matching and refitting the agricultural hand operated back type sprayers.
Description
Technical field
The utility model relates to a kind of parts in the sprayer of spraying insecticide in the agricultural production, relates in particular to the water absorber in a kind of agricultural hand-powered knapsack sprayer, belongs to field of agricultural production technologies.
Background technology
Agricultural hand-powered knapsack sprayer is extensive use of in agricultural production, be mainly used to spray insecticide, the control diseases and pests of agronomic crop, in the existing agricultural hand-powered knapsack sprayer vitals being arranged is water absorber, water absorber is by cylindrical shell, depression bar in the cylindrical shell, the threeway that the cylindrical shell lower end spins, the cover that the cylindrical shell upper end spins constitutes, the through hole that two symmetries are arranged on the cylindrical shell of nearly cover end, the centre bore of cover is passed in the upper end of depression bar, the intrinsic piston in the lower end of depression bar, during use, depression bar moves up and down in cylindrical shell under the effect of sprayer handle, soup flows out from the external port of export of threeway, depression bar is when moving upward, soup can be from gap that piston and cylinder inboard wall form by entering in the cylindrical shell more than the piston, and attach on depression bar, the soup that detaches on the depression bar of cover can trickle to the operating personnel's that spray insecticide back by the sprayer top, owing to spray insecticide all in damage by disease and insect summer and autumn occurred frequently, soup is easy to be penetrated on operating personnel's the skin and causes the harm of poisoning.Even use the soup that penetrates also to trickle in autumn and winter, can work the mischief to human body equally to operating personnel's clothes and human body surface.
Summary of the invention
The purpose of this utility model at the water absorber in the existing agricultural hand-powered knapsack sprayer because structural factor, above shortcomings when reality is used, provide and avoid soup to leak out in use, help the healthy agricultural hand-powered knapsack sprayer water absorber of operating personnel from depression bar.
The purpose of this utility model is achieved through the following technical solutions, the one, the water absorber in the agricultural hand-powered knapsack sprayer, comprise the depression bar in cylindrical shell, the cylindrical shell, the threeway that the cylindrical shell lower end spins, the cover that the cylindrical shell upper end spins, it is characterized in that on the barrel wall of nearly cover end some through holes being set the flexible water-absorbing body of parcel on the depression bar.
The utility model is by the flexible water-absorbing body of parcel on depression bar, the soup that passes through from the gap of piston and cylinder inboard wall formation is absorbed by flexible water-absorbing body, by on the barrel wall of nearly cover end, some through holes being set, can make depression bar outside cylindrical shell when mobile, the soup that the flexible water-absorbing body of extruding is produced flows out from through hole, avoided soup to trickle on one's body the operating personnel that spray insecticide from the depression bar of extracting out, help safety in production, help health of operators, the utlity model has very strong practicality, remarkable economic efficiency and social benefit, be applicable to and to make agricultural hand-powered knapsack sprayer supporting, also can be as the repacking of existing agricultural hand-powered knapsack sprayer.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 cylindrical shell, 2 through holes, 3 depression bars, 4 pistons, 5 flexible water-absorbing bodies, 6 catch, 7 dog screws.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by cylindrical shell 1, depression bar 3, the threeway that cylindrical shell 1 lower end spins, the cover that cylindrical shell 1 upper end spins constitutes, the centre bore of cover is passed in the upper end of depression bar 3, all the other place in the cylindrical shell 1, on 1 one sections walls of cylindrical shell of nearly cover end some through holes 2 are set evenly, the intrinsic piston 4 in the lower end of depression bar 3, be nested with flexible water-absorbing body 5 on 4/5ths depression bars of nearly cover end, be with catch 6 on the depression bar of flexible water-absorbing body 5 lower ends, catch 6 outsides have screw 7 to be screwed in location on the depression bar 3, the slightly larger in diameter of flexible water-absorbing body 5 is in cylindrical shell 1 internal diameter, and flexible water-absorbing body 5 is made of cavernous body.
Claims (4)
