Description

Sprayer

The utility model relates to a kind of sprayer, in particular for the sprayer of farmland sprinkling.

Existing sprayer comprises container, fog-spray nozzle and piston cylinder, piston and the handle that links to each other with piston etc. of carrying liquid, during sprinkling, people with the sprayer back of the body piggyback, one hand-held fog-spray nozzle, pulling handle on the other hand moves up and down, handle drives piston by pull bar and moves back and forth in piston cylinder, and along with the reciprocating motion of piston, pipeline that liquid links to each other with container by piston cylinder and valve are inhaled into and lead to container pipeline, valve and fog-spray nozzle outward by piston cylinder again behind the piston cylinder and be sprayed onto on the crops.Because people carry on the back sprayer on shoulder, and in spray process, need not trading halt fixed handle to move up and down, therefore shoulder not only will bear the gravity of whole sprayer, but also wants the partial action power of receiving plate fixed handle, has so just increased operator's labour intensity.

For this reason, the purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of improved sprayer is provided, and it can reduce the labour intensity of operator in the sprinkling process under the situation that does not change sprayer size and weight.

The technical scheme that realizes the utility model purpose is a kind of sprayer, comprises the container of carrying liquid and the device that liquid is poured into, sprays, and its special character is that pin steps on pressurizing unit and be communicated with this container and fog-spray nozzle respectively by valve, pipeline.

And the three-way connection that pin is stepped on pressurizing unit is installed on the chamber wall, and valve is arranged in it, is provided with switch between it and flexible pipe, and the other end of flexible pipe links to each other with retracting cylinder, and the retracting cylinder top is provided with the device that itself and foot are connected.

And pin is stepped on the end that the water outlet one-way cock is housed in the three-way connection of pressurizing unit and is communicated with fog-spray nozzle after through poly-cylinder pressure.

And, pack into the device of container of liquid to be made up of piston and piston cylinder, set valve is a flowing water Valve in the pipeline between piston cylinder and container, set valve is an inlet valve from the pipeline in the connection external world that piston cylinder is drawn.

Because fog-spray nozzle is stepped on pressurizing unit with pin and is linked to each other, the operator applies active force to the retracting cylinder that pin is stepped in the pressurizing unit in the process of walking, be squeezed after making liquid in the container be inhaled into retracting cylinder, spray by fog-spray nozzle by poly-cylinder pressure, so just, having saved existing sprayer in use needs the limit to walk the action that the side plate fixed handle moves up and down, the force-bearing situation of operator's shoulder is improved, thereby reach the purpose that reduces labour intensity.

Below with reference to accompanying drawing the utility model is described in detail.

Accompanying drawing is a three-dimensional cutaway view of the present utility model.

The utility model equally has the container 20 of carrying liquid with existing sprayer as seen from the figure, the piston 2 that piston cylinder 1 is arranged in the container 20 and in piston cylinder 1, back and forth move up and down, piston 2 tops link to each other with handle 5 by tie-rod 3, different is will have valve set in piston cylinder 1 in the sprayer and the pipeline between the container 20 8 now and change outlet valve into by water intaking valve, the valve set the extraneous pipeline 6 of leading to of drawing from piston cylinder changes water intaking valve into by outlet valve, so just, make piston cylinder 1 and piston 2 become the mechanism of drawing water, after the spray liquid in the container 20 is intact, the operator will not unload from shoulder by sprayer, as long as suction pipe 7 one ends are enclosed within on container 20 and the extraneous pipeline that is communicated with, the other end is put into used solution, plate fixed handle 5 can suck solution in the container 20, certainly look the operator and require difference, the mechanism of also this cover can being drawn water removes with weight reduction and reduces cost, and still as existing sprayer solution is poured into container 20.In addition, it is fog-spray nozzle 4 to be stepped on pressurizing unit 17 by poly-cylinder pressure 21 backs with pin link to each other that another point of the present utility model improves, the three-way connection 10 that pin is stepped on pressurizing unit 17 is installed on the chamber wall, two is respectively through an one-way cock 18,19 back connection container 20 and poly-cylinder pressures 21, poly-cylinder pressure 21 is communicated with fog-spray nozzle 4 again, two check valves 18,19 placement directions are opposite, the other end of three-way connection 10 is communicated with retracting cylinder 15 by switch 11 and flexible pipe 16, retracting cylinder 15 can be made with rubber, if its elasticity is not enough, within it fixing spring or outside it clip to strengthen elasticity, know that by calculation of pressure and test retracting cylinder 15 highly only has 2-3cm, can not influence operator's walking, for prolonging the service life of retracting cylinder 15, can be thereon, wear-resisting hardboard 14(such as rubber slab are set) down, has the strap 13 that retracting cylinder 15 is fixed on foot on the hardboard 14, tether 12 etc., during work, the operator only needs retracting cylinder 15 tied up that (but bipod is tied up a retracting cylinder 15 respectively in foot, also can only establish one, single pin work), in the process of walking, the effect of being squeezed was from fog-spray nozzle 4 ejections after solution was inhaled into retracting cylinder 15, as stepping at pin in the pipeline 9 between pressurizing unit 17 and the fog-spray nozzle 4, set up a three-way connection, then can adorn two fog-spray nozzles 4, operator's two hands are worked simultaneously, increase work efficiency.The operator applies active force to retracting cylinder 15 in the process of walking, liquid sucked squeeze into poly-cylinder pressure 21 behind the retracting cylinder 15, by fog-spray nozzle 4 ejections that are communicated with poly-cylinder pressure 21, stepping on the purpose that poly-cylinder pressure 21 is set between pressurizing unit 17 and the fog-spray nozzle 4 at pin is in order to make fog-spray nozzle 4 obtain more stable flow rate and better spray effect then.
