Abstract
The utility model relates to an improved sprayer which comprises a barrel body, foot pumps, spray guns, an air compression barrel, a valve and a transfusion flexible pipe. The utility model is characterized in that only one transfusion flexible pipe connected with each foot pump is arranged and can lead liquid to be entered and discharged. The flexible pipe is connected with the air compression barrel and the barrel body through the by-pass end of a tee joint which is provided with a back valve in two pipe heads which are through. Both hands can hold a long spray gun to spray pesticide for a high plant or a plant which is positioned a long distance away. Or both hands respectively hold a short spray gun to spray pesticide for plants in a large area in a high efficiency mode. The utility model has the advantages of convenient usage and low cost.
Description
Technical field
The utility model relates to agricultural atomizer.
Background technology
The sprayer that widely use in present rural area is by a staving that backs on the body, manually (the row's medicine) liquid pump, tube connector, air compression cylinder, the valve that link with it and the spray gun formation of handing.Need a hand operated liquid pump when this spray spray apparatus uses, the hand-held short spray gun of another sprays medicine to crops.Its shortcoming one is that spray gun can not be grown, otherwise too heavy, and hand is taken incessantly, thereby can only be to closely or short crop spraying medicine, can not be to far away or high crop spraying medicine, and the 2nd, spray drug effect rate is low, can only hold a spray gun spray medicine, and can not spray medicine simultaneously by both hands.
For overcoming above-mentioned shortcoming, the inventor discloses in the patent No. is the patent documentation of ZL01227944.7 a kind ofly both can spray medicine (both hands are held a long spray gun) to remote or tall and big crop, can respectively hold a spray gun and the sprayer of high efficiency spray medicine by two hands again.
This sprayer is mainly by staving, pin pump, spray gun, air compression cylinder, and infusion tube and valve constitute, and its shortcoming is to need to join on each pin pump, one go out two infusion tubes, and that walking is got up is cumbersome, cost is also than higher.
Summary of the invention
But task of the present utility model is a kind of both both hands of design holds spray gun remote or tall and big crop is sprayed medicine, again can two hands respectively hold a spray gun and spray medicine, the flexible pipe on the pin pump is also fewer and make the also lower a kind of improved sprayer of walking, more convenient operation, cost simultaneously.
The utility model has adopted following technical measures:
A kind of improved sprayer comprises staving (1), pin pump (2), spray gun (3), air compression cylinder (4), connects therebetween infusion tube (5,6,7) and valve (8,9).Only be connected with one on the pin pump (2) and play the feed liquor effect when lifting pin, when stepping on, plays on pin the flexible pipe (7) of discharge opeing effect, the bypass termination of the other end of this flexible pipe (7) and a threeway (11) links, one end of two straight-through terminations of this threeway (11) links to each other with the bottom of described staving (1), the other end then links to each other with described air compression cylinder (4), and described spray gun (3) then connects what therebetween by another flexible pipe (7); One non-return valve (9,12) is respectively arranged in two straight-through terminations of threeway (11), open and make liquid inflow pin pump (2) under the effect of non-return valve (12) liquid in staving (1) in that termination that when pin lifts, links to each other with staving, when pin is stepped on pin pump (2), liquid one side in it closes this non-return valve (12), opens another non-return valve (9) that joins with air compression cylinder (4) and spray gun (3) on the other hand and liquid is sprayed by spray gun (3).
Described two non-return valves (9,12) constitute by pearl (91,11), block (92) and orifice plate (93): with that termination that described air compression cylinder (4) links to each other in the top of pearl (91) of non-return valve (9) have one can make it spacing but leave the block (92) that Kong Erke flows through liquid, the orifice plate (93) of one center bore less than bead diameter thereunder arranged, same with it direction, the non-return valve (12) in that the straight-through termination that links to each other bottom described staving (1) also is provided with pearl (91), block (92) and orifice plate (93) in the same way.
The spray gun spray medicine of can both hands when the utility model uses holding one long (weight) altogether also can one hand be respectively held the spray gun of a weak point (gently), be power with the step at a distance or the large tracts of land plant spray medicine.Owing to have only an infusion tube on every pin pump, not only walk conveniently, also can reduce cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of improved sprayer comprises the staving 1 that is used to hold soup.Two air compression cylinders 4 about being fixed with on the staving 1.One of two straight-through terminations of the bottom liquid outlet of air compression cylinder 4 and spray gun 3 (by flexible pipe 5) and threeway 11 (upper end) also connects, and another termination (lower end) of two terminations links to each other with the bottom of valve 8 with staving 1 by flexible pipe 6.The bypass ends of threeway 11 links to each other with pin pump 2 by flexible pipe 7.Pin pump 2 can be the liquid capsule of being made by the close material of the liquid of rubber or flexible plastic and so on, can be piston apparatus also, which is provided with the thing of bandage 10 and so on, when easy to use liquid pump 2 is fixed in the underfooting of correspondence.One non-return valve 9,12 is respectively arranged in two straight-through terminations of threeway 11, open and make liquid inflow pin pump 2 under the effect of non-return valve 12 liquid in staving 1 in that termination that when pin lifts, links to each other with staving, when pin is stepped on pin pump 2, liquid one side in it closes this non-return valve 12, opens another non-return valve 9 that joins with air compression cylinder 4 and spray gun 3 on the other hand and liquid is sprayed by spray gun 3.
Two non-return valves 9,12 constitute by pearl 91, block 92 and orifice plate 93: with that termination that air compression cylinder 4 links to each other in non-return valve 9 pearl 91 above have one can make it spacing but leave the block 92 that Kong Erke flows through liquid, the orifice plate 93 of a center bore less than bead diameter thereunder arranged; Same with it direction, with that straight-through termination that staving 1 bottom links to each other in non-return valve 12 also be provided with pearl 91, block 92 and orifice plate 93 in the same way.
As another kind of embodiment, air compacting barrel 4, spray gun 3 and pin pump 2 also can only be established a cover, and it is long that therefore spray gun 3 can be done, and both hands are armed during use, can give (high or short) plant spray medicine of big tree and so on.
