Abstract

The utility model relates to a hand self-air high efficiency sprayer, which is an agricultural medicine-spraying device. When used, a physic liquor box can be automatically inflated only pushing a walking air pump; a group of adjustable nozzles can be complementary; each position of the crops can be favored; the loading quantity is more; the labor intensity is low; the spraying is rapid and even; the hand self-air high efficiency sprayer can spray the crops with different heights and different row spacing, and the application range is wide. The hand self-air high efficiency sprayer has the advantages of simple structure, low cost, safe performance, light weight, and convenient carrying. An air pump in a hand device can be also used for inflating for other machines, such as a row vehicle, a tricycle, a bicycle, etc.

Description

Hand self-air high efficiency sprayer

The utility model hand propelled is a kind of spray liquid device from inflating the efficient spray device, belongs to agricultural plant protection machinery.

In the prior art, agricultural atomizer mainly contains following deficiency: big-and-middle-sized power driven sprayer, not only cost is very high, and main frame can not enter the field, only is used for fruit tree and forestry control.Can enter the sprayer in field, no matter non-power driven sprayer, or the higher equipment of small motor sprayer of cost, generally adopting backpack, labour intensity is big, and the operator is very easily tired; Explosive payload is few, and round powder charge influences the sprinkling progress often; Shower nozzle is few, and a shower nozzle generally only is housed, constantly mobile shower nozzle and change injection direction, could guarantee to spray quality, so just limited spray drug effect rate, and this operation, shower nozzle constantly all will be under the people watches attentively, when walking about down with the wind, shower nozzle must be in windward, easily causes pesticide poisoning.

The utility model hand propelled is from the purpose of inflating speed sprayer, a kind of agricultural equipment for plant protection that designs at above-mentioned defective just.Its technical conceive is: air pump, spray tank, sprinkler part etc. are installed on the dolly.Be provided with a plurality of shower nozzles, each shower nozzle can transfer to desired height and required sprinkling direction with spray boom, and realizing walks about fast can guarantee that also spray liquid is even, and the position is accurate; Shower nozzle is being operated at preceding equal energy with shower nozzle after one's death.The wheel rotating band pump of taking offence to the spray tank inflation, need not stop and inflate; Less demanding because of operating pressure, so air pump is selected for use a kind of simple in structure, the efficient height, require low single blade oscillating formula air pump.Be provided with air pressure automatic control valve, when the medicine-chest internal gas pressure reached selected air pressure, the air pump operating conditions was pressed onto atmospheric pressure from atmosphere, air pump this moment loss motive force hardly.Need only promote walking during use.

Effect of the present utility model; Easy and simple to handle, can a people promote, the weakling also can two people one hold up one to draw.Wheel drives air pump and inflates to spray tank, only needs to promote walking, just even spray liquid, and explosive payload is many, and labour intensity reduces, the operating efficiency raising.One group of shower nozzle complements each other, and emphasis can be arranged looks after each position of crop, need not to watch attentively shower nozzle, and can guarantee to make shower nozzle to spray medicine in leeward all the time, and is safe and reliable, simple in structure, is convenient to safeguard that cost is low, and is in light weight, is easy to carry.Can spray height difference, the different multiple kinds of crops of line-spacing, adapt to wide.Air pump in hand this device also can be other facility (as row's car, tricycle, bicycle etc.) inflation, also can be used to buy and sell gas from a container to another container.A tractor serves several purposes, high efficiency.

The technical solution of the utility model will be further described in conjunction with the accompanying drawings and embodiments.
