Technical field

The invention relates to the field of agricultural spray equipment, in particular to a hand-push single-wheel multi-purpose electric spray vehicle. the

Background technique

Traditional knapsack sprayers are labor-intensive and inefficient. And because the human body is not separated from the sprayer, once the sprayer produces problems such as running, escaping, dripping, leaking, etc., it will greatly endanger human health. Motorized sprayers, vibration, noise and phytotoxicity also directly endanger the health of farmers. According to investigations, within a week after the spraying season, farmers often feel dizzy and nauseated, but due to poor health awareness, they do not think this is a poisoning phenomenon, and the next spraying will continue in the usual way; some farmers carry the medicine box on their backs for a long time , due to the vibration of the medicine box and the leakage of medicine, the buttocks muscles are often ulcerated. the

Existing self-propelled sprayers are basically installed on elevated motor vehicles, which improves the working environment, but this kind of mechanical structure is complicated and expensive, and is not suitable for small farmers. The existing hand-push sprayer cannot enter the ridge of the field to administer medicine due to the obstruction of the crops. It is mostly used for fruit trees in the garden, or it needs to drag a very long spray pipe to suck the medicine from the medicine box placed in a wide space. It is troublesome that one person cannot complete the spraying process, and it is inconvenient to spray. the

Therefore, small farmers are reluctant to use the aforementioned sprayers. the

Detailed ways

The present invention will be further described below in conjunction with drawings and embodiments. the

The hand-push single-wheel multi-purpose electric spray vehicle is mainly composed of a frame traveling mechanism, an electric spray system and a spray boom support system. The traveling mechanism of the vehicle frame adopts a hand-push single-wheel structure and is composed of a guide wheel 1, a left support leg 2, a right support leg 3, a wheel frame 4 and a vehicle frame 5. Wherein the guide wheel 1 is arranged in a symmetrical triangle with the left support leg 2 and the right support leg 3 . The electric spray system includes a battery 6, an electric water pump 7, a liquid storage tank 8 and a liquid pipe 9; ) is located slightly behind the axle. The spray boom support system consists of a spray boom 10 and a stand supporting the spray boom. The stand includes a left vertical pole 12, a right vertical pole 13 and a left crossbar 15 fixed on the left and right vertical poles through a square limit beam 14. and right crossbar 16. The bottom of the left vertical bar and the right vertical bar has a series of folding mechanisms 17 and 18 that can be bent vertically, and the left cross bar and the right cross bar have secondary folding mechanisms 19 and 20 that can be bent laterally. The spray bar is arranged on the left cross bar and the right cross bar through buckles 21. The switch 22 of the electric spray system is designed at the handle of the trolley, so that the operator can easily control the equipment. the

The sprayer uses a battery as a power source to drive a small electric pump. When working, as shown in Figure 1, fill the liquid storage barrel with medicine, turn on the switch, the medicine liquid is driven by the micro electric pump to extract the medicine liquid, and the medicine liquid is sent to the nozzle 10 by pressurization, and sprayed out through the nozzle 11 . The whole device is placed on a small wheelbarrow, and when working, just turn on the switch and push the small cart. The boom can move up and down along the stand to adapt to crops of different heights. The spray boom can be folded, and the spray boom is unfolded during work. In this embodiment, the arm span can reach 4 meters, which improves the working efficiency. Multiple nozzles are installed on the spray boom. the

Considering that the spray boom and the stand are too long and take up too much space, it is not conducive to normal storage.
