The lifting support legs can be hand-operated or electric, and are not limited in the embodiment of the utility model.

In one embodiment, the frame 1 is provided with a liquid level indicator 18, and the liquid level indicator 18 is connected to the water storage tank 2. The operator can observe the remaining water storage in the water storage tank 2 via the level gauge 18.

The following describes the implementation principle of an intelligent watering vehicle according to an embodiment of the present utility model with reference to fig. 1 and 4: the automatic navigation device 6 is utilized, the intelligent watering vehicle can automatically and accurately run to each watering point to carry out watering operation, watering deviation is difficult to carry out, the watering effect is improved, moreover, by utilizing the rotatable setting of the water outlet mechanism 3, an operator can adjust the water outlet mechanism 3 to a proper water outlet angle, the intelligent watering vehicle can aim at vegetation and seedlings to wait for watering when reaching the watering point to carry out watering operation, the survival rate of vegetation seedlings is improved, and water resource waste is reduced.

The intelligent watering cart adopts the large-scale water storage tank 2 with the water capacity of 5 tons, the operation range of the water storage tank 2 after single water addition is larger, and the operation efficiency is improved. The intelligent watering vehicle is powered by the generator 13, so that sufficient electric quantity can be provided, and the operation range of the intelligent watering vehicle is improved. The water outlet control system 4 can realize the watering operation of timing and quantification, ensure the watering effect and improve the vegetation survival rate.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The above-described embodiments of the utility model are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
