[0039] Working principle: When working, firstly, water and fertilizer are put into the storage cylinder 401 through the feeding pipe 404, and then the first motor 406 is turned on to make the stirrer 405 rotate, so that the water and fertilizer are rotated to form water fertilizer, and then the trees are fertilized;

[0040] Move the mobile vehicle 1 to the position corresponding to the tree, so that the annular base 502 is sleeved on the outside of the tree, and then control the output end of the cylinder 5071 to move upward through the controller 3, push the push plate 5072 to move upward, and then drive the rotating sleeve 5066 to rotate around the circular disk 5063 through the connecting rod 5073, so that one end of the nozzle of the sprinkler 5065 is tilted downward, until the sprinkler 5065 is adjusted to the position where the sprinkler 5065 nozzle faces the tree and contacts the ground, close the push plate 5072, and then start the water pump 403, drive the water and fertilizer in the storage cylinder 401 to enter the inner cavity 5061 through the hose, and then enter the sprinkler 5065 through the fixed cylinder 5062 and the circular disk 5063, and finally pass through the gap between the conical surface 5094 and the conical block 5096 and spray out from the nozzle to the surrounding of the tree;

[0041] When the nozzle 5065 rotates downward, the second tooth plate 50914 on the circular block 50913 meshes with the first tooth plate 5093. When the nozzle 5065 rotates, the screw rod 50911 is driven to rotate, and the screw rod 50911 is threadedly connected with the sliding block 5098, thereby driving the transverse block 5095 to move transversely inside the nozzle 5065, so that the gap between the conical surface 5094 and the conical block 5096 increases, so that the amount of water and fertilizer sprayed per unit time increases. Since the greater the downward rotation angle of the nozzle 5065, the larger the diameter of the tree, the more water and fertilizer are sprayed, so that the amount of water and fertilizer is adaptively adjusted to the size of the tree, which is convenient for use;

[0042] At the same time, the second motor 5086 is turned on to rotate the gear 5085, and the gear 5085 is meshed with the tooth groove 5083 on the outer wall of the arc-shaped slider 5082, thereby driving the annular pipe 503 to move along the arc-shaped slide groove 5081, so that the two nozzles 5065 can move around the tree, which is convenient for fertilizing the tree in all directions. The curvature of the annular base 502 and the curvature of the annular pipe 503 are both greater than one hundred and eighty degrees, so that the annular pipe 503 will not disengage from the arc-shaped slide groove 5081 when rotating, thereby improving the stability of fertilization.
