The right sides of the front and back of the base are respectively rotatably connected to the inner sides of two rollers. For this efficient liquid fertilizer spraying device for landscape gardening planting, through the cooperation of mechanisms such as a stirring barrel and a controller, the servo motor is controlled to rotate. The servo motor drives the metering wheel to rotate so that the metering groove rotates below the through hole. The fertilizer in the fertilizer hopper enters and fills the metering groove under the action of gravity through the through hole. When the metering groove rotates above the feeding pipe, the fertilizer in the metering groove enters the stirring barrel through the feeding pipe, thereby realizing the regulation of the fertilizer input dose by controlling the number of rotations of the servo motor.

[0014] The present invention provides an efficient liquid fertilizer spraying device for garden planting. It has the following beneficial effects: (1) In this invention, when the wheel rotates, it drives the second support plate to move up and down. When the second support plate moves up and down, it can contact the first hollow baffle. When the second support plate contacts the first hollow baffle, the first hollow baffle will rotate up and down. When the first hollow baffle rotates up and down, it drives the nozzle to move up and down. When the first triangular inclined block and the second triangular inclined block contact the long plate, it can drive the nozzle to turn left and right. When the nozzle turns up, down, left, and right, the rotation of the nozzle can increase the spraying range of the liquid fertilizer, thereby achieving efficient fertilization. When the first column moves up and down, it can drive the threaded telescopic rod to expand and contract. When the threaded telescopic rod expands and contracts, the liquid in the machine body will flow into the nozzle through the soft water pipe and be sprayed out, which can effectively prevent the liquid in the machine body from flowing out through the gap.

[0015] (2) In this invention, the rotation of the wheel can drive the first support rod to move up and down. When the first support rod moves up and down, it will drive the air pump rod to move up and down. Through the cooperation of the air pump rod and the air pump, the air outside the machine body can be compressed into the machine body, thereby increasing the pressure inside the machine body. When the pressure inside the machine body increases, the liquid inside the machine can be sprayed out from the nozzle. When the first support rod moves up and down, it will drive the guide block to move up and down. Since the guide block slides in the chute, when the guide block moves up and down, it will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the fan blade to rotate. The rotation of the fan blade can stir the liquid inside the machine, which can effectively prevent the liquid fertilizer from not being fully mixed in the water, resulting in uneven absorption of fertilizers by the crops that need fertilizers. There may be a phenomenon that some crops absorb too much or too little fertilizers, leading to infertility of the crops.

[0016] (3) In this invention, by removing the second sealing cap, liquid fertilizer can be injected into the fertilizer pipe. The liquid fertilizer entering the fertilizer pipe will enter the fertilizer tank. When the injection of the liquid fertilizer is completed, the second L-shaped floating block will rise along with the water level line of the liquid fertilizer to block the fertilizer pipe to prevent the liquid fertilizer from continuing to enter the fertilizer tank and wash away the first L-shaped floating block. By injecting water from the water inlet, the water will overflow the first L-shaped floating block, and the water level line will drive the first L-shaped floating block to rotate, thereby opening the fertilizer tank. The liquid fertilizer in the fertilizer tank will flow into the machine body and mix with the water. The use of fertilizers can be controlled according to the amount of water added, preventing the phenomenon of too much water and too little fertilizer or too little water and too much fertilizer from affecting the planted crops.
