[0014] A fertilization method for a mechanized fertilization device in an oil-tea camellia forest land includes the following steps:

[0015] S1: Install a fertilizer tank on the top frame, pour liquid fertilizer into it, connect one end of a hose to the fertilizer tank, and the other end to the one-way liquid inlet valve;

[0016] S2: Control the reversing motor and the traveling motor to make the device travel in the oil-tea camellia forest and move it to a suitable position away from the oil-tea camellia trees;

[0017] S3: Control the motor to rotate, make the plug arrows swing and insert into the soil, and drive part of the soil to break away from the ground to form a fertilizer injection groove;

[0018] S4: The liquid inlet piston pipe and the draw pipe move relative to each other, changing the pressure in the formed area, sucking the liquid fertilizer into the area formed by the liquid inlet piston pipe and the draw pipe, and spraying it out from the one-way liquid outlet valve into the fertilizer injection groove;

[0024] 1. This device is driven by a motor and uses the limit of card slots and chutes to combine the lateral swinging excavation action and the longitudinal insertion action, facilitating better excavation of the plug arrow designed in an arrow shape. The spaced plug arrows reduce the resistance of excavation, and at the same time, fertilizer is sprayed at each spaced position, enabling uniform distribution of the fertilizer liquid. The mounting plate reciprocates relative to the plug arrow to scrape off the soil carried out by the adjacent plug arrow grooves. When the side plates move towards the middle, they drive the soil towards the middle. When the side plates move outwards, they swing under the obstruction of the soil, facilitating the backfilling of the grooves opened by the plug arrows.

[0025] 2. The liquid inlet piston tube and the draw tube of this device form a suction and discharge liquid area. The movement similar to that of a piston cylinder is combined with the help of two one-way valves to achieve the suction and spraying of liquid fertilizer. The one-way liquid inlet valve can only allow the passage of liquid and gas, and the one-way liquid outlet valve can only spray liquid and gas downwards.

[0055] A fertilization method for a mechanized fertilization device in an oil-tea camellia forest land includes the following steps:

[0056] S1: Install a fertilizer tank on the top frame 1, fill it with liquid fertilizer, connect one end of a hose to the fertilizer tank, and the other end to the one-way inlet valve 36;

[0057] S2: Control the reversing motor 3 and the traveling motor 5 to make the device travel in the oil-tea camellia forest and move it to a suitable position from the oil-tea camellia tree;

[0058] S3: Control the motor 14 to rotate, so that the plug arrow 35 swings and inserts into the soil, and part of the soil is taken away from the ground to form a fertilizer injection groove;

[0059] S4: The liquid inlet piston tube 38 and the draw tube 40 move relative to each other, causing the pressure in the formed area to change, sucking the liquid fertilizer into the area formed by the liquid inlet piston tube 38 and the draw tube 40, and spraying it out from the one-way outlet valve 41 into the fertilizer injection groove;

[0060] S5: When the side plates 21 move towards the middle position, they scrape the soil into the fertilizer injection groove. When the side plates 21 move towards both sides, they swing under the action of soil resistance;

[0061] S6: The rollers 16 compact the fertilizer injection groove of the backfilled soil during the forward movement.

[0062] The liquid inlet piston tube 38 and the draw tube 40 of the device form a liquid pumping and discharging area. The movement similar to that of a piston cylinder is combined with the aid of two one-way valves to achieve the pumping and spraying of liquid fertilizer. The one-way inlet valve 36 can only allow liquid and gas to pass through, and the one-way outlet valve 41 can only spray liquid and gas downward. The liquid inlet piston tube 38 is hollow and its outer surface is rubber, which is sealed with the draw tube 40 to achieve liquid spraying. The mounting small plate 39 reciprocates to scrape off the soil brought out by the adjacent plug arrows 35 during slot digging.

[0063] The arrowhead design of the plug arrow 35 enables better excavation. Following the rotation of the upper turntable 20 and with the limitation of the card slot 17 and the sliding slot 27, etc., the combination of the lateral swinging excavation action and the longitudinal insertion action is achieved. The spaced plug arrows 35 are designed to reduce the excavation resistance, and at the same time, fertilizer can be sprayed at each spaced position, so as to achieve the uniform distribution of fertilizer liquid.

[0064] This device is driven by a motor 14 and limited by a card slot 17 and a chute 27, etc., to combine the lateral swinging excavation action with the longitudinal insertion action, facilitating better excavation by the plug arrow 35 designed in an arrow shape. The spaced-apart plug arrows 35 reduce the resistance of excavation, and fertilizer can be sprayed at each spaced position, enabling the uniform distribution of fertilizer liquid. The mounting small plate 39 reciprocates relative to the plug arrow 35 to scrape off the soil carried out of the groove dug by the adjacent plug arrow 35. When the side plate 21 moves towards the middle, it drives the soil to approach the middle. When the side plate 21 moves outwards, it swings under the obstruction of the soil, facilitating the backfilling of the groove dug by the plug arrow 35.

[0065] The liquid inlet piston tube 38 and the draw tube 40 of this device form a liquid pumping and discharging area. Similar to the principle of a piston cylinder or a syringe, the suction and spraying of liquid fertilizer are achieved with the help of two one-way valves. The one-way liquid inlet valve 36 can only allow the passage of liquid and gas, and the one-way liquid outlet valve 41 can only spray liquid and gas downwards. The liquid inlet piston tube 38 is hollow and its outer surface is rubber, which is sealed with the draw tube 40, achieving liquid spraying. Moreover, the spraying angle continuously changes, enabling it to contact the soil evenly, resulting in better fertilization effect and higher efficiency.

[0066] The specific embodiments of the present invention disclosed above are only for illustration. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
