DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] A device for deep application of liquid fertilizer and pesticide in an orchard comprises a shoulder-type manual sprayer 1, wherein the manual sprayer 1 comprises a liquid supply hose 101, wherein the liquid supply hose 101 is connected with a deep application pipe 2, wherein a plurality of liquid outlet holes 201 are formed at one end of the deep application pipe 2 away from the liquid supply hose 101, wherein a pedal 4 is installed on the deep application pipe 2, wherein the distance between the pedal 4 and the liquid outlet hole 201 is adjustable, and a valve 3 is installed between the liquid supply hose 101 and the deep application pipe 2.

[0030] Reference Figure 1-Figure 5, through a shoulder-type manual sprayer 1, liquid fertilizer can be carried on the shoulder for use in narrow terrain, and the pedal 4 is stepped on to facilitate the insertion of the deep application pipe 2 under the ground where fertilizer is required, and the distance between the pedal 4 and the liquid outlet 201 is adjusted. The pedal 4 is against the ground to adjust the insertion depth of the liquid outlet 201. Finally, the valve 3 is used to allow the liquid fertilizer in the liquid supply hose 101 to pass through the deep application pipe 2 and finally through the liquid outlet 201 for deep fertilization.

[0031] The valve 3 includes a valve tube 301 which is perpendicular to and through-connected to the deep application tube 2, a valve core 302 which is rotatably arranged on the valve tube 301 and has a through hole 3021, a shaft 303 which is coaxially fixed with the valve core 302 and passes through the valve tube 301, a dial plate 304 fixed on the shaft rod 303, and a spiral spring 305 fixed between the shaft rod 303 and the valve tube 301. A handle 202 is fixed to one end of the deep application tube 2 close to the dial plate 304.

[0032] Reference Figure 3-Figure 5 , the dial plate 304 is placed on one side of the handle 202, and under the action of the spiral spring 305, the through hole 3021 is in a state perpendicular to the deep application tube 2, and the through hole 3021 is blocked by the inner wall of the valve tube 301. At this time, the valve 3 is in a closed state. When fertilization is needed, the thumb is used to dial the dial plate 304, so that the shaft 303 drives the valve core 302 to rotate clockwise, and the through hole 3021 is connected with the deep application tube 2. At this time, the valve 3 is in an open state.

[0033] A limit rod 306 is fixedly mounted on one end of the valve tube 301 close to the dial plate 304 .

[0034] Reference Figure 3 The limit rod 306 is fixed in front of the valve tube 301 to prevent the spiral spring 305 from driving the valve core 302 to deflect excessively, resulting in the through hole 3021 being connected with the deep application tube 2 and causing overflow.

[0035] The pedal 4 is threadedly connected to the deep application pipe 2, and the deep application pipe 2 is provided with scale grooves 203 distributed axially at equal intervals.

[0036] Reference Figure 2 The pedal 4 is threadedly connected to the deep application tube 2 to facilitate adjustment of the height of the pedal 4.
