DETAILED DESCRIPTION

[0017] like Figure 1-3 As shown, an agricultural water and fertilizer spraying device includes a liquid storage box 1 for storing water and fertilizer. The upper end of the liquid storage box 1 is provided with a liquid inlet 2, and a sealing cover 3 is threadedly connected to the liquid inlet 2. The device also includes a reverse spray mechanism 4 and a positioning spray mechanism 5. The reverse spray mechanism 4 is arranged at the bottom of the liquid storage box 1 and is used to spray water and fertilizer on the back of leaves. The positioning spray mechanism 5 is fixedly connected to the bottom of the reverse spray mechanism 4 to spray a pressure water column along the length direction of the device, and the device is plugged into the ground and fixedly placed.

[0018] like Figure 1-4As shown, in order to spray water and fertilizer on the bottom of the leaves of crops, the reverse spray mechanism 4 includes a connecting pipe 6, a connecting pipe 7 and a nozzle 8. The connecting pipe 6 is arranged at the bottom of the liquid storage box 1, and one end of the connecting pipe 6 is connected to the liquid storage box 1. A water pump 9 is arranged on the bottom wall of the liquid storage box 1, and the water outlet end of the water pump 9 is connected to one end of the connecting pipe 6. The connecting pipe 6 is U-shaped, and the connecting pipe 7 is connected to the outer wall of the connecting pipe 6. The connecting pipe 7 is inclined, and the connecting pipe 7 is symmetrically arranged at even intervals and distributed on the vertical outer wall of the connecting pipe 6. The nozzle 8 is connected to the end face of the connecting pipe 7 and is connected to the connecting pipe 7. The water pump 9 extracts the water and fertilizer in the liquid storage box 1 and pumps it into the connecting pipe 6. The internal pressure of the connecting pipe 6 increases, and the water and fertilizer are sprayed through the connecting pipe 7 inclined upward, so that the water and fertilizer act on the bottom wall of the blade. At the same time, according to the fixed position of the device, the connecting pipe 7 and the nozzle 8 are sprayed on the upper wall of the crop leaves.

[0019] like Figure 2-4 As shown, in order to realize the plug-in fixation of the device and meet the sprinkler irrigation of water and fertilizer, the positioning spraying mechanism 5 includes a spraying pipe 10, the spraying pipe 10 is fixedly connected to the center of the bottom wall of the connecting pipe 6, the spraying pipe 10 is connected to the connecting pipe 6, and the end of the spraying pipe 10 close to the connecting pipe 6 is provided with a solenoid valve 11 for opening and closing control of the spraying pipe 10, and the middle section of the outer wall of the spraying pipe 10 is fixedly connected with a baffle 12 for positioning and supporting the spraying pipe 10. The spraying pipe 10 is a hollow tube and can be directly inserted into the soil. The pump 9 extracts the water and fertilizer from the liquid storage box 1, and after pumping them into the connecting pipe 6, the solenoid valve 11 at the upper end of the spraying pipe 10 is opened to allow the water and fertilizer to enter the spraying pipe 10. A rubber valve 13 is provided inside the spraying pipe 10 at one end away from the connecting pipe 6. The rubber valve 13 increases the pressure of the spraying pipe 10 for fertilization. The squeezing force of the rubber valve 13 is less than the pressure sprayed by the nozzle 8, and at the same time, soil is prevented from entering the inside of the spraying pipe 10. Under the auxiliary support of the baffle 12, the spraying pipe 10 is inserted into the soil to realize the plug-in fixation of the device.

[0020] A handle 14 is fixedly connected to the upper portion of the liquid storage box 1 to facilitate the lifting and carrying of the device.

[0021] When in use, the operator opens the upper cover 3 and pours the mixed water and fertilizer into the liquid storage box 1. According to the use requirements, the device can be held for spraying, or the device can be inserted into the soil for positioning and spraying. The water pump 9 is driven to extract the water and fertilizer in the liquid storage box 1 and pump it into the connecting pipe 6. In the initial state, the solenoid valve 11 is in a closed state, the pressure in the connecting pipe 6 increases, and the water and fertilizer are sprayed from the nozzle 8 through the inclined connecting pipe 7 to achieve water and fertilizer spraying on both sides of the crop leaves.

[0022] When sprinkler irrigation is needed, the spraying pipe 10 is inserted into the soil and close to the plant roots, and the solenoid valve 11 is opened to allow the water and fertilizer in the connecting pipe 6 to enter the spraying pipe 10. Under the squeezing action of the rubber valve 13, the water and fertilizer are sprinkled on the plant roots.
