The specific embodiment: The utility model is not limited by the following examples, and the specific implementation manner can be determined according to the technical scheme of the utility model and actual conditions.

Embodiment: As shown in Figures 1-4: the hand-held weeding and spraying machine is composed of a base 13, a shearing tool installed on the base 13, a turntable 15 and a piston pump 17 linked with the shearing tool are arranged above the base 13 The medicine box 6, and the pilot valve 3 and the slow nozzle that are communicated with the medicine box 6 are formed. There are three links in the guide valve 3, one of which is connected to the piston pump 17, and the other two links are respectively connected to the medicine outlet pipe 4 and the medicine suction pipe 5. Box 6 is connected. The shearing tool is a cross-shaped cutter composed of a fixed blade 10 and a movable blade 11. Both the fixed blade 10 and the movable blade 11 have a cutting part and a handle, and the opposite ends of the cutting part are sharpened. The handle of the fixed blade 10 is flexibly connected with the base 13, and the handle of the movable blade 11 is flexibly connected with a connecting rod 14 and a guide rod 16, the guide rod 16 is connected with the pump plug rod of the piston pump 17, the connecting rod 14 is connected with the turntable 15, and the turntable 15 is arranged on the base, driven by the motor.

As shown in Figure 3, a fixed bolt 12 is also arranged on the handle of the movable blade 11. When the motor cannot be used to drive the turntable 15, a push rod can be socketed on the fixed bolt 12 to push the movable blade 11 back and forth to open and close. It can also play the role of cutting grass and spraying medicine.

As shown in FIG. 2 , two of the three-way ports in the pilot valve 3 are respectively equipped with a medicine-absorbing one-way valve 8 and a medicine-discharging one-way valve 9 in opposite directions, and the other one is the piston pump interface 7 . The medicine suction one-way valve 8 connected with the medicine suction pipe 5 conducts when negative pressure is generated in the pilot valve 3, and closes when positive pressure is generated, and the medicine discharge one-way valve 9 connected with the medicine discharge pipe 4 generates pressure in the pilot valve 3. Closes on negative pressure and opens on positive pressure.

As shown in Figure 1, a handle 1 is installed at the rear end of the base 13, and a motor switch, a power cord, and a power cord jack can be arranged at the handle 1. In order to protect the rotating disk 15, the rotating disk 15 is covered with a rotating disk cover 2.

The medicine outlet pipe 4 is divided into two strands, and the injection end is socketed with a slow nozzle, and the slow nozzle is formed into a group by water-absorbing materials, such as sponge and cloth strip. Slow nozzle is attached to the back side of fixed blade 10 and movable blade 11. When the medicine passes through the slow nozzle, the injection pressure of the medicine will be relieved, so that the medicine can be evenly and slowly dripped on the plants.

When the device works, the medicine box 6 is filled with medicines, such as: herbicides, insecticides, if there is a power supply, plug in the power supply in the jack, the switch is opened, the device starts to work, the motor drives the rotating disk 15, and the rotating disk 15 drives the connecting rod 14. The connecting rod 14 drives the movable blade 11, so that the movable blade 11 and the fixed blade 10 are opened and closed repeatedly, so as to realize the purpose of mowing grass. The opening and closing of the movable blade 11 drives the guide rod 16 to move repeatedly, and the guide rod 16 drives the piston pump 17 to work. When the piston pump 17 takes medicine, the medicine suction check valve 8 is opened, and the medicine delivery check valve 9 is closed; Finally, the medicine drips out from the slow nozzle, so as to realize the purpose of dripping medicine while mowing the grass.

The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect, and non-essential technical features can be increased or decreased according to actual needs to meet the needs of different situations.
