[0021] See Figure 1~3 In the embodiment of the present invention, a pesticide spraying device with weed removal function includes a base 1, a universal wheel 22 is installed at the bottom of the base 1, and two front and rear push rods are fixedly provided on the left side of the top of the base 1 2; The top of the base 1 is fixedly provided with a mixing box 16, the right side of the top of the mixing box 16 is provided with a feeding port 21, the feeding port 21 is connected with a cover, the top center of the mixing box 16 is fixedly provided with a first motor 17 , The first motor shaft at the bottom of the first motor 17 passes through the bottom wall of the mixing box 16 and is fixedly connected with a first rotating shaft 18, the first rotating shaft 18 is located in the mixing box 16, and the left and right sides of the first rotating shaft 18 are fixedly installed with a number of mixing The blades 19 and the left and right mixing blades 19 are arranged staggered to increase the mixing range. The bottom end of the first rotating shaft 18 is also fixedly installed with a spiral blade 20. Pesticide and water are added to the mixing box 16, and the mixing blade 19 and the spiral blade 20 rotate During stirring and mixing, when the spiral blade 20 rotates, the liquid at the bottom of the mixing box 16 is driven to move upward, thereby causing the pesticide to roll up and down, improving the mixing effect and mixing efficiency;

[0022] A pesticide box 4 is fixedly arranged on the left side of the top of the base 1, a number of pesticide bottles 5 are fixedly arranged in the pesticide box 4, a pesticide addition port 6 is provided on the top of the pesticide bottle 5, and the pesticide addition port 6 is connected with a cap. 5 The material is made of transparent plastic, which is convenient for observing the remaining amount of pesticide; the upper left side of the mixing box 16 is fixedly provided with a pressure cylinder 10 through a bracket, and the bottom left side of the pressure cylinder 10 is connected with a medicine feeding main pipe 8, which is connected with several medicine feeding pipes. The branch pipe 7, the main medicine feeding pipe 8 and the medicine feeding branch pipe 7 are arranged as thin as possible, the medicine feeding branch pipe 7 passes through the top wall of the pesticide bottle 5 and is connected to the inner bottom of the pesticide bottle 5, and the top of the medicine feeding branch pipe 7 is provided with Valve; the right side of the bottom of the pressure cylinder 10 is connected with a medicine outlet pipe 15, the medicine outlet pipe 15 passes through the side wall of the mixing box 16 and communicates with the mixing box 16; the medicine inlet manifold 8 and the medicine outlet pipe 15 are provided with a single top To the valve 9, the pesticide can only be injected into the pressure cylinder 10 from the medicine inlet pipe 8 and then discharged from the medicine outlet pipe 15 without returning; the pressure cylinder 10 is provided with a piston 11, and the top of the piston 11 is fixedly connected with a piston rod 12, The piston rod 12 passes through the top wall of the pressure cylinder 10 and is slidably connected to the top wall of the pressure cylinder 10. A through hole is provided on the top of the pressure cylinder 10 to facilitate air in and out of the space of the pressure cylinder 10 above the piston 11, so as to balance the air pressure and avoid affecting the piston 11. Move up and down, the top of the piston rod 12 is fixedly connected with a pressure plate 14, a return spring 13 is arranged between the pressure plate 14 and the pressure cylinder 10, the return spring 13 is sleeved on the piston rod 12, the return spring 13 is a compression spring, and the pressure plate 14 The upward force makes the piston 11 at the top of the pressure cylinder 10; when pesticides need to be extracted, open the valve on one of the medicine feeding branch pipes 7 and press the pressure plate 14 downward to discharge the air in the pressure cylinder 10 and release it The pressure plate 14, under the action of negative pressure, the required pesticide enters the pressure cylinder 10. Press again to press the pesticide into the mixing box 16. If the pesticide needs to be replaced, close the original valve and open another branch pipe 7 The valve allows another pesticide to enter the pressure cylinder 10. Repeat pressing the pressure plate 14 to add another pesticide to the mixing box 16; since the volume of the pressure cylinder 10 remains unchanged, each time the pressure plate 14 is pressed into the mixing box 16 The amount of pesticide added remains unchanged. According to the ratio of different pesticides and the volume of the mixing box 16, the amount of each pesticide needed to be added can be easily calculated, and the pressing plate 14 corresponding to the corresponding number of times can be pressed. It is required that the error is not large and will not affect the efficacy of the drug. It is more efficient and more accurate than manual measurement or adding pesticides based on experience. It is easy to add and mix multiple pesticides in proportion;

[0023] An energy supply box 23 is fixedly arranged on the right side of the top of the base 1, and a water pump 27 is fixedly arranged on the top of the energy supply box 23. The water inlet end of the water pump 27 is connected with a water pumping pipe 26, which is connected through the side wall of the mixing box 16 To the inner bottom of the mixing tank 16; the water outlet end of the water pump 27 is connected with a water outlet pipe 28, and the right end of the water outlet pipe 28 is connected with a spray head 29; the water pump 27 is activated, and the pesticide in the mixing tank 16 can be sprayed from the spray head 29;

[0024] A second motor 30 is fixedly arranged on the top right side of the base 1, the first motor shaft at the bottom of the second motor 30 passes through the base 1 and is fixedly connected with a second rotating shaft 31, and a cutter 32 is fixedly installed at the bottom of the second rotating shaft 31, The weeds on the ground can be removed by rotating the cutter 32 to further improve the weeding effect. The removed weeds can be removed, which is convenient for later cultivation, etc.;

[0025] A storage battery 24 is fixed at the bottom of the power supply box 23, and a control circuit board 25 is fixed at the top of the power supply box 23. The control circuit board 25 is connected to the storage battery 24, the first motor 17, the water pump 27, and the second through wires. The two motors 30 are connected. A control switch 3 is provided at the handle of the push rod 2. The control switch 3 is connected to the control circuit board 25 through wires; the control switch 3 includes the control switch of the first motor 17 and the control switch of the water pump 27 The control switches of the second motor 30 and the control switches are respectively arranged at the handles of the front and rear push rods 2, making the operation more convenient.

[0026] For those skilled in the art, it is obvious that the present invention is not limited to the details of the foregoing exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
