DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A crop spraying device comprises a cart 21 and a spraying assembly mounted on the cart, the spraying assembly comprises a manual air pump 22 and a spraying water tank 5 connected to the manual air pump 22, the spraying water tank 5 is provided with a cover which can be opened and closed in a sealed manner, the spraying water tank 5 is connected to the spraying assembly through a water pipe 3, the manual air pump 22 comprises an air pumping push rod 12 which can perform piston motion, the free end of the air pumping push rod 12 is rotatably connected to a connecting rod 13, the cart has at least one wheel 19, the wheel 19 is eccentrically fixed with an eccentric shaft 14, and the eccentric shaft 14 is rotatably connected to an end of the connecting rod 13 away from the air pumping push rod 12.

[0021] When the device is used to spray crops, the prepared medicine is put into the spray water tank 5, and the cart 21 is pushed to move in the field. When the wheel 19 rotates, the eccentric shaft 14 is driven to make a circular motion, and the connecting rod 13 is driven to move through the eccentric shaft 14. The connecting rod 13 pushes and pulls the air pump push rod 12 of the manual air pump to achieve the air pumping action. The manual air pump is used to pump air into the spray water tank 5, so that the medicine in the spray water tank 5 becomes pressurized water. The pressurized medicine is sprayed outwardly through the water pipe 3 and the spray assembly as medicine mist to complete the spraying action. The device does not require farmers to carry a spray barrel for spraying medicine, which reduces the weight of farmers when spraying medicine. Farmers only need to push the cart 21 to walk in the field to complete the spraying action. It is simple and convenient to use.

[0022] As an implementation method, refer to Figure 1 The manual air pump 22 includes an air pump housing 10 fixed to the trolley 21, a piston 11 installed in the air pump housing 10, an air cavity 9 between the piston 11 and the air pump housing 10, and the air pump housing 10 is provided with a one-way air inlet valve 8 and a one-way air outlet valve 7 which can connect the outside with the air cavity 9. The outlet part of the one-way air outlet valve 7 is connected with the spray water tank 5 through the air pipe 6. The air pump push rod 12 is fixedly assembled with the piston 11. When the connecting rod 13 pulls the air pump push rod 12 downward, the air cavity 9 gradually becomes larger, and the outside gas enters the air cavity 9 through the one-way air inlet valve 8. When the connecting rod 13 pushes the air pump push rod 12 upward, the air cavity 9 gradually becomes smaller, and the gas in the air cavity 9 enters the spray water tank 5 through the one-way air outlet valve 7, thereby increasing the pressure in the spray water tank 5.

[0023] Since the wheels 19 of the cart 21 need to keep moving when spraying pesticides, the manual air pump 22 will keep inflating the spray water tank 5. In order to avoid excessive pressure in the spray water tank 5, a gas pressure relief valve 4 is installed on the top of the spray water tank 5. When the pressure exceeds the pressure relief pressure of the gas pressure relief valve 4, the gas in the spray water tank 5 will be discharged from the gas pressure relief valve 4.

[0024] refer to Figure 3 There are at least two spray water tanks 5, and the upper parts of the multiple spray water tanks 5 are connected by connecting air pipes 23, and the multiple spray water tanks 5 are pressurized by manual air pumps 22. Of course, the multiple spray water tanks 5 can be loaded with different agents or the same agents, which can be set according to needs.

[0025] As an implementation manner, the cart 21 is a hand-pushed wheelbarrow.

[0026] refer to Figure 1The cart 21 includes a support platform 16, a bracket 15 fixedly connected to the support platform 16, an end of the bracket 15 rotatably connected to a support shaft 20, the support shaft 20 is fixedly connected to a wheel 19, the bracket 15 is located on one side of the wheel 19, and the eccentric shaft 14 is arranged on the side of the wheel 19 away from the bracket 15. The bracket is installed on one side and the eccentric shaft is installed on the other side to avoid mechanical interference when the connecting rod 13 moves.

[0027] Furthermore, a handlebar 1 and a support leg 17 are installed on a side of the support platform 16 away from the wheel 19 .

[0028] As an embodiment of the spray assembly, the spray assembly includes a spray pipe 2, which is installed on a cart 21. The spray pipe 2 is connected to a water pipe 3. The spray pipe 2 is equipped with a plurality of water mist nozzles 18. The pressurized liquid medicine enters the spray pipe 2 through the water pipe 3 and is dispersed to the plurality of water mist nozzles 18 through the spray pipe 2. This type of spray assembly can use existing technology.

[0029] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
