Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spacing-adjustable corn planting spraying device. Background Art

[0002] Corn is the most widely distributed crop in the world, and is a staple food in parts of my country. During the initial planting phase, corn requires the use of various pesticides to prevent diseases like brown leaf spot. Even after the corn has grown, farmers must constantly monitor the condition of their fields and spray pesticides promptly to prevent and control pests. When spraying small farmlands, farmers often carry spray tanks on their backs and conduct the spraying themselves.

[0003] For example, a corn planting spraying device with the publication (announcement) number CN220987348U relates to the field of corn planting technology, including a handle and a medicine box, the outer surface of the handle is fixedly installed with a side fixing plate, the outer surface of the handle is provided with a toggle mechanism, the toggle mechanism includes a bevel gear disc and a rotating handle, the inner wall of the bevel gear disc is rotatably connected to the outer surface of the handle, the outer surface of the bevel gear disc is meshed with a bevel gear, one end of the bevel gear is rotatably connected to the inner wall of the side fixing plate, and one end of the rotating handle passes through one end of the side fixing plate and is fixedly installed with one end of the bevel gear. In the utility model, when spraying pesticides, farmers can rotate the rotating handle and use the handle, the bevel gear disc and the number one telescopic rod to toggle the upper leaves of the corn plant, so that the corn stalks are exposed to be sprayed with pesticides, and a large area of ​​leaves can be toggled at one time, thereby improving the effect of corn disease and insect pest control.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that when spraying pesticides, the above device needs to rely on farmers to hold the handle and swing the water pipe to cover the corn with pesticides. This traditional spraying method can easily lead to uneven distribution of pesticides, with some areas being over-sprayed and other areas being under-sprayed, affecting crop health and pesticide effectiveness. At the same time, farmers have a high labor intensity while swinging the water pipe.

[0005] Therefore, in order to solve the above problems, a spacing-adjustable corn planting spraying device is proposed. Utility Model Content

[0028] Reference Figure 3 and Figure 4 The water pipe quick connector 11 is used to connect the liquid guide tube 25 to the nozzle 10, thereby forming a complete water path. The slider 12 is used to cooperate with the first chute 5 and the second chute 6 to achieve the purpose of synchronously moving multiple nozzles 10 by the control panel 4, which lowers the threshold for farmers to use. The control panel 4 is easily limited by the abutment plate 13 to prevent the control panel 4 from separating from the surface of the limit block 3 during movement.

[0029] A through slot 14 is provided in the middle of the top of the control board 4 , a through hole 15 is provided on the inner wall of one side of the through slot 14 , and limiting slots 16 are provided on both sides of the top of the control board 4 .

[0030] Reference Figure 3 The through groove 14 facilitates the provision of space for the threaded rod 18 to move, the through hole 15 facilitates the provision of space for the threaded rod 18 to be inserted into the internal space of the control board 4, and the limiting groove 16 facilitates the provision of space for the control board 4 to move, thereby achieving the purpose of the control board 4 adjusting the spacing between the nozzles 10.

[0031] A support base 17 is fixedly installed in the middle part of the top of the U-shaped base plate 1, and a threaded rod 18 is threadedly connected to the middle part of the back of the support base 17. A driving handle 19 is fixedly installed at one end of the threaded rod 18, and a plurality of nuts 20 are movably installed on the surface of the other end of the threaded rod 18.

[0032] Reference Figure 2 The through groove 14 facilitates the provision of space for the threaded rod 18 to move, the through hole 15 facilitates the provision of space for the threaded rod 18 to be inserted into the internal space of the control board 4, and the limiting groove 16 facilitates the provision of space for the control board 4 to move, thereby achieving the purpose of the control board 4 adjusting the spacing between the nozzles 10.

[0033] A placement rack 21 is fixedly mounted in the middle of the bottom of the U-shaped base plate 1 , a liquid medicine box 22 is movably mounted inside the placement rack 21 , and a drainage pipe 23 is fixedly mounted on one side of the top of the liquid medicine box 22 .

[0034] Reference Figure 1 and Figure 2 The through groove 14 facilitates the provision of space for the threaded rod 18 to move, the through hole 15 facilitates the provision of space for the threaded rod 18 to be inserted into the internal space of the control board 4, and the limiting groove 16 facilitates the provision of space for the control board 4 to move, thereby achieving the purpose of the control board 4 adjusting the spacing between the nozzles 10.

[0035] A diversion pipe 24 is fixedly mounted on one end of the drainage pipe 23 , a liquid guide pipe 25 is fixedly mounted on one side of the surface of the diversion pipe 24 , and one end of the liquid guide pipe 25 is embedded in the water pipe quick connector 11 .

[0036] Reference Figure 1 and Figure 2 The pressurized liquid medicine can be diverted through the diversion tube 24 and the liquid guide tube 25 to ensure that the nozzle 10 sprays the liquid medicine evenly.

[0038] Reference Figure 1 The shoulder strap 26 is used to facilitate farmers to move the entire device, thereby completing the overall spraying of corn.

[0039] Working principle: When using this device, the threaded rod 18 is rotated by driving the handle 19, and the control board 4 is moved by the rotation of the threaded rod 18. As the control board 4 moves, the first chute 5 and the second chute 6 generate thrust on the slider 12, and the slider 12 drives the spray head 10 to move synchronously through the connecting column 8 and the connecting plate 9. During this period, the connecting column 8 is limited by the cross bar 7. At this time, the spray head 10 can only move laterally. As the spray head 10 moves laterally, the spacing between the spray heads 10 increases or decreases. When the spacing between the spray heads 10 is adjusted to be equal to the corn row spacing, the threaded rod 18 is stopped and the debugging is completed. The entire device is fixed to the farmer's back through the shoulder strap 26. After the liquid medicine is pressurized by the submersible pump inside the liquid medicine tank 22, the liquid medicine is released to the shunt pipe 24 through the drain pipe 23. The liquid medicine is released to the spray head 10 through the shunt pipe 24 and the liquid guide pipe 25. The liquid medicine is atomized and sprayed onto the surface of the corn through the spray head 10, and the device moves as the farmer drives it to complete the entire spraying process.
