Description

Technical Field

[0001] The invention relates to the field of pesticide application devices, in particular to a method for adjusting a spray head of a spray air cylinder with an adjustable spray head. Background Art

[0002] Pesticides refer to chemical agents used in agriculture to prevent and control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry and animal husbandry production, environmental and household hygiene pest control and epidemic prevention, industrial product mildew and moth prevention, etc. When applying pesticides in agriculture and forestry, it is necessary to use air-supply type wind tube spraying equipment to spray pesticides on farther and higher agricultural and forestry crops. When using wind tube spraying equipment, it is found that the nozzle cannot be adjusted and has poor flexibility, which easily affects the efficiency of pesticide application and the utilization rate of pesticides is low. In view of the above problems, a nozzle adjustment method of a spray wind tube with adjustable nozzle is proposed. Summary of the invention

The nozzle angle and nozzle height in the nozzle adjustment method for a spray wind tube with an adjustable nozzle are adjustable, and the nozzle has different atomization effects, is suitable for different types of agricultural and forestry crops, has high flexibility, and has a high utilization rate of pesticides.

[0004] In order to achieve the above technical objectives, the technical solution adopted by the present invention is:

[0005] A method for adjusting a nozzle of a spray gun with an adjustable nozzle, wherein the spray gun with an adjustable nozzle comprises a fan, the outside of the fan is connected to a wind gun, and a wind gun assembly is fixedly connected to the wind port of the wind gun;

[0006] The air cylinder assembly comprises an assembly housing and a medicine spraying mechanism; the medicine spraying mechanism comprises a medicine tube, a hose, a rack, a gear 1, a gear 2, a connecting rod and a nozzle; there are multiple medicine tubes, which are evenly and spacedly distributed on the end surface of the assembly housing along the circumferential direction; each medicine tube is slidably connected to the end surface of the assembly housing and the sliding direction of the medicine tube points to the center of the circle in the circumferential direction; each medicine tube is fixedly connected to a rack, the rack is meshed with a gear 1, the gear 1 is arranged on the assembly housing and can rotate under the action of an external force; each medicine tube is provided with a gear 2 and can rotate under the action of an external force, the gear 2 is connected to one end of the connecting rod, the other end of the connecting rod is connected to the hose, the outer end of the hose is connected to the nozzle, and the nozzle, the hose and the medicine tube are connected in sequence;

[0007] The nozzle adjustment method in the above-mentioned nozzle adjustable spray wind tube is as follows: under the action of external force, gear one is rotated, and gear one drives the medicine tube on the component housing to slide in the direction of the center of the circle in the circumferential direction or in the direction away from the center of the circle in the circumferential direction through the rack, thereby realizing the change of the nozzle height; under the action of external force, gear two is rotated, and gear two drives the hose to swing through the connecting rod to realize the change of the nozzle angle.

[0008] Furthermore, the medicine tube includes a pipe section 1 and a pipe section 2 which are vertically connected to each other, the pipe section 1 is slidably connected to the end face of the component shell, the pipe section 1 is fixedly connected to a rack, and the pipe section 2 is connected to a hose; a ventilation hole is provided in the middle of the component shell, and each hose and nozzle extends outward from the ventilation hole.

[0009] Furthermore, a power element 1 is connected to the component housing, the output end of which is connected to gear 1 and is used to drive gear 1 to rotate; a power element 2 is connected to each medicine tube, the output end of which is connected to gear 2 and is used to drive gear 2 to rotate.

[0010] Furthermore, the number of the medicine tube, power element 1, gear 1, rack, power element 2, gear 2, connecting rod, hose and nozzle is the same.

[0011] Furthermore, the power element 1 and the power element 2 are both motors.

[0012] Furthermore, the first tube section of the medicine tube is located inside the end face of the component shell and is slidably connected to the inner wall of the end face of the component shell, and the second tube section extends in a direction perpendicular to the end face of the component shell and is located in the ventilation hole.

[0013] Furthermore, a slide groove is arranged on the inner wall of the end face of the component shell, and the tube section 1 of the medicine tube is embedded in the slide groove and slidably connected with the slide groove. The end face of the component shell is also provided with a notch for avoiding the gear 1 and the rack.

[0014] Furthermore, the air outlet position of the wind tube is connected to the component shell of the wind tube component by welding, and wind tube brackets are connected to both ends of the wind tube.

[0015] Furthermore, each medicine tube is connected to the medicine delivery tube.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the nozzle adjustment method of the spray air cylinder with adjustable nozzle not only realizes the adjustment of the nozzle angle, but also realizes the adjustment of the nozzle height.

[0017] The nozzle can be adjusted to spray the medicine by the wind cylinder provided with a nozzle, a medicine tube, a hose, a connecting rod, a gear 1, a rack and a gear 2. When the angle of the nozzle needs to be adjusted, the gear 2 is rotated under the action of an external force, the gear 2 drives the connecting rod to rotate, and the connecting rod drives the connected hose to realize the rotation angle of the nozzle. The angle of the nozzle can be adjusted to adapt to the spraying environment of crops of different heights. The rack and the gear 1 cooperate with each other and the medicine tube is installed on one side of the rack, and the gear 1 is rotated under the action of an external force. The rack can drive the nozzle to rise and fall, so that the height of the nozzle can be adjusted. The reason for adjusting the height of the nozzle is that on the basis of the unchanged wind flow rate, adjusting the height can change the droplet flow rate and change the secondary atomization effect of the droplets to be suitable for different types of agricultural and forestry crops. The nozzle adjustment method of the present invention can make crops of different heights suitable for different nozzle angles, and different types of crops are suitable for pesticide droplets of different diameters, and the flexibility is good.

[0018] The details are as follows:

[0019] (1) In the nozzle adjustment method of the present invention, a nozzle, a medicine tube, a hose, a connecting rod and a gear 2 are provided. When the angle of the nozzle needs to be adjusted, the gear 2 drives the connecting rod to rotate under the action of an external force. One end of the connecting rod is connected to the axis of the gear 2, and the other end is connected to the hose. The connecting rod drives the hose to realize the rotation angle of the nozzle. The angle of the nozzle can be adjusted to adapt to the spraying environment of crops at different heights. Different nozzle angles match agricultural and forestry crops at different heights. Adjusting the angle of the nozzle can make the device suitable for agricultural and forestry crops at different heights, thereby increasing the flexibility of the device. When facing agricultural and forestry crops at different heights, the rotation of the gear 2 will drive the nozzle to rotate to form different nozzle angles. The different angles formed by the nozzle and the wind delivered by the fan correspond to different optimal application heights.

[0020] (2) In the nozzle adjustment method of the present invention, a medicine tube, a gear one and a rack are provided. When the height of the nozzle needs to be adjusted, the rack and the gear one cooperate with each other and the medicine tube is installed on one side of the rack. Therefore, under the action of external force, the rotation of the gear one can make the rack rise and fall, and the nozzle rises and falls together with the rack, thereby realizing the function of adjusting the height of the nozzle. The change in the height of the nozzle is equivalent to the change in the cross-sectional area of ​​the medicine outlet at the air outlet. Different cross-sectional areas result in different effects of the secondary atomization of the medicine droplets at the air outlet, thereby being suitable for the requirements of different types of agricultural and forestry crops on the size of medicine droplets, thereby increasing the types of objects for which the device can be applied.

The gear 14 is arranged on the component housing 2 and can rotate under the action of external force; when the gear 14 rotates, the gear 14 drives the medicine tube 13 on the component housing 2 to slide in the direction of the center of the circle in the circumferential direction or in the direction away from the center of the circle in the circumferential direction through the rack 12; each medicine tube 13 is provided with a gear 2 10 and can rotate under the action of external force, the gear 2 10 is connected to one end of the connecting rod 9, and the other end of the connecting rod 9 is connected to the hose 8, and the outer end of the hose 8 is connected to the nozzle 15, and the nozzle 15, the hose 8 and the medicine tube 13 are connected in sequence; when the gear 2 10 rotates, the gear 2 10 drives the hose 8 to swing through the connecting rod 9 to achieve the change of the angle of the nozzle 15.

[0030] The medicine tube 13 includes a tube section 1 and a tube section 2 which are vertically connected to each other. The tube section 1 is slidably connected to the end face of the component housing 2. The tube section 1 is fixedly connected to a rack 12. The tube section 2 is connected to a hose 8. A ventilation hole 7 is provided in the middle of the component housing 2. Each hose 8 and nozzle 15 extends outward from the ventilation hole 7.

[0031] In this embodiment, the component housing 2 is connected to a power element 1, the output end of the power element 1 is connected to a gear 14 and is used to drive the gear 14 to rotate; each medicine tube 13 is connected to a power element 2, the output end of the power element 2 is connected to a gear 2 10 and is used to drive the gear 2 10 to rotate, or the output end of the power element 2 is connected to a pinion gear, the pinion gear is meshed with the gear 2 10, the gear 2 10 is a large gear, and the pinion gear and the gear 2 10 are both rotatably connected to the medicine tube 13. When the power element 2 rotates, the gear 2 10 is driven by the pinion gear to realize the reduction transmission.

[0032] In this embodiment, the number of the medicine tube 13, the power element 1, the gear 1 14, the rack 12, the power element 2, the gear 2 10, the connecting rod 9, the hose 8 and the nozzle 15 is the same.

[0033] In this embodiment, the power element 1 and the power element 2 are both servo motors. The power element 1, the power element 2 and the fan 6 are all connected to a power supply. The power element 1, the power element 2 and the fan 6 are all connected to a controller, and the operation of the power element 1, the power element 2 and the fan 6 can be controlled by the control buttons on the controller.

[0034] In this embodiment, the first section of the medicine tube 13 is located on the inner side of the end face of the component housing 2 and is slidably connected to the inner wall of the end face of the component housing 2. The second section extends in a direction perpendicular to the end face of the component housing 2 and is located in the ventilation hole 7.

[0035] In this embodiment, Figure 4As shown, a plurality of slide grooves 16 are arranged on the inner wall of the end face of the component housing 2, and a tube section 1 of the medicine tube 13 is embedded in the slide groove 16 and slidably connected with the slide groove 16. A strip-shaped notch 11 is also opened on the end face of the component housing 2 for avoiding a gear 14 and a rack 12.

[0036] In this embodiment, the air outlet position of the wind tube 1 is connected to the component housing 2 of the wind tube component by welding, and wind tube brackets 4 are connected to both ends of the wind tube 1.

[0037] In this embodiment, each medicine tube 13 is connected to the medicine delivery tube 5. The medicine delivery tube 5 passes through the component housing 2 and is connected to the multiple medicine tubes 13. The medicine delivery tube 5 is used to deliver liquid medicine to the medicine tube 13. The power of the medicine delivery tube 5 to deliver liquid medicine adopts the existing technology. The liquid medicine enters the multiple medicine tubes 13 through the medicine delivery tube 5 and is sprayed out through the hose 8 and the nozzle 15.

[0038] This embodiment also provides a method for adjusting the nozzle of a spray gun with an adjustable nozzle, which is specifically:

[0039] When the angle of the nozzle 15 needs to be adjusted, under the action of external force (such as driven by power element 2), gear 2 10 is rotated, and gear 2 10 drives connecting rod 9 to rotate. One end of connecting rod 9 is connected to the axis of gear 2 10, and the other end is connected to hose 8. Connecting rod 9 drives hose 8 to realize the rotation angle of nozzle 15. Because different angles of nozzle 15 match agricultural and forestry crops of different heights, adjusting the angle of nozzle 15 can make the device suitable for agricultural and forestry crops of different heights, thereby increasing the flexibility of the device.

[0040] When the height of the nozzle 15 needs to be adjusted, the gear 14 in the gear rack mechanism is rotated under the action of external force (such as driven by power element 1). Since the rack 12 and the gear 14 cooperate with each other and the medicine tube 13 is installed on one side of the rack 12, the rotation of the gear 14 can drive the rack 12 to rise and fall, and the nozzle 15 rises and falls along with the rack 12 and along the slide rail 16 of the component housing 2, thereby realizing the function of adjusting the height of the nozzle 15. During the adjustment process, the nozzle 15 is always located on the inner side of the ventilation hole 7. The change in the height of the nozzle 15 is equivalent to the change in the cross-sectional area of ​​the air outlet for spraying medicine. Different cross-sectional areas result in different effects of the secondary atomization of the medicine droplets at the air outlet, thereby being suitable for the requirements of different types of agricultural and forestry crops on the size of medicine droplets, thereby increasing the types of application objects of the device.

[0041] Working principle: When this technology is in use, the medicine liquid is delivered into the medicine tube 13 inside the wind tube assembly through the medicine delivery tube 5, and then the medicine liquid is atomized for the first time in the nozzle 15 of the wind tube assembly and sprayed out from the nozzle 15; the fan 6 rotates, and the wind passes through the inner cavity of the wind tube 1, the inner cavity of the assembly shell 2 and the ventilation hole 7 of the assembly shell 2 in turn, and the medicine liquid sprayed by the nozzle 15 is transported to a distant place and realizes the second atomization function. When facing agricultural and forestry crops at different heights, the rotation of gear 2 10 will drive the nozzle 15 to rotate, forming different angles of the nozzle 15. The different angles formed by the nozzle 15 and the wind delivered by the fan 6 correspond to different optimal application heights. In the face of different types of agricultural and forestry crops, the rotation of gear 14 can drive the rise and fall of rack 12, thereby realizing the height adjustment function of nozzle 15. The change of height of nozzle 15 is equivalent to the change of cross-sectional area of ​​medicine outlet at the air outlet. Different cross-sectional areas result in different effects of secondary atomization of medicine droplets at the air outlet, so that it can be adapted to the requirements of different types of agricultural and forestry crops for the size of medicine droplets, increasing the types of objects for which the device can be applied.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
