Description

Technical Field

[0001] This utility model relates to the field of fruit planting technology, and more specifically, it relates to a spraying device for controlling pests and diseases in fruit planting. Background Technology

[0002] In fruit cultivation, pests and diseases are the main threats to yield and quality. Pests and diseases such as aphids, spider mites, and downy mildew can eat branches and leaves and damage fruits. If they are not controlled in time, they can lead to a significant reduction in yield. In the early days, fruit farmers mostly relied on manual spraying with simple sprayers on their backs. This not only required frequent bending and lifting of arms, which was labor-intensive, but also resulted in uneven spraying—the top of the plant and the back of the leaves were difficult to spray, leading to residual pests and diseases and their recurrence.

[0003] In existing technologies, fruit trees have differences in height and the inner and outer layers of branches and leaves. Traditional spraying devices have fixed or adjustable connecting rods, making it difficult to cover different locations and easily creating blind spots in pest control. Different parts of the fruit tree (such as young leaves and fruits) or different pests and diseases require different spray flow rates. A fixed flow rate can easily lead to waste of pesticide or insufficient coverage. Traditional adjustment methods have low precision. Different types of nozzles need to be replaced for different fruit trees or pests and diseases. Traditional nozzles are mostly connected by threads, which is time-consuming to disassemble and install, and are prone to jamming due to pesticide corrosion, affecting the progress of pest control.

An adjusting rod 10 is rotatably mounted inside the connecting pipe 2, and an adjusting plate 11 is provided on the adjusting rod 10. The adjusting spring 8 is located between the adjusting springs in the connecting pipe 2. The device includes a fixing block 12, a mounting tube 13 on the nozzle 5, a snap-fit ​​rod 14 on the connecting rod 4, a snap-fit ​​hole 15 on the mounting tube 13 that mates with the snap-fit ​​rod 14, a snap-fit ​​groove 16 on the connecting rod 4, a snap-fit ​​plate 17 within the snap-fit ​​groove 16 on the snap-fit ​​rod 14, a snap-fit ​​spring 18 between the snap-fit ​​groove 16 and the snap-fit ​​plate 17, a sliding block 19 on the mounting tube 13, a sliding groove 20 on the connecting rod 4 that mates with the sliding block 19, a fixing ring 21 on the connecting rod 4, and a fixing spring 22 and a fixing sleeve 23 on one side of the fixing ring 21.

[0022] In this embodiment, during use, the nozzle 5 is mounted on the connecting rod 4. The fixing sleeve 23 compresses the fixing spring 22, causing the locking rod 14 to move outwards under the elastic force of the locking spring 18. Through the cooperation of the sliding block 19 and the sliding groove 20, the mounting tube 13 is positioned and mounted on the connecting rod 4. Then, the fixing sleeve 23 is released, and it resets under the elastic force of the fixing spring 22. One side of the fixing sleeve 23 has a tapered curved surface. The clamping rod 14 is pressed, causing the clamping plate 17 to press against the clamping spring 18. At the same time, the clamping rod 14 moves inward around the circumference. The clamping rod 14 cooperates with the clamping hole 15 to facilitate the installation and fixing of the installation pipe 13 and the nozzle 5. A water pump is installed in the medicine tank 1 to facilitate the delivery of pesticides for pests and diseases in the medicine tank 1 through the connecting pipe 2 and the connecting pipe 2, and spray them out through the nozzle 5. The fruit farmer holds the handle 3 and adjusts the connecting rod 4 to facilitate the treatment of pests and diseases on the fruit trees.

[0023] Please see Figures 4-5 As one embodiment of the flow rate regulation device: the connecting pipe 2 is provided with an adjustment handle 24, the adjustment handle 24 is provided with an adjustment gear ring 25, the adjustment rod 10 is provided with an adjustment gear 26, the bottom of the adjustment handle 24 is provided with a limiting tooth 27 axially, the connecting pipe 2 is provided with a limiting plate 28, the limiting plate 28 is provided with a limiting spring 29 and a limiting disc 30, the limiting disc 30 is engaged with the limiting tooth 27, the connecting pipe 2 is provided with a limiting track 31, the limiting disc 30 is slidably disposed on the limiting track 31, the connecting pipe 2 is fixedly provided with a moving track 32, and the moving plate 7 is slidably disposed on the moving track 32.

[0024] More specifically, when adjusting the flow rate of nozzle 5, the limiting plate 30 is pulled along the limiting track 31, causing the limiting plate 30 to disengage from the limiting tooth 27 and compress the limiting spring 29. Then, the adjusting handle 24 is rotated, which drives the adjusting gear ring 25 to rotate. The adjusting gear ring 25 drives the adjusting gear 26 and the adjusting rod 10 to rotate. When the adjusting rod 10 rotates, it drives the adjusting plate 11 to rotate. The adjusting plate 11 presses the adjusting block 9 and the adjusting spring 8. The moving plate 7 slides on the moving track 32, thereby adjusting the bending and extension angle of the adjusting spring 8. In conjunction with the fixing block 12, the cross-sectional area of ​​the water flow at the adjusting spring 8 is adjusted. When the cross-sectional area of ​​the water flow decreases, the flow rate of the water increases according to Bernoulli's principle. When the cross-sectional area of ​​the water flow increases, the flow rate of the water flow decreases according to Bernoulli's principle, which facilitates the adjustment of the pesticide spraying flow rate.

[0025] In summary, during use or operation of the overall equipment: When in use, the nozzle 5 is installed on the connecting rod 4. The fixing sleeve 23 compresses the fixing spring 22, causing the locking rod 14 to move outwards under the elastic force of the locking spring 18. Through the cooperation of the sliding block 19 and the sliding groove 20, the mounting tube 13 is positioned and installed on the connecting rod 4. Then, the fixing sleeve 23 is released, and it resets under the elastic force of the fixing spring 22. One side of the fixing sleeve 23 has a tapered curved surface... The conical curved surface presses against the clamping rod 14, causing the clamping rod 14 to drive the clamping plate 17 to press against the clamping spring 18. At the same time, the clamping rod 14 moves inward to the circumference. Through the cooperation between the clamping rod 14 and the clamping hole 15, it is convenient to install and fix the position of the installation pipe 13 and the nozzle 5. A water pump is installed in the medicine tank 1 to facilitate the delivery of pesticides for pests and diseases in the medicine tank 1 through the connecting pipe 2 and the connecting pipe 2, and spray them out through the nozzle 5. The fruit farmer holds the handle 3 and adjusts the connecting rod 4 to facilitate the treatment of pests and diseases on the fruit trees.

[0026] When adjusting the flow rate of nozzle 5, pull the limiting plate 30 along the limiting track 31, causing the limiting plate 30 to move away from the limiting tooth 27 and compress the limiting spring 29. Then rotate the adjusting handle 24, which drives the adjusting gear ring 25 to rotate. The adjusting gear ring 25 drives the adjusting gear 26 and the adjusting rod 10 to rotate. When the adjusting rod 10 rotates, it drives the adjusting plate 11 to rotate. The adjusting plate 11 presses the adjusting block 9 and the adjusting spring 8. The moving plate 7 slides on the moving track 32, thereby adjusting the bending and extension angle of the adjusting spring 8. In conjunction with the fixing block 12, the cross-sectional area of ​​the water flow at the adjusting spring 8 is adjusted. When the cross-sectional area of ​​the water flow decreases, the flow rate of the water increases according to Bernoulli's principle. When the cross-sectional area of ​​the water flow increases, the flow rate of the water flow decreases according to Bernoulli's principle, which facilitates the adjustment of the pesticide spraying flow rate.
