Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an adjustable height under-leaf sprayer. Background Technology

[0002] Corn is one of the world's most important food crops. As a food, corn can be cooked directly or processed into cornmeal, corn grits, etc. It can also be used to make traditional foods such as cornbread and corn cakes. As feed, its kernels and straw have become core raw materials for animal husbandry due to their high protein and high energy characteristics. In the process of corn planting and growth, in order to ensure that corn seedlings can grow healthily and obtain sufficient nutrients, light and growing space, it is necessary to use a sprayer to remove the weeds growing next to them.

[0003] The existing sprayer has a nozzle installed on a pipe, which is placed directly under the corn seedlings. The nozzle sprays pesticides on weeds. Because the position of the nozzle is fixed, while the height of the weeds and corn seedlings changes as they grow, the pesticide sprayed from the nozzle may hit the heart of the corn seedlings, causing pesticide damage and adversely affecting the growth of the corn seedlings.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1 to 4 As shown, an adjustable-height under-leaf sprayer includes:

[0031] Infusion tube 1;

[0032] Multiple adapters 2 are distributed along the length of the drug delivery tube 1;

[0033] Multiple telescopic mechanisms 3, each telescopic mechanism 3 includes a retractable shaft 34, a suspension tube 35, and a drive assembly 36. The suspension tube 35 is spirally wound on the outer surface of the retractable shaft 34, and an adapter 2 is connected to the top end of the suspension tube 35. The drive assembly 36 is installed at one end of the retractable shaft 34.

[0034] The adapter 2 is internally connected to the drug delivery tube 1 and the suspension tube 35;

[0035] Two diversion pipes 4 are installed on the lower part of the outer surface of each of the multiple telescopic mechanisms 3. An adjustment mechanism 5 is installed on the lower part of the outer surface of each of the multiple telescopic mechanisms 3 and the lower part of the outer surface of each diversion pipe 4. An atomizing nozzle 6 is installed at the bottom of each of the multiple adjustment mechanisms 5.

[0036] Depend on Figures 1 to 3 It can be seen that mounting brackets 7 are installed on the lower part of the outer surface of multiple hanging pipes 35, weed detectors 8 are installed on the outer wall of multiple mounting brackets 7, protective covers 9 are installed in the middle of the outer wall of multiple telescopic mechanisms 3, and controllers 10 are installed on the lower part of the outer wall of multiple telescopic mechanisms 3.

[0037] The telescopic mechanism 3 also includes a telescopic box 31, a mounting hole 32, and an inlet / outlet hole 33. The mounting hole 32 is located at the top of the telescopic box 31, and the telescopic box 31 is mounted on the outer surface of the adapter 2 through the mounting hole 32. The inlet / outlet hole 33 is located at the bottom of the telescopic box 31, and the retracting shaft 34 is mounted between the inner walls of both sides of the telescopic box 31 through bearings.

[0038] As can be seen from the above, firstly, the weed detector 8 can identify whether there are weeds around the corn plants and transmit the signal to the controller 10. If weeds are detected, the controller 10 controls the atomizing nozzle 6 to spray pesticide solution. The pesticide solution is precisely sprayed onto the soil and weeds around the corn roots and stems through the adjustment mechanism 5. If no weeds are detected, the controller 10 controls the atomizing nozzle 6 to turn off to avoid pesticide waste. In the corn planting environment, since the height of the corn plants changes continuously with the growth stage, the telescopic mechanism 3 can precisely adjust the suspension pipe 35 according to the actual growth height of the corn. The retraction and extension mechanism is activated by the drive component 36, which rotates the retraction and extension shaft 34 within the telescopic box 31. The rotation of the retraction and extension shaft 34 causes the suspension tube 35 to retract and extend, thereby adjusting the height of the adjustment mechanism 5 connected to the suspension tube 35 and the atomizing nozzle 6. This allows the atomizing nozzle 6 to be lowered to the lower part of the corn plant leaves, enabling the pesticide to be accurately sprayed onto the soil and weeds around the corn rootstock. This effectively avoids the problem of pesticide damage caused by spraying pesticides onto the corn seedling heart due to the fixed height of traditional sprayers, providing a good environment for the healthy growth of corn seedlings and ensuring the yield and quality of corn.

[0039] For details, please refer to Figures 1 to 3As shown, the drive assembly 36, the weed detector 8, and the atomizing nozzle 6 are all electrically connected to the controller 10, and the drive assembly 36 and the controller 10 are both located inside the protective cover 9. The suspension pipe 35 is set as an HDPE double-wall corrugated pipe.

[0040] As can be seen from the above, the drive assembly 36, the weed detector 8, and the atomizing nozzle 6 can work together under the command of the controller 10. After the weed detector 8 detects weeds, it transmits the signal to the controller 10 through electrical connection. The controller 10 then controls the drive assembly 36 and the atomizing nozzle 6 to perform corresponding actions according to the signal. The protective cover 9 plays an important role in protecting the drive assembly 36 and the controller 10. It is set as an HDPE double-wall corrugated pipe suspension pipe 35, which can be frequently wound or unwound without affecting the stable water supply requirements.

[0041] Example 2:

[0042] refer to Figure 4 As shown, the adjustment mechanism 5 includes an adjustment cylinder 51, a connector 52, a guide hole 53, and a universal ball 54. The connector 52 is installed at the top of the adjustment cylinder 51 and is threaded onto the lower part of the outer surface of the suspension pipe 35. The guide hole 53 is opened between the inner wall of the adjustment cylinder 51 and the connector 52. The universal ball 54 is embedded in the lower side of the inner wall of the adjustment cylinder 51.

[0043] A sealing ring 55 is installed at the connection between the adjusting cylinder 51 and the universal ball 54. An installation groove 56 is provided in the middle of the bottom end of the universal ball 54, and the installation groove 56 is threadedly connected to the atomizing nozzle 6. A flow hole 57 is provided in the middle of the top groove wall of the installation groove 56.

[0044] As can be seen from the above, firstly, the connector 52 is threaded onto the lower part of the outer surface of the suspension pipe 35 or the lower part of the outer surface of the diversion pipe 4. The pesticide solution flows into the suspension pipe 35 from the delivery pipe 1, and then enters the regulating cylinder 51 through the guide hole 53. Since a sealing ring 55 is installed at the connection between the regulating cylinder 51 and the universal ball 54, the sealing of the connection can be enhanced, ensuring that the pesticide solution will not leak from the connection and ensuring the stable operation of the spraying system. The pesticide solution then flows into the atomizing nozzle 6 through the flow hole 57, and finally the atomizing nozzle 6 atomizes and sprays the pesticide solution. At this time, with the flexible rotation characteristics of the universal ball 54, the direction of the atomizing nozzle 6 can be freely adjusted, so that the atomizing nozzle 6 can spray the pesticide precisely from multiple angles according to the actual position of the weeds, so that the pesticide solution is accurately sprayed on the soil and weeds around the corn roots and stems, improving the spraying effect and reducing pesticide waste. Moreover, the adjustment mechanism 5, in conjunction with the telescopic mechanism 3, further improves the accuracy and efficiency of spraying, effectively saves pesticide resources, and reduces agricultural production costs.

[0045] Preferred, Reference Figure 4As shown, spiral grooves are provided on the inner walls of both the mounting groove 56 and the connector 52, and the adjusting cylinder 51 and the connector 52 are designed as an integrated structure.

[0046] As can be seen from the above, the spiral groove is beneficial to the connection between the mounting groove 56 and the atomizing nozzle 6, and the spiral groove is also beneficial to the connection between the connector 52 and the suspension pipe 35. The integrated structure between the adjusting cylinder 51 and the connector 52 can enhance the strength and stability of the entire adjusting mechanism 5, making it less prone to damage when subjected to external forces or when performing adjustment operations.

[0047] Application example:

[0048] This design is applied to corn-growing environments, such as large-scale corn farms, where corn plants are densely packed, vary in height at different growth stages, and weeds grow in complex conditions. Weeds compete with corn seedlings for nutrients, light, and growing space. Traditional sprayers are difficult to use accurately and can easily damage corn seedlings. The principle of this design is as follows: In the telescopic mechanism 3, the suspension tube 35 is spirally wound on the retracting shaft 34. The drive component 36 drives the retracting shaft 34 to rotate, thereby retracting or extending the suspension tube 35 and adjusting the nozzle height to the lower part of the corn plant leaves. In the adjustment mechanism 5, the direction of the atomizing nozzle 6 can be flexibly adjusted via the universal ball 54. Furthermore, the weed detector 8 is electrically connected to the controller 10, which can identify weeds and automatically shut off the atomizing nozzle 6 when there are no weeds. In this environment, the effect is significant, enabling accurate spraying, avoiding spraying pesticides into the heart of the corn seedlings, reducing pesticide damage, and benefiting corn seedling growth. It can also improve spraying efficiency, save pesticides, reduce manual operation time and labor intensity, and adapt to corn at different growth stages, ensuring accurate spraying throughout the entire growth cycle.
