[0015] Compared with the prior art, the present invention provides a fertilizer applicator nozzle adjustment device, which has the following beneficial effects:

[0016] 1. Through the arrangement of the adjusting cylinder, inner cylinder, mounting cylinder, holding sleeve, filter plate, filter holes, inner cavity, water inlet, water outlet, blocking plate, first sliding groove, and first insert, the adjusting cylinder is slidably connected to the inner cylinder via the first insert. When the adjusting cylinder slides, it drives the internal blocking plate to move. The blocking plate is embedded in the inner cylinder. In this way, the number of exposed water inlets can be precisely adjusted. Therefore, according to the different crop growth needs, soil fertility conditions, and other factors, the amount of fertilizer solution entering the nozzle can be flexibly and accurately controlled to achieve precision fertilization, improve fertilizer utilization efficiency, and avoid fertilizer waste. The filter plate and array of filter holes at the bottom of the inner cylinder can effectively intercept impurities before the fertilizer solution enters the inner cavity, preventing impurities from entering the nozzle, avoiding nozzle clogging, greatly extending the service life of the nozzle, ensuring stable and continuous operation of the nozzle, and improving the stability and reliability of fertilization operations. The regulating cylinder and the inner cylinder are slidably connected through the cooperation of the first insert and the first sliding groove. This structure is not only stable but also easy to operate, making the process of adjusting the amount of fertilizer smoother, reducing the labor intensity of operators, and improving the efficiency of fertilization operations.

[0017] 2. Through the design of the second slide groove, the second insert, and the grip sleeve, the grip sleeve is slidably connected to the adjusting cylinder via the second insert. The arc-shaped structure of the second insert and the second slide groove ensures that the grip sleeve can slide smoothly along the adjusting cylinder. The operator can easily push or pull the grip sleeve, thereby causing the adjusting cylinder to slide and adjusting the fertilizer application rate. The operation process is simple and smooth, greatly improving the convenience and efficiency of adjustment. The rubber sleeve wrapped around the outside of the grip sleeve increases the operator's comfort when holding it, reduces hand fatigue that may be caused by prolonged operation, and also ensures sufficient friction between the hand and the grip sleeve to prevent the grip sleeve from accidentally slipping during operation, ensuring the accuracy and safety of operation. The second insert and the second slide groove arranged in a ring array make the connection between the grip sleeve and the adjusting cylinder more stable. During frequent operation, it can effectively withstand external forces and is not prone to loosening or disengagement, ensuring the stability of the entire adjusting device structure and facilitating the long-term stable function of adjusting the fertilizer application rate.

[0025] 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.

[0026] In this embodiment, the specific implementation steps of a fertilizer applicator nozzle adjustment device are as follows: The main body 1 of the adjustment device is threadedly connected to the fertilizer applicator through the threaded groove 20 on the outer side of the mounting cylinder 5, ensuring a tight connection between the two and preventing loosening that could affect fertilization operations. The sliding connection between the adjustment cylinder 3 and the inner cylinder 4 via the first insert 12 and the first sliding groove 7 is checked for smoothness. The sliding connection between the gripping sleeve 2 and the adjustment cylinder 3 via the second insert 6 and the second sliding groove 13 is also checked for normality. The rubber sleeve is also inspected for damage. Check the filter holes 18 on the filter plate 15 for blockage. When adjusting the fertilizer application rate, the operator holds the grip sleeve 2. Since the grip sleeve 2 is slidably connected to the adjusting sleeve 3 through the second insert 6, the grip sleeve 2 can be pushed or pulled according to the actual fertilizer application requirements, thereby causing the adjusting sleeve 3 to slide on the inner sleeve 4. When the adjusting sleeve 3 slides, the blocking plate 10 at the bottom inside moves accordingly. The blocking plate 10 is embedded in the inner sleeve 4. The number of water inlet holes 16 exposed by the linear array opened on the lower inner side of the inner sleeve 4 is adjusted by the movement of the blocking plate 10. If the amount of fertilizer needs to be increased, more water inlet holes 16 are exposed; if the amount of fertilizer needs to be reduced, the number of water inlet holes 16 exposed is reduced. When the fertilizer applicator is working, the fertilizer solution enters the inner cylinder 4 through the fertilizer inlet chamber 19 located in the middle of the mounting cylinder 5. The fertilizer solution first passes through the filter plate 15 located at the bottom of the inner cylinder 4. The filter holes 18 arranged in an array on the filter plate 15 filter out impurities in the fertilizer solution. The filtered fertilizer solution enters the inner cavity 14 of the inner cylinder 4 and flows in through the water inlet holes 16 exposed at the bottom inside the inner cavity 14. The water flows out from the outlet hole 17 on the upper inner side of the inner cavity 14 and is finally sprayed evenly into the farmland through the spray holes 9 arranged in a ring array inside the nozzle 8. After the fertilization operation is completed, the main body 1 of the adjustment device is removed from the fertilizer applicator by rotating the mounting cylinder 5 and taking advantage of the threaded connection. The adjustment device is then cleaned, and components such as the inner cylinder 4 can be removed. Impurities remaining on the filter plate 15 are cleaned to ensure that the filter holes 18 are unobstructed. At the same time, each component is checked for damage. If any damage is found, it is replaced or repaired in time for future use.

[0027] like Figure 1-6As shown, an inner cylinder 4 is provided inside the regulating cylinder 3, an installation cylinder 5 is provided at the rear side of the inner cylinder 4, a gripping protective cylinder 2 is provided at the outer side of the regulating cylinder 3, a filter plate 15 is provided at the bottom inside the inner cylinder 4, filter holes 18 are arranged in an array inside the filter plate 15, an inner cavity 14 is provided at the inner side of the inner cylinder 4, water inlet holes 16 are linearly arranged at the lower inner side of the inner cavity 14, and water outlet holes 17 are arranged at the upper inner side of the inner cavity 14. A blocking plate 10 is provided at the lower inner side of the regulating cylinder 3, and the blocking plate 10 is fixedly connected to the regulating cylinder 3 through a connecting rod 11. The blocking plate 10 is embedded in the inner cylinder 4. A first sliding groove 7 is arranged in an annular array on the outer side of the inner cylinder 4. A first insert 12 is arranged in an annular array at the bottom inner side of the regulating cylinder 3. The regulating cylinder 3 is slidably connected to the inner cylinder 4 through the first insert 12. The number of water inlet holes 16 exposed is adjusted by the sliding of the regulating cylinder 3 and the internal blocking plate 10.

[0028] Preferably, the regulating cylinder 3 is slidably connected to the inner cylinder 4 via the first insert 12. When the regulating cylinder 3 slides, it drives the internal blocking plate 10 to move. The blocking plate 10 is embedded in the inner cylinder 4. In this way, the number of exposed water inlet holes 16 can be precisely adjusted. Thus, the amount of fertilizer solution entering the nozzle can be flexibly and accurately controlled according to the different crop growth needs, soil fertility conditions, and other factors, achieving precise fertilization, improving fertilizer utilization efficiency, and avoiding fertilizer waste. The filter plate 15 and the array of filter holes 18 set at the bottom of the inner cylinder 4 can effectively intercept impurities in the fertilizer solution before it enters the inner cavity 14, preventing impurities from entering the nozzle, avoiding nozzle hole blockage, greatly extending the service life of the nozzle, ensuring stable and continuous operation of the nozzle, and improving the stability and reliability of fertilization operations. The regulating cylinder 3 and the inner cylinder 4 are slidably connected by the cooperation of the first insert 12 and the first sliding groove 7. This structure is not only stable in connection but also convenient in operation, making the process of adjusting the amount of fertilizer smoother, reducing the labor intensity of operators, and improving the efficiency of fertilization operations.

[0029] like Figure 1-2 and Figure 4-6 As shown, a second sliding groove 13 is provided in an annular array at the outer side of the adjusting cylinder 3, and a second insert 6 is provided in an annular array at the top of the inner side of the gripping sleeve 2. The second insert 6 and the second sliding groove 13 are corresponding arc-shaped structures. The gripping sleeve 2 is slidably connected to the adjusting cylinder 3 through the second insert 6, and a rubber sleeve is provided on the outer side of the gripping sleeve 2.

[0030] Preferably, the gripping sleeve 2 is slidably connected to the adjusting sleeve 3 via the second insert 6. The arc-shaped structure of the second insert 6 and the second sliding groove 13 ensures that the gripping sleeve 2 can slide smoothly along the adjusting sleeve 3. The operator can easily push or pull the gripping sleeve 2 by holding it, thereby causing the adjusting sleeve 3 to slide and adjust the fertilizer application rate. The operation process is simple and smooth, greatly improving the convenience and efficiency of adjustment. The rubber sleeve wrapped around the outside of the gripping sleeve 2 increases the operator's comfort when holding it, reduces hand fatigue that may be caused by long-term operation, and also ensures sufficient friction between the hand and the gripping sleeve 2 to prevent the gripping sleeve 2 from accidentally slipping during operation, ensuring the accuracy and safety of operation. The second insert 6 and the second sliding groove 13 arranged in a ring array make the connection between the gripping sleeve 2 and the adjusting sleeve 3 more stable. During frequent operation, it can effectively withstand external forces and is not prone to loosening or disengagement, ensuring the stability of the entire adjusting device structure and facilitating the long-term stable function of adjusting the fertilizer application rate.

[0031] like Figure 2 and Figure 4-5 As shown, a fertilizer inlet chamber 19 is provided in the middle of the installation cylinder 5, and a threaded groove 20 is provided on the outer side of the installation cylinder 5. The main body 1 of the adjustment device is threadedly connected to the fertilizer applicator through the installation cylinder 5.

[0032] Optionally, the threaded groove 20 on the outer side of the mounting cylinder 5 allows the main body 1 of the adjusting device to be threadedly connected to the fertilizer applicator via the mounting cylinder 5. This connection method is simple to operate; simply screw the threaded groove 20 on the mounting cylinder 5 to the corresponding threaded part of the fertilizer applicator to quickly complete the connection and disassembly. The fertilizer inlet chamber 19 located in the middle of the mounting cylinder 5 provides ample flow space for the fertilizer solution. The fertilizer solution can smoothly enter the adjusting device through the fertilizer inlet chamber 19 for subsequent processing and adjustment, avoiding the problem of poor fertilizer inlet caused by narrow or blocked channels, and ensuring the smooth operation of the entire fertilization system.
