[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a telescopic and adjustable spraying rod, including: a spraying tube 1, a fixed tube 2, a movable tube 3 and a tube storage mechanism 4. The spraying tube 1 is fixedly installed in the inner cavity of the fixed tube 2, and one end of the spraying tube 1 extends out of the fixed tube 2 to form a spraying end. The fixed tube 2 is slidably installed in the movable tube 3. The outer wall of the fixed tube 2 is provided with a tube storage mechanism 4, which is used to wrap and store the spraying tube 1 that extends out of the fixed tube 2 on the surface of the fixed tube 2 when not spraying.

[0026] The medicine tube storage mechanism 4 includes a storage rack 41, a limiting plate 42, protrusions 43 and a limiting member 44. The storage rack 41 is fixed on the surface of the fixed tube 2. The limiting plate 42 is rotatably installed in the storage rack 41. Two protrusions 43 are fixedly installed on one side of the limiting plate 42. The limiting member 44 works in conjunction with the two protrusions 43. When the limiting plate 42 rotates to squeeze the medicine tube 1, the limiting member 44 can fix the limiting plate 42 to prevent it from loosening.

[0027] Specifically, the storage rack 41 is fixed to one side of the movable tube 3, and a limiting plate 42 is rotatably installed inside the storage rack 41. Two protrusions 43 are fixedly installed on one side of the limiting plate 42, which work in conjunction with the limiting component 44. A medicine tube storage mechanism 4 is provided on the outer wall of the movable tube 3. When not in use, the medicine tube 1 can be neatly wrapped around the outer wall of the movable tube 3, and the wrapped medicine tube 1 is assisted in limiting the position to prevent it from falling off. The idle medicine tube 1 is tightly wrapped around the outer wall of the movable tube 3. Compared with the traditional external storage, it reduces the additional storage space occupied, making the overall structure of the medicine sprayer more compact and easy to carry and store.

[0028] The limiting component 44 includes a fixed base 441, a snap-fit ​​frame 442, a slide groove 443, and a first spring 444. Two slide grooves 443 are provided in the snap-fit ​​frame 442. The fixed base 441 is slidably installed in the slide grooves 443, and one end of the fixed base 441 is fixed to the surface of the movable tube 3. The first spring 444 is provided between the fixed base 441 and the slide grooves 443. When one side of the inner wall of the snap-fit ​​frame 442 is snapped between the two protrusions 43, the limiting plate 42 is snapped and fixed.

[0029] Furthermore, a limiting member 44 is set to fix the rotating limiting plate 42. The sliding groove 443 in the buckle frame 442 is slidably installed with the fixed seat 441. As the buckle frame 442 is pulled, the buckle frame 442 slides on the two fixed seats 441 and stretches the first spring 444, which engages the two protrusions on one side of the limiting plate 42 with the buckle frame 442, thus fixing the limiting plate 42. The fixed seat 441 includes a rectangular seat and a column. The rectangular seat is rotatably installed on the surface of the column. One end of the column is fixed to the outer wall of the movable tube 3, while the rectangular seat slides and adjusts in the sliding groove 443, thereby realizing that the buckle frame 442 can be moved and rotated.

[0030] A slide rod 5 is fixedly installed on one side of the fixed base 441. One end of the slide rod 5 passes through one side of the buckle frame 442 and is provided with an anti-detachment part. The slide rod 5 is movably connected to the first spring 444.

[0031] Specifically, the slide bar 5 is designed to guide the movement of the buckle frame 442 and protect the spring. The surface of the slide bar 5 is provided with an anti-disengagement part to prevent the buckle frame 442 from moving excessively.

[0032] A magnetic block 6 is provided in the groove of the storage rack 41, and the protrusion 43 is a metal block. When the limiting plate 42 is stored in the storage rack 41, the protrusion 43 and the magnetic block 6 are attached to each other, and one end of the limiting plate 42 extends out of the end of the storage rack 41.

[0033] Furthermore, when the limiting plate 42 is not needed to limit the spray tube 1, the limiting plate 42 can be rotated and stored in the storage rack 41. The storage rack 41 has a magnetic block 6 in the groove to limit the protrusion 43 and fix the limiting plate 42 in the storage rack 41. One end of the limiting plate 42 extends out of the end of the storage rack 41, making it easy to move the limiting plate 42 out.

[0034] The outer wall of the movable tube 3 is provided with a winding groove 7 for receiving the spray tube 1;

[0035] Specifically, the winding groove 7 is distributed in a serpentine pattern on the outer wall of the movable rod and is adapted to the spray tube 1. The spray tube 1 is a rubber tube that can be stored in the winding groove 7, providing a guiding effect for the winding of the spray tube 1.

[0036] It also includes a stop 8 for limiting the movement of the movable tube 3. The stop 8 includes a sleeve 81, a second spring 82, a pressing block 83 and a slot 84. The sleeve 81 is embedded in the movable tube 3. The second spring 82 is located in the sleeve 81 and one end is fixedly connected to the pressing block 83. The outer wall of the fixed tube 2 is provided with a slot 84 for the pressing block 83 to abut.

[0037] It is worth noting that the length of the spraying rod can be adjusted by sliding the movable tube 3 on the surface of the fixed tube 2. During the movement of the movable tube 3, the squeezing block 83 is continuously engaged with the squeezing block 83 under the deformation of the second spring 82, which plays a role in assisting the limiting of the movable tube 3. That is, after the movable tube 3 moves, it can play a role in assisting the positioning.

[0038] The sleeve 81 is threaded with an adjusting rod 9. One end of the adjusting rod 9 is fixedly mounted with a push plate 10, which abuts against the other end of the second spring 82.

[0039] The rotating adjusting rod 9 drives the push plate 10 to move, which can squeeze the second spring 82, thereby controlling the squeezing force of the second spring 82 on the squeezing block 83, adjusting the movement of the movable tube 3 to be easy or difficult. In addition, the outer wall of the fixed tube 2 is fixedly installed with a limit strip, and the inner wall of the movable tube 3 is provided with a limit groove, so that the movable tube 3 cannot be rotated for adjustment.

[0040] The spraying end of the spraying pipe 1 is connected to an atomizing nozzle 11, and a serpentine tube 12 is provided between the atomizing nozzle 11 and the fixed pipe 2. The spraying pipe 1 is located inside the serpentine tube 12.

[0041] Specifically, a serpentine tube 12 is provided between the atomizing nozzle 11 and the fixed tube 2, which can fix the atomizing nozzle 11 after rotating at any angle. The characteristic of the serpentine tube 12 being fixed after rotation ensures that the nozzle always maintains the set angle in complex working environments, greatly improving the flexibility of the spraying angle. During operation, the user can freely adjust the bending angle of the serpentine tube 12 and the direction of the nozzle according to the crop height, terrain or spraying needs to accurately cover the target area.

[0042] The threaded connections involved in this application all have a self-locking function, and the threads are coated to prevent dust. Even if a small amount of dust adheres to the threads, they can still be used. This effectively prevents the components of the spraying rod from loosening under high-frequency vibration, long-term use, or external impact. The dustproof coating on the thread surface is made of nano-level polymer material to form a dense protective film, which can effectively block dust, mud, liquid, etc. from entering the thread gap. Even if a small amount of dust adheres to the threads, thanks to the low friction characteristics and self-cleaning ability of the coating, the threads can still maintain smooth engagement without frequent cleaning and maintenance.

[0043] The springs used in this application are all corrosion-resistant springs. The corrosion-resistant springs are made of special alloy material to form a dense protective layer, which effectively resists the corrosion of acid and alkali components and moisture in the pesticide solution. Even if they are in contact with pesticides containing corrosive chemical components for a long time, they can still maintain stable elastic deformation ability.

[0044] This device adjusts the length of the spraying rod by sliding the movable tube 3 on the surface of the fixed tube 2. During the movement of the movable tube 3, the squeezing block 83 is continuously engaged with the squeezing block 83 under the deformation of the second spring 82, which serves to assist in limiting the movement of the movable tube 3. That is, after the movable tube 3 moves, it can assist in positioning. When the spraying rod is not used, the spraying tube 1 is wound in the winding groove 7 on the outer wall of the movable tube 3, and the limiting plate 42 in the storage rack 41 is rotated out so that the limiting plate 42 is located on one side of the wound spraying tube 1, squeezing the spraying tube 1 and pulling the buckle frame 442 to engage the two protrusions 43 on one side of the limiting plate 42 with the buckle frame 442. Under the action of the two second springs 82 in the buckle frame 442, the limiting plate 42 is fixed.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
