[0002] Sprayers are mainly used to spray water mist, pesticides, herbicides, etc. on plants to provide water, control pests and diseases, and weed, so as to irrigate them evenly and ensure that the plants fully absorb water through fine water mist or uniform water flow, avoiding water waste and plant damage.

[0003] In agriculture, plant sprayers are used to spray water or pesticides from the tank onto plants for absorption. However, in the current sprayers, water or pesticides are sprayed out from the spray bar through the delivery pipe during use. Moreover, the delivery pipe lacks a limiting structure, which makes it easy for the delivery pipe to be placed randomly after the sprayer is finished, making it difficult to store and affecting subsequent use.

A rotating hole 25 is opened on the surface of the mounting plate 23. A slot 26 is opened on the surface of the movable plate 22. A torsion spring 27 is sleeved on the surface of the rotating rod 24. Under the action of the limiting plate 2, the rotation of the movable plate 22 can be limited to control the range of motion of the movable plate 22.

[0025] Two sets of limiting plates 2 and fixing plates 21 are provided, and the two sets of limiting plates 2 and fixing plates 21 are installed on both sides of the tank body 1. The cross-section of the limiting plates 2 and fixing plates 21 is "L" shaped. One end of the movable plate 22 is abutted and connected to the surface of the limiting plate 2, and the other end of the movable plate 22 is movably connected to the surface of the fixing plate 21. The movable plate 22 can limit the conveying pipe 13 wound on the two sets of fixing plates 21 to prevent the conveying pipe 13 from falling off the surface of the fixing plate 21 during the winding process. Two sets of mounting plates 23 and rotating rods 24 are provided, and the two sets of mounting plates 23 and rotating rods 24 are installed on both sides of the fixing plate 21. The rotating rods 24 are rotatably connected to the surface of the rotating holes 25. The diameter of the rotating holes 25 is the same as the diameter of the rotating rods 24. With the connection of the rotating rods 24 and the rotating holes 25, the movable plate 22 and the mounting plate 23 can rotate together around the rotating rods 24. There are two sets of slots 26. One set of slots 26 is opened on the surface of the fixed plate 21, and the other set of slots 26 is opened on the surface of the movable plate 22. There are two slots 26 in each set.

The set of slots 26 on the fixed plate 21 is opened on both sides, and the set of slots 26 on the movable plate 22 is also opened on both sides. The torsion spring 27 can apply torsion force to the surfaces of the fixed plate 21 and the movable plate 22, so that the movable plate 22 always has a tendency to move outward towards the limit plate 2.

[0026] The surface of the conveying pipe 13 is provided with a protective mechanism, which includes a connecting pipe 3. The connecting pipe 3 is fixedly connected to the surface of the tank body 1. A sleeve 31 is installed on the surface of the conveying pipe 13. A screw hole 32 is opened on the surface of the connecting pipe 3. An insertion hole 33 and a through hole 35 are opened on the surface of the sleeve 31. A screw 34 is installed on the surface of the sleeve 31. A protective sleeve 36 is installed on the surface of the sleeve 31. The connection between the tank body 1 and the conveying pipe 13 is located on the inner surface of the connecting pipe 3 and the sleeve 31, forming a protective structure to protect the connection. The outer diameter of the connecting pipe 3 is the same as the inner diameter of the sleeve 31. The sleeve 31 is fitted onto the outer surface of the connecting pipe 3. There are two sets of screw holes 32 and insertion holes 33. The two sets of screw holes 32 are opened on both sides of the connecting pipe 3, and the two sets of insertion holes 33 are opened on the surface of the sleeve 31. The screw 34 is inserted and connected to the surface of the insertion hole 33. The screw 34 can be installed through the screw holes 32 and insertion holes 33. The two sets of screw holes 32 and insertion holes 33 are symmetrically distributed on both sides of the connecting pipe 3 and the sleeve 31. One end of the screw 34 is threaded to the surface of the screw hole 32, and the other end of the screw 34 is abutted to the outer surface of the sleeve 31. The outer surface of the sheath 36 is movably connected to the surfaces of the sleeve 31 and the through hole 35. The inner surface of the sheath 36 is fitted onto the surface of the conveying pipe 13. With the connection of the screw 34, the screw hole 32, and the insertion hole 33, the connection between the connecting pipe 3 and the sleeve 31 can be formed, and the sleeve 31 can be disassembled and assembled. The sheath 36 and the conveying pipe 13 can be installed through the through hole 35. The cross-section of the sheath 36 is U-shaped and its two sides are attached to the inner and outer sides of the sleeve 31. The sheath 36 is made of rubber to protect the connection between the conveying pipe 13 and the through hole 35.

[0027] Working principle: When receiving the conveying pipe 13, the conveying pipe 13 is first placed between the limiting plate 2 and the fixed plate 21 and pressed against the surface of the movable plate 22, so that the movable plate 22 and the mounting plate 23 rotate together around the rotating rod 24. The torsion spring 27 is twisted and moves on the rotating rod 24. At this time, the conveying pipe 13 slides along the movable plate 22 and wraps around the surface of the two sets of fixed plates 21 in sequence. Afterwards, when the movable plate 22 is not squeezed, it will return to its original position under the torsional force applied by the torsion spring 27 and press against the limiting plate 2, so as to achieve the effect of limiting the conveying pipe 13 on the fixed plate 21.

[0028] Before using the conveying pipe 13, move the sleeve 31 and slide the sheath 36 onto the surface of the conveying pipe 13. Then, put the sleeve 31 on the outer surface of the connecting pipe 3. Next, adjust the sleeve 31 by rotating it so that the screw hole 32 and the insertion hole 33 are aligned. Then, insert the screw 34 into the insertion hole 33 and turn the screw 34 with a Phillips screwdriver so that the small end is threaded onto the surface of the screw hole 32, while the large end is pressed against the outer surface of the sleeve 31. This completes the installation of the sleeve 31 and provides protection for the connection of the conveying pipe 13.
