Therefore, the invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0021] Reference Figure 1-7The first embodiment of the present invention adopts the following technical solution, including a trapezoidal guide rail 1, the bottom of the trapezoidal guide rail 1 being fixedly installed with the top of the external sales rack, a connecting column 14 being slidably installed on the top of the trapezoidal guide rail 1, a connecting rib 21 being fixedly installed at the bottom of the connecting column 14, an adjusting block 2 being slidably installed on the rear side of the connecting rib 21, support side plates 3 being fixedly installed on both sides of the front side of the adjusting block 2, a spray pipe 68 being rotatably installed on the bottom of the inner side of the support side plate 3, a spray disc 44 being provided on the rear side of the spray pipe 68, the spray disc 44 and the spray pipe 68 being connected to an external hose through a rotary sealing joint, and the hose being connected to an external water source, and also including a translation mechanism, a height adjustment mechanism, a rotary spraying mechanism, and a reciprocating spraying mechanism, the translation mechanism being located on the top of the trapezoidal guide rail 1, and being used to drive the connecting column 14, the height adjustment mechanism, the rotary spraying mechanism, and the reciprocating spraying mechanism to move horizontally; The height adjustment mechanism is located at the bottom of the connecting column 14 and is used to adjust the height of the adjusting block 2, the rotary spraying mechanism, and the reciprocating spraying mechanism. The rotary spraying mechanism is located on the front side of the adjusting block 2, and drives the spraying disc 44 to rotate and spray agricultural products through linkage with the translation mechanism; The reciprocating spraying mechanism is located on the front side of the adjusting block 2, and drives the spray pipe 68 to reciprocate and swing spraying by linkage with the translation mechanism.

[0022] Specifically, an external water source supplies water to the spray disc 44 and spray pipe 68 via a flexible hose and a rotary sealing joint. The translation mechanism drives the connecting column 14 to move horizontally along the trapezoidal guide rail 1, causing the height adjustment mechanism, the rotary spraying mechanism, and the reciprocating spraying mechanism to move synchronously, thus expanding the spray coverage area. The height adjustment mechanism can adjust the height of the adjusting block 2, the spray disc 44, and the spray pipe 68 according to the stacking height of agricultural products, thereby adapting to the preservation needs of different stack heights. During the translation process, the rotary spraying mechanism drives the spray disc 44 to rotate, spraying the agricultural products in the area in 360° all-round way. At the same time, the reciprocating spraying mechanism drives the spray pipe 68 to swing back and forth, enhancing the uniformity of spraying in local areas. Example 2

[0023] In the second embodiment of the present invention, the following technical solution is adopted: the translation mechanism includes a servo motor 11, a lead screw 12, and a trapezoidal slider 13. Shaft brackets 121 are fixedly installed on both sides of the top of the trapezoidal guide rail 1. The left side of the servo motor 11 is fixedly installed with a set of shaft brackets 121 located on the top left side of the trapezoidal guide rail 1. Both ends of the lead screw 12 are rotatably installed with the two sets of shaft brackets 121. The right end of the lead screw 12 passes through the shaft bracket 121 and is fixedly installed with the output end of the servo motor 11. The trapezoidal slider 13 is threadedly connected to the surface of the lead screw 12. The groove of the trapezoidal slider 13 slides with the trapezoidal guide rail 1. The top of the trapezoidal slider 13 is fixedly installed with the front side of the bottom of the connecting column 14. The height adjustment mechanism includes a screw 22, a retaining ring 23, and a trapezoidal slide bar 25. The screw 22 rotates... The screw 22 is threaded to the bottom of the surface of the connecting column 14. The front side of the adjusting block 2 is provided with a trapezoidal groove 24. The trapezoidal slide 25 is fixedly installed at the bottom of the rear side of the connecting rib 21. The trapezoidal groove 24 and the trapezoidal slide 25 are in sliding cooperation. The retaining ring 23 is fixedly installed at the top of the surface of the screw 22 and is located at the bottom of the connecting column 14. The rotating spraying mechanism includes a toothed plate 4, a large gear 41 and a fixed rod 42. The toothed plate 4 is fixedly installed to the external sales rack. The fixed rod 42 is fixedly installed at the top of the spray disc 44. The large gear 41 is fixedly installed at the top of the surface of the fixed rod 42 and meshes with the toothed plate 4. A water shield 7 for blocking the water mist splashed from the spray disc 44 is fixedly installed on the rear side of the supporting side plate 3.

[0024] Specifically, by starting the servo motor 11, the output end drives the lead screw 12 to rotate. The two sets of shaft brackets 121 provide stable support for the rotation of the lead screw 12. Since the trapezoidal slider 13 is threadedly connected to the lead screw 12 and the groove is slidably engaged with the trapezoidal guide rail 1, the rotation of the lead screw 12 can drive the trapezoidal slider 13 to move horizontally along the trapezoidal guide rail 1. This, in turn, drives the height adjustment mechanism, the rotary spraying mechanism, and the reciprocating spraying mechanism to move synchronously through the connecting column 14. By manually rotating the screw 22, since the adjusting block 2 is threadedly connected to the screw 22 and its front trapezoidal groove 24 is slidably engaged with the trapezoidal slide strip 25 behind the connecting rib 21, the adjustment block 2 then rotates. The adjusting block 2 moves up and down along the screw 22 to adjust the height of the supporting side plate 3, the spray disc 44, and the spray pipe 68. The retaining ring 23 prevents the screw 22 from falling. During the horizontal movement, the fixing rod 42 on the top of the spray disc 44 moves synchronously with the supporting side plate 3. The large gear 41 on the surface of the fixing rod 42 meshes with the fixed tooth plate 4. While moving horizontally, the large gear 41 can be driven to rotate, which in turn drives the spray disc 44 to rotate synchronously through the fixing rod 42, realizing rotational spraying. The water shield 7 on the rear side of the supporting side plate 3 can block the water mist splashed when the spray disc 44 rotates, avoiding water waste and a damp surrounding environment. Example 3

[0025] The third embodiment of the present invention adopts the following technical solution: the reciprocating spraying mechanism includes a transmission assembly, a torsion assembly, a fixed block 5, a support frame 51, a fixed shaft 6, a cam 62, a rotating pin 63, and a limiting plate 64. The fixed block 5 is fixedly installed at the center of the front side of the adjusting block 2. The support frame 51 is fixedly installed on the front side of the fixed block 5. The fixed shaft 6 is arranged laterally, and its surface is rotatably mounted to the front side of the support frame 51. The cam 62 is fixedly installed at the left end of the fixed shaft 6. The rotating pin 63 is fixedly installed on the left side of the cam 62 and is eccentrically arranged. The limiting plate 64 is arranged laterally on the left side of the cam 62. A limiting groove is formed on the surface of the limiting plate 64, and the limiting groove slides with the surface of the rotating pin 63. The transmission assembly is located at the top of the surface of the fixed rod 42 and is used to transmit power. The torsion assembly is located at the bottom of the limiting plate 64 and is used to drive the spray pipe 68 to perform reciprocating swing motion. The transmission assembly includes a first bevel gear 43 and a second bevel gear 61. The first bevel gear 43 is fixedly installed on the top of the surface of the fixed rod 42, and the second bevel gear 61 is fixedly installed on the right end of the fixed shaft 6. The second bevel gear 61 meshes with the first bevel gear 43. The torsion assembly includes a lifting plate 65 and a pinion 67. The lifting plate 65 is fixedly installed at the center of the bottom of the limiting plate 64. Several sets of teeth 66 are opened on the bottom of the front side of the lifting plate 65. The pinion 67 is fixedly installed on the left side of the surface of the spray pipe 68. The pinion 67 meshes with the teeth 66. An anti-sway U-shaped plate 8 is slidably installed on the top of the surface of the lifting plate 65. The left side of the anti-sway U-shaped plate 8 is fixedly installed on the inner side of a set of support side plates 3.

[0026] Specifically, when the spray disc 44 rotates, the bevel gear 43 on the surface of its top fixed rod 42 rotates synchronously. Through meshing with the bevel gear 61 at the right end of the fixed shaft 6, it drives the fixed shaft 6 to rotate on the support frame 51, thereby causing the cam 62 at the left end of the fixed shaft 6 to rotate. This causes the eccentrically positioned rotating pin 63 on the left side of the cam 62 to rotate with the cam 62 and slide within the limiting groove of the limiting plate 64, forcing the limiting plate 64 to perform a reciprocating translational motion laterally. When the limiting plate 64 translates, its… The bottom lifting plate 65 moves back and forth synchronously. The teeth 66 on the bottom front side of the lifting plate 65 mesh with the small gear 67 on the surface of the spray pipe 68. Through meshing transmission, the small gear 67 and the spray pipe 68 swing back and forth. At the same time, the top of the lifting plate 65 slides with the anti-sway U-shaped plate 8. The anti-sway U-shaped plate 8 is fixed to the inside of the support side plate 3, which can limit the swaying of the lifting plate 65 and ensure the stability of the reciprocating motion. Finally, the spray pipe 68 sprays agricultural products back and forth. Working principle

[0027] An external water source supplies water to the spray disc 44 and spray pipe 68 via a hose and a rotary sealing joint. The servo motor 11 drives the lead screw 12 to rotate, causing the trapezoidal slider 13 to move horizontally along the trapezoidal guide rail 1. This, in turn, causes the height adjustment mechanism, the rotary spraying mechanism, and the reciprocating spraying mechanism to move synchronously through the connecting column 14, expanding the spraying range. By manually rotating the screw 22, the height of the adjusting block 2 and related spraying components can be adjusted using the threaded engagement between the adjusting block 2 and the screw 22, and the sliding guidance between the trapezoidal groove 24 and the trapezoidal slide 25, adapting to agricultural products of different heights. During the translation process, the large gear 41 on the fixed rod 42 meshes with the fixed toothed plate 4. The spraying mechanism drives the spray disc 44 to rotate, achieving 360° rotating spraying. The water shield 7 can prevent water mist from splashing. At the same time, the fixed rod 42 drives the fixed shaft 6 to rotate through the meshing of bevel gear 1 43 and bevel gear 2 61. The cam 62 rotates with the fixed shaft 6, and its eccentric rotating pin 63 slides in the limiting groove of the limiting plate 64, forcing the limiting plate 64 and the lifting plate 65 to move back and forth. The lifting plate 65 drives the spray pipe 68 to swing back and forth through the meshing of the teeth 66 and the pinion 67. The anti-sway U-shaped plate 8 ensures the stable movement of the lifting plate 65. The combination of rotating spraying and reciprocating spraying can achieve comprehensive and uniform spraying of agricultural products at different areas and heights.

[0028] In summary, by combining trapezoidal guide rails, connecting columns, connecting ribs, adjusting blocks, supporting side plates, spray pipes, spray discs, translation mechanisms, height adjustment mechanisms, rotating spraying mechanisms, and reciprocating spraying mechanisms, the problems of low efficiency, limited coverage of fixed devices, and difficulty in adapting to multi-layered agricultural and sideline products caused by traditional manual water spraying are solved.
