[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0016] Reference Figure 1-3 This is the first embodiment of the present invention. This embodiment provides an automatic spraying system for color-protecting liquid to prevent browning of dried mangoes, including spraying components: including a frame 10 and a spraying assembly 14. A shielding frame 13 is provided on the upper side of the frame 10, and a spraying table assembly 12 is provided on the top of the shielding frame 13. A receiving mesh frame 15 is inserted into the inner wall of the frame 10.

[0017] Furthermore, the spraying platform assembly 12 includes a drive motor 122 fixedly mounted on the inner wall of the shielding frame 13 and a main roller 121 and a secondary roller 125 movably mounted on the inner wall of the shielding frame 13. One end of the main roller 121 and the secondary roller 125 is fixedly connected to a first transmission gear 124. The output shaft of the drive motor 122 is fixedly connected to a drive gear 123 through a coupling. The outer walls of the main roller 121 and the secondary roller 125 are provided with multiple anti-slip protrusions.

[0018] The spraying assembly 14 includes a liquid mixing tank 144 and a lower spraying plate 145. A side lifting hydraulic cylinder 143 is fixedly connected to the outer wall of the lower spraying plate 145. One end of the side lifting hydraulic cylinder 143 is fixedly connected to an upper spraying plate 141. A draining chamber is provided on the inner wall of the upper spraying plate 141. Several spray heads 142 are provided at the bottom of the upper spraying plate 141. A liquid receiving groove 146 is opened on the top of the lower spraying plate 145. A liquid collection groove is provided on the inner wall of the lower spraying plate 145. Several atomizing nozzles 147 are provided on the top of the lower spraying plate 145. Several atomizers are provided at the bottom of the lower spray plate 145, and the atomizers are connected to the atomizing nozzles 147; A drain pipe is fixedly connected between the liquid mixing tank 144 and the upper spraying plate 141, and a booster pump is installed at the connection between the drain pipe and the liquid mixing tank 144.

[0019] Preferably, there are two platforms 10. One platform 10 has a lifting seat 11 fixedly connected to its bottom. The lifting seat 11 includes a lower lifting hydraulic cylinder. The upper and lower ends of the lower lifting hydraulic cylinder are fixedly connected to connecting plates. The bottom of the lifting seat 11 is fixedly connected to a pulley. The bottom of the other platform 10 is hinged to a fixed support column.

[0020] It should be noted that the receiving mesh frame 15 is located below the spraying platform assembly 12, the lower spraying plate 145 is located at the bottom of the receiving mesh frame 15, and the upper spraying plate 141 is located above the spraying platform assembly 12.

[0021] In use, firstly, the prepared color-protecting liquid is injected into the mixing tank 144. Then, the side lifting hydraulic cylinder 143 is started and controlled to raise the upper spray plate 141. The sliced ​​mangoes or dried mangoes are poured onto the main roller 121 and the auxiliary roller 125. The drive motor 122 is started and controlled to drive the first transmission gear 124, which is meshed with the drive gear 123, to rotate. This causes the main roller 121 and all the auxiliary rollers 125 in the spray table assembly 12 to rotate, thereby dispersing the mangoes or dried mangoes from the bottom to both sides. The side lifting hydraulic cylinder 143 is used to raise and lower the position of the upper spray plate 141, so that the spray head 142 on the upper spray plate 141 is as close as possible to the top of the mango to be sprayed with color-protecting liquid, reducing the splashing of color-protecting liquid during the spraying process. Excess color-protecting liquid drips from the mango into the liquid receiving tank 146 and finally falls into the liquid collection tank. Then, the recovered color-protecting liquid is atomized by the atomizer set in the lower spray plate 145 and discharged upward through the atomizing nozzle 147, thereby realizing the bottom of the mango to be dyed from below the main roller 121 and the auxiliary roller 125, ensuring that the mango fully absorbs the color-protecting liquid. Example 2

[0022] Reference Figure 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides: Dispersion component: includes a rack and pinion limit frame 20 fixedly installed on the outer wall of the frame 10, an upper dispersion component 21 is movably connected to the inner wall of the rack and pinion limit frame 20, and a cleaning component 23 is provided on the outer wall of the upper dispersion component 21. Specifically, the upper dispersing component 21 includes a transmission toothed belt 211 inserted into the inner wall of the platform 10. A fixed connecting block 214 is fixedly connected to the outer wall of the transmission toothed belt 211. A first connecting crossbar 212 is fixedly connected to the outer wall of the fixed connecting block 214. Several small actuating blocks 213 are provided at the bottom of the first connecting crossbar 212. A connecting ball is fixedly connected to the top of the small actuating blocks 213. The top of the small actuating blocks 213 is movably connected to the bottom inner wall of the first connecting crossbar 212 through the connecting ball. The outer wall of the main roller 121 is fixedly connected to the second transmission gear 22, and the outer wall of the second transmission gear 22 is meshed with the inner wall of the transmission toothed belt 211.

[0023] The cleaning component 23 includes a movable connecting block 231 fixedly mounted on the transmission toothed belt 211. The inner wall of the movable connecting block 231 is movably connected to a second connecting crossbar 232 via a movable pin. The top of the second connecting crossbar 232 is provided with several bristles 233. Both the fixed connecting block 214 and the movable connecting block 231 are slidably mounted on the inner wall of the shielding frame 13.

[0024] In use, during the operation steps of embodiment 1 above, as the drive motor 122 drives the first transmission gear 124, which meshes with the drive gear 123, to rotate, the second transmission gear 22 on the main roller 121 also rotates accordingly. This causes the transmission belt 211 to move along the inner wall of the frame 10 and the rack and pinion limit frame 20, so that the first connecting crossbar 212 and the second connecting crossbar 232 on the transmission belt 211 move to a certain extent along the direction of the shielding frame 13. This, in turn, pushes the stacked mango slices or dried mangoes flat from above by the small actuating block 213, reducing the stacking thickness of the dried mangoes. The aim is to ensure that the dried mangoes are laid out in a single layer on the main roller 121 and the auxiliary roller 125, allowing for more comprehensive absorption of the color-protecting liquid. At the same time, the movable connection between the small agitator 213 and the first connecting crossbar 212 allows for flexible contact between the small agitator 213 and the dried mangoes, reducing damage to the dried mangoes during leveling. Meanwhile, the bristles 233 on the second connecting crossbar 232 contact the bottom of the spray head 142 above the upper spray plate 141, thereby cleaning the drain port of the spray head 142 during the movement of the bristles 233, ensuring a smooth spraying effect during the spraying process.

[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
