Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0020] Embodiment one

[0021] Referring to Figures 1-14 The present application provides a technical solution: a corn silk automatic cleaning and drying equipment, comprising a processing box 1, a discharge assembly 2, a clamping assembly 3, a driving assembly 4 and a drying assembly 5. The top of the processing box 1 is provided with a box cover 11, the inside of the side wall of the processing box 1 is provided with a gas guide cavity 12, and the inner top surface of the processing box 1 is provided with an air outlet hole 13. In use, first, the corn silk 6 is clamped by the clamping assembly 3, then the box cover 11 is opened and water is added to the processing box 1. Then the driving assembly 4 works to drive the clamping assembly 3 and the corn silk 6 to immerse in the water, then the box cover 11 is closed, the driving assembly 4 drives the clamping assembly 3 and the corn silk 6 to rotate continuously in the water, the corn silk 6 is cleaned, and then the discharge assembly 2 works to discharge the sewage in the processing box 1 out of the processing box 1. Then the drying assembly 5 works to send hot air into the gas guide cavity 12, the hot air in the gas guide cavity 12 blows to the clamping assembly 3 and the corn silk 6 through the air outlet hole 13, and the discharge assembly 2 discharges the humid air in the processing box 1 out of the processing box 1. When the clamping assembly 3 and the corn silk 6 are dried, the box cover 11 is opened, the driving assembly 4 drives the clamping assembly 3 and the corn silk 6 to leave the processing box 1, and the corn silk 6 is taken away. Since the cleaning and drying of the corn silk 6 are completed in the inside of the processing box 1, the corn silk 6 will not be contaminated with new impurities or dust, and the cleaning effect of the corn silk 6 and the quality of the corn silk 6 in the drying process can be improved.

[0022] Referring to Figures 1-6 The discharge assembly 2 comprises a first discharge pipe 21, a second discharge pipe 22, a first electric control valve 23, a second electric control valve 24 and a third electric control valve 25. When water is added to the processing box 1 and the corn silk 6 is cleaned, the first electric control valve 23, the second electric control valve 24 and the third electric control valve 25 are all in the closed state. When the cleaning of the corn silk 6 is completed, the third electric control valve 25 is in the closed state, and the first electric control valve 23 and the second electric control valve 24 are both opened, so that the first discharge pipe 21 can discharge the sewage in the processing box 1. When the corn silk 6 is dried, the second electric control valve 24 is in the closed state, and the first electric control valve 23 and the third electric control valve 25 are both opened, so that the first discharge pipe 21 and the second discharge pipe 22 can discharge the humid air in the processing box 1.

[0023] Referring to Figures 1-8The clamping assembly 3 comprises a guide frame 31, a plurality of first pressure pieces 32, a second pressure piece 33, a locking piece 34 and an extension rod 35. The guide frame 31 comprises a plurality of equidistantly distributed guide rods 312, the first pressure pieces 32 and the second pressure piece 33 are arranged on the inner side of the guide rods 312, and the top of the extension rod 35 is provided with a limiting rod 351. When it is needed to clamp the corn silk, the locking piece 34 is first removed from the limiting rod 351, and then the first pressure pieces 32 and the second pressure piece 33 are removed. Subsequently, a small amount of corn silk 6 is placed between the bottoms of the adjacent two guide rods 312, and then one first pressure piece 32 is taken to press on the top of the corn silk 6, at this time the corn silk 6 is clamped by the guide frame 31 and the first pressure piece 32. Repeat the above operation, and the corn silk 6 of several layers is pressed by the first pressure pieces 32, until the last first pressure piece 32 is placed, and the second pressure piece 33 is pressed on the top of the top layer of corn silk 6. Finally, the locking piece 34 is reinstalled on the limiting rod 351, and the locking piece 34 can limit the second pressure piece 33, at this time the first pressure pieces 32 and the second pressure piece 33 will not be loose, and the corn silk 6 can be clamped by the clamping assembly 3.

[0024] Please refer to Figures 1-4 The top of the processing box 1 is in a semispherical structure, and a plurality of air outlets 13 are radially distributed to ensure that the hot air blown out of the air outlets 13 can be accurately blown to the corn silk 6. The top surface of the processing box 1 is provided with an assembly opening 14, and the box cover 11 is arranged in the assembly opening 14 and hinged to the inner wall of the assembly opening 14, so as to facilitate opening and closing of the box cover 11. When the clamping assembly 3 reaches the predetermined position in the processing box 1, the included angle between the extension rod 35 and the horizontal plane is α, and 40°≤α≤60°. In this embodiment, α is 45°. Therefore, when the corn silk 6 rotates in the water, the corn silk 6 can change in height, so that the impurities and dust carried by the corn silk 6 can be washed away more quickly. The end face of the box cover 11 close to the extension rod 35 is provided with an arc-shaped groove 111 arranged obliquely, when the extension rod 35 enters the processing box 1 and the box cover 11 is closed, the extension rod 35 is attached to the inner wall of the arc-shaped groove 111. When the extension rod 35 rotates along the axis, the extension rod 35 can slide along the inner wall of the arc-shaped groove 111, thereby enhancing the stability of the extension rod 35 during rotation.

[0025] Please refer to Figures 1-5 and Figure 14The driving assembly 4 comprises a base 41, a first motor 42, a position adjusting frame 43 and a second motor 44, and the drying assembly 5 comprises a blower 51 and an electric heating wire 52. The first motor 42 is arranged on the top of the base 41, the output end of the first motor 42 is connected with the position adjusting frame 43, the second motor 44 is arranged on the position adjusting frame 43, and the output end of the second motor 44 is connected with the extension rod 35. The blower 51 is arranged on the bottom of the base 41, and the electric heating wire 52 is arranged in the air guiding cavity 12. When the first motor 42 works, the extension rod 35 can be rotated in the vertical plane through the position adjusting frame 43 and the second motor 44, thereby driving the corn silk 6 to move to the inside of the treatment box 1 and immerse in the water. When the second motor 44 works, the extension rod 35 can be rotated along the axis, thereby driving the corn silk 6 to rotate continuously, and the cleaning work of the corn silk 6 in the water is completed. After the sewage is discharged from the treatment box 1 through the discharge assembly 2, the blower 51 sends the external air into the air guiding cavity 12, the electric heating wire 52 heats the air in the air guiding cavity 12, then the hot air blows to the corn silk 6 through the air outlet hole 13, the second motor 44 drives the corn silk 6 to rotate continuously, and the drying work of the corn silk 6 is completed.

[0026] Example two

[0027] On the basis of example one, please refer to Figure 2 、 Figures 7-9 and Figure 12 The first pressure piece 32 comprises a plurality of first protruding parts 3211, the second pressure piece 33 comprises a plurality of second protruding parts 3311, and the assembly space 313 is formed between the adjacent two guide rods 312. The first protruding part 3211 and the second protruding part 3311 both extend into the plurality of assembly spaces 313 and can slide along the outer surface of the guide rod 312. The guide frame 31 further comprises a bearing ring 311, the bearing ring 311 is fixedly connected with the extension rod 35, and the bottom of the plurality of guide rods 312 is connected with the bearing ring 311. The bearing ring 311, the first protruding part 3211 and the plurality of second protruding parts 3311 complete the clamping work of the corn silk 6. The guide rod 312 can limit the first pressure piece 32 and the second pressure piece 33, so as to ensure that the first pressure piece 32 and the second pressure piece 33 will not rotate and separate from the guide frame 31. In the vertical direction, the projection of the guide rod 312 coincides with the bearing ring 311. That is to say, the guide rod 312 has a spiral structure, when the plurality of first pressure pieces 32 and the second pressure pieces 33 are all placed on the inner side of the plurality of guide rods 312, the plurality of first protruding parts 3211 and the plurality of second protruding parts 3311 also form a spiral distribution in the vertical direction, so that the corn silk 6 in each assembly space 313 also forms a spiral distribution after being clamped, thereby increasing the gap between the corn silk 6 at different heights. Not only can the impurities and dust on the corn silk 6 be more easily washed away, but also the drying time of the corn silk 6 can be shortened.

[0028] Example three

[0029] On the basis of embodiment one, please refer to Figures 1-2 and Figures 7-11 The first pressure piece 32 includes a pressure ring 321, a sleeve ring 322 and a stabilizing rod 323. The sleeve ring 322 is sleeved on the outer surface of the limiting rod 351, and when the first pressure piece 32 is taken away or put in from the inner side of the guide rod 312, the sleeve ring 322 slides along the outer surface of the limiting rod 351, ensuring that the center axes of the plurality of first pressure pieces 32 coincide, and the stabilizing rod 323 can ensure that the pressure ring 321 is not easily deformed and damaged. When the corn silk 6 continues to rotate in the water, the water can quickly pass through the gap between the pressure ring 321 and the sleeve ring 322. The inside of the stabilizing rod 323 is provided with a plurality of water-permeable holes 3231, which can also quickly pass through the stabilizing rod 323 after contacting the water. The entire first pressure piece 32 has very small resistance in water, so it can protect the second motor 44 and prolong the service life of the driving assembly 4.

[0030] Please refer to Figures 9-11 The water-permeable hole 3231 has an S-shaped structure. Since the corn silk 6 swings randomly at the end when it rotates in the water, the curved structure of the water-permeable hole 3231 can ensure that the corn silk 6 is difficult to pass through the water-permeable hole 3231, and ensure that the corn silk 6 will not be inserted into the water-permeable hole 3231 after drying. Therefore, the corn silk 6 can be easily taken out and will not be broken in the water-permeable hole 3231. The water-permeable hole 3231 is provided with a water guide arc surface 3232 at both ends of the opening, which makes the water more easily pass through the water-permeable hole 3231, further reducing the resistance of the first pressure piece 32 in water.

[0031] Embodiment four

[0032] On the basis of embodiment one, please refer to Figures 1-2 , Figure 7 and Figure 12 The second pressure piece 33 includes a pressure plate 331, and the center of the pressure plate 331 is provided with an assembly hole 3312. The pressure plate 331 is provided with a plurality of water holes 3313 arranged around the assembly hole 3312. When the second pressure piece 33 is taken away or put in from the inner side of the guide rod 312, the limiting rod 351 is arranged in the assembly hole 3312, and the pressure plate 331 can slide along the outer surface of the limiting rod 351. When the corn silk 6 continues to rotate in the water, the water can quickly pass through the water hole 3313. The entire second pressure piece 33 has very small resistance in water, so it can protect the second motor 44 and prolong the service life of the driving assembly 4.

[0033] Please refer to Figures 1-2 , Figure 7 and Figures 12-13The second pressure piece 33 further comprises a rubber ring 332, the locking piece 34 comprises a knob 341, a threaded rod 342 and a pressing rod 343, and the top surface of the limiting rod 351 is provided with a threaded hole 352. When the knob 341 is twisted reversely, the threaded rod 342 can move upward in the threaded hole 352, and the locking piece 34 can be detached from the limiting rod 351. When the knob 341 is twisted forwardly, the threaded rod 342 can move downward in the threaded hole 352, and the threaded rod 342 drives the knob 341 and the pressing rod 343 to move downward together, and when the bottom of the pressing rod 343 presses the top surface of the rubber ring 332 to the recess, the installation of the locking piece 34 is completed. The rubber ring 332 can increase the friction between the locking piece 34 and the second pressure piece 33, and when the corn silk 6 continuously rotates in water, the relative displacement between the locking piece 34 and the second pressure piece 33 will not be generated, so that the corn silk 6 can be clamped by the clamping assembly 3 firmly.

[0034] It will be obvious to a person skilled in the art that, without departing from the spirit or essential characteristics of the application, the present application can be implemented in other specific forms. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the description given above, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that, although the present specification describes particular embodiments, each of which contains only a single independent technical solution, the specification is written in such a way as to be clear and concise, and a person skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by a person skilled in the art.
