DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] In one embodiment, see Figure 1 and Figure 2A drying device for functional seasonings comprises a drying box 1, wherein a drying mechanism 3 is arranged inside the drying box 1, and the drying mechanism 3 is used for drying the functional seasonings. An air outlet duct 7 is connected to the side wall of the drying box 1, and a mesh plate 8 is arranged inside the air outlet duct 7. A back-blowing mechanism 4 is arranged on the side of the mesh plate 8 away from the drying box 1. A bracket 5 is fixed to the top of the drying box 1, and a motor 6 is installed on the top of the bracket 5. A rotating rod 9 is installed at the output end of the motor 6. A transmission rod 10 is arranged below the rotating rod 9. The lower end of the rotating rod 9 extends into the transmission rod 10 and is slidably connected with the transmission rod 10, wherein an adjusting mechanism 2 is arranged between the rotating rod 9 and the transmission rod 10, and the adjusting mechanism 2 is used to adjust the height of the transmission rod 10, so that the transmission rod 10 can drive the drying mechanism 3 or the back-blowing mechanism 4 to operate.

[0027] When the functional seasoning is dried by the device, the functional seasoning is poured into the drying box 1 through the feeding port at the top of the drying box 1, and the discharging port at the bottom of the drying box 1 is in a closed state. After the functional seasoning is poured into the drying box 1, the feeding port at the top of the drying box 1 is closed, and then the motor 6 is started, and the motor 6 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the transmission rod 10 to rotate through the adjusting mechanism 2. At this time, the transmission rod 10 rotates and drives the drying mechanism 3 to operate, and the functional seasoning in the drying box 1 is adjusted by the drying mechanism 3, wherein the side wall of the drying box 1 is connected with an air outlet duct 7, and the gas in the drying box 1 can be smoothly discharged to the outside of the drying box 1 through the air outlet duct 7, and the gas can also take away the moisture in the drying box 1 while being discharged, thereby effectively improving the drying effect of the functional seasoning, and at the same time, the particulate matter in the functional seasoning is intercepted by the mesh plate 8 inside the air outlet duct 7, thereby preventing the functional seasoning from The particulate matter is discharged to the outside of the drying box 1, thereby reducing the loss rate and saving costs. After the functional seasoning in the drying box 1 is dried, the discharge port at the bottom of the drying box 1 is opened, and the dried functional seasoning is discharged to the outside of the drying box 1 along the discharge port. In the process of discharging the functional seasoning, the height of the transmission rod 10 is lowered by the adjusting mechanism 2. At this time, the transmission rod 10 will not drive the drying mechanism 3 to operate while rotating, but will drive the back-blowing mechanism 4 to operate. The back-blowing mechanism 4 back-blows the mesh plate 8, which can effectively blow the particulate matter adsorbed on the surface of the mesh plate 8 into the drying box 1 again. After these functional seasonings are blown into the drying box 1, they are finally discharged from the discharge port. Through the setting of the back-blowing mechanism 4, the phenomenon of poor ventilation caused by the functional seasoning being adsorbed on the surface of the mesh plate 8 due to long-term use of the device can be effectively avoided, while waste can be avoided, cost can be saved, and there is no need to manually clean the surface of the mesh plate 8, saving manpower.

[0028] See also Figure 3The adjusting mechanism 2 includes a first fixing plate 21 fixedly connected to the rotating rod 9 and a second fixing plate 22 fixedly connected to the transmission rod 10, the first fixing plate 21 is fixedly connected with symmetrically distributed limiting rods 28, the limiting rods 28 all penetrate the second fixing plate 22 and are slidably connected to the second fixing plate 22, the limiting rods 28 are provided with first elastic members 23 on the outside, the two ends of the first elastic member 23 are respectively fixedly connected to the first fixing plate 21 and the second fixing plate 22, wherein the second fixing plate 22 is provided with a fixing assembly inside, and the fixing assembly is used to fix the limiting rods 28; When the functional seasoning is dried, the motor 6 is started, and the motor 6 drives the rotating rod 9 to rotate. The rotating rod 9 drives the first fixed plate 21 to rotate while rotating. The first fixed plate 21 drives the second fixed plate 22 to rotate through the limiting rod 28. The second fixed plate 22 drives the transmission rod 10 to rotate while rotating. The first fixed plate 21, the limiting rod 28 and the second fixed plate 22 are arranged so that the transmission rod 10 can rotate with the rotating rod 9. At this time, the transmission rod 10 can drive the drying mechanism 3 to operate while rotating, so that the drying mechanism 3 can dry the functional seasoning inside the drying box 1. When the functional seasoning is dried, the motor 6 stops running and lowers the height of the transmission rod 10 through the adjusting mechanism 2. Then the motor 6 is started again. At this time, the transmission rod 10 can drive the back-blowing mechanism 4 to operate while rotating. The mesh plate 8 is back-blown by the back-blowing mechanism 4, so that the particulate matter adsorbed on the surface of the mesh plate 8 is blown into the drying box 1 again. This can effectively avoid the phenomenon of poor ventilation caused by the functional seasoning being adsorbed on the surface of the mesh plate 8 due to long-term use of the device, while also avoiding waste and saving costs. The first elastic member 23 can play an elastic supporting role for the second fixed plate 22, thereby ensuring the stability of the second fixed plate 22. The first elastic member 23 can be a spring, and the two positions of the second fixed plate 22 can be fixed separately through the fixing assembly, thereby effectively improving the stability of the transmission rod 10 when it rotates.

[0029] See also Figure 3 The fixing assembly includes two positioning holes 26 arranged on the side wall of the limiting rod 28 and distributed oppositely. The side wall of the second fixing plate 22 is penetrated by positioning rods 25 which are symmetrically distributed and matched with the positioning holes 26. A stopper 24 is fixed to the end of the positioning rod 25. A second elastic member 27 is fixed to the side wall of the stopper 24. The other end of the second elastic member 27 is fixedly connected to the side wall of the second fixing plate 22. When the functional seasoning is dried, the end of the positioning rod 25 is located in the upper positioning hole 26 under the action of the stopper 24 and the second elastic member 27, and the positioning rod 25 can play a role in the second fixing plate 22 through the positioning hole 26. When the functional seasoning is dried, the motor 6 is turned off, and then the positioning rod 25 is moved to the outside of the positioning hole 26 through the stopper 24, and the second fixing plate 22 is moved downward at the same time, so that the second fixing plate 22 drives the transmission rod 10 to move downward. When the second fixing plate 22 moves to a certain extent, the end of the positioning rod 25 automatically enters the interior of the positioning hole 26 below under the action of the stopper 24 and the second elastic member 27, thereby fixing the second fixing plate 22 again. Through the setting of the positioning rod 25 and the two positioning holes 26, the two positions of the second fixing plate 22 can be fixed, thereby effectively improving the stability of the transmission rod 10 when rotating, wherein the second elastic member 27 can be a spring.

[0030] See also Figure 2 and Figure 5 The drying mechanism 3 includes a hot air blower 31 fixed on the top of the bracket 5, an air inlet pipe 34 is installed at the air outlet end of the hot air blower 31, a hollow tube 32 is passed through the top of the drying box 1, and the hollow tube 32 is rotatably connected to the top of the drying box 1, and the lower end of the air inlet pipe 34 extends into the hollow tube 32 and is rotatably connected to the inner wall of the hollow tube 32, and the hollow tube 32 is connected to a plurality of branch pipes 33, and an air outlet is provided at one end of the branch pipe 33 away from the hollow tube 32, wherein the hollow tube 32 is connected to a rotating assembly, and the rotating assembly is used to drive the hollow tube 32 to rotate; When drying the functional seasoning, start the motor 6 and the hot air blower 31. Under the action of the hot air blower 31, the hot air enters the hollow tube 32 through the air inlet pipe 34, and is finally discharged from the air outlet at the end of the branch pipe 33. The functional seasoning inside the drying box 1 is dried by the hot air. In the drying process, the motor 6 drives the transmission rod 10 to rotate through the rotating rod 9 and the adjusting mechanism 2. The transmission rod 10 drives the hollow tube 32 to rotate through the rotating assembly, so that the branch pipe 33 on the side wall of the hollow tube 32 can move in a circle. The circular motion of the branch pipe 33 can stir the functional seasoning inside the drying box 1. To a certain extent, it can stir the functional seasoning, thereby avoiding the agglomeration phenomenon generated during the drying process of the functional seasoning. At the same time, the functional seasoning can be evenly heated, effectively ensuring the drying effect of the functional seasoning.

[0031] See also Figure 3-Figure 5 The rotating assembly includes a first circular gear 35 fixed to the outside of the hollow tube 32, and a second circular gear 36 capable of meshing with the first circular gear 35 is fixed to the outside of the transmission rod 10; When the functional seasoning is dried, the transmission rod 10 rotates and drives the second circular gear 36 to rotate. At this time, the hollow tube 32 can be driven to rotate through the meshing of the second circular gear 36 and the first circular gear 35, so that the branch tube 33 can move in a circle, thereby improving the drying effect of the functional seasoning. When the functional seasoning is dried, the hot air blower 31 and the motor 6 stop working, and then the height of the transmission rod 10 is lowered by the adjustment mechanism 2. On the one hand, the transmission rod 10 can drive the backblowing mechanism 4 to operate after the motor 6 is started, and on the other hand, the first circular gear 35 is disengaged from the meshing of the second circular gear 36, so that the hollow tube 32 cannot rotate.

[0032] See also Figure 6 and Figure 7 The back-blowing mechanism 4 includes a baffle 41 fixedly connected to the inner wall of the air outlet duct 7, and a plurality of air outlet holes 42 are provided on a side of the baffle 41 close to the mesh plate 8. A cavity is provided inside the baffle 41, and the cavity is connected to the plurality of air outlet holes 42. The cavity is connected to a first air pipe 43, and the other end of the first air pipe 43 is connected to an air intake assembly, and the air intake assembly is used to inflate the first air pipe 43; After the functional seasoning is dried, the height of the transmission rod 10 is lowered by adjusting the mechanism 2. At this time, the transmission rod 10 can rotate and inflate the first air pipe 43 through the air intake assembly. The gas enters the cavity inside the baffle 41 through the first air pipe 43, and is finally discharged from the air outlet 42 on the side wall of the baffle 41 and acts on the surface of the mesh plate 8, thereby having a back-blowing effect on the mesh plate 8, and can effectively blow the particulate matter adsorbed on the surface of the mesh plate 8 back into the drying box 1, thereby avoiding waste.

[0033] See also Figure 6 The air intake assembly includes an air pressure cylinder 417 fixedly connected to the outer wall of the air outlet duct 7, the air pressure cylinder 417 is slidably connected to the piston 45 inside, a support rod 46 is fixed to the top of the piston 45, the support rod 46 passes through the top of the air pressure cylinder 417 and is slidably connected to the top of the air pressure cylinder 417, a second air pipe 44 is connected to the side wall of the air pressure cylinder 417, and a one-way valve is provided on the first air pipe 43 and the second air pipe 44, a push plate 48 is fixed to the top of the support rod 46, a third elastic member 47 is fixed to the bottom of the push plate 48, and the bottom of the third elastic member 47 is fixedly connected to the top of the air pressure cylinder 417, wherein an extrusion component is provided above the push plate 48, and the extrusion component is used to extrude the push plate 48; When the transmission rod 10 rotates, the push plate 48 is squeezed by the squeezing component. The push plate 48 drives the piston 45 to move downward through the support rod 46. At this time, under the action of the one-way valve, the external gas enters the air pressure cylinder 417 through the second air pipe 44. When the squeezing component no longer squeezes the push plate 48, the push plate 48 drives the piston 45 to move upward through the support rod 46 under the action of the third elastic member 47. The third elastic member 47 can be a spring. At this time, the piston 45 squeezes the gas above it. Under the action of the one-way valve, the gas enters the cavity inside the baffle 41 through the first air pipe 43, and is finally discharged from the air outlet 42 to achieve a back-blowing effect.

[0034] See also Figure 3 and Figure 4 The extrusion component includes a rotating shaft 410 that passes through the side wall of the bracket 5, and the rotating shaft 410 is rotatably connected to the side wall of the bracket 5. An extrusion block 49 for extruding the push plate 48 is fixed to one end of the rotating shaft 410, and a first bevel gear 411 is fixed to the other end of the rotating shaft 410. A second bevel gear 412 that can mesh with the first bevel gear 411 is fixed to the bottom of the transmission rod 10; When the functional seasoning is dried, the second bevel gear 412 and the first bevel gear 411 at the bottom of the transmission rod 10 are not meshed with the first bevel gear 411. At this time, even if the transmission rod 10 rotates, the transmission rod 10 will not drive the rotating shaft 410 to rotate through the meshing of the first bevel gear 411 and the second bevel gear 412. The back-blowing mechanism 4 does not operate, which can effectively avoid the impact of the back-blowing mechanism 4 on the normal exhaust of the drying box 1. After the functional seasoning is dried, the transmission rod 10 is driven downward by the adjusting mechanism 2, so that the first bevel gear 411 and the second bevel gear 412 are meshed. At this time, the transmission rod 10 rotates and the rotating shaft 410 can be driven to rotate through the meshing of the first bevel gear 411 and the second bevel gear 412. The rotating shaft 410 drives the extrusion block 49 to rotate, and the extrusion block 49 periodically squeezes the push plate 48, so that the air outlet 42 can discharge gas and back-blow the mesh plate 8.

[0035] See also Figure 6 The air outlet duct 7 is provided with a vibration component inside, and the vibration component is used to drive the mesh plate 8 to vibrate back and forth; When the mesh plate 8 is back-blown, the vibrating component inside the air outlet duct 7 will drive the mesh plate 8 to vibrate, thereby accelerating the functional seasoning adsorbed on the surface of the mesh plate 8 to fall off, which can further avoid the functional seasoning being adsorbed on the surface of the mesh plate 8.

[0036] See also Figure 6The vibration component includes a slide bar 415 fixedly connected to the mesh plate 8, the slide bar 415 penetrates the baffle plate 41 and is slidably connected to the baffle plate 41, a fourth elastic member 416 is provided outside the slide bar 415, and both ends of the fourth elastic member 416 are respectively fixedly connected to the mesh plate 8 and the mesh plate 8, a trapezoidal block 414 is fixed to one end of the slide bar 415 away from the mesh plate 8, a push rod 413 is fixed to the bottom of the piston 45, and the lower end of the push rod 413 penetrates the side wall of the air outlet duct 7 and is connected to the inclined surface of the trapezoidal block 414; When the piston 45 moves downward, the piston 45 squeezes the inclined surface of the trapezoidal block 414 through the push rod 413, and the trapezoidal block 414 drives the mesh plate 8 away from the baffle 41 through the slide rod 415. When the piston 45 moves upward, the squeezing degree of the trapezoidal block 414 by the push rod 413 is reduced, and the mesh plate 8 automatically resets under the action of the fourth elastic member 416, thereby approaching the baffle 41. The fourth elastic member 416 can be a spring. This cycle is repeated, so that the mesh plate 8 can vibrate continuously, thereby further avoiding the phenomenon of functional seasoning being adsorbed on the surface of the mesh plate 8. In addition, when the mesh plate 8 is close to the baffle 41, the air outlet 42 will discharge gas to back-blow the mesh plate 8, which can effectively improve the back-blow effect of the back-blow mechanism 4 on the mesh plate 8.

[0037] Working principle: When the device is drying the functional seasoning, the motor 6 and the hot air blower 31 are started. Under the action of the hot air blower 31, the hot air enters the hollow tube 32 through the air inlet pipe 34, and is finally discharged from the air outlet at the end of the branch pipe 33. The functional seasoning inside the drying box 1 is dried by the hot air. During the drying process, the motor 6 drives the rotating rod 9 to rotate, the rotating rod 9 drives the first fixed plate 21 to rotate, the first fixed plate 21 drives the second fixed plate 22 to rotate through the limiting rod 28, the second fixed plate 22 drives the transmission rod 10 to rotate, and the transmission rod 10 drives the hollow tube 32 to rotate through the meshing of the second circular gear 36 and the first circular gear 35, thereby The branch pipe 33 is made to move in a circular motion, and the functional seasoning inside the drying box 1 can be stirred by the circular motion of the branch pipe 33. To a certain extent, the functional seasoning can be stirred, thereby avoiding the agglomeration phenomenon generated during the drying process of the functional seasoning, and at the same time, the functional seasoning can be evenly heated, effectively ensuring the drying effect of the functional seasoning. The side wall of the drying box 1 is connected with an air outlet duct 7, and the air inside the drying box 1 can be smoothly discharged to the outside of the drying box 1 through the air outlet duct 7. At the same time, the mesh plate 8 inside the air outlet duct 7 intercepts the particulate matter in the functional seasoning, thereby preventing the functional seasoning from being dried. The particulate matter inside the functional seasoning is discharged to the outside of the drying box 1, thereby reducing the loss rate and saving costs. When the functional seasoning inside the drying box 1 is dried, the discharge port at the bottom of the drying box 1 is opened, and the motor 6 and the hot air blower 31 are turned off, and then the height of the transmission rod 10 is adjusted so that the first circular gear 35 is disengaged from the meshing of the second circular gear 36, and the first bevel gear 411 is meshed with the second bevel gear 412. When the position of the transmission rod 10 is adjusted, the motor 6 is started again. At this time, the transmission rod 10 can drive the rotating shaft 410 to rotate through the meshing of the first bevel gear 411 and the second bevel gear 412, and the rotating shaft 410 drives the extrusion block 49 rotates, and the extrusion block 49 periodically squeezes the push plate 48. The push plate 48 drives the piston 45 to move downward through the support rod 46. Under the action of the one-way valve, the external gas enters the air pressure cylinder 417 through the second air pipe 44. When the extrusion block 49 no longer squeezes the push plate 48, the push plate 48 drives the piston 45 to move upward through the support rod 46. The piston 45 squeezes the gas above it. Under the action of the one-way valve, the gas enters the cavity inside the baffle 41 through the first air pipe 43, and is finally discharged from the air outlet 42, thereby achieving a back-blowing effect, which can effectively blow the particulate matter adsorbed on the surface of the mesh plate 8 into the drying box 1 again, avoiding waste.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
