[0049] See also Figures 1 to 4 , an embodiment of the present application provides a blanking device, including a flipping mechanism 14, a right side plate 12, a middle plate 13, and a left side plate 11. Among them, the left side plate 11 is arranged on one side of the drying barrel 2. The right side plate 12 is arranged on the other side of the drying barrel 2. The middle plate 13 is arranged between the left side plate 11 and the right side plate 12. Both ends of the flipping mechanism 14 are rotatably arranged in the drying barrel 2, and the flipping mechanism 14 is connected to the bottom of the middle plate 13 so that the middle plate 13 can rotate. A plurality of through holes are provided on the left side plate 11, the right side plate 12 and the middle plate 13, and the left side plate 11 and the right side plate 12 are tilted downward toward the middle plate 13. The edges of the left side plate 11 and the right side plate 12 are tightly fitted with the inner wall of the drying barrel 2, and a gap sufficient for the middle plate 13 to rotate is reserved between the middle plate 13 and the left side plate 11 and the right side plate 12.

[0050] The unloading device 1 provided in an embodiment of the present invention features a plurality of through-holes on the left side panel 11, the right side panel 12, and the middle panel 13. These holes allow the high-temperature air within the drying drum 2 to flow through the holes to the other side of the unloading device 1 (in this embodiment, from the bottom to the top). This improves air circulation within the drying drum 2 and allows the plant material to more fully come into contact with the high-temperature air, enhancing the drying effect. Furthermore, a tilting mechanism 14 is provided at the bottom of the middle panel 13. When drying is complete, the tilting mechanism 14 tilts the middle panel 13 (to an angle of 10°-20°), allowing the material on the middle panel 13 to fall into the lower area in a tilting manner, in conjunction with the vibration effect of the vibration drying device. Furthermore, by tilting both the left and right panels 11, 12 downwardly toward the middle panel 13, when the middle panel 13 is tilted open, the vibration effect of the vibration drying device allows the material on the left and right panels 11, 12 to be unloaded smoothly. This solves the problem of uneven heating and difficult material loading and unloading during plant material drying. The unloading device 1 provided in the embodiment of the present application can be vertically arranged in multiple layers in the drying barrel 2. The material is added from the top layer, and after being dried layer by layer, it is output from the bottom layer, thereby realizing continuous drying to improve the drying efficiency.

[0051] In one embodiment, the flipping mechanism 14 includes a driving unit 145, an inner sleeve 142, a mechanical seal 143, an outer sleeve 144, and a rotating shaft 141. One end of the rotating shaft 141 is rotatably mounted on the drying barrel 2 via a first polytetrafluoroethylene sleeve 146. The inner sleeve 142 is rotatably connected to the other end of the rotating shaft 141 via a second polytetrafluoroethylene sleeve 147; the inner sleeve 142 is connected to the inner wall of the drying barrel 2. The mechanical seal 143 is disposed between the rotating shaft 141 and the inner sleeve 142. The outer sleeve 144 is disposed on the drying barrel 2. The driving unit 145 is disposed on the outer sleeve 144, and the power output end of the driving unit 145 is connected to the rotating shaft 141 to drive the rotating shaft 141 to flip. Polytetrafluoroethylene material is a good anti-friction and self-lubricating material. Its static friction coefficient is smaller than the dynamic friction coefficient. Therefore, it has the advantages of low starting resistance and smooth operation when used to make bearings. In this embodiment, a polytetrafluoroethylene sleeve is used as a bearing to support the rotating shaft 141 , and a mechanical seal 143 is provided between the inner sleeve 142 and the rotating shaft 141 to improve the sealing and heat preservation performance of the drying barrel 2 .

[0052] like Figure 9 As shown, another object of the present invention is to provide a vibration drying system, which adopts the unloading device 1 in any one of the above embodiments, and the vibration drying system includes an exhaust part 5, a vibration source 3 (such as an air hammer, etc.), a hot air source 4, and a drying barrel 2. Among them, multiple unloading devices 1 are vertically distributed in the drying barrel 2, the top of the drying barrel 2 is provided with a feed port 22 and an air outlet, and the bottom of the drying barrel 2 is provided with a discharge port 21 and an air inlet. The vibration source 3 is arranged at the bottom of the drying barrel 2. The output end of the hot air source 4 is connected to the air inlet at the bottom of the drying barrel 2, and the hot air source 4 is used to introduce high-temperature gas into the interior of the drying barrel 2. The input end of the exhaust part 5 is connected to the air outlet at the top of the drying barrel 2, and the exhaust part 5 is used to discharge the humid gas in the drying barrel 2.

[0053] When drying plant materials, the hot air source 4 generates high-temperature gas and inputs it into the drying barrel 2 from the bottom of the air inlet of the drying barrel 2, and then the plant materials enter from the feed port 22 at the top and fall onto the unloading device 1 on the top layer. The high-temperature gas dries the plant materials on the unloading device 1 during the upward movement, and the plant materials are dried layer by layer from top to bottom (in this process, the vibration source 3 generates a vibration effect to facilitate smooth unloading), and finally output from the bottom discharge port 21 of the drying barrel 2, and the humid and low-temperature gas in the drying barrel is discharged outward through the exhaust part 5, keeping the humidity in the drying barrel at a low state.

[0054] In one embodiment, the hot air source 4 includes a blower 41 and a heater 42 . The output end of the blower 41 is connected to the air inlet at the bottom of the drying barrel 2 , and the heater 42 is arranged between the blower 41 and the drying barrel 2 .

[0055] In one embodiment, the exhaust section 5 includes a dust removal device 44 and an induced draft fan 43 . The input end of the induced draft fan 43 is connected to the air outlet at the top of the drying barrel 2 . A dust removal device 44 for dust removal is provided between the induced draft fan 43 and the drying barrel 2 .

[0056] like Figure 5-6 As shown, in one embodiment, the end of the middle plate 13 in the unloading device 1 close to the right side plate 12 is overlapped with the upper surface of the right side plate 12, and a counterweight block 131 is provided at the bottom of the end of the middle plate 13 close to the right side plate 12. The counterweight block 131 is used to automatically reset the middle plate 13 to abut against the right side plate 12 in the absence of other external forces. By providing the counterweight block 131, the weight of the right side of the middle plate 13 is greater than the weight of the left side. When the middle plate 13 is not subjected to the torque force applied by the flipping mechanism 14, the middle plate 13 can automatically reset to abut against the right side plate 12 under the action of the gravity of the counterweight block 131. As a result, after the unloading device 1 completes a tilting and unloading, it can automatically return to its original position to receive materials falling from above.

[0057] like Figure 7-8 As shown, in one embodiment, the multiple unloading devices 1 on the drying drum 2 are driven and controlled by a single drive unit 145, which includes multiple horizontal gears 1454, a control spindle 1452, multiple vertical gears 1453, and a servo motor 1451. The control spindle 1452 is connected to the power output of the servo motor 1451, with a speed reducer interposed between the servo motor 1451 and the control spindle 1452. Vertical gears 1453 are disposed at the ends of the rotating shafts 141 within the tilting mechanism 14, with each end of the rotating shaft 141 being provided with a vertical gear 1453. The horizontal gears 1454 are all arranged on the control main shaft 1452, and the horizontal gears 1454 are meshed with the vertical gears 1453 one by one; the horizontal gears 1454 include a toothed portion 14541 and a toothless portion, and the toothed portion 14541 of the horizontal gear 1454 is meshed with the vertical gear 1453, and during the rotation of the horizontal gear 1454, the toothed portion 14541 of each horizontal gear 1454 does not overlap, and in a bottom-to-top order, the vertical gears 1453 are meshed with the toothed portion 14541 of the corresponding horizontal gear 1454 in turn.

[0058] By installing multiple horizontal gears 1454 on the same control main shaft 1452 in order from bottom to top, they are engaged with the corresponding vertical gears 1453 in turn (when engaged, the rotating shaft 141 in the flipping mechanism 14 is driven to rotate, thereby causing the middle plate 13 to perform an inclined unloading action), and during the rotation of the horizontal gears 1454, the toothed parts 14541 of each horizontal gear 1454 do not overlap, thereby making the timing of rotation of each vertical gear 1453 different (that is, the actions of dumping materials by different unloading devices 1 will not occur at the same time).

[0059] Then, when the driving part 145 controls the unloading device 1, first the toothed portion 14541 of the bottom horizontal gear 1454 engages with the bottom vertical gear 1453. At this time, the driving part 145 controls the bottom flipping mechanism 14 to operate, thereby causing the middle plate 13 in the bottom unloading device 1 to rotate a certain angle (the specific value of the angle can be achieved by controlling the number of teeth of the toothed portion 14541 on the horizontal gear 1454 to control the single rotation angle of the vertical gear 1453, thereby controlling the rotation angle of the middle plate 13) to perform dumping and unloading. The material that has been dried on the unloading device 1 at the lowest level is dumped to the bottom of the drying barrel 2 and output from the discharge port 21 at the bottom of the drying barrel 2. After the material is dumped, the lowest horizontal gear 1454 is always rotating, so that the lowest vertical gear 1453 is disengaged from the toothed part 14541 of the horizontal gear 1454. At this time, under the action of the counterweight block 131 of the middle plate 13, the middle plate 13 rotates in the opposite direction until the right side is overlapped on the right side plate 12 to achieve reset, so as to receive the falling material from the upper unloading device 1. When the control spindle 1452 continues to rotate until the toothed portion 14541 of the second-to-last horizontal gear 1454 at the bottom meshes with the vertical gear 1453 at the corresponding position (i.e., the second-to-last vertical gear 1453 at the bottom), the second bottom unloading device 1, under the control of the drive unit 145, performs the unloading action described above, thereby dumping the material on the second bottom unloading device 1 onto the bottom-most unloading device 1 below for further drying. Therefore, the drive unit 145 in this embodiment unloads the material from the unloading devices 1 sequentially from bottom to top, thereby achieving continuous and orderly unloading and improving drying efficiency. Furthermore, mixing of materials is less likely to occur (e.g., if material is not dried within a certain layer of unloading device 1 and is directly unloaded by the unloading device 1 to the next layer, resulting in incomplete drying), ensuring that all materials are fully dried.

[0060] When the control spindle 1452 rotates one circle until the toothed portion 14541 on the horizontal gear 1454 again meshes with the corresponding vertical gear 1453, the unloading device 1 tilts again to unload the material. Therefore, by controlling the rotational speed of the control spindle 1452, the interval between the two unloading actions of the unloading device 1 can be controlled, thereby controlling the drying time of the material on each layer of the unloading device 1. Specifically, when it is necessary to dry the material on each layer of the unloading device 1 for a longer time, a speed reducer can be added between the servo motor 1451 and the control spindle 1452 to reduce the rotational speed of the control spindle 1452, or the rotational speed of the servo motor 1451 can be directly reduced. Conversely, the drying time of the material on each layer of the unloading device 1 can be shortened.

[0061] The driving part 145 provided in this embodiment has a simple structure and does not have other complex structures such as timer sensors. It only controls the multi-layer unloading device 1 in the drying box to circulate the unloading from bottom to top through a simple gear meshing transmission structure, and ensures that there is no mixing of materials that leads to incomplete drying of the materials, thereby improving the drying efficiency and effect. In addition, the drying time of the materials on each layer of the unloading device 1 can be directly controlled by controlling the rotation speed of the driving part 145.

[0062] See also Figure 5-6 In one embodiment, an elastic buffer structure 121 is provided at the contact point between the right side panel 12 and the middle panel 13. The elastic buffer structure 121 can be a spring, a spring, or a resilient cavity provided on the upper surface of the right side panel 12 at the contact point between the middle panel 13 and the right side panel 12. The elastic buffer structure 121 significantly cushions the impact when the middle panel 13 collides with the right side panel 12 due to the weight of the counterweight 131. This protects both the middle panel 13 and the right side panel 12.

[0063] In one embodiment, the side of the middle plate 13 proximal to the left plate 11 abuts against the bottom of the left plate 11, and a magnetic structure 111 is provided at the abutment position between the left plate 11 and the middle plate 13. The magnetic structure 111 is used to improve the stability of the middle plate 13 when it is in the reset state. The magnetic structure 111 can cause the middle plate 13 to be attracted to the left plate 11, improving the stability of the middle plate 13 in the reset state, so as to facilitate receiving the material output by the upper unloading device 1 and prevent the middle plate 13 from opening and leaking due to the impact of the upper material.

[0064] The above are only preferred embodiments of the present invention and are 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 scope of protection of the present invention.
