The outer surface of the limiting rod 5 is movably sleeved with the inner surface of the movable plate 3.

[0029] A vibration mechanism, the vibration mechanism is arranged on the upper surface of the base plate 1;

[0030] Among them, the vibration mechanism includes a No. 1 motor 6, which is fixedly installed on the inner surface of the rear side of the base plate 1.

The other end of the active rod 8 is hinged with a driven rod 9, and the other end of the driven rod 9 is hinged to the middle part of the upper surface of the moving plate 3. The active rod 8 rotates to make the driven rod 9 drive the moving plate 3 to move forward and backward as a whole.

[0031] When motor No. 1 6 is running, the circular shaft 7 and the active rod 8 will start to rotate. At this time, due to the rotation of the active rod 8, the driven rod 9 will start to rotate. At the same time, the other end of the driven rod 9 will drive the movable plate 3, so that the movable plate 3 as a whole starts to move back and forth along the inner surface of the movable groove 2.

[0032] Among them, a No. 2 motor 10 is fixedly installed on the top of the left surface of the support plate 4, and a rotating rod 11 is fixedly sleeved on the other end of the output shaft of the No. 2 motor 10. The right end of the rotating rod 11 passes through the support plate 4 and extends to the inner side of the support plate 4 and is fixedly connected to a roller 12. A limiting block 30 is fixedly connected to the front side of the outer surface of the roller 12, and a heating plate 31 is fixedly installed inside the roller 12.

[0033] When the second motor 10 is running, the rotating rod 11 and the drum 12 will start to rotate as a whole.

[0034] Among them, a vacuum pump 13 is fixedly installed on the top of the right surface of the support plate 4, and an air outlet 14 is fixedly connected to the right surface of the vacuum pump 13.

The outer surface of the air guide pipe 16 and the inner surface of the drum 12 are movably connected. The air guide pipe 16 and the rotating rod 11 are coaxial.

[0035] The drum 12 as a whole can rotate around the air duct 16 , and the operation of the vacuum extractor 13 causes the air inside the drum 12 to be extracted to the outside of the drum 12 through the air duct 16 , so that the inside of the drum 12 remains in a vacuum state.

[0036] Among them, the bottom end of the drum 12 is movably connected with a closing plate 18, the outer surface of the closing plate 18 is movably connected with a No. 1 bolt 19, the other end of the outer surface of the No. 1 bolt 19 penetrates the closing plate 18 and the drum 12 in sequence and is threadedly sleeved with the inner surface of the drum 12, the upper side of the outer surface of the drum 12 is fixedly connected with a feed port 20, the upper surface of the feed port 20 is movably connected with a cover plate 21, the upper surface of the cover plate 21 is movably connected with a No. 2 bolt 22, the other end of the outer surface of the No. 2 bolt 22 penetrates the cover plate 21 and the feed port 20 in sequence and is threadedly sleeved with the inner surface of the feed port 20.

[0037] The operator can put the material into the drum 12 through the feed port 20 for drying. After drying, the operator removes the closing plate 18 to allow the dried material to slide out of the drum 12, thereby facilitating the collection of the dried material.

[0038] Among them, a cleaning plate 23 is movably connected to the top of the inner cavity of the drum 12, and a push rod 24 is fixedly connected to the upper surface of the cleaning plate 23. The top end of the push rod 24 passes through the drum 12 and extends to the top of the drum 12. The outer surface of the push rod 24 is movably connected to the inner surface of the drum 12.

[0039] When the cleaning plate 23 starts to move downward, the cleaning plate 23 can clean up the residual material dust attached to the inner wall of the drum 12, thereby ensuring that no residual products of the previous drying will remain in the dried material.

[0040] A third motor 27 is fixedly mounted on the top of the front side of the outer surface of the drum 12 , a rotating shaft 28 is fixedly sleeved on the other end of the output shaft of the third motor 27 , and a gear 29 is fixedly sleeved on the outer surface of the rotating shaft 28 .

[0041] When the third motor 27 is running, the rotating shaft 28 and the gear 29 will start to rotate.

[0043] When the gear 29 rotates, the toothed plate 26 starts to move under the limit of the limit block 30 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator uses the closing plate 18 and the No. 1 bolt 19 to close the bottom of the drum 12 and puts the material to be dried into the drum 12 from the feed port 20. Then, the operator uses the cover plate 21 and the No. 2 bolt 22 to close the feed port 20 and start the No. 1 motor 6, the No. 2 motor 10, the vacuum pump 13 and the heating plate 31. The operation of the No. 1 motor 6 will cause the circular shaft 7 and the active rod 8 to start rotating. At this time, the driven rod 9 will start to rotate under the drive of the active rod 8, and the other end of the driven rod 9 will drive the moving plate 3, so that the moving plate 3 as a whole starts to move in the movable groove 2 and the limit rod 5. The roller 12 is subjected to periodic and repeated vibrations under the limit. The operation of the second motor 10 will cause the rotating rod 11 and the roller 12 to start rotating as a whole. The operation of the vacuum pump 13 will extract the air inside the roller 12 through the air duct 16 and the air suction port 15, and discharge it to the outside of the roller 12 along the air outlet 14. The operation of the heating plate 31 will heat the inner wall of the roller 12, so that the moisture in the wet material contacting the inner wall of the roller 12 evaporates rapidly under low pressure and high temperature conditions. Finally, under the joint action of the moving plate 3, the roller 12, the vacuum pump 13 and the heating plate 31, the wet material inside the roller 12 is completely dried.

[0046] At this time, the operator removes the closing plate 18 and takes out the dry material inside the drum 12, and then starts the No. 3 motor 27. As the No. 3 motor 27 runs, the rotating shaft 28 and the gear 29 begin to rotate. Since the outer surfaces of the tooth plate 26 and the gear 29 mesh with each other, the tooth plate 26 as a whole and the cleaning plate 23 begin to move downward along the outer surface of the limit block 30 driven by the meshing of the gear 29. During this process, the cleaning plate 23 cleans the material dust remaining on the inner wall of the drum 12, thereby ensuring that no residual dust inside the drum 12 is mixed into the material to be dried next time.
