[0020] Figure 1-Figure 8 The best embodiment of the present invention is shown below in conjunction with the attached Figure 1-Figure 8 The present invention is further described.

[0022] By means of the above structure: start the vibration motor 5 to move the material from the upper perforated plate 12 and the lower perforated plate 9 toward the discharge hole 13, then connect the air inlet 10 to the hot air inlet, and connect the air outlet 7 to the exhaust pipe, so that the material can be dried during transportation, and the leveling mechanism is started to drive the stirring mechanism to stir the material leaving the upper perforated plate 12 to improve the drying effect. The material has different thickness uniformity after stirring, and after leaving the upper perforated plate 12, it falls onto the lower perforated plate 9. The leveling mechanism cooperates with the vertical plate 8 to flatten the material with different thickness uniformity, so that the material moves on the lower perforated plate 9 with the same thickness, and the thickness of the material can be controlled.

[0023] like Figure 2-Figure 8 As shown, the leveling mechanism includes two mounting plates 28 fixedly mounted on the inner walls on both sides of the fluidized bed body 1, a vertical electric push rod 27 is fixedly mounted on the bottom of one of the mounting plates 28, a cross bar 29 is fixedly mounted on the movable end of the vertical electric push rod 27, a stopper 30 is fixedly mounted on one end of the cross bar 29 away from the vertical electric push rod 27, and the top of the stopper 30 is fixedly connected to the side of the feed hopper 11 through a connecting rod 26.

[0024] A horizontal electric push rod 22 is fixedly installed on the vertical side of another mounting plate 28, and an L-shaped cross bar 23 is fixedly installed on the movable end of the horizontal electric push rod 22. A T-shaped hole is provided on the top of the L-shaped cross bar 23, and a T-shaped track 24 is slidably installed in the T-shaped hole. A rack 20 is fixedly installed on the side of the T-shaped track 24, and L-shaped vertical rods 25 are fixedly installed on the top and bottom of the rack 20. Two positioning holes 17 are provided on the side of the connecting rod 26, and the ends of the two L-shaped vertical rods 25 away from the horizontal electric push rod 22 slide through the two positioning holes 17 respectively.

[0025] The leveling mechanism also includes a gear 14 rotatably mounted on the side of the L-shaped crossbar 23, the gear 14 meshes with the rack 20, an extrusion frame 15 is fixedly mounted on the side of the gear 14, and the extrusion frame 15 is arranged along the radial direction of the gear 14. Limiting blocks 33 are fixedly mounted on the inner walls of both sides of the fluidized bed body 1.

[0026] When it is necessary to dry materials of different thicknesses, the vertical electric push rod 27 can be started in the initial state, and the movable end of the vertical electric push rod 27 drives the cross bar 29 and the stopper 30 to move, and the stopper 30 drives the feed hopper 11 and the discharge frame to move downward through the connecting rod 26, so that the distance between the cross bar 29 and the lower perforated plate 9 and the distance between the discharge frame and the upper perforated plate 12 can be adjusted, and the connecting rod 26 drives the rack 20 to move, and the rack 20 drives the gear 14 to rotate, so that the extrusion frame 15 rotates, and when the cross bar 29 moves downward, the stopper 30 and the lower perforated plate 9 are connected. The spacing of the orifice plate 9 becomes smaller, and the extrusion frame 15 rotates downward, so that when the extrusion frame 15 moves a corresponding distance, the distance that the pressure rod 16 moves downward also increases, so that the distance that the later flattening frame 40 and the U-shaped plate 41 move downward increases, which facilitates the later flattening frame 40 to be level with the bottom of the block 30. Similarly, the cross bar 29 moves upward, and the spacing between the block 30 and the lower orifice plate 9 becomes larger, which will cause the extrusion frame 15 to rotate upward, making the distance that the pressure rod 16 moves downward smaller, which facilitates the later flattening frame 40 to be level with the bottom of the block 30.

[0027] The two limit blocks 33 are provided with limit holes, and the limit rods 34 are slidably installed in the two limit holes. A compression rod 16 is fixedly installed on the side of one of the limit rods 34, and one end of the compression rod 16 extends into the extrusion frame 15. The compression rod 16 is coaxially arranged with the gear 14; the leveling mechanism also includes a flattening frame 40 fixedly installed on the bottom ends of the two limit rods 34, and the side of the flattening frame 40 contacts the side of the block 30. The two sides of the flattening frame 40 and the side close to the vertical plate 8 are provided with movable grooves, and a U-shaped plate 41 is slidably installed in the movable groove. The side of the U-shaped plate 41 away from the block 30 is inclined, that is, the U-shaped plate 41 gradually approaches the vertical plate 8 from top to bottom, and the position of the U-shaped plate 41 corresponds to the vertical plate 8. An extrusion groove 39 is provided on the side close to the flattening frame 40, and the inner wall of the bottom side of the extrusion groove 39 is inclined, that is, the side of the extrusion groove 39 is gradually inclined upward in the direction away from the vertical plate 8; the leveling mechanism also includes a pushing rod 38 fixedly installed on the inner wall of the U-shaped plate 41 close to the stopper 30, and a pushing block 31 is slidably sleeved on the pushing rod 38. The top of the pushing block 31 is fixedly connected to the inner wall of the top side of the flattening frame 40. A return spring 32 is fixedly installed on the side of the pushing block 31 away from the stopper 30. One end of the return spring 32 away from the stopper 30 is fixedly installed on the inner wall of the U-shaped plate 41, and a pressure wheel 37 is rotatably installed on one end of the pushing rod 38 close to the stopper 30, and the pressure wheel 37 corresponds to the position of the extrusion groove 39.

[0028] The L-shaped cross bar 23 drives the T-shaped track 24 and the rack 20 to move, the rack 20 drives the gear 14 and the extrusion frame 15 to move, the inner wall of the extrusion frame 15 squeezes the pressure rod 16, so that the pressure rod 16 moves downward, so that the limit rod 34 moves downward, the limit rod 34 moves downward and drives the flattening frame 40 to move downward, the flattening frame 40 moves and drives the U-shaped plate 41 to move downward, when the bottom of the flattening frame 40 is almost parallel to the bottom of the stopper 30, the pressure wheel 37 and the pressure wheel 37 are in contact with each other. The inclined inner wall of the extrusion groove 39 contacts, thereby squeezing the pressed wheel 37 to move it. The movement of the pressed wheel 37 drives the push rod 38 and the U-shaped plate 41 to move, and the reset spring 32 is deformed. When the U-shaped plate 41 contacts the side of the vertical plate 8, the bottom of the flattening frame 40 is parallel to the bottom of the stopper 30. At this time, the side of the U-shaped plate 41 contacts the side of the vertical plate 8. At this time, the material with uneven thickness that falls onto the lower hole plate 9 can be flattened to make its thickness uniform.

[0029] The two sides of the flattening frame 40, the two sides of the stopper 30 and the two sides of the U-shaped plate 41 are in contact with the inner walls of the fluidized bed body 1. The advantage of this arrangement is that the material is prevented from falling from the two sides of the flattening frame 40, the stopper 30 and the U-shaped plate 41.

[0030] like Figure 4 and Figure 6 As shown, the stirring mechanism includes a guide rod 18 fixedly mounted on the inner walls of both sides of the fluidized bed body 1, a guide sleeve 19 is slidably sleeved on the guide rod 18, a stirring plate 35 is fixedly mounted on the bottom of the guide sleeve 19 through a plurality of cylinders 36, the bottom of the stirring plate 35 is in contact with the top of the upper perforated plate 12, a rotating rod 21 is rotatably mounted on the top of the guide sleeve 19, one end of the rotating rod 21 away from the guide sleeve 19 is rotatably mounted on the bottom of the L-shaped cross bar 23, and there is an angle between the rotating rod 21 and its moving direction to avoid a mechanical dead point. By starting the horizontal electric push rod 22 to make its movable end move back and forth, the L-shaped cross bar 23 first approaches the horizontal electric push rod 22 and then moves back and forth away from the horizontal electric push rod 22. The movement of the L-shaped cross bar 23 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the guide sleeve 19 to move back and forth on the guide rod 18. The movement of the guide sleeve 19 drives the multiple cylinders 36 and the multiple stirring plates 35 to move back and forth, thereby pushing the material that is about to leave the upper perforated plate 12 back and forth, thereby stirring the material.

[0031] like Figure 5 As shown, a discharging frame is fixedly installed at the bottom of the feed hopper 11, and the distance between the bottom of the discharging frame and the top of the upper orifice plate 12 is equal to the distance between the bottom of the stopper 30 and the top of the lower orifice plate 9, and the two sides of the discharging frame are in contact with the inner walls of the fluidized bed body 1. The thickness of the material can be limited by the discharging frame.

[0032] like Figure 8As shown, the lower perforated plate 9 is located below the upper perforated plate 12, and the horizontal distance between the inclined side of the U-shaped plate 41 and the stopper 30 decreases from bottom to top. When the side of the U-shaped plate 41 contacts the side of the vertical plate 8, the material will fall on the inclined side of the U-shaped plate 41, and then after the U-shaped plate 41 moves upward, the material continues to fall without affecting the movement of the material. The inclined inner wall of the extrusion groove 39 increases the horizontal distance from the flattening frame 40 from bottom to top. By setting the extrusion groove 39, the pressed wheel 37 can be squeezed to move.

[0033] like Figure 1 and Figure 3 As shown, a feed pipe 4 is fixedly installed on the top of the fluidized bed body 1, and the bottom end of the feed pipe 4 extends into the fluidized bed body 1 and corresponds to the position of the feed hopper 11. A discharge hole 13 is opened on the inner wall of the fluidized bed body 1 away from the feed pipe 4, and the discharge hole 13 corresponds to the position of the lower perforated plate 9. A discharge pipe 2 is fixedly installed on the vertical side of the fluidized bed body 1, and the discharge pipe 2 corresponds to the position of the discharge hole 13. The discharge hole 13 and the discharge pipe 2 are used for discharging, and the feed pipe 4 is used for feeding.

[0034] The working principle and use process of the present invention are as follows: when in use, material can be fed through the feed pipe 4, and the entered material falls into the feed hopper 11. The material can be introduced into the top of the upper perforated plate 12 through the feed hopper 11 and the discharge frame. The thickness of the material can be limited by the discharge frame. The vibration motor 5 is started to move the material from the upper perforated plate 12 and the lower perforated plate 9 toward the discharge hole 13. Then the air inlet 10 is connected to the hot air inlet, and the air outlet 7 is connected to the exhaust pipe. The material can be dried during transportation.

[0035] When the material is about to leave the upper perforated plate 12, the material is located at the position of multiple stirring plates 35, and the multiple stirring plates 35 and the stopper 30 are close to the vertical plate 8. By starting the horizontal electric push rod 22 to make its movable end move back and forth, the L-shaped cross bar 23 first approaches the horizontal electric push rod 22 and then moves back and forth away from the horizontal electric push rod 22. The movement of the L-shaped cross bar 23 drives the rotating rod 21 to rotate, and the rotation of the rotating rod 21 drives the guide sleeve 19 to move back and forth on the guide rod 18. The movement of the guide sleeve 19 drives the multiple cylinders 36 and the multiple stirring plates 35 to move back and forth, thereby pushing the material that is about to leave the upper perforated plate 12 back and forth, so that the material is stirred. The thickness uniformity of the stirred material is different. After leaving the upper perforated plate 12, it falls onto the lower perforated plate 9.

[0036] During this process, the L-shaped cross bar 23 moves to drive the T-shaped track 24 and the rack 20 to move, the rack 20 moves to drive the gear 14 and the extrusion frame 15 to move, the inner wall of the extrusion frame 15 squeezes the pressure rod 16, so that the pressure rod 16 moves downward, so that the limit rod 34 moves downward, the limit rod 34 moves downward to drive the flattening frame 40 to move downward, the flattening frame 40 moves to drive the U-shaped plate 41 to move downward, when the bottom of the flattening frame 40 is almost parallel to the bottom of the stopper 30, the pressure wheel 37 It contacts the inclined inner wall of the extrusion groove 39, thereby squeezing the pressed wheel 37 to move it. The movement of the pressed wheel 37 drives the push rod 38 and the U-shaped plate 41 to move toward the direction close to the vertical plate 8, and the reset spring 32 is deformed. When the U-shaped plate 41 contacts the side of the vertical plate 8, the bottom of the flattening frame 40 is parallel to the bottom of the stopper 30. At this time, the side of the U-shaped plate 41 contacts the side of the vertical plate 8. At this time, the material with uneven thickness that falls onto the lower hole plate 9 can be flattened to make its thickness uniform.

[0037] Then the L-shaped cross bar 23 moves in the opposite direction, so that the limit rod 34, the U-shaped plate 41 and the flattening frame 40 move upward, and the U-shaped plate 41 returns to its original state under the action of the reset spring 32. The side of the U-shaped plate 41 away from the stop block 30 is inclined. When the side of the U-shaped plate 41 contacts the side of the vertical plate 8, the material will fall on the inclined side of the U-shaped plate 41. Then, after the U-shaped plate 41 moves upward, the reset spring 32 moves the U-shaped plate 41 away from the vertical plate 8, and the material continues to fall without affecting the movement of the material. An elastic pad can be installed on the side of the U-shaped plate 41 close to the vertical plate 8, so that the vertical plate 8 will not be damaged after the U-shaped plate 41 contacts the vertical plate 8.

[0038] When it is necessary to dry materials of different thicknesses, the pressure rod 16 is coaxial with the gear 14 in the initial state, and the vertical electric push rod 27 is started. The movable end of the vertical electric push rod 27 drives the cross bar 29 and the stopper 30 to move. The stopper 30 moves through the connecting rod 26 to drive the feed hopper 11 and the discharge frame to move downward, so that the distance between the cross bar 29 and the lower perforated plate 9 and the distance between the discharge frame and the upper perforated plate 12 can be adjusted. The movement of the stopper 30 drives the connecting rod 26 to move, the movement of the connecting rod 26 drives the rack 20 to move, and the movement of the rack 20 drives the gear 14 to rotate, so that the extrusion frame 15 rotates. When the cross bar 29 moves downward, When the extrusion frame 15 is moved to the left, the distance between the stopper 30 and the lower orifice plate 9 becomes smaller, and the extrusion frame 15 rotates downward, so that when the extrusion frame 15 moves a corresponding distance, the distance that the pressure rod 16 moves downward also increases, so that the distance that the flattening frame 40 and the U-shaped plate 41 move downward in the later stage increases, which is convenient for the flattening frame 40 to be level with the bottom of the stopper 30 in the later stage. Similarly, the cross bar 29 moves upward, and the distance between the stopper 30 and the lower orifice plate 9 becomes larger, which will cause the extrusion frame 15 to rotate upward, so that when the extrusion frame 15 moves, the distance that the pressure rod 16 moves downward becomes smaller, which is convenient for the flattening frame 40 to be level with the bottom of the stopper 30 in the later stage.

[0039] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the above disclosed technical contents to change or modify them into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
