The control motor is arranged on the support frame 12, and the output shaft of the control motor is connected to the control shaft 31, so that the first control rod 32 and the second control rod 33 can be driven to rotate by the control motor, and the second control rod 33 slides on the first control rod 32, so as to facilitate the adjustment of the angle of the drying drum 13.

[0034] Reference Figures 1 to 8 A driving assembly 4 is provided on the mounting frame 11. The driving assembly 4 is used to drive the drying drum 13 to rotate. The driving assembly 4 includes a driving ring gear 41 fixed on the drying drum 13, a driving gear 42 rotatably connected to the support frame 12, and a driving motor 43 fixed on the support frame 12. The driving ring gear 41 is meshed with the driving gear 42, and the output shaft of the driving motor 43 is connected to the driving gear 42. The driving motor 43 rotates, thereby driving the driving gear 42 to rotate, thereby driving the drying drum 13 to rotate.

[0035] Reference Figures 1 to 8 The cleaning assembly 5 is provided in the drying cylinder 13, and the cleaning assembly 5 is used to clean the machine-made sand attached to the drying cylinder 13. The cleaning assembly 5 includes a cleaning belt 51 slidably connected to the drying cylinder 13, a reel 52 and a winding roller 53 rotatably connected to the outer wall of the drying cylinder 13. At the same time, a clearance groove 10 is opened on the drying cylinder 13, and the cleaning belt 51 is attached to the inner wall of the drying cylinder 13, and the two ends of the cleaning belt 51 extend out of the clearance groove 10 from the interior of the drying cylinder 13, and one end of the cleaning belt 51 is fixed on the winding roller 53, and the other end is fixed on the unwinding roller 52. In addition, a rotating motor is fixedly installed on the outer wall of the drying cylinder 13, and two rotating motors are provided, one transfer motor is connected to the winding roller 53, and the other rotating motor is connected to the unwinding roller 52, so that the cleaning belt 51 can be wound around the winding roller 53 or the unwinding roller 52 through the rotation of the winding roller 53.

[0036] Reference Figures 1 to 8A plugging component 6 is arranged in the give way groove 10, and the plugging component 6 is used to plug the give way groove 10, thereby preventing the machine-made sand from flowing out of the drying cylinder 13 from the give way groove 10. The plugging component 6 includes a plugging piece 61 connected to the surface of the cleaning belt 51 and an elastic connecting part 62 arranged on the plugging piece 61. Two plugging pieces 61 are arranged, and the two plugging pieces 61 are connected by the elastic connecting part 62. The plugging piece 61 and the elastic connecting part 62 surround a sealed cavity. At the same time, an inflation component is arranged on the drying cylinder 13. The inflation component can be set as an inflation pump, and the sealed cavity is inflated through the inflation component. At the same time, the gas in the sealed cavity can be discharged, so that the elastic connecting part 62 between the two sealing pieces 61 can be deformed to move. At this time, the entire sealing assembly 6 can vibrate, and then it is convenient to clean the machine-made sand on the sealing assembly 6. Since the sealing piece 61 abuts against the surface of the cleaning belt 51, the machine-made sand on the surface of the cleaning belt 51 can be scraped when the cleaning belt 51 rotates. The cleaning belt 51 after cleaning will be wound around the winding roller 53 or the unwinding roller 52. At the same time, the cleaning belt 51 without machine-made sand attached will also rotate to the inner wall of the drying cylinder 13, so as to achieve the purpose of facilitating the cleaning of the inner wall of the drying cylinder 13.

[0037] Reference Figures 1 to 8 After the cleaning belt 51 on the winding roller 53 is unwound, the cleaning belt 51 on the unwinding roller 52 can be unwound. At the same time, the control component 3 drives the support frame 12 and the drying drum 13 rotating on the support frame 12 to rotate, so that the drying drum 13 is tilted, thereby facilitating the machine-made sand in the drying drum 13 to fall onto the conveying component 2.

[0038] Reference Figures 1 to 8The conveying assembly 2 includes a driving roller 21 rotatably connected to the mounting frame 11, a first moving roller 22 and a second moving roller, and a conveyor belt 24 wound around the first moving roller 22 and the driving roller 21. The rotation of the driving roller 21 can drive the conveyor belt 24 to rotate. In the initial state, the conveyor belt 24 and the first moving roller 22 are both in the drying drum 13, and then the first moving roller 22 and the second moving roller are both slidably connected to the mounting frame 11. At the same time, a driving member 20 is arranged on the mounting frame 11. In this embodiment, the driving member 20 is arranged to be a driving cylinder, which can drive the second moving roller to rotate. In this embodiment, the conveyor belt 24 is set to be a non-elastic material. In addition, a support assembly 8 is provided on the mounting frame 11. The position of the first movable roller 22 is supported by the support assembly 8. Then, when the driving cylinder drives the second movable roller to move, the second movable roller will pull the conveyor belt 24 to move, and then the conveyor belt 24 will drive the first movable roller 22 to move, thereby moving the first movable roller 22 out of the drying cylinder 13, and at the same time, the conveyor belt 24 between the first movable roller 22 and the second movable roller is tilted. At this time, the inclined conveyor belt 24 is below the drying cylinder 13. Then, after the drying cylinder 13 is tilted, it is convenient for the machine-made sand in the drying cylinder 13 to fall onto the conveyor belt 24, and then be sent to the weighing assembly 60 through the inclined conveyor belt 24.

[0039] Reference Figures 1 to 8 The second moving roller is rotatably connected with the mounting shaft 30, and the mounting shaft 30 is fixedly provided with a sliding block 40. One end of the driving cylinder is hinged on the sliding block 40, and the other end is hinged on the mounting frame 11. At the same time, a limiting groove 7 is provided on the mounting frame 11. The limiting groove 7 includes a vertically arranged first limiting portion 71 and an inclinedly arranged second limiting portion 72. The first limiting portion 71 and the second limiting portion 72 are connected, and the mounting shaft 30 is slidably connected in the limiting groove 7. The driving cylinder retracts, driving the second limiting roller to move, and the conveyor belt 24 drives the first moving roller 22 to move. Under the action of the first limiting portion 71 and the second limiting portion 72, the conveyor belt 24 between the first moving roller 22 and the second moving roller is tilted, and the inclined conveyor belt 24 is located outside the drying drum 13, and the inclined conveyor belt is located below the drying drum 13.

[0040] Reference Figures 1 to 8The support assembly 8 includes a support block 81 rotatably connected to the first moving roller 22, a support rod 82 fixed on the support block 81, and a support spring 83 sleeved on the support rod 82. The support rod 82 is slidably connected to the mounting frame 11. One end of the support spring 83 is fixed on the mounting frame 11, and the other end is fixed on the support rod 82. When the second moving roller moves, it will drive the first moving roller 22 to move. When the first moving roller 22 moves, it will drive the support rod 82 to slide on the mounting frame 11. At this time, the support spring 83 will be compressed, and then when the second moving roller moves in the opposite direction, the support spring 83 will push the support rod 82 to move in the opposite direction, and then the conveyor belt 24 and the first moving roller 22 will move into the drying cylinder 13, thereby facilitating the subsequent transportation of the undried machine-made sand into the drying cylinder 13, which is more convenient for the subsequent weighing of the machine-made sand.

[0041] Reference Figures 1 to 8 One end of the drying cylinder 13 is provided with an opening 50 for conveying the weighed machine-made sand into the drying cylinder 13. The drying cylinder 13 is provided with a sealing assembly 9 for sealing the opening 50 on the drying cylinder 13. The sealing assembly 9 includes a sealing shaft 91 rotatably connected to the drying cylinder 13, a sealing plate 92 fixed on the sealing shaft 91, and a sealing motor for driving the sealing shaft 91 to rotate. When the machine-made sand is conveyed to the drying cylinder 13, the sealing motor drives the sealing shaft 91 to rotate, and then drives the sealing plate 92 to rotate through the sealing shaft 91, and blocks the opening 50 of the drying cylinder 13 through the sealing plate 92. Finally, when the drying cylinder 13 rotates, the machine-made sand can be prevented from spilling out of the opening 50 of the drying cylinder 13.

[0042] Reference Figures 1 to 8 A limit plate 01 is arranged on the mounting frame 11, and two limit plates 01 are arranged. The two limit plates 01 are arranged on both sides of the conveyor belt 24, so that when the conveyor belt 24 conveys the machine-made sand, the machine-made sand on the conveyor belt 24 can be reduced from being separated. The limit plate 01 is slidably connected with an abutment plate 02 for extending into the drying cylinder 13. The limit plate 01 is provided with a push spring 03 for pushing the abutment plate 02 to extend into the drying cylinder 13. One end of the push spring 03 is fixed on the limit plate 01, and the other end is fixed on the abutment plate 02. On the plate 02, when the first moving roller 22 moves out of the drying cylinder 13, the sealing plate 92 rotates. When the sealing plate 92 rotates, it will push the abutment plate 02 to move from the inside of the drying cylinder 13 to the outside of the drying cylinder 13. At this time, the pushing spring 03 is compressed, and then the drying cylinder 13 is rotated to a horizontal state, and when it is necessary to transport the machine-made sand into the drying cylinder 13, the sealing motor drives the sealing plate 92 to rotate, and then the pushing spring 03 pushes the abutment plate 02 to move into the drying cylinder 13, and the transported machine-made sand is limited at this time.

[0043] The implementation principle of an online detection device for machine-made sand in the embodiment of the present application is as follows: first, undried machine-made sand is placed on the weighing assembly 60 for weighing. After weighing, the machine-made sand is transported to the drying drum 13 through the conveyor belt 24. Then, the second moving roller is driven to move by the driving cylinder. At this time, the first moving roller 22 is moved out from the inside of the drying drum 13, so that the conveyor belt 24 between the first moving roller 22 and the second moving roller is tilted, and the tilted conveyor belt 24 is located below the drying. In addition, the opening 50 of the drying drum 13 is sealed by the sealing plate 92. After the sealing of the drying drum 13 is completed, the driving assembly 4 drives the drying drum 13 to rotate. At this time, The machine-made sand in the drying cylinder 13 is dried faster. After the drying is completed, the drying cylinder 13 is driven to be tilted through the control component 3. At this time, the opening 50 of the drying cylinder 13 is opened, and the machine-made sand in the drying cylinder 13 will fall onto the inclined conveyor belt 24 under the action of gravity. At the same time, the winding roller 53 and the unwinding roller 52 are rotated, and then the machine-made sand on the cleaning belt 51 is cleaned under the action of the blocking piece 61. The cleaned machine-made sand will also fall onto the conveyor belt 24 under the action of gravity. On the one hand, it can reduce the detection error, and on the other hand, it can facilitate the cleaning of the machine-made sand attached to the inner wall of the drying cylinder 13, so as to facilitate the subsequent drying of the subsequent machine-made sand.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
