[0047] During the recovery operation, the fixed hanger 309 is lowered by the second electric telescopic rod 406 so that the suction head 307 can be close to the mixture. When the suction mechanism 3 rotates, the rotary joint 402 will also rotate accordingly without affecting the transportation of the mixture.

[0048] Embodiment 2:

[0049] See also Figure 1 , Figure 2 , Figure 5 and Figure 7 A re-drum mechanism 7 is provided at the top of the separation drum 6, a telescopic bottom pipe 601 is fixedly provided at the bottom end of the separation drum 6, and the telescopic bottom pipe 601 is fixedly provided at the bottom end of the recovery tank 5 through a bottom connecting frame 605, a first concrete conveying pipe 602 is fixedly provided at the other end of the telescopic bottom pipe 601, a second vacuum pump 603 is fixedly provided at the other end of the first concrete conveying pipe 602, a second concrete conveying pipe 604 is fixedly provided at the output end of the second vacuum pump 603, and the second concrete conveying pipe 604 is externally connected to a concrete recovery device, a first mud conveying pipe 503 is fixedly provided at the bottom end of the recovery tank 5, a first vacuum pump 504 is fixedly provided at the other end of the first mud conveying pipe 503, a second mud conveying pipe 505 is fixedly provided at the output end of the first vacuum pump 504, and the second mud conveying pipe 505 is externally connected to a mud treatment pool.

[0050] The separated concrete particles will enter the first concrete conveying pipe 602 from the telescopic bottom pipe 601, and will be input into the concrete recovery device through the second vacuum pump 603 and the second concrete conveying pipe 604. The setting of the telescopic bottom pipe 601 is convenient for adapting to the height change of the separation cylinder 6, and will not affect the conveying effect of the concrete particles. The separated mud will be input into the mud treatment pool through the first mud conveying pipe 503, the first vacuum pump 504 and the second mud conveying pipe 505, so as to achieve the recovery effect and save resource consumption.

[0051] For further information, see Figure 1 The double-drum mechanism 7 includes a circular moving side frame 701, which is symmetrically arranged at the top of the separation drum 6. A cross-connecting plate 7011 is fixedly arranged between the circular moving side frames 701. A reset spring 702 and a connecting slide column 703 are fixedly arranged at the top of the cross-connecting plate 7011. A connecting sleeve 704 is slidably arranged on the outer side of the connecting slide column 703. A second motor 705 is arranged at the other end of the connecting sleeve 704. The connecting sleeve 704 is fixedly arranged at the driving end of the second motor 705. The reset spring 702 is fixedly arranged at the other end of the connecting sleeve 704. The cross-connecting plate 7011 is detachably arranged at the top of the separation drum 6. The second motor 705 is fixedly arranged at the top of the side-connected fixed frame 501. The driving end of the second motor 705 passes through and is rotatably arranged at the top of the side-connected fixed frame 501.

[0052] During separation, the second motor 705 is started, and the second motor 705 drives the connecting sleeve 704, the connecting sliding column 703 and the cross-connecting plate 7011 to rotate. The cross-connecting plate 7011 will drive the two circularly movable side frames 701 to move around, and at the same time drive the separation cylinder 6 to rotate, wherein the mud in the mixture will be thrown out from the sieve holes by centrifugal force and adhere to the inner wall of the recovery tank 5, thereby achieving the effect of separating the mixture, and due to the effect of gravity, the concrete particles will sink to the inner bottom of the separation cylinder 6, and the mud on the inner wall of the recovery tank 5 will slide to the inner bottom of the recovery tank 5, so that it can be transported.

[0053] See also Figure 1 , Figure 2 A limiting frame 706 is detachably provided inside one side of the ring-moving side frame 701, an auxiliary spring 707 is fixedly provided inside one side of the ring-moving side frame 701, a ring-moving block 708 is fixedly provided at the other end of the auxiliary spring 707, a tank outer slide rail 709 is slidably provided at the bottom end of the ring-moving block 708, the tank outer slide rail 709 is fixedly provided on the outside of the recovery tank 5, and one side of the bottom end of the ring-moving side frame 701 is convex.

[0054] Among them, the circumferential side frame 701 will contact the protrusion 5012 while performing a circumferential movement. Every time the circumferential side frame 701 moves around a circle, the circumferential side frame 701 will contact the two protrusions 5012. Therefore, the circumferential side frame 701 will rise and fall twice, and drive the separation cylinder 6 to rise. At this time, the reset spring 702 and the auxiliary spring 707 will extend, and the limit frame 706 will also rise with it. When the circumferential side frame 701 leaves the protrusion 5012, the limit frame 706 falls and contacts the circumferential connecting block 708 to prevent excessive descent, so that the separation cylinder 6 can shake up and down, preventing the concrete in the separation cylinder 6 from clogging the telescopic bottom pipe 601.

[0055] See also Figure 1 , Figure 2 The outer side of the recovery tank 5 is symmetrically and detachably provided with a support leg 502, the outer side of the recovery tank 5 is detachably provided with a side fixed frame 501, a fixed block frame 5011 is detachably provided between the recovery tank 5 and the side fixed frame 501, a protrusion 5012 is fixedly provided at the top of the fixed block frame 5011, and the fixed block frame 5011 and the protrusion 5012 are symmetrically arranged on the outer side of the recovery tank 5.

[0056] The fixed block frame 5011 is used to support the use of the protrusion 5012. The protrusion 5012 can generate two lifting forces for each rotation of the separation cylinder 6, thereby providing shaking force for the shaking of the separation cylinder 6.

[0057] See also Figure 1 , Figure 2An auxiliary drive assembly 8 is provided at the top of the recovery tank 5 and the separation cylinder 6, and the auxiliary drive assembly 8 includes a connecting bracket 801, and the connecting bracket 801 is detachably arranged at the top of the separation cylinder 6, and a connecting spring frame 802 is fixedly arranged on the inner side of the top of the connecting bracket 801, and bearing seats 803 are slidably arranged on both sides of the connecting spring frame 802, and an appropriate distance spring 804 is fixedly arranged between the connecting spring frame 802 and the bearing seat 803, and a sliding block 805 is fixedly arranged at the bottom end of the appropriate distance spring 804, and a tank top slide rail 808 is slidably arranged at the bottom end of the sliding block 805, and an inner wall scraper 806 is detachably arranged on one side of the sliding block 805, and the inner wall scraper 806 is spirally arranged, and a mud pusher 807 is fixedly arranged on one side of the bottom end of the inner wall scraper 806.

[0058] When the separation cylinder 6 rises, it drives the connecting bracket 801 and the connecting spring frame 802 in the auxiliary drive assembly 8 to rise, and the appropriate distance spring 804 will extend. When the separation cylinder 6 rotates, it can drive the connecting bracket 801, the connecting spring frame 802, the sliding block 805, the inner wall scraper 806 and the mud pushing plate 807 to move in a circle. The setting of the connecting spring frame 802, the bearing seat 803 and the appropriate distance spring 804 makes it possible to drive the inner wall scraper 806 and the mud pushing plate 807 to move when the height of the separation cylinder 6 changes. The inner wall scraper 806 moves along the inner wall of the recovery tank 5, thereby scraping off the mud, and sliding down along the trajectory of the inner wall scraper 806 to reach the inner bottom of the recovery tank 5, and pushing the mud into the output port through the mud pushing plate 807, and transporting it to the mud treatment pool through the first mud conveying pipe 503, the first vacuum pump 504 and the second mud conveying pipe 505 for easy recycling.

[0059] Embodiment three:

[0060] A vacuum conveying method for bored pile top mixture comprises the following steps:

[0061] S1, assembling the bearing plate 2 and placing it around the pile hole to block the mixture and facilitate the centralized recovery of the mixture;

[0062] S2, then start the recovery vacuum pump 4 to start the suction work, the mixture will enter the suction telescopic tube 306, the connecting delivery tube 308 and the rotary joint 402 from the suction head 307, and enter the separation cylinder 6 through the delivery main tube 401, and at the same time start the first motor 203 to rotate the driving gear 204, and the driving gear 204 drives the suction mechanism 3 to rotate. Since grouting work is required, the maximum rotation angle of the suction mechanism 3 is 165 degrees to prevent the suction mechanism 3 from contacting the grouting pipe, so that the mixture can be fully recovered;

[0063] S3. If the diameter of the pile hole is small, the first electric telescopic rod 303 in the suction mechanism 3 is activated so that the connecting frame 304 can drive the suction telescopic tube 306 to move back and forth horizontally, thereby making the suction head 307 have a larger suction area, which is convenient for conveying more mixture;

[0064] S4, the sucked mixture enters the separation drum 6, and the separation drum 6 is rotated under the driving of the second motor 705, and the mud is separated by centrifugal force, and the mud enters the recovery tank 5, and the concrete particles remain in the separation drum 6, thereby completing the separation work;

[0065] S5. When the separation drum 6 rotates, the circular side frame 701 will contact the protrusion 5012 and make the separation drum 6 rise, and then the separation drum 6 falls back to the initial height, so that the concrete particles in the separation drum 6 can be shaken to prevent the telescopic bottom pipe 601 from being blocked, thereby facilitating the transportation work.

[0066] Working principle: put the two bearing plates 2 and the bottom plate 201 close to each other, then fix them with bolts and place them around the pile hole. When recovering the mixture, first turn on the recovery vacuum pump 4, then start the second electric telescopic rod 406, so that the fixed hanger 309 can drive the other end of the suction telescopic tube 306 and the suction head 307 to descend, so as to facilitate the suction of the mixture. If the diameter of the pile hole is small, the first electric telescopic rod 303 can be started, so that the connecting frame 304 can drive the sliding hanger 305 and the suction telescopic tube 306 and the suction head 307 to move back and forth horizontally, so as to have a larger suction area. While performing the suction work, start the first motor 203 to rotate the driving gear 204. The rotation of the driving gear 204 drives the linkage gear ring 302 to rotate, so that the water droplet suction mechanism 3 can perform suction work around the pile hole, thereby improving the suction and transportation efficiency of the mixture and preventing pollution of the surrounding environment.

[0067] The mixture can enter the rotary joint 402 through the suction telescopic tube 306 and the connecting conveying tube 308 through the recovery vacuum pump 4, and then enter the conveying main tube 401, and enter the separation cylinder 6 through the conveying of the conveying main tube 401. The outer part of the separation cylinder 6 is provided with a plurality of sieve holes, which is convenient for separating the mud and concrete particles in the mixture. At this time, the second motor 705 in the double-cylinder mechanism 7 is started, and the second motor 705 drives the connecting sleeve 704, the connecting sliding column 703 and the cross-connecting plate 7011 to rotate. The cross-connecting plate 7011 will drive the two circular side frames 701 to move around, and at the same time drive the separation cylinder 6 to rotate, wherein the mud in the mixture will be thrown out from the sieve holes by centrifugal force and adhere to the inner wall of the recovery tank 5, thereby achieving the effect of separating the mixture;

[0068] The side frame 701 moves in a circular motion and contacts with the two protrusions 5012. Each time the side frame 701 moves in a circular motion, the side frame 701 contacts with the two protrusions 5012. Therefore, the side frame 701 rises and falls twice and drives the separation drum 6 to rise. At this time, the return spring 702 and the auxiliary spring 707 extend, and the limit frame 706 also rises accordingly. When the side frame 701 leaves the protrusion 5012, the limit frame 706 falls and contacts with the circular transfer block 708 to prevent excessive falling, so that the separation drum 6 can shake up and down, preventing the concrete in the separation drum 6 from clogging the telescopic bottom pipe 601, thereby improving the recovery and transportation efficiency. The concrete can be transported into the concrete recovery device through the first concrete delivery pipe 602, the second vacuum pump 603 and the second concrete delivery pipe 604 for recycling and utilization, thereby reducing resource waste.

[0069] When the separation cylinder 6 rises, it drives the connecting bracket 801 and the connecting spring frame 802 in the auxiliary drive assembly 8 to rise, and the appropriate distance spring 804 will extend. When the separation cylinder 6 rotates, it can drive the connecting bracket 801, the connecting spring frame 802, the sliding block 805, the inner wall scraper 806 and the mud pushing plate 807 to move in a circle. The setting of the connecting spring frame 802, the bearing seat 803 and the appropriate distance spring 804 makes it possible to drive the inner wall scraper 806 and the mud pushing plate 807 to move when the height of the separation cylinder 6 changes. The inner wall scraper 806 moves along the inner wall of the recovery tank 5, thereby scraping off the mud, and sliding down along the trajectory of the inner wall scraper 806 to reach the inner bottom of the recovery tank 5, and pushing the mud into the output port through the mud pushing plate 807, and transporting it to the mud treatment pool through the first mud conveying pipe 503, the first vacuum pump 504 and the second mud conveying pipe 505 for easy recycling.
