The elastic member facilitates the resetting movement of the threaded block 16.

[0033] In the process of atomizing and cultivating the concrete prefabricated part, the prefabricated part is moved to the support table 5 by the action of the crane, and then the support table 5 and the prefabricated part are moved into the atomization chamber 1 by the action of the slide rail 4, until the sealing plate 6 is attached to the atomization chamber 1 to seal it. Then, the rotating shaft 14 drives the spur gear 13 to rotate through the action of the driving member. The rotation of the spur gear 13 will drive the two sets of rack 12 to move. The movement of the rack 12 will drive the two sets of connecting plate 11 to move, so that the side plate 7 moves away from the support table 5. In this process, the rotation of the rotating shaft 14 will also drive the threaded tube 15 to rotate, so that the threaded block 16 moves through the rotation of the threaded tube 15.

[0034] After the health care is completed, the driving member reversely operates to make the rotating shaft 14 reverse, the reverse of the rotating shaft 14 drives the bevel gear 13 to reverse, thus making the two groups of racks 12 drive the two groups of connecting plates 11 to reversely move, thus the two groups of connecting plates 11 drive the two groups of side plates 7 to move and adhere to the support table 5, at this time, the teeth of the bevel gear 13 will be in the meshing state with the movable teeth 32, in this process, the reverse of the rotating shaft 14 will drive the threaded pipe 15 to reverse, thus making the threaded block 16 drive the connecting pipe 17 to reversely move, and then making the top plate 8 reversely move until adhering to the two side plates 7, in this process, due to the adhesion of the side plates 7, the baffle 10 and the top plate 8, the space of the prefabricated part is separated from the atomization chamber 1, then the slide rail 4 drives the support table 5 to move to move the prefabricated part out of the atomization chamber 1, since the atomization chamber 1 is separated by the baffle 10, the side plate 7 and the top plate 8, the high-temperature steam in the atomization chamber 1 will not leak.

[0036] The elastic member includes a connecting piece 36 rotationally connected with the driving shaft 20, the connecting piece 36 is fixedly connected with a tension spring 37 fixedly connected with the threaded block 16, in the process of the downward movement of the threaded block 16, the tension spring 37 is in tension, thus making the threaded block 16 always closely adhere to the threaded pipe 15, so as to facilitate the rotation of the threaded pipe 15 to drive the threaded block 16 to move again, after the top plate 8 adheres to the side plate 7, the threaded block 16 is just separated from the threaded pipe 15, at this time, the movement of the threaded block 16 pulls the end of the tension spring 37 to move, so that the tension spring 37 is in the tension state.

[0037] Embodiment two: please refer to Figure 6 and Figure 7, the exhaust assembly in the drawing includes an exhaust pipe 21 mounted on the baffle 10, high-temperature steam will be discharged through the exhaust pipe 21, both ends of the exhaust pipe 21 extend to both sides of the baffle 10 respectively, a sealing element is mounted in the exhaust pipe 21, and one end of the exhaust pipe 21 is communicated with a fan cover 22, a through hole 24 is formed in the fan cover 22, and a fan wheel 23 is rotatably connected in the fan cover 22, the fan wheel 23 is connected with a transmission element connected with the rotating shaft 14, the fan wheel 23 rotates through the action of the transmission element, and then the high-temperature steam between the sealed side plate 7 and the top plate 8 is discharged into the atomizing chamber 1.

[0038] The transmission element includes a first bevel gear 25 fixedly connected with the rotating shaft 14, the outer side of the first bevel gear 25 is engaged with a second bevel gear 26, the engagement of the first bevel gear 25 and the second bevel gear 26 achieves the effect of mechanical transmission, the second bevel gear 26 is fixedly connected with a connecting shaft 27 fixedly connected with the fan wheel 23, the fan wheel 23 rotates through the action of the second bevel gear 26, and then wind power is generated to discharge steam, the connecting shaft 27 is rotatably connected with the fan cover 22, and does not affect the normal rotation of the connecting shaft 27, the sealing element includes a support frame 28 fixedly connected with the exhaust pipe 21, a sealing block 29 is slidably connected to the support frame 28, the outer side of the sealing block 29 is sleeved with a sealing ring 30 fixedly connected with the exhaust pipe 21, the exhaust pipe 21 is sealed through the action of the sealing ring 30 and the sealing block 29, so that the high-temperature steam is prevented from flowing reversely into the space between the sealed side plate 7 and the top plate 8, and the first spring 31 is fixedly connected between the sealing block 29 and the support frame 28.

[0039] After the health preservation is completed, when the top plate 8 and the side plate 7 are completely closed, the continued rotation of the rotating shaft 14 caused by the continued rotation of the motor 19 will drive the first bevel gear 25 to rotate, and then the rotation of the first bevel gear 25 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the connecting shaft 27 to rotate, the connecting shaft 27 drives the fan wheel 23 to rotate, and the rotation of the fan wheel 23 sucks the gas in the sealing space of the prefabricated part into the exhaust pipe 21, so that the sealing block 29 in the exhaust pipe 21 moves under the action of the gas, and the sealing block 29 moves to form a gap between the sealing block 29 and the sealing ring 30, so that the steam is discharged into the atomizing chamber 1 through the gap, after a period of exhaust, the motor 19 stops running, at this time, the sealing block 29 is reset due to the action of the spring, and the exhaust pipe 21 is closed again, so that the steam is prevented from flowing reversely into the sealing space of the prefabricated part.

[0040] Example three: please refer to Figure 1 and Figure 8The two groups of connecting plates 11 in the drawing are fixedly connected with the reinforcing plates 38 which are in sliding connection with the rotating shaft 14, which improves the stability of the connecting plates 11 and the rack 12. The top end of the support table 5 is fixedly connected with a plurality of support bars 39, so that there is a gap between the bottom end of the concrete prefabricated part and the top end of the support table 5, which facilitates the atomization of high-temperature steam on the concrete prefabricated part to strengthen its toughness. The sealing plate 6 and the support table 5 are fixedly connected by long bolts.

[0041] The purpose of setting the reinforcing plate 38 is that the connecting plate 11 is long and only one end is connected with the side plate 7. A reinforcing plate 38 which is in sliding connection with the driving shaft 20 is installed on the connecting plate 11, and the reinforcing plate 38 is installed at the other end of the connecting plate 11, which plays a reinforcing role on the connecting plate 11, avoiding the inclination of the connecting plate 11 due to the suspension of the end of the connecting plate 11 away from the side plate 7. A plurality of support bars 39 are set to avoid the whole bottom end of the prefabricated part from being attached to the support table 5, so that the bottom end of the prefabricated part is difficult to contact with the high-temperature steam. Therefore, through the action of the gap, the steam can enter the gap and contact with the bottom end of the prefabricated part. The sealing plate 6 and the support table 5 are fixedly connected by long bolts, so as to facilitate the adjustment of the position of the sealing plate 6, so that the support table 5 can adapt to longer prefabricated parts.

[0042] Working principle: In the process of atomizing and nourishing the concrete prefabricated part, the prefabricated part is moved to the support table 5 by the action of the crane, and then the support table 5 and the prefabricated part are moved into the atomization chamber 1 by the action of the slide rail 4, until the sealing plate 6 is attached to the atomization chamber 1 to seal it. Then the motor 19 is controlled to rotate forward, and the forward rotation of the motor 19 drives the driving shaft 20 to rotate forward, so that the rotating shaft 14 drives the bevel gear 13 to rotate, which drives the two groups of rack 12 to move, and the movement of the rack 12 drives the two groups of connecting plates 11 to drive the two groups of side plates 7 to move, so that the side plates 7 move away from the support table 5. In this process, the rotation of the rotating shaft 14 also drives the threaded pipe 15 to rotate, so that the rotation of the threaded pipe 15 drives the threaded block 16 to move, and the movement of the threaded block 16 drives the connecting pipe 17 to move, so that the top plate 8 moves, and thus the top plate 8 rises away from the prefabricated part. At this time, the atomization chamber 1 is supplied with steam through the action of the air inlet pipe 2 to atomize and nourish the prefabricated part.

[0043] After the health care is completed, the motor 19 is controlled to reverse, so that the driving shaft 20 drives the rotating shaft 14 to reverse, the rotating shaft 14 drives the bevel gear 13 to reverse, so that the two groups of racks 12 drive the two groups of connecting plates 11 to move reversely, so that the two groups of connecting plates 11 drive the two groups of side plates 7 to move and close to the support table 5, at this time, the teeth of the bevel gear 13 will be in meshing state with the movable teeth 32, in this process, the reversing of the rotating shaft 14 will drive the threaded pipe 15 to reverse, so that the threaded block 16 drives the connecting pipe 17 to move reversely, and then the top plate 8 moves reversely until it closes to the side plates 7, after the top plate 8 closes to the side plates 7, the threaded block 16 is just separated from the threaded pipe 15, at this time, the movement of the threaded block 16 pulls the end of the tension spring 37 to move, so that the tension spring 37 is in a stretched state, so that the threaded block 16 is always closely attached to the threaded pipe 15, and then the threaded pipe 15 is restored to normal rotation, so that the threaded pipe 15 can normally drive the threaded block 16 to move upward, in this process, due to the closing effect of the side plates 7, the baffle 10 and the top plate 8, the space existing in the prefabricated part is separated from the atomization chamber 1, then the motor 19 continues to be controlled to reverse, at this time the rotating shaft 14 will continue to drive the bevel gear 13 to reverse, because the bevel gear 13 is in meshing with the movable teeth 32 at this time, the bevel gear 13 will drive the movable teeth 32 to move after meshing with the bevel gear 13, and the movable teeth 32 will compress the second spring 35 so that the movable teeth 32 are separated from the teeth of the bevel gear 13 which are in meshing with them, then the reset action of the second spring 35 makes the movable teeth 32 mesh with another group of teeth on the bevel gear 13 again, the reciprocating movement of the movable teeth 32 realizes the limiting of the rack 12, and then in this state, the rack 12 will not continue to move, so that the position of the side plate 7 is stable, in this process, the rotation of the rotating shaft 14 will also drive the first bevel gear 25 to rotate, and then the rotation of the first bevel gear 25 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the connecting shaft 27 to rotate, the connecting shaft 27 drives the fan 23 to rotate, the rotation of the fan 23 will suck the gas in the sealed space of the prefabricated part into the exhaust pipe 21, so that the movement of the sealing block 29 in the exhaust pipe 21 is realized by the action of the gas, and after the movement of the sealing block 29, a gap is formed between the sealing block 29 and the sealing ring 30, so that the steam will be discharged into the atomization chamber 1 through the gap, after a period of exhaust, the motor 19 stops running, at this time the sealing block 29 is reset due to the action of the spring, and the exhaust pipe 21 is closed again, to avoid the reverse flow of steam into the sealed space of the prefabricated part, then the support table 5 driven by the slide rail 4 moves to move the prefabricated part out of the atomization chamber 1, because the atomization chamber 1 is separated by the baffle 10, the side plate 7 and the top plate 8, so that the high temperature steam in the atomization chamber 1 will not leak.
