the output end of the conveying and collecting device 10 is connected to the feed end of the transfer processing device 30, and the conveying and collecting device 10 is used for collecting the pretreated concrete to the transfer processing device 30.
Based on the existing structure of the concrete pouring system, the concrete pouring mode of the embodiment of the invention is as follows: the pre-treated concrete is collected into the transfer processing device 30 by the conveying and collecting device 10, the transfer processing device 30 receives a certain amount of concrete and then throws the certain amount of concrete into the integral casting machine 20 at a time, the integral casting machine 20 casts the certain amount of concrete to the construction ground, and the conveying and collecting device 10 and the transfer processing device 30 cooperate to form an intermittent quantitative delivery mode so as to realize the quantitative casting of the integral casting machine 20 and keep the concrete casting amount of each casting ground consistent.
The conveying and collecting device 10 comprises a concrete pump truck 11, a conveying pipe 12 and a collecting tank 13, one end of the conveying pipe 12 is connected with a discharge hole of the concrete pump truck 11, the other end of the conveying pipe 12 is connected with an expansion bend 14, the expansion bend 14 is connected with an inlet of the collecting tank 13 through a plurality of material distributing pipes 15, and a stirring assembly 16 used for turning received concrete is arranged in the collecting tank 13.
The design of the expansion bend 14 is based on the fact that during the concrete blanking process, due to the long length of the conveying pipe 12, the concrete can be deposited in the conveying pipe and cannot be conveyed downwards, and the purpose of the expansion bend 14 is to design the expansion bend into a special station, and then the concrete is conveyed downwards continuously through a plurality of distributing pipes 15, so that the possibility of concrete accumulation is reduced.
In addition, the design purpose of the stirring assembly 16 is based on the composition components with different particle sizes in the concrete, in the gravity blanking process, large particles are below in the process of being sent into the collecting tank 13, and smaller particles are above, so that the uniformity of the concrete is different, and therefore one more stirring assembly 16 is arranged to perform secondary stirring on the concrete.
Specifically, as shown in fig. 2, the stirring assembly 16 includes a fixing shaft 161 transversely disposed in the collection tank 13 and fixedly connected to an inner wall of the collection tank 13, the fixing shaft 161 is provided with a rotating disc 162, the rotating disc 162 is connected to a power member for driving the rotation of the rotating disc 162, two horizontal main stirring rods 163 are respectively installed on two sides of the driving wheel 162, the left and right main stirring rods 163 are distributed in a central symmetry manner with respect to a center of the rotating wheel 162, and a plurality of auxiliary stirring rods 164 are distributed on an outer circumferential surface of each main stirring rod 163 along an axial direction thereof.
When the rotary disc 162 rotates, the two main mixing rods 163 rotate together, and a rotation manner similar to that of a bicycle pedal is formed, and the concrete in the collection tank 13 is secondarily mixed in cooperation with the mixing of the auxiliary mixing rods 164.
Further, the transfer processing device 30 comprises a transfer tank 31 which is arranged below the collection tank 13 and integrally connected with the bottom of the collection tank 13, the transfer tank 31 is fixed above the integrated casting machine 20 through an installation frame 32, an interlayer cavity 311 for introducing cooling water is arranged on the outer wall of the transfer tank 31, an inlet 313 communicated with the transfer tank 31 is formed in the bottom of the collection tank 13, a blocking piece 33 for intermittently closing the inlet 313 is arranged in the transfer tank 31, a flaring 312 for sending the concrete received by the transfer tank 31 into the integrated casting machine 20 at one time is formed in the bottom of the transfer tank 31, and an electromagnetic valve is arranged at the flaring 312.
The purpose of the transfer device 30 is to receive the concrete in the collection tank to a certain amount and then put it into the all-in-one casting machine, since the collection tank 13 in the previous step stirs the concrete for the second time, under the condition of high temperature, the temperature of the concrete after being stirred is probably higher, and the reduction of the temperature of the concrete is beneficial to the high-quality completion of the concrete pouring, so the outer wall of the transit tank 31 is provided with a warehouse adding cavity, meanwhile, the intermittent closed design of the inlet 313 can prevent the quick loss of the cold energy of the interlayer cavity 311 and the poor cooling effect caused by the long-time opening of the concrete in the transit tank 31, on the other hand, the inlet 313 is opened once after the stirring component 16 in the collecting tank 13 rotates each time, the large load of the stirring component 16 caused by too much concrete in the collecting tank 13 can be avoided, and the concrete after bottom layer stirring is released after each stirring, so that the collecting tank 13 is in high-efficiency operation.
Specifically, the blocking piece 33 comprises an adapter rod 331 arranged in the collection tank 13 and a plug 332 arranged in the transit tank 31, one end of the adapter rod 331 is rotatably connected with one of the main stirring rods 163, the other end of the adapter rod 331 is rotatably connected with a linkage rod 333, and the linkage rod 333 extends into the transit tank 31 along the inlet and is connected with the plug 332.
