Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0065] The technical solutions of the present application will be described below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application. Figures 1 to 13 The concrete distributing device 100, the distributing machine 1000 and the prefabricated part production line involved in the present application are described.

[0066] Figure 9 and Figure 10 A concrete placing machine 1000 is shown, which comprises a carrying support 7 and a concrete placing device 100. The concrete placing device 100 is mounted on the carrying support 7, and a placing space is formed below the concrete placing device 100. Specifically, as shown in Figure 9 and Figure 10 The carrying support 7 is in a door-shaped structure as a whole, and the upper portion of the carrying support 7 is provided with two placing device mounting beams 71. The concrete placing device 100 is connected to the two placing device mounting beams 71 through the hoppers 1. The lower portion of the carrying support 7 is provided with two carrying cross beams 73, which are connected to the placing device mounting beams 71 through support columns 72 to support the placing device mounting beams 71. The carrying cross beams 73 are provided with a traveling mechanism. The traveling mechanism comprises wheel assemblies 74 mounted on the carrying cross beams 73 for traveling of the placing machine 1000, and a traveling drive assembly 75 in driving connection with the wheel assemblies 74. In specific implementation, a track adapted to the wheel assemblies 74 is laid on the foundation, so that the placing machine 1000 can travel along the track according to production needs.

[0067] As some alternative embodiments of the present application, the carrying support 7 can not comprise the carrying cross beams 73, and the placing machine 1000 can be directly fixed to the foundation through the support columns 72 (not shown in the figure).

[0068] Figure 11 and Figure 12 Another concrete placing machine 1000 is shown, which comprises a traveling frame 9 and a concrete placing device 100. The concrete placing device 100 is mounted on the traveling frame 9. Specifically, as shown in Figure 13 The traveling frame 9 comprises first and second traveling beams 91 and 92 arranged side by side, and the concrete placing device 100 is arranged on the first and second traveling beams 91 and 92 through the hoppers 1. The first and second traveling beams 91 and 92 are provided with wheel assemblies for traveling, and at least part of the wheel assemblies are in driving connection with drive motors. In specific implementation, a track for traveling of the placing machine 1000 can be selectively laid at a suspended position, so that the placing machine 1000 is arranged on the track, and the position of the placing machine 1000 can be adjusted as needed.

[0069] As shown in Figures 1 to 4As shown, the concrete distributing device 100 provided by the present application comprises a hopper 1, a transfer assembly 2 and a guide channel 3. The lower part of the hopper 1 is provided with a hopper discharge port. The transfer assembly 2 is located below the hopper discharge port, and the transfer assembly 2 is provided with a bin 21 for accommodating concrete, the bin 21 comprises a bin inlet 211 and a bin outlet 212, and the bin inlet 211 is located directly above the bin outlet 212, and the hopper discharge port extends to the upper surface of the transfer assembly 2. In specific implementation, the hopper discharge port and the transfer assembly 2 are further gap-fitted, and the gap between the lower edge of the hopper discharge port and the transfer assembly 2 is between 0-5mm. When the transfer assembly 2 transfers concrete, the hopper sidewall at the hopper discharge port can stop the concrete. In specific implementation, a stopper scraper can be selectively arranged on the hopper, and the stopper scraper can scrape off the concrete on the upper surface of the transfer assembly 2 during the distribution process, so as to better ensure that the amount of concrete transferred by the transfer assembly 2 is more accurate, and the amount of concrete leaked during the distribution process can also be effectively reduced.

[0070] In addition, the transfer assembly 2 has a first position and a second position. The guide channel 3 is located below the movement track of the transfer assembly 2, and the guide channel 3 comprises a guide inlet 31 and a guide outlet 32, and the guide inlet 31 is located above the guide outlet 32. As shown in Figures 1 to 8 and Figure 8.1 As shown, the concrete distributing device 100 is provided with three guide channels 3, and the guide inlet 31 of each guide channel 3 is located above the guide outlet 32.

[0071] As preferred, as shown in Figures 1 to 4 The guide channel 3 is located on one side of the hopper 1, so as to facilitate the cleaning operation of the concrete distributing device after the distribution is completed.

[0072] In specific work, the concrete distributing device 100 is configured such that when the transfer assembly 2 is in the first position, the hopper discharge port is in communication with the bin inlet 211, and the bin outlet 212 is closed; when the transfer assembly 2 is in the second position, the hopper discharge port is closed, and the bin outlet 212 is in communication with the guide inlet 31. The continuous distribution of the concrete distributing device 100 is realized during the switching process of the transfer assembly 2 between the first position and the second position.

[0073] It should be noted that the structure of the hopper 1 in the present application is not specifically limited, and it can be any hopper that meets the distribution requirements. Specifically, the hopper 1 can be a whole funnel type. In order to make the concrete fall more uniformly and smoothly, a stirring device 11 (as shown in Figure 4 ) can be further arranged on the hopper 1.

[0074] It should also be noted that the structure of the material guiding passage 3 in the present application is not specifically limited, and it can be any tubular passage capable of guiding material during the material distribution process. In specific implementation, the material guiding passage 3 can be a square passage, a circular passage, a gradually changing passage, etc. Specifically, as shown in Figure 2 and Figure 3 the material guiding passage 3 is a gradually changing passage along the material guiding direction, and the cross section of the material guiding passage 3 perpendicular to the material guiding direction is square. In addition, in specific implementation, the material guiding passage 3 can be a straight passage or a curved passage, and in specific implementation, the material guiding passage 3 is preferably a straight passage.

[0075] In specific implementation, the transfer assembly 2 is pushed and pulled by the push-pull assembly, so that the material bin 21 on the transfer assembly 2 can be relatively displaced relative to the hopper 1 and the material guiding passage 3, and thus the transfer assembly 2 can be switched between the first position and the second position, so that the transfer assembly 2 has the conditions for taking material and distributing material.

[0076] The present application realizes the transfer and distribution of concrete by making the concrete distribution device 100 include the transfer assembly 2 having the material bin 21 containing concrete, and making the transfer assembly 2 capable of position adjustment between the defined first position and second position, so that the material bin discharge port 212 can be in a closed state or in a state of communication with the material guiding inlet port 31 as needed, thereby realizing the accurate distribution of the concrete distribution device 100, since the capacity of the material bin 21 remains constant during the transfer of concrete.

[0077] Specifically, when the transfer assembly 2 is in the first position, the hopper discharge port is in communication with the material bin inlet port 211, and the material bin discharge port 212 is in a closed state, and the concrete in the hopper 1 enters the material bin 21. When the transfer assembly 2 is in the second position, the hopper discharge port is in a closed state, and the material bin discharge port 212 is in communication with the material guiding inlet port 31, so that the concrete in the material bin 21 is distributed through the material guiding passage 3. Figures 1 to 4 The concrete distribution device shown is in the first position, and the hopper discharge port is located directly above the material bin inlet port 211. As shown in Figure 8 and Figure 8.1 the material bin discharge port 212 is stopped by the stopper and is in a closed state.

[0078] As some preferred embodiments of the present application, the concrete distribution device 100 further includes a bearing base 4 and a first stopper 51. As shown in Figures 1 to 4 the bearing base 4 is fixed below the hopper 1. The transfer assembly 2 is located between the bearing base 4 and the hopper 1. In specific operation, the transfer assembly 2 can be moved relative to the bearing base 4 in the X direction, so that the transfer assembly 2 has a first position and a second position, and the transfer assembly 2 is switched between the first position and the second position.

[0079] As shown in Figure 3 , Figure 4 and Figure 8.1 , the first stopper 51 is installed on the upper surface of the bearing base 4, and the first stopper 51 comprises an upward first stop surface. The material guide channel 3 is installed on the bearing base 4, and the first stop surface extends to the material guide inlet 31 along the X direction. The extension length of the first stop surface along the X direction is greater than the transfer stroke of the transfer assembly 2, so that the transfer assembly 2 can block the bunker outlet 212 as required during the transfer of the concrete. In the specific working process, when the transfer assembly 2 is in the first position, the first stop surface blocks the bunker outlet 212; when the transfer assembly 2 is in the second position, the bunker 21 is in communication with the material guide channel 3, and the bunker outlet 212 is located directly above the material guide inlet 31.

[0080] It should be pointed out that the bearing base 4 in the present application is not specifically limited, which can be any structure meeting the requirement of bearing the transfer assembly 2. In the specific implementation, the bearing base 4 can be selectively made into a frame structure by profile processing, and the bearing base 4 is fixed below the hopper 1. As shown in Figures 1 to 8 and Figure 8.1 , the bearing base 4 is a frame structure spliced by channel steel, and a channel steel beam extending along the Y direction is further arranged on the bearing base 4. It should be noted that the bearing base 4 in the present application can be fixed below the hopper 1 through a support structure, or the bearing base 4 can be fixedly connected with the hopper 1 below the hopper 1; but preferably, the bearing base is fixedly connected with the hopper 1.

[0081] It should be further pointed out that the first stopper 51 in the present application is also not specifically limited, which can be any structure having a first stop surface, so that the transfer assembly 2 can block the bunker outlet 212 when the transfer assembly 2 is in the first position. As shown in Figure 8 , when the transfer assembly 2 is in the first position, the first stop surface is in the position of blocking the bunker outlet 212, and the first stop surface extends to the material guide channel 3, so that the transfer assembly 2 can reliably block the bunker outlet 212 during the process of transferring the concrete to the material guide channel 3. In the specific implementation, preferably, the first stopper 51 is a flat plate structure.

[0082] The present application sets the first stopper 51, and makes the first stop surface comprised by the first stopper 51 extend to the material guide inlet 31 along the X direction, so that the bunker outlet 212 can be blocked when the transfer assembly 2 is in the first position, to prevent the concrete from leaking during the transfer process, and to ensure the normal distribution of the concrete distribution device. In addition, such arrangement not only meets the transfer condition of the concrete, but also has the advantages of simple structure and the like.

[0083] As some preferred embodiments of the present application, Figures 1 to 7 As shown, the concrete placing device 100 further includes two running rails 41 mounted on the supporting base 4. The two running rails 41 are respectively mounted on either side of the first stopper 51 and extend in the X-direction.
