[0012] The utility model is further configured as follows: one side of the rear partition is provided with an inclined discharge chute for facilitating the discharge of leaked concrete.

[0013] In summary, the beneficial effects of the utility model are:

[0014] 1. When delivering concrete to the forming mold, the lifting mechanism is first used to drive the limit vibration mechanism to move upward so that the top of the forming mold is embedded in the material distribution channel; the second cylinder then drives the material distribution hopper to move so that the material distribution hopper is located on the front partition, and the concrete in the material distribution hopper falls into the forming mold; the second cylinder then drives the material distribution hopper back to the rear partition to reset; the lifting mechanism drives the limit vibration mechanism to move downward for a distance, and then the limit vibration mechanism is vibrated to make the gaps and bubbles in the concrete evenly distributed; finally, when the lifting mechanism drives the limit vibration mechanism to reset, the connecting bottom frame falls on multiple discharge rollers again, and the first cylinder and the push plate push the connecting bottom frame and multiple forming molds out; in this process, the processing efficiency is improved;

[0015] 2. During the movement of the distribution hopper, some concrete will seep out along the gaps between the distribution hopper and the front partition, and between the distribution hopper and the rear partition. Since the two sides of the front partition correspond to the rotation points of the two ends of the discharge roller, a retaining frame is set at this time to prevent the infiltrated concrete from leaking from the edge of the front partition, thereby avoiding affecting the rotation of the discharge roller;

[0016] 3. The limit clamps on the limit vibration mechanism can limit the corners of the bottom frame, and drive the vibration plate to vibrate when the vibration motor moves, thereby achieving the compaction of the concrete in the molding mold;

[0017] 4. The lifting mechanism includes a positioning sleeve, a lifting shaft and a third cylinder, so that when the third cylinder is working, the bottom plate of the limit vibration mechanism can be driven to lift;

[0018] 5. The heights of the first side plate and the second side plate are the same, and the length of the second side plate is 1.5-2 times of the length of the first side plate. From now on, when the concrete is transported to the distribution hopper, the concrete input point can be the second side plate. After the concrete is input, it flows under the action of its own gravity and fills the distribution hopper, thereby reducing the gaps and bubbles in the concrete; at the same time, the setting of the reinforcing ribs plays a role in structural reinforcement.

The plurality of cloth feeding channels 531 correspond to a plurality of forming molds on the connecting bottom frame. A lifting mechanism 7 for driving the limit vibration mechanism 6 to move upward so that the tops of a plurality of forming molds on the connecting bottom frame are embedded in the cloth feeding channels 531 is arranged between the bottom of the limit vibration mechanism 6 and the frame 1.

[0026] As Figure 1 and Figure 2 shown, a retaining frame 55 protruding upward and in a "U" shape is arranged on the part of the upper surface edge of the front partition plate 53 that is not in contact with the rear partition plate 54, and both ends of the retaining frame 55 extend to both sides of the rear partition plate 54. An inclined discharge chute 8 for guiding the discharged concrete to leak is arranged on one side of the rear partition plate 54.

[0027] As Figure 1and Figure 3 As shown, the upper end of the material distribution hopper 51 is a flared end 511 with a flared setting, and the flared end 511 includes a first side plate 512 close to the side connected to the output direction of the bottom frame, a second side plate 513 away from the side connected to the output direction of the bottom frame, and two third side plates 514 arranged between the first side plate 512 and the second side plate 513. The first side plate 512 and the second side plate 513 have the same height, and the length of the second side plate 513 is 1.5-2 times the length of the first side plate 512. A plurality of reinforcing ribs 515 are arranged between the lower surface of the second side plate 513 and the side wall of the material distribution hopper 51.

[0028] like Figure 1 and Figure 2 As shown, the limiting vibration mechanism 6 includes a base plate 61, a plurality of damping shock absorbers 62 arranged on the base plate 61, a vibration disk 63 arranged above the plurality of damping shock absorbers 62, a vibration motor 64 arranged on the lower surface of the vibration disk 63, a plurality of lifting plates 65 arranged on the vibration disk 63 and capable of passing through a plurality of discharge rollers 2 during upward movement, limiting clips 66 respectively arranged at both ends of two lifting plates 65 located on both sides and limiting the corners of the bottom frame, and a lifting mechanism 7 is arranged between the base plate 61 and the frame 1.

[0030] Implementation effect: When delivering concrete to the forming mold, firstly, the lifting mechanism 7 drives the limit vibration mechanism 6 to move upward so that the top of the forming mold is embedded in the distribution channel 531; then, the second cylinder 52 drives the distribution hopper 51 to move so that the distribution hopper 51 is located on the front partition 53, and the concrete in the distribution hopper 51 falls into the forming mold; then, the second cylinder 52 drives the distribution hopper 51 back to the rear partition 54 for reset; then, after the lifting mechanism 7 drives the limit vibration mechanism 6 to move downward for a distance, the limit vibration mechanism 6 is vibrated to make the gaps and bubbles in the concrete uniformly distributed; finally, when the lifting mechanism 7 drives the limit vibration mechanism 6 to reset, the connecting bottom frame falls on the multiple discharge rollers 2 again, and the connecting bottom frame and the multiple forming molds are pushed out by the first cylinder 3 and the push plate 4; in this process, the processing efficiency is improved.

[0031] During the movement of the distribution hopper 51, some concrete will seep out along the gaps between the distribution hopper 51 and the front partition 53, and between the distribution hopper 51 and the rear partition 54. Since the two sides of the front partition 53 correspond to the rotation points at both ends of the discharge roller 2, a retaining frame 55 is provided at this time to prevent the infiltrated concrete from leaking from the edge of the front partition 53, thereby preventing the rotation of the discharge roller 2 from being affected. The limit clamp 66 on the limit vibration mechanism 6 can limit the corner of the connection bottom frame, and drive the vibration plate 63 to vibrate when the vibration motor 64 moves, thereby realizing the vibration compaction of the concrete in the forming mold. The lifting mechanism 7 includes a positioning sleeve 71, a lifting shaft 72 and a third cylinder 73, so that when the third cylinder 73 is working, the bottom plate 61 of the limit vibration mechanism 6 can be driven to lift and lower. The first side plate 512 and the second side plate 513 have the same height, and the length of the second side plate 513 is 1.5-2 times the length of the first side plate 512. From now on, when the concrete is transported into the distribution hopper 51, the concrete input point can be the second side plate 513. After the concrete is input, it flows under the action of its own gravity and fills the distribution hopper 51, thereby reducing the gaps and bubbles in the concrete; at the same time, the provision of the reinforcing ribs 515 plays a role in structural reinforcement.
