The mounting bracket 24 is bolted to the right end of the front side of the frame 1. Two first sprockets 25 are mounted at both ends of the first rotating shaft 23 via keys. One end of the chain 26 is meshed with the first sprockets 25.

[0021] The tensioning assembly 4 includes a connecting shaft 41, two second sprockets 42 are rotatably mounted at both ends of the connecting shaft 41 via bearings, the two second sprockets 42 are meshed with the chain 26, and two tension sensors 43 are distributed front to back and mounted at both ends of the bottom surface of the connecting shaft 41 via bolts. The bottom end of the tension sensor 43 is mounted at the telescopic end of the first electric telescopic rod 3 via bolts.

[0022] The transition assembly 6 includes two second electric telescopic rods 61, which are bolted to both ends of the surface of the connecting frame 5. The U-shaped frame 62 is bolted to the telescopic ends of the two second electric telescopic rods 61, and two electric rollers 63 are rotatably mounted on the inner side wall of the U-shaped frame 62 via bearings.

[0023] The second shaft 7 is rotatably mounted on the left end of the inner side wall of the frame 1 via bearings at both ends. Two third sprockets 8 are mounted on both ends of the second shaft 7 via keys. The third sprockets 8 are meshed with the end of the chain 26 away from the first sprocket 25.

[0024] The support frame 9 is bolted to the corner of the bottom surface of the frame 1. The control panel 10 is bolted to the middle of the front side of the frame 1.

The electric roller 62 forms a transition between the two chain machines, reducing the gap between the chains 26 of the two chain machines and preventing the concrete blocks from falling due to the gap during conveying. This utility model has the advantages of being easy to use and having good performance.
