In addition, the timing belt 34 is wound around the timing pulley 32a coupled to the drive motor 32 and the timing pulley 36a coupled to the reducer 36 to accurately transmit rotational force, and within the reducer 36. The reduced rotational force at is configured to be transmitted to the drive wheel 38 through the deceleration pinion 36b.

Meanwhile, as illustrated in FIG. 6, the clamp means 40 includes a key plate 42 mounted below the support pillar 20, a hinge shaft 44 protruding from the key plate 42 toward the front side, and And a pair of fixing members 46a and 46b rotatably coupled to the hinge shaft 44, and coupled to an upper side of the fixing members 46a and 46b to operate according to the fixing members 46a and 46b. The lower end is made of a cylinder 48 to fix or release the rail (R), the cylinder 48 is provided with a rod (48a).

The guide rail 22 is fixedly installed in the longitudinal direction on the upper side of the support pillar 20, and the fixing frame 24 is fixed in the lateral direction on the inside thereof.

In the guide rail 22, a rack 22a is formed at the lower side in the longitudinal direction, and a rail portion 22b is formed at the upper side.

The guide rail 22 is coupled to the concrete inserting means 50 for introducing concrete into the mold M so as to be movable in the longitudinal direction.

The concrete inserting means 50 is a bucket portion 52 in which the concrete is stored therein, and fixed to both sides of the bucket portion 52, both ends of the rotary wheel (rolling) rolling on the rail (22b) ( A moving frame 54 rotatably coupled to 54a and a vibration generating unit 56 for applying a vibration to the bucket unit 52 to uniformly discharge the concrete.

The lower side of the moving frame 54 is coupled to the guide roller 54b in contact with the lower side of the rail portion 22b and rolling.

The concrete input means 50 is coupled to the lower end of the height adjusting plate 58 for maintaining a constant upper surface of the concrete injected into the mold (M), the height adjustment plate 58 is in contact with the concrete surface As a result, a scratching portion 58a is formed to even the upper surface.
