2. Description of the Related Art Most conventional concrete injection devices are of a simple machine operation type for the purpose of merely injecting concrete into the molding mold, or the concept of automatic control has not been applied concretely or positively. It was a thing. That is, Japanese Patent Publication No. 53-29690 discloses a concrete supply mechanism in which a concrete unloader using a screw conveyor is attached to the lower part of a throwing machine equipped with a hopper and a fixed amount is supplied through a constant amount supply mechanism. ing. The supply mechanism shown in this publication is only for concrete supply, and the quantitative supply mechanism is not described at all. Japanese Patent Publication Sho 57
No. 42011 and Japanese Patent Publication No. 58-49731 disclose a concrete charging mechanism composed of a hopper, a belt conveyor and a concrete discharging mechanism. Since the operating mechanism for feeding conveyor belt speed and water supply is not configured as an interlocking system, it is impossible to set proper feeding conditions by changing the standard of concrete pipes. In addition, the control system of the supply mechanism also electrically detects only the compacted state of concrete at the position where the cocrete was thrown in, through the compaction roller,
Only the method of sequentially moving the conveyor is disclosed, and the technical configuration for feeding a certain amount of concrete is not disclosed at all.

Furthermore, Japanese Patent Publication No. 57-3264
The concrete supply device disclosed in Japanese Patent No. 4 is configured with two advancing / retreating quantitative containers each having a filling section and a closing section below the hopper, and concrete is filled from the hopper into the filling section of the quantitative container. Since it is a method that alternately discharges concrete onto the conveyor belt when the metering container moves forward, there is a lack of means for accurately grasping the amount of concrete discharged onto the conveyor from the hopper through the filling section. There is. Note that the concrete supply device is merely a means for supplying concrete, and no consideration is given to operating factors such as conveyor speed and hopper input adjustment. As can be seen from the above prior art, the conventional concrete pouring device is only for the purpose of pouring concrete in the entire pouring process without relying on a consistent automatic control drive method.
In addition, even if centrifugal force is used, uniform distribution of concrete cannot be expected, and even if a certain amount of concrete that meets the specifications of concrete pipes is added at one time, even concrete distribution, especially in the socket part Could not be achieved. Even if an attempt is made to evenly disperse the concrete by centrifugal force, the slump of the concrete becomes high, the strength is weakened by the aggregate separation phenomenon during centrifugal rotation, and a large amount of sludge is generated and scattered by the dehydration phenomenon. Therefore, the quality and appearance of the product are not uniform, and waste water is generated to cause environmental pollution.

The slump of can be maintained. Therefore, by constructing the concrete quantitative uniform pouring device, its driving system and its driving method of the present invention as described above, a predetermined amount of water is jetted while moving forward and backward under a controlled condition in a subdivided certain section. At the same time, concrete can be put in a fixed amount, there is no waste of concrete, and there is no generation of slatch and waste water due to dehydration and scattering of concrete during centrifugal rotation of the molding mold, thus preventing environmental pollution. Therefore, it is possible to manufacture a high-strength concrete pipe having an excellent appearance with no separation phenomenon of aggregate, and it can be expected to make a great industrial contribution in this field.
