Description

Steel fiber feeder for concrete strength reinforcement

The present invention relates to a feeder for adding a steel fiber to increase the strength of the cured concrete by adding to the ready-mixed concrete made of sand, gravel, cement, water.

Concrete used in concrete buildings or bridges, roads, etc., is a mix of cement, gravel, sand, and water. The concrete is transported by ready-mixed concrete vehicles. Concrete will be poured into the formwork.

By curing the cast concrete as described above for a certain period of time to build a concrete structure.

As mentioned above, steel fiber is added to concrete as one of means for increasing the strength of concrete (remixture) in a country where construction and civil engineering technology is advanced to reinforce strength of concrete using concrete.

When steel fiber is added to concrete as described above, it has higher strength than concrete without adding steel fiber. For example, when the steel fiber is added to about 15 ㎏ by adding about 30 kg of steel fiber to concrete, The same strength as when poured at 25 cm can be obtained.

As described above, the steel fiber added to the concrete is made by a steel fiber injector. A process of injecting steel fiber into a ready-mixed concrete using a conventional steel fiber injector is as follows.

Workers pour the steel fibers packed in the bag into the feed hopper of the feeder.

As described above, the steel fiber poured into the supply hopper falls to the ejector connected to the lower portion of the supply hopper through the mesh of the supply hopper.

As described above, the steel fiber dropped by the ejector is transported along the steel fiber transport pipe by the air of the air that blows the air into the ejector, and is introduced into the hopper of the ready mixed concrete to be mixed into the ready mixed concrete.

The feeder for injecting the steel fiber into the ready-mixed concrete as described above is to drop the steel fiber injected into the supply hopper to the ejector through the mesh panel in a flat state, firstly, there is a hassle that the worker must spread the steel fiber poured on the hopper evenly; Secondly, there is a disadvantage in that unnecessary labor loss occurs because the worker for unfolding the steel fibers must reside in the feeder; Thirdly, the steel fibers are not supplied to the concrete (mixed concrete) in a uniform amount, so that the mixing of the steel fibers is not uniform, and there is a disadvantage that the strength imbalance of the concrete structure occurs; Fourth, the method for lowering the height of the conveying tube for transporting steel fibers was a slide method had a disadvantage that takes a lot of force to lower the conveying tube is a heavy object.

In order to solve the above problems of the conventional steel fiber feeder, the present invention, the steel fiber is poured into the chute-shaped chute that is rotated up and down around the hinge by the lifting and lowering operation of the cylinder to the power of the drum drive motor. By supplying to the rotating drum by rotating force of the rotating drum, the proper amount of steel fiber exits the steel fiber discharge hole and transfers the steel fiber dropped to the ejector through the hopper along the transfer pipe to the air generated in the fan, By mixing steel fibers in ready-mixed concrete, first, the steel fiber poured chute is gradually raised by the operation of the cylinder so that the steel fiber poured into the chute is supplied in proper amount in the rotating drum so that the steel fiber is well spread in the rotating drum. At the same time, it can be discharged into the steel fiber discharge hole by the proper amount by centrifugal force. Are steel fibers are uniformly mixed with respect to the total ready-mixed concrete vehicles of the cone; Secondly, a concrete structure having uniform strength can be obtained by even mixing of steel fibers; Third, to solve the hassle of unfolding the steel fiber as in the prior art, it is possible to prevent the loss of labor because no separate labor is required to unfold the steel fiber; Fourth, to improve the steel fiber feed pipe from the sliding type to the hinge folding type to provide a steel fiber feeder for concrete strength reinforcement can easily reduce the height of the steel fiber feed pipe.

The present invention for achieving the above object, has a moving wheel to move, the corner is provided with a cylinder for fixing the position to prevent the flow of the device during operation, the vehicle body having a support hopper is fixed to the center A frame; The drum has a bottom plate of ordinary light and narrow side shape, and an hopper having an opening having a steel fiber guide plate on one side, and a hopper fixed to the support of the body frame by being covered with an upper portion, and a drum installed inside the hopper opposite to the opening of the hopper. Rotation drum is rotated by the drive motor is installed, the rotation drum, the O-ring-shaped flesh is arranged at regular intervals so that the steel fiber discharge hole is formed and the steel fiber input portion formed in a cylindrical shape; A bracket formed under the tip is hinged to the fixing bracket of the support so that the tip is located in the opening of the hopper, and a bracket formed at a point spaced from the bracket is connected to the rod of the cylinder hinged to the body frame. It is to be rotated up and down around the hinge by the operation of the cylinder, and the chute having both side walls and the rear end wall to accommodate the steel fibers; An ejector which is connected to the bottom plate of the hopper by a connection pipe and is discharged from the rotating drum so that the steel fiber is dropped through the hopper and transfers the steel fiber to the supply of air generated by the rotation operation of the fan; One end is flange-coupled to the ejector so that the steel fibers dropped by the ejector can be mixed into the ready-mixed concrete of the ready-mixed vehicle, and the other end is bent to be stably positioned in the hopper of the ready-mixed vehicle. Achievement is achieved by consisting of a steel fiber conveying tube hinged to be folded and retracted.
