Description

[Detailed description of the invention] This invention relates to a concrete block molding machine that can continuously perform molding based on a cast mold.

Generally speaking, there are two ways to mold concrete blocks; one is a primitive mold, but the other is an automatic molding machine equipped with a vibrator that compresses the concrete. Although it has advantages that cannot be expected from the latter, its biggest drawback is that it is extremely inefficient to mold continuously in large quantities.

Therefore, this idea was developed by placing the upper edge of the mold body on a rail and locking the lower end with an endless conveyor chain, and creating a pallet on the upper edge of the mold body that extends inside and out of the mold body and has a protrusion downward. A locking pawl is provided, and a retracting guide is provided on the rail so that the lower protrusion of the pallet locking pawl engages with the pallet locking pawl so that the pallet locking pawl appears and retracts from the inside and outside of the mold body, and A vibrator is installed at a desired location during the transfer of the mold body, and the molding process is performed continuously by filling the moving mold body with concrete, applying vibration, and then securing it with a pallet. The object of the present invention is to provide a concrete block molding machine that enables efficient molding.

Now, one embodiment of the concrete block molding machine according to this invention will be described based on the drawings. 1 is a mold body whose upper edge 2 is placed on a rail 3 and whose lower end is locked to an endless conveyor chain 4. , 5 are pallet locking claws arranged on the upper edge 2 of the mold body 1.

The pallet locking pawl 5 is freely movable through the upper edge 2 of the mold body 1, penetrating the inside and outside of the mold body 1, and is located at the end of the pallet locking pawl 5 that protrudes to the outside. A protrusion 6 is provided to protrude downward from the portion.

The protrusion 6 engages with guide members 7 and 8, which will be described later.

7 is a guide member for moving the pallet locking claw 5 toward the outside of the mold body 1; 8 is a guide member for moving the pallet locking claw 5 toward the inside of the mold body 1. be.

These guide members 1 and 8 are both fixed on the rail 3, and the guide member 7 is located at the front and the guide member 8 is located at the rear in the direction in which the mold body 1 moves.

Reference numeral 9 denotes a vibrator disposed in a part of the path for conveying the mold body 1, and this vibrator 9 is disposed at a position so as to be in contact with the lower part of the mold body 1.

In addition, 10 in the figure is a concrete supply hopper, and 11 is a concrete supply hopper.
is the pressure roller placed immediately after that.

Then, the conveyor chain 3 is rotated and the vibrator 9 is activated to sequentially transfer the mold bodies 1.

This mold body 1 is a concrete supply hopper 10.
When the concrete reaches just below the mold body 1, the mold body 1 is filled with concrete, and the pressing roller 11 presses the upper surface of the concrete filled in the mold body 1 to equalize it.

In this position, the pallet locking claw 5 on the upper edge 2 of the mold body 1
The lower protrusion 6 is moved outward by the guide member 7, and the pressure roller 11
After passing through, the mold body 1 reaches the top of the vibrator 9, and by applying vibration, concrete clogs every corner of the mold body 1.

The mold body 1 moves further, but when the pallet (P) is placed on the mold body 1 after passing through the vibrator 9, the pallet locking claw 5 is eventually moved toward the inside of the mold body 1 by the guide member 8. , so that the pallet (P) and the mold body 1 are connected by the pallet locking pawl 5.

Operations such as concrete filling, vibration, and pallet capping are performed continuously by continuously transporting the mold body 1, and after these operations are completed, the mold is removed from the rail 3. The block is manufactured by removing the main body 1 and curing it.

As mentioned above, although the concrete block molding machine of this invention is based on a pouring mold in principle, it is possible to continuously mold the mold, and it is extremely effective in improving its efficiency. This has the effect of
