Filling-truck for machine making concrete blocks

摘要

The truck travels from below the storage silo over the mould for the block. It has a bottom grid (13) with transverse bars (14,15). The inner portion (13a) of the grid towards the mould has an automatic locking mechanism (16) shutting it in the filling position below the silo, and opening it in the emptying position above the mould. In the movement direction the locking mechanism can have sliding strip-type transverse bars (17) covering the gaps (18) between the fixed bars (15) of the inner section in the shut position. They are moved above the fixed bars in the open position to free the gaps.
