Chocalho is the generic name for "shaker" in Portuguese.
There are various types of idiophones using this name in Portuguese, not always being the same instrument: Chocalhos are typically used as a support to the sound of the caixas, to sustain the rhythm in the bateria.
This instrument consists of an aluminum or wooden frame with a number of rows, each carrying pairs of jingles (platinelas[what language is this?]).
The chocalho is played by shaking it back and forth and pumping the arms up and down.
