摘要

The compressed air operated sand spreading device has a sand suction chamber (36) connected to the sand container (14), and a nozzle (20) connected to a compressed air source, whereby the nozzle has an air inlet, ejection channel (26) and a sand suction opening (28). The sand suction chamber is connected to the nozzle directly or indirectly through the sand suction opening. The nozzle and suction chamber are located in a sand outlet (16) provided on the sand container. Independent claims are included for a sand outlet and for a nozzle for a sand spreading device.
