Abstract
A salt and/or gravel spreader comprising a mobile container or hopper constructed to have two bottom walls, transverse to the direction of travel, inclined downwards towards an oblong slot at which is mounted a mechanism for the discharge of salt and/or gravel. The lower part of one of the inclined bottom walls has at least one pivotally mounted slat protruding beneath the other inclined bottom wall. Below one or all the pivotal slats is situated a rotatable shaft having a cam for each slat, whereby the slat(s) at the free end through the rotation by the shaft of the cam(s) will swing towards or away from the edge of the other inclined bottom wall. The spreader cannot be blocked by the spreading material and easy adjustment of the dosing can be performed during operation.
