In the sand canister a drive mechanism is built in which is consisted of the following parts(picture 1): One way current electromotor (2),drive power 12V in th ring backup (3) and fixed withe the cutted ring (4).Electromotor has to power the extended shaft (5), (picture 3).The extende shaft is screwed on the axis of the electromotor ,and on it a lose sliding attachement the twisting shaf t(7) (picture 5).Between the rings of tli twisting and extended shaft a reversable spring is attached (6) (picture 4), which loweres and heightenes the twistin axis so it can,over the disk( 12), (picture 10)openes and sloses the sand opening. On the lower,thiner part of the twisting shaft a sliding nail (l 1) (picture 9), bordered by th pad (10), which pushes the sand onto the disk (12) (picture 1O). It is tightened by the screw (13). The disk equally disperses th sand in front of the wheels. A protecting cover (14) (picture 11), stops the entering of sand and dirt in the moving parts of the mechanism. |
