Road vehicle for spreading aggregate on road comprises storage hopper with opening slot and movable extractors directing flow towards road, force sensor measuring impact force

摘要

The vehicle for spreading aggregate (G) on a road comprises an aggregate storage hopper (10) having a slot opening (110) located horizontally and transversely relative to the vehicle displacement direction. Movable extractors (2) are connected to the hopper. The aggregate flow (F) which flows through the slot is taken by the extractors before being directed towards the road (R). A force sensor (3) located in the aggregate flow path measures the impact force of the aggregate. A deflector (4,5) is located between the sensor and the road.
