Granular material e.g. gravel, spreading device for e.g. farm and/or road and/or highway vehicle, has unit channeling flow of material on roller such that density of material on its spreading width is uniform

摘要

#CMT# #/CMT# The device has a channeling unit (57) that channels a flow of a granular material (51) on a rotating distributing roller (54) in an outlet passage of one trap door (58) of a set of trap doors (55) such that the width of the spreading of the material on the ground (500) corresponds to a multiple of the width of the passage of the trap door through which the material flows. The density of the material on its spreading width is uniform. The unit (57) comprises a set of partition walls enclosing the distributing roller. #CMT# : #/CMT# An independent claim is also included for a farm and/or road and/or highway vehicle comprising a coater and spreader. #CMT#USE : #/CMT# Used in agricultural and public work fields for spreading a granular material such as gravel, that is contained in an open carrier of a vehicle e.g. farm and/or road and/or highway vehicle comprising a coater and spreader (claimed) and utilized for laying and repairing of the road and/or highway and/or public transport way and/or public or private structure. #CMT#ADVANTAGE : #/CMT# The channeling unit channels the flow of the granular material on the roller such that the density of the material on its spreading width is uniform, thus optimizing the quantity of the spreading of the granular material e.g. gravel, with a uniform density along the entire width of the ground which is to be covered with the gravel, and hence improving the safety of users on the road and/or highway working space. The device thereby avoids scattered deposit of the gravels in the edges of the ground to be covered and hence the wastage of the granular material is thereby avoided. The arrangement of the partition walls allows to control the material spreading width in a precise manner. The device can be adapted to any type of spreader in a better manner and can be manufactured in an inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an operation of a spreader. 51 : Granular material 54 : Rotating distributing roller 55, 58 : Trap doors 57 : Channeling unit 500 : Ground.
