Feeder for e.g. sand, has driving mechanism comprising driven shaft coupled with rope hoist drivable with variable rotation speed, where rotation speed is adjustable by hand through remote control device

摘要

#CMT# #/CMT# The feeder (18) has a traction cable (34) that is roll upable at a rope hoist (38) actuated through a motor driving mechanism (42). The driving mechanism is controllable through a remote control device (44) at a scraper shovel (32). The driving mechanism comprises a driven shaft coupled with the rope hoist drivable with variable rotation speed, where the rotation speed is adjustable by a hand through the remote control device. A trick or shift controller is integrated in a handgrip (30) of the scraper shovel. #CMT#USE : #/CMT# Feeder for bulk material e.g. building material such as sand, gravel and fine concrete (all claimed). #CMT#ADVANTAGE : #/CMT# The driving mechanism comprises the driven shaft coupled with the rope hoist drivable with variable rotation speed, where the rotation speed is adjustable by the hand through the remote control device, thus ensuring easier handling during filling process, and reducing the risk of wear for the material and risk of injury. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective side view of a motor driven mixer for building materials with a bulk material feeder. 18 : Feeder 30 : Handgrip 32 : Scraper shovel 34 : Traction cable 38 : Rope hoist 42 : Motor driving mechanism 44 : Remote control device.
