A mobile crushing system is for crushing inputted objects and dropping the crushed objects directly into an ore path. The mobile crushing system includes a crusher vehicle on which a crushing device for crushing the objects is mounted and which includes carriers, and a feeder vehicle on which a transfer device for transferring the objects to the crushing device and which includes carriers. The crusher vehicle and the feeder vehicle travel independently and include a crusher-side connecting portion and a feeder-side connecting portion that are connected to each other. During crushing operation, the ore path is interposed between the crusher vehicle and the feeder vehicle in the front-rear direction.

Self-propelled crushing system

A movable wood crushing machine according to the present invention comprises a vehicle bodywith a travel device provided therein; a rotary crushing deviceprovided at an edge of this vehicle body in the traveling direction for crushing the wood into wood chips; a tab-type feederprovided on this rotary crushing device with an charging opening for charging wood to be crushed formed in an upper section thereof; a conveyerextending from a position under the rotary crushing devicein the traveling direction of the vehicle body toward the other edge section of the vehicle body in the traveling direction for transferring and discharging wood chips crushed by the rotary crushing deviceto the outside; and a drive unitprovided between the rotary crushing deviceand the conveyerfor driving drive sources for the travel devicethe rotary crushing devicethe tab-type feederand the conveyer

Mobile wood crusher

A rotary crushing apparatus having a hydraulic motor for driving a crusher includes a load detector for detecting a loading state of the hydraulic motor, a load judging device for judging the loading state of the hydraulic motor, a feeding amount controller that stops a feeding of an object to be crushed by a feeder when the load judging device judges as overloaded or that starts the feeding of the object to be crushed by the feeder when the load judging device judges as underloaded, and a motor capacity controller that changes a capacity of a capacity-variable motor to a large capacity when the load judging device judges as overloaded. Since the capacity of the hydraulic motor is switched to the large capacity when the feeder is stopped, it is possible to crush wood in the crusher with high torque and to reduce the load in order to recover to a former state in a short time.

Crushing apparatus

A travel control device of a self-propelled recycle machine includes: a mode selection meansadapted to select a work mode and a travel mode; a travel operation means for operating a drive of a base carrier, and a controller for controlling drives of the base carrier and a crusher or a soil improvement machine, the controller including: a mode judging meansfor judging a mode selected by the mode selection means; a travel operation signal detecting meansfor detecting a travel operation signal from the travel operation means; and a work mode control meansfor controlling the drive of the base carrier, when it is judged that the work mode is selected and when the travel operation signal is detected, based on the travel operation signal while driving the crusher or the soil improvement machine.

Travel control device for self-propelled recycle machine

The invention provides a mobile crushing apparatus which is compact and light, has an improved assembling property and maintaining property, and has an improved operability for changing to a traveling attitude. Accordingly, in the apparatus provided with a crusher ( ) crushing rocks or the like and a supply conveyor ( ) for supplying a material to be crushed, which are mounted on a frame ( ), the supply conveyor is provided in one side in a width direction of the frame, and an input shaft ( ) for inputting a driving power to the crusher is provided in another side in the width direction of the frame. A power source ( ) for the crusher and the supply conveyor is arranged in a stand ( ) so as to constitute a power unit ( ) and mounted to the frame via the stand.
