As described above, when a third person approaches, a plurality of operations of switches provided separately for instructing a sound of a horn, a stop of rotation of the tub 2 and a stop of rotation of the crusher 3 are required. Since it takes a long time to get on and off the loader 23 and to reciprocate between the loader 23 and the wood crusher 1 just to remove the pieces or the like sandwiched between the
No. 1 has a problem that operability is not good.

An object of the present invention is to provide a control device with good operability of a wood crusher, focusing on the above-mentioned problems of the prior art.

[0007]

Means for Solving the Problems, Functions and Effects In order to achieve the above object, a first invention is a wood crushing machine provided with a rotary tub for supplying crushed material and a crusher for crushing the crushed material. The control device of the machine is provided with a switch for simultaneously instructing the warning horn to sound and the tab to stop rotating.

According to the first aspect of the present invention, just by operating the switch, a warning horn sounds to warn a third person approaching the crushing device, and at the same time, rotation of the tub is stopped to crush the crushed object. Since the supply of the material to the crusher stops and the material is not crushed, scattering of the crushed material to the outside of the tub is reduced. Thus, the alarm horn is sounded by the single alarm horn sounding switch, and it is possible to prevent the alarm horn from approaching the crushing device of the third party. Even if the warning horn is sounded, the operability is improved because the complicated operation of stopping the rotation of the tab by operating another tab rotation stop switch is unnecessary for the safety of a third person who comes closer to the crushing device even if the horn is sounded. .

In a second aspect based on the first aspect, the switch for simultaneously instructing the alarm horn to sound and the tab rotation to be stopped is of a remote control type.

According to the second aspect of the present invention, since the remote controller is used, the operator of the loader can operate the switch, and the operator of the loader can monitor work alone. Furthermore, the operator of the loader can monitor a wide range from the high cab of the loader, and it is easy to monitor the approach of a third party.

A third invention is based on the first or second invention, wherein the switch for simultaneously instructing the sounding of the warning horn and the stop of the rotation of the tub simultaneously instructs the stop of the rotation of the crusher.

According to the third invention, when the switch is operated, a warning horn sounds and not only the rotation of the tab but also the rotation of the crusher is stopped. Thereby, three operations can be performed simultaneously, and the operability is further improved. In addition, since the supply and the crushing of the crushed material are completely stopped, the crushed material is not scattered at all.

[0013] A fourth aspect of the present invention provides a rotary tab for supplying crushed material,
In a control device of a wood crusher having a crusher for crushing a crushed object, a scatter prevention cover covering at least a part of a crushed material input port of a rotating tab, an opening / closing mechanism for opening and closing the scatter prevention cover, and a remote controller And an anti-scatter cover open / close switch.

According to the fourth aspect of the invention, the scattering prevention cover provided to prevent the crushed material from scattering outside the tub covers at least a part of the crushed material input port of the tub. For this reason, put the crushed object in the gap between the shatterproof cover and the tab,
Alternatively, the rotary tub may be clogged and the crushed material may not be supplied to the crusher. In this case, the operator of the loader operates the switch on the loader side to open and close the scattering prevention cover without operating the switch on the operation panel of the wood crusher after getting off the loader, and opening and closing the scattering prevention cover. Crushed or clogged objects can be easily removed. Thereby, a control device with good operability is obtained. In addition, from the operator's cab of the loading machine at a high position, the crushed material can be easily monitored for pinching and clogging,
Immediate release is also possible, thus preventing interruption of work and occurrence of equipment failure.
