伸縮可能とした掘削機にツインドラム型の切削ドラムを
取付けることは不可能であった。However, in the twin-drum type, the reducer that drives the twin cutting drums must be built into the cutting drum or placed immediately in front of it, so it is necessary to install the twin-drum type in an excavator with extendable cutting drums. It was not possible to install a mold cutting drum.

It is necessary to apply a large transmission torque to the spline shaft to enable the cutting drum to cut hard rocks, etc., and accordingly, the structure of the transmission mechanism has become stronger and larger to withstand this torque, and the prime mover has also had a high output. The installation cost $7, which increased equipment downtime and increased the weight, which hindered workability in narrow tunnels, mine shafts, etc.

。5 is a slide tube, and the support! ! At the same time, a hydraulic cylinder 6 is installed between the one-node boat cylinder 4 and the slide cylinder 5, and the slide cylinder 5 is attached 47 so as to be movable. Reference numeral 7 denotes a reducer, which is attached to the tip of the slide tube 5, and a cutting doshim 8 is attached to the reducer 7 in a detachable and replaceable manner.
Install it. This cutting drum 8 may be of a twin drum type as shown in FIG. g:J1 and FIG. 2, or may be of a single drum type as shown in FIG. 3. 9 is a transmission mechanism,
Consists of a hollow expansion joint 10 and a spline shaft 11,
The base end side of the expansion joint 10 is fixedly connected to the output shaft 12 of the driving force 113, and a spline groove 1 formed on the distal end side.
3 by fitting the teeth 14 of the spline shaft 11 to freely attach the spline shaft 11 to WlvJ, and fixedly connect one end of the spline shaft 11 to the input shaft 15 of the deceleration mV.

供できる効果を有するものである。As described below and in detail with respect to the embodiments, the present invention includes a cutting drum that is extendably attached to the foot frame on the main body side,
The prime mover is attached to the base frame side, the reducer is attached to the cutting drum side, and the original vJ11 is connected to the reducer by a telescoping transmission mechanism, so the transfer torque of the driving force from the prime mover is small. Powerful torque capable of cutting even hard rocks can be transmitted to the cutting drum, and the entire structure can be made lightweight and compact. Furthermore, it is possible to install a twin-drum type cutting drum, which could not be installed using the conventional mechanism, so it is extremely easy to use, as it can be changed to a single-drum type or twin-drum type depending on the situation at the work site. This has the effect of providing an excellent excavator.
