    • PROBLEM TO BE SOLVED: To provide a crushing device which is of such a construction that small and uniform-size crushed pieces can be obtained without sorting the pieces out by a sieve. SOLUTION: In the crushing device which crushes a material to be crushed such as a wood while crushed pieces are stirred by rotary crushing means 4, 5 housed in an enclosure 3, a sieving member 22 which prevents the crushed pieces of a larger size than specified from passing through, is provided on the discharge aperture side of the rotary crushing means 4, 5. Especially the sieving member has a freely expandable/contractable sieve mesh for making the size of the crushed piece to be discharged adjustable. In concrete terms, the sieving member comprises a pair of porous plates 23, 25, superposed over each other in a freely slidable manner, the pores of which are mutually deviated to expand and contract the sieve mesh. In addition, the sieving member is freely attachable to and detachable from the arm of a hydraulic arm.

    • PROBLEM TO BE SOLVED: To provide an excavating device constituted to efficiently excavate whil-e discharging excavated sediment smoothly to the ground surface and to obtain the fine finish of a ditch dug up particularly in the use of culvert burying or the like while being capable of skillfully digging out Chinese yams without damaging them in harvesting the Chinese yams. SOLUTION: A plow body 3 is fitted to a base machine and advanced in one direction to excavate soil into narrow ditch shape. The plow body 3 has a cutting part 5 formed in channel shape at the front end; a guide face 9 inclining upward to the rear to push up sediment cut off by the cutting part 5; and a side face discharge opening 10 for discharging the sediment pushed up by the guide face 9, toward ditch shoulders. A sediment discharge member 21 for delivering the sediment pushed up from the cutting part 5, from the side face discharge opening 10 while reversing the sediment is particularly provided on the rear side of the guide face 9.

    • PROBLEM TO BE SOLVED: To provide a container tilting device for tilting a minor capacity container for temporary storage of any objects over a large capacity container, transferring the contained objects for collection, capable of easy and effective execution of operation, and allowing a transfer even in a working yard with a low ceiling. SOLUTION: A container tilting device is composed of a base machine due to a self-mobile vehicle equipped with an elevating/sinking function and an attachment 15A for tilting to be mounted in the elevation part 10 of the base machine, wherein the attachment 15A is equipped with a mounting and supporting part 16 whose base end is attached to the elevation part 10 of the base machine, an inversive dumping part 17 furnished with an engaging and retaining means for a container 2 for temporary storage and pivoted at the forefront of the mounting and supporting part 16, and an inversive driving means 27 interposed between the two parts 16 and 17 and generating swinging rotation along the locus in circular arc over the pivotal point where the inversive dumping part 17 is pivoted on the mounting and supporting part 16.

    • PURPOSE:To improve operability without increasing the manufacturing cost. CONSTITUTION:This coupler 1 for an attachment is provided with a main body fitting section 3 pivotally fitted to the machine main body side containing an attachment driving main hydraulic cylinder in advance and an attachment fitting section 5 having a pair of hooks 9, 10 holding a pair of pins arranged in parallel on the attachment side. A pair of hooks 9, 10 are a fixed hook and a movable hook driven by an auxiliary hydraulic cylinder 11. An auxiliary hydraulic feed pipe 28 to the auxiliary hydraulic cylinder 11 is branched from a main hydraulic feed pipe to the main hydraulic cylinder. The oil chamber 30 of the auxiliary hydraulic cylinder 11 and the auxiliary hydraulic feed pipe 28 are selectively communicated with output ports by a three-way selector valve 29 provided with check valves 31, 31 respectively.

    • PURPOSE:To switch excavating work and a condition suitable for grabbing-up work simply to/from each other by connecting a bucket rotated and driven by a hydraulic cylinder to the arm tip through a four-node link, fixing pivotally one end of a fork to an intermediate part of a link member, and switching a support angle by a stopper means. CONSTITUTION:A lever 6 is rotated by extension and contraction of a bucket cylinder 8 of a four-node link mechanism 10, and it is transmitted to a side plate 5 through a connecting link 7, and a bucket 2 is rotated. Next, one end of a fork 3 is pivotally fixed to a central part of the connecting link 7. An arm 4 is situated between a central mountable-demountable stopper pin 11 on the link 7 and either one of fixed stopper pins 12 and 13, and a support angle of the fork 3 is selectively set in two positions. Thereby, a front attachment can cope easily with a difference in the work content by simple operation, and can be also manufactured at low cost.
