摘要： PURPOSE:To provide a crusher of simple construction in which the gathering and feeding of lumpy materials do not take much time and the lumpy materials are effectively crushed and in the case where materials, such as concrete lumps are crushed, they are effectively crushed. CONSTITUTION:A self-traveling shovel crusher scoops up lumpy materials on the ground in an arbitrary place with a bucket 23 by preferably displacing a boom, and the lumpy materials in the bucket 23 are crushed in a crusher part 22 provided with a fixed plate 24 and a movable plate 25. Thus the lumpy materials are effectively crushed on-site. The movable plate 25 is driven by a crusher hydraulic cylinder 30 to simplify its driving mechanism. The tooth height of a part of crushing teeth is increased on the inlet side of the crusher part 22 to effectively crush materials, such as concrete lumps.

摘要： PURPOSE:To obtain a large centrifugal force in a required direction by setting an inertia moment larger than the inertia moment including an eccentric weight body round the output shaft of a driven gear at the input shaft of a working gear for the output shaft of the driven gear provided with the eccentric weight body. CONSTITUTION:The input shaft 10A of the working gear 10 and the output shaft 11B of the driven gear 11 are deviated in the centers by a prescribed sized on a straight line connecting the centers of the working gear 10 and the driven gear 11 which are meshed with each other. An eccentric weight body 12 is provided round the output shaft 11B of the driven gear 11 and a flywheel 13 as the inertia moment larger than the total inertia moment including the eccentric weight body 12 at the output shaft 11B is set at the input shaft 10A so the working gear 10. A large centrifugal force of the prescribed direction is generated in a high-speed revolution fluctuation range during one revolution of the eccentric weight body 12 round the output shaft 11B in this way. Namely, the large centrifugal force is obtd. to the required direction from the output shaft without increasing the input torque of the input shaft 10A.

摘要： PROBLEM TO BE SOLVED: To effectively crush a material to be crushed to a granular material of small size without making a crusher a large-sized one. SOLUTION: This crusher is provided with a hopper 1 for feeding a material to be crushed, a crushing roller 4 freely rotatably supported below the hopper 1, a fixed plate 5 having a circular-arcuate crushing surface 20 extending downward along an outer peripheral surface 17 of the crushing roller 4, and a drive part consisting of an engine and the like to drive and rotate the crushing roller 4. Between the outer peripheral surface 17 of the crushing roller 4 and the crushing surface 20 of the fixed plate 5, a tapered clearance 14 is formed.

摘要： PURPOSE:To enable work to be easily executed by connecting a block retaining cylinder to the rear side surface of a bucket rear-plate and a bell crank, and by setting a block retaining device to be respectively confronted with the bucket rear-plate and the bell crank. CONSTITUTION:At the time of stone piling-up work, the boom mechanism of a stone piling-up device is moved, and a shovel bucket 20 is swung, and a block retaining device 45 is positioned on a block line. After that, a block retaining cylinder 48 is telescopically moved, and by a pipe 46 set at the rib 24 of a bucket rear-plate 21, and a pipe 47 set at a bell crank 41, a plurality of blocks are retained to be horizontally arranged. After that, the boom mechanism is moved, and is carried to a stone piling-up position on a slope surface, and the blocks are arranged manually by workers. Then, at the time of backfilling work, the bucket 20 is moved to scoop gravels or the like, and is moved to a space section between the slope surface and the blocks. Besides, a bucket opening or closing cylinder 35 is shortened, and a bucket main-body 30 is released to the rear plate 21, and the gravels or the like are fed to the space section.

摘要： PURPOSE:To facilitate masonry work and allow it to be done in a short time by fixing a block pinching tool to the bottom of a bucket rear plate and the bottom of a bell crank mating with it. CONSTITUTION:At the time of stone masonry work, a boom mechanism is moved in the condition that a pin P1 is removed, and a shovel bucket 20 is revolved by a hydraulic cylinder 27 to locate the pipe 61 of a block pinching device 60 in the row of blocks. Then another hydraulic cylinder 62 for expansion and contraction is expanded or contracted to pinch a plurality of blocks with pipes 61, 62 while the blocks are laid in transverse arrangement, and they are carried to a masonry position and put in rows and columns. At the time of back-fill works, the pin P1 is fitted while another P2 is removed, and the gravel, etc., is scooped by the bucket 20 and moved to over the space between the slope and blocks. Further the cylinder 63 is contracted, and the bucket body 30 is released to the bucket rear plate 21, and thus the gravels, etc., are supplied to the space.
