爪である。Next, the lower frame 1 will be described with reference to FIGS. The front portions of the left and right side frames 1a, 1a of the lower frame 1 are joined by welding a highly rigid front frame 1b, and a plurality of front frames 1b between the side frames 1a, 1a are provided behind the front frame 1b. Horizontal frame 1c ~
1e and a rear frame 1f are welded, and vertical frames 1g to 1i are welded to the front frame 1b to the horizontal frame 1e in an intersecting manner, whereby the crushing surface is formed in a lattice shape. 1j is a claw attached to the front end of the lower frame 1.

なわち前後方向の中央部が凹んだ形状をなしている。As shown in FIG. 1, the horizontal frames 1c to 1e are bowl-shaped with the crushing surface being the upper surface recessed in the center, and the vertical frames 1g to 1i have the crushing surface lower by ΔH than the side frame 1a. Has been formed. In addition, as shown in FIG. 2, the line 1 formed on the upper surface (crushing surface) of the front frame 1b or the horizontal frames 1c to 1e forms an arc, that is, the central portion in the front-rear direction is recessed. ing.

は、破砕面を前後方向についても凹型に形成しているの
で、被破砕物が前後よりもれることも防止され、より破
砕効率が向上する。In this way, the crushing surface of the lower frame 1 has a structure in which the center in the width direction is recessed, so that the crushed object such as concrete or stone is sandwiched between the upper and lower frames 1 and 2, and the hydraulic cylinder 4
When crushing by extending, the crushed object is prevented from spilling outward, and the crushing surface is pushed toward the center of the lower frame 1 in the width direction and crushed with a good balance of left and right, so crushing efficiency is improved. However, it becomes possible to crush a large amount of crushed objects at one time. Further, in the present embodiment, since the crushing surface is formed in a concave shape in the front-back direction as well, the crushed object is prevented from leaking from the front and rear, and the crushing efficiency is further improved.
また、本実施例のものは、下フレーム１の破砕部が格子

効果が得られる。Further, in the case of this embodiment, since the crushing portion of the lower frame 1 has a lattice shape, the crushed small blocks fall from the lattice portion, so that the lower frame 1 also functions as a sieve.
Therefore, the vertical and horizontal dimensions of the opening formed by this grid
By making it about 8 cm to 12 cm, a block with a diameter of about 10 cm suitable as a paving stone after crushing concrete can be obtained by crushing work without using a sieve, and the effect of 1 bird and 2 birds can be obtained.
