Embodiment Construction

[0035] Referring first to FIG. 1 , a bucket for crushing inert material, such as waste from building demolition or excavation, is generally indicated by the reference numeral 100 . Such a bucket is of the type suitable to be fitted, by means of a web 5 or other equivalent attachment means, to a movable arm of an operating machine not shown in the figures.

[0036] The bucket 100 comprises an outer housing 1 inside which a crushing unit 3 is arranged, which is shown schematically in the figure.

[0037] The crushing unit 3 is arranged inside a feed channel 101 for the material to be crushed, along which a feed direction A is defined and substantially parallel to the direction of the longitudinal extension of the bucket.

[0038] Furthermore, according to a preferred embodiment, the crushing unit 3 is of the jaw type and comprises at least one movable jaw 31 preferably associated with a fixed jaw 32 and along the Alternately moving in a crushing direction C which is substantial...

Abstract

A bucket (100) for crushing inert materials, the bucket comprising an outer casing (1), a feeding part (10) as well as a crushing unit (3) and a screening device (2), the feeding part It is used to make the material to be crushed enter into the casing (1), and the crushing unit is arranged in the casing (1) to crush the material, and the screening device is used to screen the material to be crushed and is arranged in Midway between the feed hole (10) and the crushing unit (3). The screening device (2) comprises at least one rotating member (20), the partial rotation of which is adapted to screen a portion of the material to be crushed whose size is below a predetermined size.

Description

technical field [0001] The invention relates to a bucket comprising inert material for screening and crushing. Background technique [0002] In the technical field involved, buckets are known which can be applied to the end of the arm of a handling machine and which comprise an outer casing, the handling machine being configured to collect debris such as material such as inert material, and is equipped inside the operating machine with means for crushing the collected material. [0003] An example of a bucket of this type is described in European patent EP 1532321, wherein the bucket has the shape of a shovel and the crushing means are implemented by pairs of jaws which act with alternating movements on the on the material. [0004] Also defined in these buckets are holes for the material to be crushed, inside which material is jammed by causing the buckets to perform the function of a collecting scoop by means of suitable movements of the arms operating the machine.
