Problems solved by technology

However, as the function of the cover, most of them are simple structures to prevent the scattering of ground materials, and cannot reliably prevent the scattering of ground materials.
[0015] In addition, because the raw material is not gradually supplied to the crushing chamber of the bucket according to the crushing capacity of the bucket, there is a possibility that the drive motor or the power transmission part is in an overloaded state, causing a failure of the drive motor, etc.

Abstract

The present invention relates to a crushing lid which has a function of crushing a raw material put into a bucket, performs an opening and closing movement interlocked with an oscillatory movement about the spindle of the bucket, and has a simple structure. A bucket body swingably installed on the tip end of an arm of an civil engineering machine and having an opening for charging a raw material is provided with a swingingly-opened / closed movable lid. The crushing lid is opened / closed by lid-interlocking opening / closing means in interlock with the swinging motion of the bucket body. The raw material charged through the opening is crushed with a resilient plate and a rotor installed in the inside of a movable wall.

Description

technical field [0001] The present invention relates to a bucket with a crushing cover which is mounted on the front end of an arm of a civil engineering machine and has a crushing function for crushing raw materials and a crushing method thereof. The pulverizing cover is linked with the swing action of the bucket main body, and the bucket with the pulverizing cover is opened and closed, and the pulverizing method thereof. technical background [0002] There is a social problem in that a large amount of various industrial wastes represented by asphalt slag and concrete waste are discharged during road maintenance, building demolition, and the like. In the past, most of them were disposed of in landfills, but now they are often reused from the viewpoint of environmental protection. In particular, waste materials such as concrete have a large amount and can be basically reused, so their reuse is strongly desired. [0003] The buckets of civil engineering machinery that direc...
