Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, a construction waste crushing and recycling device in this embodiment includes an extrusion table, an extrusion crushing mechanism located above the extrusion table, and a rolling crushing mechanism located outside the extrusion table.

[0028] Extrusion platform comprises two bearing platforms 10, and the inner top of bearing platform 10 is fixed with electromagnet 11, and electromagnet 11 selects a piece of electromagnet roughly the same as bearing platform 10 area according to the area of ​​bearing platform 10. The top surfaces of the bearing platforms 10 are all arranged horizontally, the bottom surfaces of the bearing platforms 10 are all inclined, and the high ends of the two bearing platforms 10 are offset, that is, the two bearing platforms 10 are spliced ​​into an extrusion platform. A base 1 is installed below the bearing platform 10, and both sides below the bearing platform 10 are provided with an outer supporting co...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is: in this embodiment, the top of the inner support column 5 is rotatably connected with rollers, and the rollers are against the bottom surface of the bearing platform 10, and the bottom surface of the bearing platform 10 is supported by the rollers, which is convenient for the bearing platform 10 to move on. Swipe on the scroll wheel.

Abstract

The invention belongs to the field of building mechanical equipment, and particularly discloses a building construction waste crushing and recovering device. The building construction waste crushing and recovering device comprises an extrusion table, an extrusion crushing mechanism located above the extrusion table and a rolling crushing mechanism located on the outer side of the extrusion table;the extrusion table comprises two bearing tables, wherein magnetic parts are arranged at the tops in the bearing tables, the bottom faces of the bearing tables are obliquely arranged, and the high ends of the two bearing tables abut against each other; outer supporting columns and inner supporting columns are arranged below the bearing tables, wherein the outer supporting columns are hinged to theouter ends of the bearing tables, and the tops of the inner supporting columns abut against the middles of the bottom faces of the bearing tables, and the outer supporting columns can transversely slide relative to the inner supporting columns. Through adopting the building construction waste crushing and recovering device, concrete blocks with steel bars can be crushed.

Description

technical field [0001] The invention relates to the field of construction machinery and equipment, in particular to a crushing and recycling device for construction waste. Background technique [0002] Construction waste refers to the residual mud, slag, mud and other wastes generated during the construction, demolition and repair of various buildings and structures by construction units or individuals, as well as residents' decoration of houses. According to the sources, construction waste can be divided into five categories: land excavation, road excavation, old building demolition, building construction and building material production waste. [0003] Among them, waste concrete blocks are the main construction waste, and the processing method for waste concrete blocks is usually as follows: workers screen the construction waste through a sieve, leaving large pieces of waste on the sieve, and then workers pick out large pieces of waste concrete and put them into crushing ...
