Description
Technical field
The present invention relates to Architectural Equipment technical field more particularly to a kind of building waste fast-crushing devices.
Background technique
Building is the general name of building and structures, is people to meet social life needs, utilizes grasped object
Matter technological means, and the artificial environment created with certain scientific law, geomantic omen theory and aesthetic principle.Building waste refers to
Construction, unit in charge of construction or it is personal all kinds of buildings, structures, pipe network etc. are built, are laid with or removed, institute in reparative processes
Dregs, spoir, rejected material, remaining mud and other wastes of generation.With the progress and improvement of living standard of people's science and technology, building
The development of industry is getting faster, at the same build caused by rubbish be also it is more and more, building waste is not real rubbish,
But misplaced " gold " in place, many wastes in building waste are sorted, reject or crush after, can be used as mostly
Regenerated resources re-use.For example, the metals such as steel scrap muscle, waste iron wire, waste electric wire and various steel scrap accessories, sorted, collection is neutralized
Again it melts down；The waste materials such as brick, stone, concrete after crushing, can replace sand for masonry mortar, plastering mortar and concrete mats
Layer etc., can be also used for the building materials such as production building block, Paving bricks, lattice brick can also after coarse-fine aggregate addition solidifies class material
For highway road surface.
Currently, construction personnel is crushed using existing construction waste crusher when more for building waste, although
Existing crusher can carry out multiple stage crushing to various bulk materials, still, can generally produce in carrying out every grade of shattering process
Life after multiple stage crushing or cannot need manually to be cleared up by the building waste of sieve pore, not only bothersome laborious, energy consumption
Greatly, there is also security risks.When besides less for generation building waste, people are typically all that tool is used to be crushed,
Broken speed is extremely slow, and efficiency is very low, and degree of crushing is not high, for this reason, it may be necessary to propose that one kind is highly-safe, it is artificial broken without participating in
Broken building waste fast-crushing device.
108686799 A of patent CN, it discloses a kind of building waste apparatus for crushing and treating, including crush box, the throwings
The top of crush box is run through in material mouth bottom, and feeding port inner cavity is equipped with strong magnets, is provided with and adds below the strong magnets
Wet device, the humidifier right hand top are provided with connection hose, and the other end of the connection hose is on the right side of crush box
It is connect with water tank, and water tank is mounted in crush box outer right wall, is provided with the first pulverization cylinder below the humidifier, it is described
It is mounted on spring pedestal at left and right sides of crush box intracavity bottom, spring is installed at the top of the spring pedestal, the sieve is left
Lateral roof offers coarse fodder feed opening, and the crushing box bottom is provided with fines feed opening, the crushing box bottom left and right sides
It is provided with bracket.But the patent can only be crushed once, and need manual cleaning to the rubbish that cannot once crush, again
Device is put into be crushed, it is bothersome laborious.
108067321 A of patent CN discloses a kind of two-stage crushing building waste grinding device, including pedestal, the bottom
Separating twice chamber, a crushing chamber and feed hopper are disposed on seat from the bottom up, is equipped with and crushes in a crushing chamber
Roller, the separating twice chamber is disposed in the horizontal direction crushes plate and reclaiming plate, the reclaiming plate and separating twice chamber it
Between form surge chamber, the surge chamber side is provided with the collecting box being connected with surge chamber, the separating twice chamber and primary
It is provided with partition between crushing chamber, the feed opening of crushing chamber of connection and separating twice chamber is provided on the partition.Although
The scheme that the patent provides can crush building waste twice, still, for the building rubbish that cannot be all crushed to twice
Rubbish still needs artificial treatment, cannot be can not achieve by the building waste of sieve screen apertures and continue to crush in automatic return mechanism, peace
Full property is low, and construction efficiency is low, and energy consumption is high.
Summary of the invention
In view of the deficienciess of the prior art, making the technical problem to be solved by the invention is to provide a kind of practical
With conveniently, it is not necessarily to hand breaking, can will not pass through automatically and continue to crush in the building waste automatic return mechanism of sieve screen apertures, and
Quickly building waste can be crushed, the high building waste fast-crushing device of degree of crushing.
