Lifting garbage compressor
Technical field:
The invention belongs to the urban sanitation equipment technical field, be specifically related to a kind of lifting garbage compressor.
Background technology:
At present, lifting garbage compressor has Chinese patent application numbers 200810062297.9, publication number CN10298195A; A kind of " buried type garbage compressor " of being made up of dustbin, compressing mechanism, ejecting mechanism and lifting device disclosed, its lifting device adopts lift cylinder to realize the rising or the decline of dustbin, lift cylinder is installed on the melt pit basis, drive the lifting of rubbish casing on the pin joint upgrade block of oil cylinder termination, this structures shape the hoisting depth of casing must equate promptly 1: 1 with oil cylinder stroke, and the height of column will be twice in hoisting depth or oil cylinder stroke at least.The weak point of this lifting device is: the first, and oil cylinder places inconvenient maintenance in the melt pit; The second, complex structure; The 3rd, the building height that defines factory building also must satisfy the height that is twice in oil cylinder stroke or is twice in lifting simultaneously, does not have the leeway that reduces height again.Also has China Patent No. ZL200420068109.0, Granted publication CN2707731Y; Disclose a kind of by hydraulic system, supporting frame, the oil cylinder of " garbage compression station synchronous hoisting device " this synchronous hoisting device of steel wire rope---compositions such as pulley is fixed on support frame one end, by the flexible steel wire rope of fixing its head that drives of piston, steel wire rope is centered on be fixed in the fixed pulley of four jiaos of frameworks, the suspension hook and the casing thereof that tie up to the rope other end are promoted or put down, hoisting depth and piston stroke also are 1: 1, the weak point of this lifting device is: it is fixed on the top of four root posts, self has just increased spatial altitude, is no more than 3 meters occasion use so be specially adapted to hoisting depth.
" buried type garbage compressor " is though its ejecting mechanism and compressing mechanism are respectively arranged with ejection cylinder and compression cylinder, but shared one of cut somebody's hair (pushing away platform) and pressure head, and the end face of cutting somebody's hair is consistent with the dustbin cross section, be that gross area compression and gross area are released, only when compression, finish compression work by cutting somebody's hair in " compression mount " motion of the back of cutting somebody's hair by " inconsistent roof pressure ", in the time of compression movement, the ejection cylinder of " being installed on the compression mount " is a companion motion also.The weak point of this ejecting mechanism and compressing mechanism: the one, gross area and total travel compression, need oil cylinder power big, moreover, rubbish is poured back bulk weight (as building waste) into and is fallen into earlier at the bottom of the case, pours into more still, after compressing repeatedly, the bottom weight is compacted, hinder pressure head and further compress, the close down thin phenomenon that can occur, rubbish piece integral body is unreal; The 2nd, connected mode complexity between the mechanism; The 3rd, the compression cylinder stroke is long, is bearing ejection cylinder merit in vain, and consumption of power wastes energy.
Summary of the invention:
An object of the present invention is to provide a kind of lifting device of lifting garbage compressor, make its hoist cylinder stroke short, hoisting depth is long, hoisting velocity is fast, and high efficiency is simple in structure, easy to maintenance, can obviously reduce the building height of the height and the factory building of column; Another object of the present invention provides a kind of compressing mechanism and ejecting mechanism of lifting garbage compressor, its pressure head is worked independently on cut somebody's hair, carry out small size, short stroke compression, then release the close down problem of dredging compression inequality, complex structure and wasting energy that goes up of solution with the gross area of cutting somebody's hair.
