The scraping plate mechanism of compression type garbage truck precompressor
Technical field
The utility model belongs to transporter components, is specifically related to a kind of scraping plate mechanism of compression type garbage truck precompressor.
Background technology
Compression type garbage truck can be with application of city life garbage, medical waste and other townm refuses, and compacting, the transportation of airtight, no water clock have realized that the safety and sanitation of townm refuse are cleared, and are used widely in recent years.Precompressor is connected the compartment afterbody of compression type garbage truck, and radical function is with fluffy garbage truck, is filled into the compartment then.The effect of scraping plate mechanism is to cooperate with sled mechanism, and rubbish is carried out compacting and reprints the compartment, makes junk take less delivery space as far as possible, to improve accumulating efficient.
The precompressor of compression type garbage truck, comprise casing, sled mechanism, scraping plate mechanism, sled mechanism comprises slide plate, sliding plate hydraulic cylinder, slide block, and slide block is captiveed joint with the slide plate side, slide block is arranged in the track of precompressor casing both sides, and the sliding plate hydraulic cylinder is arranged on the precompressor casing; Scraping plate mechanism comprises scraper plate, scraper plate hydraulic actuating cylinder, and scraper plate is hinged on the lower end of slide plate, and the scraper plate hydraulic actuating cylinder is arranged on the slide plate side.During operation, scraper plate Driven by Hydraulic Cylinder scraper plate is to certain angle, and the sliding plate hydraulic cylinder drives slide plate simultaneously, the drive scraper plate presses down simultaneously, under the combined action of slide plate, scraper plate, rubbish is compressed operation.Known scraping plate mechanism, its scraper plate is a planar structure, because of the precompressor track becomes 40 degree-60 degree angles with the cabin floor plane, scrape combined pressure when contracting rubbish scraper plate scrape and close inclination angle that makes progress of face normal direction and cabin floor formation, the compressive force degree of utilization is reduced, be difficult to the abundant compacting of rubbish.It is parallel with the bottom, compartment that scraper plate is scraped legal line direction, is that the compressive force degree of utilization is the highest, but because the planar structure of scraper plate is closed angle if adopt scraper plate to scrape legal line with compartment parallel the scraping in bottom, rubbish will be scattered from scraper edge, make the compression failure.
The utility model content
In order to overcome known technology field above shortcomings, the purpose of this utility model is, a kind of scraping plate mechanism of new type of compression formula waste-skip precompressor is provided, and compressive force utilization ratio height can be convenient to load fully with garbage truck.
The scraping plate mechanism of the compression type garbage truck precompressor that the utility model provides, comprise scraper plate, scraper plate hydraulic actuating cylinder, scraper plate and slide plate lower end hinge-coupled, scraper plate hydraulic actuating cylinder one end is arranged on the slide plate side, the other end is hinged on the scraper plate side, described scraper plate is a folding face structure, and its cross section is<shape or (shape or shape.
The scraping plate mechanism of the compression type garbage truck precompressor that the utility model provides, its beneficial effect are that scraper plate is a folding face structure, scrapes when closing rubbish, has improved the utilization ratio of compressive force, and fully with garbage truck, rubbish is scattered when preventing to compress simultaneously.
Description of drawings

1. compartment; 2. slide plate; 3. scraper plate hydraulic actuating cylinder; 4. precompressor casing; 5. scraper plate.
The specific embodiment
Below in conjunction with accompanying drawing, by an embodiment, the scraping plate mechanism of the compression type garbage truck precompressor that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1, the scraping plate mechanism of the compression type garbage truck precompressor of present embodiment, be arranged in the precompressor casing 4 of compression type garbage truck, comprise scraper plate 5, scraper plate hydraulic actuating cylinder 3, scraper plate 5 and slide plate 2 lower end hinge-coupled, scraper plate hydraulic actuating cylinder 3 one ends are arranged on slide plate 2 sides, and the other end is hinged on scraper plate 5 sides, described scraper plate 5 is a folding face structure, and its cross section is<shape.
During the compression operation, slide plate direction along ng a path under the driving of hydraulic actuating cylinder glides, scraper plate Driven by Hydraulic Cylinder folding face scraper plate upset simultaneously, when folding face scraper plate scrape legal line when parallel with the base plate in compartment 1, scraper plate is scraped pressure rubbish under the drive of slide plate, after being depressed into the position, slide plate stops, the effect of scraper plate hydraulic actuating cylinder, driving folding face scraper plate is inwardly scraped and is closed, and further rubbish is scraped combined pressure in fact.
