Fig. 1 is the structural representation of half-closed snow-removing device of the present invention.
Fig. 2 is the drive mechanism schematic diagram of half-closed snow-removing device of the present invention.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect for making the present invention realize are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
Referring to Fig. 1 and Fig. 2, a kind of half-closed snow-removing device of the present invention, including support 1, snow-removing device fixed plate
2nd, rotating shaft 3, sprocket wheel 4, driving-chain 5, scraper stent 6, scraper plate 7, counterweight 8, gear 9, gear 10, rotating shaft 11, minor sprocket 12, transmission
Chain 13, rotary shaft 14, handle 15, fixed plate 16, upper chain baffle plate 17, lubricating oil groove 18, gear-box 19 and chain case 20.
The present invention is to plan using a kind of more efficient doctoring technique for carrying out agricultural facility in mentality of designing
Accumulated snow removal work, its power source was both easier to maintenance by the way of manpower rotation, and it is raw more to meet China's agricultural
Practical situation in product and economic benefit.The present invention takes certain guarantor for the service life of extension fixture to drive mechanism
Shield design, adopts half-closed structure to the upper driving chain mechanism driving snow-removing mechanism work, for travelling gear and underdrive chain
Structure adopts closed structure.
Whole snow removing assembly is fixedly mounted on the over top of agricultural facility by the present invention by snow-removing device support 1, and
By the accumulated snow moving back and forth removal installation atop of scraper plate 7.Rotating shaft 3 in the present invention, sprocket wheel 4, driving-chain 5, scraper stent 6,
Scraper plate 7 and counterweight 8 composition Chain conveyer accumulated snow scraper assembly, gear 9, gear 10, rotating shaft 11, minor sprocket 12, driving-chain 13, rotation
Axle 14 and handle 15 composition power transfer assembly.Two rotating shafts 3 are separately mounted to the upper and lower ends of snow-removing device fixed plate 2,
The two ends of rotating shaft 3 are installed with sprocket wheel 4, are separately installed with driving-chain 5, the two ends of driving-chain 5 are divided on the sprocket wheel 4 of two groups of left and right
Do not connected by pin, thus forming it into chain link with scraper stent 6.In 6 times fixed installation scraper plates 7 of scraper stent, in scraper plate
Support 6 top design fixed weight 8, relies on counterweight 8 to provide certain gravity, makes driving-chain tensioning.Above left and right driving-chain 5
Chain baffle plate 17 is installed, sprocket wheel 4 envisaged underneath in oblique lower end has lubricating oil groove 18, provides effectively for driving-chain 5
About lubrication.It is installed with gear 9 in rotating shaft 3 middle of downside.Gear 10 is engaged with gear 9, and gear 10 is pacified with gear 9
