Abstract
The utility model discloses a chain ditcher. The chain ditcher comprises a rack, wherein a hydraulic lifting arm is hinged with the rack; a large arm is connected to the lower end of the hydraulic lifting arm; the rear end of the large arm is connected to the rack by virtue of a transmission shaft; ditching chain wheels corresponding to each other are arranged on the transmission shaft and the front end of the large beam; a soil splitting chain wheel is arranged below the large arm; transmission chains are arranged on two ditching chain wheels and the soil splitting chain wheel; ditching cutters are fixedly arranged on the transmission chain wheels. The chain ditcher is characterized in that tensioning wheel and a protective cover are arranged above the large arm; the tensioning wheel is used for supporting the transmission chains; the ditching cutters are covered with the protective cover; one end of the protective cover is fixedly arranged on the large arm, and the other end of the protective cover is extended to the front end of the large arm; a soil scraping plate is arranged at the extension rear end; the rack consists of two square pipe support posts; inner pins of the two square pipe support posts are connected with telescopic support legs. The chain ditcher is relatively reasonable, safe and reliable in structural design, so that the problems of high chain dropping possibility, poor safety and inconvenience for installation and use of the existing ditcher are solved.
Description
Technical field
The utility model relates to farm machinery, particularly a kind of chain ditcher.
Background technology
Existing chain ditcher comprises frame, in frame, be hinged with hydraulic lifting arm, hydraulic lifting arm lower end is connected with large arm, large arm rear end is connected with frame by power transmission shaft, power transmission shaft is equipped with trench digging sprocket wheel with large arm front end, large arm below is provided with a minute catena wheel, two trench digging sprocket wheels and a minute catena wheel are provided with driving chain, on driving chain, be welded with ditching knife, thereby its angle by the large arm of hydraulic lifting arm adjustment is controlled ditching depth, accelerated to a certain extent trench digging speed, strengthened trench digging intensity, but still there are the following problems: 1, in driving chain operation process, stressedly can easily from sprocket wheel, drop when larger, also easily depart from trench digging track, have a strong impact on trench digging efficiency and trench digging quality.2, there is unsafe factor in exposed sprocket wheel, also easily when revolution by the earth backfill of excavation, impact trench digging quality.While 3, using, need this ditching machine to be connected with tractor traction apparatus, but because ditching machine volume is larger, weight is heavier, while lifting frame, requires great effort very much, needs several individuals to coordinate simultaneously, very inconvenient.4, ditching knife and driving chain are welded and fixed, and are unfavorable for changing cutter according to actual working environment or blade damage.
Summary of the invention
The purpose of this utility model is in order to provide a kind of structural design more reasonable, safe and reliable chain ditcher, and to solve, the chain that existing ditching machine exists easily drops, poor stability, install and use inconvenient problem.
The technical solution of the utility model is:
A kind of chain ditcher, comprise frame, in frame, be hinged with hydraulic lifting arm, hydraulic lifting arm lower end is connected with large arm, large arm rear end is connected with frame by power transmission shaft, power transmission shaft is provided with mutual corresponding trench digging sprocket wheel with large arm front end, large arm below is provided with a minute catena wheel, two trench digging sprocket wheels are provided with driving chain with a minute catena wheel, on driving chain, be fixed with ditching knife, it is characterized in that: described large arm top is provided with the regulating wheel that is supporting described driving chain and the protective cover that covers described ditching knife, described protective cover one end is fixed on described large arm, the other end extends and is provided with clean-up scraper at extending end to large arm front end, described frame is comprised of two square tube posts, the domestic telescopic leg that is connected with of described square tube post.
Above-mentioned chain ditcher, described ditching knife and driving chain profit are joined with bolts, to realize the object being convenient for changing.
The beneficial effects of the utility model are:
1, owing to above large arm, the regulating wheel that is supporting driving chain being set, significantly improve the tensile force of driving chain, can from sprocket wheel, not split away off easily, also avoided the trench digging track of ditching knife to depart from, improved trench digging efficiency and trench digging quality.
2, because large arm top is provided with the protective cover that covers described ditching knife, and be provided with clean-up scraper at the extending end of protective cover, avoided ditching knife to produce injury to staff, and protective cover and clean-up scraper are used in conjunction with and have prevented trench digging earthen backfill.
3, due to the domestic telescopic leg that is connected with of square tube post of frame, therefore while wanting to be connected with tractor traction apparatus, telescopic leg is propped up to its kiss the earth fixing of sening as an envoy to, facilitated frame has been connected with tractor, saved manpower.
