Description
Technical field
The present invention relates to technical field of engineering machinery, more particularly to a kind of land leveller.
Background technology
Land leveller is the earthmoving machinery using scraper ground grading, and scraper can lift, incline between wheel shaft before and after machinery
Tiltedly, it turns round and overhanging.Flexible movements are accurate, easy to operate, and smooth location has higher precision, suitable for constructing roadbed and road
Face builds side slope, excavates gutter, can also stir paving mix, clear away the snow, push bulk granular material and progress dirt road and broken
The maintenance work of Shi Lu.
After present land leveller upper rotary gear ring is connect with hitch frame, therebetween using direct using metal gasket and metal
Friction, filling butter lubrication, is easy bonded particulate sundries, causes to grind between two moving surfaces in this way, generates cut, movement resistance
Power is big, and height is required to the surface treatment of material, while needing often to add butter, generation environment pollution, increase routine work amount.
In order to solve the above-mentioned technical problem, a kind of level land mechanical shovel of the disclosure of the invention of Patent No. " 200720018938.1 "
The bindiny mechanism of knife hitch frame and gyration gear ring, referring to Figures 1 and 2 shown in, between gyration gear ring 6 and hitch frame 8 by seat 1,
Guide plate 9, wearing plate 7 and one group of adjusting pad 2 link together the two, and the increase and decrease by adjusting 2 quantity of pad adjusts gyration gear ring 6
It with the gap between wearing plate 7, is present on 1 and fixes wearing plate 4 with screw 3, wearing plate 5 is fixed in the screw 3 of guide plate inner face 9,
When gyration gear ring 6 does rotary motion relative to hitch frame 8 in this way, rub with the wearing plate 4,5,7 that oil-containing nylon material makes, it can
With lubricating movements face, friction is reduced.When gyration gear ring does rotary motion relative to hitch frame, pass through the oil-containing nylon material that rubs
The wearing plate of making achievees the purpose that lubricating movements face, reduces friction, Ke Yibao to avoid the direct friction between metal
The good motility of perching knife is demonstrate,proved, daily maintenance is exempted.
The apparatus for work of land leveller is to realize that the groundwork device of land leveller function in operation, needs reality as needed
360 degree of revolutions of existing turning circle.When rotation, the revolution of turning circle is sliding friction, and the wearing plate for installing special material is needed to make
For sliding friction contact, after abrasion, need that gap and replacement can be adjusted.
However the axial direction of the revolution between the turning circle and hitch frame of the invention of Patent No. " 200720018938.1 "
Wearing plate is non-adjustable structure, is directly installed on hitch frame, initially ensures that gap, abrasion need straight afterwards to a certain extent when installation
It connects replacement, or needs the position of integrated regulation turning circle to adjust gap, heavy workload, and adjustment difficulty is big, i.e., axial wearing plate
The gap of contact surface can not adjust or adjustment difficulty is larger.
