Description

The anti-skidding anti-chain rail device that falls into

The utility model relates to trac. and the matching used a kind of accessory machinery of various crawler type field machine, particularly a kind of anti-skidding anti-chain rail device that falls into.

Field machine is agricultural harvesting machine especially, the chain rail device of its crawler body, when number carrying out operation on the serious operation of low country, marshy area and damage caused by waterlogging ground, be absorbed in the earth easily, and it can't fall back when sinking to certain depth (about 40 centimetres) at all, at this moment is into can not advance, move back and to move back, have a strong impact on production.The reason that causes this situation is that the track (shoe) of chain rail device or caterpillar block and ground almost are plane contact, its anti-skidding anti-poor performance that falls into.Anti-track (shoe) and the cast type caterpillar block (disclosed as Chinese patent CN92242267.2 number) of falling into of compound type appearred at present, the former adopts manganese steel plate to combine with chain link after drawing, main deficiency is the cost height, service life is short, maintenance and replacing are comparatively complicated, no matter therefore the service expenditure height still said not ideal from the angle of economic benefit from result of use; The latter adopts the casting of M13 material to form, compare with the former, though it is low to have cost, increase service life, changes outside the characteristics such as more convenient, because it is unreasonable on its planform, especially the ground lug unreasonable structure causes desliming bad, and the coefficient that skids is too high, operation does not steadily wait not enough, thereby causes the mechanical work effect bad.In addition, the existing anti-skidding anti-big cover that falls into chain rail device is arranged on the center of each caterpillar wheel, thus bogie the elevation angle is big in the course of the work, the track (shoe) earth-catching property is poor, its coefficient that skids increases, and has reduced speed of advance, machine work efficient is lower.

The purpose of this utility model is: design provides a kind of simple in structure, long service life, and cost is low, and desliming is effective, mechanical work efficient height, anti-skidding anti-falling into, strong to soil condition adaptive capacity, the easy to maintenance anti-skidding anti-chain rail device that falls into.

The utility model is achieved by following manner: a kind of anti-skidding anti-chain rail device that falls into, comprise the anti-skidding anti-mechanism that falls into of bearing bogie frame 19 and supporting device thereof and driving walking, wherein, bogie frame 19 is welded by the backplate 14 of crossbeam 26 and big cover 15 that upward is provided with and big cover 15 both sides, drive the anti-skidding anti-mechanism that falls into of walking by drive wheel 25, guide wheel 10 that bogie frame 19 front and back and bottom are provided with respectively and caterpillar wheel 18 and form around above-mentioned each wheel and the anti-skidding anti-track (shoe) 14 that falls into that forms the triangle sealed joint, simultaneously, at the guide wheel 10 (guide wheel 10 in Fig. 1 left side, guide wheel 10 promptly, the right side is left guide wheel) bogie frame 19 be provided with the adjustment screw body, it comprises steel tank bevelled washer 11, adjust lower bolster 9, adjust arm-tie 8, adjust leading screw 12, screw set 7 and nut 13 are formed, in addition, supporting device is by major semiaxis 21, semi-minor axis 28, central support 29, side stand 30, U type clip 8, side stand fixed block 24, pole 3 compositions such as grade, feature of the present utility model is: the big cover 15 on crossbeam 26 tops of said bogie frame 19 adopts eccentric the setting, and the center of promptly big cover 15 moves forward between the 2nd and the 3rd caterpillar wheel 18 of caterpillar wheel 18 working direction; The action of gravity point that the reaper that can make on the big cover 15 that is installed in bogie frame 19 is set like this is in inclined to one side front position, to reduce bogie frame 19 elevation angle in the course of the work, can increase earth-catching property like this, reduced the coefficient that skids, improve the reaper speed of advance, thereby improved work efficiency.

Said anti-skidding anti-track (shoe) 14 is arranged with caterpillar wheel runway 37 and two ends thereof along its line of centers both sides the guide wall 35 that falls into, wherein, guide wall 35 is designed to the circular arc of projection, track (shoe) 14 rear axle housings 36 periphery lower ends are designed to the circular arc camber 39 that drive wheel 25 drives simultaneously, the side that the simultaneously anti-skidding anti-lengthening wing 33 that falls into track (shoe) 14 contacts with ground is provided with the anti-skidding arc-shaped curved surface 38 of an end projection along its length direction off-centre, with these the anti-skidding arc-shaped curved surface 38 rightabout lengthening wing 33 other ends then be corresponding groove 34, the principal feature of above-mentioned each parts is:

Caterpillar wheel runway 37 is the caterpillar wheels 10 that are used for supporting trac. or cover the crawler body of belt field machine, and guarantees that caterpillar wheel 10 rolls on straight runway; Guide wall 35 is the centres that are positioned at two caterpillar wheel runways 37, mainly is to avoid caterpillar wheel 10 laterally to slide out existing derailment occurring on track (shoe) 14; Front shaft sleeve 32 is to be used for the usefulness that each track (shoe) 14 is connected with rear axle housing 36, can each track (shoe) 14 be linked together by master track pin; The circular arc camber 29 that drive wheel 25 drives is parts of drive wheel 25 and track (shoe) 14 direct contacts when the drive wheel chain movement; The lengthening wing 33 mainly is to increase track (shoe) 14 and ground-surface area of contact, reduce pressure, to improve the anti-performance that falls into, the lengthening wing of track (shoe) originally be flat and the surface on the diagonal angle supporting rib is arranged, be absorbed in the mud easily, result of use is bad, and the lengthening wing 33 of present technique is the anti-skidding arc-shaped curved surface 38 along an eccentric setting of line of centers and an end projection, solved above-mentioned deficiency, this anti-skidding arc-shaped curved surface 38 at first contacts with ground during its work, and extruding ground also produces horizontal impression, increases track (shoe) 14 and ground-surface friction drag, reduce the coefficient that skids, in addition, the design of the eccentric swept-out of this anti-skidding arc-shaped curved surface 38 can make track (shoe) 14 self desliming, i.e. track (shoe) 14 own self-cleanings, guarantee this anti-skidding arc-shaped curved surface 38 depth of indentation on the ground, to obtain the stable coefficient that skids.

The axle of said caterpillar wheel 18 is provided with shaft sealing mechanism on 17, its by the capsul 44 that is arranged at caterpillar wheel 18 outsides and interior left and right seal ring 46 thereof and 45 and large and small flexible rubber ring 42 and 41, outermost seal receptacle 47 and on O type circle 40 form.The fitting process of sealing device is: at first little flexible rubber ring 41 is enclosed within on the seal ring 46, the two is fitted in the sealed support 47 then, then big flexible rubber ring 42 is enclosed within on the seal ring 45, they are fitted in the capsul 44 afterwards, O type circle 40 is enclosed within on the axle 17, seal ring 45 after installing, big seal ring 42, capsul 44 usefulness screws and caterpillar wheel 18 tighten up, the Zhi Kouchu of capsul 44 withstands on the outer shroud of bearing 43 simultaneously, at last seal receptacle 47, the little flexible rubber ring 41 that installs is fitted on the axle 17.

The utility model is compared with prior art, have simple in structure, long service life, cost is low, and is easy to maintenance, mechanical work efficient height is strong to soil condition comformability, but self desliming, anti-skidding anti-characteristics such as fall into.
