Abstract
The utility model relates to a multifunctional farm machine with a suspension crankshaft type track, which is composed of a power transmission mechanism, a control mechanism, a track-mounted track walking mechanism and an operation mechanism; a suspension crankshaft mechanism comprises a support bracket, an upper arm shaft, a suspension arm, a lower suspension shaft, left and right upper arm shaft sleeves, a tensioning screw rod, a regulation nut, a pressure spring and a guide sleeve hole; the upper arm shaft of a suspension crankshaft is articulated in the left and right arm shaft sleeves of the support bracket; a guide driven chain wheel is connected to the lower suspension shaft of the suspension arm; the pressure spring is sheathed and connected on the tensioning screw rod; the front end of the tensioning screw rod is sheathed and connected in the guide sleeve hole of the support bracket, and the rear end of the tensioning screw rod is articulated at the lower end of the suspension arm. When mud, weeds and the like enter a track-mounted track to extrude the guide driven chain wheel, the lower suspension shaft and the guide driven chain wheel are pushed to tension the track so as to keep the guide driven chain wheel and a driving chain wheel carrying out linear motion under any circumferences; the guide driven chain wheel can only swing front and back so as not to derail or push against a gear; therefore, the problems that a driving semi-axle is bent or even a gear box casing is broken can be solved.
Description
Technical field
The utility model relates to a kind of field machine, especially a kind of can cultivation and banking, rotary tillage weeding, harrow a field, the cantilever crank formula crawler belt multifunctional agricultural machine of operation such as transportation.
Background technology
Traditional agricultural tillage machine all is with the wheel operation of walking, is prone to during work skid even phenomenon such as overturning, and also function singleness, the high-mobility, multipurpose, wheeled vehicle use of incompatible modern rural households.For solving the deficiency of traditional agricultural tillage machine; The applicant has applied for that to China national Patent Office a kind of denomination of invention is " track-mounted crawler belt multifunction tiller " in 2010; Its number of patent application is 201020242454.7, is prone to the problem of skidding even overturning when having solved work preferably.But because it is with the operation of chain rail crawler travel, the passive sprocket shaft that leads is a d-axis, in the time of in mud soil, weeds etc. get into chain rail crawler belt; Occur apical tooth easily and walk rail; Gently then jack shaft is crooked, and tiller can not be worked, and seriously then causes consequences such as gearbox body breaks, tiller damage.
Summary of the invention
The technical matters that the utility model will solve provides a kind of cantilever crank formula crawler belt multifunctional agricultural machine, and this machine can not only solve guiding preferably and walked rail and apical tooth by movable sprocket, and need not pull down crawler belt when on the way walking and can install road wheel.
The utility model solves the technical scheme that its technical matters adopted: this cantilever crank formula crawler belt multifunctional agricultural machine; Constitute by Power train, steering unit, track-mounted creeper undercarriage and Working mechanism; The track-mounted creeper undercarriage comprises that drive sprocket, jack shaft mechanism, crawler belt, guiding are by movable sprocket, cantilever crank mechanism; Cantilever crank mechanism comprises bracing frame, goes up arm axle, down outstanding axle, about go up arm axle axle sleeve, tensioning screw, setting nut, pressure spring and guiding trepanning; The last arm axle of cantilever is hinged on to be gone up about bracing frame in the arm axle axle sleeve, and guiding is connected on the following outstanding axle of cantilever by movable sprocket, is socketed with pressure spring on the tensioning screw; Its front end sleeve is connected in the guiding trepanning of bracing frame, and its rear end hinge is connected on the lower end of cantilever.When operations such as this agricultural machine cultivation and banking; Mud soil, weeds etc. get in the chain rail crawler belt and push guiding by movable sprocket, promote outstanding down and are come tensioned tracks with guiding by movable sprocket, and guiding is made automatically regulating before and after movable sprocket and the drive sprocket; Guiding can only swing by movable sprocket; Keep it under any circumstance all making the front and back straight-line motion, thereby guarantee that it can not produce away rail and apical tooth, solved the problem that jack shaft is crooked even gearbox body breaks.
Described jack shaft mechanism is the double end flange hub mechanism that inside flange, end flange constitute, and drive sprocket is installed on the inside flange.When this agricultural machine need on the way be walked, on the end flange of double end flange wheel hub, load onto road wheel, can not need pull down crawler belt and just can load onto the wheel walking.
The beneficial effect of the utility model is:
1, simple in structure, easy disassembling is small and exquisite.
2, easy to operate, turn to flexibly, smooth running has solved mud soil and weeds and has rolled in the chain rail crawler belt, causes the problem that jack shaft is crooked even gearbox body breaks easily.
3, because jack shaft mechanism is the double end flange hub mechanism that inside flange, end flange constitute; Drive sprocket is installed on the inside flange; Therefore when this agricultural machine need on the way be walked; On the end flange of double end flange wheel hub, load onto road wheel, can not need pull down crawler belt and just can install the wheel walking.
