Abstract
The utility model relates to a small dual-purpose tractor used for farmland operation and short-distance transport. A small size wheel tractor and a carriage are connected into integration by a crossbeam, a transmission shaft (4) on a clutch transmission case (10) is prolonged, a rear axle (12) matched with the transmission shaft is moved to the lower part of the carriage (7) as a drive wheel axle, and a traction frame (6) on a head section is moved to the tail end of the crossbeam (1) for towing agricultural implements. When the utility model is used for short-distance transport, 3/5 of the weight of the whole tractor presses on rear driving wheels so as to prevent the tractor from slipping on a smooth road surface. When the utility model is climbing, the head section is in harmony with the carriage, and safety factor and climbing capacity are enhanced.
Description
The utility model is used for the double moving defeated small-sized dual-purpose dilatory car of short distance of doing of farmland operation, comprises combustion engine operator's compartment and railway carriage on the head.
The minitype wheeled tractor that is used for farmland operation now hangs up trailer and can be used for short-distance transport.After minitype wheeled tractor hangs up trailer, only be adapted at normal road traveling, because head separates with trailer, do not form an integral body, when travelling on acclive road surface, inharmonious phenomenon can appear in the cooperation of head and trailer, the drawbar frame of trunk upwards levers up during climbing, moves after the center of gravity, and drawbar frame produces application force upwards to the head drive wheel, reduced the tractive force of trac., drive wheel idle running can not continue climbing when serious, causes behind the car body sliding, engine off, its consequence is hardly imaginable.When road conditions are bad, because head and trailer are hinged with pin by drawbar frame, bump many times takes place in the process of moving, destroyed the smooth operation of combustion engine on the head, shortened used life.The minitype wheeled tractor breakdown trailer, safety factor is little, and head does not have shock attenuation unit, and combustion engine is had infringement, and in addition, combustion engine driving wheel and power-transfer clutch flower wheel distance is far away on the head, and drive belt reaches two meters, and the power that is hampered is easily skidded.
The purpose of this utility model is to avoid the deficiency of above-mentioned present technology existence, and provides a kind of head and trailer to form the small-sized dual-purpose dilatory car of single-piece.
The purpose of this utility model can reach by the following technical programs: in conjunction with the structure under truck headstock and the railway carriage, prolong the transmission shaft of minitype wheeled tractor, back axle moves on to do below the trailer and drives oil, head and trailer are linked to be integral body with crossbeam, drawbar frame moves on big tail beam on the head, make head and trailer become an integral body after transforming like this, can the front and back close look at the swing when travelling.
Above-mentioned crossbeam forms trapezoidal shape upwards above back axle, this crossbeam is equipped with the spring plate bow that upwards arches upward between back axle, and this bow is made up of multilayer bow plate, and the longest bow plate is positioned on the top, below being positioned on of vice-minister, and the shortest bottom that is positioned on.These bow two ends and crossbeam are hinged.The driving wheel front of combustion engine is towards operator's compartment, and and the flower wheel of power-transfer clutch between centre distance be 0.6 meter.Enforcement by such scheme can make separation system minitype wheeled tractor and trailer form an integral body, can realize this purpose.
The utility model is compared with above-mentioned present technology can have following effect: because small-sized wheeled trac. is connected as a single entity with crossbeam with the trailer that separates, form small-sized dual-purpose dilatory car, promptly can be used for farmland operation, can doublely do short-distance transport again.Especially do transport trolley, make car load
Weight all be pressed in the rear drive, travelling on the ice face can prevent to skid, and has improved the land locomotion ability.During climbing, head is consistent with the action thing accent of railway carriage, improves hill climbing ability and safety factor.Can reduce mutual bump in the process of moving, prolong the used life of equipment, the generation of minimizing accident.In addition, the flower wheel of driving wheel and power-transfer clutch has improved Belt Transmission Efficiency apart from shortening on the combustion engine, has increased functional reliability.The vibration that front and back spring guiding principle plate bow can alleviate car load makes the combustion engine smooth operation, has also raised crossbeam simultaneously, does not injure young crops during farmland operation.Upwards arch upward in the middle of back axle (12) the upper spring steel plate bow, fill the elasticity that pilosity is waved bow, be suitable for the bigger tractor driving wheel of diameter and use.
Accompanying drawing 1 is the utility model diagrammatic sketch;
Fig. 2 is the assembly drawing of change speed gear box on Fig. 1 (10) transmission shaft (4) back axle (12).
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing 1, the reason that fuses by crossbeam according to the headstock and the railway carriage of truck, the transmission shaft (4) of small-sized wheeled gear box of tractor (10) is prolonged, below back axle (12) that transmission shaft assembles mutually moves on to railway carriage (7), do axle drive shaft (bridge), promptly combustion engine (3) operator's compartment (5) and railway carriage (7) all are installed on the whole crossbeam (1).Make trac. and trailer form an integral body: the drawbar frame on the head (6) moves on on the tail end of crossbeam (1), pull agricultural machinery and implement, transmission shaft (4) is installed between change speed gear box (10) and back axle, the power of diesel engine (3) is through the master, flower wheel (8,9), change speed gear box (10) and transmission shaft (4) pass to the back axle (12) below the railway carriage, constitutes small-sized dual-purpose dilatory car.Crossbeam (1) trapezoidal shape that formation makes progress above back axle (12) wherein.Between crossbeam (1) and propons (13) back axle (12) spring plate bow (11), (2) are housed, the shape of the spring plate bow (2) of back axle (12) for upwards arching upward, the two ends and the crossbeam of bow are hinged.The front of the driving wheel (8) of combustion engine (3) is towards operator's compartment, and and the flower wheel (9) of change speed gear box (10) between centre distance be about 0.6 meter, shortened 0.5 meter of strap length, improved Belt Transmission Efficiency, given full play to the effective power of diesel engine.
Claims (4)
1, a kind of farmland operation and double small-sized dual-purpose dilatory car of doing transportation of being used for, have head (3) (5) and railway carriage (7), it is characterized in that prolonging the transmission shaft (4) of change speed gear box (10), move on under the railway carriage (7) with back axle (12) that change speed gear box (10) assembles mutually and to do driving rear axle, combustion engine (3) operator's compartment (5) and the shared one crossbeam of railway carriage (7), the drawbar frame (6) of back axle (12) moves on the tail end of crossbeam (1).
