Description

A kind of agricultural machinery chassis

Technical field

The utility model relates to a kind of agricultural machinery chassis, mainly is the agricultural machinery chassis that is used to install underwater cultivation, harvesting machinery.

Background technology

The normally wheeled and crawler type in present agricultural machinery chassis relatively be suitable for dry area, the north and use, but in area, southern paddy field, the rubber-tyred chassis can not be used substantially because tire sink, and also there is difficulty in walking in caterpillar chassis, the problem that energy consumption increases.

The utility model content

The purpose of this utility model provides a kind of agricultural machinery chassis of using in the paddy field that is applicable to, to solve the deficiencies in the prior art.

The purpose of this utility model is achieved in that a kind of agricultural machinery chassis, comprise sole, internal combustion engine and gearbox are installed on the sole, internal combustion engine and gearbox are in transmission connection, the gearbox two ends are connected with two driving wheels, gearbox can carry out differential control to two driving wheels, the sole rear portion is equipped with handrail, lower end, sole the place ahead is equipped with two front axles on same axis, two front axle outsides all are equipped with driven pulley, each driven pulley is connected by chain drive with the driving wheel of homonymy, connect by lining in the middle of two front axles, make two front axles keep same axis, lower end, sole rear is equipped with rear axle, it is characterized in that: rubber tire and concavo-convex wheel the before all being equipped with on the every front axle, preceding rubber tire is narrow body design, slightly larger in diameter is taken turns in concavo-convex, be installed on the concavo-convex outside of taking turns, the concavo-convex wheel is expanded letter, and inside is cavity structure, the concaveconvex structure of concavo-convex wheel outer surface is a smooth curved surface, the back rubber tire is installed in the middle of the rear axle, and back rubber tire both sides are equipped with two floating drum wheels, and the floating drum wheel is the cylindrical cavity structure, back rubber tire is narrow body design, and slightly larger in diameter is taken turns in floating drum.

As preferably, a plurality of concavo-convex wheel of same size is installed on every front axle, a plurality of concavo-convex double wedges of taking turns are staggered to be arranged, and makes double wedge approach circle on axis projection.

As preferably, be fixed with raised line on concavo-convex each double wedge of taking turns.

As preferably, the outer rim in two floating drums wheel outsides has corner cut, makes the floating drum wheel outside be frustum cone structure.

As preferably, handrail comprises handrail cover and bar, and bar inserts in the handrail cover, connects by pin-and-hole, and a plurality of locating holes are arranged on the bar, can regulate the length of handrail.

During use, starting apparatus combustion engine, the internal combustion engine drive gearbox, gearbox drives two driving wheels and rotates, driving wheel drives driven pulley by chain, two front axles are rotated, be installed in front axle concavo-convex are taken turns and rubber wheel rotates simultaneously, when the agricultural machinery chassis on the road surface or during hard ground run, because preceding rubber tire slightly larger in diameter is taken turns in concavo-convex, back rubber tire slightly larger in diameter is taken turns in floating drum, concavo-convexly takes turns, the floating drum wheel contact with ground, is travelled by forward and backward rubber tire carrying and driving agricultural machinery chassis; When travel in the paddy field in the agricultural machinery chassis, forward and backward rubber tire sink, concavo-convexly take turns, the floating drum wheel contacts with muddy water, the weight that concavo-convex buoyancy of taking turns the cavity structure generation of taking turns with floating drum carries the supporting agricultural machinery of installing on agricultural machinery chassis and the chassis, the concavo-convex wheel stirred muddy water when rotating, advanced in the agricultural machinery chassis, the smooth curved surface of concaveconvex structure can prevent that earth is in the concavo-convex depression position adhesion alluvial of taking turns, when need turn left in the agricultural machinery chassis, control gearbox left side output speed reduces, make front axle left side concavo-convexly take turns, the rubber wheel rotating speed is lower than the right side, turned left in the agricultural machinery chassis; Otherwise when need turn right in the agricultural machinery chassis.When the agricultural machinery chassis turned to, the floating drum at rear portion wheel had sideslip to a certain degree, the resistance the when frustum cone structure in the floating drum wheel outside can reduce the floating drum wheel and breaks away in mud.Concavo-convex raised line of taking turns on the double wedge can prevent that agricultural machinery chassis concavo-convex wheel when crossing the raised path through fields from skidding.The handrail of adjustable length is applicable to the agricultural machinery chassis multiple agricultural machinery is installed, and can be reduced in size when deposit on the agricultural machinery chassis, is convenient to deposit.A plurality of concavo-convex stacks of taking turns are used single concavo-convex double wedge quantity of taking turns is reduced, and increase the spacing of double wedge, further avoid earth in the concavo-convex depression position adhesion alluvial of taking turns, and keep the double wedge sum simultaneously, help the smooth-ride on agricultural machinery chassis.

By implementing the utility model, changed the walking manner of original technology, solved the problem of existing agricultural machinery inconvenient walking in the paddy field, simultaneously, telescopic handrail can make the utility model be applicable to the agricultural machinery that different size is installed.

The utility model is further described by embodiment below in conjunction with accompanying drawing.
