Description
Technical field
The utility model belongs to agricultural mechanical field, specifically a kind of small-sized hillside fields tiller that is mainly used in hillside.
Background technology
At present, the agricultural mechanization degree in level land or large stretch of low gradient farmland is than higher, but for the bigger farmland, hillside fields in hillside farmland, the particularly gradient, the area in every field is less, and big-and-middle-sized agricultural machinery can't be in this type of farming operation.Existing two-wheeled hand tractor is suitable for the farming of haggard, but because its axletree is a dead axle, wheelspan is less, the body center of gravity is higher, so overturn easily when the cross running of slope.Chinese patent CN2259342 discloses a kind of hand tractor that can travel on the trail, mountain area, it is to be provided with a liftable deflecting roller in the place ahead of two main wheels, and this tractor still can't be in slope cross running, farming.Owing to above reason, traditional manual mode is still adopted in the agricultural hillside fields farming of China at present.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be at the small-sized hillside fields of agricultural hillside fields cross running and farming tiller.
The technical scheme that addresses the above problem is: the small-sized hillside fields tiller that is provided comprises engine, speed change gear and two road wheels that are located on the frame, and wherein the output shaft of speed change gear links by tape handler and road wheel.Special feature of the present utility model is: be provided with the elevating mechanism of an aforementioned road wheel at least, an end of the lifting movable part of this elevating mechanism and the wheel shaft of road wheel are hinged.Can make the road wheel ascending, descending by elevating mechanism, make body remain on certain level, thereby adapt at the slope cross running.
Above-mentioned elevating mechanism can adopt tooth transmission elevating mechanism, spiral lifting mechanism, but preferably adopts hydraulicefficiency elevation structure.
Above-mentioned elevating mechanism can be only at a road wheel setting, but preferably each road wheel is provided with an elevating mechanism respectively, promptly, road wheel liter during lifting, another road wheel falls, and can reduce the lifting travel of road wheel like this, is beneficial to the miniaturization of tiller.
The utility model can also travel in the slope when keeping existing small-sized level land tiller characteristics, can regulate the height of road wheel easily by elevating mechanism, to adapt to the farming in different gradient farmland, be farmland, China hillside fields, opened up a new road in particular for the mechanization in the bigger farmland of the gradient.

Embodiment
As shown in Figure 1: engine 2, hydraulic system 6 and speed change gear are housed on the frame 1, and the speed change gear of this example is made up of gearbox 3 and deceleration steering mechanism 4.The elevating mechanism of road wheel 5 adopts hydraulicefficiency elevation structure, it is made up of hydraulic system 6 that comprises hydraulic pump, fuel tank, valve and oil cylinder 61, wherein the tail end of oil cylinder 61 is hinged on the frame, and the wheel shaft of the front end of the movable part of elevating mechanism---piston rod 62 and road wheel 5 is hinged.The output shaft of engine 2 passes to power by driving-belt 7,8 oil pump of gearbox 3 and hydraulic system 6 respectively, the output shaft 9 of gearbox 3 is delivered to the power shaft 10 of deceleration steering mechanism 4 again by driving chain, give road wheel 5 through output shaft 11 and driving chain with transmission of power again after the deceleration.11 of the output shafts of the wheel shaft of road wheel 5 and deceleration steering mechanism 4 pass through connecting rod 12 and connect, it constitutes a variable bit triangle with hydraulic cylinder 61, road wheel 5 is positioned at this vertex of a triangle, when the piston rod 62 of hydraulic cylinder stretches, road wheel 5 will swing up and down around output shaft 11, thereby realize the lifting of road wheel.In addition, frame 1 is provided with handrail 13, and frame rear end is provided with facility hanger 14, and front end also is provided with support bar 15.Clear for drawing, omitted among the figure this example hydraulic pressure, speed change, each externally operated switch lever such as turn to.
The oil cylinder of the hydraulicefficiency elevation structure of this example has two, one of each road wheel, and wherein oil cylinder 61 adopts one-way cylinder, such as ram cylinder.When an oil cylinder oil-feed, the oil return under the action of gravity of tiller of another oil cylinder makes two road wheel one rise and one drop, so not only can simplify the structure of hydraulic system, and lifting is steady, is convenient to operation.
The deceleration steering mechanism of this example is as shown in Figure 2: the left and right sides travelling gear 45,46 that it is connected on the output shaft 11 of deceleration steering mechanism 4 by the left and right sides tooth sector 41,42 on the power shaft 10 that is sleeved on deceleration steering mechanism 4 in the spline mode and back-moving spring 43 thereof, at the shift fork between the tooth sector of the left and right sides 44, is respectively formed, wherein left and right sides tooth sector 41,42 respectively with left and right sides travelling gear 45,46 engagement, the output shaft 11 of deceleration steering mechanism 4 by about two semiaxis 11a, 11b form.In order to make structure compact more, the two-semiaxle 11a of this example, the end of 12b are sleeved on together, and can rotate mutually.Shift fork 44 is operated by left and right sides pull bar 47,48, and when shift fork 44 mediated, left and right sides tooth sector 41,42 meshed with left and right sides travelling gear 45,46 respectively, rotated thereby drive two road wheels by two semiaxis; When shift fork 44 moved to right, right turn gear 42 broke away from right travelling gear 46, and right axle shaft 11b does not change, and left half axle 11a rotation, this moment, tiller was turned right.When desire was turned left, shift fork moved to left to get final product.
Fig. 3 has provided second embodiment of the present utility model, and except that the elevating mechanism of road wheel, other structure is identical with first embodiment.The elevating mechanism of road wheel adopts gear drive, it by turbine 22, worm screw 21, be connected in gear 24 on the turbine wheel shaft, form with the tooth bar 23 of these gear 24 engagements, an end of the movable part of elevating mechanism---tooth bar 23 and the wheel shaft 52 of road wheel 5 are hinged.Turbine and worm can drive with manpower, also can otherwise drive.Rotary worm 21, make tooth bar 23 liftings by turbine 22, gear 24, thereby driving road wheel 5 swings up and down around the output semiaxis 11a of deceleration steering mechanism 4, connecting rod 12 plays a part swing arm among the figure, the output semiaxis 11a of deceleration steering mechanism 4 drives sprocket wheel 51 by driving chain, thereby drives road wheel 5.The turbine and worm of this example can also substitute with a pair of bevel gear, and this belongs to protection domain of the present utility model equally.
