Description

The three-wheel tillage machine that a kind of wheel is identical

The utility model relates to the identical three-wheel tillage machine of a kind of wheel, belongs to agriculture scarification equipment class, is specially adapted to the farming in paddy field.

Existing underwater cultivation machinery has multiple, has to plough a field, and harrows a field, the floating ship etc. that rolls, all be to drive machine-walking, drag plough or rake, plough a field earlier and stir field mud, harrow a field again by power, harrow a field through repeated multiple times and just can rake, and mostly machinery is heavy, complexity uses not as people's will.

The purpose of this utility model is to provide a kind of plough that neither needs, and does not also need rake, and simple in structure, parts are few, only need three wheels down on the farm, and the intersection walking is one time anyhow, just can finish the tillage machine of plough, rake operation.

The three-wheel tillage machine that this wheel is identical, its design is to adopt existing fraction horsepower diesel engine to drive two front-wheel rotations by two output shafts about reductor, drag a trailing wheel on the connecting rod that is fixed on the reductor, these three wheel shapes are identical, be that uniform iron plate tooth is formed on wheel, its iron plate tooth is under the weight of the vehicle body and the driving person, be pressed into field mud, stir field mud during walking, intersection is stirred, cut broken, rake, play and plough a field, the effect that harrows a field is connected with pilot instrument on reductor, utilize a left side, the commentaries on classics of off-front wheel with not then turn round, turning radius is little, and it is few to plough whole dead angle.

The three-wheel tillage machine that this wheel is identical, comprise diesel engine 1., reductor 3, front-wheel 4, trailing wheel 10, connecting rod 6, pilot instrument, it is characterized in that described reductor 3 and pilot instrument, connecting rod 6 and diesel oil frame 2 usefulness screws fixed be one, left and right two output shafts 23 of the concentric of reductor directly cooperate affixed with two front-wheels respectively, reductor gear lever 11 stretches to the driving handle orientations, conveniently is as the criterion with hand operated.

Described connecting rod 6 is fixed on the reductor rear wall, trailing wheel 10 is installed on the support 12 that is fixed on the connecting rod 6, be provided with the device of regulating the whole field depth between trailing wheel 10 and the front-wheel 4, described adjusting device, comprise depression bar 8 and adjusting rod 9, depression bar 8 is curve bends, flexibly connect with connecting rod 6, circular arc and the field face is tangent drags, the trailing wheel direction, on depression bar 8, be connected with an adjusting rod 9, uniform aperture is arranged on the adjusting rod 9, utilize Xiao Ding or bolt to be connected the height of regulating depression bar 8 with connecting rod 6.

Described diesel oil frame 2 is fixed on the antetheca of reductor 3, and mounting diesel engine 1 on it.

Described pilot instrument, comprise two bars 5, drive handle 16, clutch handle 13, two turning joysticks 17, driver's seat 19, its special feature is the left side that two bars 5 are fixed in reductor 3, on the wall on right both sides, be provided with tool box 7 between two bars, driver's seat 19 is fixed on the seat connecting rod 18, seat connecting rod 18 is movably connected in the tail end of connecting rod 6, be connected with a limiting plate 15 on the connecting rod 6, and be provided with seat adjuster, described seat adjuster is that the tail end at connecting rod 6 is connected with a claw plate 14 and limiting plate 15, being provided with the ratchet lever of being controlled by spring 26 25 with the claw plate corresponding orientation on seat connecting rod 18 presses in the ratchet of claw plate, make driver's seat can regulate height, in time spent not, but the rotation direction relative direction, and saving takes up room.Remainder is same as the prior art, is provided with clutch handle 13 as driving the connecting plate 24 that is provided with on turning joystick 17, the bar 5 below the handle 16.

Described two front-wheels 4 are identical with a trailing wheel 10 these three wheel shape, be on cylinder, to form with the uniform in the same way iron plate cutter of wheel shaft, its special feature is that wheel wheel footpath is little, the wheel fabric width, the iron plate height, 200～300 millimeters of cylinder diameters, 300～500 millimeters of spokes, iron plate is cut a hole high 150 millimeter, iron plate cutter footpath sheet is provided with a plurality of square or circular holes, the hole, so that weight reduction, also can broken field mud, three wheels in front and back can be identical, also can two front-wheels identical, the trailing wheel shape is identical, and the wheel footpath can be less than front-wheel, and spoke should be slightly larger than the distance between two front-wheels.

According to the tillage machine of above conceptual design, through facts have proved, its advantage is: reasonable in design, simple in structure, member is few, and is in light weight, fault is few, easy-maintaining, long service life need not be ploughed, rake, only need horizontal down on the farm, orthogonal fork walking one time can be finished plough, labour and power are saved in the whole operations that harrow a field, radius of turn is little, whole dead angle, field is few, and the whole field depth can be regulated, and can walk in 0.5 meter wide road, only need the dark water of 1 cun can put in order the field, fertilizer does not run off, and looks fast after the seedlings of cereal crops insert, and is applicable to the mountain area, hills and Plain different shape, greatly, little paddy-field-working.

Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.

Accompanying drawing 1 is a side structure schematic diagram of the present utility model;

Accompanying drawing 2 is a planar structure schematic diagram of the present utility model.

The each several part title is as follows among the figure:

The 1-diesel engine, 2-diesel oil frame, 3-alkali speed machine, 1,4-front-wheel, the 5-bar, 6-connecting rod, 7-T tool case, 8-depression bar, 9-adjusting rod, the 10-trailing wheel, 11-gear lever, 12-rear wheel support, 13-clutch handle, the 14-claw plate, the 15-spacing hole, 16-drives handle, 17-turning joystick, 18-seat connecting rod, 19-driver's seat, 20, the 22-belt pulley, 21-belt, the 23-output shaft, 24-connecting plate, 25-ratchet lever, 26-spring.

This tillage machine course of work is as follows: start diesel engine, by belt pulley 20,22 belts 21, make the tillage machine walking, the driver is sitting on the driver's seat, ride on rear wheel support, tillage machine is left for the operation paddy field, at first at keep to the side horizontal stroke or of Tanaka directly to walking, behind opposite side, spur the turning joystick, make on one side front-wheel not then turn round 180 °, then near the first time track route the limit oppositely walk, behind opposite side, spur the turning joystick of another side again, turn round 180 °, near the limit backward going of the track route second time, walking successively, after covering to whole field face, turn round 90 ° again, cover whole fields face successively, promptly finish full field tillage work, mud smooth exquisiteness in field gets final product rice transplanting.The depth in whole field can be adjusted by adjuster, and depression bar is turned down, and then trailing wheel rises, and by back gravity, front-wheel also can rise relatively, level before and after reaching, plough so whole depth as shallow some, otherwise, then deeply.When transfer tasks, as long as there is 0.5 meter wide path to walk, as ditch, water channel, only need two wood, pad is laid down or removed trailing wheel and can pass through under front-wheel, and is simple, convenient, lightly, one meter wide machine, weight can be provided with dashboard on trailing wheel about 400 kilograms, belt pulley is established safety guard, and handling safety is reliable.
