Abstract
The utility model provides a single-wheel structure ensuring stable plowing depth and turnover reversing without impact, which is adapted for depth-limiting transposition device of amplitude-modulated inverting alternative plow, comprising support arm, longitudinal spindle, rotation shaft holder, depth adjustment mechanism, rotation shaft, stopping plate, knee arm, depth-limiting wheel, cushion cylinder and angle regulating mechanism. The rotation shaft holder is hinged with the support arm, and the depth regulating mechanism has two upper and lower symmetrical groups. By employing said depth-limiting transposition device, the depth-limiting wheel can be left-right oscillating around the longitudinal spindle by adjusting the angle regulating mechanism when the plow beam angle is altered in association with the change of the plow body scope. When adjusting the plowing depth, it is only need to change the screw mandrel overhanging length of the depth regulating mechanism and then locking the screw mandrel. Position of the depth regulating mechanism can be limited by the limit bar on the rotation shaft holder. When the plow is turnover reversing, the depth-limiting wheel inverts around the rotation shaft and descends against the push-pull resistance of the cushion cylinder, whereby realizing stable reversing without impact.
Description
Affiliated technical field the utility model belongs to agricultural tillage machine tool technical field, relates to a kind of amplitude modulation reversing two-way plow gauge wheel device.
The mounted plough of background technology band gauge wheel is mainly realized the tilling depth adjustment by the relative position of gauge wheel and plough body basal plane.The reversing two-way plow gauge wheel device of current domestic production, the fixed two-wheel structure of employing is arranged, be that plow frame respectively has a wheel up and down, its gauge wheel is fixed on the plow frame by support arm, adjustment leading screw, hold-down support, by leading screw two wheels is moved simultaneously and adjusts tilling depth.The diameter dimension of this structure gauge wheel is restricted, and limit is reliable deeply inadequately and the consumption material is many, and weight is big, cost is high.Have and adopt a wheel, promptly about upset all use same gauge wheel, utilize the gravity upset of wheel commutation own, do not have buffer unit, impulsive force is bigger; Its rotating shaft holder directly is fixed on the plow frame, limits the adjustment that can't swing of dark device, can not guarantee that gauge wheel is consistent with direction of advance all the time when work.At present, along with wheel tractor more than 100 horsepowers is put on market in a large number, the reversing two-way plow that fabric width is adjustable begins popularization and application, more than the gauge wheel device of this structure just can't use on the amplitude modulation reversing two-way plow.In addition, the dark device of this limit has only the back to spacing, and gauge wheel can be swung forward when operation ran into ditch or ridge, caused limitting dark device inoperative, and tilling depth is dark excessively.And external existing reversing two-way plow gauge wheel has single-wheel gravity type, and its rotating shaft holder is hinged on the plow beam more, the also employing hydraulic jack that direction of travel and limit highly have is deeply controlled, but the equal more complicated of structure generally speaking, and manufacturing cost is higher, and weight is also big.
The summary of the invention the purpose of this utility model is to provide a kind of single-wheel structure, can guarantee that tilling depth is stable and the steady nothing of the commutation of overturning is impacted, and is applicable to the dark transposer of limit of amplitude modulation reversing two-way plow.
The dark transposer of the limit of this utility model mainly is made up of support arm, the longitudinal axis, rotating shaft holder, depth adjustment mechanism, rotating shaft, limiting plate, connecting lever, gauge wheel, cushion cylinder, angle adjusting mechanism.Support arm is fixed on the plow beam with bolt, and the rotating shaft holder is hinged by the longitudinal axis and support arm, and angle adjusting mechanism is connected with the rotating shaft holder with support arm respectively, and the rotating shaft holder is swung around the longitudinal axis.Limiting plate is hinged between the inside and outside clamping plate of rotating shaft holder by rotating shaft, and integrally welded with the gauge wheel connecting lever, and gauge wheel can be spun upside down around the shaft, can swing around the longitudinal axis.Depth adjustment mechanism also is hinged between the inside and outside clamping plate of rotating shaft holder, controls the gauge wheel height by its depth adjustment screw mandrel restriction limiting plate activity.And the cushion cylinder stiff end is connected with the rotating shaft holder, and its axle head then is hinged on the limiting plate.
Above-mentioned angle adjusting mechanism comprises angular adjustment pull bar, angular adjustment screw mandrel, locknut and journal stirrup.The angular adjustment pull bar is welded on the rotating shaft holder, and journal stirrup is welded on the support arm.
Above-mentioned depth adjustment mechanism comprises depth adjustment screw mandrel cover, depth adjustment screw mandrel and locking nut.Depth adjustment mechanism has symmetrical two groups up and down, has only the depth adjustment mechanism of top to play the dark effect of limit during work, and the depth adjustment mechanism of below does not limit tilling depth, swings forward but can limit gauge wheel when running into ditch or ridge.
Adopt the above-mentioned dark transposer of this limit,,, can make gauge wheel swing and keep consistent with direction of advance around the longitudinal axis by adjusting the angular adjustment screw mandrel when the working width of plough changes when the plow beam angle is changed.When the tilling depth of ploughing need change, only need to hold up depth adjustment screw mandrel cover, suitably screw-in or back-out depth adjustment screw mandrel length are locked then and are got final product; And the rotating shaft holder is arranged with two spacing thick sticks up and down, but limited depth is regulated the position of screw mandrel cover, protects positive tilling depth and stablizes.When plough overturn commutation, gauge wheel overturn around the shaft, the resistance whereabouts that overcomes the cushion cylinder top and draw, and commutation process is mild, nothing is impacted.
To be gauge wheels change adjustable angle with direction of advance with the working width of plough to the beneficial effects of the utility model, can be consistent with direction of advance all the time, and the tilling depth restriction is stable, and the upset commutation does not steadily have and impacts, and tilling depth adjusts simple and convenient and adjusting range is big.
The utility model is described in further detail below in conjunction with accompanying drawing and example for description of drawings.
