Abstract

The utility model relates to a balance supporting wheel for a tractor plough, which relates to a special balance supporting component of a tractor plough. The support of surface contact or line contact of the original tractor plough is changed to the support of point contact, and namely, a wheel type supporting wheel with teeth which are made of steel plates is designed. While the utility model is used, the supporting wheel follows the tractor plough to move forwards and synchronously rolls on ridges; the straight-line driving supporting wheel of the utility model performs straight-line rolling on the ridges. When the utility model turns, soils generate certain side pressure to the supporting wheel, a vertical rod on a wheel carrier is caused to rotate, and the supporting wheel swings right and left, so the purpose of self positioning is realized. Proved by operation in a paddy field, the utility model has the advantage of flexible turning; the ridges can not be frayed, and the utility model has the function of earth break.

Description

Balance support wheel of tractor plough

The utility model relates to a kind of special-purpose balanced support parts of maneuver plough.

Now, the balanced support parts overwhelming majority of maneuver plough is a disc type, wide 500 millimeter of trying to get to the heart of a matter, random groups is advanced during operation, with ploughing the upturned soil base that turns over is that face contacts, the upturned soil base that it will overturn to be repeating one times area plain grinding, and the upturned soil base that promptly turns will polish through twice, and this does not meet agriculture requirement; The rod-type balanced support is also arranged, it as number of patent application 88212247.9 maneuver plough bascule, it has adopted a kind of rod-type balance sled as the balanced support parts, advance at random, with the upturned soil base of having ploughed is that line contacts, though overcome the disadvantage of face contact, but still for the bar strip with certain-length slides, turning resistance is big in the upturned soil base.

Technical solution of the present utility model is the support design one-tenth point contact supporting with face contact or line contact, promptly be designed to have the wheeled bogie wheel of tooth, it partly is made up of bogie wheel (7), wheel carrier (4), montant (1), inclination-angle regulating device (6) four, as shown in Figure 1, bogie wheel (7) is connected (see figure 2) by fanning strip (6) one ends with wheel shaft (8); The fanning strip other end is connected with wheel carrier (4) by screw rod (9), forms a support unit.Open the arc groove of a parallel circular arc on the fanning strip, so that regulate support height.Design has the gear teeth on the wheel rim, and its gear teeth are made into by steel plate.Wheel can not skid, can play the hack effect when rolling like this.During application, shown in Fig. 2, montant on the wheel carrier (1) is inserted in the terminal circular hole of balancing pole (3) (10) on the maneuver plough from bottom to top, is to adapt to paddy field mud pin depth support height, diverse location and the wheel carrier gradient that can regulate pin-and-hole on the montant (2).Dark as the mud pin, the hold-down nut (9) on fanning strip both sides is unclamped, clockwise rotate wheel carrier (4) when shallow (then round about rotate as the mud pin), till ideal height, fastening nut can drop into operation again.Bogie wheel with maneuver plough before so that synchronous rolling; The unit straight-line travelling, bogie wheel is made straight-line rolling on the upturned soil base, and during turning, soil is given the certain lateral pressure of bogie wheel, and montant (1) is rotated, and causes wheel to swing, and reaches the purpose of self-alignment.Tooth on the wheel rim also can play the hack effect.

For adapting to the paddy field mud pin depth, regulate support height, on montant, be provided with 5～9 pin-and-holes (2).

This maneuver plough balanced support wheel proves by paddy-field-working, turns flexibly, does not grind base and the effect of hack is arranged.

Description of drawings:

The main schematic diagram of looking of Fig. 1 balanced support wheel.

Fig. 2 balanced support wheel schematic top plan view.

Embodiment:

Accompanying drawing is described to be an embodiment of this case.By using with ploughing and leveling machine for paddy field is equipped with south one 5 type disc types are many, plough a field in interior paddy field for dark 250 millimeters at the mud pin, balanced support is imitated and is adopted, and turns flexibly, has overcome existing maneuver plough with the mill base disastrous effect that the balancing frame supporting brings, and meets agriculture requirement fully.

Claims
