Abstract
The utility model discloses a tractor wheel gage adjusting device which comprises a horizontal hydraulic cylinder, wherein the two ends of the hydraulic cylinder are respectively hinged to a shaft body fixing part and a square hollow wheel arm; the shaft body fixing part above the hydraulic cylinder is horizontally and fixedly connected with a square inner beam having a cross section of an outer-square, inner-circular structure; a spline shaft is arranged in the square inner beam; the square hollow wheel arm with a fastening bolt and the square inner beam are in sliding fit and are sleeved together; a spline shaft sleeve is arranged in the square hollow wheel arm; the spline shaft sleeve and the spline shaft are in sliding fit and are sleeved together. Due to the adoption of the adjusting device, the wheel gage can be adjusted without suspending the tires of the tractor, so as to save labor and time and reduce labor intensity.
Description
Technical field
The utility model relates to a kind of trac. Wheel space adjusting device.
Background technology
Trac. wheelspan regulation technology is main still by artificial at present, need to tractor wheels is unsettled, one by one tractor wheels is regulated manually.Very inconvenient like this, adjusting time that need to be very long and very large working strength.
Summary of the invention
The utility model provides a kind of trac. Wheel space adjusting device, can carry out adjusting knurl distance by tractor tire is unsettled, and it is time saving and energy saving to use, and labor strength is low.
The purpose of this utility model is achieved in that a kind of trac. Wheel space adjusting device, this control apparatus comprises the hydraulic actuating cylinder of a horizontal arrangement, the two ends of hydraulic actuating cylinder are hinged with axis body fixed part and square hollow wheels arm respectively, on the axis body fixed part of hydraulic actuating cylinder top level affixed a square inner beam, the cross-sectional plane of square inner beam is square-outside and round-inside structure, in square inner beam, castellated shaft is being set; Square hollow wheels arm and square inner beam bearing fit with binding bolt are set in together, and in square hollow wheels arm, hub splines are being set, and hub splines and said castellated shaft bearing fit are set in together.
Adjusting knurl is apart from front, first unclamp binding bolt, square hollow wheels arm can be slided closely on square inner beam, the structure of square inner beam is inner circle foreign side, under the effect of hydraulic actuating cylinder, make afterwards the wheel being connected on square hollow wheels arm move outwardly or inwardly, after being adjusted to the position needing, the action of stop solution depression bar, has completed the wheelspan adjusting work of trac..
In trac. course of normal operation, the rod chamber of hydraulic actuating cylinder and rodless cavity inside are all full of fluid with pressure and keep piston rod in oil cylinder, not to be subjected to displacement, thereby have played the maintenance effect to trac. wheelspan; Binding bolt can fully compress square hollow wheels arm and inner beam and prevent that it from occurring to slide each other and auxiliaryly prevent that in trac. driving process, wheelspan changes.
Trac. adjusting knurl is to complete by the mutual mobile Following effect between castellated shaft and its outside close-fitting hub splines apart from the driving force connecting device in process.
Because the Planting Row Distance of different crops is different, it is adjustable that this just requires farm vehicle can realize wheelspan when farm work, and vehicle, through the bad section of road conditions, need to guarantee normally to travel by adjusting knurl distance equally.The utility model has been realized the wheelspan regulating action of wheel semi-automation, can carry out adjusting knurl distance by tractor tire is unsettled, and it is time saving and energy saving to use, and labor strength is low, and use procedure is convenient, flexible adjustment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
The specific embodiment
A kind of trac. Wheel space adjusting device, as shown in Figure 1, this control apparatus comprises the hydraulic actuating cylinder 1 of a horizontal arrangement, the two ends of hydraulic actuating cylinder 1 are hinged with axis body fixed part 8 and square hollow wheels arm 6 respectively, on the axis body fixed part of hydraulic actuating cylinder 1 top level affixed the square inner beam 2 of a hollow, the cross-sectional plane of square inner beam 2 is square-outside and round-inside structure, the interior castellated shaft 4 that arranging of square inner beam 2; Square hollow wheels arm 6 with binding bolt 3 and plain cushion 7 is set in together with square inner beam 2 bearing fits, the interior hub splines 5 that arranging of square hollow wheels arm 6, and hub splines 5 is set in together with said castellated shaft 4 bearing fits.
