3, described round brush snowplow, comprise frame, the front of frame is fixed with hydraulic suspension linkage, the rear of frame is by the fixing Vierendeel girder in oblique angle, in Vierendeel girder, cleaning rolling brush is installed, the top of frame front is provided with constrained input direction in the transmission case being greater than 90 ° of oblique angles, Cardan shaft is had to be connected between the input of transmission case and the power output shaft of tractor, the output of transmission case has Cardan shaft to be connected with the gearbox in round brush right-hand end frame, the output of gearbox has sprocket wheel, chain is connected with the sprocket wheel of cleaning rolling brush axle head, cleaning rolling brush after-frame is set a roof beam in place and is provided with the universal wheel of adjustable up-down.
4, described oblique angle transmission case, comprise casing, a bevel gear is had to be connected with upper and lower two bearing mounting holes in casing center by the bearing at gear shaft two ends by the gear shaft at bevel gear center in casing, the front end of casing is provided with bearing chamber, conical tooth shaft is had in bearing chamber, umbrella shape indented joint in the cone tooth of conical tooth shaft and casing, what the conical tooth other end was exposed at bearing chamber outside is generation have the spindle nose of equal portions spline to be connected with the power output shaft of locomotive to call input, in the position of casing front input, rearward corner is greater than 90 ° and brushes flat with mine clearing roller that capable position is same to be provided with the equal portions spline axle head that the bearing chamber identical with input and conical tooth shaft be exposed at bearing chamber outside and to call output.
The features and advantages of the present invention:
1, all around the visual field is good for tractor, four-wheel drive has superpower cross-country power, have more standby (other kind vehicle does not have) unique power output shaft, without the need to being equipped with other power in addition, from 30 horsepowers to the available supporting large, medium and small unit that clears the snow between 300 horsepowers.
2, the thick snow stacked up when heavy snow or multicomputer integration of operation, after the snow blade installed through locomotive front pushes through, the round brush operating environment that clears the snow of locomotive rear pto remains a kind of without thick accumulated snow state, and realize snow pushing and cleaning two kinds of operations, unit once completes.
The present invention is applicable to the snow-removing operation of urban street.
