MODE FOR INVENTION

(8) The present disclosure is now described in detail in connection with the drawings.

(9) As shown in FIG. 1, the disclosed land leveler used for a side snowplow may include a rear mounted seat 1, a hydraulic cylinder I 3, a pull rod 4, a snow-pushing board 7, an oscillating rod 10, a hydraulic cylinder II 11, and a front mounted seat 12. The rear mounted seat 1 may be fixed at the rear portion of a rear rack of the land leveler. The rear mounted seat 1 may be hingedly connected to a hinge plate I 2 through a pin 9. On end of the pull rod 4 may be hingedly connected to the hinge plate I 2 through pins, and the other end of the pull rod 4 may be hingedly connected to a hinge plate II 6 through fixed pins 5. One end of the hydraulic cylinder I 3 may be hingedly connected to the rear mounted seat 1, and the other end of the hydraulic cylinder I 3 may be hingedly connected to the pull rod 4. The front mounted seat 12 may be fixed at the front portion of the rear rack of the land leveler. One end of the oscillating rod 10 may be hingedly connected to the front mounted seat 12, and the other end of the oscillating rod 10 may be hingedly connected to the hinge plate III 8 through pins 9. One end of the hydraulic cylinder II 11 may be hingedly connected to the front mounted seat 12, and the other end of the hydraulic cylinder II 11 may be hingedly connected to oscillating rod 10. The snow-pushing board 7 may be positioned on the left side or the right side of the land leveler. The snow-pushing board may incline to the direction the land leveler is moving forward. The rear portion of the snow-pushing board 7 may be connected to the hinge plate II 6, and the front portion of the snow-pushing board 7 may be connected to the hinge plate III 8.

(10) As shown in FIG. 2, the hinge plate III 8, the hinge pin 9, the oscillating rod 10, the hydraulic cylinder II 11, and the front mounted seat 12 may from a lifting mechanism provided by the present disclosure. A small moving distance of the cylinder may result in a relatively high lifting of the snow-pushing board. The blade may effectively avoid a barrier object.

(11) Further, as shown in FIG. 4, the pull rod 4 may include a steel tube 13, a copper sleeve 14, blocking plates 15, a blocking pedestal 17, and a sliding rod 19. One end of the copper sleeve 14 may include a protruded shoulder. The protruded shoulder may be used to mount two semicircular blocking plates 15. The semicircular blocking plates 15 may fix the copper sleeve 14 at an end portion of the steel tube 13 through bolts 16. The sliding rod 19 may pass through the copper sleeve 14 and slide in the steel tube 13. One end of the sliding rod 19 may include a blocking pedestal 17. The blocking pedestal 17 at one end of the sliding rod 19 may prevent the sliding rod 19 from sliding out of the copper sleeve 14.

(12) Further, the sliding rod 19 may include a spring 18. The spring 18 may be compressed between the steel tube 13 and the sliding rod 19. When the snow-pushing board 7 scratches a protruded stiff object on the road surface, the sliding rod 19 may slide in the steel tube 13, and the spring 18 may be compressed. The spring 18 may buffer the scratching between the snow-pushing board 7 and the road surface.

(13) As shown in FIGS. 5 and 6, further, pins may be soldered on the hinge plate III 8. The snow-pushing board 7 may be hingedly connected to the hinge plate III 8 through the bushing 20 and a fixing base 21. The snow-pushing board 7 may rotate up and down about the pins on the hinge plate III 8 to adjust the angle of the snow-pushing board 7. Thus, the snow-pushing board 7 may be moved up as shown in FIG. 3 or moved down as shown in FIG. 1.

(14) Further, the hinge plate II 6 may be configured with two fixed pins 5 to prevent the snow-pushing board 7 from swaying.

(15) The operation of the side snowplow may be described as follows: as shown in FIGS. 1 and 3, when the land leveler is moving forward, the hydraulic cylinder I 3 may extend and the hydraulic cylinder II 11 may retract. The pull rod 4 and the oscillating rod 10 may be raised up to lift the snow-pushing board 7 off the ground and avoid barrier objects. When in operation, the hydraulic cylinder I 3 may retract and the hydraulic cylinder II 11 may extend. The pull rod 4 and the oscillating rod 10 may move towards the ground such that the snow-pushing board 7 may land on the ground and perform snow plowing.
