Abstract

The utility model relates to a snow blade which is arranged on a snow and ice clearing machine. In order to prevent that the blade of a snow blade interferes with the road surface when in working, a plurality of blades are arranged in parallel on the tool rest of the snow blade of the utility model. A spring retractor device is arranged between each blade and the tool rest. When in working, each blade can be suitable for the shape of the road surface, and contact the road surface with appropriately same pressure, which realizes that the compacted snow and ice can be peeled off cleanly comparatively and the road surface can not be damaged.

Description

Snow removing shovel

The utility model relates to a kind of being installed in and removes ice and snow snow removing shovel mechanically.

In northerly winter, the removing of snow way of escape area snow is the work of a difficulty.The snow removing shovel of rigidity on the existing machinery can produce interference with the road surface when pressing down, and perching knife is difficult to adapt to the shape on road surface with the local contact in road surface.Even the floating snow of shoveling bulky also pushes away untotally, it is a lot of to leave over residual snow.To tread through the pedestrian or traffic-compacted accumulated snow powerless especially.Therefore, the accumulated snow that a large amount of manpowers are rooted out pavement compaction will be set out after avenging in northern city.

The purpose of this utility model provides a kind of snow removing shovel, and it can strip down the accumulated snow of compacting on the road surface under the drive of machinery, improves the speed and the quality of road surface snow removing in winter.

In order to achieve the above object, the utility model has adopted the elasticity snow removing shovel, is equipped with manyly perching knife on the knife rest side by side, and perching knife is with the telescopic spring device is housed between the knife rest.

The utility model has been because adopted the elasticity snow removing shovel, is equipped with manyly perching knife on the knife rest side by side, rather than one whole perching knife, and every perching knife with the telescopic spring device is housed between the knife rest, perching knife with between the knife rest, perching knife is with stretching mutually between the perching knife.During snow removing shovel work, each perching knife can adapt to the shape on road surface, with roughly the same pressure contact road surface, can not produce with the road surface and interfere.So can push away totally floating snow during snow pushing, the ice and snow of compacting can be peeled off relatively totallyer when shoveling ice and snow or cutting ice and snow, and not damage the road surface.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 to Fig. 4 is respectively the structure chart of the several embodiment of the utility model.

As shown in Figure 1, snow removing shovel is made of parts such as knife rest 1, several perching knives 2, guide post 3, helical spring 4, bolt 5, nuts 6.Perching knife 2 usefulness bolts 5 are fixed on the guide post 3.Guide post 3 passes the pilot hole of knife rest 1, is matched in clearance with pilot hole.Helical spring 4 is enclosed within the position between knife rest 1, perching knife 2 on the guide post 3.Nut 6 is screwed on the screw thread of guide post 3 tail ends, screws in or screw out the pretightning force that nut 6 can be adjusted helical spring 4.Snow removing shovel shoveling or when cutting ice and snow, machinery can be adjusted to following state: the knife rest 1 that is installed in mechanically drives perching knives 2 motion downwards earlier by guide post 3, behind the perching knife incision ice and snow, the perching knife that touches the road surface is the compression spring earlier, stops to move downward; All the other perching knives continue downwards, till all contacting the road surface.When all springs all by compression, when all perching knives all contacted the road surface, knife rest drove perching knife and forwards moves, and peels off ice and snow.Because all perching knives are all with road surface contact, and road pavement has certain, roughly the same pressure, and the ice and snow when perching knife advances on the road surface can be peeled off relatively totallyer.In fact, perching knife downwards, two kinds of motions forward can combine simultaneously and carry out, and it is exactly like this that snow removing shovel is installed on the snow removing machinery of rotation.

Fig. 2 is the front view of another embodiment of the present utility model.Fig. 3 is the vertical view of this embodiment.In Fig. 2, Fig. 3, a plurality of perching knives 8 have been installed on the knife rest 7.The guide plate 8A on perching knife 8 tops is contained among the gathering sill 7A of knife rest 7, and perching knife 8 can only slide up and down along gathering sill 7A.Helical spring 9 upper ends are supported on the knife rest spring base 10, and the lower end is supported on the perching knife spring base 11.When perching knife 8 is installed,, when locating hole on the knife rest 7 is exposed in guide plate 8A below, load onto bolt 12 on knife rest 7, can prevent that just perching knife 8 from coming off by perching knife spring base 11 compression helical springs 9.Install after the perching knife, helical spring 9 promptly has preload pressure.The same example of the course of work of present embodiment is not given unnecessary details in addition.

Embodiment shown in Figure 4 is roughly the same on structural principle with embodiment shown in Figure 1, and 2 differences are only arranged.One of difference is: helical spring 13 is not to be enclosed within on the guide post, but its upper end is placed on holding in the hole of knife rest 14, and the lower end is supported on the perching knife spring base 15.Two of difference is: the adjacent regions of perching knife arranged side by side, and one the fluted B of perching knife, and another perching knife has protruding C, and the height dimension of groove B is greater than the height dimension of protruding C.Projection C stretches among the groove B, and engaged, adjacent perching knife both can independently move up and down within the specific limits, but the interlock that checks and balance, unlikely in height staggering too much.The purpose of this structure is to prevent that indivedual perching knives from inserting not bad perching knife of steep hole.
