Description

Snow shovel with multiple snow blades {The snowplow having multiple snowblade}

The present invention relates to a snow removal shovel, and more particularly, to a snow removal shovel having multiple snow removal blades.

Generally, when snow accumulates on roads, snowplows are used to remove snow accumulated on road surfaces. The connecting frame is coupled to the front of the snow removing vehicle, and the snow removing shovel is commonly used to the front of the connecting frame. Basically, the snow removal shovel consisting of a snow removal plate and a snow removal blade coupled to the bottom of the snow removal plate functions to push snow accumulated on the road surface to the outside of the road corresponding to the moving direction of the snow removal vehicle.

It may be desirable that the length of the lower spacing arm 151 be longer than the extended length. The user of the snow removal shovel 100 may adjust the distance between the rear snow blade 132 and the road surface 190 by adjusting the expansion and contraction of the cylinder 160.

7 and 8 are side views for explaining the operation of the snow removal shovel according to the distance between the end of the front and rear snow blades and the road surface according to an embodiment of the present invention.

Reference number 330 illustrates a direction in which the snow removal shovel 100 moves as the snow removal vehicle 200 moves forward. Referring to FIG. 7, the distance between the road surface 190 and the rear snow blade 132 is shorter than the distance of the front snow blade 120. In the present embodiment, the cylinder 160 has been extended as much as possible, and the rear snow blade 132 rotated according to the elongation of the cylinder 160 is currently closest to the road surface 190. According to the present embodiment, the front snow blade 120 removes a part of the upper layer of the snow accumulated on the road surface 190, and the snow passing between the front snow blade 120 and the road surface 190 is the rear snow blade 132. ). The front snow blades 120 and the rear snow blades 132 can remove snow easily without removing the burden on either side because the amount of bonsai is automatically treated to remove the accumulated snow. There is an advantage. The configuration as in the present embodiment may be suitable in a case where relatively much snow is accumulated. Alternatively, when snow is frozen on the road surface 190 and snow is piled up again, the front snow blade 120 may be made of rubber, and the rear snow blade 132 may be made of metal to remove ice. .

8, the distance between the road surface 190 and the rear snow blade 132 is the same as or similar to the distance between the road surface 190 and the front snow blade 120. In particular, the end of the front snow blade 120 and the end of the rear snow blade 132 is to maintain a fairly close distance to the road surface 190. Because the distance between the end of the front snow blade 120 and the road surface 190 is very close, most of the accumulated snow is removed from the front snow blade 120, only a small amount of snow passing through the lower portion of the front snow blade 120. The rear snow blade 132 is welcomed. In this case, since the rod of work can be driven by the front snow blade 120, the configuration as in the present embodiment will be suitable when less snow is accumulated.

9 is a side view illustrating a structure in which the rear snow blade supports the front snow blade according to the elongation of the cylinder according to an embodiment of the present invention.

As shown in FIG. 6, when the length of the cylinder 160 is extended 310, the integral connecting member 131 and the rear snow blade 132 are coupled shafts of the connecting member 131 and the lower separation arm 151. The rotating shaft 172 is rotated (320). At this time, if the length of the cylinder 160 continues to extend (160), as shown in Figure 9, the distance between the front snow blade 120 and the rear snow blade 132 is 0, accordingly the front snow blade 120 and the rear snow blade 132 is in contact. In this case, the contact may be in surface contact as shown in FIG. 9, or may be in the form of a line contact point contact which only partially contacts, unlike in FIG. 9. This embodiment of the rear snow blade 132 has a structure that is integral with or support the front snow blade 120 provides a variety of advantages. According to the present embodiment, due to the overlap of the plurality of snow blades there is an advantage that can provide a snow removal shovel having a single high snow blade. In addition, according to the present embodiment, when the material of the front snow blade 120 and the rear snow blade 132 is different, and the rear snow blade 132 is longer (that is, the rear snow blade 132 from the road surface 190). ) When the separation distance from the road surface 190 to the front snow removal blade 120 is closer), and there is an effect such as replacing the snow blade without a separate replacement work. That is, when the front snow blade 120 is a rubber material, and the rear snow blade 132 is a metal, applying the present embodiment has the effect of replacing the snow blade of the rubber material with the snow blade of the metal without replacing the snow blade. have. Of course, if the rear snow blade 132 is a plurality it will be apparent that more various snow blade replacement effect can be seen.
