Description

Snow plow car having up-and-down moving and side rolling blabe}

The present invention relates to a snowplow having blades, and more particularly, to a snowplow having a lifting movement and left and right rollable blades in which continuous snow removal operations can be continued without a separate operation of the driver even when the road surface is inclined or dents.

In general, a snow removal vehicle (for example, a tractor) provided with blades is used for road snow removal. The snow removing vehicle can adjust the direction of the blade. Therefore, the snow removal vehicle removes snow from the road quickly while simultaneously performing snow removal and topdressing using a blade.

In this process of snow removal, the blade is controlled by the operator appropriately to the condition of the road surface. However, there is a situation where it is difficult to control the direction and attitude of the blade by the operator. For example, it is difficult to change the direction and attitude of the blade in the case where the road surface is inclined in one of the width directions or suddenly dents.

As a background technology of the present invention, a 'snow plow buffer' is proposed as Korean Patent Registration No. 10-0369931. It is attached to the mounting plate formed on the front of the large truck to remove the snow accumulated on the road, and has a predetermined width and size, the upper and lower body rear is provided with a connecting portion provided with a hinge groove, the upper end A fastener is formed in the center part, and the intermittent plate is located at both sides of the snow removal plate, and the rear side of the snow removal plate is positioned at a predetermined interval, and the mounting portion having a rotation groove on the front and bottom of the body is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

The snow removing machine applied to the present embodiment is provided with a blade support frame 10 detachably connected to the boom device 2 connected to the vehicle as shown in FIGS. 1 to 3. The boom device 2 includes a boom stand 2a, a boom cylinder 2b, an attachment cylinder 2c and a link mechanism 2d. Therefore, the blade support frame 10 can be lifted and lowered by the boom cylinder 2b, and the rotation operation is possible by the attachment cylinder 2c. The blade support frame 10 is connected to the boom 2a and the link mechanism 2d through pin coupling.

The blade support frame 10 is provided with pin brackets 11 and 11 at the rear and has a pivot arm 12 protruding from the front center thereof. The pivot arm 12 is connected to both ends of one end of the top and bottom loads 20 and 20, and the cutoff of the top and bottom cylinders 20 and 20 is connected to the blade 30. In addition, the blade 30 is pivotally connected to the blade support frame 10 so that the left and right angles are adjusted by the clay cylinders 20 and 20.

At this time, both the top and bottom cylinders 20 and 20 are spherically connected to the pivot arm 12 and the blade 30 side. This is for the blade 30 to be rolled about the Y axis.

The pivot bracket 40 is installed at the center of the rear rear side of the blade 30 as shown in FIGS. 3 and 4. The pivot bracket 40 is installed by inserting the pivot pin 60 in the Z-axis direction. The blade 30 is installed to be able to tilt back and forth about the hollow fixed shaft 36 connected to the pivot bracket 40. In addition, the front and rear tilt angles of the blade 30 are limited by the stoppers 39 and 39 fixedly installed at both ends of the hollow fixed shaft 36. In addition, the blade 30 is capable of returning to its original position after it has been tilted back and forth by a pair of torsion bars (not shown) provided in the hollow fixed shaft 36 in the axial direction.

On the other hand, the pivot arm 12 of the blade support frame 10 is provided with a hollow pin bushing 50 so that the pivot pin 60 is inserted. The pin bushing 50 is inserted into the cylindrical boss 55 fixed to the pivot arm 12 and fixed by the cover plate 57.

The pin bushing 50 is provided with a bushing hole 51 into which the pivot pin 60 is inserted. At this time, the cross section of the bushing hole 51 of the pin bushing 50 is configured to be larger than the cross section of the pivot pin 60 so that the blades may be formed by the rolling gap R formed between the pin bushing 50 and the pivot pin 60. The left and right rolling of 30) is made.

The rolling gap R can be made by two methods.

In the first method, as shown in FIG. 5A, the pin bushing 50 and the pivot pin 60 are assembled to have a circular cross section so that the rolling gap R occurs all over the circle.

In the second method, as shown in FIG. 5 (b), the pin bushing 50 has an elliptical cross section and the pivot pin 60 has a circular cross section so that the rolling gap R is formed on the left and right sides in the X-axis direction.

As described above, a rolling gap R is formed between the pin bushing 50 and the pivot pin 60 so that the blade 30 is inclined to the left or the right even when the blade support frame 10 is not moved. It can be rolled as shown in Figs. 6 (b) and (c) in the inclined direction to perform the function of snow removal.

On the other hand, during the removal of the blade 30 as shown in Figure 7 (b) is a recessed part of the recess, for example, when encountering a puddle has the following structure to continue to perform snow removal without the operator's operation separately.

That is, the length of the pin bushing 50 is smaller than the length of the pivot pin 60 so that the blade 30 is moved up and down relative to the blade support frame 10 so that the pivot arm 12 and the pivot bracket 40 It can be configured to have a constant lifting stroke (L) as shown in FIG.

Therefore, since the blade 30 is in a rising position on the normal road surface, the lifting stroke L is located on the upper side of the pin bushing 50 as shown in FIG. Relatively, the pin bushing 50 is located on the lower side of the pivot pin 60. At this time, when the blade 30 reaches the depression in the state where the lower side snow blade of the blade 30 is in contact with the road surface as shown in Fig. 7 (a), the pivot pin 60 moves downward by its own weight. At the same time, the blade 30 is automatically moved downward. Therefore, even if there is no separate operation by the operator, the snow removal operation of the blade 30 is continued in the depression.

The operation of the present embodiment thus configured will be described.

First, the blade 30 is positioned on the road surface as shown in FIG. 7A by the operator's operation of the boom device 2 to remove the road road surface. At this time, the snow removal blade of the blade 30 is operated in close contact with the road surface.

Next, when the road surface is inclined to either side in the width direction during snow removal, the blade 30 is rolled along the inclined direction. That is, the blade 30 is inclined with respect to the Y-axis direction of the pivot pin 60 of FIG. 3. This occurs automatically because the pivot pin 60 has a rolling gap R in the pin bushing 50 as shown in FIG. At this time, the vertical posture of the pivot pin 60 is changed to have a posture inclined to one side as shown in (b) or (c) of FIG. 6. Therefore, even if the road surface is inclined in any way, the blade 30 has a rolling posture that cannot be controlled by the operator and can effectively perform road snow removal.

On the other hand, when the blade 30 meets the recessed place during snow removal, as shown in Fig. 7 (b), the blade 30 is lowered by its own weight. This is possible because the blade 30 has an elevating stroke L as shown in FIG. 8, which can elevate on the pivot arm 12 of the blade support frame 10. Therefore, even if the operator does not separately control the operation of the blade 30, the snow removal operation is continued in the depression and the snow removing ability is improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
