Description

  The present invention generally relates to snow pressure devices. More specifically, the present invention relates to a snow pressure device that ensures smooth passage of a vehicle or a person by reducing the volume of the snow that has accumulated on the road against the road surface (reducing the volume).

  In snowfall areas, how to deal with snow that has fallen in winter has become an important issue. Local governments in snowfall areas, etc., make a huge budget every year and carry out snow removal work, but such snow removal work is a great burden on the finances of exhausted local governments.

  The present invention has been developed in view of such circumstances, and does not remove (remove) the snow that has accumulated on the road, but presses it against the road surface to reduce the volume, thereby facilitating smooth traffic. The object is to provide a snow snow device to be realized.

Snow groomer device according to the claims 1, is mounted on the arm tip of Wheel Loader removal of the bucket, and groomed plate for pressing the snow Furitsumo' the road surface, the connecting arm to the vehicle body of the rear end of the tire shovel And a compaction machine for further compacting the snow compressed by the snowboard and for applying unevenness to the snow surface, the snowboard being a rectangular flat metal as a whole Or a rectangular metal plate that is convexly curved in the direction of travel of the snow pressure device, and the mounting angle in a side view of the pressure snow plate is such that the pressure snow plate is a flat metal plate. In this case, the plane and the road surface constituting the plate are 20 ° to 30 °, and when the pressure snow plate is a convex metal plate, it passes through the most curved portion at the center of the plate and the lower edge of the plate. The line and the road surface should be 20 ° -30 ° And the mounting angle in plan view of the pressure plate is such that the line perpendicular to the boundary between the sidewalk and the roadway and the center line of the pressure plate are 20 ° to 30 °. It is characterized by .

The snow pressure device according to claim 2 of the present invention is attached to the tip of an arm extending rearward from the attachment point of the front wheel of the grader from which the leveling plate has been removed, and a pressure snow plate for pressing the accumulated snow against the road surface, behind the location from a location above groomed plate between the front and rear wheels of the grader, the arm is mounted rotatably via different arms and further rolling snow compressed by the pressed snow board A pressure machine and a rolling machine for applying irregularities to the snow surface, and the pressure snow plate is formed of a rectangular flat metal plate as a whole, or a rectangle curved convexly toward the direction of travel of the snow pressure device When the pressure snow plate is a flat metal plate, the plane and the road surface constituting the plate are 20 ° to 30 °, The pressure plate is convex gold In the case of a genus plate, a line passing through the most curved portion of the central portion of the plate and the lower edge of the plate and the road surface are configured to be 20 ° to 30 °, and in the plan view of the compressed snow plate The mounting angle is configured such that a line orthogonal to a boundary line between a sidewalk and a roadway and a center line of the compressed snow plate are 20 ° to 30 ° .

According to a third aspect of the present invention, in the snow snow device of the first or second aspect, the compactor is formed by a cylindrical roller having a large number of protrusions on the peripheral surface, or a chain is mounted. Further, it is formed by a plurality of tires.

According to the snow pressure device of the present invention, it is possible to ensure smooth traffic during the winter period in a snowy area at a lower cost than snow removal. In addition, since the snow pressure device of the present invention uses existing construction machines ( tire excavators, graders ), manufacturing costs and maintenance costs can be kept low. Furthermore, in the snow pressure device according to the present invention, the snow pressure surface is uneven by the rolling compactor, so that it is possible to obtain good braking of the vehicle.

(First embodiment)
Next, with reference to the drawings, a snow snow device according to a preferred embodiment of the present invention will be described in detail. 1 and 2, the snow pressure device according to the first embodiment of the present invention generally indicated by reference numeral 10 includes a snow pressure plate 14 attached to the tip of an arm 12 a of a tire shovel 12.

  As shown in FIG. 3, the snow plate 14 is formed of a rectangular flat metal plate as a whole, and is firmly fixed to the arm 12a via any appropriate fastener (not shown). (In FIG. 1 and FIG. 2, reference numeral 12b indicates a hydraulic cylinder).

  Preferably, a road surface protection member 14a is installed on both sides of the snow pressure plate 14 on the side in contact with the road surface. The road surface protection member 14a is for preventing the road surface (asphalt surface) from being damaged by the pressure snow plate 14 during the snow pressure work. In addition, although the road surface protection member 14a is illustrated as having a disk shape, any other known shape may be used.

  Mounting angle formed by the snowboard 14 in a side view with respect to the road surface (as shown in FIG. 4 (a), the angle formed clockwise with respect to the road surface when viewed from the snowboard device 10 moving to the left) ) Α is preferably 20 ° to 30 °, most preferably 25 °. The mounting angle α of the pressure snow plate 14 is defined in this way because such an angle can compress snow most efficiently. More specifically, when α is 20 ° or less, snow slips over the pressure plate 18 and the snow cannot be compressed accurately. When α is 30 ° or more, the snow is pushed forward. This is because the snow is not compressed (ie, it looks as if it is removing snow).

  Mounting angle formed by the snowboard 14 in a plan view (as shown in FIG. 4 (b), when viewed from the snowboard device 10 traveling leftward, with respect to a line y orthogonal to the boundary line x between the sidewalk and the roadway The angle (clockwise) β is preferably 20 ° to 30 °, and most preferably 25 °. The mounting angle β of the pressure snow plate 14 is defined in this way because such an angle can compress snow most efficiently. More specifically, if β is 20 ° or less, snow cannot be pushed out to the roadway side, and snow remains on the sidewalk or crossroads. This is because it is pushed out too much to the side and snow that is not compressed is left about one third.

  The point that the preferable angles of α and β are as described above is based on the results of various experiments conducted by the inventors. The results of this experiment are shown below (note that the experiment was carried out using a tire shovel manufactured by Hitachi Construction Machinery, when the snowfall was 20 cm to 35 cm).

(1) Experimental results regarding α When α = 10 °, the snowboard was almost horizontal to the snow surface, and the snow slipped from the upper side of the snowboard. In the case of α = 13 ° to 15 °, the result was almost the same as that in the case of α = 10 °, and the snow slipped from the upper side of the pressure snow plate, and it was not possible to press the snow. In the case of α = 20 ° to 30 °, the snow could be efficiently compressed (in particular, the snow pressure effect in the case of α = 25 ° was very good). In the case of α = 33 ° to 35 °, the snow was excessively pushed in the traveling direction of the snow pressure device, so that a large amount of snow was formed and the required snow pressure could not be achieved. In the case of α = 40 ° to 45 °, a larger amount of snow was made than in the case of α = 33 ° to 35 °, which was an obstacle to running of the vehicle.
(2) Experimental results on β When β = 5 ° to 10 °, a lot of snow remains on the left side of the direction of travel of the snow pressure device, and the tire of the snow pressure device rises on the remaining snow. The part on the left side of the driver's seat of the snow pressure device tilted about 15 cm, which hindered the operation of the snow pressure device. In the case of β = 13 ° to 18 °, although somewhat improved compared to the case of β = 10 °, a snow ball (30 to 35 mm) remains on the left side in the traveling direction of the snow pressure device. I couldn't drive while holding. In the case of β = 20 ° to 30 °, it was possible to efficiently compress the snow (particularly, the snow pressure effect in the case of β = 25 ° was very good). In the case of β = 35 °, about 2/5 of the snow was pushed out to the opposite lane, which hindered the passage of oncoming vehicles (when the traveling speed was 20 km / h, this tendency It became even more prominent). In the case of β = 40 ° to 45 °, even if α = 25 °, about 1/2 snow was pushed out to the opposite lane.

  The snow pressure device 10 also includes a compactor 16 rotatably mounted on the rear portion of the tire shovel 12. The compactor 16 is formed by a cylindrical roller, and a large number of protrusions 16a are provided on the peripheral surface of the roller for making irregularities on the snow surface. The rolling compactor 16 serves to further compress the snow reduced in volume by the pressure snow plate 14, and also serves to add unevenness for braking the vehicle to the compressed snow surface. In FIG. 2, reference numerals 16b, 16c, 16d, 16e, and 16f represent power supply coils for a connecting arm, a towed part connector, a taillight / braking light, a reflector, a taillight / braking light, etc. (Taillights, brake lights, etc. shall conform to safety standards based on the Road Transport Vehicle Law).

The experimental results verifying the action of the compactor 16 in the snow pressure work are shown below (the experiment is selected when the snowfall is 20 cm to 35 cm, and the wood crusher tab grinder manufactured by Morooka Co., Ltd. is used as the compactor. The rotary crushing shaft part mounted on the MC5000 (530HP) was taken out and pulled to the rear part of the tire shovel).
(1) When a snow-crushing operation is performed using only a snow-crushing plate without using a roller compactor If a truck of 4 tons or more is driven on the road surface after the snow-crushing operation, stable traveling is possible when going straight, but turning is impossible when turning right or left became. In addition, as for ordinary passenger cars (FF, FR), after traveling several meters, the tire slipped and the tire slipped.
(2) When snow compaction work is performed using both the compaction machine and snow compaction board Even if a 4t truck or more and a 2-axis 11t dump truck are run on the road surface after snow snow work, the car runs stably and when turning right or left There was no hindrance. Also, ordinary passenger cars (FF, FR) ran without any problems during straight running, right turn or left turn.
(3) Summary From the above experimental results, the compression of snow using only the pressure snow plate does not provide stable vehicle travel, and it is not possible for the vehicle to travel for the first time after performing snow pressure work using both the compaction machine and the pressure snow plate. It was confirmed that there was no snow-capped road surface.

  In the above embodiment, the pressure snow plate 14 is formed of a flat metal plate. However, as shown in FIG. 5, a rectangular metal plate curved in a convex shape toward the traveling direction of the snow pressure device 10. The snow plate 14 'may be formed. The snow plate 14 'is fixed to the arm 12a via a universal arm joint portion 14'b of the snow plate 14' via any appropriate fastener (not shown). The degree of curvature of the snow plate 14 'is preferably a curved distance d = 0.10D to 0.15D at the center of the snow plate 14' with respect to the length D in the short side direction of the snow plate 14 '. = 0.12D is most preferable (see FIG. 5B). It is preferable that the mounting angles α ′ and β ′ of the snow plate 14 ′ are the same as the mounting angles α and β when the snow plate 14 is used (see FIGS. 5B and 5C). According to an experiment conducted by the present inventor, it was confirmed that when the curved snow plate 14 'is used, an even better snow snow effect can be obtained as compared with the case where the flat snow plate 14 is used. . FIG. 6 is a side view showing the snow pressure device 10 equipped with the snow pressure plate 14 '.

(Second Embodiment)
FIG. 7 is a side view showing the snow pressure device 20 according to the second embodiment of the present invention, and FIG. 8 is a plan view of the snow pressure device 20. In the snow pressure device 20, the pressure snow plate 24 and the compactor 26 are mounted on the grader, and the compactor 26 is mounted between the front and rear wheels of the grader, not the rear part of the grader. Except for the point, it has substantially the same configuration as the snow pressure device 10. That is, the snow pressure device 20 includes a pressure snow plate 24 attached to the tip of the arm 22a of the grader 22, and a compactor 26 attached to the arm 22b between the front wheel and the rear wheel of the grader 22.

  In the snow pressure device 20, the compactor 26 is attached to the arm 22 b between the front wheel and the rear wheel of the grader 22. The compactor 26 is connected to a hydraulic cylinder located between the front wheel and the rear wheel of the grader 22. This is because it is possible to press the rolling compactor 26 against the snow-capped surface, and thereby more efficient snow-carrying work can be expected. Considering that the operation of the grader 22 is suitable for a wide area and that the compactor 26 can be pressed against the snow-capped surface, the snow-crusher 20 is suitable for snow-crane work on a relatively large road. .

  A road surface protecting member 24 a is installed on the pressure snow plate 24, as with the snow pressure plate 14, and a number of protrusions 26 a are provided on the circumferential surface of the pressure roller 26, as with the pressure roller 16. Further, the mounting angles α and β of the snow plate 24 are each preferably 20 ° to 30 °, most preferably 25 °, similarly to the snow plate 14. Further, when the snowboard plate 24 'having a curved shape is used (see FIG. 9), a better snow snow effect can be obtained.

  Next, the use of the snow snow device 10 configured as described above will be described. First, the snow pressure device 10 is installed at a place where the snow pressure work is to be performed, and the snow pressure device 10 (tire excavator 12) is advanced. Then, the accumulated snow is compressed by being pressed by the pressure snow plate 14, and then the compressed snow is further compressed by the compactor 16, and unevenness is given to the snow surface by the protrusions 16 a provided on the peripheral surface of the compactor 16. It is done. In this way, since the snow is compressed with the unevenness on the snow surface, smooth traffic of vehicles and people is ensured. The use of the snow pressure device 20 is the same as that of the snow pressure device 10.

  There is a concern that if the snow is continuously applied, the snow layer on the road surface accumulates and the thickness becomes considerable. In order to verify this point, the present inventor measured the accumulated thickness of the compressed snow layer when the compressed snow work was continued for one season. It was confirmed that the maximum deposition thickness was about 15 cm on a small and medium-sized road of 8 m width, and that the deposition thickness was about 5 cm to 8 cm on a highway with large traffic (buses, trucks, etc.). The reason why the accumulated thickness throughout the season falls to this level is presumed to be due to the compression of snow by the snow pressure device, the melting of snow by the exhaust heat of the vehicle and solar radiation. Considering that the thickness of the snow-capped layer is reduced to this level and that the surface of the snow-capped surface is uneven by a rolling mill, it is predicted that there will be no hindrance to vehicle traffic.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is something.

For example, in the above-described embodiment, the compactor 16 is formed by a cylindrical roller having a large number of protrusions 16a on the peripheral surface, but as shown in FIG. 10 (a ), the chain 16'a A plurality of tires 16 'mounted with may be used as a compactor. Alternatively, as shown in FIG. 10 (b ), a plurality of tires 16 'may be used in duplicate. 10 (a) and 10 (b ), reference numerals 16'b, 16'c, 16'd, 16'e, and 16'f denote a connecting arm and a towed object as in the above embodiment.
