Description

  The present invention relates to a snow removal processing machine, and more particularly, to a snow removal machine, a snow removal machine, or a snow removal processing machine that processes a lump of snow removed by manual work.

  In heavy snow areas such as Hokkaido and the Tohoku region, snow that has accumulated on roads and parking lots is removed by snowplows, snow removers, or manually, and the snow removed is piled up on the side of the road or in one corner of the parking lot. And if the amount of snow piled up becomes too great, traffic and life will be hindered, so the piled up snow is loaded into a dump truck by an excavator or the like and carried to a snow dump such as a riverbed and thrown away. Thus, in heavy snow areas, a great deal of effort is spent on snow removal. Here, if the snow removed from snow is allowed to flow in the side gutter on the roadside or in the nearby irrigation canal, the labor described above can be reduced. However, snow is less fluid than water, and snow removal is also possible. Since snow removed by a car or the like becomes a hard lump of snow, it is not possible to flow the removed snow directly into a gutter or a water channel.

  Therefore, as disclosed in Patent Document 1, it has been proposed to melt snow removed by heat and flow it through a side groove or the like.

JP-A-10-266153

  However, in order to melt the removed snow with heat, a large amount of heat energy is required to operate a heating device such as a burner or a heater.

  This invention is made | formed in view of the said situation, and makes it a subject to provide the snow removal processing machine which can change the snow which removed snow into sherbet-like snow and water with little energy, and can make it flow into a gutter.

The snow removal processing machine according to claim 1 is provided with a first processing unit that crushes a lump of snow removed by a rotary blade and a brush, and distributes the snow crushed by the first processing unit and the brush. And a second processing unit that is rubbed and refined.
The snow removal processing machine according to claim 2, further comprising a processing tank having an uneven surface therein, wherein the snow is refined by colliding the snow refined by the second processing unit against the uneven surface. Is further provided.
The snow removal processing machine according to claim 3 is provided in the first processing section, and is inclined by at least a part of the inclined plate that guides the lump of snow to be introduced to the rotary blade and the third processing section. A water storage tank for storing snow as water, and discharges water from the water storage tank to the inclined plate.

  In the snow removal processing machine according to the present invention, first, a lump of snow removed by the rotary blade of the first processing unit is crushed, but the crushed snow is still low in fluidity and is left as it is in a side groove or the like. However, it does not flow well. Then, the crushed snow is then distributed to the second processing unit provided with the brush. Then, the snow crushed in the first processing unit is rubbed with a brush to be refined to become sherbet-like snow or water. Therefore, it can be made to flow to a ditch etc. by processing the removed snow in the 1st processing part and the 2nd processing part. Here, in the present invention, since the snow removed from the snow is mechanically processed without depending on heat, it can be processed with less energy and flowed to the side groove or the like.

  If sufficient fluidity cannot be obtained by removing the snow from the first processing section and the second processing section, the processing in the third processing section is added to the side groove as in the invention of claim 2. And so on. In the third processing unit, the snow processed in the second processing unit collides with the uneven surface of the processing tank having an uneven surface inside, thereby further miniaturizing the snow in a sherbet shape. Thereby, sufficient fluidity | liquidity which flows favorably through a gutter etc. can be ensured about the snow removed.

  In the invention of claim 3, the inclined plate is provided in the first processing unit, and the thrown-in snow is guided to the rotary blade by the tilted plate, but the thrown-in snow adheres to the tilted plate, It is assumed that the snow does not move smoothly to the rotary blade. Then, the snow which was processed in the 3rd processing part and became at least one part is stored in a water storage tank, and the water stored in this water storage tank is discharged to an inclined board. This water discharge makes it easier for the snow to slip on the inclined plate, and the introduced snow can be smoothly guided to the rotary blade by the inclined plate.

  As described above, according to the present invention, sufficient fluidity cannot be obtained with only the first processing section. However, by providing a second processing section, the snow removed from the side grooves can be removed with a small amount of energy. It is possible to provide a snow removal processing machine that can flow into a gutter or the like instead of snow or water.

It is a side view which shows the outline of the snow removal processing machine which concerns on this invention. It is a top view of a 1st process part. It is a side view of a rotary blade. It is a longitudinal cross-sectional view of a 2nd process part. It is an enlarged view of the brush part shown in FIG. It is a top view of a 3rd process part. It is a top view which shows another example of a 3rd process part. It is a side view which shows another example of a water storage tank.

  An example as an embodiment of the snow removal machine according to the present invention will be described below. In addition, the snow removal machine of this example is mounted on a truck bed or mounted on a tow truck to be pulled by an automobile, etc. It can be quickly processed and flowed into a side groove or the like without being stacked aside. Moreover, it is not restricted to what follows a snowplow and a snowplow, but it can also operate | move timely and can process the snow piled up on the roadside etc.

  As shown in FIG. 1, the snow removal machine 1 of this example includes a first processing unit 10, a second processing unit 20, a third processing unit 30, and a water storage tank 40.

  As shown in FIGS. 2 and 3, the first processing unit 10 is provided with a rotary blade 11, and the snow (arrow A) thrown into the first processing unit 10 is a large lump. Then, it is finely pulverized by the rotary blade 11 and transferred to the next second processing unit 20 (arrow B). Here, in this example, the snow mass is crushed by a pair of rotary blades 11 that are driven to rotate in opposite directions (arrow C, arrow D) using a motor (not shown) as a drive source. Specifically, a pair of rotary blades 11 and 11 in which a large number of large-diameter blades 11a and small-diameter blades 11b are alternately arranged in the axial direction are arranged so that the large-diameter blades 11a and the small-diameter blades 11b face each other. The snow lump that is arranged side by side in the horizontal direction is crushed between the large-diameter blade 11a and the small-diameter blade 11b. Further, the outer peripheral surfaces of the large-diameter blade 11a and the small-diameter blade 11b have a gear-like uneven shape, and the snow mass is accurately crushed without slipping.

  As shown in FIG. 4, in the second processing unit 20, the brush 22 protrudes obliquely toward the center of the flow path 21 in the tubular flow path 21 through which the snow processed by the first processing unit 10 circulates. The snow lump that has been finely processed by the first processing unit 10 is finely rubbed by the brush 22 to become sherbet-like snow or water. Here, in this example, snow is drawn from the first processing unit 10 into the tubular flow passage 21 of the second processing unit 20 by the suction force of the pump 26 provided on the downstream side of the second processing unit 20. However, the present invention is not limited to this, and a pump 26 such as a blower may be disposed on the upstream side of the second processing unit 20 so that snow is sent from the pump 26 to the second processing unit 20.

  In this example, a wire brush formed of stainless steel is employed as the brush 22. Each brush 22 is provided so that its tip is inclined toward the direction of snow distribution (arrow E) so that the snow can move smoothly. Further, the installation density of the brush 22 on the upstream side of the second processing unit 20 is made coarser than that of the brush 22 on the downstream side, so that the snow can move smoothly. That is, the snow is gradually refined by gradually reducing the installation density from the upstream side, and is set so that the flow of the snow is not hindered by the brush 22. In addition, the opening space 23 formed by the tip of the brush 22 makes the opening space 23 on the upstream side of the second processing unit 10 wider than the opening space 23 on the downstream side, so that the snow moves smoothly. I can do it.

  Here, in this example, the roughness of the brush 22 and the width of the opening space 23 formed by the tip of the brush 22 are different in three stages, but not limited to this, two stages or four stages It may be different as described above, or may be continuously changed steplessly. The roughness of the brush 22 and the width of the opening space 23 do not prevent the brush 22 from reaching the entire length of the flow passage 21 and being uniform. Furthermore, the flow passage 21 is not limited to a tubular shape, and may be a bowl-shaped flow passage 21 with an open upper portion as a mode in which snow moves due to its own weight.

  Incidentally, as shown in FIG. 5, the brush 22 may have a large number of split ends 25 extending from the trunk hair 24 for each one, and snow may be rubbed finely by the split ends 25. In the case where the split ends 25 are provided on the trunk hair 24, when the split ends 25 have a direction opposite to the snow circulation direction E as shown in FIG. be able to. On the other hand, if the split ends 25 have a direction that conforms to the snow distribution direction E, as shown in FIG. 5B, a great amount of unnecessary resistance of the brush 22 against snow can be suppressed.

  The sherbet-like snow or water processed by the second processing unit 20 is discharged from the upper part into the processing tank 31 of the third processing unit 30 by the pump 26 (arrow F). And in the 3rd processing part 30, it controls and manages using a water level sensor so that the sherbet-like snow or water in the processing tank 31 may become below the predetermined water level G, and the water level of the processing tank 31 is predetermined. When the water level G is exceeded, the pump 33 is operated to discharge the sherbet-like snow or water in the processing tank 31 to the water storage tank 40 (arrow H). Further, as shown in FIG. 6, an uneven surface 32 is provided in the processing tank 31 at a position close to the inner wall. When sherbet-like snow or water is discharged from the processing tank 31 by, for example, providing a guide plate that forms a vortex around the discharge port below the processing tank 31, it becomes a vortex (arrow I) and collides with the uneven surface 32. It is supposed to be. As a result, the sherbet-shaped snow collides with the uneven surface 32 and is further refined, and its fluidity approaches that of water and can flow into a side groove or the like.

  Here, in this example, the concavo-convex surface 32 is formed by the expanded metal disposed in the processing tank 31, and the concavo-convex shape of the concavo-convex surface 32 is a lattice shape. A plurality of holes may be formed in a shape, and the uneven surface 32 may be formed by this thin plate. Furthermore, the uneven surface 32 is not limited to the uneven surface 32 formed by another member such as expanded metal or a thin plate, and the inner peripheral surface of the processing tank 31 may be formed on the uneven surface 32 by providing unevenness on the inner peripheral surface of the processing tank 31. .

  Further, the collision of the sherbet-shaped snow with the uneven surface 32 is not caused by the vortex generated by the drainage from the processing tank 31, but by the pump 26 from the second processing unit 20 as shown by the two-dot chain line in FIG. 7. The sherbet-shaped snow or water that has been transferred is jetted in the circumferential direction of the processing tank 31 from the charging hole provided in the upper side wall of the processing tank 31 by, for example, branching the flow pipe in the middle, and sprayed on the uneven surface 32. You may make it attach (arrow J). Note that the vortex may be forcibly generated by agitating a motor by driving a stirrer in the processing tank 31.

  The sherbet-like snow or water processed by the third processing unit 30 is discharged to the upper portion of the water storage tank 40 by the pump 33 (arrow H). The water storage tank 40 is controlled and managed using a water level sensor so that the sherbet-like snow or water is above the lower limit water level K and below the upper limit water level L, and the water level of the water storage tank 40 is at the upper limit. When the water level L is exceeded, the discharge valve 41 is opened, and the sherbet-like snow or water in the water storage tank 40 is discharged into a side groove or the like (arrow M).

  On the other hand, if the discharge continues and the water level of the water storage tank 40 falls below the lower limit water level K, the discharge valve 41 is closed and the water level of the water storage tank 40 rises. This is to effectively use water that is reliably liquid in the lower part of the water storage tank 40. That is, in this example, as shown in FIGS. 1 and 2, the first processing unit 10 is provided with an inclined plate 12 that guides the thrown-in snow to the rotary blade 11. This is because the sherbet-like snow rises to the upper layer part and the water falls to the lower layer part due to the difference in specific gravity, so that the water in the lower layer part is transferred and discharged to the upper surface of the inclined plate 12. Specifically, the water in the lower portion of the water storage tank 40 is pumped up by the pump 42 and discharged through the transfer pipe 43 to the upper surface of the inclined plate 12 of the first processing unit 10 (arrow N). As a result, the snow can easily slip on the inclined plate 12, and the snow thrown into the first processing unit 10 is favorably guided to the rotary blade 11 by the inclined plate 12.

  As mentioned above, although an example of the snow removal processing machine 1 was demonstrated, this invention is not limited to the above-mentioned example, In the range which does not deviate from the summary of this invention, an appropriate change is possible.

  For example, not only the sherbet-like snow or water in the water storage tank 40 is discharged to the outside by its own weight by the operation of the discharge valve 41 but also forcedly discharged to the outside by the pump 44 as shown in FIG. You may make it do (arrow P). In this case, the pipe to be discharged to the outside is branched, and a part of the water (arrow O) pumped up by the pump 44 is passed through the transfer pipe 43 and discharged to the inclined plate 12 (arrow Q). Further, as shown in FIG. 8B, the water storage tank 40 has a structure in which the upper sherbet-like snow or water overflows, and discharges the overflowing sherbet-like snow or water to the outside (arrow R). A pump 45 may be disposed in the lower part of the water storage tank 40, and the water in the lower part of the water storage tank 40 may be discharged from the transfer pipe 43 to the inclined plate 12 by this pump 45 (arrow S).

  Furthermore, although illustration is abbreviate | omitted, the 4th process part provided with the brush 22 similar to the 2nd process part 20 was expanded between the 3rd process part 30 and the water storage tank 40, and by this 4th process part, Further, the sherbet-like snow may be further refined. In this case, by making the brush 22 of the fourth processing unit a finer brush than the brush 22 of the second processing unit 20, further miniaturization of the sherbet-like snow can be suitably achieved.

  Note that the present invention does not completely exclude melting by heat in the processing of snow removed. That is, at appropriate locations such as the processing tank 31 and the water storage tank 40 of the third processing unit 30, a heating means such as a burner or a heater is added as an auxiliary to heat or melt the sherbet-like snow. You may make it heat and heat the cold water immediately after.
