Description

  The present invention relates to a windrow removing device that is provided in a wheel-type construction machine such as a wheel loader equipped with a bucket and a snow plow and is used for removing a windrow.

  Conventionally, in snow removal work on a traffic road, a wheel-type construction machine such as a snow removal truck, a rotary snow removal vehicle, a wheel loader equipped with a bucket or a snow plow has been generally used.

  When removing snow accumulated on the road with a bucket or snow plow when removing snow, the pushed snow overflows from the bucket or snow plow, and snow accumulation (windrow) occurs on both sides of the removed snow. .

  If a windrow occurs, it will hinder the traffic at the intersection. In addition, in a residential area, it may be a hindrance to pedestrians. For this reason, windrow removal is routine. As a method of removing windrows, there are a method of removing them in cooperation with a plurality of vehicles and a method of removing them by human hands.

  However, the above method has poor windrow removal efficiency. In view of this, a windrow removing device that increases the removal efficiency of the windrow is used.

  For example, when removing a windrow generated on a main road, a windrow removal device is attached to a large snow removal vehicle. However, it is not possible to remove a windrow generated on a narrow road such as a residential area because a large snow removal vehicle cannot enter. Moreover, it is not possible to deal with a case where there is no room for snow accumulation on one side of the road. These cases are dealt with by attaching a windrow removing device to the wheel loader (see, for example, Patent Document 1).

  In patent document 1, the side wing which is a windrow removal apparatus is provided in the right-and-left side surface of the bucket of a wheel loader. When removing the windrow, run with the side wings widened, and push the windrow with the side wings to collect snow in the bucket. This makes it possible to push snow having a width wider than that of the original bucket. Further, since it becomes easier for snow to collect in the center of the bucket, the filling efficiency of the windrow in the bucket is increased, and the removal efficiency of the windrow can be increased.

JP 2009-275435 A

  However, in snow removal in an urban area, running a certain distance to scratch the snow, the use of the side wing of Patent Document 1 has the following problems.

  When the amount of snow is large, the amount of snow to be pushed exceeds the capacity of the bucket, so that snow overflows from the bucket and windrows are generated on both sides of the road. For this reason, the wheel loader is moved to the right or left side of the road and a windrow is put in the bucket to carry it to the snow accumulation site. Therefore, in order to remove the windrow, the wheel loader must be reciprocated at least two times between the snow removal start position and the snow accumulation field, and the removal efficiency is poor.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a windrow removing device that can improve the efficiency of removing windrows in narrow roads such as residential areas and urban areas.

  As a result of diligent research, the present inventors have adopted the following windrow removal apparatus in order to solve the above-mentioned problems.

The windrow removal device of the present invention is provided on a wheel-type construction machine in which buckets or snow plows are attached to the front ends of left and right lift arms provided at the front of a vehicle body, and is used for windrow removal. A removal device,
The left and right lift arms are rearwardly and downwardly arranged on the left and right sides of the vehicle body so as to be able to move in the front-rear direction diagonally forward, projecting obliquely forward when the wheel-type construction machine is running, and cutting the windrow, The windrow snow thus obtained is provided with a pair of windrow removal plows that collect the snow on the center of the vehicle body.

The windrow removing device of the present invention is provided in a wheel type construction machine in which a bucket or a snow plow is attached to the front ends of left and right lift arms provided in the front portion of a vehicle body, and is used for removing windrows. A windrow removal device,
The left and right lift arms are arranged so as to be able to move forward and backward diagonally forward, projecting diagonally forward when the wheel-type construction machine is running, cutting the windrow, and the windrow obtained thereby It is characterized by comprising a pair of windrow removing plows that collect the snow on the center side of the vehicle body.

  In the windrow removal device of the present invention, a pair of windrow removal plows collects windrows generated during snow removal in narrow roads such as residential areas and urban areas at the center of the vehicle body, that is, at the center of the road. For this reason, since it becomes possible to remove the windrow only by reciprocating the wheel-type construction machine between the snow removal start position and the snow accumulation site, it is possible to remove the wheel-type construction machine that is required to remove the windrow than before. The number of round trips can be reduced. Therefore, the windrow removal apparatus of the present invention can increase the windrow removal efficiency in narrow roads such as residential areas and in urban areas.

  The cylinder cylinder 31 is fixed to the outer surface of the rear removal plate 212. The drive member 33 is fixed to the front portion of the outer surface of the front removal plate 211. The cylinder shaft 32 is configured to expand and contract in the oblique front-rear direction S by driving means (not shown). The driving means is driven by a driver's operation. The drive member 33 is configured to move the front removal plate 211 and the cutting edge 22 in the oblique front-rear direction S using the expansion and contraction of the cylinder shaft 32.

  As described above, the windrow removal device 10 is configured to move the windrow removal plows 21 and 21 (front removal plates 211 and 211) and the cutting edges 22 and 22 in the oblique front-rear direction S. As shown in FIG. 5, the arrangement position is set on the left and right outside of the moving range 12 a of the bucket 12 so as not to interfere with the bucket 12.

  Further, the windrow removing device 10 is configured to shrink the windrow removing plows 21 and 21 and the cutting edges 22 and 22 to near the width 12b of the bucket 12 when not in use.

  Using the wheel loader 1 configured as described above, a snow removal operation in a narrow road such as a residential area or an urban area will be described.

  First, the bucket 12 is lowered to a level state with the ground. At this time, since the windrow removing device 10 (windrow removing device main bodies 20, 20) is attached to the lift arms 11, 11, it is positioned horizontally with the ground like the bucket 12.

  Subsequently, the cylinders 30 and 30 are driven to project the windrow removal plows 21 and 21 obliquely forward, so that the width between the windrow removal plows 21 and 21 matches the road width.

  Next, the wheel loader 1 is caused to travel, and the snow accumulated on the road is pushed and removed by the bucket 12. As a result, the pushed snow is stored in the bucket 12. When a certain amount of snow is stored in the bucket 12, the snow overflows from the bucket 12. The snow overflowing from the bucket 12 accumulates outside the width of the bucket 12 (side the road) and becomes a windrow.

  When the windrow is generated in this way, the windrow removing device 10 cuts the windrow by the cutting edges 22 and 22. The broken snow is collected on the center side of the vehicle body 1a by the windrow removing plows 21,21. The snow collected on the center side of the vehicle body 1a is caused to flow behind the vehicle body 1a by the guide plate 23.

  As a result, windrow snow is collected in the center of the road after snow removal. On the other hand, the snow accommodated in the bucket 12 raises the bucket 12 and further raises the lift arms 11 and 11 in this state to be carried to the snow accumulation site and discarded. The snow collected in the center of the road is thrown away from the snow stored in the bucket 12 to the snow accumulation site, and then the wheel loader 1 is returned to the snow removal start position and removed using the bucket 12 and carried to the snow accumulation site. Throw away.

  As described above, in the windrow removing device 10 of the present embodiment, the windrows are collected on the road center side by the windrow removing plows 21 and 21. As a result, it is possible to remove the windrow only by making the wheel loader 1 reciprocate once between the snow accumulation field and the snow removal start position. Therefore, the number of reciprocations of the wheel loader 1 for removing the windrow can be reduced by one. Therefore, the windrow removal apparatus 10 of this Embodiment can raise the removal efficiency of the windrow in narrow roads, such as a residential area, and an urban area.

  Further, since the number of reciprocations of the wheel loader 1 necessary for removing the windrow is reduced by one, the number of reciprocations of the wheel loader 1 necessary for completing the snow removal work is also reduced by one, so that the work efficiency of the snow removal work can be increased. .

  Further, in the windrow removing device 10 of the present embodiment, the windrow removing plows 21 and 21 are configured to be movable in the oblique front-rear direction S. Thereby, the positions of the cutting edges 22 and 22 can be easily adjusted to the windrow. Therefore, it becomes possible to cut the windrow efficiently. Therefore, the windrow removal apparatus 10 of the present embodiment can further increase the windrow removal efficiency.

  Further, the windrow removing device 10 prevents the wheel loader 1 from being obstructed by shrinking the windrow removing plows 21 and 21 and the cutting edges 22 and 22 to near the width 12b of the bucket 12 when not in use. be able to.

  Moreover, in the windrow removal apparatus 10 of this Embodiment, the attachment position to the wheel loader 1 was set to the left-right side of the lift arms 11 and 11. For this reason, it becomes possible to attach and detach the windrow removing device 10 easily. Therefore, the work efficiency of the preparatory work before the snow removal work and the post-cleaning work after the snow removal work can be increased.

  In the windrow removing device 10 of the present embodiment, the cutting edges 22 and 22 are provided on the front end sides of the windrow removing plows 21 and 21. Since the cutting edges 22 and 22 extend from the front ends of the windrow removing plows 21 and 21 to the front of the vehicle body 1a, the cutting edges 22 and 22 can be cut from the rear of the windrow. Accordingly, it is possible to easily cut the windrow. Therefore, the windrow removal apparatus 10 of the present embodiment can further increase the windrow removal efficiency.

  Further, in the windrow removing device 10 of the present embodiment, the guide plates 23 and 23 are provided on the rear end side of the windrow removing plows 21 and 21. Since the guide plates 23 and 23 extend from the rear ends of the windrow removal plows 21 and 21 to the rear of the vehicle body 1a, the snow collected on the center side of the vehicle body 1a by the windrow removal plows 21 and 21 is removed. It becomes possible to efficiently flow to the rear of the vehicle body 1a. Therefore, the snow collected to the center side of the vehicle body 1a by the windrow removing plows 21 and 21 can be collected on the center side of the road without being scattered after traveling, and can be easily removed by the bucket 12. Is possible. Therefore, the windrow removal apparatus 10 of the present embodiment can further increase the windrow removal efficiency.

  Further, in the windrow removing device 10 of the present embodiment, each of the windrow removing plows 21 and 21 is constituted by two removing plates 211 and 212 divided in the front and rear, and the front removing plate 211 is formed. The windrow removal plows 21 and 21 are moved diagonally forward so as to protrude diagonally forward. For this reason, it becomes possible to reduce the weight of the removal board required for movement compared with the case where each of the windrow removal plows 21 and 21 is constituted by a single removal board. Can be moved with a small driving force. Therefore, the cost for driving the windrow removing plows 21 and 21 can be reduced.

(Second Embodiment)
FIG. 6A is a left side view from the middle part to the rear part of the wheel loader 101 showing the second embodiment of the present invention. FIG. 6B is a cross-sectional view taken along the line AA in FIG. In the present embodiment, the same parts as those in the first embodiment will be described with the same reference numerals.

  In the present embodiment, the windrow removing device 10 is attached below the front wheels 7, 7 and the rear wheels 6, 6 of the vehicle body 1a.

  More specifically, an under panel 18 is provided on the entire bottom surface of the rear portion 2 of the vehicle body 1a. The under panel 18 is formed in a concave shape in the left-right direction. The left and right side portions 18a, 18a of the under panel 18 are coupled to a main frame 2a forming a skeleton of the rear portion 2 of the vehicle body 1a.

  The windrow removing device 10 is attached to the outer surfaces of the left and right side portions 18a, 18a of the under panel 18 via third stays 19, 19. In addition, the attachment position of the windrow removal apparatus 10 is set to a position where it does not collide even if the front part 3 of the vehicle body 1a swings.

  By attaching the windrow removing device 10 below the front wheels 7 and 7 and the rear wheels 6 and 6 of the vehicle body 1a as described above, the windrow removing plow 21, compared to the case of the first embodiment, 21 and the cutting edges 22 and 22 are easy to enter the driver's field of view. For this reason, it becomes possible to easily adjust the width of the windrow removal plows 21 and 21 in accordance with the road width, and it is possible to efficiently cut the windrow. Therefore, the windrow removing apparatus 10 of the present embodiment can further increase the windrow removal efficiency as compared with the case of the first embodiment.

  The under panel 18 protects components such as the propeller shaft 2b provided on the bottom surface side of the rear portion 2. For this reason, when the windrow removal apparatus 10 collects snow on the center side of the vehicle body 1a and flows it backward, the under panel 18 can prevent the snow from coming into contact with the above-described components. Therefore, it is possible to prevent the wheel loader 101 from being adversely affected when the windrow is removed.

  Further, the under panel 18 also functions as a guide plate because the snow collected on the center side of the vehicle body 1a by the windrow removing plows 21 and 21 flows backward. Therefore, the windrow removing device may be configured by directly connecting the under panel 18 to the rear end side of the windrow removing plows 21, 21. As a result, the number of parts can be reduced, so that it is possible to increase the windrow removal efficiency while suppressing the cost and to prevent the wheel loader from being adversely affected during the removal of the windrow.

(Third embodiment)
FIG. 7A is a left side view from the middle part to the rear part of the wheel loader 301 showing the third embodiment of the present invention. FIG. 7B is a view of the wheel loader 301 viewed from the rear. In the present embodiment, the same parts as those in the first embodiment and the second embodiment will be described with the same reference numerals.

  In the present embodiment, the windrow removing device 10 is attached below the counterweight 5. Specifically, the windrow removing device 10 is attached to the bottom surface of the counterweight 5 via the fourth stays 40 and 40 and the attachment members 41 and 41.

  By attaching the windrow removing device 10 below the counterweight 5 in this way, the windrow removing plows 21 and 21 and the cutting edges 22 and 22 are more effective than when the windrow removing device 10 is attached to the lift arms 11 and 11. Makes it easier for the driver to enter the field of view. For this reason, it becomes possible to easily adjust the width of the windrow removal plows 21 and 21 in accordance with the road width, and it is possible to efficiently cut the windrow. Therefore, the windrow removing apparatus 10 of the present embodiment can further increase the windrow removal efficiency as compared with the case of the first embodiment.

  As mentioned above, although embodiment concerning this invention was illustrated, these embodiment does not limit the content of this invention. Various modifications can be made without departing from the scope of the claims of the present invention.

  For example, in the windrow removal apparatus 10 of the above-described embodiment, the case where each windrow removal plow 21 is configured by two plates has been described. However, the number of windrow removal plows 21 is not particularly limited, and may be constituted by three or more plates. In this case, the removal plate except for the rear end side is moved obliquely forward, and the windrow removal plow is configured to protrude obliquely forward.

  Further, each of the windrow removing plows may be constituted by a single plate. FIG. 8 and FIG. 9 show a windrow removal apparatus 110 including windrow removal plows 121, 121 formed of a single plate. In addition, in this windrow removal apparatus 110, the same code | symbol is attached | subjected to the part similar to the windrow removal apparatus 10 of said embodiment.

A mounting portion 123a for fixing the cylinder cylinder 31 is formed on the front portion of the guide plate 123 obliquely forward. When the cylinder shafts 32 and 32 are expanded and contracted in the oblique front-rear direction S by a driving means (not shown), the entire windrow removing plows 121 and 121 and the cutting edges 22 and 22 are moved in the oblique front-rear direction S.

  Since each of the windrow removing plows 121 and 121 is constituted by a single plate in this way, the number of parts of the windrow removing device 110 can be reduced, so that the manufacturing cost of the windrow removing device 110 can be reduced. Can be suppressed.

  Further, although the cylinder 30 is used as an actuator for driving each of the windrow removing plows 121, 121, the actuator is not limited to the cylinder 30, and other actuators may be used.

  In the embodiment, the case where the windrow removing device of the present invention is applied to a wheel loader equipped with a bucket has been described. However, the present invention is applied to a wheel loader equipped with a snow plow 50 (shown by a two-dot chain line in FIG. 2). You may apply the windrow removal apparatus of invention.
