Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a rough surface forming blade.

[Prior Art] Generally, snow removal work on a road is performed by a grader equipped with a snow removal blade, but it is difficult to completely remove snow on the road surface at that time, and the remaining snow is compacted by many vehicles and made into a mirror surface. , Frozen on the road.

The compacted and mirror-polished compacted snow is slippery and causes a vehicle slip accident and a pedestrian fall accident, and therefore needs to be quickly removed.

Conventionally, as a method of removing the compacted and mirror-polished pressure snow after the snow removal work, there are a method of spraying a chemical agent and a method of destroying it by a destruction device mounted on the rear portion of the grader.

[Problems to be solved by the invention] The method of spraying chemicals after snow removal work requires a reaction time until the effect of the chemicals appears, so it is not recommended for general vehicles that follow snow removal graders. , Ineffective and dangerous.

In the method of destroying with the destruction device attached to the rear of the grader, the visibility of the operator during work is deteriorated,
Due to the vehicle width of the grader body, it is difficult to destroy the pressed snow that has been mirrored over the entire width of the snow blade. In addition, the weight balance of the grader body is lost.

The present invention is proposed in view of the above points, and it is possible to destroy the compressed snow remaining on the road surface in real time after snow removal work, and to destroy the entire width of the snow removal blade, by performing the blade operation by the power tilt mechanism or manually. The operation is easy, and the operator of the snow removal grader
An object of the present invention is to provide a rough surface forming blade capable of performing the work of breaking the compressed snow at the same time as the conventional work of removing snow.

[Means for Solving Problems] In order to solve the above problems and achieve the object of the invention, a rough surface forming blade according to the present invention is characterized in that it is configured as follows. That is, a bit holder is attached to the blade main body or the rear portion of the edge of the blade, and a large number of bits are attached to the bit holder, and the large number of bits are arranged in parallel with the lower end portion of the blade main body or the edge lower end portion of the blade. It is characterized by being done.

[Operation] The specularized pressure snow remaining on the road surface after snow removal by the snow removal grader is destroyed in real time and in real time. Work to destroy,
Furthermore, these simultaneous operations are possible, and from the operator,
Because the work can be monitored at the same time as conventional snow removal work,
There is no problem in work safety.

Further, in the case of manual operation, the snow removal work and the work of destroying the mirror-finished compressed snow remaining on the road can be individually performed by the blade operation before the work, and these can also be performed simultaneously.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.
1 to 3 show the case of the first embodiment in which the bit holder is directly fixed to the rear portion of the edge of the blade, and FIG. 1 only performs the work of destroying the mirrored pressure snow remaining on the road. In this case, FIG. 2 is a side view showing the case where the snow removal work and the work of destroying the mirror-finished compressed snow remaining on the road surface are performed at the same time, and FIG. 3 is the case where only the normal snow removal work is performed.
FIGS. 4 to 6 show the case of the second embodiment in which the position of the bit holder is displaceably attached to the rear portion of the blade body, and FIG. 4 destroys the mirrored pressure snow remaining on the road. Fig. 5 shows the state of the rough surface forming blade when only the snow removal work and the work of destroying the mirrored pressure snow remaining on the road surface are performed at the same time when only the work is performed, and Fig. 6 is the case where only the normal snow removal work is performed. It is a side view which shows. Here, 1 is a blade main body, 11 is a blade edge, 12 is a bolt, 2 is a bit holder, 21 is a long hole, and 3 is a bit.

The first embodiment is a case where the bit holder 2 is directly fixed and attached to the rear portion of the edge 11 of the blade. A large number of bits 3 are attached to the bit holder 2, and the large number of bits 3 are arranged parallel to the lower end of the edge 11 of the blade. The distance between the bits 3 of many bits 3 is about 70 mm. In the present embodiment, FIG. 1 shows that the blade is tilted toward the front by the power tilt mechanism, and the edge used for normal snow removal work does not contact the road surface and remains on the road surface due to the edge (bit) for rough surface formation (mirror surface destruction). The case where only the work to destroy the mirrored pressure snow is performed is shown. Fig. 2 shows that both the edges used for normal road leveling work and the edges (bits) for rough surface formation (mirror surface destruction) contact the road surface, and the snow removal work and the mirrored pressure snow remaining on the road surface are destroyed. The case where work is performed simultaneously is shown. FIG. 3 shows a case where the blade is tilted forward so that an edge (bit) used for forming a rough surface (mirror surface destruction) is not brought into contact with the road surface and only normal snow removing work is performed.

In the case of the first embodiment, the operations in FIGS. 1 to 3 all represent the work with the power tilt mechanism, but in the model without the power tilt mechanism, rough surface formation (mirror surface destruction) ) To perform only the work of destroying the pressure snow, the work of removing snow and the work of destroying the pressure snow remaining on the road surface at the same time, and the case of performing only snow removal work. It can be carried out.

The second embodiment is a case where the position of the bit holder 2 is attached to the rear portion of the blade body 1 so as to be displaceable. A large number of bits 3 are attached to the bit holder 2 as in the first embodiment, and the large number of bits 3 are arranged parallel to the lower end of the blade body 1. The interval between the bit 3 and the bit 3 of many bits 3 is about 70 mm as in the first embodiment. In the second embodiment, FIGS. 4 to 6 show the case where only the work of destroying the compressed snow by forming a rough surface (mirror surface destruction) is performed, and the work of removing snow and destroying the compressed snow remaining on the road surface are simultaneously performed. , Shows the case where each work when only the snow removal work is performed using the power tilt mechanism.

In the case of the second embodiment, 2 formed on the bit holder 2
The bit holder 2 is fixed to the blade body 1 by two bolts 12 inserted through the individual elongated holes 21. The long hole
By appropriately selecting the position of the bolt 12 in the blade 21, the relative position between the blade body 1 and the bit holder 2 can be appropriately selected. Also in the case of the second embodiment, in a model not equipped with a power tilt mechanism, when only the work of forming a rough surface (destruction of the mirror surface) to destroy the compressed snow is performed, the snow removal and the destruction of the compressed snow remaining on the road surface are performed. It is possible to manually switch each work in case of simultaneously performing the above, and in the case of performing only the snow removal.

[Effects of the Invention] Since the present invention is configured as described above, when only roughening (mirror surface destruction) to destroy pressure snow, only snow removal and destruction of pressure snow remaining on the road surface are performed. When performing at the same time, three types of work, in which only snow removal work is performed, can be performed easily by using the power tilt mechanism, and moreover, because it is attached to the blade, the visibility for the operator is good, therefore It is also effective in terms of work safety. Since the blade is mounted on the blade in terms of work efficiency, the rough surface forming (mirror surface breaking) work has the effect of ensuring the blade width.

Further, the rough surface forming blade according to the present invention does not require the installation of a large-scale special device, and therefore has an effect of being inexpensive and easily attachable to the current organic device.
