Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dirt scrape-up plow used for cleaning roads.

[Conventional technology and technical issues to be solved]

Every spring, a large amount of dirt accumulates on roadsides in snowy countries, creating a dangerous situation. This is because during the winter, as snow on roads is repeatedly moved to the roadside and removed, sand and dust are scattered evenly over the entire road.
This is because the snow is collected along with the snow that is removed along with the roads. Moreover, the dirt and sand that accumulates on the roadside hardens with water from melting snow, and becomes extremely solid on the road. Not only does this accumulated sediment spoil the city's beauty, but it also harms people's health by getting picked up by spring winds and floating in the air, getting into the lungs or eyes. In addition, car tires sometimes slip on the accumulated dirt, causing traffic accidents. For this reason, after the snow melts, removing dirt and cleaning from roadsides is an essential part of road maintenance work.

However, conventional methods for removing and cleaning dirt from the roadside involve either a cleaning worker loading the dirt from the road directly onto a truck with a shovel, or a cleaning worker raking the dirt into a pile and then sucking it up with a wiper. This is the only method available, and it is extremely labor-intensive and expensive, and since the work is done on roads where cars come and go, it obstructs traffic and has the disadvantages of causing accidents for cleaning workers.

The present invention has been made in view of the above-mentioned drawbacks of conventional cleaning operations.The present invention saves labor in cleaning accumulated dirt near roads, increases cleaning efficiency, does not obstruct traffic, and is safe. The technical challenge is to provide a completely new device that can perform the following tasks.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above problem will be described below with reference to the accompanying drawings.

That is, a first fluid pressure operated cylinder 14 is installed upright on a chassis 1 which is a working vehicle, and a climbing frame 5 is provided so as to move up and down by the expansion and contraction of this fluid pressure operated cylinder 14. The fixed ends of the arms 3a, 3 are pivotally mounted on the second hydraulic cylinders 7a, 7, and one end of the arms 3a, 3 is pivotally supported on the climbing frame 5.
The other end of b is connected to the arms 3a, 3b, and the arms 3a, 3 are expanded and contracted by the cylinders 7a, 7b.
so that the open end of b swings up and down, and
At the bottom of a, 3b are shear pin hinges 9a, 9b,
Earth and sand plows 2a and 2b are vertically disposed with 9c and 9d and the shear pin hinges are spaced apart from each other,
The earth and sand plows 2a and 2b are fixed with shear pins S, S, S, and S that break on impact, so that earth and sand cleaning work can be carried out safely, quickly, and with less labor. Provided soil scrape-up plow.

〔Example〕

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

A suspension frame 11 and a suspension bracket 13 are attached to the front of a chassis 1, which is a work vehicle, and the suspension bracket 13 is located above the suspension frame 11.
First hydraulically actuated cylinder 14 with suspension pin 18
The suspension frame 11 is provided with slide rails 12 vertically on both left and right sides, and the climbing frame 5 on which the first hydraulic cylinder 14 is suspended moves up and down on the slide rail 12 by the expansion and contraction of the cylinder 14. can do.

The climbing frame 5 has an arm hinge 6a,
6b, above which are cylinder hinges 16a, 16b.
The arm hinges 6a, 6b pivotally support the fixed ends of the arms 3a, 3b in a spread forward state by the hinge pins 4a, 4b, and the cylinder hinges 16a,
16b pivotally supports one rod end of the second hydraulic cylinder 7a, 7b by means of pins 17a, 17b. The other rod ends of the second hydraulic cylinders 7a, 7b are connected to lifting brackets 15a, 15b at the open ends of the arms 3a, 3b, respectively. As a result, the second fluid pressure operating cylinder 7a,
The open ends of the arms 3a, 3b can swing in the vertical direction by expanding and contracting the arms 7b.

A shear pin hinge 9 is provided below the arms 3a and 3b.
a, 9b, 9c, and 9d, and the shear pin hinges 9a, 9b, 9c, and 9d pivotally support the earth and sand plows 2a and 2b by hinge pins 10a, 10b, 10c, and 10d, and the shear pins S and S.・The earth and sand plows 2a and 2b are latched by S/S. There is a gap between both earth and sand plows 2a and 2b, and earth and sand is raked behind this gap during cleaning work. When a large force is applied to either of the earth and sand plows 2a and 2b, the shear pin breaks and the earth and sand plow rotates, so that the earth and sand plow is not damaged.

Although the present embodiment is configured as described above, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the claims. In particular, it is within the scope of the present invention to be able to change the forward opening angle of the arm.

[Effects of the present invention]

As explained above with reference to the embodiments, the soil scrape-up plow of the present invention is such that when the work vehicle runs on the road with the plow in contact with the ground, the soil on the road is scraped up along the plow, and the soil is scraped up between the left and right plows. It passes through the gap and remains behind the vehicle, forming an embankment a little distance from the side of the road. By raking up the earth and sand, it becomes possible to use a wiper suction as it is, or there is an effect that it does not take much time when loading it onto a truck, etc., which not only saves labor, but also reduces the work time. It saves time and allows work to be done without interfering with traffic.
Alternatively, you can work safely by aiming for times when traffic is light. In addition, the location where the dirt accumulates is located away from the roadside, making it easier to perform wiper suction. Alternatively, the climbing frame moves up and down, making it easy to move when not working. Furthermore, since the open ends of the left and right arms can be swung up and down independently, the soil plow can easily respond to the slope of the road, allowing for effective soil cleaning and removal work even on sloped road surfaces. .

As described above, the soil scrape-up plow of the present invention achieves labor saving, speeding up, and safety in roadside soil removal and cleaning work, and has great industrial utility value.
