Description

The present invention relates to a scraping-type soil removal system for a vehicle sediment removing device. Specifically, a movable soil discharging plate for scraping sediment and the like accumulated in a narrow area under the pedestal of a vehicle sediment removing device is arranged under the pedestal. However, the present invention relates to a scraping-type soil removal system for a vehicle's sediment removing device, which makes it possible to easily scrape accumulated sediment to the outside.

In general, a vehicle earth and sand removal device takes out earth and sand, mud, and other foreign substances adhering to the wheel of the vehicle and its vicinity when the construction vehicle leaves the site at a civil engineering site, a construction site, or the like. It is a device that cleans the wheels and body of the vehicle before leaving to prevent things from happening.

As a method of removing earth and sand and mud, there is also a method of removing earth and sand by passing through a puddle provided in a passage of a vehicle, but in the present invention, the wheels are idlely rotated on a roll provided in the passage to remove the earth and sand. It is applied to the shake-off method.

As described above, the earth and sand removing device of the vehicle is installed at the entrance and exit of the construction site, and when the vehicle leaves the site, it always passes through the device, shakes off the earth and sand, and then exits.

That is, when the vehicle rides on a pedestal provided in the earth and sand removing device of the vehicle and the tires are rotated, the earth and sand fall and the earth and sand accumulates below the gantry.

In this case, it is desirable to scrape out the accumulated earth and sand immediately after passing through the vehicle to clean it, but in reality, it is difficult to scrape out quickly because many vehicles come and go.

Even if a large amount of earth and sand is deposited and then taken out, the space under the gantry is as small as 10 to 20 cm, which makes it difficult to take out, and it takes a considerable amount of labor and time to remove all of it.

As a method of easily, quickly, and effortlessly removing the accumulated sediment, various methods such as laying a board under the device and pulling out the accumulated sediment, or providing a box and pulling it out are available on site. However, it is not easy to pull it out manually because the sediment containing a lot of water is heavy.

It is possible to increase the distance between the lower part of the gantry and the ground, but in this case it is necessary to raise the height of the entire device, in which case it is necessary to lengthen the uphill road of the vehicle, and the limited field space It is difficult within the range of.

When the amount of accumulated sediment becomes large in this way, the original function of the sediment removing device of the vehicle is impaired, and there is a problem that the function cannot be effectively exhibited.

The applicant of the present application has previously described in Patent Document 1 the front wheel mount and the rear wheel mount on which the front and rear wheels of the vehicle are mounted, the central slope connecting the front wheel mount and the rear wheel mount, and the rear wheel mount for the vehicle to enter. A pedestal main body including a continuous entrance side slope and an exit side slope connected to the front wheel pedestal, a front wheel drive roller and a rear wheel drive roller provided on the front wheel pedestal and the rear wheel pedestal, respectively, and a cleaning medium are stored. The front wheel drive roller is rotated in conjunction with the cleaning medium supply means for supplying the cleaning medium and the rotational force of the rear wheel drive roller due to the engine operation of the vehicle located on the rear wheel mount. , A rotation interlocking means for putting the pump of the cleaning medium supply means into an operating state, a cleaning medium supply pipeline provided on each of the front wheel pedestal and the rear wheel pedestal and having a nozzle communicated with the cleaning medium supply means, and the gantry. The front wheel mount, the front wheel of the vehicle on the rear wheel mount, which has a vehicle body cleaning medium injection unit having a nozzle that is arranged along the traveling direction of the vehicle with respect to the main body and communicates with the cleaning medium supply means. We have proposed a vehicle mud cleaning device configured to remove mud from the tires and the vehicle body of the vehicle by injecting a cleaning medium onto each tire of the rear wheel and the vehicle body.

With respect to the rotary screw body 7 adopting, for example, a trapezoidal screw, which is shaft-supported by the above and projected to the front side and the other end side is pivotally supported by the back side plate 3b, and the discharge-side side plate 3a of the scraping frame main body 2. The first and second drive frame portions 8a and 8b and the first and second drive frame portions 8a and 8b which are arranged in parallel in the front-rear direction and incorporate the lower portion of the side plate 3a on the discharge side so that earth and sand or the like can pass through. The ratio of the number of teeth to the driving sprocket 9 arranged in 8a and 8b and having one end of the rotary screw body 7 attached and the driving sprocket 9 distributed in the driving frame portions 8a and 8b is set to a plurality of stages (this embodiment). A plurality of sprocket groups, that is, three sprocket 12a, 12b, 12c in this embodiment, which are different from each other and have a mounting receiving portion 11 for a handle 10 for rotation operation at each protruding end. A handle for rotation operation that can be selectively mounted on the driving sprocket 9, the chain 13 hung on the three sprocket 12a, 12b, 12c and the mounting receiving portions 11 of the three sprocket 12a, 12b, 12c. 10 and a soil removal plate moving drive mechanism unit 14 including the above.

FIG. 6 shows the upper plate 4a, the lower plate 4b, and the hinge 5 constituting the soil removal plate 4 in the scraping type soil removal system 1 of this embodiment in a disassembled state.

FIG. 7 shows the configuration (horizontal plate 3c side) and operation of the earth and sand return avoidance mechanism unit 15 in the scraping type soil removal system 1 of this embodiment.

The earth and sand return avoidance mechanism portion 15 has a protrusion 16 projecting by a small size toward both lateral side plates 3c at one end of the lower plate 4b of the earth removal plate 4 on the horizontal plate 3c side, and the lateral side. A lower plate guide member 17 provided in a region of the side plate 3c facing the protrusion 16 is provided.

The lower plate guide member 17 includes a horizontal guide portion 18b and an inclined guide portion 18a that are attached to the lower portion of the inner wall of the horizontal side plate 3c so as to project from the inner wall of the horizontal side plate 3c toward the lower plate 4b having a small size. Is equipped with.

The earth and sand return avoidance mechanism portion extending over the other end portion of the horizontal side plate 3c and the horizontal side plate 3d is also configured in the same manner as described above.

Then, when moving to the back side (return side) of the soil removal plate 4, each lower plate guide member 17 is engaged with each protrusion 16 of the lower plate 4b, and the lower plate 4b is shown by an arrow in FIG. In this way, it is rotated upward to prevent the earth and sand below the lower plate 4b from returning to the back side, and to improve the efficiency of scraping out the earth and sand O.

Next, the measures for improving the moving speed of the soil removal plate 4 in the scraping type soil removal system 1 of this embodiment will be described.

In this embodiment, the three sprockets 12a, 12b, 12c arranged in the drive frame portions 8a, 8b have twice, three times, and four times as many teeth as the driving sprocket 9. It has a structure.
