Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to an earth and sand loading device for scooping up earth and sand accumulated on the roadside.

(Prior Art) During the winter, asphalt debris from the road surface scraped off by tire chains and the like is mixed with sand and dust, and is pushed to the roadside along with snow, where it hardens and accumulates. As a device for removing such accumulated earth and sand, a road cleaning vehicle that uses a rotating brush to suck up earth and sand and feed it into a nozzle is disclosed in, for example, Japanese Utility Model Publication No. 57-36368. However, in road sweeping vehicles, the rotating brushes are weak and cannot break up accumulated dirt, and a large amount of dirt cannot be processed in a relatively short period of time.

As a solution to these problems, Japanese Patent Application Laid-Open No. 62-25628 discloses a sand scrape-up plow in which a pair of left and right sand plows is provided to scrape up dirt, etc. that has accumulated on the roadside as the vehicle advances. . In this earth and sand scrape-up plow, the earth and sand plow can be moved to follow the road surface to efficiently scrape up earth and sand. equipment was requested.

And as a device to load the raked earth and sand,
A groove cleaning head with a conveyor structure that can freely rotate laterally with respect to the direction of movement of the truck is provided, and this groove cleaning head is constructed by connecting a plurality of scrapers into an endless chain, and a screw is installed in front of the groove cleaning head. A power auger equipped with a power auger is installed, and the power auger loosens the mud and earth accumulated in roadside ditches into small pieces. After being collected by multiple scrapers that slide along the groove cleaning head, it is transported to a bucket lifting device connected to the top of the groove cleaning head, and then transported via a conveyor belt installed on the top of the car body by the bucket lifting device. Japanese Patent Publication No. 59-9686 discloses a groove cleaning device that discharges dust into a dust container at the rear of the vehicle body.

(Problems to be Solved by the Invention) The ditch cleaning device has a ditch cleaning head installed horizontally with respect to the traveling direction of the vehicle, and a bucket truck that discharges the dirt collected by the ditch cleaning head into a dust container at the rear of the vehicle. Since the elevating device and conveyor belt are installed sideways with respect to the direction of vehicle movement so as to be connected to the gutter cleaning head, the widthwise dimension of the work vehicle including the gutter cleaning head, bucket elevating device, conveyor belt, etc. increases. When removing earth and sand, the ditch cleaning head is laid down and protrudes greatly from the side of the vehicle, so the width dimension becomes even larger due to the turning space.As a result, during the earth and sand removal work, The space occupied by the work vehicle in the width direction on the road increases. Furthermore, the leading screw-type power auger is first rotated in a direction perpendicular to the direction of vehicle travel to loosen the hardened soil into small pieces, and the loosened soil is transferred to the ditch cleaning head. Since multiple scraping plates inside the bucket are used to raise the bucket up and down, dust is scattered laterally when scraped by a power auger, which not only causes dust pollution, but also makes it difficult to collect the scattered dust. Not only is it difficult to remove soil and sand efficiently, but also the scraping plate that scrapes up the soil loosened by the power auger slides directly into hard grooves such as concrete, and the rotation of the endless scraping chain causes damage to the road. As the scraper rotates along the Removal of the scraper plate requires complicated work, and there is a problem of poor maintainability.

This invention was developed to solve these problems, and it is a dirt removal system that can efficiently scrape up dirt and sand accumulated on the roadside as the vehicle moves along, and also allows for easy replacement of consumables. The present invention provides a loading device.

[Structure of the invention] (Means for solving the problem) A drive wheel is suspended between a driving wheel and a driven wheel provided on a frame, and is installed obliquely backward with respect to the direction of travel of the vehicle, almost along the side of the vehicle. an annular band, a guide plate attached below the annular band substantially parallel to the annular band and having an elastic plate at its lower end capable of slidingly contacting the road surface; The vehicle is provided with a raking plate that protrudes from the outer surface at intervals and that rakes up earth and sand on the road surface along the guide plate by rotation of the drive wheel.

(Function) When the annular band rotates, the raking plates protruding from the annular band on the leading side catch dirt on the road surface and scoop it up along the guide plate. The earth and sand on the road surface can be scraped off with the elastic plate, and the earth and sand can be scraped up along the guide plate with the raking plate.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

1 and 2 show the first embodiment,
Reference numeral 1 denotes a self-propelled tractor type vehicle, and an earth and sand plow 3 is attached to the front part of the tractor type vehicle 1 via a mounting arm 2 so as to follow a road surface A.

Reference numeral 4 denotes a frame connected to the rear part of the tractor-type vehicle 1 via a link mechanism 5 and having an open bottom surface. Reference numeral 6 denotes an endless conveyor diagonally installed on the frame 4 with its lower end approaching the road surface A and facing diagonally rearward and upward. A driving wheel 8 such as a sprocket is pivotally attached to the upper end of the frame 7, and a driven wheel 9 such as a sprocket is provided close to the road surface A at the lower end of the frame 7. Guide wheels 10 such as the like are arranged in the longitudinal direction. An annular band 11 is suspended between the driving wheel 8 and the driven wheel 9, and scraping plates 12 are disposed horizontally on the surface of the annular band 11 at intervals in the longitudinal direction of the annular band 11. Further, this scraping plate 12 is provided so as to protrude from the annular band 11 so as to form a slight gap between its tip and the ground A.
13 is a guide plate 13 provided below the endless conveyor 6 and parallel to the endless conveyor 6 with a gap therebetween.
A rubber plate portion 14, which is an elastic plate that slides on the road surface A, is provided at the lower end, and the upper end of the guide plate 13 is provided slightly below the drive wheel 8.

15 is a hydraulic or electric motor that rotates the drive wheel 8 in a counterclockwise direction. That is, the annular band 11 is rotated by the motor 15 so that the scraping plate 12 facing the guide plate 13 is raised. Reference numeral 16 denotes a hopper provided below the upper end of the guide plate 13. A starting end 17A of a belt conveyor 17 is connected to this hopper 16, and a terminal end 17B of the belt conveyor 17 is connected to a dump truck 18.
installed on the loading platform. The belt conveyor 17
is obliquely installed on a frame 20 on which a wheel 19 is mounted,
Further, a removable traction rod 21 is connected between the tractor type vehicle 1 and the dump truck 18.

Next, the operation of the above structure will be explained.

When the tractor-type vehicle 1 runs along the roadside,
The belt conveyor 17 and dump truck 18 are also towed and run. The earth and sand B on the roadside is crushed by the earth and sand plow 3 and successively collected in the center of the tractor-type vehicle 1. When the soil B thus collected is located at the lower end of the endless conveyor 6, it is successively scraped up along the guide plate 13 by the scraping plate 12. In this case, the plurality of raking plates 12 protruding from the annular band 11 bite the earth and sand on the road surface A and guide it toward the guide plate 13, but the raking plates 12
does not come into direct contact with the road surface A, but scrapes up only the dirt B with a small gap between the road surface A and the road surface A. Scrape off the earth and sand B by sliding it in contact with the earth.

The earth and sand B falling into the hopper 16 from the upper end of the guide plate 13 is sent to the dump truck 18 by the belt conveyor 17. When dump truck 18 is fully loaded with earth and sand B, tractor type vehicle 1
The driver stops the truck, removes the towing rod 21, connects the empty dump truck 18 again, and starts traveling. Incidentally, if the earth and sand B is not to be scooped up, the frame 4 is lifted slightly upward by the link mechanism 5.

As described above, the frame 4 is attached to the rear of the tractor-type vehicle 1, and the annular band 11 having the scraping plate 12 whose lower end forms a gap with the road surface A is attached to the side of the tractor-type vehicle 1. By installing the frames 4 diagonally so that they are parallel to each other, only the installation space for the width of the annular band 11 is required on the side of the tractor-type vehicle 1, which reduces traffic congestion during work. There is little adverse effect, and furthermore, by placing the guide plate 13 parallel to the lower part of the annular band 11 and slidingly contacting the rubber plate part 14 provided at the lower end with the road surface A, the earth and sand B is moved by the rubber plate part 14 to the road surface. It is directly raked up from A and can remove dirt B without leaving it on the road surface A. In particular, by providing the motor 15 so that the raking plate 12 facing the guide plate 13 is raised, the earth and sand B can be directly scraped up along the guide plate 13 from the road surface A. Therefore, compared to the case where the annular belt 11 is rotated in the opposite direction, the soil B can be scraped up without spilling the earth and sand B from the road surface A at the beginning of scraping up. In addition, the scraping board 12
By forming a gap between the road surface A and the road surface A,
Since the scraping plate 12 and the road surface A do not come into direct contact, the scraping plate 12 is prevented from being worn out, and the rubber plate part 14, which is a consumable item that comes into direct contact with the road surface A and is easily worn out, is minimized. This makes it easy to replace the rubber plate portion 14. Furthermore, when the annular band 11 rotates to guide the earth and sand B on the road surface A to the guide plate 13, the preceding raking plate 12 bites into the earth and sand B on the road surface A. At the same time, the dirt B on the road surface A is scraped off with the rubber plate part 14 on the rear side in the direction of vehicle movement, and the dirt B is scraped up along the guide plate 12 by the scraping plate. From scraping up
When scraping the earth and sand B, the scraped earth and sand B does not turn into dust and scatter, and moreover, the annular zone 1
1 and the guide plate 13 are inclined backward with respect to the traveling direction of the tractor-type vehicle 1.
The earth and sand B removed by the lined rubber plate part 14 is transferred to the guide plate 13
can be scraped up efficiently along the slope.

Further, a hopper 16 is provided below the upper end of the guide plate 13, and the terminal end 17B is connected to the dump truck 18.
By connecting the starting end 17A of the belt conveyor 17 provided at the hopper 16 to the hopper 16, the raked up earth and sand B can be sent to the dump truck 18, and the earth and sand B on the road surface A can be continuously removed.

Moreover, by providing the rubber plate part 14 at the lower end of the guide plate 13 and grounding it, it is possible to completely prevent the earth and sand B from escaping.
