Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sand sprinkling device which is used by being attached to a truck such as a dump truck when sprinkling sand for slip prevention in winter on a road with heavy snowfall.

[0002]

[Prior art]

 Conventionally, in snowy areas, spike tires have been installed on automobiles to prevent slippage in winter. However, spiked tires have a problem of dust pollution because they scrape off the road surface, and the spiked tire regulation law has greatly expanded the area covered by spiked tires in Hokkaido and other countries. Therefore, as an alternative to it, it was decided to install a studless tire, but the road surface polished by this studless tire undulates to a convex surface, while it becomes a slippery ice-burn state, and pedestrians as well as cars slip. The danger has probably arisen. In order to deal with this risk of slippage, a method of spraying burnt sand on the road surface by a truck is adopted. It was a type in which sand was sprinkled on the road surface by the rotation of a propeller that was filled and attached to the lower end of the box, and was attached to the rear end of the truck.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional sand spraying device, since the sand is sprayed by rotating the propeller, there is unevenness in the amount of sand that is sprayed, and since it is also sprayed in extra places, a large amount of sand is required, In addition, dust is easily generated during spraying, and sand is hit by ordinary vehicles, causing complaints. Also, since the power is the engine, noise during nighttime work could be a problem. Furthermore, it takes time to replenish the sand manually, and it was necessary to wear dust masks and glasses. This device was developed in view of the above circumstances.No noise or dust is generated during sand spraying, only the necessary part can be sprayed, the required amount of sand is reduced, and the replenishment of sand does not require human power. It is an object of the present invention to provide a sand spraying device that can contribute to resource saving, work efficiency improvement, noise problem improvement and work environment improvement by making it easy and smooth automatically.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is to attach to a truck such as a dump truck formed so that the loading platform can be tilted rearward, and has a width dimension substantially equal to the width dimension of the loading platform of the truck. It has a sand-like shape and is equipped with a sand supply port on the back that opens to the loading platform, and a horizontally elongated sand sprinkling port that occupies most of the width at the lower end. A sand spray valve is attached to each of the central parts, and each spray valve can be opened and closed.

【Example】

 Hereinafter, description will be given based on the illustrated embodiment. 1 shows a sand sprinkling device of the present invention. This sand sprinkling device 1 is used by being attached to a rear end portion of a truck A such as a dump truck formed so that a loading platform can be tilted rearward. It is formed in a box shape having a width dimension substantially equal to the width dimension of the loading platform of the truck A to be attached, and the sand filling portion 2 is formed in a horizontally long rectangular parallelepiped shape, and the lower portion thereof is squeezed to form an inverted triangular prism shape. The sand sprinkling section 3 is formed into a substantially inverted house shape.

Further, in the back surface portion of the sand filling portion 2 facing the loading platform of the truck A, there is provided a sand supply port 4 opening to the loading platform, and the back surface along the lower edge of the sand sprinkling unit 3 The laterally inclined surface 3a is provided with a horizontally long sand sprinkling port 5 that occupies most of the width dimension, and sprinkling valves 6, 6 and 7 for covering the sand sprinkling port 5 can be opened and closed via a hinge 8. It is installed.

The sand sprinkling valves 6 and 6 are attached to the left and right sides of the sand sprinkling port 5, and the sand sprinkling valve 7 is densely attached to the center of the sand sprinkling valve 7. Further, on the back side inclined surface 3a of the sand spraying part 3, two hydraulic cylinders 9 are attached in the vertical direction on the left side, two on the right side and one in the central part, and the sand spraying valves 6, 6, 7 are The hydraulic cylinders 9 are respectively connected to the corresponding hydraulic cylinders 9, and the hydraulic cylinders 9 at the required positions are expanded and contracted by the operation from the cab of the truck A. As a result, as shown in FIGS. , 6 and 7 are formed so as to open and close.

The opening and closing of the sand spray valves 6, 6, 7 will be described in more detail. When the hydraulic cylinder 9 is extended, the sand spray valve 6 (7) rotates in the closing direction, and when the hydraulic cylinder 9 is contracted, the sand spray valve 6 is closed. Reference numeral 6 (7) is formed so as to rotate in the opening direction, and is formed so that the size of the sand spray port 5 can be adjusted and the amount of sand sprayed can be adjusted. 4 to 6 show the open / closed state of the sand spray valve 6 (7). FIG. 4 shows the fully closed state, FIG. 5 shows the partially opened state, and FIG. 6 shows the fully opened state. Also, if only the sand spray valves 6, 6 on the left and right sides are opened, only the traveling part (the rudder part of the vehicle) can be sprayed (see Fig. 7), and by opening all spray valves 6, 6, 7 at the same time, It is possible to apply the entire surface required for such purposes (see FIG. 8).

Reference numeral 10 denotes a dust removing net. This dust removing net 10 is for removing dust mixed in the sand in advance, and the dust removing net 10 is horizontally and diagonally arranged in the middle portion of the sand filling portion 2. It is set up. The dust collecting net 10 is also attached to the loading platform of the truck A, and the closer to the sand sprinkler 5, the finer the mesh. The sand spraying apparatus 1 of the present invention having the above-mentioned structure is used by mounting it on the rear end of the loading platform of the truck A. In this case, remove only the trailing edge plate of the truck A cargo bed, and use the bolts 11 to attach the side wall 3b to the left and right flank boards B of the truck A so that the sand filling port 4 opens to the luggage carrier. Tighten and fix.

In use, when the sand is loaded on the loading platform of the truck A in advance and the sand is supplied to the sand spraying device 1, if the loading platform of the truck A is tilted backward, the loading is automatically performed. (See FIG. 9). On normal road surfaces other than intersections, open the sand spray valves 6, 6 on the left and right sides to spray sand only on the running part (see Fig. 7), and at intersections, etc., all sand spray valves 6, 6, 7 Open and spray all over (see Fig. 8).

[0011]

[Effect of device]

 As described above, in the sand sprinkling device of the present invention, the sand sprinkling valves attached to the sand sprinkling ports are separately attached to the left, right side and central portions, and are formed so that only the required sprinkling valves can be opened and closed. Therefore, on normal road surfaces other than intersections, only the required parts can be sprayed, such as by spraying only the running parts on the running part, and spraying the entire surface at the intersections.The amount of sand can be sprayed only by adjusting the opening degree of the spray valve. Can be used without waste. Moreover, since the spraying is of the drop type, it is quieter and quieter than the conventional rotary type, and it is difficult for dust to stand up.When replenishing sand, the bed of a truck such as a dump truck is tilted backwards. It can be automatically replenished simply and quickly, and does not require human power for replenishment, and therefore does not need to wear dust masks, glasses, etc. In addition, since the spray valve can be opened and closed by the hydraulic cylinder attached to each spray valve, the sand can be sprayed quietly and smoothly without noise by operating from the driver's seat. It is a device that can greatly contribute to the improvement of noise problems, work efficiency, and work environment.
