DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a spread material leveling apparatus according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the spreading and leveling device 7 is, for example, a device that is towed by being connected to the loading platform 8 side of a moving vehicle such as a truck or a dump truck. While slowly moving on the paved road surface E and slightly away from the end E1 of the road surface E, while moving the paving material 9 such as soil or sand to the side of the road surface E, Unpaved ground surface T such as a road shoulder
Spread on top. Therefore, this spreader 7 is shown in FIG.
As shown in FIG. 3, the litter 9 is placed, and the placed litter 9 is used as a lower opening 10 as an opening.
(See FIG. 3) A container 11 to be dropped is provided on the support S. Further, a plurality of wheels K are attached to the lower part of the support base S so as to be movable, and further, on the front side (see FIG. 2) in the moving direction of the spreading and leveling device 7 for pulling. The connector W is attached.

Further, the container 11 is provided with a loading port 12 on the upper side thereof, and a floor which is dropped from a loading platform 8 of a moving vehicle such as a truck loaded with the flooring material 9 through the loading port 12. Receive material 9. That is, the inlet 12 of the container 11 has an upper part that widens toward the loading platform 8 such as a truck, and the lower port 10 is lateral (in a direction orthogonal to the moving direction of the spreader 7). Because it has a narrow width extending, the lower mouth 1
A plurality of inclined surfaces 13 that incline toward 0 are formed. Therefore, the litter 9 falling from the loading platform 8 is
2 and then falls onto the inclined surface 13 and then the inclined surface 13
Glide over to the lower mouth 10. However, the opening is not necessarily limited to the lower opening 10, and may have a shape and position other than this, and the shape and the like of the container 11 are not limited to the above-described shape and the like, and other shapes and positions are possible. It may have a shape or the like.

On the lower side of the lower opening 10 of the container 11,
A screw conveyor 16 as a transfer device is arranged, and the screw conveyor 16 has a lower opening 10
The litter 9 that has fallen further downward is laterally disposed in a direction intersecting with the moving direction of the littering device 7 (for example, the orthogonal direction, but is not necessarily limited to the orthogonal direction). Transport. That is, the screw conveyor 16 is provided with a shaft 16a extending in the lateral direction and protruding to one side from the spreader 7, and a large number of blades 16b are provided on the outer periphery of the shaft 16a. Has been. The shaft 16a provided with the large number of blades 16b extends in the lateral direction, and
It becomes rotatable in the cylinder 16d via support mechanisms P1 and P2 provided at the left side end and the right side end of the cylinder 16d protruding to one side of the spreader 7. ing.

Therefore, when the shaft 16a of the screw conveyor 16 rotates in one direction, the blade 16b pushes the laying material 9 in the cylinder 16d toward the one side.
The shaft 16a is conveyed toward one side from the opposite side and drops downward from an opening 16e provided at one side end of the cylinder 16d. In this case, the reason why the screw conveyor 16 is used as the transport device is
This is because the litter 9 can be downsized as compared with the proportion of the amount of the litter 9 transported, and the litter 9 can be transported to the outside of the cylinder 16d without leaking. However, the shape and structure of the screw conveyor 16 are not necessarily limited to those described above,
The shape and structure may be other than this, and a conveyor other than the screw conveyor 16 may be adopted as the conveying device, and other conveying means may be adopted.

At this time, it is preferable that one side end of the cylinder 16d is largely projected to one side of the spreader 7. This is because the opening 16e provided at one side end of the cylinder 16d largely protrudes to one side so that a truck or the like on which the flooring 9 is placed on the cargo bed 8 or the like is an end of the paved road surface E. Since it is not necessary to move the tire closer to the part, and the load of the tire supporting the weight of the truck is not applied to the end of the paved road surface E, a crack or the like is generated at the end of the paved road surface E. This can prevent this.

A drive device 18 for driving the screw conveyor 16 is provided at the rear side of the container 11.
It is provided on the support S. The drive device 18 includes an engine unit 19, a speed reduction unit 20, and a transmission unit 21. The engine unit 19 includes a rotating shaft 19a, and the driving of the engine unit 19 can rotate the rotating shaft 19a in one direction. And the engine section 19
When the rotating shaft 19a is rotated in one direction by driving the rotating shaft 19a, the rotation of the rotating shaft 19a is transmitted through the belt 19b covered by the cover C1 to the input shaft 20a of the speed reducer 20.
And the rotational speed thereof is reduced in the speed reducer 20.

As shown in FIGS. 2 to 4, the transmission portion 21
Is composed of a belt 21a for connecting the pulley 20c attached to the output shaft 20b of the speed reducer 20 and the pulley 16f attached to the shaft 16a of the screw conveyor 16, and the rotation of the output shaft 20b of the speed reducer 20 is It is transmitted to the shaft 16a of the screw conveyor 16 via the belt 21a and the like covered with the cover body C2. As a result, the engine unit 1 is passed through the reduction unit 20 and the transmission unit 21.
Shaft 1 of screw conveyor 16 to which drive 9 is transmitted
6a rotates in one direction, and as described above, the laying material 9 in the cylinder 16d is pushed by the blades 16b while the shaft 1
6a is conveyed from the opposite side toward the opening 16e on the one side.

A leveling member 23 for leveling on the ground surface T is provided on the side of the screw conveyor 16, and the leveling member 23 is conveyed to the side by the screw conveyor 16 and is fed to the screw conveyor 16. Cylinder 16d
The flooring material 9 that has fallen through the opening 16e on the side of is ground on the ground surface T. Further, the leveling member 23 includes a support member 24 extending to the side, and the leveling blade 25 is attached to the support member 24. That is, as shown in FIG. 5, the support member 24 is made of a plate material such as a metal plate having an L shape including a long arm portion 24a and a short arm portion 24b, while the leveling blade 25 is provided. Is, for example,
A flexible elastic material such as a rubber material is used as a material, and the long arm portion 24a and the short arm portion 24 of the support member 24 are used.
It is attached to the support member 24 so as to be bent in a U shape along both sides of b and to hang down in the direction of the ground surface T.

The tips of the plurality of bolts B attached so as to penetrate the upper part of the leveling blade 25 are provided in the long arm portion 24a and the short arm portion 24b of the support member 24 in the vertical direction. It penetrates each of the plurality of elongated holes 24c extending in the direction of and is fastened by a nut N. For this reason, the upper portion of the leveling blade 25 has a bolt B and a nut N.
The lower portion of the leveling blade 25, which is firmly fixed by the above, but which hangs down in the direction of the ground surface T, is a flexible free end portion. Therefore, for example, a part of the laying material 9 that has fallen on the ground surface T and is piled up in a mountain shape, or an obstacle such as a large lump of stone on the ground surface T is laid on the laying device 7.
Since the lower part of the leveling blade 25 is elastically deformed by pushing the lower part of the leveling blade 25 at the time of moving, the lower part of the elastically deformed leveling blade 25 bends freely, and a part of the litter 9 is Or, an obstacle or the like on the ground surface T can be escaped to the rear side.

The elongated holes 24c extending in the vertical direction are formed to adjust the height of the leveling blade 25 with respect to the ground surface T, and are attached so as to penetrate the leveling blade 25. When the tip portion of the bolt B of No. 2 is slid vertically in the long hole 24c and is tightened and fixed by the nut N, the lower portion of the leveling blade 25 is separated from the ground surface T, or Since they are located close to each other, the litter 9 can be leveled with the required height with respect to the ground surface T according to the surrounding environment such as a work site and the working situation. Therefore, the support member 24
Although the long hole 24c and the bolt B provided in the function as a height adjusting mechanism for adjusting the height of the leveling blade 25,
The height adjusting mechanism may include a height adjusting mechanism other than the above structure. The support member 24 is provided with a leveling blade 2 according to the surrounding environment, the working situation, and the like.
Adjusting the height of 5 is desirable in terms of work efficiency,
This height adjusting mechanism does not necessarily have to be adopted depending on the surrounding environment, working conditions, and the like. Further, the leveling member 23 is not necessarily the support member 24 and the leveling blade 2.
However, the support member 24 and the leveling blade 25 may have an integral structure, for example.

Further, in this embodiment, one end of the L-shaped long arm portion 24a has a shaft portion 27a (see FIG. 3) of a hinge mechanism 27 provided at a side rear portion of the cylinder 16d of the screw conveyor 16. ) Is used as a rotation center, and it is rotatably attached between a position Q1 that extends laterally and a position Q2 that is close to the rear portion of the cylinder 16d. This is because when the spreading and leveling device 7 is moved or stored, the support member 24
At the position Q2 closer to the rear part of the cylinder 16d,
This is because it does not hinder the movement or requires a small storage space.

Specifically, through holes (not shown) opened in the vertical direction are provided at positions where the upper support plate 27b and the lower support plate 27c of the hinge mechanism 27 face each other, and these through holes are provided. Has a cylindrical portion Z (see FIG. 4) integrally formed at one end of the long arm portion 24a, and both ends of a shaft portion 27a are rotatably fitted therein. Also, the long arm 2
As shown in FIG. 5, the long arm portion 24 is provided at the upper end of 4a.
An L-shaped plate 24d extending along a is provided, and a plurality of holes 24e are formed in the L-shaped plate 24d along the longitudinal direction of the long arm portion 24a, while the hinge mechanism 27 is used.
A fixing pin 28 is provided on the upper support plate 27b so as to be removable upward and extend laterally. The one-side bent portion 28a formed by bending the fixing pin 28 downward is formed into the plurality of holes 2 of the L-shaped plate 24d.
The support member 24 is rotatable between the position Q1 and the position Q2 by being removed above one in 4e, while the one-side bent portion 28a of the fixing pin 28 is rotated.
However, the support member 24 is fixed by being fitted into one of the plurality of holes 24e of the L-shaped plate 24d.

The support member 24 extends laterally so as to incline at a predetermined opening angle D (see FIG. 3), which opens rearward from the direction orthogonal to the moving direction. Specifically, the length of the longitudinal portion 28b of the fixing pin 28 is determined by the position of the shaft portion 27a of the hinge mechanism 27 and the hole 2 of the L-shaped plate 24d.
It is a little shorter than the distance to the position of 4e,
Further, since the opposite side bent portion 28c of the fixing pin 28 is rotatably fitted into the hole Q opened in the upper support plate 27b of the hinge mechanism 27, the fixing pin 28 is bent on one side. When the portion 28a is fitted in one of the plurality of holes 24e of the L-shaped plate 24d and the support member 24 is fixed, the support member 24 is located rearward of the direction orthogonal to the moving direction. Lean to the side. The reason why the support member 24 forms such a predetermined opening angle D is that a part of the laying material 9 piled up on the ground surface T or the ground surface T, such as a stone block, is present. This is for allowing obstacles and the like to escape to the side of the support member 24 (the left side of the paper surface of FIG. 3).

The reason why the L-shaped plate 24d is provided with a plurality of holes 24e along the long arm 24a is that the size of the opening angle D is adjusted according to the environment around the ground surface T and the like. This is because Therefore, the operator selects one of the plurality of holes 24c of the L-shaped plate 24d according to the environment around the ground surface T, and the one-side bent portion 28a of the pin 28 for fixing to the selected hole 24e. Can be adjusted to an appropriate opening angle D. The reason for adjusting the size of the opening angle D is
It is possible to adjust a part of the litter 9 piled up on the ground surface T or the amount of obstacles such as stone blocks that are on the ground surface T to escape, and This is because the length of the spread width T1 (see FIG. 3) extending in the direction orthogonal to the moving direction can be adjusted when the spread member 23 is spread. Therefore, the plurality of holes 24c and the one-side bent portion 28a of the fixing pin 28 are formed.
Serves as an opening angle adjusting mechanism that adjusts the size of the opening angle D of the support member 24. However, the configuration of the opening angle adjusting mechanism is not necessarily limited to the above-mentioned configuration, and a structure other than the above-described structure is used. May be adopted. Also, the support member 2
It is not always necessary to adopt a structure for adjusting the size of the opening angle D that opens to the rear side of 4, but it is preferable to have a structure for adjusting the size of this opening angle according to the surrounding environment and the like. .

Next, a method of using the spreader 7 for spreading the spreader 9 will be described.

The connecting tool (not shown) and the connecting tool W of the spreader 7 are connected by a metal fitting Z for traction (see FIG. 1). After that, as a preparatory work, the operator slides the tip end portions of the plurality of bolts B attached so as to penetrate the leveling blade 25 in the elongated hole 24c in the vertical direction,
By tightening with the nut N, the height of the leveling blade 25 is adjusted with respect to the ground surface T, and the plurality of holes 24 of the L-shaped plate 24d are adjusted according to the environment around the ground surface T.
One in c is selected, the one side bent portion 28a of the fixing pin 28 is fitted into the selected hole 24e, and the size of the opening angle D of the support member 24 is adjusted.

Then, the front side of the loading platform 8 is slightly raised, and the loading platform 8 is tilted so as to have a slight downward slope toward the spreading and leveling device 7, and the laying material 9 on the loading platform 8 is placed in the container 11 thereof.
Throw in. Then, the covering material 9 dropped from the loading platform 8
Slips along the inclined surface 13 of the container 11 and moves from the lower port 10 of the container 11 to the blade 16b of the screw conveyor 16.
As it falls onto the container 11 and the like, the necessary amount of the litter 9 is put into the container 11. Then, the opening 16e on the side of the cylinder 16d of the screw conveyor 16 and the leveling member 23 are positioned on the unpaved ground surface T on the side of the road surface E.

When the preparatory work is completed, the worker
When a moving vehicle such as a truck is slowly moved on the paved road surface E, the spreader 7 is also paved on the paved road surface E.
Move slowly over. Then, when the driving device 18 is driven, the flooring material 9 is conveyed to the side by the blades 16b of the screw conveyor 16, and the ground surface T passes through the opening 16e at the side of the cylinder 16d of the screw conveyor 16.
Fall to the top. Then, the leveling member 23 is laid out and leveled by the leveling device 7
By moving integrally with the lower part of the leveling blade 25, the laying material 9 can be leveled uniformly on the ground surface T.

In this case, while the main body of the spreading and leveling device 7 moves on the paved road surface E, soil, sand, etc., on the ground surface T on the side of the road surface E, such as the shoulder of the road surface E, can be used. Floor covering 9
Since the paved road surface E does not have much spread material 9, the dirt on the paved road surface E is reduced,
The labor of cleaning the road surface E after the spreading and leveling work is reduced.
And so that the bedding material 9 in the container 11 is not lost,
When moving the spreading and leveling device 7, the front side of the loading platform 8 is raised little by little, and the loading platform 8 is inclined so that the downward slope toward the spreading and leveling device 7 is gradually increased, and the loading on the loading platform 8 is increased. If the material 9 is continuously put into the container 11, the flooring material 9 can be continuously leveled on the ground surface T.

The present invention is not limited to the above-mentioned embodiments, but various modifications can be made. For example, the litter 9 may be made of a litter 9 other than soil, sand, aggregate, or the like, and the litter 9 such as soil, sand, or aggregate.
Does not necessarily need to be laid evenly on the ground surface T such as a road shoulder or a slope, for example, a restoration work site for excavated pipe work, a work site for making a sidewalk, or a median strip. It may be laid evenly on the ground surface other than that, such as the work surface of the work site for making the. Further, the spreading and leveling device 7 may be downsized so that the work can be performed even on a narrow road, or it may be changed to a self-propelled type. Alternatively, the spreading and leveling device 7 for the plurality of spreading materials 9 may be pulled by one truck. In addition, this spreader 7
May be provided with a charging device for automatically charging the litter 9 into the container 11, or may be provided with an adjusting device for adjusting the amount of fall of the litter 9.
