Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leveling machine such as an asphalt finisher for spreading a pavement material such as asphalt mixture on a road surface.

[0002]

2. Description of the Related Art Conventionally, a generally known asphalt finisher is provided with a dump truck on the front side, and while the self-propelled vehicle of the asphalt finisher pushes this dump truck forward, it runs continuously with the dump truck, The pavement material input from the truck is received by a hopper, the pavement material received by the hopper is conveyed backward by a predetermined amount by a feeder, and the conveyed pavement material is spread left and right on the road surface by a screw. Are spread from above by screeds.

[0003]

However, the above-described conventional flattening machine has a basic structure in which the vehicle travels while pushing the dump truck on the front side and running in parallel with the dump truck. Due to the long time, there was a problem that the rotation rate (use efficiency) of the dump truck was deteriorated.

[0004] In order to deal with such a problem, a flattening machine called a smooth paver, mainly in Europe and the United States, has been developed. This smooth paver has basically the same configuration as the above-mentioned asphalt finisher, but differs in that it has a large storage hopper (having a capacity equal to or more than one dump truck). That is, the large storage hopper is characterized in that all the paving materials transported by the dump truck are loaded, and the paving work is continuously performed for a long time while the loaded paving materials are gradually fed out. According to this smooth paver, the time for running alongside the dump truck is short, and the rotation rate of the dump truck is increased. In addition, by loading a large amount of pavement material, there is almost no waiting time for the dump truck, and there is an advantage that smooth pavement can be performed without interrupting construction.

[0005] However, the above-mentioned smooth pavers cannot be said to be perfect devices, and have the following problems. That is, in loading the paving material into the storage hopper, since the storage hopper itself is large, the height of the upper opening of the storage hopper is relatively high, and the paving material cannot be loaded directly from the dump truck into the storage hopper. Had to use a dedicated self-propelled loading machine. For this reason, there was no problem when using an asphalt finisher.A new problem, that is, the need for a dedicated self-propelled loader increased the cost, or was required to operate a self-propelled loader. In addition, there is an economic problem such that labor is required and labor costs are increased.

[0006] The present invention has been made in view of the above circumstances, it is possible to supply pavement material without running alongside a dump truck or the like, and to dump without using a dedicated self-propelled loading machine. An object of the present invention is to provide a leveling machine capable of loading a pavement material from a truck or the like.

[0007]

According to a first aspect of the present invention, there is provided a leveling machine according to the first aspect of the present invention, in which a hopper for storing pavement material and a pavement material discharged from the hopper are provided to a self-propelled vehicle. A paving material distributing device that spreads left and right on a road surface, and a spreading device that is provided with a spreading device that spreads the paving material spread on the road surface, wherein the self-propelled vehicle includes: And a loading feeder for charging a pavement material into the hopper is provided.

In the above means, the hopper for storing the paving material is provided in the self-propelled vehicle, so that the hopper capacity can be freely set to a large value. For example, the paving material conveyed by a dump truck or the like can be used. All can be loaded on the hopper. That is, the above-described smooth-spacing use is possible. In addition, when loading paving material such as a dump truck into the hopper, a loading feeder provided in advance in the self-propelled vehicle is used, so that a self-propelled loading machine conventionally used when using a smooth paver is unnecessary.

In the flattening machine, at least one of the hoppers for storing paving materials may be set to have a larger capacity than the loading capacity of the truck for transporting paving materials. In this case, the load of the pavement material transport truck can be transferred to one hopper as it is, and the work efficiency is improved.

There is provided only one loading feeder extending from the receiving hopper at the front end of the self-propelled vehicle to the center in the left-right direction, and the front hopper and the rear are located below the middle portion in the front-rear direction and the rear end of the loading feeder. A side hopper may be provided, and the loading feeder may be provided with switching means for switching whether the pavement material conveyed by the loading feeder is to be fed to the front hopper or the rear hopper. in this case,
Since the pavement material can be supplied to the front and rear hoppers by one loading feeder, the number of components and the space for arranging components can be reduced.

A dispensing feeder is provided so as to extend from the lower end of the front hopper to the paving material discharging means, and the paving material discharging means is arranged below the rear hopper so as to face the lower end opening of the rear hopper. (Claim 4). In this case, the paving material discharged from the front hopper is conveyed by the feeder, but the paving material discharged from the rear hopper is directly supplied to the paving material discharging means without using a feeder or the like. That is, by arranging the paving material discharging means below the lower end opening of the rear hopper, the paving material discharged from the rear hopper can be directly supplied to the paving material discharging means without using a feeder.

[0012] Engines may be provided on the left and right sides of the loading feeder of the self-propelled vehicle, respectively.
In this case, since the engines are arranged in the empty spaces on the left and right sides of the loading feeder, the space can be effectively used, and the entire flattening machine can be made compact.

The loading device A mainly includes a loading feeder 16 and a receiving hopper 17. The loading feeder 16 is disposed so as to extend rearward and upward from the receiving hopper 17, and has rotating shafts provided at one end (lower end) 19 a (FIG. 5) and the other end (discharge end) 19 b of the loading frame 19. 2
A drive motor 27 (see FIG. 4) connected to a rotating shaft 21 is formed by stretching endless chains 25, 25 having a large number of flights 24 laid at predetermined intervals on sprockets 22, 22, 23, 23, respectively. ), The endless chain 25 is rotated, and the pavement materials Ha, Hb can be transported by the flight 24 from the lower end 19a of the loading frame 19 to the discharge end 19b disposed directly above the rear hopper 3. It has become.

The loading feeder 16 includes a lifting cylinder 28.
The pivot 29 is moved up and down by the operation of FIG.
The pivot 29 is attached to a movable shaft 32 that is movably inserted in the fixed cylinder 31 in the front-rear and left-right directions (FIGS. 3 and 5). Therefore, the loading feeder 16 is freely movable back and forth and rotatable left and right in the moving range of the movable shaft 32 with respect to the mobile vehicle 1 to which the fixed cylinder 31 is fixed. Note that the front plate 3a (FIG. 1) of the rear hopper 3 is configured to fall forward with the hinge as a fulcrum when the loading feeder 16 falls down.

The lower end 19a of the loading frame 19 and the discharge end 1
9b in the middle part, specifically, just above the front hopper 2.
The two outlets 19c and 19d (FIG. 5)
Are formed so as to be displaced in the longitudinal direction, and are respectively opened and closed individually by the rotation of the opening / closing lid 35 about the mounting shaft 36 by the opening / closing cylinder 34. That is,
The opening / closing cylinder 34 and the opening / closing lid 35 constitute a switching means for switching whether the pavement material conveyed by the loading feeder 16 is supplied to the front hopper 2 or the rear hopper 3. Narrow bands 37 (FIG. 6) are attached to both sides of the outlets 19c and 19d, which are separated from the flight path, to prevent the opening / closing lid 35 from rotating excessively upward.

A stop member 40 is attached to the lower surface of the loading frame 19 to stop the retraction of the loading feeder 16 by coming into contact with a contact member 39 (FIG. 3) having a bolt structure. The contact member 39 is adjustably screwed to a nut member 41 fixed to the vehicle 1.

The receiving hopper 17 is supported via a ball bearing 44 on a cylindrical portion 43 of each of the widened portions 19e (FIGS. 7 and 9) connected to the left and right ends of the lower end 19a of the loading frame 19, and a pair of left and right sides is provided. The rotary cylinder 45 can be turned up and down. Each widening portion 19e is provided with a scraping screw 47 connected to the rotating shaft 20. Each scraping screw 47 rotates together with the rotating shaft 20 by the driving force of the hydraulic motor 43a to scrape the pavement material in the widened portion 19e toward the endless chain 25.

The front hopper 2 and the rear hopper 3
Is preferably set to a value larger than the loading capacity of the dump truck T, but at least the total capacity of both hoppers 2 and 3 is sufficiently larger than the loading capacity of the dump truck T. Is set to a value.

Reference numeral 49 denotes an auxiliary hopper, which is attached to the left and right sides of the receiving hopper 17 by a support shaft 50 so as to be rotatable up and down. The two auxiliary hoppers 49 allow the paving material to be received from the wide dump truck T (FIG. 3), and can be folded on the receiving hopper 17 by the pair of left and right folding cylinders 51. Have been.

A pair of left and right support wheels 53 are provided on the lower surface of the base 17a (FIG. 3) of the receiving hopper 17, and a pair of right and left pressing members 54 of a roller structure are moved forward and backward by a guide shaft 55 at the front. It is provided freely. Support wheel 53
Supports the load of the receiving hopper 17 and the auxiliary hopper 49, and the pressing member 54 presses the rear wheel of the dump truck T in a well-known manner. ing. It is preferable that the guide shafts 55 and 55 and the front and rear cylinders 56 are disposed in the same plane, since no moment is generated by the operation of the front and rear cylinders 56.

As shown in FIG. 2, the loading feeder 16 is provided at the center in the left-right direction of the vehicle 1 so as to extend from the front end to the vicinity of the rear end of the vehicle 1. Hydraulic pumps 61 and 62 are provided on the left and right sides of the loading feeder 16 at the front of the self-propelled vehicle, and an engine (not shown in the drawing) is provided on the shafts of the hydraulic pumps 61 and 62 via couplings. ) Is installed. The hydraulic pumps 61 and 62 serve as driving sources for various devices such as a hydraulic motor that drives the self-propelled vehicle 1 via the crawlers 11 and 12 and cylinders.

Next, the operation of the flattening machine configured as described above will be described. The solid line in FIG. 1 shows the receiving state of the pavement material, and each auxiliary hopper 49 is tilted substantially horizontally beside the receiving hopper 17 supported by the support wheel 53,
The loading feeder 16 is arranged obliquely. In this state, the paving material is put into the receiving hopper 17 and the auxiliary hoppers 49, 49 from the dump truck T while pushing the dump truck T with the pressing member 54 and moving forward with the self-propelled vehicle 1. At this time, if the inclination angle of the loading frame 19 changes due to unevenness of the road surface or the like, the loading feeder 16 is guided by the fixed cylinder 31 and freely moves back and forth, left and right according to the change, and moves with respect to the contact member 39. The stop member 40 is kept in contact. Therefore, no excessive force is applied to the pivot 29.

Here, since the total capacity of the front hopper 2 and the rear hopper 3 is set to a value sufficiently larger than at least the loading capacity of the dump truck T, the dump truck T
All the cargoes of the receiving hopper 1
It can be transferred to the hoppers 2 and 3 via the loading feeder 7 and the loading feeder 16. After that, the dump truck is separated, and the paving work can be performed by the leveling machine alone. This means that the rotation rate is improved when viewed from the dump truck side, and at the same time, when viewed from the flattening machine side, there is almost no waiting time of the dump truck T, and smooth construction with little interruption can be performed.

When, for example, ordinary paving material Ha put in the receiving hopper 17 and the auxiliary hoppers 49, 49 is put in the front hopper 2, the opening / closing lid 35 is moved by the opening / closing cylinder 34 to the two-dot chain line in FIG. , The discharge ports 19c and 19d are opened respectively, and the loading feeder 16 is opened.
By driving the drive motor 27, the endless chain 25 is rotated, and the paving material Ha is carried by the flight 24 and dropped into the front hopper 2 from the discharge ports 19c and 19d.
Since the outlets 19c and 19d are provided so as to be shifted in front and rear, two peaks of the pavement material are formed adjacent to each other due to the drop of the pavement material. Therefore, the sum of the apex angles of a plurality of peaks is larger than that of a mountain that can be formed only by one peak, and a large amount of pavement material can be put in the front hopper 2 accordingly.

Further, for example, a pavement material H having high wear resistance is used.
b is inserted into the rear hopper 3, the outlets 19c, 1
9d is closed with the opening / closing lid 35 (see the solid line in FIG. 6), and the paving material Hb in the receiving hopper 17 and the auxiliary hoppers 49, 49 is carried by the flight 24 to the discharge end 19b and dropped into the rear hopper 3.

In the above, the scraping screw 47 is rotated by the rotating shaft 20 of the loading feeder 16 and the widened portion 19 is rotated.
The pavement material of (e) is scraped to the flight 24 portion. For this reason, the pavement material is efficiently transported to the front hopper 2 and the rear hopper 3, and the amount of the pavement material remaining in the receiving hopper 17 is reduced. When the amount of the paving material in the auxiliary hopper 49 becomes small, the auxiliary hopper 49 is inclined by the folding cylinder 51 to promote the drop of the paving material to the widened portion 19e.

The paving material Ha of the front hopper 2 is sent by the bar feeder 4 to the front of the front spreading screw 5, and is spread laterally by the spreading screw 5 to form the front screed 8.
Spread with. Further, the paving material Hb of the rear hopper 3 is dropped from the dropping hole of the rear hopper 3 onto the rear spreading screw 7, spread laterally with the spreading screw 7, and paved with the paving material Ha with the rear screed 9. Spread over the top.

When the flattening machine is sent to another pavement site or the like, each auxiliary hopper 49 is folded on the receiving hopper 17 by the folding cylinder 51, and the receiving hopper 17 is rotated by the rotating cylinder 45 to load the loader 16 into the loading feeder 16. The loading feeder 16 is caused to fall down substantially horizontally by the raising / lowering cylinder 28 while being turned to the side (see the two-dot chain line in FIG. 1). This shortens the overall length of the leveling machine and reduces its height. The cylinders 28, 34, 45, 51, 56 are usually hydraulic cylinders, but air cylinders can also be used. The drive motors 27 and 43a are hydraulic motors or electric motors.

In the above embodiment, the case where different pavement materials are laid up and down in two layers at the same time has been described as an example. However, the present invention is not limited to this, and only one kind of pavement material is laid down and laid down. Also in this case, a leveling machine including a plurality of hoppers 2 and 3 can be used. In this case, only one spreading screw 5, 7 and one screed 8, 9 are sufficient, for example, the front spreading screw 5
Also, the front screed 8 becomes unnecessary. In other words, it suffices to adopt a structure in which the paving material discharged from the front hopper 2 is directly supplied to the rear spread screw 7 by the bar feeder 4.

Further, by providing the front hopper 2 and the rear hopper 3 for storing the pavement material, the road surface is spread in two layers in the vertical direction, and the road surface is laid as shown in FIG. It is also possible to adopt a so-called multi-layer leveling structure in which different paving materials are leveled in the left-right direction. In this case, as shown in FIGS. 11 and 12, the paving material Hc paid out from the front hopper 2 via the bar feeder 4 at the substantially center in the left-right direction of the self-propelled vehicle is spread by the front spreading screw 5 from side to side. As shown in FIG. 12 (a), the central flat cover plate 7
Zone Z surrounded by the outer side of 0 and left and right partition plates 71 and 72
a, Za. On the other hand, the paving material Hd supplied directly from the rear hopper 3 is supplied to the rear spreading screw 7.
And the area Zc further outside the center area Zb and the left and right plane covering plates 75
To supply. Thereafter, these paving materials are spread by screed 9 so that predetermined left and right portions where road depressions are likely to be formed as shown in FIG.
, And the other parts can be paved with the paving material Hd which is relatively inexpensive and not very resistant to wear.

In the above embodiment, the case where two hoppers of the front hopper 2 and the rear hopper 3 are provided has been described as an example. However, the present invention is not limited to this, and only one or three hoppers are provided. The above may be provided. Also,
The loading feeder 16 is not limited to a single leveling machine,
One hopper may be provided for each hopper.
