Description

[Detailed Description of the Invention] The present invention relates to a hopper device installed in an asphalt finisher, a base paper laying machine, etc.

For example, an asphalt finisher is conventionally equipped with a hopper device 1 as shown in FIG. The hopper device 1 includes a pair of left and right wings 2a, 2b that are rotatable up and down about mutually parallel axes, and is disposed at the front of a traveling vehicle body 3. Then, with the wings 2a and 2b rotated downward, asphalt composite material (hereinafter referred to as composite material) is removed from the dump truck.
The bar feeder 4 installed at the bottom sends it to the rear spretting screw for use, and when the amount of mixed material in the device is low, the wings 2a and 2b are rotated upward. This allows the remaining composite material to fall onto the bar feeder 4 reliably.

However, in the conventional hopper device 1, when the wings 2a and 2b are erected, the composite material spills onto the road surface from the front end sides of the wings 2a and 2b, and this spilled composite material is spread over the road surface. In addition to being a hindrance to work, bar feeder 4 of composite material
The efficiency of transfer to the plant was also not necessarily satisfactory. Therefore, as shown in FIG. 10, the present applicant has proposed that the left and right wings 5a, 5b be centered around a pair of oblique axes whose lateral spacing becomes shorter as they approach the front end of the vehicle body 3. As a result, we have developed an oblique shaft type hopper device 6 that is rotatable up and down. However, even in this hopper device 6, when the wings 5a and 5b are erected, the mixture still falls out from the front side of the central part, although the amount is extremely small compared to the conventional general hopper device 1. It was also necessary to further improve the efficiency of transferring the material to the bar feeder 4.

This invention was made in view of the above circumstances,
To provide a hopper device for a leveling machine, which hardly spills mix material from the front side of the center part when the wing is erected, and which further improves the efficiency of transferring the mix material to a bar feeder. purpose.

In order to achieve the above object, the present invention includes a bottom plate, a wing connected to the bottom plate, and an intersecting side of the wing with respect to the bottom plate being substantially parallel to the oblique axis.
It consists of an inclined plate part that is inclined upward with respect to the bottom plate part, and a side plate part that is connected to this inclined plate part, etc. When the wing is erected, due to the inclination of the inclined plate part, This allows the composite material to be efficiently dropped and transferred to the center rear side.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 8.

What is shown in FIGS. 1 and 2 is an asphalt finisher, and numeral 10 in the figures is a traveling vehicle body. A bar feeder 12 is installed at the front of the vehicle body 10, and a bar feeder 12 whose rear end side extends to the front of the spreading screw 11 is installed. 10, it becomes shorter as it approaches the front end side, and each is approximately
It is located above the bar feeder 12 and is attached to be rotatable in the vertical direction via a pair of hinges 14a and 14b that are symmetrically arranged at an angle of 21 degrees. This pair of wings 13a, 1
3b, one side of which is the hinge 14a, 14, respectively.
The bottom plate portions 15a, 15b attached to
The intersecting sides m and n with a and 15b are the hinge 14
slanted plate parts 16a, 16b that are substantially parallel to the axes (oblique axes) of a, 14b and inclined upward at an angle of about 15 degrees with respect to the bottom plate parts 15a, 15b;
These inclined plate parts 16a, 16b and the bottom plate part 15
connected to the rear sides of the bottom plate parts 15a, 15b.
5b and side plate portions 17a, 17b that are substantially perpendicular to the bottom plate portions 17a, 17b, and cylinder devices 18, 18, one end of which is rotatably attached to the vehicle body 10 via a bracket, are mounted on the lower surface of the bottom plate portions 15a, 15b.
The tips of the piston rods 19, 19 are rotatably connected to each other via a connecting member. Then, by operating these cylinder devices 18, 18, the wings 13a, 13b are moved to the hinges 14a, 14.
The wings 13a, 13b can be rotated up and down around b.
13b is the bottom plate portion 15 as shown by the solid line in FIG.
The bottom plate portions 15a and 15b can be tilted down until they are approximately horizontal, or raised to a position where the bottom plate portions 15a and 15b form an angle of approximately 49° with respect to the horizontal, as shown by the two-dot chain line.

In the figure, 20 is a reinforcing member for the bottom plate portions 15a, 15b and the inclined plate portions 16a, 16b of the wings 13a, 13b, and 21 is a hook. Further, a drive section 10a that accommodates a drive device for the traveling vehicle body 10, etc.
A pair of left and right cover plates 22a, 22b are provided on the front surface of the drive section 10a in order to eliminate the gap between the front surface of the drive section 10a and the rear side plate sections 17a, 17b of the wings 13a, 13b. The cover plates 22a, 22b are attached to the drive unit 10a by bolts 23 inserted into elongated holes h, and even after the wings 13a, 13b are installed at the front of the vehicle body 10, the bolts 23 cannot be attached. By changing the position, the cover plates 22a, 22
The gap between the wings 13a and 13b can be adjusted.

However, in the case of the hopper device having the above configuration,
Rotate the wings 13a and 13b downward to
As shown by the solid line in the figure, the composite material is received from the dump truck and put to use. When the amount of composite material decreases, the wings 13a, 13
b is rotated upward to stand up to the position shown by the two-dot chain line in FIG.
a and 13b include inclined plate parts whose intersecting sides m and n with respect to the bottom plate parts 15a and 15b are substantially parallel to the axes of the hinges 14a and 14b, and which are inclined upward at a predetermined slope with respect to the bottom plate parts 15a and 15b. 16a, 16
b is formed, the remaining composite material does not fall out from the front side of the central part, and is directed towards arrow A in Figure 3.
The entire amount is efficiently dropped and transferred in the direction shown in
They are gathered on Barfeeda 12.

By the way, in the above, the wings 13a, 1
A closing member 24 that moves up and down following the rotation of the wings 13a and 13b is attached to the proximal end side of the front end of the wing 3b, which is close to each other. It is advantageous if the member 24 closes the opening on the front side of the center portion of the member 24, since spilling of the composite material from the front side of the center portion of the wings 13a, 13b can be more reliably prevented.

As explained above, the hopper device of the present invention is
A pair of wings, each of which is rotatable up and down about a pair of oblique axes whose lateral spacing becomes shorter as it approaches the front end of the vehicle body, are provided on the bottom plate and on the bottom plate, respectively. installed in succession,
Consisting of an inclined plate part whose intersecting sides with respect to the bottom plate part are substantially parallel to each of the above oblique axes and which is inclined upward with respect to the bottom plate part, and a side plate part connected to the inclined plate part, etc. Therefore, when the wing is erected, the inclination of the inclined plate part ensures that the composite material falls and is transferred to the center rear side.
The mixture does not fall from the front side of the central part, and the efficiency of transferring the mixture to the bar feeder increases, further improving the workability of leveling work.
