Description

[Detailed explanation of the idea] The present invention relates to an on-road recycling machine.

A roadside recycling machine with a conventional mixing device is
The machine is equipped with a two-shaft mixing device with shafts arranged parallel to the machine's direction of movement, with a material input port located at the front in the machine's direction of movement, and a mixture discharge port at the rear. Therefore, if the above-mentioned mixing device is employed, the total length of the machine becomes long, and when used on the road, it is inconvenient to handle. Further, when implementing a reforming method that does not supply a new mixture, the above-mentioned device is unnecessary, and the initial cost of the machine increases.

The present invention eliminates these drawbacks and also
This was proposed with the aim of providing an improved on-road recycling machine that can switch between transportation, mixing, and agitation operations by replacing some parts, and can be assembled into a compact device.
A heater disposed at the lower center of the vehicle body, a scarifier ear disposed sequentially behind the heater on the vehicle body, a first screw and blade that can be raised and lowered, a second screw and screed, and a scarifier disposed on the vehicle body in the longitudinal direction. The bar conveyor is provided with a bar conveyor whose discharge position can be changed between the first screw and the second screw, and a mixture supply hopper is disposed on the vehicle body at the front part of the bar conveyor, and the first screw is divided into left and right. , and is capable of forward and reverse rotation independently to the left and right, the central part of the blade is configured to be convertible into a screw or a paddle, and the central part of the blade is configured to be openable and closable. be.

Since the road reclamation processing machine according to the present invention is configured as described above, when used for road refilling, the asphalt mixture produced by scraping asphalt pavement that has been preheated by a heater with a scarifier is scraped into the first scraper. Move to a lower part of the road. At this time, the first screw is divided into left and right parts and is configured to be able to rotate forward and reverse independently, so that the asphalt mixture can be moved efficiently. After the asphalt mixture is moved in this way, the blade with an open center part is adjusted to a predetermined height, leveled, and compacted with a screed.

Next, when using it for repaving, when discarding a part of the asphalt mixture scraped up by the scarifier, the central part of the blade is closed and the first
The screw is rotated, the mixture is discharged onto the edge of the road, and the remaining mixture is leveled onto a flat surface while being adjusted to a predetermined height using a blade.

The new asphalt mixture is then fed and discharged from the mixture supply hopper via the bar conveyor to the upper part of the second screw, spread on top of the old mixture, and leveled with a screed.

Furthermore, when used in remixing, the asphalt mixture scraped by the scarifier is collected in the center by a first screw which is divided into left and right parts and can be rotated forward and reverse independently for the left and right sides. By attaching a paddle to the center of the first screw, the new asphalt mixture supplied from the bar conveyor and the old asphalt mixture collected by the first screw are mixed, and It is transported through the center to the second screed and leveled with a screed.

Furthermore, as an example of the reform construction method, the central part of the blade is opened and the old asphalt mixture is collected in the center by the first screw, and the mixture at the edge and center of the road is mixed to equalize the mixture difference. The second screw and screed are used to level the surface again.

In this way, in the on-road recycling machine according to the present invention, the center part of the first screw in the mixing device is configured to be replaceable with the screw or paddle, so that by selecting the parts in the center part, it is possible to dispose of the waste. Since the device and the mixing device can be used together, and the mixing device is installed in a direction perpendicular to the traveling direction of the vehicle body, the overall length of the processing machine can be reduced compared to the conventional one, and As mentioned above, the present invention has many advantages, such as being able to employ many types of road reclamation methods with a single machine.

The present invention will be described below with reference to the illustrated embodiments.

1 is a heater for heating the asphalt pavement 3 disposed at the bottom of the vehicle body 2, and a scarifier 4 is disposed at the rear of the heater 1;
A first screw 5 is disposed on the vehicle body 2 to which the granular asphalt mixture scraped by the asphalt mixture is fed.

The first screw 5 is divided at the center into left and right screws 5a and 5b, each of which is configured to be capable of forward and reverse rotation independently. A blade 6 is disposed immediately after the first screw 5, and the blade 6 moves up and down at the same time as the first screw 5.
It is configured so that its vertical position can be adjusted. A gate 7 is disposed in the central opening 6a of the blade 6, and the central opening 6a is opened and closed by the gate 7 as required by a hydraulic cylinder or the like. Further, both the screw and paddle 8 parts are attached to the center part of the first screw 5 so as to be replaceable.

Behind the blade 6 in the vehicle body 2 is a second blade.
A screw 9 is provided, and the second screw 9 is divided at the center into left and right screws 9a and 9b, each of which is configured to be capable of forward and reverse rotation independently.

A screed 10 is disposed behind the second screw 9 in the single vehicle body 2 and spreads the asphalt mixture spread by the second screw 9 onto the road.

Further, a bar conveyor 11 is disposed in the vehicle body 2 in the longitudinal direction thereof, and receives new asphalt mixture from a hopper 12 disposed at the front of the vehicle body 2 and transports it from the front to the rear of the vehicle body 2, The paper can be selectively discharged onto the first screw 5 or the second screw 9 as desired.

Therefore, when the road reclamation treatment machine shown in the illustrated embodiment is used for road refilling, the asphalt mixture produced by scraping the asphalt pavement 3 heated by the heater 1 with the scarifier 4 is scraped onto the first scraper 5. Send to left and right Screw 5
Rotate parts a and 5b to move the mixture to the lower part of the road. After the asphalt mixture has been moved in this manner, it is leveled to a flat surface while adjusting the blade 6 with the open central opening 6a to a predetermined height, and then compacted with a screed 10. At this time, if it becomes necessary to dispose of the excess asphalt mixture, the central opening 6a of the blade 6 is closed with a gate 7.

Next, the place to use for repave, Scarifiya 4
When discarding a part of the asphalt mixture scraped up, close the blade center opening 6a with the gate 7, rotate the left and right screws 5a and 5b of the first screw 5, and dispose of the mixture at the edge of the road. is discharged, and the remaining mixture is leveled onto a flat surface while adjusting it to a predetermined height using the blade 6.

The new asphalt mixture is then transferred from the mixture supply hopper 12 to the second bar conveyor 11.
It is fed and discharged to the top of the screed 9, spread on top of the old mixture, and leveled with the screed 10.

Furthermore, when used for remixing, the asphalt mixture scraped by the scarifier 4 is collected in the center by driving and rotating the left and right screws 5a and 5b of the first screw 5. At this time, as shown in FIG. 5, by attaching a paddle 8 to the center of the first screw 5, the new asphalt mixture supplied from the bar conveyor 11 and the old asphalt mixture collected by the first screw The asphalt mixture is mixed with the asphalt mixture, transported to the second screw 9 through the central opening 6a of the blade 6, and leveled with the screed 10.

Furthermore, as an example of the reform construction method, the central opening 6a of the blade is opened, the old asphalt mixture is collected in the center by the first screw 5, and the mixture at the edge and center of the road is mixed to make the mixture difference uniform. 2nd screed 9 and screed 10
This is something that will be leveled once again.
