Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rubber chip mixer truck for paving, which is suitable for paving a road having a narrow width and many curves with rubber chips.

(Prior Art) Generally, a method of paving the above-mentioned paved surface with rubber chips is known as a method of giving soft treading feeling and water permeability to the paved surface of asphalt concrete or concrete. According to this method, a primer is applied to a pavement surface such as asphalt concrete or a base such as a bridge made of iron plate, and a rubber chip, a binder, a toner, a catalyst, and a mixture of other additives are sprayed on this application surface, The layer of the rubber chip mixture is leveled to a uniform thickness by pressing the laid tree while swinging it horizontally, and then the layer is spread with a hot roller and surface-finished with an iron.

FIG. 3 shows an example of a rubber chip mixer truck for paving used in the above method. A pair of left and right caterpillars 2 are provided under the chassis 1, and the left and right caterpillars 2 are driven by an engine 3 on the front left side of the chassis 1. An engine generator 4 equipped with an engine dedicated to power generation is installed on the rear side of the engine 3, and a mixing tank 5 for additives and catalysts is fixed above the generator 4. A mixer motor 6 that receives power from the generator 4 and a box-shaped mixer stand 7 that covers the mixer motor 6 are installed behind the generator 4, and the mixer 8 is fixed on the mixer stand 7. It A discharge chute 9 is provided on the bottom plate of the mixer 8 so as to project downward and rearward, and the tip of the discharge chute 9 opens rearward of the chassis 1. Reference numeral 10 is an air compressor, 11 is a primer pressure feeding tank, 12 is a primer injection nozzle, and the tip 9a of the discharge chute 9 is located above and behind the primer injection nozzle 12, and the road after the injection of the primer is performed. The rubber chip mixture is sprinkled on top.

FIG. 4 shows an aspect of pavement using the above mixer truck for rubber chips. In FIG. 4, 13 is the above-mentioned rubber chip mixer car, 14 is a screed car for leveling the rubber chip mixture on the road, and 15 is a golf course.
The walkway 15 is preliminarily paved with asphalt concrete or the like, and layout tapes 17 are attached along both side edges of an area 16 having a predetermined width to be paved with rubber chips. Then, pavement materials such as rubber chips and binders are put into the mixer 8, and the mixer truck 13 is run while stirring and mixing these, and the primer is jetted from the jet nozzle 12 at the rear part, and the left and right layouts of the path 15 are laid out. The area 16 between the tapes 17, 17 is provided with a primer, on which the rubber chip mixture is sprinkled, which is leveled and spread by the rear screed wheel 14. In FIG. 4, reference numeral 18 denotes a rubber chip spraying area, and 19 denotes a rubber chip layer after pressure spreading. When the screed wheel 14 passes and the above-mentioned leveling and spreading work is completed, the rubber chip layer
The shoulder portion of 19 is molded by an electric iron, and then the layout tape 17 is removed.

(Problems to be Solved by the Invention) However, in the rubber tip mixer wheel 13 described above, while the stirring blade (not shown) of the mixer 8 rotates about the vertical axis in a constant direction at a constant speed, Since the discharge chute 9 was fixed right behind, the rubber chip mixture could not be properly dispersed in the center of the road at a narrow curve, such as a golf course, and after the above-mentioned dispersion. It became difficult to level the screed wheel 14 of this, and required a lot of trouble.

The present invention provides a rubber chip mixer for pavement that can spray the rubber chip mixture in the center of a curve of a narrow road such as the above-mentioned golf course.

(Means for Solving the Problem) A rubber chip mixer vehicle for paving according to the present invention is such that a mixer for rubber chips is installed on a chassis that is driven by an engine, and a discharge port is opened at a bottom rear end of the mixer.
A discharge chute is connected to this discharge port downward and rearward, and a mixture of rubber chips, binder, toner and the like mixed by the rubber chip mixer is discharged on the road from the discharge chute, in the rubber chip mixer vehicle for pavement, A damper for adjusting the degree of opening is provided at the discharge port of the mixer, and the discharge chute is connected so that the tip of the discharge chute swings left and right.

(Operation) When the paving rubber chip mixer truck of the present invention is run and the mixer on the truck is driven, the rubber chips, binder and the like are mixed by this mixer, and this mixture is sprayed on the road from the rear discharge chute. Then, when the mixer truck approaches the curve of the road, the discharge chute is turned to direct its tip toward the inside of the curve, so that the mixture is sprayed to the center of the road. Further, when the stirring blade of the rubber tip mixer passes through the discharge port, the discharge amount of the mixture is determined depending on whether the discharge chute is directed in the rotation direction of the stirring blade or in the opposite direction, and depending on the remaining amount of the rubber chip mixture. When there is a difference, the damper is rotated to adjust the opening degree of the discharge port of the mixer to make the discharge amount uniform.

(Embodiment) In FIGS. 1 and 2, reference numeral 8 denotes the rubber chip mixer, which has a cylindrical body portion 21 and a bottom plate covering the lower surface thereof.
22, a stirring shaft 23 penetrating the center of this bottom plate 22, this stirring shaft
Blade 25 and stirring shaft 23 fixed to arm 23 via arm 24
It is composed of a support 26 and the like that supports the upper end of the.

A vertical damper shaft 27 is rotatably attached to the outer surface of the rear end portion (right end in the figure) of the body portion 21 via a pair of upper and lower bearings 26, 26, and the bottom plate 22 is attached to the lower end of the damper shaft 27.
A damper 28 that covers the discharge port 22a that opens at the rear end is fixed, and a damper handle 29 is fixed rearward in the middle of the damper shaft 27. In addition, the discharge port 22 opening to the bottom plate 22
The rim of a is formed in an arc shape centered on the damper shaft 27.

Then, on the lower surface of the bottom plate 22, along the edge of the discharge port 22a, an arc-shaped chute guide 30 extending outwardly is fixed, for discharging the rubber chip mixture to the guide 30. The discharge chute 31 is mounted rotatably. The discharge chute 31 includes a cylindrical portion 32 in which a rear portion of a vertically standing cylinder is flattened, a bottom plate 33 that covers the lower surface of the cylindrical portion 32 and is inclined rearward downward, and a flange fixed to an arc portion of the upper end of the cylindrical portion 32. 34, the flange 34 is slidably fitted to the guide 30, and the rubber chip mixture is discharged from the chip discharge port 35 opened at the lower end of the rear portion of the cylindrical portion.
Then, the chute handle is provided on the upper end of the rear portion of the above-mentioned tubular portion 32.
36 is projected rearward.

In the above structure, when the damper handle 29 is turned left or right, the left or right side of the discharge port 22a opening in the bottom plate of the mixer 8 is opened, and the discharge port 22a is opened in accordance with the turning angle of the handle 29. The opening degree of is adjusted. Further, when the chute handle 36 is turned left or right, the tip discharge port 35 at the lower end of the discharge chute 31 faces left or right, and the spraying position of the rubber tip mixture moves left or right.

(Effect of the Invention) As described above, the present invention provides a damper for adjusting the degree of opening of the mixer for a rubber chip placed on a trolley, and a discharge chute rearward and downward is provided at this discharge port. Since the tip is connected so that it can swing to the left and right, it is possible to spray the rubber chip mixture in the center of the curve of a narrow road such as a golf course, and evenly spread the amount. Therefore, it is possible to facilitate the leveling work after the spraying.
