Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stripping machine for ground coating materials of tennis courts, soccer courts, and other sports facilities.

[Conventional technology and its problems]

For example, an all-weather gland has a hard or soft coating applied to the surface of a base such as asphalt, and when repairing it, it is necessary to remove only the coating surface without causing harmful damage to the base. Conventionally, such stripping work has been carried out manually using a working tool such as a scraper, which requires a great deal of labor and time.

It is an object of the present invention to provide a ground coating material stripping machine that eliminates the disadvantages of the conventional example and can perform stripping work quickly, simply, and efficiently.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention supports a cutter device by the end arm of a self-propelled truck or a manual truck on which a driving means is mounted, and the cutter device is made of cemented carbide chips. Alternatively, a plurality of disc bodies each having a cutting edge facing downward and installed so as to move planetarily with respect to a drive shaft connected to the drive means are provided, and a plurality of sets are provided with different rotation directions. This is a summary.

[Effect]

According to the present invention, since the disc body with the cutter embedded in the lower surface moves in a planetary manner with respect to the drive shaft, it is possible to efficiently cut only the ground coating surface evenly and without cutting too deeply.
In addition, cross-shaped notches are left on the base surface below the coating surface, so that appropriate coating can be obtained again. Moreover, the cutter device does not rotate in one direction, so the work can be carried out stably. can.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a side view showing the first embodiment of the ground coating material stripping machine of the present invention, and Fig. 2 is a longitudinal cross-sectional view of the cutter device. , shows a truck on which an engine 3 as a driving means is mounted.

The truck 1 projects a lift arm 4 forward and supports a cutter device 5 at its tip, and the engine 3 is connected at one end to a V-belt pulley 7 of the cutter device 5 via a V-belt clutch 6, and at the other end. One is connected to a front wheel 11 via a V-belt clutch 8, a transmission 9, and a differential gear 10, thereby making the truck 1 a self-propelled truck with front wheel drive.

Further, the lift arm 4 is supported in the middle by a support rod 13 that hangs down from one side of a swinging lever 12 provided on the truck 1, and a buffer spring 14 is installed on this rod 13. A ball screw 15 is attached to the other side of the swinging lever 12, and a handle 16 provided at the rear of the truck 1 is connected to the ball screw 15 via a chain 17 so as to move the ball screw 15 up and down.

In the cutter device 5, as shown in FIG. 2, a shaft 26 of a V-belt pulley 7 is connected to a vertical drive shaft 21 via bevel gears 19 and 20, and a sun gear 22 is provided at the lower end of this drive shaft 21. , this gear 22 meshes with a plurality of (three in the illustration) planetary gears 23. As shown in FIG. 4, a cemented carbide chip 2 is placed under each planetary gear 23 and protrudes from the bottom surface as shown in FIG.
Attach the disc body 25 with the implanted part 4.

FIGS. 7 to 9 are perspective views showing the shapes of the cemented carbide chips 24, including those with completely pointed claws as shown in FIG. 7, and those with flat claws as shown in FIG. , or one having a conical tip as shown in FIG. 9 is conceivable, and in either case, the upper part is inserted into an insertion hole formed on the lower surface of the disc body 25 and locked by bolting. In addition, the cemented carbide chip 2
Examples of arrangements for the disc body 25 in No. 4 include cases in which they are arranged concentrically with respect to the rotational axis of the disc body 25 as shown in Fig. 5, and cases in which they are arranged in a spiral shape with a slight eccentricity as shown in Fig. 6. There are cases.

By the way, the cutter device 5 has a drive shaft 21.
There are a plurality of sets (two sets in the figure) in which a plurality of disk bodies 25 with chips 24 are incorporated so as to move planetarily relative to the disk body 25, and each set has a third disk body 25.
As shown in the figure, the directions of rotation are different: one is clockwise and the other is counterclockwise.

In addition, the whole is surrounded by a hood 27 and is rotatably attached to the lift arm 4, but there is a lever 27 above.
8 can be attached, and this can be temporarily fixed to the trolley 1 with a rod 29.

Next, to explain the usage and operation, start the engine 3, put in the V-belt clutch 8,
When the gear is set to F2, the machine moves as if it were traveling on a road.

Steering is performed using brakes attached to the front wheels 11. When working on the tennis court, change the gear to F1 and use the working speed. V for cutter
When the belt clutch 6 is engaged, the driving force of the engine 3 is transmitted to the disc body 25 via the drive shaft 21 etc., and this causes planetary motion, so that the cutter device 5 becomes idle.

In this state, cutter device 5 and handle 1 for up and down
6, the cutter device 5 is gently grounded, moved forward, and begins cutting.

Regarding the cutting action of the cutter device 5, the chips 24 perform cutting in accordance with the combined motion of the planetary gear 23's rotation and constant rotation, so that they cut the coating into small pieces to facilitate stripping and to remove the asphalt base 30. The top of the hard aggregate inside can be cut off to make it flat, while leaving a cross-like notch in the asphalt substrate to provide a shape for better adhesion of the recoating material.

While working, adjust the ground pressure with the spring 14 while checking the sharpness of the cutter device 5, and when you want to go backwards, shift the gear to R1.

When the tip 24 is worn out, with the machine stopped, turn the handle 16 to raise the lift arm 4 to the normal position, attach the attached lever 28 to raise the cutter device 5 at right angles, and use the rod 29 to raise the lift arm 4. 28 is fixed, the disc body 25 is removed and the assembly is replaced.

[Effect of idea]

As mentioned above, the ground coating material stripping machine of the present invention can efficiently perform work that conventionally relied on human power using mechanical power, and allows the tip of the cutter device to move horizontally, as well as rotate and rotate constantly. Because it rotates with both complex movements, only the coating surface can be removed without cutting too deeply.

In addition, cross-shaped notches are left on the base under the coating surface, allowing the proper shape to be re-coated.On the other hand, the cutter device is designed to prevent rotation in one direction, allowing stable work. This is something that can speed up the process.
