DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bead scattering apparatus.

[0002]

2. Description of the Related Art As a conventional road marking line coater, a road marking line coater with a motor is generally used. A narrow road marking line, such as a line, a lane boundary line, etc., which is applied at a structural and operational point of the coating machine, for example, a wide road marking line such as a pedestrian crossing or a stop line. I didn't do that.

[0003]

That is, in such a road marking line applicator with a motor, since the shoe is opened and the forward lever of the applicator main body is operated separately, this applicator has a wide width. When applying road marking lines for roads, the material outflow area increases, and if it is a separate operation, a lot of material will flow out at the start of construction, which will be uneconomical and can be applied neatly. There was a problem that it was not possible.

[0004] Conventionally, there is a manual type road marking line applicator for applying a wide road marking line. However, this is heavy, and especially when climbing a hill, a considerable burden is imposed on the builder. And increased labor. There has been no bead dispersing device attached to such a road marking line applicator for spraying glass beads on the road marking line.

[0005]

SUMMARY OF THE INVENTION A bead dispersing apparatus according to the present invention has been made to solve the above-mentioned problem, and has a discharge material tank containing a coating material having a discharge port at a lower portion, and a discharge material tank. When the fabric tank is higher than the road,
The glass beads lower feed mechanism consisting of a pair of rotating bodies does not rotate, so that the glass beads are not scattered from the glass bead tank installed above the lower feed mechanism, and the spray material tank When the is mounted on the road surface, the glass beads lower feed mechanism composed of a pair of rotating bodies rotates, and the glass beads are sprayed from the glass bead tank installed above the lower feed mechanism. It is characterized by the following.

Further, the bead dispersing apparatus according to the present invention comprises a wide discharge material tank containing a coating material having a discharge port at a lower portion, and a discharge port opening / closing lever capable of opening and closing the discharge port. When the outlet opening / closing lever is opened, the wheels are automatically driven, and at the same time, the discharge port is opened and the coating material flows out to form a coating film on the road surface, and when the discharge port opening / closing lever is closed, the driving of the wheels is stopped, A bead spraying device attached to a motorized road marking line coating machine configured to stop the flow of the coating material by closing the discharge port, wherein the wide spraying material tank rises above the road surface. The glass beads lower feed mechanism composed of a pair of rotating bodies does not rotate, so that the glass beads are not sprayed from the glass bead tank installed above the lower feed mechanism, and When the wide discharge material tank is installed on the road surface, the lower feeding mechanism for the glass beads, which is composed of a pair of rotating bodies, rotates, and the glass beads from the glass bead tank installed above the lower feeding mechanism. Are configured to be dispersed.

Next, a description will be given of a construction procedure of a motor-applied road marking line applicator provided with the bead scattering device according to the present invention. First, the tank lift lever 7 is pulled backward to release the engagement between the pair of angles 5 and the hook 9, and the wide discharge material tank 4 is brought into contact with the road surface. Here, when the clutch lever 18 is operated, the clutch lever 1
The clutch pin 17 is turned off by the operation of the clutch link shaft 26, the spring 29 and the clutch pin pushing lever 28 which are integrated with the shaft 8, and the forward / backward control lever 19 is formed in the lever guide plate 20 by the length. The motorized road marking line applicator does not operate even if it is located behind the hole 22.

Then, when the discharge port opening / closing lever 30 is opened, the clutch arm 31 is connected to the clutch link shaft 26.
, The clutch pin 17 is turned on, the rear wheel 3 is driven, and at the same time, the discharge port is opened and the coating material flows out to form a predetermined coating film.

When the discharge port opening / closing lever 30 is closed, the clutch arm 31 is connected to the clutch link shaft 26.
The clutch pin 17 is depressed by the spring 29 to be turned off, the driving of the rear wheel 3 is stopped, and at the same time the discharge port is closed, so that the coating material does not flow out.

The speed during construction can be arbitrarily varied by moving the forward / reverse control lever 19 to a position behind a long hole 22 formed in a lever guide plate 20.

When the handle 6 is pushed downward after the stop, the pair of angles 5 of the wide discharging material tank 4 are respectively locked by the hooks 9 and the clutch pins 17 are moved back and forth with the off state. it can. When the clutch pin 17 is turned on to move back and forth, the forward / reverse control lever 19 is set to the neutral position (notch 2 of the long hole 22).
2a), the clutch lever 18 is inserted into the neutral position (notch portion 21a of the long hole 21), and the forward / backward control lever 19 is moved back and forth in the long hole 22 to move at an arbitrary speed. it can.

The operation of the glass bead dispersing device 33 according to the present invention attached to such a motor-equipped road marking line applicator will be described. As shown in FIG. 12, when the pair of angles 5 attached to the wide discharge material tank 4 are locked by the hooks 9, the claw 43 lifts the clutch hook 41, and the clutch gear The pair of rotating bodies 35a and 35b are not rotated even when the driving gear 39 moves back and forth since the driving gear 39 is separated from the driving gear 40, and the glass beads are not sprayed.

As shown in FIG. 13, when the tank lift lever 7 is pulled backward to release the engagement between the pair of angles 5 and the hook 9, and the wide discharge material tank 4 is brought into contact with the road surface, The claw portion 43 also goes down, and the clutch hook 41
Is pulled by the spring 42, and the clutch gear 3
9 meshes with the drive gear 40. By pulling backward, the axle 2a of the front wheel 2 rotates, and a pair of rotating bodies 35a,
35b is a second spur gear 38 meshing with the first spur gear 37
The glass beads are sprinkled by rotating inward. At this time, glass beads are naturally mixed into the coating film formed by the application material flowing out from the wide discharging material tank 4.
