Description

[Detailed Description of the Invention] The present invention is a glass bead dispersing device used for road line construction machines, etc., which is characterized by incorporating a function of varying the dispersing width into the main body of the dispersing device by a simple means. This relates to a spraying device. Generally, a road line construction machine sprays glass beads immediately after applying welding paint, and uses the light reflection to make road markings clear even at night. In this case, the case containing the glass beads and the discharge mechanism with rollers or slits had to be replaced with ones that matched the spraying width, which was very time-consuming and required the preparation of several types of equipment, which resulted in high costs. I used to be. This invention has a spreading width of 100 mm, 150 mm, 200 mm, and 300 mm.
Focusing on fixed dimensions such as mm,...450mm, we installed multiple simple shielding plates near the discharge port with adjustment screws that can move the shielding plates up and down.
By providing it continuously across its entire width,
It was devised to achieve the purpose easily and inexpensively.

A detailed description will be given below based on examples according to the drawings.

Next, the operation will be explained according to the drawings. First, when the road line construction machine 1 is pushed through the handle 11 and the slitter 2 is operated, the welding paint is applied to the road surface by the slitter 2. Immediately after that, the glass bead dispersing device installed behind the slitter 2 is operated to disperse an appropriate amount of glass beads to achieve the purpose. Next, the case of changing the spreading width will be explained. Considering the case where glass beads 16 are not scattered at first, if the adjusting screws 19a, 19b, and 19c are turned to bring the case 15 and the tip of the shielding plate 18 into close contact, the glass beads 16 will not be scattered. Next, when the adjusting screw 19a is turned in the opposite direction, the shielding plate 18a is pulled up while sliding on the surface of the plate 21. In other words, in FIG.
A gap is formed between a and the case 15, and glass beads are scattered through this gap with a width W1 as shown in FIGS. 6 and 7. In this case, the amount of spraying is adjusted by the roller 13 and the elastic body 17, and the shielding plate 18 only changes the width of the spraying. For the same reason, when the adjustment screw 19b is loosened, glass beads are scattered with a width W2, and when the adjustment screw 19c is loosened, glass beads are scattered with a width W3. In this way, the spreading width can be changed accurately with simple operations, greatly improving work efficiency. The ranges that can be changed in the example of the embodiment shown in FIG. 5 are as follows: The adjustment screw 19a changes the spreading width W1, the adjusting screw 19b changes the spreading width W2, the adjusting screw 19c changes the spreading width W3, the adjusting screw 19a, 19b, spreading width W1+W2, adjustment screws 19a, 19b
Accordingly, the spreading width W1 + W2, adjustment screws 19a, 1
With 9b and 19c, it is possible to change the spreading width in six ways: W1+W2+W3.

The features of the present invention can be summarized as follows.

(1) A wide variety of spreading widths can be changed using a simple mechanism and operation.

(Example) 3 ways for 2 shielding plates, 6 ways for 3 shielding plates, 10 ways for 4 shielding plates (2) Roller, slit discharge machine, case, etc. for changing the spreading width Dedicated parts are no longer required, and the spray width can be changed with an inexpensive unit.

(3) There is no need to replace rollers, slit discharge machines, or cases, and the spreading width can be changed with simple operations, greatly improving work efficiency.
