る。[Detailed explanation of the invention] (Industrial application field) This invention relates to a load sweeper for civil engineering machinery.
In particular, the present invention relates to a fixing device for a vertical brush of a load sweeper.

た。(Conventional technology and its problems) The work of road sweepers includes cleaning grooves, side gutters, etc. In this work, vertical brushes are used to clean grooves, side gutters, etc.
Generally, dust, foreign matter, etc. in concave areas such as side gutters are sent to a flat area of the road and removed using a horizontal brush located in the center of the sweeper. Therefore, since the vertical brush is slightly smaller in size than the sweeper body, when cleaning areas other than recesses such as ditches and side gutters, the vertical brush scrubs the road surface strongly, damaging the vertical brush and the road surface. It had a drawback that shortened its lifespan.

従来の欠点を解決した。(Means for solving the problem) According to the present invention, when a vertical brush is not required for cleaning other than recesses such as grooves and side gutters, a pin hole is installed in the link arm that holds the vertical brush and moves up and down. At the same time, the sweeper body is provided with a device that allows the lock pin to stand still at the protruding and retracted positions, and when the vertical brush is raised slightly above the road surface, the protruding lock pin is connected to the pin of the plate. The drawbacks of the prior art were solved by fixing the vertical brush by engaging the hole.

ができる。(Function) Since the vertical brushes are fixed at a position slightly above the road surface, the vertical brushes do not come into contact with the road surface during work other than ditches, side ditches, etc. where vertical brushes are not required, so there is no damage. The device of the present invention has a much longer lifespan than conventional cleaning methods, and is constructed from relatively inexpensive parts, and can be easily attached to a conventional load sweeper.

and welded to 2b. A circular bottom plate 4 is welded to one end of the pipe 3, and an L-shaped slot 8 is provided on the side surface of the pipe 3 so that the long part is parallel to the central axis XX direction. Rectangular part 8a
is curved at an acute angle in the opposite direction to the bottom plate 4. As is clear from Fig. 3, the inner diameter 3 of the pipe 3
A lock pin 5 is slidably and rotatably inserted in a, and is inserted so as to be biased in a direction opposite to the bottom plate 4 by a coil spring 7. A rod-shaped lever 6 is fixed in a substantially radial direction near the end of the locking pin 5 in contact with the spring 7, for example by driving, and the lever 6 is guided and slid in an L-shaped slot 8 of the pipe 3. ing. The lock pin assembly O having the above structure is aligned with the central axis X-X of the pipe 3.
When the vertical brush 16 is held horizontally and lifted upward from the lowered position as shown in FIG. 4 or FIG. The bracket 1 is attached to the sweeper body 11 by bolts 9 at approximately the four corners of the bracket 1 at positions where the central axis of the bracket 1 and the central axis XX of the pipe 3 coincide with each other.

論ワンタツチで行なわれる。 Next, to explain how to operate the vertical brush fixing device of the road sweeper according to the present invention, as shown in FIG. When cleaning flat areas other than gutters and gutters,
When the vertical brush 16 is lifted, the link arm 12
rotates clockwise, and the lock plate 13 fixed to the link arm 12 also rises. On the other hand, as shown in FIG.
When lever 6, which is stationary at point a, is held in hand and moved upwards while compressing spring 7, pushing in lock pin 5 and rotating, lever 6 reaches the elongated part of slot 8, and is moved by the force of spring 7. The lock pin 5 then moves to the right in the figure and fits into the hole 14 of the lock plate 13 which is raised as shown by the dotted line, fixing the lock plate 13 and the link arm 12, and therefore the vertical brush 16 in the raised position. , these operations can be performed with a single touch. Lock pin 5
To release the lever 6, which is stationary at the dotted line position at the right end of the L-shaped slot 8, as shown in FIG.
When you grasp it with your hand and move it to the left against the force of the spring 7, and when you reach the end, lower it downwards, rotate the lock pin 5, and release your hand, the lever 6 will move into the acutely curved rectangular shape of the slot 8. The lock pin 5 rests on the portion 8a as shown by the solid line, and the lock pin 5 is retracted from the position shown by the dotted line to the position shown by the solid line, and the engagement with the lock plate 13 is released, so that the vertical brush 16 can be processed. Of course, this release operation is also performed with a single touch.

The vertical brush can be fixed in a raised position with a one-touch locking pin, so you can clean road surfaces other than gutters and gutters with only the horizontal brush, and avoid damage to the vertical brush and road surface caused by the vertical brush needlessly scraping the road surface. This has the effect of prolonging the life of the vertical brush.
