  The grip part with a hole of the on-vehicle stirring rod for a vacuum vehicle described in this section is such that the end of the bar opposite to the stirring plate is annular on the plane perpendicular to the line connecting the center of gravity of the stirring plate and the through hole Therefore, the hole of the grip part with a hole is formed in such a manner that it opens in a direction parallel to the center of gravity of the stirring plate and the line connecting the holes. On the other hand, the through hole of the stirring plate is formed so as to open in a direction orthogonal to the line connecting the center of gravity of the stirring plate and the through hole. Therefore, the insertion direction of the in-vehicle bracket with respect to the through hole of the stirring plate is orthogonal to the insertion direction of the in-vehicle bracket with respect to the grip portion with the hole in the bar.

Then, when the in-vehicle bracket is inserted through the through hole formed at a position eccentric from the center of gravity of the stirring plate, the center of gravity of the stirring plate is located below the through hole (in-vehicle bracket), and is suspended from the in-vehicle bracket. It is done. At this time, the grip portion with a hole is inserted into the in-vehicle bracket with the opening direction of the hole directed up and down.
Therefore, even if the on-vehicle stirring rod swings due to the impact of running the vacuum vehicle, both the through hole of the stirring plate and the hole of the grip portion with the hole of the bar are unlikely to fall off from the on-vehicle bracket at the same time, and The rocking converges to a mode in which the center of gravity is located below the through hole of the stirring plate, so that inadvertent dropping from the in-vehicle bracket is avoided.

Therefore, the vehicle-mounted stirring rod is held by the first bracket in a state where the stirring plate can move in the vehicle front-rear direction and swing around the first bracket. On the other hand, when the grip portion with a hole of the bar is inserted into the hook-shaped second bracket extending in the vehicle vertical direction, the movement of the grip portion with the hole in the vehicle front-rear direction is limited. It will be in a state where it can swing along the hook shape.

Therefore, even if the on-vehicle stirring rod of the vacuum vehicle described in the above item (1) swings due to an impact or the like during traveling of the vacuum vehicle, the engagement between the first bracket and the through hole of the stirring plate is released. The movement in the vehicle front-rear direction necessary for this is limited by the engagement between the grip portion with a hole and the second bracket, and the engagement between the second bracket and the grip portion with a hole in the bar is released. The required vertical movement is limited by the engagement of the first bracket and the through hole in the stirring plate.
In addition, when the first bracket is inserted into the through hole formed at a position eccentric from the center of gravity of the stirring plate, the center of gravity of the stirring plate is positioned below the through hole (first bracket). At this time, the grip portion with a hole is inserted in the second bracket in a mode in which the opening direction of the hole is directed up and down, so that inadvertent dropping from the in-vehicle bracket is avoided.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. Here, parts that are the same as or equivalent to those of the prior art are assigned the same reference numerals, and detailed descriptions thereof are omitted.
FIG. 1 shows an in-vehicle stirring rod 26 for a vacuum vehicle according to an embodiment of the present invention, and in-vehicle brackets 30 and 32 provided in the vacuum vehicle for mounting the in-vehicle stirring rod 26. Yes. As shown in FIGS. 1 (a) and 1 (b), the vehicle-mounted stirring rod 26 is positioned at a position eccentric from the center of gravity G of the stirring plate 16, and the first bracket 30 (FIGS. 1 (c) to (f)). A through hole 28 is formed for insertion of the reference). In the illustrated example, the bar 18 extending in a direction orthogonal to the stirring plate 16 protrudes from the position of the center of gravity of the stirring plate 16. Further, the end of the bar 18 opposite to the stirring plate 16 is annularly folded on a plane perpendicular to the line L connecting the center of gravity G of the stirring plate 16 and the through hole 28 to form a grip part 18a with a hole. Has been. The second bracket 32 (see FIGS. 1C to 1F) is inserted through the hole 20 of the grip portion 18a with a hole.

As shown in FIGS. 1C to 1F, the first bracket 30 is formed in a pin shape extending in the vehicle front-rear direction with the tip portion directed rearward. In the illustrated example, the first bracket 30 is fixed to the tank 12 of the vacuum vehicle 10, and is bent in an L shape to limit the movement of the stirring plate 16 in the front direction of the vehicle, and the front end portion is rearward of the vehicle body. It is growing. The second bracket 32 is formed in a hook shape extending in the vehicle vertical direction. In the illustrated example, the U-shaped engagement portion 32a is a linear shape fixed to the tank 12 of the vacuum vehicle 10. It is held at an appropriate position by the base end portion 32b. The first bracket 30 and the second bracket 32 are positioned so that the bar 18 of the vehicle-mounted stirring rod 26 is held horizontally.
In addition, it is good also as arranging the position of the 1st bracket 30 and the 2nd bracket 32 reversely as needed.

  According to the embodiment of the present invention configured as described above, the following operational effects can be obtained. First, the grip portion 18 a with a hole of the on-vehicle stirring rod 26 is on the surface where the end of the bar 18 opposite to the stirring plate 16 is orthogonal to the line connecting the center of gravity G of the stirring plate 16 and the through hole 28. The hole 20 of the grip part 18a with a hole is formed in such a manner that it opens in a direction parallel to the center of gravity G of the stirring plate 16 and the line connecting the holes. On the other hand, the through hole 28 of the stirring plate 16 is formed so as to open in a direction perpendicular to the line L connecting the center of gravity G of the stirring plate 16 and the through hole 28. Therefore, the insertion direction of the first bracket 30 with respect to the through hole 28 of the stirring plate 16 and the insertion direction of the second bracket 32 with respect to the hole 20 of the holed grip 18a portion of the bar 18 are orthogonal to each other.

When the first bracket 30 is inserted into the through hole 28 formed at a position eccentric from the center of gravity G of the stirring plate 16, as shown in FIG. The stirring plate 16 is suspended from the first bracket 30 in such a manner that the center of gravity G of the stirring plate 16 is located below the bracket 30). At this time, the grip portion 18a with a hole is inserted into the second bracket 32 with the opening direction of the hole 20 up and down, and is caused by the position of the center of gravity G with respect to the through hole 28 of the stirring plate 16. Due to the posture change of 26, as shown in FIG. 1 (f), the second bracket 32 is held in a state in which it is rotated 1/2 to the back side of the hook shape.
Therefore, even if the vehicle-mounted stirring rod 26 swings due to an impact during travel of the vacuum vehicle 10, both the through hole 28 of the stirring plate 16 and the hole 20 of the grip portion 18a with the hole of the bar 18 are simultaneously mounted on the vehicle-mounted bracket 30, It is hard to fall into the situation of dropping off from 32, and its swing converges to a mode in which the center of gravity G is located below the through hole 28 of the stirring plate 16, and inadvertent dropping off from the in-vehicle brackets 30, 32 occurs. It will be avoided.

  Moreover, according to the vacuum wheel which concerns on embodiment of this invention, the pin-shaped 1st bracket 30 extended in the vehicle front-back direction is penetrated with respect to the through-hole 28 of the stirring plate 16, and it will be in a so-called skewered state. Therefore, the on-vehicle stirring rod 26 is held by the first bracket 30 in a state where the stirring plate 16 can move in the vehicle front-rear direction and swing around the first bracket 30. On the other hand, when the grip portion 18a with a hole of the bar 18 is inserted into the hook-like second bracket 32 extending in the vehicle vertical direction, the movement of the grip portion 18a with a hole in the vehicle front-rear direction is limited. The U-shaped engagement portion 32a of the second bracket 32 can swing along the hook shape.

  Therefore, even if the vehicle stirring rod 26 is swung due to impact or the like during travel of the vacuum vehicle 10, it is necessary to disengage the first bracket 30 from the through hole 28 of the stirring plate 16. Movement in the longitudinal direction of the vehicle is limited by the engagement between the grip portion 18a with a hole and the second bracket 32, and the engagement between the grip portion 18a with a hole of the second bracket 32 and the bar 18 is released. Necessary vertical movement is limited by the engagement between the first bracket 30 and the through hole 28 of the stirring plate 16. In this manner, the first and second brackets 30 and 32 complement each other so as to prevent the in-vehicle stirring rod 26 from falling off.

  When intentionally removing the in-vehicle stirring bar 26 from the in-vehicle bracket so as to use the in-vehicle stirring bar 26, as shown in FIG. The U-shaped engaging portion 32a of the bracket 32 is rotated by half along the hook shape of the U-shaped engaging portion 32a to remove the grip portion 18a with holes from the second bracket 32. By removing the through hole 28 of the stirring plate 16 from the bracket 30, the vehicle-mounted stirring rod 26 can be removed.

  FIG. 2 shows a first bracket 34 according to the application example. The first bracket 34 of FIG. 2 is provided with a guard portion 34a that prevents the stirring plate 16 from contacting the tank 12 by being bent into a crank shape. Therefore, as shown by a two-dot chain line in FIG. 2A, even if the vehicle-mounted stirring rod 26 swings around the through hole 28 of the stirring plate 16 due to an impact or the like when the vacuum vehicle 10 travels, Contact of the stirring plate 16 with the tank 12 can be avoided by the contact of the stirring plate 16 with the guard portion 34a of the first bracket 34.

  The embodiment of the present invention is as described above. However, as long as the through hole 28 is formed in the stirring plate 16 and the grip portion 18a with a hole is formed in the bar 18, each part of the on-vehicle stirring rod 26 is provided. The specific shape of can be changed as appropriate. Also, the specific shapes of the first brackets 30 and 34 and the second bracket 32 can be appropriately changed as long as the first brackets 30 and 34 and the second bracket 32 can be inserted into the through holes 28 or the grip portions 18a with holes. It is.
