[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved structure for mounting an auxiliary chute on a mixer truck.

[0002]

2. Description of the Related Art As shown in FIG. 6, a mounting structure of an auxiliary chute to a mixer car is such that one end of a wire (metal wire) 54 is connected to a mounting hole 53 provided in an ear 52 of the auxiliary chute 51. By superimposing the upper end of the auxiliary chute 51 on the lower end of the chute M1 of the mixer truck and connecting the other ends of these wires 54 with each other,
The auxiliary chute 51 was attached to the chute 55 of the mixer truck (shown by the two-dot chain line in the figure).

[0003]

However, according to such a conventional technique, since the auxiliary chute 51 is formed of a thin plate, when concrete is poured into the chute, the auxiliary chute 51 is attached as shown in FIG. Ears 52 around holes 53
There is a problem that the wire 54 is cracked 100 and the wire 54 is disengaged from the mounting hole 53, and the work of connecting the wires 54 to each other is troublesome, and there is also a problem that the concrete pouring is delayed.

The present invention has been made in view of the above points, and an object thereof is to prevent a metal wire rod for mounting from being accidentally detached from an auxiliary chute and to quickly mount the auxiliary chute. It is to provide a mounting structure for an auxiliary chute that can be mounted on a mixer truck.

[0005]

The structure for mounting an auxiliary chute on a mixer car proposed to achieve the above object is an auxiliary structure for a mixer car for connecting the auxiliary chute to the lower end of the chute of the mixer car. In the chute mounting structure, a mounting body is provided with a mounting part formed of a ring part and a hook part to form a mounting part, and by mounting the mounting part of the mounting part to the auxiliary chute, A pair of fixture main bodies are arranged on both left and right sides of the upper end of the auxiliary chute, one end of the metal wire is tied to the ring of each fixture main body, and the upper end of the auxiliary chute is attached to the lower end of the chute of the mixer truck. It is characterized in that the other end of the metal wire rod tied to the ring portion of one of the fixture bodies is entwined with the other end of the metal wire rod while being overlapped.

[0006]

According to the auxiliary chute mounting structure for the truck mixer truck of the present invention, one end of the metal wire can be attached to the auxiliary chute by being tied to the ring portion of the fitting as shown in FIG. It is possible to prevent the weight of the concrete from being concentrated on a part of the area, and as a result, it is possible to prevent a part of the auxiliary chute from being broken by the weight of the concrete and the auxiliary chute to fall.

Further, since the other end of the metal wire rod attached to one attachment body can be tied by being hooked on the hook portion of the other attachment body as shown in FIG. Can be quickly installed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An auxiliary chute mounting structure for a truck mixer vehicle of the present invention will be described below with reference to the illustrated embodiments. 1
Is a fixture for attaching the auxiliary chute 2 to the chute M1 of the mixer truck M, and is a fixture main body at both ends of the arc-shaped bent attachment part 11 so as to match the outer peripheral surface of the auxiliary chute 2. 12 is provided. The attachment part 11 has a plurality of mounting holes 1 at appropriate intervals in the length direction.
3 is drilled. The attachment body 12 is formed by integrating the ring portion 14 and the hook portion 15.

A plurality of chute mounting holes 21 are formed in one end of the auxiliary chute 2 in the circumferential direction at the same intervals as the mounting holes 13 of the fitting 1.

Reference numeral 3 denotes a curved back plate having an arc shape, and a plurality of mounting holes 31 are formed in the longitudinal direction at the same intervals as the mounting holes 13 of the mounting tool 1. FIG. 1 shows a state in which the mounting tool 1 is mounted on the auxiliary chute 2, and the mounting tool 1 is positioned below the auxiliary chute 2 and the back plate 3 is positioned above the auxiliary chute 2 so as to mount each mounting hole. 13, 21, 31
Then, the fitting 1 such as a rivet or a bolt is inserted through these fitting holes 13, 21, and 31 to fix the fitting 1 to the auxiliary chute 2 (FIG. 2).

By attaching the attachment 1 to the auxiliary chute 2 in this manner, the pair of attachment main bodies 12 are arranged at one end of the auxiliary chute 2 on both left and right sides of the wadding. Further, one end of the metal wire 5 is tied to the ring portion 14 of the fixture 1.

Next, the operation of attaching the auxiliary chute 2 to the chute M1 of the mixer truck M will be described. First, as shown in FIG. 4, the upper end of the auxiliary chute 2 is superposed on the lower end of the chute M1 of the mixer truck M. next,
As shown in the figure, the ring portion 14 of one of the fixture main bodies 12
The other end of the metal wire 5 tied to the hook is hooked on the hook portion 15 of the other attachment body 12 and then wound.

FIG. 5 shows another embodiment of the mounting structure of the auxiliary chute to the mixer car of the present invention, in which the mounting portion of the mounting tool 1 is fitted so as to match the auxiliary chute 2 bent into a rectangular shape. 11 and the back plate 3 are formed in a U shape, and the other configurations are the same as those in the above-described embodiment, the same reference numerals are given and the description thereof will be omitted.

[0014]

As is apparent from the above description, according to the attachment structure of the auxiliary chute to the mixer truck of the present invention,
Since the weight of the concrete is not concentrated on a part of the auxiliary chute, even if concrete is poured into the chute, the metal wire does not accidentally come off from the auxiliary chute.

Further, since the other end of the metal wire can be tied by hooking it on the hook portion of the other fitting, the auxiliary chute can be quickly attached and is suitable for a concrete pouring site. It becomes a thing.
