Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small concrete plant truck for producing a small amount of green concrete or mortar on site in a small amount.

[0002]

2. Description of the Related Art Conventionally, when performing construction work that uses a small amount of fresh concrete or mortar on the site, such as setting road curbs and road signs, blocking work, gutter work, etc., transport a small amount produced at the factory to the site Since it is not possible, water, sand, gravel, and cement were usually mixed with a scoop at the site, or made using a small concrete mixer.

However, in the field work, in addition to transporting a small amount of material, water is carried in a tank, and then an iron plate is laid on the site and kneaded by hand on this, or a small concrete mixer is carried in. There is a problem that it takes a lot of time and labor to carry and work such as kneading and kneading, and the quality is not constant.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above problems and transports water and sand, gravel, cement and a small concrete mixer to the site at one time, so that fresh concrete or mortar of constant quality can be delivered on site. The present invention provides a concrete plant truck suitable for small-scale production.

It is characterized in that a concrete mixer, a loading platform for loading materials, and a water tank are integrally mounted.

A concrete plant carrier according to a second aspect of the present invention is characterized in that a loading platform for loading materials is formed by a dump which is tiltably supported by a cylinder. A concrete plant carrier according to a third aspect of the present invention is characterized in that the self-propelled traveling device is constituted by a crawler vehicle that travels by an engine.

Further, in the concrete plant carrier according to the present invention, the tank of the concrete mixer is mounted inside a substantially U-shaped support frame, and is rotatably supported by bearings provided on the left and right sides of the support frame. Thus, the tank can be rotated left and right with respect to the traveling direction.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG.
It will be described in detail with reference to FIGS. The concrete plant carrier 1 includes a small-sized concrete mixer 4, a dumper 7 in which a loading platform 5 for loading materials is tiltably supported by a cylinder 6, and a water tank 8 on a frame 3 of a self-propelled crawler vehicle 2. Are mounted, and the crawler wheel 2 is driven by the engine 9.

A small concrete mixer 4 is arranged in front of the engine 9 and, as shown in FIG.
A tank 13 is supported by 2A and 12B so as to be rotatable left and right. The tank 13 has a rotary shaft 14 projecting from the base end thereof, which is supported by a bearing 16 provided in the middle of a substantially U-shaped support frame 15 mounted so as to surround the tank 13, and further penetrates therethrough. The pulley 1 is attached to the tip of the rotating shaft 14
7A is attached. Further, a hydraulic motor 18 is attached to the support frame 15, and the pulley 1 is attached to the output shaft 19.
7B is attached and is connected to the pulley 17A by a belt 20 so that the tank 13 is rotated by the rotation of the hydraulic motor 18.

On both sides of the support frame 15 having a substantially U-shape, the bearings 2 provided on the upper portions of the stands 12A and 12B.
2 is supported by a support shaft 23 so as to be rotatable left and right. Further, as shown in FIG. 4, a large number of pin holes 25 are provided in front of and behind the support shaft 23 attached to the stand 12A side of the support frame 15.
The angle adjusting plates 26A and 26B, which are opened, are connected in the vertical direction.

Further, pin through holes 27A, 27 are provided in an upper portion of the stand 12A so as to face the angle adjusting plates 26A, 26B.
Brackets 28A and 28B having holes B are attached,
The lock pin 30 is pierced here, and the tip is angle adjusting plate 26.
By penetrating the pin holes 25 of A and 26B, the tank 13 is locked at a predetermined angle. Furthermore, the stand 12A of the support frame 15 having a substantially U-shape
The tip on the side is extended to form a rotation lever 32.

As shown in FIG. 2, the concrete plant carrier having the above-mentioned construction is such that the water tank 8 is filled with water and the dump truck 7 is used.
Place sand, gravel, and cement on the carrier 5 and transport them to the site by truck. When arriving at the site, the concrete plant carrier 1 is self-propelled and unloaded from the truck bed.
After this, self-propelled to the construction site, where as shown in FIGS. 3 and 4, the lock pin 30 is pulled out and the tank 13 is removed.
After changing the angle of the lock pin 30
Insert into the pin hole 25 of A to adjust the angle of the tank 13.

After that, the sand, gravel, and cement placed on the loading platform 5 are put into the tank 13, and an appropriate amount of water is poured from the water tank 8. After that, if a switch (not shown) is turned on to drive the hydraulic motor 18, as shown in FIG.
Power is transmitted through 7B, the belt 20, and the pulley 17A, and the tank 13 rotates to produce ready-mixed concrete or mortar. When ready-mixed concrete or mortar is manufactured, the lock pin 30 is pulled out from the pin hole 25 of the angle adjusting plate 26A, and the turning lever 32 is held in hand, and the tank 13 is turned downward to open its opening. Fresh concrete and mortar are discharged from the department.

Further, the dump 7 can carry not only the material but also the earth and sand and the like.
As shown in (3), by extending the cylinder 6, the bed 5 can be tilted and discharged at one time.

Therefore, when the construction using a small amount of fresh concrete or mortar such as the installation of curbs and road signs on roads, block construction, gutter construction, etc., all the necessary materials are used for the concrete plant carrier 1. Since it is loaded, it has excellent workability after going to the site and can be manufactured in a short time. Further, since the concrete plant carrier 1 can be driven by the crawler car 2, the concrete plant carrier 1 can also run on rough roads, slopes, and wetlands.

Further, in FIG. 2, the tank opening of the concrete mixer 4 is directed leftward in the traveling direction of the concrete plant carrier 1. However, depending on the work site, the rightward one is raw concrete as shown in FIG. There is also a convenient place to use or mortar.

In such a case, as shown in FIG. 4, when the lock pin 30 is pulled out from the pin hole 25 of the angle adjusting plate 26A and the rotary lever 32 is rotated in the arrow direction, both sides of the tank 13 are moved. The support shafts 23, 23 attached are the bearings 2.
Since it is rotatably supported by 2 and 22, it rotates about this point as the center of rotation to obtain the state shown in FIG. In this case, the tilt angle of the tank 13 is adjusted by adjusting the angle adjusting plate 2 shown in FIG.
6B pin hole 25, bracket 28B pin through hole 2
Insert the lock pin 30 through 7B to lock.

In the above description, the cargo bed 5 is composed of the dump 7 which is tiltably supported, but it may be a fixed cargo bed.
