Description

[Detailed Description of the Invention] Conventionally, in the concrete industry, a rotating gear type special packet 1 as shown in FIGS. 1 and 2 has been used for transporting and charging fresh concrete.

In addition, in the figure, 2 indicates a rotating device, and 3 indicates a rotation center.

Further, 1' indicates the rotational position of packet 1.

However, in the case of a rotating gear type packet as shown in Figures 1 and 2, the center of rotation is firstly at the center of the car body, and packet 1 can only turn around the center of the car body, so when discharging fresh concrete, There was a limit to its reach.

In addition, when removing fresh concrete remaining at the edge of the packet, the final scooping operation is not easy, and the remaining material may not be completely removed, or depending on the degree of mixing of the ready-mixed concrete, it may remain at the edge of the packet and fall back to its original state. I had something to go back to.

However, solving this problem requires high rotational torque, and in the worst case, there is a risk of damage to the rotating gear section.

In this case, it would be sufficient to make a large-capacity rotating gear device, but
In this case, the load center loss was large, and the weight and shape were large, which caused problems.

The present invention was proposed in order to eliminate the above-mentioned drawbacks of the conventional technology. By moving the center of rotation to the right and left to increase the reach, it is possible to absorb high rotational torque and prevent the sagging at the tip of the packet. It is an object of the present invention to provide a side dump packet device that can be operated quickly, and is labor-saving.

The embodiment of the present invention will be explained below with reference to the drawings. Figs. 3 to 5 show the installed state of the side dump packet device showing the embodiment of the present invention, and Fig. 3 is a partially cutaway plan view, and Fig. FIG. 4 is a front view, and FIG. 5 is a side view.

Note that the lateral direction described below is the direction seen from the fork insertion direction.

In the figure, 4 is a fork, 5 is a frame, and sheaths 6 and 6' into which the fork 4 is inserted are located on the left and right sides of the frame 5, respectively.
A plate 8 holding a packet rotation support pin 7 is fixed to the left sheath 6 by welding or the like.

In addition, a plate 1 for holding a pin 10 supporting the base end of the dump cylinder 9 is provided at the center inside the left sheath 6.
1 is fixed by welding or the like.

On the other hand, a guide plate 13 of the packet 12 is fixed on the right sheath 6' by welding or the like.

Further, the packet 12 is pivotally attached to the frame 5 via a plate 14 and a pin 7 fixed to the lower left side thereof.

Further, a plate 15 is fixed to the right side of the lower center of the packet 12, and the plate 15 and the piston rod 9a of the dump cylinder 9 are rotatably connected via a pin 16.

Further, a stopper plate 17 that engages with the guide plate 13 is fixed to the packet 12.

Next, to explain the operation, the counterclockwise rotation state of the packet 12 shown in FIG. The state becomes 12', which is indicated by a chain line.

Also, packet 12' in a rotating state is indicated by a solid line.
When returning to state 2, by retracting the piston rod 9a of the dump cylinder 9, the packet 12 is rotated and the stopper plate 17 is inserted between the guide plates 13, thereby performing stable return and positioning in the rotational direction. .

Note that the insertion direction of the fork 4 into the sheaths 6, 6' is as follows:
If the direction is reversed to that shown in FIG.
If it is rotated around the pin 7, it will rotate to the right, making it easy to switch between left and right rotation.

Since the present invention is constructed as explained in detail above,
By switching the insertion direction of the forklift fork,
Since it is easy to switch between left and right rotation of the packet, and unlike conventional packet devices, the center of the packet is not used as a fulcrum, it is possible to increase the left and right reach.

In addition, it has a simple structure, can absorb high rotational torque, makes the final shakuri work easy, saves labor, and has extremely excellent practical effects that fully meet the needs of the concrete industry. be.
