Description

[Detailed Description of the Invention] This invention relates to a compactor for filling and storing garbage in a garbage storage container.

Conventionally, as a means for stuffing garbage into this type of container, a stuffing port opened in a lug gate of a container body is positioned opposite to a compression plate of a compactor main body, and both are fixedly connected to each other, and the stuffing port is At the same time as the locking is released, the inner lid that has been closed is moved and held by the compactor's compression platen, and the garbage thrown into the compactor body is packed into the container body by the compression platen's pushing operation. It is well known to have a structure in which the inner lid held by the compression plate is locked again to the filling opening of the container body to close it, thereby preventing dust from falling out.

However, with such a conventional structure, the holding mechanism between the inner lid on the container body side and the compression plate on the compactor body side, and the locking casing or release mechanism for the inner lid are complicated, unstable, and large. There were various problems, such as a high mechanical failure rate, high power consumption, and the tendency to generate noise due to rattling.

This invention is aimed at solving the above-mentioned conventional drawbacks, and will be explained below based on the illustrated embodiment.

As shown in FIGS. 1 to 5, reference numeral 1 in the figures is a container main body, a loading port 3 is opened in a rear gate 2, and a frame plate 4 is provided around the outer periphery of the container.

In the figure, reference numeral 5 denotes an inner cover that covers the filling port 3, and retaining holes 6 are formed on the upper left and right sides of the outer surface, and retaining holes 6 are provided on both the left and right sides of the frame plate 4. The lock pins 7 that engage with the lock holes 4a are provided at two upper and lower positions, and each of the lock pins 7 is
is pinioned to a pair of connecting rods 8 arranged on the left and right, and protrudes into engagement with the lock hole 4a side by the biasing force of a spring 9, making it possible to lock.
By pulling the connecting rod 8 inward (in the direction of the solid arrow in FIG. 2), it sinks against the biasing force of the spring 9, releasing the locking state and making it possible to separate.

Reference numeral 10 in the figure denotes a notch recessed in the center of the lower surface of the inner lid 5, which is connected to the lower surface of the frame plate 4 forming the filling port 3 via a spring 12 when the inner lid 5 is in the locked state. It engages with a guide lever 11 which is biased so as to be able to rotate upright, thereby preventing the inner lid 5 from swinging laterally.

Furthermore, 13 in the figure is a compactor body to which the rear gate side of the container body 1 faces and is fixedly connected, and a drive device such as a hydraulic cylinder is located at a position corresponding to the filling port 3 opened in the rear gate 2 of the container body 1. At 14, a pushing mechanism consisting of a compression plate 15 that is movable in the front-rear direction inside the inner cylinder 13a is installed, and the pushing mechanism pushes the garbage thrown in from the hopper 16 into the front side of the wheel plate 15, thereby forming the container.
It is designed so that it can be stuffed inside.

Further, on the front surface of the compression plate 15, there is an engaging pin 17 that protrudes to correspond to the retaining hole 6 of the inner cover 5, and a connecting rod 8 that moves the lock pin 7 of the inner cover 5. An inner lid holding mechanism is provided which includes a pair of left and right lock hooks 18 that are engaged with each other, and a hydraulic cylinder 19 that rotates the lock hooks 18 in the horizontal direction by their extension and contraction operations.

Note that 20 in the figure is a stopper member that restricts the rotation of the lock hook 18.

That is, as shown in FIGS. 6 to 8, in the inner lid holding mechanism, when the container body 1 is fixedly connected to the compactor body 13, the compactor inner cylinder 13a moves the guide lever 11 by the spring 12. When the compression board 15 is collapsed against the biasing force (see Fig. 6) and the engagement pin 17 protruding from the front surface of the compression plate 15 is inserted into the engagement hole 6 of the inner lid 5 in the locked state on the side of the container body 1. At the same time, the locking hook 18 is engaged with the movable connecting rod 8 of the lock pin 7 of the inner cover 5, and the locking hook 18 is rotated in the direction of clamping the connecting rod 18 by the contraction operation of the hydraulic cylinder 19, thereby locking. After the inner cover 5 is moved and held in front of the compactor body 15 (see FIG.
After the garbage thrown into the container is allowed to fall and accumulate in front of the compression plate 15, the compression plate 15 is moved forward again toward the filling port 3 of the container body 1 (see Fig. 8), and the garbage is compressed into the container. It is pushed into the main body.

Therefore, according to the above configuration, an inner lid holding mechanism consisting of a hydraulic cylinder, a lock hook, and an engagement pin is provided on the front part of the compression plate forming the pushing mechanism of the compactor body, and the inner cover is secured to the compactor body by the holding mechanism. Since the inner lid attached to the loading port of the connected container body is moved and held on the compression plate side at the same time as the locking is released, the inner lid can be removed during garbage filling and the container body after filling. Closing the filling port can be done easily and automatically, and the mechanism is very simple, causing fewer troubles.

In addition, the inner lid that closes the filling port of the container body is provided with a notch, and the guide lever is engaged with the notch when the lid is closed, so that the inner lid can be closed during transportation. This has excellent practical effects, such as less rattling and easy alignment to the compression plate that is moved and held when connected to the compactor main body.
