Description

Detailed Description of the Invention A. 1. Purpose of the Invention (1) Industrial Field of Application The present invention relates to a device for preventing a push-down plate from falling off, which is mounted on the front face of a push-in ram in a compactor container.

(2) Conventional technology In a compactor container in which waste such as dust and the like thrown into the interior by a conventional compactor is pushed into a container and filled, a lid plate that shields the entrance and exit of the container is provided on the front side of the compactor ram. A structure in which the plates are connected to be used as a pushing plate for waste is known (see Japanese Patent Publication No. 57-59163).

(3) Problems to be Solved by the Invention In general, in a compactor container, the container is integrally connected to the compactor, the outlet of the container is communicated with the outlet of the compactor, and the pushing ram of the compactor enters the container through the inlet and outlet of the container. The waste that has been thrown into the compactor is pushed into the container while being compressed.In such a compactor container, when separating them, the inlet and outlet of the container are closed by the lid plate, and when connecting them, The lid plate is removed from the entrance / exit of the container, and is secured to the front surface of the pushing ram of the compactor by a fastening mechanism so that the lid plate can be used as the pushing plate of the pushing ram.

However, when the lid plate, that is, the pushing plate is fastened to the front surface of the pushing ram, if the fastening mechanism does not operate properly due to some reason, the vibration or impact acting on the ram accompanying the forward / backward movement of the pushing ram is generated. Therefore, there is a problem that the pushing plate falls off from the pushing surface of the ram, which hinders the pushing operation or damages each part of the compactor container.However, in the conventional device, such a fastening mechanism is ineffective. It was not assumed that the pushing plate would fall off the pushing surface at all, and no special measures were taken to avoid such a situation.

The present invention has been proposed in view of such circumstances, and even if the fastening mechanism does not operate properly, the pushing plate is locked to the pushing surface of the pushing ram so that the pushing plate is accidentally detached from the pushing surface. An object of the present invention is to provide a device for preventing the push-in plate from falling off in a compactor container, which is not performed.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention relates to a compactor and a container by connecting an outlet opening on the front surface of a compactor body to an inlet / outlet opening on one end wall of the container. The push ram, which is slidably provided in the compactor body, is detachably fastened to the push face of the push ram that shields the entrance and exit of the container through the fastening mechanism, and the push ram reciprocally slides. In a compactor / container in which the waste in the compactor body is pushed into the container by movement, between the ram guide integrally projecting on the pushing surface and the recess provided in the pushing plate corresponding to the ram guide. Further, even when the fastening mechanism is ineffective, if the ram guide is in the state of being received in the concave portion, the ram guides are locked to each other to prevent the pressing plate from falling off the pressing surface. Characterized in that provided.

(2) Operation According to the above configuration, when the pushing plate is fastened to the pushing surface of the pushing ram in the compactor container, even if the fastening mechanism does not operate for some reason, the ram guide of the pushing plate pushes. If they are received in the recesses of the plate, they can be locked to each other by the locking mechanism and the pressing plate can be accurately held on the pressing surface side of the pressing ram. Therefore, even if vibration or impact is applied to the pushing plate as it moves forward or backward, the pushing plate is effectively prevented from falling off the ram pushing surface.
