Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compactor/container in which bulky compressible waste such as garbage is compressed and forced into the container.

In conventional compactors, the extrusion port of the compactor main body is connected to the inlet of the container, and a pushing plate in the compactor main body is operated to compress the waste and push it into the container to fill it, as shown in Fig. 4. Since the pushing operation is performed by connecting the lid d that closes the entrance C of the container b to the pushing surface on the front surface of the pushing plate a by the securing mechanism e, the compressed garbage does not recur during this operation. The lashing mechanism e may be unexpectedly released due to force, impact force, or dirt getting caught, and the lid body d may come off and be left inside the container b as shown by the two-dot chain line. If you disconnect the push plate a, the push plate a may be deformed or the push plate a may be damaged through the attachment part of the lashing mechanism e.
There is a risk that dust may get mixed into the back side, causing damage to the device or malfunction.

In view of the above, the present invention is a compactor with a simple structure, which detects when the pushing surface of the pushing plate and the lid separate, and prevents the intrusion of dirt, thereby eliminating the above-mentioned risk.・The purpose is to provide containers.

Hereinafter, a first embodiment of the present invention will be described with reference to FIG. 1. A is a compactor, the main body 1 of which has an extrusion port 2 in its front face and an input port 3 in the front part of its upper wall. A hopper 4 is formed integrally with the compactor body 1 above the input port 3.

A pushing plate 5 is housed in the compactor body 1 so as to be able to slide back and forth, and this pushing plate 5 has a pushing surface 6 formed on its front surface, and the input port 3 is opened and closed on its upper surface. A possible shielding surface 7 is formed.

A hydraulic cylinder 8 is connected between the back surface of the pushing plate 5 and the rear wall of the compactor body 1, and the pushing plate 5 can be slid back and forth by the expansion and contraction operation of the hydraulic cylinder 8.

The shielding surface 7 of the push-in plate 5 extends forward from the push-in surface to form an eaves piece 9, and this eaves piece 9 connects the push-in surface 6 and a container B, which will be described later, to be joined and connected thereto. Lid body 1
The upper surface of the joint with 0 can be covered.

The lid 10 of the container B is detachably connected to the pushing surface 6 of the pushing plate 5 by a lashing mechanism L, that is, the lid 10 of the container B is connected to the pushing surface 6 of the pushing surface 6 in the lateral direction. Several fitting grooves 11 are formed, and these fitting grooves 1
Several horizontally extending protrusions 12 formed on the lid 10 of the container B are fitted into the container B.

Several brackets 13 are provided on the back side of the pushing surface 6 of the pushing plate 5.
are integrally provided, and lashing claws 14 are pivotally supported 15 on these brackets 13 so as to be able to rotate up and down, and each lashing claw 14 can engage with the lid body 10 by its own weight. ing.

A gate 18 is pivotally supported 19 on the open end surface of the container B so as to be freely openable and closable, and an inlet 20 having approximately the same size as the extrusion port 2 of the compactor A is opened in the gate 18. can be closed by the lid body 10 connected to the push-in surface 6 of the push-in plate 5 as described above, and the insertion hole 21 bored in the gate 18 and the lid body 10
The lid body 10 can be bar-tacked to the entrance 20 by passing a bar-tacking rod (not shown) through the insertion hole 22 formed in the opening 20 .

The fitting groove 11 of the pushing surface 6 and the lid 10 of the container B
A proximity switch 23 serving as a detection means is disposed at a distance from the surface facing the protrusion 12 .

The proximity switch is in an inactive state when the pushing surface 6 and the lid body 10 are connected, and is in an operating state when they are separated during the pushing process, and is connected to an appropriate alarm device, safety device, etc.

Next, the operation of one embodiment of the present invention will be described. In a state where the lid body 10 is currently bar-tackled to the entrance 20 of the gate 18 of the container B by the bar-tacking rod, the hydraulic cylinder 8
When the pushing surface 6 of the pushing plate 5 is joined to the lid body 10 by being extended, the tips of the lashing claws 14 are fitted into the lid body 10.

When the bar tacking is removed, the lashing pawl 14 engages with the locking piece 16 due to its own weight, and the lid 10 is separated from the inlet 20 and simultaneously secured to the pushing surface 6 of the pushing plate 5. be done.

At this time, the proximity switch 23 disposed on the push-in surface 6 and the lid body 10 is in the proximity position, so it is set to be interlocked with an appropriate alarm device or the like.

When the hydraulic cylinder 8 is contracted in this step, the push plate 6 is moved back from the input port 3 together with the lid 10, and the hopper 4 is moved back.
The waste inside falls into the compactor body 1.

Next, by extending the hydraulic cylinder 8, the pushing plate 5 moves forward and pushes the waste into the container B through the pushing outlet 2 and the inlet 20 while the lid 10 is connected to the pushing surface 6. can.

By repeating the expansion and contraction of the hydraulic cylinder 8, the pushing plate 5 can reciprocate and compress the waste into the container B. However, if the pushing surface 6 and the lid 10 separate at that time, Since the proximity switch 23 is activated and the operator of the compactor/container is notified by activation of an alarm or the like, it is sufficient to stop the apparatus and secure the lid 10 to the pushing surface 6 again.

FIG. 2 shows a second embodiment of the present invention, in which a limit switch 2 is installed on the push plate 5 instead of the proximity switch as a detection means.
4, the lid body 10 is provided with a dog 25, which is connected to a suitable alarm device, safety device, etc., and the operation is the same as that of the first embodiment.

FIG. 3 shows another embodiment of the lashing mechanism L, in which an electromagnet 26 is attached to the front end of the pushing plate 5, and an electromagnetic force is generated on the pushing surface 6 to join the lid body 10. Naturally, it can be used in combination with a detection means.

As described above, according to the present invention, since the detection means is provided at the joint between the pushing plate and the lid in the compactor container, even if the lid suddenly comes off during the pushing operation, the lid will remain inside the container. There is no need to leave the device unattended, and damage and failure of the device, such as the pushing plate, can be prevented.
