Abstract

PURPOSE:To automatically detect whether or not refuse is discharged out as well as to prevent a detector from being damaged and stained by providing a detecting plate which is rocked as a housing box is tilted, for a refuse housing box, and thereby preventing the detector from being blocked by refuse by means of the detecting plate. CONSTITUTION:A detecting plate 13 which is rocked toward a rear opening section 5 when a housing box is tilted, is provided for the forward inner surface 2a of the housing box 2. The detecting plate 13 is formed in such a way that the upper section of its metallic plate member is rotatably connected to the forward inner surface 2a by a hinge 14. This thereby permits the detecting plate to be rocked while its lower end is separated from the forward inner surface 2a when the housing box 2 is tilted, and also permits the plate to abut against the forward inner surface 2a so as to block a hole 15 formed in the forward inner surface 2a when the housing box 2 is in a normal position. In addition, the hole 15 blocked by the detecting plate 13 is provided with a detector 17 at the forward section of the housing box 2 to detect the rocking motion of the detecting plate 13. This thereby causes the detecting plate 13 to block the detector 17, the detector 17 is thereby prevented from being damaged and stained even if refuse is packed in the housing box 2 with pressure.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a garbage collection vehicle, and particularly to a structure for detecting the discharge of garbage from a garbage storage box.

(Prior art and its problems) As a garbage collection vehicle, a garbage storage box having an opening at the rear is provided on the running vehicle so that it can tilt using the lower part of the rear end as a fulcrum, and the garbage stored in the garbage storage box is transferred to the storage box. Some are designed to be ejected by tilting.

Conventionally, in the above-mentioned garbage collection vehicle, it has been generally determined whether or not garbage has been discharged from the storage box by visual inspection by the operator. This has the problem of increasing work efficiency and reducing work efficiency.

In addition, as a method for automatically detecting garbage discharge, a method has been considered in which a photoelectric sensor is installed near the opening of the storage box and the movement of garbage discharge is detected by the sensor. Since the sensor is exposed inside the storage box, the detection section is likely to become dirty or damaged by the stored garbage, making it impossible to perform reliable and reliable detection.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a garbage collection vehicle that is free from damage or malfunction caused by the garbage it accommodates and is capable of reliably detecting garbage discharge.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention attaches a detection plate to the front inner surface of the garbage storage box that swings toward the rear opening when the storage box is tilted, and when the storage box is not tilted, the detection plate The structure is such that a detector is provided on the inner surface of the front part of the storage box to be closed, to detect the swinging of the detection plate.

[Effect]

In the above structure, when the garbage storage box is tilted and the garbage inside is discharged, the detection plate swings, and the detector detects the swing to confirm that the garbage has been discharged.

Furthermore, when garbage is stored in the garbage storage box, the detection plate closes the detector, thereby preventing the detector from being damaged or soiled.

〔Example] Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in FIGS. 1 and 2, the garbage collection vehicle consists of a traveling vehicle 1 and a garbage storage box 2 loaded thereon. It is installed so that it can be tilted up and down. Here, 4 is a dump cylinder for tilting the housing N2.

The garbage storage box 2 is formed as a closed container with only an open rear part, and a tailgate 7 is rotatably attached to the upper end of the rear opening 5 via a bin 6.

This tailgate 7 has a garbage input port 8 on the rear surface, and is provided with a garbage loading device 9 that includes a rotary plate 10, a push plate 11, etc. for pushing the garbage input from the garbage input port 8 into a storage box. ing.

Reference numeral 12 in the figure is a driving cylinder that rotates the tailgate 7.

On the other hand, the front inner surface 2a of the storage box 2 is provided with a detection plate 13 that swings toward the rear opening 5 when the storage box is tilted.

As shown in FIGS. 3 and 4, this detection @ 13 is formed by connecting the upper end of a metal plate rotatably to the front inner surface 2a by a hinge 14, and when the storage box 2 is tilted. The lower end swings away from the front inner surface 2a, and when the housing 2 is in a normal state, it comes into contact with the front inner surface 2a and closes the hole 15 formed in the front inner surface. In addition, 1
6 is a member for ensuring that the detection plate 13 closes the hole 15.

In addition, in the hole 15 that is covered by the detection plate 13 described above, a detection 81 is attached to the front part of the storage box 2. The detection unit is facing the camera.

This detector 17 uses a screw-in type proximity switch, and the detection plate 13 swings to cover the front inner surface 2 by a predetermined distance.
It is activated when the driver leaves the vehicle 1, and an indicator 18 such as a buzzer or an indicator light provided in the driver's seat of the vehicle 1 is activated.

The garbage collection vehicle of the embodiment has the above-mentioned configuration, and the first
As shown in the figure, when the storage box 2 is in a horizontal state, the detection plate 13 blocks the detector 17, so even if the garbage is stored in the storage box 2 in a compressed state, the detector 17 will not be damaged or dirty. Prevented.

On the other hand, as shown in FIG. 5, the storage box 2 is tilted and the rear opening 5
When the dust is discharged from the machine, the detection plate 13 swings, the detector 17 detects this, and the operator is informed that the dust has been discharged.

In the above case, even if the storage box 2 is tilted, if the garbage pushed in in the compressed state at the back of the storage box remains in the storage box due to the bridging phenomenon and is not discharged, the detection plate 13 is stopped by the garbage. Since the sensor does not swing, the detector 17 does not operate.

In other words, detector 1 is activated only when the dust has been completely discharged.
7 is activated, so you can reliably confirm that the garbage is being discharged.

In this embodiment, a garbage collection vehicle is shown in which a tailgate 7 having a rotating plate-type garbage loading device 9 is provided at the rear of the storage box 2, but a loading device such as a garbage collection vehicle having a compression plate-type loading device Even if the garbage collection vehicle has a different structure, the structure of the present invention can be applied as long as the garbage collection vehicle has a structure in which garbage is discharged by tilting the storage box.

Further, the detector for detecting the swinging of the detection plate is not limited to a proximity switch, and a contact type sensor or other position detection sensor can be used.

〔Effect of the invention〕

As explained above, in this invention, the garbage storage box is provided with a detection plate that swings due to the tilting movement of the garbage storage box, and the detection plate blocks the detector from the garbage, so that it can be determined whether or not garbage has been discharged. In addition to being able to detect automatically, it is possible to prevent damage and dirt on the detector, and has the effect of reliably and stably detecting garbage discharge.
