Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a garbage scattering prevention device for a garbage collection vehicle, and in particular, a scattering prevention plate is provided on the back side of a raking panel so that garbage can be prevented from rearward during raking or pushing operations. This invention relates to a dust scattering prevention device for a garbage collection vehicle that can prevent dust from scattering to other places.

[Conventional technology]

Generally, a garbage collection vehicle has a garbage storage box opened at the rear mounted on the vehicle body, and a tailgate with a built-in loading device is attached to the rear opening of the garbage storage box. Various types of loading devices are used, but the loading device to be solved by the present invention is called a centerless method, and is a loading device suitable for collecting bulky garbage. It is. In this type of device, the lifting panel, which is rotatably connected to the scraping panel, can be moved up and down.In this type of device, debris is collected from the input port during the scraping or pushing operation that compresses and crushes the garbage. There were safety issues such as the particles scattering outside and injuring workers. In order to prevent this, it has been conventionally done to close the gap between the sump and the tip of the raking panel by fixing a rubber plate to the back surface near the lower end of the raking panel. (See Publication No. 49611). However, in this type of anti-scattering equipment, the rubber plate is directly fixed to the scraping panel, so when the elevating panel descends, bulky debris is likely to get caught in the gap between the lower edge of the input port and the rubber plate. When the scraping panel is rotated, it may be rotated with the above-mentioned bulky debris being caught. Also, when the scraping panel is rotated, bulky debris may protrude from the gap between the tip of the scraping panel and the top surface of the sump, and this bulky debris is caught in the gap between the top surface of the sump and the rubber plate. It may be rotated. Therefore, the rubber plate is easily damaged, and there is a problem in that the rubber plate must be replaced frequently.

[Problem that the invention seeks to solve]

Therefore, an object of the present invention is to prevent debris from scattering to the outside from the input port when the scraping panel is rotated or pushed in, and also to prevent large debris from being caught in the gap between the scattering prevention plate and the top surface of the Nobu 1 during scraping. To provide a dust scattering prevention device for a garbage collection vehicle, which prevents dust from scattering.

(Means for Solving the Problems) In order to achieve the above object, the present invention incorporates a vertically movable elevating panel into the tailgate whose upper end is pivotally connected to the opening of the garbage storage box. In a garbage collection vehicle in which a scraping panel is rotatably pivoted to the lower edge of the panel, the upper end of a scattering prevention plate is pivoted to the rear side of the scraping panel, and the scattering prevention plate and the rear side of the lifting panel are connected together. It is characterized by being pin-coupled with a connecting link, and when the scraping panel performs a scraping operation, the scattering prevention plate can be held at a position away from the back surface of the scraping panel via the connecting link.
