Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dust scattering prevention device for a garbage collection vehicle, and in particular, a scattering prevention plate is provided on the back side of an elevating panel so that dust can be prevented from rearward during shoveling 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 with a rear opening 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. This is a device in which a lifting panel, which is pivotally connected to the scraping panel, is moved almost vertically, and 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 causing injuries to workers. In order to prevent this, conventional practice has been 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 (for example, -49611)).

However, in this type of anti-scattering device, the rubber plate is directly fixed to the scraping panel, so when the elevating panel descends, bulky debris tends to get caught in the gap between the lower edge of the input port and the rubber plate, causing scraping. When the panel is rotated, the bulky debris may be caught in the panel when the panel is rotated.

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 may be caught in the gap between the top surface of the sump and the rubber plate. It may be rotated. As a result, the rubber plate is easily damaged, and as a result, there is a problem in that the rubber plate must be replaced frequently.
