The loading mechanism of the aforementioned packer truck has a lifting plate that lifts the garbage to a position where it can be pushed in. The cleaning method according to claim 3, wherein in the second step, the tip of the lifting plate is located at the lower end of the input port.
The cleaning method according to claim 5, wherein the second step further includes an inner bottom cleaning step of cleaning the inner bottom by spraying a cleaning solution onto the inner bottom from the second nozzle.
The cleaning method according to claim 2, wherein the spray angle of the first nozzle is wider than the spray angle of the second nozzle.

Description

This invention relates to a cleaning method for cleaning a garbage truck using a cleaning device. For example, Patent Document 1 discloses a cleaning device for a garbage truck that cleans the inside of a hopper for loading garbage and a garbage container that holds the garbage loaded from the hopper. Japanese Unexamined Patent Publication No. 57-158148 This is a perspective view showing an overview of the cleaning apparatus according to Embodiment 1 of the present invention.This is a perspective view showing an overview of the cleaning apparatus according to Embodiment 1 of the present invention.This is a plan view of the cleaning unit according to Embodiment 1 of the present invention, as seen from above.This figure shows the cleaning unit according to Embodiment 1 of the present invention in a rotating state.This flowchart shows an example of a cleaning method according to Embodiment 1 of the present invention.This figure shows an example of an operation panel provided in a control device according to Embodiment 1 of the present invention.This figure illustrates each step of the cleaning method according to Embodiment 1 of the present invention.This figure illustrates each step of the cleaning method according to Embodiment 1 of the present invention.This figure illustrates each step of the cleaning method according to Embodiment 1 of the present invention.This figure illustrates each step of the cleaning method according to Embodiment 2 of the present invention.This figure illustrates each step of the cleaning method according to Embodiment 2 of the present invention. [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail. First, in this embodiment, the cleaning device 100 for cleaning the packer truck 7 will be described with reference to Figures 1 and 2. Figures 1 and 2 are perspective views showing an overview of the cleaning device 100. For the sake of explanation, the vertical direction, the front-rear direction, and the left-right direction are defined as indicated by the arrows in Figure 1, etc. The front direction is the direction in which the packer truck 7 to be cleaned is parked relative to the cleaning device 100. The front-rear direction is the vehicle length direction of the packer truck 7, the left-right direction is the vehicle width direction of the packer truck 7, and the vertical direction is the vehicle height direction of the packer truck 7. In this embodiment, the vertical direction is perpendicular to the front-rear direction and the left-right direction, and the front-rear direction is perpendicular to the left-right direction. The garbage truck 7 is a so-called waste collection vehicle, and its chassis is equipped with a storage box 70X and an input box 70Y. The storage box 70X is an example of a storage section according to this disclosure, and the input box 70Y is an example of an input section according to this disclosure. The rear opening of the storage box 70X and the front opening of the input box 70Y are in communication. The upper part of the input box 70Y is pivotally supported relative to the storage box 70X and can tilt relative to the storage box 70X. The garbage truck 7 cleaned by the cleaning device 100 may be, for example, a press-type garbage truck or a rotary-type garbage truck. Details of the press-type garbage truck and the rotary-type garbage truck will be described later. (Overview of the cleaning equipment) The cleaning device 100 includes a cleaning unit 10 that extends along the left-right direction (vehicle width direction) and has a plurality of nozzles for spraying cleaning fluid along this extension direction. Details of the cleaning unit 10 will be described later. The cleaning unit 10 is rotatable about a rotation axis that extends along the vehicle width direction and is movable in the vehicle length direction. For example, the cleaning unit 10 may be attached to a pair of guide rails 20 as shown in Figures 1 and 2. A pair of guide rails 20 extend along the front-rear direction and guide the movement of the washing unit 10 in that direction. The pair of guide rails 20 are supported by a plurality of support columns 21 and are positioned at a distance from the installation surface (ground) on which the washing device 100 is installed. The pair of guide rails 20 may be positioned below the top surface of the housing box 70X in the vertical direction. The pair of guide rails 20 may be positioned, for example, at a distance of approximately 150 cm from the installation surface. If the side of each guide rail 20 facing the washing unit 10 is open, an overhang-like cover may be provided on the open side to reduce the accumulation of debris scattered during car washing inside the rail. By using an overhang-like cover, maintenance work such as applying grease to the chain or removing debris inside the guide rail 20 is improved compared to providing a cover that closes the open side. The pair of guide rails 20 are in
