Description

[Detailed description of the invention] Industrial application field The present invention relates to a simple earth and sand loading device, and more specifically, the purpose is to collect and load roof soil onto a truck and transport it when re-roofing roof tiles, for example. This relates to a simple earth and sand loading device used in

Conventional Technology Conventionally, when replacing roof tiles in a general household, a tile roofer would climb onto the roof of the house and remove one old tile each time to avoid causing unnecessary damage to the house. Each piece is manually peeled off, placed on the ground, and then transported to a landfill or other location for disposal.

After peeling off the old tiles, a large amount of dry roof soil is generated, which is also peeled off with a scoop so as not to damage the roof foundation, lowered to the ground, and then transported to a landfill or other site for disposal.

The above work is difficult to mechanize because it is carried out on a small scale by each household, and to avoid inadvertently damaging other parts of the house, the foundation of the roof, etc., and is usually done manually by workers. depends on.

Problems that the invention aims to solve The above roofing soil is generally very dry, and when it is peeled off from the roof and placed on the ground, it creates a large amount of dust and causes a great deal of nuisance to neighboring homes, against the wishes of the owner. In addition, the work environment and work efficiency were not good either.

It may seem like it would be fine to sprinkle water before removing the roof soil, but if you do this, the roof soil will become viscous and stick to the roof shingles that form the foundation of the roof, making removal work more troublesome. It will become.

Means for Solving the Problems The present invention is equipped with an exhaust/drainer 7, a vacuum pump 8, and a dedicated engine 9 for driving the vacuum pump 8, and the vacuum pump 8 drives the flow through the exhaust/drainer 7. A self-propelled vacuum pump suction vehicle 2 that generates air intake at an inlet 12, a cargo box 3 with an open top, and a substantially rectangular roof covering the top opening, with a lower periphery formed into a cargo box. 3 is airtightly fitted and placed on the periphery of the upper opening of the vacuum pump suction wheel 2 via a sealing material, and can be attached and detached using a clamp fitting. The material to be treated storage box 14 is constituted by the airtight lid 4 which has an air intake connection port 6 connected to the air intake port 6 and the airtight lid 4 which has an earth and sand suction port 5 in the center of the upper surface, and the material storage box 14 is mounted on the vehicle body frame. The inlet 12 of the exhaust/draining device 7 of the vacuum pump suction vehicle 2 and the air outlet 16 of the workpiece storage box 14 of the workpiece loading vehicle 1 are used to draw air. In addition to connecting with a hose 13, a dirt suction nozzle 1 is connected to the dirt suction port 5 of the processing object storage box 14 at the tip.
This is a simple earth and sand sanctioning device to which a earth and sand suction hose 11 having a diameter of 0 is connected.

Function: The present invention allows a vacuum pump suction vehicle to be dispatched to the work site carrying a sealing lid, and by attaching the sealing lid airtightly to the cargo box of a normal dump truck and driving the vacuum pump. Roof soil can be loaded into the cargo box with high efficiency without scattering dust nearby, and when the box is fully loaded, the sealing lid is removed and only the dump truck is sent to a landfill or the like.

Embodiment Hereinafter, the configuration and operating procedure of the device of the present invention will be explained based on an example of roof soil collection and transportation work shown in the drawings. Reference numeral 1 designates a vehicle loading objects to be treated, for example roofing soil, and reference numeral 2 designates a vacuum pump suction vehicle. The loading box 3 of the roofing soil loading vehicle 1 generates the negative pressure suction force necessary to suck and store the roofing soil into the container body when the airtight lid 4 is attached to the top opening. It is formed into a sealed structure using a known sealing member so that it can maintain higher airtightness than the loading platform. A sealing lid 4 is removably attached to the top opening of the packing box 3 using an appropriate clamp fitting such as a bolt type.
A dirt suction port 5 is opened in the center of the top surface, and an air intake connection port 6 is opened in the top surface of the sealing lid 4 located in front of the dirt suction port 5. On the other hand, the vacuum pump suction vehicle 2 is equipped with an exhaust/drainer 7, a vacuum pump 8, and a dedicated engine 9 separate from the traveling engine that drives the vacuum pump 8. The earth and sand suction port 5 of the object loading vehicle 1 is connected to a earth and sand suction hose 11 having a sand suction nozzle 10 at its tip for sucking roof soil. It communicates with the inlet 12 of the exhaust/drainer 7 via an intake hose 13.

In order to operate the earth and sand collection and transportation vehicle according to the present invention, first, the dedicated engine 9 is started, and the vacuum pump 8 is operated by the dedicated engine 9 to operate the exhaust/drainer 7, the intake hose 13, the cargo box 3, and the sealing lid 4. A negative pressure suction force is generated in a negative pressure suction mechanism constituted by the earth and sand storage box 14, the earth and sand suction hose 11, and the earth and sand suction nozzle 10.

In order to store the roofing soil 18 laid under the tiles 19 of the retiled roof into the soil storage box 14 of the object loading vehicle 1, a worker uses a ladder 17 as shown in FIG. 15 climbs onto the roof, brings the soil suction nozzle 10 attached to the tip of the hose 11 held by the holder 16 close to the surface of the roof soil 18, and applies the negative pressure suction force of the negative pressure suction mechanism. Therefore, the roof soil 18 is suctioned, and the suctioned roof soil 18 is stored in the soil storage box 14.

Effects of the Invention The present invention allows a sealed earth and sand storage box to be easily and quickly formed on site by removably attaching a sealing lid to the top opening of a general-purpose truck loading box. In this way, trucks normally used for transporting cargo can be easily used as tank cars for loading and transporting earth and sand, and can be used for scraping roof soil and loading it onto trucks during roof tile re-roofing work. can be carried out with high efficiency and without scattering dust in the vicinity. In addition, the present invention connects a vacuum pump to the downstream side of the earth and sand storage box (viewed from the direction of air flow and movement of earth and sand) via an exhaust and drain device, and connects the vacuum pump to the vacuum pump suction vehicle. By being driven by a dedicated engine that is completely separate from the driving engine, the negative pressure suction mechanism generates negative pressure for soil collection, so moisture contained in the atmosphere is removed by the exhaust and drainage device. The water is then discharged out of the system, and no water enters the vacuum pump at all. Therefore, the vacuum pump can maintain a good level of negative suction power for earth and sand, and can maintain stable working conditions over a long period of time without rusting due to adhesion of moisture.
