Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a garbage collection device, particularly for use in sandy beaches near the coast,
The present invention relates to a coastal trash collection device that can separate and collect trash such as trash existing at the beach, on the sea surface in shallow waters, under the sea, and on the seabed from sea sand and sea water.

[Conventional technology] Conventionally, the efficient collection of garbage such as garbage scattered on the shoreline has relied on manual labor, and at the same time, cleaning work has been carried out to clean up the garbage that has accumulated in the ocean and on the seabed. In such cases, a suction pump was installed on the recovery boat, a recovery pipe connected to the pump was submerged in the water, and the debris from the water bottom was sucked up along with sand and water onto the boat through the suction port at the tip of the pipe. Then, on board the ship, the garbage was sieved, the murky water was dumped into rivers and the sea, and the sand and garbage were separated, so that only the garbage was collected and disposed of.

[Problem N to be Solved by the Invention] However, in the conventional method, because murky water is dumped into a river or the like, there is a problem in that the dumping water area is diffused and polluted, causing destruction of nature. Furthermore, conventional collection equipment not only requires a large pump, but it is also difficult to collect only dust from sand and water, and the equipment must be installed separately from the suction equipment to sieve sand and dust. , there was also the problem of a large burden on equipment.

The present invention focuses on the above-mentioned conventional problems, and provides a garbage collection device with a structure that can collect only garbage directly from the bottom of the water with a simple equipment configuration without causing water pollution.
At the same time, the purpose of the present invention is to provide a garbage collection device that can also process and recover garbage from the land portion of the coast, that is, from sandy beaches and beachfronts.

[Means for Solving the Problems] In order to solve the above problems, one aspect of the present invention is a coastal garbage collection device.

A garbage collection unit consisting of a box consisting of an operator's cab, an equipment room, a garbage storage chamber, and a power chamber; a garbage storage tank having a bar screen with a rake or a mesh screen with a rake and a bottom plate that can be opened and closed; a water flow generator for introducing seawater into a bar screen or a mesh screen with a rake; a stirring rake disposed in front of the lower end of the bar screen with a rake or a mesh screen with a rake; and a lifting device for the stirring rake; It consists of a traveling device consisting of caterpillars (infinite tracks) disposed at the front and rear of the lower part of the box, and an elevating device for the traveling device.

[Function] The coastal trash collection device of the present invention moves forward by driving a traveling device with caterpillars attached to the front and back of the lower part of the box on the land part of the beach, and uses a bar with a rake that rotates and moves up and down the trash scattered on the beach. The waste is scooped up by a rake (plow) on a screen or a mesh screen with a rake and stored in a waste storage tank. In addition, while underwater, while adjusting the height appropriately using the lifting device attached to the caterpillar so that the sea level does not reach the water line of the box, it moves on the seabed and moves to a bar screen with a rake (or a mesh screen with a rake). A propeller-driven or pump-driven water current generating device is used to generate a seawater current, and debris from the sea is collected.At the same time, the debris that accumulates on the seabed is scooped up by a rake, and along the way, sea sand and seawater are separated and screened. Garbage such as garbage is stored in the storage tank located at the rear. When the storage tank is full of stored garbage, it returns to land.

The bottom plate of the storage tank is opened and discharged onto a designated conveyor transport means or dump truck.

By selectively using the lifting and lowering operations (single operation) on both flat and sloping ground, it is possible to perform lifting and lowering operations while holding the box l horizontally, regardless of whether it is on flat ground or on a sloping ground.

Next, details of the structure of the rake-equipped bar screen 3 will be explained.

FIG. 4 is a perspective view of the bar screen 3 with rake, and FIG. 5 is a front view. This bar screen 22 has a length such that one end thereof is located at the seawater side opening at the bottom of the box 1, and the other end is located within the garbage storage chamber IC of the box 1.
As shown in the figure, by arranging a plurality of screen pars 24 in parallel, a bar gap 26 of a constant width is formed between each screen par 24. This bar screen 22
serves as a conveyance path for the collected garbage.

A rake means 28 is also built into the bar screen 3 with a rake that incorporates the bar screen 22. This rake means 28 includes sprocket wheels 30, 32 installed at both ends of the bar screen 22 so that the center of rotation is located on the axis. The sprocket wheel 30 on the side of the box 1 is a drive side, and a drive device (not shown) equipped on the box 1 and a gear reduction device or a chain or the like are connected via a transmission means. Sprocket wheels at both ends like this 30.32
As shown in detail in Figure 4, the link chain 3
6 is wound around the link chain 36, and the driving direction is set so that the upper side of the link chain 36 when the box 1 is in the garbage collection state is the upper garbage transport side. A pair of such link chains 36 are arranged along the side edges of the bar screen 22 so as to sandwich the same, and the link chains 36 on both sides of the bar screen 22 are connected by claw holding irons 38 and driven synchronously. The pawl holding rods 38 are attached in parallel at regular intervals along the conveying direction of the link chain 36, and the pawl holding rods 38 are provided with a plurality of rakes (raking pawls) corresponding to the bar gaps 26 of the bar screen 22. ) 40 are provided. That is,
The rake 40 is penetrated and supported by the claw holding ronds 38 that extend over the link chains 36 on both sides, and one side projects outward and the other side faces inward, and the bar screen 22
The bar is configured to slide through the bar gap 26 of the bar. Therefore, the link chain 36 is driven by the rotation of the sprocket wheels 30, 32, and the rake (raking pawl) 40 is also rotated accordingly.

Here, the bar screen 22 is connected to the link chain 36.
It is installed in parallel slightly below the upper conveyance surface of 1. The upper and lower ends are respectively fixed to rotating shafts 31.33 of sprockets 30.32 via bearings 31a and 33a. ti raising nail 4

The rake (I-raking claw) 40 has a shape that is partially or completely curved toward the conveying downstream side so that the dirt scraped up while running on the bar screen 22 does not fall off. There is.

It is more convenient if the above-mentioned bar screen 3 with rake is constructed so that it can be raised and lowered and reciprocated using a power means such as a hydraulic cylinder so that the entire device can be moved up and down according to the depth of the sea.

2. The rake-equipped bar screen 3 has a mesh stretched over a frame body which is continuously connected at every l pitch of the link chains 36 on both the left and right sides, and has a bar screen 3 with a mesh extending outward from the frame body at the lower end thereof, almost perpendicularly to the frame body. It may also be a mesh-type screen with rakes attached to it.

The operation of the garbage collection device of the present invention configured as described above will be explained.

First, in collecting scattered garbage on land areas such as sandy beaches and waves, the traveling device 2 with caterpillars is driven to move forward, and the rake 40 scoops up the garbage by rotating the rake-equipped bar screen 3, and the garbage is sequentially scooped up by the sprocket 30 at the top. After turning over and sliding the grizzly 6a, it is stored in the garbage storage tank 6. During this time, the sand and water scooped up at the same time as the garbage will not fall down and enter the garbage storage 4116, or even if it does, it can be suppressed to a small amount.

In addition, in the sea or shallow sea (for example, at a depth of 1 m to 1.5 m), as shown in Figs.
is driven to drive a bar screen 3 with a rake to collect garbage existing in seawater or on the seabed.

In particular, when collecting dust buried in the seabed, the bottom end of the bar screen 3 with rake is grounded on the seabed, and the hydraulic cylinder of the lifting device 4a of the stirring rake 4 is pushed down to remove some of the sand in the seabed. After being buried in the layer, the agitation rake 4 is driven to rotate to dig up the buried debris, and then similarly collected by a rake-equipped bar screen (or mesh screen) installed on the rear surface by the flow of seawater. be able to.

Note that although both FIG. 1 and FIG. 3 show examples in which the seabed is horizontal, when the seabed is sloping, the elevating devices 2a of the four traveling devices 2 may be raised and lowered independently as appropriate. If the operation is carried out while adjusting the water depth and keeping the box l almost horizontal, the collection work can be carried out safely, easily and smoothly. When the garbage storage tank 6 is full of garbage, the bottom plate 6b is opened at the discharge point on land and the garbage is discharged to a hopper, conveyor, dump truck, etc.

As described above, (1) the coastal trash collection device of the present invention can mechanically and continuously collect trash not only on the beach or on the shore near the waves, but also in the sea or on the seabed, easily by the operator's operation. At the same time, it is possible to efficiently separate and collect only garbage from sand and seawater. Also, in the sea,
Floating debris and debris on the seabed can be collected by gently scooping them up, resulting in relatively little pollution of the sea area.

[Effects of the Invention] As explained above, according to the coastal garbage collection device according to the present invention, the garbage storage has a bar screen with a rake or a mesh screen with a rake and a bottom plate that can be opened, which is housed in a box. Since the garbage collection unit consists of a tank, a water flow generator, a traveling device with a lifting device, and an agitation rake with a lifting device, it is possible to selectively collect only the garbage from sand and moisture, and it is possible to It is possible to freely, continuously, automatically and efficiently collect garbage both on land and underwater. In particular, the provision of a stirring rake makes it easy to collect debris buried on the seabed. Also, since the rake only scoops up dirt, it does not significantly pollute the sea area.
