Description

[Detailed description of the invention] This invention relates to a beach cleaning device that utilizes centrifugal force.

Conventional beach cleaning equipment that uses centrifugal force discharges the sand from which dirt has been removed directly to the outside from the wire mesh section of the rotating body and scatters it around the entire outer circumference, so as the cleaning equipment moves, the same sand is not duplicated. This method had the disadvantage that not only was the trash disposed of, but also the trash exposed on the sand was buried. Furthermore, regarding the ability to collect dirt, because the rotating body was standing upright relative to the raking plate, the sand did not flow smoothly into the rotating body, and the raking blades, which had a large surface area and stood upright, created their own resistance to raking. However, since there was no mechanism for transporting the separated waste, there was also the drawback that the waste could not be completely fed into the waste storage box. Furthermore, the ■-shaped scraping board has the problem that the cleaning depth tends to be uneven due to the influence of unevenness on the ground.

The object of the present invention is to solve the above problems and provide a beach cleaning device that has high cleaning efficiency and can provide a uniform cleaning effect.

The enclosure 27 surrounds the outer periphery of the side wall of the rotating body 11 with a slight gap between it and the sand feeding blades 14, and includes an inclined plate 27a located on the lower side and extending obliquely upward, and an inclined plate 27a extending upward from the inclined plate 27a. It is constituted by an extending vertical plate 27b. Sand discharge ports are opened at appropriate intervals at the rear and sides of this enclosure body 27, but in this example, since the hollow rotating body 11 rotates to the left, the sand discharge ports 28 are opened on the left side of the inclined plate 27a. Opened another sand discharge port 28a,
28b, 28c, 28d, and Z8e are opened at the rear to limit the sand scattering area (see Figure 5).

The housing portion 31 surrounds the upper edge of the hollow rotating body 11 with a slight gap between it and the dust feed blade 15, and the inner peripheral portion of the bottom plate 31a is fixed to the vertical plate L/-127b. A pair of guide plates 31b are fixed perpendicularly to the outer edge of the bottom plate 31a (see FIG. 4), and the upper edge of the guide plate 31b is in close contact with the bottom of the flat plate 20a.

The scraping body 41 is attached to the lower edge of the inclined plate 27a, and is composed of a curved portion 41b surrounding the rear half of the lower edge of the hollow rotating body 11, and a pair of scraping plates 41a that expand forward from the curved portion 41b. . The axis of rotation 17 of the rotating body 11 is 50° with respect to the horizontal line formed by the lower edge of the scraping body 41.
The lower edge opening of the hollow rotating body 11, which is tilted backward at an inclination angle in the range of 70° to 70° and has an upward slope, serves as an inlet for sand into the hollow rotating body Il.

A pair of trash storage boxes 32 are suspended from the crosspiece frame 20 in contact with both sides of the storage section 3I. Each wall surface is made of wire mesh, the side surfaces are rectangular, an intake port 32a for taking in the garbage from the storage section 31 is provided on the inner side, and a door 32b for taking out the garbage is provided on the front side.

Next, FIG. 6 shows a second embodiment. The beach cleaning device 1a uses a screw as a scraping mechanism. The screw type scraping structure 42 includes a screw 43, an outer frame 44 surrounding the screw 43, and a hydraulic motor 46 that drives the screw 43.

The outer frame body 44 pivotally supports the rotating shaft of the screw 430 on both sides thereof, and supports the guide frame body 4 on both sides of the screw 43 [surface, upper surface, and rear surface].
It surrounds the outside of 5.

The guide frame body 45 includes a curved portion 458 surrounding the rear half of the lower edge of the hollow rotating body 11, a pair of side plates 45b provided forward from the curved portion 458, and a cover plate 45C whose ends are the upper edges of the side plates 45b. configured. The front end of the guide frame 45 is fixed to the rear surface of the outer frame 44, and the upper edge of the curved portion 458 is fixed to the inclined plate 27a.

In the beach cleaning device 1a, a hydraulic motor 47 is mounted as a drive mechanism for the hollow rotating body 11, and the driving hydraulic pressure can be easily supplied from the tractor 2 together with the hydraulic motor 46 for the screw. The other configurations are the same as the beach cleaning device 1 of the first embodiment.

The operation of the first embodiment will be explained using FIG. 1.

First, by driving the prime mover 24 to rotate the rotating body 11 and then operating the lift arm device 3 of the tractor 2, the raking body 41 of the beach cleaning device 1 is placed horizontally on the sand, and from there the target cleaning depth is set. Let it sink to the top. In this state, move forward in the direction of arrow F.

Now, as the beach cleaning device 1 moves forward in the F direction in the action explanatory diagram of FIG. 4, the scraping plate 418 scrapes up sand mixed with dirt and guides it to the lower edge opening of the hollow rotating body 11. Since this lower edge is upward-sloping, the sand penetrates to the inside of the rotating body II, where it is given a centrifugal force by the scraping blade +3VC, and an upward component of this centrifugal force is applied along the inner circumferential surface. As a result, as shown by arrow G, the rotating body II begins to rotate upward along the inner circumferential surface. While the sand is being released from the metal net 12 during the upward movement, the objects remaining inside the rotating body 11 (hereinafter referred to as dust) are supplied with centrifugal force from the metal net 12, which acts as a friction plate, and the objects that remain inside the rotating body 11 are kept at the upper edge of the rotating body 11. reach the department. The garbage that has reached the upper edge is further accelerated by the garbage sending blade 15, guided by the guide plate 31b of the storage section 310, passes over the bottom plate 31a as indicated by arrow G', and enters the garbage storage box 32 from the intake port 32a. Completely stored.

On the other hand, the majority of the discharged sand is received in the tank enclosure 27, and is guided to the sand discharge port 28 by the sand feed blade 14 as indicated by the broken arrow S, and is discharged. The remaining sand is directly discharged from multiple sand outlets. In this example, since the rotating body 11 rotates to the left, the sand discharge port 2 is located on the left side as shown in FIG.
8, and sand discharge ports 28a and 28 provided on the rear side.
Together with b, 28d, and 28e, it is possible to evenly spread sand onto the passage surface through which the beach cleaning machine 1 passes, as indicated by the broken line arrow S'.

In the case of the beach cleaning machine 1a of the second embodiment, the screw-type raking structure 42 scrapes up sand and sends it into the hollow rotating body 11, and the following operations are the same as in the previous example.

The feature of this invention is that it maximizes the effects of centrifugal force, which is used for raking objects, storing goba, and scattering sand. First of all, the scraping blades are installed only near the lower edge, and are curved upwards to minimize the resistance of the scraping blades themselves against swirling motion, and the supporting arms also have low resistance. By creating a curved cross-section, a great scraping effect was obtained.

Next, by forcibly sending the garbage into the garbage storage box using the garbage sending blade, it is possible to prevent garbage from accumulating in the storage area and interfering with the operation of the entire device.

Thirdly, an enclosure with a sand outlet and sand feeding blades are installed.
By tilting the rotating shaft backward, we succeeded in spreading the sand from which the lint was removed only on the surface to be cleaned after passing through the cleaning machine.

Regarding sand raking, by setting the angle between the hollow rotating body and the raking plate to a backward angle of 50'-'70°, it became possible to send sand smoothly into the inside of the hollow rotating body. Furthermore, when a screw-type raking structure is used, the raking part and the raking part are close together, so it is less affected by surface irregularities than the raking plate, and the sand is reliably raked to the center of the device at a constant depth. can be done.
