Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a beach cleaner used for cleaning sandy beaches such as beaches.

(Prior technology) A beach cleaner that picks up and collects empty cans, paper scraps, and other trash scattered on sandy beaches such as beaches has a scooping section located at the front of the machine that scoops up trash along with sand. There is also a system in which the sand scooped up by this scooping section is separated from garbage by a conveyor and sieved out, and the garbage is thrown into a container.

(Problem to be solved by the invention) However, in conventional beach cleaners, garbage was thrown into the container from the terminal end by simply rotating the sieve conveyor, so if the sand was wet, , sand and other deposits remained attached to the sieve conveyor and could not be sieved sufficiently.

In view of such conventional problems, an object of the present invention is to improve the sieving efficiency of the sieve conveyor by reliably removing deposits such as sand on the terminal end side of the sieve conveyor.

(Another Means for Solving the Problem) The present invention provides a means for solving the problem, in which a scooping section 7 scoops up the garbage together with sand, and a sieve conveyor 9 sieves the sand while collecting the garbage into a container 10. In this beach cleaner, the sieve conveyor 9 includes a large number of conveyor plates 24 made of an elastic material in which a large number of holes 27 are formed and are spaced at equal intervals in the rotation direction, and the front end of each conveyor plate 24 on the rotation direction side is attached to the endless body 23 that supports it, and the rear end portion of each day conveying plate 24 opposite to the rotating direction is overlapped with the conveying plate 24'' on the rear side so as to be able to approach and separate from the sieve conveyor 9. Regulating members 28 are provided on both left and right sides of the terminal end to restrict the transport plate 24 from jumping up in the -L direction.

(Function) After scooping up sand and garbage in the scooping section 7, the sieve conveyor 9 transports the garbage to the rear while sieving off the sand, and throws it into the container 10.

On the conveyance side A on the upper surface side of the sieve conveyor 9, garbage ((1
The deposited sand and the like fall downward through the numerous holes 27 of each conveyor plate 24. Furthermore, on the return side B of the sieve conveyor 9, each conveyance plate 24 is in a hanging shape, so the sand sieved on the conveyance side A is
It passes through the gap between the transport plates 24 and falls downward. On the terminal end side of the sieve conveyor 9, each conveyor plate 24 is elastically deformed rearward,
At that time, the centrifugal force causes deposits such as sand to be thrown into the container 10 along with the garbage. In addition, the regulating member 28 allows the transport plate 24 to
Because the jump and 1-gari are regulated, the moment you pass this? The general transporter 24 throws the garbage backwards.

(Example) The invention will now be described in detail with reference to the illustrated embodiments.

Note that the drawings illustrate a self-propelled beach cleaner. Fifth
In the figures and FIG. 6, ] is the aircraft body, which has a pair of left and right crawler type traveling devices 2. A control device 3, a pilot seat 4, an engine 5, a fuel tank 6, etc. are arranged on the left and right sides of the aircraft body 1. Further, in the machine body 1, a scooping section 7, a lifting conveyor 8, a sieving conveyor 9, and a container 10 are arranged in the front and rear direction.

The scooping section 7 is for scooping up dust as well as sand, and is composed of a scraper or the like, and is supported between the front ends of the side plates 11 of the lifting conveyor 8 in a downwardly extending manner. In addition,
This scooping part 7 has a front floor-like shape and is configured to be larger than the horizontal width of the machine body 1. Further, a resin plate or the like is attached to the lower surface of the scooping part 7 to make it easier to slide.

The lifting conveyor 8 separates sand from garbage among the sand and garbage scooped up by the scooping section 7, and lifts the sand while sieving out most of the sand. A wire mesh conveyor belt 15 is wound endlessly between rolls 13 and 1.4 supported between rolls 11 and 11.

This lifting conveyor 8 is provided in a raised shape through a side plate 11, and is supported by a support shaft 1G of a roll 14 at the rear end.
It is supported so as to be movable downward, and also to be movable up and down by an elevating cylinder 17 interposed between the side plate 11 and the body 1.

The sieve conveyor 9 receives the garbage lifted by the lifting conveyor 8 and throws it into the container 1° while further sieving off sand, etc. The sieve conveyor 9 has a pair of left and right side plates 18 fixed on the machine body 1.
A pair of left and right sprockets 1-21 and 22 supported by support shafts 19 and 20 are disposed between both ends of the sprockets 19 and 20, and a pair of left and right belts 23 are wound between these sprockets 2L22. A large number of conveyor plates 24 are attached to the plate. The sprocket 2I is driven by the engine 5 through a transmission mechanism together with the roll]4, and the belt 23 has each sprocket 2I as shown in FIGS. 1 and 2.
, , 22 has an interlocking part 25 on the inner peripheral side. As shown in FIGS. 1 to 3, between the pair of left and right belts 23, a large number of support plates 26 are horizontally suspended at equal intervals in the rotating direction (arrow a) of the sieve conveyor 9. The front end portion of each conveyor plate 24 in the rotating direction is attached to the plate 26 . The rear end portion of each conveyance plate 24 on the opposite side to the rotating direction is superimposed on the front end portion of the conveyance plate 24 on the rear side so as to be able to approach and separate.

The conveyance plate 24 is made of an elastic material such as rubber, and has diamond-shaped or round-shaped holes 27, as shown in FIG. 4, formed in the entire area except for the periphery.

The hole 27 is large enough to prevent the pull top of the can from falling out.

A regulating member 28 is attached to a pair of left and right side plates 18 on the terminal end side of the sieve conveyor 9 to restrict upward jumping of the conveyor plate 24 on the terminal end side. This regulating member 28 guides the waste on the sieve conveyor 9'' to the center, and
2 and the belt 23, the rear side is bent inward and attached.

The container 10 consists of a container, a bucket, etc., and a parallel link mechanism 30 is attached to a pair of left and right columns 29 erected at the rear of the fuselage 1.
The dump cylinder 34 is supported by a dump cylinder 34 and is movable up and down by the expansion and contraction of the lift cylinder 31, and is interposed between the arm 32 of one parallel link mechanism 30 and a fixed bracket 33 on the side of the container 10. Due to expansion and contraction, the rotation axis 35
Dump operation is possible around the area.

Note that the container 10 has approximately the same length as the scooping part 7.

In the above configuration, when performing cleaning work, the front part of the lifting conveyor 8 is lowered, and the scooping part 7 is pushed into the sand to about 15 to 20c+n and travels forward. Then scooping section 7
scoops up sand and trash together, and a lifting conveyor 8 sieves the sand and trash and lifts the sand while sieving it downward.
After the sand is further sieved by a sieve conveyor 9, the garbage is thrown into a container 10 from the terminal end and collected.

In this case, on the conveying side A of the sieve conveyor 9, a large number of conveying plates 24 are stacked one on top of the other, so the garbage is conveyed rearward while riding on these conveying plates 24. Sand and the like adhering to the conveying plate 24 or dust are sieved downward from the holes 27 of the cutting plate 24 by being subjected to vibrations. On the other hand, on the lower return side B of the sieve conveyor 9, each conveyor plate 24 is made of an elastic material, so it hangs downward from the support plate 26, and a large gap is created between adjacent support plates 26, so that Sand and the like fall downward through this gap and do not adhere to the conveyance plate 24 on the return side B. Furthermore, even when the conveying plate 24 hangs down and vibrates, the sand and the like adhering to the conveying plate 24 are removed by the vibrations and fall.

Sieve conveyor 9] To the conveyance side with garbage loaded on the second side〇) Since the conveyance plate 24 is guided along the regulating member 28 on the terminal end side, it will not jump up in two directions due to the centrifugal force when rotating. It rotates to the rear side of the sprocket 22 while maintaining the same state. Then, at the same time as it reaches the rear side of the sprocket 22 and passes through the regulating member 28, the portion above the support plate 26 of the conveyor plate 24 is elastically deformed rearward due to centrifugal force during rotation and its own elastic force. Due to the centrifugal force at this time, not only dirt but also sand and other deposits adhering to the surface of the conveyor plate 24 are thrown into the container 10.

After that, each conveyance plate 24 returns to the starting end side in a hanging state. By providing the regulating member 28, the timing at which the conveyor plate 24 at the end of the sieve conveyor 9 throws away sand etc. due to its elasticity can be regulated, and when the dust is thrown away, it does not fly over the container 10. .

When discharging the garbage in the container 10, the lifting cylinder 3
1 is extended and the container 10 is held rearward and upward, and then the dumpers 1 and 1 34 are extended to dump the container 10 around the rotating shaft 35.

Note that the conveyance plate 24 may be constructed of a synthetic resin plate, a wire mesh, or the like. Further, in the embodiment, the heald 23 is illustrated as an endless body, but a chain or the like may also be used.

When the width of the sieve conveyor 9 is wide, the regulating member 28 may also be provided in the central portion. The sprocket 22 may be replaced with a sprocket.

(Effects of the Invention) According to the present invention, the sieve conveyor 9 includes a large number of conveyor plates 24 made of an elastic material in which a large number of holes 27 are formed, and which are arranged at regular intervals in the rotational direction, and each conveyor plate 24 is rotated. The front end on the side in the moving direction is attached to the endless body 23 that supports it, and the rear end on the opposite side to the rotating direction of each day feeding plate 24 is superimposed on the conveying plate 24 on the rear side so as to be able to approach and separate. , Since regulating members 28 are provided on both left and right sides of the terminal end of the sieve conveyor 9 to restrict upward jumping of the conveyor plate 24, deposits such as sand are reliably removed at the rear end of the sieve conveyor 9. Furthermore, sand and the like falling from the conveyance side do not fall and adhere to the conveyance plate 24 on the return side, and therefore the efficiency of sieving sand and dirt is significantly improved. Further, a regulating member 2 is provided on the terminal end side of the sieve conveyor 9.
8, it is possible to regulate the position at which each transport plate 24 throws away garbage according to the container 10, and the garbage can be thrown away from the container 10.
It never goes beyond that.
