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 art) Garbage such as empty cans, driftwood, and paper scraps scattered on sandy beaches such as beaches. A beach cleaner that picks up and collects sand and garbage is equipped with a scooping section at the front, and the sand scooped up by this scooping section is passed through a sieve while being conveyed to the first conveyor and second conveyor. There is one that allows you to drop the liquid and throw the Go ξ group into a container.

(Problems to be Solved by the Invention) In the conventional peach cleaner, sand was simply separated from garbage and sieved while being transported from the first conveyor to the second conveyor to the container, resulting in the sand being damp. In some cases, the sand adhering to the garbage cannot be sieved out sufficiently, and a large amount of sand ends up in the container together with the garbage.

In view of such conventional problems, an object of the present invention is to reliably separate and sieve sand attached to garbage.

(Means for Solving the Problems) The present invention includes scooping up moss together with sand by the scooping section 5,
In a beach cleaner that sieves sand through a first conveyor 6 and a second conveyor 7 and collects debris into a container 8, the rear end of the first conveyor 6 and the front end of the second conveyor 7 A separation chute 54 for separating sand from garbage falling from the first conveyor 6 to the second conveyor 7 is provided between the first conveyor 6 and the rear end of the first conveyor 6. A comb rod 61 is provided so that the garbage thrown backwards collides with and falls onto the separation chute 54.

(Function) After scooping up sand and grit in the scooping section 5, the first conveyor 6
The sand is sieved through the sieve, and the sludge is conveyed, and then released backward from the rear end. After colliding with the comb rod 61, this thrown garbage falls onto the lower separation chute 54, is guided by the separation chute 54 to the second conveyor 7, and is sequentially collected from the second conveyor 7 into the container 8. Go.

When the sand is released from the first conveyor 6, the sand adhering to the debris is crushed by the impact when it collides with the comb rod 61.
14 and falls onto a separation chute 54 where it is also separated and sieved. Therefore, even when the sand is wet, it is possible to sufficiently separate and sieve out the sand that frequently adheres to dust.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. Note that the drawings illustrate a self-propelled beach cleaner.

The front end side of each arm 72 is attached to a support member 77 installed between the left and right side plates 4 via a pivot 78 so that it can be raised and lowered freely, and a cylinder 79 is installed between the bracket 73 of each arm 72 and the bracket 50 of the vehicle body 2.
is interposed. The four-bar link 68 can swing back and forth by the expansion and contraction of the cylinder 76, and the arm 72 can move up and down by the expansion and contraction of the cylinder 79.

Note that below the separation chute 54 and the second conveyor 7,
A pair of left and right guide plates 80 are provided to guide the sieved sand between the traveling devices 3. Furthermore, a rake 81 is attached to the rear end of the vehicle body 2 via an arm 82 and a pivot 83 for smoothing out sifted sand, unevenness left by the traveling device 3, etc. The cylinder 84 interposed between the second bracket 50 and the arm 82 can be moved up and down by expanding and contracting. A rubber sag 85 is provided on the rear side of the rake 81.

In the above structure, when cleaning a sandy beach, the first conveyor 6 is lowered and the tip of the scooping plate 31 of the scooping section 5 is pushed into the sand by about 15 to 20 cm, and the conveyor moves forward. . Then, the scooping plate 3l scoops up sand and garbage from the beach and sends them backward to the first conveyor 6, so the first conveyor 6 scoops up the sand and garbage with each net body 21. It is sieved and the sand is sieved downward while being lifted up to the rear end. The running speed of the first conveyor 6 is set to be sufficiently fast, and the garbage that has been lifted to the rear end is
When the rope body 21 turns downward at the drive sprocket 16, it is thrown backward and collides strongly with the comb rod 61, and then falls onto the separation chute 54 below. Therefore, even if wet sand is attached to garbage, the sand can be separated from the garbage by the impact of this collision. Also, since the fruit collides with the comb rod 61 and is guided to the separation chute 54, even if the speed of the first conveyor 6 is increased, the fruit ξ
There is no possibility that the particles will be scattered to the rear side of the second conveyor 7.

Since the separation chute 54 is vibrating up and down around the pivot shaft 56 via the connecting rod 57 due to the rotation of the disc 58, the garbage ξ that has fallen onto the separation chute 54 via the comb rod 61 is subjected to the vibration, and the garbage The sand attached to the grains is separated from the chute 5.
4 will be further filtered out. Then, the garbage is sequentially collected from the separation chute 54 via the second conveyor 7 into the container 8.

The garbage collected in the container 8 is loaded onto the loading platform of a truck or the like. In this case, first, the four-bar link 68 is extended rearward by extension of the cylinder 76, and then the arm 72 is raised by extension of the cylinder 79. When the container 8 reaches an appropriate height, the cylinder 71 is extended to dump the container 8 around the pivot 69, and the garbage is dropped from the opening and loaded onto the loading platform.

In the embodiment, the separation chute 54 is of a vibrating type, but it may be fixed to the side Fi4 or the like.

(Effects of the Invention) According to the present invention, between the rear end of the first conveyor 6 and the front end of the second conveyor 7, sand is removed from debris falling from the first conveyor 6 to the second conveyor 7. A separation chute 54 is provided to separate the particles from the first conveyor 6, so that the gourds thrown backward from the first conveyor 6 collide with the outer vicinity of the rear end of the first conveyor 6 and fall onto the separation chute 54. Since the comb rod 61 is provided in the container, even if the sand is wet, the sand adhering to the garbage can be sufficiently sieved off, so that a large amount of sand does not enter the container together with the garbage as in the conventional case. There isn't.
