Description: TECHNICAL FIELD The present invention relates to a self-propelled beach cleaner for cleaning a sandy beach or the like.

(Prior art) A beach cleaner that picks up and collects garbage such as empty cans, driftwood, paper waste and the like scattered on a sandy beach such as a beach, scoops garbage with sand in front of a self-propelled airframe. A scooping unit to be raised is arranged, and a container for collection is arranged at the rear. There are things that I try to do.

It is necessary to transfer the collected garbage to a truck or the like.However, the conventional container is detachably attached to the body, and when a predetermined amount of garbage accumulates, the container is removed from the body by manual work and the garbage is removed. In general, a type in which trash is transferred or a type in which dumping operation is performed around a pivot at an attachment position to discharge refuse in a container is performed.

(Problems to be Solved by the Invention) In the case of the former former type, the work of transferring the trash in the container is very troublesome, and in the case of the latter type, the truck is directly dumped by the dumping operation of the container. In order to transfer the garbage to the container, the container must be provided at a high position, and there is a problem in safety of operation on a slope or the like. Further, in the conventional container, the collected garbage is simply put therein, and the garbage is collectively placed in one place, and the garbage is later scooped up using the container and loaded into a truck or the like. For example, it was not possible to perform a loading operation like a front loader.

In addition, International Publication No. 90-10754 pamphlet (1990)
In this publication, a self-propelled beach cleaning operation is provided in which a collection receiver is provided at the rear of a refuse pickup comprising a V-shaped pickup header and an elevator, and when the refuse is collected in this container, it is transferred to a dump carrier. A car has been proposed.

However, this cleaning work vehicle cannot collect waste such as empty cans buried in sand, and the work vehicle itself is large because it has a dump truck.

Therefore, an object of the present invention is to provide a beach cleaner capable of safely and efficiently performing a sieving and collecting operation of garbage deposited or buried on a sandy beach and performing a loading operation like a front loader on a truck or the like. .

(Means for Solving the Problems) The present invention relates to conveyors 6, 7 for transporting sand that has been scooped up together with dust and the like by the scooping unit 5 to the traveling machine body 1 while sieving the sand, and conveyors 6, 7, In order to achieve the above-mentioned object, the following technical measures are taken in a beach cleaner provided with a bucket 8 for storing garbage from 7.

That is, in the present invention, a lift arm 73 that can be raised and lowered is provided between the left and right side plates 4 of the traveling machine body 1 with a pivot 79 at the front end side as a fulcrum. Receiving position C for receiving garbage from the conveyors 6 and 7 in a state of being inserted between the left and right side plates 4 and inserted.
Bucket 8 between the front and rear sides D and between the left and right side plates 4 and the rear position D.
And a lift cylinder 80 for raising and lowering the lift arm 73 so that the bucket 8 moves up and down between a rear position D and an upper raising and lowering position B. Is what you do.

(Operation) During the work of collecting garbage scattered or buried in the sandy beach, the lift arm 73 is lowered to the bucket 8 in the receiving position C in which the bucket 8 is inserted between the left and right side plates 4.
To run forward.

Then, the garbage is scooped up by the scooping unit 5 at the front, and the garbage is conveyed rearward while the sand is sieved by the conveyors 6 and 7 and the garbage is put into the bucket 8.

Therefore, at the time of this collection work, the position of the center of gravity of the whole becomes low, and the work can be performed safely even on an inclined ground, and the bucket 8 is inserted between the left and right side plates 4.
The left and right side plates 4 function as a guard, and surely put trash into the bucket 8.

When the refuse is collected in the bucket 8, the trash is loaded onto a truck or the like. First, the bucket 8 between the left and right side plates 4 is moved to the rear position D by extending the cylinder 77, and then the lift cylinder is moved. The lift arm 73 is raised by 80 and the bucket 8 is raised to the raised position B, and then the bucket 8 is dumped.

The fork working tools 67 may be arranged in a large number in the left-right direction, or may be provided in two to six at intervals in the left-right direction.

In the bucket 8, each side plate 59 is pivotally connected to a four-bar link 69 on both left and right sides by a pivot 70, and a fixed link at the tip of the four-bar link 69
A dump operation can be performed around the pivot 70 by expansion and contraction of a cylinder 72 provided between the side plate 59 and the side plate 59. Each four-bar link 69 is pivotally attached to the rear end of a pair of left and right lift arms 73 disposed between the side plate 4 and the conveyor frame 44, and a bracket 74 fixed to this arm 73 and a four-bar link 69 A cylinder 77 is interposed between the link 75 and a fixed bracket 76.
Each of the lift arms 73 is pivotally connected to a support member 78 provided between the left and right side plates 4 by a pivot 79 so that the front end thereof can be moved up and down. A lift 74 is provided between the bracket 74 of each lift arm 73 and the bracket of the vehicle body 2. A cylinder 80 is interposed. The four-bar link 69 can swing back and forth by the expansion and contraction of the cylinder 77, and the lift arm 73 can be moved up and down by the expansion and contraction of the cylinder 80.

In the above configuration, when cleaning the sandy beach,
The first conveyor 6 is lowered to travel forward with about 15 to 20 cm protruding into the sand at the tip of the scooping plate 31 of the scooping unit 5.
Then, the scooping plate 31 scoops up the sand on the sandy beach and the trash together, and sends them to the first conveyor 6 rearward. Raise the sand to the rear end while sifting the sand downward. The forwarding speed of the first conveyor 6 is set to be sufficiently high, and the refuse that has been lifted to the rear end is released backward when the carrier 21 turns downward at the driving sprocket 16 portion. After strongly colliding with the comb 55, it falls onto the separation chute 52 below. Therefore, even when wet sand adheres to the dust, the sand can be separated from the dust by the impact at the time of the collision. Garbage is comb rod 55
, And is guided to the separation chute 52, so that even if the speed of the first conveyor 6 is increased, dusts may be generated on the second conveyor 7.
There is no scattering to the rear side.

Since the separation chute 52 is vibrating up and down, the comb 55
The dust that has fallen on the separation chute 52 through the above is subjected to the vibration, and the sand adhering to the dust is further combed down by the separation chute 52. And the trash is separated chute 52
, Through the second conveyor 7 and sequentially into the bucket 8.

At the time of this collection, the bucket 8 is positioned close to the second conveyor 7 with the opening 62 facing upward, and is positioned at the receiving position C which is inserted between the left and right side plates 4. The dust is thrown into the bucket 8 from the opening 62 through the opening 62. At this time, the left and right side plates 4 act as guards, and the throwing into the bucket 8 is ensured.

When the amount of dust in the bucket 8 is reduced, the four-bar link 69 is first extended rearward by the extension of the cylinder 77, and the opening is opened.
After the bucket 8 is separated from the fuselage 1 to the rear position D with the 62 facing upward, the arm 73 is raised around the pivot 79 by the extension of the cylinder 80, and when the bucket 8 is raised to the raised position B, the bucket 8 Since it is separated from the left and right side plates 4, there is no interference between the bucket 8 and the left and right side plates 4. Then, when the cylinder 72 is extended next, the bucket 8 rotates around the pivot 70 at the ascending position B and dumps, so that the trash in the bucket 8 can be loaded from the opening 62 onto a truck bed or the like. .

At the time of the above cleaning work, the carrying work tool 67 is removed from the bucket 8.

As shown in FIG. 1, since the huge driftwood E cannot be stored in the bucket 8, the work implement 67 is mounted on the bucket 8 as shown in FIGS.

When the lift arm 73 is moved up and down by the expansion and contraction of the lift cylinder 80 to move the machine body 1 backward, the driftwood E is scooped by the work implement 67, so that the driftwood E and the like can be transported in the state of the work position D. .

(Effects of the Invention) According to the present invention, a lift arm 73 that can move up and down with the pivot 79 at the front end side as a fulcrum is provided on the body 1, and the bucket 8 is pivotally attached to the rear end of the arm 73 so as to be able to dump. Since the lift cylinder 80 for raising and lowering the lift arm 73 is provided, trash in the bucket 8 can be mechanically and efficiently loaded onto a truck or the like, and the center of gravity of the whole can be lowered to work safely on a slope or the like. In addition, the operation of scooping the sediment on the ground into the bucket 8 and loading the same can also be performed.

Further, since the bucket 8 is inserted between the left and right side plates 4 at the receiving position C, dusts to be thrown in from the conveyor 7 are guarded by the left and right side plates 4 and are reliably thrown in. Since the ascending and descending operation is performed after the rear position D is set rearward, mutual interference between the bucket 8 and the left and right side plates 4 is prevented.
