Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beach cleaner which can be attached to a tractor or the like as an attachment.

[0002]

2. Description of the Related Art There are known various types of beach cleaners (shore cleaning work vehicles) for moving up and collecting garbage (garbage) scattered on a sandy beach. 2. Description of the Related Art Conventionally, as a beach cleaner, a towing traveling type that performs work by towing traveling with a tractor (for example, Japanese Patent Laid-Open No. 7-22 / 1995).
No. 4,413, JP-A-6-12519) or a vehicle that is itself a self-propelled dedicated vehicle (for example, JP-A-11-229338) has been proposed.

[0003]

The conventionally proposed beach cleaners are large in both the towing travel type and the dedicated vehicle type, and are disadvantageous in that they are expensive, heavy, and cumbersome to handle. are doing. In addition, all of the systems have running wheels behind the position where the dust is scooped up from the sandy beach, so that there is a drawback that a rut is formed on the beach after the cleaning operation. In addition, a collection / transportation section that collects trash from the sandy beach and separates it from the sand is located inside the frame, and a bucket that collects trash at the rear interferes with the screen, scraping claw, and fishing line. It has been difficult to remove it. Further, in the case of the towing type, since the bucket is always at the same height, the collected trash can always be discharged only at the same height position.

The present invention has been made in view of the above circumstances, and is a fir that can be easily attached to an existing vehicle such as a tractor as an attachment, is easy to handle, has a simple structure, is inexpensive, and has been worked. It is an object of the present invention to provide a beach cleaner that can clean a sandy beach cleanly and efficiently without making a running wheel rut on the seaside.

[0005]

A beach cleaner according to the present invention for solving the above-mentioned problems is linked to a traveling body such as a tractor so as to be able to move up and down freely, and a number of tines are arranged at appropriate intervals on an endless belt. Forming a dust transport path that tilts upward in the rearward direction and arranges the dust transport path in an endless drive manner, and a dust bucket is disposed so as to be tiltable so as to face below the upper end of the dust transport path of the tine belt. It is characterized by the following. The garbage bucket has a bottom cover that can be opened and closed, the bottom cover is always locked in a closed state, and a bottom cover locking / opening mechanism that can automatically open dust collected in the bucket when discharging the dust. have.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a state where the beach cleaner 1 according to the present embodiment is mounted on a tractor T indicated by a virtual line. The beach cleaner 1 is the main frame 1
The tractor T is provided with a tine belt 11 and a garbage bucket 12, and is attached to the tractor T so as to be detachable and vertically movable by a lifting link mechanism including three lifting and lowering adjustment links 2 provided on the tractor. Therefore, the tine of the tine belt described later moves while scraping the sandy beach during the work, but can move without contact with the ground surface by lifting the entire beach cleaner in the non-working state. The drive mechanism of the tine belt is connected to the PTO shaft 4 of the tractor,
Further, a hydraulic circuit of a cylinder device 26 for driving the trash bucket is connected to the tractor, so that all can be controlled from a driver seat of the tractor.

The tine belt 11 has chains 1 on both sides.
The endless belt 16 is supported by the endless belt 5 and a plurality of tines 17 are fixed to the endless belt 16 in a staggered manner at a constant pitch as shown in FIG. The tine belt 1
As shown in FIG. 1, the chain 15 on both side ends of the drive shaft 13 is a drive shaft 13 bearing on the main body frame 10 and an upright frame 23 erected obliquely rearward from the main body frame 10.
The shaft is endlessly wrapped around a chain sprocket provided on a take-up shaft 19 and a return shaft 20 which are mounted on the shaft, and is arranged so as to circulate a substantially triangular path in the vertical direction.

[0008] The tine 17 is made of wire, as shown in FIG.
(B) As clearly shown in (c), the base is fixed to the endless belt 16 with a stainless steel plate 18 interposed therebetween, and wound in a helical spring shape a plurality of times, and then vertically raised from the belt surface. The triangular path is formed to have a slightly inclined shape with its leading end directed in the traveling direction, and the leading end bites into a sandy beach in the scraping path at the lower end of the triangular path so as to scrape up dust. As described above, the tine 17 has a helical spring shape at its base, so that the tine 17 has flexibility as a whole against dust by a spring action, and effectively scrapes up dust regardless of the shape and size of the dust. And is strong without damage. Further, in the present embodiment, since the plate, bolt, nut and the like for fixing the tines are formed of stainless steel, they do not rust and have durability.

In FIG. 1, reference numeral 21 denotes an arc-shaped guard provided on an outer peripheral portion of a turning portion from a scraping path to a conveying path in which a tine belt scrapes dust from a sandy beach and conveys the dust upward. Is pivotally attached to the drive shaft 13, and the opposite end 36 is pivotally attached to an adjustment bolt 24 provided on the main body frame 10. By adjusting the adjustment bolt 24 up and down, the lower end surface of the arc-shaped guard is formed. Height position can be adjusted arbitrarily. The arc-shaped guard 21 is provided for preventing the tines from scraping heavy objects such as large stones and guiding the dust scraped by the tines to the inclined orbit.
Plays two roles.

The trash bucket 12 is formed of stainless steel and has a width in the width direction larger than the width of the tine belt, so that trash conveyed by the tine belt naturally falls into the bucket at the upper end of the tine belt. The upper end of the tine belt is open, and is disposed below the upper end of the tine belt. The garbage bucket has a frame on its side, as shown in FIG.
And, as clearly shown in FIG.
The tip is rotatably attached to a shaft 25 provided on the main body frame in an overhang shape above the tip of the tine belt. Reference numeral 26 denotes a cylinder device disposed between the main body frame and the dust bucket, and by driving the cylinder, the angle of the dust bucket can be arbitrarily changed as shown by a virtual line in FIG. Thereby, the refuse collected in the bucket can be discharged at an arbitrary height.

As shown in FIG. 3, the bottom cover 28 of the trash bucket 12 is rotatable by a hinge 29, and is normally locked by a locking hook 30 to maintain a closed state. I have. The locking hook 30 is pivotally connected at its upper end to a side wall frame 31 of the bucket via a bracket, and a spring 32 is connected to the side wall frame 3 at an intermediate portion.
1 and is urged to lock the bottom wall. In addition, a chain 33 is provided between the locking hook 30 and the main body frame so as to be able to apply tension in a direction in which the bottom cover is unlocked so that the length can be adjusted. Therefore, for example, if the chain is tensioned in the state of FIG. 3 and the garbage bucket is rotated by operating the cylinder 26 from that state, the hook is pulled by the chain 33 and moves clockwise in FIG. It pivots and disengages from the bottom lid, opening the bottom lid.

Reference numeral 34 in the figure denotes an auxiliary wheel, which is lowered to a ground position indicated by a virtual line when the beach cleaner is stored.
It is for supporting the beach cleaner, and floats from the ground contact surface during the operation as shown by the solid line.

The beach cleaner of the present invention is constructed as described above, and can be easily mounted on a normal tractor by a lifting link mechanism. By adjusting the lifting position (inclination angle) of the entire beach cleaner with the link mechanism, The amount of penetration of the tine 17 into the sandy beach is adjusted. The adjustment bolt 24
Thereby, the height position of the arc-shaped guard 21 is adjusted. Further, the length of the chain 33 is adjusted to adjust the open position of the bottom cover of the garbage bucket. For example, if the length of the chain is adjusted so that tension is applied when the garbage bucket is rotated to the position shown by the imaginary line in FIG. 1, the bottom cover of the garbage bucket will open at a high position, and The dust can be discharged directly to the loading platform or the like, and if the chain is set to be very short, the bottom cover can be opened with a slight rotation from the state shown in FIG. Perform the above adjustments before starting the work.

As shown in FIG. 1, when the tractor travels, the tine is rotated by the tractor via the PTO shaft to rotate the tine belt 11 clockwise in FIG. Empty cans where the tip of the tine scratches the sand and scatters on the sand,
Scoop miscellaneous garbage such as butts. At this time, since the tines are formed by wire as shown in FIG. 4, the sand is hardly picked up, and only dust is effectively picked up. The picked-up dust is supported by the endless belt 16 and the tines 17, and ascends the dust transport path which is an inclined path as the tine belt rotates. Garbage is collected on an endless belt and tines 17 arranged in a zigzag on the belt.
As a result, even relatively small dust such as butts can be reliably transported without falling, and sand mixed with the dust slides down the belt surface during the climb. Therefore, a sieve for removing sand as in the conventional apparatus is not required.

When the tine belt 11 reaches the top of the dust transport path and the tine belt is inverted, the dust locked on the tine 17 automatically falls into the dust bucket 12 and is stored. Thereafter, the tine belt descends substantially vertically to reach a horizontal path below, and a process of scooping up garbage from sandy ground. By continuously repeating the process, trash falling on the sandy beach can be completely collected.

The beach cleaner of the present invention has no running wheels and is mounted on and supported by a tractor to perform cleaning. Therefore, a rut formed on a sandy beach by wheels of a tractor or a caterpillar (registered trademark) is located behind the beach cleaner. No rut is formed on the sandy beach because it is scratched by the tine of a beach cleaner that cleans, and the sandy beach after cleaning becomes beautiful as if it was swept with a broom.

In order to remove dust from the dust bucket after the work is completed, the cylinder device 26 is driven to rotate the dust bucket 12 about the shaft 25, and when the chain 33 is rotated to the tensioned position, the locking hook is engaged. 30 is pulled to release the locking of the bottom cover 28 by the locking hook 30, and the bottom cover 28
Automatically rotates from the hinge 29, and the refuse in the refuse bucket falls naturally by its own weight and is discharged. Therefore, according to the present invention, by adjusting the length of the chain in advance, the height of the discharge position of the garbage bucket can be arbitrarily adjusted according to the discharge location. Can be discharged automatically.

Further, according to the beach cleaner of the present embodiment, the cylinder device 26 is operated to displace the trash bucket 12 to a high position as shown by a virtual line in FIG. Since there is no obstruction at the part facing the return path part and it is completely open, it can easily face the transfer surface of the tine belt,
When the fishing line or the like is entangled with the tine, it can be easily removed. Although the preferred embodiment of the beach cleaner of the present invention has been described above, the present invention is not limited to the above embodiment, and various design changes can be made within the scope of the technical idea.

[0019]

As described above, according to the beach cleaner of the present invention, it can be easily attached as an attachment to an existing vehicle such as a tractor, is lightweight and easy to handle, and has a simple and inexpensive structure. In addition, the sandy beach can be cleaned cleanly and efficiently without the running wheel rut on the worked seaside. In addition, since the height position of the garbage bucket can be freely adjusted, the collected garbage can be directly discharged to a truck bed or the like. Further, since the trash bucket can be arbitrarily moved from a position behind the tine belt, replacement and cleaning of the tine belt are easy. According to the configuration of claim 2, the bottom cover of the trash bucket can be automatically opened with a simpler configuration, and the trash can be automatically discharged to an arbitrary position.
