Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a beach cleaner device for efficiently collecting dust on a sandy beach.

[Conventional technology]

Cans, paper, etc. are thrown away on the beaches of beaches, etc., and driftwood from the sea is mixed in, so it is necessary to remove these dusts.

As a beach cleaner device for collecting dust from a sandy beach, for example, one disclosed in Japanese Patent Laid-Open No. 61-277707 is known.

Further, as a beach cleaner device similar to the device shown in this publication, an endless conveyor having a large number of pickup members for scraping and sanding a sand surface is provided on a machine frame of a work vehicle in a rearwardly inclined state to pick up. It is also known to scrape dust on the endless conveyor with a member, but with this beach cleaner device, the operator has to adjust the cleaning depth each time according to the unevenness of the sand surface, which burdens the operator. It was great.

Therefore, a beach cleaner device that does not require adjustment of the cleaning depth even if the sand surface has irregularities is known as shown in FIG. 3, for example.

FIG. 3 shows the main part of the beach cleaner device. As shown in the figure, an endless conveyor 101 having a conveyor net 101A is provided on a conveyor chain 102 in a rearwardly inclined state in a machine frame (not shown) equipped with a traveling device. The upper end of the endless conveyor 101 is moved and circulated backward (in the direction of arrow X) by the conveyor chain 102 driven by the driving force of the driving shaft 103. Also,
The endless conveyor 101 is provided with a large number of pickup members 104 for scraping the sand surface S.

A ski member 105 that is located in front of the endless conveyor 101 and that smoothes the sand surface is fixed to the machine frame.

On the other hand, below the rear part of the endless conveyor 101, a collection box 106 for depositing dust falling from the rear end of the endless conveyor 101 is arranged and fixed to the machine frame.

Then, when the beach cleaner device is run, the ski member 105 follows the irregularities of the sand surface S, and the ski member 105 fills the dust on the surface of the sand surface S with the sand to smooth the sand surface, This is picked up by the pickup member 104 onto the endless conveyor 101. When the endless conveyor 101 moves and circulates, most of the sand overflows from the conveyor net 101A, but dust that has not overflowed falls from the rear end of the endless conveyor 101 and accumulates in the collection box 106.

[Problems to be solved by the device]

However, in the conventional beach cleaner device, if the sand surface S is moist and hard, the pickup member 104 for digging up the sand surface while moving forward escapes from the sand surface,
In the state shown in 04A, the sand surface S could not be sufficiently scraped and unraveled, and therefore dust could not be easily scraped up onto the endless conveyor 101. As a result, the amount of dust collected was small and the collection rate was poor.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a beach cleaner device capable of easily scraping dust even on wet sand onto an endless conveyor to improve recovery efficiency. It is to be.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is an endless conveyor in which a large number of pickup members for scraping a sand surface are attached to a machine frame equipped with a traveling device, and the upper side of the conveyor moves rearward by a driving force of a drive shaft. In addition to the slanting slope, the machine frame is provided with a ski member located in front of the endless conveyor to smooth the sand surface, and dust that falls from the rear end of the endless conveyor is located below the rear end of the endless conveyor. In the beach cleaner device in which a collection box for accumulating is placed on the machine frame, a drive mechanism is provided on the drive shaft, and the drive force is transmitted through this drive mechanism to rotate in the opposite direction to the drive shaft to move the sand surface. The stirrer for scraping sand is arranged between the endless conveyor and the ski member.

[Action]

In the present invention, when the endless conveyor is driven by the drive shaft, the driving force is transmitted to the sand surface stirring device via the power transmission mechanism to rotate.

At this time, the ski member that moves forward fills the dust on the surface of the sand with the sand and smoothes the sand. The sand surface filled with this dust and smoothed is scraped by a sand surface stirring device. The wet and hard sand on the surface of the sand becomes soft and separates into a low density state where the pickup member can easily enter.

As a result, even wet sand is easily dug up by the pick-up member that moves forward, and dust with sand attached is scraped up on the endless conveyor.
