Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a towed beach cleaning device that cleans the coast by removing foreign matter such as empty cans mixed in sand.

In addition to driftwood and seaweed that wash up from the coast, the sand on beaches and other tourist spots are filled with empty cans and bottles.

Containing various types of foreign matter, such as paper scraps, not only spoils the appearance but also is extremely dangerous, so it is necessary to constantly clean the foreign matter and remove it efficiently. A towed cleaning device that is connected to a towing vehicle for cleaning has been proposed.

First, the method proposed by Japanese Patent Publication No. 54-13119 uses a truncated cone-shaped rotary sieve that is rotated and pulled by a tractor, and this rotary sieve is used to screen out foreign matter. When foreign matter is removed, the mesh of the sieve cannot be avoided and removal work is extremely difficult, and when coarse matter is collected into the rotating sieve, the sieve is damaged due to its transfer. There are nine drawbacks, and one more.
Since the foreign matter had to be transferred in the direction of the rotating shaft within the rotary sieve, efficient cleaning could not be expected.

Therefore, in order to eliminate these drawbacks, a patent application was filed in 1980-1988.
From 089 K, a nine-screen conveyor type cleaning device using a plow board as a sand scraping device was proposed. This device scrapes up the sand with a plate installed at the front end as the machine advances, guides it onto the running endless screen conveyor, and sieves the sand through the K and K screens that vibrate the screen during transfer. 9 foreign objects are collected into collection packets.

However, in this type of device, the plow board is used as a sand raking device. Sand and foreign matter on the plow board, which is inclined at the ninth incline, may not move smoothly onto the screen conveyor. If the balance between the material to be sorted on the plow plate and the material to be sorted on the screen conveyor is lost, and sand mixed with foreign matter is discharged from around the i-plate to the outside of the machine, cleaning will have to be repeated again. There are 6 or 9 defects, and this is especially true when the foreign object is something that easily rolls around, such as an empty can, or something that is easily caught on the plow plate, such as a string-like object. There were times when I was not guided and had to stop work and remove it. In addition, the material to be sorted on the plow board is moved by the force given by the pulling speed of the towing vehicle, but if the water content of the sand is low, the force that moves the sand away will not be transmitted. Items are not transferred and remain on the plow board, making it impossible to expect highly efficient work.

The present invention has been developed in view of the above points, and is a round plow plate that excavates sand as the machine runs and moves the sieved material to a screen conveyor. To provide a beach cleaning device that improves cleaning efficiency by providing a raking device consisting of a plurality of raking bodies arranged in parallel in the axial direction, thereby facilitating the transfer of sorted materials and handing over to a screen conveyor. It is something.

In addition, what is located at the front end of the chassis 2 and designated by the reference numeral 48 is a buffer plate that protects the guide 33, the raking device [38, etc.] from contact with a towing vehicle when the chassis turns.

The operation of the coast cleaning device configured as above will be explained. Tractor # the device with shackle 1! When the machine is connected to a Chapter O guide and driven on a sandy beach on the coast, as the machine moves forward, the sand containing foreign matter, which is guided by the guide plate 33 so as not to go out of the width of the machine, is excavated by the plow plate 34 and removed. The sand is scooped up to the surface and moved by the following sand on one plate 34 as the machine advances. At this time, a raking device 38 is rotating above the plow plate 34, and the sand moving on the plow plate 34 is scraped up by the plate 42 of this raking device 38.
Furthermore, the tangles are loosened by the action of the tip curved portion, making it easier to lift the seeds, so that the transfer is promoted and the seeds are transferred diagonally upward without being retained on the plow plate 34. The transferred sand is continuously supplied and conveyed onto the wire mesh 25 of the running screen conveyor 19, and at this time, vibration is applied to the wire mesh 25 by the rotation of the sprockets) 27 and 28, For operation, only sand is sorted out from the weekly objects consisting of sand and foreign matter, and is dropped onto the sandy beach through the meshes of the wire mesh 25 and the lower wire mesh 2s, where it is transported 7C.

The remaining 9 empty cans, 1 empty bottle, and 1 sheet of foreign matter after the sorting process continue to be conveyed, and at the end of the conveyance, they are transferred to the screen conveyor 1.
It is released from s and stored in the eastbound packet 43 on the road. After cleaning the coastline in this way, we move to a predetermined collection site and operate the hydraulic cylinder 4T to open and close the cylinder 45. Foreign matter such as empty bottles are discharged and collected. When the hydraulic cylinder 15 is actuated, the side plate 13 rotates and the plow plate 42 at the top of the cylinder rotates.
The raking device & 38 etc. move up and down in unison, making it possible to respond to coastal conditions due to changes in sand moisture, etc., and when driving on the road, etc., by raising it at the height of tt, it is possible to prevent obstacles. Collisions with objects can be avoided.

As is clear from the above description, according to the present invention, in a beach cleaning device, a rotating shaft and a rotating shaft protruding radially from the plow plate located at the front end of the machine base and above the plow plate for excavating sand are arranged in parallel in the axial direction. If a raking device consisting of a plurality of raking bodies is provided, the sand that is scooped up by the plow plate and about to be moved toward the sorting screen conveyor will be scraped by the raking device as much as it rotates. Since the sand can be lifted up, there is no accumulation on the plow board, and even if there is bulky trash in the plow that can easily roll, it is dangerous to return it to the beach, so all of it is taken over by the screen conveyor, facilitating the transfer. Great cleaning efficiency! ! can be improved.
