Abstract

PURPOSE:To efficiently attract and recover shot by rotatably connecting a drum to front wheels with a gear, setting a permanent magnet in the drum and keeping a scraper in contact with the surface of the drum. CONSTITUTION:When the body of a cleaner is pushed forward, front wheels 2 rotate and move forward and a drum 9 connected to the wheels 2 with a gear 11 rotates in a direction reverse to the travelling direction of the body of the cleaner. Shot is attracted to the surface of the rotating drum 9 by the action of a permanent magnet 8 set in the drum 9. The attracted shot is scraped from the surface of the drum 9 by a scraper 3 kept in contact with the surface of the drum 9 and the scraped shot is recovered in a receiving box 4.

However, according to the scraping method, other dust and the like were mixed into the recovered shot, and it took time and effort to separate it. In addition, according to the method of attracting with magnets, the individual yachts have a small surface area and are heavy, so if you want to attract them to the magnet and scream, the magnetic force must be strong. There wasn't. However, when the magnetic force is made stronger, although the adsorption is improved, it takes time to scrape off and collect the shot adsorbed to the magnet, resulting in a significant lack of work efficiency.

In the spot collecting and cleaning machine according to the present invention, when the cleaning machine body is pushed forward, the front wheels rotate and move forward, and a drum connected to the front wheels by a gear or the like rotates in a direction opposite to the running direction of the machine body. Furthermore, when flanges are provided at both ends of the drum instead of the front wheels and gears, the drum rotates together with the flanges in the same direction as the traveling direction of the machine body. Since a permanent magnet is provided inside the drum, the shot is attracted to the surface of the rotating drum, and then the shot is scraped off by a scraper provided in contact with the outer peripheral surface of the drum. Furthermore, the 7M feet scraped off are collected in a receiving box.

The drum magnet 1 consists of a drum 9 and a permanent magnet 8 provided inside the drum 9. The drum 9 is rotatably attached to the frame 6, and gears 1l that mesh with front wheel drive gears 10 are provided at both ends of its outer periphery. This drum 9 is made of a cylindrical body made of austenitic stainless steel, which is a non-magnetic material, and attracts shots to its surface by the magnetic force of the permanent magnet 8 inside.

Then, the shots adsorbed to the surface of the drum 9 will be
Up to the top of the drum 9, the surface of the drum 9 is attracted by strong magnetic force, but in the area where it is scraped off by the scraper 3, there is almost no magnetic force acting on the surface of the drum 9, making it easy to remove shots on the surface of the drum 9. It can be scraped off.

Further, a gal 11 provided on the drum 9 meshes with a drive gear 10 provided on the front wheel 2. Therefore, by moving the main body of the cleaning machine A forward, the drive gear 10 rotates in the direction of arrow a in FIG. 2, and this drive causes the drum 9 to rotate in the direction of arrow b in FIG. therefore,
By simply moving the cleaning machine 8 body forward, the operator can automatically pick up and collect the shots without any special intervention. Note that a latch mechanism (not shown) may be provided on this gear 1l to prevent the drum 9 from rotating in reverse.

The scraper 3 is for scraping off the shit adhering to the surface of the drum 9, and is attached so that its tip is slightly in contact with the outer peripheral surface of the drum 9. Further, the scraper 3 is desirably made of a material that is non-magnetic and resistant to wear due to long-term use, such as austenitic stainless steel, so that shots are not attracted to the scraper 3 itself. The scraper 3 is fixed to the frame 6, but as the drum 9 rotates as the main body of the cleaning machine moves, the scraper 3 is fixed to the frame 6.
The tip of the drum 9 will rub against the outer peripheral surface of the drum 9.
This is due to the fact that the shot adsorbed to the surface is scraped off.

Further, the receiving box 4 is detachably provided under the scraper 3 so that the shot scraped by the scraper 3 falls downward due to gravity and is automatically stored in the receiving box 4. The receiving box 4 is also preferably made of a non-magnetic material, and in this embodiment, it is made of aluminum and is capable of storing about 3 kg of recovered shot. Once the receiving box 4 is full, the shots can be easily removed and collected.

In this embodiment, unlike the first embodiment, no front wheels or gears are provided, but seven langes 13, which also serve as wheels, are fixed to both ends of the drum 90 to rotatably support the drum 9. This flange 1
3 is in the shape of a wheel, and has a diameter slightly larger than that of the drum 9. Therefore, this flange 13 rotates in direct contact with the ground, and the suction surface of the drum 9 rotates in a state slightly floating above the ground.

The shot collecting and cleaning machine of the present invention rotatably supports the drum by connecting the front drive gear and the drum, or by providing the drum with a flange that also serves as a wheel, and includes a permanent magnet in the drum. Furthermore, a scraper and a receiving box were provided to scrape off the shot adsorbed on the drum. For this reason, it has become possible to easily adsorb and recover even objects such as shot, which each have a small surface area and are heavy. Furthermore, since scraping and storage can be performed automatically as the cleaning machine runs, it is possible to use the cleaning machine continuously without interrupting the collection work, making the collection work even more efficient.
