Description

[Detailed Description of the Invention] This invention uses a chain in which egg-shaped links are alternately connected in a perpendicular manner and stretched in an endless manner, and metal materials (cutting chips, metal products, mineral raw materials), Paper products (old newspapers, old magazines, paper waste), wood (wooden products, wood chips, chips), soil (gravel, concrete), leather, rubber, plastic, radioactive materials, poultry, meat, fish and shellfish, grains, various industries The present invention relates to a multipurpose conveyor device capable of conveying materials over a wide range, including materials such as raw materials (solids and powders), snow, garbage, and stone powder.

There have been various types of conveyors using endless chains, but all of them have complicated link structures and are time-consuming to manufacture.

The present invention provides an oval link chain in which oval links, the simplest type of chain, are connected in alternate directions at 90 degrees, which not only has sufficient strength, but also can be easily obtained in various sizes and in the required length. The present invention focuses on this and proposes a conveyor using this.The present invention therefore consists of connecting oval links in an endless tubular passage by alternately changing their directions by 90 degrees.
A multi-purpose conveyor that passes through a chain that is cyclically driven in one direction and conveys material in one direction in a tubular passage by the cyclic drive of the chain. Connecting, top and bottom,
The chain is bent in left and right directions and in a combination thereof, and the peripheral edge of a disk whose diameter is slightly smaller than the inner shape of the pipe of the passage member is fixed at one point at every plurality of links in the chain. Features.

Hereinafter, the present invention will be described with reference to the illustrated embodiments.
The chain 2 is an endless chain formed by connecting 2 orthogonally in an alternating manner, and the chain 2 is an almost endless chain formed by connecting straight pipes 2a of various lengths and short lengths with a constant diameter, and curved pipes 2b by flange connection. passage, 3 is a disk whose straight shape is slightly smaller than the inner diameter of the tube constituting the tubular passage; 4 is an obliquely upward end provided in the tubular passage; 5 is an obliquely downwardly directed end overlapping the above end; Ends shown.

The first embodiment shown in FIGS. 1 to 4 comprises two sets of first and second tubular passages 2-, 2-, with one end and the other end of each of the first and second sets being close to each other, A series of endless chains 1 are passed through both passages. To this chain, a peripheral edge of a disk 3 having a diameter slightly smaller than the inner diameter of the tube is fixed to every plurality of links by welding or the like to form a scraper.

The chain 1 exits from one end 4 of one passage 2, runs toward the drive wheel 6, reverses direction, and enters the other passage 2.
- enters one end 5 of the other passage, exits from the other end 4 of the other passage, passes over the follower wheel 7, reverses direction and enters the other end 5 of one passage 2 -. The scraper is a disc whose diameter is slightly smaller than the inner diameter of the pipe, and part of the periphery is welded to the chain link, so it can be used not only for straight pipes in passages but also for bent pipes such as elbow pipes and bent pipes. The inside of the part can also be moved freely. Therefore, supply ports 8 for conveyed materials are opened at necessary locations in the passages of each group 2-, 2-, and
When objects are fed into the pipe from here, the objects fed into the first passage are discharged from one end 4, and the objects fed into the second passage are discharged from the other end 4, effectively utilizing the entire length of the chain. It can be used to collect transported items in two locations.

Further, in this device, the dumping portions 9 are formed on both sides of the passage, but as in the embodiment described later, the dumping portions 9
The installation location can be freely designed depending on the layout, such as forming it on one side of the aisle.

The second embodiment shown in FIGS. 5 to 7 shows a further development of the above embodiment.

Garbage generated in the kitchen 11 of the building 10 is collected at an outdoor collection point 12 (including processing facilities, transport vehicles, etc.)
This is the case when transporting to.

Specifically, as shown in FIG. 7, it consists of a passage 2 penetrating a wall 13 and a supply port 14 formed in the passage 2, and an endless chain 1 with a disc 3 attached to the passage 2 is installed at an outdoor collection point. By circulating the food waste to 12, it is possible to quickly and hygienically transport the garbage.

In this example, garbage was described as an example, but it is also possible to have products such as department stores collected at a certain location. Further, transporting substances from the ground to the floor below is also included in some aspects of this embodiment.

The embodiments shown in FIGS. 8 to 12 relate to snow removal systems in areas with heavy snowfall. That is, a passage 2 of an appropriate length is buried in the road surface 15, and a supply port 17 having a manhole 16 is provided.
are provided at appropriate intervals, and snow is dumped through this supply port 17 manually or by a machine (snow plow) or the like.

The endless other ends 4 and 5 of the passageway 2 are exposed to the ground, and the chain 1 is driven in circulation by a drive wheel 6 rotated by a motor to temporarily and large quantities of snow through a transport means such as a dump truck. Can be transported.

10 and 11 show a brace 18 formed on the back side of the disc 3 of the endless chain 1 passing through the passage 2.

This brace 18 has one end fixed to the chain 1, and the other end rising diagonally toward the front.
A T-shape that is formed so as to provide a slight distance between the back side of the disc 3 and that is set to have a length that supports the upper end of the brace 18 or more than half of the upper body of the disc 3. It's a brace.

Such a measure serves to support the load applied to the disk 3 that is falling backwards when transporting a material whose volume is reduced and its weight increases, such as snow, or a material that is relatively heavy. can be accomplished.

Next, FIG. 12 is a drawing showing details of the dumping section 19 shown in FIG. It is dumped from the end 4 into the dumping port 20 and circulated through the chain 1 again from the end 5 overlapping the upper passage member 2-. As a result, when the material is dumped from the overlapping end 5 and the chain 1 is drawn in from the underlapping end 4 for circulation, a part of the material dumped from the overlapping end 5 is lowered. It can be completely prevented from entering the end portion 4 that overlaps with the other end portions.

Although this snow removal system is used as an example for transporting snow, it is needless to say that it can also be used as a means of transporting garbage during the snowless season.

Incidentally, in this example, the road width is 8 m, the length is 250 m,
If the snowfall amount is 0.75m/12Hrs, the steel pipe diameter is 0.5m,
If the chain speed is set to 10 m/min to 15 m/min, it is possible to sufficiently transport snowfall for 12 hours.

In this case, the distance between the discs is preferably about 0.5 to 0.7 m. Thus, it is extremely useful as a snow removal system in areas where it is difficult to find a place to dump snow.

By selecting and connecting straight pipes, bent pipes, and elbow pipes according to the supply position of the conveyed material, passages can be freely laid out not only in the horizontal plane but also in the vertical and diagonal directions.

Thus, according to the present invention, it is possible to provide conveyor apparatuses having various structures depending on the objects to be conveyed, using a link chain in which egg-shaped links are connected.
