[0001]

[Industrial applications]

 The present invention relates to a crushed stone sorter that sorts stones crushed in a quarry according to size.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, it has been known that rocks crushed in a quarry are selected by rocking a rocking sieve having a sieve inside.

[0003]

[Problems to be solved by the device]

 As described in the prior art, when crushed stones are sorted using an oscillating sieve, the mesh of the sieve may be clogged with crushed stones, and the sorting operation cannot be performed efficiently. There was a problem that it was difficult to deal with various uses of crushed stone because it was possible to select only two different sizes.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a crushed stone sorter capable of performing various types of sorting without clogging. To do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a device that cooperates with a conveyor that conveys crushed stones and sorts by size of the crushed stones. In the device, the front is a steel fine mesh portion and the rear is a steel coarse mesh portion. Connect them together, insert the central shaft from the rear to the connecting part of the steel coarse mesh part and the steel fine mesh part, project the hopper inlet at the center of the circle on the circular front end face, and attach the circular rear end face. The hollow rotary body for sorting, which is opened, and the front and rear ends and the end of the center shaft, which are adjacent to the conveyor for crushed stone transportation in an inclined state in which the front end of the rotary body for sorting is higher than the rear end, Each pedestal rotatably supported around the central axis, a motor drive device equipped with a chain wound around the circumference of the front end portion of the sorting rotary body, and each mesh portion and rear of the sorting rotary body. It consists of three conveyors located directly under the edge, and is a rotating sorting machine. In which the crushed stone in circulation the crushed stone into three types in the halftone portion and rear selection made Betsushite into the fuselage.

[0006]

[Action]

 The rotary body for sorting, which has a steel fine mesh portion and a steel coarse mesh portion and has an open rear end surface, enables sorting of crushed stones into three types.

The rotary body for sorting, which is rotatably supported in an inclined state, causes crushed stones to be thrown in from a high-positioned entrance to naturally roll along each mesh and drop, and rotate the crushed stones meshed in each mesh. Shake off with to prevent clogging.

The hopper entrance projecting at the circular center position of the circular front end face of the sorting rotary body makes it possible to smoothly throw crushed stones into the rotating sorting rotary body without obstacles.

【Example】

 An embodiment will be described with reference to the drawings. As shown in FIG. 1, in a device that works in cooperation with a crushed stone conveyor 17 that conveys crushed stones and sorts the crushed stones according to size, the front is made of steel fine mesh part 6 And, the rear side is integrally connected as the steel coarse mesh portion 7, the steel fine mesh portion side 6 is adjacent to the crushing stone conveyor 17, and the connection portion of the steel coarse mesh portion 6 and the steel fine mesh portion 7 from the rear side. A hollow rotary body 5 for selection is provided through which the central shaft 8 is inserted.

As shown in FIG. 2, the circular front end surface of the rotary body for sorting 5 has a hopper entrance 15 projecting at the center of the circle, and a net is stretched around the hopper entrance 15 to support it with a support material. As shown in FIG. 4, the circular rear end surface of the rotary body 5 is opened only by providing the two support members 10 from the central shaft 8. As shown in FIG. 3, the cross section of the connecting portion between the steel fine mesh portion 6 and the steel coarse mesh portion 7 of the rotary body for sorting 5 has a center axis 8 passing through the center and being radially 3 from the center axis 8. A book support 11 is provided. In a tilted state in which the front end of the rotary body for sorting 5 is higher than the rear end, the front and rear ends and the end of the center shaft 8 are respectively attached to the front end pedestal 1, the rear end pedestal 3 and the central shaft pedestal 9 at the central axis 8. Support rotatably around. Two rollers 2 are arranged on the front end pedestal 1 and two rollers 4 are arranged on the rear end pedestal 3. The hopper 16 is inserted into the hopper inlet 15 while being fixed to the front end pedestal 1.

A chain gear 12 is fixedly installed on the circumference of the front end portion of the sorting rotary body 5, and is wound around a chain gear 12 and a chain gear 13 directly connected to a motor 21 by a chain 14 to drive the motor 21. The rotating body 5 for sorting is rotated by.

A pebbles conveyor 18, a medium stone conveyor 19 and large stones are provided at three locations directly below the steel fine mesh portion 6 and the steel coarse mesh portion 7 of the sorting rotary body 5 and immediately below the rear end of the sorting rotating body 5. The conveyor 20 is arranged.

In this embodiment, the crushed stone conveyed by the crushed stone conveyor 17 is put into the hopper 16, enters into the rotary body for sorting 5 from the hopper inlet 15 in the rotating state, and is fed by the steel mesh portion 6. Small stones are selected and dropped, and medium stones are selected and dropped by the steel coarse mesh portion 7, large stones fall from the rear end of the rotary body 5 for selection, and three types of crushed stones are provided for the pebble conveyor 18 and medium stone, respectively. The sheets are stacked and conveyed on the conveyor 19 and the large stone conveyor 20.

[0014]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Since the rotary body for sorting is rotatably supported, the sorting work can be performed efficiently without the crushed stones clogging the meshes of the steel fine mesh and coarse mesh, and the meshes of different sizes can be used. By connecting the nets, it is possible to select crushed stones of various sizes, and it is possible to support various uses of crushed stones.
