Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coarse material sorting device used for sorting grains, sorting seeds, separating the bones of boiled and crushed fish, sorting cut burdock root with different diameters, etc.

[Conventional technology]

Most of the conventional sorting devices of this type apply vibration or horizontal motion to a screen, such as a hole or a screen, provided with a fixed sorting space.

[Problem that the invention seeks to solve]

For those equipped with the fixed sorting space,
Not only is the efficiency of sorting poor because the holes, meshes, etc. become clogged and continuous sorting is not possible, but the objects to be sorted are limited to granular materials, and the sorting accuracy also deteriorates.

The present invention eliminates these drawbacks and enables efficient and accurate sorting of various articles.

[Measures to solve problems]

Frame main body 2 equipped with support legs 1 for tilt adjustment
, an internal gear 3 fixed to the frame body 2, a main shaft 5 which is rotatably supported by the frame body 2 with a rotary support plate 4 pivotally attached to both ends, and a small gear 6 is pivotally attached to the shaft end. A large number of sorting bars 9 each having a large diameter shaft part 7 and a small diameter shaft part 8 formed in stages.
and a collection mechanism section 10 that is located below these sorting bars 9 and collects the sorted products separately, and a collection mechanism section 10 that is located below these sorting bars 9 and collects the sorted items separately. A rotary support plate 4 is supported at predetermined intervals on its peripheral edge to form a sorting rotary cylinder 11, with the mouth 13 of the supply section 12 facing into the inclined upper part of the rotary sorting cylinder 11, and the main shaft 5 or a rotary support plate 4 fixed to the main shaft 5. The gist of the present invention is a coarse material sorting device characterized in that rotational driving force is transmitted to the fine material sorting device.

[Example] In the illustrated example, the inclination adjusting support leg 1 is made by screwing a threaded rod 15 into a nut part 14 fixed to the bottom of the frame body 2, and is placed opposite to the upper frame part of the frame body 2. A bearing portion 16 is provided, and this bearing portion 16
A main shaft 5 with rotary support plates 4 pivotally attached to both ends thereof is rotatably supported, and a large number of sorting bars 9 are provided along the peripheral edge of the opposing rotary support plate 4 at predetermined intervals and with their axes parallel to each other. are pivoted across the bridge to form a sorting rotary cylinder 11, and the sorting bar 9 is composed of a large diameter shaft part 7 and a small diameter shaft part 8, and one end shaft part of each of the many sorting bars 9 is attached to a rotary support plate. 4
An example is shown in which a small gear 6 is pivotally attached to these projecting from the outer surface thereof, and the small gear 6 is meshed with an internal gear 3 fixed to the frame main body 2.

Further, power is transmitted to the main shaft 5 by a sprocket 17 being pivotally attached to the shaft end of the lower inclined portion via a bearing 16, and a chain 19 transmitting the rotational power of the drive motor 18.

Furthermore, the opening 13 of the supply section 12 is connected to the sorting rotary cylinder 11.
(1st
) and when the internal gear 3 is fixed to the frame main body 2 at the lower part of the inclination, the guide tube 20 is fixed to the rotation support plate 4 at the upper part of the inclination and rotated together with the rotation support plate 4 (Fig. (Fig. 3), the collection mechanism section is a first collection section 23 consisting of a first hopper 21 and a first conveyor 22 below it.
and a second collection section 26 consisting of a second hopper 24 and a second conveyor 25 that receives the second hopper 24 (FIG. 1).

Incidentally, between the large diameter shaft part 7 and the small diameter shaft part 8 of the sorting bar 9, an intermediate diameter shaft part is formed to form several stages of sorting gaps, and the objects to be sorted are sorted into several types. In some cases. In this case, the collection mechanism section must be divided into sections corresponding to the stages, and a hopper must be installed along the lower circumferential surface of the sorting rotary cylinder 11.

[Operation and effect of the invention]

The apparatus of the present invention configured as described above adjusts the inclination adjustment support leg 1 provided at the lower part of the frame body 2, and adjusts the inclination angle of the sorting bar 9 so that the upper part of the inclination becomes the large-diameter shaft part 7 according to the object to be sorted. The sorting bar 9 that forms the sorting gap is driven by a small gear 6 and an internal gear that are integrally connected to the sorting bar 9. 3, it becomes a planetary gear mechanism and revolves around the main shaft 5 while rotating on its own axis. Because the structure is tilted and rotates in the same direction,
The supplied objects to be sorted are separated by their own weight and sorting rotary cylinder 1.
1 and the sorting bar 9, and in this movement process, the large diameter shaft portion 7
Fine particles fall downward from the narrow sorting gap between them, and coarse particles move without falling to the wide sorting gap between the small diameter shaft parts 8, then fall from this sorting gap and are collected by their respective hoppers. be done.

In this way, since the sorting bars rotate in one direction while revolving, even if objects to be sorted get stuck in the gap between the sorting bars, the rotational force of the adjacent sorting bars will push them upward. It acts to lift it up and move it to an adjacent gap, without forcing it to fall. Therefore, the clogging of the sorting gap with objects to be sorted is eliminated, and continuous and efficient sorting with high sorting accuracy can be performed without causing an operation stoppage.

Furthermore, since it is cylindrical as a whole, a large amount of sorting processing can be accomplished with a relatively small device, and it is also economical in terms of transportation and installation space.

Incidentally, a typical grain to be sorted is soybean, and grain size and half-split grains are sorted out. In this case, it is recommended to provide a shaft with an intermediate diameter between the large-diameter shaft and the small-diameter shaft so that the half-split product can be dropped first, then the small beans, and then the large beans. It's convenient.

In addition, in the case of sorting cut burdock rootlets of different diameters, it is required to keep the boiling time constant and for the sake of good appearance when serving food.
The distance between the large diameter shaft part and the small diameter shaft part or the intermediate diameter shaft part is determined based on the maximum diameter of the cut burdock root.
