Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mushroom sorting apparatus suitable for sorting mushrooms such as shiitake mushrooms by size.

[0002]

2. Description of the Related Art Generally, an underframe-shaped frame, a rotary shaft which is supported by the frame in an inclined state and is driven to rotate by a rotary source, and the rotary shaft which rotates integrally with the rotary shaft. A rotary drum which is composed of a cylindrical body arranged coaxially and has an inlet with a lid for throwing mushrooms to be sorted on the upstream side, and a hole diameter on the peripheral surface of the rotary drum which is located on the downstream side from the upstream side. A mushroom selection device comprising a large number of large holes and a selection hole for selecting the size of mushrooms introduced into the rotary drum is known from, for example, Japanese Utility Model Laid-Open No. 3-59077. There is.

And, in such a mushroom sorting device,
First, an operator opens a lid part of a loading port with a lid of a rotary drum, and loads mushrooms to be sorted into the sorting drum from the loading port. Then, after closing the lid of the charging port, the rotary drum is manually driven to rotate via the rotary shaft. As a result, the mushrooms in the rotary drum move from the upstream side to the downstream side due to the inclination of the rotary drum, fall to the outside from each sorting hole according to the diameter of each sorting hole, and sort into each size. To be done.

[0004]

By the way, in the mushroom sorting apparatus according to the above-mentioned prior art, when the mushrooms are fed into the rotary drum, the mushrooms to be sorted are loaded with the lid portion of the lid-equipped opening opening. Therefore, it is necessary to stop the operation of the mushroom sorting device each time it is charged. As a result, there is a problem in that not only the operation of the mushroom sorting device becomes intermittent, but also mushrooms have to be thrown in manually every time, resulting in a decrease in workability and a significant decrease in productivity. is there.

Since most of the mushrooms to be sorted have an umbrella having a substantially circular shape, the mushrooms roll at a stretch from the upstream side to the downstream side of the sorting drum at the time of loading into the sorting drum or at the time of sorting. There is a problem in that the mushrooms may move and pass through the sorting holes that should be dropped, which lowers the sorting accuracy of the mushrooms and significantly reduces the reliability.

Further, since many mushrooms are composed of an umbrella portion and a handle portion extending from the center of the umbrella portion with an unspecified curvature, the handle portion may be caught in each sorting hole during sorting. However, there is a problem in that the selection efficiency is reduced and the productivity is significantly reduced.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide a mushroom sorting apparatus capable of continuously sorting mushrooms and improving sorting accuracy at the time of sorting. To do.

[0008]

In order to solve the above-mentioned problems, the structure adopted by the present invention is an underframe-shaped frame,
A supply mechanism that is mounted on the frame and sequentially supplies mushrooms to be sorted, a rotation shaft that is supported by the frame in an inclined state, and is driven to rotate by a rotation source, and that rotates integrally with the rotation shaft. A rotary drum having a cylindrical body arranged coaxially with the rotary shaft and having an inlet on the upstream side for receiving mushrooms sequentially supplied from the supply mechanism; and an upstream drum located on the peripheral surface of the rotary drum. Located between the rotary shaft and the rotary drum, and a large number of holes are provided on the downstream side of the rotary drum to select large and small mushrooms supplied into the rotary drum. A plurality of retaining plates are provided in the state of being separated from each other in the axial direction and being displaced from each other by a predetermined angle in the circumferential direction. The opposite of the rotating drum Comprising a re-sorting mechanism for re-sorting the mushrooms caught on each sorting hole by rotation driven thing.

[0009]

With the above construction, the mushrooms are sequentially supplied into the rotary drum through the receiving port by the supply mechanism, and the mushrooms are continuously large by the selection holes formed in the peripheral surface of the rotary drum.
Small selection. Further, the mushrooms thrown into the rotary drum are prevented from being erroneously sorted by the retention time provided by each stagnation plate, and when caught in each sorting hole, dropped into the rotary drum by the re-sorting mechanism and again Sorted by the sorting hole.
