[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stone remover for separating foreign matter such as pebbles, metal pieces, and glass pieces mixed in grains from the grains.
[0002]
[Prior art]
Conventionally, a stone remover has been used to separate foreign matter such as pebbles, metal pieces, glass pieces and the like mixed in grains from the grains.
[0003]
An example of a conventional stone removing machine will be described. As shown in FIG. 5, a wind chamber 105 having an impeller 105 a is provided in a box-shaped machine casing 101, and the wind chamber 105 is swung by a swing mechanism 107. The sorter 102 is swingably supported by the ridges 107a and 107b, and the sorter 102 is detachably attached to the open portion above the wind chamber 105, in order to release the grain at the left end of the sorter 102 shown in the figure. The opening 102 a is provided with an on-off valve 103 urged so as to be always closed by a spring 109. When the sorting panel 102 is attached to the open portion of the wind chamber 105, the lever 103 a of the on-off valve 103 is provided. Is pressed by the upper edge portion 104a of the grain discharge cylinder 104, and the opening / closing valve 103 is pivoted and opened against the elastic force of the spring 109 with the support shaft 103b as a fulcrum. Opening It is configured to be discharged to the grain discharge tube 104 from 102a.
[0004]
In the stone remover, the grain introduced from the hopper 101a mixed with the foreign material falls onto the swinging sorter 102, and the air flow generated by the impeller 105a passes through the vent hole 102b of the sorter 102. Then, due to the interaction between the air flow ejected upward and the oscillating motion of the sorting panel 102, the foreign matter having a specific gravity larger than that of the grain is conveyed to the foreign matter discharge tube 108 side, and is discharged to the outside through the foreign matter discharge tube 108. After being discharged, the grain flows down to the opening 102a side and is discharged from the grain discharge tube 104 to the outside.
[0005]
By the way, the grain contains dust in addition to the foreign matter, and the dust clogs the vent hole 102b of the sorting board 102 and lowers the sorting efficiency. It is necessary to pull it out in the direction of the arrow and clean it. At this time, the lever 103a of the on-off valve 103 is separated from the upper edge 104a of the grain discharge tube 104, and the on-off valve 103 is moved by the elastic force of the spring 109. Therefore, the remaining grain can be prevented from falling into the wind chamber 105 (Japanese Patent Publication No. 6-61534).
[0006]
[Problems to be solved by the invention]
However, in the above conventional technique, the sorter has to be moved and pulled out in the longitudinal direction, and it takes time to pull out, and even if the on-off valve is completely closed, the sorter is inclined at a steep angle. Residual grain may fall. In addition, when inspecting the sorter, there is a problem in that the upper part and the side part of the sorter are closed, and therefore the stone remover must be disassembled.
[0007]
The present invention has been made in view of the above-described problems of the prior art, and can be easily attached / detached and inspected by the sorter, and the grains remaining when the sorter is removed may fall. The purpose is to realize a stone-removing machine without any problem.
