Description

[Detailed description of the invention] Industrial applications This invention relates to a rice huller.

Problems to be solved by the invention - Separately from the supply port with an on-off valve that supplies paddy from the paddy hopper to the de-numbering section, reduced paddy sorted in the sorting section is preferentially and directly supplied to the weighing section. In a rice huller equipped with a supply port that can be opened, when it is desired to suddenly stop the operation of descaling, first close the on-off valve of the supply port that has the on-off valve, and then close the on-off valve of the weighing section. Although the operation is stopped, while the reduced paddy transfer device is operating, reduced paddy will be directly supplied to the demixing section from the other supply port on the reduced paddy side, and at this time, the deweighing section has already been゛If it is not working, there will be a pile of paddy on the hulling section.
Then, when the weighing section is started to operate, there are problems such as jamming due to overload on the stirring section.

Means for Solving the Problem This invention provides a supply port (1) for the reduced paddy that has been sorted and sorted by the ζ sorting section □ in the supply section that supplies the paddy to the de-weighing section, and an open/close valve that can be opened and closed. A stone-reduced paddy trough (4) communicating with the supply port (1) and a mixed rice trough (5) for receiving the mixed rice sorted in the sorting section are provided. ) is provided with a switching valve (6) that allows the reduced paddy to flow down into the mixing rice gutter (5) when the on-off valve (2) is closed. do.

Functions and Effects of the Invention The paddy supplied from the on-off valve (2) of the supply port (3) is removed in the dehulling section, and the reduced paddy sorted in the sorting section is reduced through the "reduction" gutter (4). Supply of paddy 0 (1) The mixed rice that could not be sorted in the sorting section is returned to the sorting section via the mixing rice gutter (5). It turns out.

When you want to suddenly stop the operation of the de-weighing section, if you close the 1 on-off valve (2), the supply of paddy to the de-hulling section is cut off, and the change-over valve (6) operates to reduce the amount of reduced paddy. is the supply port (1)
The paddy flows down into the mixing rice gutter (5) without being reduced to water, and is returned to the sorting section. Therefore, even if the deweighing section is stopped, no paddy is supplied to the dissolution section. Therefore, even if the weighing section is restarted, no jamming or the like will occur.

°In addition, when the on-off valve (2) is opened after starting the deweighing section, the supply of paddy from the supply port (3) to the deweighing section is started, and the switching valve (6) is restored and the reduced paddy is removed. is returned from the reduction line gutter (4) to the supply port (1) and supplied to the deweighing section, resulting in a normal operating state.
