[Industrial applications]

 The present invention is a process of feeding small grains such as rice grains, broken rice, and grass seeds, which are contained in the grains to be sorted, in the process of feeding the grains to be sorted, which have been removed by a huller, to a sorting plate. A rice hull sorter with which the sorting capacity of the sorting plate is remarkably improved by promptly sorting and removing with a plate and then directly discharging it to the outside or mixing it with brown rice and supplying it to the next grain sorting machine. The present invention relates to a device for removing small particles and the like.

[0002]

[Prior Art]

 Conventionally, the grain removed from the huller is fed to a mixed rice tank, and then the grains to be sorted are sequentially stacked in a stack in multiple stages through a uniform feed gutter and a feed casing. The brown rice, mixed rice, and paddy that are supplied to the supply side of the plate and sorted are discharged from the brown rice discharge gutter, mixed rice discharge gutter, and paddy discharge gutter arranged on the discharge side of the selection plate. Machines are well known without being illustrated prior to this application.

[Problems to be solved by the device]

 By the way, in this kind of hulled rice sorting machine of the past, a large amount of small grains such as small rice, broken rice, and grass seeds were contained in the depleted grains stored in the mixed rice tank. When the grains to be sorted are supplied as they are to the multi-stage sorting plates through the uniform supply trough and the feeding casing, respectively, and the sorting action is performed, small grains and the like are all displayed on the sorting plate during the sorting operation. It is deposited on the lower part of the periphery of a large number of swelling-shaped sorting protrusions that are approximately evenly spaced over the surface, and this significantly reduces the sorting ability, and the grains to be sorted become brown rice, mixed rice, and paddy. There was a problem that it was not possible to select accurately.

The present invention has been made in view of the above problems of the prior art, and the purpose thereof is to supply the mixed rice tank and to flow it through the uniform supply trough. , Small grains such as small rice, crushed rice, grass seeds, etc., which are contained in a large amount in the degrained grain are removed by the grain size selection plate and discharged directly to the outside of the machine, or brown rice is discharged by switching the switching shutter. The present invention intends to provide a device for removing small particles and the like in a hulling and sorting machine, in which the sorting ability of the sorting plate is remarkably improved by discharging the particles.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the removing device for small grains and the like in the hulling and sorting machine of the present invention puts the grains to be sorted discharged from the mixed rice tank into the uniform supply trough into a stack of multiple stages through the supply casing. Brown rice, mixed rice, and paddy obtained by supplying and sorting to the supply side of each stacked sorting plate are the brown rice discharge gutter, mixed rice discharge gutter, and paddy discharge placed on the discharge side of the selection plate. In each of the gutters discharged from the gutter, a small particle discharge gutter having a particle size selection plate stretched is disposed on the upstream side of the uniform supply gutter.

In the middle of the small grain discharge gutter, a connection window that is opened by the switching operation of the switching shutter and connects the small grain discharge gutter and the brown rice discharge gutter is opened.

[0007]

[Action]

 The grains to be sorted that have been removed by the huller are stored in a mixed rice tank. Next, the multi-stage sorting plate integrally provided with the uniform supply trough and the supply housing is eccentrically rotated, and at the same time, the grains to be sorted in the mixed rice tank are discharged onto the eccentrically rotated uniform supply trough. . By the way, in the process in which the grains to be sorted are supplied to the supply casing along the uniform supply gutter, small grains such as small rice, broken rice, grass seeds, etc., which were mostly contained in the grains to be sorted, etc. Is screened by a particle size selection plate, falls into a small particle discharge gutter, and is discharged outside the machine as it is. On the other hand, the grains to be sorted, from which small grains and the like have been sorted out, are fed from the feed casing to the feed side of the sorter plate, respectively, and then pushed up to the discharge side to push up the sorting protrusions. Then, brown rice is sunk in the lower layer, and paddy is floated in the upper layer. Therefore, while the grains to be sorted are transferred from the supply side to the discharge side on the sorting plate, they are sorted into three layers, a brown rice layer, a mixed rice layer, and a paddy layer. At the same time as being supplied to the machine, the mixed rice is supplied to the mixed rice tank again after passing through the mixed rice discharge trough, and the paddy is returned to the paddy machine through the paddy discharge trough and is removed.

By the way, during the above-described sorting operation, there may be a case where it is desired to mix the small grains or the like discharged outside the machine along the small grain discharge gutter with brown rice and supply the mixed rice to the next-stage grain sorting machine. In such a case, if the switching shutter is switched from the solid line position in Fig. 2 to the chain line position, the connection window is opened and the small grain discharge gutter and the brown rice discharge gutter are in communication with each other, and the small grain etc. It is dropped into the brown rice discharge gutter through the connection window.

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Grain to be sorted discharged from the mixed rice tank to the uniform feed trough is supplied to the feed side of each of the sorting plates that are sequentially stacked in a multi-tiered stack through the feed casing, and the grain is obtained. Mixed rice and paddy are discharged from the brown rice discharge gutter, mixed rice discharge gutter and paddy discharge gutter arranged on the discharge side of the selection plate, respectively. Even if it contains a lot of small grains such as, etc., in the process that the grains to be sorted flow down along the uniform supply gutter, they are removed by the grain size selection plate and discharged to the outside of the machine through the small grain discharge gutter to the selection plate. Perhaps it is possible to remarkably improve the sorting ability by eliminating the supply of the small grains, etc., and the small grains can be discharged together with the brown rice from the brown rice discharging gutter through the connection window at any time by the switching operation of the switching shutter.
