特開昭５５ー１６７０７１号公報Japanese Patent Laid-Open No. 55-167071

収穫した原籾は、わら屑や、砂礫等の異物を多量に混入していることがあり、粗選別装置でこれらの異物を選別除去するために、簡潔的で、高能率の粗選別処理して、本体として処理目的の籾摺機や、乾燥機等に供給することを要する。このため、粗選別された異物と籾粒とが接近した取出口位置に取出されると、異物が飛散して籾粒選別位置側へ再混入したり、又、選別装置の上網や、下網部における選別詰りが発生易いために、これらに対処するためのメンテナンス作業に長時間を要すること多い。 Harvested raw straw may contain a large amount of foreign substances such as straw scraps and gravel. In order to sort and remove these foreign substances with a coarse sorter, a simple and highly efficient coarse sorting process is performed. Therefore, it is necessary to supply the main body to a rice huller for processing purposes or a dryer. For this reason, when the roughly sorted foreign matter and the soot are taken out to the close exit position, the foreign matter is scattered and mixed again to the side of the soot sorting position, and the upper and lower screens of the sorting device Therefore, the maintenance work for dealing with these often requires a long time.

An air funnel 15 is formed that swings by a crank mechanism 19 and forms an induction funnel 10 that feeds the housed raw material at the top of the gantry 1 and a sorting air passage 11 through which suction air is passed by a suction blower 12. It is equipped with.

本実施の形態では、上網３の搬送終端側（下網４の搬送始端側）を前側、上網３の搬送始端側（下網４の搬送終端側）を後側と呼ぶ。
前記揺動棚枠２には、目抜盤形態の上網３と下網４が、上下二段棚の形態に配置されて、上網３は、後端部側を高位置にし、前端部側を低位置にするよう前下り傾斜面に設け、この下側の下網４は、前記上網３の傾斜方向とは逆向傾斜となる後下り傾斜面に設けている。従って、これら上網３、下網４上面に供給された籾は、各々この傾斜面を下り方向へ揺動流下されながらわら屑や、砂礫等を選別する。上網３の下面に摺接するスクレーパ９は、ブラシ２０を固定するホルダ２１を左右の支持枠２２間に亘って取付けたブラシスクレーパの形態として、各スクレーパ７の前後方向の配置間隔Ｃを適宜に設定して、多条、平行形態に配置構成している。 In the present embodiment, the transport end side of the upper network 3 (the transport start end side of the lower network 4) is referred to as the front side, and the transport start end side of the upper network 3 (the transport end side of the lower network 4) is referred to as the rear side.
In the swing shelf frame 2, an upper net 3 and a lower net 4 in the form of a mesh board are arranged in the form of two upper and lower shelves, and the upper net 3 has a rear end side at a high position and a front end side. The lower net 4 on the lower side is provided on the rear down inclined surface which is inclined opposite to the inclination direction of the upper net 3 so as to be in a low position. Therefore, the straw supplied to the upper surfaces of the upper net 3 and the lower net 4 sorts straw debris, gravel and the like while being swung down the inclined surface in the downward direction. The scraper 9 slidably in contact with the lower surface of the upper net 3 is configured as a brush scraper in which a holder 21 for fixing the brush 20 is mounted between the left and right support frames 22, and the arrangement interval C in the front-rear direction of each scraper 7 is appropriately set. And it is arranged and configured in a multi-row, parallel configuration.

ここにおいて、架台１に対して揺動可能に支架する揺動棚枠２に籾の供給を受けて前側へ揺動移送しながらわら屑や、砂礫等を選別する前下がり傾斜の上網３と、この上網３から漏下する籾を受けて後側へ流下移送しながら砂礫などの細異物を漏下選別する後下がり傾斜の下網４と、この下網４から漏下する細異物を受けて前側へ揺動移送させる前下がり傾斜の底板５とを、上下折重状形態にして装着し、前記上網３の前端部から流下するわら屑を排出する三番口６と、底板５前端部から流下する異物を排出する四番口７とを、前記揺動棚枠２の前端部に設け、前記下網４から流下する籾米を排出する一番口８を、揺動棚枠２の後端部に設ける構成とする。 Here, the upper net 3 of the front downward inclination which sorts straw scraps, gravel, etc. while receiving the supply of the basket to the swing shelf frame 2 swingably supported with respect to the gantry 1 and swinging and transporting it to the front side, In response to the dredging leaked from the upper net 3, the fine nets such as sand and gravel are screened out while being flowed down to the rear side, and the lower net 4 falling downward and the fine foreign substances leaking from the lower net 4 are received. A bottom plate 5 which is inclined forward and downward to be oscillated and transferred to the front side is attached in a vertically folded form, and a third port 6 for discharging straw waste flowing down from the front end of the upper net 3 and a front end of the bottom plate 5 A fourth port 7 for discharging the foreign matter that flows down is provided at the front end of the swing shelf frame 2, and the first port 8 for discharging the rice that flows down from the lower net 4 is the rear end of the swing shelf frame 2. It is set as the structure provided in a part.

揺棚動枠２の揺動によって上網３と、下網４、及び底板５を揺動させる。この上網３の傾斜の後端上端部上面に原籾を供給すると、この上網３上面を前端（下端）部へ揺動移送されながら、籾粒や、この籾粒よりも小さいわら屑や、砂礫等異物が、この上網３から下網４面上に漏下され、この上網３上面を前端側へ移送されるわら屑等は、前端部から直下部の三番口６へ流下して排出処理される。前記下網４面に漏下した籾粒等は、この下網４の後端下りの傾斜方向に沿って揺動移送されながら、前記混入の細異物が下網４から下側の底板５面に漏下し、精選された籾粒が後端部から直下部の一番口８へ流下される。前記底板５面に受けた細異物は、この底板５の揺動によって傾斜下端側部、即ち前端部側へ流下されて、この直下部の四番口７へ流下して排出処理される。 The upper net 3, the lower net 4, and the bottom plate 5 are swung by swinging the swing rack moving frame 2. When the raw iron is supplied to the upper surface of the upper end of the rear end of the upper net 3, the upper surface of the upper net 3 is oscillated and transferred to the front end (lower end). Foreign matter is leaked from the upper net 3 onto the lower net 4 surface, and the straw scraps transferred to the front end side of the upper net 3 flow down from the front end to the third port 6 at the lower part and discharged. Is done. The dust particles that have leaked to the surface of the lower net 4 are oscillated and transferred along the direction of inclination of the lower end of the lower net 4 while the mixed fine foreign matter is transferred from the lower net 4 to the lower base plate 5 surface. The finely selected soot grains flow down from the rear end to the first mouth 8 immediately below. The fine foreign matter received on the surface of the bottom plate 5 flows down to the inclined lower end side, that is, the front end side by the swing of the bottom plate 5, and flows down to the fourth port 7 immediately below and is discharged.

前記上網３、下網４から漏下する選別物は、流下方向上手側で受けた選別物をこれらの下側の受板３７、３９で受けて集流しながら、下網４の前端部上面に供給し、又は、底板５の後端部上面に供給して、各下網４面、および底板５面における揺動選別行程を長く形成する形態としているが、このような構成に代えて、直接下網３上面、又は底板５上面に受ける形態とすることも可能である。 Sorted items leaking from the upper mesh 3 and the lower mesh 4 are collected on the upper side of the front end portion of the lower mesh 4 while collecting the collected items received on the lower flow side by the receiving plates 37 and 39 on the lower side. Supply or supply to the upper surface of the rear end portion of the bottom plate 5 to form a long swing selection process on each lower mesh 4 surface and the bottom plate 5 surface, but instead of such a configuration, directly It is also possible to adopt a form that is received on the upper surface of the lower net 3 or the upper surface of the bottom plate 5.

又、前記上網３の下面に摺接するスクレーパ９を前後適宜間隔に配設する。
前記上網３の上面に供給された原籾が、前端部側へ揺動移動されながら、籾粒や、これより小さい細異物等がこの上網３から漏下されて、この上網３上面を前端部へ揺動移送された異物が三番口６へ排出される。このような上網３上面の選別作用では、大きいわら屑や、砂礫等の異物が、上網３の網目に詰り易く、局部的に詰り部を生ずると、選別性能を低下させることになり易いものであるが、この揺動選別作用を行う上網３の下面には、スクレーパ９が摺接して、上網３の網目下面に突出する詰った異物を、削り取って除去したり、上網３上面側へ押し上げて揺動移送作用を行わせる。このように、上網３下面に作用するスクレーパ９は、上網３上面の原籾の揺動移送を抵抗阻害することなく、網目の開口状態や、漏下選別状態を良好に維持して、高能率、高性能の粗選別を行わせる。 In addition, scrapers 9 that are in sliding contact with the lower surface of the upper net 3 are disposed at appropriate intervals in the front-rear direction.
While the raw iron supplied to the upper surface of the upper net 3 is swung to the front end side, the fine grains and smaller foreign matters are leaked from the upper net 3, and the upper surface of the upper net 3 is moved to the front end portion. The foreign matter oscillated and moved to the third outlet 6 is discharged. In such a sorting action on the upper surface of the upper net 3, foreign matter such as large straw debris and gravel easily clogs the mesh of the upper net 3, and if a clogged portion is locally generated, the sorting performance tends to be lowered. However, the scraper 9 is in sliding contact with the lower surface of the upper mesh 3 that performs the rocking selection action, and the clogged foreign matter protruding from the lower surface of the upper mesh 3 is scraped away and pushed up to the upper surface side of the upper mesh 3. The rocking transfer action is performed. In this way, the scraper 9 acting on the lower surface of the upper net 3 can maintain the open state of the mesh and the state of leakage selection well without impeding resistance to the rocking movement of the raw material on the upper surface of the upper net 3. , Perform high-performance coarse sorting.

又、前記上網３、及びスクレーパ９の前端部分を搬送終端部網３Ｆ、及び搬送終端部スクレーパ９Ｆとして、これらの各搬送部網３Ｒ、又は搬送部スクレーパ９Ｒに対して着脱可能、又は起伏回動可能に設け、前記下網４の前端部上面を解放可能の形態とする。 Further, the front end portion of the upper net 3 and the scraper 9 is used as a transfer end portion network 3F and a transfer end portion scraper 9F, which can be attached to and detached from each of the transfer portion networks 3R or the transfer portion scraper 9R or turn up and down. The upper surface of the front end portion of the lower net 4 is releasable.

前記揺動棚枠２の装着された上網３や、スクレーパ９は、一体的に揺動して、この上網３上面に供給される原籾を揺動移送しながら、この原籾の籾粒や、この籾粒よい小さいわら屑や、砂礫等の細異物を、この上網３の網目から下網４面に漏下させ、この上網３上面に残って揺動移送される粗大異物が前端部から三番口６へ流下排出される。このような上網３上面で選別された籾粒や、細異物は、下網４面を後端部側へ揺動移送されながら、籾粒を後端部の一番口８へ取出し、下網４の網目を漏下した細異物を底板５面で受けて前端部の四番口７へ排出させる。このような籾選別作用において、上網３上面にわら屑等が詰ったときは、この上面３上側部を覆う上部カバー等を開いて、上面のわら屑や、砂礫等を取り除く。 The upper net 3 on which the swing shelf frame 2 is mounted and the scraper 9 are integrally swung, and the raw iron supplied to the upper surface of the upper net 3 is swung and transferred, The fine foreign matter such as fine straw dust and sand gravel leaks from the mesh of the upper mesh 3 to the lower mesh 4 surface, and the coarse foreign matter remaining on the upper surface of the upper mesh 3 is oscillated and transferred from the front end. It flows down to No. 3 outlet 6. The soot particles and fine foreign matters selected on the upper surface of the upper net 3 are taken out to the first port 8 at the rear end while the lower net 4 is being oscillated and transferred to the rear end side. The fine foreign matter that has leaked through the 4 mesh is received by the bottom plate 5 surface and discharged to the fourth port 7 at the front end. In such a sorting operation, when the upper surface of the upper net 3 is clogged with straw scraps or the like, the upper cover or the like covering the upper side of the upper surface 3 is opened to remove the upper surface straw scraps or sand gravel.

又、上網３下面や、スクレーパ９等に係合するわら屑が停滞したり、下網４上面にわら屑や砂礫等が詰った場合は、前記上網３前端部分の搬送終端部網３Ｆを揺動棚枠２の搬送部網３から取外したり、この搬送終端部網３Ｆを搬送部網３Ｒに対して上方へ起立回動させて、スクレーパ９の上側面を開放して、前記上網３下面や、スクレーパ９部に詰ったわら屑等を手で取出して取除く。又、このようにして、下網４の前端部上面部をも開放できる形態では、この下網４上面のわら屑等を取除くことができる。又、下網４上面のわら屑等の異物を掃除するときは、前記搬送終端部網３Ｆや、搬送終端部スクレーパ９Ｆを前記搬送部網３Ｒや、搬送部スクレーパ９Ｒから取外し、又は上方へ起立回動させて、下網４前部上面を開放して掃除し易くする。 In addition, when the straw scraps engaged with the lower surface of the upper mesh 3 or the scraper 9 stagnate or the upper surface of the lower mesh 4 is clogged with straw scraps or gravel, the transport end network 3F of the front end portion of the upper mesh 3 is shaken.
