The present invention relates to a sorting facilitating device which aims to improve the efficiency of the sorting operation in the above and facilitate insertion of the sorting cylinder into the body.

(B) Conventional technology As described above, a box-shaped body is provided with a sorting cylinder having a large number of jar holes formed on its inner peripheral surface, supported by a plurality of rolling wheels, and rotatably mounted horizontally. A conventional pothole type sorting machine in which a gutter is inserted horizontally in the sorting cylinder, and wherein the sorting cylinder is configured to be detachable in the direction of the rotation axis of the sorting cylinder, is a conventional technique. As disclosed, for example, in Japanese Utility Model Laid-Open No. 60-132842, the efficiency of the sorting action on the supply side of the grains to be sorted is greatly improved and, in connection therewith, the insertion of the sorting cylinder into the fuselage is facilitated. Is not taken into consideration.

(C) Problems to be Solved by the Invention As described above, in the case of the conventional configuration, the efficiency of the sorting action on the supply side of the grains to be sorted is significantly improved, and in relation to this, Since measures have been taken to facilitate insertion, etc., the present invention realizes the efficiency of the screening action of the pothole type sorting machine by embodying these measures, especially on the supply side of the grains to be sorted. The present invention has been proposed for the purpose of effectively refluxing the fluidized bed of No. 1 to promote the selection and facilitate insertion of the selection cylinder into the body.

(D) Means for Solving the Problems The present invention intends to take the following means in order to achieve the above object.

That is, a sorting cylinder having a large number of jar holes formed on its inner peripheral surface is rotatably supported horizontally by a plurality of rolling wheels, and a gutter is inserted horizontally in the sorting cylinder. In the jar-hole type sorting machine, the sorting cylinder is configured so that it can be inserted and removed in the direction of the axis of rotation of the sorting cylinder. A sorting facilitator that is positioned and inclined in the direction of rotation so as to come close to the inner peripheral surface of the sorting cylinder, and keeps the sorting promoting member supply side of the sorting target particles away from the inner circumferential surface than the discharging side. It is constructed by being installed obliquely from the supply side to the discharge side.

(E) Action Since the present invention has taken such means, when the grain to be sorted, for example, mixed rice of brown rice and paddy is supplied to sort the brown rice and the paddy, the rotation of the sorting drum The upper layer with a high proportion of brown rice in the fluidized bed, which shifts to the direction side while exhibiting the state of sedimentation and moves to the discharge side, is refluxed to the jar hole by the sorting promoting member to recirculate from the fluidized bed. The brown rice is preferentially fitted into the rice, whereby the sorting action is efficiently performed. However, the fluidized bed formation state is gradually reduced toward the discharge side where the supply side is large and the sorting action proceeds. As the fluidized bed changes from large to small, the above-mentioned sorting promoting member is installed obliquely from the supply side to the discharge side, and the upper layer of the fluidized bed is evenly circulated. The selection is facilitated by making the reflux effective.

Also, when the sorting cylinder is removed from the machine body and then inserted again into the machine body, the supply side of the sorting facilitating member is set so as to be distant from the inner peripheral surface of the sorting cylinder, so that the inner peripheral edge of the end portion of the sorting cylinder is The lower side is slidably brought into contact with the rear surface side of the selection promoting member and guided downward to reach a predetermined position, so that the insertion can be easily performed.

By the scooping action of the pot hole (12), which is dropped from the drop port (15) to the inner peripheral surface of the selection cylinder (13) and rotates as shown by the arrow (a) in FIGS. 5 and 6. The brown rice fell into the receiving gutter (16) and was sent to the front side, then passed through the brown rice gutter (17) and led out to the rear part of the wind selecting section (B), and scrap rice was removed in the wind selecting path (18). Brown gutter (19) extending into the horizontal transfer case (b) on the rear side
From there, the inside of the rear room of the elevator (D) is lifted and taken out to a proper place outside the machine.

In addition, the paddy left behind from the unpolished rice is several buckets (20) equally distributed on the inner peripheral surface of the sorting cylinder (13) at the front end, that is, the discharge end.
The paddy is lifted up and dropped to the upper side, and the falling paddy is received by the reduction gutter (21), returned to the paddy tank (2), and supplied again to the derolling (3). (22) is the wind selection route
The waste rice pick-up gutter horizontally provided in the rice road portion of (18) extends in the horizontal feed case (a) on the front side in a step difference from that of the mixed rice pick-up gutter (7).

What cannot be scooped up to the receiving gutter (16) due to the scooping action of the pot hole (12) falls into the transfer gutter (14) and joins with the new mixed rice, and from the drop port (15). It is supplied again to the inner peripheral surface of the sorting cylinder (13) and circulates.

The body of the jar-hole sorter (c) is formed of a thin iron plate in a box shape, and the receiving gutter (16) and the transfer gutter (14) are supported by a cantilever type by attaching the front side, that is, the discharge side to the body. The rear side portion that is laterally installed in the front-rear direction and serves as a free end has a support plate body (2
3), the shaft ends of the screw conveyors (24) and (25) that are integrally connected to the gutter (16) and the transfer gutter (14) are inserted and supported by the support plate (23). In addition, the end of the fulcrum shaft (27) of the sluice valve (26) whose posture can be changed is also supported by the support plate (23).

The rear side of the body of the jar-type sorter (c) has a large opening (28) to the extent that the sorting cylinder (13) can be inserted and removed outside the body, and this opening (28)
The support plate (23) is fitted between the support plate (23) and the shield plate (29) and is tightened and fixed to the rear side and the support plate (23) with several knob screws (30). ) Is firmly supported via a shield plate (29).

Further, the rear side of the sorting cylinder (13) to which the mixed rice is supplied is bent at the end periphery thereof to form an overflow prevention wall (31), and the overflow prevention wall (31) has an inner periphery made of rubber. The elastic annular body (32) is fitted on the inner surface of the shielding plate (29).
A cylindrical flange (33) whose outer peripheral surface is joined to 2) is attached.

Incidentally, (34) and (35) are a transparent plate and an opaque plate that closes the upper and lower notches of the support plate body (23), and (36) is the shaft end of the screw conveyor (24) (25). This is a cover for covering the end of the fulcrum shaft (27) of the gate valve (26) and the like.

The sorting cylinder (13) has a pair of front and rear wheels (37) (37).
And (38) and (38) are supported by a plurality of wheels and are horizontally rotatably mounted, and the wheels (37) (37) and (38) (38) are attached to the wheel shaft (3
9) and (40) on one of the wheel shaft (40), the transmission shaft (42) transmitted from the drive shaft (41) taken out from the gear box of the disengagement section (A) is connected by the shaft coupling (43). Combined and jar type sorting machine
It is transmitted to the (C) side.

Further, in the sorting cylinder (13), in the direction of the arrow (a) and the sensing valve (44) for knowing the mixed rice supplied from the rear side and the rear side to which the mixed rice is supplied and the front side. Rotating sorting cylinder (13)
Of the fluidized bed of mixed rice that moves toward the front side while being deflected toward the direction of rotation of the mixed rice and flowing to the front side, separating the upper and lower layers of the mixed rice from the upper layer and rotating the sorting cylinder (13) Sorting promoting members (45) are provided in the direction opposite to the above direction so as to cause the fluidized bed to reflux more.

This sensing valve (44) has a support shaft (4
6) is attached to the inner peripheral surface of the sorting cylinder (13) freely as a shaft, and the support shaft (46) and the fulcrum shaft (27) of the sluice valve (26) are attached to the front side via a link mechanism. Interlocking connection, fulcrum shaft (27)
At the rear end, a weight (47) for attaching the sensing valve (44) to the side closer to the inner peripheral surface of the sorting cylinder (13) is attached, and this weight (47) is inside the cover (36). It is stored. Further, swash plates (48) that serve to feed the mixed rice forming a fluidized bed to the front side are arranged at equal intervals on the working surface corresponding to the inner peripheral surface of the selection cylinder (13) of the sensing valve (44). .

As a result, if the amount of mixed rice supplied to the sorting cylinder (13) increases or decreases, the sensing valve (44) follows the thickness of the fluidized bed to select the sorting cylinder (13).
The sluice valve (2
The posture of 6) is changed to adjust the amount of brown rice received into the trough (16), and the mixed rice that is refluxed by the swash plate (48) in the upper layer of the fluidized bed is fed to the front side.

(16a) and (16b) are a main body and a side plate that form the receiving side gutter (16), and the side plate (16b) is connected to the main body (16a) and the lower end is a fulcrum in the rotation direction of the selection cylinder (13). It is possible to tilt in the opposite direction.

The sorting promotion member (45) is fixed to the lower end of a plate (49) which is hung from the lower surface of the transfer gutter (14) and is displaced toward the rotation direction side of the sorting cylinder (13) indicated by the arrow (a). A plate-like object which is inclined in the direction of rotation and is provided close to the inner peripheral surface of the selection cylinder (13), and the selection promotion member (45) is bent in the reverse shape and is rearward. Keep the supply side closer to the part from the inner peripheral surface of the sorting cylinder (13) than the discharge side closer to the front side, and make the distance (L) from this inner peripheral surface larger than (l) from the supply side to the discharge side. It is installed obliquely toward.

Therefore, this sorting promotion member (45) is indicated by the arrow on the sorting cylinder (13).
As shown in (a), slide the upper one (45a) of the upper layer with a high proportion of brown rice in the fluidized bed that moves while moving to the front side, that is, the discharge side while being displaced in the direction of rotation and rising. It is refluxed rather than the fluidized bed to give priority to the intrusion of brown rice into the jar (12), and the sorting action is efficiently performed to promote this.

In this case, in the formation state of the fluidized bed, the supply side near the rear side is thick and large, and the discharge side of the front side becomes thin and small as the sorting operation progresses. Since the interval (L) is obliquely set so as to be larger than the interval (l) on the discharge side, the sorting promoting member (45) is so-called brown rice in the upper layer over the whole in such a manner that the fluidized bed is formed. The rice with a high proportion of is uniformly flowed back, and further the brown rice is inserted into the jar (12) with priority, and the sorting action is promoted.

Below the sorting cylinder (13), guide rails (50) and (51) are fixed to the sorting cylinder (13) in the front-rear direction so that the front end and the rear end of the sorting cylinder (13) are fixed to the machine body in parallel. In the horizontal state, the sorting cylinder (13) is supported by the front and rear wheels (37), (37) and (38) (38) and is rotatable. There is a slight gap from the outer peripheral edges of the collar portions (52) (53) formed in the front and rear portions.

Therefore, when pulling out the sorting cylinder (13) from the fuselage, first remove the cover (36) from the support plate (23) and clear the transparent plate (34).
And opaque plate (35) and loosen the knob screw (30) to shield
When (29) is removed, the cylindrical flange (33) is also removed and
As shown in the figure, the rear side of the machine body is largely opened (28). At this time, the gutter (16), the transfer gutter (14), the sluice valve (26), etc., are supported in a cantilevered manner by the free end side, which is the rear side, being integrated with the support plate (23). .

Therefore, by the biasing force of the weight (47), the sensing valve (44), which is in a state of approaching the inner peripheral surface of the sorting cylinder (13), and the upper end are kept in a state of approaching the inner peripheral surface of the sorting cylinder (13). Gutter (16) side plate (16
b) If this side plate (16b) is tilted as shown by the arrow (b), the gate valve (26) is tilted against the biasing force of the weight (47) by the weight of this side plate (16b). In conjunction with this, the sensing valve (44) moves upward to the state shown in FIG. 8 and both move away from the inner peripheral surface of the sorting cylinder (13).

In this state, when you insert your hand through the opening (28) and lift the rear side of the sorting cylinder (13) slightly and pull it out, the collar (52) on the front side slides on the upper surfaces of the guide rails (50) and (51). It can be taken out while moving, and it looks like the state shown in FIG.

Next, when inserting the removed sorting cylinder (13) into the original state, insert the sorting cylinder (13) through the opening (28) and guide rail (50).
(51) Slide the collar (52) over and insert it.
Since (44) is moving upward as shown in FIGS. 8 and 9, it is inserted into the lower side of the sensing valve (44) by itself, and then the sorting promoting member (45) is also bent in the reverse shape. Since the supply side near the rear side is positioned higher, the lower peripheral side of the inner peripheral edge of the front side of the sorting cylinder (13) is allowed to enter the back side of the sorting facilitating member (45) and shake with this back side. The guide rails (50) and (51) can be guided downward while being in contact with each other, and the guide rails (50) and (51) can be inserted into predetermined positions.

Further, FIGS. 10 and 11 show an application example of the sorting promoting member (45), in which sorting is performed on the discharge side of the so-called sorting cylinder (13) from the front side portion to the front side portion. On the back surface of the accelerating member (45), a plurality of arcuate restriction plates (54) are fixedly attached to the inner peripheral surface of the sorting cylinder (13) at a lower edge at substantially equal intervals. As described above, the regulation plate (54) temporarily stops the mixed rice that flows while flowing from the place where the fluidized bed is thin on the discharge side and becomes small so that good sorting action is difficult to perform. This is for forming an appropriate fluidized bed, and the regulating plate (54) stabilizes the sorting action and prevents the brown rice from being reduced together with the paddy to the part (A).

(G) Effect of the Invention As described in detail above, the present invention supports a sorting cylinder, which has a large number of jar holes formed on its inner peripheral surface, by a plurality of rolling wheels and is horizontally rotatably supported. And a trough-hole type sorting machine in which a gutter is inserted horizontally in the sorting cylinder, wherein the sorting cylinder is configured to be detachable in the direction of the axis of rotation of the sorting cylinder. A sorting facilitating member is provided inside the barrel so as to be biased toward the rotating direction side of the sorting barrel and inclined in the rotating direction so as to come close to the inner peripheral surface of the sorting drum, and the side of the sorting promoting member to which the grains to be sorted are supplied. Is inclined farther from the inner peripheral surface than that on the discharge side and is inclined from the supply side to the discharge side. The sorting facilitating members are installed obliquely according to the formation state in which the fluidized bed that flows while flowing in the stacked state and moves to the discharge side changes from large to small. In particular, the upper layer with a high proportion of brown rice in the fluidized bed is evenly circulated over the whole of this sorting promoting member, so that the reflux is effectively made from the supply side to the discharge side to the jar hole of brown rice. It is possible to promote the selection action by giving priority to the fit-in of.

Also, since the supply side of the sorting promoting member is located farther from the inner peripheral surface of the sorting cylinder than the discharging side and is obliquely provided from the supply side to the discharging side, when the sorting cylinder is inserted from the outside of the machine The lower side of the inner edge of the end part can be easily inserted into the back side of this sorting promoting member, and it can be slidably contacted with the back side to guide it downwards to reach a predetermined position for easy insertion. It can be
