Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention provides a system in which a sorting cylinder having a large number of potholes formed on the inner circumferential surface is mounted inside a nearly hermetically sealed machine body by means of a plurality of rollers. To facilitate cleaning and inspection of the sorting barrel and the inside of the machine in a pothole type sorting machine that is horizontally supported and rotatably mounted and a receiving gutter is inserted into the sorting barrel and horizontally hung to sort mixed grains. It is an object of the present invention to provide a sorting barrel facilitating device for easily removing the sorting barrel from the aircraft.

(B) Conventional technology As mentioned above, a sorting cylinder having a large number of potholes formed in its inner circumferential surface is supported by a plurality of rollers and is rotatably suspended horizontally, and inside the sorting cylinder. A conventional pothole type sorter that sorts mixed grains by passing through a receiving gutter horizontally supports a sorting cylinder rotatably, as shown in, for example, Japanese Utility Model Application Publication No. 57-55586. The wheels are set to always rotate in a fixed position, and the side surfaces of the wheels come into contact with the flange formed on the surface of the sorting cylinder, restricting movement in the direction of the rotation axis. -ing

Therefore, when attempting to pull out the sorting barrel from the machine, the flange interferes with the wheels, so the sorting barrel cannot be pulled out unless the sorting barrel is lifted and the flange is separated from the bearing surface of the wheels. .

(c) Problems to be solved by the invention In the conventional type, when an attempt is made to pull out the sorting cylinder from the machine body, the flange interferes with the rollers, making it impossible to pull out the sorting cylinder and lifting the sorting cylinder. However, the present invention has disadvantages such as having to remove the flange while separating it from the bearing surface of the roller, which requires a great deal of effort and effort. It was created with the aim of making it easier to insert and remove the sorting cylinder and to make cleaning and inspection of the sorting cylinder and the inside of the machine convenient.

B) Means for Solving the Problems In order to accomplish the above-mentioned object, the present invention includes a sorting barrel having a number of potholes formed on its inner circumferential surface, which is supported by a plurality of rollers in the body of the machine. This pothole type sorting machine is configured as follows in a pothole type sorting machine which is rotatably mounted horizontally and has a receiving gutter inserted into the sorting barrel and horizontally mounted. That is, when the sorting cylinder is constructed to be able to be freely inserted and removed in the direction of the rotation axis of the sorting cylinder, the roller supporting the sliding side of the sorting cylinder can be moved between the supported state and the circumferential surface of the sorting cylinder in this supported state. The structure is such that it can be freely switched between a separated state and a non-supporting state.

(E) Function Since the present invention is constructed as described above, the rollers that rotatably support the sorting cylinder can be freely switched to a non-supporting state in which they are separated from the peripheral surface of the sorting cylinder in a supported state. When inserting and removing the sorting cylinder, it becomes possible to remove and insert the sorting cylinder out of the machine without interfering with the wheels.

A sorting air passage (6) and (γ) are formed on the front side and the rear side, respectively, by communicating with the side, and the falling material from the weighing part (A) is air-sorted in the front side sorting air passage (6). The grains of mixed brown rice and paddy are obtained by removing dust and husks such as rice husks, and the brown rice sorted by the pot-hole type sorter (Q) is air-sorted in the rear sorting air passage (7) to remove waste rice. This is the configuration to remove.

The pothole type sorter (C) has a large number of potholes (8) formed on the inner circumferential surface, and is rotated by being supported by a pair of rollers (9) and a plurality of αQαQ at the front and rear. Two sorting sections (C1) and (C2), in which a receiving gutter (2) and a supply gutter θ3) are inserted and horizontally suspended in a sorting cylinder αη that is movably suspended horizontally, are arranged above and below to create a wind sorting section ◎. It is configured so that the mixed grains of brown rice and paddy obtained on the front side are sorted into brown rice and paddy respectively.

Therefore, to describe the means of communication between the above departments, (14)
) is a mixed grain distribution box, and its lower part is branched, one side is connected to the supply gutter (+9) of the upper sorting section (C1), and the other is connected to the lower side and connected to the supply gutter C11) of the lower sorting section (C2). They are connected to each other, ■) α6) is the brown rice removal gutter, and the brown rice removal gutter (b)) is connected to the upper receiving gutter (□□□), and the brown rice removal gutter α6) is taken out from this brown rice removal gutter ■). It inherits brown rice and communicates with the lower receiving gutter (2), and each sorting section (C1) (C

The paddy scooped up by the hoisting packets (19) distributed evenly on the inner circumferential surface of the lower sorting cylinder (11) is received and returned to the paddy tank (2).

Note that (a) is a drop port that opens at the rear of the upper and lower supply troughs θ3) and supplies mixed grains to each sorting cylinder (1°C).

(21) is a double elevator, which is the front one, which lifts the mixed grains of brown rice and paddy obtained in the wind sorting section 0 to the mixed grain distribution box;
It is the one on the rear side and is designed to take out the finished brown rice from which waste rice has been removed in the wind sorting section (G).

The body of the pothole type sorter (C) is made up of a front wall (B) and a rear wall (Tan) formed of thin iron plates, which are connected to the canopy (Tai) and side plates by pieces, respectively. It is constructed in the form of a closed box.

The above-mentioned upper and lower sorting sections (C1) and (C2) have the same configuration except that the fried grain packets α9) are evenly distributed on the lower sorting cylinder (11) as described above, so the upper and lower sorting sections are different from each other. (C
The details of I) will be described below.

The receiving gutter ((2) and the supply gutter θ3) of this sorting part (C1)
The front side part is supported horizontally on the front wall ml in a cantilever manner, and the rear side part, which becomes the free end, is fixed in one direction to a support plate body formed by cutting out the upper and lower parts of the circular plate body. Each screw conveyor (goods)) installed in the rear, receiving gutter (2) and supply gutter αB)
The shaft end of 2)) is inserted through this support plate body (b) and supported, and serves as the fulcrum shaft (3) of the gate valve (turn) which can freely change its posture.
The oa) end is also supported by the support plate (b).

The rear wall (support)) has a large opening to the extent that the sorting cylinder α (1) can be freely inserted and removed from the body, and a shielding plate C31) is fitted between this opening and the support plate body (b), It is tightened and fixed to the rear wall (T) and the support plate (B) using several knob screws (T), and the support plate (B) is firmly supported via the shielding plate C31).

In addition, the mixed grains are supplied from the falling port (company) to the sorting cylinder (
The rear side of 11J has a melting prevention wall (
83), and a rubber elastic annular body forming a tongue piece is integrally fitted to the inner peripheral edge of this melting prevention wall (83), and a A cylindrical flange (35) is attached to the tongue piece of this example of the elastic annular body, the outer circumferential surface of which is joined and slightly tightened.

In addition, (361 and 叡) are a transparent plate body and an opaque plate body that close the upper and lower notches of the support plate body (27), and (
Reference numeral 881 denotes a cover that covers the shaft end of the screw conveyor μs) and the fulcrum shaft (aOa) end of the gate valve (transfer).

On the lower side of the sorting cylinder a1J, there are a front wall (b) and a rear wall (b), which have a front end and a rear end in the front-rear direction, that is, in the rotational axis direction of the sorting cylinder C11), as in the sorting cylinder (11). 23), and are installed horizontally in parallel to each other, and when horizontally installed, the sorting cylinder α℃ is moved by the front and rear wheels (9)C0) and the sorting cylinder C11).
In the rotatable supported state where the transfer surfaces (11a) and (11b) are supported, the outer peripheral edge of the collar (IIC) and the guide rail (with a small gap between the rows) It is made to last.

The wheel shafts f4-11 and (8) to which L (j is attached) are supported at both ends by the front wall (4) and the rear wall slope, and are Part (8) gear box ■
The rolling wheel shaft (8)) of the lower sorting section (C2) is rotated via the drive shaft taken out from the rotating wheel shaft (w) @6). The Nucle conveyor μs) of each sorting section (C1) (C2)
).

Furthermore, inside each sorting cylinder (11), there is a sensing valve that detects the amount of mixed grains to be supplied to the starting end on the rear side where the mixed grains are supplied and the terminal end on the front side, and a sensing valve that partitions the fluidized bed of the mixed grains into upper and lower parts. This will be explained here because it is equipped with a rectifier plate that circulates the upper layer in the opposite direction to the rotating direction (a) of the sorting cylinder (1 (1)).

(12a) and (121)) are the main body and side plate constituting the receiving gutter ((2); the side plate (12b) is connected to the main body Q2a), and the rotating direction ( stomach)
The upper edge of the main body (12a) keeps the upper end close to the inner peripheral surface of the sorting cylinder α°C, as shown in FIGS. 9 and 10.

The sensing valve part is biased toward the rotating direction (A) of the sorting cylinder (11) and is caused by the thickness and thinness of the layer of mixed grains flowing while exhibiting a falling state, and the sorting cylinder Qη is rotated around the upper end of the support shaft. The arm (18) is attached to the inner circumferential surface of the valve (18) and the fulcrum shaft (SOa) of the gate valve (1) on the front side,
Interlockingly connected via the arm (51), the fulcrum shaft (aOa)
A way (52) for urging the sensing valve to approach the inner peripheral surface of the sorting barrel (11) is attached to the rear end, and this way (52) is inserted into the cover @3). It is stored.

Therefore, if the amount of mixed grains supplied into the sorting cylinder increases or decreases, the sensing valve operates to follow this fluidized bed and moves away from or approaches the inner peripheral surface of the sorting cylinder. ) to adjust the amount of brown rice received into the receiving trough ((2)).

In addition, the above-mentioned current plate (b) is the receiving gutter (the main body of the addition (18B)
and the support arm (&1X54) extended to the back side of the supply gutter α3)
) The lower end and the upper end are swingably connected by a link (55 x 56) that is pivotally attached to the sorting cylinder C1.
1) It is possible to freely change between a gently inclined posture approaching the inner circumferential surface and a steeply inclined posture moving away from the inner peripheral surface. The change from the gentle tilt to the steep tilt and the adjustment of the tilt during this time are performed using five operating levers provided on the front 4AI.

This rectifying plate ■ circulates the upper layer of the fluidized bed with a high proportion of brown rice, giving priority to its filling into the pot hole (8), promoting sorting and improving sorting efficiency. (
The upper edge (4
7a) is adjusted in perspective with respect to the inner circumferential surface of the sorting cylinder α, and the attitude of its inclination is changed. Especially when the water content of the mixed grains is high, by adjusting the slope to the steeper side, the flow velocity on the rectifying plate (b) can be increased and the phenomenon of accumulation inside the sorting cylinder 0 can be prevented. It becomes like this.

Next, the above-mentioned wheel (9) α0 is attached to the wheel shaft field) and -
Each rear end portion of is supported on the rear wall -) by a cam bearing 0. This cam bearing 0 consists of a fitting part (58) and a grip part (59) that can be fitted and rotated on the rear wall (-). ) or the ball bearing (60) fitted into the sea bream, and form protrusions (61X6211) at corresponding locations around the grip portion (59),
This protrusion (61) (6e) protrudes from the rear wall (support) side of the retainable stopper ((2) ((a). Also, as described above, the support surface (10a) of the wheel α@ ) supports the transfer surface (11b) of the sorting cylinder C11) and is rotatable, the outer peripheral edge of the collar (11C) and the guide tray 1v (
7)) The cabinet is designed to have a slight gap (goods), but the height from the transfer surface (nb) to the outer periphery of the collar (UC) is defined as (goods), and the supporting state of the wheel α0 is The distance from the position to the transfer surface (11b) to the unsupported position is [
F], then P>M+f (the above-mentioned wheel shaft field) or the amount of eccentricity to the fitting portion (58) of the decoy is set.

Therefore, when cleaning and inspecting the sorting barrel (11) and the inside of the machine, the sorting barrel 0 must be taken out of the machine, but in that case, the cover must first be removed from the support plate (b). After removing the transparent plate (■) and the opaque plate (-), loosen the knob screws and attach the shielding plate T3+1 to the rear wall (1!3).
When it comes out of the cylindrical 7 lunge) is also taken out and the rear wall (
(translation)) is opened wide. At this time, the receiving gutter (+21, supply gutter θB), gate valve -, etc. come to be supported in a cantilevered manner with the free end side, which is the rear end, integrated with the support plate.

In addition, a sensing valve whose lower end approaches the inner circumferential surface of the sorting cylinder (b) due to the biasing force of the way (52) and a receiver whose upper end is held close to the inner circumferential surface of the sorting cylinder α1). The gutter (former side plate (12b)) can be removed by rotating this side plate (121) as shown by the arrow (b) in Figure 12.
21)) The gate valve -) is tilted toward the supply gutter 03) against the biasing force of way) (52), and in conjunction with this tilting, the sensing valve is rotated as shown by the arrow (c). Both of them move away from the inner peripheral surface of the sorting cylinder C11),
If the operating lever (57) is operated as shown by the arrow), the rectifier plate (b) will be changed to a steeply inclined position and its upper edge (47a)
moves away from the inner peripheral surface of the sorting cylinder α1).

In particular, on the inner circumferential surface of the terminal end of the lower sorting cylinder 0η, fried grain packets 01 for scooping up paddy after sorting are evenly distributed, and the inner diameter of the sorting cylinder aη is narrowed by the fried grain packets 09). There is. That is, the virtual lines shown in FIGS. 9 and 10 indicate the rotation locus (a) of the fried grain packet α9), and the lower end of the sensing valve, the upper end of the side plate (12b), and the rectifying plate (6).
) is wrapped, but as mentioned above, the side plate (12
b) to the sensing valve) and the operating lever (57) to move the rectifier plate away from the inner peripheral surface of the sorting cylinder a, the lapping state will be resolved as shown in Figs. 11 and 12. It is.

In addition, the protrusion (6υ) formed on the grip part (59) of the left and right cam bearings 0 engages with the stopper (68) from above, so that the rolling wheel α0 supports the sorting cylinder (11) and can rotate. If the grip portion (59) is sequentially moved as shown by the arrow (E) from the supported state shown in FIG. The protrusion (62) formed at the corresponding location is held by the stopper (63), and the bearing surface (10a) of the rolling wheel α0) is spaced 0 from the transfer surface (nb) of the sorting cylinder C11) in the supported state. They separate and become unsupported.

(Actually, as shown in Figure 2, the sorting cylinder α°C descends without being maintained in a floating state, but this figure is shown for ease of explanation.) This separated state As the sorting cylinder C11) becomes lower, the flange part (the outer peripheral edge of 11Q is the above-mentioned guide tray 1vfn) H
The receiver is stopped, and at this time there is a gap (A) between the outer peripheral edge of the collar (11C) and the bearing surface (10a) of the rolling wheel Cl0) as shown in FIG.

Therefore, if the rear side of the sorting cylinder (C11) is pulled out backwards, the front side of the sorting cylinder (11) will be removed from the support state by the rollers (9), and the outer peripheral edges of the front and rear flanges (IIC) will be attached to the guide rails ( It slides while being received by the barbs and is taken out of the aircraft.

When inserting this extracted sorting barrel into the machine, place the flange (llc) on the guide tray) v o1)
is restored to its supported state, the shielding plate (311, etc.) is attached, and it becomes operational.

In addition, if foreign substances such as pebbles are mixed into the mixed grains supplied to the sorting cylinder (11), the receiving gutter (2), the supply gutter 03) and the screw conveyor (Foundation)) installed therein should be removed. )
), which may impede its rotation and may even damage the weighing row/L' (8).

In such a case, as a means for removing foreign matter, for example, the 13th
As shown in Figures to Figure 16, a mixed grain tank (66) is interposed between the thrower cylinder (65) for lifting up the mixed grains obtained after deweighing and air sorting and the supply gutter Cl11>, and the mixed grains are collected. tank(
What is necessary is to take measures such as providing a bright line (6f1) in the thrower cylinder (66) for receiving and sieving the mixed grains introduced from the thrower cylinder (65).

The one shown in Figures 13 and 14 has a lid (67) with an opening large enough to pass brown rice and paddy.
68) and from the outlet (68) to the emission line (67) indicates the number of sections from which to remove the foreign matter.
The one in Fig. 5 is configured so that the lid (68) and the bright line (67) rotate together, and the receiver is rotated as shown in the imaginary line when removing the stopped foreign object.
), and Fig. 16 shows a configuration in which a bright line (67) is installed obliquely in the mixed grain tank (66) and foreign matter is taken out from the port (69) while flowing down on this bright line (67). In the figure, (70X71) indicates a vertically installed anti-diffuse reflection plate.

(G) Effects of the Invention As explained above, the present invention has a sorting barrel having a number of potholes formed in its inner circumferential surface, supported by a plurality of roller wheels, and rotatably mounted horizontally in the body of the machine. In addition, in a pothole type sorting machine in which a receiving gutter is inserted horizontally into the sorting cylinder, and the sorting cylinder is configured to be freely inserted and removed in the direction of the rotation axis of the sorting cylinder, the sorting cylinder can be inserted and removed. Since the rollers supporting the sides are configured to be freely switchable between the supported state, the supported state, and the non-supported state in which they are spaced apart from the circumferential surface of the sorting cylinder in this supported state, the sorting cylinder can be rotated in the direction of this rotation axis. When inserting and removing the sorting cylinder, the flange formed on the surface of the sorting cylinder does not interfere with the rolling wheels, making it easy to insert and remove the sorting cylinder without much effort and effort, and cleaning the inside of the sorting cylinder and the body of the machine. This made it possible to make inspections more convenient.
