Description

[Detailed explanation of the invention] (a) Industrial application field This invention consists of a box-shaped machine body, in which a sorting cylinder with many potholes formed on its inner circumferential surface is supported by a plurality of rollers and rotated. A pothole type sorting machine which is movably mounted horizontally and has a receiving gutter inserted through and horizontally mounted within the sorting cylinder, wherein the sorting cylinder is configured to be freely inserted and removed in the direction of the rotation axis of the sorting cylinder. This invention relates to a device that improves the efficiency of the sorting action of objects and facilitates the insertion of the sorting cylinder.

(b) Prior art As mentioned above, a sorting cylinder is supported by a plurality of rollers in a box-shaped machine body, horizontally mounted so as to be rotatable, and a receiving gutter is inserted into the sorting cylinder and horizontally mounted. A pothole type sorting machine in which the sorting barrel is configured to be freely inserted and removed in the direction of the rotating axis of the sorting barrel is disclosed as a conventional technique, for example, in Japanese Utility Model Application Publication No. 158483/1983. It's something like this.

However, the method disclosed in this publication does not take any measures to improve the efficiency of the sorting action by providing a member that promotes the sorting and separation action by scooping up the pot holes in the sorting barrel. Also, it does not incorporate technical features such as a guide member that makes it easy to insert and remove the sorting barrel from inside the machine.

Therefore, with the conventional configuration as described above, it is not possible to improve the efficiency of the sorting action within the sorting cylinder.
Moreover, it has the disadvantage that it is not easy to insert and remove the sorting barrel from inside the machine.

(c) Problems to be solved by the invention This invention solves the problem that with the conventional configuration as described above, the efficiency of the sorting action within the sorting cylinder cannot be improved, and when the sorting cylinder is inserted and removed from the machine body. However, since it has the disadvantage that the work is not easy, a sorting promoting member is installed inside the sorting barrel to improve efficiency and to make the work easier when inserting the sorting barrel into the body of the machine. The present invention is also proposed for the purpose of reinforcing the sorting promoting member.

(d) Means for solving the problem In order to accomplish the above-mentioned purpose, the present invention includes a sorting barrel with a number of potholes formed on its inner circumferential surface, which is supported by a plurality of rollers inside the machine. A pot-hole type sorting machine comprising a sorting cylinder that is horizontally mounted so as to be rotatable, and a receiving gutter is inserted into the sorting cylinder and horizontally mounted thereon, and the sorting cylinder can be freely inserted and removed in the direction of the rotational axis of the sorting cylinder. In the sorting cylinder, a sorting promoting member that can be brought close to the inner peripheral surface of the sorting cylinder is supported from the receiving gutter side, and the rotating axis on the sliding side of the sorting cylinder is known, and the sorting promoting member A guide member is disposed diagonally across the lower end of the guide member.

(e) Effect Since the present invention is constructed as described above,
For example, when a mixed rice of brown rice and paddy is fed into the sorting cylinder and sorted into brown rice and paddy, the sorting promoting member as shown in the embodiment is used to deflect the rice to the inner peripheral surface in the rotation direction of the sorting cylinder. The upper layer of the fluidized bed, which flows while exhibiting an upwelling state, has a high proportion of brown rice, and is made to flow back more than the fluidized bed, giving priority to the brown rice fitting into the pot holes, thereby improving the sorting efficiency. When inserting the sorting cylinder that has been extracted from the outside of the machine from its insertion/extraction side, the guide member slides the inner peripheral edge of the end of the sorting cylinder onto the beveled edge of this guide member, and guides the leading side of the sorting cylinder downward for sorting. The insertion is facilitated by reaching the lower side of the sorting promoting member which can be supported close to the inner circumferential surface of the barrel.

(f) Examples The present invention will be specifically explained below based on the drawings of examples. The pothole type sorter c shown in this example diagram is installed in a huller as shown in Figure 2 to sort the mixed rice of brown rice and paddy after de-air sorting, so the general outline of this huller is as follows: First of all, I would like to describe the following: A removing section A is installed in the front part above the wind sorting part B, and a pot-hole type sorter C according to the present invention is installed in the rear part, and it is integrated on the machine body 1 to remove the rice grains. The paddy that constitutes the machine and is put into the paddy tank 2 is slid down by a pair of unrollers 3 and is air sorted in a sorting air passage 4. The rice grains are discharged from the machine through the suction dust extractor 5, the rice cakes are taken out from the rice gruel trough 6, and the mixed rice of brown rice and paddy is taken out from the mixed rice take-out trough 7 extending into the front cross-transfer case a to the elevator D. Foreign matter such as pebbles and metal pieces mixed in the mixed rice is removed by being lifted up in the front chamber and flowing into the foreign matter removal case 8, and a supply gutter 9 continuous to one side of this foreign matter removal case 8 is removed. to go into. Inside the foreign matter removal case 8, as shown in FIG. 3, there is provided a sieve line 10 which is pivoted at one end and installed obliquely. As shown in the figure, the degree of inclination can be freely changed and adjusted. Reference numeral 11 denotes a foreign matter removal gutter which is continuous to the other side of the foreign matter removal case 8, and foreign matter mixed into the mixed rice is sieved through a sieve line 10.
0, fall into the foreign matter removal gutter 11, and are taken out of the machine. The aforementioned supply gutter 9
The mixed rice that has entered is sent to the rear side through the transfer gutter 14 through the sorting barrel 13, which has a number of pot holes 12 formed on its inner circumferential surface, and falls from the drop opening 15 onto the inner circumferential surface of the sorting barrel 13, where it is placed in a pot. Due to the scooping action of the hole 12, the brown rice is transferred to the receiving gutter 16.
After being separated and sent to the front side, it is led out to the rear side of the wind selection section B through the brown rice take-out gutter 17 and into the wind selection path 1.
At step 8, the waste rice is removed and lifted into the rear chamber of the elevator D from the brown rice take-out gutter 19 extending into the rear cross-transfer case b, and is taken out to a suitable location outside the machine. In addition, the paddy separated from the brown rice is lifted up by buckets 21 distributed evenly on the inner circumferential surface of the sorting barrel 13 on the front side and falls upward, and this falling paddy is caught by the return gutter 21 and transferred to the paddy tank 2. It is reduced and supplied to the derolling unit 3 again. Also 22 is Fusenro 18
A waste rice removal gutter is installed horizontally at the end of the mixed rice removal gutter 7, and extends into the front transverse case a at a different level from the mixed rice removal gutter 7.

Next, details of the pothole type sorter c of the present invention will be described.

The body of this pothole type sorter c is formed into a box shape from a thin iron plate, and the receiving gutter 16 and the transfer gutter 14 are fixed to the body at the front side and supported in a cantilevered manner, and are installed horizontally in the front and rear direction. The rear side, which is the end, is integrally connected to a support plate 23 formed by cutting out the upper and lower parts of a circular plate.
The shaft ends of the screw conveyors 24 and 25 installed in the receiving gutter 16 and the transfer gutter 14 are inserted through the support plate 23 and supported, and the end of the fulcrum shaft 27 of the gate valve 26 whose posture can be changed freely is also supported. It is supported by a plate body 23.

The rear side of the machine has an opening 28 large enough to allow the sorting barrel 13 to be freely inserted and removed from the machine, and a shielding plate 29 is fitted between this opening 28 and the support plate 23, and is secured by several knob screws 30. The support plate body 23 is firmly supported through the shielding plate 29 by being tightened and fixed to the rear side of the fuselage and the support plate body 23.

In addition, the rear side of the sorting cylinder 13 through which the mixed rice is supplied from the dropping port 15 has an overflow prevention wall 31 formed by bending the end periphery, and the inside peripheral edge of this overflow prevention wall 31 is made of rubber. The elastic annular body 32 is fitted, and the elastic annular body 3 is attached to the inner surface of the shielding plate 29.
A cylindrical flange 33 whose outer peripheral surface is joined to 2 is attached.

Note that 34 and 35 are transparent plates and opaque plates that close the upper and lower notches of the support plate body 23;
A cover 6 covers the shaft ends of the screw conveyors 24 and 25 and the end of the fulcrum shaft 27 of the gate valve 26.

The sorting cylinder 13 has a pair of shaft wheels 3 on its front and rear sides.
It is supported by a plurality of wheels 7, 37 and 38, 38 and horizontally mounted so as to be rotatable.
A power transmission shaft 42, which receives power from a drive shaft 41 taken out from the gear box of the removal section A, is connected to one of the wheel shafts 39 and 40 to which the wheels 8 and 38 are attached, by a shaft coupling 43. Pothole type sorter C
The side is being transmitted.

In addition, inside the sorting cylinder 13, there is a sensing valve 44 for knowing the amount of mixed rice at the rear side and front side where the mixed rice is supplied, and a fluidized bed of mixed rice is partitioned into upper and lower parts, and the upper layer is removed by the rotation of the sorting cylinder 13. A sorting promoting member 45 is provided in the direction opposite to the moving direction A to cause the fluidized bed to flow back.

This sensing valve 44 is caused by the thickness and thinness of the mixed rice layer flowing while being biased towards the rotating direction A side of the sorting cylinder 13 and exhibiting a raised state.
This support shaft 46 is attached to the inner circumferential surface of the
and a fulcrum shaft 27 of the gate valve 26 are interlocked and connected via a link mechanism on the front side, and a weight is provided at the rear end of the fulcrum shaft 27 to bias the sensing valve 44 toward the inner circumferential surface of the sorting barrel 13. 47 is attached, and this weight 47 is housed within the cover 36.

In addition, swash plates 48 are arranged at equal intervals on the operating surface 44a of the sensing valve 44, which corresponds to the inner circumferential surface of the sorting cylinder 13, and serve to send the mixed rice forward.

Therefore, when the amount of mixed rice supplied into the sorting cylinder 13 increases or decreases, the sensing valve 44 follows the thickness of the fluidized bed and moves away from or closer to the inner peripheral surface of the sorting cylinder 13 to partition the rice. Change the posture of the valve 26 and
The amount of brown rice received into the fluidized bed 6 is increased or decreased, and the mixed rice flowing back through the upper layer of the fluidized bed is laterally fed to the front side using the diagonal installation 48.

16a and 16b are the main body and side plates constituting the receiving gutter 16, and the side plate 16b is connected to the main body 16a and is configured to be rotatable in the rotational direction A of the sorting cylinder 13 using the lower end as a fulcrum, and is located at the upper edge of the main body 16a. As shown in FIGS. 5 and 6, the upper end is maintained close to the inner circumferential surface of the sorting cylinder 13.

The sorting promoting member 45 is fixed to the lower ends of several support plates 49 which are provided to protrude downward from the back surface of the transfer gutter 14, so as to be close to the inner peripheral surface of the sorting cylinder 13 and supported in an inclined manner.

Therefore, this sorting promotion plate 45 allows the upper layer of the fluidized bed with a high proportion of brown rice to flow back than the fluidized bed so as to slide on the upper surface 45a, giving priority to the brown rice fitting into the pot hole 12, thereby increasing the sorting efficiency. It makes things better.

Furthermore, 50 is a guide member whose upper end is fixed to the back surface of the transfer gutter 14 and is provided diagonally downward on the front side, and whose lower end is connected to the lower end 45b of the sorting promotion member 45, This sorting promotion member 45 is strongly reinforced.

Further, a guide rail 5 is provided on the lower side of the sorting cylinder 13.
1 and 52 are horizontally installed in parallel with the sorting cylinder 13 in the longitudinal direction, that is, in the direction of the rotational axis of the sorting cylinder 13, with the front and rear ends fixed to the body respectively,
When horizontally installing the sorting cylinder 13, the front and rear wheels 3
In the rotatable state supported by the sorting cylinders 7 and 38, there is a slight gap between the outer peripheral edges of the flanges 53 and 54 formed at the front and rear parts of the sorting cylinder 13 and the guide rails 51 and 52.

Since the pot-hole type sorter c is constructed as described above, when removing the sorting barrel 13 from the machine, first remove the cover 36 from the support plate 23, remove the transparent plate 34 and the opaque plate 35, and then remove the knob. When the screw 30 is loosened and the shielding plate 29 is removed, the cylindrical flange 33
The rear part of the fuselage is also taken out and a large opening 28 is made at the rear of the fuselage, as shown in FIG.

At this time, the receiving gutter 16, the transfer gutter 14, the gate valve 26, etc. are supported in a cantilevered manner with the free end side, which is the rear side, integrated with the support plate body 23.

Therefore, by the force of the weight 47, the sorting cylinder 1
3, and the side plate 16b of the receiving gutter 16, whose upper end is kept close to the inner circumferential surface of the sorting barrel 13, should be folded down as shown by the arrow B. The gate valve 26 is tilted by the weight of the side plate 16b of the cigarette against the biasing force of the weight 47, and in conjunction with this tilting, the sensing valve 44 moves upward and becomes the state shown in FIG. It will move away from the surface.

In this state, insert your hand through the opening 28 and select the sorting cylinder 1.
When the rear part 3 is slightly lifted and pulled out, the flange 53 on the front side can be taken out while sliding on the upper surfaces of the guide rails 51 and 52, resulting in the state shown in FIG.

Next, when inserting the removed sorting cylinder 13 back into its original state, the sorting cylinder 13 is inserted through the opening 28 and the flange 53 is slid on the guide rails 51, 52. It will now be inserted as shown in the imaginary line. In this case, the inner peripheral edge of the front end of the sorting barrel 13 will come into contact with the oblique edge of the guide member 50, but if it is inserted further in this state, the inner peripheral edge that contacted will slide against the guide member 50, causing the preceding front part to move downward. Guide to the sorting cylinder 13
The guide rails 51, 5
It can be inserted along side 2.

Incidentally, the sorting promoting member 45 shown in this embodiment allows the upper layer of the fluidized bed formed on the inner peripheral surface of the sorting cylinder 13, which has a higher proportion of brown rice, to flow back than the fluidized bed, so that the brown rice can flow into the pot hole 12. Although it plays the role of promoting sorting by prioritizing fitting, the term "sorting promoting member" as used in the present invention refers to a member having a broad meaning and is not limited to such a member.

(g) Effects of the invention As detailed above, the invention consists of a sorting cylinder with a number of potholes formed on its inner circumferential surface, which is supported by a plurality of rollers in the body of the machine so as to be rotatable laterally. In a pothole type sorting machine which is constructed by horizontally suspending the sorting cylinder and inserting a receiving gutter into the sorting cylinder, the sorting cylinder is configured to be freely inserted and removed in the direction of the rotation axis of the sorting cylinder. In the sorting cylinder, a sorting promoting member that approaches the inner circumferential surface of the sorting cylinder is supported from the receiving gutter side, and the rotating axis on the sliding side of the sorting cylinder is known, and the sorting promoting member is guided across the lower end of the sorting promoting member. Since the members are arranged diagonally, it is possible to improve the sorting efficiency by means of the sorting promotion member provided in the sorting barrel, and the sorting barrel can be removed and removed from the inside of the machine. When inserting the extracted sorting cylinder into the machine body, the guide member allows easy insertion despite the presence of a sorting promoting member that is close to the inner circumferential surface of the sorting cylinder. Moreover, the guide member has the advantage that it can also serve as strong reinforcement for the sorting promotion member.
