Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a sorting body which is provided with a mixture containing two or more kinds of granules from the upstream side in the feeding direction and is placed on the sorting surface so that the sorting body can swing. A plurality of protrusions for locking and moving the granular material to be located in the lowermost layer are formed in a distributed manner, and the specific granular material is fed in the feeding direction while transferring the mixture in the feeding direction with the swinging operation of the sorting body. The present invention relates to a sorting device configured to sort and move in a sorting direction different from the above, sort the mixture, and feed the mixture from the lower side in the feeding direction.

[0002]

2. Description of the Related Art Conventionally, in the above sorting apparatus, the sorting body having a plurality of projections dispersedly formed on the sorting surface is suspended and supported while being inclined so that the sorting surface becomes lower toward the lower side in the feeding direction. Together with a movement regulation mechanism that regulates the reciprocating movement of the sorting section in the feed direction and the reciprocating movement in the sorting direction to swing the sorting section, and the mixture (for example, grain after hulling). ) In the lowermost layer (when the mixture is grain after hulling, brown rice will be in the lowermost layer), and the granular material is sorted and moved in the sorting direction in the lowermost layer. It has been previously proposed that the projection formed in at least a part of the separated area is configured to lock and move the granular body in the feeding direction (for example, Japanese Patent Application No. 3-145732). No.).

[0003]

The above conventional structure is designed to prevent the mixture from staying on the sorting surface and to smoothly transfer the granular material in the feeding direction.
In the case of the above structure, since the shape of the protrusions is formed in correspondence with the shape of the granular body, it exhibits an effective feeding action for a specific granular body, but the mixture has, for example, small stones or There is a case where a small-sized object to be sorted such as crushed crushed rice is mixed, and if such a small-sized object to be sorted stays in the state of being inserted between the protrusions, the original sorting performance of the mixture is deteriorated. There was a possibility that there was still room for improvement. The present invention aims to eliminate the above-mentioned problems.

[0004]

A characteristic configuration of the present invention is that, in the sorting apparatus described at the beginning, a part of a region in which the specific granular material is sorted and moved in the sorting direction in the lowermost layer and has been separated. In addition, a porous portion is formed to allow the objects to be sorted having a diameter smaller than the set value to leak downward.

[0005]

On the sorting body, in the region where the mixture may remain after the specific granular body is sorted and moved in the sorting direction in the lowermost layer to be separated, it is formed in a part of the region. Through the porous part, the unnecessary object to be sorted, which has a diameter smaller than the set value and is different from the object to be sorted, leaks to the lower side. The above-mentioned unnecessary objects to be sorted do not accumulate in the area that tends to stay, and the sorting and movement of the granular bodies that are the original sorting targets are smoothly performed.

[0006]

Therefore, by providing the porous portion at a reasonable position, it is possible to prevent the selective transfer of the mixture containing two or more kinds of granular materials in other regions from being hindered, while preventing the selective transfer on the selective body. It is possible to prevent unnecessary substances to be sorted with a small diameter different from the original sorting target from accumulating, and to smoothly sort and transfer the mixture that is the sorting target, thus improving sorting performance. It was

Embodiments will be described below with reference to the drawings. As shown in FIGS. 3 and 4, the brown rice sorting device as one embodiment of the device of the present invention is a grain (hull) after the hulling process is performed in the hulling part 23a and the chaff is removed by the wind selecting part 23b. Is a mixture of unpolished rice and unpolished brown rice, which will be referred to as a mixture hereinafter) at the sorting surface 1A via the supply unit A and from the start end to the end in the feeding direction X (vertical direction in the plane of FIG. 3). While being transported, it is separated in a sorting direction Y orthogonal to the feeding direction X (specifically, as will be described later in detail, it separates brown rice, mixed rice, and paddy), and a plurality of upper and lower stages (5 in this embodiment). Dan)
The main body includes the sorting body 1, the collecting unit B that separates and collects the sorted grains discharged from the terminal ends of the plurality of stages of sorting bodies 1, and the base frame F that supports these. The sorting apparatus also includes a movement regulating mechanism N that causes the swinging movement of the sorting body 1 while regulating the reciprocating range of the sorting body 1 in the feeding direction X and the sorting direction Y. Then, the mixture is separated based on the rocking operation.

The supply section A comprises a supply hopper 3 which is fixedly arranged, a receiving hopper 4 and a guide body 5 which are supported by the sorting body 1, and a cylindrical body 6 which connects the hoppers 3 and 4 to each other. At the bottom of the guide body 5, as shown in FIG.
A plurality of guide passages 5a are formed to divide and guide the mixture in the receiving hopper 3 to the respective sorting bodies 1. The entrance of each guide passage 5a faces the bottom of the receiving hopper 4, and
Are provided so as to be lined up along the sorting direction Y, and their outlets are connected to the supply ports 8 formed on the starting end side walls 7a of the sorting bodies 1. Each of the cylindrical body 6, the receiving hopper 4, and the guide body 5 is attached to the starting end portion of the plurality of stages of sorting bodies 1 so as to move integrally with each sorting body 1. still,
The respective sorting bodies 1 are connected and integrated with each other at the angle 7A and are supported by the movable frame 11, so that they can be integrally moved relative to the base frame F.

As shown in FIG. 6, inside the supply hopper 3, an upper limit sensor S1 for detecting that the stored amount of the mixture is almost full, and a lower limit sensor for detecting that the stored amount is below a set value. S3 and an intermediate sensor S2 located between them are provided, and the supply amount to the hulling section 23 is changed and adjusted based on the detection results of these sensors. That is, the shutter 25 that can be switched between the state in which the supply port from the supply tank 24 to the hull portion 23 is opened and the state in which the supply port is blocked, and the electric motor 26.
And a supply amount adjusting plate 27 that can be swung by the control unit to change and adjust the supply amount, and these are driven and controlled by a control device. That is, the control device 28
When the lower limit sensor S3 is in the detection state, the later-described electric motor 26 is driven to start the swing sorting operation by the sorting body 1, and when the lower limit sensor S3 is in the non-detection state and the stored amount becomes small, the sorting body 1 swings. Stop the dynamic sorting operation. Further, when the supply amount from the hulling section 23 increases and the upper limit sensor S1 is in the detection state, the shutter 25 is closed and the supply is stopped. Then, when the intermediate sensor S2 is in the detection state, the opening amount of the supply amount adjusting plate 27 is maximized, and when the intermediate sensor S2 is in the non-detection state, the opening amount of the supply amount adjusting plate 27 is minimized. To do.

As shown in FIGS. 1 and 2, the periphery of each of the sorting bodies 1 is surrounded by a side wall 7, and the sorting surface 1A of the sorting body 1 is swung by the swinging of the sorting body 1 from the mixture. A plurality of protrusions 10A and 10B for locking and moving the brown rice to be located in the lower layer are formed in a dispersed manner. The plurality of protrusions 10A, 10B are two types of protrusions 10A,
10B, that is, the lowermost layer of brown rice is locked and moved in one direction Y2 of the sorting direction Y (Y2 at the position where the supply port 8 is formed), and the lowermost layer of the protrusion 10B. A second type of protrusion 10A configured to lock and move brown rice to the lower side X1 in the feeding direction X is divided into two parts. It should be noted that the two types of protrusions 10A and 10B have the same structure as shown in FIG.
As shown in FIG. 3, a gentle slope 10a gradually adjoining the selection surface 1A is formed on one side thereof, and a locking portion 10b capable of locking brown rice is formed on the other side thereof. Incidentally, FIG. 2 shows the second-type protrusion 10A.
The locking portion 10b of the protrusion 10A is formed on the lower side X1, and the locking portion 10b of the first type protrusion 10B is formed.

The boundary line between the formation positions of the two types of protrusions 10A and 10B is the second line in at least a part of the region where the brown rice has been sorted and moved in the sorting direction Y in the lowermost layer. It is set so that a type of protrusion 10A is formed. Specifically, a straight line parallel to the feeding direction X (in FIG. 1) at a position close to the boundary between the brown rice region G and the mixed rice region K (see the alternate long and short dash line in FIG. 1) which will be described in detail later. (See the chain double-dashed line). The projections 10A and 10B are easily formed by subjecting the sorting body 1 made of a metal plate material to plastic working such as press working, and the boundary line is formed in the feeding direction X. The setting of a straight line parallel to is useful for improving workability in performing plastic working such as the press working.

The second type projection 10A is provided in a region including the portion where the staying portion is generated, and even if the staying is about to occur on the sorting surface, the stay 10A It becomes possible to avoid the occurrence of the retention by severing by the granular body locking movement force based on it.

The swinging mechanism of the sorting body 1 will be further described. As shown in FIG. 4, the sorting body 1 has a feeding direction X.
The lower side X1 has a slope (flow angle: θ) in which the selection surface 1A is located downward, and as shown in FIG. 3, the side Y1 opposite to the formation position of the supply port 8 in the selection direction Y is The selection surface 1A has a gradient (selection angle: α) located below, and only the brown rice in the mixture is locked and moved by the locking portion 10b of the second type projection 10A to select in the selection direction Y. To the formation position side Y2 of the supply port 8 of
Thereby, the brown rice is separated and moved in the sorting direction Y from the mixture.

As shown in FIGS. 4 and 5, the movement regulating mechanism N suspends the sorting body 1 in an inclined posture with respect to the base frame F while allowing the sorting body 1 to move in the feeding direction X and the sorting direction Y.

The belt 1 is attached to the first shaft 14.
An electric motor 19 as a drive unit is transmission-coupled via 8 as shown in FIG. 4, and the crank 15 is driven by the drive of the electric motor 19, whereby the end of the sorting body 1 on the upper side X2. Is rotated around the first shaft 14 and the end portion (lower side portion 1a) of the lower side X1 of the sorting unit 2 is swung around the second shaft 16, whereby the sorting body 1 of the sorting body 1 is rotated. Grain supply position I on the starting side
The mixture supplied from (formation position of the supply port 8) is sorted into three areas, an area G of brown rice, an area K in which paddy and brown rice are mixed (so-called mixed rice area) K, and an area M of paddy. (The boundary lines between them are indicated by a chain line in FIG. 1).

Then, a part of a region on the sorting body where the second type projection 10A is formed,
In the vicinity of the swing arm 17, a porous portion Q for letting down the sorted objects having a diameter smaller than a set value downward is formed. The porous portion Q is formed in a mesh shape, and is configured to leak down to-be-sorted objects such as broken rice and small stones crushed in the hulling process in the hulling portion in the brown rice region G. . Further, below the porous portion Q, there is provided a broken rice recovery unit 29 for recovering the leaked material to be sorted.

The collecting section B is provided with a collecting hopper 20 connected to the terminal end of the sorting body 1, and inside the collecting hopper 20, brown rice and mixed rice are mixed as shown in FIG. A first partition plate 21 for separating and a second partition plate 22 for separating mixed rice and paddy are provided.
