The main sorting mechanism C1 is housed in a frame 2 installed above the housing 1, the conveyor mechanism D supplies the sorting material grains to the main sorting mechanism C, the winnowing mechanism E with a supply hopper 3, etc. The operating parts of each mechanism are connected to a drive source by a required drive mechanism to perform a predetermined operation, and the general arrangement is as shown in FIG. 3.

In other words, when the shutter 4 of the supply hopper 30 is opened, the sorting material grains input into the supply hopper 3 are caused to flow down the passage in the winnowing mechanism E in appropriate amounts by the feed roll 5, and are subjected to pre-processing and sorting in the winnowing mechanism E. After being received, the particles of material to be sorted are conveyed to the upper end of the conveyor mechanism from the input hopper 6 to the sorting surface of the endless sorting belt 7.7 of the main sorting mechanism C. 7a.

7a, and the endless sorting belt 7.7 separates only the sorted grains by its rotation and takes them out from the take-out lowers b, 7b, and sends other grains etc. to the auxiliary sorting mechanism A. The sorted grains are introduced into the sorting net barrel 9 of the grain sorting mechanism B from the take-out port through the guide passage 8, and the grains are sorted by size and collected by collection tools 10ay and 10bt, respectively.
10c, other grains, etc. are sorted by the sorting belt 11 of the auxiliary sorting mechanism A, waste grains, etc. are collected at the second port 12, and the others are fed again to the conveyor mechanism from the flow path 13. It is configured to do so.

In addition, 14 is the inclination adjustment mechanism of the main sorting mechanism C, 15 is the inclination adjustment mechanism of the auxiliary sorting mechanism A, 16 is the angle adjustment tool of the grain sorting mechanism B, 17 is the distribution valve, 18 is the overflow reduction cylinder,
Number 19 is a fan of Karagi.

The main sorting mechanism C winds and hangs endless sorting belts 7.7 in two stages, upper and lower, inside the frame-like body 2, and each endless sorting belt 7.
As shown in a schematic perspective view in FIG. 4, 7 is a sorting operation surface 7a, ? The belt is tilted so that the front side of the rotation direction A in the belt rotation direction A is on the upper side, and the belt is also tilted in the width direction (direction perpendicular to the direction A). A concavo-convex strip facing in the width direction is formed on the wall portion 2a of the frame-like body 2 at the corner portion corresponding to the upper portion of the slope of the sorting belt 7.7 in the width direction and the lower portion of the slope in the rotation direction. The supply ports 20 and 20 are opened respectively, and each supply port is connected to the distribution path of the input hopper 6 described above, and the discharge side is opened onto the sorting surface 73° 7a of the endless sorting belt, and the supply ports are connected to each other. 20.20
Supplying the sorting material rice grains onto the sorting action surfaces 7a, 7a,
These material grains are separated into regular grains and other grains by rotating the endless sorting belt in the A direction. The structure is such that the grains, etc. are delivered to the auxiliary sorting mechanism A from the communication section at the upper part of the slope in the direction of rotation of the belt.

At the joint portion of the sorting material rice grains between the supply port 20.20 and the endless sorting belt 7.7, there is a sorting action surface 7a from the lower side of the supply port 20.
A supply guide plate F having an upwardly extending guide tongue portion 21 and a vertical rising guidance guide portion 22 integrally provided with this tongue portion is attached to prevent stagnation or stagnation of sorting material paddy grains. This is to avoid creating congestion.

A rectifying plate G is provided on the sorting surface 7a outside the supply port 20 for temporarily storing the sorting material rice grains and then diffusing and supplying them to the sorting surface 7a. The opening 20 is extended from the upper wall part 2a of the endless sorting belt rotating direction, and the end side thereof is extended to the lower part of the belt width direction inclination, gradually forming the endless sorting belt lower part of the endless sorting belt rotating direction. The mounting body 23 is provided so as to be inclined toward the side, and is equipped with a comb-like body 24 made of an elastic material and hanging down toward the sorting surface 7a.

A rack plate 25 is installed above the sorting surface 7a of the endless sorting belt 7 so as to be close enough not to interfere with the rotation of the belt 7, and this rack plate 25 is located near the supply port 20. From the part located at The free end of the baffle plate G is brought close to or in contact with an arbitrary cylindrical part of the rack part so that the material particles flowing down to the side are diffused to the upper side of the inclination in the belt rotation direction.

Note that an appropriate upper cylindrical portion of the space located on the sorting surface 7a near the supply port 20 and surrounded by the rectifying plate G and the rack body 25 is an integral cover 29 made of transparent soft elastic material attached to the frame-shaped body 2.
The cover 29 can be rolled up to open the space.

Thus, the rice grains to be sorted from the conveyor mechanism to the input hopper 6 are divided into two in a predetermined manner, and are guided through the distribution path to each supply port 20, 20 due to the presence of the supply guide plate F. , the working surface 7a of the endless sorting belt 7.7,
7a.

Sorting action surface 7a, ? The sorting material paddy grains flowing out onto the surface a are prevented from directly flowing down along the widthwise slope of the endless sorting belt 7 by the rectifying plate G installed obliquely on the outside of the supply port 20, and are not stored once. From the interval between the comb teeth 24, from the rotational force side to the direction perpendicular to the inclination direction of the adult products 24 (direction toward FIG. 6), that is, the lower inclination side in the width direction of the endless sorting belt 7. The endless sorting belt 7.
While being diffused in this way and being transported by the endless sorting belt 7.7, the sorted grains of the sorting material are spread along the uneven stripes in the width direction of the belt. The extraction lower b is caused to flow downward in the direction of inclination.
The grains, which are relatively light in weight and difficult to roll compared to the sorted grains, are carried to the upper end of the tilt in the rotating direction and are supplied to the auxiliary sorting mechanism A for good separation. It is.

As explained above, the present invention does not allow the material grains supplied onto the sorting surface of the endless sorting belt to flow down directly along the inclination in the width direction of the belt, but instead stores them while moving them onto the sorting surface of the endless sorting belt. The supply is diffused and supplied from the rotation direction side to the horizontally inclined lower side.

Since the baffle plate G is installed, the material grains are unraveled and supplied onto the sorting surface, allowing rapid downstream separation of the grains and layered transport of crushed grains in the direction of belt rotation. is carried out reliably, and the free end of the rectifying plate G is extended toward the lower side of the inclination in the width direction of the endless sorting belt, and the lower side of the inclination in the belt rotation direction is gradually extended toward the alligator, resulting in a comb-teeth state. 24, the material grains are not stagnate and are reliably diffused over a wide range, further promoting the above-mentioned effect.
