Ring-shaped frames 40.41 are integrally formed on both ends of the grain selection net 16, and the frames 40.41 are attached to the drums 38.39.
41 and one drum 39 via the bolt 43.
The frame 41 is removably attached to the frame 41, and the outlet 8a of the hopper 8 fitted into the opening 6a of the front cover 6 is made to face inside the front drum 38, and the intervals between the drums 38, 39 and the small particle outlet 3 are adjusted. The rear drum 39 is formed to have approximately the same length, and the end of the rear drum 39 faces the large grain outlet 15.

Furthermore, the other ends of the support shafts 44 and 44, one end of which is fixed to both ends of the bearing bracket 28, protrude outward from the front cover 6, and a fixed bracket is attached to the ends of the support shafts 44.45.45

The stand 53 is formed so that it can be expanded and contracted by moving it forward and backward.

By the way, a partition plate 56 as shown in FIG. 5 is provided behind the rear falling guide 5 on the inner surface of the lower part of the body cover 1 mentioned above.

This partition plate 56 extends to a large length in the direction of rotation of the grain sorting net 16, and the small particles that are sorted by the grain sorting net 16 and fall downward from the flow guide 5 are collected from the machine body. It is provided so as to prevent the large particles from flowing into the outlet 15 due to the slope.

Furthermore, as is clear from FIGS. 3 and 4, the connection structure between the drive shaft 31 and the motor output shaft 34 described above is such that the shaft end of the drive shaft 31 is formed into a bifurcated shaft having an engagement groove 57. At the same time, a fitting hole 35 of the connector 35 into which the drive shaft 31 is fitted is provided.
A pin 58 is provided through the fitting hole 35a, and when the drive shaft 31 is inserted into the fitting hole 35a, the pin 58 is locked in the engagement groove 57, thereby interlocking the two. It is something that exists.

Next, the specific structure of the grain sorting net 16 will be explained. The frames 40 and 41 mentioned above are fixed to both sides of the iron net 16 separated by an appropriate interval.

The frames 40 and 41 are each made up of two ring-shaped frame pieces 40a.

40 b , 41 a , and 41 b are joined from the inside and outside by sandwiching the net 16 inside, and these frames 40
．． As shown in FIGS. 6 and 7, three reinforcing plates 59 are stretched between the holes 41 at equal intervals.

These frames 40, 41 are fitted and supported by the aforementioned front and rear drums 38, 39, respectively, and three bolts 43 are inserted at equal intervals in the fitting portions of the rear drum 39. A hook groove 60 corresponding to the bolt 43 is screwed onto the end of the rear frame 41 (see Fig. 8).
are bored in three places, and the bolts 4 are inserted into the grooves 60.
By engaging and screwing 3, the rear frame 41 is fixed to the rear drum 39, and the entire particle selection net 16 is fixed.

As is clear from FIG. 8, the hooked groove 60 has a groove 60a on the back side, which serves as a locking portion, formed in the opposite direction to the rotating direction of the grain selection net 16.

The present invention is constructed as described above, and when unsorted grains such as sorted soybeans, from which dust and waste particles have been removed in advance to extract only fine grains (sorted grains), are put into the hopper 8, the motor 17 rotates the grains. A front drum 38 is installed inside the grain selection screen 16 that is being driven.
The unselected grains fall from the outlet 8a of the hopper 8 through the inner surface, and fall along the inclination of the grain sorting net 16 in the axial direction.

Then, the relatively small particles fall through the mesh of the particle sorting net 16 to the small particle outlet 3, and the small particles are taken out into the container 20 below this outlet 3, and the relatively large particles are removed from the particle sorting screen. 1
6 inside to this inclined lower end side and fall through the rear drum 39 to the large particle outlet 15, and the container 2 below this outlet 15.
The large grains are taken out in step 1, and the grain sorter is used to accurately separate the unsorted grains fed into the hopper 8 into small grains and large grains.

Further, the front drum 38, which serves as a joint between the hopper 8 and the grain sorting net 16, prevents unselected grains falling from the hopper 8 from accumulating or scattering below the outlet 8a. The grains are smoothly transferred to the grain sorting net 16 and flowed down along the inclination of the grain sorting net 16, and the large grains that are sorted during the flow and reach the rear part of the grain sorting net 16 are quickly transported by the rear drum 39 connected to the rear of the grain sorting net 16. The large grains are discharged to the large grain outlet 15.

Next, in the case where the particle sorting net 16 becomes clogged or damaged and needs to be replaced, the removal order will be explained with reference to FIG. The machine is set upright, the bolts 7 are removed, the front cover 6 is removed from the machine body cover 1, and the bearing sleeve 30, which is one of the bearings of the drive shaft 31, is removed.

Then, the grain selection screen 16 is removed from the machine cover 1 together with the drive shaft 31 and drums 38 and 39.

After that, loosen the bolts 43 that fix the rear frame 41 and the rear drum 39, and
The frame 39 that is engaged with the drums 38 and 3 is slightly rotated in the direction of rotation of the grain sorting net 16, and pulled out to release the engagement between the bolt 43 and the hook groove 60 of the frame 41, and the frame 39 is removed from the drums 38 and 39. 40.41 That is, the grain selection net 16 is removed, and when a new grain selection net 16 is installed, the operation is reversed to that described above.

Further, the hopper 8 is removed from the front cover 6 by removing the bolts 9.

In the above embodiment, the rear drum 39 and the rear frame 41 are fixed to each other by engaging the bolts 43 of the drum 39 with the hook grooves 60 of the frame 41 and further tightening the bolts 43. As shown in FIG. 8, the outer protruding portion of the drum 39 of the bolt 43 is formed into a straight portion 43H without a thread, and the hook groove 60 of the frame 41 is simply engaged with the straight portion 43A as described above in FIG. 43 may be made unnecessary.

In this case, the groove portion 60a that engages the bolt 43 on the back side of the hook groove 60 is on the opposite side to the rotation direction of the grain sorting net 16, and due to the inclination of the grain sorting net 16, there is no rear part of the iron net 16. Because the thrust force is acting on the drum 39 side, the drum 38
．． 39, there is no concern that the frame 40.41 will come off or shift its position, and in this configuration, there is no need to take out the drive shaft 31 and the drum 38.39 to the outside of the fuselage cover 1, and they are integrally formed with the frame 40.41. The grain sorting net 16 can be removed by simply taking out the grain sorting net 16.
There is no way that the replacement work in step 6 can be extremely efficient.
The aforementioned connection structure between the motor output shaft 34 and the drive shaft 31 also has the effect of simplifying the structure without requiring a separation structure.

Furthermore, although the bolts 43 are installed on the rear drum 39, they may of course be installed on the front drum 38 and the same effect can be obtained.

Further, the bearing tube 30 provided on the bearing bracket 28 needs to be longer than the width of the fitting part 6a of the front cover 6 with the fuselage cover 1, and the front cover 6 is not attached to the fuselage cover 1 before. A drive shaft 31 is supported by the bearing sleeve 30 so that the drive shaft 31 can be centered accurately.

As is clear from the above examples, in the present invention, unsorted grains are put into one side of the cylindrical grain sorting net 16 via the hopper 8, and relatively small particles are allowed to fall from the middle of the grain sorting net 16. In addition, in the structure in which relatively large grains are taken out from the other side of the grain sorting net 16, a ring frame 40.41 is fixed to both ends of the grain sorting net 16, and a drive shaft 31 to which the grain sorting net 16 is attached is attached. A pair of drums 3 separated by an appropriate distance
8.39 is pivotally supported, each of the ring-shaped frames 40.41 is fitted into the drums 38.39, and at least one of the ring-shaped frames 41 and the drum 39 are removably fixed. With a simple structure, the particle selection screen can be replaced easily and quickly, and the particle selection accuracy and work efficiency can be improved, which is a remarkable effect.
