The upper cylinder 23 includes a coupling structure with a motor 70 for use.

The grain lifting spiral body 30 is provided with a spiral blade 32 on the outer periphery of a spiral tube 31, and the lower end thereof is connected to a spiral body driving motor 80 as shown in FIG. Incidentally, the grain lifting spiral body 30 and the spiral body driving motor 80 are connected to each other by a well-known means such as a spline so that they can be freely fitted in the axial direction.

The outer shell 40 is erected on a base 41 as shown in FIG. 2 or 3, and is divided into a base portion 42 and an upper body portion 43.

In this embodiment, the upper body part 43 is divided into two parts, and the rear half is used as a door 46, which can be opened using a hinge as shown in FIG.

The door portion 46 is provided with a grain supply port 44 for supplying grains, and communicates with a grain receiving tube 47 inside the outer shell 40 as shown in FIG.

Further, a waste grain discharge port 45 is provided for discharging waste grains that have passed through the mesh of the sorting net 20 to the outside.

Furthermore, a handle 48 for opening and closing the door portion 46
is provided.

On the other hand, the outer periphery of the upper interior of the shell body 40 is provided with a funnel-shaped scraping chamber 49 that collects good grains and sends the grains to the tank 60.

Note that the particle receiving tube 47, the funnel-shaped scraping chamber 49, and the like are divided into parts that can be separated when the door is opened, along with the outer shell ceiling plate 50 and the like.

The sorting net 20 and the net driving motor 70 are constructed as follows.

First, as shown in FIG. 5, the net drive motor 70 consists of a motor body 71, a drive shaft 72, and a motor removal lever 73. A pyramidal portion 72a is provided so as to be easily detachable from the net body 20.

Further, a plurality of locking claws 71a that lock onto the outer shell ceiling plate 50 are provided on the lower end surface of the motor body 71 in order to support the counter torque applied to the net drive motor 70.

On the other hand, on the upper cylinder 23 of the sorting net 20, as shown in FIG.
A torque receiving portion 24 having a square hole 24a that engages with a pyramidal portion 72a is fixedly provided.

In this embodiment, the rotation speed of the spiral body driving motor 80 is made variable by controlling the input frequency, and the net body driving motor 70 is kept rotating at a normal constant speed. The rotation speed of the motor 70 can also be changed in the same way.

Next, the action will be explained.

As shown in FIG. 2 or 3, in order to take out the sorting net 20, fried grain spiral 30, etc. from the usable state, first the net driving motor 70 drives the upper sorting net 20. When the tip of the motor removal lever 73 is pushed down, the
As shown in the figure, the motor main body 71 is slightly lifted upward by the lever action, and the pyramid part 72a
The lock between the torque receiving portion 24 and the square hole 24a is released.

Thereafter, when the door 46 of the outer shell 40 is opened, the sorting net 20 and the like inside can be seen from the outside, as shown in FIG.

In this state, the guide peripheral edge 2 of the sorting net 20
If you insert your fingertip into the lower end of 1 and lift it up a little, you can see the internal grain frying spiral 30.If you hook your fingertip onto the spiral blade 32 and lift it up a little, it will disconnect from the spiral drive motor 80, and the sorting net will be removed. The body 20 and the grain frying spiral body 30 can be taken out of the machine laterally as they are.

To reconfigure, contrary to the above, the sorting net 20
The grain-lifting spiral 30 is fitted and inserted in the stacked state, and the grain-lifting spiral 30 is brought in from the side, and the grain-lifting spiral 30 is fitted onto the shaft of the spiral-driving motor 80. and door part 4
6, the net drive motor 70 is gently lowered, and the pyramidal part 72a is fitted into the square hole 24a of the torque receiving part 24 of the sorting net 20, completing the assembly.

Next, a second embodiment in which the torque transmission structure from the mesh driving motor 70 to the sorting mesh 20 is different will be described with reference to FIGS. 7 and 8. Note that the same reference numerals as in the first embodiment are given to the same parts, and redundant explanation will be omitted.

In this embodiment, the mesh drive motor 70 has a torque transmission member 74 in addition to the motor body 71 side, and is tightly fitted to the drive shaft 72 through a connecting hole 74a. A claw 74b that engages with the torque receiving portion 24 of the sorting net 20 and transmits torque is provided on the lower surface.

In addition, in the first and second embodiments, the outer shell 40 was divided into the rear half of the vertical grain sorter 10, but the part that is divided to become the door part 46 is the front half of the upper body part 43. Of course, it is also possible to do so.

Moreover, instead of dividing into two, it is also possible to divide it into three parts, for example, in a so-called double-door style. In this case, changes such as making the grain supply port 44 removable are required.

Further, in FIG. 1, the opening angle of the door portion 46 is approximately 180 degrees, but in reality, an opening angle of slightly more than 90 degrees is sufficient as the opening angle at which removal is possible.

"Effects of the Invention" According to the vertical grain sorting machine according to the present invention, the upper body of the outer shell can be opened widely, and the spindle for driving the conventional sorting net does not penetrate into the center of rotation. ,
Since the connection between the upper and lower drive motors can be easily released, it is now possible to take out the sorting mesh body and the grain frying spiral body laterally outside the machine, which greatly improves the work efficiency of replacement, making it extremely user-friendly. It will be good.

In addition, in the technology shown in the embodiment, the motors for driving the sorting net and the grain-lifting spiral are provided separately and independently, and at least the rotation speed of the grain-lifting spiral can be freely changed. It has become possible to significantly improve the accuracy of grain sorting due to the ease of selection and exchange of grains.
