1 to 4 show an embodiment of the present invention. The structure of the embodiment will be described with reference to the drawings. Machine casing, (2) is the bottom plate of machine casing (1), (3)
Is a supply unit provided at the center in the left-right direction of the machine housing (1), and a chevron-shaped chain cover (4) inclined forward and backward at an inner center in a front-rear direction perpendicular to the longitudinal direction of the machine housing (1). A passage (5) is formed in the front and rear bifurcated passage (5) provided with a groove so as to flow into the machine housing (1) from the front and rear direction orthogonal to the grain conveying direction.
Are connected to openings (6) provided at intermediate positions in the vertical direction of the front and rear walls of the machine housing (1).

(7) and (8) are left and right non-shutter discharge units provided at the bottoms of the right and left ends of the machine housing (1), respectively.
(9) and (10) are left and right sprockets respectively mounted on left and right ends of the machine casing (1) by left and right sprocket shafts (11) and (12), and (13) and (14) are machine casings (1). Left and right motors mounted on both left and right ends of the left and right sprocket shafts (11) and the front protruding portion of the left sprocket shaft (11) by the left chain transmission mechanism (16). The rotation shaft (17) of (14) and the front protrusion of the right sprocket shaft (12) are connected by the right chain transmission mechanism (18), respectively.

(A) shows left and right sprockets (9) and (1).
The reference numeral 0 denotes a conveyor chain, wherein (19) is a blade of the conveyor chain (a), (20) is a lower piece of the conveyor chain (a), and is placed on the bottom plate (2).
(21) is an upper piece of the conveyor chain (a) which is supported by guide rollers (22) arranged at appropriate intervals, and in which grains flowing into the machine housing (1) from the opening (6) are conveyed by the conveyor chain (a). The upper piece (21) passes through the inside of the chain cover (4) as shown in FIG. 3 so that the upper piece (21) is not discharged from the non-predetermined non-conveying side shutterless discharge section on the upper piece (21). It is arranged above the opening (6).

Although not shown, an inverter is provided in an electric circuit formed on the left and right motors (13) and (14).
Over the provided motor (13) start-up time of 5 seconds or more, to set the fall time than 10 seconds. (23) is a discharge unit with a shutter provided at an appropriate place in the middle of the bottom plate (2), and (24) is a deflection generated in a lower piece of the conveyor chain (a).

The operation will be described. When the grain is transported from the supply section (3) to the left shutter-less discharge section (7), the left motor (13) on the driving side is energized and the left motor (13) is rotated leftward from the rotating shaft (15) of the left motor (13). The left sprocket (9) rotates in the direction of the arrow in FIG. 2 via the chain transmission mechanism (16) and the left sprocket shaft (11), and the conveyor chain (a) rotates in the direction of the arrow in FIG.

Therefore, when grains such as brown rice are put into the supply section (3), the grains are divided into both front and rear passages (5) in the supply section (3) and pass through both passages (5). The blades (1) of the lower piece (20) of the conveyor chain (a) fall from the front and rear openings (6) to the bottom plate (2) of the machine housing (1).
According to 9), it is pushed to the left along the bottom plate (2) and falls from the left shutterless discharge section (7) to be discharged.

On the other hand, left and right motors (13) and (14)
Since there is no clutch device, when the above-mentioned grain is conveyed to the left-side non-shutter discharge section (7), the conveyor chain (a) driven and rotated by the left-side motor (13) on the driving side rotates the right-side sprocket on the non-driving side. (10), right sprocket shaft (12), right chain transmission mechanism (1
After 8), the conveyor chain (a) rotates while the rotation shaft (17) of the right motor (14) is not rotating by itself but spinning with another force.

At this time, the right side motor (1
Since the rotating shaft (17) of 4) is spinning with another force, an inverter having a starting time of 5 seconds or more and a falling time of 10 seconds or more is provided in the electric circuit to the left and right motors (13) and (14). Otherwise, during the transfer of the grains in the left direction, the left shaft of the left motor (13) is driven for a certain time by driving the rotation shaft (15) of the left motor (13), and then the rotation shaft (15) of the left motor (13). When the operation of the motor is stopped, the rotation axis (17) of the non-drive-side right motor (14) does not stop immediately due to the power generation phenomenon and inertial rotation due to idle rotation, and the rotation axis of the drive-side left motor (13). There is a stop time difference between the stop of (15) and the stop time difference, the stop time difference being 0 seconds and 39 delays, and the right sprocket (10) on the non-drive side rotates about 70 ° more after the stop of the left sprocket (9) on the drive side. And stop.

[0017] To this end, the drive side of the left side motor (1
When the rotary shaft (15) is stopped in (3), the lower piece of the conveyor chain (a) bends (24) below the non-driven side right sprocket (10) as shown in FIG. The engagement between the teeth of (10) and the rollers of the conveyor chain (a) is released from the normal state, and the conveyor chain (a) and the bottom plate (2) of the machine housing (1) are removed when the conveyor chain (a) is restarted. Damage may occur. The test data is as follows. (Test data) (1) Chain conveyor length 12900mm (2) Gear motor [2 units] 1.5 kW 1/45 (3) Driving motor stop time 0 seconds 68 (4) Non-drive motor stop time 1 07 (5) Stop time between the drive side motor and the non-drive side motor 0 seconds 39 (6) Emission voltage of the non-drive side motor 2.82V

However, according to the present invention, as a countermeasure against the above-mentioned trouble, a start-up time of 5 seconds or more and a fall time of 1 in an electric circuit formed on the left and right motors (13) and (14).
An inverter set for 0 seconds or longer was provided. Therefore,

By operating the inverter with a fall time of 10 seconds or more, the drive-side left motor (13)
When the operation of the left motor (13) is stopped.
In 5), since the rotation gradually decreases and stops quietly, the rotation axis (17) of the right side motor (14) on the non-drive side also stops simultaneously with the rotation axis (15) of the left side motor (13) on the drive side. There is no power generation phenomenon and free-wheeling rotation that cause trouble.

Accordingly, the right sprocket (10) on the non-drive side of the conveyor chain (a) also stops at the same time as the left sprocket (9) on the drive side, so that as shown in FIG. 20) is stopped in a normal straight state, so that the deflection (24) of the conveyor chain (a) as shown below the right sprocket (10) in FIG. 4 does not occur. Therefore, the restart of the conveyor chain (a) can also be performed smoothly.

Further, when the inverter is operated with the start-up time set to 5 seconds or more, a reliable operation without any trouble and a silent operation can be performed both when starting and stopping the conveyor chain (a).

On the other hand, when the grains are conveyed from the supply section (3) to the right shutter-free discharge section (8) in the opposite manner,
When the right motor (14) on the driving side is energized, the conveyor chain from the rotating shaft (17) of the right motor (14) passes through the right chain transmission mechanism (18), the right sprocket shaft (12), and the right sprocket (10). (A) rotates in the direction opposite to the arrow in FIG.

Accordingly, when the grains are put into the supply section (3), the grains operate in the same manner as described above and are sequentially pushed rightward by the blades (19) of the lower piece (20) of the conveyor chain (a). Then, it is dropped and discharged from the right shutterless discharge section (8).

At this time, although the rotation shaft (15) of the non-drive-side left motor (13) is idle, the drive-side right motor (14) is stopped when the operation is stopped.
The same operation as above is performed, and the left and right motors (13), (1)
The rotation shafts (15) and (17) of 4) gradually decrease in rotation and stop quietly at the same time, so that the power generation phenomenon and the inertial rotation which cause trouble do not occur.

It is to be noted that a required number of discharge units with a shutter (23) may be provided at an appropriate interval in an intermediate portion of the machine housing (1), or a required number of supply units (3) may be provided at an appropriate interval.

FIGS. 5 and 6 show another embodiment of the supply section of the machine (1) according to the present invention. The configuration of the supply section will be described with reference to the drawings. It is arranged at the front of the center in the left-right direction of the machine housing (1) so as to flow into the machine housing (1) only from the front orthogonal to the transport direction of the grains, and is arranged in the vertical direction of the front wall of the machine housing (1) The lower end of the supply section (3a) is connected to the opening (6) provided at the intermediate position. Other symbols indicate the same parts as in FIGS. 1 to 4.

In this structure, when the grains are put into the supply section (3a), the grains are lowered in the supply section (3a) and from the opening (6) to the bottom plate (1) of the machine housing (1). 2) It goes up, and thereafter it works in the same way as above.

The supply section (3a) is disposed on the rear side of the center of the machine casing (1) in the left-right direction, and the supply section (3a) is provided in an opening provided in the rear wall of the machine casing (1). When the lower ends are connected, the same operation as described above is performed.
