DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the outline of the soybean drying equipment.
A plurality of round bins 1 for grain storage can be supplied with soybeans from the elevator 2, and each round bin 1, 1 ...
Are configured to be able to supply air from the blower 3 so that the soybeans supplied to the round bottles 1, 1,. Reference numeral 4 denotes a discharge conveyor, which is the above-described elevator 2.
Connected to. In addition, the elevator 2 is in each bin 1, 1
, And can supply and discharge dried grains to the outside of the machine as appropriate.

The round bottles 1, 1... Have the following configuration. The bottle 1 is provided with a gas-permeable inner cylinder 6 having an appropriate diameter inside a cylindrical outer cylinder 5, and a space is formed in a space between the outer cylinder 5 and the inner cylinder 6. In order to receive the distribution of soybeans from the section and store the soybeans, zigzag-shaped guide passages 7 are provided at three equally spaced positions in plan view in the vertical direction. The guide passages 7 are formed by combining shelf members 8, 8... Alternately from the left and right sides so as to face each other, and are formed so as to have a substantially square cross section.
8 are vertical wall portions 8a, 8a, and swash plate portions 8b, 8b. Also, overflow ports 8c are formed between the upper and lower portions of each shelf member.

At the upper center of the round bottles 1, 1,..., There is provided a hopper 11 which receives the soybeans from a stake conveyor 10 which is connected to the stake elevator 2 and supplies soybeans to the bins 1, 1,. Have. The hopper 11 has a circular cross section,
A flow regulating body 1 having a pair of upper and lower conical bodies formed in an abutting manner at an inner central portion of a gradually decreasing diameter portion on the lower side thereof.
2 is configured so as to be vertically adjustable along the vertical center axis of the adjusting body 12 so that the interval (a) between the outer periphery of the cone and the inner surface of the hopper 11 can be adjusted widely. That is,
At the center of the flow rate adjusting body 12, there is provided a screw rod 13 which also serves as a suspension, and a reversible motor 14 screwed to the screw rod 13 is connected. When the motor 14 rotates in the forward direction, the space (a) is enlarged. In the reverse rotation, this can be reduced.

The lower surface of the hopper 11 and the guide passages 7,
7 between the guide chutes 15, 15, 1
5 so that the discharge can be guided substantially uniformly in the direction of each guide chute by the flow rate adjusting body 12.

The lower ends of the guide passages 7, 7,... Are provided close to the air-permeable floor surface 16 and are filled in the guide passages 7 from below while sequentially guiding the cereals to be dried. When they reach the overflow ports 8c, 8c, they overflow and the outer cylinder 5 and the inner cylinder 6
This is a configuration in which it is deposited in the space between the two.

Further, an opening / closing shutter 17 for discharging from the bin is provided, and by opening the shutter, the shutter can be discharged from a discharge port 18 provided at one place on the floor 16. The floor 16 is in the form of a so-called sweep floor, which is breathable. The soybean in a small amount is supplied with air from the ventilation section 19 on the lower surface and is guided toward the discharge port 18. In addition,
The following improvements have been made to promote the flow of soybeans. For example, corner covers 20 and 21 may be provided at the connection portion between the floor surface 16 and the outer cylinder 5 to the inner cylinder 6 (FIG. 4), or the floor surface 16 may have a lower outlet 18 side, for example, about 5 °.
It is intended to promote discharge by making a downward slope (Fig. 5).

A discharge chute 22 is connected between the discharge port 18 and the discharge conveyor 4. In other words, the discharge conveyor 4 is in the form of a belt conveyor and receives soybeans. In a small amount receiving state, the soybeans scatter on the conveyor surface and roll, so that the soybeans easily fall out of the transport zone. In order that the soybean supply amount from the discharge chute 22 to the four conveyors can be supplied in a certain state,
A shutter 23 is provided in the middle of the discharge chute 22 to close the shutter 23 in anticipation of a small discharge state and to open the shutter 23 in anticipation of a predetermined amount of stagnation. The operation of the shutter 23 is an electromagnetic solenoid type or a forward / reverse rotation motor, and the operating member is controlled to discharge a predetermined amount or more while detecting the presence or absence of the predetermined amount of stagnation through detection means. May be.

Level detectors 24 and 25 are provided above and below the hopper 11, and expiration detectors 26 are provided at the grain expiration position of the round bottle 1. The controller (not shown) controls the insertion conveyor 10, Including elevator 2,
The weighing machine (not shown) on the upper side of the elevator 2 and the hopper shutter 27 below the hopper 11 can be driven or opened and closed. An example of the control is as follows. When the expiration detecting means 26 is off, weighing is enabled by the weighing machine. When the level low detecting means 25 is on, the hopper shutter 27 is opened. For example, the discharge from the machine is stopped, or when the expiration detecting means 26 is turned on, the metering and payout is stopped. In this way, by providing the level detection in each section, a command signal can be output at the preceding stage, and wasteful grain discharge and conveyance can be prevented. As a result, proper automation could not be performed due to poor leveling and the like as compared with the conventional configuration in which the level was detected by the level detecting means on the round bottle 1 side of the main body.
By arranging the level high / low detection means in the section, the grain filling state can be constantly maintained in the hopper 11 and the planned capacity can be reliably supplied.

The operation of the above example will be described. By operating the switch for loading operation provided in the controller (not shown), each loading section is activated, and the soybeans to be dried are appropriately passed through the loading elevator 2, the loading conveyor 10 and the round bottles 1, 1,.
Transported to be supplied to Hopper 1 for each round bottle 1, 1, ...
The soybeans received in one part flow down the interval part (a) adjusted by the flow rate adjusting body 12, and pass through the guide chutes 15, 15, 15 extending in three directions to form the guide passage parts 7, 7, 7 in a zigzag shape. The flow speed is reduced and soybean damage can be prevented. It accumulates on the floor 16 from the lower end of the guide passage 7,
.. Overflow from the overflow ports 8c, 8c,... Of the guide passage portion 7 and accumulate and accumulate in the space between the outer cylinder 5 and the inner cylinder 6.

Since the flow rate adjusting body 12 can adjust the interval (a) to be wide and narrow by the reversible motor 14, the interval is adjusted in consideration of the amount of penetration per unit time, the water content, and other properties of soybeans. Is what you do. The controller (not shown) is provided with various switches for normal rotation and reverse rotation of the motor 14 in addition to various operation start switches, and manually adjusts the distance (a) to adjust the gap (a).

When the soybean filling is completed, a ventilation drying operation is started. When the ventilation drying operation switch of the controller (not shown) is turned on, the blower 3 and the like are also activated, and the ventilation unit 1 under the floor surface 16 is opened.
The drying air is blown through 9. The blast air blows up from the floor and enters the permeable inner cylinder 6, and is exhausted from the outer cylinder 5 between the cylindrical outer cylinder 5 and the inner cylinder 6 and across the guide passages 7, 7, 7. By this ventilation, the stored soybeans inside are gradually dried. That is, the drying air enters from the inner cylinder 6 and acts on the soybeans, while the soybeans stagnating on the shelf members 8, 8,.

Whether or not the sample is dried to a predetermined moisture value is determined by measuring the moisture of the sample grains appropriately sampled. The sampling configuration is such that a main cylinder 25 partially open in the longitudinal direction is placed at an appropriate position in the guide passage portion 7 in a substantially horizontal posture between the outer cylinder 5 and the inner cylinder 6 so as to penetrate the opposing shelf members 8. And a sample tube 26 that can be inserted into the main tube 25 is also provided with its longitudinal direction partially open. When the sample cylinder 26 is inserted into the main cylinder 25 and the opening portions are aligned with each other and turned to the upper surface, the soybean to be dried can be received in the sample cylinder 26 side. Measure with a meter. The main cylinder 25 is always inverted so that the open portion faces downward, thereby facilitating the insertion of the sample cylinder 26 in the next measurement. As described above, if the sample passage 26 is used to sample the guide passage portion 7 in a transverse direction, drying is relatively accelerated on the side closer to the inner cylinder 6 and drying on the side closer to the outer cylinder 5 is delayed. Also allows for average sampling
Improve the accuracy of grasping the dry state.

When dried to a predetermined moisture value, the soybeans are discharged outside the machine. When the opening / closing shutter 17 is opened, the soybeans sequentially flow into the floor 16 in an overflowing manner and are discharged from the soybeans near the discharge port 18. . Finally, when the amount becomes small, it is made to flow by aeration and promotes movement to the outlet 18.

In the above-described embodiment, the configuration is such that the blower 3 is used for drying alone. However, a configuration in which hot air can be supplied in combination with a heater may be used to increase the drying speed.

When stacking in multiple stages, the grains in the upper stage are sequentially shifted to lower positions to promote reversal and promote even drying. The ventilation air to the blower 35 at one end of the air tube 34 is supplied to the greening chamber 30 so that the heating air by the heater of the greening chamber 30 can be taken in.
And the grain drying facility are connected via a duct 37. As described above, since the heater heated air in the greening chamber 30 can be used for the drying preparation, the initial cost can be reduced by effectively utilizing the existing equipment, the running cost during drying can be reduced, and the operating rate of the existing equipment can be reduced. There are effects such as contributing to improvement.
