Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sample paddy drying apparatus in a grain joint drying and adjustment facility such as a so-called rice center.

At the joint drying adjustment facility, in order to determine the quality of the unhulled rice brought in by Canadian farmers, self-inspections are carried out on the hulling ratio, waste rice ratio, etc. Conventionally, the drying equipment for self-inspection is a dryer that weighs a predetermined amount. Samples of paddy were manually put into a test dryer, dried for a predetermined period of time, and then manually removed from the test dryer to inspect the hulling ratio, waste rice ratio, etc., but the work efficiency was poor. (It was inefficient.

Of this series of steps, the task of removing the samples from the dryer is particularly complicated.For example, it is conceivable to prepare a large number of sample boxes, put the samples in each one, and take them out when a predetermined amount of drying has been performed. However, in this case, if the sample rice that has already been dried is left unattended, it may become over-dried, resulting in a significant drop in work efficiency.

This also applies even if an overdrying prevention device is installed. Additionally, an operator must be present next to the dryer at all times to monitor which sample paddy is to be taken out after drying is complete.

In particular, the present invention is intended to facilitate the operation of taking out sample rice from the dryer, thereby solving the inefficiency of having a person constantly present during the drying operation.

In order to feed the paddy amount set in step 2 (sample paddy amount standard value) to the conveyor side chute 15a, the switching valve 23 is switched to open the conveyor side chute 15a, and the chute 15
When a predetermined amount of paddy is fed to the chute 15b, the changeover valve 23 is switched to open the recovery chute 15b in order to feed the remaining paddy in the weighing section 21 to the recovery chute 15b.

On the upstream side of the conveyor side shoe H5a, there is a receiving box 6.6.
... is provided with a receiving box sensor 5 that detects when the conveyor side chute 15a has reached just below the tip opening,
The shutter 4 is opened and closed based on the detection result of the receiving box sensor 5.

A heater 8 is provided below the upstream side of the conveyor 7, and the acid heater 8 connects the air in the detection 9 to the receiving boxes 6, 6.
...Drying the sample paddy inside.

A suction fan 10 is provided above the downstream side of the conveyor 7, and the air inside the casing 9, which has been heated by the heater 8 and humidified by the evaporation of moisture in the sample rice, is passed through the duct 14 of the suction fan 10. It will be discharged outside,
Moisture removal from the sample rice in the receiving boxes 6, 6, . . . is promoted.

On the inner surface of the casing 9 on both sides of the conveyor 7, there are wind shield plates 13, 13...
are provided at several locations, and on the inner surface of the casing 9 on the upstream side of the conveyor 7, a wind shield plate 11 is provided approximately horizontally to suppress the flow of air in this area, and similarly on the downstream side of the conveyor 7. A wind shielding plate 11 is also provided almost vertically on the upper side of the end to suppress the flow of air in this area, and the air heated by the heater 8 is passed through the receiving boxes 6, 6... A current is passed through the sample rice to ensure that the rice is dried and then discharged from the duct 14 of the suction fan 10. Further, below the downstream end of the conveyor 7, a discharge hopper 12 is provided for discharging the dried sample rice.

The apparatus of the present invention constructed as described above is used and operated as follows. When a desired amount of paddy is put into the hopper L, the quantitative cutting device 2 measures the amount set in the setting section 22 and drops it to the shaft 4 of the conveyor side chute 15a.
The remaining amount is taken out from the tip opening of the collection chute 15b to the collection hopper by operating the switching valve 23. The shafter 4 is opened according to the detection result of the receiving box sensor 5, and one receiving box 6 is placed in the chute 15a on the conveyor side. When the receiving box sensor 5- detects that the tip opening has been reached, the shafter 4 is opened and a predetermined amount of paddy is thrown into the receiving box 6. The speed of the conveyor 7 is adjusted by a speed reducer (not shown) and is driven at a predetermined speed, and the receiving box 6 is also transferred downstream at the same speed.

On the other hand, the inside of the casing 9 is heated by the heater 8 located on the upstream side, and the humidified air inside the casing 9 after drying the paddy is discharged to the outside by the suction fan 10 located on the downstream side. , the air inside the casing 9 flows as indicated by the arrows in FIG. 1.2. Therefore heater 8
