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.

The joint drying and adjustment facility conducts voluntary inspections of the hulling ratio, waste rice ratio, etc. in order to determine the quality of the paddy rice brought in by member farmers. Conventionally, as a drying device for self-inspection, a predetermined amount of sample paddy is weighed and put into a test dryer, and after drying for a predetermined time, it is taken out from the test dryer and the rice grain ratio, scrap rice ratio, etc. However, the work was difficult and inefficient.

Among this series of steps, the work of removing the product from the dryer is particularly complicated. For example, it is conceivable to prepare a large number of sample boxes, put samples in each one, and take them out after 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.

The purpose of the present invention is to provide a sample paddy drying device that facilitates the work of taking out the sample paddy from the dryer, eliminates the inefficiency of having a person constantly present during the drying process, and achieves automation. do.

The switching valve 23 is switched to open the conveyor side chute 15a to feed the conveyor side chute 15a, and when a predetermined amount is fed to the chute 15a,
The switching valve 23 is switched to send the remaining paddy in the weighing section 21 to the collection chute 15b.
Open 5b. When paddy is put into the hopper 1, a code for identifying the paddy to be inspected (a code for identifying the farmer, a receiving code, etc.) is given to the control unit 24 in association with the drive system of the conveyor 7. ，
6. Tracking of paddy stored in... In this way, the control unit 24 functions as a supply control device that supplies sample paddy to the conveyor in batches and holds information for specifying the supplied sample paddy.

At the upstream side of the conveyor side chute 15a, there is a receiving box sensor 5 that detects when the receiving boxes 6, 6, . . .
is provided, and 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 heater 8 connects the air in the detection 9 to dry the sample rice in the receiving boxes 6, 6, . . . 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. This will facilitate the removal of moisture from the sample rice in the receiving boxes 6, 6, . . . .

On the inner surface of the casing 9 on both sides of the conveyor 7,
Wind shield plate 1 to suppress air circulation in this area.
3, 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 installed approximately horizontally to suppress the flow of air in this area. A wind shielding plate 11 is also provided substantially vertically above the downstream end of 7 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, . . . duct 1 of the suction fan 10.
4, it is now being discharged. 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 1, the quantitative cutting device 2 measures the amount set in the setting section 22 and drops it to the shutter 4 of the conveyor side chute 15a, and the remaining amount is measured by the switching valve 23. By operation, it is taken out from the opening at the tip of the collection chute 15b to the collection hopper. The shutter 4 is opened based on the detection result of the receiving box sensor 5. When the receiving box sensor 5 detects that one receiving box 6 has reached the tip opening of the conveyor side chute 15a, the shutter 4 is opened. A predetermined amount of paddy is put 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 a heater 8 located on the upstream side, and the humidified air inside the casing 9 after drying the paddy is exhausted to the outside by a suction fan 10 located on the downstream side. Because there are
Air within the casing 9 flows as indicated by arrows in FIGS. 1 and 2. Therefore, the air heated by the heater 8 flows through the netted portion of the conveyor 7 and the netted bottom of the receiving box 6, and the paddy inside the receiving box 6 is dried while being transferred by the conveyor 7 and sent to the discharge hopper. 12 and put into a predetermined inspection device or the like.

In this case, since the blow-through of the heated air is suppressed by the wind shield plates 13, 13, . The flow will be carried out through the
Paddy is dried efficiently.

Since the amount of water removed by the device of the present invention depends on the time during which it is transferred by the conveyor 7, drying is done by adjusting the speed of the conveyor 7 and the heat generation amount of the heater 8 while keeping the suction capacity of the fan 10 constant. The rate can be controlled.

Furthermore, when using the apparatus of the present invention, it becomes possible to automate drying and self-inspection.
