The hopper (33) is provided so as to move in the horizontal direction along with the hopper (33) at a predetermined empty container (32) position based on a command signal output from the centralized controller (12). The motors (47) and (50) are drive-controlled in order to guide the movement.

By the way, as shown in FIG. 4, the sample container (32) has a lower portion (32a) and a bottom shutter (5).
1) is formed of a net, and the lower part (32a) and the shutter (51) have air permeability and the container (3).
The upper opening (32b) of 2) is provided with the upper lid (54) via the shaft (52) and the torsion spring (53), and the spring (5
3) The upper lid (54) is closed and held at the position of the regulating member (55) by force, and the container (3) is removed from the hopper (33).
2) When the paddy is put into the inside, the upper lid (54) is forcibly opened against the force of the spring (53) by the weight of the paddy. After a certain amount of paddy has been put into the container (32), the pad (5) is covered with these paddy.
4) is configured so that the open state is maintained and the hot air flowing in from the mesh of the lower part (32a) and the bottom plate (51) absorbs moisture in the paddy while passing through the accumulated layer of these paddy. There is. The shutter (51) is a solenoid (56).
The solenoid (56) is configured to open and close the shutter (51) with excitation and de-excitation.

Further, a shutter (57) is provided at the discharge port of the moving hopper (33), and the opening / closing operation is performed by a solenoid (58). Further, a moisture sensor (61) is vertically movably supported on the hopper (33) through a forward / reverse motor (59) and an adjusting screw shaft (60), and a certain drying time elapses according to moisture conversion when receiving a load. After that, the sensor (61) is put into an operating state, the water content of the sample paddy is detected based on the change in the capacitance, and when the paddy is dried in the set state, the solenoid (5
The shutter (51) is opened via 6). When any one of the shutters (51) in the container (32) is in the open state, the shutters (51) of the other containers (32) maintain the closed state.

Further, in each of the above-mentioned embodiments, the constitution using the moisture sensor (61) is shown. However, without using the sensor (61), the test dryer (18) is set only by setting the drying time based on the initial moisture detection. It may be configured to take out more sampled paddy.

This embodiment is constructed as described above, and is installed in a rice center, a country elevator, a dry store, etc., and the raw rice harvested by the combine or the like is applied to the load receiving and weighing machine (3) for each individual and each shipping port. Along with the addition, a scaler (1
5) and a fixed amount of the homogenized sample paddy are taken out to the sample transfer device (17) through the metering branch valve (16), while the sample paddy of the transfer device (17) is set by the test dryer (18). It is dried to the amount of water, and the dried sample paddy is put into the self-inspection machine (27) to measure the ratio of the unpolished rice and the scrapped rice, and the ratio between these is calculated. Based on the voluntary inspection data of the sample paddy corresponding to the consignment number, the proportion of smoothed brown rice for each individual and for each cargo is registered in the office computing unit (11).

During such work, the test dryer (18)
The sample paddy put in the input port (21) of the above is once received by the moving hopper (33) which is held at the lower position of the input port (21) when the traveling is stopped normally, and then the central controller (12). Based on the command signal from the traveling device (43)
Is operated to move the movable hopper (33) to a predetermined container (32) position in the empty state, and when the hopper (33) reaches the predetermined container (32) position, the solenoid (5
8) The shutter (57) is opened by the operation, and the sample paddy is discharged from the hopper (33) into the container (32). When a certain amount or more of the sampled paddy is discharged and the paddling weight overcomes the force of the spring (53), the upper lid (54) of the container (32) is forcibly opened and placed in the container (32). The sample paddy from the hopper (33) is put up, and thereafter the paddy group put up holds the upper lid (54) open as shown by the phantom line in FIG. After that, the amount of heat of the timer is converted to the amount of moisture when receiving the cargo, and the amount of heat is supplied by hot air to evaporate the moisture and reduce the moisture content in the paddy to the set value. When the moisture sensor (61) detects the moisture content and confirms the set value of the moisture content, the shutter (5) is operated by operating the solenoid (56).
1) is opened and the sample paddy in the container (32) is discharged onto the conveyor (35), and the conveyor (35)
At the end of this movement, the paddy discharged to the top is discharged to the discharge conveyor (3
6) and taken out to the outside of the test dryer (18) from the delivery port (23).

Further, FIG. 5 shows another modified structure example, in which a plurality of heaters (38a) are arranged in a substantially uniform state over the entire lower portion of each sample container (32). In addition, a plurality of exhaust fans (40a) are arranged above each container (32), and a stationary moisture sensor (61) is fixedly installed at the delivery port (23). Of the sensor (6
1), and when the set water content is not reached, it may be returned to the charging port (21) again via the electromagnetic switching branch valve (62).

Further, FIG. 6 shows the above-mentioned conveyor (35).
(36) Replace the moving hopper (33) with each container (3
2) ... An example of a configuration further arranged below is shown, and both of the filling of the sample paddy into the respective containers (32) and the removal thereof can be performed by the moving hoppers (33) (33), and the structure can be made compact. . Further, by assembling the test dryers (18) ... Into a single unit frame (63), centralized control can be achieved in the drying work.
