Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cereal co-drying facility such as a country elevator for collectively drying and storing received cereals such as rice or wheat.

[0002]

In a pool-type co-drying facility for collectively drying grain brought in from each farmer, a facility for measuring the amount of cargo received by each truck on a truck scale is used for voluntary inspection ( (Moisture measurement and quality inspection) when extracting a fixed amount of sample grain is performed manually.

[0003] However, in a truck scale introduced for the purpose of improving the efficiency of receiving goods, such a manual operation requires much labor and time, so that it is impossible to expect the real efficiency of receiving goods. In addition, in the case of such a manual operation, voluntary inspection can be performed only on a sample grain from a part of the surface layer of the grain brought into the receiving hopper, etc. Inconveniences such as loss.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention comprises a receiving hopper for charging grain after receiving and weighing it on a truck scale, and a receiving hopper for sampling a part of the grain input to the receiving hopper. And automatically and reliably collect a part of the grain as a sample from the received grain in the receiving hopper loaded from the truck scale, and eliminate the need for conventional sample collection personnel, for example, to perform self-inspection. This makes it possible to increase the efficiency of sampling for use.

Also, a sample tank is provided for taking out a fixed amount of sample grains from the grains conveyed on the sample conveyor as sample grains for self-inspection, and a certain amount of sample grains required for self-inspection from the grains conveyed on the sample conveyor is provided. It is intended to take out accurately and improve the efficiency and accuracy of voluntary inspection.

[0006] Further, a sample adjusting valve is provided for adjusting the amount of sample grains fed from the sample conveyor to the sample tank during sample introduction, and sample grains are evenly collected from all the received grains to be collected. And the accuracy of the self-inspection is improved.

As shown in FIG. 2 to FIG. 5, the sample tank (12) has a lower part branched so that an excess paddy discharge part (21) is formed.
And the sample paddy discharge section (22), and the lower discharge port (21a) of the excess paddy discharge section (21) faces the upper side of the receiving belt conveyor (5), and the lower discharge port of the fixed discharge section (22). (22a) is a sample transfer conveyor (13)
It is configured to face upward.

An automatic sample adjusting valve (24) is provided at the paddy receiving port (23) above the sample tank (12) to adjust the inflow amount of the sample paddy flowing into the fixed amount discharging section (22). The lower and upper automatic sample taking shutters (2
5) (26) and lower and upper sample level sensors (27) and (28) are provided, sample paddy is collected and collected between the lower and upper shutters (25) and (26), and a sample dryer is prepared as a quantitative sample paddy. It is configured to be conveyed to (19).

As shown in FIG. 5, the receiving hopper (2)
In (3), the lower part of the conveyer trough (29), which arranges the lower peripheral side of the sample conveyor (12), and the residual treatment plate (30), which opens one side, are conveyer trough via hinges (31). The cylinder (35) is provided on the conveyor frame (32) in the receiving hoppers (2) and (3) via a bracket (33) and a pivot shaft (34) so as to swing freely.
The tip of the piston rod (36) of the cylinder (35) is connected to the processing plate (30), and when one loading port is completed, the processing plate (30) is opened by the cylinder (35). The sample paddy remaining on the conveyor gutter (39) is dropped downward to receive the hopper (2) (3)
It is configured to return to. The outlet (29a) is connected to the receiving gutter (29) at the sending end of the sample conveyor (11).
And open the sample tank (1
The sample paddy is dropped and supplied to the paddy receiving port (23) of 2).

Also, when a fixed amount of sample paddy is collected between the shutters (25) and (26) in the sample tank (12), the excess portion after that is discharged to the excess paddy discharge section (21) and the automatic receiving shutter (37). And is returned to the load receiving belt conveyor (5) of the present line via the.

Incidentally, (38) is a receiving hopper (2) (3)

In addition, a sample tank (12) is provided for taking out a quantitative amount from the paddy conveyed on the sample conveyer (11) as a sample pad for self-inspection, and a self-inspection is performed from the paddy conveyed on the sample conveyer (11). It is possible to accurately and automatically take out a required amount of sample paddy to improve the efficiency and accuracy of voluntary inspection.

Further, a sample adjusting valve (24) for adjusting the input amount of the sample paddy from the sample conveyor (11) to the sample tank (12) is provided, and the truck scale (1) receives the load receiving hopper (2) ( During the receiving work to 3), collect the sample paddy uniformly from all the paddy received by the adjustment of the regulating valve (24), improve the representativeness of the self-inspection data, and improve the self-inspection accuracy. The risk of loss of the facility owner in the checkout operation is improved.

[0017]

As is apparent from the above embodiments, the present invention includes the receiving hoppers (2) and (3) for charging the weighed grain by the truck scale (1) and the receiving hoppers (2) and (3). ), A sample conveyor (11) for sampling a part of the cereal fed into the receiving hopper (2).
Since it is provided in (3), a part of the grain is automatically and reliably sampled from the grain received in the receiving hopper (2) (3) input from the truck scale (1). This makes it possible to increase the efficiency of sample collection for voluntary inspection by eliminating the need for conventional sample collection personnel.

Further, since a sample tank (12) for taking out a fixed amount from the grain conveyed by the sample conveyor (11) as a sample grain for voluntary inspection is provided,
It is possible to accurately take out a certain amount of sample grains required for the self-inspection from the grains conveyed by the sample conveyor (11) and improve the efficiency and accuracy of the self-inspection.

Further, since a sample adjusting valve (24) is provided for adjusting the amount of the sample grains fed from the sample conveyor (11) to the sample tank (12), the amount of the received grains is reduced. By collecting sample grains evenly, it is possible to enhance the representativeness of the self-inspection data and improve the self-inspection accuracy.
