[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain quantity control device for managing the quantity of grain stored in a storage silo installed in a grain drying facility.

[0002]

2. Description of the Related Art Grains received in a grain drying facility are sequentially weighed by a receiving and weighing machine, and the weighed grains are supplied, for example, to a predetermined storage silo for each product type, and dried in a later step, drying. Until the start of work, temporarily stored in this storage silo, and dried kernels are supplied to a weighing machine and weighed, and the weighed kernels are supplied to the specified storage silo for each product type. Until the start of the hulling work in the post-process, the grain is temporarily stored in the storage silo or the dried grain is not measured without being supplied to the grain weighing machine. Until the hulling work, which is a post-process, is temporarily stored in this storage silo, or grains that are being dried are temporarily supplied to the predetermined storage silo by type and supplied to the predetermined storage silo by type. Storage and transfer of the stored grain between the storage silos. It is carried out.

[0003] The amount of grain supplied to the storage silo is detected by detecting the height of the grain using a weight-suspended detection device, and converting the weight of the grain from the detected height of the grain. . These detected grain height, grain weight obtained by conversion,
The grain weight and the like measured and stored by the grain weighing machine are displayed on the display means. Further, when the grains measured by the grain weighing machine are additionally supplied into the storage silo storing the grains whose grain weight is converted from the detected grain layer height, the converted grains obtained by the conversion The weight obtained by the weighing is added to the weight, and the weight of the grain stored in the storage silo is detected. Further, the bed height up to the grains additionally supplied into the storage silo is detected by the detection device. Both the detected grain height and the stored grain weight are displayed on the display means.

The weight of the grain stored without measuring the supply weight supplied into the storage silo is converted into a grain weight based on the height of the grain bed detected by the detecting device. When the weighed weight measured by the grain weighing machine is additionally supplied into the silo, the weight of the stored grain is added by adding the weighed weight obtained by the weighing to the weight of the grain obtained by the conversion. , The converted weight and the measured weight are added, and an accurate grain weight cannot be obtained. Therefore, the inside of the storage silo cannot be accurately filled, or the detection device has a weight. This is a hanging system, which requires a long time for detection. However, the present invention is intended to solve these problems.

110), if YES is determined, the converted weight is replaced with the weighed weight detected by the grain weighing machine 62 (S-11).
1) Discharge is detected from the storage silo 39 (S-11).
2) If YES is determined, the data of the grain weighing machine 62 is fetched (S-113), and it is detected whether the grain type is the same as the grain displayed on the display means 10 (S-114), and the determination is NO. Then, error processing is performed (S-115). If it is determined to be YES, the weight is subtracted (S-116), displayed on the display means 10 (S-117), and the storage silo 39 for display is changed (S-118) and (S-118). 1
02).

A determination of YES is made in (S-102), and (S-1)
If the determination is NO in 03) and the determination is NO in (S-112), the process proceeds to (S-117). NO at (S-104)
Is determined, and if NO is determined in (S-110), (S
Go to -112). As shown in FIGS. 7 to 9, in the grain drying facility 1, when the transfer device for transferring the grains uses the flow conveyor 73,
It comprises a drive side case 74a, a driven side case 74b, and an intermediate case 74c.
74c, a transfer chain 75a equipped with a plurality of moving tools 75b on both front and rear sides is attached to sprockets 76 on both right and left sides.
a, 76b and the interior is constructed.

The transfer chain 75 in the intermediate case 74c
A U-shaped chain receiver 77a having substantially the same length as the intermediate case 74c is mounted on a plurality of chain receiving shafts 77b on the inner side on the return side of a. This chain receiver 77
A chain slide 78 having substantially the same length as the intermediate case 74c is provided on each of the chain receiving shafts 77b at an intermediate portion of the position a in a central portion of the transfer chain 75a at an inner portion on the transfer side. When the grains at the bottom of the intermediate case 74c are transferred by the respective transfer tools 75b, the transfer chain 75a is prevented from floating, and a decrease in the amount of transferred grains is prevented.

Thus, each case 74a, 74b, 7
The transfer amount can be secured without changing the overall height of 4c, and the sprockets 76a and 76b do not need to be large in diameter, so that the driving power does not increase and it is economical.

Claims (1)

[Claims] 1. A plurality of grain storage silos 39 for storing grains, a detection device 43 for detecting a grain height HA in the storage silos 39, and a weight of incoming grain WA. A receiving and weighing machine 7, a grain weighing machine 62 for measuring a moving grain weight WC of grains to be moved after receiving, a grain type manually input at the time of receiving, and a grain moisture value MS detected by the moisture sensor 13a, and weighing. In a grain drying facility provided with display means 10 for displaying the obtained grain weights WA and WC, the detected grain height HA and the stored grain weight WB converted from the grain height HA, etc. When the grains measured by the grain weigher 62 are additionally supplied to the storage silo 39 storing the grains weighed by the grain weigher 62, the additional grain weight WC1 is added to the stored grain weight WC. The detected total grain weight WD is displayed and the detection device 4 The additional grain layer height HA1 up to the added grain detected in step 3 is displayed. Further, when the grains measured by the grain weighing machine 62 are additionally supplied to the storage silo 39 storing the grains not measured by the grain weighing machine 62, only the additional grain weight WC1 is displayed to further display the grain. The grain height measuring device 62 displays the additional grain layer height HA1 up to the added grain detected by the detecting device 43 and the storage silo 39 storing the grain not measured by the grain measuring device 62. When additional grains are not supplied, the additional storage layer height HA1 up to the additional grains detected by the detection device 43 is displayed, and the converted storage grain weight converted from the additional detection of the additional layer height HA1 is further detected. Control device 11 for controlling display of WB1
A grain quantity control device for a grain storage silo, comprising:
