Description

The present invention relates to a cereal co-drying facility (country elevator) for drying, preparing and storing rice and wheat.

[Prior art] In a conventional grain drying facility, paddy and the like that have been roughly selected and weighed in the receiving process are dried and stored in silos, and paddy and the like in the silos are taken out in the selective and sales process. After removing thawed grains and immature grains, weigh again and sell to the government.

[Problems to be solved by the invention]

By the way, in such a grain drying facility, one weighing machine having the same function is installed in each step, even though the operation times of the receiving step and the selection / delivery step are different. Therefore, the equipment area and
Extra costs and transporters are required.

In view of this, it is a technical object of the present invention to effectively operate mechanical equipment in a grain co-drying facility and to reduce equipment costs and electric power.

[Means for solving the problems] In order to achieve the above object, in the grain co-drying facility of the present invention, a receiving step including a receiving hopper and a roughing machine,
In a grain co-drying facility having a screening machine equipped with a screening machine for removing degranulation, a drying process, and a silo, a. In order to perform the weighing in the receiving step and the selecting step with one weighing machine, a flow path connecting them is interposed between the roughing machine and the weighing machine in the receiving step to interpose a selecting machine.

B. A flow path switching device is provided at a branch portion of the flow path.

C. Further, the discharge path of the silo and the flow path switching device are connected.

Taking the technical measures of that.

(Operation)

Grains, for example, paddy stuffed from the receiving hopper are weighed after removing straws, strings, plant chips, dust and the like by a roughing machine, and then temporarily stored in a silo and dried sequentially. The paddy that has been dried to an appropriate amount of moisture is again put into a silo and stored. Then, in the selection step, the paddy in the silo is transferred from the discharge path to the receiving step, and supplied to the selection machine by the flow path switching device. In the selection machine, the deflocculated grains and immature grains are removed, and then the weight of the sized paddy is weighed by the same weighing machine at the time of receipt.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the paddy brought in is transferred from the receiving hopper 1 to the roughing base 3, the weighing machine 8, the silo 28, the dryer 31, and the silo 28. Machine 9, weighing machine 18, and silo 28.

The screening machine 9 has three sorting tubes 11 at the upper stage, three sorting tubes 13 at the middle stage, and two sorting tubes 15 at the lower stage (see FIG. 2). Divide into paddy.
As shown in FIG. 3, the sorting method is as follows. As the sorting cylinders 11, 13, and 15 rotate in the direction of the arrow, the grains having a short length are separated from the sorting cylinder 1.
The troughs 10, 1 fit into the pot holes 16 provided on the inner circumference of 1, 13, 15
It is transported in 2,14 and transported on the skew conveyor 17
The long rice grain is configured to be transported into the sorting cylinders 11, 13, and 15 without being caught by the pot holes 16 and discharged out of the machine.

Next, the operation of the above embodiment will be described. The paddy put into the receiving hopper 1 is passed through the elevator 2
Is supplied to the wind selection unit 5 from an inlet 4 provided in the upper part of the air conditioner. By the rotation of the blower 6, immature paddy, light straw and dust are collected by an exhaust duct 7 into a container provided outside the machine. In this manner, the paddy having been subjected to the wind selection is supplied to the storage tank 22 of the weighing machine 18 through the direct connection transfer path 20 by switching the switching valve 19 in the load receiving step. The paddy in the storage tank 22 is put into the measuring tank 23 by a valve 24 that opens every predetermined time. For example, when 100 kg is weighed, the valve 24 closes, and thereafter, this operation is repeated. The weighed paddy is discharged from the discharge port 25, and is temporarily stored in the silo 28 via the elevator 26 and the supply conveyor 27. The stored paddy is dried from a silo 28 through a discharge conveyor 29 and a lift 30 through a dryer 31.
Transported to The paddy dried to an appropriate amount of moisture in the dryer 31 is returned to the silo 28 via the elevator 32 and the conveyor 27.

At the time of selection and sale, paddy of silo 28 is conveyed.
29, it is conveyed through the discharge path 33, the elevator 30 and the circulation path 34 to the discharge side flow path of the roughing machine 3 in the load receiving process. At this time, by switching the switching valve 19, the paddy is supplied to the equalizer 8 of the screening machine 9 through the transfer path 21. Then, the paddy is divided into three equal parts by the equalizer 8 and sorted by the sorting cylinders 11, 13, and 15, respectively. That is, in the first stage of the sorting cylinder 11,
The flour and the paddy enter into 10, the branch stalks and the paddy remain in the sorting cylinder 11, and those in the receiving trough 10 are supplied to the third-stage sorting cylinder 15. In the second-stage sorting cylinder 13, the first-stage sorting cylinder
The branch stalks and paddy in 11 are sorted, the paddy enters the trough 12, and the branch stalks remain in the sorting cylinder 13. And the paddy is weighing machine 18
And the branch stalks are transported to a container provided outside the machine. In the third-stage sorting cylinder 15, the threshing and paddy in the first-stage receiving trough 10 are sorted out, and the threshing particles enter the receiving trough 14 and are collected in a container provided outside the machine, The paddy remaining in the sorting cylinder 15 is transported to the storage tank 22 of the weighing machine 18. The weighing machine 18 measures the weight of the paddy in the same manner as at the time of receiving the cargo, stores it as a refined product in the silo 28 via the elevator 26 and the conveyor 27, and sells it to the government.

Thus, the refined paddy stored in the silo 28 is discharged from the silo 28 as necessary, and transported to the next step of hulling / shipping step (not shown) via the conveyor 29, the discharge path 33, and the elevator 30. You.

〔The invention's effect〕

As described above, according to the present invention, weighing of grains at the time of receiving goods and weighing of grains at the time of selection can be performed by one weighing machine, equipment costs can be reduced, installation area and power can be reduced. Significant savings can be made.
