Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in grain storage tank systems.

Even if raw paddy rice is of the same variety that is received by a receiving facility such as a country elevator, the grain moisture value often differs from farm to farm and from cargo to cargo, and if they are accumulated in the same storage tank in the order in which they are received, In the drying process in the post-process, drying spots may occur, which may significantly reduce the quality of stored paddy rice.

In order to solve the above-mentioned drawbacks, the present invention measures the moisture content of the received raw material paddy rice at the supply hopper of the elevator or at the receiving process connected to the hopper, and uses the measurement signal to measure the moisture content of the raw paddy rice. By selecting the on-off valves at appropriate positions from among the on-off valves on the transport conveyor suspended horizontally on the upper part of the container and opening and closing them in a related manner, unhulled rice with the same measured moisture content is automatically transferred to the same storage tank. At the same time, we aim to develop and provide a high-performance and high-efficiency device that stores raw paddy rice in several stages according to its moisture content.

To explain the present invention with reference to an embodiment diagram, a large number of grain storage tanks 1A, 1B, 1C, etc. are arranged side by side, and an elevator 2 installed upright on one side and each of the storage tanks 1A, 1B, Conveyor 3 consisting of a screw conveyor etc. suspended horizontally on the upper part of 1C... is interconnected to form an integrated grain storage tank device, and the unhulled rice of each farmer received by the receiving mechanism of the device is At the same time, the unhulled rice is fed into the lower supply hopper 4 of the elevator 2 and sent to each storage tank 1A, 1B, 1C via the elevator 2 and the conveyor 3.
The grains are fried and transported to... and stored separately.

The lower supply hopper 4 of the elevator 2 is provided with a moisture measuring device 5 in the hopper 4 or in the cargo receiving process connected to the hopper, and a regulator having an electric circuit for the measuring device 5 mounted on the wall of the elevator 2. 6, and at the bottom of the screw conveyor gutter of the conveyor 3, each grain storage tank 1A,
Grain discharge ports 7A, 7B, 7C for discharging grains are opened for each of 1B, 1C, and each opening is provided with on-off valves 8A, 8 operated by a solenoid.
B, 8C... are provided respectively, and each on-off valve 8A, 8
Electric circuits B, 8C, . . . are connected to the regulator 6, respectively.

Next, the regulator 6 has several types of grain moisture content (20%
A regulator 9 is provided, which consists of several sets of classification switches each activated by a maximum of 21%...24%) and several sets of timers connected to the regulator 9, and the input side of the regulator 9 is connected to the moisture measuring device. 5, and the output sides thereof are respectively connected to the solenoids of the on-off valves 8A, 8B, 8C..., and the on-off valves 8A, 8 operate in accordance with each moisture value measured by the moisture measuring device 5.
B, 8C, . . . are suitably selected and operated to fry and supply paddy grains with the same moisture content to the same storage tank, respectively.

With the above-described configuration, raw paddy rice is fed into the lower supply hopper 4 of the elevator 2 through the receiving process,
In addition, several classification switches built into the regulator 6 are set to various levels of arbitrary moisture content (20% to 24%), and when the device is started, the moisture content of the input unhulled rice is adjusted. The moisture meter 5 measures the moisture content, and the measurement signal operates a suitable sorting switch provided in the regulator 6, and the unhulled rice is fried by the elevator 2 and flows into the upper conveyor 3. Suppose that in the regulator 6, the classification switch which is set to a moisture content of 20% is connected to the on-off valve 8A, and the moisture content is set to 24%.
When the classification switches set with % are respectively connected to the on-off valves 8E, for rice grains whose moisture content is measured at 24% in the supply hopper 4, the measurement signal is transmitted via the timer to the on-off valve 8E of the conveyor 3. is operated to open the grain discharging port 7 of the conveyor 3.
E is discharged downstream and stored in storage tank 1E. In addition, the rice grains with a moisture content of 20% measured in the supply hopper 4 are discharged down from the grain discharging port 7A of the conveyor 3 and stored in the storage tank 1A. The rice grains are fed down to the same storage tank and stored.

In this way, the grain storage tank device of the present invention
The moisture content of the raw paddy rice is measured in the supply hopper of the elevator or in the receiving process connected to the hopper, and the measurement signal is used to control the appropriate opening/closing valves of the transport conveyor suspended above the multiple storage tanks. Since the opening/closing valves are set to open and close, the unhulled rice with the same moisture content is always stored in the same storage tank, completely preventing the occurrence of dry spots due to the drying operation in the post-process mentioned above. The structure is extremely simple and easy to install on conventional equipment, and it is possible to complete the automation of divided storage according to several types of grain moisture content, achieve labor savings, and ensure the mass production of high-quality stored grains. It is effective.
