Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a combined drying and storage device for grains, and this type of combined drying and storage device for grains is capable of handling raw grains with a high moisture content of 20% or more harvested with a combine harvester or the like. The grain is stored and dried, and the drying process is completed until the moisture content reaches about 15 cm.However, in drying grains with high moisture content, even if the temperature is raised and the grain is dried with hot air, cracks will occur. However, if the moisture content of the grain falls below a certain level by continuing the drying process and the moisture content of the grain falls below a certain level, the incidence of split grains will suddenly increase, resulting in a decline in the quality of the grain.

Accordingly, the present invention provides a detection section of an automatic moisture meter equipped with a relay contact mechanism that operates according to a set moisture content on the inner wall of the tank near the porous wall floor of the tank, and a detection section formed in the tank. The moisture content of the grain is measured at the bottom of the stored grain layer, and when the measured moisture value reaches the set moisture content, it is immediately drained and rotated (replacement of paddy) in a replacement tank, and the stored grain is The purpose of the present invention is to develop and provide a convenient device that eliminates the rise in grain temperature and the resulting imbalance in moisture distribution, thereby completely preventing the occurrence of split grains and heat-damaged grains.

Hereinafter, the present invention will be explained with reference to embodiment figures.

In FIGS. 1 and 2, reference numeral 1 in the figures is a dry storage tank, and a plurality of tanks are arranged in parallel and in tandem, and an elevator 2 is erected on one side of the tank. Each tank

Since this conveyor 16 is configured to freely rotate forward and reverse, the grains are transferred to any fixed conveyor 3 provided on the carrying conveyors 5, 5 installed in parallel at the upper part of each tank, and The moving conveyor 4 is also configured to be able to freely rotate forward and backward and move laterally in the front and rear directions, so that the grains can be conveyed to the upper part of any tank via the moving conveyor 4 and put therein for storage. .

Next, in the process of carrying out the stored grains, the air outlet 12 of the ventilation chamber 9 of the tank 1 to be carried out is closed by operating the automatic opening/closing shutter 13, and the outlet ports 10 on both sides of the porous wall and floor part 8 are closed.
．． The automatic opening/closing shutter 14.11 provided at 10 is activated to open, rotate the lower unloading conveyor 6 and elevator 2, and operate the switching valve 25 of the upper discharge part to open the flow path for the unloading. When communicated with the relay conveyor 16 of the process or the discharge gutter 11, the grain in the tank naturally flows down to its angle of repose and flows out from each outlet 10. is opened, and the remaining grains are blown by the inclined blast holes 11 of the porous wall floor part 8, and the remaining grains are transported by flight and flowed out from the take-out port 10, and further passed through the conveyor 6 for carrying out and the elevator 2. It is discharged to the relay conveyor 16 in the carry-in process or to the discharge gutter 17 in the discharge process.

Next, the automatic moisture meter 18 and rotation control circuit 19 will be explained.

As shown in FIG. 4, the moisture meter 18 consists of a container body part 20 and a detection part 21, and the moisture content detected by the detection part 21 and the arbitrary set moisture content (approximately 15%) set in the moisture setting circuit 22. A contact of a relay contact mechanism 55 is activated by a signal generated by comparing the . At the same time, the relay contact mechanism 55 is connected to the control circuit 19 for the rotation conveyance process.

Next, the control circuit shown in FIG. 5 will be explained.

When the detecting section 21 of the automatic moisture meter 18 detects moisture in the grain in the grain tank, a corresponding signal is sequentially transmitted by the transmitting circuit 51, and after further detection by the detecting circuit 52, the signal is sent to the comparing circuit 53. A separate water setting circuit 22 is connected to the
The moisture content is set to an arbitrary setting (around 15 coefficients), and each signal inputted to the comparison circuit 53 is compared.The comparison signal is amplified by the amplifier circuit 54, and also enters the relay contact mechanism 55 to activate the relay contact. Opens and closes.

This output signal activates the alarm 56 on the one hand, and is introduced into the control circuit 19 of the rotation conveyance process on the other hand to each circuit 57, 58, 60, 61, 6.

This is a stop position indicating circuit for stopping at a certain position.

In addition, each detection section 21... may be branched from one vessel body section 20, and when output signals are emitted from multiple tanks at the same time, the ventilation of the tanks other than those to be rotated should be stopped, and the appropriate It would be advantageous to provide a control device to perform the rotation sequentially at intervals of a certain amount of time.

With the above-mentioned configuration, the harvested fresh and dead products with high moisture content are stored in each tank other than the arbitrary replacement tank 1a, and the hot air generated by another hot air generator 7 is stored. The grains in each tank are dried by blowing air into the desired tank.

Further, an automatic moisture meter 18 is disposed in each tank, and an arbitrary predetermined moisture content is set in the moisture setting circuit 22 thereof.

The moisture content set at this time is the moisture content at which the occurrence of shell cracking increases.

However, the moisture content of grains varies depending on their condition, but it is usually 15%.

The detection unit 21 of the moisture meter 18 detects the moisture content of grains in the tank inner wall 23 near the porous wall and floor 8, and compares it with the set moisture content in a comparison circuit 53. Based on the signal, a relay contact mechanism 55 When the signal is transmitted in any tank 1, the signal immediately activates the alarm 56, and each circuit 57, 58 provided in the rotation control circuit 19 .60

When the starting circuits 60 and 61 are activated, the carry-out conveyor 6 and the elevator 2 are driven, and the grains on the conveyor 6 are lifted to the upper side of the elevator 2 and flow down to the relay conveyor 16.

When the starting circuit 62 is started, the relay conveyor 16 and the carry-in conveyor 5 each rotate, and the moving conveyor 4 at the end of the moving conveyor 4 starts a stop position indicating circuit 64 by a signal from a detection device 63 such as an empty level meter. It stops at the input position of the replacement tank 1a, and the grains to be transported are sequentially transferred to the tank 1a.
The rotation will be carried out in the future.
