Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain dryer that is equipped with a diffusion rotor in the upper part of a storage chamber for diffusing material to be dried.

In a conventional grain dryer, for example, a diffusion rotor is installed below the discharge port of a conveying gutter located above the storage chamber, and the material to be dried discharged from the publication outlet is evenly distributed within the storage chamber by centrifugal force. There is a 48-piece structure designed to spread and supply evenly.

However, due to various factors such as the type of material to be dried, degree of dryness, color supplied, etc., the material to be dried becomes unevenly spread, resulting in uneven distribution of material to be dried within the storage chamber. For this reason, there were problems such as the amount of grain loaded in the storage chamber being restricted and the flow of grain becoming unstable.

This invention was devised in view of the above-mentioned problems, and its purpose is to ensure a sufficient amount of grains to fall into the storage chamber and to ensure smooth flow of grains. The present invention provides a grain dryer.

In order to achieve the above objects, the present invention provides a storage chamber 1 in which dry and repealed grains are not temporarily stored, and a storage chamber 1 in which the received grains are stored.

Next, the operation of the above embodiment will be explained.

The grains supplied to the staking hopper 35 are transported to the elevator 3.

The liquid is sent to the upper center of the screen and discharged from the discharge port 4. This JJI output [13 to 4Ul of grains is motor 2
The particles fall onto a diffusion rotor 2 which is driven to rotate at 1, are scattered by the centrifugal force of the diffusion rotor 2, and are dispersed into the storage chamber 1.

The grains stored in the storage chamber 1 are slowly discharged from the hopper-shaped portion 25 through the drying chamber 23 into the storage chamber 26 by the rotary valve 32.

Then, while the grains are passing through the drying chamber 23, the hot air generated by the burner 29 passes from the hot air chamber 28 through the ventilation frame 24 and between the grains in the drying chamber 23 to dry the grains. , further, the air-discharged seedlings 30 pass through the ventilation frame 24.
and is discharged to the outside by the suction fan 31. The grains flowing down into the grain harvesting chamber 26 by the hot air are transported by 1fFJ by the lower transfer spiral 27, transported upward to the elevator 33, and further transported by the upper transfer device 7. It is discharged from the discharged ml 3 to 11, is 1iii;

The sea urchin grains are dried sequentially while being circulated, but depending on the type of grains, drying claws, supply amount, etc., the diffusion of the grains by the diffusion rotor 2 becomes uneven, and the grains are dried in the storage chamber 1. The proportion of grains that are separated into grains will be unequal.

Now, if the grains are distributed toward the front side in flj' storage chamber 1, for example, as shown in FIG. 1, the level switch Stl, 5W- of the front level switch circuit F is

The voltage that flows through the resistor R-2 increases with respect to the current that flows through the level switch circuit B on the rear side. That is, the voltage between level switch circuit F and level switch circuit B is F
>B, the comparator CP-2 outputs an output, and this output excites the relay coil C[3, which closes the relay contact Cb, causing the motor 11 to rotate in the reverse direction and transmit the current through the vertical link 13 and parallel link 14. telescopic ti
ffl 8 moves forward (to the left in FIGS. 1 and 4) along the transfer tm7a, and the grains discharged from the discharge port 3 are moved forward (leftward in FIGS. 1 and 4 to the left side). In other words, the grains that have fallen from the discharge port 3 to the front position of the dispersing rotor 2 are lost to the rear side of the storage chamber 1 (to the right in Figs. 1 and 4) due to the centrifugal force. be done.

Furthermore, when the granules are distributed toward the rear side of the reservoir 1 (right side in Figures 1 and 4), the voltage between the level switch circuit B and the level switch circuit B becomes FI8, and the voltage between the level switch circuit B and the level switch circuit B becomes FI8, Output η from CP-1. Relay coil CF is excited by this output, and its relay contact C [ closes, causing motor 11 to rotate forward and vertical link 1

The grains that move in the tangential direction (J3 in FIG. 1 and the right side in FIG. and the right side in FIG. 4) until it falls.

When the grains fall from the discharge port 3 to the rear side of the dispersing rotor 2, they are moved to the front side (the left side in Figs. 1 and 4) of the storage chamber 1 due to the centrifugal force. be scattered.

Furthermore, the grains are scattered to the left in the storage chamber 1, for example, as shown in FIG.
Level switch 5W- of the level switch circuit on the l side
5, 3W-6 and the level switches 5W-5- and 7)' of the level switch circuit R on the right side are separated by the pressing force of grain $D. Then, the left level switch circuit has a resistor R-5. R-6. Level switch 5W-7, 5W-
By route 8? R flow I] 1st flow 7t, resistance t< -5- in the level switch circuit R on the right side.

Current flows through the path of level switches 5W-6+5W-7- and 5W-8-. Therefore, the current flowing through the level switch circuit on the left (I!lI) is 11jll on the right (7)
For the current flowing through the level switch circuit R, U 11 or 4
ii The voltage increases by the amount flowing through R-6. That is, since the voltage between the level switch circuit [and the level switch circuit R becomes 1->R, an output is output from the comparator 4, and this output excites the relay coil CR, so that the relay contact C1 Since the motor 17 rotates in the opposite direction, one parallel link (1) and the swinging gutter 9
The grains rotated to the left (to the left in Fig. 3, upward in Fig. 4) and are discharged from the discharge port 3h\ to the center of rotation of the dispersing rotor 2. Left side (left side 7th 4th in Figure 3)
It is swung to the position where it falls (upper side in the figure). Then,
The grains falling from the discharge port 3 to the left side of the dispersing rotor 2 are scattered to the right side (right side in Figure 3, lower side in Figure 4) by the centrifugal force. Ru.

Furthermore, when the grains are distributed to the right side in the storage chamber 1 (the right side in Fig. 3, the lower side in Fig. 4), the level switch circuit 1 and the level switch circuit R The voltage becomes L<R and is output from the comparator Cl) -3. This output excites relay coil CL,
Since the relay contact C closes, the motor 17 rotates in the forward direction, and the first moving gutter 9 rotates to the right (to the right in Figure 3, to the bottom in Figure 4) around the support bin 10 via the parallel link 19. The grains that move and are discharged from the discharge port 3 are on the right side with respect to the center of rotation of the diffusion rotor 2 (right side in Figure 3, lower side in Figure 4).
It is swung to the position where it will fall. Then, the grains that have fallen from the discharge port 3 to the right side of the diffusion rotor 2 are moved to the left side (left side in Figure 3, upper side in Figure 4) due to the centrifugal force.
Dispersed widely.

As mentioned above, the position of the outlet 3 for discharging grains onto the spreading rotor 2 is controlled, but the telescopic 6m8 and the swinging shelf 9 operate simultaneously, so that, for example, the telescopic side 8 In some cases, the swing shelf 9 is shortened forward and sideways and rotated to the left.

J3, expandable! iii+8 moving type in the front and back direction,
The amount of rotation of the swing shelf 9 in the left-right direction is controlled by a limit switch (not shown) or the like.

As mentioned above, according to the combination of the present invention, the grains supplied from the discharge port onto the spreading rotor are spread and distributed in the storage chamber, causing uneven distribution in the storage chamber. If so, the detection device detects this, and the supply position adjustment device controls the supply device at the discharge port so as to eliminate the unevenness of the grains to be dispensed. Therefore, it is possible to correct the unbalanced distribution of the packed grains in the storage chamber, prevent a decrease in the amount of packed grains, and also ensure a smooth flow of grains in the storage chamber. Is possible.

It should be noted that the present invention is not limited to the above-described embodiments, and the present invention can be practiced in other forms than the above-described embodiments.
