Description

[Detailed description of the invention] Industrial application field This invention is designed to solve the problem that when the dry grains thrown from the throwing port are fed from the discharge gutter to the adjustment processing machine in the next process, the discharge gutter It became full,
If dried grains overflow from the discharge gutter to the front side of the dryer, the overflowing grains will be caught and the front side of the throwing port will be opened due to the weight load, and the dried grains will be returned into the dryer body. The present invention relates to a grain take-out device in a throwing-type grain dryer that prevents dried grains from being piled up above a required height on the front side of the dryer main body.

Conventional technology Conventionally, when the throwing port of a throwing type elevator was opened using a switching valve, the grain was thrown into the main body of the dryer by a throwing action to perform drying work, and when the front side of the throwing port was shielded using a switching valve. A grain dryer that supplies dried grains to a working machine for the next process through a discharge gutter is known and was described in, for example, Japanese Utility Model Application Publication No. 58-87730 before the present application. explain. That is, the dryer main body 1 and the throwing elevator 2 are connected through the throwing port 3, and the discharge gutter 4 is placed in an open position between the dryer main body 1 and the throwing elevator 2, and the front side of the throwing port 3 is connected. At this position, a switching valve 5 for shielding the front side of the throwing port 3 or opening and closing the discharge gutter 4 is mounted on a shaft so that it can be slidably adjusted in the vertical direction.

Problems that the invention aims to solve By the way, in conventional grain dryers of this type, when the front side of the throwing port was shielded by a switching valve and the dry grain was supplied to the working machine for the next process through the discharge gutter, If the amount of dry grain supplied is greater than the processing capacity of the working machine in the next process, or if the working machine in the next process stops for some reason, the discharge gutter will immediately become full. The disadvantage is that the dried grains overflow, pile up in a heap at the top of the discharge trough, and eventually flow back into the throwing elevator through the throwing opening, causing damage to the throwing elevator.

Means for solving the problems The present invention solves the above problems, and includes:
The contents will be explained with reference to FIGS. 1 and 2.
That is, the throwing type elevator 102 and the dryer main body 10
1 through a throwing port 103 opened at the top of the throwing elevator 102. Inside the dryer main body 101 in front of the above-mentioned throwing port 103, three faces, front face 106a, rear face 106b, and bottom face 106c, are open, and discharge is discharged to the front bottom side extending from the dryer main body 101 toward the throwing type elevator 102 side. A grain distribution case 106 to which a gutter 107 is open-connected is detachably attached.

Rotating shaft 108 mounted inside the grain distribution case 106
A pair of mounting rods 109, 109 are fixed to. The distal ends of the pair of mounting rods 109, 109 can be slid up and down about the rotating shaft 108 to cover the front side of the throwing opening 105 or to form a discharge gutter 107.
A discharge switching valve 110 is installed to open and close the valve.

The pair of mounting rods 109, 109 described above are equipped with return grain receivers 111 for receiving overflowing grains from the discharge gutter 107.

Function Now, when it is desired to dry the grain by throwing it into the dryer body 101 in a substantially level state by the throwing operation of the throwing elevator 102, first, the discharge switching valve 110 is turned on by the rotational movement of the rotating shaft 108. After descending and closing the discharge gutter 107, the grain is fed into the throwing elevator 102. Then, the grain will be transferred to the throwing elevator 1.
After the grain is fried by 02, it is thrown from the throwing port 105 toward the grain distribution case 106.

Therefore, the upper half of the thrown grain enters the grain distribution case 106 through the front opening 106a, exits through the rear opening 106b, and is carried into the dryer main body 101 located further away from the throwing elevator 102. At the same time, the thrown grain in the lower half enters from the front opening part 106a, comes out from the bottom opening part 106c, is received by the return grain receiver 111 located in a substantially hanging state, and falls into the dryer main body 101 on the throwing type elevator 102 side. be done. Therefore, if the grain throwing operation as described above is continued for a while, a predetermined amount of grain is filled into the dryer main body 101 in a substantially even state.

As described above, a predetermined amount of grain is added to the dryer body 1.
01, the supply is stopped, and the filled grains are made to circulate and flow inside the dryer main body 101 by the same throwing operation as described above, and at the same time, the circulating and flowing grains are dried by being exposed to dry hot air, and are dried to a predetermined moisture content. The drying process is completed by obtaining a certain amount of dry grain.

Next, when it is desired to supply the dried grains to the working machine for the next process through the discharge gutter 107, the rotary shaft 108
is activated to move the discharge switching valve 110 upward about the rotating shaft 108 to shield the front side of the throwing port 105 and open the discharge gutter 107, and furthermore, the blowing of dry hot air is stopped. Under this condition, dried grains are thrown by a throwing elevator 102 from a throwing opening 105 toward a discharge switching valve 110. Then, all of the thrown dry grains are received by the discharge switching valve 110, fall into the discharge gutter 107 under the guidance of the valve, and are successively supplied to the working machine (not shown) for the next process. By the way, the discharge gutter 107
If the amount supplied to the next process is greater than the processing capacity of the work equipment in the next process, or if the work equipment in the next process stops for some reason, the discharge gutter 107 will immediately become full and the water will be discharged from the upper end of the discharge gutter 107. Dried grains overflow to the front side of the dryer main body 101 and are deposited in a heap.
Eventually, the water will flow back into the throwing type elevator 102 from the throwing port 105.

However, in the present invention, the pair of mounting rods 109, 109 equipped with the discharge switching valve 110 are equipped with a return grain receiver 1 for receiving the overflowing dried grains.
11 is installed, the dried grains overflowing from the discharge gutter 107 to the front side of the dryer main body 101 are received by the return grain receiver 111.

When a certain amount of overflowing dry grain is received on the return grain receiver 111, the discharge switching valve 110 is slid downward about the rotating shaft 108 due to the weight load action, and opens the front side of the throwing port 105. . As a result, the dried grains thrown from the throwing port 105 pass through the grain distribution casing 106 without being received by the discharge switching valve 110 and are dumped into the dryer main body 1.
It is carried into 01.

Therefore, the thrown dry grains are discharged into the discharge gutter 10.
Since the dried grains are not supplied to the side 7, no more dried grains are overflowed to the front side of the dryer main body 101, and the dried grains filled in the discharge gutter 107 are supplied to the working machine of the next process for processing. and discharge gutter 1
When the dried grains in the drain hole 107 are exhausted, the front side of the throwing port 105 may be blocked again by the discharge switching valve 110 to supply the dried grains to the discharge gutter 107.

Embodiment The configuration of the grain take-out device in the throwing type grain dryer according to the present invention will be described with reference to a preferred embodiment shown in the accompanying drawings.

In the drawings, reference numeral 101 denotes a dryer main body that can dry the carried grain by exposing it to dry hot air while it is being flowed down.
A throwing elevator 102, which is constructed by rotatably encircling a belt 103 having a large number of buckets 104 for throwing, is attached to one side of the elevator 1 at intervals. The dryer main body 101 and the throwing type elevator 102 are connected through a throwing port 105 opened at the top of the throwing type elevator 102.

A grain distribution case 106 is removably installed inside the dryer main body 101 on the front side of the throwing port 105.
The grain rationing case 106 has three open sides as a whole: a front side 106a, a rear side 106b, and a bottom side 106c.Moreover, the bottom side of the front part extending from the dryer main body 101 toward the throwing type elevator 102 has a lower end. The upper end of the discharge gutter 107 connected to a working machine (not shown) for the next process is opened and installed. Therefore, the front opening 106a of the grain distribution case 106 communicates with the throwing port 105.

A rotating shaft 10 is located at the rear of the grain distribution case 106.
8 is mounted on a shaft so that it can rotate left and right, and this rotating shaft 108 has a pair of left and right mounting rods 109, 10.
9 is fixed thereto, and a discharge switching valve 110 is provided on the distal end side of the pair of left and right mounting rods 109, 109 in an inclined shape, which can shield the front side of the throwing port 105 or open and close the discharge gutter 107. is installed on. 111 is a pair of mounting rods 109,1
09, the base end side of which is attached to the lower end of downward-facing support rods 112, 112. Furthermore, an adjustable adjustment plate 113 is attached to the lower part of the return grain receiver 111 by a tensioning tool 114 and extends forward from the lower front side. Therefore,
When the adjustment plate 113 is extended longer than the front lower side of the return grain receiver 111, the distance between it and the front wall 101a of the dryer main body 101 is narrowed so that overflow from the discharge gutter 107 into the dryer main body 101 is reduced. It can receive a lot of returned grain.

Note that when the discharge gutter 107 is completely closed by the discharge switching plate 110, the return grain receiver 111 is in a substantially vertical state, and is inserted into the dryer main body 101 through the grain distribution casing 106 from the throwing port 105. catch some of the grains thrown at the dryer body 101 and guide the grains to fall toward the front wall 101a side of the dryer main body 101;
Promote level distribution of grains.

115 is an operating rod for vertically sliding the discharge switching valve 110, and a long hole 116 provided at one end of the operating rod 115 is directly connected to the other end of an operating arm 117, one end of which is directly connected to the rotating shaft 108. 118
The other end of the operating rod 115 is pivotally connected to a piece of an L-shaped operating body 118 rotatably mounted on the side wall of the throwing elevator 102. An operating lever 119 that can be pushed or pulled is pivotally attached to the other part of the L-shaped operating body 118.
The discharge switching valve 11 is opened by pushing and pulling the operating lever 119.
0 is caused to slide vertically about the rotating shaft 108.

Reference numeral 120 denotes a towing bomb whose one end is attached to a proper position of the grain distribution case 106 and the other end is attached to the other end of the lowering arm 117, and the operating arm 117 is moved by the biasing elasticity of the towing bomb 120. The discharge switching valve 110 is connected to the throwing port 1.
05 is towed in the direction of shielding.

Effects of the Invention In short, the present invention has the technical means described above, so that when the discharge gutter 107 is closed by the discharge switching valve 110 that is slidable about the rotating shaft 108, the throwing port 105 of the throwing elevator 102 is closed. A part of the grain thrown by the grain distribution case 106 is passed through the front open part 106a and the rear open part 106b into the dryer body 101 that is far from the throwing elevator 102, and other grains are passed through the front open part 106a and the bottom part. The throwing type elevator 10 is thrown through the opening part 106c toward the return grain receiver 111 which is in a substantially vertical shape, and the receiving action of the return grain receiver 111 causes the throwing type elevator 10 to be thrown.
The grains are continuously carried into the main body 101 of the dryer on the second side, and all of the thrown grains are distributed accurately and approximately evenly without having to adjust the discharge switching valve 110 or the return grain receiver 111 one by one. It is possible to perform a good drying operation, and when it is desired to supply the dried grains from the discharge gutter 107 to the next process upon completion of the drying operation, a simple method is adopted in which the front side of the throwing port 105 is blocked by the discharge switching valve 110. This can be easily achieved by operation, and when discharging dry grains, the discharge gutter 107 may be
Dry grains overflowing from the upper end of the dryer body 101
Even if the dried grains are dropped to the front side of the dryer body 101 and gradually piled up in a pile, the dried grains that are about to fall to the front side of the dryer main body 101 are returned to the grain receiver 11.
2, and the weight load action automatically causes the discharge switching valve 110 to slide in the direction in which the front side of the throwing port 105 opens, allowing the dried grains to flow back into the dryer main body 101, significantly reducing the amount of supply to the discharge gutter 107. Dry grains decreased and overflowed into the throwing port 10.
This has the effect of preventing an accident in which the water is returned to the throwing elevator 102 from 5 and causes a malfunction.
