Description

[Detailed description of the invention] The present invention allows the dry grains thrown by the throwing elevator to be smoothly discharged from the discharge gutter when the shutter housing is switched to the discharge side, and in the process of discharging the dry grains, If the discharge gutter becomes clogged and dried grains overflow into the shutter casing, the overflowing dried grains should not be retained in the shutter casing, but should be immediately returned to the dryer body through the overflow window.
The present invention relates to an overflow device for a paddy dryer that can prevent damage to a throwing elevator and other parts.

First, the present applicant installed a throwing elevator and a discharge gutter on the same side of the upper part of the dryer body so as to communicate with the inside of the dryer body through a throwing window and a discharge window opened with a step. Inside the dryer body in front of the window and discharge window, there is a rotatable shutter housing that makes the throwing window and the discharge window conductive or non-conductive. When the window is left open, grain is carried in or circulated, and when the front side of the throwing window and discharge window is covered with a shutter casing, the dry grain thrown from the throwing window is transferred to the shutter casing. We have developed a device for loading and unloading grain into a dryer that allows grain to be discharged from the discharge window as needed.

By the way, in the case of the above-mentioned device, during the operation of discharging the dried grains to an appropriate place through the discharge window, for some reason the dried grains are not discharged, and the dried grains gradually accumulate and the grains that overflow from the discharge window become shattered. If a situation occurs in which the grains flow into the casing and are deposited, the grain may flow back into the throwing elevator through the throwing window, causing an overload phenomenon that may cause equipment failure and stop operation. When starting up, the grain in the throwing elevator must be removed before it can be operated, which has the disadvantage of requiring a lot of labor and time.

In view of the above, the present invention is a work in which the throwing window and the discharge window are made electrically conductive by the shutter housing, and the dried grains thrown from the throwing window are discharged to an appropriate location from the discharge window through the shutter housing. If, for some reason, the dried grains are not discharged smoothly and overflow into the shutter housing, the overflowing dried grains should be removed from the shutter housing located in front of the discharge window. This allows the flow to flow back into the dryer body more quickly than the overflow window that opens on the side, thereby eliminating the phenomenon of dried grains flowing back from the throwing window to the throwing elevator, thereby preventing damage to the throwing elevator and other parts. The purpose of this invention is to provide an overflow device for a paddy dryer that can prevent this from occurring, and the configuration of the device of the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes a dryer main body that can dry the grain to a predetermined moisture content by blowing drying air on the grain during the process of vertically flowing the grain, and a throwing elevator is installed on the same side of the upper part of the dryer main body 1. 2 and a discharge gutter 3 are installed so as to communicate with the inside of the dryer main body 1 via a throwing window 4 and a discharge window 5 which are opened with a step. A shutter housing 6 rotatably mounted on a support shaft 7 is disposed inside the dryer main body 1 at a position in front of the throwing window 4 and the discharge window 5. By rotating the rotating handle 8 attached to the end, the throwing window 4 is opened.
When the shutter housing 6 is rotated so as to cover the front side of the ejection window 5, the shutter housing 6 becomes a conductive member, bringing the throwing window 4 and the ejection window 5 into a conductive state, and the shutter housing 6 is rotated to cover the front side of the ejection window 5. When the window 4 and the ejection window 5 are turned away from the front side and opened, the throwing window 4 and the ejection window 5 are brought into a non-conducting state. Therefore,
The shutter housing 6 for performing the above-mentioned function has the throwing window 4 and the ejection window 5 side open, and also has the throwing position a.
The bottom wall 6 slopes downward toward the discharge position b.
It is formed into a housing with one side open.
An overflow window 9 having a substantially rectangular shape is provided on the wall plate 6b of the shutter housing 6 at a position corresponding to the front side of the discharge window 5.
is installed vertically.

In addition, a side guide wall 10 and an upper guide wall 11 extending obliquely toward the discharge window 5 side are provided on the opening side edge and the opening upper edge of the overflow window 8 facing the throwing window 4 side, respectively. Even during the discharge operation in which the dried grains thrown by the elevator 2 are guided by the shutter housing 6 and discharged from the discharge window 5 to the discharge gutter 3, the dried grains accidentally overflow from the overflow window 9 into the dryer main body 1. This prevents water from flowing back into the air, and allows dry grain to be smoothly guided and discharged. 12 is a restoring bullet with a rotating handle 8. The lower end of the discharge gutter 3 is usually connected to a hopper of a hulling adjustment processing machine or the like.

Next, the operation of the present invention will be explained.

Now, when drying the grains, put the grains into the dryer body 1.
To transport the shutter into the container, the shutter housing 6 is rotated by rotating the rotary handle 8 to a position where the throwing window 4 and the ejection window 5 are in a non-conducting state, and the front surfaces of the throwing window 4 and the ejection window 5 are opened. state. Then, when the throwing elevator 2 is operated and the grains are lifted, the lifted grains are carried into the dryer main body 1 through the throwing window 4 and filled in a diffused manner by the throwing action. When a predetermined amount of grain is filled, the loading operation is stopped, and the drying air is efficiently circulated while the filled grain is circulated between the dryer main body 1 and the throwing elevator 2 several times. It is then dried to a predetermined moisture content.

Once the grain has been dried in the manner described above, the rotary handle 8 is operated again to rotate the shutter housing 6 about the support shaft 7 so that the throwing window 4 and the discharge window 5 are brought into electrical continuity. Then, the dried grains in the dryer main body 1 are lifted by the throwing elevator 2 and then passed from the throwing window 4 through the shutter housing 6 to the discharge window 5.
and is discharged out of the machine from the discharge gutter 3.

By the way, when performing such dry grain discharge work by guiding the shutter housing 6, the wall plate 6b of the shutter housing 6 located on the front side of the discharge window 5
Even if the overflow window 9 is always open, there are side guide walls 10 on the opening side edge and the opening upper edge of the overflow window 9 facing the throwing window 4 side, which extend obliquely toward the discharge window 5 side.
and an upper guide wall 11 are provided, respectively, so that dry grains flowing inside the shutter housing 6 from the throwing window 4 toward the discharge window 5 are smoothly guided to the side guide wall 10 and the upper guide wall 11, It is discharged outside the machine from the discharge gutter 3 without being discharged from the overflow window 9.

Furthermore, during the above-mentioned dry grain discharge operation, if the discharge gutter 3 is filled with dry grains for some reason, and the overflowing dry grains gradually fill the shutter casing 6, the overflowing dry grains The water flows back into the dryer main body 1 more quickly than the overflow window 9 which is always open, and prevents the water from flowing back to the throwing elevator 2 side. Therefore, even if the operation of the throwing elevator 2 is continued, the grain lifting work can be carried out without overloading the throwing elevator 12 due to overflowing dried grains, so that the throwing elevator 2 and other parts are not damaged. There is no need to worry about it. If the overflow phenomenon is resolved, the dried grains will be discharged outside the machine via the discharge gutter 3 again.

In short, the present invention has the above-mentioned specific configuration, so the shutter housing 6 can be connected to the throwing window 4.
When the rotation is adjusted so that the discharge window 5 is in a non-conducting state, the grain is smoothly transported into the dryer main body 1 in a powdered state via the throwing elevator 2, or the grain is not transported into the dryer main body 1. The grain can be circulated between the dryer main body 1 and the throwing elevator 2, and the drying work can be easily accomplished. When the conductive state is established, the dry grain can be caused to flow from the throwing window 4 to the discharge window 5 by the guiding action of the shutter housing 6, and can be discharged to the outside of the machine. Occasionally, the discharge gutter 3 becomes clogged for some reason, and the shutter casing 6 is leaked from the discharge window 5.
Even if an overflow situation occurs, the overflowing dried grains will not flow back to the throwing elevator 2 side, but will flow through the overflow window 9, which is always open in the shutter housing 6 in front of the discharge window 5, to the dryer main body. Not only does this prevent overload from occurring on the throwing elevator 2, thereby preventing damage to the throwing elevator 2 and other components, but also allows the overflow window 9 to be kept open at all times. Also, a side guide wall 10 and an upper guide wall 11 are provided on the opening side edge and the opening upper edge of the overflow window 9 facing the throwing window 3 side, so that the side guide wall 10 extends obliquely toward the discharge window 5 side, and the upper guide wall 11 is provided. During the dry grain discharge operation, the dry grain flowing inside the shutter housing 6 is transported by the side guide wall 10.
The flow is guided by the upper guide wall 11 to the discharge window 5 side, and is prevented from accidentally flowing back into the dryer main body 1 through the overflow window 9, making it possible to accurately achieve smooth discharge work. be effective.
