Description

[Detailed description of the invention] This invention allows dried grains that tend to remain in the feeding section and the carry-in gutter at the end of drying work to be quickly discharged out of the machine by switching and rotating a single operation lever. This invention relates to a residual grain discharge device in a dryer.

Conventionally, hot air chambers and exhaust ventilation chambers are arranged alternately in the main body of the dryer so that a paddy flow path is vertically arranged between the two chambers, and one end of a grain board is placed at the feeding part at the lower end of each of the paddy flow paths. The grain flow plate is rotated downward by operating the handle, and the lower end of the paddy flow path is made open, so that the grain filled in the dryer body and the paddy flow path can be removed from the lower stage. An opening/closing operation of the opening/closing plate by pivoting one end of the opening/closing plate to the bottom of the loading gutter installed horizontally at the top of the dryer's discharge device and the top of the dryer main body, which drop it into a tank and discharge it outside the machine. The residual grain discharge device in a dryer, which opens the bottom of the inlet gutter and allows the residual grain in the inlet gutter to fall to the bottom, was disclosed in Japanese Utility Model Publication No. 47-9018 prior to this application.
It is described in Japanese Utility Model Publication No. 57-191435 and is well known.

By the way, none of the conventional dryers is equipped with both a discharging device in the feeding section and a discharging device in the carry-in gutter, so all of the dried grains must be completely removed from the machine at the end of the drying process. Some of the grains inevitably remain in the feeding section or in the carry-in gutter, which allows rats to enter, creating unsanitary conditions, or causing drying work due to solidification. There were disadvantages such as making the drying process uneven, and furthermore, different types of grains were mixed in when drying different types of grains.

Therefore, during drying operations, the present invention simultaneously opens the multiple feeding sections and loading troughs where residual grains tend to occur inside the dryer body by switching the left and right operation of a single operating lever. By dropping all the grains at once and efficiently discharging them outside the machine, drying work can be accomplished more hygienically and efficiently, and the structure of the operating mechanism of the dryer can be simplified. The purpose of this invention is to obtain a residual grain discharge device in a dryer that can accurately dry different kinds of grains.

In view of the above, and in order to achieve the above object, the present invention has a structure including a rotating body for supporting a movable flow grain plate which is pivotally connected to a feeding part at the lower end of a plurality of paddy flow channels vertically installed in the dryer main body; The operating lever that opens and closes the opening/closing plate, which is pivoted to the end of the loading gutter installed horizontally on the top of the dryer body, is interlocked with the operating lever that is mounted on a shaft so that it can be switched and rotated in the left and right directions. This is a residual grain discharge device for a dryer characterized in that they are connected to each other, and according to this device, the movable grain plate and the opening/closing plate can be simultaneously operated by switching and rotating a single operation lever in the left and right direction. When the feeding section and the carry-in gutter are closed by opening and closing operations, the grains filled in the dryer body can be accurately circulated and the drying work can be carried out efficiently. In some cases, the feeding section and the loading gutter are opened at the same time, allowing grain remaining in the feeding section and loading gutter to fall all at once.
This can be efficiently discharged outside the machine, and as a result, there is no residual grain inside the dryer, which eliminates the entry of rats and makes drying work sanitary, while at the same time solidifying the residual grain. In addition to preventing the occurrence of corrosion due to adhesion, it also improves the efficiency of discharging grains at the feeding section, and even if the dryer operating mechanism is simple, all dried grains can be discharged outside the machine in a short time. Moreover, even different types of grains can be efficiently dried without being mixed.

The above-mentioned carry-in gutter 17 has an opening 18 in the majority of the portion located at the top of the dryer main body 1, and the portion extending outside the dryer main body 1 is formed in a bottomed shape, and has an appropriate length from the carry-in side. Opening 18 that spans
An opening/closing plate 20 having a substantially L-shaped cross section, whose base end is pivotally connected to the carry-in gutter by a hinge 19, is positioned to open and close the opening.

Reference numeral 21 denotes a carry-in screw mounted on a storage axis within the carry-in gutter 17, and 22 denotes a plurality of carry-in windows opened in the side wall of the carry-in gutter 17 in the portion where the majority of the carry-in gutter 17 is closed by the opening/closing plate 20. .

The movable flow grain plates 9 are respectively pivotally connected to the plurality of feeding parts 11 as described above, and one end of the movable grain plates 9 is directly connected to the shaft 23, and the supporting rotating body 24 is mounted so as to be rotatable in the left and right direction. is supported by the upper end of the carry-in gutter 17.

The link rods 30 . . . all at once assume a substantially erect shape and support the respective movable flow grain plates 9 . . . in a horizontal manner. On the other hand, the operating rod 32 connected to the operating lever 28 is raised by the above-mentioned operation, and the link rod 31
The opening 18 of the carry-in gutter 17 is closed by lifting and supporting the opening/closing plate 20 by a plurality of standing support rods 27 . Next, after the connection window between the carry-in gutter 17 and the discharge tube 33 is closed by the switching plate 34, the feed roll 12, the carry-out screw 15, and the elevator 1 are closed.
6. Operate the carry-in screw 21, the hot air generator 5, and the suction/exhaust fan 13 together. Then, the grains that have been filled in the dryer main body 1 in advance circulate through the dryer main body 1 through the paddy channel 8, the feeding section 11, the take-out tank 4, the carry-in gutter 14, the elevator 16, and the carry-in gutter 17. During this time, the rice is dried to a predetermined moisture content by drying air that flows out from the hot air chamber 6 and flows across the chaff flow path 8 into the exhaust chamber 7.

When the grain drying work is completed in this way, the operation of the hot air generator 5 is stopped, and then the switching plate 34 is rotated to establish communication between the carry-in gutter 17 and the discharge pipe 33, and at the same time, the operating lever 28 is moved forward. Rotate counterclockwise as indicated by the dotted arrow.

, and release the support state of the opening/closing plate 20.
The opening 18 of the carry-in gutter 17 is opened.

Then, all of the dried grains in the carry-in gutter 17 installed horizontally at the top of the dryer main body 1 will fall toward the lower paddy flow path 8... At the same time, the paddy flow path 8...
The dried grains dropped into the take-out tank 4 from the open delivery section 11 are also quickly dropped into the take-out tank 4, and then are discharged outside the machine via the take-out gutter 14, the elevator 16, the carry-in gutter 17, and the discharge tube 33. As expected, feeding part 1
1 and the carry-in gutter 17 can be reliably prevented from generating residual grains. Therefore, all of the dried grains can be completely and efficiently discharged, which not only significantly shortens the drying time but also enables accurate drying of different types of grains. A device for increasing the rotation speed of the rolls 12 is unnecessary, and the structure of the operating mechanism in the dryer can be simplified.
