Description

[Detailed description of the invention] This invention enables the paddy to be quickly transported into the dryer main body with labor savings by simply pulling out and pushing in the lid that also serves as a supply stand. The present invention relates to a suction-type paddy drying device that can reliably prevent outside air from entering into a take-out tank through a supply port of a loading hopper, thereby allowing smooth suction drying work.

Conventionally, in order to carry a predetermined amount of paddy into the main body of the dryer, the loading operation was carried out via a hopper attached to an elevator installed upright at the rear of the main body of the dryer.

Therefore, when carrying in paddy, the worker must go through a narrow passage to the back of the dryer body and repeatedly feed the paddy into the hopper, which requires a lot of effort and time. This was extremely inconvenient, and there was a strong desire for improvement.

In view of the above, the present invention has been developed by installing a tensioning hopper and a suction blower so as to face each other on the front and rear walls of a take-out tank located at the lowest part of the dryer body, so that the rice can be stretched at the front of the dryer body. In addition to making the loading work easier, a lid with legs that also serves as a supply table is attached to the supply port of the above-mentioned hopper so that it can be pulled out and pushed in freely, and the supply port is opened by pulling out the lid that also serves as a supply table. In such cases, the above-mentioned lid can be used as a supply platform to save labor in carrying in the paddy, and at the same time, the suction air from the suction fan can be circulated through the loading hopper to shorten the time it takes for people to fall into the unloading tank. The present invention also aims to provide a suction-type paddy drying device that can perform smooth suction drying work as a lid that prevents outside air from entering into the take-out tank from the hopper when the supply port is covered by pushing it in. DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the device according to the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a dryer main body which has a substantially hermetic shape as a whole, and inside the dryer main body 1, a tempering tank 2, a ventilation drying cylinder,
The take-out tanks 4 are sequentially stacked three-dimensionally facing downward, and inside the ventilation drying cylinder 3 there is a fume frame 6 that communicates with the hot air generation cylinder 5 arranged on the front of the dryer main body 1, and a lower end is connected to the take-out tank 4. A plurality of communicating exhaust frames 7 are arranged vertically in a plurality of rows alternately via a paddy flow path 8.

At the bottom of the take-out tank 4, a take-out screw 9 whose one side is connected to the lower part of the elevator 10 is installed horizontally.
The upper part of the refining tank 2 is connected to a carrying-in device 11 arranged at the upper part of the refining tank 2 .

Reference numeral 12 denotes a feed-out roll that is axially suspended at the lower part of the paddy channel 8.

The front wall 13 of the take-out tank 4 constructed as described above is provided with a feeding hopper 14 having a supply port 15 and a droplet 16 at the upper and lower positions communicating with the take-out tank 4. The suction and exhaust fans 18 whose sides face the inside of the extraction tank 4 are mounted so as to face each other.

A leg 20 is provided at the supply port 15 of the above-mentioned tensioning hopper 14.
A lid 19 that also serves as a supply stand is attached so that it can be pulled out and pushed in freely.

As shown in FIGS. 3 and 4, the means for engaging the lid 19 which also serves as a supply stand is provided with horizontally long engagement grooves 21 at the upper portions of both left and right sides of the hopper 14. A shaped locking piece 22 is fitted on both the left and right sides of the lid 19 which also serves as a stand, and the above-mentioned locking means may be formed by another structure.

Therefore, when the above-mentioned supply stand lid 19 is pulled out as shown in FIG.
Therefore, it may be a scam that the paddy can be put into the loading hopper 14 in a labor-saving manner by quickly changing it to a loading table such as a paddy bag (not shown). By circulating suction air into the tensioning hopper 14, it is possible to accelerate the dropping speed of paddy and shorten the paddy tensioning time.

In addition, when the lid 19 that also serves as a supply stand is pushed into the position indicated by the chain line in FIG. Perform drying work.

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

In this figure, when carrying in paddy, there is a carrying screw 9, an elevator 10, a carrying device 11, and a suction exhaust fan 18.
When the supply stand lid 19 is pulled out to the position indicated by the solid line in FIG. -14, and is sucked and distributed into the extraction tank 4.

Therefore, if a paddy bag or the like is placed on the supply table 19a and the paddy is put into the loading hopper 14, the paddy is quickly transported by the circulating suction air without scattering dust around it. Then, the grains fall into the take-out tank 4 through the drop port 16, pass through the carry-out screw 9, the elevator 10, and the carry-in device 11, and are filled into the tempering tank 2 and the paddy channel 8.

Therefore, if a predetermined amount of paddy is fed using the supply table 19a, filling can be done in a short time with labor saving, and the task of sorting out dust mixed in the paddy can be accomplished at the same time.

When the paddy loading work is completed as described above, by pushing the supply stand lid 19 from the solid line position in FIG. 3 to the chain line position, the supply port 15 is closed by the lid 19b, thereby preventing outside air from entering.

Therefore, if combustion hot air is generated in the hot air generation cylinder 5 and the delivery roll 12 is rotated, the suction exhaust fan 1
The dry hot air sucked and introduced into the fume frame 6 by the suction action of 8 is exposed to the paddy flowing down in the paddy flow path 8 sequentially by the rotation of the feed roll 12 while it exits the exhaust frame 7, thereby drying the paddy and drying the paddy as well. The dust generated during drying is quickly concentrated and exhausted to the outside of the machine by the suction/exhaust fan 18 for drying work.

In short, since the present invention has the above-mentioned configuration, all of the paddy loading work can be done at the front of the dryer main body 1.Is it possible that the lid 19 which also serves as a supply stand is connected to the retaining groove 21?
When the paddy is pulled out horizontally along the hopper 14, the paddy can be easily loaded into the loading hopper 14 by quickly changing to the feeding table 19a with legs 20 to save labor, and the loaded paddy can be sucked out. The run-up action of the suction air sucked and distributed into the loading hopper 14 by the suction action of the exhaust fan 18 prevents people from falling into the take-out tank 4 in a short time without stagnation, and prevents dust from scattering. In addition, when the supply port 15 is coated by pressing the supply table/cover 19, the supply port 15 is completely closed and the loading hopper 14 is closed.
The lid 19b prevents outside air from entering into the lid 19b, and the suction force of the suction/exhaust fan 18 is used to circulate the drying hot air, thereby ensuring smooth drying of the paddy.
