Description

DETAILED DESCRIPTION OF THE INVENTION The present invention discharges dried paddy outside the machine using the surplus power generated during throttling operation of the far 09E wind machine that performs the suction drying work of the paddy and the work of discharging the paddy outside the machine with a simulated high wind. Dust sorting of dried paddy in a paddy dryer that allows the discharge thrower to be operated lightly and selectively removes dust mixed in the dried paddy by using the suction power of a tomatsu non-air blower. Regarding equipment.

The suction and exhaust fan installed on one side of the take-out tank inside the dryer blows drying air onto the circulating paddy flowing down to dry it, and removes the waste hot air and dust from the drying process outside the machine. A rice grain dryer that performs concentrated 9E abrasion and a rice grain dryer that discharges dried rice that has been dried through the above-mentioned process to the outside of the machine through a discharge thrower were previously developed by the present applicant and are well known.

In the case of the paddy dryer mentioned above, both the suction blower and the discharge thrower are driven by dedicated electric motors installed separately, which makes the paddy dryer expensive and consumes a lot of power. There were drawbacks. Not only that, when the dried paddy is discharged from the machine after the paddy drying process is completed, a lot of dust mixed into the dried paddy flies up from the end of the paddy cylinder into the workplace, creating an unsanitary condition and reducing work efficiency. However, there is a strong desire for a fundamental solution to this problem. In view of the above, the present invention has been developed to connect a vertical pipe of an elevator attached to one side of a paddy dryer to a discharge thrower.
The other end of the dust suction pipe provided on the tin cylinder of the discharge thrower is connected to the suction air passage side of a centrifugal exhaust fan installed in the take-out tank disposed inside the dryer, and the suction air passage and dust suction cylinder are connected to The suction air passage is closed only when the discharge thrower is in a movable state, and at the same time, a pair of on-off valves are pivotally supported to operate in conjunction with each other so as to suitably connect the dust suction tube and the suction air passage. By using a centrifugal blower whose mulling power changes immediately as the air volume increases or decreases, it is possible to carry out paddy circulation drying work, as well as to operate a far-zero blower using the extra power generated during the throttling operation of the centrifugal blower. In addition, the discharge thrower can be operated reliably with a single electric motor, making the dryer inexpensive and economical in power consumption.At the same time, the centrifugal exhaust fan can be operated continuously even after drying is completed. A paddy dryer that reliably separates and removes dust contained in dried paddy discharged outside the machine through a discharge thrower by the suction action of the centrifugal exhaust fan, thereby preventing the dust from scattering around. The present invention is intended to provide a dust sorting device for dry rice, and a preferred embodiment of the structure of the device according to the present invention is shown in the accompanying drawings will be described below.

Reference numeral 1 is a suction-type paddy dryer in which the paddy is dried by being exposed to drying air generated during the process of flowing down. A centrifugal fan 3 is installed on the side, and the turbulent force changes immediately by increasing or decreasing the air volume through a suction air path 4.The centrifugal 9E fan 3 is equipped with a dust exhaust pipe 5, and is used for drying paddy. Concentrate the hot air and dust from the air to the outside of the aircraft.

Reference numeral 6 denotes an elevator attached to one side of the paddy dryer 1, the lower part of the elevator 6 is connected to the take-out tank 2, and the lower part of the supply gutter 7 provided at the upper part is connected to the unloading tank 2. A horizontal gutter 8 for paddy filling or circulating the paddy and a lotus pipe 9 for collecting dried paddy outside the machine are installed, and the horizontal gutter 8 and the lotus pipe 9 are connected to each other. A switching valve 10 is pivotally supported at the boundary position, and the switching valve 10 blocks the horizontal gutter 8 or blocks the delivery pipe 9 by alternately pulling the two left and right traction cords 11 and the first judgment. .

The horizontal gutter 8 described above is horizontally installed above the paddy dryer 1. The lower end of the lotus pipe 9 is connected to the supply side of a discharge thrower 12 mounted at an appropriate height of the elevator 6, and the grain lifting cylinder 13 is connected to the discharge side of the discharge thrower 12. A part of the grain cylinder 13 is formed by a perforated plate 14, and the perforated plate 14 is covered with cover cylinders 15 at appropriate intervals.In addition to the dust suction cylinder 16 whose one end is connected to the cover cylinder 15, The end is opened and connected to the above-mentioned suction air path 4.The above-mentioned centrifugal Hifu fan 3 and elevator 6 are rotated by the driving force of a single electric motor (not shown) disposed on the front side of the paddy dryer 1. In addition, the discharge thrower 12 is operated by transmitting the power from the elevator 6 via a clutch device 17 and a transmission belt 18, and eventually the centrifugal exhaust fan 3, the elevator 6 and The discharge thrower 12 is driven by a single electric motor.
Opening/closing valve 19, 2 for shutting off 6 or making it suitable for operation
0 are each pivotally supported by a movable swivel, and a plurality of actuating valves 22 are connected at one end to a clutch lever 21 that operates the pair of on-off valves 19 and the clutch device 17. The link villages 23, 24, 25, and 26 are interlocked by a lotus connection, and when the operating punch 22 is pushed down, one of the on-off valves 19 is in the position shown by the solid line in FIG. At the same time as opening the dust suction tube 16 with the other on-off valve 20, the clutch device 17 cuts off the power transmission to the discharge thrower 12, and when the working village 22 is pushed up, the suction air passage 4 is closed. close,
The exhaust thrower 12 is operated at the same time as the dust suction cylinder 16 is opened. Next, the operation of the present invention will be explained.

Now rotate the elevator 6 in the drawing.

In this case, the far-D exhaust fan 3 is connected to an appropriate clutch device (
(not shown) to prevent rotation. Next, one side of the towing narrow 11 is pulled, and the lotus passage pipe 9 is pulled by the switching valve holder 01.
After blocking the passage to the side, if the paddy is transported by the elevator 6, the paddy will fall into the horizontal gutter 8 and will pass through the "carrying screw 27".
The rice is filled into the dryer 1 one after another. When a certain amount of paddy is filled in this manner, the paddy loading operation is stopped, and the centrifugal blower 3 is operated and the operating pestle 22 is pushed down. As a result, the suction air passage 4 is opened and at the same time the dust suction tube 16 is closed, and the discharge thrower 12 becomes inactive, and the drying air generated by the suction action of the centrifugal air blower 3 is removed. The paddy flowing through the paddy dryer 1 is sprayed and dried, and the slightly dried paddy is circulated back to the paddy dryer 1 via the elevator 6 and the horizontal gutter 8, where it is dried by several circulation actions. Let it end. When the paddy drying is completed by the above action, the other pulling narrow 11 is pulled and the passage to the horizontal gutter 8 side is closed by the switching action of the switching valve 10, and the passage to the lotus pipe 9 is opened. 22, the suction air passage 4 is closed by one of the on-off valves 19, and instead of being closed by the on-off valve 2 of the dust suction cylinder 16.
0 is also interlocked and released, and at the same time the clutch device 17
The discharge thrower 12 starts operating. However, since the centrifugal exhaust fan 3 has the characteristic that the shaft power changes immediately due to the increase or decrease of the air volume, the diameter of the dust suction tube 16 is smaller than that of the suction air passage 4, and the suction air volume is reduced. Even if the centrifugal cost E fan 3, elevator 6 and discharge thrower 12 are rotated simultaneously, the centrifugal 9E fan 3
The discharge thrower 12 is smoothly rotated using the surplus power generated during the throttling operation, and the dried paddy supplied to the discharge thrower 12 through the transfer pipe 9 is successively discharged from the machine through the tin kernel cylinder 13. At the same time, a large amount of dust contained in the dry rice is sucked into the cover tube 15 through the perforated plate 14 by the suction action of the centrifugal exhaust fan 3, and then concentratedly discharged to the outside of the machine via the dust suction tube 16 and the centrifugal exhaust fan 3. It is possible to prevent dust from scattering to the surrounding area when drying rice is rubbed, and to achieve efficient drying work. In short, since the present invention has the above-mentioned configuration, it is possible to carry out the circulation drying work of paddy by using the far-0 blower 3 whose balling power changes immediately depending on the increase or decrease of the air volume. The centrifugal exhaust fan 3 effectively uses the surplus power generated during the throttle Z operation.
In addition to the operation of the dryer, the operation of the discharge thrower 12 for discharging the dried paddy outside the machine is also accomplished by a single electric motor with a small capacity, thereby making it possible to provide the dryer at a low price and at the same time saving power consumption. As if possible, the suction action of the centrifugal air blower 3 removes the dust contained in the dried paddy during the discharge process, preventing the dust from being scattered around when collecting the dried paddy. This has the effect of allowing sanitary paddy drying work to be carried out.
