Description

[Detailed description of the invention] Industrial applications The present invention relates to a dust suction device for a grain dryer.

Conventional technology Conventionally, a dust suction tube with a mouth-shaped cross section was provided in the hot air chamber to suck in straw waste and dust from the grain collection chamber and the supply trough, and one end of this dust suction tube was connected to an exhaust fan. The end part opens a dust suction port downward into the grain collection chamber, and the straw and dust in the grain collection chamber and the supply trough are sucked in through the dust suction port, and the straw and dust are discharged through the dust suction cylinder. It was a dust suction device that used a fan to suck and discharge dust outside the aircraft.

Problem to be Solved by the Invention While the grains stored in the storage chamber are fed out from the storage chamber into the drying chamber and flowed down, the hot air generated from the burner is sucked by the exhaust fan, thereby removing the drying chamber from the hot air chamber. The grains flowing through the drying chamber are exposed to the hot air and dried, and are supplied to the grain collecting chamber by a transfer spiral inside the grain collecting chamber. From this grain collecting room, the grains are transferred and discharged through the supply gutter into the grain hoist, transported to the upper part of the shell hoist, and fed back into the storage chamber.The cycle is repeated to dry the grains, and during this drying process, dust is absorbed. In a dryer in which straw waste and dust in the grain collection chamber and the supply gutter are sucked through the dust suction port of the cylinder, and the straw and dust in the grain collection chamber and the supply gutter are sucked and discharged outside the machine by the exhaust fan through the dust suction cylinder, the dust of the dust suction cylinder is The distance from the dust suction port to the exhaust fan is long, and as a result, the straw and dust sucked in may cause clogging near the end of the dust suction tube. Also, it sometimes became impossible to suction and discharge the straw waste and dust in the supply gutter.

Means for Solving the Problems According to the present invention, on the lower side of the storage chamber (1) for storing grains,
A drying chamber (2) through which the grains flow down, a hot air chamber (3) between the inside of this drying chamber (2), a ventilation chamber (4) on the outside, and a drying chamber (4) on the outside. A grain collecting room (5) is installed in the machine, and a grain raising machine (6) is installed on one side of the front and rear sides of the machine.
It is provided in communication with a supply gutter (7) provided at the terminal end, and a transfer spiral (8) is provided in this feed gutter (7) and in the grain collecting room (5).
is pivoted to face the grain raising machine (6), and a burner (9) is installed on the front and rear sides of the drying room (2) on the side where the grain raising machine (6) is installed.
A blower (10) is installed on the opposite side of the hot air chamber (10).
3), one end of a dust suction tube (11) is communicated with this exhaust fan (10), and the other end is used to collect straw waste and dust in the grain collecting room (5) and dust in the supply gutter (7). A dust suction port (12) is opened in the grain collecting room (5) at a position close to the supply gutter (7) so as to suck straw waste and dust, and a dust suction port (12) is opened in the left and right side walls of the dust suction cylinder (11). (13) is the configuration of a dust suction device for a grain dryer having an intake port (14) provided at a position close to the exhaust air 41 (10).

Effect of the invention The grains in the storage chamber are transferred from the storage chamber (1) to the drying chamber (2).
The hot air generated from the burner (9) is sucked by the exhaust fan (10) while blowing out the inside and flowing down the drying chamber (2) from the hot air chamber (3), and passes through the exhaust chamber (4) to the drying chamber (2). Exhaust fan (10
), the grains flowing down the drying chamber (2) are exposed to this hot air, dried, supplied to the grain collecting chamber (5), and transported within the grain collecting chamber (5). With a spiral (8), the grain is transferred and discharged from this collection chamber (5) through the supply gutter (7) into the grain raising machine (6), and is transported by this grain raising machine (6) to the storage room (1). The grains are dried by repeating the cycle of supplying them to the inside.

The straw, dust, etc. that get mixed into the dried grains during this drying process are removed from the dust suction port (12) of the dust suction tube (11) when passing through the grain collection chamber (5) and the supply gutter (7). The air inside the hot air chamber (3) is sucked in through the dust suction tube (11), and then sucked and discharged outside the machine by the exhaust fan (10). As a result, the suction air assists the suction and discharge of straw and dust passing through the dust suction tube (11), and the exhaust air II (10) suctions and discharges them outside the machine.

Effects of the Invention With this invention, air is sucked into the vicinity of the exhaust fan (10) on both left and right walls of the dust suction tube (11) that sucks and discharges straw and dust in the grain collection room (5) and the supply gutter (7). By providing the opening (14), the hot air chamber (3) is opened from this intake opening (14).
The air inside is suctioned, and this suction wind causes the dust suction tube (1
1) The straw H and dust in the dust suction tube (11) are assisted and suctioned out.
), straw waste and dust are reliably removed during the drying process, which facilitates the hulling process, which is the post-drying process. The straw and dust that fall into the hot air chamber (3) are also removed from the air inlet (1).
4) By being sucked in and discharged outside the machine, the inside of this hot air chamber (3) is always automatically cleaned, so even if carbon etc. scatters from the burner (9), a fire will not occur. Not at all.
