る。[Prior Art] Conventionally, a hot air blowing chamber equipped with a burner device on one side and a dust exhaust device equipped with a suction / exhaust device on one side are provided at opposite positions on the left and right sides of the lower half of a dryer main body that is long in the front-rear direction. The extraction chamber, which is provided between the hot air blowing chamber and the dust blowing chamber, is connected to the dust blowing chamber through the dust passage formed by the main and side grain plates to suck and discharge the air. A grain drying device that sucks exhaust hot air and dust discharged into the take-out chamber into the dust-blowing chamber by the suction action of the wind device and centrally discharges the dust to the outside of the machine is disclosed in, for example, Japanese Patent Application Laid-Open No. HEI-2 -97887, it is publicly known.

題点を有していた。[Problems to be solved by the invention] By the way, in the conventional grain drying device of this kind, the suction and exhaust device is operated for the purpose of removing dust while at the same time allowing the grain to be taken out laterally from the dryer main body and loaded into the room. If the grain is stretched to near the height of the upper grain board forming the dust passage, the wind speed of the dust wind passing through the dust passage becomes faster due to the action of sucking air from the outside of the machine, As a result, there is a problem that a part of the grain put into the take-out chamber is sucked into the dust-exhaust air chamber through the dust passage and then scattered outside the machine.

る。The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is to:
Even when the grain is pulled laterally to the dryer body under the operating condition of the suction / exhaust device, the grain stuck in the take-out chamber is exhausted from the dust passage by the suction action. It is an object of the present invention to provide a grain drying device that can reliably prevent the dust drying device from being sucked into the dust chamber and scattered outside the machine.

The hot air blower chamber and the dust exhaust air chamber provided with the suction and exhaust device on one side are provided, and the take-out chamber disposed between the hot air blower chamber and the dust exhaust air chamber is formed by the main and side flow grain boards. In the one connected to the dust-exhaust air chamber through the formed dust passage, the hot-air blowing chamber is provided with a laterally extending hopper obliquely connecting the take-out chamber and the outside of the machine,
An upper end side of the mainstream grain board is connected to the feeding grain board, and a lower end side of the mainstream grain board is extended into the take-out chamber in an inclined shape, and a part thereof is formed as a porous ventilation surface.

内へ次々と投入する。[Operation] Now, install the dryer main body, which is long in the front-rear direction, so as to facilitate the grain loading work, and then operate both the suction / exhaust device and the rotating member of the transport system (for example, the carry-out screw, the elevator and the carry-in device). After the negative pressure is maintained in the extraction chamber as well as in the dust exhaust chamber, the grains are successively fed into the horizontal hopper.

れた後、機外に集中排塵される。By the way, the grain is supplied to the take-out chamber along the horizontal hopper, and at the same time, dust mixed in the grain is sucked from the horizontal hopper through the take-out chamber and the dust passage into the dust wind chamber. After the air is sorted by the sorting air that is circulated, dust is concentrated outside the machine.

まれ、機外に飛散されるという現象を起す。By the way, in the grain filling process as described above, when the height of the grain stuck in the unloading chamber gradually increases and the dust exhaust passage is blocked, the sorting air sucked and circulated in the dust exhaust passage is removed. The wind speed increases, and a part of the grain located near the dust passage is sucked into the dust wind chamber through the dust passage and scattered outside the machine.

た乾燥熱風により乾燥されるものである。However, in the present invention, the mainstream grain board forming the dust passage is connected at its upper end side to the feeding fluid grain board, and at the lower end side is extended to the take-out chamber in an inclined shape, and a part of the mainstream grain board is provided. Since it is formed on the porous ventilation surface, even if a part of the dust passage is blocked by the grain stuck in the take-out chamber, it is sucked into the take-out chamber through the side hopper. The sorting air is sucked into the dust-exhaust air chamber through the ventilation surface provided on the main grain board and then concentrated dust is discharged to the outside of the machine.Therefore, the wind speed in the dust passage is reduced, and the grain in the extraction chamber is exhausted. It is completely prevented from flying out of the machine along with dust. Then, the grain put in the take-out chamber is put in the dryer main body by the rotating member of the conveying system, and is dried by the dry hot air generated in the hot air blowing chamber while being vertically flown down in the dryer main body. It is something.

論のことである。Of course, during the above-described drying operation, the laterally extending hopper is completely closed by an appropriate opening / closing lid.

が損傷されることなく均一に乾燥される。Moreover, since a plurality of rows of the cross-flowing-out delivery chambers 8 are formed immediately below the hot air guide duct 6 and the drying passage 7,
After the grain flow divided in the front-rear direction in the drying passage 7 has passed through the drying passage 7, this time the flow is changed to the left-right direction so that it cross-flows down to efficiently mix and mix grains with different initial moisture contents and at the same time. Improve the liquidity of
It is possible to uniformly dry the grain without unevenness in drying and running. Further, since the cross-flowing-out feeding chamber 8 is always filled with the grain that has been flowed down through the drying passage 7,
The grain is uniformly exposed to the dry hot air flowing from the hot air jet duct 6 through the drying passage 7 in the cross-flow delivery chamber 8 without damaging the grain.

The sorting air is sucked and flowed into the dust-exhaust air chamber through the mainstream grain plate, which partially forms a porous ventilation surface, and is passed through the dust passage. Not only can the wind speed of the sorting air be significantly reduced to prevent some of the grains in the take-out chamber from scattering outside the machine, but the dust that has flowed through the take-out chamber can also be used to remove dust that was blown up during the installation. The wind can be quickly selected.
