In the operation of the income of grain drying device, drop into cereal from the either party or two sides of the income mouth 18 that is provided to the device 5 of winnowing, arrive receiving devices 13 by the device 5 of winnowing, from two input ports (A, B or C, D) input, cereal is deposited in the holding tank 2.The operation of this income can not make conveying roller 18 actions that are provided to collection paddy portion 4, therefore, can construct two chevrons in holding tank 2, and makes and roughly pile up cereal in the holding tank equably.
After the income operation was finished, below by drying process, the conveying roller 19 of collection paddy portion 4 began rotation, and begins flowing down and circulating of cereal.Two conveying rollers 19 that are installed on two dry bodies 6 evenly flow down cereal, therefore can make the speed that flows down of the cereal that flows through each dry body 6 also identical.And, as shown in Figure 3, Figure 4, two pressure fans 16 are disposed at the exhaust air box 11 that collects paddy portion 4, the hot blast that two hot blast chambers 10 burner 15 separately that is provided to the left and right directions of drying device produces is supplied with road 30 risings and is supplied in dry body 6 along dry wind separately by the sucking action of pressure fan 16.
Because 180 ° of outfits of two dry body 6 upsets, so hot blast layer 7, drying layer 8, the opposed separately arrangement of air draft layer 9, the distance of the opposed air draft layer 9 of two dry bodies 6 from pressure fan 16 to adjacency, identical with distance from burner 5 to each hot blast layer 7, so can make the wind speed of each layer, air quantity identical.For example, under the situation that does not make the dry body 6 upset configurations of a side, the circulation of each layer and the pressure fan 16 and the wind of burner 15 is apart from different, so different in each dry body 6 by the dry wind of drying layer 8.Particularly, under the different situation, in exhaust air box 9, produce turbulent flow, and produce the different phenomenon of ventilation of each drying layer 8, and be difficult to even drying in two dry bodies 6 in the distance of each air draft layer 9 and pressure fan 16.
By the cereal of drying section, flow down a plurality of chevrons interval 26 on road 12 by the Ji Gu that is connected in each the dry body 6 that collects paddy portion 4, and import, and utilize the rotation of conveying roller 19 to delivery track 19 directions, be discharged to the inclined-plane that Ji Gu flows down road 12 equal and quantitative.In this case, as shown in Figure 4, the side inclined-plane that Ji Gu flows down road 12 is provided with dust discharge path 17, the dust discharge path 17 separately that two Ji Gu flow down road 12 is arranged at exhaust air box 11 opposed to each other, therefore, 10 dry winds that produce are from the warm-air supply district 30 when arriving drying layers 8 by hot blast floor 7 in the hot blast chamber, its a part of dry wind longitudinally makes drying layer 8 ventilate, pass through delivery track 19 from chevron interval 26, the dust discharge path 17 that flows down road 12 from Ji Gu is discharged outside machine by pressure fan 16 then to exhaust air box 11.Dry wind by this dust discharge path 17 flows down cereal that road 12 flows down to Ji Gu and carries out dryly to a certain extent, attracts simultaneously to flow down the dust that cereal produces owing to be the shot shape from conveying roller 19, and it is discharged outside machine.
Dust discharge path 17 flows down road 12 with the space that clips exhaust air box 11 with Ji Gu and is located at same position opposed to each other, therefore, can attract equably from two dust discharge paths 17, can not make to produce turbulent flow in the exhaust air box 11, have and the accumulation of dust in the exhaust air box 11 can be suppressed to minimal effect.
Flow down the cereal that road 12 flows down from Ji Gu and accept the dedusting effect at dust discharge path 17, then, collect device 5 directions of winnowing with the Ji Gu device 4 that is disposed at its lower end, put into the device 5 of winnowing from income mouth 18, circulation in grain drying device 1, dry after the moisture value of setting, discharge from drain tank 34, turn to the operation of back operation.
Fig. 7 is the cross section province sketch map of the drying section 3 of expression second embodiment of the present invention, and expression is provided with one structure respectively with burner 15 and pressure fan 16, and the formation beyond the drying section 3 is identical with the formation shown in the embodiment 1.
In the drying section 3, two dry bodies 6 are disposed side by side along left and right directions, 180 ° of outfits of dry body 6 upsets of a side.In addition, the alignment arrangements of each layer also according to the order of the hot blast layer 7 that crosses left and right directions, drying layer 8, air draft layer 9 or air draft layer 9, drying layer 8, hot blast layer 7 along the fore-and-aft direction repeated configuration, two dry bodies 6 that are the inverted cone shape along with the two ends, the left and right sides of each layer more downwards more of configuration on left and right directions, the space that will be produced by the inverted cone shape of the outer peripheral face of grain drying device and dry body is as dry wind drainage area 30, to produce the space as exhaust zone 31 by dry body 6 inverted cone shape each other, thereby form drying section 3.And, along in each layer that crosses the dry body of left and right directions, if the place ahead of dry body 6 is a hot blast layer 7 then final layer also is a hot blast layer 7, if the place ahead of dry body 6 is an air draft layer 9 then final layer also is an air draft layer 9.
And, hot blast path 27 is equipped with between the side plate of the front of drying section 3 and each dry body 6 and exhaust air box 11,, the dry wind that produces for the attraction that makes the burner 15 that is equipped with by the substantial middle of drying device main body and outer gas does not feed exhaust air box 11, separate the hot blast chamber 10 about dry wind is flowed into equably with confinement plate 35.
Sucking action by the pressure fan 16 of the substantial middle that is disposed at the drying device main body, dry wind by burner 15 generations, in the hot blast path between drying device front side plate and the confinement plate 35 27, arrive hot blast chamber, the left and right sides 10, the drying layer 7 of dry body 6 is by drying layer 8 about being located at from contrast, and arrive exhaust air box 11 from air draft layer 9, be discharged to outside the machine by pressure fan 16 then.The air draft layer 9 that links to each other with exhaust air box 11 is and is symmetrical set, and is therefore even by the dry wind of dry body 6, in addition, also can not make turbulent flow takes place in the exhaust air box 11, thus, can evenly attract, and reduces dust etc. and is piled up in ratio in the exhaust air box 11.
As mentioned above, by using two dry bodies 6 to attract by pressure fan from its central authorities to drying section 3, except can carrying out uniform more drying, the turbulent flow in the exhaust air box is disappeared, thereby can expect to obtain to make the dust effect still less of accumulation.In addition,, and needn't develop the drying section that increases new intensity, also can pass through to use a plurality of existing drying sections, and be provided at intensity, cost, all superior drying section in even drying capacity aspect as dry body even need drying device itself to maximize.
