Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the left and right expressions described in the specification of the present application are based on the state seen from the cereal supply port 13 side of the threshing apparatus 1 (front view shown in FIGS. 1 and 4). Judgment and description.

  Next, as shown in FIG. 3 and FIG. 4, the threshing apparatus 1 has the sorting chamber 2 disposed below the handling chamber 15 in which the cereal supply port 13 is opened on one side and the handling cylinder 14 is pivoted inside. The handling port 19 that is provided and continuously opened from the grain supply port 13 is provided with a holding and conveying device 18 including a holding rod 16 and a feed chain 17 along the outside. As shown in FIG. 3, the sorting chamber 2 extends rearward from the lower side of the handling chamber 15 and extends from the end portion of the dust removal treatment chamber 8 described later to the dust removal side of the threshing apparatus 1. Yes. As shown in FIG. 3, the sorting chamber 2 is provided with a swing sorting shelf 3 on the upper side, and at a lower position thereof, from the upper side of the sorting direction, the compressed air tang 20, the first transfer spiral 21, and the second transfer spiral. It arrange | positions in order of 22 and is comprised so that transmission can be carried out by each axising on a horizontal axis.

  As shown in FIG. 2 and FIG. 3, the swing sorting shelf 3 is positioned so that the start end portion faces the lower side of the handling chamber 15, and a transfer shelf 3a is provided at this portion, followed by the chaff sheave 3b. The Strollac 3c is disposed at the end portion and is connected to the swing mechanism 23 so as to be sorted while swinging in the front-rear direction. As shown in FIG. 3, the sorting air passage 24 is formed in the sorting chamber 2, but the base portion communicates with the compressed air tang 20 and passes above the first transfer spiral 21 and the second transfer spiral 22. , It is configured to pass through the swing sorting shelf 3 toward the rear cross flow fan 5 side.

  Accordingly, when the sorting air is blasted by the pressure wind 20 and blown out to the sorting air passage 24, it is blown out between the chaff sheaves 3b of the sorting shelf 3 while performing the first sorting and second sorting, and dust is discharged at the rear. Sorting is performed to reach the cross-flow fan 5 side and the Strollac 3c, and the dust is discharged from the rear dust outlet 25 to the outside of the machine. Reference numeral 26 denotes a collecting plate provided on the transfer shelf 3a.

  Next, the second processing chamber 28 and the dust removal processing chamber 8 are arranged such that the second processing chamber 28 is arranged along the left side of the handling chamber 15 as shown in FIGS. The processing chamber 8 has a configuration in which the start end portion communicates with the rear portion of the handling chamber 15 and extends rearward and is positioned on the upper left side of the sorting chamber 2. In the second processing chamber 28, a second processing cylinder 29 is housed and pivoted, and the second product is cerealed and reduced by a second cerealing device 30 communicated with the terminal portion of the second transfer spiral 22. The second processing action is performed. As shown in FIGS. 3 and 6, the dust removal treatment chamber 8 is provided with a dust removal treatment cylinder 31 mounted on an interior shaft, and the start end is opened and communicated with the left end of the end of the treatment chamber 15. The untreated dust collected from the chamber 15 is conveyed backward while being processed and leaked into the sorting chamber 2, and dust is discharged by opening a dust outlet 32 at the end portion.

  As shown in FIG. 6, the dust removal processing cylinder 31 is divided into two parts, a front processing cylinder 31a and a rear processing cylinder 31b, and is pivoted as a single unit. The second processing cylinder 29 on the front side is input, and the rear processing cylinder 31b is input separately from the rear side.

The transmission mechanism will be described later.
As shown in FIGS. 1 and 2, the cross flow fan 5 is provided so as to be pivoted horizontally above the Strollac 3c at the end portion of the swing sorting shelf 3, and the dust suction port 6 is directed downward. The dust outlet 33 is configured to face the outside of the machine. The single-side suction fan 4 is arranged on the left side of the cross flow fan 5 on the side close to the dust removal treatment chamber 8 as shown in the drawing, and a partition wall 34 between the cross flow fan 5 and the side flow fan 5 is provided. It is provided and partitioned, and is configured to be supported on another shaft.

  In this case, the one-side suction fan 4 is located between a left support plate 35 attached to a casing 38, which will be described later, and the right partition wall 34, is supported by the bearings, and is transmitted from the left side. The cross flow fan 5 is configured such that the left end is supported by the partition wall 34 and the right side is supported by the right airframe side plate (side plate) 9, and both fans 4 and 5 are supported on different shafts. ing.

  As shown in FIGS. 1 and 2, the support plate 35 has the transmission sprocket 36 to the right as a shape in which the central bearing portion is offset to the right side (center side of the one-side suction fan 4) in a concave shape. The diffusion processing cylinder 10 to be described later is designed to be as long as possible. Then, as shown in FIG. 8, the one-side suction fan 4 opens the dust suction port 7 in the support plate 35 so as to face the dust processing chamber 8 side, and directs the dust suction port 37 to the outside at the rear part. It has an open configuration.

  The one-side suction fan 4 and the cross-flow fan 5 are formed so that the outer diameters of the fans 4 and 5 are substantially equal to each other as shown in FIGS. The casing 38 to be covered and the separation plate 39 provided on the outlet side (dust exhaust ports 33 and 37) are shared.

Next, as shown in the drawing, the diffusion processing cylinder 10 is positioned close to the upper surface of the swing sorting shelf 3 at a position lower than the one-side suction fan 4, and is moved closer to the left side of the body side plate 9 side. The diffusion processing cylinder driving case (processing cylinder driving case) 43 provided outside the side plate 9 is pivotally mounted in a cantilever state. In the case of the embodiment, the diffusion processing cylinder 10 is located between the one-side suction fan 4 and the left body side plate 9 in the front view shown in FIG. 1 or the side view shown in FIG. It is set as the structure which exists in the fall position of the processed material in the downward position of the dust processing chamber 8. FIG.

  In this way, the diffusion treatment cylinder 10 is supported in a cantilever manner by a strong diffusion treatment cylinder drive case 43 (see FIGS. 2, 6, 9, and 10) provided outside the left fuselage side plate 9. Therefore, the right side is opened to solve problems such as stagnation and catching of the processed material, and transmission to the one-side suction fan 4 can be achieved.

As shown in FIGS. 9 and 10, the diffusion processing cylinder 10 is provided with a plurality of tooth teeth (processing teeth) 40 having lead angles in the rotation direction, and is provided on the left side portion on the swing sorting shelf 3. A configuration in which dust that is higher than a certain layer thickness that rises and dust that falls from the dust treatment chamber 8 can be diffused obliquely forward on the shelf on the front side of the crossflow fan 5. It is said. As shown in FIG. 1, the diffusion processing cylinder 10 forms a range 11 in which the tooth teeth 40 are not provided in a certain range on the left side, and the portion 11 is provided close to the side wall 41 of the swing sorting shelf 3. In the side view, the side wall 41 and the tooth 40 are configured to wrap left and right.

  When configured in this manner, the diffusion processing cylinder 10 can approach the left side of the machine body side plate 9 and can also approach the vertical relationship with the swing sorting shelf 3 side, lowering the overall machine body height and providing sufficient diffusion function. It can be used to increase the sorting efficiency. The diffusion treatment cylinder 10 differs depending on the variety and maturity of rice, but when the untreated material deposit layer is thickened on the left side of the swing sorting shelf 3, these are converted into tooth teeth having a lead angle as they rotate. 40 can be diffused diagonally forward onto the shelf 3 on the front side of the crossflow fan 5. As a result, the diffusion processing cylinder 10 of the present plan greatly reduces the amount of second reduction and reduces the amount of grains scattered outside the machine as dust, as compared to a conventional threshing apparatus without a diffusion processing cylinder. The loss can be reduced.

As shown by the arrow in FIG. 3, the diffusion processing cylinder 4 rotates in the same direction as the cross-flow fan 5 in the clockwise direction when viewed from the right machine body side plate 9 side.
As shown in FIG. 11, the diffusion processing cylinder 10 may be configured such that a spiral processing tooth 42 is attached instead of the tooth 40. When the processed material on the swing sorting shelf 3 reaches a certain level or higher, the spiral processing teeth 42 continuously act on the high portion to ensure that the spiral processing teeth 42 are on the shelf 3 on the front side of the cross flow fan 5. There is a feature that can be sent while jumping diagonally toward the.

  Furthermore, since the helical treatment tooth 42 has a continuous helical shape, the number of collisions with the processed material including the grains is smaller than that of the discontinuous tooth 40, and the occurrence of damaged grains can be greatly reduced. There is.

Below, the transmission mechanism of the threshing apparatus 1 is demonstrated.
First, as shown in FIG. 13, the engine 60 branches the output rotational power into two, and inputs one to the traveling mission device 62 via the hydrostatic continuously variable transmission 61 and the other to the threshing device. 1 is input. The threshing apparatus 1 uses the power input to the Karatsu shaft 63 to handle the handling cylinder 14 and the second processing cylinder 29, the oscillation mechanism 23 and the feed chain 17 side of the oscillation sorting apparatus 3, and the pressure. Of course, the wind tang 20 is branched and transmitted to the second transfer spirals 21 and 22 side.

  As shown in FIG. 13, the dust removal processing cylinder 31 is configured such that the front processing cylinder 31 a is transmitted integrally with the second processing cylinder 29. The rear processing cylinder 31 b is configured to be transmitted via the second transfer spiral 22 and further from the transmission pulley 65 via the first transmission case 66. The second transmission case 67 is transmitted from the first transmission case 66 and is transmitted to the one-side suction fan 4 via the diffusion processing cylinder 10.

On the other hand, the cross flow fan 5 is configured to be transmitted from the second transfer spiral 22 via the counter shaft 69 and the transmission pulley 70 as shown in FIG.
As described above, the cross flow fan 5, the diffusion processing cylinder 10, and the one-side suction fan 4 are driven by the former being input from the right airframe side plate 9 side and the latter being input from the left airframe side plate 9 side. The arrangement of the drive driven is as follows.

  Therefore, the transmission mechanism of the threshing apparatus 1 is a crossing that drives the diffusion processing cylinder 10 and the one-side suction fan 4 provided on the left side of the machine body with the power input from the left side, and is pivoted toward the right side of the machine body. Since the flow fan 5 is input and driven from the airframe side plate 9 on the right side, the transmission mechanism is relatively simple and can be manufactured at a low cost.

  With the above configuration, the one-side suction fan 4 can change speed independently without affecting the cross-flow fan 5, and thus can change speed according to the amount of processing, and is usually faster than the cross-flow fan 5. Dust absorption and dust removal are performed while rotating.

  As already described, also in the dust removal processing chamber 8, the dust removal processing cylinder 31 is configured as a separate path for inputting the transmission path between the front processing cylinder 31a and the rear processing cylinder 31b from the front and rear. The trunk 31a rotates at a relatively low rotational speed while suppressing the desorption and damage of the grains in the processing of the dusts inherited from the handling chamber 15, and promotes the formation of single grains such as branch raft adhering grains. The rear processing cylinder 31b is separated from the waste, and the front processing cylinder 31a is rotated at a higher speed than the front processing cylinder 31a to promote the shredding of swarf and the like.

  Then, as shown in the transmission mechanism diagram of FIG. 13 and FIG. 14, the rear processing drum 31 b and the one-side suction fan 4 branch the power to both sides in the first transmission case 66 on the lower side of transmission from the transmission pulley 65. Since the processing cylinder drive belt 72 and the fan drive belt 73 are configured to transmit each other, it is possible to change the speed while the two are synchronized, and the input rotation to both, adjustment and setting of the rotation direction, etc. There is an advantage that becomes easier. Since the above-described rear processing cylinder 31b and the one-side suction fan 4 use the driving belts 72 and 73, respectively, even if rotation reduction occurs in one of them due to an overload condition or contamination of foreign matter, the belt transmission There is also an advantage that slipping occurs with the above characteristics and that adverse effects and damages on the other side can be minimized.

Next, a configuration in which the cross-flow fan 5 and the one-side suction fan 4 are attached to and detached from the threshing apparatus 1 will be described.
First, as shown in FIG. 15, the cross-flow fan 5 and the one-side suction fan 4 are supported by bearings 75 and 75 on the partition wall 34 slidably supported by the casing 38 inside the fuselage. Two supported shafts 76 and 77 are provided, the one-side suction fan 4 is axially attached to one short support shaft 76, and the cross-flow fan 5 is axially attached to the other long support shaft 77. As shown in FIG. 16, the short support shaft 76 forms a coupling portion 79 that freely attaches and detaches the bearing device 78 and the transmission sprocket 36 fixed to the support plate 35 (outside) on the casing 38 side. It is configured. The long support shaft 77 is provided by supporting the bearing device 80 at the end (outside), and the mounting side plate 81 is integrally supported by the bearing device 80. The bearing device 80 is configured to integrally support a pair of meshed counter gears 82 and 83 and a transmission pulley 70 on the outside thereof.

  Then, as shown in FIG. 17, the threshing apparatus 1 forms an insertion hole 85 having a diameter that allows the one-side suction fan 4 and the cross-flow fan 5 to be inserted into the right-side machine body side plate 9. The two fans 4 and 5 are inserted and pulled out. In this case, when the one-side suction fan 4 and the cross-flow fan 5 are inserted into the insertion hole 85, they are inserted from the machine body side plate 9 on the right side of the threshing apparatus 1 along the inner space of the casing 38 inside the machine body. The end portion (left end portion) of the support shaft 76 is inserted into and supported by the bearing device 78 fixed to the support plate 35, and the mounting side plate 81 fixed to the end portion of the support shaft 77 is attached to the right body side plate 9. It is set as the structure which piles up on the outer side of this, and it fixes by screwing.

  As described above, the cross-flow fan 5 can be pulled out by simply removing the drive belt 86 shown in FIG. 17 and then unscrewing the machine-side plate 9 and removing the mounting side plate 81 for cleaning and maintenance. . Further, in the embodiment, as shown in FIG. 15, the attachment side plate 81 can be removed while supporting the pair of counter gears 82 and 83 and the transmission pulley 70, and it takes time and effort to disassemble the transmission mechanism. There is a feature that can be attached and detached relatively easily.

  In the case of the embodiment, the one-side suction fan 4 is formed so that the transmission sprocket 36 is detachable by forming a coupling portion 79 at the shaft end of the short support shaft 76 that supports the fan. Since it can be removed as a unit, cleaning and maintenance can be performed together with the cross-flow fan 5. In this case as well, there is an advantage that the transmission mechanism of the one-side suction fan 4 is not required to be disassembled or removed, and it does not require much time for attachment / detachment.

  Further, in the embodiment, since the partition wall 34 for partitioning the fans 4 and 5 is integrally removed, the internal space of the casing 38 can be greatly opened, and the inner corners can be cleaned, and maintenance is easy. There is an excellent feature that has been greatly improved.

  Next, the vehicle speed (in this case, "working speed") is set for one transmission system that transmits the rear processing cylinder 31b, the diffusion processing cylinder 10, and the one-side suction fan 4, and the other transmission system that transmits the cross-flow fan 5. The following description will be made on the structure for performing the shift control by following the same. Since each of these devices increases the work efficiency by shifting the speed of the combine vehicle to the high speed side, naturally, the amount of threshing processing increases. It is necessary to increase the processing speed by increasing the rotation speed.

  Therefore, as shown in FIG. 18, the unillustrated combine is provided with a main speed change lever 90, and by operating this, the hydrostatic continuously variable transmission 61 shown in the transmission mechanism shown in FIG. It is configured such that the rotational speed transmitted through the traveling mission device 62 is transmitted to the crawler to change the vehicle speed. The shift operation amount of the main shift operation lever 90 is detected by a potentiometer 89 provided in a connected manner and input to a controller (not shown) as can be seen from the drawing.

Therefore, a configuration in which the transmission system that transmits the rear processing cylinder 31b, the diffusion processing cylinder 10, and the one-side suction fan 4 performs shift control following the vehicle speed will be described.
First, as shown in FIGS. 19 and 20, the control motor 91 is provided with the pinion gear 92 meshed with the rack gear 93, and pushes and pulls the control lot 95 via the interlocking arm 94 to drive the belt of the transmission pulley 65. The diameter is adjusted and adjusted. Reference numeral 96 denotes a tension pulley.

  Further, as shown in FIGS. 19 and 20 (see FIG. 13), the left pulley 97 of the second transfer spiral 22 has the transmission pulley 98 wound around the transmission pulley 65 so that the tension pulley 96 is always on. It is configured to transmit in a tensioned state.

  In the above configuration, the transmission pulley 65 is decelerated when the rotation diameter is enlarged, and is accelerated when the rotation diameter is reduced, and rotational power is input to the first transmission case 66 shown in FIG. The processing cylinder 31b, the diffusion processing cylinder 10, and the one-side suction fan 4 can be shifted. In this case, the control motor 91 controls the rotation direction and the rotation range on the basis of a control signal output from the controller (not shown) to drive the pinion gear 92, and the rack gear 93, the interlocking arm 94, and the control lot 95. The transmission pulley 65 is operated via

  As described above, the rear processing cylinder 31b, the diffusion processing cylinder 10, and the one-side suction fan 4 that are configured by one transmission system have the vehicle speed changed by the speed change operation of the main speed change operation lever 90, that is, the working speed. Following up and down is automatically controlled to increase / decrease, and processing can be performed accurately while responding to changes in processing volume. Therefore, each device is controlled to the high speed side during high-speed running to process the stagnation of the processed material with high efficiency, and at low speed, it is decelerated to the appropriate rotation speed and properly processed to prevent damage particles. Occurrence can be prevented.

  In the above embodiment, since the rear processing cylinder 31b, the diffusion processing cylinder 10 and the one-side suction fan 4 are in one transmission system, the gear ratio is substantially the same, and the speed is changed in parallel. ing.

  The rear processing cylinder 31b, the diffusion processing cylinder 10, and the one-side suction fan 4 set the minimum speed to an intermediate speed (the rotational speed having the minimum processing capacity necessary in any case), and It is desirable that the shift control be performed only on the higher speed side.

  Next, as shown in FIG. 21, the cross flow fan 5 meshes the pinion gear 92 driven by the control motor 91 with the rack gear 93 and pushes and pulls the control lot 95 via the interlocking arm 94 to change the speed change pulley. The transmission diameter of 70 is adjusted to be enlarged or reduced. As described with reference to FIG. 13, the transmission pulley 70 is transmitted from the pulley 99 of the counter shaft 69 by the drive belt 86, and a tension pulley 96 is provided at an intermediate position.

  Thus, as shown in FIG. 21 (see FIG. 13), the cross-flow fan 5 is controlled so that the control motor 91 is controlled by a control signal output from a controller (not shown) to follow the vehicle speed. is there.

  As described above, the cross-flow fan 5 is characterized by being able to work while adjusting the processing capacity in accordance with the increasing / decreasing processing amount by performing the shift control following the shift of the vehicle speed (working speed). . Then, as described above, in the cross flow fan 5, the diffusion processing cylinder 4 is shifted corresponding to the shift of the working speed, and the processed material is diffused on the swing sorting shelf 3 in front of the cross flow fan 5. At this time, it was possible to cope with this, and it became possible to perform an appropriate dust disposal operation.

  As described above, the shift control mechanism shifts the rear processing cylinder 31b, the diffusion processing cylinder 10, and the one-side suction fan 4 to the machine body side plate 9 on the left side of the threshing apparatus 1, and the cross flow fan 5 is installed. Since the mechanism for shifting gears is mounted on the right body side plate 9, the structure is relatively simple and can be manufactured at a low cost, and the maintenance is easy.

  Next, the amount of the processed material flowing on the swing sorting shelf 3 and the amount of the second processed material flowing in the second processing chamber 28 are detected by a sensor, and the one-side suction type fan 4 and the transverse flow are detected based on the detection information. An embodiment for controlling the speed of the fan 5 will be described.

  First, as shown in FIG. 22 (refer to FIG. 3), the layer thickness sensor 105 detects the processed material flowing on the left and right side portions of the shelf 3 above the swing sorting shelf 3 so as to be separately detected. The thickness sensor 105a and the right layer thickness sensor 105b are provided in a suspended state, and the layer thickness of the processed material is detected by a contact method and input to a controller (not shown).

  In this case, as shown in FIG. 22 (see FIG. 3), the left layer thickness sensor 105a and the right layer thickness sensor 105b are attached to the rear plate 106 located at the lower part of the rear part of the handling chamber 15 and extend downward. In addition, when the processed material on both the left and right sides flowing on the swing sorting shelf 3 at the detection portion at the tip portion reaches a certain level or higher, the layer thickness can be detected separately on the left and right sides.

  When the detection information is input from the left and right layer thickness sensors 105a and 105b, the controller outputs a control signal based on the detection information of the left layer thickness sensor 105a while performing a comparison operation with the stored reference value and the like. The control signal is output to the left control motor 91 (see FIG. 20) and output based on the detection information of the right layer thickness sensor 105b to the right control motor 91 (see FIG. 21) for control. Yes.

  As described above, the operation of the first embodiment will be described with reference to FIG. 22 and FIG. 1. In the control signal output from the controller based on the information detected by the left layer thickness sensor 105a shown in FIG. The speed of the diffusion processing cylinder 10, the one-side suction fan 4, and the rear processing cylinder 31b is controlled. The crossflow fan 5 on the right side is controlled to increase / decrease based on the detection information of the right layer thickness sensor 105b on the right side shown in FIG.

  As described above, according to the first embodiment, the processing product on the swing sorting shelf 3 is dropped into the second reduction amount (in this case, directly from the second processing chamber 28 to the left side on the swing sorting shelf 3). In many cases, the processed material on the shelf 3 does not form a uniform layer on the whole surface due to the size of the material), the moisture content in the processed material, the inclination of the machine, etc. Processing can be performed in response to a biased object.

  Next, in the second embodiment, the shift control of the cross flow fan 5 is performed based on the detection information of the right layer thickness sensor 105b, and the control motors on both the left and right sides are controlled by the control signal based on the detection information of the left layer thickness sensor 105a. 91 is controlled.

  As described above, in the second embodiment, the cross flow fan 5 is configured to perform the shift control regardless of which of the left and right layer thickness sensors 105a and 105b is detected. For example, the left layer thickness sensor 105a However, when only the high layer thickness is detected and the shift control on the left side is performed, the processed material diffused by the diffusion processing cylinder 10 is diffused on the swing sorting shelf 3 in front of the cross-flow fan 5. In order to cope with an increase in the dust processing amount, it is necessary to control the speed of the cross flow fan 5.

Therefore, the cross-flow fan 5 needs to be constantly accelerated regardless of the right side or the left side when the number of workpieces increases on the swing sorting shelf 3.
Next, a configuration in which the second detection sensor 107 is provided in the second processing chamber 28 to detect the increase or decrease in the processing amount in the chamber and perform the shift control will be described.

  First, as shown in FIG. 4, the second detection sensor 107 is provided at an upper position of the second processing chamber 28, and detects the amount of the second object in the room and inputs detection information to the controller. The controller (not shown) is configured to output a control signal to the control motor 91 while performing a comparison operation with a stored reference value or the like when detection information is input from the second detection sensor 107. In this case, the controller is configured to output control signals to the two control motors 91 and 91 installed on both the left and right sides to control the shift of both the one-side suction fan 4 and the cross-flow fan 5.

  As described above, when the second product increases in the second processing chamber 28, the one-side suction fan 4 and the cross-flow fan 5 are speed-controlled to increase the rotational speed and increase the dust processing capacity. Thus, the amount of the second product to be reduced to the second processing chamber 28 can be reduced and prevented before clogging occurs inside the threshing apparatus 1.

  Although various embodiments of the invention according to the present application have been described above, the first feature is the configuration in which the one-side suction fan 4 is provided on the left side of the cross-flow fan 5, and the dust disposal chamber on the side of the machine body. Light swarf and dust in the waste that has been leaked and discharged from 8 is sucked out by the single-side suction fan 4 and discharged outside the machine, greatly reducing the second reductant, and threshing sorting The efficiency is improved and the load of the second processing can be reduced.

  The second feature is that light dust discharged from the dust processing chamber 8 is sucked by the upper one-side suction fan 4 and discharged outside the machine as described above. The heavy dust collected with the grains falling to the right is swung to the right front (meaning the front side of the suction side of the transverse fan 5) by the tooth 40 as the diffusion cylinder 10 rotates. 3, and the dust can be sorted by the crossflow fan 5 while being subjected to rocking sorting.

  The third feature is that the one-side suction fan 4 and the diffusion processing cylinder 10 are transmitted by a transmission path different from the transmission path of the cross-flow fan 5 and input from the airframe side plate 9 side closer to each other. Since it is configured to be transmitted, there is no need to cross the transmission mechanism and it can be simplified.

  Since the transmission path for driving the one-side suction fan 4 and the diffusion processing cylinder 10 and the transmission path for driving the other cross-flow fan 5 are independent paths, they correspond to the respective processing amounts. The processing speed can be changed separately.

  The fourth feature is that the outer diameters of the two fans 4 and 5 are formed to be substantially the same, so that the casing 38 covering the outer periphery and the separation plate 39 provided on the outlet side can be shared, greatly increasing the rigidity of these. In addition, the strength can be ensured and two fans 4 and 5 can be provided, but the fan can be manufactured without increasing the number of parts.
