A dust removal processing chamber 15 is provided at the terminal side of the threshing chamber 2, and the dust removal processing chamber 15 communicates with the threshing chamber 2 to process an object that cannot be processed in the threshing chamber 2. In the embodiment, a second processing chamber 18 having a second processing cylinder 17 coaxially with the processing cylinder 16 of the dust removal processing chamber 15 is provided on the side of the threshing chamber 2, and the second conveyor is provided in the second processing chamber 18. The second end is connected to the end of a second return device (not shown) provided at the end of 14 to process the second item.
In addition, a suction dust exhaust fan (cross flow fan) 20 is provided above the end of the wind sorting chamber 7, and an external discharge port 21 is opened below the suction dust exhaust fan 20. That is, dust and soot are sucked by the air blown by the air blower 5 and the suction wind of the suction dust exhaust fan 20 and discharged from the dust exhaust port 22 to the outside of the machine. The rack 11 discharges from the external discharge port 21 to the outside of the apparatus.
[0008]
Accordingly, a shutter 25 that can be opened and closed is provided at the external discharge port 21. The shutter 25 is formed of a plate member in the left-right direction, and the left and right sides of the shutter 25 are attached to a bearing member 27 provided on the side plate 26 or the fixed portion of the threshing apparatus 1 by an attachment shaft 28 so as to be rotatable up and down. The shutter 25 opens and closes in conjunction with the layer thickness detecting means 32 provided in the waste transporting device 31 that takes over the waste that has been threshed by the grain supply device 30 that supplies the threshing chamber 2 to the threshing chamber 2. Configure.
That is, when the thickness of the waste transported by the waste transporting device 31 is thin, the load on the sorting device S is small, and the third air is discharged because the air blown from the blower 5 is too strong, so the shutter 25 is closed. When the waste layer transported by the waste transporting device 31 is thick, the sorting load is large, so the shutter 25 is opened to quickly discharge the waste and the like out of the machine. Reduce sorting load.
[0009]
The configuration of the layer thickness detecting means 32 and the configuration of the connecting means between the shutter 25 and the layer thickness detecting means 32 are arbitrary. For example, the waste transporting device 31 can be moved up and down below the waste transporting chain 33. The evacuation pin 34 is provided so that the waste is held and conveyed by the evacuation transport chain 33 and the evacuation pin 34, and the evacuation pin 34 is moved upward when the layer thickness of the waste is thin. A part of the layer thickness detecting means 32 is configured to move downward when the layer thickness of the waste is thick.
The upper end of the connecting rod 35 is connected to the evacuation pinching rod 34, the lower end of the connecting rod 35 is attached to the tip of the arm 36, and the base of the arm 36 is fixed to the intermediate shaft 37 that is mounted on the bearing member 27. A cam body 38 is fixed to the intermediate shaft 37, and a roller 39 provided on the mounting shaft 28 is brought into contact with the cam body 38, and when the evacuation clamping rod 34 moves upward, the connecting rod 35 is pulled to pull the shutter 25. When the closing pin 34 is closed, the connecting rod 35 is pushed and the shutter 25 is opened. Therefore, the configuration from the connecting rod 35 to the cam body 38 is a configuration in which the layer thickness detecting means 32 of the waste transporting device 31 and the connecting means of the shutter 25 and the layer thickness detecting means 32 are combined.
Reference numeral 40 denotes a spring that urges the connecting rod 35 to always move upward.
[0010]
Thus, the sheave 10 has a plurality of fins 41 arranged side by side in the swing direction of the swing sorting shelf 8, and each fin 41 is rotatably attached to the swing sorting shelf 8. If the interval is adjustable by standing up to widen and laying down to make the interval narrower, and the interval adjustment of the fins 41 is linked to the opening and closing of the shutter 25, the sorting efficiency of the sorting device S is improved. It is preferable to improve.
In other words, the evacuation pinching rod 34 moves upward when the layer thickness of the evacuation is thin, thereby pulling the connecting rod 35 to close the shutter 25 and interlockingly narrowing the interval between the sheaves 10, When the thickness is large, it moves downward and pushes the connecting rod 35 to open the shutter 25, and the distance between the sheaves 10 is widened in conjunction.
The interlocking means fixes the sheave arm 41 to the intermediate shaft 37, connects one end of a connecting member 42 such as a wire or cable to the sheave arm 41, and connects the other end of the connecting member 42 to the adjusting mechanism 43 of the sheave 10. Connect to. The adjusting mechanism 43 is well known, and each sheave 10 is attached to the swing sorting shelf 8 so as to rotate in conjunction with it, and an arm 44 for rotating any one of the sheaves 10 is connected to the connecting member 42 and the like. Connect the ends. Reference numeral 45 denotes a spring body constituting a part of the connection member 42.
[0011]
Therefore, the shutter 25 is provided with a ventilation portion 46 through which the air from the air blower 5 is passed but the grain is not passed. The configuration of the ventilation portion 46 is arbitrary, and the shutter 25 may be formed in a perforated plate, or may be formed in a lattice or mesh shape.
Thus, the dust removal chamber 15 is positioned on the side of the suction dust exhaust fan 20 so that the dust exhaust treatment chamber 15 and the suction dust exhaust fan 20 are not overlapped, and the shutter 25 is at least suctioned in the rear view. The left and right widths are substantially the same as the dust exhaust fan 20, and the left and right widths do not affect the discharge from the discharge port 46 of the dust discharge processing chamber 15 even if they are large. In the case where the dust disposal chamber 15 is formed long on the end side and overlapped with the suction dust exhaust fan 20 in a side view, in particular, the shutter 25 is not provided on the end side of the dust disposal chamber 15 and the dust disposal process is performed. The width is formed so as not to affect the discharge of the discharge from the discharge port 46 of the chamber 15.
Further, the dust removal processing chamber 15 is configured by surrounding the lower side of the processing cylinder processing cylinder 16 mainly with the processing net 47, and the end of the dust processing chamber 15 is formed in an open opening 48, and the opening 48 has already been formed. A single grain take-out prevention stopper guide 49 is provided to prevent the grain that has been separated from the cereal and moving alone from being discharged.
[0012]
That is, in the dust removal processing chamber 15, the grains fall from the processing net 47 and the swarf is discharged from the opening 48, and when this swarf is discharged, the grains on the processing net 47 are separated from the swarf. The single grains are prevented from being taken out together by the single grain take-out prevention stopper guide 49, and only the sawdust is discharged from the opening 48, and the grains dammed up by the single grain take-out prevention stopper guide 49 are dropped from the processing net 47. Collect without draining out of the machine.
In FIGS. 10 to 12 in the embodiment, the stopper guide 49 for preventing single-grain take-out in plan view is inclined so as to approach the suction dust exhaust fan 20 to the end side with respect to the axial direction of the processing cylinder 16, In this case, the spiral blade 50 of the processing cylinder 16 is operated and discharged, and is dropped from the processing net 47 and recovered without acting on the grains.
13 to 15, the single grain take-out prevention stopper guide 49 is erected in the direction intersecting the axial direction of the processing cylinder 16 and provided at the end of the dust removal processing chamber 15.
[0013]
Thus, a contact body 52 that contacts the transported culm carried by the cereal supply device 30 is allowed to face the threshing chamber discharge port 51 provided at the end of the threshing chamber 2. The contact body 52 is to drop a grain called a stabbed grain that comes into contact with the transported culm of the cereal supply device 30 and enters the culm bundle, is formed in a shaft bar shape, and the lower part is a fixed part. The upper part of the mounting is set as a free end, and it is made to face the grain movement path which the grain supply apparatus 30 conveys. In the embodiment, a plurality of threshing chamber outlets 51 are arranged in the width direction.
Moreover, in the Example of FIGS. 19-21, multiple are provided also in the conveyance direction of the grain supply apparatus 30. FIG. In this case, since the conveyance path which shifts from the grain supply device 30 to the waste conveyance device 31 is formed so as to reach the lower side, the contact body 52 is also a lower contact body with respect to the upper contact body 52. If 52 is positioned high, it is preferable that the contact is ensured.
[0014]
Next, the operation will be described.
When the cereals are supplied to the threshing chamber 2 by the cereal supply device 30, the fallen matter threshed by the rotating handling cylinder 3 in the threshing chamber 2 and dropped from the handling net 4 is placed on the transfer shelf 9 of the swing sorting shelf 8. It falls and is transferred by the transfer protrusion of the transfer shelf 9 to reach the sheave 10.
On the sheave 10, the shavings and the grains are separated by the swinging sheave 10 and the air blown from the air blower 5, and the grains and a little shavings fall from the gap of the sheave 10 and fall from the gap of the sheave 10. The dust that does not fall is moved to the discharge side by the swing of the swing sorting shelf 8 and the blow of the blower 5, and dust and waste are sucked by the suction dust exhaust fan 20 on the terminal side of the wind sorting chamber 7. Waste dust that is excluded and is not sucked by the suction dust exhaust fan 20 reaches the Strollac 11, and waste dust that does not fall from the Strollack 11 is discharged from the discharge outlet 21 to the outside of the machine.
[0015]
In addition, the cereal mash that has been transported by the cereal supply device 30 and has been threshed is taken over by the waste transporting device 31 and transported.
In the above case, the external discharge port 21 is provided with a shutter 25 that can be opened and closed, and the shutter 25 is configured to open and close in conjunction with the layer thickness detecting means 32 provided in the waste conveying device 31. It opens and closes according to the amount of waste discharged by the straw transporting device 31 to prevent the grain from scattering from the external discharge port 21.
That is, when the layer thickness of the waste transported by the waste transporting device 31 is thin, the load on the sorting device S is small, and the air blown from the air blower 5 as it is is too strong and the grains are pulled away from the external discharge port 21. Since this is the third loss, the shutter 25 is closed to reduce the third loss. In particular, when the cutting operation is completed, the second return is small, the sorting wind blown to the Strollac 11 is strong, and the third loss is large. Detected by the layer thickness detecting means 32, the shutter 25 is closed to prevent third loss.
[0016]
Further, when the layer thickness of the waste transported by the waste transporting device 31 is thick, the load on the sorting device S is large. Therefore, the shutter 25 is opened to quickly discharge the waste etc. to the outside of the machine to reduce the sorting load. .
In this case, since the shutter 25 is opened and closed based on the waste transport amount detected by the layer thickness detection means 32, the distance between the detection means 32 and the shutter 25 is short, the configuration is simplified, and the cost is reduced.
This layer thickness detecting means 32 is constituted by an evacuation pinching rod 34 that moves (up and down) with respect to the evacuation conveyance chain 33 of the evacuation conveyance device 31. Therefore, the structure is simplified when the installation location of the shutter 25 and the layer thickness detection means 32 are close to each other.
Further, since the amount of waste transported by the waste transporting device 31 and the amount of non-processed material transferred to the end of the swing sorting shelf 8 are substantially proportional, the configuration is simplified without reducing the control accuracy.
[0017]
Since the displacement movement of the squeezing / clamping bar 34 is mechanically transmitted to the shutter 25 by the connecting rod 35 and the arm 36, it operates reliably.
The lower end of the connecting rod 35 that moves up and down by the movement of the evacuation / clamping rod 34 is attached to the tip of the arm 36, and the base of the arm 36 is fixed to the intermediate shaft 37 mounted on the bearing member 27, and the cam is fixed to the intermediate shaft 37. Since the roller 39 provided on the shutter 25 is in contact with the body 38, the cam body 38 and the roller 39 reliably convert the vertical movement into the opening / closing movement of the shutter 25 and smoothly operates.
Thus, the sheave 10 has a plurality of fins 41 arranged side by side in the swing direction of the swing sorting shelf 8, and each fin 41 is rotatably attached to the swing sorting shelf 8. Since the interval is adjustable by standing up to widen and laying down to make the interval narrower, and the interval adjustment of the fins 41 is linked to the opening and closing of the shutter 25, the selection efficiency of the selection device S Is preferable.
[0018]
In other words, the squeezing pin 34 moves upward when the squeezing layer is thin, thereby pulling the connecting rod 35 to close the shutter 25 and interlockingly narrowing the interval between the sheaves 10 to improve the sorting accuracy. Then, when the layer thickness of the waste is thick, it moves downward and pushes the connecting rod 35 to open the shutter 25, and in conjunction with it, the interval between the sheaves 10 is widened to drop the grains to reduce the load.
In this case, when the evacuation pinching rod 34 moves upward to pull the connecting rod 35 and close the shutter 25, the sheave arm 41 pulls the connection member 42 to rotate the arm 44 of the adjusting mechanism 43 to rotate the sheave. When the interval 10 is reduced and the squeezing pin 34 is moved downward to push the connecting rod 35 to open the shutter 25, the sheave arm 41 is rotated to loosen the connecting member 42 and to move the arm 44 of the adjusting mechanism 43. Rotate to widen the sheave 10 spacing.
[0019]
Since the shutter 25 is provided with a ventilation portion 46 that does not allow grains to pass but allows the air from the air blower 5 to pass through, the air blown from the air blower 5 does not enter the threshing device 1 and the sorted air is not supplied. It works without being disturbed and the sorting becomes good, and the dust is discharged from the ventilation part 46, and the foreign matter entering the second conveyor 14 is reduced to improve the processing efficiency of the second item.
Thus, the dust removal chamber 15 is positioned on the side of the suction dust exhaust fan 20 so that the dust exhaust treatment chamber 15 and the suction dust exhaust fan 20 are not overlapped, and the shutter 25 is at least suctioned in the rear view. Since it is formed in the left and right width which is substantially the same as the dust exhaust fan 20 and does not affect the discharge from the discharge port 46 of the dust treatment chamber 15 even if it is large, the external exhaust on the suction dust exhaust fan 20 side. While the outlet 21 is closed by the shutter 25, the scattering of the grains is prevented, while the outside discharge port 21 on the dust removal processing chamber 15 side is open, so that the waste discharged from the dust removal treatment chamber 15 is open. It is discharged out of the machine from the outside discharge port 21.
[0020]
Thus, the dust removal chamber 15 is surrounded by the processing net 47 mainly on the lower side of the treatment cylinder 16, and the end of the dust treatment chamber 15 is formed as an open opening 48 so as to face the suction dust fan 20. In the case of the above configuration, the opening 48 is provided with a single grain take-out prevention stopper guide 49 that stands upward, so that the grains that have already been separated from the grains and moving alone are discharged together with the sawdust. To prevent.
In the embodiment of FIGS. 10 to 12, the single-grain take-out prevention stopper guide 49 is inclined so as to approach the suction dust exhaust fan 20 as it reaches the end side with respect to the axial direction of the processing cylinder 16 in plan view. The spiral blade 50 of the processing cylinder 16 acts on the sawdust and is transported and discharged as it is, and the grain is dropped from the processing net 47 without the spiral blade 50 acting by the single grain take-off prevention stopper guide 49 and collected. To do.
[0021]
In addition, in the embodiment of FIGS. 13 to 15, the single grain take-out prevention stopper guide 49 is provided in the end of the dust removal processing chamber 15 by being erected in the crossing direction with respect to the axial direction of the processing cylinder 16. The swarf is pushed by the subsequent swarf conveyed by the spiral blade 50, gets over the single grain take-out prevention stopper guide 49 and is discharged to the outside of the machine, and the grain is dammed by the single grain take-out prevention stopper guide 49 and processed. It falls from the net 47 and is collected.
Thus, the threshing chamber outlet 51 provided at the end of the threshing chamber 2 faces the contact body 52 that comes into contact with the transported culm carried by the cereal supply device 30. The cereal while being conveyed contacts the contact body 52 and receives an impact when passing through the contact body 52. Due to this impact, the grain called stabbed grains entering the culm bundle falls and reduces the loss.
[0022]
In this case, since the contact body 52 is formed in the shape of a shaft sticking upward and has an upper portion as a free end, the area that contacts the cereal is small, and the grains fall as they are and accumulate on the contact body 52. To prevent. Further, the contact body 52 may be simply formed of a shaft bar-shaped member protruding upward, so that the cost is not increased.
Since the contact body 52 of an Example is arranged in multiple numbers in the width direction of the threshing room discharge port 51, it contacts the several location of a grain straw and promotes a grain fall.
Moreover, in the Example of FIGS. 13-21, since the plurality is provided also in the conveyance direction of the grain supply apparatus 30, the impact which drops a grain several times during conveyance is given.
Thus, of the fallen objects falling from the sheave 10, pieces of spikes, branches and attached stems, etc. fall into the second receiving tub, and also fall off by swinging the Strollac 11, branches and attached stems, etc. At the same time, it is returned to the second processing chamber 18 by the second return device via the second conveyor 14 and reprocessed.
[0023]
The straw discharge conveying device 31 for conveying the threshing already of straw discharge at the end of the culms supply device 30 for supplying culms de Kokushitsu 2 provided, detecting the thickness of the transfer to straw discharge of the exhaust straw conveying device 31 And a shutter 25 provided at the end of the wind selection chamber 7 for selecting the grains threshed by the layer thickness detecting means 32 and foreign matters is configured to open and close the external discharge port 21. Since the threshing device is used, the threshing device is opened and closed in accordance with the amount of waste conveyed by the waste conveying device 31, so the distance between the detection means 32 and the shutter 25 is short, the configuration is simple, and the cost is low. Before KisoAtsu detecting means 32, the configured to detect the upper and lower Haiwarakyo Ji杆34 perspective moves relative straw discharge conveyor chain 33 of the straw discharge conveying device 31, the said layer thickness detecting means 32 Since the shutter 25 is a threshing device mechanically connected by a connecting rod 35 or the like, the structure is simplified and the cost is reduced by the proximity of the installation location of the shutter 25 and the layer thickness detecting means 32. In addition, since the distance movement of the evacuation pinching rod 34 is mechanically transmitted to the shutter 25, it not only operates reliably, but also in this respect the cost is reduced. Those before the fins 41 of the sheave 10 of the swing sorting shelf 8 provided in Kifusenshitsu 7 is freely gap adjusting, adjusting the distance of the fin 41 which is a threshing apparatus configured to work with the opening and closing of the shutter 25 Therefore, it is preferable to have a rational configuration, reduce the sorting load, and improve the sorting efficiency. Since previous SL shutter 25 is one but impermeable in kernels was threshing device having a vent 46 through which air blown from the blower winnowing fan 5 for blowing air into the air election chamber 7, can discharge the dust from the ventilation unit 46 In addition, the sorting wind from the wind tang 5 acts without being disturbed and the sorting becomes good. Juxtaposed the dust-exhaust processing chamber 15 for processing an object to be processed from dehydration Kokushitsu 2 before Symbol sides threshing chamber 2, the exhaust dust processing chamber 15 is aspirated waste provided at the end of the wind election chamber 7 The shutter 25 is not overlapped with the dust fan 20 in the rear view of the conveyance direction reference, and the shutter 25 is formed to have at least substantially the same left-right width as the suction dust exhaust fan 20 in the rear view. 46. Since the threshing device is formed in a lateral width that does not affect the discharge from 46, the suction dust exhaust fan 20 side of the out-of-machine discharge port 21 is closed by the shutter 25 to prevent grain scattering and dust discharge. Sawdust is discharged from the external discharge port 21 on the processing chamber 15 side.
