FIG. 1 is a left side view of a combine for harvesting grains according to an embodiment of the present invention, FIG. 2 is a front elevation view of the combine, and FIG. 3 is a plan view of the combine. 4 is a partial cutaway side cross-sectional view of the combine threshing device, FIG. 5 is a plan cross-sectional view of the threshing device taken along the line BB in FIG. 4, and FIG. 6 is a line C-C in FIG. FIG. 8 is an elevational sectional view of the threshing device as viewed from above, and FIG. 7 is an elevational cross-sectional view of the rear portion of the threshing device as viewed in the direction of arrows D-D in FIG.

The combine 1 shown in FIGS. 1 to 3 has a pair of left and right crawlers 4 formed in an endless belt shape using a flexible material such as rubber at the lower part of the traveling frame 2, and not only in dry fields but also in wet fields. Also has a traveling device 3 that can travel freely even if the crawler 4 slightly sinks, a reaping device 6 is mounted on the front portion of the traveling frame 2, and an engine (not shown) is provided on the upper portion of the traveling frame 2. The threshing device 15, the Glen tank 30, and the cockpit 20 are mounted.

The mowing device 6 is constructed so that the whole mowing device 6 can be moved up and down by the expansion and contraction action of a mowing lifting cylinder (not shown) to mow the grain stalks vegetated in the field at a predetermined height. A weeding tool 7 is arranged below the front end of the mowing device 6, an inclined grain culm raising device 8 is arranged behind it, and a cutting blade (not shown) is arranged at the rear bottom part thereof. Cutting blade and threshing device 1
5, a front transport device, a handling depth adjusting device, a supply transport device, and the like are arranged between the feed chain 14 and the starting end portion thereof so that the grain can be continuously transferred and the handling depth can be adjusted.

The harvesting device 6 of the combine 1 is operated as follows. First, the engine is started and the operating lever (for HST or Belcon) is operated so that the combine 1 moves forward, and the reaping threshing clutch is turned on to transmit each rotating part of the machine body, and the traveling frame 2 travels forward. Then, the harvesting and threshing work is started. The grain culm to be planted in the field is subjected to the weeding action by the weeding tool 7 located at the lower front end of the cutting device 6, and then raised to the upright state if it is in the lodging state by the raising action of the grain culm raising device 8. The root of the grain culm reaches the cutting blade and is mowed, scraped by the front transport device and transported to the rear, inherited by the handling depth adjusting device and supply transport device (not shown), and successively in the continuous state at the rear. It is transported upward.

The grain culm which is sent from the reaping device 6 after adjusting the handling depth is inserted into the handling chamber 66 through the inlet 66a of the handling chamber 66 which is the main threshing section (see FIG. 6). The handling barrel 69, which is mounted on the handling chamber 66, is provided with a large number of handling teeth 69a on the surface thereof, and the drive mechanism (not shown) transmits the power from the engine through the cutting threshing clutch, as shown in FIGS. 6 rotates in the direction of arrow B. The grain culm with the grain inserted into the handling chamber 66 is pinched between the feed chain 14 moving along the rail guide 14c and the feed chain pinching rod 14a biased by the spring 14b. While being transferred in the direction of arrow A in FIGS. 4 and 5, threshing is caused by the interaction between the handling teeth 69a of the handling barrel 69 and the handling net 74 that rotate in the direction of arrow B. The object to be processed (grains and straw debris) separated from the grain culm passes through the handling net 74 in the direction of arrow C1 (FIG. 6) and is received by the swing shelf 51. Since the rocking rack 51 rocks in the up-down and front-rear directions by the operation of a rocking rack driving mechanism (not shown), the object to be processed is moved in the direction of arrow D (FIG. 4) and receives wind from the Karato 79 to select the wind force. The grains having a high specific gravity pass through the sheave 53 and the sorting net 63 in the direction of the arrow E, are accumulated on the first shelf board 64, and are conveyed from the first spiral 65 to the highest fried cylinder 16 to the grain tank 30. It

A grain tank spiral (not shown) for grain transfer is provided at the bottom of the grain tank 30, and a spiral drive shaft (not shown) for driving the grain tank spiral is composed of a vertical auger 18 and a horizontal auger 19. The discharge auger is connected to discharge the grain stored in the grain tank 30 to the outside of the combine 1 through the discharge auger discharge port. Glentank spiral, vertical auger spiral (not shown) and horizontal auger spiral (not shown)
Are driven to rotate by the transmission of the power of the engine, and convey the stored grain to the outside of the combine 1 by the screw conveyor action of each spiral blade.

Among the objects to be processed on the rocking rack 51, the light ones are blown away by the rocking action of the rocking rack 51 and the blast of the Kara 79, and move on the sheave 53 in the direction of the arrow D to move the straw. The second grain having a small size on the rack 62 drops in the direction of the arrow G and is collected on the second shelf plate 85, and is conveyed to the second fried grain cylinder 87 by the second spiral 86 (FIG. 4).

A second fan 88 is disposed inside the case 80 on the side of the second spiral 86 below the swinging rack 64. The second fan 88 blows air upward from below the strora rack 51 to perform a second treatment. Promotes separation of objects.

The second grain is a normal grain, a branch grain, a mixture of straw chips and clam grains in which the normal grain is stuck in the straw chips. By the second fried cylinder spiral, it is pumped in the direction of arrow H (see FIGS. 4 and 6),
It is discharged from the second processing chamber inlet to above the second processing chamber 67. The second processing cylinder 70 mounted on the lower portion of the second processing chamber 67 is rotated in the direction of arrow J in FIGS. 5 and 6 by a driving device (not shown). The No. 2 kernel is separated from the No. 2 kernel and the branching grain while advancing in the direction of arrow I (FIGS. 4 and 5) while colliding with a large number of treated teeth 70a planted in the No. 2 treating cylinder 70. After removing the branch stem, some of the objects to be processed are the second processing cylinder receiving net 75
From the second processing chamber 67 to the blast of the second processing cylinder blast blade 70b, and most of the object to be processed is sent from the end of the second processing chamber 67 to the blast of the second processing cylinder blast blade 70b. In the direction (FIG. 4), it falls on the rocking shelf 51 and merges with the object to be processed from the handling chamber 66.

A long object such as straw that has reached the end of the handling chamber 66 is thrown into the dust processing chamber 68 from the dust processing chamber inlet 68a in the direction of arrow A2 (FIG. 5). ,
Proceed through the dust treatment chamber 68 in the direction of arrow K, and the second treatment cylinder 7
Spiral 7 around the dust removal cylinder 71 that rotates together with 0
Processing is carried out by the processing teeth planted in the spiral 71a while being conveyed by 1a, and the remaining grains and straw debris are crushed, and the dust processing cylinder receiving net 76 is moved in the direction of arrow C4 (Fig. 4). It passes and falls on the rocking shelf 51.

As shown in FIGS. 4 and 5, the threshing device 1
5 is provided with a cross-flow fan 91, and among the dust generated in the threshing device 15 including the dust treatment chamber 68, air including straw dust, branch and dust that has a low specific gravity is blown by the cross-flow fan impeller 91a. Is blown by the rotation of the blower, blows off in the direction of the arrow L from the cross flow fan outlet 91b, and is discharged to the outside of the combine 1.

Of the dust discharged from the dust treatment chamber 68 to the end of the swing shelf 51 as shown by the arrow M (FIG. 4), the dust having a small diameter and a large specific gravity, such as a grain, is the end of the swing shelf 51. After passing through a part of the straw rack 62 or the sheave 53 in the direction of the arrow G, it falls on the second shelf plate 85 and is processed again in the second processing chamber 67. Of the dust that has fallen from the dust treatment chamber 68 to the end of the swing shelf 51 as indicated by the arrow M, a slightly longer straw debris is received by the Straw rack 62, and the swing motion of the swing shelf 51 and the sardine 79. Rocking shelves 5 as indicated by arrow F
It is discharged from the terminal end of No. 1 and discharged to the field.

The threshed grain culms among the objects to be processed which have advanced in the handling chamber 66 in the direction of arrow A in FIG. It is conveyed in the A1 direction and put into the straw processing chamber 95 (FIGS. 5 and 7). The straw processing chamber 95 has an inlet damper 95a that opens and closes in the horizontal direction to open or close the inlet. When the inlet damper 95a is opened, the straw is in the arrow P direction (FIG. 7). Then, it is cut by the straw cutters 92, 93. The straw cutters 92 and 93 are rotationally driven at rotational speeds controlled by drive actuators M3 and M4, respectively. The straw that has been finely cut by the straw cutters 92 and 93 is diffused in the axial direction (the width direction of the combine 1) by the spiral diffusion means 94 that is rotationally driven by the drive actuator M5, and is dropped and discharged into the field.

When the inlet damper 95a of the straw processing chamber 95 is closed at the position shown by the reference line in FIG. 7 for the dropper work of naturally dropping the straw without cutting it with the cutter 92, the straw is used for straw. It is configured to fall in the direction of arrow Q (FIG. 7) and be released to the field without being cut by the cutter 92.

With the above-mentioned combine structure, one of the features of this embodiment is that the first shelf 64 is the second fan 88.
The casing 80 is a part of the casing 80, and the end portion of the casing 80 is arranged rearward in the vertical direction from the outlet of the second fan 88, and the elastic body 101e is provided at the end portion.
Between the rocking shelf 51 and the first shelf plate 64, the first shelf edge 101a that contributes to the selection of the most processed product is provided.

The end of the first shelf 101a is the first shelf plate 64.
The vertical position of the end part of the device is almost the same as or the rear position. Further, the elastic body 101d is attached to the first shelf edge 101a on the front side of the combine from the first shelf edge 101a so as to be in close contact with the elastic body 101e of the first shelf plate 64.

The end of the first shelf 64 and the first shelf 101
Since the elastic body 101d attached to the terminal end portion of a is located rearward of the outlet of the second fan 88, the first shelf edge 101a
It prevents the processed grain discharged backward from the device from jumping into the second fan case 80. In addition, the elastic body 101
Since d is in close contact with the elastic body 101e at the front end of the shelf plate 64, the processed material does not get into the space between the shelf plates 64 most at the shelf edge 101a.

Further, since the elastic body 101e made of an elastic body is provided at the end of the first shelf plate 64, the rocking shelf 51 can be easily taken in and out of the combine by its deformation.

Further, as shown in FIG.
A guide 1 that rotates around a rotation fulcrum 102a below
When 02 is provided and the throughput is small, the guide 102 is set up at the position shown by the dotted line to guide the air blown from the second fan 88 to the side of the cross flow fan 91. When the throughput is small, the guide 102 is set up to prevent the grains from jumping out of the threshing device area. Further, when the processing amount is large, the guide 102 is rotated in the direction of tilting to guide the second fan 88 to the second spiral 86 side in the entire area of the Straw rack 62 to prevent straw waste from being mixed in the second processed material. To do.

As shown in FIG. 8, a slit 80a is provided on the lower side of the case 80 of the plate fan type second fan 88, and a plate member 80b on the rear side of the slit constituting the slit 80a is guided by a mudguard. You may use a long thing to have a function.

In this case, by sucking air from the slit 80a, it is possible to blow air uniformly over the entire width of the plate fan type second fan 88.

In order to secure the amount of air blown by the second fan 88, it is necessary to provide an opening portion for intake under the fan 88, but since the crawler 4 is located under the second fan 88, the mud of the second fan 88 will be removed. Need preventive measures.

Therefore, in the example shown in FIG. 8, the guide plate 80b
Is attached to the rear of the slit 80a, it is possible to prevent the mud splashing from the crawler 4 from entering the inside of the fan 88.

Since the second fan 88 has a small diameter, a plate fan type fan is used. However, when the width of the second fan 88 is wide, there is a drawback that the air blowing ability at the center in the width direction becomes weak. Also, if a sirocco fan is used as the second fan 88, the plate fan type fan does not have the drawbacks, but since the intake port is located below the sirocco fan, mud or the like easily enters the fan 88, so that the crawler 4 is not easily affected. Need a guide to install.

Therefore, as shown in the rear view of the combine combiner shown in FIG. 9, the upper part of the crawler 4 of the second fan 88 is composed of the plate fan 88f, and the right part in the traveling direction thereof is composed of the sirocco fan 88g. You can

By providing the plate fan 88f on the crawler 4 in the fan structure shown in FIG. 9, since mud does not enter the inside of the fan 88f and the width of the fan 88f is narrow, the fan 88f has a uniform width direction. The wind will start to blow. Further, since the sirocco fan 88g is provided in a portion other than the upward direction of the crawler 4, there is no possibility that mud will invade, and it is possible to secure a uniform air flow rate throughout the fan, which is a feature of the sirocco fan 88g.

FIG. 10 shows another example of the mud splash prevention device of the second fan 88 for preventing the mud splash from the crawler 4. The example of FIG. 10 is a mudguard device having a configuration in which a plurality of guard plates 104 are suspended in a substantially vertical direction in parallel with each other from the lower opening of the second fan 88. .

In the example shown in FIG. 10, the second fan 88 is used.
Since the lower part of the is largely opened, a sufficient amount of air can be secured, and since all the guard plates 104 are suspended at equal intervals in the vertical direction, the suction effect of the sorting air is not hindered. Further, the suction force of the second fan 88 is comparable to the conventional state in which no guard plate is provided.

Furthermore, when the combine is not in work such as mowing and threshing and is in traveling, or when the amount of rice to be selected is reduced and the third loss is increased, such as during turning and low speed work, All the guard plates 104 can be tilted as shown by the dotted line position to close the lower opening of the second fan 88. The motor is driven to swing the guard plate 104 to the dotted line position.

Thus, the second fan 8 shown in FIG.
The mud splash prevention device of 8 is configured to automatically rotate the guard plate 104 in the closing direction during turning of the combine or when the amount of the processed object is small, in connection with the selection control of the processed object such as the grain. There is an advantage that not only the sorting air of the second fan 88 can be weakened, but also the suction effect of the sorting air is great at the time of sorting the objects to be processed.

As shown in the plan view of FIG. 5, the cross-flow fan 91 is located behind the rocking rack 51 and on the left side of the dust processing cylinder 71 in the traveling direction, and the object to be processed on the rocking rack 51. There is no width equal to the full width of the.

In the dust collecting chamber 68 of the combine constructed as described above, the selectability of the processed objects is good on the left side in the traveling direction where the cross flow fan 91 is present, but the selectability of the processed objects is relatively poor on the right side in the traveling direction. .

As a countermeasure, the following means (1) to (3) can be used. (1) As shown in the side view of the threshing apparatus of FIG. 11 (a), a dust rack 107 is mounted on the rocking shelf 51, and a plurality of straw racks 1 arranged in parallel on the dust rack 107.
08 is inclined to the left as it goes backward in the traveling direction.

In this case, the straw discharged from the rear part of the handling cylinder 69 is received by the dust removal rack 107 attached to the swing shelf 51,
It is sent to the rear, but at this time, a plurality of straw racks 108 arranged in parallel on the dust removal rack 107 are inclined toward the left side in the traveling direction toward the rear side, and the straw debris can be guided to the left side where the sorting wind is strong. .

(2) As shown in FIGS. 11 (a) and 11 (b), a plurality of guides 109 arranged in parallel are provided at the rear end of the first shelf edge 101a on the lower surface of the first shelf plate 64, The sorting wind is directed to the left in the traveling direction by the inclination of the shelf guide 109.

(3) As shown in the view seen from the front side of the threshing device of FIG.
The diameter of 9a is increased on the right side in the traveling direction and decreased on the left side.
In FIG. 12 (a), there are two Kara Tan fans 79a having different diameters,
An example in which 79a is provided is shown, and FIG. 12B shows a configuration in which the diameter of a single Karatsuo fan 79a is made smaller in the continuous direction toward the left side in the traveling direction. By changing the diameter of the sardines in this way, it is possible to strengthen the sorting air on the right side in the traveling direction without the cross-flow fan 91 and to make the sorting air uniform.

According to the above methods (1) to (3), the dust collecting chamber 6 of the combine without the cross flow fan 91 is arranged.
It is possible to improve the selection property of the object to be processed on the right side in the traveling direction of 8 as compared with the related art.

When a plurality of dust racks 107 arranged in parallel and a straw rack 108 are provided on the rocking rack 51, the rocking rack assay is assembled to the combine or the rocking rack from the combine. When removing the assay, the dust removal rack 107 becomes an obstacle, and the rocking shelf assay cannot be assembled or removed.

Therefore, FIG. 13 (FIG. 13A shows the swing shelf 5).
As shown in a perspective view of one portion and a plan view of the swing shelf 51 portion of FIG. 13B, the feed chain 14 portion is configured to be openable and closable, and when the feed chain 14 portion is opened,
The dust removal rack 107 can be attached to both wall surfaces of the swing shelf 51.

Here, it is desirable that the dust removal rack 107 is screwed to both side wall surfaces of the swing shelf 51, and then the feed chain 14 portion is closed. Further, when removing the dust rack 107 from the swing shelf 51, the feed chain 14 is opened and the dust rack 107 is removed from the swing shelf 51.

In this way, the dust rack 107 can be easily attached to or separated from the combine body.

The grain in the Glen tank 30 is a vertical auger 18.
The discharge auger discharge port including the horizontal auger 19 is discharged to the outside of the combine 1. However, as shown in FIG. 14, it is known that the discharge auger can be operated by remote control (up / down, turning, expansion / contraction). If a configuration is used in which the direction in which the discharge auger turns is notified to the pilot seat 20 by the remote control operation, the operability of discharging the grain is improved.

That is, as shown in FIG. 14, the lamp 11 for indicating the movement in either the left direction or the right direction.
0 and 110 were provided on both sides at the tip of the discharge auger.
The lamps 110, 110 are provided at the tip end position of the discharge auger that can be visually recognized both when the lamp mounting position is operated by a remote controller outside the combine and when the operator operates the cockpit 20.

Therefore, by operating the left or right switch of the remote controller 111, the predetermined lamps 110, 110 on the inside or outside of the tip of the discharge auger turn on or blink to inform the turning direction of the discharge auger. Further, since the turning direction of either the left or right can be known at a glance, and the turning direction can be notified when the discharge auger is operated from the front or the rear of the machine body, there is no danger.

The lamp 110 may also be used as an alarm lamp for the amount of grains filled in a loading platform such as a truck by lighting when the grain sensor in the tank 30 is detected when the grains are full in the tank 30.

In a combine in which the Glen tank 30 is openable / closable, if the engine is still driven when the Glen tank 30 is opened, the belt for driving the grain-raising spiral 112 from the Glen tank 30 which is driven by the engine is driven. Since 113 remains in operation, and the operator can access the portion on the spiral drive belt 113 when the Glen tank 30 is opened, it is dangerous.

Therefore, the following structure can be adopted so that the driving of the engine is always stopped when the Glen tank 30 is opened.

That is, as shown in the plan view of the Glen tank portion in FIG. 15, a cover 115 is provided around the belt 113 for driving the spiral spiral 112 for auger grain elimination,
The structure is such that the gren tank 30 cannot be opened unless the gover 115 is opened, and the limit switch 114 is turned off and the engine is stopped when the cover 115 is opened.

As described above, when the Glen tank 30 is opened, it is necessary to open the cover 115 that covers the belt 113. When the belt 113 is removed, the engine is automatically stopped and the safety is improved.

As shown in the side view of the inside of the grain tank 30 of FIG. 16A and the sectional view of the inside of the grain tank 30 of FIG. 16B, the grains in the grain tank 30 are discharged. By installing the vibration motor 116 in the vicinity of the wall surface of the grain tank 30 in which the grain remains until the end when the grain discharge is completed, the grain can be completely discharged.

At this time, a plurality of paddy sensors 117 for detecting the grain storage position in the grain tank 30 are attached in the vertical direction of the inner wall surface of the tank 30, and when the grain is discharged, the bottom paddy sensor 117 stores the grain. It is desirable to activate the vibration motor 116 when it senses that the quantity has decreased.

The reason is that when the grains in the grain tank 30 are full, even if the tank side wall is vibrated by the vibration motor 116, the grains have little effect of moving to the outlet of the grain tank 30. It is effective to drive the vibration motor 116 only after the amount decreases.

Therefore, the vibration motor 116 is operated only when the grain discharge lever (not shown) of the cockpit 20 is "ON" and only the paddy sensor 117 on the lowermost side of the Glen tank is "OFF".

As described above, since the vibration motor 116 is activated only when it can exert its effect and is not activated when it is not needed, trouble is unlikely to occur and the durability of the motor 116 is improved.

In addition, the grain sensor 117 is provided at the bottom of the tank 30 to feed the grain 112, and the paddle sensor 117 is provided near the end of the grain when the grain is discharged. The last grain is Glen Tank 2.
When discharged from 0, the paddy sensor 117 is turned from on to off, and after detecting the end of discharging, the discharge tension belt 113 that drives the grain discharging spiral 112 can be turned off after a lapse of a certain time.

As a result, the lamp 110 attached to the tip of the discharge auger blinks to notify the operator that the discharge of the grains in the grain tank 30 is completed, and also for the grain discharge spiral drive. After the discharge tension belt 113 is turned off, the discharge auger may be automatically stored in the auger receiving portion of the combine after a while.

In this way, the operator can recognize the end of the grain discharge, and the operation is performed only at the start of the grain discharge, and thereafter the combine does not have to be operated until the end of the grain discharge.
