Moreover, since the tine penetrates the cover, the cover can be positioned 26 firmly to some extent. Thus, if the present invention is used, the support portion of the tine can be covered firmly and stably by the cover. Accordingly, with the present invention, it is possible to efficiently prevent grain culms from being caught or entangled on the support portion of the tine.
In the present invention, it is preferable that a through-hole or an slit is formed in the cover, and the tine penetrates the through-hole or the slit.

In the present invention, it is preferable that the cover is attached to . the support bar at, a position different from that of the tine in the longitudinal direction of the support bar.
According to this configuration, the cover is supported not only by the tines, but also by the support bar, and thus the cover is firmly supported.
Also, according to this configuration, the cover is attached to the support bar at a position different from that of the tine in the longitudinal direction of the support bar. Accordingly, the tine is not likely to interfere when the cover is attached to the support bar.
In the present invention, it is preferable that a first bar to which a plurality of the tines are attached in alignment in a first arrangement with unequal intervals therebetween, and a second bar to which a plurality of the tines are attached in alignment in a second arrangement that is the inverse of the first arrangement are provided as the support bars.
According to this configuration, the first arrangement of tines on the first bar and the second arrangement of tines on the second bar are inverse to each other, and therefore the cover covering the support portions of the tines mounted on the first bar can also be mounted on the second bar if used in the inverse direction. That is to say, a cover with the same structure can be used on the first bar and on the second bar. Accordingly, when this 36 configuration is used, the number of types of covers can be reduced and the cost can be reduced compared to the case of using dedicated covers for all of the support bars.

The present invention relates to a combine. =X =
Sw
[1] There have been conventional combines in which a grain storage = hopper that stores grain obtained by threshing is provided and a support = frame for supporting both the front and rear sides of the grain storage hopper Eh is constituted by bonding two rectangular pipe-shaped vertical frame bodies that extend in a vertical direction and a rectangular pipe-shaped lateral frame body that extends in the machine body lateral direction. In other words, a configuration has been used in which the two vertical frame bodies . are provided in a fixed and standing manner on the machine body frame with an interval therebetween in the body lateral direction, and the lateral frame body 1s provided such that it is connected and fixed to the upper portions of the two vertical frame bodies (e.g., see Patent Document 1).
[2] For example, Patent Document 2 discloses an example of a conventional whole-culm feeding combine. In the whole-culm feeding combine disclosed in Patent Document 2, a raking reel includes left and right reel frames, a support bar provided across the left and right reel frames, and tines attached to the support bar. With this kind of whole-culm feeding combine, when the raking reel is rotated during reaping work, the tines attached to the support bar pull up grain culm grown in a field and rake it toward the rear of the machine body.
[8] For example, a normal combine (a whole-culm feeding combine) disclosed in Patent Document 3 is already known as a normal combine such as that described above. In the normal combine disclosed in Patent
Document 8, a left-right-oriented input shaft (corresponds to a “reaping input shaft” in the document) that receives input of power is provided in a feeder.
With the normal combine disclosed in Patent Document 3, when power is transmitted to the input shaft via a forward rotation clutch, the input shaft 36 rotates in a forward direction, and when power is transmitted to the input shaft via a reverse rotation clutch, the input shaft rotates in a reverse constituted by merely providing the plate spring.
In the present invention, it is preferable that a support portion that - supports the tool is provided in addition to the storage portion on a side - toward the driving portion of the feeder case. -
According to this configuration, when the tool is stored in the storage = portion, 1t is supported by two locations, namely the storage portion and the ~ support portion, and therefore the storage orientation of the tool is stable. o
Accordingly, when the tool is stored in the storage portion, the tool does not - unexpectedly fall out, even if the feeder is driven. =
In the present invention, it is preferable that the support portion is . pin that can be inserted into a hole formed in the tool. -
According to this configuration, the support portion can be easily constituted by merely providing a pin that can be inserted into a hole formed in the tool.
In the present invention, it is preferable that a reinforcing channel member that extends in a direction orthogonal to a conveying direction of the feeder in side view is connected to the side toward the driving portion of the feeder case so as to open laterally outward, and the plate spring is provided in ! the opening of the channel member.
According to this configuration, the plate spring can be compactly attached to the side toward the driving portion of the feeder case by providing the plate spring in the opening of the channel member.

As described above, the motor portion 6 is provided below the driver’s seat 9, and since the position of the driver's seat 9 is higher, a floor portion 5A of the driving portion 5 is accordingly provided at a high position as well. In view of this, as shown in Figs. 4, 6, and 7, the machine body frame 4 includes a floor portion 5A that is at a location below the driving portion and is located higher than the other locations by a predetermined amount.
As shown in Figs. 3 and 4, the machine body frame 4 is configured to include a left and right pair of rectangular cylindrical main frame portions 4A that extend along the front-rear direction, a grid-shaped frame portion 4B that is supported by the upper portion of the main frame portion 4A, and a raised frame portion 4C for configuring the floor portion 5A such that it is located higher than the other locations by a predetermined amount at a location below the driving portion 5. The grid-shaped frame portion 4B is constituted by connecting multiple front-rear-oriented frame bodies 28 and multiple lateral frame bodies 29 in a grid shape. 3b As shown in Figs. 6 and 7, at a corresponding location below the driving portion 5, the raised frame portion 4C is configured to include a pair of left and right vertical plate members 30R and 30L that are provided - standing in a vertical orientation upward past the grid-shaped frame portion = 4B, and a pair of front and rear lateral support members 31 that connect the = upper ends of the left and right vertical plate members 30R and 30L. i

and are formed in an inclined orientation that is inclined such that the edges on the machine body outer side (right side) are located farther from the edges - on the machine body inner side (left side) the farther downward they are = located.
The lower connecting plate 36 is such that the ends of a band-shaped plate member are bent in the same direction and connected to the lower ends of the front and rear support plates 35 so as to span across them in a loop fe shape, and thus an intermediate linear route portion 36a extending in the = machine body front-rear direction forms a first foothold. The linear route = portion 36a of the lower connecting plate 36 is located more toward the » machine body outer side than the lower ends of the support plates 35, is ol about the same height as the grid-shaped frame portion 4B, and is easy for the driver to place his or her foot on when getting into the driving portion 5 from the ground. Uneven portions 38 for preventing slipping are formed on the linear route portion 36a of the lower connection plate 36. , The upper connection plate 37 is connected to and, spans between the front and rear support plates 35 while being bent in an approximate L shape in a view in the front-rear direction so as to conform to a region constituted by the upper edges and a portion of the upper ends of the edges on the machine body outer side (right side) of the front and rear support plates 35.
A horizontal surface 37a on an upper side corresponding to the upper edges of the support plates 35 on the upper connecting plate 37 is located at approximately the same height as the floor portion 5A of the driving portion 5 while being aligned outward from the machine body right side of the floor portion 5A of the driving portion 5. A second foothold is formed by the horizontal surface 37a on the upper side.

Problem to be Solved by the Invention
[1] Problems corresponding to Background Art [1] are as follows.
With the above-described conventional configuration, when ~ fabricating the support frame for supporting the grain storage hopper, the two rectangular pipe-shaped vertical frame bodies and the rectangular . pipe-shaped lateral frame body.need to be integrally connected and fixed by _ being bonded using welding, for example. That is to say, the edges of the rectangular pipe-shaped vertical frame members are welded while in contact with the side surface of the rectangular pipe-shaped lateral frame member.
This kind of process is disadvantageous in that it is time-consuming, and accordingly, the fabrication of the support frame is time-consuming, and an increase in cost is incurred.
It is an object of the present invention to provide a combine according to which the manufacturing step can be simplified and a lower cost can be achieved.
[2] Problems corresponding to Background Art [2] are as follows.
However, with the conventional whole-culm feeding combine, during reaping work, in particular, there is a risk that standing grain culms will be torn off by being caught on the support portions of the tines on the support bar, and cut grain culms will be caught on and entangled on the support portion, causing them to become entrained, thereby inhibiting the conveying of cut grain culms that were cut normally, whereby the conveying efficiency decreases.
In view of such circumstances, provision of a whole-culm feeding combine capable of efficiently preventing grain culms from being caught on the support portions of the tines on the support bar is desired.
support state in which only the base end is supported, and as a result, 1s o prevented from becoming a hindrance when operating the key switch 50 or i, viewing the warning lamp 51. Also, the arm rest 45 1s such that the hand = rest operation portion 45b is located near the rear side of the control oo operation lever 52 and can be used as a support platform for resting and po supporting a hand operating the control operation lever 52. tt
As shown in Fig. 17, a reel elevation operation lever 53 is provided so = as to extend upward through a guide hole 54 formed on the right end of the = front panel 26. Also, as shown in Fig. 18, the reel elevation operation lever = 53 is configured in an inclined shape that is located more to the right the - further up it is, such that a gripping portion 53A on the upper end thereof ~ protrudes outward and to the right more than the right end of the control column 25 does.
The vertically-extending portion 45a of the armrest 45 is located near the rear side of the location at which the reel elevation operation lever 53 is inserted into the panel. As described above, the reel elevation operation lever 53 inclines more toward the right the further upward it is, and in front view, the gripping portion 53A is located outward and to the right more than the armrest 45 is. By using such a configuration, the reel elevation operation lever 53 can be operated preferably with no risk of the operation being inhibited by the armrest 45.
As shown in Fig. 2, a main gear shift lever 55 for performing a gear shift operation of a main gear shifting apparatus (not shown) provided in a travel driving system, a sub-gear shift lever 56 for performing a gear shift operation of a sub-gear shifting apparatus (not shown) provided in a travel driving system, a cutting clutch lever 57 for switching on and off transmission of power to the cutting conveying apparatus 2, a threshing clutch lever 58 for switching on and off transmission of power to the threshing apparatus 7, and the like are provided on the side panel 27.

The upper surface 60 of the engine hood 59 is provided at approximately the same height as the side panel 27 while being continuous in a lateral direction. Also, the upper surface 60, the front surface 61, and the 36 rear surface 62 of the engine hood 59 are enclosed by a plate body, but the right side of the engine hood 59 is open in order to take in external air for cooling the engine, and the left side thereof is open in order to discharge - exhaust air resulting from cooling. ,
An air suction dust-proof cover 64 that includes a dust-proofing net 63 x for air suction using external air as engine cooling air is provided on the right - side of the engine hood 59. A radiator 65 for cooling the engine 11 using the external air is provided at a location facing the air suction dust-proof cover 64 = in the motor portion 6. The air suction dust-proof cover 64 is integrally x connected to the engine hood 59.
As shown in Fig. 2, the outward end of the air suction dust-proof ~ cover 64 is located on the rightmost side of the entire machine body, and the . mounting step portion 34 is provided in a state of being located more inward = in the machine body lateral width direction than the right end of the air suction dust-proof cover 64 is. Note that Fig. 2 shows a state in which a later-described auxiliary step 163 juts outward, but during non-work, the auxiliary step 163 is stored on the machine body inner side, and therefore it is located more inwardly in the machine body lateral width direction than the . right end of the air suction dust-proof portion 64 is.
The ‘engine hood 59 is supported by the machine body frame 4 swingably about a machine body front-rear-oriented axis P3, along with the air suction dust-proof cover 64 and the driver’s seat 9. That is to say, as shown in Fig. 4 and Figs. 11 to 13, at two separate locations in the front-rear direction, which are on the lower end on the machine body outward side of the engine hood 59, a fulcrum bracket 66 fixed to the machine body frame 4, and a support arm 18 extending from the lower end of the engine hood 59 are connected so as to pivot swingably about a front-rear-oriented fulcrum pin 67 located on the same axis P3. Also, the engine hood 59 is configured to be able to switch between a closed state in which the engine 11 is covered over (state indicated by solid line in Fig. 13), and an open state in which the engine 11 is open (state indicated by virtual line in Fig. 13) by being swung about the machine body front-rear-oriented axis using the front and rear fulcrum pins 67.
The position of the engine hood 59 can be held in the closed state by a locking mechanism 68 with a known structure according to which it is possible to switch between a locked state and an unlocked state by swinging a 36 lever, and in a normal working state, the engine hood 59 is kept in the closed state. Also, in the case of maintenance work such as inspection of the engine
11 and members related thereto, maintenance work is more easily performed by removing the held state of the locking mechanism 68 so as to switch to the =O open state. a.

Thereafter, the fuel is supplied to a fuel injection pump 180 provided near the engine 11, and is supplied to a combustion chamber (not shown) of the engine 11 by an injection nozzle 181.
Most of the supplied fuel is consumed by the engine 11, but remaining fuel that is not used is returned to the fuel tank 170 from the injection nozzle 181 through a fuel return tube 182.
Also, an air vent pipe 183 for removing air in the fuel tank 170 is provided in order to prevent the inside of the fuel tank 170 from decompressing accompanying the suction of fuel by the fuel pump 176. The air vent pipe 183 is composed of a flexible material such as rubber or soft synthetic resin, for example, and is provided such that one end thereof is in 36 communication with the internal space of the fuel tank 170, and the other end thereof is continuous with the external space.

In the present invention, it is preferable that an intermediate \ :
CL - “extending portion is provided that is connected to an intermediate portion in : the longitudinal direction of the laterally extending portion and extendsina | - vertical direction, the lower end of which being supported by the machine / = body frame. oo
According to this configuration, an intermediate extending portion © that extends in a vertical direction is provided at an intermediate portion in the longitudinal direction of the laterally extending portion, and the lower end of the intermediate extending portion is supported by the machine body frame. Thus, due to the fact that the intermediate extending portion is , provided, even. if a configuration is used in which the weight of the grain . storage hopper is supported by the intermediate portion in the longitudinal direction of the laterally extending portion, the weight can be supported by : the intermediate extending portion and the burden of the weight on the laterally extending portion can be lightened. oo
In the present invention, it is preferable that a reinforcement member that is connected over the laterally extending portion and the vertically extending portion is provided at a bent portion at which the laterally extending portion and the vertically extending portion are continuous in an approximate L shape.
According to this configuration, since a reinforcement member is provided at a bent portion at which the laterally extending portion and the vertically extending portion are continuous in an approximate L shape, downward warping of the laterally extending portion caused by the weight of the grain storage hopper can be suppressed to a minimum, and an improvement in the durability of the hopper support frame can be achieved.
In the present invention, it is preferable that a front and rear pair of the hopper support frames are provided so as to support the front side and rear side of the grain storage hopper.
According to this configuration, since the front side and rear side of the grain storage hopper are supported by the hopper support frames, the

Also, a work platform 187 for performing various types of work is constituted by the ‘ location formed in the flat surface.
That is to say, when performing fuel supply work for supplying fuel to the fuel tank 170, a fuel storing container (not shown) in which the fuel to be supplied is stored can be mounted and supported by the work platform 187 formed in the flat surface of the upper surface 170a of the fuel tank 170. By using the work platform 187 as a fuel container mounting platform in this manner, fuel supplying work can be performed easily and efficiently.
Also, when the cap 94B of the grain storage hopper 94 is removed or 256 the upper portion of the threshing apparatus 7 is opened to perform maintenance work such as cleaning, the work can be performed by a worker getting on the work platform 187 formed on the upper surface 170a of the fuel tank 170.

That is to say, a communication path 194 that allows the internal space to be in communication with the outside is formed in the machine body frame 4 to which the lower end of the vertically extending portion 140B is connected.
That is to say, the plate-shaped attachment body 195 is fixed by connection to the lower end of the vertically extending portion 140B as well, similarly to the end toward the threshing apparatus 7 of the laterally extending portion 140A, and the attachment body 195 is connected by bolting 36 to the machine body frame 4. Also, a through-hole 196 is formed in the attachment body 195 so as to be continuous with the internal space thereof, a through-hole 197 that penetrates in the vertical direction and opens - downward is formed at a location continuous with the through-hole 196 in the =o machine body frame 4, and the communication path 194 that allows it to be = in communication with the outside is constituted by the through-hole 197. {x
By using such a configuration, if fuel is supplied using the operation ps of the fuel pump 176, external air is suctioned from the end toward the = threshing apparatus 7 side of the laterally extending portion 140A and the = lower end of the vertically extending portion 140B and is supplied into the - fuel tank 170, and therefore fuel supply is performed favorably. The o above-described communication paths 189 and 194 are opened laterally or o downward, and there is little risk of dust or water such as rainwater =k entering.
As shown in Fig. 10, the connected portion 188 is provided at a position near the intermediate support column 143 of the laterally extending portion 140A, and the connected portion 198 on the fuel tank 170 side at which the air vent pipe. 183 is connected is formed at a location near the . intermediate support column 143 on the upper surface of the fuel tank 170.
Also, the air vent pipe 183 is provided so as to extend upward along the intermediate support column 143, and a holding member 199 that holds the air vent pipe 183 to the intermediate support column 143 in an orientation : extending upward is provided.

The fuel 36 gauge 200 is constituted by a clear tube whose upper and lower sides are in communication with the inside of the tank, and can indicate a fuel storage amount using a fuel level that is the same height as the fuel level inside the ~ fuel tank 170. =
The water separator 178, the oil filter 179, and the fuel gauge 200 are ~ provided so as to be located between the fuel tank 170 and the side wall 7A of B the threshing apparatus 7. Thus, by equipping these elements in a narrow = space sandwiched between the fuel tank 170 and the threshing apparatus 7, ~ for example, there is little risk that a large-capacity storage bag F that has ow performed bagging and collecting will come into contact therewith, or that a = malfunction will occur due to a foreign object interfering therewith. oO =

The hydraulic cylinder 334 is attached between the arm 332 and the cutting frame 319, and the raking reel 320 swings up and down due to the expansion/contraction of the hydraulic cylinder 334. A driving mechanism 335 that causes the raking reel 320 to rotate is provided on the lateral outer side of the raking reel 320. Adriving cover 336 that covers the driving mechanism 335 is provided on the lateral outer side of the driving mechanism 335.
The raking reel 320 includes left and right reel frames 337, four support bars 339 that are provided across the left and right reel frames 337, and multiple tines 340 that are attached to the support bars 339. The four support bars 339 are in the form of hollow pipes, and are provided so as to span between the left and right reel frames 337. The four support bars 339
EE ——————————————————————————————————— eee eee are provided with equal intervals therebetween in the circumferential - direction of the reel frame 337. -
Tines v
The tines 340 are constituted by a linear metallic material or resin ~ material, and as shown in Fig. 36, they are attached in alignment to the - support bars 339 with intervals therebetween in the longitudinal direction of = the support bars 339, at positions away from the fingers 324 of the auger 322. I
In the present embodiment, nine attachment holes 342 are formed in each - support bar 339. In correspondence to this, multiple attachment holes 342 LT are formed in the support bars 339. As shown in Figs. 36 to 40, the tines 340 - are supported by being attached to the support bars at support portions 343.
The support portions 343 are portions at which the tines 340 are in close contact with the support bars 339. An attached portion 340B is formed as a portion of the support portion 343 on each tine 340. The attached portions . 340B are formed into “U” shapes. When fastening members such as bolts 344 are inserted into the “U” grooves, the bolts 344 are fastened to the attachment holes 342, the attached portions 340B are sandwiched between the heads of the bolts 344 and the support bars 339, and the tines 340 are fixed in a supported manner to the support bars 339.
As shown in Fig. 38, the tines 340 each include a helical spring portion 345 at an intermediate site in a direction from the leading end 340A of the tine 340 to the support portion 343. The number of windings of the spring portion 345 is assumed to be two, for example. The tines 340 each include a bent portion 346 downward of the spring portion 345. The tines 340 are bent such that the portions below the bent portions 346 are directed rearward in an elbow shape.
Hump cover
As shown in Figs. 36 to 41, hump covers 341 (correspond to “covers”) that cover the support portions 343 of the tines 340 on the support bars 339 are provided. The hump covers 341 are flexible and formed as rectangular sheets whose direction in the longitudinal direction of the support bar 339 is used as the long side, and one is provided per support bar 339. The hump 36 covers 341 are formed with a length that covers approximately the entire length in the longitudinal direction of the support bar 339. Multiple circular through-holes 347 that correspond to the cross-sectional shape of the tines > 340 are formed in the hump covers 341. The tines 340 penetrate the - through-holes 347 of the hump covers 341. In other words, one tine 340 - penetrates one through hole 347. In the present embodiment, nine through . holes 347 are formed in each hump cover 341. The cross-sectional area of - each through-hole 347 is formed so as to be greater than the cross-sectional = area of each tine 340, and thus it is easy for the tines 340 to pass through the Io through holes 347. or
Also, as shown in Figs. 36, and 39 to 41, multiple fixing holes 348 are = formed in the hump covers 341. In the present embodiment, five fixing holes o 348 are formed in each hump cover 341. The two fixing holes 348 on the left - and right ends are formed at the same positions as the two through holes 347 on the left and right ends in the longitudinal direction of each hump cover 341. Also, the other three fixing holes 348 are formed at positions different from those of the through-holes 347 (positions different from those of the . tines 340) in the longitudinal direction of the hump cover 341, and specifically, they are formed at central sites at intermediate positions sandwiching two through-holes 347.
In order to enable the hump cover 341 to be attached to the support bar 339 side using a fixing tool such as a bundling band 349, the fixing holes 348 are formed in the hump cover 341. First, the bundling bands 349 are inserted into the fixing holes 348 in order to use the fixing holes 348 to attach the hump cover 341 to the support bar 339 side with the bundling bands 349.
Then, when the bundling band 349 has been inserted into the fixing hole 348, the bundling band 349 is fastened by being wrapped once around the support bar 339. Accordingly, the hump covers 341 are fixed by being in close contact with the support bars 339 at the sites of the fixing holes 348. Thus, for all of the fixing holes 348, fixing of the hump covers 341 to the support bars 339 is achieved using a fixing tool such as a bundling band 349.
In this way, the support portions 343 of all of the tines 340 are covered by a single hump cover 341. Also, the tines 340 penetrate the hump cover 341 at positions below the spring portions 345, and when attached to the tines 340, the site of the hump cover 341 below the through-holes 347 is located on the front side of the tines 340. That is to say, the rearward sides 36 of the support portions 343 of the tines 340, and the rearward and lower sides of the spring portions 345 are covered by the hump cover 341. b7
EE —————————————————————————————————————————— re eee ___
Since one hump cover 341 is used for one support bar 339, the support om portions 343 of two or more tines 340 are covered by a single hump cover 341. LL
Furthermore, the support portions 343 of all of the tines 340 are covered by a we single hump cover 341. = os
Support bar -
Also, a first bar 350 to which multiple tines 340 are attached in - alignment in a first arrangement with unequal intervals therebetween, and a - second bar 351, to which multiple tines 340 are attached in alignment in a = second arrangement that is the inverse of the first arrangement, are provided - as the support bars 339. The first bars 350 and the second bars 351 are 2 disposed alternatingly adjacent to one another in the circumferential direction of the reel frame 337. That is to say, the raking reel 320 of the present embodiment includes four support bars 339 composed of two types, namely two first bars 350 and two second bars 351. The arrangement of the » through-holes 347 in the hump covers 341 is in conformity with the first arrangement. That is to say, if the hump covers 341 are used with left and right reversed, the arrangement of the through-holes 347 will be in conformity with the second arrangement, which is the inverse of the first arrangement. That is to say, a hump cover 341 with the same configuration can be used for both the first bar 350 and the second bar 351.
Side divider
As described above, as shown in Figs. 34, 42, and 43, a driving cover 336 that covers the driving mechanism 335 is provided on the left lateral outer side of the driving mechanism 335 of the raking reel 320. Also, a side cover 325 that covers the driving mechanism 322A of the auger 322 is provided on the left lateral outer side of the cutting frame 319. In side view of the machine body left side, a space S between the driving cover 336 and the side cover 325 gets smaller as the second fulcrum X2 is approached. For this reason, during reaping work, there is a risk that the heads of the standing grain culms that have not yet been cut will enter the space S, get jammed between the driving cover 336 and the side cover 325, and be torn off, thus preventing conveying of the cut grain culms that were cut correctly. 3b In view of this, a side divider 326 that prevents the standing grain culms on the uncut side from entering the space S is provided. The side grain storage hopper can be stably supported, and moreover, it 1s possible to wr achieve an even lower cost by simplifying the step of manufacturing the front » and rear hopper support frames. =
In the present invention, it is preferable that an intermediate we extending portion that is connected to an intermediate portion in a longitudinal direction of the laterally extending portion and extends in a = vertical direction, the lower end of which being supported by the machine - frame, is provided on each of the front and rear hopper support frames, and = a bag support tool that supports a storage bag for bagging grain from ® the grain storage hopper is provided such that it spans between and is o supported by the front and rear intermediate extending portions.
According to this configuration, an intermediate extending portion that extends in a vertical direction, the lower end of which being supported by the machine body frame, is provided on each of the front and rear hopper support frames, and therefore the weight of the grain storage hopper can be supported by the front and rear intermediate extending portions, and thus . the burden of the weight on the laterally extending portion can be lightened.
Also, the bag support tool for supporting the storage bag for grain collection spans between and is supported by the front and rear intermediate extending portions. Thus, by using the intermediate extending portions provided on both the front and rear hopper support frames, the front and rear sides of the bag support tool can be stably supported.
In the present invention, it is preferable that the bag support tool is supported such that its position in the vertical direction can be changed and adjusted.
According to this configuration, by changing and adjusting the position in the vertical direction of the bag support tool, the vertical height of the storage bag for grain collection can be changed such that collection work is easier to perform, which improves handleability.
In the present invention, it is preferable that an auxiliary step for worker mounting is provided so as to be located laterally outward of the machine body in the grain collecting portion, and an auxiliary sun shielding portion that covers over the auxiliary step is provided so as to be supported by the hopper support frames.
According to this configuration, an auxiliary worker who performs work of bagging grain from the grain storage hopper into storage bags, work divider 326 is fixed to the cutting frame 319 50 as to be located more on the - machine body outer side than the side cover 325 and the driving cover 336 ow are, and closes off the space S appropriately. =
The side divider 326 includes a bar-shaped guide member 352 that x extends rearward and upward, and a bar-shaped L. member 353 that is bent os into an “L” shape. The lower end of the guide member 352 is connected to = the front end of the left cutting frame 319. On the guide member 352, one end of the L member 353 is connected to an intermediate site located from the ~ lower end side to the upper end side. &
When the raking reel 320 is at least at a normal cutting position, the - guide member 352 is extended so as to traverse the space S from the left - cutting frame 319 and reach a position on the left lateral outer side of the driving cover 336. Also, the guide member 352 is inclined so as to move further from the lateral outer side on the left side of the machine body as the upper end is approached from the lower end. . The L member 353 includes a vertical site that is connected to an . intermediate site of the guide member 352 and extends rearward in a rearward and downward inclined state, and a lateral site that is bent inward of the machine body from the vertical site, the end of which being connected to the left surface of the machine body frame 314.
With this kind of side divider 326, during reaping work, the uncut grain culms located on the machine body left side are guided by the guide member 352 so as to be separated to the machine body outer side. Thus, the heads of the uncut grain culms are not likely to enter the space S.
Accordingly, cases in which disturbances in the conveyance of the cut grain culms in the cutting portion 313 or the like occur are also reduced. Also, since the side divider 326 has a simple construction combining the bar-shaped guide member 352 and the L member 353, increases in the cost can be suppressed to a minimum, and the field of view of an operator from the driving operation portion 317 to the machine body left side is not blocked.
Dividing rod
As shown in Figs. 34, 42, and 43, the side cover 325 swells the most laterally left outward of the machine body near the bottom. During reaping 36 work, a dividing rod 327 that prevents the standing grain culms from colliding with a swelling portion 325A is attached to the cutting frame 319.
EE ——— EE E——
The dividing rod 327 guides the standing grain culms further outward of the = machine body than the cutting frame 319, and the dividing rod 327 includes a ¥ connecting member 354 and a guiding member 355. The connecting member 354 is a horizontal plate, and the internal end is bonded at a lower position = on the rear portion of the left surface of the left cutting frame 319. The i guide member 355 is a bar-shaped member that is formed to be longer in the - front-rear direction, and an intermediate site thereof is connected to the outer = end of the connecting member 354. The guide member 355 is configured to - be located more outward of the machine body as the rear is approached from = the front, and the rear end thereof extends to the vicinity of the front end of 0 the swelling portion 325A.
According to this kind of dividing rod 327, when performing reaping work, the uncut grain culms are guided more outward of the machine body than the swelling portion 325A by the guide member 355. Accordingly, the uncut grain culms are prevented from colliding with the swelling portion 325A. . . . }
Alternative embodiment to third embodiment (1) In the above-described embodiment, an example was given in which multiple through-holes 347 are formed in the hump covers 341, but there is no limitation to this. For example, as shown in Fig. 44, nine lateral dash-shaped slits 356 may be formed in the hump cover 341 instead of the through-holes 347. In such a case, the corresponding tines 340 penetrate the slits 356. 26 By causing the tines 340 to penetrate the slits 356 in the hump covers 341 in this manner, the tines 340 are held in the slits 356 due to the flexibility of the hump covers 341. For this reason, the positions of the hump covers 341 can be stably held with respect to the tines 340. In this case, the shape of the slits 356 is not limited to being a lateral dash shape as shown in
Fig. 44, and may be various shapes such as a vertical dash shape or a cross shape. Also, it is preferable that the slits 356 are limited to being located in the hump covers 341 without extending to the ends of the hump covers 341.
Also, although this is not particularly shown in the drawings, the through-holes 347 and the slits 356 may be formed in the hump cover 341 36 and the corresponding tines 340 may penetrate both the through-holes 347 and the slits 366.

Furthermore, in the above-described embodiment, the cross-sectional area of the through-holes 347 was formed to be larger than the cross-sectional rs area of the tines 340, but there is no limitation to this. For example, the - cross-sectional area of the through-holes 347 may be formed to be smaller be than the cross-sectional area of the tines 340, and in such a case, the tines — 340 are held more reliably in the through-holes 347 due to the flexibility of o : the hump cover 341. = (2) In the above-described embodiment, an example was given in _ which, for example, nine through-holes 347 or slits 356 are formed in the ® hump cover 341, but there is no limitation to this. For example, the number of through-holes 347 or slits 356 may be one to eight, or 10 or more. In such = a case, the number of through-holes 347 or the slits 356 provided may be the same as the number of tines 340 or attachment holes 342, or more. (3) In the above-described embodiment, an example was given in which one tine 340 penetrates one through-hole 347, but there is no limitation to this. For example, two or more tines 340 may penetrate one through-hole 347. Also, the shape of the through-holes 347 is not limited to being circular, and may be a rectangular shape, a cocoon shape, a shape with an slit that exceeds the diameter of a hole in a diameter direction of one hole, a shape with an slit that is continuous in the diameter direction of two holes, or the like.

(5) In the above-described embodiment, an example was given in which the fixing holes 348 are formed in the hump cover 341, but there is no limitation to this. The fixing holes 348 need not be formed in particular, and for example, the hump covers 341 may be supported by the support bars 339 by the hump covers 341 being wrapped once around the support bars 339 and the upper ends of the hump covers 341 being bonded to a portion of the hump covers 341. (6) In the above-described embodiment, an example was given in which the support portions 343 of all of the tines 340 are covered by a single 36 hump cover 341, but there is no limitation to this. For example, the support portions 343 of all of the tines 340 may be covered by aligning two or more

Ny (7) In the above-described embodiment, the bundling bands 349 were - described as an example of a fixing tool, but there is no limitation to this, and x a fixing tool using a method of tying together a single string-shaped member fs may be used.
In such a case, the string-shaped members are inserted into = the fixing holes 348, are wrapped once around the support bars 339, and the ~ ends of the string-shaped members are tied together, whereby the hump - covers 341 are fixed to the support bars 339. = (8) In the above-described embodiment, a description was given in - which the number of windings of each spring portion 345 is two, for example, ol but there is no limitation to this.
The number of windings of the spring portion 345 may be one or three or more.

That is to say, for example, in the case where the raking reel 320 is formed into a shape other than a square (polygon with five angles or more) in side view and five or more support bars 339 are provided, for example, as the support bar 339, another bar with an arrangement of tines 340 that is completely different from those of the first bar 350 and the second bar 351 may be provided in addition to the first bar 350 and the second bar 351. Also, it is possible to include only multiple first bars 350 to which the tines 340 are attached in alignment in a first arrangement with unequal intervals as the support bar 339.

An operation nut 411 (corresponds to “operation portion” . in the present invention) is provided on the input shaft 410. The cut grain ~ culms are fed to the threshing apparatus 404 by the conveying chain 412 due o to the driving rotating body 409 and the driven rotating body 408 rotating. i
As shown in Figs. 46 and 47, a reinforcing channel member 417 is = connected to the right side of the feeder case 407 (side of the feeder case 407 = toward the driving portion 406). The channel member 417 extends in a direction orthogonal to the conveying direction (longitudinal direction) of the = feeder 405 in side view. The channel member 417 is connected by welding to - the right side of the feeder case 407 so as to open to the right lateral outer Se side. A later-described storage portion 419 in which a tool 418 can be stored is provided on the right side of the feeder case 407.
The tool 418 is a tool in the form of a spanner. Specifically, the tool 418 includes a mouth 430 and a handle 431. ‘ The mouth 430 is a portion that can be attached to the operation nut 411. In other words, as will be described later in detail, if the operation nut © 411 is constituted by a hexagonal nut, for example, the mouth 430 is formed into a shape that can be attached to a hexagonal nut. A plate 430a for reinforcing the mouth 430 is connected by welding in the opening portion of the mouth 430.
The handle 431 is constituted by a bar-shaped flat plate. The mouth 430 is connected by welding to the tip of the handle 431. A round hole 431a (corresponding to “hole” in the present invention) (see Fig. 49) is formed on the base of the handle 431.
As shown in Fig. 49, a left and right pair of boss portions 413 are provided on the rear end of the feeder case 407. The left and right pair of boss portions 413 protrude outward and laterally left and right from the left and right sides of the rear end of the feeder case 407. The left and right pair of boss portions 413 rotatably support the input shaft 410 via a left and right pair of bearings 414. The portions protruding outward laterally left and right of the left and right pair of boss portions 413 are supported swingably on a left and right pair of brackets 415. The left and right pair of brackets 415 are connected by bolts 416 to the front of the threshing apparatus 404.
The left end of the input shaft 410 (the end on the opposite side of the driving portion 406 of the input shaft 410) protrudes outward laterally to the left from the left boss portion 413 of the left and right pair of boss pertions v ’ 413. On the portion protruding outward laterally to the ieft of the left end of - the input shaft 410, an input pulley 420 and an output sprocket 421 are - provided in the stated order starting from the left. A belt 422 for relaying = power from a winnower 424 (see Fig. 45) provided in the threshing apparatus 404 to the input shaft 410 is wrapped around the input pulley 420. A chain B 423 for relaying power from the input shaft 410 to a cutting driving shaft 425 - (see Fig. 45) is wrapped around the output sprocket 421. -
The right end of the input shaft 410 (the end of the input shaft 410 ol toward the driving portion 406) protrudes outward laterally to the right from & the right boss portion 413 of the left and right pair of boss portions 413. =
Three steps 426, 427, and 428 whose diameters decrease the closer to the right end they are located (end in the axial direction of the input shaft 410) are formed on the right end of the input shaft 410. The three steps 426, 427, and 428 are constituted by a small diameter portion 426, an intermediate . diameter portion 427, and a large, diameter portion 428. .
The large diameter portion 428 is located the closest to the central portion (central portion of the input shaft 410) in the left-right direction (axis
X direction of the input shaft 410), or in other words, it is the step located the closest to the left end of the three steps 426, 427, and 428. The large diameter portion 428 has the largest diameter of the three steps 426, 427, and 428. The right bearing 414 of the left and right pair of bearings 414 that rotatably support the input shaft 410 is provided on the large diameter portion 428. The bearings 414 are positioned by retaining rings 414a in the 26 left-right direction.
Among the three steps 426, 427, an 428, the intermediate diameter portion 427 is the step between the small diameter portion 426 and the large diameter portion 428. The intermediate diameter portion 427 is formed into a portion that protrudes outward laterally to the right on the right end of the 80 input shaft 410. Among the three steps 426, 427, and 428, the intermediate diameter portion 427 has a diameter that is smaller than that of the large diameter portion 428 and is larger than that of the small diameter portion 426. The operation nut 411 is provided slidably in the left-right direction on the intermediate diameter portion 427. Specifically, the operation nut 411 36 has irregular engagement (e.g. key engagement) with the intermediate diameter portion 427. That is to say, the operation nut 411 is provided such
EEE ———————————————e erm that it cannot rotate relative to the input shaft 410. A key groove 427a is - formed in the intermediate diameter portion 427. o
The small diameter portion 426 is the smallest end in the left-right - direction of the three steps 426, 427, and 428, or in other words, it is the step 3 on the rightmost end. The small diameter portion 426 is formed on a portion = that protrudes outward laterally to the right on the right end of the input ~ shaft 410. The small diameter portion 426 has the smallest diameter of the = three steps 426, 427, and 428. A fastening nut 429 (corresponds to w= “fastening tool” in the present invention) is provided on the small diameter ol portion 426. Specifically, the fastening nut 429 is screwed into the small - : diameter portion 426. Screwing is carried out on the small diameter portion 426. The fastening nut 429 fastens the operation nut 411 in the left-right direction.
