As shown in FIGS. 12 to 14, the front-to-back frame 149 is a plate-like frame, and on the side of the front-to-back frame 149 opposite to the side where the threshing apparatus 104 is located in the short side, A bent portion 149a is formed in the front-rear direction. That is, the front-rear direction frame 149 is formed in an L shape in a cross-sectional view in the front-rear direction. Thereby, the rigidity of the front-rear direction frame 149 is enhanced by the bending portion 149a. Of the front-to-rear frame 149, the side where the threshing device 104 is positioned relative to the bent portion 149a is a horizontal surface, and bolt insertion holes are formed at both longitudinal end portions of the horizontal surface.

The bolt insertion holes corresponding to the bolt insertion holes of the front and rear direction frames 149 are also formed in each of the front side bracket 148A and the rear side bracket 148B, and the respective bolt insertion holes of the front side bracket 148A and the rear side bracket 148B and the front and rear direction frame The front and rear direction frames 149 and the front side brackets 148A are bolted together and the front and rear direction frames 149 and the rear side brackets 148B are bolted together in a state where the bolt insertion holes at the longitudinal direction end portions 149 are engaged. In this manner, the front-rear direction frame 149 connects the upper surface portions of the front side lateral frame 145A and the rear side lateral frame 145B to each other via the front side bracket 148A and the rear side bracket 148B.

A connecting frame 150 is welded and fixed to the lower surface of the horizontal surface of the front and rear intermediate portion of the front and rear facing frame 149 in the portion near the rear. The connection frame 150 is a plate-like frame that is faced to the lower surface of the horizontal surface of the front-to-back frame 149, and extends from the rear side of the front-to-back frame 149 toward the side on which the threshing device 104 is located And connects the rear wall of the threshing apparatus 104 to the rear end of the threshing apparatus 104 via the connection bracket 156. From this, in the state where the connection frame 150 is supported by the right side wall 104A, the front-rear direction frame 149 is mounted and supported on the upper surface portion of the connection frame 150. An inclined surface 150 a is formed on the side where the threshing device 104 is located than the longitudinal middle portion of the connection frame 150. In the connection frame 150, the area on the side where the inclined surface 150a is located is inclined so as to be positioned lower as it is farther from the front-rear direction frame 149. Further, in the connecting frame 150, the upper surface on the side where the front and back direction frame 149 is positioned than the inclined surface 150a is a horizontal horizontal surface 150b.

The connection bracket 156 and the inclined surface 150a are connected by welding. From this, the connection frame 150 and the connection bracket 156 are integrally formed. The connection bracket 156 is formed in a flange shape with respect to the inclined surface 150a, and the connection bracket 156 and the right side wall 104A are bolted to each other. Although the connection bracket 145 d is not shown in FIG. 14, the connection bracket 145 d is located on the front side of the vehicle relative to the connection bracket 156 in a state of overlapping with the connection bracket 156 in the front-rear direction. Further, the upper and lower positions of the bolt connection in the connection bracket 156 also substantially overlap with the upper and lower positions of the bolt connection in the connection bracket 145 d. The bolt connection portion of the connection bracket 156 is located outside the cross section of the inclined surface 150a, and can be easily bolted by an operator using an impact wrench or the like as in the connection bracket 145d.

The front-to-back frame is formed flush with the front-to-back frame by the configuration in which the front-to-back frame 149 is mounted on and supported by the top surface of the front bracket 148A, the top surface of the connection frame 150, and the top surface of the rear bracket 148B. It becomes possible. With this configuration, even if dust falls on the upper surface of the front-rear direction frame 149, the dust is easily blown away by wind or the like, and the dust does not easily stay on the upper surface of the front-rear direction frame 149. Similarly, the inclined surface 150 a and the horizontal surface 150 b of the connecting frame 150 are formed flush with each other, and dust is less likely to stay on the upper surface of the connecting frame 150.

As shown in FIGS. 9 and 12, the front support 152A is welded and fixed to the front lateral frame 145A, and the rear support 152B is welded and fixed to the rear lateral frame 145B. The

support members

151 and 151 are bolted to the front support portion 152A and the rear support portion 152B, and the storage hopper 140 is mounted on and supported by the pair of front and

rear support members

151 and 151. Thus, the storage hopper 140 is supported by the hopper support frame 143. The support member 151 is formed by bending a plate material, and is bolted to upper and lower upper and lower intermediate positions with respect to the inclined surface portions at both front and rear ends of the storage hopper 140.

The grip portion 153 </ b> A extends in the front-rear direction at a right outer position of the storage hopper 140. The connection end portion 153B is formed in a flat plate shape by crushing a round pipe material in the diameter direction, and the connection end portion 153B formed in a flat plate shape corresponds to each of the front side horizontal frame 145A and the rear side horizontal frame 145B. Is bolted to the right end of the aircraft.

As described above, since the front pipe 125a of the exhaust pipe 125 is disposed below the front side-facing frame 145A, the front pipe 125a and the collection space 142 are close to each other. From this, when the exhaust flows inside the exhaust pipe 125, radiant heat is easily radiated from the exhaust pipe 125 to the collection space 142 due to the high temperature exhaust. Therefore, as shown in FIGS. 12 and 13, a cover 154 is provided on the opposite side of the exhaust pipe 125 to the side where the threshing apparatus 104 is located, that is, between the front pipe 125a and the collection space 142. ing. The cover body 154 is formed of a flat plate bent in an L shape in the front-rear direction, and has a horizontal surface 154a above the bent portion and a vertical surface 154b below the bent portion. As shown in FIG. 14, the right end of the horizontal surface 154 a is bolted to the front of the front-rear facing frame 149, and the cover 154 is bent in the vertical direction at the right end of the horizontal surface 154 a. As a result, the cover body 154 is supported by the front of the front and rear direction frame 149. The vertical surface 154 b is adjacent to the front pipe 125 a of the exhaust pipe 125 side by side, and the radiation heat radiated from the exhaust pipe 125 is received by the vertical surface 154 b. For this reason, it becomes difficult for an operator who performs a bagging operation of grains in the working deck 135 and the recovery space 142 to feel hot air emitted from the exhaust pipe 125, and the workability in the working deck 135 and the recovery space 142 is improved.

[About the guard section]
As shown in FIGS. 8 to 13, the guard portion 160 is provided with a front arm portion 161, a rear arm portion 162, and a linear backrest portion 163. The proximal end of the front arm 161 is swingably supported by the right end of the front lateral frame 145A, and the front arm 161 extends from the proximal in a direction perpendicular to the longitudinal direction of the vehicle. The base end of the rear arm 162 is swingably supported by the right end of the rear sideward frame 145B, and the rear arm 162 extends from the base in a direction perpendicular to the longitudinal direction of the machine. The longitudinal direction of the backrest 163 extends in the longitudinal direction of the vehicle. The rear side arm portion 162 and the backrest portion 163 are configured as an integral L-shaped L-shaped member 164 by bending the round pipe material into a substantially L-shaped. A cylindrical cushion member 165 is attached to the backrest portion 163. The cushion member 165 is made of, for example, a flexible material such as urethane. The front arm portion 161 is formed of a square pipe.

The guard unit 160 is configured by connecting a plurality of divided bodies. In the second embodiment, the L-shaped member 164 integrally formed with the rear side arm portion 162 and the backrest portion 163 and the front side arm portion 161 are configured as a division body, and the division boundary is at the front portion of the backrest portion 163. To position. In the state where the guard portion 160 is divided, the cushion member 165 can be easily attached to the backrest portion 163 by externally fitting the cylindrical cushion member 165 to the backrest portion 163.

The concrete connection structure of a plurality of divided bodies will be described. A pin hole 163 a is formed at the front of the backrest 163, and an insertion hole 161 a is formed at the free end of the front arm 161. The insertion hole 161a is formed so that the backrest part 163 which is a round pipe material can be inserted. With the front portion of the backrest portion 163 inserted into the insertion hole 161a and the pin hole 163a positioned on the front side of the front arm portion 161, the pin is inserted through the pin hole 163a and pinned. Thus, the backrest 163 is held in position so as not to come off the insertion hole 161a. In other words, the front arm 161 and the backrest 163 are connected such that the free end of the front arm 161 and the front of the backrest 163 fit together. The connection between the front arm portion 161 and the backrest portion 163 is released by removing the pin pinned in the pin hole 163a.

As shown in FIG. 10, the guard portion 160 is configured to be able to swing up and down between the use state and the storage state. The use state of the guard portion 160 is a state in which the backrest portion 163 protrudes outward beyond the storage hopper 140 so as to be able to receive the worker's body (shown by a solid line in FIG. 10). The storage state of the guard portion 160 is a state in which the backrest portion 163 retracts inward in the lateral direction of the airframe and approaches the top plate 140C of the storage hopper 140 (indicated by a phantom line in FIG. 10 and a solid line in FIG. 13).

The locking portion 155A is welded and fixed to the right end portion of the front side horizontal frame 145A, and the locking portion 155B is welded and fixed to the right end portion of the rear side horizontal frame 145B. The locking portion 155A restricts the lower swing of the front arm portion 161, and when the locking portion 155A and the front arm portion 161 abut, the swing angle of the front arm portion 161 becomes the swing lower limit. Further, the locking portion 155B limits the lower swing of the rear arm portion 162, and when the locking portion 155B and the rear arm portion 162 abut, the swing angle of the rear arm portion 162 is the swing lower limit It becomes. Each of the locking portion 155A and the locking portion 155B is inclined so as to be positioned lower toward the lateral side of the machine body.

When the guard portion 160 is in use, the front arm portion 161 and the rear arm portion 162 are inclined so as to be located lower toward the lateral side of the machine, and the backrest portion 163 is the outer end of the working deck 135 It projects more towards the side of the fuselage. That is, when the guard portion 160 is in use, the backrest portion 163 is positioned below the swinging fulcrum Y of the front arm portion 161 and the rear arm portion 162, and the outer end of the working deck 135 Rather, it is located on the lateral side of the vehicle, that is, on the back side of the worker facing the storage hopper 140.

[Regarding holding mechanism]
When the guard portion 160 is in the stored state, each of the front arm portion 161 and the rear arm portion 162 inclines inward of the swing fulcrum Y in the longitudinal direction of the machine, and the backrest portion 163 is the front arm 161 And, it is located on the inner side of the vehicle than the respective rocking fulcrum Y of the rear arm portion 162. In this state, the backrest 163 is close to the storage hopper 140 and held in position by the holding mechanism 170 (see FIG. 15). As described above, the use state and the storage state are set at the positions on both sides of the guard portion 160 immediately above the rocking fulcrum Y. Therefore, the configuration in which the guard portion 160 is held in the use state or the storage state can be realized only by the own weight of the guard portion 160, and the possibility that the state of the guard portion 160 unexpectedly switches to the use state or the storage state is reduced. .

As shown in FIG. 15, of the pair of

fulcrum brackets

136, 136 mounted on the top of the top plate 140C of the storage hopper 140, the holding mechanism 170 is attached by bolting to the fulcrum bracket 136 on the front side of the machine body. . That is, the holding mechanism 170 for holding the backrest portion 163 in the stored state is attached to the storage hopper 140 via the fulcrum bracket 136. The holding mechanism 170 is formed, for example by press molding of a flat plate so as to be C-shaped in the front-rear direction. A support base end 171 located at the left end of the holding mechanism 170 is bolted to the fulcrum bracket 136. The upper accommodation portion 172 on the upper side of the machine and the lower accommodation portion 173 on the lower side of the machine extend out from the support base end portion 171 of the holding mechanism 170, respectively. A repulsive portion 175 extends forward from the support proximal end portion 171.

Inlets

174, 174 are formed. Each of the

inlets

174, 174 is formed such that the separation distance D1 of the

inlets

174, 174 is smaller than the cross-sectional diameter D2 of the backrest 163. That is, the

inlets

174 and 174 are set smaller than the cross-sectional shape of the backrest 163. In addition, the upper accommodation portion 172 and the lower end portion of the lower accommodation portion 173 are separated so that the distance between them is substantially the same as or larger than the cross sectional diameter D2 of the backrest 163. The part 172 and the lower accommodation part 173 are formed. As described above, the housing portion 176 capable of receiving and housing a part of the backrest 163 by the support base end portion 171, the upper housing portion 172, the lower housing portion 173, and the pair of upper and

lower entrance portions

174 and 174. The inner space surrounded by the housing portion 176 is a housing space S.

When the worker swings the guard portion 160 upward and the guard portion 160 is switched from the working state to the stored state, the backrest 163 abuts on the

inlets

174 and 174 of the holding mechanism 170. From this state, when the backrest portion 163 is pressed to the side where the threshing device 104 is positioned, the upper accommodation portion 172 and the lower accommodation portion 173 are elastically deformed, and the

inlets

174, 174 are spread outward in the upper and lower directions. Thereby, the entrance and exit of the backrest part 163 with respect to the accommodating part 176 are permitted. In other words, the backrest 163 penetrates the housing space S beyond the

entrances

174 and 174. Then, in the state where the backrest portion 163 enters the accommodation space S, the vertical position of the

inlets

174 and 174 is returned to the original position by the restoring force of the upper accommodation portion 172 and the lower accommodation portion 173. That is, since the separation distance D1 of each of the

inlets

174 and 174 is smaller than the cross-sectional diameter D2 of the backrest 163, even if the backrest 163 located inside the accommodation space S swings to the working state, The backrest portion 163 and the

inlet portions

174, 174 abut against each other, and the swing from the position to the working state is restricted. For this reason, in order for the backrest 163 to swing beyond the

entrances

174, 174, it is necessary for the operator to pull the backrest 163 toward the working state, and the operator moves the backrest 163 toward the working state. If the swing operation is not performed, the backrest portion 163 is held in position inside the accommodation space S. As described above, the holding mechanism 170 is configured to be able to position hold the front end side portion of the backrest portion 163 located on the front side in the extension direction.

The repulsive portion 175 has a protrusion 175 a that protrudes in the right direction of the machine at a location opposite to the side where the support base end 171 is located in the front-rear direction. When a part of the backrest 163 enters the inside of the accommodation space S, the protrusion 175a abuts on the backrest 163. In this state, the restoring force of the upper accommodation portion 172 and the lower accommodation portion 173 is transmitted to the projection 175a via the backrest 163, and the projection 175a is displaced to the left of the machine with elastic deformation of the rebounding portion 175. . From this, the storage location of the backrest portion 163 is pressed against the

entrance portions

174, 174 by the biasing force of the repelling portion 175. In other words, the backrest 163 located inside the accommodation space S is pressed at three points by the pair of upper and

lower inlets

174 and 174 and the protrusion 175a. Thus, when the guard portion 160 is in the stored state, the storage location of the backrest portion 163 is maintained in the state stored in the interior of the storage portion 176 without rattling inside the storage space S.

[Arrangement of Lighting Device]
As shown in FIGS. 10 and 12, a lighting device 137 that illuminates the collection space 142 is supported at the rear of the front-to-rear frame 149. A bracket 138 configured by an angle member having an L-shaped cross section is bolted to the rear of the front-to-rear frame 149, and the bracket 138 holds the vertical position from the connection point with the front-to-front frame 149 toward the rear right of the machine Extend out. A lighting device 137 is bolted to the extended end of the bracket 138, and the lighting device 137 is a connection point between the rear vertical frame 144C and the rear sideward frame 145B in the space between the threshing device 104 and the storage hopper 140. It is located adjacent to. The irradiation direction of the illumination device 137 is directed to a direction that can irradiate the space below the storage hopper 140, that is, the entire collection space 142. A light emitting diode is used as a light source of the lighting device 137, but a high-intensity discharge (HID) lamp, a xenon lamp, or the like may be used.

With this configuration, the lighting device 137 is disposed near the corner inside the airframe at the rear of the storage hopper 140, so the lighting device 137 can be used as a recovery space even if the illumination range of the lighting device 137 is narrow. It can illuminate a wide range of 142. In addition, since the lighting device 137 is located between the threshing device 104 and the storage hopper 140, the lighting device 137 can illuminate the collection space 142 without being disturbed by the storage hopper 140.

[Guide structure of grain in storage hopper]
As shown in FIG. 17 and FIG. 18, the upper end of the grain milling apparatus 120 is in fluid communication with the storage hopper 140. The grain feeding device 120 is provided with a vertical feed screw 180, a flat plate-like rotating blade 181, and a discharge case 182 covering the periphery of the rotating blade 181. The longitudinal feed screw 180 vertically transports the grain from the bottom of the threshing device 104. The rotary blade 181 is connected to the end of the vertical feed screw 180 in the transport direction, and the rotary blade 181 rotates around the axis P integrally with the vertical feed screw 180. A discharge port 182 a is formed in the discharge case 182 at a position facing the storage hopper 140. The vertical height of the discharge port 182 a is set larger than the vertical height of the rotary vane 181 in the axial direction of the rotary vane 181. Of the discharge case 182, the inner wall 182b on the front side of the axis P substantially extends in the lateral direction of the machine in plan view, and the inner wall 182c of the discharge case 182 on the rear side of the axis P in the lateral direction Tilt backwards. The rotary vanes 181 rotate clockwise in plan view, and the grains fed to the discharge case 182 are pushed out of the discharge port 182 a into the interior of the storage hopper 140 by the rotary vanes 181.

The grain raising apparatus 120 in the second embodiment is provided on the front side of the storage hopper 140. Therefore, if the grain is simply pushed out from the discharge port 182a to the inside of the storage hopper 140, the

funnel portions

146, 146 at the front two places among the three lower

narrow funnel portions

146, 146, 146 There is a possibility that the grains are stored unevenly, and it is difficult for the grains to be stored in the funnel portion 146 at the rear of the storage hopper 140. In order to avoid such a disadvantage, the anchor guide plate 183 is connected in a cantilever manner to the front end of the discharge port 182a.

The anchor guide plate 183 is formed in a flat plate shape, and in a state where the tip of the rotary blade 181 comes closest to the anchor guide plate 183, the anchor guide plate 183 is right rear, ie, flat along the tangential direction of the rotary blade 181. It inclines toward the left and right center of the rear in storage hopper 140 visually. The vertical width of the anchor guide plate 183 extends to the lower half of the vertical width of the discharge port 182a. Thus, among the grains discharged from the discharge port 182a, the grains in the lower half are pressed against the throwing guide plate 183 and splashed to the rear of the storage hopper 140. Further, among the grains discharged from the discharge port 182 a, the grains in the upper half are pushed out toward the front of the storage hopper 140 along the front inner wall 182 b of the discharge case 182.

Thus, the grain discharged from the discharge port 182 a is pushed against the anchor guide plate 183 and splashed to the rear of the storage hopper 140, so that the grain is transferred to the funnel 146 at the rear of the storage hopper 140. Is easy to be stored. As a result, the grains are stored in a well-balanced manner with respect to the three

funnel portions

146, 146, 146 in the storage hopper 140, and the storage efficiency of the storage hopper 140 is improved.

Although the vertical width of the throwing guide plate 183 covers the lower half of the vertical width of the discharge port 182a, the vertical width of the throwing guide plate 183 can be changed as appropriate. In addition, a guide plate that is inclined in a direction different from that of the anchor guide plate 183 may be separately provided above the anchor guide plate 183 in the discharge port 182a. In this case, the extension length from the discharge port 182a of the guide plate may be the same as the anchor guide plate 183 or may be different from the anchor guide plate 183.

In addition to the configurations shown in FIGS. 17 and 18, a configuration is also possible in which the flow-down guide plate 184 as shown in FIGS. 19 and 20 is provided in the rectangular box 140A of the storage hopper 140. In addition, although the throwing guide plate 183 is shown in FIG. 19 and FIG. 20, the structure in which the throwing guide plate 183 is not provided may be sufficient. The flow guide plate 184 is formed as a flat plate of an equilateral hexagon having five corner portions C1, C2, C3, C4, C5, and C6. The front end portion of the flow guide plate 184 is located at the side E1 extending in the lateral direction of the machine across the corner portion C1 and the corner portion C2, and is located substantially at the same location as the front end portion of the discharge port 182a in a side view. The rear end portion of the flow guide plate 184 is a portion of a side E4 extending in the lateral direction of the machine across the corner C4 and the corner C5, and is positioned rearward of the funnel 146 in the front and rear center in a side view. . The upper and lower positions of the flow guide plate 184 are inclined such that the lower the position, the closer to the side E4. For this reason, the grain discharged from the discharge port 182a is guided by the funnel 146 to the side where the funnel 146 is located at the end.

A side E6 is formed across the corner portion C1 and the corner portion C6 in the flow guide plate 184, and the side E6 is connected and fixed to the left side wall portion of the rectangular box-like portion 140A. Further, in the flow-down guide plate 184, the location where the corner portion C3 is located is connected and fixed to the airframe right side wall portion of the storage hopper 140. The side E1 is located immediately above the foremost funnel portion 146 and is formed along the lateral direction of the vehicle. The corner portion C2 is positioned right above the funnel portion 146 at the front end, and the side E2 is inclined so as to be closer to the airframe right side wall portion of the rectangular box-like portion 140A as the position located on the rear side.

The corner C <b> 4 and the corner C <b> 5 are located closer to the center in the left-right direction in the storage hopper 140. The side E3 extending between the corner C3 and the corner C4 is inclined so as to be closer to the center of the storage hopper 140 as it approaches the corner C4 in a plan view. Further, the side E5 extending between the corner C5 and the corner C6 is inclined so as to be positioned closer to the left and right center of the storage hopper 140 as it approaches the corner C5 in a plan view. From this, the lateral width of the flow-down guide plate 184 on the rear side of the corner portion C3 is formed narrower as it approaches the side E4.

Among the grains discharged from the discharge port 182a and placed on the flow guide plate 184, most of the grains falling from the side E1 are stored in the funnel portion 146 at the front end, and the grains falling from the side E2 are front two It is stored in any of the two funnels 146. The grains remaining on the downflow guide plate 184 without falling from the side E1 or the side E2 can be dropped from the side E3 and the side E4 while being guided by the funnel portion 146 at the end. Most of the grains falling from the side E3 and the side E5 are stored in the funnel portion 146 in the front and rear center, but most of the grains falling from the side E4 are stored in the funnel portion 146 at the rearmost end. Thus, since most of the grains discharged from the discharge port 182a are guided by the downflow guide plate 184 to the funnel portion 146 at the end, the grains are balanced against the three

funnel portions

146, 146, 146. It is well stored and the storage efficiency of the storage hopper 140 improves.

The flow-down guide plate 184 shown in FIG. 20 is configured to be inclined only in the front-rear direction and not inclined in the left-right direction, but may be configured to be inclined not only in the front-rear direction but also in the left-right direction. That is, the downstream guide plate 184 may be configured to be inclined so as to be positioned lower toward the left or right. Although the flow guide plate 184 is formed in a flat plate shape, the vertical position of the left and right center of the flow guide plate 184 may be curved lower than the vertical position of the outer side. With this curved configuration, most of the grains placed on the flow-down guide plate 184 are guided by the side E4 and easily fall from the vicinity of the corner C4.
