It is sent to the first beater 241 side, that is, obliquely upward to the rear side, along the rear end lower plate portion 24a and the connecting plate portion 232a.
- the first curved plate portion 232b of the bottom plate 232 is connected to the rear of the connection plate portion 232a and is located below the first beater 241. Therefore, the harvested cereal meal sent from the connection plate portion 232a to the first beater 241 side passes between the first beater 241 and the first curved plate portion 232b, and is sent rearward along the first curved plate portion 232b. It is done.
- the first curved plate portion 232b is provided with a first inclined portion 236 that is inclined upward in the backward direction at least at the rear portion thereof. Therefore, the harvested cereal meal sent rearward along the first curved plate portion 232 b is sent rearward and obliquely upward toward the second beater 242.
- the second curved plate portion 232c of the bottom plate 232 is connected to the rear of the first curved plate portion 232b and is located below the second biter 242. Therefore, the harvested cereal meal sent from the first beater 241 to the second beater 242 side passes between the second beater 242 and the second curved plate portion 232c, and moves backward along the second curved plate portion 23 2c. Sent.
- the second curved plate portion 232c is provided with a second inclined portion 237 inclined obliquely upward and rearward at least at the rear portion thereof. Therefore, the harvested cereal meal sent rearward along the second curved plate portion 232c is sent obliquely upward rearward toward the handling chamber 41 of the threshing portion 7.
- the degree of freedom is increased with respect to the setting of the cutting grain feeding position to the threshing section 7 relative to the cutting grain feeding position of the transport section 5.
- the degree of freedom regarding the arrangement of the threshing unit 7 and the sorting unit 8 is increased.
- second beater 242 when second beater 242 is arranged obliquely upward and rearward of first beater 24 beam, it is possible to set the cutting grain feed position to threshing portion 7 to a high position.
- the transport unit 5 in the center cabin type combine, the transport unit 5 is arranged under the cabin 6, and the transport unit 5 is at a low position, or the harvested cereals of the transport unit 5 are sent out. The position may be lower.
- the cutting portion of the transport unit 5 is lowered, it is necessary to lower the height position of the threshing unit and the sorting unit below it, and the size and capacity of the threshing unit and the sorting unit that can be mounted are limited.
- the present embodiment even if the height below the cabin 6 is reduced and the cutting portion of the transport unit 5 is lowered, the height of the cutting portion feeding position to the threshing unit 7 is reduced. Is prevented. This prevents the size and capacity of the threshing section and sorting section that can be mounted from being restricted, and the threshing section and sorting section of the required size and capacity can be mounted.
- the first beater 241 and the second beater 242 are shaft bodies extending in the combine vehicle width direction.
- the force that is pivotally supported by the at least one of the beaters may be pivotally supported while being movable in the direction perpendicular to the rotation axis.
- the height of the beater and the distance between the axes of the beater can be adjusted, and adjustment can be made so that the harvested grain can be efficiently conveyed.
- the position of the beater can be adjusted to a more suitable position according to the type and state of the harvested cereal.
- the size of the space between the first beater 241 and the second beater 242 can be adjusted. Since both beaters 241,242 rotate in the same direction (counterclockwise in FIG. 17), the harvested cereal grains located between both beaters 241,242 receive the upward force from the first beater 241 while the second beater 242 force , And others receive downward force. Therefore, if the distance between the two beaters 241, 242 is too short, the space between the two beaters 241, 242 becomes narrow, and there is a risk that the harvested cereal kernels will be damaged by receiving the force from both the beaters 241, 242.
- the combine 1A of the present embodiment is similar to the first embodiment in that the harvesting part 4 disposed in front of the traveling part 2 and the harvested grain harvested by the harvesting part 4 are used.
- a transport unit 5 for transporting the straw a cabinet 6 disposed above the transport unit 5 so as to be positioned at a substantially central portion in the vehicle width direction, and a threshing unit 7 for threshing the harvested cereal rice cake disposed behind the cabin
- a Spotify tank 65 in which the threshed grains are stored.
- the left end of the darling tank 65 in the vehicle traveling direction is located above the left end of the threshing section 7, and the right end of the darlen tank 65 is It is located below the right end of the discharge auger 67 located in the storage position. That is, the size of the darren tank 65 in the vehicle width direction extends over the entire width of the combine, and at least a part of the darren tank 65 is disposed above the threshing portion 7.
- a cerealing device 57 is arranged on the left side of the combine 1A.
- the Spotify tank 65 includes a left inclined bottom plate 65b inclined inward and downward from the lower end of the left wall 65a, and a right inclined bottom plate 65d inclined inward and downward from the lower end of the right wall 65c.
- the lower ends of both inclined bottom plates 65b, 65d reach the lateral carry-out auger 250 extending in the front-rear direction.
- the lateral carry-out ogar 250 for discharging the grains in the dalen tank 65 is installed at the lower end of the dalen tank 65.
- the lower end portion of the darren tank 65 is rotatably connected to the lateral carry-out auger 250. Accordingly, the darren tank 65 is rotatable about the rotation axis of the lateral unloading auger 250 with the lateral unloading auger 250 as the rotation axis.
- the horizontal carry-out auger 250 conveys the grains in the dull tank 65 to the lower end of the vertical transfer auger 66 located at the rear end of the horizontal carry-out auger 250. Therefore, the grain conveyed to the lower end of the vertical conveyance auger 66 by the horizontal conveyance auger 250 is sent to the discharge auger 67 through the vertical conveyance auger 66 and discharged from the discharge auger 67 to a transport vehicle or the like. Is done.
- the horizontal carrying out auger 250 is arranged on the side of the handling cylinder 42 of the threshing unit 7. That is, the lower end of the Spotify tank 65 is disposed on the side of the threshing section 7. More specifically, the lower end of the Spotify tank 65 is disposed above the lower end of the handling cylinder 42. Therefore, the DAREN TANK 65 has a larger dimension in the width direction and a dimension in the front-rear direction than the dimension in the depth direction. In a conventional combine where the darren tank is located on the right side of the threshing section, the weight on the right side of the combine increases in proportion to the amount of grain stored in the darren tank, so the balance of the combine, especially the It was not easy to maintain a good balance.
- the grains are stored over the entire width of the combine 1A.
- grain is also stored on the threshing section 7 side (the vehicle left side).
- This structure minimizes the effect of the amount of stored grain on the left and right balance of the combine. Therefore, it is easy to maintain the combine balance, particularly the left-right balance. In other words, the left / right balance of the combine is improved.
- the grains stored above the threshing unit 7 may be reduced. There is a possibility that it will not fall to the side auger 250 installed at the lower end of the Spotify tank 65, and may remain in the Spotify tank 65.
- the Daren tank 65 is made to be rotatable around the rotation axis of the horizontal carrying out auger 250, the grain remaining in the position where it is difficult to fall can be rotated by rotating the Duren tank 65. It can be reliably dropped at 250.
- the threshing unit 7 includes a handling chamber 41 that accommodates a handling cylinder 42 that threshs the harvested cereal meal, and the handling chamber 41 includes a handling chamber cover 41a that can be freely opened and closed. . Therefore, a connecting member for transmitting the turning operation of the grain tank 65 to the handling chamber cover 41a may be provided so that the handling chamber cover 41a can be opened and closed in conjunction with the turning of the dull tank 65. In this way, the handling chamber cover 41a can be opened at the same time as turning the darlen tank 65, so that it is easy to open and close the handling chamber cover 41a without having to open the handling chamber cover 41a directly.
