  In the above-described combine, when the grain storage unit is provided with a necessary capacity while suppressing the increase in the lateral width of the combine storage unit as the size of the grain storage unit increases in the left-right direction, The size in the vertical direction of the fuselage may increase. Then, the height of the grain storage part on the traveling machine becomes higher than the height of the threshing device, and when the grain is stored in the grain storage part, the center of gravity of the machine is high due to the weight of the grain in the storage part. There was a problem.

  An object of the present invention is to provide a combine that can be obtained in a stable state with a small lateral width while providing a necessary capacity in a grain storage unit.

According to the first aspect of the present invention, there is provided a traveling machine body including a pair of left and right crawler traveling devices, a driving unit provided on one end side in the left-right direction of the front body of the traveling machine body, and a swinging unit on the other end side in the left-right direction of the traveling machine body. Mowing pretreatment device connected to move up and down freely, a plurality of pulling devices arranged in the left-right direction of the machine body in the pre-harvest processing device, a threshing device and a grain storage arranged in the horizontal direction of the machine body in the traveling machine body In a combine equipped with
Of the pair of left and right crawler traveling devices, the distance between the left and right center of the ground wheel in the crawler traveling device on the side close to the grain storage portion and the machine body left and right outer end of the grain storage portion is The distance between the left and right center of the grounding wheel in the crawler traveling device closer to the threshing device in the crawler traveling device and the outer side end in the left and right direction of the machine body of the threshing device is set smaller.

  According to the configuration of the first aspect of the present invention, the size of the grain storage part in the left-right direction of the machine body is reduced to make the width as a combine as small as possible, and the capacity of the grain storage part is set to the required capacity. As a result, even if the size of the grain storage unit in the vertical direction of the fuselage increases and the center of gravity of the fuselage increases due to the weight of the stored grain in the grain storage unit, the crawler traveling on the side close to the grain storage unit The distance between the left and right center of the grounding wheel in the device and the lateral left and right outer ends of the grain storage unit is the right and left center of the grounding wheel in the crawler traveling device near the threshing device and the lateral left and right outer end of the threshing device. By being smaller than the interval, the center of gravity of the body is positioned as much as possible in the left-right direction of the body with respect to the crawler, and the falling angle on the grain storage unit side can be maximized.

  According to the configuration of the first aspect of the present invention, the crawler on the side close to the threshing device is the distance between the left and right center of the ground ring in the crawler traveling device on the side close to the grain storage unit and the machine body laterally outer end of the grain storage unit. Because it is smaller than the distance between the left and right center of the grounding wheel in the traveling device and the laterally outer end of the threshing device, the grain storage part and the planting can be established even if the cut yard is located on the side of the traveling aircraft. The amount of protrusion of the grain storage portion from the traveling machine body to the lateral outer side can be suppressed so that contact with the cereal can be easily prevented or avoided.

Accordingly, a necessary amount of grain can be stored in the grain storage unit, and a compact combine with a small width is easy to operate, and a combine with a high tipping angle and high stability can be obtained. .
In addition, it is easy to prevent or avoid contact between the planted cereal grains located on the side of the traveling machine body and the grain storage part, and it is easy to enable middle cutting and surrounding cutting.

  In the second aspect of the present invention, a pair of the pull-up devices is provided, and the position of the left and right outer ends of the crawler belt in the left crawler traveling device and the position of the left outer divider tip of the pre-cutting processing device are The position of the outer side end of the crawler belt in the left and right direction of the crawler belt in the crawler traveling device on the right side and the position of the front end of the divider on the right side of the pre-cutting processing device are matched or substantially matched in the left and right direction. It is matched.

  According to the configuration of the second aspect of the present invention, the distance between the left outer divider tip and the right outer divider tip of the pre-cutting processing apparatus is the distance between the left crawler lateral outer edge and the right crawler lateral outer edge (hereinafter referred to as traveling). In this state, the pre-cutting processing device can perform the cutting operation immediately before the stepping cost of the traveling machine.

  Therefore, it is possible to perform an excellent middle cutting and surrounding cutting operation in which the stepping of the planted cereal by the left and right crawler traveling devices does not occur.

  According to the third aspect of the present invention, the pulling chain horizontal turning path at the lower end of the pulling device located closest to the operating part among the plurality of pulling devices is set to the pulling chain horizontal turning path at the lower end of the other pulling device. It is set longer than the turning route.

  According to the configuration of the third aspect of the present invention, an inexpensive combine with a simple structure of the pre-cutting processing device can be obtained while performing good middle cutting and surrounding cutting without stepping on the planted cereal. be able to.

  In other words, in the case of middle cutting or peripheral cutting, the planting cereals located on the driving unit side are not raised by the crawler traveling device, and the lower side of the pulling device on the most operating unit side is raised. Along the turning route, the vehicle body is pulled inward in the left-right direction, joined with the planted cereals from the front of the pull-up device on the most operating part side, and is raised and processed by the pulling device on the most driving part side. In other words, in the case of middle cutting and surrounding cutting work, the planted cereals with more planting strips than in the case of turning harvesting in the pulling device on the most operating part side so as not to step on the planted cereal by the crawler traveling device. Introduce firewood. Thereby, the number required for the raising device provided in the pre-cutting processing device can be reduced by a number smaller than the number of cutting lines in the middle cutting and the surrounding cutting work.

  In this 4th invention, the recessed part which forms the clearance gap between the apparatus part of the said pre-harvest processing apparatus and the said control tower is provided in the end part of the pre-cutting processing apparatus of the control tower standingly arranged in the said operation part.

  According to the configuration of the fourth aspect of the present invention, it is possible to carry out a good middle cutting and surrounding mowing work that is not stepped on by the crawler traveling device of the planted cereal, while the overall length of the combine is short and the compact combine is reduced. Can be obtained.

  In other words, the raising chain horizontal turning path at the lower end of the pulling device on the most operating part side is set so that the planted culm located on the driving part side is introduced into the pulling device on the most operating part side. If it is longer than the raising chain horizontal turning path at the lower end of the raising device, the lateral width of the part of the pre-cutting device equipped with the divider and the raising device is increased. However, even when the cutting pretreatment device is connected to the traveling body as much as possible, when the cutting pretreatment device is moved up and down, the device portion of the cutting pretreatment device passes through the recess of the control tower and controls the cutting pretreatment device. The front and rear length of the entire combine can be shortened as much as possible without interfering with the tower.

  In this 5th invention, the auxiliary conveyance apparatus which conveys a planted cereal grain toward the body back is provided behind the plurality of raising apparatuses, and the auxiliary conveying apparatus of the raising apparatus located closest to the operating unit side is provided. The other raising device is arranged at a higher arrangement height than the auxiliary conveying device.

  According to the configuration of the fifth aspect of the invention, troubles such as clogging due to the broken culm of the culm can be performed while performing good middle cutting and surrounding mowing without stepping by the crawler traveling device of the planted culm. An easy to avoid combine can be obtained.

  In other words, the raising chain horizontal turning path at the lower end of the pulling device on the most operating part side is set so that the planted culm located on the driving part side is introduced into the pulling device on the most operating part side. If the raising chain is made longer than the raising chain lateral turning path at the lower end of the raising device, the planted culm positioned on the driving unit side is introduced into the raising unit on the most operating unit side while being bent relatively large. Then, it is raised in the bent state and is received by the auxiliary transfer device behind the device. When the auxiliary transport device is used to carry the cereal straw, the auxiliary transport device is located at a higher height than the other auxiliary transport devices, so that the cereals can carry the transport action of the auxiliary transport device from the ground as much as possible. It will be received at a high point, and it will be difficult for the corn straw to bend at a steep angle. As a result, it is difficult for the culm to be broken, and the subsequent conveyance is less likely to be disturbed or clogged.

  In the sixth aspect of the present invention, the pulling device located closest to the operating section includes a chain guide member for lateral rotation that raises the chain and raises it from the chain return path and guides it to the chain horizontal path. A raising chain guide member that is raised from the raising chain lateral path and guided to the chain raising path, and the chain winding curvature of the raising chain guide member is set to the chain winding curvature of the lateral chain guide member. It is set larger than.

  According to the configuration of the sixth invention, troubles such as clogging due to the broken culm of the culm can be performed while the good middle cutting and surrounding mowing work without stepping by the crawler traveling device of the planted culm can be performed. An easy to avoid combine can be obtained.

  In other words, the raising chain horizontal turning path at the lower end of the pulling device on the most operating part side is set so that the planted culm located on the driving part side is introduced into the pulling device on the most operating part side. When the elongating chain is turned longer than the traverse chain traverse path at the lower end of the elevating device, the planted culm positioned on the operating unit side is bent relatively large while the lower end of the erecting device on the most operating unit side. The chain is pulled inward in the lateral direction of the traveling machine body along the horizontal chain path of the chain, and is further bent and introduced into the chain path along the chain ascending path. In this way, when the cereal is raised and raised from the lower end of the device and introduced into the path, the chain winding curvature of the raising chain guide member is larger than the chain winding curvature of the side turning chain guide member, The cereal is raised from the lower end of the apparatus and introduced into the path along a curved corner having a relatively large curvature, so that the cereal is less likely to be bent at a steep angle. As a result, it is difficult for the culm to be broken, and the subsequent conveyance is less likely to be disturbed or clogged.

  In the seventh aspect of the invention, the upper end of the raising chain raising path of the raising device located closest to the operating portion is arranged at a higher arrangement height than the upper end of the raising chain raising path of the other raising device. It is.

  According to the configuration of the seventh aspect of the invention, it is possible to obtain a combine that has good performance of raising the culm while being able to perform good middle cutting and surrounding mowing work without stepping by the crawler traveling device of the planted culm. it can.

  In other words, when the pulling device located closest to the driving unit and the pulling device adjacent to the pulling device are arranged so that their pulling paths face each other, the pulling claws of the two pulling devices are brought into contact with each other. By actuating it, the cereal can be raised without causing it to escape from the nail. In this way, in order to raise the opposing pulling devices and drive them synchronously in the butted state of the claws, the circumferential lengths of the pulling chains provided in both the pulling devices are raised and set to a length that is an integral multiple of the pawl pitch.

  In order for the planted cereals located on the driving unit side to be introduced into the pulling device on the driving unit side, the pulling chain sideways path at the lower end of the pulling device on the driving unit side is raised to the other driving unit. If it is longer than the raising chain lateral path of the lower end of the device, the upper end of the raising chain raising path of the raising device on the most operating part side and the adjacent raising device is located at the same arrangement height. In this case, even if the raising chain provided in both the raising devices is raised and has a circumferential length that is an integral multiple of the claw pitch, the raising claws of the both raising devices may not be in a butt state. . This is because the pulling chain traverse path of the pulling device on the most operating part side is longer than the pulling chain traverse path of the adjacent pulling apparatus, and the pulling chain traverse path of the pulling apparatus on the furthest driving part side is longer. This is because the length of the pulling chain applied to the path is different from the length of the pulling chain applied to the pulling chain transverse path of the adjacent pulling device.

  According to the configuration of the seventh aspect of the present invention, the chain length applied to the raising chain horizontal turning path of the pulling device on the most operating part side and the chain length applied to the raising chain horizontal turning path of the adjacent raising device are obtained. Even if there is a difference, the upper end of the pulling chain raising path of the pulling device on the most operating part side is located at a higher arrangement height than the upper end of the pulling chain rising path of the other pulling apparatus, The pulling chain length of the pulling chain of the side pulling device and the pulling chain length of the pulling chain of the adjacent pulling device are different from each other. Due to the offset between the difference in the length of the raised chain and the difference in the length of the raised chain applied to the horizontal path of the raised chain, the pulling device on the most operating part side and the pulling device adjacent to this are separated. It is possible to tune driven by a butt state of causing the nails.

  In addition, since the upper end of the pulling chain raising path of the pulling device on the most operating part side is located at a higher arrangement height than the upper end of the pulling chain rising path of the other pulling apparatus, the most driving part side The pulling claws of both pulling devices can be brought into contact with each other while the length of the chain rising path is not shorted by the pulling device.

  Therefore, the pulling chain side turning path at the lower end of the pulling device on the most operating part side is longer than the pulling chain side turning path at the bottom end of the other pulling apparatus, while the pulling chain on the most operating part side is raised. Even when the device and the pulling device adjacent to this are arranged so that the pulling paths are opposite to each other, both the pulling devices are pulled up and driven synchronously with the claws in contact with each other, and the pulling-up on the most operating part side is performed. The apparatus can be provided with an elevating chain raising path that does not have a short length, so that the cereal can be raised and not escaped from the claws, and can be raised to the tip side as much as possible to give rise to the processing.
