JP 2012-210163 A

  In the above-described conventional configuration, the fuel tank is a configuration that is deployed using an empty area for harvesting devices such as a threshing device and a grain storage unit at the rear of the traveling aircraft, and the outer shape of the fuel tank It was constrained to have a shape that can be stored in an installation space corresponding to an empty area in the airframe, and the amount of fuel stored was small. If the fuel tank is to be changed to a larger one, the fuel tank becomes larger than the installation space and protrudes outward from the traveling aircraft body, so it is difficult to increase the capacity of the fuel tank. It was.

  In addition, the cover that covers the lateral outside of the transmission mechanism provided at the lateral outside portion of the threshing device is enlarged, not only the cover is enlarged, but also the support structure must be strong, and the structure of the exterior part is There was also the disadvantage of becoming complicated.

  The object of the present invention is to improve the arrangement of the fuel tank so that the fuel tank can be made large and the amount of fuel stored can be increased, and the structure of the exterior portion can be simplified. The point is to provide a harvesting machine.

The characteristic configuration of the harvester according to the present invention is such that the threshing device for threshing the crop harvested in the harvesting section at the front of the aircraft and the fuel tank are arranged in the horizontal direction of the aircraft, and the engine therebetween. Provided with a transmission mechanism that transmits the power of the threshing device,
The fuel tank is located on one end side in the lateral width direction of the traveling aircraft body, and is provided with a side surface on the outer side in the lateral width direction being exposed laterally outward of the aircraft body.

  According to the present invention, the threshing device and the fuel tank are provided in a state of being aligned in the lateral width direction of the body. Further, a transmission mechanism for transmitting engine power to the threshing device is provided between the threshing device and the fuel tank.

  In this way, the fuel tank is provided in a state of being located on the lateral side of the threshing device which is a large device, so that the fuel tank is installed on the traveling aircraft body by forming it long in the longitudinal direction of the aircraft, for example It is possible to increase the fuel storage amount by making the fuel tank large without adversely affecting the arrangement of the apparatus, or increasing the front and rear length of the traveling machine body.

  The fuel tank is located at one end side in the width direction of the traveling machine body, and the side surface on the outer side in the width direction is exposed to the outer side of the machine body. In other words, the fuel tank is positioned on the outer side in the lateral width direction of the threshing device or the transmission mechanism and has a function as an exterior cover.

  As a result, it is possible to use the fuel tank effectively and to reduce the size of the dedicated cover for covering the lateral outer side of the transmission mechanism, or to omit the cover, which simplifies the structure of the exterior part. It becomes possible.

  Therefore, according to the present invention, by improving the arrangement of the fuel tank, it is possible to increase the amount of fuel stored by making the fuel tank large and to simplify the structure of the exterior portion. We were able to provide a possible harvester.

  In the present invention, it is preferable that the fuel tank has a longer front-rear width than a vertical width and is formed in a long shape in the front-rear direction in a side view of the body.

  According to this configuration, since the fuel tank is formed in an elongated shape in the front-rear direction, the fuel tank can be made large and the amount of fuel stored can be increased. Further, since the front-rear width is longer than the vertical width in a side view of the body, the vertical width is shorter than the front-rear width.

  As a result, since the position of the upper surface where the fuel supply port is formed can be set lower, it becomes easier to refuel.

  In the present invention, it is preferable that the fuel tank is longer in the vertical direction than the lateral width in the front view of the body, and is formed in an elongated shape in the vertical direction.

  According to this configuration, the fuel tank is formed in an elongated shape in the vertical direction when viewed from the front of the machine body, and the lateral width is narrower than the vertical width. As a result, although the fuel tank is large and has a large amount of fuel storage, the fuel tank becomes narrow along the lateral width direction of the traveling aircraft, so that the lateral dimension of the traveling aircraft is reasonably deployed without increasing the size. It becomes possible.

  In the present invention, it is preferable that the fuel tank is longer in the front-rear direction than the left-right width and is formed in a long shape in the front-rear direction in the top view of the body.

  According to this configuration, since the fuel tank is formed in an elongated shape in the front-rear direction, the fuel tank can be made large and the amount of fuel stored can be increased. In addition, when viewed from the top of the body, it is formed in a long shape in the front-rear direction, and the left-right width is narrower than the front-rear width. As a result, although the fuel tank is large and has a large amount of fuel storage, the fuel tank becomes narrow along the lateral width direction of the traveling aircraft, so that the lateral dimension of the traveling aircraft is reasonably deployed without increasing the size. It becomes possible.

  In the present invention, it is preferable that the fuel tank covers a portion on one end side in the width direction of the traveling machine body.

  According to this configuration, since the fuel tank is located at one end in the lateral width direction, an operator located laterally outward from the fuselage can approach the fuel tank, and fuel replenishment work and fuel storage amount for the fuel tank can be achieved. It becomes easy to perform confirmation work.

In the present invention, the fuel tank covers a part of the lateral width direction one end side portion of the traveling aircraft body,
It is preferable that a cover body that covers the other part of the one end side portion in the width direction of the traveling machine body is provided.

  According to this configuration, since the other part of the lateral width direction one end side portion of the traveling machine body is covered with the cover body different from the fuel tank, for example, when performing maintenance work of the threshing device, than the fuel tank By adopting a configuration in which the lightweight cover body is opened and closed, it becomes possible to perform work more easily than opening and closing the fuel tank.

  In the present invention, it is preferable that the fuel tank is placed and supported on an airframe frame and covers a lower portion of one end side portion of the traveling airframe in the lateral width direction.

  According to this configuration, the fuel tank is placed and supported on the body frame at a low position so as to cover the lower portion of the lateral width direction one end side portion of the traveling body. In this way, the fuel tank is stably supported by the fuselage frame at a low position. For example, even if the fuel tank is full and the fuel tank is heavy, it is unstable as the aircraft travels. It becomes easy to avoid entering a state.

  In the present invention, it is preferable that the fuel tank covers a lower portion corresponding to a position below the handling chamber of the threshing device among the positions in the width direction one end side of the traveling machine body.

  According to this structure, the sorting processing part which sorts the threshing processed material after processing the harvested cereal rice cake in the handling room into the grain and other dust in the lower part of the handling room of the threshing device However, the fuel tank covers the lower part corresponding to the lower part of the handling room of the threshing device corresponding to the sorting processing unit.

  Since the handling chamber is provided with a handling cylinder and a receiving net to handle and process the harvested cereal meal, there is a possibility that straw scraps and the like adhere and accumulate and members such as the handling cylinder and the receiving net wear. As a result, the handling room has a high frequency of maintenance work. On the other hand, the sorting processing unit is less likely to deposit and accumulate cracks and the like and wear the members than the handling chamber, and the frequency of maintenance work is less than that of the handling chamber.

  When fuel is stored, the fuel tank may become heavy, but because the lower part corresponding to the lower part of the handling chamber where the frequency of maintenance work is small is covered with the fuel tank, During maintenance work, in order to open the lower part corresponding to the lower part of the handling chamber, the frequency of opening the heavy fuel tank is low, and the upper part corresponding to the handling room is not opened. Compared to the case of covering, it becomes easier to reduce the work load.

In the present invention, the fuel tank covers a part of the lateral width direction one end side portion of the traveling aircraft body,
A cover body covering the other part of the lateral direction one end side location of the traveling machine body is provided,
It is preferable that the cover body covers an upper portion of one end side portion in the width direction of the traveling machine body.

  According to this configuration, the fuel tank covers a lower portion corresponding to a lower portion than the handling chamber at one end in the width direction of the traveling machine body, and the cover body is disposed at one end side position in the width direction of the traveling machine body. The upper part corresponding to the handling room is covered.

  The handling room has a high frequency of maintenance work, but the cover body covering the upper part corresponding to the handling room is lighter than the fuel tank, so that the upper part corresponding to the handling room is opened. Even if the cover body is opened frequently, the work load is easily reduced as compared with the case where the fuel tank is opened.

  In the present invention, it is preferable that the cover body is supported so as to be swingable over an action posture that covers the upper portion of one end of the traveling body in the lateral width direction and an open posture that opens the upper portion.

  According to this configuration, when performing maintenance work, the posture can be switched between the action posture and the open posture by swinging the cover body. If the posture is switched by the swing operation, a part of the load of the cover body can be supported at the swing fulcrum, so that the cover body can be compared with the configuration in which the cover body is switched to the open posture by removing the entire cover body. Therefore, it is possible to switch the posture in a state where there is no burden of burdening the entire weight of the robot and the work load is small.

  In the present invention, the fuel tank is swingably supported between a normal use posture that covers one end in the width direction of the traveling machine body and an open posture that opens the one end in the width direction and projects outward. It is preferable.

  According to this configuration, when the fuel tank is in the normal use posture, the fuel tank is in a state of covering one end side in the width direction of the traveling aircraft body, and when switched to the open posture, the one end side in the width direction of the traveling aircraft body is opened to the outside. It will be overhanging.

  The fuel tank is swingably supported between the normal use posture and the open posture. In such a configuration in which the posture is switched by the swing operation, a part of the load of the cover body can be supported at the swing fulcrum, so that the fuel can be compared with the configuration in which the entire fuel tank is removed to switch to the open posture. It is possible to switch postures without burdening the entire weight of the tank and with less work load.

  In the present invention, it is preferable that the fuel tank is supported so as to be swingable around a vertically swinging shaft core.

  According to this configuration, when swinging around the swing axis centering in the vertical direction, a large part of the weight of the fuel tank can be supported at the swing fulcrum location, and at the free end side location. The weight of the fuel tank can be swung while being received and supported by the body frame, thereby reducing the work load when the posture of the fuel tank is switched.

  In the present invention, it is preferable that the vertically swinging axis is located on the rear side of the body of the fuel tank.

  According to this configuration, since the fuel tank swings around the vertical axis located on the rear side of the machine body, the swing fulcrum portion is not easily damaged by the vibration of the machine body. That is, in the harvesting machine, there is a device that performs harvesting work on the front side of the aircraft, so the vibration on the front side of the aircraft is large due to harvesting work, but the vibration on the rear side of the aircraft is less than that on the front side. is there.

In the present invention, the fuel tank is configured to cover a lower portion on one end side in the width direction of the traveling aircraft body,
A cover body that covers an upper portion of one end side in the width direction of the traveling machine body is supported so as to be swingable between an action posture and an open posture,
The fuel tank is preferably configured to be switchable to the open position regardless of whether the cover body is in the operating position or the open position.

  According to this configuration, the fuel tank can be switched from the normal use posture to the open posture regardless of whether the cover body that covers the upper side portion on one end side in the width direction of the traveling body is in the working posture or the open posture. It can also be returned to the normal use posture.

  That is, when only the maintenance work in the sorting processing unit is performed instead of the maintenance work in the handling chamber, the work can be performed by switching the fuel tank to the open position while maintaining the cover body in the working position.

  In the present invention, it is preferable that the fuel tank is detachably supported.

  According to this configuration, since the fuel tank can be removed, for example, when the fuel tank is repaired and replaced, the operation can be easily performed. Further, as a maintenance work in the threshing apparatus, when the work needs to be performed with the entire lateral wall portion opened, the work can be easily performed by removing the fuel tank.

The characteristic configuration of the harvester according to the present invention is such that a feeder for transporting a crop harvested in a harvesting section at the front of the aircraft toward the rear side of the aircraft and a fuel tank are aligned in the horizontal direction of the aircraft, and In the state provided with a transmission mechanism for transmitting the power of the engine to the feeder during
The fuel tank is located on one end side in the lateral width direction of the traveling aircraft body, and is provided with a side surface on the outer side in the lateral width direction being exposed laterally outward of the aircraft body.

  According to this configuration, the feeder and the fuel tank are provided in a state of being aligned in the lateral width direction of the fuselage. Further, a transmission mechanism for transmitting engine power to the feeder is provided between the feeder and the fuel tank.

  In this way, the fuel tank is provided in a state of being located on the lateral side of the feeder which is a large-sized device, so that the fuel tank is formed long in the longitudinal direction of the aircraft, for example, so that other fuel tanks are installed on the traveling aircraft. It is possible to increase the size of the fuel tank without adversely affecting the arrangement of the apparatus or increasing the longitudinal length of the traveling machine body.

  The fuel tank is located at one end side in the width direction of the traveling machine body, and the side surface on the outer side in the width direction is exposed to the outer side of the machine body. That is, the fuel tank is located on the outer side in the lateral width direction of the feeder and the transmission mechanism and has a function as an exterior cover.

  As a result, it is possible to use the fuel tank effectively and to reduce the size of the dedicated cover for covering the lateral outer side of the transmission mechanism, or to omit the cover, which simplifies the structure of the exterior part. It becomes possible.

  Therefore, according to the present invention, by improving the arrangement of the fuel tank, it is possible to increase the amount of fuel stored by making the fuel tank large and to simplify the structure of the exterior portion. We were able to provide a possible harvester.

In the present invention, the traveling machine body includes a pair of left and right front traveling devices and a pair of left and right rear traveling devices,
It is preferable that the fuel tank covers a space between the front traveling device and the rear traveling device located on one end side in the body width direction.

  According to this configuration, the fuel tank is provided in a state of covering the space between the front traveling device and the rear traveling device that are located on one end side in the body width direction. That is, it is possible to deploy the fuel tank in a compact manner by effectively using the empty area between the front traveling device and the rear traveling device.

  In the present invention, it is preferable that a work table is formed on the upper surface of the fuel tank.

  According to this configuration, for example, in a case where maintenance work is performed at a high position such as a ceiling part of a threshing device, it is possible for an operator to perform work on a work table formed on the upper surface of the fuel tank, There is an advantage that the work can be performed efficiently without using a special external work table.
