Summary of the Invention

Problems to be Solved by the Invention

[0004] In the harvester described in Patent Document 1, the receiving device is located at a height position lower than the stored grain discharging device. Here, the grain discharging device is usually made of metal. If a metal member is located at a height position above the receiving device, there is a concern that it may adversely affect the reception of the receiving device.

[0005] In view of the above situation, there is a demand for a harvester capable of receiving position information from a satellite well by the receiving device.

Means for Solving the Problems

[0006] The features of the present invention are a harvesting machine comprising: a harvesting unit provided at the front of the machine body, extending across both left and right ends of the machine body for harvesting crops in a field; an operating unit provided at one side of the machine body, behind the harvesting unit; a conveying device provided at the other side of the machine body, next to the operating unit, for conveying the harvested crops toward the rear; a threshing device for threshing the crops conveyed by the conveying device; a grain storage tank for storing the grains obtained by the threshing process of the threshing device; and a grain discharge device for discharging the grains from the grain storage tank, wherein the operating unit is provided above the side on which the conveying device is located in the left-right direction, for receiving positional information from a satellite, and a frame supporting the receiving device, wherein the receiving device is located at a height higher than the grain discharge device when it is stored. A feature of the present invention is that it is provided on one side of the aircraft body, and has a driver's seat and a front panel located in front of the driver's seat. , open to the outside The aircraft comprises an operating unit, a receiving device for receiving position information from a satellite, and a frame for supporting the receiving device. The frame is provided with an inner vertical frame section located on the inner side of the aircraft body in front of the operating unit and extending vertically below the receiving device, a horizontal frame section connected to the inner vertical frame section and extending laterally outward relative to the receiving device, and a front and rear frame section connected to the inner vertical frame section and extending rearward relative to the receiving device. The lower part of the inner vertical frame section is supported by the aircraft body, the horizontal frame section is supported by the aircraft body via an outer vertical frame section extending downward from its outer side end, and the front and rear frame section is supported by the aircraft body via a rear vertical frame section extending downward from its rear end.

[0007] According to this configuration, the receiving device is positioned at a height above the stored grain discharge device. This allows the receiving device to receive positional information from the satellite effectively without being affected by the metal grain discharge device. In other words, it is possible to realize a harvesting machine in which the receiving device can receive positional information from the satellite effectively.

[0008] Furthermore, in the present invention, it is preferable that the frame is supported by a stay to which the receiving device is attached, and that the stay is configured to be repositionable between a usage position in which the receiving device is used and a storage position located at a height lower than the usage position.

[0009] With this feature configuration, when using the receiving device, the mounting bracket can be repositioned to position the receiving device at a height that ensures good reception. Furthermore, when not using the receiving device, or when storing the harvesting machine in a barn or similar location, the mounting bracket can be repositioned to the storage location, lowering the height of the machine relative to the receiving device so that it does not obstruct the view.

[0010] Furthermore, in the present invention, it is preferable that the receiving device is located at a height above the stored grain discharge device when the stay is in the usage position, and at a height below the upper end of the stored grain discharge device when the stay is in the storage position.

[0011] With this feature configuration, when the stay is in the operational position, the receiving device is positioned above the stored grain discharge device. This allows the receiving device to receive positional information from the satellite well without being affected by the metal grain discharge device. Furthermore, when the stay is in the stored position, the receiving device is positioned below the top of the stored grain discharge device. This allows the height of the machine up to the receiving device to be lowered so that the receiving device does not get in the way when the receiving device is not in use or when the harvesting machine is stored in a barn or similar building.

[0012] Furthermore, in the present invention, it is preferable that the frame is equipped with a gate-shaped member having a substantially gate-like shape.

[0013] This feature configuration allows for increased frame rigidity through the use of gate-shaped members.

[0014] Furthermore, in the present invention, it is preferable that the gate-shaped member is formed in a substantially gate-shaped form when viewed from the front, and that the frame is provided with a bracing member that forms a surface intersecting with the surface formed by the gate-shaped member in a plan view, and that supports the gate-shaped member.

[0015] According to this feature configuration, the gantry member is formed in a roughly gantry shape when viewed from the front, making it easy to support the gantry member on both the left and right sides of the driver's unit. Furthermore, the gantry member can be firmly supported by bracing members to prevent it from tipping over in the front-to-back direction.

[0016] Furthermore, in the present invention, it is preferable that the bracing member is formed in a substantially gate-like shape when viewed from the side.

[0017] According to this feature configuration, the rigidity of the frame can be further increased because, in addition to the gate-shaped member, the bracing member is also roughly gate-shaped.

[0018] Furthermore, in the present invention, it is preferable that the receiving device is supported at the intersection of the gate-shaped member and the bracing member within the frame.

[0019] The intersection of the gate-shaped member and the bracing member within the frame is a relatively rigid part of the frame. With this characteristic configuration, the receiving device can be firmly supported by the intersection of the gate-shaped member and the bracing member within the frame. Furthermore, in the present invention, it is preferable that the receiving device is supported at the connecting portion between the inner vertical frame portion and the front and rear frame portions. In this case, it is preferable that the front end of the connecting portion is located in front of the front panel. Furthermore, in the present invention, it is preferable that the receiving device is supported in the intersection region where the inner vertical frame portion, the horizontal frame portion, and the front and rear frame portions intersect. In this case, it is preferable that the intersection region extends to the area in front of the front panel.

[0020] Furthermore, in the present invention, a driving unit frame constituting the driving unit is provided, and the portal member is supported by the driving unit frame at each of the left and right side portions at the front of the driving unit, and the holding member is preferably supported by the driving unit frame at the left and right central portions at the rear of the driving unit.

[0021] According to this characteristic configuration, the portal member and the holding member can be supported by the driving unit frame in a state with good balance in the front-rear direction and the left-right direction. In addition, the driving unit preferably has a side panel located inside the fuselage widthwise relative to the driver's seat, and the inner vertical frame portion is supported by a side panel frame that supports the side panel. Also, an engine room is provided below the driving unit, and an engine bonnet is provided that covers the engine room and mounts and supports the driver's seat. The rear vertical frame portion is preferably supported by the engine bonnet at the left and right central portions at the rear of the driving unit.

[0022] Furthermore, in the present invention, a canopy that covers the driving unit from above is provided. The portal member and the holding member are arranged outside the driving unit with respect to the canopy in a plan view. The canopy is configured to be vertically movable over a use position located at a height position above the upper end portion of the frame and a storage position located at a height position below the upper end portion of the frame.

[0023] According to this characteristic configuration, the canopy can be vertically moved over the use position and the storage position without interfering with the portal member and the holding member.

[0024] Furthermore, in the present invention, the portal member is provided with vertical frame portions erected on both the left and right sides of the front portion of the operation unit, and a horizontal frame portion provided across the upper end portions of the left vertical frame portion and the right vertical frame portion. It is preferable that the left and right vertical frame portions are erected in a forward-tilted posture.

[0025] According to this characteristic configuration, the horizontal frame portion will be located in front of the base portions of the vertical frame portions on both the left and right sides. As a result, when the driver looks down at the front lower part of the operation unit in a forward-tilted posture, a wide space can be ensured between the head and the horizontal frame portion so that the head is less likely to come into contact with the horizontal frame portion. In the present invention, it is preferable that the inner vertical frame portion and the front-rear frame portion are located within the width range of the receiving device in the left-right direction of the machine body in a state where the receiving device is being used. In the present invention, a stay for connecting the frame and the receiving device is provided. The connecting portion between the inner vertical frame portion and the horizontal frame portion is located within the width range of the receiving device in the left-right direction of the machine body in a state where the receiving device is being used, and is preferably located within the vertical width range of the stay in the up-down direction. In the present invention, it is preferable that the outer vertical frame portion is supported by the lateral outer portion of the front panel of the machine body. In the present invention, it is preferable that the receiving device is arranged at a position overlapping the front-rear width range of the front panel in the front-rear direction of the machine body.
