Description

Technology Field

[0001] The present invention relates to a harvester equipped with a receiving device for receiving position information from a satellite and a frame for supporting the receiving device.

[0002] In addition, the present invention relates to a harvester equipped with a driver's seat and a driver's section having a front panel located in front of the driver's seat. Background Technology

[0003] As a harvester as described above, for example, the harvester described in Patent Document 1 is already known. The harvester described in Patent Document 1 is equipped with a receiving device for receiving position information from a satellite (in the document, "positioning unit

[100] "), a frame for supporting the receiving device (in the document, "support frame

[112] "), and a grain discharge device for discharging grains from a grain storage tank (in the document, "grain tank

[61] ") (in the document, "discharge auger

[61] ").

[0004] In addition, as a harvester as described above, for example, the harvester described in Patent Document 2 is already known. The harvester described in Patent Document 2 is equipped with a driver's seat (in the document, "driver's seat

[12] ") and a driver's section having a front panel located in front of the driver's seat (in the document, "control tower

[14] "). Prior art literature

[0005] Japanese Patent Publication No. 2018-77174 and Japanese Patent Publication No. 2017-131237 The problem to be solved

[0006] In the harvester described in Patent Document 1, the receiving device is located at a height lower than the grain discharge device in a stored state. Here, since the grain discharge device is typically made of metal, if the metal member is located at a height higher than the receiving device, there is a concern that it will have an adverse effect on the receiving device.

[0007] In light of the above situation, a harvesting period is desired in which the receiving device can receive position information from the satellite well.

[0008] In addition, the harvester described in Patent Document 1 does not consider detaching the frame from the body when the receiving device is not in use or when the harvester is stored in a barn, etc., or installing the frame on the body when the receiving device is later installed on the harvester.

[0009] In light of the above situation, a harvester suitable for detaching the frame supporting the receiving device from the body or installing it on the body as needed is desired.

[0010] In addition, in the harvester described in Patent Document 2, when the driver sees the situation in the forward and downward direction from the driver's seat, the view is easily obstructed by the upper part of the front panel.

[0011] In light of the above situation, a harvesting device capable of improving visibility when the driver perceives the situation in front and below from the driver's seat is desired. means of solving the problem

[0012] The feature of the present invention is a harvester having a harvesting unit that is provided across both left and right ends of the front part of the machine and harvests crops from packaging, a driving unit provided at the rear of the harvesting unit at a location on one side of the left and right of the machine, a conveying device provided at the side of the driving unit at the other side of the machine and conveys the harvested crops toward the rear, a threshing device that threshs the crops conveyed by the conveying device, a grain storage tank that stores grains obtained by the threshing process of the threshing device, and a grain discharge device that discharges grains from the grain storage tank, and a receiving device provided at the upper side of the side where the conveying device is located in the left and right direction of the driving unit and receiving position information from a satellite, and a frame that supports the receiving device, wherein the receiving device is located at a height position higher than the grain discharge device in a stored state.

[0013] According to the configuration of the present feature, the receiving device is positioned at a height above the grain discharge device in its stored state. As a result, the receiving device can receive position information from the satellite well without being affected by the metal grain discharge device. In other words, a harvester capable of receiving position information from the satellite well can be realized.

[0014] In addition, in the present invention, a stay is provided that is supported by the frame and on which the receiving device is installed, and the stay is configured to be repositionable between a usage position where the receiving device is used and a storage position located at a height lower than the usage position.

[0015] According to the configuration of this feature, when the receiving device is in use, the receiving device can be positioned at a height where reception is good by changing the position of the stay to the usage position. Additionally, when the receiving device is not in use or when the harvester is stored in a barn, the height of the machine to the receiving device can be lowered so that the receiving device is not obstructed by changing the position of the stay to the storage position.

[0016] In addition, in the present invention, the receiving device is positioned at a height above the grain discharge device in the stored state when the stay is positioned at the usage position, and is positioned at a height below the top of the grain discharge device in the stored state when the stay is positioned at the storage position.

[0017] According to the configuration of the present feature, when the stay is in the usage position, the receiving device is positioned at a height higher than the grain discharge device in the stored state. As a result, the receiving device can receive position information from the satellite well without being affected by the metal grain discharge device. Additionally, when the stay is in the storage position, the receiving device is positioned at a height lower than the top of the grain discharge device in the stored state. As a result, when the receiving device is not in use or when the harvester is stored in a barn, the height of the unit to the receiving device can be lowered so that the receiving device does not become an obstruction.

[0018] In addition, in the present invention, it is suitable if the frame is provided with a gantry-shaped member having a roughly gantry shape.

[0019] According to the configuration of this feature, the rigidity of the frame can be increased by the gantry member.

[0020] In addition, in the present invention, the gantry member is formed in a roughly gantry shape when viewed from the front, and the frame is provided with a bracing member that supports the gantry member and forms a plane that intersects the plane formed by the gantry member when viewed from a plane.

[0021] According to the configuration of this feature, since the gantry member is formed in a roughly gantry shape when viewed from the front, it is easy to support the gantry member on both the left and right sides of the operating section. In addition, the gantry member can be securely supported by bracing members so that it does not tip over in the front-rear direction.

[0022] In addition, in the present invention, the bracing member is suitable if it is formed in a roughly gantry shape when viewed from the side.

[0023] According to the configuration of this feature, in addition to the gantry-shaped member, the bracing member has a roughly gantry-shaped form, thereby further increasing the rigidity of the frame.

[0024] In addition, in the present invention, the receiving device is suitable if it is supported at the intersection of the gate-shaped member and the bracing member in the frame.

[0025] The intersection of the gantry member and the bracing member within the frame is a part of the frame with relatively high rigidity. According to the configuration of this feature, the receiving device can be securely supported by the intersection of the gantry member and the bracing member within the frame.

[0026] In addition, in the present invention, a driving unit frame constituting the driving unit is provided, and the gantry member is supported by the driving unit frame at each of the left and right sides in the front part of the driving unit, and the bracing member is supported by the driving unit frame at the left and right center parts in the rear part of the driving unit.

[0027] According to the configuration of this feature, the gantry member and bracing member can be supported on the driver's frame in a state of good balance in the front-rear and left-right directions.

[0028] In addition, in the present invention, a canopy covering the driving unit from above is provided, and the gantry member and the bracing member are positioned outside the driving unit relative to the canopy when viewed in a planar view, and the canopy is configured to be vertically movable across a usage position located at a height above the upper end of the frame and a storage position located at a height below the upper end of the frame.

[0029] According to the configuration of this feature, the canopy can be moved up and down between the usage position and the storage position without interfering with the door-type member and the bracing member.

[0030] In addition, in the present invention, the above-described gantry member is provided with a longitudinal frame section installed upright on each of the left and right sides in the front part of the driving part, and a transverse frame section provided across the upper part of the left longitudinal frame section and the upper part of the right longitudinal frame section, and the left and right longitudinal frame sections are installed upright in a forward inclined position.

[0031] According to the configuration of this feature, the transverse frame section is positioned further forward than the base of the longitudinal frame sections on both the left and right sides. As a result, when the driver looks down at the front and lower part of the driver's seat in a forward-tilted posture, a wide space can be secured between the head section and the transverse frame section so that the head section is unlikely to come into contact with the transverse frame section.

[0032] In addition, a feature of the present invention is that it is equipped with a receiving device for receiving position information from a satellite and a frame for supporting the receiving device, wherein the frame is configured to be detachably attached to a body.

[0033] According to the configuration of the present feature, the frame is configured to be detachable from the machine. Therefore, when the receiving device is not in use or when the harvester is stored in a barn, the frame can be easily removed from the machine. In addition, when the receiving device is to be mounted on the harvester later, the frame can be easily installed on the machine. In other words, it is possible to realize a harvester suitable for detaching the frame supporting the receiving device from the machine or installing it on the machine as needed.

[0034] In addition, in the present invention, the frame is configured to be divisible into a plurality of frame members.

[0035] According to the configuration of the present feature, when attaching or detaching the frame, the frame is divided into multiple frame members and handled, thereby making the attachment and detachment of the frame easier than when the entire frame is handled as a single unit.

[0036] In addition, in the present invention, the frame is provided with, as a frame member, a gantry member having a roughly gantry shape and a bracing member supporting the gantry member, and the frame is configured to be divisible into the gantry member and the bracing member.

[0037] According to the configuration of the present feature, the rigidity of the frame can be increased by the gantry member, while the gantry member can be reliably supported by the bracing member. In addition, when attaching or detaching the frame, by handling the frame by dividing it into the gantry member and the bracing member, the attachment and detachment of the frame can be performed more easily than when the entire frame is handled as a single unit.

[0038] In addition, in the present invention, the frame member is suitable if it is composed of a member located on one surface or two intersecting surfaces.

[0039] According to the configuration of this feature, the shape of the frame member is simplified. As a result, the handling of the frame member can be improved during the attachment and detachment of the frame.

[0040] In addition, in the present invention, the frame is provided with a plurality of installation parts installed on the body, and the plurality of installation parts are configured to be installed from different directions relative to the body.

[0041] For example, if all of the multiple installation parts are configured to be installed from the same direction relative to the body, the frame is prone to detaching from the body if the direction of the external force acting on the frame is opposite to the installation direction of the installation part (detachment direction). However, according to the present feature configuration, even if the direction of the external force acting on the frame coincides with the detachment direction of some of the installation parts, the direction of the external force acting on the frame does not coincide with the detachment direction of all installation parts, so the frame is prone to detaching from the body.

[0042] In addition, the present invention is suitable for a driving unit having a driver's seat and a front panel located in front of the driver's seat, and for a frame to be provided along the lateral side of the front panel while extending along the vertical direction.

[0043] According to the configuration of the present feature, by aligning the part of the frame that extends along the vertical direction with the lateral side of the front panel, the part of the frame that extends along the vertical direction is less likely to interfere with the driver, and at the same time, the frame can be installed on the aircraft in a stable state.

[0044] In addition, the present invention is suitable if a driving unit having a driver's seat and a side panel located laterally to the driver's seat is provided, and the frame is supported by a side panel frame that supports the side panel.

[0045] According to the configuration of the present feature, the side panel frame can be used as a member supporting the frame.

[0046] In addition, in the present invention, a driving unit having a driver's seat is provided at a location on either the left or right side of the body, and the frame is provided with an inner frame member extending to a rear side of the driver's seat through the inner side of the body transversely relative to the driver's seat, a transverse frame member extending from the rear end of the inner frame member toward the outer side of the body transversely through the rear of the driver's seat, and a longitudinal frame member that is installed upright on the driving unit frame of the driving unit while extending along the vertical direction and supports the transverse frame member.

[0047] According to the configuration of the present feature, the inner frame member and the transverse frame member pass through the transverse inner side of the aircraft and the rear of the aircraft with respect to the driver's seat. As a result, the inner frame member and the transverse frame member can be positioned using the space on the side or rear of the transverse inner side of the aircraft in the driver's section so as not to interfere with the driver. In addition, the transverse frame member is supported by the driver's section frame, which has relatively high rigidity, through the longitudinal frame member. As a result, the transverse frame can be reliably supported.

[0048] In addition, in the present invention, a receiving portion for accommodating electrical components is provided at the rear of the driver's seat in the driving portion, and a longitudinal frame member is provided inside the receiving portion, and the longitudinal frame member is configured to be divisible vertically.

[0049] According to the configuration of the present feature, the longitudinal frame member can be positioned inside the receiving section without interfering with the driver. Additionally, the receiving section can be reinforced by the longitudinal frame member. Furthermore, when installing the longitudinal frame member inside the receiving section or removing it from the receiving section, by handling the longitudinal frame member by dividing it vertically, the attachment and detachment of the longitudinal frame member can be performed more easily than when the longitudinal frame member is handled as a single unit.

[0050] In addition, in the present invention, the inner frame member and the transverse frame member are preferably connected in such a way that they can be disconnected by a connecting part.

[0051] According to the configuration of the present feature, when attaching and detaching the inner frame member and the transverse frame member, by handling them in a state where the inner frame member and the transverse frame member are disconnected, the attachment and detachment of the inner frame member and the transverse frame member can be performed more easily than when the inner frame member and the transverse frame member are handled as a single unit.

[0052] In addition, in the present invention, the connecting portion is provided with a first stay provided in the inner frame member and a second stay provided in the transverse frame member, and it is suitable if the inner frame member and the transverse frame member are connected by the connecting portion while the first stay and the second stay are in surface contact.

[0053] According to the configuration of this feature, the inner frame member and the transverse frame member can be securely connected.

[0054] In addition, the feature of the present invention is that a driver's seat and a driver's unit having a front panel located in front of the driver's seat are provided, and a recess is formed on the upper part of the front panel, which is concave downward with a width wider than the width of the driver's seat, the upper end of the recess is located at a height position higher than the seat surface of the driver's seat, and the lower end of the recess is located at a height position lower than the seat surface of the driver's seat, and a handle is provided that extends from a height position lower than the upper end of the recess and extends along the left and right directions from a height position higher than the upper end of the recess, in the recess area of ​​the recess with respect to the driver's seat when viewed from the front.

[0055] According to the configuration of the present feature, the upper part of the front panel is deeply recessed over a width wider than the width of the driver's seat, and also over a height position above the seat surface of the driver's seat and a height position below the seat surface of the driver's seat. As a result, the driver can clearly see the situation in front and below the driver's seat through the recessed part without obstructing their view of the upper part of the front panel. In other words, it is possible to realize a harvester capable of improving visibility when the driver sees the situation in front and below from the driver's seat.

[0056] In addition, it is easy for the driver to stabilize their posture by gripping the steering wheel. Here, the part of the steering wheel extending along the left and right directions is positioned at a height higher than the top of the recessed section. As a result, even when the driver is standing, it is easy to reach the part of the steering wheel extending along the left and right directions, while the driver can be protected from the front by this part of the steering wheel extending along the left and right directions. Furthermore, since the distance between the upright parts on both sides of the steering wheel is wider than the width of the driver's seat, the base of the steering wheel becomes stable. This improves the stability of the steering wheel.

[0057] In addition, in the present invention, the driving unit is provided at a location on one side of the left or right of the machine, and at a location on the other side of the left or right of the machine, a conveying device for conveying harvested crops toward the rear is provided on the side of the driving unit, and on each of the left and right sides of the recessed part, an inclined part is formed such that it is positioned at a height position on the upper side as it is spaced away from the left and right center of the recessed area, and among the left and right inclined parts, the inclined part on the side where the conveying device is located is suitable if the angle formed with the vertical line within the recessed area is greater than the inclined part on the side opposite to the side where the conveying device is located.

[0058] According to the configuration of the present feature, the inclined portion on the side where the conveying device is located forms a larger angle with the vertical line within the recessed area than the inclined portion on the side opposite to where the conveying device is located. Accordingly, in the recessed area, the lateral width of the area above the inclined portion on the side where the conveying device is located is made wider than the lateral width of the area above the inclined portion on the side opposite to where the conveying device is located, so that the operator can see the status of crop conveying by the conveying device over a wide range through the area above the inclined portion on the side where the conveying device is located within the recessed area from the operating unit. Furthermore, when forming a portion (recessed portion) for the conveying device to enter in the part of the front lower portion of the operating unit on the side where the conveying device is located, it is suitable to form the said recessed portion large in order to allow the conveying device to enter as deeply as possible toward the left and right center of the operating unit.

[0059] In addition, in the present invention, the driving unit is provided with a side panel located on the lateral side of the driver's seat, a steering control device for steering the aircraft, and a meter panel, and the side panel and the steering control device are allocated and arranged on the left and right sides and the other sides of the driving unit, respectively, and the meter panel is located between the side panel and the steering control device, and is also positioned above the recessed portion when viewed from the front, in a state independent from the side panel and the steering control device.

[0060] According to the configuration of this feature, a meter panel can be placed between the left and right sides of the side panel and the steering mechanism, and also by utilizing the space above the recess when viewed from the front.

[0061] In addition, in the present invention, it is suitable if the handle is configured to be positioned so as to be placed above the meter panel when viewed from the front.

[0062] According to the configuration of this feature, the part of the steering wheel extending along the left and right directions is positioned at a height higher than the meter panel. As a result, when the driver grips the part of the steering wheel extending along the left and right directions, the meter panel is unlikely to interfere.

[0063] In addition, in the present invention, the handle is suitable if it extends along the left-right direction when viewed from a plane at a position forward of the front end of the meter panel.

[0064] According to the configuration of this feature, the driver can clearly see the meter panel without their view being obstructed by the steering wheel.

[0065] In addition, in the present invention, it is suitable for the handle to be located on the forward side compared to the front end of the steering mechanism.

[0066] According to the configuration of this feature, when the driver looks down at the front and bottom of the driver's unit while operating the steering controls, it is easy to grip the steering wheel.

[0067] In addition, in the present invention, a frame supporting the meter panel is provided in the upper and lower middle portions of the front panel in a state extending along the left and right directions, and the handle is supported by the frame.

[0068] According to the configuration of the present feature, the frame supporting the meter panel can be used as a member supporting the handle. Additionally, since the frame is provided to extend along the left and right directions, it is suitable for supporting the upright parts on both the left and right sides of the handle.

[0069] In addition, in the present invention, it is suitable if a transparent cover is provided in front of the handle in the recessed area.

[0070] According to the configuration of the present feature, the driver can be protected from the front (e.g., from flying dust) while maintaining good visibility of the driver's front and lower portion through a transparent cover. Brief explanation of the drawing
