Description

  The present invention relates to a combine provided with a fuselage frame supported by a traveling device.

  For example, the following patent document 1 describes a conventional combine. The combine includes a body frame supported by a traveling device (“front wheel” and “rear wheel” in Patent Document 1), a driving unit (“Engine” in Patent Document 1) supported by the body frame, and a body frame. A transmission mechanism ("Transmission" and "Front Wheel Drive Case" in Patent Document 1) that is coupled and supported by the front part of the vehicle and transmits the power of the driving part to the traveling device, and a horizontal axis around the horizontal direction of the machine body at the front part of the traveling machine body And a cutting portion provided so as to be movable up and down.

  The airframe includes a pair of left and right main frames extending in the front-rear direction of the airframe (referred to as “front-rear facing frame body” in Patent Document 1), and extending in the horizontal direction of the airframe and positioned in front of the transmission mechanism. A horizontal frame body [18a] for connecting the front ends of the main frame, and a horizontal frame body for connecting the left and right main frames at the rear of the horizontal frame body [18a] in a state of being positioned below the transmission mechanism [ 18b]. The horizontal frame body [18b] supports a hydraulic cylinder ("cutting lift cylinder" in Patent Document 1) that drives the cutting part to move up and down.

JP2013-158258A (FIGS. 10 and 11)

However, in the technique described in Patent Document 1, for example, the horizontal frame body [18b] is arranged at a height position overlapping with the transmission mechanism, so that the hydraulic cylinder is arranged with respect to the horizontal frame body [18b]. In the lateral direction of the fuselage, it was constrained to a location that did not overlap with the transmission mechanism.
Further, for example, in order to avoid interference between the hydraulic cylinder and the lateral frame body [18a], a cylinder bracket for attaching the hydraulic cylinder to the lateral frame body [18b] is changed from the lateral frame body [18b] to the lateral frame body [18b]. 18a] had to be of a special specification long in the longitudinal direction of the airframe extending to a position directly below. In addition, in order to reinforce the cylinder bracket that is long in the longitudinal direction of the fuselage, a plurality of reinforcing members are required. For this reason, the structure is complicated.

  In view of the above situation, it has been desired to provide a combine having a frame structure in which a hydraulic cylinder for raising and lowering a mowing part can be suitably arranged and a complicated structure is avoided.

  The characteristic configuration of the combine according to the present invention includes: a body frame supported by a traveling device; a prime mover supported by the fuselage frame; and a front part of the fuselage frame coupled to and supported by the travel of the power of the prime mover A power transmission mechanism that transmits to the device, a cutting part that can be moved up and down around a horizontal axis centered horizontally in the front of the traveling machine body, and a hydraulic cylinder that drives the cutting machine to move up and down. A pair of left and right main frames extending along the longitudinal direction of the fuselage, and a first lateral connecting the front ends of the left and right main frames in a state extending along the lateral direction of the fuselage and positioned below the transmission mechanism. And the hydraulic cylinder is supported by the first horizontal frame.

According to the present invention, the front end portions of the left and right main frames extending along the longitudinal direction of the fuselage are connected to each other by the first lateral frame extending along the lateral direction of the fuselage while being positioned below the transmission mechanism. The horizontal frame supports a hydraulic cylinder that drives the mowing unit up and down. That is, when the hydraulic cylinder is supported on the first horizontal frame, the transmission mechanism does not get in the way, and the hydraulic cylinder can be arranged at an arbitrary position of the first horizontal frame in the horizontal direction of the machine body.
And since the 1st horizontal frame has connected the front-end parts of the left and right main frames, the member which connects the left and right main frames does not exist ahead of the first horizontal frame. That is, the cylinder bracket for attaching the hydraulic cylinder to the first horizontal frame can be of a normal specification that is not so long in the front-rear direction. In addition, since the cylinder bracket for normal specifications can be used, a reinforcing member for reinforcing the cylinder bracket is not required. Therefore, complication of the frame structure can be avoided.
Therefore, according to the present invention, it is possible to suitably arrange the hydraulic cylinder that drives the reaping portion up and down, and it is possible to configure a combine having a frame structure that avoids complicated structure.

  In the present invention, it is preferable that the first horizontal frame connects corners at lower front ends of the left and right main frames.

  According to this configuration, since the corner portions at the lower front ends of the left and right main frames are connected by the first horizontal frame, the connection strength of the first horizontal frame with respect to the left and right main frames can be increased.

  In the present invention, it is preferable that the transmission mechanism is connected to an upper portion of the main frame.

  According to this configuration, since the transmission mechanism is coupled to the upper part of the main frame, the transmission mechanism can be stably supported from below by the main frame.

  In the present invention, there is provided a transmission support frame that is connected to each of the left and right main frames and disposed at a position higher than the main frame, and the upper part of the transmission mechanism is connected to the transmission support frame, and The lower part of the transmission mechanism is preferably connected to the main frame.

  According to this configuration, the transmission mechanism can be sandwiched vertically by the left and right transmission support frames and the left and right main frames and stably supported. Since the left and right main frames, the transmission mechanism, and the left and right transmission support frames are connected to each other, the transmission mechanism functions as a rigid member in the frame structure, and the frame structure has high robustness as a whole. be able to.

  In the present invention, it is preferable that a second horizontal frame that extends along the horizontal direction of the machine body and connects the left and right transmission support frames is provided.

  According to this configuration, since the left and right transmission support frames are connected to each other by the second horizontal frame extending along the horizontal direction of the machine body, a frame structure that is resistant to the force from the horizontal direction of the machine body can be obtained.

  In the present invention, an operation cabin and a cabin frame that supports the operation cabin from below are provided, and a cabin support frame that is erected from the left and right transmission support frames on the cabin frame, and a lateral direction of the fuselage. It is preferable that a connecting horizontal frame that extends along the left and right and connects the left and right cabin support frames is provided.

  According to this configuration, the cabin frame has a structure in which the cabin support frames that are erected from the left and right transmission support frames are connected to each other by the connection horizontal frame that extends along the aircraft horizontal direction. This makes it possible to construct a cabin frame that is strong against the force from. Thus, the cabin can be stably supported from below by the cabin frame.

  In the present invention, it is preferable that a reinforcing frame that connects the main frame and the cabin support frame and a fender that covers the traveling device are provided, and the fender is supported by the reinforcing frame.

  According to this configuration, since the main frame and the cabin support frame are connected by the reinforcing frame, a frame structure having high rigidity as a whole can be obtained. And since the fender which covers a traveling apparatus is supported using this reinforcement frame, while being able to aim at sharing of a member, it can support a fender stably.
