刈取収穫機に関する。[Detailed description of the invention] The present invention is a reaping device in which a lifting reaping section is attached to the free end of a frame that can be operated to vertically swing relative to the vehicle body and a transmission mechanism for the lifting reaping section is installed inside. Regarding harvesting machines.

なる不都合があつた。 The above-mentioned reaping harvester has a lifting reaping section that can swing up and down relative to the vehicle body, so when crossing ridges, etc., the reaping section is raised greatly and pulled up, allowing the reaping section to contact the ridge, etc. In addition, even if the vehicle body sinks into the mud when working in wet fields, it is designed to maintain the reaping section at the appropriate reaping height above the field surface. . However, when working in wet fields, the attitude of the reaping unit toward the rice field is tilted backwards rather than the proper attitude, resulting in a disadvantage that lowering performance and cutting performance at the base of stems and culms occur. To elaborate further,
In general, when working in dry fields where the vehicle body does not sink into mud, the structure is such that when the hoisting reaping section is lowered to the appropriate cutting height, the attitude of the hoisting reaping section toward the rice field becomes the appropriate posture. As a result, the higher the reaping part is raised, the more it tends to fall backwards.Moreover, when working in wet fields, for example, if the vehicle body is equipped with a crawler traveling device, the front end of the crawler traveling device may be exposed to muddy soil. The vehicle body tends to fall backwards due to the fact that it rotates while pushing down, and the mud presses the front end of the crawler traveling device upwards as it advances. There was an inconvenience that the team's posture toward the field was tilted far back than the appropriate posture.
尚、上記不都合は、車体の前後部夫々に車輪を
備えた場合にも生じるものである。 Incidentally, the above-mentioned inconvenience also occurs when wheels are provided at the front and rear of the vehicle body, respectively.

があり、実用し難いものであつた。 In order to solve the above-mentioned inconvenience, conventionally, the lifting reaping part is pivoted to a frame that can be operated up and down relative to the vehicle body so as to be swingable back and forth, and the lifting reaping part is provided between the lifting reaping part and the frame. A method of installing a drive mechanism such as a hydraulic cylinder to swing the reaping section has been proposed, but this method has the disadvantage of requiring an expensive drive mechanism and the need to operate the drive mechanism at the appropriate time to raise and swing the reaping section. It was difficult to put it into practical use because it required manual operation.
そこで、従来は、特別な操作を要しない構造

に開示された刈取収穫機が知られていた。 Therefore, conventionally, a method was developed that did not require any special operation and was designed to maintain the proper posture of the reaping section toward the rice field even during wet paddy work. A reaping harvester disclosed in Japanese Utility Model Application Publication No. 56-64245 was known.

するとともに、車体に、前記腰折れリンクに接当
するストツパーを設けて、前記引起し刈取部を、
設定高さよりも上方範囲において上昇させるに従
つて後方側に揺動させるべく構成してある。 In the conventional device described above, the lifting reaping section is connected to the vehicle body via a pair of upper and lower parallel links, and the lifting reaping section is raised and lowered in parallel. The vehicle body is configured to swing forward as it is raised, and its upper link is configured to be bendable, and a stopper is provided on the vehicle body that abuts the bending link. The reaping part,
It is configured to swing rearward as it is raised in a range above the set height.

う不都合があり、さらに、引起し刈取部に対する
伝動構造は、自在継手や伸縮自在な伝動軸を用い
た複雑な伝動機構を介して別途に行わなければな
らないという不都合もあつた。 However, in this type of device that changes the posture of the lifting and reaping section above a set height by contacting the link with the stopper, a large impact force is applied at the time of contact. It is necessary to provide a stopper large enough to withstand the damage, and there is also the inconvenience that one of the parts will be worn out and damaged with long-term use, making it necessary to replace the part. The transmission structure also had the disadvantage of having to be constructed separately via a complicated transmission mechanism using a universal joint or a telescopic transmission shaft.

姿勢をほぼ一定にするものである。 On the other hand, in the conventional reaping harvester described above, the lifting reaping part is vertically swingably supported on the free end of the frame which is pivotally supported to the vehicle body so as to be vertically swingable. By providing a link between a part near the pivot point with the reaping part and a part near the hydraulic cylinder for vertically swinging the frame, the hydraulic cylinder is extended and pulled up to raise the reaping part. Accordingly, the raising and reaping section is tilted forward with respect to the frame, so that the posture of the raising and reaping section toward the field surface is kept almost constant.

難しいという欠点があつた。 However, in the conventional reaping and harvesting machine described above, the distance between the part near the pivot of the frame and the pulling reaping part and the part near the hydraulic cylinder is kept constant by the link, and the pulling reaping part is Since the part is pivotally supported to the frame so as to be able to swing up and down, the attitude of the lifting and reaping part towards the rice field remains almost constant. This means that it is held almost constant, and with this structure, it is difficult to raise the reaping part significantly when crossing a ridge or the like.

てあることを特徴構成とするものである。 In order to achieve the above object, the reaping/harvesting machine according to the present invention has a lifting reaping section attached to the free end of a frame capable of vertically swinging operation relative to the vehicle body, which is equipped with a transmission mechanism for the lifting reaping section. In the reaping harvester, the pulling reaping section is pivoted to the frame so as to be swingable back and forth and up and down around a horizontal axis, and the upper side of the lifting reaping section is connected to the frame through a single link. The lifting and reaping section is pivotally connected to the vehicle body, and the position of the pivot connection point and the length of the link with respect to the vehicle body are such that the raising and reaping portion increases as the frame is raised within a range below a set height relative to the vehicle body. The pulling and reaping section is moved rearward and upward relative to the frame so as to swing forward and downward relative to the frame, and as the frame is raised within a range above the set height relative to the vehicle body. It is characterized by being set so that it can be swung back and forth.

は大きく上昇する姿勢に変更される。 In other words, by providing the link on the upper side of the lifting reaping part, rather than in the vicinity of the pivot point between the lifting reaping part and the frame, vertical swinging of the frame below the set height relative to the vehicle is prevented. In the movement,
As the frame rises, the link can be changed to a position where the upper part of the reaping section is pushed forward, and the reaping section is rotated forward and downward around the horizontal axis relative to the frame. The posture on the ground can be kept almost constant, and when the frame is vertically swung above the set height of the frame relative to the vehicle body, the link can be raised as the frame rises, and the upper part of the reaping section can be changed to a posture that is pulled rearward. Since the lifting reaping section is rotated backward and upward relative to the frame around the horizontal axis, the lifting reaping section is changed to a posture in which it is greatly raised as the frame rises.
