Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a mowing pretreatment device having a first mowing device for cutting the tips of planted grain culms is movably connected to the front part of a traveling machine equipped with a threshing device. A second cutting device, which cuts the stubble stumps left uncut by the first cutting device to a predetermined length, is placed at the lower part of the installation and is used downward while being positioned on the rear side of the fuselage with respect to the first cutting device. This is an all-cullet-type combine combine that can be switched to the upper storage position.

[0002]

[Prior Art]

 Conventionally, the clutch of the second reaping device of the all culm throw type combine has been artificially turned on and off.

[0003]

[Problems to be solved by the device]

 When turning the aircraft at the edge of the field, various operations such as disengaging the steering clutch, raising the pre-mowing treatment device, and moving the traveling device forward and backward are complicated. At times, the clutch of the second reaper was often forgotten, which was dangerous. Therefore, the clutch of the second reaping device is linked to the lifting lever of the reaping preprocessing device through a linkage mechanism such as a wire so that the clutch of the second reaping device is linked with the raising operation of the preparatory processing device. It is conceivable that the switch can be turned off, but in such a case, there is a disadvantage that the operation of the elevating lever becomes heavy. An object of the present invention is to prevent forgetting to disengage the clutch of the second mowing device when the machine is turning with the mowing pretreatment device being raised, without causing inconvenience such as lever operation of other devices becoming heavy.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention for achieving the above object is to provide an operating mechanism capable of automatically disengaging the clutch of the second mowing device when the mowing pretreatment device is displaced upward from the set height. There is a point.

[0005]

[Action]

When the machine is turning at the end of the field, as shown in FIGS. 1 and 2, when the cutting pretreatment device A is raised around the horizontal axis P ₁ , the rod 15a pivotally supported by the airplane and the lower part of the pretreatment device A are cut. The L-shaped arm 15b of the operating mechanism 15 including the pivotally supported L-shaped arm 15b kicks the tension arm 11a of the belt tension clutch 11 as a cutting clutch for the second cutting device 9 to disengage the tension clutch.

[0006]

[Effect of the device]

 As a result of the above configuration, it is possible to prevent forgetting to disengage the clutch of the second mowing device when the machine is turning with the mowing pretreatment device being raised, without causing inconvenience such as lever operation of other devices becoming heavy.

【Example】

As shown in FIG. 5, in the front part of the traveling machine body 2 in which the threshing device 1 is mounted, the pre-mowing treatment device A is provided via the hydraulic cylinder 3 so as to be vertically movable around the horizontal axis P _1, and all culm throwing type The combine is configured. The pre-cutting device A is a rotary reel 4 that scrapes planted culms toward the machine side, a first reaping device 5 that cuts the tips of the culms, and conveys the ears of the trimmed culms backward. Conveyor 6, auger 7 that collects the grain culms that have been conveyed by the conveyor 6 in the center, a central conveyor 8 that scrapes and conveys the grain culm that is gathered in the center by the auger 7 and sends all the culms to the threshing device 1 and the like It is configured with. A second mowing device 9 for cutting the stubble stump left uncut by the first mowing device 5 to a predetermined length is provided below the first mowing device 5 below the first mowing device 5. It is deployed in a state of being located on the side. In this way, only the grain-grained portion of the grain culm is conveyed to the threshing device 1 to improve the threshing treatment efficiency, and the stump height is reduced to facilitate the plowing work.

As shown in FIGS. 1 and 2, the second mowing device 9 includes a pair of left and right support arms 10, which are pivotally supported on the lower part of the mowing pretreatment device A so as to be swingable around a horizontal axis P ₂ . It is attached to the tip of 10 and can be switched between a use posture that is positioned below and a storage posture that is positioned above via the electric cylinder C. Therefore, if the position of the second mowing device 9 is changed to the retracted position and the mowing pretreatment device A is lowered, the first mowing device 5 mows the root part of the planted culm to perform a one-step mowing. When the cutting pretreatment device A is raised and the second cutting device 9 is lowered to the working posture, the first cutting device 5 cuts the tip portion of the planted culm, and then, The second cutting device 9 can perform two-step cutting in which the stem-and-plant stumps left uncut are cut into a predetermined length. As shown in FIG. 3, the second reaping device 9 changes the rotational movement of the drive pulley 8 a of the central conveyor 8 from the belt tension clutch 11, the belt transmission 12, and the belt transmission 12 into left and right reciprocating movements. As shown in FIG. 1 and FIG. 2, the cutting blade crank 9a is driven by reciprocating left and right through a transmission device 13 for converting rotational motion for conversion.

As shown in FIGS. 1 and 2, a belt tension clutch 11 as a harvesting clutch of the second harvesting device 9 includes a tension arm 11 a pivotally supported around a horizontal axis P ₃ and a tension spring 11 a. In the state where the first reaping device 5 and the second reaping device 9 are constantly urged toward the entry side by the two-step reaping work, when the machine body turns at the end of the field, increasing the processor a further operating mechanism 15 consisting of a rod 15a which is pivotally supported on the body, the L-shaped arm 15b which is pivotally supported rotatably in the horizontal axis P ₄ around the bottom of the pretreatment device a reaper The belt tension clutch 11 is configured to be automatically disengaged via the. Further, the belt tension clutch 11 of the second reaping device 9 is operated by moving the reaping clutch lever 16 provided in the control section upward so that the wire 17 and the swinging arm provided coaxially with the L-shaped arm 15b. The other end of the tension arm 11a is kicked upward via the hole 18 to allow an artificial cutting operation. The mowing pretreatment device A is configured to be able to move up and down within a range of 26 °, and within a range of 0 to 5 °, the belt tension clutch 11 of the second mowing device 9 is disengaged by operating the mowing clutch lever 16. The first mowing device 5 can perform the first-step cutting work, and in the range of 5 to 15 °, the cutting of the belt tension clutch 11 by the cutting clutch lever 16 can be released to perform the second-step mowing work, and the 15-26 ° range. In the range, the belt tension clutch 11 is automatically disengaged via the operating mechanism 15 as the reaping pretreatment device A rises.

The second reaping device 9 can be switched to a predetermined cutting posture via the link mechanism 21 when the storage posture is switched to the use posture. Further, the belt transmission device 12 is always maintained in a tensioned state via a spring 23 fitted externally to the rod 22.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
