Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, the planted grain culm is raised on the uncut side of the grain culm raising device of the cutting pretreatment section mounted on the front part of the traveling machine body at a position in front of the grain culm raising device. After combing along the raising direction of the cutting device, a composting device is provided to forcibly guide the picked grain culm rearward and outward on the side of the uncut mower in the pre-cutting section. Numbine's forced weeding device.

[0002]

[Prior art]

 Conventionally, in this type of combine forced weeding device, a compulsory weeding device that combs uncut grass grain culms is formed on an endless swivel belt inside the case in the combing path. There is known a structure in which a locking claw for use stands up, and the claw locks the uncut culm to separate it from the culm to be mowed, and the lateral outside of the cutting pretreatment section or the traveling machine body. I tried to push the uncut culm to the one.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, the uncut mower grain culms easily rub against the upper and lower edges along the front and back of the case in which the endless swivel belt is installed. There was a risk that the culm would be cut and the tip part would fall off. The present invention has been made in view of the above circumstances, and provides a combined weeding device for combine harvesters that can eliminate the problem that the rice culm is cut off due to friction between the culm and the case of the forced weeding device. With the goal.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the combine forced weeding device of the present invention has the above-mentioned structure, and in the structure described above, the uncut grass grain culm is controlled by restricting the stock of the uncut rice grain culm. A rod-shaped restricting member that prevents the forced weeding device from falling down is attached to the front end of the rod-shaped restricting member near the front end of the forced weeding device and extends rearward. The operation and effect of this characteristic configuration are as follows.

[0005]

[Action]

 In other words, the bar-shaped restricting member prevents the forcing plant of uncut grass culm from falling down by the forced weeding device, so that the tips of the grain stalks are also combed by the forced weeding device. Since the grain is not transported while leaning against the forced weeding device while being transported, it is possible to prevent the culm from rubbing against the case of the forced weeding device.

[0006]

[Effect of device]

 Therefore, rubbing between the forced weeding device and the uncut mower grain culm is suppressed, and the rubbing prevents the uncut mower grain culm sown by the forced weeding device from being cut, The problem that the tip of the grain culm was unreasonably dropped from my stock has been resolved.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the front part of the combine. In this combine, the threshing device 3, the control unit 4, the driving unit, etc. are mounted on the traveling machine body 2 supported by the pair of left and right chloror traveling machines 1 and 1, and at the front part of the traveling machine body 2, The cutting pretreatment unit 6 is mounted so as to be able to move up and down around the axis P.

As shown in FIGS. 1 to 3, a fixed divider 7 for weeding the planted culms, a grain culm raising device 8 for raising the cultivated grain culms, and a reaper are set in the pre-mowing processing unit 6. It comprises a harvesting device 9 for cutting and cutting the root of the grain culm, and a vertical transport device 11 for transporting the harvested grain culm to the threshing feed chain 10 of the threshing device 3. More specifically, the cutting machine pretreatment section 6 is supported on the traveling machine body 2 so as to be movable up and down around the horizontal axis P, and is extended forward to the support frame 12 which is also used as a transmission case for the cutting pretreatment section 6. The fixed divider 7 is fixed to the tip end of the divider supporting rod 13 connected in the above state, and the grain culm is raised by the divider supporting rod 13 and the raising device transmission case 14 that is erected from the support frame 12. The device 8 is fixed. Then, among the plurality of grain culm raising devices 8 arranged side by side on the left and right, the grain culm raising device 8 located closest to the uncut land is supported via the bracket 15 to the divider support rod 13 that supports the grain culm raising devices 8 at the bottom. 1 Forcibly weeding device 16 is supported on the upper end of the weeding device drive transmission case 17 which extends further upward from the raising device transmission case 14 in a state of being branched laterally and rearward. The second forced weeding device 18 is attached and supported. In the first forced weeding device 16, sprocket wheels 16b and 16c as rotating bodies are rotatably mounted on both upper and lower sides of an outer case 16a connected to the bracket 15, and a chain 16d is extended across the sprocket wheels 16b and 16c. The hooks 16e are engaged around the chain 16d at appropriate intervals, and the hooks 16e project from the outer case 16a so that the hooks 16e can be locked in the upward movement path of the chain 16d. The guide rail 16f is erected in this state, and the claw 16e is laid down in the downward transfer path in a state of being stored in the outer case 16a. The second forced weeding device 18 has sprocket 18b, 18c as a rotating body, which is internally rotatably mounted on both front and rear sides of an outer case 18a connected to the transmission case 17 for driving the weeding device. A chain 18d is wound around 18b and 18c, and a hook 18e for locking a grain culm is pivotally attached to the chain 18d at appropriate intervals, and the claw 18e locks the grain culm in a backward transfer path of the chain 18d. The guide rail 18f stands up so as to project from the outer case 18a so that the pawl 18e falls down in the state of being stored in the outer case 18a in the forward transfer path. Further, the upper end portion of the first forced weeding device 16 and the front end portion of the second forced weeding device 18 are arranged so as to overlap in a side view, and the second forced weeding device 18 is the first. 1 It is arranged so that it is located outside the uncut grass from the forced weeding device 16. Further, the sprocket 16b of the first forced weeding device 16 and the sprocket 18b of the second forced weeding device 18 are integrally connected to a common rotary support shaft 19, and the transmission case 17 for driving the weeding device is provided. The rear transmission sprocket 18c is driven by the internal transmission shaft 20, and the front transmission sprocket 18b is rotated by the drive shaft 20 via the chain 18d. When the upper sprocket 16b is rotationally driven, the chain 16d is also rotationally driven. Here, the first forced weeding device 16 and the second forced weeding device 18 constitute a forced weeding device A.

As shown in FIG. 2, the divider support rod 13 is formed of a round pipe member, and the mounting portion of the bracket 15 on the divider support rod 13 is formed by bending a little in a forward-downward-inclined posture. Reference numeral 15 is externally fitted to the divider support rod 13 so as to be rotatable around its central axis Q in a slightly downwardly inclined posture. On the other hand, in the weeding device drive transmission case 17 branched from the raising device transmission case 14, the front-rear transmission case 17a at the position where the branch transmission shaft extends in the front-rear direction is connected to the raising device transmission case 14. The lateral branch transmission case 17b is rotatably supported around the central axis Q. As a result, the forced weeding device A 1 is supported rotatably around the central axis Q as a whole. In order to rotate the forced weeding device A about the central axis Q and to stop it in a predetermined posture, the support bracket 21 connected to the raising device transmission case 14 is connected to the central axis Q with the central axis Q. A waist-breaking link mechanism 22 is pivotally mounted so as to be rotatable about parallel axes R, and a tip portion of the waist-breaking link mechanism 22 is pivotally mounted to the second forced weeding device 18. As shown in FIG. 4, the waist bending link mechanism 22 includes a pair of arm members 22a and 22b that can be bent in the middle and a rotating arm 24 that can be driven to rotate about the axis R by an electric motor 23. It is configured. That is, the pinion gear 26 of the front-rear output shaft 25, which is interlockingly connected to the electric motor 23 fixedly installed on the support bracket 21 through a reduction mechanism, is attached to the rotating arm 24 so as to be rotatable around the axis R. It is meshed with a large-diameter rack gear 27 that is integrally connected. The electric motor 23 moves the forced weeding device A to the central axis Q so that the electric motor 23 is tilted to the lateral side corresponding to the adjustment position of the adjustment dial by artificially turning the adjustment dial provided in the control section 4. It rotates in steps around it. In addition, the tension spring 28 is provided over the arm member 22b pivotally attached to the second forced weeding device 18 and the arm member 22a pivotally attached to the rotating arm 24, and the pulling spring in the arm member 22a is provided. The stopper member 28 is provided with a stopper 29 for restricting contact with the arm member 22b so that both arm members 22a and 22b are not bent outward. The waist breaking link mechanism 22 allows the forced weeding device A to easily retract from the obstacle when the forced weeding device A collides with the obstacle from the outside, for example.

With the above configuration, the posture of the forced weeding device A can be artificially set to the side of the machine by operating the adjustment dial, and the claws of the forced weeding device A for the uncut corn can be set appropriately. The heights of the 16e and 18e to be locked to the ground can be changed. Moreover, the grain culm raising direction of the first strong weeding device 6 is set to substantially follow the raising direction of the grain culm raising device 8 in a side view. Furthermore, as shown in FIG. 5, the fixed divider 7 is arranged in a rearward-spreading manner so that the fixed divider 7 does not interfere with the pawl 16e to be raised at the claw standing portion below the first forced weeding device 16. The pair of rods 7a and 7b provided is provided in a V shape in plan view, and the outer rod 7b is shorter than the inner rod 7a.

Further, as shown in FIGS. 1 to 5, a rod-shaped regulating member 29 is fixedly connected to the lower portion of the outer surface of the outer case 16 a of the first forced weeding device 16. The rod-shaped regulating member 29 is rearwardly oriented along the rear transfer path of the claw 18e of the second forced weeding device 18 so that its rear end is located below the rear end of the second forced weeding device 18. It has been extended. Therefore, the rod-shaped restricting member 29 abuts the root portion of the uncut mower grain culm, and the forced weeding device A regulates the uncut mower grain culm from falling. Further, a pipe member is formed by bending on the outer side surface of the outer case 16a of the first strong weeding device 16 and the upper side portion of the outer side of the outer case 18a of the second forced weeding device 18. A guard member 30 for preventing wear of the grain culm is fixed. Even if the tip cutting edge of the uncut culm may contact the second forced weeding device 18, the curved surface of the guard member 30 serves as the contact point of the grain cutting tip. As compared with the case where the outer case 18a is in contact with the corner of the upper side of the outer surface, abrasion of the grain culm due to the contact can be suppressed.

The present invention may be implemented as follows. (B) Instead of disposing a plurality of endless belts for transportation on the front and rear of the forced weeding device, configure a series of endless swivel belts. (B) Attach the tip of the rod-shaped regulating member to the divider support rod instead of the forced weeding device.

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.
