Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an internal device for dividing a grain culm reaper such as a binder or a combine harvester.

(Prior art and problems) A grain culm reaper is equipped with a grain culm pulling device having tines located in front of the cutting blade, and the grain culm is harvested while being pulled up by the pulling device. It's summery. In addition, when harvesting grain culms that have fallen down, the grain culms are generally separated using a guide rod (narrow guide) and pulled up using a lifting device, but the grain culms are intertwined with each other and lie down in multiple directions. A good weeding action could not be expected with the grain culms that were present, and the grain culms were cut or pulled up during shearing with tines, making reaping work difficult.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and is a grain culm reaping device equipped with a grain culm pulling device at the front of the traveling machine in the direction of movement of the machine. In the machine, the dividing draft inner body is placed oppositely along the upper surface of the case of the above-mentioned lifting device with an appropriate interval and the lower end of the slope is covered by the divider of the reaping part, and the dividing draft inner body is raised accordingly. The device is pivotally supported to be swingable in the vertical direction and slidably in the longitudinal direction of the device using the side near the end of the device as a fulcrum, and is connected via a crank mechanism to a drive section led out from the side near the start end of the device. The lower end side of the inner body of the dividing draft is interlocked and connected, and in response to the operation of the pulling device, the inclined lower end of the inner body of the dividing draft swings greatly in the vertical direction inside the divider on the side of the stock of the standing grain culm. However, by configuring the swing width to become smaller as it goes toward the upper end of the inner body of the dividing draft, the inner body of the dividing draft can lift up the base of the grain culm stock, which can then be taken over by the lifting device. In particular, for lodging grain culms that are entangled, grain culms can be harvested reliably without cutting the grain culms by performing an effective action of loosening the tangles of the grain culms. It is an object of the present invention to provide an internal device for a reaper.

(Embodiment) To explain the configuration of the present invention with reference to an embodiment shown in the drawings, reference numeral 1 is a grain culm lifting device manufactured by Bandai A, and this lifting device 1 is installed on a traveling aircraft 3 equipped with an engine 2. It is installed at the front in the direction of travel in a manner that is low in the front and high in the rear.The starting end (slanted lower end) of the structure is raised by the stay 4, and the ending part is connected to the transmission pipe 5.
are respectively supported on the body frame 6 by.
Reference numeral 7 denotes a chain covered by a case 8, which is suspended between a driving sprocket 9 and a driven sprocket 10, and the chain 7 has lifting pawls (tines) 11 arranged at regular intervals around the entire circumference. It is pivoted freely. As shown in FIG. 2, the tines 11 stand up outside the case 8 just before the lifting action begins, and after the lifting action ends, they fall down and sink into the case 8.

Reference numeral 12 denotes a dividing draft inner body which is disposed oppositely at an appropriate distance along the upper surface of the case 8 of the lifting device 1, and one end side of the dividing draft inner body 12 is connected to a bracket 13 near the terminal end of the lifting device 1. , fulcrum pin 14 and long hole 15
is pivotally supported to be vertically swingable and slidable in the longitudinal direction of the lifting device 1 within the range of the elongated hole 15, and the other end side is a drive unit led out from the starting end side of the lifting device 1. A is interlocked with the crank mechanism b via a crank mechanism b. The interlocking configuration is as follows. That is, the gear case 16 is located directly above the driven sprocket 10 of the lifting device 1 and is mounted on the upper surface of the case 8.
is fixed, and one end of the crank 18 is fixed to the protruding end of the shaft 17 protruding to one side of the gear case 16, while a pin 19a is attached to the lower end side of the dividing draft inner body 12.
The rod 19 is pivotally supported via the rod 19, and the free ends of the rod 19 and the crank 18 are pivotally connected to each other,
A fulcrum guide 21 in which the middle part of the rod 19 is rotatably attached to the gear case 16 via a shaft 20
It is slidably inserted into the body. The crank 18 is linked to a driven sprocket 10 of the pulling device 1 through a gear group (not shown) in the gear case 16, and when the pulling device 1 is operated, the crank 18 moves in the direction of the arrow in FIG. It is designed to rotate.

In the figure, 22 is a cutting blade, 23 is a binding device, and 24 is a grain culm conveyance guide. By the way, the above draft inner body 12
As shown in the figure, the lower end of the slope is protected by being covered with a divider 25, so that it does not get caught on the grain culm or come into direct contact with obstacles.

In the configuration as described above, when the various parts of the machine are started to start reaping work, the crank 18 rotates in the direction of the arrow in FIG. 1 in conjunction with the pulling device 1, and the rod 19 pivotally connected to the crank 18 rotates. performs rocking motion and sliding motion (with respect to the fulcrum guide 21) via the fulcrum guide 21, but due to the above-mentioned crank motion, the other end of the rod 19, that is, the pivoting portion between the rod 19 and the dividing draft inner body 12, moves in an elliptical motion. As a result, the inclined lower end of the dividing draft inner body 12 becomes the divider 25.
It oscillates vertically in an elliptical trajectory C. This swinging action is configured such that the inclined lower end side of the dividing draft inner body 12 swings greatly in the vertical direction, so that the dividing draft draft inner body 12 moves against the grain culm stock base in the field. Prior to the pulling action, a continuous up-and-down rocking motion provides a plowing and weeding action, which allows the plant base to be transferred to the tines of the pulling device 1 in a lifted state. Therefore, the dividing draft inner body 12 performs an extremely effective action on grain culms that are lodging and entangled, by loosening the tangles of the lodging materials and raising them up. Even if there is a problem, the grain culm can be reaped reliably without being cut or pulled up due to the forced lifting action of the lifting device 1.

In addition, since the vertical swing width of the dividing draft inner body 12 becomes smaller toward the upper end, there is no adverse effect on the lifting action of the lifting device 1 itself. By the way, most of the entanglement of grain culms in the field is caused by the grain culms in adjacent rows falling toward each other and the left and right grain culms intersecting each other (grain culms falling in the same direction). culms are less likely to intertwine with each other), and
The culm side of the standing grain culm has the thickest culm diameter, is sturdy, and is difficult to break.Moreover, because the grain culms in adjacent rows lean against each other at the culm part, the grain culm breaks at the culm and completely collapses from the culm. In reality, this is almost never the case, and therefore, the intertwining of grain culms appears on the upper side in the direction of the culm, and it is extremely rare for the grain culms to intertwine with each other on the upper side of the culm. On the other hand, since the part on which the inclined lower end side of the dividing draft inner body 12 acts is the stock base of the standing grain culm, even if the inclined lower end side of the dividing draft inner body 12 swings greatly in the vertical direction, the grain culm is not affected during actual work. There is almost no risk of it being cut.

In addition, since the power of the dividing draft inner body 12 is taken out directly from the pulling device 1, a special power transmission mechanism is not required, and the interlocking structure can be made simple and compact.

As described above, the present invention provides a grain culm reaper equipped with a grain culm pulling device at the front of the traveling machine in the direction of movement of the machine, in which the pulling device is spaced at appropriate intervals along the upper surface of the case, and has a sloping lower end. The inner bodies of the dividing drafts are placed opposite each other while covered by the divider of the reaping section, and the inner bodies of the dividing drafts are pulled up so that they can freely swing vertically using the side near the end of the pulling device as a fulcrum, and the longitudinal direction of the pulling device. In addition to being pivotally supported so as to be able to slide freely in the direction, the lower end side of the inner body of the dividing draft is interlocked and connected via a crank mechanism to a drive unit led out from the side closer to the starting end of the pulling device, and responds to the operation of the pulling device. The inclined lower end of the inner body of the dividing draft swings greatly in the vertical direction within the divider on the stock base side of the standing grain culm, and the width of the swing becomes smaller as it goes toward the upper end of the inner body of the dividing draft. Because of this structure, the inner body of the dividing draft lifts the base of the grain culm, allowing the lifting device to take over, and especially for tangled and lodging grain culms, it is possible to loosen the tangles of the grain culms. Because of this, it is possible to reliably harvest even in a lodging grain culm without cutting or pulling up the grain culm, and the divider protects the lower end of the inner body of the dividing draft. Since it can act as a protective cover, it can prevent the inner body of the dividing draft from getting caught on the grain culm or being damaged by direct contact with obstacles, thereby reducing the grain culm conditions in the field. Regardless of the situation, reaping work can always be carried out smoothly, and there is no need to separately install a particularly complicated mechanism for transmitting power to the internal body of the divider, and it can be easily installed on conventional products. There is an effect.
