Description

[Detailed description of the invention] The present invention is equipped with a clipper-type cutting blade that moves a movable cutting blade horizontally along the upper part of the fixed receiving blade, and the cutting stem culm is moved horizontally along the cutting blade. This invention relates to a reaper equipped with a stem culm conveying device that feeds the stems and then sends them rearward.

The above-mentioned reaping machine has an inexpensive and simple structure that makes effective use of clipper-type cutting blades, and is capable of horizontally feeding the reaped stem culm, but on the other hand, it has the following disadvantages.

In other words, at the part of the cutting blade that corresponds to the part of the cutting blade where the stem culm is rear-fed, the straw waste and mud separated from the stem culm are pressed against the base of the stem culm, which is sequentially fed backward, so that it is fixed. There was a tendency for the blade to get in between the receiving blade and the movable cutting blade, and as a result, the fixed receiving blade and the movable cutting blade could not be brought into close contact, resulting in the inconvenience that the cutting performance of the cutting blade deteriorated. . In addition, in the area corresponding to the part of the cutting blade where the stem culm is fed sideways, straw waste and mud separated from the stem culm are collected between the V-shaped cutting edge of the movable cutting blade and the V-shaped cutting edge of the fixed receiving blade. The gas is emitted through the edges, and the above-mentioned disadvantages do not occur.

The present invention was developed in view of the above-mentioned circumstances, and is a simple modification that effectively utilizes a plurality of knife clips provided in the width direction to press the movable cutting blade against the fixed receiving blade. This is an attempt to resolve the inconvenience.

Embodiments of the present invention will be described in detail below based on illustrative drawings.

As shown in FIGS. 1 and 2, a crawler traveling device 1, a device 3 for threshing while holding and conveying the root of the stem culm rearward with a feed chain 2 on the left side,
And, in the front part of this machine equipped with the driver's seat 4, etc., located on the front right side of the threshing device 3, there are a pair of left and right culms that are introduced into the pair of left and right culm introduction paths A, A. A pair of left and right auxiliary conveyance devices 6, 6 that lock and transfer the tips of the raised stalk culms to locations corresponding to both paths A, A, and a stock base of the raised stalk culms. A pair of left and right clipper-type cutting blades 7 that cut the cutting stem culm, and a pair of left and right blades that feed the cut stem culm horizontally to a location corresponding to between both paths A and A, with the base end of the stem being received and supported by the cutting blade 7, and then sent rearward. stem culm conveying devices 8, 8, and a stock clamping conveying device 9 that conveys the stem culms from both the conveying devices 8, 8 backward and changes the posture to fall sideways at the end of the conveyance and transfers them to the threshing device 3; A reaping processing unit equipped with a rear conveyance device consisting of a tip-holding conveyance device 10, etc. is provided, and as the field progresses, the stem culms planted in the field are pulled up and harvested, and the harvested stem culms are successively threshed. It is configured to perform tasks automatically and continuously.

During normal reaping operations, the combine harvester configured as described above performs round mowing or reciprocating mowing with the uncut stem culm positioned on the left side of the machine body. As shown in FIGS. 1 and 2, a work light 11 is installed above the starting end of the feed chain 2, at the entrance of the threshing device 3, at the rear conveyance section, and to the left of the pulling devices 5 and 6. It is installed in such a way that it illuminates the uncut stem culms located laterally, so that it can be used even at night.

As shown in FIGS. 3 and 4, the clipper-type cutting blade 7 is constructed by attaching a fixed receiver blade 7 to the cutting blade stand 12.
three knife clips 13, 1 in the width direction that fix the blade a and press the movable cutting blade 7b towards the fixed receiving blade 7a;
3 and 13a are positioned at both lateral ends of the cutting blade 7 and at a portion of the cutting blade 7 corresponding to the portion of the cutting blade 7 where the stem culm is sent backward, and the respective rear ends are bolted to the cutting blade stand 12. A pair of front and rear guide surfaces S ₁ , S are provided in a fixed state and are provided on the inner surface of each knife clip 13 . ₂ , and further includes a movable cutting blade drive crank arm 1.
5 is provided so as to act on a locked piece 16 fixed to the knife bar 14, so that the movable cutting blade 7b is laterally reciprocated along the upper part of the fixed receiving blade 7a. Also, knife clip 13...
Among them, the movable cutting blade 7b has a cutting blade 13a located at a position corresponding to the part where the stem culm is transversely fed, and its front edge in a plan view
The knife clip 13a is installed so that it is positioned toward the front of the tip of the blade, and the base of the stem culm, which is moved backwards, is caught and supported by the knife clip 13a, thereby removing straw waste and dirt that have separated from the stem culm. The movable cutting blade 7a is configured to prevent the movable cutting blade 7b from entering between the fixed receiving blade 7a and the movable cutting blade 7b, which are pressed against the base of the stem culm being sent backward, and to always maintain good cutting performance of the cutting blade 7. be.

In addition, in the example, the case where the reaped stem culms from the two routes A and A are combined by cross-feeding and sent later is illustrated, but it is also possible to send the cut stem culms from only one route A later. , the merits are applicable.

Further, in carrying out the present invention, the movable cutting blade 7b in the cutting blade 7 has a horizontal reciprocating drive structure and the knife clip 13.
The number of ... can be changed in various ways.

Further, the present invention is applicable to various types of reaping machines such as binders.

In summary, the present invention provides the above-mentioned reaper,
One of the plurality of knife clips 13 in the width direction that presses the movable cutting blade 7b against the fixed receiving blade 7a is connected to one 13a corresponding to the portion of the cutting blade 7 where the stem culm is fed backward. The movable cutting blade 7b is characterized in that it is located at a location where the movable cutting blade 7b is located, and its front edge is located further forward than the inner part of the V-shaped cutting edge of the movable cutting blade 7b in plan view.

In other words, the knife clip 13a, which is located at a portion of the cutting blade 7 corresponding to the part where the stem culm is sent backward, is configured to receive and support the base of the stem culm that is sent backward, so that it does not detach from the stem culm. This eliminates the above-mentioned inconvenience in which straw waste and mud enter between the fixed receiving blade 7a and the movable cutting blade 7b, which are pressed against the base of the stem culm, which is sequentially fed back, and the cutting performance of the cutting blade is always maintained at a good level. Moreover, according to the present invention, as described above, one of the plurality of knife clips 13, 13a in the width direction that presses the movable cutting blade 7b against the fixed receiving blade 7a. Since the desired purpose can be achieved by effectively utilizing the stem 13a, the desired purpose can be achieved at a lower cost and more easily than by adopting other means, such as installing a special stem culm stock guide cover. This has great advantages in terms of implementation and production.
