Description

[Detailed description of the invention] The present invention relates to a stem culm clamping and conveying device that is attached to a threshing device equipped with a combine harvester and is used to pinch and convey stem culms to be threshed. The purpose is to improve the clamping structure at the starting end of the conveyance so that it can be received well and conveyed appropriately.

Such a stem culm holding and conveying device is movable in the far and near direction of the endless band, facing a portion of the endless band with protrusions for holding and conveying the stem culm, excluding the conveyance starting end, and elastically biased against the endless band. In addition to providing a clamping rail, an auxiliary clamping rail for receiving the stem culm is also provided opposite the starting end of the endless belt conveyance.

In providing this auxiliary holding rail, conventionally, the endless band is supported so as to be movable parallel to the holding rail in the far and near direction, and the endless band is elastically attached with a force weaker than that of the holding rail. However, in this case, the following problem occurred.

In other words, if the stem culm is held between the auxiliary holding rails that move parallel to the far and near directions of the endless belt, there will be no particular problem when the stem culm is fed in one after another, but if the stem culm is fed in a continuous state, It has sometimes been difficult to properly hold the smallest of the stem culms, making it difficult to carry them as desired.

In other words, the final group of stems and culms sent in a continuous state,
In other words, those on the upper side of the conveying direction tend to move unexpectedly to the upper side of the conveying force because they do not have a trailing stem culm. In this case, it is difficult to hold the stem culm while preventing it from moving on the upper side in the direction of conveyance, and for this reason, it may be difficult to carry out the desired conveyance well, and the posture of the stem culm is disturbed, resulting in clogging. There was a risk of causing transportation troubles such as

The present invention was made keeping in mind the above actual situation,
An auxiliary clamping rail provided opposite to the portion of the endless belt with protrusions for transporting stem culms, excluding the transport start end, is a swinging arm that is pivotably supported on the clamping rail so as to be able to swing around the horizontal axis. The lower end in the stem culm conveyance direction is pivotally connected to the free end, and the intermediate part in the stem culm conveyance direction is movable in the endless belt distance direction in a state where it can swing in the endless belt distance direction. It is characterized in that the endless band is supported by the clamping rails and is elastically biased with a smaller biasing force than the clamping rails.

In other words, the auxiliary clamping rail, which can swing in the far and near direction of the endless belt using the lower end of the stem culm conveyance direction as a fulcrum, is capable of swinging in the far and near directions of the endless belt. The upper side of the group of stem culms in the conveyance direction changes to an inclined position closer to the side of the endless band, and the stem culms are held between them. It is possible to reliably hold the stem culm on the upper side in the conveyance direction while preventing the object from moving toward the upper side in the conveyance direction.

In addition, this auxiliary support rail is provided with an arm that is swingably connected to the clamping rail, the fulcrum of which in the stem culm conveyance direction is located opposite to the portion excluding the starting end of the endless band. Because it can move up and down, compared to, for example, one that is directly pivoted without using an arm, the final part of the stem culm group that is continuously fed to the end of this auxiliary clamping rail, even if it has a small volume, can be moved up and down. Even if this happens, the terminal end of the auxiliary clamping rail will also move downwards, making it possible to successfully solve the problem of the final stem culm falling off or becoming misaligned, resulting in a blockage.

As a result, it becomes possible to properly receive and convey the final group of stems and culms, which are continuously fed in, while properly holding them, and this has a great practical advantage. I finally got the device.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figure 1 shows the side of the combine harvester, and the front part of the machine is equipped with a device 1 for raising multiple stem culms planted in the field into an upright position, a reaping device 2 for cutting the base of the culm after being pulled up, and a reaping device 2 for cutting the base of the culm. An auxiliary transport device 3 for merging the culms, transporting the merging culms backward, and
A reaping processing unit 5 is provided, which includes a rear conveyance device 4, etc., which turns the stem culm into a sideways posture at the end of the conveyance, and a stalk culm holding and conveying device 6 attached to the side and side portions is installed at the rear of the machine. A threshing device 7 that handles and threshes grains while holding and transporting them is provided, and a crawler traveling device 8 is installed below the threshing device 7.

As the machine progresses, the culms planted in the field are pulled up and harvested, and the harvested culms are successively threshed after being automatically and continuously carried out.

The reaping pre-processing section 5 is supported by an elevating frame 9 which also serves as a transmission case and is operable to vertically swing around a fulcrum P at the rear end, and is lowered to near the ground during reaping work. At other times it is raised.

The rear conveyance device 4 is configured to be able to be vertically swung and adjusted around a fulcrum Q at the end of the conveyance.

Through this swing adjustment, the conveying device 4 changes the stem culm support position at the conveyance start end toward the culm body, and changes the stem culm support position at the conveyance end to the stem culm holding and conveying device 6 at the conveyance end. is changed in the direction of the culm, and as a result, the handling depth is adjusted by changing and adjusting the amount of insertion of the tip of the stalk into the threshing processing device 7.

The stem culm holding and conveying device 6 will be explained with reference to FIGS. 2 and 3, A and A.

That is, a chain 10 is provided in which a stem culm locking projection lea... is formed, a clamping rail 11 is provided opposite the chain 10 except for the transport start end, and a clamping rail 11 is provided opposite the chain 10 except for the transport start end. An auxiliary clamping rail 12 is provided opposite the section.

The clamping rail 11 is divided into a plurality of parts along the stem culm transport direction, and supports each of the rail members 11a, which are pivotably connected in a bendable manner, movably in the direction of the chain. Alligator is elastically biased.

The auxiliary clamping rail 12 has its lower arm end in the stem culm conveyance direction pivotally connected to the free end of a swinging arm 13 that is pivotably supported around the horizontal axis X1 of the clamping rail 11. At the same time, the intermediate portion of the rod 15 in the stem culm conveyance direction is pivotally connected to the lower end of the rod 15, which is supported through the rotating member 14 which is rotatably supported on the clamping rail 11 so as to be rotatable about the horizontal axis X2. The stem culm is supported so as to be movable in the distance direction with respect to the chain 10 in a state where it can swing in the distance direction with respect to the chain 10 using the lower arm end in the transportation direction as a fulcrum, and the rod 15 is attached downward. The chain is elastically biased by a biasing spring 16 with a biasing force smaller than that of the clamping rail 11.

When the stem culms are continuously fed in as shown in FIG. As shown in the opening in FIG. 3, when the stem culm that is being fed in a continuous state breaks, the stem culm is clamped before changing to an inclined position closer to the chain 10 as the upper side in the conveyance direction approaches.

In the figure, reference numeral 17 denotes a pin for abutting and regulating the downward swing limit of the swing arm 13, and is configured to be removably attached to the clamping rail 11.

Then, if this pin 17 is removed and the auxiliary rail 12 is swung upward as shown in FIG. The starting end of 10 can be opened, making it convenient to use when cutting corners.
