Description

[Detailed description of the invention] The present invention provides a clamping vertical conveyance device behind the pulling device to convey the cut husk culms toward the starting end of the feed chain of the threshing device, and the husks conveyed by this conveyance device. The present invention relates to an improvement of the combine harvester, wherein the culm is delivered to the feed chain in a sideways posture, and the conveying device is configured to be vertically swingable with the rear end side as a fulcrum.

As mentioned above, when handling depth is performed by vertically swinging the starting end of the gripping and conveying device, the amount of swinging of the gripping and conveying device must be made considerably large in order to make the amount of change in handling depth sufficiently large. If the swinging space of the clamping and conveying device is large in this way, the threshing device and the pulling device cannot be placed close to each other.
This was a problem when trying to shorten the length of the aircraft front and rear.

The present invention was made keeping in mind the above actual situation,
By rationally improving the conveying structure with a button at the end of the conveying device,
In an attempt to solve the above-mentioned problems, the present invention aims to provide an apparatus in which the posture of the husks supplied to the threshing device is arranged in an orderly manner, which facilitates efficient threshing processing.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The exemplified combine harvester is configured by connecting and equipping a reaping processing section to the front part of the machine on which a threshing device 2 is mounted on a crawler traveling device 1. , the planted culm is pulled up by a pair of left and right pulling devices 3, 3, and the bottom end of the plant is harvested by the reaping device 4, and then the cut culm in an upright position is transported to the bottom of the plant. The threshing device 2 is clamped and conveyed by the device 5, and the husk tip is conveyed by the auxiliary conveyance section 3a, which is constituted by the upper extension of the one of the above-mentioned lifting devices 3. The auxiliary conveyance section 3a is conveyed toward the starting end of the feed chain 6, which is installed on the lateral side facing the longitudinal direction of the machine, and at the conveyance terminal end.
As the conveyance action is released, the tip of the shell culm is laid down and changed to a sideways posture, and the stem of the shell culm in this sideways posture is delivered to the feed chain 6, and the tip of the shell culm is transferred to the guide plate. It is configured to be guided into the threshing device 2 while being placed on γ.

The stock conveying device, that is, the clamping vertical conveying device 5, is configured to be able to swing up and down with its rear end as a fulcrum P, and by this vertical swing, the clamping position for the cut husk in the upright position can be adjusted. The handle depth is adjusted by changing the length in the culm length direction.

In the combine harvester having the above configuration, the present invention is characterized in that the culm delivery point from the stock transfer device 5 to the feed chain 6 is configured as described below.

That is, the stock transfer device 5 includes a chain 5 with protrusions.
A is wound so that it has a first winding portion facing rearward and a second winding portion following this portion toward the inside of the body, and a first gripping rail is mounted opposite to the first winding portion. 5b, and a second clamping rail 8 facing the second winding part.
The stock transfer device 5 has a first path section A along the first winding section, and a first path section A along the second winding section. a second path portion A configured, and both path portions A
The starting end of the above-mentioned Fitch 1.2 Aene 6 faces the bent part of A.

Further, as shown in FIG. 3, the second clamping rail 8 has a base portion 8a connected to the machine frame portion, and a tip portion 8b.
It is constructed so as to be movable in the direction of the rod length, and the relative position of both 8a and 8b can be fixed by fastening bolts 9.

In addition, 10 in the figure is a weak clamping rod arranged opposite to the starting end of the feed chain 6.

According to the above configuration, at the culm delivery point from the stock transport device 5 to the feed chain 6, the culm is transported as described below.

That is, the culm transported to the terminal end of the first path portion A□ is placed on the upper part of the feed chain 6 with the part closer to the plant base than the clamping position of the conveying device 5, and this placement is performed as follows. In this state, after the shell culm is conveyed along the second path section A, the clamping is released and it is delivered to the feed chain 6.

Therefore, while the grain culms are being conveyed along the second path portion A2, they are moved away from the feed chain 6 toward the ears, and thus the length of the second clamping rod 8 increases. By changing and adjusting the path length of the second path portion A2, the culm delivery position to the feed chain 6 can be changed in the culm length direction, so-called handling depth adjustment.

In summary, the present invention is directed to a combine harvester having the officially registered structure. A second inclined path portion is formed so as to gradually approach the threshing device side, and the starting end of the feed chain is formed at the bending portion of both path portions, and the feed chain is held oppositely to the second path portion. A rail is provided, and the clamping rail is configured to be freely changeable and fixed in position along the shell culm conveying direction of the second route, and the length of the clamping route of the second route is configured to be freely changeable and adjustable. do.

In other words, since the handling depth can also be adjusted by changing and adjusting the length of the clamping path in the second path portion, a sufficiently large change in the handling depth is possible even if the amount of vertical swing of the conveying device itself is reduced. Furthermore, the length of the clamping path in the second path portion can be changed within an extremely small space, which is extremely effective in making the aircraft more compact.

Furthermore, according to the present invention, the lifted and cut culm is transported from the pulling device to the threshing device using only one vertical conveying device, which can greatly contribute to further downsizing of the machine. However, the number of times the harvested culms are inherited is also small.
Moreover, the amount of vertical swing at the starting end of this vertical conveying device is much smaller than that of the conventional one, which means that the cutting husk coming from the lifting device is inherited at this starting end. The advantages of having fewer disadvantages of unexpectedly disturbing the posture of the husks work synergistically to produce a unique effect in which there is less risk of holes in the posture of the reaped husks that are lifted and conveyed to the threshing device in one go. As a result, the threshing device can be supplied with cut husks in an orderly manner, which has the advantage of facilitating efficient threshing work.

In addition, the second path portion of the vertical conveyance device is formed into an inclined path that is successively closer to the threshing device side as it gets further away from the feed chain toward the ear tip side in plan view, and the Because the two clamping rails are arranged, the transfer of the cut husk from the end of the vertical conveyance device to the start of the feed chain is an extremely simple structure that does not require any other special auxiliary means, and is smooth. This can be done smoothly, and since the configuration makes effective use of the clamping and conveying device, it is possible to make an extremely simple modification by simply extending, contracting or sliding a part of the clamping rod, which is extremely practical in terms of practical use. Are better.
