Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm lifting and conveying device in a reaping and threshing machine.

In general, a reaping and threshing machine has at least a culm pulling device, a culm reaping device, and a reaping device for reaping the husk to be planted and supplying it to the threshing device. a head side conveying device for conveying the tip side of the harvested husk and supplying it to the threshing device; and a head side conveying device for conveying the tip side of the harvested husk and supplying it to the threshing device, and a head side conveying device for conveying the stock end side of the harvested husk and feeding it to the bundle handling device of the threshing device. However, in conventional devices, the culm lifting device and the culm tip side conveying device are generally separate mechanisms. In the conventional device, the culm, which has been raised by the pulling device and cut by the reaping device, is conveyed by the conveying device on the tip side and the conveying device on the plant base side, in an extremely short period of time. Since the attitude of the ear must be changed to lie down in the conveying section in the direction, the conveying device on the tip side is composed of a vertical conveying device and a horizontal conveying device.

Therefore, in such conventional devices, the transfer stroke of the culm is long and bends are formed during the transfer process, so the transfer efficiency is generally low and the horsepower loss is large.
It had drawbacks such as a complicated structure and heavy weight.

As a product that eliminates these drawbacks,
A reaping and threshing machine as shown in Japanese Patent No. 8882 has been proposed, but this has the following drawbacks.

In other words, the reaping and threshing machine shown in Japanese Patent Publication No. 4418882 is equipped with a culm pulling device and a culm raising device, which are essential mechanisms for reaping and threshing machines, in order to eliminate the above-mentioned drawbacks of conventional devices. As an alternative to both of these, the system integrates the conveying device on the tip side and raises the planted husk from the front of the reaping device toward the tip side of the culm supply port located in front of the threshing device. It is proposed that an endless lifting body with a lug be installed in tension, and in this case, the following two functions will be performed by a conveying device on the unified lifting end side. It is said that

That is, in the lower part of the first half, the culm is pulled up and subjected to the erecting action by the endless band, and in the upper part of the latter half, the culm is raised and subjected to the erecting action by the endless body, but it remains the same. The intention is to have the action of sending the husk to the culm supply port of the threshing device by the action of the endless lifting body, but it is not possible to use a unified lifting mechanism consisting of such an endless body. For those designed to carry out both of the above operations using only the side conveyance device.

It comes with the following fatal flaws:

In other words, this unified lifting and tip side conveying device has to tilt the culm while conveying the tip side. It is not possible to provide a large inclination angle greater than (around 100°).

This is because if the angle of inclination is too small, the distance after the cutting of the culm is too small, and the culm cannot be tilted during that time.

Therefore, with an endless body whose inclination angle is set small, the lifting angle is inevitably insufficient, and the amount of lifting of the tip relative to the amount of movement of the machine is insufficient, so when mowing on the opposite side, the tip of the tip may lag. This had the fatal disadvantage of causing grain to get caught in between the grains and shedding (making it impossible to cut in the opposite direction).

In a system in which the above two functions are carried out by the unified lifting and tip conveying device, it is impossible to change the posture of the culm while conveying the tip side. If the lifting action is not smooth, and if the lifting action is performed smoothly, that is, if the angle of inclination of the endless body is set to the same angle, the conveyance section will be insufficient and the posture of the culm will not be able to be changed. It had a fatal flaw that would inevitably cause it to collapse, and it was impossible to put it into practical use as it was.

Therefore, the inventor set out to solve the above-mentioned drawbacks of the conventional device and the above-mentioned proposal.

In particular, the raising device and the tip-side conveying device of the reaping and threshing machine are configured as follows, that is, the conveyor has a lug from the front of the reaping device to the tip side of the culm supply port located at the front side of the threshing device. An ear tip conveying device consisting of an endless body and a guide rod or guide plate provided opposite thereto is provided, and a raising device is provided that wraps over the upper part of the front part of the action area of the conveying device to raise the planted culm. A lifting device consisting of an endless lifting member having a lifting lug and a guide rod or a guide plate provided opposite thereto is provided, and the front ends of the tip conveying device and the lifting device are aligned in the front and back direction, and the lugs of both are aligned. I came up with the idea of arranging them facing each other.

According to the reaping and threshing machine constructed in this manner, the lifting device is constituted by a combination of a single endless body having a lifting lug and a guide rod or guide plate disposed opposite thereto. Despite this, he discovered that the scales could be cut by pulling up the two-lined culm smoothly, and this invention
In order to more smoothly convey the husk culm in such a case, the husk culm lifting and conveying device in the reaping and threshing machine configured as described above is constructed as follows.

That is, the gist of the present invention is that the guide portion provided opposite to the lifting lug of the endless lifting body is located above the conveying endless body along one side of the conveying path of the former tip conveying device. Another feature of the present invention is that it is constituted by a ridgeline portion of a tip conveying frame made of a plate-shaped body forming a tip receiving section.

Next, an example will be explained with reference to figures. In the figure, 1
(This is a threshing device mounted on a machine body 3 having four crawler crawlers 2, and the handling barrel (not shown) of this threshing device 1 is
It is arranged so that its @ line direction coincides with the traveling direction of the body 3, and a shell culm supply port 4 is provided at the front side thereof.

Further, the culm supply port 4 is connected to it and a guide rod 6 by a handling bundle transfer chain 5 provided on one side of the machine body 3.
In the reaping and threshing machine of the present invention, the planted husks are harvested by the reaping device 7 disposed at the front lower part of the threshing device 1. In particular, the culm is provided with a lifting device 8 and a tip conveying device 9 as follows.
The culm is pulled up by the above-mentioned ear tip conveying device 9, and while its tip side is being conveyed, the root of the culm is harvested by the reaping device 7. While being conveyed by the culm 10, its posture is changed so that the tip side of the culm is directly supplied to the tip side of the culm supply port 4 by the tip conveying device 9.

First, the ear tip conveying device 9 will be explained. It consists of an endless chain 12 having a conveying lug 11 arranged at an angle of about 45 degrees from the front of the reaping device 7 toward the tip side of the culm supply port 4. , a guide rod 1 installed opposite to this endless chain 12
The endless chain 12 is connected to the body 3 by a horizontal axis (not shown).
The suspension is rotated by sprocket wheels 18, 19, and 20 that are pivotally supported on the tip conveying frame 14, which is integral with the machine frame and is pivotably supported on the machine frame. , and are arranged at regular intervals on the endless chain 12 and have their proximal ends pivotally attached. Due to the action of a guide plate (not shown), the front lower end of the ear tip conveying frame 14 is caused to protrude to the operating position, and then the tip is projected to the operating position until it reaches the upper end. It is kept in good condition.

The guide rod 13 is disposed at a position where the tip of the conveying lug 11 protruding from the operating position can slide thereon, and a conveying path 9a for the tip is formed between the guide rod 13 and the endless chain 12. However, above the endless chain 12 along one side of the conveyance path 9a of the ear tip conveying device 9 according to the present invention, there is a plate-shaped body that constitutes the ear tip conveying frame 14. A tip receiving section 14b is formed which is slightly inclined to the right in the direction of movement of the reaping and threshing machine, and a portion 14a of the ridgeline where the front surface 14c of the tip conveying frame 14 made of a plate-shaped body and the tip receiving section 14b intersect. This constitutes a guide section that is disposed opposite to the lug of the lifting device 8, which will be described next.

That is, next, the raising device 8 will be explained.The raising device 8 wraps the conveying lug 11 above the position where it is projected into the action area of the ear tip conveying device 9, and also wraps its front end into the action area of the ear tip conveying device 9. The lifting device 8 is arranged so as to be aligned with the front end of the machine frame 3a in the longitudinal direction. It has a lifting frame 21 and lifting lugs 26, 26, which are suspended between sprocket wheels 24, 25 which are disposed above and below the lifting frame 21 and are pivotably supported 22, 23. Endless chain 27 and
The lifting lug 26 protruding to the operating position is located at a portion of the ridge line 14
The lifting lug 26 is configured with a part of the tip conveying frame 14, that is, the ridgeline portion 14a, which is disposed at a position opposite the lifting device 8 so as to be able to come into sliding contact with the lifting lug 26. By means similar to the triggering device t,
The front lower end of the lifting frame 21 is made to protrude to the operating position, and the section up to the vicinity of the upper end is maintained in the state in which it is protruded to the operating position. There is.

As described above, the conveying lug 11 of the ear tip conveying device 9,
The lifting lugs 26 of the lifting device 8 are upper parts that project in opposite directions at the operating position.

Parts of the action area are arranged one above the other and are wrapped, and the lifting device 8 has an inclination angle of about 6
5 degrees, and the trajectory of the transport lug 11 and the trajectory of the lifting lug 26 are set so that their frontmost ends pass through the same height position at the same forward position. .

Next, the stock transfer device 10 will be explained. This stock transfer device 10 is also attached to the machine frame portion 3a. A movable frame 32 pivoted 31 to 3a, and sprocket wheels 35, 36 pivoted 33°34 on the movable frame 32.

sprocket wheel 3 pivoted at the fulcrum 31 position;
7 and these sprocket wheels 35°36.37
The suspension consists of a chain 38 that is turned around and a guide frame 39 that is placed opposite to the chain 38, and the stock side of the cut culm is sandwiched between the chain 38 and the guide frame 39. The bundles are transported and supplied in the direction of the handling bundle transfer chain 5.
A pair of star wheels 40 and 41 are disposed at the front end of the vehicle.

That is, one starwheel 40 is provided coaxially with the sprocket wheel 37, while the other starwheel 41 is pivotally supported on the machine frame portion 3a, and the pair of starwheels 40, 41 are mutually disposed. The pair of star wheels 40 and 41 are located at an intermediate position in the width direction directly above the cutting blade device 7, and are driven in the direction of the cutting blade. It is arranged to act on the stump of the cut culm and push it into the front end of the stump transferring device 10.

In FIG. 1, numerals 45 and 46 are dividers disposed at the front ends of the outside of the lifting device 8 and the outside of the tip conveying device 9, and 47 is a driver's seat.

Next, to explain the operation, in the reaping and threshing machine equipped with the lifting and conveying device of the present invention, the pulling device 8 and the ear conveying device 8 have different inclination angles (65° and 40°, respectively).
5°), both of which are partially wrapped in the manner described above, and the latter tip conveying device 9, consisting of a series of endless chains 12 and guide rods 13, is extended to the tip of the pulling device 8, and the lifting lug 26 and the conveying lug 11 of the endless chain 27.12 constituting both are arranged to face each other, and, The lifting path B is located at a position opposite to the lifting frame 21 of the former lifting device 8, and is provided opposite to the lifting lug.
The guide section that constitutes the tip conveying frame 1 is made of a plate-shaped body.
The front surface 14c of 4 and the tip receiving section 1 along the tip conveying path 9a.
4b intersect with each other, the husk lifting and conveying device of this reaping and threshing machine operates as follows.

That is, when two-row cutting is performed using the reaping and threshing machine of this embodiment, the two-row culm A, l;! is planted while maintaining the width α. ,
Due to the action of the dividers 45 and 46 on both sides, a portion where the lifting device 8 and the tip conveying device 9 always overlap each other,
In other words, it is guided to the frontmost end of the lifting and conveying path B.

At this time, if the two culms A and A are lying down, those lying down on the right side of the center of the lifting and transporting path B are caused by the action of the transporting lug 11.

If the item is lying on the left side of the center, raise it with the lug 26.
By the action of , they are each pulled up and drawn to the frontmost end portion of the conveyance path B.

Thus, the two planted culms A, A between the two dividers 45 and 46 move along the lifting conveyance path B as the aircraft 3 moves forward.
The speed of the transport lug 11 and the lifting lug 26 acting on the culms A, A, etc. on the path B is the cosine value (projected speed # ) is made to match the advancing speed of aircraft 3, and the culms A, A...
... is because the angle of inclination is large while the lifting device 8 and the tip conveying device 9 overlap while the machine body 3 is relatively retreated to the rear within the lifting conveyance path B. It is raised only by the action of the raising lug 26 of the upper raising device 8, and is located between the planted shell culms A and A raised lower than the raising device 8, and has the same ground speed (zero speed) as the shell culm A. ), the transport lug 11 that moves rearward relative to the fuselage 3 cannot perform any action on the shell culm A during this wrap section, but Culm A
When it eventually goes out of the area of action of the lifting lug 26, the tip side of the raised culm is in turn moved by the transporting lug 1.
At the beginning, the culms A, A, and A. . In the side conveyance section, the culm A is gradually turned over by the cooperative action with the single plant conveyance device 10, and is changed to a posture in which it can be supplied to the supply port 4. In the culm lifting and conveying device according to the present invention, the guide portion provided opposite to the lifting lug 26 is arranged so that the guide portion is arranged in a direction opposite to the front surface 1 of the ear tip conveying frame 14 made of a plate-like body.
4c and the ridgeline portion 14a formed by the ear tip receiving portion 14b.
Therefore, the tip of the culm pulled up by the pulling device is directly connected to the tip receiving part 14b following the ridge line part 14a, and the tip part of the culm is directly attached to the tip receiving part 14b without changing the grip. The tip is kept leaning against the section 14b, and the tip is fed to the supply port while the tip of the plant is lifted by the plant transfer device 10, so that the tip after the culm is pulled up. The side conveying action is performed extremely smoothly.

Moreover, the guide portion to be provided opposite to the lifting lug 26 of the endless lifting body 27 is located at the ridgeline portion 14a of the tip conveying frame 14.
Therefore, it is not necessary to form a special separate member as the guide part, and therefore the structure of the culm lifting and conveying device can be simplified as a whole, and it can also be made smaller. It is something.

Furthermore, as is clear from the above explanation, in the device of the present invention, the culm is reliably scraped up by the front end of the pulling device and the tip conveying device, so unlike the conventional device, the culm is scraped together at the front end of the pulling device. Even if there is no intermediate stem at the front end, the two-stranded culm is reliably brought into the lifting action area of the lifting device, and it.

It is reliably pulled up by a lifting device having the simplest structure, which consists of a series of endless bodies 27 having lifting lugs and a ridgeline portion 14a of the ear tip conveying frame placed opposite thereto. On the tip side of the husk culm, as described above, a tip conveying device consisting of an endless body having lugs and a guide rod has its front part wrapped by the pulling device, and its rear end is wrapped around the tip of the culm supply port. Because it extends to the side with a gentle inclination, the tip side of the culm can be transported extremely smoothly during the conveyance period from before harvesting of the stock base, and during the transportation, the head side of the husk can be transported very smoothly. From there, you can smoothly change your posture to lie on your side.
