Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing processing device that controls the above-mentioned threshing in a combine harvester that reaps shell culms planted in a field and threshes the harvested shell culms.

This type of threshing processing equipment is equipped with a culm transport and supply device along the length of the handling barrel on one side of the handling room, and the reaped culm is transported between the conveyor belt and the peg rail in this culm transport and supply device. It is configured to hold the stock part and transport the cut husk along the length of the handling cylinder while supplying it into the handling chamber for threshing.
Especially when the combine harvester becomes larger and the threshing processing equipment is also made to have a larger capacity, especially when the husk culm is very short or the husk culm is planted in the field under certain circumstances and the harvested husk culm is uneven. In some cases, the entire tip of the harvested culm with grains is allowed to enter the handling chamber, resulting in some inconveniences such as being left unhandled.

The object of the present invention is to avoid the above-mentioned disadvantages even in a large combine harvester equipped with a large-capacity threshing processing device, and to enable the combine harvester to be made large without any inconvenience. Specifically, it is an object of the present invention to provide a new threshing processing device for a combine harvester.

The combined threshing processing device of the present invention, which was developed in view of this problem, conveys the harvested husks along the length of the handling barrel by holding the stock base of the reaped husks between the conveyor belt and the clamping rails. At the same time, the conveyor band or the clamping rail of the shell culm conveying and feeding device that supplies the shell culm into the handling chamber is released from the shell culm clamp at the midpoint in the length direction of the handling barrel, and the entire amount of reaped shell culm is introduced into the handling chamber. It is characterized by providing a portion that can be selectively brought outside the shell culm conveyance path.

The first embodiment will be explained with reference to FIGS. 1 and 2. First, the illustrated combine harvester moves the machine body by driving the left and right crawlers 1, and divides the planted culm into 9 by the divider 2 at the front of the machine body. The planted culms are weeded, the culm pulling device 3 is used to pull up the planted culms, and the cutting blade 4 is used to cut the planted culms at the base of the plant. According to the present invention, the threshing device 7 is particularly configured as follows. That is, the handling cylinder 8 in this threshing processing device 7 is formed to be longer than usual. The reaped husk culms are fed into the handling chamber 10 in which the handling barrel 8 with the handling teeth 9 implanted is installed, as usual, through a feed chain 11, which is a conveying belt driven in rotation. The cut culm is held at the base of the stock between the clamping rail 12 which is provided along the line and is under the force of a spring 12a, and the feed chain 11 runs along the length of the handling cylinder 8 to move the cut culm along the length direction. This is carried out by inserting and feeding the tip side into the handling chamber 10 while conveying the feed chain 11. In particular, the feed chain 11 has a first feed chain 11A located on the front side and a second feed chain 11A located on the rear side. The handling cylinder 8 is divided into two parts 11A and 11B that are connected in series at approximately the center in the length direction of the handling cylinder 8. The first feed chain 11A includes a sprocket wheel 13 and a sprocket wheel 13 provided at a forward position on one side of the handling chamber 10.
The sprocket wheel 14 is fixed in its position by being suspended from another sprocket wheel 14 provided substantially at the center of the handling chamber 10 on the one side in the length direction. On the other hand, the second feed chain 11B is provided at a rear position on one side of the handling chamber 10 and the sprocket wheel 15 which is overlapped with the other sprocket wheel 14 in the transverse direction of the machine body. Although it is provided so as to be suspended from another sprocket wheel 16,
Shafts 15a and 16 of both sprocket wheels 15 and 16
a is connected by an arm 17 that rotatably supports both shafts 15a and 16a at both ends, and this arm 17
After. By rotating the front sprocket wheel 16 upward about the shaft 16a, the front sprocket wheel 15 is lifted to the position shown by the dashed line in FIGS. 1 and 2, and the second feed chain 11B is similarly moved to one point. It is designed so that it can be brought into a forward and upwardly inclined position in which the culm inheritance from the first feed chain 11A is not carried out, as shown by the chain line. In order to fix the second feed chain 11B in a posture located on the shell culm conveyance path in series with the first feed chain 11A and in a posture located outside the shell culm conveyance path shown by the dashed line, an arm is required. The arm 1
This is done by fixing 7 with a fixture 19. As shown in FIG. 2, the receiving net disposed below the handling cylinder 8 is divided into a first receiving net 20 and a second receiving net 21 in front and rear. The first dust exhaust port 2 is located between the first and second feed chains 11A and 11B1 at the connection point position.
2, and a second dust exhaust port 23 is provided at the rear end of the second receiving net 21.

In FIG. 2, 24 is a swinging sorting device provided from below to the rear of the receiving nets 20, 21. This swinging sorting device 24 is connected to a chaff sheave 25 located below the first receiving net 20. , a grain sieve 26 below the chaff sieve 25, and a first sieve 26 that receives waste from the first dust exhaust port 22.
The straw rack 27 includes a straw rack 27, and a second straw rack 28 that receives the waste from the second dust outlet 23. In Figure 2, 29 is a karawine, 30
31 is the first exit, 31 is the second exit, and in Figures 1 and 2, 32 is the waste straw chain for carrying out waste straw after threshing;
Reference numeral 3 denotes the clamping rail, and in FIG. 1, 34 denotes a waste straw processing device which is supplied with waste straw by a waste straw chain 32 and shreds or collects the waste straw. Since the threshing processing device 7 shown in FIGS. 1 and 2 is constructed as described above, the culms planted in the field are relatively long, and the culms that are planted in the field are not very bent and are neatly arranged after reaping. In the state where the feed chain 11B is fed directly, the second feed chain 11B is positioned on the extension line of the first feed chain 11A as shown by the solid line in FIG. 1 and the two-dot chain line in FIG. While the cut husk culm is held between the feed chain 11 and the clamping rail 12, the tip side of the cut husk culm is fed into the handling chamber 10, and the same threshing process can be carried out in most cases.

On the other hand, if the shell culms planted in the field are extremely short, or are considerably bent and are supplied unevenly after harvesting, the following should be applied to such shell culms. Threshing without leaving any unhandled grain can be done as follows.

That is, in such a case, the second feed chain 11B is placed outside the culm conveyance path as shown by the dashed line in FIGS. Until reaching the end of the first feed chain 11A, only the tip side of the cut culm held between the feed chain 11A and the clamping rail 12 is fed into the handling chamber 10, but at the end of the first feed chain 11A, Since the front end of the feed chain 11B of No. 2 is removed from the terminal position, the shell culm holding action is eliminated, and therefore the shell culm is drawn into the handling chamber 10 by eight rotations of the handling cylinder, and in the rear half of the handling chamber 10, the shell culm is The entire amount is supplied into the handling chamber 10. Therefore, even for very short culms or irregularly husked culms such as those whose panicles are placed on the chain 11 side, complete threshing is carried out in the rear half of the handling chamber 10, where the entire amount is put into the handling chamber 10, with no leftovers. In the illustrated case, the first half of the handling chamber 10 into which a part of the culm is introduced or partially supplied, and the handling chamber 10 into which the entire amount is input or supplied.
Dust is discharged separately from the inner rear part through the first dust exhaust port 22 and the second dust exhaust port 23, respectively, and the discharged material is processed in separate straw racks 27 and 28. Therefore, it is customary to carry out sorting with enhanced sorting effect. Next, the second
To explain the embodiment, whereas in the previous embodiment the feed chain 11 was divided into two parts 11A and 11B,
In this second embodiment, the feed chain 11 is integrated along the entire conveyance supply path, and the clamping rail 12 is divided into a first clamping rail 12A on the front side and a second clamping rail 12B on the rear side. The second clamping rail 12B is rotatably supported around a fulcrum shaft 35 at the rear end. In this second embodiment, when harvesting very short culms or oblique culms, the second clamping rail 12B is rotated downward around the fulcrum shaft 35, as shown by the dashed line in FIG. The front end side of the second strapping rail 12B is removed from the extension line of the first strapping rail 12A, and the posture is fixed for use. Since the shell culm clamping action is released at the end of the rail 12A, the entire amount of shell culm is fed into the rear half of the handling chamber 10, as in the previous embodiment. In the above embodiments, a part of the feed chain 11 or the clamping rail 12 is brought out of the shell culm conveyance path by rotationally displacing the part 11B or 12B. Of course, a portion of the feed chain 11 or the pinning rail 12 may be removed to bring it out of the culm conveyance path by sliding a slide. However, it is good.

FIG. 4 shows a third embodiment configured in this manner, and in this third embodiment, a part of the clamping rail 12 is provided with:
A detachable part 12c is provided which can be detached by removing the fixture 36,
The culm planted in the field is relatively long, and
If there is not much inversion, attach and use the removable part 12c as shown in Figure 4a.Conversely, if the culm to be planted in the field is extremely short or if it is quite inverted, If this is the case, the attachment/detachment part 12c is removed by removing the fixture 36, as shown in FIG. 4b, and then used. As described above, the threshing processing device for a combine harvester of the present invention has a state in which only the leading end of the reaped husk culm is inserted and supplied into the handling chamber over the entire length of the handling chamber, and a state in which only the leading end of the reaped husk culm is inserted and supplied in the front half of the handling chamber. It is designed so that it can be used by selectively switching between inserting and feeding only the side into the handling chamber and feeding the entire amount of cut husk into the handling chamber in the latter half of the handling chamber. ．． This switching is performed depending on the condition of the shell culm to be used, and if the shell culm is relatively long and does not have an inverted shape, long straw can be obtained in an orderly manner for straw use, as in the case of a normal self-threshold threshing machine. On the other hand, when the shell culm is extremely short or has an inverted shell culm, it is possible to achieve threshing without leaving any unhandled grain by putting the entire amount into the rear half of the handling chamber, which makes a big contribution especially to increasing the size of the combine harvester. It is used as a threshing processing device.
