Description

[Detailed Description of the Invention] The present invention relates to a straw removal device of a threshing machine suitable for a combine harvester, etc., and a support device for a straw removal portion such as a straw removal cover.

Conventionally, one end of the support frame of the straw removal section of this type of threshing machine was fixed to a side plate on the side of the culm removal port of the handling chamber, and was projected in a cantilevered manner onto the straw removal path.

However, on the other hand, since the weight of the straw removal conveyor and its cover is extremely large, the entire load of the straw removal part is concentrated at the attachment part to the side plate, so many auxiliary plate reinforcing stays etc. are welded between them. As a result, it required a large number of man-hours and materials, resulting in high costs, and had the disadvantage that the waste straw could get caught and cause problems with discharge.

On the other hand, it is desirable to use as thin an iron plate as possible for the structural members of the handling room in order to reduce the weight and cost of the machine.

Generally, on the handling opening side of the handling room, a frame member supporting the clamping rail is installed over the entire length, which helps support the handling room and allows for a strong structure. Since there were no replacement parts and it was weak, it had to be constructed to be particularly strong.

The present invention aims to eliminate the above-mentioned disadvantages all at once.In a threshing machine equipped with a straw conveying device on the discharge port side of the handling chamber, the front end is connected to the tip insertion part of the side plate on the supply port side. The rear part of a long frame, which is fixed at a side and whose middle part is supported on the side plate on the side plate on the side of the culm discharge port, is extended onto the straw discharge path, and a straw discharge conveying device is attached to the extending part of this frame, The above-mentioned handling chamber and the above-mentioned straw discharge path are covered with a series of covers that can be opened and closed and hinged on the side of the ear tip movement path, and the hinged portion of this cover is supported by the frame. .

The embodiment shown in the drawings will be explained below.1
1 is a handling barrel which is installed in a handling chamber 7 with a handling barrel shaft 2 pivotally supported by a front side plate 4 having a supply port 3 and a rear side plate 6 having a culm discharge port 5; An oscillating sorting body 8 is installed in the sorting air passage spanning the range.

Reference numeral 9 denotes a rail base which is fixed to the upper outer surface of the handling opening 10 and has a clamping rail 11 suspended thereon, and the operating side of the feed chain 12 facing the clamping rail 11 is supported and guided by a rail 13.

Further, the upper part of the front side plate 4 and the rear side plate 6 is a first
As shown in FIG. A hole 15 is formed by cutting and bending the inner and outer side plates inward and outward, respectively.

The support frame 16, which has a U-shaped cross section, has a length extending from the front end of the handling chamber 7 to the vicinity of the end of the straw conveyance path, and its front part is connected to the hole 1 of the rear side plate 6.
5 and support it, and the front end is inserted into the hole 14 of the front side plate 4.
The front end and the middle part are screwed to the cut and bent protrusions 17a, 17b, and 17c, respectively, and the cover receiver is welded to the side surface of the support frame 16 at the rear of the culm outlet 5. A protruding piece 18a provided at the front end of 18 is screwed onto the rear surface of the rear side plate 6.

In addition, a receiving net mounting frame 19 is screwed onto the portion of the support frame 16 located inside the handling chamber 7, and the upper receiving net 20 of the upper and lower receiving nets 20a and 20b is divided into two parts.
The upper edge of the receiving net 0a is fixed to the receiving net mounting frame 19, and the side edge of the lower receiving net 20b on the handling port 10 side is attached to the receiving plate 22 to which straw cutting blades 21 are fixed. The joint portion 20b is sandwiched and screwed between the receiving rod 23 and the holding plate 24.

Furthermore, there is a handling chamber 7 and a dust inlet 25 for discharging long straw, ear pieces, etc. generated in the handling chamber 7 onto the oscillating sorter 8.
As shown in FIGS. 5 to 7, the partition plate 26 that separates the
It is formed in a.

A straw removal frame 28 is fixed near the rear of the support frame 16, and includes a straw removal chain 27 stretched and supported. The cover 30, which extends over the straw conveyance route, is attached to the support frame 16 on the side opposite to the handling opening 10 with hinges 31, 31 so as to be openable and closable, and during work, it is fastened to the front side plate 4 and the rear side plate 6 with mounting screws 32, 32. When performing maintenance and cleaning of the inside of the handling room 7 and the straw transport route, remove the mounting screws 32 and open the cover 30, and the handling room 7 and the straw transport route will be opened. be completely liberated.

In addition, in the drawing, 33 is a second thrower, 34 is a direction plate extending from its upper edge to the second return passage, 35,
36 is a partition plate, 37 is a drive shaft of the straw conveyance chain 27, 38 is a cover that covers the second reduction passage side, 39 is a cover that covers the ear side of the straw conveyance path, and 40 is the above-mentioned device provided on the support frame 16. A notch 41 for attaching a bearing for the drive shaft 37 is a support arm connected to the rail base 9.

As mentioned above, the present invention is a threshing machine equipped with a straw conveying device on the discharge culm side of the handling chamber. The rear part of a long frame supported on the side plate's tip discharge side is extended onto the straw discharge route, and a straw conveyor is attached to the extended part of this frame, and the upper part of the handling chamber and the upper part of the straw discharge route are The tip movement path side is covered with a series of hinged covers that can be opened and closed, and the hinged part of this cover is supported by the frame, so the side opposite to the handling opening of the handling room does not have a rail base like the handling opening side, making it stronger. Although it is insufficient, the front and rear side plates are connected and strengthened by the long frame, and the overall strength can be improved without requiring any special auxiliary means.

Moreover, the part of the frame that supports the straw removal conveyance device becomes a part of the continuous beam, and the straw removal conveyance device can be used without using many reinforcing members unlike the conventional structure in which the base is fixed to the rear side plate in a cantilevered manner. Not only can the straw be firmly held, but the straw can be conveyed smoothly and in an orderly manner without getting caught and accumulating.

In addition, when removing clogs in the handling room or straw discharge path or carrying out maintenance inspections, a series of covers can be opened and closed at the same time, making it possible to easily and quickly carry out the maintenance inspections, etc. with high efficiency. Although the weight of the cover is extremely large, the long frame is used to firmly support the hinge part, which bears most of the weight when the cover is in a closed working state. Can be done.
