Description

[Detailed explanation of the idea] The present invention relates to a waste culm processing device in a combine harvester.

This invention adjusts the threshing of the harvested husks using an automatic threshing device, and the threshed husks are shredded using a cutter and collected into a collecting body via the culm channel using a flip-up wheel. When a bag or other collection object is full, the cutter case at the bottom of the flip-up truck is opened during the work to replace it with a new collection object.
The cut culm is discharged to the outside from this opening, and the workability of attaching the collecting body is improved.

To explain the details of the embodiment with reference to the drawings, A is a combine main body, B is an automatic threshing device for the combine main body A, and the culm that has been threshed by the automatic threshing device BK is transferred to the rear part of the combine main body A by a conveying mechanism C. The paper is sent to a desk-type cutter D installed at the top, where it is shredded.

The desk-type cutter D is constructed as follows.

That is, a low-speed rotating shaft 2. The high-speed rotating shafts 3 are arranged parallel and horizontally, and the low-speed rotating shaft 2 is arranged on the forward direction side of the combine main body A.

Further, the low-speed rotating shaft 2 is provided with a plurality of rotary blades 4 having feeding action at appropriate intervals, and the high-speed rotating shaft 3 is provided with a high-speed rotating blade 5 that meshes with the feeding rotary blades 4. .

A flip wheel (beater) is installed on the lower side of the cutter mechanism section consisting of the feed rotary blade 4 and the high speed rotary blade 5.
6 is disposed, and its shaft 1 is mounted between the left and right frame plates 1.

As is clear from FIG. 3, both ends of the flip-up wheel 6 are configured to intervene in a recess 8 which is a circular part of the frame plate 1 and bulges outward. The culm shredded by the mechanism intervenes in the gap between the end of the flip-wheel and the frame plate to prevent the culm from wrapping around and damaging the blades or shaft, or from increasing the load. be.

Generally, the flip-up wheel 6 is surrounded by a guide plate 9 fixed to a bridge between the frame plates 1 from its lower outer periphery to the lower side of the feed rotary blade 4 constituting the cutter mechanism. There is.

In the middle part of this guide plate 9, as is clear from FIGS. 3 and 5, there are three opening/closing plates 1 whose left and right ends are sandwiched and the middle part is wide.
0a.

10b and 10c are provided, and this central opening/closing plate 1
The end edge of the combine main body side of 0b is rotatably connected to a support shaft 11 that is mounted between both frame plates 1.

The tip of an opening/closing rod 12 is in contact with the lower central portion of the central wide opening/closing plate 10b, and this opening/closing rod 1
The base of 2 is fixed to an operating rotation shaft 13 mounted between the left and right frame plates 1.

Further, one end of the L' aba-4 is fixed to the end of the rotating shaft 13 outside the frame plate 1 on one side, and a connecting rod 15 is connected to the other end of the lever 14 to form a side surface of the duct 16. The middle part is connected to the lower end of the operating lever 1T which is pivotally supported.

Reference numeral 18 is a spring for maintaining the click motion and rotational position of the operating lever.

As is clear from FIG. 5, long guide rails 19 and 20 are provided horizontally at the upper and lower ends of the opening/closing plate 10b, and the opening/closing plate 10a is attached to the long guide rails 19,20.

The upper and lower ends of 10c are fitted to form the opening/closing plate 10a.

10e can slide toward the central opening/closing plate 10b.

In the figure, reference numerals 21 and 22 indicate the opening/closing plate 10a. These metal fittings 21 and 22 are provided on the outer surface of 10c, and can be opened or closed to any degree by pinching them with your fingertips or by applying them to the tip of another operating rod.

The duct 16 is attached between both frame plates 1, and its base opening communicates with the culm side of the flip-wheel 6, and is oriented backward and upward at an angle of approximately 45 degrees.The duct 16 has an arcuate upper end. Release guide plate 23° Side plate 24 and rear guide plate 2
5, and a downward discharge port 26 is formed by these at the upper end of the duct 16.

An opening 27 is formed between the lower end of the rear guide plate 25 and the end of the guide plate 9, and this opening 2T is opened until the cut culm collection bag is full r/c' If the fx discharge port is blocked, the shredded culm is discharged to the outside from this opening 27, so as to prevent damage to the flip-up wheel and the like.

Reference numeral 28 denotes a windbreak plate suspended from the lower end of the rear guide plate 25. The windbreak plate 28 blocks the wind from the automatic threshing machine, and prevents the collecting bag attached to the receiver from being blown away by the wind. This is to prevent you from being exposed.

Further, the duct 16 and the mechanisms connected thereto are all removable from the frame plate 1, and can be replaced with conventionally known culm collection mechanisms, bundling devices, etc., although not particularly shown. It is possible to do so.

In order to use the culm collecting mechanism, a switching plate 29 that can be rotated in the vertical direction is provided above the desk type cutter D, and the rear end of this switching plate 29 is connected to the axis between the two frame plates 1. Further, the front end of the switching plate 29 can be connected and disconnected from the rear end of a receiving plate 31 which runs along the lower side of the belt 30 constituting the conveying mechanism C.

Then, it is possible to switch between transporting the discharged culm to the culm collecting mechanism or to the desk type cutter D.

Further, as shown in FIG. 2, the base of a bag hanging rod 32 is pivotally supported on the upper outer side of the both side plates 24 constituting the duct 16, and an engaging pin 33 is provided near the base of the bag hanging rod 32. It can be freely engaged and detached from the hooks 34 provided on the outer surfaces of the side plates 24, and when the two are engaged, the bag hanging rod 3 is attached as shown by the solid line.
2 is in a horizontal state, and when the tie is removed, it is in a hanging state as shown by the chain line, so that there is a danger that the bagging rod 32 may hit other objects and break while the combine main body is in operation for purposes other than work. This prevents

Reference numeral 35 denotes a collection bag, and a drawstring-like closure string 36 is attached to the upper opening of the collection bag, and a sealable spout 3I for draining and air venting is provided at the bottom of the old collection bag 35.

38 is a receiver on which the collection bag 35 is placed;
As is clear from the figure, 8 is formed in the shape of a rectangular frame plate.

The housing 38Fi is fixed to the upper surface of the rear end of the connecting rod 39, and the connecting rod 39 is attached to the support tube 40 provided on the main body A so that it can be moved back and forth. When in use, it can be stored in the position shown by the chain line.

In the figure, 41 is a tightening bolt.

It is preferable that the receiver 38 be supported not by one connecting rod but by at least two parallel connecting rods 39, that is, to have a structure that prevents the receiver from rotating.

In the figure, 42 is a swinging sorter, 43 is a dust discharge port, and 44 is a crawler.

Since the present invention is constructed as described above, it is possible to shred the threshed waste culm with a cutter and collect the shredded waste culm into a collecting body using a flip-up truck. Now, we have made it possible to fully open the opening/closing plate installed on the underside of the flip-up car at once by manually operating the control lever, so when the bags and other items to be collected are full, the opening/closing plate can be fully opened and cut. Do not let the waste culm fall directly into the field and supply the waste culm to the duct.

Therefore, there is an advantage that the work of removing a full collecting body and replacing it with another collecting body can be carried out smoothly and quickly.

Further, since the above-mentioned opening/closing plate is divided into three parts, namely 10a, 10b, and 10c, other parts except the tip can be opened by arbitrarily opening the opening plate 10at and 10c.

It is possible to optionally collect other parts of the culm except for the root, or other parts of the culm except for the tip and root, and it is possible to select the collection part of the cutting pit and collect it with a knife depending on whether it is to be used as fertilizer or feed. This has great practical effects.

The present invention has the effect that finer-grained string-cut culm release and recovery processing can be achieved by adjusting the degree of opening and closing of the opening/closing plates 10a and 10c in the left-right direction.
