Description

[Detailed Description of the Invention] The present invention relates to a reaping and conveying device for a combine harvester, and in particular, the lower conveying chain, which pinches and conveys the culm side of the culm from the reaping side, is adjustable in vertical movement according to the length of the culm. To provide a simple structure that can be suitably carried out so that a sufficient amount of water can be taken, and the stock side can be smoothly transported without any hindrance.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the combine harvester, in which a threshing device A having a handling barrel 8, etc. is mounted above the machine frame 7 supported above the crawler 6.
are installed along the inner side of the width center side of the fuselage, a control tube 10 and a seat 11 are installed in the front right side of the fuselage, and a paddy receiving part 12 is installed behind them.

In front of the threshing device A, a reaping frame 2 is extended on the left side, and a reaping frame 2' is extended on the right side, and dividers 1 and 1' are installed at the tips of each.
The rear part 2a of the right side reaping frame 2' extends approximately in the front-rear direction.
' is bent and extended toward the rear part 2a of the left reaping frame 2, so that both frames 2, 2' have a substantially oval shape when viewed from the side, and both rear parts 2a, 2a' have a narrow interval. The rear end is connected by a connecting rod 13, and the fuselage frame 7
It is constructed so that a wide space C is formed on the right side of the rear portion 2a'.

Further, in a wide space near the front of both reaping frames 2, 2', a horizontal frame 14 is installed horizontally, and a cutting blade 15 is installed in front of the frame, extending forward from the middle of the horizontal frame 14. An intermediate divider 1'' is installed at the front end of the intermediate frame 16, and a thin case 17 is inserted between the rear parts 2av23' of both reaping frames 2 and 2' and connected by a connecting plate 18.
It is configured so that it can be input into the case 17 from the rear input section 19 and transmitted to each part.

At the rear of each divider 1, 1', 1'', both lifting cases 20, 20' are installed obliquely, and above the cutting blade 15, both star wheels 21, 21' are installed in parallel, and each A belt with protrusions 22, 22' extends diagonally forward from above,
The lower conveyor chain 4 is extended rearward from the upper rear side of both star wheels 21° 21', and the transfer conveyor chain 23 is extended from the upper end side of the chain 74 to the foot chain 9, and the transfer conveyor chain 23 is transferred from the lower conveyor chain 4. A tip conveyor 24 is configured to extend above the chino 23.

Further, the lower conveyance ceno 4 is installed so that it can move up and down in the space C on the right side of the rear part 2a' of the right side reaping frame 2'. , the lower drive case 5 near the starting end side of the lower conveyance cheno 4 is connected so as to be rotatable about the horizontal rotation fulcrum 0, and the space C of the drive case 5 is
The vertical movement of the lower conveyance cheno 4 can be adjusted by engaging an adjustment lever 25 extending from below the terminal end of the chevron 74 into a groove in the guide plate. Configure.

When the machine moves forward during combine harvesting work, each divider 1, 1', 1'' separates and raises the case 20.
．． 20' performs the lifting action, and then the protruded belt 2
2. 22' performs raking, and the cutting blade 15 reaps. Both star wheels 21 and 21' rak in, and the lower conveying cheno 4 takes over the culm side and conveys it in a pinched manner, and the cutting blade 15 reaps. The grains are transferred to the conveying chino 23, and the ear side is conveyed by the ear tip conveying body 24, and then passed from the receiving and conveying chino 23 to the foot chain 9, which is then supplied to the threshing device A.

When the culm changes to a long or short culm, the lower conveying cheno 4 is rotated vertically as shown by arrow A around the rotation fulcrum 0 to adjust the inclination by operating the lower conveying cheno 4 using the adjustment lever 25. By changing the clamping conveyance that is passed on to the inheritance conveyance cheno 23, it is possible to supply the culm with the same feeding depth regardless of the length or shortness of the culm.

In this state, the drive case 5 can move up and down in the space C without being obstructed by the reaping frame 2', etc., and the lower conveyor cheno 4 can also move up and down in the space C, so that the culm of the shell can be moved up and down. The original side is being held and transported without being disturbed.

In this way, the present invention has dividers 1 and 1 at the front, respectively.
The rear part 2a of both reaping frames 2゜2' on both sides supporting the
, 2a' are extended to one side, and both narrow rear parts 2a
, 2a', the lower drive case 5 near the starting end side of the lower conveyor cheno 4, which clamps and conveys the culm side of the culm from the reaping side, is set at a lateral rotation fulcrum O. The lower conveying cheno 4 and the driving case 5 are connected to each other so as to be able to rotate around the center, and the lower conveying cheno 4 and the driving case 5 are located at the rear part 2a of the reaping frame 2, 2'.

Since it is constructed so that it can move up and down while looking into the space C formed on the side of 2a', the lower conveyance ceno 4 can be fully adjusted up and down according to the length and shortness of the culm. In addition, the plant can be transported smoothly without any obstacles, and can be transported reliably and well regardless of whether the culm is long or short, and has the characteristics of being able to be carried out suitably with a simple structure.
