Description

[Detailed Description of the Invention] The present invention relates to a culm conveying device behind harvesting in a combine harvester.

That is, a lower conveyor chain that clamps and conveys the culm side of the shell culm from the reaping side is provided so as to be able to change the inclination freely according to the length of the culm. In a combine harvester configured to be able to feed shell culms, there is sufficient adjustment allowance for the lower conveyance cheno, and it is possible to take over and feed while properly conveying the lower part depending on the length of the culm, and the overall length of the machine is configured to be as short as possible. It is provided so that it can be carried out in a suitable manner.

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

FIG. 1 shows a surface survey of a combine harvester. A body frame 7 is installed above the crawler 5, and the body frame 7 is moved up and down by a hydraulic device 6 at the front with the rear part serving as a rotational fulcrum 0.
Threshing device A has a handling cylinder 8, a swing sorting body 9, etc. above.
The foot chain 3 in this device A is installed along the inner side, which is the width center side of the entire fuselage, and there is a recess 1 in the inner lower part of the fuselage below the foot chain 3.
0, a supply port 11 is formed above the front face portion 4 at the forefront of the fuselage, and a supply plate 12 is extended in front of the lower part of the supply port 11.

Dividers 13 are arranged in parallel at the frontmost part of the machine body in front of the threshing device A, and a double-drawing case 1 is provided diagonally behind the dividers 13.
4 and 14', a cutting blade 15 is installed horizontally, and protruding belts 17 and 17' are respectively extended to the left front from above both star foils 16 and 16' arranged in parallel above the cutting blade 15, A lower conveyor chain 1 is extended rearward from the upper part of the rear of both star wheels 16 and 16', and a conveyor chain 72 that inherits the culm side of the shell culm from the chain 1 is extended to the front of the foot chain 3, and The tip conveyor 18 is configured to extend from above the conveyance cheno 1 to above the inheritance conveyance ch 72.

Reaping frame 1 on the lower side of the star foil 16
Intermediate transmission case 21 is fixed to transmission case 20 fixed to 9.
The input case 22 at the lower part of the starting end 1b side of the lower conveyance chino 1 is connected to the rear upper part of the intermediate transmission case 21 about the lateral rotation fulcrum 0, and the input case 22 is connected to the upper rear part of the intermediate transmission case 21 to the vertical rotation fulcrum 02. The adjustment lever 23, which can be rotated around the center and is transmission-connected, and which is connected to the lower surface of the terminal end 1a of the lower conveying cheno 1, is engaged with each engagement groove of the guide plate to rotate the entire lower conveying cheno 1. Dynamic fulcrum 01, 02
Although it is installed so that it can be rotated and tilted at the center, if the lower conveyance cheno 1 is rotated and tilted downward depending on the long culm, the terminal end 1a
is the rear side of the front part 4 of the threshing device A, that is, the recess 10
It is constructed so that it extends downward and slopes.

A control tube 24 and a seat 25 are installed on the front right side of the whole machine, a paddy receiving part 26 is installed behind them, and a base cutter 27 is installed behind the threshing device A.

Therefore, when the machine moves forward during combine harvesting work, each divider 13 separates into two lifting cases 14, 14'.
is raised, and then the cutting blade 15 cuts while the protruded belt 17.17' scrapes, and then both star wheels 16.
16' is raked in, and the culm side of the shell culm is transferred to the lower conveyance chain 1, which pinches and conveys the culm side and transfers it to the inheriting conveyance chain 2, and the tip side is transferred to the tip conveyor 18. The culm side is taken over from the transfer conveyance cheno 2 to the foot chain 3 and supplied to the threshing device A.

When adjusting the supply depth to the threshing device A to be constant according to the length of the culm, operate the adjustment lever 23 to rotate and tilt the lower conveying cheno 1 around the rotation fulcrum 01.02. When the inclination is adjusted as shown in FIG. The clamping position can be changed, but
When the terminal end 1a is adjusted to be lowered as the culm becomes longer, the terminal end extends rearward from the front part 4 of the threshing device A, as shown in FIGS. 5 and 7, and the long culm becomes longer. It is taken over and supplied from the middle of the lower conveyance chino 1 to the inheritance conveyance chino 2.

In this way, the present invention provides a lower conveyance cheno 1 for pinching and conveying the culm side of the shell culm from the reaping side, which can be freely adjusted to change the inclination according to the length of the culm, and a transfer conveyance chino 2 from the rear end side of the chino 1. In a combine harvester configured to supply husks to the foot chain 3 of the threshing device A through the culm, when the lower conveying cheno 1 is adjusted to have a low inclination during long culm processing, the terminal end 1a of the cheno 1 is connected to the front surface 4 of the threshing device A. Since the structure is such that the lower conveying cheno 1 and the threshing device A are brought closer to each other so as to extend further to the rear side, the lower conveying cheno 1 can be sufficiently adjusted, and the lower conveying cheno 1 can be properly conveyed depending on the length of the culm. It has the characteristics that it is possible to take over and supply while carrying out the above, and that the overall length of the aircraft can be made as short as possible, and that it can be carried out suitably.
