DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a rotary weed culling hawk used in a combine harvester.

(Prior art) Conventionally, a hoisting device having a hoisting lug that is installed at the front position of a combine harvester and extending along a plane perpendicular to the machine's traveling direction is installed directly in the lateral direction of the machine in the machine's traveling direction. On the other hand, a forced weeding device is provided which has a weeding lug that rotates along a plane parallel to this, and when viewed from the side, the upper part of the weeding device undulates back and forth around the lower part. The spread-type weeding device for combine harvesters that can be raised and lowered freely was developed by Jiseki Sho 5.
It is described in Publication No. 1-161326 and is the third official publication.

(Problems to be Solved by the Invention) However, the above-mentioned known methods cannot prevent the stubble present on the side of the aircraft from moving in the direction of the aircraft.

Normally, the escape of the unstubbed stubble from the machine body is prevented by attaching a guide pestle called a narrow guide to the side of the machine body, but a narrow guide alone cannot be expected to have a sufficient effect of preventing escape.

In order to do this effectively, it is recommended to provide a weeding device with a pulling lug that extends in a plane parallel to the direction in which the aircraft is moving, and to have a structure that allows it to rise and fall freely outward. It is.

In this way, you can adjust the front and back and left and right sides in a combined manner, so you can directly check and ensure the best condition.

(Means for Solving the Problem) The present invention, which has been devised in view of the above, has a lifting lug 9 that is attached to the front side of the combine harvester and has a lifting lug 9 that rotates along a plane perpendicular to the direction of movement of the machine. A weeding device 10 having a weeding lug 26 that rotates along a plane parallel to the machine traveling direction A is provided on the side layer of the bag straightener 5, and the weeding device 10 includes:
It is installed so that it can freely rise and fall in the front, rear, left and right directions, so that when viewed from the front, the upper part rises and falls outward with the lower part as the center, and when viewed from the side, the upper part rises and falls forward and backward with the lower part as the center. This is a structure of a rotary weeding device used in a combine harvester.

A bevel gear 20 is fixed to the rear part of the shaft 19 of the gear 17, and a bevel gear 21 that engages with the bevel gear 20 is provided, and the rotating shaft 22 of the bevel gear 21 projects approximately horizontally in the direction of the uncut land side P. and attach sprocket 23 to its tip. The sprocket 23 is the lower sprocket of the weeding device 10, and as shown in FIG. 2, a chain 25 is wound between it and the paired upper sprocket 24, and a weeding lug 26 is attached to the chain 25. .

In FIG. 5, 27 is the gear 16, the gear 17 and the chain 18.
The case 27 is a case surrounding the bevel gears 20, 21.
Also surround. The case 27 is screwed onto a barrel tube 29 of a shaft fitting 28 which is fixed to the lifting device 5.

The shaft cylinder 29 has the same D as the shaft 14, and the outer cylinder 30 of the case 27 is rotatably iron-coupled to the shaft cylinder 29. Said case 2
7 and the scale fitting 28 are attached to the stopper 31 at a position removed from the shaft tube 29.
is fixed through the elongated hole 32.

Therefore, when the stopper 31 is loosened, the weeding device 10 can be raised and lowered in the left-right direction centering on the lower part by using the elongated hole 32.
33 is the same D as the rotating shaft 22, and the case 27
The shaft tube 34 that protrudes more is an outer vertical part that fits on the outside of the shaft tube 33, and the outer tube 34 is connected to the shaft metal fitting 3 fixed to the weeding device 10.
The shaft fitting 35 and the case 27 come into contact with each other at a position away from the rattan tube 33 and are fixed with a stopper 36.

37 is its deepest hole.

Therefore, when the stopper 36 is loosened, the weeding device 1 can be freely raised and lowered in the front and rear directions around the lower part of the river due to the outermost hole 37. (
Operation) Since the present invention has the above-described configuration, when the engine installed at a desired position of the aircraft is started and the aircraft moves forward, and each part is rotated, the stubble is separated by the grass cutting cover 4, and the aircraft advances. The falling stubble is raised by the lifting lug 9 which rotates along a plane perpendicular to direction A, the root is cut by the cutting blade device 6, and the stubble is raked and transported by the raking device 8. The grain is sent by the device 7 to the automatic feeding type threshing device 2 for threshing.

In this case, in the present invention, the weeding device 10 is attached to the side of the pulling device 5, and the weeding lug 26 of the weeding device 10 moves from the sprocket 12 at the lower part of the pulling device 5 to the shaft 1.
4 → Gear 16 → Chain 18 → Gear 17 → Shaft 19 → Bevel gear 20 → Bevel gear 21 → Shaft 22 → Sprocket 23
→ Chain 25 → Since the sprocket 23 is connected to the weeding lug 26, the sprocket 23 rotates, and the weeding lug 25 attached to the chain 25, which is wound between it and the upper sprocket 24 of the weeding device 10, rotates. This prevents the uncut stumps from moving toward the machine body by raking up the uncut stumps on the end-cut field side P with the weeding lug 26.

．． ``When viewed from the front, the weeding device 10 has an upper part that can be raised and lowered in the left-right direction around the lower part, and an upper part that can be raised and lowered in the front and back directions around the lower part when viewed from the side. Therefore, by making multiple adjustments, in the case of a grain that is strongly impatient with the fuselage side, the upper part of the grain can be slightly tilted outward and adjusted so that it lies backwards, etc. We will respond by making adjustments depending on the situation.

(Effect) Conventionally, a pulling device having a pulling lug that rotates along a plane perpendicular to the direction of movement of the machine, which is attached to the front side of the combine, is installed directly in the direction of movement of the machine. On the other hand, a forced weeding pupil having a weeding lug that rotates along a plane parallel to this is provided, and when viewed from the side, the weeding device has a structure in which the upper part undulates back and forth around the lower part. A rotary type weeding device for a combine harvester which can be raised and lowered freely is described in Jitseki No. 51-161326 and is well known.

However, since the above-mentioned known method only allows for-and-aft adjustment, it is not possible to adjust the degree to which the unstubbed stubble present in the legs of the aircraft is allowed to escape in the direction of the aircraft. However, in the present invention, the fuselage is attached to the side layer of the hoisting device 5, which has a pulling lug 9 installed on the front side of the combine harvester and extends along a plane perpendicular to the forward direction of the fuselage. A weeding machine 10 having a weeding lug 26 that rotates along a plane parallel to the traveling direction A is provided, and when viewed from the front, the weeding device 10 has a lower part centered and an upper part outward. The structure of a rotary weed thinning device in a combine harvester, which is installed so that it can be undulated in the front, rear, right and left directions, so that the upper part undulates back and forth with the lower part as the center when viewed from the side. Since the front and rear and left and right sides can be adjusted in combination, it is possible to ensure the optimum condition for the particular machine while actually working. death,
This has the effect of enabling even better adjustment.
