Description

[Detailed description of the invention] This invention is attached to the rear of the combine harvester, and when a certain amount of waste accumulates on the dropper fork, it is automatically dropped and released into the field by rotating the dropper fork downward. The present invention relates to an improvement in a dropper device configured to do so.

With this type of dropper device, when the waste straw is discharged into the field in a position perpendicular to the direction of travel of the long straw combine, when the combine makes a U-turn and travels to the next uncut area, the The part of the uncut land side of the waste straw that has been released into the adjacent already cut area will be trampled by the traveling device.

Therefore, in the past, various devices have been devised to prevent the above-mentioned troubles from occurring in the dropper device, and this device is one of them, and this device is an extremely simple device. By simply adding a device, you can remove straw and position the part on the uncut field side away from the travel trajectory of the combine harvester traveling in the uncut area. It is an object of the present invention to provide a dropper device that can be discharged into a field in an attitude tilted with respect to the direction of travel.

To explain the embodiment with reference to the figures, for the illustrated combine harvester, reference numeral 1 indicates a raising reaping device 9 disposed at the front of the machine body 2;
3 is a threshing machine mounted on the fuselage 2 in the rear direction, 4 is the foot chain, 5 is a traveling device equipped on the fuselage 2,
6 is a driver's seat, 7 is a dropper device attached to the rear of the threshing machine 3, and this dropper device 7 has a dropper fork 9 whose base end is pivoted 8 to the machine body 2, and this dropper fork 9 is always connected. 1 is a spring 10 for holding the straw in a horizontal position (the position shown by the solid line in FIG. 2), and a plurality of straw holding rods 11 whose base ends are fixed to the body 2; The side is held by a straw holding rod 11 extending near the tip 1 of the dropper fork 9, and the waste straw coming out of the threshing machine 3 is passed from the end of the foot chain 4 to the straw holding rod. When a certain amount of waste is deposited on the dropper fork 9, the dropper fork 9 is rotated downward against the urging force of the spring 10. The dropper device 7 is designed to automatically drop the waste straw onto the field (as shown by the chain line in Figure 2), but the dropper device 7 is further equipped with the following brake device 12' in accordance with this invention. has been done.

That is, among the plurality of straw retaining rods 11, the lower end portion 11a of the straw retaining rod 11 that is closer to the uncut field, and the lower end portion 11a of the straw retaining rod 11 that acts on the tip side of the harvested straw, is moved by the dropper fork 9. The lower end portion 11a of the presser rod 11 is extended at the lowest rotational position (chain line position) 1, and the brake acting portion 12a' (11a = 12a') of the brake device 12' according to this invention is ),
When a certain amount of waste straw is accumulated on the dropper fork 9 and the dropper fork 9 is rotated downward to position 1 shown by the chain line in FIG. However, the tip side receives the braking action from the brake acting part 12a' from behind and may fall into the field immediately. After that, it is made to move forward, and then it comes off the brake action part 12a' and falls into the field.

Therefore, in the dropper device according to this invention, as mentioned above, first the stock side of the waste straw falls into the field, and then, after a slight delay, the tip side is released from the brake device 1'2'. Brake device 1 on the side
Since the combine is moved forward together with the combine 11 hooked on the brake acting part 12a' of 2', the waste straw released into the field is moved forward along the head side of the plant, centered on the head of the plant, which has been brought into contact with the field first. Then, the ears are rotated in the direction shown in FIG.

Therefore, when the combine equipped with the dropper device of this invention makes a U-turn and travels to the next uncut area, it tramples the tip of the waste straw that was previously released into the already harvested area by its traveling device 5. There is no such thing.

In addition, in the dropper device of this invention, the direction of the tip side is changed by applying a brake to the tip side, which is lighter than the base of the stock. It is possible to drop the straw to the ground in an orderly manner with the direction of travel oblique, but its configuration is only a slight extension of a part of the straw holding rod that makes up the dropper device. , which can be implemented extremely easily and at low cost.
