Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding machine having a raking guide device adapted to bind the waste culms conveyed from the conveyor of the thresher with a slide type tie machine capable of moving and adjusting in the culm direction. Regarding improvement.

[0002]

2. Description of the Related Art Conventionally, a cutter and a bundling machine (hereinafter referred to as a knotter) are provided on the lower side of the culm carrier of a thresher in the carrying direction.
There is already known a culm transporting device that selectively feeds culms to a cutter or a knotter by switching a sandwiching rail opposite to this culm transporting body, and the culm feeding part of the cutter is already known. The cover that can be opened and closed is moved for sorting.

That is, the knotter is attached to the rear part of the cutter and provided so as to be able to move laterally in the direction of the culm, and by moving the knotter, the knotter is tied at a desired position on the root side or the tip side of the culm. I have to. Further, a cover for opening and closing the culm supply part of the cutter is provided so as to be openable and closable, and when the culm is sent to the cutter, the cover is opened and opened upward, and when it is sent to the knotter, it is closed. On this cover, a large number of culm guides are arranged in a row so as to be close to the scraper of the knotter, and the culm discharged from the end of the culm carrier is guided and guided by the culm guides and bundled. I am trying to do it.

[0004]

However, in the apparatus in which the knotter is laterally moved and adjusted in order to make the bundling position variable as described above, the knot guide and the scraper are allowed to move laterally. Since they cannot be brought close to each other or overlapped with each other and a predetermined gap is required between them, the gap causes trap leakage and culm which delays trapping. Furthermore, the culm cannot be smoothly guided to the feeding part of the scraping track of the scraping body and the packing track of the packer, and the knotting will cause the culm to be bound in a state where the feeding posture is disturbed. There is a problem that mistakes and clogging of the conveyance path of this part are likely to occur. Further, there is a drawback that the operation is complicated and inefficient because it requires a positioning operation for appropriately adapting the culm guide to the scraping body at an arbitrary position where the knotter is laterally moved.

[0005]

The binding machine of the thresher according to the present invention is constructed as follows. 1) A binding machine for a thresher provided with a binding machine for scraping and binding the culms sent from the end portion of the culm carrier 1b of the threshing machine 1 so as to be movable and adjustable in the culm direction of the culms. In the above, the culm guide 5 formed of a spring member is provided along the end of the culm carrier 1b so as to face the scraping body 33 in the scraping direction.
In a side view, the guide piece 51 and the mounting piece 52 are bent and formed in a folded shape, and the folded portion 53 is freely placed in a state of being brought close to the threshing machine 1 or the machine wall 2a of the cutter 2 mounted on the threshing machine 1. A lower mounting piece 52, which is an end, is fixed to the knotter 3 side, and an upper guide piece 51 is provided so as to be close to or wrap around the raking track of the raking body 33.

2) A guide rail 54 is provided on the machine wall 2a along the opening of the cutter 2, and the guide rail 54 covers the moving end of the guide piece 51. 3) Then, the culm guide 5 is manufactured by a leaf spring, and the guide pieces 51 are formed on both sides of the mounting piece 52 so as to have a bifurcated shape. It is facing the trajectory B of the body 33.

[0007]

[Operation] The culm which is conveyed and discharged from the culm carrier 1b is a guide piece 5 of a culm guide 5 extending from the knotter 3 side.
The guide member 1 guides and guides it to a position close to or overlaps with the scraping member 33, and the scraping member 33 performs an appropriate scraping action, and the knotter 3 satisfactorily binds the bundle.

The culm guide 5 moves integrally with the scraping body when the knotter 3 is moved laterally, and the tip end thereof is always kept close to the machine wall 2a of the cutter 2, so that the desired bundling position is obtained. In the above, good scraping and bundling can be performed without causing the culm to be caught.
