Description

[Detailed Description of the Invention] The present invention relates to a tying device for a combine harvester which is provided with a tying section and a tying string storage section at the rear of a threshing device, and more particularly to an improved technique for the tying string accommodating section.

Conventionally, in order to construct a binding cord storage section, the upper half of a cylindrical body is constructed as a lid body that can be opened and closed, and a brake for the cord is attached to the fixed end surface of one end of the cylindrical body. When replenishing the brake, the string is passed through the brake from the cylindrical body, and the binding string is then stored. However, it is difficult to operate due to space constraints, and passing the string through the brake from the cylindrical body is difficult.
Also, while inserting the string through the brake, the binding string cannot be stored inside the cylindrical body, so you may have to hold the binding string with one hand.
It is necessary to place the binding cord at an appropriate location and insert the binding cord into the brake, and as a result, replenishing the binding cord becomes time-consuming.

In view of the above-mentioned points, it is an object of the present invention to provide a string storage section of an agricultural binding device that is easy to replenish the storage section with binding cords and is user-friendly as a whole.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A walking type combine harvester is equipped with a binding device 2 at the rear of the threshing device 1, and the threshed waste straw is made to flow down from the end of the feed chain 3 over the guide plate 4, and is collected in the binding section 6 by the scraping packer 5. Then, the sensing door I senses that a predetermined amount of the bundle has been focused, supplies the binding string from the lower string supply section 8 to the upper knot section 9 and ties it up, and the release tool 10, which rotates integrally with the sensing door I, It is configured so that it is released towards the rear of the aircraft.

A string storage part 12 for the binding part 6 is provided below the binding part 6 and on the support frame 11 of the binding device 2, and a brake 13 is used to store the binding cord in this string storage part 12, which is made up of a tube with a bottom. The cord is held by the needle 14 of the cord supply section 8 via the needle 14, and when the cord is fed out by the needle 14, the brake 13 presses and clamps the cord. This structure is designed to prevent troubles such as loosening or getting entangled with other movable devices.

The string storage portion 12 is configured to have a cylindrical shape to accommodate the string roll 15 wound in a cylindrical shape, and the string storage portion 12
A suppression biasing plate 16 is provided on the front side of the body to prevent the stored string roll 15 from shaking, and an opening 17 for replenishing the storage portion 12 with string is provided on the rear end surface of the body.

A lid 18 is provided on the opening 17 so as to be able to swing open/close and be fixed, and the opening/closing lid 18 is also provided with an inlet 19 for drawing out the string from the storage section 12 and the string brake 13.

In the figure, reference numeral 20 denotes a locking mechanism for fixing the opening/closing lid 18 with the opening 17 closed, and is pivotally connected to the string storage portion 12 so as to be swingable around the horizontal axis 1, and a compression spring 21 is attached to the locking mechanism. By pushing, pulling and rotating the operation lever 22, which is shaped into an abbreviated shape and which is always pressed toward the closing side of the open/close lid 18, the open/close lid 18 is allowed to swing. The lid 1 is placed between the protrusions 23 and 23 connected to the lid 1.
8 is fixed in the closed position.

The above are examples of the present invention.

As explained in this embodiment, the structure and the above features of the present invention include a binding part 6 and a storage part 12 for storing the binding string at the rear of the threshing device 1.
In the combine harvester binding device, the storage section 12 is constituted by a bottomed tube, and the string replenishment opening 17 of the bottomed tube is provided.
A lid 18 that can swing open and open is attached to the lid 18, and this opening/closing lid 18 is provided with an inlet 19 for the string supplied to the binding section 6 and a brake 13 for preventing excessive introduction, and the opening/closing lid 18 is fixed in a closed state. The locking mechanism is provided with a locking mechanism that is rotatable around an axis 4 along the longitudinal direction of the bottomed cylinder and slidably movable along the axis P of the bottomed cylinder. An L-shaped operating lever 22 that also serves as a lid fixing device is pivoted near the opening 11 of the bottomed cylinder and is formed by bending its free end at a substantially right angle, and this L-shaped operating lever 22 is connected to the axis pK. a spring 21 that presses the opening/closing lid 18 toward the closing side along the opening/closing lid 18;
The lever is formed in the portion of the lid 18 that is located within the circle when the free end side of the cursor-shaped operation lever 22, which is the part that presses and is also the handle part, is rotated around the axis 4. It is composed of a pair of small protrusions 23, 23 extending at a small distance in the front and rear.

Effects of this invention.

By pushing, pulling and rotating the operating lever 22, the lid 18 can be easily opened and closed with a single touch, and the configuration for this purpose is also very simple.

Moreover, in order to open and close the string replenishment opening 17, the opening/closing lid 18 itself, which is originally provided with a relatively wide space, is provided with a string introduction port 19 and a brake 13, so that when replenishing the string into the storage section 12, The opening/closing space of the lid 18 can be used to insert the string into the inlet 19 and the brake 13, and the replenishment of the binding string can be easily carried out in a wide space.

Moreover, since the opening/closing lid 18 is located at the rear end of the machine, the binding cord can be inserted into the brake 13 in a large space at the rear of the machine, and the binding cord can be stored in the storage section 12. The brake 1 is applied to the opening/closing lid 18 in the open state.
3, it is now possible to insert the binding cord through the tube, making it extremely easy to replenish the binding cord.
