Description

[Detailed explanation of the invention] (a) Industrial application field The present invention relates to a string case structure for a combine harvester's straw tying machine and binder.

(b) Prior Art In the structure of the string case of a conventional binding machine, there is a technique as disclosed in Japanese Utility Model Application Publication No. 179633/1983 as a technique for arranging a partition plate inside the string case.

However, there is no technology that allows the use of large diameter strings and small diameter strings at the same time as in the present invention.

(c) The problem that the idea aims to solve The purpose of the present invention is as follows.

In conventional tying machines, the diameter of the string tube used in the tying machine, which is formed into a cylindrical shape by winding the string, is only small. However, in recent years, with small-diameter string tubes, the time that one string can continue working is too short, and the string has to be set many times while working on a single field, and the string ends up causing problems. Due to the dissatisfaction of having to worry about the string breaking, large-diameter string tubes with strings around twice the length of conventional string tubes began to be used.

This is only a problem with the diameter of the string tube and does not affect the performance of the tying device, so it can be used with any tying machine, but the size of the string case that stores the string tube is smaller than the conventional small diameter. Since the diameter of the cord was adjusted to match the diameter of the cord, there was a problem in that there was no place to store the large diameter cord.

The present invention is designed so that either type of string tube can be used, in view of the fact that a new large-diameter string has come to be used in addition to the conventional small-diameter string.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

The string case 1 that stores the strings of the tying machine is shaped to follow the overlapping outlines of the case where one large diameter string A is stored and the case where two small diameter strings B are stored. A partition plate pivotally supported on the inner wall by a hinge or the like is arranged along the string insertion direction, and when storing the large diameter string A, the partition plate is placed in a position where it contacts the inner wall of the string case 1, and the small diameter string When inserting and storing two pieces of B,
It is placed in the middle of the small diameter strings B, and the partition plate allows two
The movement of each small diameter string B is regulated.

(e) Embodiments and operations The purpose and structure of the present invention are as described above. Next, the operations of the invention will be explained in conjunction with the structure of the embodiment shown in the attached drawings.

Plan view of string case, No. 8
The figure is a plan view of a state in which a large-diameter string is stored.

The overall configuration of the straw tying machine for a combine harvester will be explained with reference to FIGS. 1 and 2.

A straw cutter 16 is attached to the rear surface of the threshing device of the combine, and a straw cutter 16 is attached to the rear surface of the straw cutter 16.
Furthermore, a straw tying machine C is attached. The present invention is the same as the conventional one in that a switching device is provided to select whether to use the straw removal cutter 16 or the straw removal binding machine C.

Straw tying machine C has 12 needles and 1 string holder.
3. The release rod 14 etc. are arranged above and below the binding deck 17, and the binding transmission case and binding transmission case 1
It is driven by 0 etc. By loosening the lock lever 18 shown in FIG. 1, the straw tying machine C can be slid from side to side to adjust the tying position.

The string case of the present invention is attached to the right outer surface of the binding transmission case 10 of the straw binding machine C,
It is configured so that it can be slid left and right together with the straw tying machine C. At the rear of the straw tying machine C, there is a three-dimensional discharge device 15 for three-dimensionally discharging the bundled straw after being bundled by the straw tying machine C into the field.
has been extended.

Next, according to Figures 3, 4, and 5, the string case 1
I will explain the mounting structure and the cord breakage sensor 8.

The string case 1 of the present invention is configured so that it can be removed from the straw binding machine C when the combine harvester is running on the road, and the large diameter string A and the small diameter string B can be set in the removed state. This is because if the large-diameter string A is configured to be storable, the diameter of the string case 1 becomes large, and it cannot be placed in the space of the conventional straw tying machine C, so it is attached to the side of the straw tying machine C. That is, the mounting handle 5 is fixedly protruded from the string case 1, the mounting handle 5 is hooked onto the string case fixing bracket 9, and then fixed to the string case fixing bracket 9 with the lock screw 20. It is. In this way, by fixing the string case 1 to the binding transmission case 10 via the string case fixing bracket 9, the part of the binding transmission case 10 can be easily attached to the needle 12 even in the straw tying machine C which is accompanied by large vibrations. Since this is a part far away from the cable and discharge rod 14, etc., and close to the part fixed to the slide frame by the lock lever 18, there is not much vibration. There is the least possibility of tangles occurring.

A string breakage sensor 8 and a string brake 11 are arranged on a string case lid 4 that closes the top surface of the string case 1. After the string M is taken out from the take-out hole 4a of the string case lid 4, it passes through a string brake 11 and an appropriate tension is applied to the string M. The string brake 11
The braking force can be adjusted using an adjustment knob 11a.

After passing through the string brake 11, the string M is passed through the string tensioning guide rod 6 and reaches the needle 12 via another guide rod. Conventionally, the string case was placed under the bundling deck 17 of the straw bundling machine C, so
A string breakage sensor 8 was also placed in this area, but in this embodiment, a string breakage sensor cover 7 is placed on the string case lid 4 to cover the string brake 11 and the base of the string tension guide rod 6. A string breakage sensor 8 is disposed inside the string breakage sensor cover 7, and the string tension guide rod 6 is moved by the spring force when the string tension guide rod 6 is wide open when the string breaks.
It is configured to be turned on.

The configuration of the string case 1, partition plate 2, and partition plate 3 will be explained with reference to FIGS. 6, 7, and 8.

The string case 1 has a shape that traces the outer shape when two small diameter strings B are arranged as shown in FIG. 7, and the outer shape when one large diameter string A is arranged as shown in FIG.

Therefore, the planar outline of the string case 1 is an ellipse. A partition plate 2 and a partition plate 3 made of band-shaped spring plates are arranged inside the oval string case 1. The partition plate 2 is pivotally supported by hinges 2a, 2b at both ends, and the partition plate 3 is also pivotally supported by hinges 3a, 3b at both ends.
If the partition plates 2 and 3 are pivotally supported at both ends by hinges, it may appear that they cannot be moved to the state when the large-diameter cord A is stored as shown in Fig. 8, but in reality, the partition plates 2 and 3 are supported by thin spring plates. Because of its structure, it can be bent, and by bending it from both ends or the center and gradually deforming it, it can switch between the state shown in FIG. 7 and the state shown in FIG. 8.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, since it can be used with the small-diameter string B, which has been used conventionally, or the large-diameter string A, which has recently been used, the method of use can be tailored to the operator's preference. Furthermore, when a large diameter string A is used, it can be used for a long time without worrying about the string breaking.

Second, by arranging the partition plates 2 and 3 on the inner wall of the string case 1, the string tube does not move when the small diameter string B is used, and the string can be prevented from collapsing.

Thirdly, when using small diameter string B, two small diameter strings B can be accommodated, one side can be used as a spare and a string, and even when the string ends, the next string can be set immediately. It is.
