Description

TECHNICAL FIELD The present invention relates to a harvester binding machine.

Conventional technology Conventionally, in order to facilitate post-treatment of culm in a harvester, etc., a binding machine is attached as an attachment on the culm exit side of a threshing machine, and after binding a plurality of threshed culms together, It is provided to be released to the outside of the aircraft. In such a case, an attachment frame is provided from a machine body frame having a threshing machine or a threshing side wall, and a binding machine is mounted thereon.

However, in order to assemble the mounting frame from the machine body frame, the installation position of the binding machine is at a high position in the vicinity of the threshing exit of the threshing machine. Moreover, even if the mounting frame is attached to the threshing side wall, the side wall itself is not so strong in terms of strength from the beginning, so that the threshing side wall must be installed in order to mount a relatively heavy binding machine. Not only is it necessary to add a considerable amount of reinforcement to the tying machine, but if the binding machine is designed to be slidable in the culm direction of the culm to change the bundling position according to the culm length of the material, the mounting frame itself will be large and There was no choice but to make it complicated, and the transmission structure also became complicated, which was a factor of cost increase.

Means for Solving the Problems Therefore, the present invention is a harvester that is located on the culm exit side of a thresher and has a spiral fried grain barrel obliquely installed from the lower front part to the upper rear part in the machine traveling direction, While supporting the binding machine slidably in the culm direction of the culm on the fried grain cylinder, a transmission shaft for driving the binding machine is provided along the fried grain cylinder, and the transmission shaft is provided near the lower end thereof. It is intended to solve the above-mentioned problems by being configured so as to be rotationally transmitted from a power direction changing device which is located at, and is transmitted from the thresher side.

Action Generally, a spiral-type fried cylinder has a structure in which a spiral transfer body is rotatably internally rotatably supported over the entire length of a thick and large-diameter iron pipe. There is. Therefore, by supporting the binding machine slidably in the stirrup direction on this solid fried cylinder, a special mounting frame for mounting the binding machine is unnecessary, and the mounting structure of the binding machine is extremely simplified and strong. Becomes Further, since the power transmission of the binding machine is provided along the fried food cylinder and is performed by the transmission shaft transmitted from the lower end side thereof, the power transmission structure of the binding machine can be simplified and the cost can be largely reduced.

Slides in the culm direction of the culm along the fried food barrel 8 via the slide screw 26, the screw holder 25 and the hanger 21, so that the bundling machine 11 can be set at a desired position according to the culm length to facilitate the bundling position. It can be changed.

By the way, the transmission shaft D is configured to be rotationally transmitted from the existing power direction changing device M. In the illustrated example, the existing power diversion device M is a structure that uses a lifting cylinder gear case 10 located near the lower end of the transmission shaft D and transmitted from the threshing machine 3 side. That is, as shown in FIG. 5, the fried-cylinder gear case 10 inputs power from the first spiral shaft 28, and the gear group 29 inside the gear case 10 redirects the power in the orthogonal direction to fried-cylinder 8 Although it is transmitted to the spiral transfer body 8a inside, the shaft portion of the spiral transfer body 8a is projected outward from the gear case 10, and the chain ring 30 is fixed to the projecting end, A transmission chain 31 is provided between the input chain wheels 22.

In the above configuration, the gear case 12 and the transmission chain case 14 of the binding machine 11 are the lower transmission shaft case 13 and the input shaft connecting pipe.
Since it is firmly integrated with 21, it does not require a frame or the like for supporting each part of the binding machine, and the binding machine 11 that is firmly integrated as described above is formed into a U-shape with the binding machine 11. Since it is slidably hooked and supported directly on the robust spiral-type grain lifting cylinder 8 via the hanger 24, a complicated and sturdy mounting frame such as the conventional binding machine mounting frame is not required, and the binding machine Although the mounting structure can be extremely simplified, a strong binding machine support structure can be obtained.

Moreover, since the upper side of the binding machine 11 is also supported by the threshing side wall 3a via the screw holder 25, the slide screw 26 and the plates 27, 27, the supporting action is further stabilized.

Further, a transmission shaft D for driving the binding machine 11 is provided along the fried food barrel 8, and the transmission shaft D is located near the lower end portion thereof and is transmitted from the threshing machine 3 side. Case 10
Since it is configured to be rotationally transmitted from, it is possible to simplify the arrangement structure of the transmission mechanism and the transmission shaft D to the transmission shaft D. Further, since the existing fried cylinder gear case 10 is used as the power direction changing device M, it is not necessary to separately provide a power direction changing device such as a bevel gear and the transmission shaft D itself to the binding machine 11 is expanded and contracted by the spline. Since the structure is flexible, the centering accuracy of the input shaft 23 and the input pipe shaft b forming the transmission shaft D is high, and the sliding action is smoothly performed when changing the binding position.

Since the slide screw 26 is separated from the threshing side wall 3b by removing a mounting bolt (not shown), the binding machine 11 can be easily and quickly attached and detached. The power direction changing device M may be something other than the fried-cylinder gear case 10.

Since it is configured to transmit power by rotation from a power direction changing device that is transmitted from the threshing machine side, a complicated support structure such as a conventional binding machine mounting frame is unnecessary, and the binding machine support structure is simplified. In addition, the transmission mechanism of the binding machine can be simplified and the cost can be reduced.
