Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a harvester in which a threshing section can be freely swiveled left and right with respect to a traveling section.

[Problems to be Solved by Prior Art and Invention] Conventionally, in a harvester, a work machine platform equipped with a threshing unit and a traveling unit are integrally assembled, so that, for example, an effective working space can be secured due to a narrow ridge. In the case of dust or direct dust on the worker due to wind direction,
It has the drawback of being inferior in workability because it is necessary to change the orientation of the aircraft one by one.

Therefore, as shown in Japanese Utility Model Publication No. 51-41794, there is a threshing part configured to be rotatable in the left-right direction with respect to a running part, and the above-mentioned drawback is attempted to be solved. The power transmission to the transmission case and the transmission case to the transmission case provided in the running section are branched from the gear case provided at the center of turning, so there are many parts and the structure is large. The problem is that it cannot be complicated and the aircraft also becomes large, and it is necessary to improve it further.

[Means for Solving Problems] The present invention has been devised with the object of providing a harvester capable of eliminating these problems in view of the above-mentioned actual circumstances. In order to make the working machine platform on which the threshing part, which is equipped with Karahomi inside the section, is mounted so that it can rotate in the left-right direction with respect to the running section, the Karohitsu shaft configured as the power input shaft of the threshing section is used. While crossing the turning center line of the running part, an intermediate shaft linked to the transmission case on the running part side is provided so as to match the turning center line, and the Kara shaft is linked to the engine and the intermediate shaft respectively. In addition, the power transmission mechanism from the engine to the transmission case is configured to pass through the Tara shaft.

According to the present invention, the power transmission to the transmission case is carried out by effectively using the Karato shaft of the threshing section.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a crawler type traveling body (traveling portion) provided in a harvester, and a cylindrical support shaft 3 is integrally attached to a traveling portion base 2 integrally provided on the traveling body 1. Has been. On the other hand, the engine unit 5 and the threshing unit 6 are mounted on the work implement base 7 in a front-rear parallel manner, and the work implement base 7 has a through hole 7a in which the upper end of the spindle 3 is located. The support shaft 3 is rotatably fitted around the shaft center, and the shaft center of the support shaft 3 becomes the turning center line O of the threshing unit 6. Moreover, although the bracket 9 is integrally provided in the through hole 7a, the turning center line O is the shaft (Kara shaft) 10a of the Karamoto 10 installed on the side of the threshing unit 6 facing the engine unit 5. Are arranged so as to face the substantially central position in the axial direction of the. Then, a bevel gear 11 integrally provided at a substantially central portion of the Karako shaft 10a meshes with a bevel gear 12a provided at an upper end portion of an intermediate shaft 12 rotatably supported in the bracket 9 and the support shaft 3, The Karato shaft 10a and the intermediate shaft 12 are interlockingly connected. Further, a bevel gear 12b provided at the lower end of the intermediate shaft 12
Engages with a bevel gear 15a provided at the tip of a transmission shaft 15 extending from the transmission case 13 side to the middle via an interrupting clutch 14, whereby the Karako shaft 1
A power transmission mechanism from 0a to the transmission case 13 via the intermediate shaft 12, the transmission shaft 15, and the interrupting clutch 14 is formed.

On the other hand, an input pulley 16 and an output pulley 17 are provided at one end portion protruding from the threshing portion side plate 6a of the Karato shaft 10a, and an output pulley 18 for an attachment (for example, a member such as a cutter) is provided at the other end portion. The input pulley 16 is interlockingly connected to the engine side via a belt 19 so that power from the engine side is input. Output pulley 1
From 7, the power transmission by the belt 25 is performed to the operating parts such as the handling cylinder 20, the second object conveying body 21, the first object conveying body 22, the dust collecting fan 23, and the hood 24, but The belt clutch 25 is switched between tight and loose by the shutter clutch 26 so that power transmission to these operating portions can be intermittent. 27 is a tension clutch 26
A threshing section lever for operation, 28 is a main clutch lever for operating the intermittent clutch 14. Reference numeral 7b is a roller that assists the turning of the work implement table 7.

In an embodiment of the invention constructed as described,
The work implement base 7 has a posture in which the engine unit 5 is at the rear and the threshing unit 6 is at the front with respect to the traveling unit 1, and traveling and general threshing work are performed in this state, but a narrow ridge Therefore, when performing threshing work in a place where a sufficient working space is not available or in a bad wind direction, the work implement base 7 is rotated to the center of rotation O.
It is possible to improve the working condition by turning to the right or left side around the center at a desired angle.

In the case where the present invention is implemented in this way, by turning the work implement table 7, it is possible to perform threshing work in the most desirable form, and improve workability and work environment.
It can be easily and easily measured without turning the entire machine one by one, but the turning center line O intersects at a substantially central position of the threshing section 6 in the axial direction of the Kara shaft 10a. The power from the engine unit 2 is transmitted to the transmission case 13 via the Karako shaft 10a. Therefore, the Karato shaft 10a, which is the input shaft of the threshing unit 6, is effectively used as the transmission shaft of the power transmission mechanism to the transmission case 13, and a dedicated gear box is provided as in the conventional case, and branched from here. Without a complicated power transmission system for transmitting the power from the engine section 2 to the threshing section 6 and the transmission case 13, respectively, a series of series from the engine section 5 to the threshing section 6 to the transmission case 13 is performed. Since a simplified power transmission system is formed, a dedicated gear box is unnecessary. As a result, not only can the structure be remarkably simplified, but the gear transmission part can be reasonably inserted into the threshing part, and therefore the stability can be improved without increasing the height of the fuselage. become.

By the way, such a harvester is used only at the time of harvesting stem culms, but as a farmer who owns a harvester, he usually owns a binder that operates a stalk culm, and makes both the seasons almost the same. Will be used. And when these harvesters and binders are not used, they will be stored in the barn almost at the same time, but if they are stored side by side in the barn, they will need their own areas. With the spread of machinery, securing storage space has become one of the concerns of farmers in recent years. Therefore, the harvester and the binder, which are always used simultaneously, can be stored in the upper and lower two stages as shown in FIGS. 4 and 5, so that the occupied area during storage can be substantially reduced. This is extremely convenient. That is, in this product, a support column 30 is erected on a lower base 29 capable of accommodating a bar hester so as to be rotatable around a vertical axis via a revolving base 30a, and an upper base 31 capable of accommodating a binder is provided there, and an upper part The table 31 is fixed to the chain 33 suspended between the sprockets 32 and 32a provided at the upper and lower ends of the column 30, and the chain 33 is moved by the operation of the handle 34 so that the spindle 30 serves as a guide. Make it move up and down. By doing so, with the upper base 31 in the lower limit position and on the side opposite to the lower base 29, the harvester is housed in the lower base 29, the binder is housed in the upper base 31, and then the handle If the upper base 31 is moved to a position higher than the harvester by the operation of 34, and then the upper base 31 is rotated together with the support shaft 30 toward the harvester side, the binder and the harvester can be stored in a two-layer stack structure. Therefore, it is possible to validate the occupied area during storage. Moreover, since the harvester and the binder are usually used as a pair, there is no problem even if this is done.

[Effects] In summary, since the present invention is configured as described above, by rotating the work implement platform with respect to the traveling unit, the threshing unit is moved to a desired position corresponding to the working conditions. It can be positioned very easily, and the workability can be significantly improved. Moreover, the turning center line of the work machine platform is arranged so as to intersect the Karato axis of Kara in the threshing section, and the power from the engine is transmitted to the transmission case via the Kara shaft. The power transmission from the Karato shaft, which is the input shaft of the Karato, to the transmission case is branched, so that it is dedicated to branching the power between the threshing section and the transmission case as in the past. No gear case is required at all, and a simplified power transmission system is formed which is effectively used for power branching of the Tangwan shaft. As a result, a significant simplification of the structure can be achieved and at the same time, in the threshing section. Therefore, it is possible to make the structure in which the power branch portion is naturally inserted in the threshing portion. Therefore, when the dedicated gear case is installed in the threshing portion, the threshing portion height is increased so as not to interfere with each member device of the threshing portion. Cormorants Do consideration there is no need, in the lightweight compact with, will be able to those low aircraft center of gravity stable.
