Description

[Detailed description of the invention] Industrial application field: Regarding attachment devices for attached working machines, etc. of agricultural machinery,
For example, it is used to attach to the main body of a work machine that shreds threshed grain culms in a harvester or the like.

Problems to be Solved by the Invention In order to attach the working machine to the main body of the harvester, a pivot is provided on one side of the main body and the working machine, and a locking device for engaging the two is provided on the other side. In the case of a mounting structure with a mounting structure, it may be difficult to fit the shaft into the hole of the pivot when first pivoting the work machine to the pivot, or when removing the work machine, or when removing the work machine, it may be difficult to fit the shaft into the hole. There are problems such as interference with the shaft and difficulty in removing the shaft.Furthermore, when trying to lock the work machine with the locking tools, the installation accuracy of each locking tool or distortion of the parts may be affected. Therefore, there are problems such as difficulty in engaging each of the locking tools.

Means for Solving the Problem This invention provides a mechanism for connecting pivot parts 5 and 6, which are made up of boss parts 1 and 2 and shaft parts 3 and 4, which can be freely rotated around an axis in the vertical direction and fitted into and removed from each other, to a main body 7 of the fuselage. A pair of upper and lower pivot parts 5 and 6 are arranged between the upper and lower pivot parts 5 and 6, and the working machine 8 that is attached to and detached therefrom is arranged in a pair of upper and lower parts with an appropriate distance between the upper and lower sides, and the respective fitting clearances 9 and 10 are relatively large and small between the pair of upper and lower pivot parts 5 and 6. Differently, the structure of the agricultural working machine mounting device is such that the rotation axis A of both the upper and lower pivot parts 5 and 6 is swingably provided.

Effects and effects of the invention When attaching the work machine 8 to the machine body 7,
The shaft parts 3 and 4 of the work machine 8 are inserted into the boss parts 1 and 2 of the main body 7 from above, but at this time, the fitting clearances 9 and 10 of one of the upper and lower pivot parts 5 and 6 are inserted. If the pivot part on the other side is fitted based on a small pivot part, the other side will have a large fitting play, so it will be easy to insert it, and conversely, even when removing it, the pivot part with a small fitting play will be used as the standard. It can be easily removed by lifting the working body 8. Also, after the work body 8 is pivotally attached to the body 7, when rotating it to the joint of the body 7 and locking it with a locking tool, etc., the upper and lower pivot parts 5,
6 allows the rotation axis A to swing relative to each other, so that the locking tool on the main body 7 side and the locking tool on the working machine body 8 side can be easily engaged with each other.

Embodiment In the illustrated example, the threshing device 7 for threshing and sorting grains has a dust exhaust port 11 on the lower side discharging straw waste toward the rear in the center of the rear surface, and a sorting device is installed inside the threshing device 7. Forming the rear surface of the chamber 12, on one side of the rear surface 12 of the sorting chamber, there is a rear wall 13 having a grain storage section on the front side, and on the other side there is an interlocking chamber 1 with an interlocking mechanism installed therein.
4 are arranged respectively, and from the upper surface of the sorting chamber 12, there is provided a straw evacuation device 15 with a chain-linked structure that is inclined toward the rear wall 13 and protrudes rearward, and furthermore, on the upper side of this straw evacuation device 15, A cover 16 covering the upper side and one side of the grain threshing device is provided extending to the rear surface of the sorting chamber 12.

A working body 8 is provided, which has both side walls 17 and 18 of the body width extending from the interlocking chamber 14 to the rear wall 13, and is formed of a cover that covers the upper and rear surfaces. A cutting blade shaft 20 having a large number of cutting blades 19 arranged therein is rotatably supported on both side walls 17 and 18, and an interlocking pulley 21 is fixed to the outside of the side wall 18 at one end of the shaft 20. Further, from the side end of the rear cover of the working body 8 on the pulley 21 side, a supporting leg 22 having a disk portion at the lower end is provided to protrude downward.

At the side end of the rear wall 13 of the threshing device 7, there is a pair of upper and lower boss portions 1 and 2 having through holes in the vertical direction.
are provided at appropriate intervals, and a pair of shaft parts 3 and 4 having shoulders that can be fitted only from above into the pair of boss parts 1 and 2 through-holes are arranged at the front end of the side wall 17 of the work machine 8. However, in the lower pivot part 6, the fitting clearance is larger than that in the upper pivot part 5 by making the shaft part 4 a small diameter or by making the through hole of the boss part 2 a large diameter. Brings 10. Further, locking tools 23, 23 capable of locking the working body 8 when the working body 8 is joined to the rear part of the threshing device 7 are provided on the rear wall of the interlocking chamber 14 and the side wall 18 of the body 8. Provide each.
