The upper handle case can be lifted by lifting the handle.

[Problems to be solved by the invention]

During the threshing operation, the rotating handling cylinder tries to press the grain culm downward, so that the reaction force tends to lift the handling cylinder and the upper handling case upward. This allows
The engaging part of the upper handle case is attached to the locking part of the lower handle case
The structure is such that it firmly engages in the closed position.

Therefore, the engaging operation and the disengaging operation of the engaging portion by the handle are relatively heavy, and there is room for improvement.

It is an object of the present invention to obtain a structure that allows the upper and lower case cases to be lightly fixed and released.

[Means for solving problems]

A feature of the present invention is that the threshing apparatus as described above is configured as follows.

An upper handling cylinder, which is parallel to the swing axis, near the virtual arc passing through the locking part of the lower handling case, with the swing axis of the lower handling case being the center, and near the horizontal axis. An engaging part is provided to be swingable up and down around the axis of the case, and the operating arm extends from the engaging part to a position where it projects outward from the side wall on the feed chain side, and The positional relationship between the engagement portion and the engagement portion is set so that the engagement state between the engagement portion and the engagement portion is released by the rocking operation, and the engagement between the engagement portion and the engagement portion is set. The contact part that prevents the swinging operation of the operation arm from the position where the engagement is released further upward,
Prepared for the upper handle case.

[Action]

(I) When configured as described above, for example, as shown in FIG. 1, compared with the length from the shaft core (P ₃ ) on which the engaging portion (31a) is swingably supported to the engaging portion (31a). The length from the shaft core (P ₃ ) to the other end of the operation arm (31) can be made sufficiently long.

Therefore, by holding the other end of the operation arm, it is possible to easily engage or disengage the engaging portion with the locking portion by the action of the lever.

Then, as shown in the state of the chain double-dashed line in FIG. 1, the operation arm (31) is lifted up to operate the engaging portion (31a).
When the operation arm (31) is further lifted and operated after being disengaged from (30), the operation arm (31) abuts on the abutment portion (33) of the upper handling case (15). . As a result, when the operation arm (31) is further lifted up, the upper handling case (15) is lifted up together with the operation arm (31).

(ii) When the upper handling case (15) is lifted by the operation arm (31), as shown in FIG. 1, the swing axis center (P ₂ ) of the lower handling case (16) and the upper handling case are shown. The entire weight of the upper handle case (15) is applied to the shaft core (P ₃ ) and the contact portion (33) of the engagement portion (31a) on the (15) side.

In this case, the handling barrel (3), which is a heavy part among the respective parts of the upper handling barrel case (15), has the horizontal axis (P ₁ ) supported by the upper handling barrel case (15) and the engaging portion (31a). ) Is away from the axis (P ₃ ) of
It is necessary to sufficiently reinforce the portion of the side wall between the horizontal axis (P ₁ ) and the horizontal axis (P ₃ ).

In contrast, in the vicinity of the horizontal axis of the threshing drum (3) in the present invention (P _1), since the axis of the engaging portion (31a) (P ₃₎ is positioned, the horizontal axis (P The weight of the handling cylinder (3) hanging on ( ₁ ) remains the same as the engaging part (31a).
It will be in a state of hanging on the axis core (P ₃ ) of the horizontal axis core (P ₁ ) and the axis core (P ₃ ).
It is not necessary to reinforce the part of the side wall between and.

(iii) For example, as shown in FIG. 1, during threshing work, the upper handling barrel case (15) is moved by the reaction force from the rotating handling barrel (3) so that the swinging shaft core ( P ₂ ) is used as a fulcrum to try to be lifted upward in a circular arc.

In this case, in the vicinity of the virtual circle that passes through the locking portion about the pivot axis (P ₂₎ as in the present invention (30) (A), the axis (P ₃₎ of the engaging portion (31a) is When it is positioned, when the upper handle case (15) is about to be lifted by the reaction force of the handle body (3), it is close to the extension line in the direction of the force applied to the locking part (30). Shaft core of joint (31a)
(P ₃ ) will be located.

As a result, the force that tries to lift the upper handling case (15) does not come off, and the shaft center of the engaging part (31a) remains unchanged.
(P ₃ ), the upper handle case (15) is firmly fixed in the closed position.

Then, since no component force for removing the engaging portion (31a) from the locking portion (30) upward or downward is generated, the engaging portion (31a) is locked by the vibration during the threshing work (30). It doesn't come off.

(iv) With the configuration of the present invention, for example, as shown in FIG. 1, the swing displacement of the engaging portion (31a) is greatly enlarged, and the operating arm (3
It is expressed as the swing displacement at the other end of 1).

As a result, even if the engaging portion (31a) is incompletely engaged such that it is slightly disengaged from the locking portion (30), the operation arm (31)
The position of the other end allows the operator to easily recognize this incomplete engagement state.

[Effect of device]

As described above, in the threshing device that swings and opens the upper handling case up and down, the engaging and disengaging operations at the closed position can be easily performed, and the operability of opening and closing the upper handling case is improved. I was able to.

Since it is not necessary to particularly reinforce the side wall portion of the upper handle case that supports the handle and the engaging portion, a structure advantageous in terms of strength can be obtained.

Further, in the closed position of the upper handling body case, the upper handling body case can be firmly fixed by the engaging portion, and the engaging portion is not disengaged from the locking portion due to vibration or the like. Can be securely fixed in the closed position.

Further, the state in which the engaging portion of the upper handling case is completely engaged and fixed to the locking portion can be recognized by the state of the operation arm. It is possible to prevent a situation in which the lock portion is disengaged.
