Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an opening/closing device for the upper cover of a threshing machine for threshing grain culms.

(b) Prior art Many devices have been known to open and close the upper cover of the handling barrel in the handling chamber, but in a threshing machine in which the processing chamber is installed on the side of the handling chamber, the upper cover of the handling barrel is opened and closed. There was nothing that opened and closed at the same time.

(c) Problems to be solved by the invention When the processing chamber is provided on the side of the processing chamber and the processing cylinder upper cover is provided separately from the processing cylinder upper cover, there must be an appropriate means to open and close the upper covers at the same time. Without,
There was no way to open them separately.

(d) Means for solving the problem The present invention is a threshing machine having a processing chamber on the side of the handling chamber, in which the upper cover of the handling trunk of the handling chamber is pivoted so that it can be opened and closed on the side opposite to the handling opening. The processing cylinder upper cover of the processing chamber is removably attached, and when the processing cylinder upper cover is opened and closed by an extremely simple method of connecting the processing cylinder upper cover to the processing cylinder upper cover with a frame, the processing cylinder upper cover is removed. The above-mentioned problem was solved by making it possible to open and close the door at the same time.

(E) Example An example of the present invention will be explained with reference to the drawings.
A dust inlet 3 is provided on one rear side of the handling chamber 2 in which the handling cylinder 1 is housed and mounted on a shaft. Transfer room 6
a and a processing chamber 6b following it.
A transfer spiral 10 is installed in the transfer chamber 6a of the processing shaft 9 supported by the processing shaft 9, and processing teeth 11 are installed in the processing chamber 6b.
A processing cylinder 12 having a processing cylinder 12 having It consists of a surface a and a surface b that slopes slightly inward, and the middle part is configured in a rectangular tapered shape with a surface c that slopes so that the rear part is lower and a surface d that tilts the rear part inward. is composed of a surface e that is parallel to the surface a and a surface f that is slightly inclined inwardly, and each of the surfaces a, b, c, d, e, and f are connected in series and engage removably. are doing.

The upper cover 16 of the handling trunk is constructed by fixing a cylinder cover 17 to the upper cover 18, and an arm 20 protruding from the rear side of the upper cover 18 is attached to a receiver erected on the upper plate integrated with the machine frame. Gold 21
An operation lever 23 is rotatably supported on a fulcrum shaft 22 and has a base fixed to the end of another fulcrum shaft 23a above the operating lever 23. When this thresher is mounted on a combine harvester, the operating lever 23 is pivoted toward the operator's seat 25. There are projecting pieces 22a, 22 which are provided on the front and rear parts of the fulcrum shaft 23a.
a is a hook 27, 27 pivoted by a receiving plate 24, 24;
is interlocked and connected to the operating lever 2 via the rod 26.
3 and the other end of the fulcrum shaft 22 are connected to the support plate 21 by strong tension springs 28, 28.
The hook 27 is rotatably supported by a stay on the top cover 18, and is engaged with pins 31, 31 protruding from the inlet side plate 30a and the outlet side plate 30b by weak springs 28a, 28a. is energized by

The front side of the top cover 18 and the processing cylinder top cover 15 are connected by a frame 32 which is U-shaped in side view.
The upper cover 16 side of the handling barrel may be fixed to a rail frame 34 from which a pinch rail 33 attached to the feed chain is suspended, as shown by dotted lines in FIG.

In addition, a blower fan 35 provided below the handling room 2
A oscillating sorting body 37 is installed in the sorting air path consisting of a suction windmill 36 provided on one side of the rear part, and the oscillating sorting body 37 has a wave-shaped conveyor belt facing the lower surface of the receiving net 38 of the handling cylinder 1. Plate 39 followed by flow plate 40 and corrugated transfer plate 4
1. It consists of a sorting net 43 that is connected to the terminal end and faces above the first receiving gutter 42, and a stroke rack 46 that faces above the second receiving gutter 45. A cross-flow fan 47 is provided.

In the above-mentioned threshing machine, the handling chamber 2 and the processing chamber 6b
When performing maintenance or inspection on the control lever 23, push down the operating lever 23 a little and move it laterally to remove it from the latch 48. The protrusions 22a, 22a at the base of the operating lever 23 engage with the fulcrum shafts 22, 22, and the upper cover of the handling barrel is removed. 16 is pulled up by a strong tension spring 28 on its handling opening side, so it rotates upward about the fulcrum shaft 22 as shown by the chain line in FIG. Since it is integrated with the handling cylinder upper cover 16 (or the rail frame), it is raised and rotated integrally with the handling cylinder upper cover 16 as shown by the chain line in FIG.
The processing chamber 6b is also opened.

In this state, maintenance and inspection of the handling chamber 2 and the processing chamber 6b are performed, and after completion, when the operation lever 23 is pushed down, the handling cylinder upper cover 16 and the processing cylinder upper cover 1 are
5 is closed, and the hooks 27, 27 are weak springs 2
Pin 3 is rotated back by 8a and 28a.
1 and 31 and are locked in the closed state, and the operating lever 23 is locked with the latch 48.

In addition, grains and small straw waste generated in the handling room after threshing the grain culms leak through the receiving net 38 to the swinging sorter 37 and are screened and screened while being transferred. , long straw, cut ears, etc. enter the transfer chamber 6a of the processing section 6 through the dust inlet 3, and when they move to the processing chamber 6b, the processing cylinder 12 performs graining and fragmentation processing, and is transferred from the processing cylinder receiving net 13. The leaked waste joins the oscillating sorter 37 and is sorted, and the straw waste is discharged from the dust outlet 50 and the suction windmill 36 to the outside of the machine.

Furthermore, since the frame 32 has a U-shape when viewed from the side, the waste straw is sequentially moved toward the ear side by the waste straw transport device and then passes through the bent portion of the frame 32, so that the waste straw is easily transported. without becoming a hindrance,
And the long lower part facing forward covers the processing trunk upper cover 1.
6 can be firmly fixed.

(g) Effect of the invention As mentioned above, this invention has a processing chamber 6 on the side of the processing chamber 2.
In the threshing machine equipped with b, the handling trunk upper cover 16 of the handling chamber 2 is pivotally connected to the side opposite to the handling opening so that it can be opened and closed, and the processing trunk upper cover 15 of the processing chamber 6b is located at a lower position than the handling trunk upper cover 16. Attaches removably with
The processing cylinder upper cover 15 is attached to the processing cylinder upper cover 1.
6 by the frame 32, the processing cylinder upper cover 15 is connected to the processing cylinder upper cover 16 together with the processing cylinder upper cover 16 by the frame 32, even though it is separately engaged at a lower position on the side of the processing cylinder upper cover 16. Since it can be opened and closed, and the processing cylinder upper cover 15 rises significantly, maintenance and inspection of the narrow processing chamber can be easily carried out.
