Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for switching and returning the terminal end of a grain culm conveying device in a combine harvester. The grain culms are separated, the hanging tips are pulled straight up using a pulling device, the roots are cut in this state, the cut grain culms are collected by a collection device, and the roots of the bundled grain culms are held by a root conveying device. The tip portion is transported by a tip conveying device, and the threshing process is carried out by the husk feeding device of the automatic feeding type threshing device provided at the rear.

In this edition, the problem is the tip guide of the tip conveyor, and in order to make it easier to transfer to the supply port of the threshing device,
If the tip of the ear guide is brought close to the supply port of the threshing device, the handover will certainly be better, but
It becomes impossible to supply shoddy shell culms from there. That is, during reaping work, the grain culms in the corners of the field that cannot be cut by the combine harvester are manually harvested with a sickle, so the hand-harvested husks must be thrown directly into the feed of the combine harvester.

However, if a combine harvester is equipped with a tip guide as described above, it will not be possible to input the hand-cut husk from there, making the work tedious.

Therefore, in the present invention, when installing the tip guide,
A switching guide body is attached to the tip of the guide, so that when switched to one side, smooth automatic harvesting can be performed, and when switched to the other side, hand-cut culms can be supplied. When power is transmitted to the reaping section in a state in which cut culm can be supplied, the ear tip guide automatically changes to the automatic reaping position. Automatic feeding type threshing device equipped with a reaping section consisting of a weed splitting device, pulling device, concentrating device, cutting blade, etc., and a culm supply device consisting of a culm supply/cheno and a culm trapping body behind the reaping section. A root conveying device and a ear conveying device [a] are provided between the reaping section, the automatic feeding type threshing device, and the supply port, and the ear conveying device is provided with a predetermined interval between the chain and the chain. It is formed by an ear tip transfer lug and an ear tip guide, which are attached to the tip, and the terminal end of the ear tip guide has a position where the grain culm conveyed (by the transfer lug) is smoothly fed into the supply port of the threshing device. A switching guide body is pivotally attached to the switching guide body, which can be rotated upward to switch freely between a position in which hand-handled grain culms can be introduced, and the switching guide body can switch this to a position in which hand-handled grain culms can be introduced. When power is transmitted to the reaping section,
The switching and return device for the terminal end of a husk culm conveying device in a combine harvester is configured so as to automatically return to a position for supplying husk culms to a threshing device supply port.

To explain the example diagrams, only the main parts are shown,
Traveling device, weeding device, pulling device, etc.
The cutting blade, focusing device, etc. are not shown. (11 is a threshing device, and a shell culm trap body (2) is attached to the upper side of the threshing device.

(3) is a shell culm supply chain attached to the lower part of the shell culm supply chain, and the clamping body (21) and the supply chain (3) form a shell culm supply device (4). Torso chamber, (

There are numerous handling crystals planted on the outer circumferential surface of the handling cylinder (6), (
Reference numeral 8) denotes a supply port through which the tip portion of the grain culm, with the nine parts of the stock held therein, is inserted into the handling barrel chamber (5) by the culm supply device (4)K. The front side of the supply port (8) (in the case of a combine, the forward side of the machine is the front side, and the opposite side is the rear side) K is the front side of the supply port (8).
) is installed. 0 [is an endless ceno for transporting the root of the grain culm whose root has been cut by the cutting blade of the reaping section;
(1υ is a trapezoid that is paired with the endless Cheno 0,
The chain frame and the clamping body Qll form a base conveying device O3.

The terminal end of the conveying device (12) is close to the starting end of the shell culm feeding device (4) of the threshing device +I+, and takes over the root portion of the grain culm. 04 is a transfer lug thereof, and Q51 is a transfer lug α-brown, which is a tip guide that guides the tip portion to be transferred.

However, the Ragmira is wrapped around a cheno (1υ
are provided at predetermined intervals, and the lugs Q, I
The shape of l is approximately ]-shaped, and there is a turning part 'l? ), it spins around and turns, and on the other side it folds and turns.

However, the switching guide body Ql is attached to the tip of the tip guide a9 by an axial tilt, and the switching guide body oI
The tip faces the vicinity of the supply port (8) of the threshing device +11. The switching guide body 0! J is constantly fixed in one position by the action of the spring (A). When the switching guide body 0 is in the state shown in FIG. 2, it performs a normal threshing action, but when it is manually changed to the state shown in FIG. (8) Yo□
1. As it moves away, it becomes a state where it is supplied with hand-cut husk culms. However, in this state, if power is transmitted to the reaping section and the lugs (141, etc.) move, a pin C11 is provided that will collide with the lug and return the guide body 09.

Next, we will discuss the effect.

In the above-mentioned embodiment, for example, when a manual lever for switching is separately provided, when the lever is manually moved to the ON position, a known clutch mechanism is engaged and the reaping section starts operating. At the same time, the wire connected to the switching lever is loosened, so the switching guide body a9 becomes the state shown in FIG.
close to the supply port (8). If a manual lever is not provided, holding the switching guide body 0 directly by hand and rotating it downward will result in the state □ shown in Fig. 2. Therefore, the grain culm harvested by the reaping section As shown in FIG. As a result, the grain is supplied from the supply port (8) into the handling barrel chamber (5) and threshed.

However, since combine harvesters cannot make small turns, the corners of the field are left uncut, which must be harvested by hand with a sickle, etc., but the hand-harvested grain culms are directly harvested from the feed port (8).
It will be thrown into. In that case, turn the manual lever to O.
When set to the FF position, the switching guide body 01 is lifted up by the wire as shown in Figure 3 and the supply port (8) is wide open, so all you have to do is throw the hand-cut culm into the supply port (8). . Then, the clutch is engaged again to move the reaping section to reap and thresh. In that case, manually return the body tilt of the switching guide from the state shown in Fig. 3 to the state shown in Fig. 2, but even if you forget to do so, you can continue the work as shown in Fig. 4. When lug I hits pin (2υ),
The switching guide body (2) is automatically brought into the state shown in FIG.

The present mastication is as described above, and in particular, a reaping section consisting of a weed splitting device, a pulling device, a converging device, a cutting blade, etc. is provided in front of the traveling device, and a grain culm supply chain (3) is installed behind the reaping section. ) and a grain culm feeder (4) consisting of a culm trap (2); 8), a root conveying device 0'3 and a tip conveying device Oj are provided between the tip conveying device 0'3 and a tip conveying device 0'5. It is formed by a tip guide (151), and the tip guide a!
At the end of 19, there is a position where the grain culm conveyed by the transfer lug is smoothly fed into the supply port (8) of the threshing device (1), and a position where the grain culm is rotated upward to input the cut grain culm. A switching guide body OI that can be freely opened and switched between a position where it can be opened and moved is pivoted, and the switching guide body α9 is 1, and when it is switched to the cutting shell culm insertion position, when power is transmitted to the reaping part. Since the switching guide body 01 is configured as a switching and returning device for the terminal end of the grain conveying device in the comparator so that the threshing device (11) automatically returns to the position of supplying the grain culm to the supply port (8). Since it returns automatically, it is effective in preventing clogging of the culm.
