BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an anti-winding device in a scraping transfer device for transferring grain stalks from a combine raising device to a feed chain.

[0002]

2. Description of the Related Art Conventionally, in a stocking-type scraping device of a combine, a driven-side scraping wheel does not have a transport chain, and is configured to rotate in accordance with the rotation of a driving-side scraping wheel. When culms, weeds, and the like were scraped, wrapping was likely to occur. Therefore, the winding prevention collar was provided on the shaft. For example, Shokai 61-5
6837.

[0003]

However, the anti-winding collar provided on the shaft of the scraping wheel of the conventional stock scraping device is configured to rotate with the rotation of the scraping wheel.
This increased the wrapping, which hindered the rotation of the scraping foil and caused clogging.

[0004]

The problem to be solved by the present invention is as described above. Next, as a means for solving the problem, a lower conveyer of a combine is provided around a rotating shaft of a driven scraping wheel. Is provided with a winding prevention collar, a notch is provided in the winding prevention collar, a bracket arm is inserted into the notch to prevent rotation, and a metal receiver supporting a rotating shaft is fixed to the bracket arm end. It was done.

[0005]

With the above construction, when the grain stem reaches the combine scraping device of the combine, the stem of the grain stem is clamped by the adjacent driven-side scraping wheel and the driving-side scraping wheel, and is transferred to the lower transport chain. At this time, a winding prevention collar is externally fitted to the rotation shaft of the driven-side scraping wheel, and the winding prevention collar cannot be rotated because the bracket arm is inserted through the notch, and There is almost no wrapping of culms and weeds around the driven scraping wheel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved and means to be solved of the present invention are as described above. Next, the specific structure of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front perspective view of a combine, FIG. Is a rear perspective view of the combine, FIG. 3 is a perspective view of the anti-winding collar of the present invention, FIG. 4 is a side view of the feed chain guide, FIG. 5 is a plan view of the same, FIG. 7 is an enlarged side view of a link connecting portion of an embodiment using a coil spring, FIG. 8 is a side sectional view of a conventional Glen tank, FIG. 9 is a side sectional view of a rotating Glen tank, and FIG. 1 is a perspective view of a Glen tank in which the apparatus is installed, FIG. 11 is a partial plan view of an equalizer mechanism, and FIG.
2 is a partial side view of the equalizer mechanism, FIG. 13 is a partial side view of the lower transport device, and FIG. 14 is a front view of the same.

In FIG. 1 and FIG. 2, a combine is provided with a machine frame fixed on a crawler-type traveling device D, a raising / cutting device B at a front end, a cabin 30 at a rear portion thereof, and a threshing device / sorting device at a side portion thereof. A Glen tank C is provided at the rear of the cabin 30.

The crawler-type traveling device D has conventionally had a problem to secure the front-rear and left-right balance. Among them, securing the front-rear balance includes loading and unloading on trucks, crossing ridges, and the like. It is particularly necessary to perform the above operation smoothly, and it has been coped with by adopting the equalizer mechanism in the wheel portion, but it was not sufficient. Therefore, as shown in FIGS. 11 and 12, the equalizer 24 of the combine crawler type traveling device D is connected to the piston rod of the hydraulic cylinder 25 so that the equalizer 24 can be moved back and forth, and the combine is loaded or unloaded on the truck. At the time of lowering or crossing the ridge, the hydraulic cylinder 25 is operated and slid by moving the equalizer 24 and the convex part of the boundary between the truck bed and the bridge or the convex part of the ridge and the movement of the convex part. This allows the combine to run smoothly without any severe shock.

Further, if the size of the combine is increased in order to increase the efficiency of the work, the driver's seat becomes a cabin as shown in FIG. In this case,
At the time of work, there was a problem that the visibility behind was deteriorated. Therefore, a distance sensor 26 is installed at the rear of the combine to sense the distance between the combine and an obstacle behind, and the distance sensor 26 is connected to an actuator such as a hydraulic cylinder via a control circuit, so that the actuator is driven by the main transmission. Connected to the lever, the speed of the combine gradually decelerates as the vehicle approaches the obstacle behind the vehicle when moving backwards, and stops when the set distance is reached. is there.

[0010] The raising and cutting device B raises the raised culm by the tine and cuts it with a cutting blade, and the cut culm is conveyed to the feed chain 7 by the conveying device. The transfer device comprises an upper transfer device, a lower transfer device A, and a vertical transfer device, and the lower transfer device A is provided with a winding prevention collar which is a main part of the present invention. That is, as shown in FIG. 3, FIG. 13 and FIG.
A lower transport device A is disposed above the cutting frame 32 below the tine case 31. The lower transport device A includes transport chains 34 and 35, and a drive-side scraping wheel that is rotated by the transport chains 34 and 35. 36, a driven scraping wheel 39, 39 driven by meshing with the rotation of the driving scraping wheel 36, 36;
36 and a tine-equipped conveyor belt 40 and the like which are turned together with the rotation of the driven-side scraping wheels 39. Since the driven-side scraping wheel 39 does not have a chain wound thereon, it is inevitably grass or grain culm. It was easy to wind around.

Therefore, the present invention is intended to prevent the winding by preventing the winding prevention collar 2 fitted on the rotating shaft 37 of the driven side scraping wheel 39 from rotating. That is, the bracket arm 3 is laterally provided at the rear of the mounting frame 33 extending upward from the mowing frame 32, the metal receivers 4 and 4 are fixedly provided at both ends of the bracket arm 3, and the rotating shaft 37 is attached to the metal receiver 4. A drive pulley 41 is fixedly mounted on the upper end of the rotating shaft 37, and the driven side scraping wheel 39 is fixed to the lower end.
Is fixed. The winding prevention collar 2 is provided on the outer periphery of the rotating shaft 37 between the driving pulley 41 and the driven side scraping wheel 39. The winding prevention collar 2 is provided with a notch 2a. The bracket arm 3 is inserted through the portion 2a to prevent the winding prevention collar 2 from rotating.

And an upper transport device, a lower transport device A,
The grain stalks cut by the vertical transport device are sent to the feed chain 7 and threshed. The feed chain 7 is provided with a feed chain guide 8 as shown in FIGS. 8, the ears are threshed by pinching.

Since the feed chain guide has conventionally been integrally formed in a "F" shape, there has been a problem that the culm becomes difficult to enter between the feed chain and the feed chain guide rod during handling. The feed chain guide 8 is divided into a front feed chain guide 9 and a rear feed chain guide 10, and links 11 and 12 are fixedly provided at the rear end and the front end of the two.
・ Pin 12 is connected with pin 13 and tension spring 14
Are provided, and stoppers 16a and 16b are provided at the pivotal portion so as not to be broken. However, tension spring 1
It is also possible to use a coil spring instead of 4.

With such a configuration, the feed chain guide 8 is in a state of being attached to the feed chain 7, and when the grain culm is inherited from the cutting section to the feed chain 7, the culm is suppressed and the culm spill is eliminated. Also, even when a large amount of culm is sent, the culm pushes up the links 11 and 12 of the feed chain guide 8 to create a gap between the feed chain 7 and the feed chain guide 8 so that the culm can be smoothly fed into the threshing inside. Will be
Further, even during manual handling, the culms can be inserted smoothly because the links 11 and 12 of the feed chain guide 8 are maintained by the force of the tension spring 14.

The grains thus threshed are sorted and fine grains are stored in the Glen tank C. In the Glen tank, as shown in FIG. 8, the slanted plate 17 has an inclined space so that the sludge plate 17 is inclined so that the paddy falls smoothly. In this embodiment, as shown in FIG. 9, the lower conveyor 18 of the Glen tank C is installed near one side plate 19, and the lower conveyor 18
When the lower tank 18 is driven to discharge the grains in the Glen tank C, the grain is gradually reduced and a bridge is formed to reach the lower conveyor 18. The grain sensor 20 is provided at a position where it disappears, more specifically, slightly above the intersection of the flow tray 17 and the rear plate 15 in FIG. Is operated, and the Glen tank C is configured to rotate about the lower conveyor 18 as a fulcrum. This makes it possible to effectively use the wasted space of the conventional hatched portion and increase the size of the Glen tank. However, it was no longer necessary to extend the width of the combine.

The amount of paddy in the Glen tank C could be checked by the driver on the monitor, but it could not be checked by a person other than the driver from a distance. Therefore, as shown in FIG. A lighting fixture 22 is mounted inside C, and a plurality of glass (may be a lens or the like) 23,... Which can be seen vertically in the side plate are arranged on the side plate. The lights are sequentially turned off, so that a person other than the driver can easily check from a distance. Then, it was possible to confirm the quality of the sorting of paddy from outside through the glass.

[0017]

[Effects of the Invention] The present invention is constructed as described above, and has the following effects. That is, since the winding prevention collar is stopped in the rotation direction in a free state, the winding is not increased, and there is no need for a special member for fixing the collar, so that there is naturally no catch portion. The wrapping is largely eliminated.
