Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is intended to eliminate the delay of the tip portion of the grain culm transporting device for transporting the grain culm after cutting by the cutting blade to the threshing device in the combine harvester. In addition, the present invention relates to a tip wheel conveying star wheel device further arranged on the upper conveying device.

(B) Conventional Technology Conventionally, a technology related to a combine transport device has been known. For example, it is as disclosed in JP-B-59-8501, JP-B-56-71125, JP-A-58-111608, and JP-A-54-101126.

Further, in a combine grain culm transporting device, a technique in which another tip transporting device is arranged on the upper transporting device is known in order to eliminate a delay in transporting the ears that occurs during soft long culm.

For example, JP-A-61-202623 and JP-A-61-216614
As in Japanese Patent Publication No. 56-75839.

In addition, as a prior application of the same applicant, 1 above the upper conveyance device.
A technology for arranging a stepped tip conveying star wheel device is also applied.

(C) Problems to be Solved by the Invention However, in the prior art of the prior application, as shown in FIG. 4, a tip conveying star wheel device including a one-stage star wheel is provided above the upper conveying device. However, since the star wheel has one step, it cannot convey the effect to all the tips of the grain culms with uneven culm length, and it bends under the star wheel, and the culm is removed. There was also a tip part that passed through while generating an action. And, the grain culm which did not receive the carrying force by these star wheels caused culm drop or cutting of the ears.

According to the present invention, a multi-stage tip conveying star wheel device is arranged so as to uniformly exert a conveying action on the tip of the long culm protruding largely above the upper conveying device.

(D) Means for Solving the Problems The object of the present invention is as described above, and the configuration for achieving the object will be described below.

In a combine grain culm transporting device, a chain type stock yuan transporting device 4 is arranged below, and a tine type upper transporting device 2 is arranged thereon, and a star wheel is driven from a rear upper surface of the upper transporting device 2. A multistage star wheel 1a, 1b, 1c in which the shaft 1d is projected, and the tip conveying star wheel device 1 is provided on the star wheel driving shaft 1d, and the tip conveying star wheel device 1 is fixed on the star wheel driving shaft 1d.
It was ...

(E) Embodiment The purpose and construction of the present invention are as described above. Next, the construction of the embodiment shown in the accompanying drawings will be described.

FIG. 1 is a side view of the grain culm conveying device of the present invention, FIG. 2 is a front view of the same, FIG. 3 is a perspective view of a multi-staged star wheel, and FIG. FIG. 5 is a perspective view of an embodiment configured to have a small diameter, FIG. 5 is a side view of the same embodiment of FIG. 4, FIG. 6 is a side view of a structure in which a star wheel is slidable up and down, and FIG. It is a side view of a culm conveyance device.

The overall structure will be described with reference to FIGS. 1 and 2.

A weed board 10 is arranged at the front end of the grain culm conveying device. The culm culled by the swarding plate 10 is raised by the raising device 8.

While raising the lodging grain culm by the raising device 8L, 8C, 8R, the stock root part is scraped by the tine device 3L, 3C, 3R, and the central part of the grain culm is held by the upper transfer device 2L, 2R. .

Furthermore, the scraping wheels 9L, 9C, 9R are rotated at the terminal positions of the scraping tine devices 3L, 3C, 3R, and the scrap stock part of the scraped grain stem is inherited by the stock carrier devices 4L, 4R. .

Further, the lower part of the stock root portion is cut by the cutting blade 15 while scraping by the scraping tine devices 3L, 3C, 3R.

With the stock base of the grain culvert being sandwiched by the stock carrier 4 and the central part being held by the upper carrier 2L, 2R, the stock
It is inherited by the vertical transport device 6 while receiving an auxiliary transport action by the auxiliary stock source transport device 5 arranged on the stock source transport device 4.

The central part of the grain culm held by the upper transfer devices 2L, 2R is inherited by the upper transfer rear part 7, the tip part is transferred to the handling chamber of the threshing device, and the root part is transferred to the feed chain.

In the case of soft long culm rice, as shown in Fig. 7, the tip portion is located higher than the upper conveying devices 2L and 2R, so that conveyance delay occurs and the star wheel is composed of only one stage. In this case, the tip was bent and was conveyed under the star wheel in a bent state, and it was caught or culled.

In the present invention, in order to eliminate such a problem, the tip conveying star wheel devices 1L and 1R capable of holding the tip of the long culm are arranged above the upper conveying device 2.

As for the disposition of the tip conveying device 1, when viewed from the top and bottom in a side view, it is located above the upper conveying device 2, and the rear end thereof is arranged near the front end position of the upper conveying rear part 7.

In FIG. 2, the configuration of the auxiliary stock carrier 5 and the stock carrier 4L, 4R below the scraping tine devices 3L, 3C, 3R is omitted.

Further, in the present invention, as shown in FIG. 2, a pair of left and right tip conveying star wheel devices are provided at the rear end positions of the upper surfaces of the upper conveying devices 2L, 2R arranged on the left and right in a plan view.
1L and 1R are arranged.

However, it is a matter of course that the number of the tip conveying star wheel devices 1 may be increased when the number of cutting lines increases.

Further, as the drive structure of the multistage star wheel, the sprocket shafts of the upper transfer devices 2L and 2R are extended upward,
Star wheel drive shaft 1d, and the star wheel drive shaft
A plurality of star wheels 1a, 1b, 1c ... Are fixedly mounted on 1d and are rotated at the same rotation speed.

The star wheels 1a, 1b, 1c have a star-shaped projection because the star wheels 1a, 1b, 1c need to have the function of engaging and transporting the grain culms.

The star wheels 1a, 1b, 1c shown in FIGS. 4 and 5 may have the same rotation diameter as the star wheels 1a, 1b, 1c of a plurality of stages as shown in FIG. As you can see, the star wheel 1 has a diameter that gradually decreases from the bottom.
It may be a, 1b, 1c.

Moreover, in order to obtain the same effect as having the multi-staged star wheels 1a, 1b, 1c, one star wheel 1e is configured to be slidable above and below the star wheel drive shaft 1d so that it can be placed at the tip of the long culm. Correspondingly, the star wheel 1e may be adjusted up and down.

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

Firstly, by disposing the tip conveying star wheel devices 1L, 1R composed of multi-stage star wheels 1a, 1b, 1c ... above the upper conveying device 2, in the conventional case of soft long culm. , The raising device 8 to the upper transport rear part 7
There is nothing to hold up to the time, and the breakage of the spikes, dropouts, and cuts occurred in the middle, from the time when the raising device 8 releases the holding state to the time when it is passed to the upper conveyance rear part 7. , Once the star wheels 1a, 1b, 1c apply a carrying force to hold the tip portion, it is possible to smoothly carry even in the case of soft long culm rice.

Secondly, since the tip conveying star wheel device 1 is composed of multi-stage star wheels 1a, 1b, 1c ..., the multi-stage star wheels 1a, 1b, 1c act up to the upper part of the soft culm. , The grain culms are no longer clogged or shredded.
