Description

[Detailed Description of the Invention] The disclosed technique belongs to a technique of intermittently discharging the discharge associated with the bundled discharge of the binder tip conveyance.

Therefore, this invention relates to a discharging device in which the auxiliary conveyance section is provided above the binding section to carry out the tip conveyance accompanying the lateral conveyance of the binder after lifting the grain culm and reaping. The wheel is coaxially integrated with the terminal pulley of the ear tip conveying rubber belt so that it constantly rotates, and the opening/closing cover plate for the star wheel is returned to the frame and pivoted to a separate shaft with a spring attached to allow intermittent rotation of the tying machine. This invention relates to a binder discharging device in which an opening cam lever linked to a discharging arm is integrally provided on the opening/closing cover plate.

As is well known, the binder used in the reaping and harvesting machine is harvested after the lifting operation, tied by a tying machine by being conveyed horizontally at the base of the plant, and discharged by a discharge arm, and the tips are also conveyed horizontally by the conveying of the tip. However, in recent years, there has been an increase in the number of types of bundling machines in which a bundling device is attached as an attachment to the bundle discharge section.

However, in the conventional type, the auxiliary conveyor belt extends to the side for a very long time and is used for ejection force, making it difficult to perform intermediate splitting operations. It had some annoying flaws.

In order to solve this problem, it has been proposed to make the auxiliary conveyance protrusion foldable, but the structure is complicated and difficult to operate, and depending on the design, there are problems that may hinder discharge.

The purpose of this invention is to take into account the problem of auxiliary conveyance of binder based on the above-mentioned conventional technology, and to provide a companion rotating star wheel at the rear end of the tip conveyance, and to link the opening/closing cover plate for the star wheel with the discharging arm so that the tip can be removed only during discharging. It is an object of the present invention to provide an excellent binder discharging device based on a simple structure and rational design that enables transport and discharging.

The structure of this invention, which meets the above objectives, is that while the harvested grain stalks are being pushed into the revolving door by the packer, the cover plate at the end of the grain conveyance covers the star wheel and auxiliary conveyance is not performed. The gist of this invention is that when the discharge arm discharges the bundles after tying, the discharge arm opens the cover plate via a cam lever, and the tips are also conveyed and discharged by the rotating star wheel.

Next, one embodiment of this invention will be described below based on the drawings.

1 is a binder, an engine 3 and a tank 4 are attached to the rear of the frame 2, and a wet field transmission case 6 equipped with dry field tires 5 and a wet field transmission case 8 equipped with zero pressure wet field tires 7 are installed in the center part. They are designed to be selectively assembled into forward and intermediately inclined positions using keyways 9 and 9', respectively.

In addition, a lifting device 10 is installed obliquely in the front part, and a cutting blade 11 is installed at an angle.
A stock transfer chain 12 is installed in the middle, and a well-known bundling machine 13 equipped with a discharge arm/revolving door 14, a timing gear 15, a building 16, etc. is installed at the side, and furthermore, at the bundling position. An attachment type focusing device 17 is removably provided.

A lug-equipped ear tip conveying belt 20 is stretched between the base driving pulley 21 and the outer end driven pulley 22 in the slit 19 of the upper oblique conveying plate 18, so as to be constantly rotated together with the binding machine 13. ing.

Further, an auxiliary conveyance star wheel 24 is fixed to the upper end of the shaft 23 of the driven pulley 22 so as to be rotated together with the tip conveyor belt 20.

A cover plate 25 is formed to cover at least the drive side of the star wheel 24 with a gap in between, and is fixed to a pin 26 loosely supported on the frame 2. At 26, a bow-shaped cam lever 27 is engaged with the revolving door 14, and is regulated by a stopper pin 28 provided on the frame 2, and a return spring 29 is stretched between the cam lever 27 and the frame 2.

In addition, 30 is a grain culm.

In the above configuration, in advance, binder 1 is
Tires 5, 7 and transmission case 6 for wet fields.
8 is selectively assembled, exposed to the field, and used for cutting and tying.

Then, the grain culm 30 raised by the raising device 10 is cut by the cutting blade 11, the stalk is transported laterally by the grain chain 12, and is pushed into the stop revolving door 14 in FIG. The tip is sent to the tip by the tip conveyor belt 20, and is covered by the cover plate 25 by the return spring 29 against the star wheel 24 at the top of the revolving door, so it is not sent out and stops, and both the stock base and the tip are packed together. The grain culm 30 is stopped at a predetermined timing, and the grain culm 30 is bound by a needle, a bill, and a bill holder (not shown), and through the action of a timing gear 15, the rotary door 14 is intermittently rotated by 180 degrees and a half at a predetermined timing as a discharge arm, and the bundled grain culm 30 is moved to a concentrator 17. released into the

In this process, when the revolving door 14 rotates half a turn as shown in FIG. Thereby, the cover plate 25 is also integrally moved outward by ΔL, and the star wheel 24 is exposed and brought into direct engagement with the grain culm 30, so that the ears are immediately conveyed and released by inertial force.

In this case, since the outer diameter of the star wheel 24 is larger than the diameter of the pulley 22, the discharge speed is higher than the tip conveyance, and the discharge speed of the revolving door 14 can be made smaller, and the discharge speed is discharged to the speed collection device 17 as designed. do.

Then, when the revolving door 14 rotates 180 degrees and the cam lever 27 is returned by the return spring 29, the cover plate 25 again covers the drive side of the star wheel 24, preventing its rotation from engaging the tip and contributing to the next bundling. Ru.

It goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment, and various embodiments can be adopted, such as making the cover plate bow-shaped so as to cover only the drive side of the star wheel. .

As described above, according to this invention, in the binder discharging device, a star wheel is provided at the end of the tip conveying belt, and a cover plate having a cam lever is opened and closed at least on the driving side of the star wheel. By making the cam lever engageable with the ejection arm, the auxiliary transport is basically extremely short, which has excellent effects such as making it easier to perform the middle-splitting work and making it easier to attach and detach the focusing device. In addition, there is no need for folding for auxiliary transport, and the aircraft body can be made more compact and compact.

Furthermore, since the cover plate opens the star wheel only when the release arm rotates via the cam lever, the tips of the ears also stop when tying and are transported and released only when being released, so the grain culms are always vertical from the base of the plant to the tips of the ears. Since the posture can be maintained, it is also effective in making it easier to eject and bundle bundles.
