Description

[Detailed Description of the Invention] Generally, a conveyance chain is deformed by the vibrations of the machine body and conveyance resistance and cannot perform reliable conveyance, so a chain guide is often provided.

However, when transporting grain culms, the grain culms have a large amount of straw waste at the base of the stock, as well as weeds and soil attached, which accumulate in the chain guide and cause clogging.

The present invention aims to provide a grain culm conveying device that can accurately hold and guide a grain culm conveying chain, does not become clogged with straw, weeds, soil, etc., and has good maintainability. In a grain culm transport device in which a grain culm transport chain is suspended such that its link pins are vertically oriented, inverted L-shaped chain guides are provided on both sides of the grain culm transport chain, and these chain guides are The upper bent part is brought close to the chain roller, a spacer is interposed between the hanging parts of the pair of chain guides to regulate the guide gap, and the spacer and the hanging parts of the pair of chain guides are attached to the machine frame. It is characterized in that it is attached by being fastened together with bolts.

The embodiment shown in the drawings will be explained below.1
is a binder machine frame, and has a pair of grain culm raising bodies 3, 3 having grass cutting bodies 2, 2 on both sides of the front part, a cutting blade 4 is attached below them, and a cutting blade 4 is attached in the middle part. A pair of left and right wheels 5, 5 are pivotally supported, and a handle 6 and an engine 7 are provided at the rear.

Further, above the rear portion of the cutting blade 4, a lateral conveyance chain 8, a conveyance belt with lugs 9, 9, and an upper guide plate 10 are provided in order from the bottom.

A mounting plate 13, a bearing 1
4 and a vertical shaft 15, and the link pins of the horizontal conveyance chain 8 protrude upward at intervals slightly larger than the spacing between the tips of the claws of the star foil 16. , the star foil 16 is deeply overlapped on the transverse conveyance chain 8 so that before the leading claw leaves the protruding link pin 17, the next claw enters into the movement locus of the link pin.

In addition, the star foil 16 of the horizontal conveyance chain 8
The portion facing the chain roller is guided and regulated by a pair of front and rear inverted L-shaped chain guides 18, 18 that slide into contact with the chain roller.
The hanging part of the chain guide plate 19 is fixed to the support frame 20 together with the lower guide plate 19 by bolts 22a and nuts 22b with the spacing regulated by a cylindrical spacer 21. If the dimensions of the horizontal conveyance chain 8 are different, replace it with a slightly shorter spacer 21, insert a washer 23 and replace it with a thinner one, or remove it.

Furthermore, the protruding link pin 17 of the horizontal conveyance chain 8
A lug 24 that forms a grain culm holding space between the lug and the claw is attached to the rear link pin.

Reference numeral 25 denotes a pair of upper and lower fixed guides whose front portions are attached to the support rods 12 of the intermediate weeding body 11. The upper side surrounds the center of the star foil 16, and the lower side projects out of the rotation trajectory of the star foil 16. Flexible guides 26, 26 made of spring steel are provided at the end of the portion facing the horizontal conveyance chain 8, respectively, protruding so as to intersect the cutting blade 4 at a small angle. A flexible guide 27 whose front end is fixed to the front part of the guide 25 has its rear end aligned with the rear part of a scraper 28 provided on the side of the cutting blade 4.

Further, a flexible guide plate 29 whose rear end is close to the upper and lower surfaces of the star foil 16 is attached to the right side weeding support rod of the intermediate weeding body 11.

Reference numeral 30 denotes a binding device provided on the side of the cutting blade 4, which is driven by a chain 31 and is connected to the scraping body 2.
A fixed guide 25a is attached to the inside of 8.

In the above-mentioned device, the stock base of the grain culm raised by the grain culm pulling bodies 3, 3 is connected to the fixed guides 25, 25a.
It is guided toward the cutting blade 4 while being collected by the flexible guides 29 and 27, and is raked into the cutting blade 4 by the star foil 16 and the raking body 28 to be harvested.

The harvested grain culm rests on the upper guide plate 10, and the stock part of the grain culm that entered between the fixed guide 25 and the flexible guide 29 is transferred to the horizontal conveyance chain 8, this lug 24, and the star foil 16. is conveyed toward the binding device 30 while being held between the front and rear claws of the
The stems are transported by conveyor belts 9,9.

At that time, the front claw a is connected to one protruding link pin 1.
7, the star wheel 16 rotates, and just before the pawl a separates from the protruding link pin 17, the next pawl b engages the next protruding link pin 17 as shown in FIGS. Forcibly invade the front.

Also, on the one hand, the grain culms scraped by the claws and the lugs 24 push the flexible guide 26 forward, and on the other hand, the flexible guide 27 is pushed out to the right in FIG. Since they contact the tip of the grain culm and form a series and restrict each other, it is possible to prevent the stock base of the grain culm from being pushed out between the fixed guide 25 and the flexible guide 27 on the lower side thereof and falling out. .

The grain culms that have been transversely fed in this manner and the grain culms that have entered from the lower side and merged are fed into the collecting culm part 30a of the bundling device 30 by the scraping body 28 and the packer 32, and are bundled and released.

Incidentally, instead of the protruding link pin 17, as shown in FIG.
3 protrudes forward and a locking pin 34 is provided protrudingly on this link plate 33, the distance between the horizontal conveyance chain 8 and the star foil 16 can be increased, and the grain culm clamping space can be widened.

During the grain culm transportation described above, straw, weeds, soil, etc. that fell between the chain guides 18, 18 fall downward.

As mentioned above, the present invention is a grain transporting device in which a grain culm transport chain is suspended such that its link pins are vertically oriented, and inverted L-shaped chain guides are provided on both sides of the grain culm transport chain. The upper bent part of the chain guide is brought close to the chain roller, and a spacer is interposed between the hanging parts of the pair of chain guides to regulate the guide gap, and the spacer and the hanging parts of the pair of chain guides are interposed. Since it is attached to the machine frame by bolting together, it is possible to accurately guide the grain culm conveying chain while holding both sides with the chain guides, but there is no possibility that straw, weeds, mud, etc. Even if the grain falls into the ground, it will not get stuck between them and will fall below it, allowing for nimble transportation of the grain at all times.

Moreover, since the chain guide can be easily assembled and disassembled, maintenance and inspection can be easily performed.
