Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is a versatile device that can feed all harvested crops into a handling chamber and can be used for harvesting and threshing not only rice and wheat but also beans and millet. This is related to an expensive ordinary type combine harvester.

Conventional technology A conventional combine harvester, which is installed at the front of the machine and feeds all of the grain harvested by a reaping section to a threshing section for processing, is disclosed in Japanese Patent Application Laid-Open No. 58-812, or Japanese Utility Model Application No. 58-to0
The one described in Publication No. 539 and the like is known.

Problems to be Solved by the Invention However, in conventional ordinary combine harvesters, when the next crop is wet material or there is a large amount of waste straw etc., all of the waste material is not supplied to the threshing section. Since it cannot be smoothly transferred and discharged to the rear of the machine, it has the disadvantage that it cannot be used universally for various crops such as beans and cereals, which have different working conditions.

The present invention was devised to solve these problems in view of the above-mentioned actual situation, and even if there is a large amount of waste straw generated in the handling room or if it is wet material, The threshing section of a conventional combine harvester can reliably transport and discharge lubricant to the rear of the handling room during the threshing process, and can be used for a wide variety of crops with different working conditions [provided by TK] It is intended to.

Means for Solving the Problems In order to achieve the above object, the technical means taken by the present invention is to supply the entire grain culm harvested by the reaping section at the front of the machine body into the handling room at the rear of the reaping section. In an ordinary store condominium in which the grains are threshed, a rotatable processing cylinder is installed in the handling room, and the nine grain culms are supplied to the starting end of the processing cylinder and are threshed while moving toward the terminal end. The present invention is characterized in that a dust exhaust fan is integrally formed at the terminal end of the processing cylinder to suction and discharge straw waste, etc. from the handling chamber. Function Next, the function of the present invention constructed as described above will be explained. If the entire amount of crops harvested by the reaping section installed at the front of the machine is fed into the handling chamber at the rear of the reaping section, the crops will be threshed by the rotatable processing cylinder installed in the handling chamber, and the crops will be harvested from the starting end of the processing cylinder. It is transported toward the terminal end, and the straw and other debris are discharged to the rear of the machine. The dust exhaust fan installed at the rear end of the processing cylinder rotates integrally with the processing cylinder to suck up straw, etc. from the handling chamber, so the nine crops that are supplied contain a lot of waste materials, especially leaves, stems, etc. Even in the case of wet material that is difficult to transport under crop conditions, the transporting action of the processing cylinder and the suction action of the dust removal fan work together to transport the waste material after threshing in all directions. It can be ejected beyond the machine body, and can be widely used for harvesting and threshing various crops with different working conditions, such as rice, wheat, beans, and millet.

Embodiment The configuration of the present invention will be explained with reference to the embodiment shown in the drawings. In Figures 1 and 2, 1 is the reaped part of the grain culm, 2
3 is a threshing section, 3 is a sorting section, the reaping section 1 is provided at the front of the machine body, the threshing section 2 is provided at the rear of the reaping section 1, and the sorting section 3 is provided below the threshing section 2. The above-mentioned reaping part 1, a grain culm scraping reel 4 in the front, and a cutting blade 5 in order from the bottom to the rear upper part.
, an auger 6, a conveyor 7, a grain culm supply reel 8, etc. A processing cylinder 11 is connected to the threshing section 2 in the longitudinal direction of the machine body via a shaft 10t mounted in the processing chamber 9.
is mounted on a shaft, and its front end is connected to the grain culm supply reel 8.
It is facing above. On the outer peripheral surface of the processing cylinder 11,
Handling teeth 12 and a conveying spiral body 13 are provided side by side, and the rotating processing cylinder 11 conveys the harvested grain culm toward the rear of the rack while threshing it. The conveying spiral body 13 is located at the rear end of the processing cylinder 11.
A dust exhaust fan 14 having a larger diameter is formed in one piece, and a dust exhaust chamber 15 that covers the dust exhaust fan 14 and is formed at the rear end of the handling chamber 9 has a dust exhaust fan 14 that extends downward. The dust exhaust port 16 is open. Reference numeral 17 denotes a grain leakage body stretched along the outer peripheral surface of the processing cylinder 11.

In the sorting section 3, a swinging shelf 19 on which chaff sieves 18 are arranged in multiple stages is installed below the leakage body 17 so as to be freely movable. The shaking action separates grains with a heavy specific gravity from straw waste with a light specific gravity. In addition, a main sorting winch 20 is provided on the front side of the sorting section 3, and an auxiliary fan 21 is provided on the rear side of the main sorting winch 20.
The sorting air generated at 0 passes through the chaff sieve 18 from below to above as shown by the arrow, floats straw waste, etc., and forms an air path that is sucked into the dust exhaust fan 714.
A part of the sorting air is directly discharged from the opening 22 at the rear of the fuselage as shown by arrow B.

Furthermore, an auxiliary exhaust port 23 is provided in the main sorting winnow 20,
Air is blown backward from the front end side of the leakage body 17, and the leakage body 1
It is designed to roughly sort out grains, straw waste, etc. that leak from the drain. 24 is a traveling section, 25 is a paddy tank, and 26 is a driver's seat.

In the above configuration, as the aircraft moves forward, the reel 4
Grain culms cut by the cutting blade 5 due to the raking action of
The entire quantity will be supplied within the period. Then, while the supplied grain culm is being threshed by the handling teeth 12 of the rotating processing cylinder 11,
It is transported toward the rear of the handling room 9 by the transport spiral body 13,
At this time, the threshed grains, straw waste, etc. leak downward through the mesh of the leakage body 17. And the rotating processing cylinder 1
At the rear end of 1, there is a dust removal fan 1 having a diameter larger than that of the conveying spiral body 13.
4 is integrally formed, the processed material transported by the transport spiral body 13 is further strongly suctioned by the dust removal fan 14, and especially multiple waste materials are removed from the grain stalks supplied into the handling chamber 9. Even in the case of wet material that is generated or difficult to be transported, the transport spiral body 13 and the dust removal fan 14 work together to reliably carry it into the dust removal chamber 15 and discharge it out of the machine from the dust removal port 16. Moreover, since straw waste etc. are also sucked from the front end side of the processing cylinder 11, there is less blowing out of straw waste etc. from the handling chamber 9.
Able to work hygienically.

Further, as for leakage from the leakage body 17, by the back-and-forth rocking motion of the rocking shelf 19, straw waste with a low specific gravity floats to the upper layer, and grains with a high specific gravity settle in the lower layer and are sorted out. At this time, the sorting air from the main sorting winnower 20 passes through the chaff sieve 18 and floats straw waste, etc., which are sucked by the dust exhaust fan 714, so that the sorting efficiency of the swinging shelf 19 can be significantly improved.

Furthermore, since the sorting air from the auxiliary exhaust port 23 provided in the main sorting winnower 20 is ventilated along the lower surface of the first lower body 17, rough sorting is performed in advance before leakage material falls onto the chaff sieve 18. , the sorting effect ``4'' can be further improved.

Effects of the Invention In short, this is the threshing section of the present invention! In a normal type container in which the grain culms harvested by the reaping section at the front of the body are fed in their entirety into the handling chamber at the rear of the reaping section for threshing, the handling chamber is equipped with a rotatable shaft. A processing cylinder is provided, and the grain culm supplied to the starting end of the processing cylinder is threshed and transported toward the terminal end, and a dust exhaust fan is integrally formed at the terminal end of the processing cylinder. Since it is configured to suction and discharge straw waste from the handling chamber, the conveying action of the processing cylinder and the suction action of the dust exhaust fan work together, even though all of the harvested grain culms are threshed within the handling room. Since all of the waste straw in the handling chamber is suctioned and conveyed to the terminal end of the processing cylinder, even if the amount of waste straw generated in the handling room is large or the supplied grain culms are wet material, the handling is easy. It can be reliably discharged from the end of the processing cylinder without clogging the room, and can be widely used for harvesting and threshing various crops with different working conditions, such as rice and wheat, as well as beans and millet. etc.), it has a whole range of new and useful effects.
