Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a combine harvester.

(Prior art) A conventional combine harvester has a threshing device, cutter,
A bagging device and prime mover are installed, and a reaping device is attached to the front of the traveling platform.

(Problems to be Solved by the Invention) The combine harvester described above has a large overall structure due to the traveling platform, and has not been miniaturized.

Therefore, if a crawler is attached directly to the threshing machine itself, which is made of thin iron plates, and various accessories are directly attached to the threshing machine, the frame of the threshing machine becomes the skeleton that also serves as the running platform, and the overall It has a simple structure and the combine can be made smaller. However, the accessories of the combine harvester include a bagging device, etc., and the bagging device also includes a carrier, which is a support pedestal for large grain bags. I am worried about this.

In addition, the structure in which the crawler is attached directly to the threshing machine frame requires considerable ingenuity in attaching the gearbox. In other words, there is a grain bag holder called a carrier in the bagging device, but if this is attached directly to the threshing machine frame made of the thin iron plate, the weight of the grain bag will be reduced. As a result, the attachment parts of the thin steel plate frame become loose or break.

The same applies when installing the gearbox that rotates the crawler and when installing the prime mover. (Means for solving the problem) In this way, the crawler of the traveling device can be directly attached to the lower part of the threshing machine frame made of thin iron plates, and the reaping device can be attached to the front part of the threshing machine frame. If a combine is formed, insufficient strength is inevitable.

Therefore, in the present invention, a pair of right and left supporting punches 4, 4 in the front and back direction is installed at the bottom of the threshing machine 1 whose outer plate is formed of a thin iron plate.
The front sides of the supporting villages 4 and 4 are provided so as to protrude forward from the threshing machine 1, and the reaping device 18 is installed at the front position of the threshing machine 1, and the cutter or dropper 25 and bag are installed at the rear position. A stuffing device 23 is provided, and front and rear punches 27 are fixed to the outer walls of the left and right sides of the threshing machine 1 at a higher level than the support punches 4, respectively.
- The front end 28 and rear end 29 of the thresher 27 are made to protrude from the threshing machine 1 and are connected by a front connecting village 30 and a rear connecting village 31, respectively, and the rear connecting pestle 31 protrudes long in the direction of the mowed land side L. The carrier fixing village 32 is formed, and the rear wall surface 35 of the gearbox 34 is fixed to the front connecting punch 30 by contacting it, and the shaft 37 protruding left and right from the gearbox 34 is attached to the supporting village 4. The gist of the combine harvester is that a support village 39 for fixing the prime mover 38 is connected to the gear box 34 and protrudes from the gear box 34 toward the mowed land side L'.

(Structure) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a threshing machine, the outer wall frame 2 of which is entirely formed of thin iron plates, and the threshing machine 1 has a slot in the center position in the left-right direction. As shown in Figures 2 and 3, V-shaped support parts 3 and 3 that protrude downward are formed, and support villages 4 and 4 that extend in the front and rear directions are formed at the lower ends of the support parts 3 and 3.

The support village 4 has a claw 5 that rotates in the front and back direction.
5 is installed. Therefore, the cloves 5, 5 have a structure that is directly fixed to the lower end of the threshing machine 1, which is different from a conventional combine harvester in which the threshing machine 1 is mounted on a chassis. The supporting villages 4, 4 do not protrude to the rear of the threshing machine 1, but do protrude to the front.

Reference numeral 6 denotes a straddling portion between the supporting portions 3, 3 formed by forming the supporting portions 3, 3.

The front and rear side walls 7, 7 of the threshing machine 1 are substantially vertical, and a threshing chamber 8 is formed in the upper part between the side walls 7, 7. A handling barrel 9 is built in the threshing chamber 8, and the threshing chamber A hardwood supply chain 10 is attached to the outside of the mowed field side P of 8.

A winnowing chamber 11 is formed in the lower part and side of the threshing chamber 8, and a winnowing winnow 12 is installed below the grain supply chain 10 for blowing a sorting wind toward the cutting field side L. A swinging shelf 13 is attached to the lower part, and a grain removal conveyor 14 is also provided.

The mowed land side L' of the wind selection room 11 is provided with a second receiving gutter 15 and a second grain take-out conveyor 16, and a second grain take-out conveyor 1.
A second grain cylinder 17 is installed to return the second grain taken out by 6 to the threshing chamber 8. The threshing machine 1 is mounted in such a direction that the sorting air is blown in a direction perpendicular to the forward direction of the crawlers 5.

A reaping device 18 is provided at a front position of the threshing machine 1. 19 is a cutting body of the reaping device 18, 20 is an upstream device for raising the grain to be harvested, 21 is a cutting blade, and 22 is a grain conveyor for transporting the harvested grain to the grain supply chain 10 of the threshing machine 1. It is the body.

At the rear of the threshing machine 1, a bagging device 23, a control device 24, a cutter or dropper 25, etc. are provided.

Therefore, the support portions 3 and 3 of the threshing machine 1 are provided.
At the corners 26 and 26 of the space of the mold, there are punches in the front and back directions (
(angle steel, etc.) 27 and 27 are brought into contact and fixed, and both the front end 28 and the rear end 29 are made to protrude in both the front and rear directions.

And between the protruding front ends 28 and 28 is the front connecting village 30.
to connect and fix each other, and between the rear ends 29 and 29 is the rear connecting village 3.
When viewed from above, the rear connecting punch 31 projects and extends in the direction of the bagging device 23 to form a carrier fixing punch 32, and the carriers 33 are stacked on the carrier fixing punch 32. It is fixed.

Further, a gearbox 34 is provided on the front side of the threshing machine 1 to transmit the rotational power of the prime mover 38.
Thereafter, the wall surface 35 is attached to the front connecting punches 3 and fastened with a stopper 36, and the shafts 37, 37 protruding from the gaboxes 34 to the left and right sides are supported by the support villages 4, 4.

Further, a support punch 39 for fixing the prime mover 38 is projected from the gabox 34 toward the mowed land side LI.

(effect) Next, we will discuss the effect.

Since one embodiment of the present invention has the above-described configuration, the crawler 5, 5 If you rotate
The standing grain is separated, the hanging grain is sulfurized by the sulfurizer 20, the root is cut by the cutting blade 21, and the grain is moved to the grain feed chain 10 by the grain transporter 22. let me,
The grain tips are supplied into the threshing chamber 8 by the grain supply chain 10 and threshed by the handling drum 9.

The threshed grains are subjected to the sorting wind of the winnower 12 in the wind sorting room 11, and the sorted first grains are transferred to the first grain extractor conveyor 14.
The second grains, such as cut ears, are received in the second receiving trough 15, and the second grains taken out by the second grain take-out conveyor 16 are funneled in the second tin barrel 17 and sent to the threshing room 8. reprocessed within.

The straw 9E that has been threshed in the threshing room 8 is guided to the cutter or dropper 25 for processing, and the first grain taken out by the first grain take-out conveyor 14 is guided to the bagging device 23 and packed into bags. It will be done. (Effects) However, when looking at the combine harvester that exhibits the above-mentioned effects of the present invention, the clofs 5, which are the traveling devices thereof, are supported by the supporting parts 3, 3 formed at the lower part of the threshing machine 1. In addition, unlike conventional products, the present invention does not consist of a chassis with a crawler 5 and a threshing machine 1 mounted thereon.

Therefore, it can be said that the mounting structure of the crawlers 5 and 5 is much simpler than that of a subordinate structure in which the threshing machine 1 is mounted on the chassis, but on the other hand, since there is no chassis, the overall structure is much simpler. It is unavoidable that the strength will be insufficient. Moreover, since there is no mounting chassis, all the equipment is a threshing machine.
It would have to be attached to itself. However, in the present invention, a pair of right and left supporting punches 4, 4 in the front and back direction is attached to the lower part of the threshing machine 1 whose outer plate is formed of a thin iron plate, and the front side of the supporting punches 4, 4 is located closer to the thresher 1 than the threshing machine 1. A reaping device 18 is installed at the front side of the threshing machine 1, and a cutter or dropper 25 is installed at the rear side of the threshing machine 1.
and a baggage device 23 are provided, and on the outer wall surfaces of the left and right sides of the threshing machine 1, there are longitudinal villages 27 and 27 on the upper layer than the bearing punches 4, 4.
27 are abutted and fixed, respectively, and the longitudinal villages 27 and 27 are
The front end 28 and the rear end 29 of the threshing machine 1 project from the threshing machine 1 and are connected by a front connecting punch 30 and a rear connecting punch 31, respectively. A carrier fixing punch 32 is formed, and a shaft 3 is fixed to the front connecting village 30 by touching the rear wall surface 35 of the gap box 34, and protrudes from the gap box 34 to the left and right sides.
7 on the support punch 4, and the support village 39 for fixing the prime mover 38 from the gear box 34 to the mowed ground side L'
Since the gist is a combine harvester that is installed protruding towards this direction,
In particular, the support villages 4, 4 in the longitudinal direction are provided at the bottom of the thresher 1, and the shafts 37, 37 for rotating the crawlers 5, 5 are connected, so the crawlers 5, 5 are supported at the bottom of the threshing machine 1. The structure is also durable enough.

(b) Fore-and-aft punches 27.2 installed on the upper floors of supporting villages 4.4
The rear ends 29 of 7 are connected at the rear connecting village 31, and the rear connecting punch 31 is made to protrude long in the direction of the cutting land side L to form the carrier fixed punch 32. By providing the carrier 33 on this, Not only can a heavy grain bag be supported, but also the filled grain bag can be easily discharged to the mowed land side L.

C. Since the front ends 28 of the front and back shafts 27 and 27 are connected by the front connecting punch 30, and the rear wall surface 35 of the gearbox 34 is brought into contact with and fixed to this, the gearbox 34 can be supported robustly. Without, front and rear direction village 27, 27
This also has the effect of reinforcing the threshing machine 1.

Since the supporting punch 39 for fixing the prime mover 38 is provided protruding from the gearbox 34 toward the mowed land side L', the prime mover 38 can be firmly mounted on the mowed land side L' without interfering with work.

E. Due to the presence of the supporting punches 4, 4 and the longitudinal villages 27, 27, the frame 2 of the thin iron plate threshing machine 1 can also be used as a running platform, so a 4-type combine harvester can be obtained.

This effect is achieved.
