Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping machine suitable for small-sized combine harvesters with 2 to 4 rows of cutting.・Reapers for combine harvesters and binders are capable of cutting through 1lIII husks to increase the cutting width. A cutting body to be determined, a lifting device that lifts up and conveys three parts of the tip of the nine-shelled culm to raise it upright, a cutting blade that stands up and reaps the root part of the nine-shelled culm, and a cutting blade that cuts the root of the nine-shelled culm. It is equipped with a raking device that guides the culm to the conveyance path, and a tip and root image conveying device that holds the tip and root portions of the culm and conveys them toward the threshing machine section. In general, a two-row reaper is equipped with three cutting bodies and two pulling devices, and the two-row culms are separated one by one between the central cutting body and the outer cutting body. After being guided to the left and right pulling devices, it is configured to be pulled up while merging into a single thread in a lifting passage between the left and right pulling devices. A reaping machine capable of cutting 3 to 4 rows is equipped with a 41- section weeding section and 3 pulling devices. The structure is such that the nine-hulled culms are pulled up in two rows of lifting passages, and then merged into one line of Song using a conveying device to be taken in.

However, a reaper with 3 to 4 rows cannot be raised
Not only the equipment but also the conveying equipment are all large and have complicated structures, which makes it impossible to provide them at a low price. It is desirable to make it possible. Therefore, in the past, a two-row mower guided the culms of two rows between adjacent cuttings on one side, and
Ii! ! One row of grain culms is guided between the grains, and the grain is pulled up by a device where they merge and raised, and three rows are cut with a two-row mower]
However, in this case, by combining the row width of X1m into one row at the tip of the stock, the cutting heights are uneven between the inner row culm and the outer row O culm. (The handover to the new transport device was not carried out smoothly) in many cases. It has been proposed that an auxiliary lifting device be installed on the trench nine and two-row side machines to assist in raising the two-row side.
Because the tips of the husks are transported to the threshing machine using a lifting device, the tips of the husks become entangled with each other and conveyance is stagnant. The drawback was that it was not carried out.

The present invention has been made in view of the above points, and consists of a pair of left and right main lifting devices arranged in a square shape when viewed from the front, and an auxiliary lifting device provided in the middle of the main lifting devices. Two of the three or four culms are installed at the rear with a tip conveyor.
The row is pulled up using an auxiliary pulling device and one main pulling device,
By configuring so that one or two of the remaining culms are pulled up by the other main pulling device, and while being harvested, the tip part is collected in the center of the cutting width, and then captured by the tip conveying device,
Small and simple configuration for smooth transportation and pulling of 3 or more culms.
It is a mist that provides a nine reaper that allows for harvesting. Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

It is located. A large number of hoisting chains are suspended in the chain case 1s of these main hoisting devices 1116.17, and run while drivingly connected to the reaping drive shaft by a hoisting drive shaft inside the hoisting pipe 18''. The lugs 20 are arranged at regular intervals 9 and are set in the chain case II by the action of a lug guide so that they stand up only at the lower end of the chain case 19 and the inner lifting passage, and the lugs 20 stand up together with the chain in FIG. It is configured to run in the direction indicated by the arrow mark in the figure. □ Further, there are holes in the middle portions of the left and right main lifting devices 18 and 170.
A shorter and smaller auxiliary pulling device 21 is attached to the upper end of the conductive vibrator 22 that sharpens diagonally upward from the second extending member from the main pulling device 17N of the four extending members of the dividing rod 14. It is erected with its lower end supported by a weeding rod 14. The auxiliary pulling device 21 is disposed in parallel with the main pulling devices 11i and 1F in the side view shown in FIG.
Similarly to ゜17, the chain' runs in the chain case 23 and is arranged on the chain, stands up only at the lower end of the chain case 23 and the main lifting device 16 side, and runs in the direction shown by arrow B in Fig. 1. A large number of lugs 24 are provided. Furthermore, a protrusion 25 having a triangular shape in side view is provided on the front surface of the chain case 23 on the field 4i side to separate and comb the tips of the culms.

Reference numeral 26 denotes a cutting blade shaped like a clipper, which is supported by the outer extension member at the center of the grass dividing rod 14 and is installed perpendicularly thereto. A raking bearing 2T is provided to protrude diagonally forward at a position directly behind the auxiliary lifting device ff121 and at a distance from both sides of the cape. A rotary scraping body 2 formed in the shape of a gear is rotatably attached to the scraping shaft which is supported by each scraping bearing 2T and is drivingly connected to the dead drive shaft, with teeth meshing with each other. At the same time, it is arranged in a V-shape with one end supported by a scraping bearing 21, and a belt pulley in the belt case 2s including 7ICMk is attached to the shaft. A scraping belt 31, which is integrally formed during molding and has nine lugs 3o, is stretched in the scraping belt case 2s. Further, a sprocket is attached to one of the raking shafts 9, and a conveyor chain 32 is stretched between this sprocket and a sprocket provided on the pre-reaping frame 12 side.

On the other hand, in this machine, the removal **s*, there is a culm feeding device, generally designated by the reference numeral 33. Among them, the tip conveyor [34 is a tip chain that runs inside a chain case 35 and is equipped with a large number of lugs 36 at regular intervals, and a nine tip guide 34, 1 that is supported along the running trajectory of the tip of the lugs 36. The root conveying device 38 also includes a root chain 40 running within a chain case 39, and a holding rod 4 supported along the running end of the root chain 40 and biased toward the chain 40.
1. 3.
4, 38 are supported on the side of the threshing machine 5, and
They are interconnected by rods 42.

The operation of the reaping machine 8 configured as above will be explained. As the machine advances, the row of culms in the field is divided into 4 cutting plants15
The strips are swept aside and guided one by one to three rows of passages between adjacent grass cutting bodies 15, and two of these strips have starting ends of the main pulling device 11'l@ and the auxiliary pulling device 21 in the passage. Since the tip is facing forward, the tip of the ear can be scooped up by the lugs 20 and 24 that circulate while standing up. Further, the tip of the remaining one thread is scooped up by the lug 20 of the other main pulling device IT. The tips of the culms that have been scooped up are lifted up and conveyed by the lugs 20 and 24 as the machine advances, and the root portions of the culms are conveyed to the dying position by the raking belt 31, and are carried by the cutting blades 26. be reaped. The cut nine-hulled culm is scraped at its root by the rotary scraper 28 and transported by the conveyor chain 32, and the tip is released from the main lifting device 16° 1T to separate the root and tip. It is captured and transported by the root transport axis fIlt3°8 and the keyaki tip board feeder &33. The husk culm fed ll1i has its root part taken over by the feed chain 4 and is fed by a button, while its tip part is handled and threshed in a barrel.

In the reaping operation performed as described above, the main lifting device f1t16.17 is arranged in a V-shape, and the auxiliary lifting device 21 is provided in the middle. Even at the time of reaping, the outer culms of the grain do not fall inward, so that the cutting heights of all the culms are well aligned and the culms are pulled up smoothly.

In addition to this, because the ear tip conveying device fk34 is separated from the lifting device and installed independently, the grain culms of 3-row and 4-row grains are combed by the lifting device, and the combing is completed. When this is done, the cutting width is collected by the saw cutter, cut, and then transferred to the tip conveying device k34, so that the cutting is carried over smoothly without any accumulation.

Furthermore, since the front of the driver's seat 6 is wide open, the visibility to the weeding rod 15 is extremely good, and there is no possibility of uncut mowing due to incorrect steering.

As is clear from the above description, according to the present invention, in a reaping machine, a pair of left and right main pulling devices are arranged in a V-shape when viewed from the front, and an auxiliary pulling device is provided in the middle. A tip conveying device is installed behind the pulling device, and two of the three or four culms are pulled up using the auxiliary lifting device and one of the main pulling devices, and one or two of the remaining nine culms are pulled up. The culm of each row is pulled up by the other main pulling device for reaping], and the tip of each row is collected in the center of the cutting width and then captured by the tip conveying device. Since the husks are harvested without greatly falling down in the cutting width direction, the cutting height is uniform, and the 3- or 4-row O husks are pulled up and collected in the center of the cutting, and then sent to the tip writing device. The handover will be carried out extremely smoothly. As a result, a small machine designed for two-row mowing can reap three-row mows 9 or more with the same performance as a large machine, reducing equipment costs and harvesting costs. .
