Description

[Detailed description of the invention] The present invention relates to a ti three-row reaping machine.

A combine harvester or a binder reaper consists of a dividing body that separates the husks in the field to determine the cutting width, a lifting device that lifts and transports the tip of the husks that have fallen down, and a device that erects the husks. a cutting blade for reaping the base of the culm; a raking device for guiding the cut culm to a conveyance path; It is equipped with both base and conveyor devices. Generally, a three-row reaper is equipped with four splitter bodies and three pulling devices, and the culm is divided into one and two rows and guided between adjacent splitters. are pulled up in two rows of lifting passages and then combined into a single bundle by a conveying device.

However, in conventional three-row reapers, the three lifting devices are formed at the same height, so that each lifting lug collapses at the same height to release the culm from its hold. In addition, the upper ends of the three lifting devices are connected by a frame and are driven and connected to each other within this frame, so that the tips of the culms released from the lifting lugs are There were problems in that the grain was squeezed by the frame, causing shedding and grain breakage, and the space after release was narrow, which obstructed the transport of grain O and caused it to accumulate easily.

The present invention has been made in view of the above points. Therefore, an auxiliary lifting device shorter and smaller than the left and right main lifting devices is arranged parallel to the main lifting device in the middle part of the left and right main lifting devices, which are parallel to each other. By standing each of these lifting devices upright and driving them to rotate from below, and by setting the operating end of the main lifting device at the same level as the upper end of the auxiliary lifting device, the end of the lifting device can be left wide open. The purpose of the present invention is to provide a reaper that facilitates the transportation of shell culms and prevents the occurrence of grain shedding due to straining.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Its height is set so that it is at the same height as the upper end of y.

As a result of providing each lifting device 16, 17.25 in this way, there is a gap between the auxiliary lifting device 25 and the main lifting device 16.
Two culm lifting passages are formed by the running of the lugs 31 and 24, and one passage is formed between the auxiliary lifting device 25 and the main pulling device 17 by the running of the two groins 24. A channel for raising the culm of the rays is formed.

32# is a cutting blade formed in the shape of a clipper, and is supported in the longitudinal center part of the grass dividing pipes 14b to 14 and is installed perpendicular thereto, and above it is a pair of left and right blades. Container bearings 33 are provided to protrude obliquely upward at equal intervals on both sides of the auxiliary lifting device 25, centered directly behind it. A rotary raking body 34 formed in the shape of a gear is attached to the raking shaft which is rotatably supported by each raking bearing □ll-1 33 and is drivingly connected to the above-mentioned raking gear drive shaft, and the rotating raking body 34 is formed in the shape of a gear and engages each other's teeth. TomoK is attached to the shaft.

One end is supported by a scraping bearing 33, and a belt pulley in a scraping belt case 35 is arranged in an S-shape, and this belt pulley and a scraping belt case 35 are connected to each other. ! G! It is suspended in ! In addition, a conveyor chain 3 is stretched between the sprocket on the raking shaft and the sprocket on the reaping gear 12 side. Between the reaping raking unit 9 and the threshing machine 5 configured in this way, there is a tip conveying device 4 for conveying the tip of the harvested culm.
0 and a root conveying device 41 that conveys the root portion are vertically mounted substantially parallel to each other.

The operation of the reaping pattern 8 configured as described above will be explained by taking three rows of reaping as an example. As the machine advances, the culm cluster Fi in the field is pushed through the four cutting bodies 14b to 14, and is guided one by one to the three rows of passages between the adjacent cutting bodies. Main lifting device 16 and auxiliary lifting device f2 in the passage! By facing the starting end of the ear, the tip of the ear can be scooped up by the lugs 24.11 that rotate while standing up. Further, the tip of one of the remaining yarns is scooped up by the lug 24 of the other main pulling device 1T. The tip of the scooped-up culm is lifted up and conveyed by the lugs 24 and 31 as the machine advances, and the base of the culm is conveyed to the reaping position by a rake belt.
It is harvested with the cutting blade 32. The root portion of the cut culm is scraped by a rotary scraper 34, and conveyed by a conveyor chain 39, and the tip of the culm is pulled up by the devices 16, 17.
25, and the tip and root portions are caught and conveyed by the tip and root conveying devices 40 and 41. The nine-hulled culms are conveyed, with the root portion taken over by the feed chain 4, and while being conveyed, the tip portion is handled and threshed with a barrel.

In the reaping machine 8 that operates as described above, the auxiliary pulling device 25 in the center of the three lifting devices 16, 17, and 25 is formed short, and the main pulling device 18,
17C) The lug 24 is configured to lie down at the upper end position of the auxiliary lifting device 25, and each lifting device 1
Since @, 1F, and 25 are each independently driven from below, a large space is formed above the auxiliary lifting device 2s and is opened upward. Therefore, even if the tip of the shell culm released from the lug 24.31 moves with the movement of the machine, the movement path of this tip will include:
There are no obstacles like traditional horizontal frames, so
Grain culms are transported very smoothly.

As is clear from the above explanation, according to the present invention, 3
In a row reaper, a shorter and smaller auxiliary pulling device is installed in the middle of the left and right main pulling devices, which are parallel to each other, in parallel with the main pulling device, and these pulling devices are independent of each other. By rotating the main pulling device from below and setting the working end of the main pulling device at the same level as the upper end of the auxiliary pulling device, there are no obstructions at the pulling end and this tube place can be used for large winding. Because it is opened, the tips of the culms that are released from the lifting device and transported are not held back, and some of the grains due to shedding and ear breakage can be reduced. The transportation of the culm is extremely difficult.
