Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping machine suitable for use in a shed combine harvester for cutting two to three rows.

A combine harvester or binder reaper has a dividing body that scrapes the culm in the field and determines the cutting width, a lifting device that raises and transports the tip of the culm that has fallen down, and a lifting device that raises the tip of the culm that has fallen down. A cutting blade that harvests the root portion of the husk culm, a scraping device that guides the cut husk culm to a conveyance path, and a raking device that holds the tip and root portion of the husk culm and transports the culm toward a threshing machine, etc. It is equipped with both tip and root conveying devices. In general, a two-row reaping machine is equipped with three splitter bodies and two pulling devices, and the two-row culm is moved between the central splitter body and the outer splitter body. The structure is such that the threads are guided one by one and then pulled up while merging into a single thread in the pulling path between the left and right pulling devices. *9. A 3- to 4-row reaper is equipped with 4 cutting bodies and 3 pulling devices, and the reaper can move one row between adjacent dividing bodies to one of them. The structure is such that the culms that have been guided in two rows are pulled up in two rows of lifting passages, and then merged into a single bundle by a conveying device and transported.

However, 3-4J! A reaping machine for reaping grass has not only a pulling device but also a conveying device, etc., all of which are large and have a complicated structure. Therefore, it is not possible to provide this at a low price, so if possible, a small machine with two rows of cutting is preferable. It is desirable to be able to mow at least three rows. Conventionally, a two-row mower has been used to guide two culms between adjacent weeds on one side, guide one culm between adjacent sheaths on the other side, and pull them up while merging them with a pulling device. In some cases, 3-row cutting is performed with a 2-row mower, but in this case, the inner row is cut by combining the row width of 1% at the tip of the stalk into a single row. The cutting height was uneven between the culm of the outer row and the culm of the outer row.The transfer to the conveying device was not carried out smoothly and the cutting height was often cut. A small lid auxiliary pulling device is installed in the middle part, and the three culms that have been raked by the four splitting bodies are guided one or two at a time between each of the left and right pulling devices and the auxiliary pulling device. Development of a reaper that can raise and transport the grass is underway. However, in such a reaper, by providing an auxiliary pulling device, the space between the p1 pulling device and the cutting blade, which requires a driving device, becomes narrow, and the three-striped shell is used. There are many concerns that the flow of the shell culm before harvesting will be impaired due to the passage of the culm, so it is necessary to solve this type of drawback when developing it.

The operation of the nine-row cutting machine 9 constructed as described above will be explained by taking a three-row cutting machine as an example. As the machine moves forward, the rows of culm rows in the field are raked by the four weeding bodies 15b to 15e and guided one by one to the three rows of passages between the adjacent weeding bodies.
24 of these is because the starting ends of the main lifting device 16 and the auxiliary lifting device [2B are facing in the passage, and the puffer fish 2G and $7 move around while standing up. You can be scooped up. 9. The tip of the remaining one thread is scooped up by the blowfish 20 of the other main pulling device 1T. The tip of the scooped-up culm is conveyed on the plow by the lug 20.37 as the machine advances, and the base of the culm is conveyed to the reaping position by the rake belt 42, where it is reaped by the cutting blade 3. It will be done. The root portion of the cut culm is scraped by a rotary scraper 40, conveyed by a conveyor chain 45, and the tip portion is pulled up by the main lifting device 16.1.
7, and the tip and root portions are captured and conveyed by the tip and root conveying devices 47 and 48. The conveyed husks are conveyed with the root portion taken over by the feed chain 4, while the tip portion is threshed by a decoloring cylinder.

In the reaping machine S that operates as described above, the auxiliary pulling device 28 is supported by the conduction pipe 31 from the grass cutting pipe 14 side, and the shafts 25, 27, 33 in the grass cutting pipe 14 and the conducting pipe 31 are Since it is driven from the driving side via
Since only the weeding pipes 14a, 14. and the conduction pipe 31 are present, the culm can be transported smoothly without any hindrance. By providing the drive system for the weeding pipes 14n to 14 and the auxiliary pulling device 28 below the cutting blade 3I, the conveyance of the culm before cutting becomes smoother, and the rotary raking Since there is no resistance between the body 4o and the cutting blade 38, the plants are well aligned during raking.

As is clear from the above explanation, according to the present invention, in a reaper, an auxiliary pulling device is provided in the middle of a pair of left and right main pulling devices, and a good conduction shaft that is drivingly connected to the auxiliary pulling device is provided at the center. The transmission shaft and the drive shaft from the driving side are connected in a transmission box provided in the weeding pipe, and the cutting blade for cutting the culm is inserted into the weeding pipe. By supporting the culm above the pipe, there is no obstacle in the transport path from lifting the culm to reaping and raking, so the culm can be transported smoothly. This not only improves the cutting performance but also makes it possible to utilize the grass dividing pipe to a greater extent, and greatly simplifies the structure of the power transmission system. In addition, since there is a grass dividing pipe between the cutting blade and the ground, the cutting blade does not bite into the soil, and it also prevents damage to the cutting blade when loading and unloading the machine from a vehicle. The durability of the cutting blade is improved. By resolving these obstacles to development, it will become possible to perform 3-row mowing with a small machine similar to a 2-row mower with the same performance as a large machine. , equipment costs are saved and the cost of harvesting is reduced.
