Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power transmission device for a 3- to 4-row reaper.

A mowing machine for the binder in the combine, a dividing body that determines the width of the cutting pile by separating the culms of the husks, and a raising device that lifts and conveys the tip of the ears and causes the culms to lie down and stand up. A cutting blade that cuts the roots of the erected culms, a scraping device that guides the culms to a conveyance path, and a raking device that captures the tips and roots of the culms and transports them toward a threshing machine, etc. It is equipped with both tip and root conveying devices.

There are many types of such reapers, ranging from small machines that cut 2 rows to large machines that cut 5 to 6 rows, depending on the number of rows to cut the culms. The number of pieces is different. Of these, 3 to 4 are relatively in high demand.
Conventionally, a row trimmer is generally equipped with four cuttings and three pulling devices, and the culm can be guided one row at a time between adjacent cuttings, or two rows can be guided between two of them. After being pulled up in the pulling path of the row, the bundles are combined into a single bundle by a conveying device and conveyed.

However, such conventional 3- to 4-row mowers,
Considering the number of rows to be cut, the lifting devices and conveying devices are all large and complex in structure, making it impossible to provide them at a low price. That is, two culms are guided to one OSS branching body of the two-row cutting system, and one culm is guided between the adjacent branching bodies on the other side.
If the plant is edible in rows, the row width at the base of the plant is approximately m.By combining the rows into one row at the tip, the cutting heights of the inner and outer rows will be uneven. In many cases, the handover to the transfer device is not carried out smoothly.

Therefore, a small auxiliary pulling device is installed in the middle part of the pair of left and right pulling devices, and the culm of 93 to 4 rows of culm is divided into four cuttings by the left and right pulling devices and the auxiliary lifting device. Between 1
Progress is being made in the development of a good harvesting composter that guides and transports each row or two rows at a time. However, in such a reaper, since the auxiliary hoisting device is not designed properly, its drive system must be installed separately from the drive systems of the left and right hoisting devices due to the hoisting path. There is a high risk that the base of the husk will be lifted up and the drive system components will fall during transport, causing the culm to fall down and become a stubble. .

The present invention has been made with the above points in mind.
Nine auxiliary lifting scissors are installed in the middle of the pair of left and right main lifting devices, drivingly connected to a transmission shaft that is supported through the dividing pipe in the center of the machine, and a rotary scraping body pipe. The present invention provides a power transmission device for a reaper that is connected for driving with a transmission shaft, thereby simplifying the structure and facilitating the raising and conveying of the culm.
