Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a combine harvester for harvesting and threshing grain culms.

(b) Prior Art Conventionally, many multi-row combine harvesters capable of cutting five or more rows have already been known.

(c) Problems to be solved by the invention In the known combine harvester, the reaping frame and the drive mechanism of the raking device were configured in a fixed manner, so that it was not possible to increase the number of reaped rows.

(d) Means for solving the problem A grain culm conveying device is interposed between the threshing device mounted on one side of the machine and the reaping device disposed in front of it, and A driver's seat is provided in the front, the cutting width of the already cut field side of the above-mentioned reaping device is made wider than other parts,
In a multi-row mowing combine in which a raking band is provided outside a raking path for one row on the uncut land side and on other raking paths, one row of raking is performed on the uncut land side of the reaping device. To increase the width, the raking band and the additional raking wheels on the outside of the raking route on the unmown side are connected to another transmission case that is interlocked with the outside of the transmission case installed on the unmowd side. In addition to driving, the additional raking wheel is removably attached to the separate transmission case using a support frame, and a horizontal frame opposite to the horizontal frame of the reaping frame is protruded on the inner side near the rear of the auxiliary frame to be added on the uncut field side. This horizontal frame is removably attached to the uncut field side of the reaping frame with bolts, and the raking band on the outside of the raking path on the uncut field side is connected to the raking band formed inside the auxiliary vertical frame. The above-mentioned problem was solved by replacing and installing it along the outside of the route.

(E) Operation In a combine harvester with the basic type of reaping row number, reaping and threshing is performed while the machine is running so that the end of the uncut field side fits between the rows where it enters.

When increasing the reaping width of the combine by one row, an auxiliary vertical frame is screwed onto the uncut field side of the reaping frame, and a separate transmission case at the rear of the auxiliary vertical frame is used to increase the cutting width by one row. When the raking body is replaced and installed, the newly installed raking body is driven by a separate transmission case to rak the grain culms in the increased raking path, and the raked grain culms are removed from other grain culms. It merges with the grain culm from the raking path and is transported later by a vertical conveyance device, and is threshed by a threshing device.

(F) Example An example of the present invention will be explained with reference to the drawings.

The shifter 44 connects to and disengages from a clutch pawl carved on the side surface of the clutch pedal 45, and the shifter 44 connects the wire 4 to the traveling clutch pedal 45.
6, so when the traveling clutch pedal 45 is depressed during work, the traveling clutch is disengaged, and since the reaping device and vertical conveyance device 16 are interlocked with the traveling device 2, the machine body, reaping device, etc. are stopped. At the same time, the clutch 43 is disengaged and the lifting device is also stopped.

Furthermore, a guide rod 47 is provided on the upper surface of the stock head transport body 17, and the lower end of this guide rod 47 is connected to the outside of the rear end of the frame 48 that holds the clamping rail 26a of the stock head transport body 26. It is pivoted to the side by a pin 50 so as to be rotatable back and forth as shown by solid lines and chain lines in FIG. Since the position is very close to the horizontal axis P, which is the center of rotation of the vertical conveyance device 16, in side view, the guide rod 47 can freely tilt around the base and come close to the conveyance surface of the stock head lifting body 17. It always acts as a presser.

Furthermore, when performing manual handling work, when the main clutch of the submission 57 is disengaged by operating the change lever, the traveling device 2 and the pretreatment device are stopped, so the clutch of the lifting and supplying device is closed without depressing the traveling clutch pedal 45. 43 can be kept in the engaged position, and in this state, when the guide rod 47 is rotated to the forward A position (for shallow adjustment) or B position (for deep adjustment) as shown in FIG. , the worker can feed the hand-harvested grain culms to the stock head lifting body 17 and the ear side lifting body 18 located at a lower position than the supply port 33 in a comfortable posture, and when returning to the harvesting and threshing work. ,

The front part is received by the stopper 52 and set in a predetermined guiding attitude.

Thus, the stock head lifting body 17 and the ear side lifting body 1
Since the diameter of the driving sprockets 37 and 38 of No. 8 is smaller than the diameter of the driven sprocket 40 of the feed chain 1a, the conveying speed of the feed chain 1a is V ₁
is larger than the lifting speed V ₂ of the lifting device.

Horizontal frames 76a and 77a are provided protrudingly opposite to the horizontal frames 76a and 77a, and these horizontal frames 76a and 77a are removably attached to the unmown side of the reaping frame 74 with bolts 76b and 77b,
Since the raking band on the outside of the raking path on the uncut land side is replaced and installed so as to follow the outside of the raking path formed inside the auxiliary vertical frame 75a, the mowing width is wide in the area on the already mowed land side. This allows the operator to visually check the cutting area from the driver's seat immediately behind the mower and to accurately steer the mower to avoid leaving uncut leaves. As a result, the horizontal width of the reaping device is abnormally expanded and the left-right balance deteriorates significantly, as when a wide reaping means is added outside of the wide mowing width area on the already mowed field side. The row spacing and the cutting width do not match, and even when the cutting width is increased, the wide cutting width part on the already cut field side is located almost in front of the driver's seat. It is possible to easily perform steering operation so as not to leave any uncut material while accurately visualizing the time of reaping, and it is also possible to prevent the cross-feeding route from becoming long.

In addition, the added reaping and raking means can be driven using the existing transmission case, and the grain culm harvested by the increased reaping means can be used by replacing the existing raking band, so the number of reaping rows is increased. It is possible to significantly reduce the cost of the driving device and the scraping means due to the increase in the amount.
