[Prior Art]

 Conventionally, when cutting grain culms that have been planted near the ridge by combine harvesters, when cutting the ridge toward the ridge, the cutting section is raised so that the cutting edge of the cutting body is raised against the ridge. However, if the reaping section is raised in this way, the cut culms become ultra-short culms, and if they are handed over to the feed chien and are fed laterally into the handling room, they become shallow handling and are left untreated. Occurs. Therefore, in the case of manually adjusting the handling depth, it is not enough to operate the handling depth adjusting lever deeply on the handle, and the handling depth for detecting the culm length at the inlet of the handling room In the case where a sensor is provided and the handling depth adjusting mechanism is automatically adjusted based on the detection, a handling depth adjusting mechanism for a cut culm which is in an ultra short culm due to the raising of the reaping part is used. Similarly, there is a delay in handling, and the unhandled area is left unhandled.

[0003]

[Problems to be solved by the device]

 In this way, when the grain culm that has been conventionally planted near the ridge by combine harvesters is mowed by advancing the aircraft toward the ridge, the reaping section is forced to rise and the culm becomes an ultra short culm. In view of the fact that unhandled culms are produced, the present invention prevents the unhandled culms from being left unhandled in the garage room even if the cut culms become ultra-short culms. It was invented.

[0004]

[Means for Solving the Problems]

 Therefore, in order to solve the above-mentioned conventional problems, the present invention is a combine machine described at the beginning, which is provided with a handling depth adjusting mechanism in front of the entrance of the threshing section to the culm culm. In the apparatus for adjusting the handling depth in accordance with the above, the handling depth adjusting mechanism is operated to the deep handling knife due to the rise of the mowing section from the normal cutting height position.

[0005]

[Action]

 As a result, the cutting section is set to the normal cutting height position and the machine is advanced to move the planted grain culms in front of the entrance of the slaughter chamber by the depth adjustment mechanism to adjust the stalk depth according to the stalk height of the stalk grain. The threshing process is performed by adjusting the height of the reaping section above the normal cutting height so that the grass bodies do not collide with the ridgeline when it advances near the ridgeline. When the nearby planted culms are also mowed, the mowed culms become ultra-short culms. Since it is corrected to the state and threshed, it does not become a shallow handling, and therefore there is no leftover handling.

【Example】

 Hereinafter, the handle depth adjusting device according to the present invention will be described with reference to an embodiment diagram. As shown in FIG. 2, this combine (3) is a traveling chassis (A) installed on a traveling device (4). ) Is a threshing part in which a feed chain (1) is stretched on the left side and a handling cylinder (5), a swing sorting body (6), etc. are built in and mounted on a traveling chassis (3), and (B) is a weeding body (7) ・ A cutting case (8), a cutting blade (9), a vertical conveying chain (10), a tip conveying tine (11), etc., provided in the preceding stroke of the threshing section (A), (C) is an straw processing unit that looks into the end of the straw chain (12), (13) is a control unit, (14) is a grain barrel (15) from the threshing unit (A). It is a grain tank that stores via a continuous cutting of planted grain culms to the vertical transport chain (10) and the tip transport tine (11). Then, the threshing section (A) conveys it to the crocodile, sandwiches it from the handling room inlet (2) with the feed chain (1), and laterally feeds the handling room to perform threshing treatment, and the grain tanks (14) The threshed straw is carried out by the straw chain (12) and stored in the straw processing section (C) while being stored in the.

Further, the mowing section (B) is provided with a mowing lifting lever () which is provided in the control section (13) with an input shaft for supplying power to each part of the mowing section (B) as a rotation fulcrum (P). 16) The rod (17a) of the hydraulic cylinder device (17) is moved up and down by the operation of 16) so that it can be moved up and down, and its rotation fulcrum (P) is located in the vicinity of the starting end of the feed chain (1). I am letting you.

Further, the vertical conveying chain (10) is moved by a manual operation by the handling depth adjusting lever (18) to move the terminal end (10a) outward from the starting end of the feed chain (1). A known handling depth adjusting mechanism for adjusting the handling depth of the harvested culm by bringing them close to each other is provided in front of the handling room entrance (2). Although not shown, this adjustment mechanism is provided with a handling depth sensor for detecting the culm length at the entrance (2) of the handling chamber, and the handling depth adjusting mechanism is activated based on the detection to automatically adjust the handling depth sensor. It is also possible to use known means for

Therefore, in FIG. 1, reference numeral (19) is a wire, one end of which is connected to the handling depth adjusting lever (18) through a connecting member (20) having a long hole (20a) and the other end. The tips of the rods (17a) of the hydraulic cylinder device (17) are connected to the saws, respectively, and the rotation fulcrum is provided by the extension of the rods (17a) by the operation of the reaping lift lever (16). The wire (19), the connecting tool (20), and the handling depth adjusting lever (18) are moved along with the ascending of the mowing part (B) about the axis (P) from the normal cutting height position (a). The cutting depth adjustment mechanism is operated via the deep cutting arm to adjust it to the deep cutting position, and the mowing section (B) is lowered to the normal cutting height position (a) by the mowing lifting lever (16). When this is done, the handle depth adjustment mechanism works in reverse to restore the handle depth to the standard one. .

It should be noted that the handling depth adjusting mechanism operates by raising the mowing part (B) from the normal mowing height position (a), but one end of the wire (19) has a long hole (20). Since it is connected to the handling depth adjusting lever (18) through the connecting tool (20) having a), the normal cutting height position (a) has a certain width in the vertical direction. The width depends on how to set the length of the long hole (20a) in the longitudinal direction.

Therefore, while the cutting unit (B) is set to the normal cutting height position (A) and the machine body is advanced, the handling depth adjusting lever (18) can be operated according to the culm height of the cut culm. For example, the lower end that engages with the connecting device (20) moves inside the elongated hole (20a) to activate the handling depth adjusting mechanism. If you change from standard handling depth to deep handling (c), you will be adjusted to shallow handling and cut culms will be supplied from the handling room inlet (2) and threshed.

Then, when the reaper is raised near the ridge and the reaper lifting / lowering lever (16) is operated to raise the reaper (B) as shown in FIG. The height of the culm of the culm to be culled becomes ultra short culm, but the wire (19) is pulled by the raising of the reaping part (B), and one end of the wire (19) has a long hole (20a) of the connecting tool (20) The lower end of the handling depth adjusting lever (18) is locked to the front end of the inside so that the handling depth adjusting lever (18) can be operated with a deep handle. Threshing is done without leaving any residue.

Further, if the cutting section (B) is lowered to the normal cutting height position (a), the handling depth adjusting lever (18) can be operated via the wire (19) and the connecting tool (20). It returns to the standard position and the handling depth returns to the standard state.
