Description

[Detailed description of the invention] The present invention provides a stem culm lifting device that moves the stem culm locking claw in a sideways protruding posture upward from near the ground, and also separates the stem culm lifting device in front of the lower end side. This invention relates to a reaping and harvesting machine that arranges grass bodies.

In the above-mentioned reaping and harvesting machine, conventionally, when inspecting or adjusting the stem culm processing device such as the stem culm transport device or the reaping device located behind the pulling device, the narrow gap between the stem culm locking claws in the pulling device is required. The workers had to reach the work area from the side and outside of the aircraft, making the work difficult and reducing work efficiency.

The purpose of the present invention is to modify the lifting device so that work such as inspection and adjustment behind it can be done easily and efficiently.

In the present invention, in the above-mentioned reaping and harvesting machine, the stem culm pulling device can be slid in the lateral direction of the machine body and oscillated in the longitudinal direction of the machine body with respect to the support member on the lower end side. a working posture in which the plant is attached and stands up at the rear of the grass cutting body, and a forward swinging posture in which it lies down to the front side of the body on the side of the grass cutting body to open the rear of the stem culm pulling device; The feature is that the posture can be changed freely, and it operates and produces the following effects.

That is, when the stem culm pulling device is slid and swung relative to the support member, the stem culm pulling device moves away from the grass cutting body from behind to the side so as not to come into contact with the grass cutting body during lodging. The machine can be placed in a forward rocking position with the machine folded down and rocked to the front of the machine to open the rear of the pulling device, or it can be placed in a working position standing up on the rear side of the weeding machine and the machine can be seen in the forward and backward direction. Due to the duplication of the stem culm from the cutting plant, it smoothly inherits and raises the stem culm to function. However, as the stem culm pulling device avoids contact with the cutting body and assumes a forward swinging posture, the stem culm pulling device is forced to fall down and swing while its lower end remains positioned on the rear side of the cutting body. Compared to the case where the stem culm lifting device is configured, the angle of collapse from the working posture to the forward swinging posture of the stem culm lifting device can be made larger, so that the degree of opening at the rear of the lifting device can be increased. In addition, by allowing the stem culm pulling device to avoid contact with the weeding body by sliding sideways, it is possible to avoid the trouble of attaching and removing the weeding body, unlike in the case where the device is configured to do so by removing the weeding body. By simply changing the posture of the stem culm lifting device, the rear of the lifting device can be opened or returned to its original closed state.

Therefore, the front of the part to be worked on behind the lifting device is wide open to allow easy insertion of the hand into the part to be worked on, and a large working space is secured in front of the part to be worked on, allowing for desired inspections, adjustments, etc. can now be done easily and quickly. Furthermore, the front of the work target can be opened and closed simply by changing the posture of the stem culm lifting device, and inspections and adjustments can now be carried out more efficiently in terms of the associated front opening and closing operations.

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

As shown in FIGS. 1 and 2, a crawler traveling device 1, a threshing device 2, an engine 3 for driving various devices,
At the front of the machine equipped with the driver's seat 4, etc., there are a pair of left and right stem culm lifting devices 5, 5 for moving the stem culm locking claw 5a in a sideways protruding position from near the ground to the rear and upward direction, and a pair of left and right stem culm lifting devices 5, 5 for lifting the stem culm. a clipper-type reaping device 6 for cutting the base of the stock;
The reaping processing unit, which is equipped with an auxiliary conveyance device 7 for merging the harvested stem culms, a rear conveyance device 8 for conveying the merged stem culms to the rear threshing device 2, etc., is pivoted so that it can be raised and lowered around the horizontal axis X with respect to the machine. It is attached to a cylindrical lifting frame 9 that also serves as a supporting transmission case, and is further provided with a hydraulic cylinder 10 that lifts and lowers the lifting frame 9 relative to the machine. The work of raising the stem culm, reaping, and threshing is performed automatically and continuously, and the reaping processing unit is raised and lowered to adjust the cutting height and to avoid contact with the ground when driving on headlands or on roads. An operable combine harvester has been constructed.

To install the lifting device 5, as shown in FIGS. 1 to 3, a horizontal cylindrical body 12 supported at the lower end of the back surface of the lifting case 11 is rotatably and slidably fitted and supported. Axial pivot rod 13
is fixed to the weeding attachment frame 15 extending forward from the reaping drive case 14 in a horizontal position fixed to the tip of the lifting frame 9, and the lifting case 11
Cylindrical input case 1 installed vertically toward the upper end of the back of the
6 is inserted into the upper end of the support frame 17 which also serves as a transmission case and is set upright from the reaping drive case 14 so as to be able to be freely pulled out forward, and the stopper 18 that abuts and prevents the input case 16 from coming off is attached to the support frame 17. An input rotating shaft 19 is detachably bolted to the input case 16 and is rotatably supported within the input case 16.
, with respect to the transmission shaft 20 in the support frame 17,
The bevel gear is interlocked so that the stopper 18 can be freely detached from the front, and the input case 16 and the support case 17 are moved forward by first removing the stopper 18 and swinging the case 11 forward a little.
Then, by moving the case 11 to the inside of the body so that it does not overlap the weeding body 21 when viewed from the front, and finally, by swinging the case 11 forward, The configuration is such that the posture of the lifting device 5 can be changed by performing the reverse procedure. That is, the lifting device 5 is brought into a disconnected state from the support case 17, and is operated to slide in the lateral direction of the machine body and swing in the longitudinal direction of the machine body with respect to the pivot rod 13 as a support member. Then, the pulling device 5 stands up at the rear of the weeding body 21 and assumes a working posture in which the planted stem culm from the weeding body 21 is pulled up by the stem culm locking claw 5a. It is arranged to lie down toward the front side of the fuselage on the lateral side, and assume a forward swinging posture in which the rear side of the lifting device 5 faces upward and the rear side of the lifting device 5 is opened.

In short, when the lifting device 5 is switched to the forward swinging position, the pawl drive chain 23 and chain winding sprocket 24 inside the case 11 can be refueled or the case 11 can be refueled through the hole 22 formed in the back of the lifting case 11. When inspecting and removing straw waste,
In addition to making it possible to inspect and adjust the lifting device 5, it is also possible to oil the reaping device 6 and auxiliary conveyance device 7 located behind the lifting device 5, and to remove accumulated straw waste and clogged stem culms. The removal work can be carried out without being hindered by the lifting device 5.

Further, the structure for driving the lifting device 5 in a state that allows it to swing back and forth can be modified in various ways.

Furthermore, the present invention can be applied to the mounting structure of a pulling device installed in various types of reaping and harvesting machines such as binders as well as combines.
