Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a pre-reaping treatment section and a control handle are disposed in front and behind the running wheels of a two-wheeled -shaft type, and the driving of each of the running wheels is individually intermittent. This invention relates to a reaper that is equipped with a steering tool for controlling the direction of the machine.

Conventionally, with this type of reaper, the operator grasps the control handle and raises the pre-reaping section above the ground to maintain it at the desired height while reaping. In addition to maintaining the reaping pre-processing section in a state of levitation above the ground, the operator must also perform turning operations of the aircraft.
People tend to be preoccupied with turning the machine and neglect to maintain the pre-reaping section in a floating state above the ground. This method has the disadvantage that there is a risk that a part of the pretreatment section may be damaged.

Therefore, conventionally, it has been considered to provide a grounding body such as a grounding ring or a bridge at the lower end of the pre-reaping treatment section to keep the pre-reaping section always floating above the surface of the reaping section, but in that case,
During reaping driving, vertical vibrations caused by irregularities in the field, stones, etc. are transmitted to the reaping pre-processing section via the grounding body, and the reaping pre-processing functions of the reaping pre-processing section, namely, the planting culm raising function, the reaping function, and the reaping culm This results in the disadvantage that there is a possibility that the conveyance function etc. may be hindered.

In view of the above-mentioned circumstances, an object of the present invention is to avoid interfering with the reaping pre-processing function during reaping travel, while also preventing the reaping pre-processing section from contacting the ground etc. and being damaged when the machine turns. The goal is to prevent

A characteristic configuration of the present invention is that a grounding body that supports the reaping pre-processing unit in a floating state above the ground is disposed at a position forward of the traveling wheels, and that the grounding body is used when the machine is steered by the steering operation unit. The steering wheel is configured to be in a ground supporting position and to be in a non-ground supporting position when not being steered, so that the position can be freely switched in conjunction with the steering operation section.

The effects of the characteristic configuration of the present invention are as follows.

In other words, only when the steering operation unit is operated to turn the machine, the ground contact body automatically switches to a posture that supports the reaping pretreatment unit on the ground. In addition to preventing damage caused by direct contact, vertical vibrations caused by irregularities in the ground, stones, etc., are not transmitted to the pre-reaping treatment section through the ground contacting body during reaping travel.
Vertical vibrations do not interfere with the reaping pretreatment function.

Next, embodiments of the present invention will be described in detail based on the drawings.

A raising device 2 that raises two rows of planted culms in the field while dividing them one by one with the central weeding body 1, a reaping device 3 that reaps the raised culms, and a device that moves the cut culms to the rear of the machine. A transport device 4 transports the culm to one side of the fuselage, and a packer 5 transports the transported culm.
The reaping machine is equipped with a needle 6 and a knotting device 7 that converge in a converging space and drive intermittently to bundle a predetermined amount, and a discharge arm 8 that discharges the bundled culm bundle to the side of the fuselage. The pre-processing section is a -shaft two-wheel type running wheel 9a,
9b is connected to an axially mounted machine body, and a control handle 10 is provided on the machine body so as to be ejected rearward, and is used as a binder for continuously cutting and tying the planted culms in the field. .

\ The running wheels 9a and 9b each have a clutch lever 1, which is an example of a steering operation section provided on a steering handle 10.
1a and llb are configured to independently intermittent driving, and thus the steering operation is performed using the speed difference between the two wheels 9a and 9b.

On the frame 12 of the weeding body 1, an idle shaft 13 deflected to the left with respect to the forward direction of the aircraft is pivotally supported to be able to swing up and down as shown in FIG.
In conjunction with the cutoff of drive to the left wheel 9a by 11a, the wire 14 is reversibly changed from a non-grounding state to a grounding state.
are connected to each other, so that it is possible to turn with a constant radius of curvature defined by the idler wheels 13 and the driven right wheel 9b.

As shown in FIG. 4, the idler wheels 13 are configured to be in a non-grounding state where they are retracted inside the aircraft when traveling straight, and are in a grounding state where they protrude downward from the aircraft only when turning. As the idler wheel 13 protrudes, the front of the aircraft body is lifted up, and the idler wheel 13 and the traveling wheels 9a, 9b
The machine is configured to support the aircraft by automatically positioning the reaping device 3, etc., which tend to get in the way of turning when turning, above the ground, and supporting the entire aircraft without requiring any effort from the operator. The structure is such that it can be easily steered.

FIG. 5 shows another embodiment of a -row cutting binder, which is attached to the weeding body frame 15 on the side opposite to the exit side of the bundled culm bundles with the idle wheels 13 in the same manner as in the previous embodiment. It is.

Generally, as shown in Figure 6, binders always rotate in a predetermined direction to harvest and bind the planted culms in the field without releasing the bundled culm bundles to the uncut side. In order to achieve this goal, a method is adopted in which a predetermined width necessary for the machine to run at both ends of the field is cut in advance, and the cutting operation is carried out from outside to inward in a direction perpendicular to this cut area. Therefore, the idle wheels 13 are fixed in a predetermined direction, but depending on the applied model other than the binder, the idle wheels in different directions may be in contact with the ground in conjunction with the driving on/off of the traveling wheels 9a and 9b. Alternatively, one free wheel may be configured to be in contact with the ground in different directions.

In addition, it is not limited to the idler wheels 13, but may be a simple plate, for example, as long as it determines the turning center position of the machine body by soil resistance when it is in contact with the ground. It may be of any type as long as it can be obtained, various structural modifications are possible, and it is collectively referred to as the grounding body 3.

The grounding body 13 may be provided not only at the front of the aircraft but also at the rear of the aircraft.

In addition, a detection device is provided to detect contact with the planted culms, and based on the detection, the device automatically follows the row of planted culms, and turns without detecting the planted culms. It would be even more convenient to apply the present invention to a binder configured to automatically detect the turning timing, and to configure the binder to automatically cut off the drive of one wheel 9a based on the detection of the turning timing.
