Description

[Detailed Description of the Invention] The present invention relates to a reaping and harvesting machine having a movable cutting rod.

In the case of the above-mentioned reaping and harvesting machine, in general, when the degree of lodging of the planted stem culms is large, since the stem culms are heavily intertwined, the weeding rod is used to loosen the entanglement and separate the weeds. If the work is carried out while driving and the degree of lodging of the planted stem culms is relatively small, it is better to prevent the stems from shedding by minimizing entanglement of the stem culms and not giving unnecessary vibrations to the stem culms. The work is carried out with the weeding rod drive stopped because it is preferable from the viewpoint of this. However, in the past, the weeding rod had to be driven and stopped manually, which resulted in the disadvantage that it was time-consuming and there was a risk of erroneous operation.

The object of the present invention is to enable the use of dividing rods to be used according to the degree of lodging of planted stem culms without error and without special effort.

In the above-mentioned reaping/harvesting machine, the present invention provides a control mechanism for automatically intermittent driving of the weeding rod based on the detected result of the machine running speed when the detected result of the machine running speed is below a set value. The present invention is characterized in that the weeding rod is provided in a swinging state.

In other words, in general, when the degree of lodging of the planted stem culms is large, the work is carried out at a slow machine speed in order to prevent the cutting of ears due to severe entanglement of the stem culms. When the degree of lodging of the planted stem culms is small, the work is carried out by increasing the traveling speed of the machine in order to increase efficiency, because there is little entanglement of the stem culms and it is difficult for ears to break due to raising. Therefore, the degree of lodging of the planted stem culms can be controlled by automatically driving the weeding rod when the vehicle is running at high speed and automatically stopping the drive when the vehicle is running at low speed. In addition to being able to properly use the dividing rod in the driving state and in the stopped state according to the size of the grass,
This eliminates the need for special switching, and changes the degree of lodging of the planted stem culms, allowing for smooth weeding and efficient work while preventing losses due to shedding. It became like that.

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

As shown in FIG. 1, a driving unit 2 and a control handle 3 are provided at the rear of a running machine having a pair of left and right wheels 1, 1, and a planting stem culm is installed at the front of the running machine. A pair of left and right lifting devices 4,
4. A reaping device 5 that reaps the drawn stem culms, an endless rotating belt-like body 6 that transports the cut stem culms from the rear of the pulling devices 4 and 4 to one side of the machine body, and a stem culm from this belt-like body 6 A binding device 7 is attached for tying up a certain amount of the wafer and discharging it toward the lateral outside of the machine body, thereby forming a binder.

As shown in FIG. 2, the left side of the pair of left and right stem culm introduction paths r, r along the longitudinal direction of the machine body equipped with the lifting devices 4, 4 corresponds to the upper side for conveying the belt-shaped body 6. On the side and on the side, and the lifting device 4
First and second weeding rods 8 and 9 for dividing the planted stem culm into objects to be reaped and objects not to be reaped are placed at a location in front of the culm, both of which act together. In an inclined state where the terminal side is located at a higher level, and the first
While the action starting end of the weeding rod 8 is pulled up and pivotally connected to the weeding body 10 fixedly installed at the lower end of the device so as to be able to swing up and down, the action starting end of the second weeding rod 9 is then It is provided in a state in which it is swingably connected to the grass division body 10 by a ball joint.

As shown in FIG. 3, the other end of the push-pull rod 11, whose one end is pivotally connected to the free end of the first branching rod 8, is attached to the rotating arm 13 attached to the machine frame 12. The rotation shaft 16 is pivotally connected to the free end side, and is connected between the rotation support shaft 14 of the rotation arm 13 and the driving shaft 16 which is interlocked with the transmission transmission M for the wheel 1 via the transmission case 15. A clutch 20 is provided, which is configured to engage and disengage a gear 17 integrally rotatably and slidably attached to the support shaft 14 with the gear 18 of the driving shaft 16, and is biased to a disengaged state by a spring 19. , the free end side of the second branching rod 9 and the middle of the push/pull rod 11 are connected by a branching rod side link 21 and a rod side link 22, and the dividing rod side link 21 is connected to a holder 2.
3 are slidably held by a bending/extending link mechanism, so that the first dividing rod 8 can be driven to swing up and down, and the second dividing rod 9 can be driven to swing from side to side. By disengaging the clutch 20, the driving of both the branching rods 8 and 9 can be stopped. The clutch 20, the first sliding operating shaft 24 for switching the transmission M between the first forward speed and the second forward speed, and the second sliding operating shaft 25 for switching the transmission between the third forward speed and the reverse speed. A swinging lever 26 whose free end is inserted into the locus of movement of only the first sliding operating shaft 24, and an operating wire in which this lever 26 and the swinging operating member 27 of the clutch 20 are interlocked and connected. 28
Based on the detection result of the aircraft traveling speed, the driving of both the dividing rods 8 and 9 is automatically intermittent, and both dividing rods 8 and 9 are driven only when the aircraft traveling speed is the first forward speed. A control mechanism 29 is configured for this purpose. That is, when the transmission M is operated to the first forward speed transmission state, the lever 26 is pressed and swung by the first operation shaft 24, the clutch 20 is brought into the engaged state, and the transmission M is moved to the forward first speed. When the transmission state other than 1st speed or the neutral state is operated, the lever 26 is swung toward the transmission side by the spring 19 of the clutch 20, and the clutch 20 is switched to the disengaged state. Therefore, when the aircraft is running in the first forward speed, the splitter rods 8 and 9 are driven, and whether the aircraft is running in the second forward speed, the third forward speed, or is stopped. Alternatively, when the vehicle is moved backward, the drive of the splitter rods 8 and 9 is automatically stopped.

The control mechanism 29 detects the traveling speed of the aircraft based on the rotational speed of the wheels in addition to the transmission state of the mission M, and controls the clutch 20 based on the detection result.
It is also possible to adopt a configuration in which the switch is operated by an electric or hydraulic drive mechanism.

Incidentally, the arc-shaped long hole of the holder 23 shown in FIG. 3 can be adjusted so that the swinging direction of the second divider rod 9 is tilted horizontally or at a higher level toward the outside of the fuselage by changing the mounting posture of the holder. It is for changing direction.
