Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-cutting apparatus for a whole culm throwing combine, which is equipped with a scraping reel, a reaping device and a scraping device for laterally scraping the stalks.

[0002]

2. Description of the Related Art In an all-culm input type (normal type) combine, a take-in reel is provided to scrape the grain culm before cutting. Then, when the hand sown grain culm of the headland part is put into the platform of the pre-mowing treatment device in advance, the drive of the scraping reel and the slicing device is stopped, and the mowing grain is cut. It is designed to ensure the safety of workers who throw culms.

[0003]

By the way, in the prior art,
Since the clutch operating device for connecting and disconnecting the drive of the scraping reel and the reaping device is arranged substantially in the middle of the long platform to the left and right, there is a problem that it is difficult to open and close the clutch. . The present invention aims to solve such problems. Therefore, the present invention has taken the following technical means.

[0004]

That is, according to the present invention, there is provided a platform 23 having a scraping device 4 for laterally feeding and scraping a cut culm to the front part of a vehicle body equipped with a threshing device 1.
And a harvesting pretreatment device having a harvesting device 5 and a scraping reel 6 are mounted in a total culm throw-in type combiner, which is provided in a transmission device 7 of the scraping reel 6 and the harvesting device 5. An operating device 9 for connecting and disconnecting the clutch device 8 is provided, and the operating device 9 is provided on the outer surface side of the platform 23.

[0005]

Therefore, according to the present invention, when the hand-cut grain culm is put into the platform of the pre-cutting processing device, the scraping reel and the cutting device are operated by operating the clutch operating device. Since the drive is stopped, the safety of the operator who puts in the harvested culms can be ensured, but in particular, since the clutch operating device is provided on the outer side of the side surface of the platform, it does not rotate when operating the clutch. Since the worker does not have to approach the part to be worked, the safety of the work is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The threshing device 1 is mounted on a machine body 11 having a traveling device, and has a configuration for threshing an introduced grain culm. The grain culm feeding / conveying device 3 is provided such that its starting end faces the lower scraping device 4 and its trailing end faces the grain culm supply port 2 of the threshing device 1 described above.

The reaping device 5 is provided in front of the scraping device 4. Reference numeral 12 represents a weeding rod. The scraping reel 6 is rotatably mounted above the mowing device 5 so as to be rotatably driven so that the grain culms in the field can be scraped rearward. And take-in reel 6
Is an actuator 10, that is, a vertical cylinder-10.
By using a and the cylinder 10b in the front-rear direction, it is possible to adjust the movement in the up-down direction and the front-rear direction by hydraulic pressure.

Next, the hand operating device 9 is the harvesting device 5.
And clutch device 8 provided on transmission device 7 for take-up reel 6
It has a configuration that allows intermittent operation. The operating device 9 is provided on the outer surface of the platform 23 on the right side plate 23a side. The hand-operated operating device 9 is configured to operate the switch 13 in association with the above-described operation, and to switch the valves of the operating device 10 by operating the switch.

The valve switching structure will be described in a more specific manner with reference to FIG. Switches 14, 15, 16, 17
Is connected to a solenoid for switching the valve of the hydraulic circuit of the take-up reel 6, that is, an upper solenoid 18, a lower solenoid 19, a front solenoid 20, and a rear solenoid 21. 22 is a limit switch,
When the scraping reel 6 completes the retracting operation to a predetermined position o
It is set to ff.

Therefore, the scraping reel 6 can be retracted backward and upward when the hand operation device 9 is operated, after stopping the transmission and stopping. It should be noted that, regardless of the above-described embodiment, it may be configured such that when the hand operation device is operated, the scraping reel 6 can be moved only to either the upper side or the rear side. In the case of performing the manual handling work with the above configuration, first, the manual handling device 9
To operate. Then, the mowing device 5 and the scraping reel 6 are
The clutch device 8 in the transmission device 7 is disengaged and stopped.

At the same time, the take-in reel 6 is provided with the switch 1
When the upper solenoid 18 and the rear solenoid 21 are operated to operate the valve 3, the valves are switched and the vertical cylinder 10a is extended, and the front-rear cylinder 10a is extended.
b shrinks and retracts backward and upward. When the take-in reel 6 is retracted to a predetermined position, the limit switch 22 is turned off and the movement is stopped.

When the respective parts have been operated in this manner, the worker can easily supply the cutting culms to the rotation-driven scraping device 4 without being disturbed by the scraping reel 6. it can. In addition, 24 shows a driving cabin.
