Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicator of a residual culm processing machine for treating residual culm left on a ridge after harvesting a cultivated crop. There are culms.

[0002]

2. Description of the Related Art A remaining culm processing machine for cutting a remaining culm has an engine, a motor and the like for transmitting the cutter shaft mounted above a cutter frame on which a cutter shaft is vertically mounted.

[0003]

In a work mode in which a remaining culm processing device is mounted in front of a tractor vehicle body to cut the remaining culm while traveling on the vehicle body, vibration and noise of an engine or the like that transmits a cutter shaft are used. For example, it may be difficult to determine whether the cutter shaft is being rotated, whether the remaining stem is clogged, or the like. Further, even if an observation window is provided in the cutter case that covers the cutter chamber, the inner surface is easily stained by frictional contact with the remaining culm or the like, and it is difficult to confirm the rotation state of the cutter shaft.

[0004]

According to the first aspect of the present invention, a vertical cutter shaft 2 on which a cutting blade 1 is disposed is mounted on a vehicle body 3.
In the remaining culm processing machine which cuts the remaining plant culm 4 while running while being attached to the front of the car, a viewing window 6 which can recognize the rotation of the cutter shaft 2 is provided in the transmission case 5 above the cutter shaft 2. The configuration of the indicator is characterized in that: An invention according to claim 2 is a residual culm processing machine that cuts the remaining planting culm 4 while running while attaching a vertical cutter shaft 2 on which a cutting blade 1 is disposed in front of a vehicle body 3. A rotating body 9 is provided on the upper side of the transmission case 5 above the shaft 2 with a cover 8 having a viewing window 7 and rotated in conjunction with the cutter shaft 2.

[0005]

According to the first aspect of the present invention, when cutting the remaining culm 4 while rotating the cutter shaft 2 and running along the four remaining culms, the upper part of the cutter shaft 2 is cut. The rotation state of the cutter shaft 2 can be recognized from the viewing window 6 of the transmission case 5. For this reason, since the viewing window 6 is provided in the transmission case 5 which is separated from the cutter chamber where the remaining culm 4 is cut, there is no dirt due to scattering of the remaining culm and the rotation state of the cutter shaft 2. Can be accurately recognized for a long time. In addition, since the viewing window 6 uses the transmission case 5, the configuration can be simplified. The invention according to claim 2 recognizes the rotation state of the internal rotating body 9 from the viewing window 7 of the cover 8 above the transmission case 5 and determines the rotation state of the cutter shaft 2. Since the cover 8 where the body 9 is located is separated from the transmission case 5 and the cutter room, etc., it is possible to eliminate dirt due to scattering of lubricating oil, remaining culm, etc., and to accurately recognize the rotation state of the rotating body 9. In addition, the mounting structure of the rotating body 9 and the cover 8 can be simplified.

Embodiments of the present invention will be described with reference to the drawings. In FIG. 1 to FIG.
Has a cutting blade 1 disposed on a cutter shaft 2 mounted on a cutter frame 11 and a receiving blade 13 disposed on a receiving blade frame 12 opposed thereto, and the cutter shaft 2 is placed on the cutter frame 11. By being driven by the mounted engine 14, the remaining culm 4 planted on the ridge surface A between the cutting blade 1 and the receiving blade 13 is guided to perform a short cutting process. The remaining culm processing device 10 is mounted via a hitch 16 on the front side of a tractor vehicle body 15 in a riding four-wheel running mode. 17 is the front wheel, 1
8 is a rear wheel, 19 is a driver's seat, 20 is a steering wheel, 21 is an engine mounted in a hood 22, 23 is a lift link on the rear side of the vehicle body 15, and a rotary tilling device 24.
Can be attached and lowered. While the tractor body 15 can be driven by the drive of the engine 21, the cultivating claw 26 of the cultivating device 24 is rotated by transmitting the PTO shaft 25, and the remaining culm processing device 10 cuts the remaining culm 4 shortly. Then, the remaining 27 parts of the ridge A are plowed. The cut piece 28 cut short from the planting residual culm 4 is diffused to the ridge surface A on the rear side of the residual culm processing device 10.

The remaining culm processing apparatus 10 comprises a transmission case 29 on the upper part of the cutter frame 11 and a bearing arm 30 on the lower part.
Between the upper and lower ends of the cutter shaft 2. The cutting blade 1 is mounted around disks 31 arranged at appropriate intervals along the cutter shaft 2. 180 for each disk 31
The cutting blades 1 for every two sheets are arranged in the rotation phase of
As shown in FIG. 4, they are arranged in such a manner that the rotation angle is sequentially delayed from the upper cutting edge 1 to the lower cutting edge 1 under the same rotation phase angle. The fixed receiving blade 13 is brought close to the rotational position of the cutting blade 1 in each stage, and the receiving blade 3 is attached to the receiving frame 12.
2 attached. Because the cutter shaft 2 is inclined forward, when the remaining plant culm 4 is guided and cut, the cutter shaft 2 is guided from the upper end of the remaining culm row 4 to be cut first. Moreover, since the cutting blade 1 of the cutter shaft 2 acts on the receiving blade 13 with a delay from the upper part to the lower part, the remaining culm 4 is sequentially cut from the upper end to the lower end. Therefore, the remaining culm 4
Since the total length of the culm does not act on the cutting blades 1 of each stage at the same time, the variation in cutting resistance is small and a smooth cutting can be performed.

The engine 14 is mounted on the upper end of the cutter frame 11 via transmission cases 29 and 5. In the transmission case 5, the drum 3 rotated via the drum clutch 33 from the engine shaft of the engine 14 is provided.
4, and thereby an integrally rotating output shaft 35 is mounted. The rotation is transmitted from the lower end of the output shaft 35 to the upper end of the cutter shaft 2 via a gear 36 in a transmission case 29. The transmission case 5 that covers the outer periphery of the drum 24 is provided with two viewing windows 6 at the rear side, and can be monitored from the back of the driver's seat 19. The viewing window 6 can be in the form of a hole, but can also be in a closed form by providing a transparent resin cover, a glass cover, or the like. A coloring mark 37 is formed on the rotating peripheral surface of the drum 34 with a heat-resistant paint. When the clutch 33 is engaged by driving the engine 14, the drum 34 and the output shaft 35 are rotated to transmit the cutter shaft 2, and the rotation of the drum 34 allows the rotational coloring of the mark 37 to be monitored from the viewing window 6. You can see the rotation status. Reference numeral 38 denotes a boss for bearing the output shaft 35.

A cutter chamber 3 in which the cutter shaft 2 is mounted.
The left and right sides of 9 are covered with a side cover 40, and the rear side is covered with a rear cover 41. A viewing window 42 is formed in the upper part of the rear cover 41, so that the inside of the remaining culm can be viewed from behind. The viewing window 42 is provided with a transparent resin cover. A lifting handle 43 moves the cutter frame 11 up and down with respect to the hitch 16 so that the cutting position can be adjusted to the culm height of the remaining culm 4 on the ridge surface A. Reference numeral 44 denotes a remaining culm guide that projects to the front side of the cutter frame 11.

[0010] The body 3 is propelled along the standing ridges of the remaining culm 4, the cutter shaft 2 is driven by the drive of the engine 14 to cut the remaining culm 4, and the remaining culm 4 is rotated by the rotation of the cutting blade 1. 4 is cut at the upper end first and then cut at the lower end sequentially. The rotation status of the cutter shaft 2 is determined by the driver's seat 1
9 can be monitored while seated. Since the viewing window 42 is formed in the upper rear part of the cutter frame 11,
Through the viewing window 42, the cutter shaft 2 in the cutter chamber 39
And the cutting processing status by the cutting blade 1 can be seen through. When the viewing window 42 becomes dirty due to the cutting process of the remaining culm 4 and becomes difficult to see through, the rotation status of the internal mark 37 can be monitored from the viewing window 6 of the transmission case 5 above the cutter frame 11. Since the viewing window 6 is configured such that the clutch drum 34 is rotated in the transmission case 5 and the bearing boss 38 of the output shaft 35 is provided, there is no adhesion of dust due to the processing of the remaining culm 4 as in the cutter chamber 39. Rotating mark 37
Also, the dirt on the viewing window 6 and the like is small, and the monitoring of the mark 37 can be maintained satisfactorily for a long time. If the rotation speed of the cutter shaft 2 is reduced or stopped due to excessive load, etc., the engine 1
4, the clutch 33 is disengaged and the drum 3
4 is not rotated, the state of the cutter shaft 2 can be determined by observing the rotational state of the mark 37.

Next, the points different from the above example will be described with reference to FIG. A cylindrical cover 8 is provided on the upper part of the transmission case 29.
To cover the rotating body that rotates inside. The viewing window 7 is provided at a position higher than the rear engine 14 at the upper end of the cover 8, so that the rotation status of the internal rotating body 9 can be monitored from the rear driver's seat 19 side. The rotating body 9 has a coloring mark like the mark 37 of the previous example, and is attached to the rotating shaft 45. The rotary shaft 45 is supported in the cover 8 but has a socket 46 at the lower end. The rotary shaft 45 is fitted on a square shaft portion 47 formed at the upper end of the cutter shaft 2 to rotate integrally.

When the cutter shaft 2 is rotated by the driving of the engine 14, the rotating shaft 45 and the rotating body 9 connected thereto are rotated, so that the rotating state can be seen from the viewing window 7 of the cover 8. In this embodiment, since the inside of the cover 8 is partitioned from the transmission case 29, there is no scattering of lubricating oil or the like, and the rotating body 9, the viewing window 7 and the like are not stained. Moreover, since the indicator including the rotating body 9 and the cover 8 can be easily attached and detached from the outside, the configuration is also simplified.
