Each movable machine frame 35 is detachably engaged with the output rotator 27 of the power transmission means 13 and receives power from the input shaft 11 from the output rotator 27 while driving and rotating in a predetermined direction. A rotary-type tillage body (rotary) 36 for plowing work is rotatably provided. That is, the cultivating body 36 that rotates by receiving power from the input shaft 11 side and is supported by the movable machine frame 35 is rotatably supported by the movable machine frame 35, and the upper side of the cultivated body 36 is covered by the cover portion of the movable machine frame 35. The movable machine frame 35 has a cover function for the cultivating body 36.
[0027]

That is, for example, the inner end portion of the reinforcing connection pipe portion 43 of the movable machine frame 35 on the right side in the traveling direction and the inner end portion of the reinforcing connection pipe portion 43 of the movable machine frame 35 on the left side in the traveling direction are the transmission case 12 of the stationary machine frame 3. They are connected to each other via one machine frame common shaft 31 attached to the rear surface portion 18 via a shaft support member 15. The substantially cylindrical inner end portion of the reinforcing connecting pipe portion 43 of the right movable machine frame 35 is rotatably connected to the rear portion of the machine frame common shaft 31, and is substantially the same as the reinforcing connecting pipe portion 43 of the left movable machine frame 35. A cylindrical inner end portion is rotatably connected to a front portion of the machine frame common shaft 31. The reinforcing connecting pipe portion 43 is formed on the front end portion of the movable machine frame 35 over substantially the entire length of the front end portion.
[0031]
The pair of left and right second leveling bodies 40 are connected to each other via a single leveling body common shaft 32 common to each of the pair of left and right second leveling bodies 40.
[0032]
That is, for example, the inner end portion of the second leveling body 40 on the right side in the traveling direction and the inner end portion of the second leveling body 40 on the left side in the traveling direction are connected to each other via a single leveling body common shaft 32. . Leveling into a hole in the U-shaped portion 44 formed at the inner end of the right second leveling body 40 and a hole in the U-shaped portion 44 formed at the inner end of the left second leveling body 40 The body common shaft 32 is inserted.
[0033]
When the machine frame common shaft 31 between the two movable machine frames 35 and the leveling body common shaft 32 between the two second leveling bodies 40 are positioned on a substantially straight line (rotation center axis X), manual operation can be performed. Accordingly, the left and right movable machine frames 35 and the second leveling body 40 rotate about the machine frame common shaft 31 and the leveling body common shaft 32, respectively, so that the pair of left and right tillage leveling means 4 are substantially V-shaped. Can be switched between a folding non-working state and a substantially straight horizontal unfolding working state. A gas spring 45 is provided between the fixed machine frame 3 and the movable machine frame 35 in order to facilitate human manual operation.
[0034]
On the other hand, as shown in FIG. 6, the farm work machine 1 includes a single leveling body operating means 51 that can set a pair of left and right second leveling bodies 40 to a free state and a locked state all at once.
[0035]
The leveling body operating means 51 is disposed between the horizontal center of the fixed machine frame 3 and the leveling body common shaft 32. That is, the upper end portion of the leveling body operating means 51 is connected to the substantially central portion in the left-right direction of the stationary machine frame 3, and the lower end portion of the leveling body operating means 51 is connected to the leveling body common shaft 32.
[0036]
The leveling body operating means 51 has, for example, a first connecting arm 53, and a lower end portion of the first connecting arm 53 is rotatably connected to a connecting member 54 via a support shaft 55 in the left-right direction. ing. The connecting member 54 is fitted on the outer peripheral side of the leveling body common shaft 32 so as to be rotatable in the circumferential direction of the leveling body common shaft 32.
[0037]
The upper end portion of the first connecting arm 53 is rotatably connected to the rear end portion of the second connecting arm 56 via a support shaft 57 in the left-right direction. The second connecting arm 56 is rotatably connected to a substantially central portion in the left-right direction of the stationary machine frame 3 via a support shaft 58 in the left-right direction. An engaging pin 59 in the left-right direction is provided at the intermediate portion of the second connecting arm 56. The engaging pin 59 can be engaged and disengaged with respect to the engaging groove 62 of the operating lever 61 provided at a substantially central portion in the left-right direction of the stationary machine frame 3 so as to be rotatable around a turning shaft 60 in the left-right direction. It has become.
[0038]
Then, the engagement between the engagement groove 62 and the engagement pin 59 is released based on the forward rotation operation of the operation lever 61 on the upper end side of the leveling body operating means 51, and the pair of left and right second leveling bodies 40 are left. Are simultaneously set in a free state in which the rotary shaft 41 can rotate up and down around the rotation shaft 41 (solid line in FIG. 6). The second leveling body 40 set in this free state is in a substantially horizontal posture and follows the ground leveling work while touching the surface of the field.
[0039]
Further, the engaging groove 62 and the engaging pin 59 are engaged with each other based on the backward rotation operation of the operation lever 61, and the pair of left and right second leveling bodies 40 are collectively centered on the rotation shaft 41. It is set to a locked state of a substantially standing posture that cannot be vertically rotated (two-dot chain line in FIG. 6).
[0040]
As shown in FIG. 1, the angle α formed by the line Z along the lower edge of the outer plate 35a of the movable frame 35 of the tilling means 4 and the rotation center axis X is, for example, an angle of 0 to 55 °. It is. The lower edge portion of the outer plate 35a moves while touching the field surface along the field surface during work. Further, the separation distance between the rotation center axis R and the rotation center axis X of the tillage body 36 is, for example, 30 to 50 cm.
[0041]
Next, the operation and the like of the above embodiment will be described.
[0042]
When plowing and leveling work (for example, plowing work or earthing work) is performed using the farm work machine 1, after the farm work machine 1 is connected to the rear part of the tractor, the stand device 21 is removed from the stand holder 22 of the fixed machine frame 3.
[0043]
Next, if the pair of left and right tillage leveling means 4 are in a non-folding state, the pair of left and right tillage leveling means 4 is positioned substantially coaxially after the folding fixing means 23 is unlocked. By rotating downward about the inclined machine frame common shaft 31 and the leveling body common shaft 32, the operation state is switched to a substantially straight horizontal deployment work state. When the tillage leveling means 4 is in the unfolding work state, the inner end portion of the tillage body 36 and the output rotating body 27 are engaged with each other so that power is transmitted.
[0044]
When the farm machine 1 is moved forward by the traveling of the tractor, the tilling work is performed by the rotating tiller 36 with the power from the output rotating bodies 27 of the both tillage leveling means 4 in the unfolded working state, and the first The leveling work is performed by the leveling body 37 and the second leveling body 40 in the free state.
[0045]
In addition, when performing earthing work on the shore of a farm or the like, the pair of left and right second leveling bodies 40 cannot be rotated up and down by rotating the operation lever 61 of the leveling body operating means 51 backward. Set to locked state.
[0046]
Further, for example, when the agricultural machine 1 is transported to a warehouse after the completion of the tilling work, etc., before the deployment fixing means 24 is unlocked, both the pair of left and right tilling ground means 4 are positioned substantially on the same axis. By switching upward about the inclined machine frame common shaft 31 and the leveling body common shaft 32, the state is switched to a substantially V-shaped folding non-working state.
[0047]
When the both tillage leveling means 4 rotate upward and switch to a substantially V-shaped folding non-working state, the length in the left-right direction of the whole farming machine 1 (the width of the whole farming machine 1) is the same as before folding. Since the amount of protrusion of the farm work machine 1 to the side of the tractor is reduced to less than half, traveling safety can be easily ensured, and the farm work machine 1 can be easily transported.
[0048]
In this way, according to the agricultural machine 1 of the above-described embodiment, the rotation center axis X common to each of them, that is, each of the machine frame common shaft 31 and the leveling body common shaft 32, for example, is provided. By turning upwards around the center, it is switched to a substantially V-shaped folding non-working state projecting obliquely upward from the stationary machine frame 3, and one common rotation center axis X, that is, for example, A pair of left and right tillage leveling means 4 which are switched to a substantially straight horizontal unfolding operation state projecting laterally from the fixed machine frame 3 by rotating downward about one machine frame common shaft 31 and a leveling body common shaft 32. Therefore, the number of parts such as shaft members can be reduced compared to the conventional configuration in which both tillage leveling means rotate around two separate rotation center axes corresponding to each other. Can be simplified and lightweight It can be achieved, the manufacturing cost can be reduced.
[0049]
Further, the pair of left and right tillage leveling means 4 can be prevented from coming into contact with the cabin of the tractor during the upward rotation, and the front and rear weight balance and the left and right weight balance can be improved. Since each means 4 is rotated upward and switched to a substantially V-shaped folding non-working state, the rear view from the tractor can be easily secured.
[0050]
Furthermore, by operating the operating lever 61 of the leveling body operating means 51 whose lower end is connected to the leveling body common shaft 32, the pair of left and right second leveling bodies 40 can be reliably set to the free state and the locked state all at once. Moreover, the backlash is reduced by reducing the number of parts, and the second leveling body 40 can be stabilized.
[0051]
Further, it is a rotation center of a pair of left and right movable machine frames 35 that support a cultivating body 36 that rotates in a predetermined direction and performs a cultivating work and a first grading body 37 that performs a grading work at a rear position of the cultivating body 36. Since one machine frame common shaft 31 is attached to the rear surface portion 18 of the substantially box-shaped transmission case 12 so as to be positioned behind the transmission case 12, the configuration is simple and the assembly work can be facilitated. The manufacturing cost can be reduced, and the periphery of the transmission case 12 can be easily made compact.
[0052]
Furthermore, the agricultural machine 1 can easily cope with various tractors only by exchanging the shaft support members 15 and 15a and the transmission cases 28 and 28a, and other components can be shared. That is, for example, by replacing the shaft support member 15a and the transmission case 28a corresponding to a standard three-point link tractor or by replacing the shaft support member 15 and the transmission case 28 corresponding to a special three-point link tractor with 3 It is possible to easily cope with various tractors having different work machine connection parts such as a point link part or a two-point hitch part. Further, for example, when the top mast 5 and the lower arm 6 are recombined and dealt with, there is a problem that the front / rear balance of the tractor at the time of folding the agricultural machine 1 is deteriorated, but the shaft support members 15, 15a and the transmission cases 28, 28a. Such recombination does not cause such problems.
[0053]
The farm work machine 1 can also be of a left and right three-division type having a soil working part made up of a tillage body, a first leveling body, a second leveling body, and the like at a substantially central part in the left-right direction.
[0054]
Further, the tilling leveling means 4 is not limited to one in which the first leveling body 37 is provided via the rubber plate 38 at the rear end portion of the movable machine frame 35 having a cover function. The first leveling body 37 may be provided directly at the rear end.
[0055]
Further, the agricultural working machine 1 is centered on a common shaft member (for example, the machine frame common shaft 31) that is a common folding center axis for the pair of left and right tillage leveling means that do not have the second leveling body 40. It is also possible to switch between the folding non-working state and the unfolding working state by turning.
[0056]
Moreover, the agricultural working machine 1 is limited to the one provided with a pair of left and right tillage leveling means 4 that can be switched between the folding non-working state and the unfolding working state by turning up and down around one turning center axis X. Instead, a pair of left and right tillage leveling means 4 that can be switched between the folding non-working state and the unfolding working state by turning back and forth about one turning center axis X in the substantially vertical direction may be provided.
[0057]
Furthermore, the farm work machine 1 may be provided with a pair of left and right tillage leveling means that can be switched between a folding non-working state and an unfolding working state by turning around two turning central axes parallel to each other. The pair of left and right movable machine frames 35 may be switchable between a folding non-working state and a unfolding working state by rotation about separate folding center axes.
[0058]
Further, the folding central axis (machine frame common shaft 31), which is the rotation center of the movable machine frame 35, is positioned above the transmission case 12 on the upper surface of the substantially box-shaped transmission case 12 via the shaft support member 15. You may attach as follows. Further, the folding center shaft may be directly attached to the rear surface portion or the upper surface portion of the transmission case 12 without using the shaft support member 15.
[0059]
On the other hand, for example, a transmission case 28 that rotatably supports an output rotating body 27 that outputs power from the input shaft 11 side is provided with various tractors (for example, a tractor having a standard three-point link and a tractor having a special three-point link). ) By changing the direction (reversing mounting). For example, if a transmission case 28 attached corresponding to a special three-point link tractor is mounted upside down on the lower surface portion 17 of the mission case 12, it can correspond to a standard three-point link tractor. That is, in this case, the shaft support members 15 and 15a corresponding to a traveling vehicle such as a tractor are replaced, and the direction of the transmission case 28 corresponding to the plurality of types is made to correspond to the traveling vehicle. It is possible to easily cope with various traveling vehicles having different machine connecting portions.
[0060]
In addition, various tractors are not limited to those that can handle standard three-point link tractors and special three-point link tractors. For example, one special three-point link (ordinary special three-point link) tractor and one special three-point link tractor It may be compatible with a tractor of another special three-point link (rare special three-point link) different from the three-point link.
[0061]
In other words, for example, a conventional farming machine dedicated to a special three-point link, for example, a work harrow (a part that cannot share parts and cannot be recombined) is used for a tractor with a rare special three-point link. There was a problem that the posture was tilted forward and the rake floated up when it was shallowly scraped, so that proper leveling work could not be performed. In this embodiment, various changes can be made only by replacing the shaft support members 15 and 15a and the transmission cases 28 and 28a. The tractor can be easily handled, and such a problem does not occur.
[0062]
【The invention's effect】
According to the invention 請 Motomeko 1, whereby with replacing the shaft support member corresponding to the vehicle corresponding to the vehicle the direction of the transmission case, for example, various working machine connection part such as a three-point link section are different from the running It can be easily adapted to cars.
