An embodiment of a plastering machine according to the present invention will be described with reference to the drawings.

In FIG. 1 to FIG. 4, reference numeral 1 denotes a hull coater , and this hull coater 1 is a tow type that is used by being mounted on a tractor T that is a traveling vehicle. The padding machine 1 is a padding machine that performs padding work (soil work) in the soil working unit 5 while moving the farm field in the traveling direction (X direction in the drawing) by traveling of the tractor T during work.

The plastering machine 1 is connected to a fixed machine frame 2 via two rotary arm bodies having different lengths, that is, a first rotary arm body 3 and a second rotary arm body 4. A movable machine frame 6 that supports the earth working unit 5 is provided.

  The longer first rotating arm body 3 is substantially hollow and serves also as a transmission case (chain case). One end of the first rotating arm body 3 has a vertical axis 11 attached to the stationary machine frame 2. The other end side of the first rotating arm body 3 is rotatably connected to the movable machine frame 6 via a vertical shaft 12.

  The shorter second rotary arm body 4 is a simple bowl-shaped one, and one end side of the second rotary arm body 4 can be rotated about the fixed machine frame 2 via a vertical shaft 13. The other end side of the second rotating arm body 4 is connected to the movable machine frame 6 via a vertical shaft 14 so as to be rotatable.

  The movable machine frame 6 has a plurality of, for example, a plurality of earth work portions 5 that perform a smearing operation (earth work) based on the forward traveling of the tractor T by the rotation of the two rotating arm bodies 3 and 4 having different lengths. Two forward work positions (see FIGS. 1 and 2), one reverse work position (see FIG. 4) in which the earth work unit 5 performs the scouring work (earth work) based on the backward travel of the tractor T, and the earth The working unit 5 moves to one storage non-working position (see FIG. 3) located behind the tractor T. That is, the movable machine frame 6 is centered on the shafts 11 and 13 while the first and second rotary arm bodies 3 and 4 are connected to the fixed machine frame 2 and the movable machine frame 6, respectively. By pivoting substantially along the horizontal direction, it selectively moves to four positions.

  1 is a position where the protruding amount (offset amount) of one side (right side) of the earth working unit 5 with respect to the tractor (rear wheel) T is small, and the forward work position in FIG. The position is a position where the amount of protrusion of the earth working unit 5 toward one side (right side) with respect to the tractor T is large.

  Further, the two rotating arm bodies 3 and 4 having different lengths are parallel in a plan view when the movable machine frame 6 is located at the forward working position, and are flat when the movable machine frame 6 is located at the backward working position. It will be crossed by sight. In addition, when the movable machine frame 6 moves from the forward work position in FIG. 1 to the forward work position in FIG. 2 (or vice versa), both the rotating arm bodies 3 and 4 are temporarily parallel to each other in the middle thereof. (Parallel in the strict sense).

  Further, both the rotating arm bodies 3 and 4 do not need to be disconnected from the machine frames 2 and 6 when the movable machine frame 6 is moved from the forward operation position to the backward operation position. The earth working unit 5, that is, a later-described embankment body 23, the ridge forming body 24, and the culvert upper surface processing body 30 are supported by the two rotary arm bodies 3 and 4 via the movable machine frame 6.

  Here, the fixed machine frame 2 has a three-point connecting portion 16 that is a traveling vehicle connecting portion that is connected to a three-point link portion (not shown) that is a working machine lifting portion of the tractor T. The three-point connecting portion 16 is composed of one top mast 18 having a top pin 17 attached to the tip portion and two left and right lower arms 20 having a lower pin 19 attached to the tip portion.

  Further, the fixed machine frame 2 has an input shaft holding portion (gear box) 21, and an input shaft (not shown) for inputting power from the tractor T is rotatably held by the input shaft holding portion 21. ing. The PTO shaft of the tractor T is connected to the input shaft via a universal joint, a transmission shaft, and the like.

  The movable machine frame 6 supports a rotatable embankment (rotary) 23 that cultivates and raises the padding soil on the front side in the traveling direction, and is positioned behind the embankment 23 on the rear side in the traveling direction. Then, the padding soil that has been raised in the embankment body 23 is compacted so as to be pushed into the main paddle, and a rotatable paddle forming body (disk) 24 is formed to form an inclined paddle inner surface and a horizontal paddle upper surface. And the heel upper surface treatment body 30 that is located forward of the embankment body 23 in the traveling direction and pretreats the heel upper surface. That is, the earth working part 5 constituted by the embankment body 23, the dredger forming body 24, and the dredge upper surface treating body 30 is supported by a movable movable machine frame 6, and the earth working part 5 is composed of both rotating arm bodies. 3 and 4 move together with the movable machine frame 6 based on the rotation of both the rotating arm bodies 3 and 4 while being supported by the movable body frame 4.

  The embankment 23 is composed of, for example, a rotary shaft 25 and a plurality of tilling claws 26 attached radially to the rotary shaft 25. Further, the ridge forming body 24 is composed of, for example, a rotating shaft 27, a substantially truncated cone side surface forming member 28 attached to the rotating shaft 27, a substantially cylindrical upper surface forming member 29 attached to the rotating shaft 27, and the like. It is configured. Further, like the embankment body 23, the culvert upper surface processing body 30 is configured by, for example, a rotary shaft 25, a plurality of tilling claws 26 attached radially to the rotary shaft 25, and the like.

  All of the embankment body 23, the ridge forming body 24, and the heel surface treating body 30 receive power from the input shaft via a power transmission means (not shown) and rotate in a predetermined direction. The power transmission means is constituted by a sprocket, a chain or the like disposed in the first rotating arm body 3 which also serves as a transmission case.

On the other hand, the dredge coater 1 moves the movable machine frame 6 together with the earth work section (the embankment body 23, the dredge forming body 24, and the dredge upper surface treatment body 30), two forward work positions, one reverse work position, and one storage. Single drive means 31 for moving to a non-working position is provided.

  The single drive means 31 is constituted by a hydraulic cylinder (hydraulic cylinder) 32 which is, for example, one extendable / contractible means.

  The cylinder 32 has a cylinder body 33, and a rod 34 is attached to the cylinder body 33 so as to be able to advance and retract. The distal end portion of the rod 34 is rotatably connected to a rotating body 37 that is rotatably attached to the stationary machine frame 2 via a vertical shaft 36. That is, the distal end side of the cylinder 32 is rotatably connected to the rotating body 37, and the proximal end side of the cylinder 32 is rotatably connected to the stationary machine frame 2.

  Then, by the rotation of the rotating body 37 based on the expansion and contraction operation of the cylinder 32, the two rotating arm bodies 3 and 4 having different lengths are rotated, and the movable machine frame 6 is earthed along with this rotation. It automatically moves to each position together with the working unit 5. For example, when the movable machine frame 6 moves from the forward work position to the reverse work position, or vice versa, the earth work section 5 rotates 180 degrees, and the embankment body 23, the ridge formation body 24, and the heel upper surface treatment body 30. Before and after are reversed.

Further, the wrinkle coater 1 stores the forward lock means 41 that locks the movable machine frame 6 in each forward work position, the backward lock means 42 that locks the movable machine frame 6 in the backward work position, and the movable machine frame 6 is not stored. Storage lock means 43 for locking to the work position is provided.

  The locking and unlocking of the movable machine frame 6 by the locking means 41, 42, 43 does not require any manual locking operation and unlocking operation, and automatically based on the expansion / contraction operation of one cylinder 32. To be done.

  The forward lock means 41 includes, for example, a hook 46, an engagement pin 47 that engages with and disengages from the hook 46, and the like. The reverse lock means 42 includes, for example, a hook 49, an engagement pin 50 that engages with and disengages from the hook 49, a pin presser 48 that presses the engagement pin 50, and the like. The storage lock means 43 includes a hole 51 formed in the rotating body 37, an engagement pin 52 that engages with the hole 51, and the like. Reference numeral 45 denotes auxiliary lock means for assisting the storage lock means 43.

Next, the operation and the like of the wrinkle coater 1 will be described.

  At the time of forward work in which the filling body 23, the ridge forming body 24, and the heel upper surface processing body 30 perform the glazing operation by the forward traveling of the tractor T, for example, the movable body frame 6 is moved by the contraction operation of the cylinder 32 constituting the single drive means 31. The embankment body 23, the ridge forming body 24, and the heel upper surface processing body 30 are set in a predetermined forward operation state (see FIGS. 1 and 2).

Then, when the tractor T is moved forward in a state in which the embankment body 23, the ridge forming body 24, and the ridge upper surface processing body 30 are set in a predetermined forward operation state, the ridge coating machine 1 moves in the traveling direction (forward). The power from the tractor T is input from the input shaft and transmitted to the embankment body 23, the ridge formation body 24, and the heel surface treatment body 30 through the power transmission means, and the embankment body 23, the ridge formation body 24, and the heel surface treatment. The body 30 rotates.

  Then, the upper surface of the old paddy is pretreated with the padded surface processing body 30, and the soil for paddy coating is cultivated with the embankment body 23 and raised to the main paddle. It is compacted at 24, and a strong new newspaper that does not collapse easily is formed.

  Further, at the time of retraction work (return work) in which the filling work is performed by the embankment body 23, the reed formation body 24 and the reed upper surface treatment body 30 by retreating the tractor T at the end portion of the field so that there is no unpainted portion, For example, the movable machine frame 6 is locked at the retracting work position by the extending operation of the cylinder 32, and the embankment body 23, the ridge forming body 24, and the heel surface treating body 30 are set in a predetermined retracting work state (see FIG. 4).

Then, when the tractor T is moved backward in a state in which the embankment body 23, the ridge forming body 24, and the ridge upper surface processing body 30 are set in a predetermined backward operation state, the ridge coating machine 1 moves in the traveling direction (rearward). As with the forward operation, the upper surface of the old paddle is pre-treated with the pad surface processing body 30, and the padding soil is cultivated with the embankment body 23 and raised to the main bar, and the upper bar is raised. The formed soil is compacted by the cocoon forming body 24, and a strong new cocoon that does not easily collapse is formed.

Further, during non-working, such as during transporting the padding machine 1 to a storage location such as a warehouse, the movable machine frame 6 is locked at the storage non-working position, and the embankment body 23, the paddle forming body 24, and the paddle top surface processing body 30 are locked. Is set to a predetermined storage non-working state (see FIG. 3).

At this time, the embankment body 23, the ridge forming body 24, and the heel surface processing body 30 are located behind the tractor T in a state of being close to the fixed machine frame 2 and stored in the rear region of the tractor T. Thus, balance is a relatively good before and after the tractor T, and the embankment member 23, since the rib forming member 24 and ridge top surface treating body 30 does not protrude either to the tractor T sideward, transportation of ridge painted machine 1 Can be done safely.

And, according to the above-described plastering machine 1, since the two rotating arm bodies 3, 4 having different lengths are installed between the fixed machine frame 2 and the movable machine frame 6, the parallel links having the same length are provided. In addition, the configuration can be easily simplified as compared with a conventional coater having a connecting frame and a transmission frame.

  Further, since the first rotating arm body 3 also serves as a transmission case for accommodating a part of the power transmission means for transmitting power to the earth working unit 5, the number of parts is reduced accordingly, and the configuration is further simplified. Can be

  Furthermore, since there are a plurality of, for example, two forward work positions at which the earth work unit 5 performs the smearing work based on the forward travel of the tractor T, the size of the tractor T can be appropriately handled.

  In addition, since the movable machine frame 6 can be moved to each position together with the earth working unit 5 by the power from the single drive means 31, that is, the cylinder 32, and can be locked and unlocked at each position, The simplification of the configuration can be further facilitated.

  Further, when moving the movable machine frame 6 from the forward work position to the backward work position, for example, it is not necessary to release the connection between both the rotating arm bodies 3 and 4 and the machine frames 2 and 6. Therefore, the troublesomeness at the time of switching to the reverse working state can be eliminated, and the switching of the working state can be easily performed.

The number of pre-advance working position may be three or more, or may be singular.

Further, the single drive means 31 is not limited to one extendable cylinder 32, and may be one motor or the like .
