Each support plate 56 is formed with a hole 57.

  Further, the front end of a longitudinally attached mounting arm (arm stop member) 58 is fixed to two locations on the rear surface of the cylindrical member 55, and these two mounting arms 58 are connected to the cylindrical member 55. They are positioned parallel to each other in a state of protruding rearward from the rear surface. Each mounting arm 58 has a shape in which the rear end side is divided into two forks, and has a closed state arm portion 59 and an open state arm portion 60 on the rear end side. A hole 45 is formed.

  The inner rear cover member 42 a has a rectangular cover plate 61 that covers the left rear portion of the embankment body 3. The cover plate 61 is positioned along the vertical surface when the inner rear cover member 42a is closed, and is positioned along the front, rear, and lower inclined surfaces that are inclined with respect to the vertical direction when the inner rear cover member 42a is opened. .

  Further, an outer side plate (center side plate) 62 is fixed to the outer end portion, which is the right end portion of the cover plate 61, in a state of being orthogonal to the cover plate 61 and protruding rearward from the cover plate 61. An inner side plate 63 is fixed to the inner end portion, which is the left end portion of the cover plate 61, in a state of being orthogonal to the cover plate 61 and protruding forward and rearward from the cover plate 61.

  The inner side plate 63 is positioned in the vicinity of the inner side of the left opposing side plate 46 of the cover body 41, and the inner side plate 63 and the left opposing side plate 46 partially overlap each other in a side view. . For example, even when the inner rear cover member 42a is in an open state, the front end portion of the inner side plate 63 and the rear end portion of the left opposing side plate 46 overlap each other in a side view.

  Similar to the inner rear cover member 42a, the outer rear cover member 42b has a rectangular cover plate 71 that covers the left rear portion of the embankment 3. The cover plate 71 is positioned along the vertical surface when the outer rear cover member 42b is closed, and is positioned along the front, rear, and lower inclined surfaces that are inclined with respect to the vertical direction when the outer rear cover member 42b is opened. .

  Further, a substantially triangular outer side plate 72 is fixed to the outer end portion which is the right end portion of the cover plate 71 in a state of being orthogonal to the cover plate 71 and protruding rearward from the cover plate 71. An inner side plate (center side plate) 73 is fixed to the inner end portion which is the left end portion of the cover plate 71 in a state of being orthogonal to the cover plate 71 and protruding rearward from the cover plate 61. The inner side plate 73 of the outer rear cover member 42b and the outer side plate 62 of the inner rear cover member 42a are formed in the same shape and are arranged close to each other.

  Further, holes (not shown) are formed in the upper end portions of the side plates 62, 63, 72, 73 of the inner rear cover member 42a and the outer rear cover member 42b. A support bolt 65 is inserted into a hole portion of the outer side plate 72 of the outer rear cover member 42b and a corresponding hole portion 57 of the outer support plate 56, and a nut 66 is screwed to the shaft portion of the support bolt 65. . Support bolts 65 are inserted through holes in the inner side plate 73 of the outer rear cover member 42b, holes in the outer side plate 62 of the inner rear cover member 42a, and holes 57 in the corresponding central support plate 56. A nut 66 is screwed onto the shaft portion of the bolt 65. Further, a support bolt 65 is inserted into the hole portion of the inner side plate 63 of the inner rear cover member 42a and the corresponding hole portion 57 of the inner support plate 56, and the shaft portion of the support bolt 65 holds the embankment body of the movable machine frame 15. The threaded hole portion (not shown) of the chain case of the portion 21 is screwed. For example, as with the outer side plate 62, a nut 66 may be screwed onto the shaft portion of the support bolt 65.

  Thus, the inner rear cover member 42a and the outer rear cover member 42b are supported by the three support bolts 65 so as to be rotatable about the rotation center axis X. The rotation center axis X is a line passing through the axis of the shaft portion of the support bolt 65. For example, the rear cover members (rear cover portions) 42a and 42b may be rotatably supported only by the support rod attached to the movable machine frame 15.

  In addition, a mounting member 76 having a mountain shape in the left-right direction is fixed to the rear surface of the lower end of each cover plate 61, 71. A substantially triangular projecting plate 77 is fixed to the center of the mounting member 76 in the left-right direction so as to project upward. Between the protruding plate 77 and the mounting arm 58, an arm 81 that is a round bar-like fixing longitudinal member is detachably mounted.

  In other words, the inner arm 81 for fixing the inner rear cover member 42a to the cover main body 41 in the closed state and the open state has a lower end portion of the inner arm 81 on the protruding plate 77 of the inner rear cover member 42a. The upper end of the inner attachment arm 58 is detachably attached to a selected one of the closed arm portion 59 and the open arm portion 60 via a pin 83 in the left-right direction. It is attached. That is, the inner rear cover member 42a can be selectively switched between a closed state and an open state by changing the mounting position of the upper end portion of the inner arm 81.

  Similarly, the outer arm 81 for fixing the outer rear cover member 42b to the cover main body 41 in the closed state and the open state has a lower end portion that is a left-right pin on the protruding plate 77 of the outer rear cover member 42b. 82 is detachably attached via 82, and its upper end is attachable / detachable via a pin 83 in the left-right direction to a selected one of the closed arm 59 and the open arm 60 of the outer mounting arm 58. Is attached. That is, the outer rear cover member 42b can be selectively switched between the closed state and the open state by changing the mounting position of the upper end portion of the outer arm 81.

  The arm 81, the left and right pins 82 and 83, and the R pin 84 that can be inserted into and removed from the holes of the pins 82 and 83 constitute a fixing means 43. Further, the rear cover portion 42, the fixing means 43, and the attaching means 50 constitute soil amount adjusting means 85 capable of adjusting the amount of soil (filling) supplied from the embankment body cover 6 side to the ridge forming body 4 side. Has been.

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

  When the coater 1 is moved in the advancing direction by traveling of the tractor in a state where the coater 1 is connected to the rear part of the tractor, the embankment body 3 is rotated in a predetermined direction and the soil of the paddy field and the main fence is cultivated. The cultivated soil is raised as a fill on the main fence, and the ridge forming body 4 is rotated in a predetermined direction at the rear side to compact the fill to form a new ridge.

  Here, normally, as shown in FIG. 8 (a), both the inner rear cover member 42a and the outer rear cover member 42b are closed, and the glazing operation is performed.

  At this time, most of the soil cultivated by the embankment claws 27 of the embankment body 3 is discharged rearward from the discharge port 40 of the embankment body cover 6 and supplied to the ridge forming body 4 side.

  However, the amount of soil supplied to the ridge forming body 4 side may be excessive depending on, for example, the soil quality of the paddy field and the former fence.

  In such a case, for example, as shown in FIG. 8 (b), the worker opens one of the inner rear cover member 42a and the outer rear cover member 42b, for example, the outer rear cover member 42b. On the other hand, for example, by closing the inner rear cover member 42a, the volume in the embankment cover 6 is slightly increased, and the filling operation is performed. Conversely, the inner rear cover member 42a may be opened and the outer rear cover member 42b may be closed.

  At this time, a part of the soil cultivated by the embankment claws 27 of the embankment body 3 is discharged to the rear from the soil escape space 39 below the outer rear cover member 42b in the open state and is released. As a result, the amount of soil supplied from the discharge port 40 of the embankment cover 6 to the ridge forming body 4 side is reduced.

  Still, when the amount of soil flowing from the embankment body cover 6 side to the ridge forming body 4 side is large, in order to further reduce the amount of soil, the operator, for example, as shown in FIG. Both the member 42a and the outer rear cover member 42b are rotated rearward to be switched and fixed to the open state, and the glazing operation is performed.

  And according to this paddy coater 1, since the back cover part 42 of the embankment body cover 6 can be selectively switched between a closed state in which the soil does not escape backward and an open state in which the soil escapes backward, It is possible to adjust the amount of soil supplied from the embankment body cover 6 side to the culvert formation body 4 side, and thus it is possible to prevent the amount of soil supplied to the culvert formation body side from being excessive and to perform appropriate culling work. .

  The back cover portion 42 of the embankment body cover 6 includes a plurality of rear cover members 42a and 42b arranged in the left-right direction, and each of the plurality of rear cover members 42a and 42b is individually in a closed state and an open state. Since it can be switched, the amount of soil supplied from the embankment body cover 6 side to the paddle forming body 4 side can be adjusted appropriately, and a more appropriate padding operation can be performed.

  Further, since the rear cover members 42a and 42b of the rear cover portion 42 are provided on the left side of the rear portion of the upper plate 48 of the cover main body portion 41 so as to be pivotable in the front-rear direction, the rear cover members 42a and 42b are rotated. By fixing with the fixing means 43, the rear cover members 42a and 42b can be easily switched to a desired state.

  In the first embodiment, the configuration in which the fixing means 43 has the fixing arm 81 has been described. However, for example, instead of the arm 81, the rear cover portion 42 is urged forward and fixed in the closed state. A gas spring, which is a biasing means that can be expanded and contracted, may be used.

  In the configuration using the gas spring, for example, even if a foreign object such as a stone enters between the rear cover portion 42 in the closed state and the embankment claw 27 of the embankment body 3, the rear cover portion 42 acts as an urging force of the gas spring. The foreign object can be escaped backward by turning backward and then being opened. The biasing means may be a coil spring, a rubber damper or the like other than the gas spring.

  Further, for example, as in the second embodiment shown in FIG. 9, the fixing means 43 may include a telescopic rod 91. The extension rod 91 is composed of an outer pipe 93 in which a pin hole 92 is formed, and an inner pipe 95 in which a plurality of adjustment holes 94 arranged in a straight line are formed to enter and exit the outer pipe 93. . The rear cover 42 can be selectively switched between a closed state and an open state (a plurality of open states with different inclination angles) by changing the adjustment hole 94 into which a fixing pin (not shown) is inserted.

  Furthermore, for example, as in the third embodiment shown in FIG. 10, a configuration using only the fixing pin 96 as the fixing means 43 may be used. In the case of this configuration, a pin hole (not shown) is formed in the upper portion of the side surface of the rear cover portion 42, and a plurality of adjustment holes 97 arranged on an arc centering on the rotation center axis X are formed in the support plate 56. ing. The rear cover 42 can be selectively switched between a closed state and an open state (a plurality of open states with different inclination angles) by changing the adjustment hole 97 into which the fixing pin 96 is inserted.

  In any of the embodiments, the number of open states of the rear cover part 42 is arbitrary. For example, in order to finely adjust the amount of soil, a plurality of open states of the rear cover part 42 can be set in stages. It is preferable to make it.

  Further, the rear cover part 42 is not limited to a structure constituted by a plurality of (or three or more) rear cover members (rear cover part constituting members) divided and arranged in the left-right direction. The cover member 42a and the outer rear cover member 42b may be configured as a single rear cover member. The rear cover portion 42 is not limited to metal, and may be made of elastically deformable rubber or resin.

  Further, the rear cover portion 42 is not limited to one that is closed and opened by rotation (rotational movement) with respect to the cover main body portion 41. For example, the rear cover portion 42 is translated parallel to the cover main body portion 41 in the vertical direction or the horizontal direction. It may be a closed state and an open state.

  Further, for example, a motor that is a driving unit that rotates the rear cover part 42 may be provided, and the state of the rear cover part 42 may be switched by operating the motor with a remote control unit.

  It should be noted that the configurations of the respective embodiments and the respective modifications can be appropriately combined without departing from the gist of the present invention.
