In other words, this attachment 1 is detachably attached to the horizontal rotary shaft 3 of the ridge coating machine 2 in place of the ridge forming body 10 for forming new ridges (see FIGS. 6(a) to 6(c)).

The ridge coating machine 2 is in a normal state in which the ridge forming body 10 is attached to the rotary shaft 3 (the state shown in FIG. 6(a)). In its normal state, the ridge coating machine 2 is connected to the rear part of a tractor (not shown), which is a traveling vehicle. do. Further, at the corner of the field, the ridge coating machine 2 is switched from the forward work state to the return work state, and then moves backward (in the direction of travel) in the return work state by traveling backward of the tractor to perform the ridge coating work. .

The ridge coating work by the ridge coating machine 2 in the normal state is a ridge restoration work for forming a strong new ridge that does not collapse by repairing the original ridge with cracks, mole holes, etc. before watering the field (paddy field). However, at that time, the soil of the field (soil on the surface of the field) is added to the original ridge, so if the ridge coating work is repeated every year, the ridge will become thicker in the width direction and higher in height. The ridge will be larger than necessary. The attachment 1 is used to restore the enlarged ridge to the desired size.

The ridge coating machine 2 in a normal state comprises a body 6 which is detachably connected to a three-point link at the rear of the tractor, and which rotates in a predetermined direction to plow the paddy field (farm field) and the original ridge to produce the soil (cultivation). An embankment body (plowing section) 7 for heaping up soil) on the original ridge, a ridge formation body (disk section) 10 for compacting the embankment (plowed soil) by the embankment body 7 while rotating in a predetermined direction to form a new ridge, A top surface scraping body (top surface scraping unit) 8 is provided for scraping the top surface of the base ridge while rotating in a predetermined direction.

The embankment body 7, top scraping body 8 and ridge forming body 10 are covered with cover bodies 11, 12 and 13, respectively. The cover body 13 covers a part of the ridge side surface forming part 31 of the ridge forming body 10, and a part of the attachment 1 is covered by the cover body 13 when the attachment 1 is used.

The ridge forming body 10 is mounted on the rotating shaft 3 and driven to rotate in a predetermined direction together with the rotating shaft 3 based on the power from the input shaft (not shown). Because it is also fast, it slips and rotates against the ridge.

Even when the attachment 1 is attached to the rotating shaft 3, the rotational force (power) of the rotating shaft 3 is not transmitted to the attachment body 41. It is driven to rotate in a predetermined direction based on the force of That is, the non-driving attachment body 41 does not receive power from the rotating shaft 3 side of the ridge coating machine 2, and is grounded on the ridge and is driven along the ridge while rotating as the tractor travels (moves). to move.

The machine body 6 has a machine frame 16 that is detachably connected to a three-point linkage (not shown) at the rear of the tractor. An input shaft (not shown) is rotatably provided on the machine frame 16, and the PTO shaft of the tractor is connected to this input shaft via a joint.

Then, based on the power (driving force) input from the input shaft, the embankment body 7, the top scraping body 8 and the ridge forming body 10 are driven and rotated to perform the work. A working section 20 is composed of the embankment body 7, the top scraping body 8 and the ridge forming body 10. As shown in FIG. However, when the attachment 1 is used, the working section 20 is composed of the embankment body 7, the top scraping body 8 and the attachment 1.

A movable machine frame 17 is connected to the machine frame 16 via a connecting means 18, and the movable machine frame 17 is provided with a working unit 20. As shown in FIG. By expanding and contracting the cylinders 21 and 22, which are expansion and contraction drive means, the movable machine frame 17 is moved and the position of the working part 20 is changed, so that the ridge coating machine 2 can be brought into the desired state (forward working state, retracted state, and return working state). ). Further, the movable machine frame 17 is provided with a gauge wheel (direction wheel) 23 that runs in contact with the paddy field.

The embankment body 7 has a rotating shaft 26 that rotates forward and backward based on power from the input shaft side, and a plurality of plowing tines 27 for embankment are attached to the rotating shaft 26 . Like the embankment body 7, the top scraping body 8 also has a longitudinally rotating shaft 28 driven to rotate based on the power from the input shaft side. installed.

The ridge forming body 10 has a ridge side forming portion 31 having a truncated cone shape (including a substantially truncated cone shape; the same shall apply hereinafter) that compacts the embankment by the embankment body 7 to form an inclined side surface (ridge side surface) of the new ridge. A cylindrical shape (including a substantially cylindrical shape) that is provided at the end of the ridge side forming part 31 on the diameter reduction side and compacts the embankment by the embankment body 7 to form the horizontal surface of the new ridge (ridge top surface) The same applies hereinafter) and a ridge top forming portion 32 (see FIG. 7(f)). The end of the ridge top surface forming portion 32 on the side of the ridge side forming portion 31 is in the shape of a truncated cone, and this truncated cone-shaped end forms the sloped shoulder surface (ridge shoulder surface) of the new ridge. be done.

The ridge side forming part 31 has a plurality of ridge side forming plates 33 that form the ridge side by compacting the embankment so as to push it in on the rear side in the rotation direction. A plurality of ridge side forming plates 33 are arranged in the rotational direction, and a linear step portion 34 is formed between both ridge side forming plates 33 adjacent to each other in the rotational direction. A plurality of spiral stepped portions 35 are formed on the outer peripheral surface of the ridge top surface forming portion 32 . The embankment is strongly compacted by the action of these stepped portions 34 and 35, and a strong new ridge that is resistant to collapse is formed. The ridge side forming portion 31 has a cylindrical mounting portion (not shown) on the rotation center side, and this mounting portion is detachably attached directly to the outer peripheral side of the rotating shaft 3 .

2 and 3, for example, the attachment 1 is formed to have substantially the same shape and size as the ridge forming body 10, and instead of the ridge forming body 10, the ridge coating machine 2 is detachably attached to the rotary shaft 3 and used.

Here, regardless of the driving rotation of the rotating shaft 3 based on the power from the input shaft side, the attachment 1 is arranged to rotate the horizontal rotation center axis X in the left-right direction with respect to the rotating shaft 3 based on the force from the ridge side. A non-driven attachment body 41 that loosely solidifies the embankment by the embankment body 7 while rotating about the center in a predetermined direction to form a temporary ridge, and can be attached and detached to the outer surface (grounding surface) of this attachment body 41 by attachment means 43. A soil adhesion preventive body 42 is attached to prevent soil from adhering to the outer surface of the attachment body 41. - 特許庁

The temporary ridge formed by the non-driven attachment main body 41 is a ridge formed prior to the formation of the new ridge, and is different from the strong new ridge formed by the driven ridge forming body 10. , the surface soil is soft and crumbles more easily than new ridges.

The attachment body (driven rotating body) 41 includes a truncated cone-shaped side surface forming portion 46 that loosely solidifies the embankment by the embankment body 7 to form the inclined surface-shaped side surface of the temporary ridge, and the diameter reduction side of the side surface forming portion 46. It has a cylindrical upper surface forming part 47 which is provided at the end and loosely solidifies the embankment by the embankment body 7 to form the horizontal upper surface of the temporary ridge.

The truncated cone-shaped outer peripheral surface of the side surface forming portion 46 is covered with a plurality of plate-like first soil adhesion prevention members 51 arranged in the rotation direction, and the cylindrical surface-shaped outer peripheral surface of the upper surface forming portion 47 The surface is covered with a plurality of plate-like second soil adhesion prevention members 52 arranged in the direction of rotation. The first soil adhesion prevention member 51 and the second soil adhesion prevention member 52 constitute the soil adhesion prevention body 42 .

Each soil adhesion prevention member (for example, soil adhesion prevention plate which is an elastic body) 51 and 52 is made of a material to which soil hardly adheres, and is elastically deformable such as a rubber plate, a resin plate, or a metal plate. . The soil adhesion prevention members 51 and 52 are detachably attached to the outer surface of the attachment body 41 (the outer peripheral surface of the side surface forming portion 46 and the outer peripheral surface of the upper surface forming portion 47) at the front ends in the rotation direction by the mounting means 43. The soil adhesion preventing members 51 and 52 are arranged such that the ones adjacent to each other in the direction of rotation partially overlap each other, but the overlapping portions may not be present.

In the illustrated example, the entire outer peripheral surface of the side surface forming portion 46 and the entire outer peripheral surface of the upper surface forming portion 47 are covered with the soil adhesion preventing body 42, but for example, only a part of the outer peripheral surface is covered with an elastic member or the like. Alternatively, for example, the outer surface of the attachment main body 41 may be exposed without the soil adhesion prevention body 42 . Further, in the illustrated example, the soil adhesion prevention member is attached to the attachment body at the front end in the rotation direction, but for example, the soil adhesion prevention member is attached to the attachment body at the rotation direction front end and the rotation direction intermediate portion. It's okay.

Further, the attachment main body 41 is configured so that when the ridge coating machine 2 is used while the attachment 1 is attached to the rotating shaft 3 (during temporary ridge formation work), the traveling direction of the ridge coating machine 2 is adjusted based on the travel of the tractor. It has a securing means 55 for securing straightness of movement to.

The securing means 55 is positioned at the inner end (left end) of the attachment body 41 in the left-right direction, and has an annular and plate-like second end that is inserted so that its outer peripheral end penetrates into the surface of the field. A circle positioned at the inner plate 56, which is one insertion portion, and the outer end (right end), which is the other end in the left-right direction of the attachment body 41, and is inserted so that the outer peripheral end penetrates the upper surface of the temporary ridge. It has an outer plate 57 which is an annular plate-shaped second insertion portion. That is, the securing means 55 is composed of two inner plates 56 and an outer plate 57 having different sizes.

The inner plate 56 is provided at the inner end portion of the side surface forming portion 46, and the outer peripheral end portion of the inner plate 56 protrudes radially outward from the inner end portion of the side surface forming portion 46. As shown in FIG. In other words, the inner plate 56 has an annular insertion plate portion 56a that is inserted into the paddy surface of the field at its outer peripheral end. A circular opening 58 is formed in the inner plate 56 .

The insertion plate portion 56a of the inner plate 56 is formed with a plurality of mounting holes 54 arranged at intervals in the circumferential direction. This mounting hole 54 includes a diameter expanding member (not shown) that is inserted deeper into the paddy surface than the insertion plate portion 56a, an extended soil adhesion preventing member (not shown) that prevents soil from adhering to the insertion plate portion 56a, and the like. to the inner plate 56.

The outer plate 57 is provided at the outer end portion of the upper surface forming portion 47 opposite to the side surface forming portion 46 side. projects radially outward from the In other words, the outer plate 57 has an annular insertion plate portion 57a that is inserted into the upper surface of the temporary ridge at its outer peripheral end.

A circular opening 59 is formed in the outer plate 57, and the opening 59 is closed by a lid 60 so as to be openable and closable. This lid 60 is detachably attached to the outer plate 57 by attachment means 50 .

Furthermore, as shown in FIG. 3, the attachment main body 41 has a cylindrical attachment portion (boss) 61 provided at the outer end portion (right end portion) of the side forming portion 46 . The attachment portion 61 is detachably attached to the outer peripheral side of the rotating shaft 3 by attachment means 62 via a bearing (bearing member) 63 and an inner boss (cylindrical member) 64 . The bearing 63 and the inner boss 64 constitute blocking means 65 for blocking transmission of power (rotational force) from the rotating shaft 3 to the attachment body 41 .

In other words, the attachment main body 41 is rotatably attached to the rotating shaft 3 via a blocking means (bearing means) 65 for blocking power transmission. In short, the attachment portion 61 of the attachment main body 41 is detachable and rotatable with respect to the rotating shaft 3 .

And unlike the mounting portion (not shown) of the ridge forming body 10 on the rotation center side, the power from the rotating shaft 3 is not transmitted to the attachment portion 61 on the rotation center side of the attachment main body 41 . For this reason, unlike the ridge forming body 10, the attachment main body 41 is not driven to rotate by the power from the rotating shaft 3, but is driven to rotate based on the force received from the grounded ridge side.

The mounting means 62 is composed of, for example, a bolt 66 that can be screwed into the female threaded portion 3a of the rotating shaft 3, a cylindrical collar 67, and a washer 68 through which the shaft portion 66a of the bolt 66 is inserted.

As shown in FIG. 4, by changing the position of the collar 67, which is a position adjusting member, the lateral position of the attachment body 41 with respect to the rotating shaft 3 can be changed. That is, the attachment main body 41 can be laterally adjusted with respect to the rotary shaft 3 of the ridge coating machine 2 .

On the other hand, the attachment main body 41 has a plurality of openings 71 for releasing a part of the embankment by the embankment body 7 (tilled soil plowed by the tillage claws 27) to the side opposite to the temporary ridge (inside the attachment main body 41). are doing.

That is, for example, the side forming portion 46 of the attachment main body 41 has a truncated conical plate-like member (base member) 72 in which a plurality of openings 71 for removing soil are formed. That is, the side surface forming portion 46 is composed of a plate-like member 72 having a truncated cone shape with a diameter decreasing toward the upper surface forming portion 47 and having a predetermined thickness. A plurality of shaped openings 71 are arranged side by side in the rotational direction at intervals. Each opening 71 is formed through the inner and outer surfaces of the portion of the side surface forming portion 46 on the side of the enlarged diameter end portion.

Soil that has entered between the outer surface of the side surface forming portion 46 (in other words, the outer surface of the plate member 72) and the inner surface of the first soil adhesion prevention member 51 passes through the opening 71 for releasing soil (for discharging soil). It passes through and escapes to the inner surface side (field surface side) of the side surface forming portion 46 . That is, the soil that has entered is discharged from the opening 71 formed in the side forming portion 46 .

Furthermore, the attachment main body 41 prevents (suppresses) the soil from the opening 71 for releasing soil, that is, the cultivated soil released to the inside of the attachment main body 41 by the opening 71 from going toward the rotating shaft 3 side. It has a guard portion 73 .

The guard portion 73 is composed of, for example, a plurality of guard plates 74 arranged in the rotational direction, and each guard plate 74 is fixed to the inner surface of the plate member 72 by welding or the like so as to cover the outer peripheral surface of the rotating shaft 3 . The plurality of guard plates 74 prevent soil that has entered the attachment body 41 through the opening 71 of the plate member 72 from entering the rotating shaft 3 .

Next, the operation and the like of the attachment 1 described above will be described.

First, referring to FIG. 5, the work procedure for adjusting the size of the ridge, that is, for example, returning the ridge that has become large due to repeated ridge painting to the desired size (returning to the desired size) ridge formation method) will be explained.

The operator first removes the ridge forming body 10 from the rotary shaft 3 of the existing ridge coating machine 2 and then attaches the attachment 1 to the rotary shaft 3 . That is, the ridge forming body 10 is replaced with the attachment 1 (step 1).

Next, using the ridge coating machine 2 with the attachment 1 attached to the rotating shaft 3, the embankment by the embankment body 7 is loosely consolidated with the attachment 1 to form a temporary ridge (step 2). That is, the upper surface of the original ridge is shaved by the top scraping body 8, the original ridge is plowed by the embankment body 7, and the embankment supplied by the embankment body 7 is loosely consolidated by the attachment 1 to form the temporary ridge.

Thereafter, after removing the attachment 1 from the rotating shaft 3 of the ridge coating machine 2, the ridge forming body 10 is attached to the rotating shaft 3. That is, the attachment 1 is replaced with the ridge forming body 10 (step 3).

Next, using the ridge coating machine 2 with the ridge forming body 10 attached to the rotating shaft 3, the embankment by the embankment body 7 is compacted by the ridge forming body 10 to form a new ridge (step 4). That is, the upper surface scraping body 8 scrapes the upper surface of the temporary ridge, the embankment body 7 plows the temporary ridge, and the embankment supplied by the embankment body 7 is compacted by the ridge forming body 10 to form a new ridge. As a result, the height and width of the ridges that have become large due to the repetition of the ridge coating work are reduced, and new ridges of the desired size are formed.

6 and 7, the operator first moves the ridge forming body from the rotary shaft 3 of the ridge coating machine 2, as shown in FIGS. 6(a) and 6(b). Remove 10. Next, as shown in FIG. 6(c), the attachment 1 is attached to the rotating shaft 3 of the ridge coating machine 2. Next, as shown in FIG.

Next, as shown in FIGS. 7(d) and (e), the ridge coating machine 2 with the attachment 1 attached to the rotating shaft 3 (the ridge coating machine with the attachment used) is moved back to the original ridge by running the tractor. When it is moved along the direction of travel, the embankment is loosely compacted by the attachment 1 to form a temporary ridge.

In other words, when the attachment body 41 is driven to rotate based on the force from the ridge side in a state in which it is in contact with the ridge via the soil adhesion preventing body 42, the embankment by the embankment body 7 is loosely compacted, and the soil on the surface is loosened. soft temporary ridges are formed.

At this time, since the inner plate 56 of the attachment body 41 is inserted into the paddy field and the outer plate 57 is inserted into the upper surface of the temporary ridge, the straightness of the straight movement of the attachment 1 along the ridge (the traveling direction of the entire ridge coating machine) straightness of movement to) is ensured. In this case, the rotating shaft 3 of the ridge coating machine 2 does not need to be driven. You can stop it.

During the temporary ridge formation (temporary ridge formation process), the height of the ridge coating machine 2 is stabilized by the grounded attachment 1 and the gauge wheel 23, respectively, so the relative height of the embankment body 7 with respect to the attachment 1 is adjusted. By doing so, it is possible to adjust the cutting depth (plowing depth) with respect to the original ridge. Similarly, by adjusting the relative height of the top scraping body 8 with respect to the attachment 1, the top scraping depth (plowing depth) with respect to the original ridge can also be adjusted.

Furthermore, by adjusting one or a plurality of soil volume adjusting means, it is possible to adjust the volume of soil for the temporary ridge that is pushed by the attachment 1 and loosely compacted (see FIG. 1).

Specifically, for example, by changing the degree of opening of the retaining plate 81 positioned behind the embankment body 7, the amount of soil released from the attachment 1 side to the paddy field side can be adjusted. Also, by changing the angle of the soil adjusting plate 83 in the side cover body 82 located on the outer side of the embankment body 7, the amount of soil released from the attachment 1 side to the opposite side of the field (outer side) can be adjusted. Furthermore, by changing the lateral position of the auxiliary cover 84 in the cover body 11 covering the embankment body 7, the amount of soil heaped up on the upper surface of the original ridge can be adjusted. Further, by changing the vertical position of the guard 85 in the cover body 11 covering the embankment body 7, the amount of soil released from the embankment body 7 side to the paddy field side can be adjusted.

After that, as shown in FIG. 7(f), after the attachment 1 is replaced with the ridge forming body 10, when the ridge coating work is performed using the ridge coating machine 2 in the normal state, the ridge forming body 10 A strong new ridge is formed that is reduced to the desired height and width.

At this time, a temporary ridge is plowed by the embankment body 7 and the top scraping body 8, but since the soil on the surface of this temporary ridge is soft, the embankment body 7 and the top scraping body 8 penetrate more deeply than in the normal case, Much soil is plowed and scraped. For this reason, the new ridge is smaller than the ridge that is enlarged by repeating the ridge painting work.

The work shown in FIG. 7(f) (new ridge formation work) may be performed immediately after the work (temporary ridge formation work) shown in FIG. 7(d), or after a predetermined period of time has elapsed. . For example, when it is carried out after a predetermined period of time has passed, the temporary ridge may partially collapse due to rainwater or the like, and the soil may be returned to the paddy side. Also, when forming a new ridge, the amount of soil for the new ridge can be adjusted in the same way as when forming a temporary ridge.

According to the attachment 1, a worker such as a farmer is provided with a non-driven attachment body 41 that forms temporary ridges while being driven to rotate based on the force from the ridge side around the rotary shaft 3. Since the enlarged ridge can be adjusted to a desired size by using the inexpensive attachment 1, there is no need to purchase a relatively expensive ridge cutting machine, which reduces the economic burden on workers. It is possible to reduce the burden of

In addition, since the attachment main body 41 is provided with the soil adhesion preventing body 42 for preventing the adhesion of soil to the attachment main body 41, the attachment main body 41 of the attachment can be properly prevented from being soiled during work. A worker's burden reduction can be aimed at.

Furthermore, since the attachment main body 41 has a truncated conical side surface forming portion 46 forming the side surface of the temporary ridge and a cylindrical upper surface forming portion 47 forming the upper surface of the temporary ridge, the attachment body 41 has a shape similar to a normal ridge. A temporary ridge is formed, and therefore, the working position is easily stabilized during the formation work of the new ridge, and the work can be easily performed by setting the desired amount of embankment (the amount of soil supplied to the ridge forming body 10). Also from this point, the burden on the operator can be reduced.

In addition, since the attachment main body 41 has an opening 71 for releasing a part of the soil plowed by the embankment body (tillage section) 7 to the side of the field opposite to the temporary ridge, for example, the embankment body 7 Even if a desired amount of soil cannot be released to the field side only by means for adjusting the amount of soil such as the shoring plate 81 and the guard 85 on the side, soil can be removed from the opening 71 of the side surface forming portion 46 of the attachment body 41. Since it can escape, it is possible to perform a suitable temporary ridge formation work, and furthermore, it is possible to prevent the problem of soil clogging between the outer surface (front surface) of the side surface forming part 46 and the inner surface (back surface) of the first soil adhesion prevention member 51. .

Furthermore, since the attachment main body 41 has a guard portion 73 that prevents the soil released from the opening 71 formed in the side forming portion 46 from going toward the rotating shaft 3, It is possible to appropriately prevent soil from adhering to the mounting portion 61, thus eliminating the need for labor such as soil removal, and reducing the burden on the operator.

The attachment 1 is not limited to the configuration described above, and may be configured as shown in FIGS. 8 and 9, for example.

In the attachment 1 shown in FIGS. 8 and 9, the side forming portion 46 of the attachment body 41 includes a plurality of longitudinal members (frames) 91 radially positioned about the rotation center axis X of the attachment body 41, and these members. It has a plurality of annular members (pipes) 92a and 92b which are connected and fixed to the plurality of longitudinal members 91 and which are positioned around the rotation center axis X and which are different in size from each other.

That is, the side surface forming portion 46 is composed of a plurality of elongated members 91 having a U-shaped cross section and a plurality of annular members 92a and 92b having a circular cross section so as to have a plurality of openings 71. A plurality of openings 71 for releasing soil are also formed in the side surface forming portion 46 . A guard plate 74 of a guard portion 73 is fixed to the elongated member 91 by welding or the like to prevent the soil from the opening 71 for escaping soil from going toward the rotating shaft 3 side.

Also, the attachment 1 shown in FIGS. 8 and 9 can achieve the same effects as the attachment 1 described above. In addition, for example, the longitudinal member 91 of the side surface forming portion 46 may be provided with a soil adhesion preventing member. Further, for example, a configuration in which the outer surface of the upper surface forming portion 47 is exposed without providing the soil adhesion prevention member 52 may be employed.

On the other hand, in each of the above-described embodiments, the attachment main body preferably has securing means for securing straightness, but may be configured without securing means. Further, for example, a member (inner plate 56, outer plate 57) that constitutes the securing means may be provided with a soil adhesion preventing member.

Furthermore, for example, the attachment body itself may be made of a material to which soil does not easily adhere, or at least only the portion (grounding surface) of the attachment body that contacts the ridge may be made of a material to which soil does not readily adhere. .

Also, the attachment replaceable (replaceable) with the ridge forming body may be composed only of an attachment main body that forms a temporary ridge while rotating with respect to the rotating part of the ridge coating machine based on the force from the ridge side.

Furthermore, in order to facilitate the attachment work of the attachment main body to the rotating part of the ridge coating machine, a restricting means (for example, a detachable pin, etc.) for restricting the rotation of the inner boss 64 with respect to the attachment part (boss) 61 during the attachment work is provided. may be provided.

Further, for example, a configuration in which the amount of opening of the opening for releasing soil in the attachment main body can be adjusted, or a configuration in which an opening/closing member capable of opening and closing the opening may be provided.

Furthermore, the attachment main body is not limited to a rotary type that forms a temporary ridge while being driven to rotate.

Although several embodiments and modifications thereof have been described, it is also possible to appropriately combine each embodiment and each modification without departing from the gist of the present invention.
