It is a sectional view of the attachment same as the above. It is a sectional view after the position of the attachment same as the above is changed. It is a figure which shows the work procedure when adjusting the size of a ridge. (a) to (c) are explanatory diagrams for explaining the same work procedure as above. (d) to (f) are explanatory diagrams following FIG. 6. It is a sectional view of the attachment concerning other embodiments of the present invention. FIG. 7 is a sectional view of an attachment according to still another embodiment of the present invention.

An embodiment of the present invention will be described with reference to FIGS. 1 to 7.

1 to 4, 1 is an attachment (guide roller) for forming a temporary ridge, and this attachment 1 is detachably attached to a rotating shaft (drive rotating shaft) 3, which is a rotating part of a ridge coating machine 2. It is used. That is, this attachment 1 is removably attached to the left-right rotating 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 (the state shown in FIG. 6(a)) in which the ridge forming body 10 is attached to the rotating shaft 3. In its normal state, the ridge coating machine 2 is connected to the rear of a tractor (not shown), which is a traveling vehicle, and performs ridge coating while moving forward (in the traveling direction) in a forward working state as the tractor moves forward. do. In addition, in the corner of the field, the ridge coating machine 2 is switched from the forward work state to the return work state, and then performs the ridge painting work while moving backward (in the direction of travel) in the return work state due to the backward movement of the tractor. .

This ridge painting work by the ridge coating machine 2 in the normal state is a ridge repair work that repairs the original ridges with cracks, mole holes, etc. and forms strong new ridges that are difficult to collapse before water is applied to the field (paddy field). However, at this time, soil from the field (field soil) is added to the original ridges, so as the ridge painting work is repeated every year, the ridges become thicker in the width direction and taller, and as a result, The ridges become larger than necessary. The attachment 1 is used to return the enlarged ridge to the desired size.

The ridge coating machine 2 in a normal state has a machine body 6 that is detachably connected to a three-point link at the rear of a tractor, and rotates in a predetermined direction to plow the field (field area) and former ridges to remove the soil. An embankment body (cultivating part) 7 that heaps up soil on a ridge, a ridge forming body (disk part) 10 that compacts the embankment of the embankment body 7 while rotating in a predetermined direction to form a new ridge, and a ridge forming body (disc part) 10 that heaps up the soil on a ridge while rotating in a predetermined direction. It is provided with an upper surface scraping body (upper surface scraping part) 8 for scraping the upper surface of.

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

When the ridge forming body 10 is attached to the rotating shaft 3, it is driven to rotate in a predetermined direction together with the rotating shaft 3 based on the power from the input shaft side (not shown). However, since its peripheral speed is faster than the traveling speed of the tractor, it slips and rotates relative to the ridge.

Note that even when the attachment 1 is attached to the rotating shaft 3, the rotational force of the rotating shaft 3 is not transmitted to the attachment body 41, so the attachment body 41 is not affected by the force from the grounded ridge side. based on the rotation in a predetermined direction. In other words, the non-driven attachment main body 41 moves along the ridge while being driven to rotate as the tractor travels (moves) while being in contact with the ridge.

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

Then, based on the power (driving force) inputted by the input shaft, the embankment body 7, the upper surface scraping body 8, and the ridge forming body 10 are driven to rotate, respectively, to perform the work. A working section 20 is constituted by the embankment body 7, the upper surface scraping body 8, and the ridge forming body 10. However, when the attachment 1 is used, the working section 20 is constituted by the embankment body 7, the top surface scraping body 8, and the attachment 1.

Further, a movable machine frame 17 is connected to the machine frame 16 via a connecting means 18, and a working section 20 is provided on this movable machine frame 17. The movable machine frame 17 moves by the expansion and contraction of the cylinders 21 and 22, which are the expansion and contraction drive means, and the working part 20 changes its position, so that the ridge coating machine 2 is brought into the desired state (forward working state, retracted state, and return working state). ) can be selectively switched to Furthermore, the movable machine frame 17 is provided with a gauge wheel (direction wheel) 23 that runs while touching the rice field.

The embankment body 7 has a rotation shaft 26 in the longitudinal direction that is driven and rotated based on power from the input shaft side, and a plurality of tilling claws 27 for embankment are attached to this rotation shaft 26. Similar to the embankment body 7, the top surface scraping body 8 also has a rotation shaft 28 in the longitudinal direction that is driven and rotated based on the power from the input shaft side, and this rotation shaft 28 has a plurality of tilling claws 29 for scraping the top surface. installed.

The ridge forming body 10 has a truncated cone-shaped (including approximately truncated cone-shaped; the same applies below) ridge side forming part 31 that compacts the soil from the embankment body 7 to form the sloping side (ridge side) of the new ridge, and a cylindrical (including approximately cylindrical; the same applies below) ridge top surface forming part 32 that is provided at the narrowing end of the ridge side forming part 31 and compacts the soil from the embankment body 7 to form the horizontal top surface (ridge top) of the new ridge (see Figure 7(f)). The end of the ridge top surface forming part 32 on the ridge side forming part 31 side is truncated cone-shaped, and this truncated cone-shaped end forms the sloping shoulder surface (ridge shoulder surface) of the new ridge.

The ridge side forming part 31 has a number of ridge side forming plates 33 that compact the embankment by pushing it in at the rear side in the direction of rotation to form the ridge side. The multiple ridge side forming plates 33 are lined up in the direction of rotation, and a linear step portion 34 is formed between two adjacent ridge side forming plates 33 in the direction of rotation. In addition, a number of spiral step portions 35 are formed on the outer periphery of the ridge top surface forming part 32. The action of these step portions 34, 35 strongly compacts the embankment, forming a strong new ridge that is not likely to collapse. The ridge side forming part 31 has a cylindrical attachment portion (not shown) on the rotation center side, and this attachment portion is directly and detachably attached to the outer periphery of the rotating shaft 3.

As is clear from FIGS. 2 and 3, the attachment 1 is formed, for example, in approximately the same shape and size as the ridge forming body 10, and is used in place of the ridge forming body 10 by a ridge coating machine. It is used by being removably attached to the rotating shaft 3 of No. 2.

Here, the attachment 1 loosely hardens the embankment formed by the embankment body 7 and temporarily rotates in a predetermined direction around the rotation center axis X in the horizontal left and right direction based on the force from the ridge side with respect to the rotation axis 3. A non-driven attachment body 41 that forms a ridge, and a soil adhesion prevention body that is removably attached to the outer surface (ground surface) of the attachment body 41 by means of attachment means 43 and prevents soil from adhering to the outer surface of the attachment body 41. 42.

Note that the temporary ridge formed by the non-driven attachment body 41 is different from the strong new ridge formed by the driven ridge forming body 10, and the soil on the surface thereof is soft and is more prone to collapse than the new ridge. Cheap.

The attachment body (driven rotary body) 41 includes a truncated conical side surface forming part 46 that loosely hardens the embankment formed by the embankment body 7 to form the sloped side surface of the temporary ridge, and a truncated conical side surface forming part 46 on the reduced diameter side of this side surface forming part 46. It has a cylindrical upper surface forming part 47 that is provided at the end and loosely hardens the embankment formed by the embankment body 7 to form a horizontal upper surface of the temporary ridge.

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

Each of the soil adhesion prevention members (for example, soil adhesion prevention plates that are elastic bodies) 51 and 52 is made of a material to which soil does not easily adhere, such as an elastically deformable material such as a rubber plate, a resin plate, or a metal plate. . Each of the soil adhesion prevention members 51 and 52 has its front end in the rotational direction removably attached to the outer surface of the attachment main body 41 (the outer circumferential surface of the side surface forming section 46 and the outer circumferential surface of the upper surface forming section 47) by an attaching means 43. The soil adhesion prevention members 51 and 52 are arranged so that adjacent ones in the rotational direction partially overlap each other, but there may be no overlapping portion.

In the illustrated example, the entire outer peripheral surface of the side surface forming part 46 and the entire outer peripheral surface of the upper surface forming part 47 are covered with the soil adhesion prevention body 42, but for example, only a part of the outer peripheral surface is covered with an elastic member or the like. The attachment body 41 may have a structure covered with a soil adhesion prevention body, or may have a structure in which, for example, the soil adhesion prevention body 42 is not provided and the outer surface of the attachment body 41 is exposed. Furthermore, 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 attachment prevention member is attached to the attachment body at the front end in the rotation direction and at the middle part in the rotation direction. But that's fine.

The attachment body 41 also has a securing means 55 for ensuring that the ridge coating machine 2 moves in a straight line in the direction of travel based on the travel of the tractor when the attachment 1 is attached to the rotating shaft 3 and the ridge coating machine 2 is used for work (when forming temporary ridges).

The securing means 55 has an inner plate 56, which is an annular, plate-shaped first insertion part located at the inner end (left end), which is one end of the attachment body 41 in the left-right direction, and whose outer peripheral end is inserted so as to penetrate into the rice field surface, and an outer plate 57, which is an annular, plate-shaped second insertion part located at the outer end (right end), which is the other end of the attachment body 41 in the left-right direction, and whose outer peripheral end is inserted so as to penetrate into the top surface of the temporary ridge. In other words, the securing means 55 is made up of the inner plate 56 and the outer plate 57, which are different sizes from each other.

The inner plate 56 is provided at the inner end of the side surface forming part 46, and the outer peripheral end of the inner plate 56 projects radially outward from the inner end of the side surface forming part 46. In other words, the inner plate 56 has an annular insertion plate portion 56a at its outer peripheral end that is inserted into the rice field of the field. This inner plate 56 has a circular opening 58 formed therein.

Note that the insertion plate portion 56a of the inner plate 56 has a plurality of mounting holes 54 arranged at intervals in the circumferential direction. This mounting hole 54 can be used for an enlarged diameter member (not shown) that is inserted deeper into the rice field than the insertion plate portion 56a, an extended soil adhesion prevention member (not shown) that prevents soil from adhering to the insertion plate portion 56a, etc. This is for attaching it to the inner plate 56.

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

A circular opening 59 is formed in this outer plate 57, and this 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 body 41 has a cylindrical attachment portion (boss) 61 provided at the outer end (right end) of the side surface forming portion 46. As shown in FIG. This attachment portion 61 is removably 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. Note that the bearing 63 and the inner boss 64 constitute a blocking means 65 that blocks the transmission of power (rotational force) from the rotating shaft 3 to the attachment body 41.

That is, the attachment main body 41 is rotatably attached to the rotating shaft 3 via a power transmission cutoff means (bearing means) 65. In short, the attachment portion 61 of the attachment body 41 is detachable and rotatable relative to the rotating shaft 3.

And unlike the mounting part (not shown) on the rotation center side of the ridge forming body 10, the mounting part 61 on the rotation center side of the attachment body 41 does not receive power from the rotating shaft 3. Therefore, unlike the ridge forming body 10, the attachment body 41 is not driven to rotate by power from the rotating shaft 3, but is driven to rotate based on the force it receives from the ridge side where it is in contact with the ground.

Further, the mounting means 62 includes, for example, a bolt 66 that can be screwed onto the female threaded portion 3a of the rotating shaft 3, a cylindrical collar 67, and a washer 68 into 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 adjustment member, the position of the attachment body 41 in the left-right direction with respect to the rotating shaft 3 can be changed. In other words, the attachment main body 41 can be adjusted in left and right positions with respect to the rotating shaft 3 of the ridge coating machine 2.

Next, the operation of the above-mentioned attachment 1 will be explained.

First, referring to Figure 5, we will explain the procedure for adjusting the size of a ridge, i.e., for returning a ridge that has become large due to repeated ridge painting work to a desired size (a ridge formation method for returning the ridge to the desired size).

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

Next, using the ridge-making machine 2 with the attachment 1 attached to the rotating shaft 3, the embankment made of the embankment body 7 is loosely compacted with the attachment 1 to form a temporary ridge (step 2).

Thereafter, the attachment 1 is removed from the rotating shaft 3 of the ridge coating machine 2, and then 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 formed by the embankment body 7 is compacted with the ridge forming body 10 to form a new ridge (step 4). As a result, the height and width of the ridges that have become larger due to repeated ridge coating operations are reduced, and new ridges of a desired size are formed.

Here, to explain more specifically based on FIGS. 6 and 7, the operator first moves the ridge forming body from the rotating 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 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 in use) is moved to the original ridge by running the tractor. When the embankment is moved along the moving direction, the embankment is loosely compacted by the attachment 1 and a false ridge is formed.

In other words, when the attachment body 41 is in contact with the ridge via the soil adhesion prevention body 42 and rotates based on the force from the ridge side, the embankment formed by the embankment body 7 is loosely compacted, and the soil on the surface is A soft false ridge is formed.

At this time, since the inner plate 56 of the attachment body 41 is inserted into the rice 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 direction of movement of the entire ridge coating machine) straightness of movement) is ensured. At this time, since the rotating shaft 3 of the ridge coating machine 2 does not need to be driven, for example, if the rotating shaft 3 is configured to have a function of stopping rotation, the rotating shaft 3 may not be driven when forming the temporary ridge. It may be stopped.

In addition, during this temporary ridge formation (temporary ridge formation process), the height of the ridge coating machine 2 is stabilized by the attachment 1 and the gauge wheel 23 that are in contact with the ground, so the relative height of the embankment body 7 with respect to the attachment 1 is adjusted. By doing so, the cutting depth (cultivation depth) for the original furrow can be adjusted. Similarly, by adjusting the relative height of the top surface scraping body 8 with respect to the attachment 1, the top surface scraping depth (cultivation depth) with respect to the original furrow can also be adjusted.

Furthermore, by adjusting one or more soil volume adjustment means, the volume of soil for the temporary ridge that is pushed and loosely compacted by the attachment 1 can be adjusted (see FIG. 1).

Specifically, for example, by changing the degree of opening of the retaining plate 81 located at the rear of the embankment body 7, the amount of soil that escapes from the attachment 1 side to the rice field side can be adjusted. Furthermore, by changing the angle of the soil adjustment plate 83 in the side cover body 82 located on the outside of the embankment body 7, the amount of soil that escapes from the attachment 1 side to the opposite field side (outward side) can be adjusted. Furthermore, by changing the left-right position of the auxiliary cover 84 in the cover body 11 that covers the embankment body 7, the amount of earth heaped on the upper surface of the original ridge can be adjusted. Furthermore, by changing the vertical position of the guard 85 in the cover body 11 that covers the embankment body 7, the amount of soil that escapes from the embankment body 7 side to the rice field side can be adjusted.

After that, as shown in FIG. 7(f), after replacing the attachment 1 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 reduced to the desired height and width is formed.

During this process, the temporary ridge is plowed using the embankment 7 and top surface scraping body 8, but because the soil on the surface of the temporary ridge is soft, the embankment 7 and top surface scraping body 8 penetrate deeper than usual, scraping away more soil. As a result, the new ridge is smaller than the ridge that grew larger as a result of repeated ridge-plastering work.

The work shown in Figure 7(f) (work to form a new ridge) may be performed immediately after the work shown in Figure 7(d) (work to form a temporary ridge), or may be performed after a prescribed period of time has passed. For example, if it is performed after a prescribed period of time has passed, part of the temporary ridge may collapse due to rainwater, etc., and soil may be supplied to the rice field surface. Also, when forming a new ridge, the amount of soil for the new ridge can be adjusted, just as when forming a temporary ridge.

According to the attachment 1, a worker such as a farmer can use the attachment main body 41, which is a non-driving type that forms a temporary ridge while being driven to rotate around the rotating shaft 3 based on the force from the ridge side. By using attachment 1, which is relatively inexpensive, large ridges can be adjusted to the desired size, so there is no need to purchase a relatively expensive ridge cutting machine, which reduces the economic burden on the operator. It is possible to reduce the burden on

In addition, since it is equipped with a soil adhesion prevention body 42 that prevents soil from adhering to the attachment body 41, it is possible to properly prevent soil from adhering to the attachment body 41 during work, thereby eliminating the need for soil removal, etc. It is possible to reduce the burden on workers.

Furthermore, since the attachment body 41 has a truncated conical side surface forming part 46 that forms the side surface of the temporary ridge and a cylindrical top surface forming part 47 that forms the top surface of the temporary ridge, it has a shape close to that of a normal ridge. A temporary ridge will be formed, and therefore, the working position will be stable during the work of forming a new ridge, and the desired ridge removal amount can be easily set and the work can be done easily, and from this point of view as well, it is possible to reduce the burden on the worker. Can be done.

Note that the attachment 1 may be one shown in FIG. 8, such as a tire or a gauge wheel. In the attachment 1 shown in FIG. 8, the attachment main body 41 has a cylindrical side surface forming part 46 that loosely hardens the embankment formed by the embankment body 7 to form one vertical side surface of the false ridge.

The side surface forming portion 46 has a cylindrical tubular portion 46a and a disk-shaped plate portion 46b provided at the right end of the cylindrical portion 46a. A first soil adhesion prevention member 71 made of rubber, resin, or the like is provided on the outer peripheral surface of the cylindrical portion 46a so as to cover the entire outer peripheral surface. Although not shown, the first soil adhesion prevention member 71 may have multiple protrusions like studded tires, for example.

Similarly, a second soil adhesion prevention member 72 made of rubber, resin, etc. is provided on the outer peripheral surface of the upper surface forming portion 47 so as to cover the entire outer peripheral surface. The member 72 may have a plurality of protrusions. Note that the first soil adhesion prevention member 71 and the second soil adhesion prevention member 72 constitute the soil adhesion prevention body 42.

The attachment 1 shown in FIG. 8 can also provide the same effects as the attachment 1 described above. Note that, for example, a soil adhesion prevention member may be provided on the outer surface of the plate-like portion 46b of the side surface forming portion 46. Further, for example, a structure may be adopted in which the outer surface of the attachment main body 41 is exposed without providing the soil adhesion prevention members 71 and 72.

Further, the attachment 1 may be of the type shown in FIG. 9 in which the side surface of the temporary ridge is formed in a plurality of steps, for example. In the attachment 1 shown in FIG. 9, the attachment main body 41 has a side surface forming part 46 that loosely hardens the embankment formed by the embankment body 7 to form the side surface of the false ridge into a plurality of steps.

This side surface forming portion 46 includes a cylindrical first cylindrical portion 46a, a disk-shaped first plate portion 46b provided at the right end of this first cylindrical portion 46a, and a first plate-like portion 46b. It has a cylindrical second cylindrical part 46c provided at the inner circumferential end of 46b, and a disc-shaped second plate part 46d provided at the right end of this second cylindrical part 46c. There is.

The attachment 1 shown in FIG. 9 can also provide the same effects as the attachment 1 described above. Although the attachment 1 illustrated in FIG. 9 is not equipped with the soil adhesion prevention body 42, soil adhesion may occur, for example, on the outer peripheral surfaces of the cylindrical portions 46a and 46c of the side surface forming portion 46 and the outer surfaces of the plate-like portions 46b and 46d. A prevention member may be provided, or a soil adhesion prevention member may be provided on the outer peripheral surface of the upper surface forming portion 47. Further, the number of stages of the side surface forming portions 46 may be three, or may be four or more.

Further, in any of the embodiments, it is preferable that the attachment main body has a securing means for ensuring straightness, but it may be configured without the securing means. Further, for example, a soil adhesion prevention member may be provided on the members (inner plate 56, outer plate 57) constituting the securing means.

Further, 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 of the attachment body that contacts the ridge (the ground surface) may be made of a material to which soil does not easily adhere. .

Further, the attachment that can be replaced (replaced) with the ridge forming body may be configured to consist only of an attachment body that forms the temporary ridge while rotating based on the force from the ridge side with respect to the rotating part of the ridge coating machine.

Furthermore, to facilitate the attachment of the attachment body to the rotating part of the ridge coating machine, a restricting means (e.g., a removable pin, etc.) may be provided to restrict the rotation of the inner boss 64 relative to the mounting part (boss) 61 during the attachment work.

Although several embodiments and variations of the present invention have been described, it is possible to combine the various embodiments and variations as appropriate without departing from the spirit of the present invention.
