<First Embodiment>
[Configuration of ridge coater 100]
Hereinafter, the configuration of the ridge coating machine 100 according to the first embodiment will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a perspective view showing the configuration of the ridge coating machine 100 of the first embodiment. FIG. 2 is a plan view showing the configuration of the ridge coating machine 100 of the first embodiment. FIG. 3 is a side view showing the configuration of the ridge coating machine 100 of the first embodiment.

As shown in FIGS. 1 to 3, the ridge coating machine 100 is roughly classified into a mounting portion 110 mounted on a link mechanism (for example, a three-point link mechanism) of a traveling machine body (not shown) such as a tractor, and a ridge alignment. An arranging body 120 for performing ridge work, a pre-processing unit 130 for arranging the soil to be supplied to the arranging body 120, an heaven field processing unit 140 for processing the heavens of the ridge, a mounting unit 110 and an arranging body 120. A connecting portion 150 for connecting the above is provided as a basic configuration. The trimming body 120, the preprocessing unit 130, and the heavens processing unit 140 may be collectively referred to as a working unit.

The mounting portion 110 includes lower link connecting portions 111a and 111b and a top link connecting portion 112, and also includes a support member 113 to which the connecting portion 150 is mounted. Further, the mounting unit 110 includes an input shaft 114 connected to the PTO shaft of the traveling machine body via a transmission joint such as a universal joint, and the power transmitted to the input shaft 114 is transmitted to the transmission mechanism of the coupling unit 150. The support member 113 also has a mechanism for transmitting to the.

One end of the connecting portion 150 is supported by the support member 113 of the mounting portion 110, the other end is attached to the working portion, and includes a link member 131 and an offset frame 132. The link member 131 is a member whose one end is rotatably supported on the mounting portion 110 side and whose other end is rotatably supported by the rear frame 170, and which controls the working position of the trimming body 120. .. The offset frame 132 includes a power transmission unit that transmits power to the ridge body 120, one end of which is rotatably attached to the support member 113, and the other end of which is rotatably supported by a working unit. ..

The offset frame 132 and the link member 131 are arranged in parallel, and these and the support member 113 form a parallel link mechanism. Therefore, the working direction of the ridge body 120 does not change with respect to the swing of the connecting portion 150. That is, the offset movement of the ridge body 120 is possible while maintaining the ridged work surface.

In this embodiment, a parallel link mechanism is adopted to facilitate the control of the offset control cylinder 133 and the working direction control cylinder 134. However, as an embodiment of the present invention, the offset control cylinder 133 and The working direction control cylinder 134 may be configured to be controlled independently, and the same control as that described below is possible even in the case of an embodiment in which such a parallel link mechanism is not formed.

The rectifying body 120 is attached through a mounting base 10 to the top of the substantially frusto-conical sloped ridge portion 121 that is rotatably supported about a rotation axis, and is attached to the top of the sloped ridged portion 121 via the mounting base 10. And an upper surface ridge portion 122 extending to the. The rectifying body 120 is configured such that rotational power is transmitted via the power transmission mechanism in the transmission support case 135. The specific configuration of the slope adjusting section 121 will be described later.

The pre-processing unit 130 cuts off a part of the old ridge and performs earthing work. The above-mentioned slope surface ridge portion 121 applies new soil to the slope surface of the old ridge that has been cut by the soil piled up forward by the pretreatment unit 130. For example, as the pretreatment unit 130, a rotary tillage type pretreatment mechanism in which a plurality of tillage claws are mounted on a drive shaft can be adopted.

The sky field processing unit 140 performs a work of scraping off the sky field (upper surface) of an old ridge. After the upper surface ridge portion 122 has scraped off the upper surface of the old ridge by the heaven-field processing unit 140, the upper surface ridge portion 122 flattens the upper surface to form a new heaven. For example, as the heaven-field processing unit 140, similarly to the pre-processing unit 130, a rotary tilling type pre-processing mechanism in which a plurality of tilling claws are mounted on a drive shaft can be adopted.

Further, in the vicinity of the ridge body 120, a position sensor 160 as a work position detecting means for detecting the work position of the ridge body 120 is equipped. The position sensor 160 is arranged behind the ridge body 120 via a mounting case 161 from a support case (not shown). The position sensor 160 has a built-in potentiometer for detecting the rotational displacement of the rotary shaft, and one end of the sensor rod 162 is fixed to the rotary shaft. The position of the sensor rod 162 can detect the distance between the slope adjusting portion 121 and the slope of the ridge.

Although not shown, an angle sensor may be arranged as a work direction detecting means for detecting the work direction of the trimming body 120. In this case, it is preferable that the angle sensor does not detect a change in the relative direction of the ridge body 120 with respect to the connecting portion 150, but a change in the working direction of the ridge body 120 alone in a field scene. .. For example, as the angle sensor, a gyro sensor may be arranged around the transmission shaft in the offset frame 132.

[Structure of slope adjusting section 121]
FIG. 4 is a plan view of the slope adjusting portion 121 in the first embodiment, and FIG. 5 is a side view of the slope adjusting portion 121 in the first embodiment. It is the figure which each looked at the sloped ridge part 121 of a substantially truncated cone shape from the top part side and the side. As described with reference to FIGS. 1 to 3, the slope adjusting portion 121 of the present embodiment is actually installed with the top side facing the ridge, and rotates in the direction of the arrow around the rotation axis. Perform ridge coating work. In addition, in the present embodiment, the traveling direction of the traveling machine body is the right direction toward FIG. 4.

As shown in FIG. 4, the slope adjusting portion 121 is configured by connecting a plurality of adjusting plates with the combination of the first adjusting plate 21 and the second adjusting plate 22 as a unit. Here, eight 1st ridge boards 21 and 8 2nd ridge boards 22 are connected by turns, and are comprised by a total of 16 ridge boards. In other words, the slope adjusting section 121 includes eight adjusting units 20 in which the combination of the first adjusting plate 21 and the second adjusting plate 22 is a unit. However, the numbering plate and the number of units are not limited to the numbering plate which constitutes the sloped number adjusting part of the present invention.

In addition, in the sloped ridge portion 121 of the present embodiment, the base ends of the plurality of ridge plates are attached to the attachment base 10. Since each of the plurality of ridge plates that configure the sloped surface ridge portion 121 of the present embodiment are directly welded to each other, the ridge plates can function as the ridge body even without the attachment base 10. In the case of the present embodiment, the mounting is performed for the purpose of increasing the strength of the sloped surface ridge portion 121 and for connecting the upper surface ridged portion 122 and the sloped surface ridged portion 121 shown in FIGS. 1 to 3 to each other. A base 10 is provided.

Note that, as described above, in the present embodiment, each of the plurality of ridge plates is directly welded by welding, but the present invention is not limited to this, and it may be indirectly connected via a connecting member. Good. In this case, each ridge plate and the connecting member may be welded. Also, although welding has been described as an example of the joining means, the present invention is not limited to this, and it is also possible to connect the respective ridge plates by joining using other fixing members such as bolts and nuts. Is.

Further, as shown in FIG. 4, the slope adjusting portion 121 of the present embodiment is designed such that the outermost edge (outermost edge) of the slope adjusting portion 121 is circular in plan view. .. However, this is only an example, and in the side view shown in FIG. 5, the lowermost end (the lowermost edge, that is, the rightmost edge in FIG. 5) of the sloped ridge 121 is the sloped ridge 121. It may be designed to be substantially perpendicular to the rotation axis (not shown). In this case, the outermost edge of the slope adjusting portion 121 in plan view is not circular, but the bottom end of the slope adjusting portion 121 is brought into contact with the ground or the like in the state shown in FIG. It becomes possible to mount it stably. In addition, at that time, in order to protect the edge of the sloped surface rectifying portion 121 that comes into contact with the ground contact, as shown in FIGS. 6(A) and 6(B), in the plan view shown in FIG. 6(A). It is also possible to cover the outermost edge of the slope adjusting portion 121 (the lowermost end of the slope adjusting portion 121 in the side view shown in FIG. 6B) with the ring-shaped member 60.

Here, FIG. 7(A) is a diagram showing the first trimming plate 21 in the first embodiment, and FIG. 7(B) is a diagram showing the second trimming plate 22 in the first embodiment. .. In addition, FIG. 8 is a diagram showing a trimming unit 20 in which a first trimming plate 21 and a second trimming plate 22 according to the embodiment of the present invention are combined.

As shown in FIG. 7(A), the first ridge plate 21 is connected to the working surface 21a that functions as a portion for actually contacting the ridges and solidifying the soil during operation, and the adjacent second ridge plate 22. And a joint surface 21b for At this time, the joint surface 21b is bent toward the back side of the paper so as to form an obtuse angle with the working surface 21a.

Further, as shown in FIG. 7B, the second ridge adjusting plate 22 also has an action surface 22a and a joint surface 22b. At this time, the joint surface 22b is also bent toward the back side of the paper so as to form an obtuse angle with the acting surface 22a. In the present embodiment, the angle formed by the working surface 21a of the first ridge plate 21 and the joint surface 21b is larger than the angle formed by the working surface 22a of the second ridge plate 22 and the joint surface 22b.

By combining these, as shown in FIG. 8, the bonding surface 21b of the first ridge plate 21 is bonded to the surface on the back side of the working surface 22a of the second ridge plate 22. As described above, in the present embodiment, welding is performed in a state in which the joint surface 21b of the first ridge plate 21 is aligned with the back surface of the working surface 22a of the second ridge plate 22, and the two are connected together. .. Then, with the arranging unit 20 combined in this way as a unit, a slope-shaped ridge portion 121 having a substantially truncated cone shape is formed by connecting a plurality of arranging plates.

Note that, unlike the above, when forming the slope adjusting portion 121, it is also possible to alternately weld the first prepared adjusting plate 21 and the second adjusting plate 22 prepared in advance in order. In this embodiment, first, a plurality of ridge adjusting units 20 formed by welding the first ridge adjusting plate 21 and the second ridge adjusting plate 22 are formed, and the plurality of ridge adjusting units 20 are welded to each other to form the slope adjustment. The part 121 is formed. When connected in such an order, an error is not accumulated in the angle formed by the first ridge plate 21 and the second ridge plate 22 when welding the ridge plates, and the sloped ridge portion 121 as a whole is It is possible to improve the alignment accuracy of.

Next, the roles of the first ridge plate 21 and the second ridge plate 22 in the slope ridge portion 121 in the present embodiment will be described. 9 to 11 are schematic diagrams showing a cross section of the slope adjusting portion 121 in the first embodiment taken along an arbitrary horizontal plane (a plane perpendicular to the rotation axis).

In FIG. 8, the first ridge adjusting plate 21 and the second ridge adjusting plate 22 are joined to each other through their respective joint surfaces 21b and 22b, so that they are connected in a generally circular shape. Here, the arc 30 indicated by the alternate long and short dash line connects the point farthest from the rotation axis (not shown) in the first ridge plate 21 (the end point 34 of the action surface 21a in the first ridge plate 21 described later). It is an arc and corresponds to a part of the maximum rotation locus (outermost circle) of the sloped surface rectifying portion 121 in the cross section shown in FIG. 9.

Further, in FIG. 9, the working surface 22a of the second ridge plate 22 is defined as a range from the starting point 31 to the end point 32, and the working surface 21a of the first ridge plate 21 is defined from the starting point 33 to the end point. It is defined as a range up to 34. Although the terms “start point” and “end point” are used here, they actually mean one point of a line segment extending in the depth direction.

At this time, as shown in FIG. 9, as viewed from the upstream side in the rotation direction, from the start point 31 to the end point 32 of the working surface 22a of the second ridge plate 22, and the working surface of the first ridge plate 21. From the start point 33 to the end point 34 of 21a, the distance between the working surface and the ridge is gradually reduced (conversely, the distance from the rotating shaft to the working surface is gradually increased). There is. Actually, a step is formed when the second ridge plate 22 moves to the first ridge plate 21, but the entire ridge unit 20 moves from the upstream side to the downstream side in the rotation direction as a whole. , The distance between the working surface and the ridge gradually becomes smaller.

As described above, in the cross section shown in FIG. 9, the distance from the end point 34 on the working surface 21a of the first ridge plate 21 to the rotation axis is the longest, and the start point 31 on the working surface 22a of the second ridge plate 22 is 31. To the axis of rotation is shorter than the distance from the end point 34 on the working surface 21a of the first ridge plate 21 to the axis of rotation. As a result, during ridge coating work using the sloped ridge portion 121, the working surface 22a of the second ridge plate 22 and the working surface 21a of the first ridge plate 21 gradually move from the upstream side to the downstream side. The ridge comes into contact with the ridge while increasing the contact pressure, and the ridge can be firmly applied and solidified.

Here, FIG. 10 and FIG. 11 show three parameters when paying attention to each of the first ridge plate 21 and the second ridge plate 22 constituting the slope ridge portion 121 of the present embodiment. There is. Specifically, the parameter (X) indicates the width ((X1), (X2)) of the working surface of each ridge plate. The parameter (α) indicates the angle ((α1), (α2)) formed by the working surface of each ridge plate and the slope of the ridge. The parameter (R) is the radius ((R1), (R2)) of the maximum rotation locus formed by each ridge plate, that is, the distance between the end point on the working surface of each ridge plate and the rotation axis. There is.

As shown in FIGS. 10 and 11, in the slope regulating portion 121 of the present embodiment, the width (X2) of the working surface 22a of the second regulating plate 22 is the same as that of the working surface 21a of the first regulating plate 21. It is wider than the width (X1). Specifically, the second ridge plate 22 is a portion that is desired to perform a work of pressurizing the ridges more strongly, and therefore is designed to be wide in order to secure a large work range.

Further, in the present embodiment, as will be described later, the relationship of α1<α2 is provided between the angles α1 and α2 shown in FIGS. 10 and 11. Therefore, in the present embodiment, while maintaining the relationship of α1<α2, the width X1 of the working surface 21a and the width X2 of the working surface 22a are adjusted to balance the shape of the entire sloped surface recess 121. .. However, this is an example, and the width X1 and the width X2 may be designed to have the same width.

In addition, the slope adjusting portion 121 of the present embodiment is a line segment orthogonal to the line segment 41 connecting the rotation axis and the farthest point (the end point 34 in FIG. 9) of the first adjustment plate 21 from the rotation axis. The angle (α1) formed by 42 with the working surface 21a of the first ridge plate 21 (see FIG. 10) is the farthest point from the rotation axis of the second ridge plate 22 (the end point 32 in FIG. 9). A line segment 44 that is orthogonal to the line segment 43 that connects and is smaller than the angle (α2) (see FIG. 11) that is formed with the working surface 22a of the second rib plate 22.

At this time, the line segment 42 in FIG. 10 corresponds to the tangent line at the end point 34 with respect to the maximum rotation locus 30a formed by the first ridge adjusting plate 21. That is, the above-mentioned angle α1 can be said to be an angle formed by this tangent line and the working surface 21a of the first rib plate 21. Further, since the line segment 42 corresponds to the slope of the ridge during the ridge coating work, the angle α1 described above can be said to be an angle formed by the slope of the ridge and the working surface 21a of the first ridge plate 21.

Similarly, the line segment 44 in FIG. 11 corresponds to the tangent line at the end point 32 with respect to the maximum rotation locus 30b formed by the second ridge plate 22. That is, the above-mentioned angle α2 can be said to be an angle formed by this tangent line and the working surface 22a of the second ridge plate 22, or can be said to be an angle formed between the slope of the ridge and the working surface 22a of the second ridge plate 22. ..

In the above-mentioned prior art, although it is possible to form ridges that are hard to collapse by gradually strengthening the contact of the ridge board with respect to the ridges, there is a problem that something like a scratch mark is left on the ridge surface by the end of the ridge board. It was On the other hand, the slope adjusting portion 121 of the present embodiment uses two kinds of adjusting plates, that is, a first adjusting plate 21 and a second adjusting plate 22, and the angle α1 is smaller than the angle α2. It is designed to be designed. As a result, the first ridge plate 21 can be gently hit against the slope of the ridge, and it is possible to form a strong ridge and prevent scratches and the like from remaining on the ridge surface.

As described above, in the cross section shown in FIG. 9, from the start point 31 on the working surface 22a of the second ridge plate 22 to the end point 34 on the working surface 21a of the first ridge plate 21, each working surface The distance between the rotation axis and the rotation axis gradually increases. Therefore, the radius (R1) of the maximum rotation locus 30a formed by the first ridge plate 21 shown in FIG. 10 is larger than the radius (R2) of the maximum rotation locus 30b formed by the second ridge plate 22 shown in FIG. large.

In order to verify the operation and effect of the example (hereinafter, referred to as “first example”) of the rectifying body 120 including the sloped surface rectifying portion 121 in the first embodiment, the same shape 8 as the first example is used. The following performance comparison test was carried out using a general shaped body (hereinafter, referred to as “comparative example”) composed of a single substantially fan-shaped shaped board.

In the performance comparison test, the finished performance of the ridges after the ridge coating work was performed using the ridged bodies of the first example and the comparative example were compared. The evaluation of the performance is performed by sensory evaluation by a plurality of persons skilled in the art (5 points: best to 1 point: evaluation in 5 stages of the worst), and an average score of sensory evaluation by each evaluator is calculated for each of a plurality of evaluation items The evaluation was performed by a method of evaluating the performance of the ridge body by the total score of the average points. There are three types of evaluation items: “Amount of clods generated”, “Size of clods”, and “Finishing performance”. Regarding “Finishing performance”, each part of the ridge is further subdivided into “Shoulder” and “Upper slope”. , "Central slope" and "lower slope" were evaluated for each core item.

Further, in the performance comparison test, in order to equalize the test conditions such as soil quality, water content, tillage depth, and height of the original ridge in the field, the ridge coating work using each of the ridges was performed in one ridge. It went for about 3 m. Moreover, the rotation speed of the ridge body was set to a relatively high rotation speed and a relatively low rotation speed, and the ridge coating work at each rotation speed was compared.

The specific test conditions are shown below.
・Tractor and work machine: SL60PC (tractor) and XRM (ridge coating work machine)
・Head height of the field: 30 cm
・Soil texture: Clay (fine grain strong clay)
・Amount of water in field: small amount to appropriate amount ・Rotation speed of ridges: 74 rpm and 60 rpm

The following table shows the results of the performance comparison test using the trimmed bodies of the first example and the comparative example.

According to the results of the performance comparison test shown in Table 1, the total score of the first example is higher than that of the comparative example at any rotation speed, so that the ridge after the ridge coating work is performed more than the comparative example. It can be seen that the finished performance is good. As a factor causing such a result, since the number of ridge boards in the first example is larger than that in the comparative example, the ridges can be finely pushed by a large number of ridge boards, and the ridges can be adjusted against the slope. It is considered that since the ridge board hits gently, it was prevented that the surface of the ridge was scraped or a lump of soil was generated, and the ridge was finished well.

Further, since all the ridge boards of the comparative example have the same shape, the ridges are monotonically pushed in at the same repetition period of strength and weakness, whereas in the first embodiment, the first ridge board 21 and the second ridge board. 22 uses two different shaped ridge boards and is designed to make the angle α1 smaller than the angle α2, so that the ridge pushing force is changed irregularly. Therefore, it is considered that a strong ridge having a better finish than the comparative example was formed.

<Second Embodiment>
In the present embodiment, a configuration of a slope adjusting portion using an adjusting plate having a shape different from that of the first embodiment will be described. Specifically, in the sloped ridge portion 121a of the present embodiment, a part of the first ridge plate 51 is curved to form a recess.

FIG. 12 is a schematic view showing a cross section of the sloped surface ridge portion 121a in the second embodiment taken along an arbitrary horizontal plane (a plane perpendicular to the rotation axis). FIG. 13 is a perspective view of a part of the sloped surface rectifying portion 121a according to the second embodiment as seen obliquely from above. It should be noted that a detailed description will be given here focusing on the parts different from the first embodiment, and the same parts as the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

In FIG. 12, a part of the first ridge plate 51 is curved toward the rotation axis, and the end portion 22c of the second ridge plate 22 is projected to the curved portion 51a. In this case, the curved portion 51a of the first ridge adjusting plate 51 forms a concave portion when viewed from the ridge side, and therefore does not act in the ridge coating work. Therefore, the width of the acting surface is relatively narrower than that of the first ridge plate 21 in the first embodiment.

However, by providing the curved portion 51a, the degree of freedom in design regarding the inclination adjustment of the working surface of the first ridge adjusting plate 51 is improved, and the effect that the angle α1 described using FIG. 10 can be made smaller can be obtained. To be Further, since there is room for the end portion 22c of the second ridge plate 22 to slightly bend toward the curved portion 51a, the force for pushing the ridges is dispersed, and scratches on the ridge surface can be further prevented. ..

Further, by providing the curved portion 51a, the strength of the first ridge adjusting plate 51 can be improved.

<Third Embodiment>
In the present embodiment, a configuration of a slope adjusting portion using an adjusting plate having a shape different from those of the first and second embodiments will be described. Specifically, in the sloped ridge portion 121b of the present embodiment, a part of the first ridge plate 51 and the second ridge plate 52 is curved to form a recess.

FIG. 14: is a schematic diagram showing the cross section which cut|disconnects the sloped surface ridge part 121b in 3rd Embodiment by the arbitrary horizontal surface (plane perpendicular to a rotating shaft). It should be noted that here, detailed description will be given focusing on parts different from the first embodiment, and the same parts as the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

In FIG. 14, part of the first ridge adjusting plate 51 is curved toward the rotation axis, and the end portion 52b of the second ridge adjusting plate 52 is projected to the curved portion 51a. Similarly, a part of the second ridge adjusting plate 52 is also curved toward the rotation axis, and the end portion 51b of the first ridge adjusting plate 51 is projected to the curved portion 52a. In this case, since the curved portion 51a and the curved portion 52a form a concave portion when viewed from the ridge side, they do not act in the ridge coating work. Therefore, the widths of the working surfaces of the first ridge plate 51 and the second ridge plate 52 in the present embodiment are relatively larger than those of the first ridge plate 21 and the second ridge plate 22 in the first embodiment, respectively. Becomes narrower.

However, as described in the second embodiment, by providing the curved portion 51a and the curved portion 52a, the degree of freedom in design is improved with respect to the inclination adjustment of the working surfaces of the first ridge plate 51 and the second ridge plate 52. The effect is obtained. Further, since the end portion 51b of the first ridge plate 51 is bent toward the curved portion 52a and the end portion 52b of the second ridge plate 52 is bent toward the curved portion 51a, the ridges are formed in each ridge plate. The pushing force is dispersed, and scratches can be more prevented from remaining on the ridge surface.

Further, as described in the second embodiment, by providing the curved portion 51a and the curved portion 52a, it is possible to improve the strength of the first ridge plate 51 and the second ridge plate 52. Further, by providing the curved portion 51a and the curved portion 52a, the manufacturing strain that may occur when assembling the slope adjusting portion 121b by welding the respective adjusting plates is further reduced, so that the slope adjusting portion 121b. It is possible to further improve the alignment accuracy as a whole.

Although the present invention has been described above with reference to the drawings, the present invention is not limited to the above-described embodiments and can be appropriately modified without departing from the spirit of the present invention.
