Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ridge shaping device, and more particularly to a ridge shaping device that is mounted on an earthmoving vehicle and is effectively used as a working device for shaping ridges.

As is well known to those skilled in the art, in field maintenance work, ridges that are approximately semicircular or semielliptical in cross section and that extend substantially straight are filled and compacted using an appropriate earthmoving vehicle such as a bulldozer. 'Round shaping is performed to shape the earth and sand (underlying base) into a ridge with a substantially trapezoidal cross section. In such ridge shaping, an earthmoving vehicle equipped with a ridge shaping blade with a flat front surface as a working device at the front end is generally used to carry out the following ridge shaping method.

That is, the earth-moving vehicle is positioned perpendicular to the longitudinal direction of the ridge-filling soil, and then the ridge-shaping blade of the ridge-filling soil is moved forward by the earth-moving vehicle and operated by the ridge-shaping blade. The opposing portions are locally cut, thus shaping the substantially horizontal ridge top surface and one of the ridge slopes having an approximately 45 degree inclination, and then cutting the ridge soil. Then, the earthmoving vehicle is positioned at an unshaped part adjacent to the part where the upper surface of the ridge and one of the slopes of the ridge have been shaped, and the same shaping operation is repeated.

However, as is easily understood, the above-mentioned ridge shaping method requires (a) considerable skill in operating the ridge shaping blade, and also requires a considerable degree of skill in operating the ridge shaping blade; Since cutting and shaping must be performed locally and intermittently, work efficiency decreases.

(b) Since it has to be carried out locally and intermittently, steps are likely to occur on the shaping surface (the upper surface of the ridge and the sloped surface of the ridge);
There are disadvantages such as poor shaping accuracy (linear precision and height precision of the shaped ridge).

The present invention was made in view of the above facts, and its first object is to provide an excellent ridge that can be installed on an earthmoving vehicle and that enables ridge shaping to be carried out easily and with high efficiency. The purpose of the present invention is to provide a plastic surgery device.

A second object of the present invention is to provide an excellent ridge shaping device that can be mounted on an earthmoving vehicle to easily perform ridge shaping and to shape ridges with high precision. .

According to the present invention, in accordance with the first object, the ridge shaping device is equipped on an earthmoving vehicle, and includes a support frame mounted on one side of the earthwork vehicle, and a support frame mounted on one side of the earthwork vehicle. a first inclined surface shaping blade having a cutting edge extending upward and laterally outward at a predetermined angle, the first inclined surface shaping blade being attached to the first inclined surface shaping blade; an upper shaping blade having a cutting edge extending laterally in a substantially horizontal direction; and a second blade attached to the upper shaping blade having a cutting edge extending downwardly and laterally outwardly at a predetermined angle. Provided is a ridge shaping device characterized by comprising two blades for shaping an inclined surface.

Further, according to the present invention, in response to the above second objective,

The connecting bosses connected to each other are connected by the connecting pin 50, and thus the fourth support member 24 connects the connecting pin 50 to the third support member 22 (the central axis of the connecting pin 50 constitutes a vertical axis extending in the vertical direction). It is mounted so that it can pivot freely.

Furthermore, in the illustrated example, as shown in FIGS. 4 and 5, a guide protrusion 52 is provided on the back surface of the lower end of the connection bracket 40 fixed to the first support member 18. The guide protrusion 52 is formed of side plates 54 fixed to the back surface of the connection bracket 40 at intervals, and end plates 56 fixed between the side plates 54. On the other hand, a support body 58 is attached to one of the pair of bush arms 4 of the bulldozer 8. The support body 58 has an upper body 60 and a lower body 62, and the upper body 60 and the lower body 62 are connected by a plurality of bolts and nuts, so that the bush arm 4
It is removably attached to the. A pair of protruding bracket parts 6 are provided on both sides of the upper surface of the upper body 60 at intervals in the lateral direction.

A guide member 70 is attached to the upper surface of the support body 58. To explain in more detail, the guide member 70 is a pair of protruding brackets whose one end is fixed to the support body 58! B64Vc position Rf"+ end face plate 7 connected to the protruding bracket part 64 by a connecting pin 72 and fixed to one end thereof
4 is attached to the support body 58' by being inserted into a recess 75 defined by the upper surface of the upper body 60 and the locking part 66. Therefore, the guide member 7
0 is prevented from moving in the lateral direction by a pair of protruding bracket parts 64, is prevented from moving in the front and back direction by the connecting bin 72, and is further centered around the connecting bin 72 by the upper surface of the upper main body 60 and the locking part 66. Pivoting movement is prevented and is thus firmly connected to the upper surface of the support 58. The guide member 70 includes a base plate 76, a pair of side plates 78 extending rearward from both ends of the base plate 76, and a pair of side plates 78 extending in both lateral directions from the rear ends of each of the pair of side plates 78.

The base side (head side) of the connecting pin 10 is connected to a connecting bracket 98 fixed to the upper surface of the intermediate portion of the first support member 18.
It is rotatably mounted by 0. Therefore, when the first hydraulic cylinder mechanism 82 is expanded (or contracted), the first support member 18 moves its guide protrusion 52 along the guide groove 68 of the guide member 700, thereby causing the first support member 18 to move.
Arrow 35 (or arrow 37) centered on the horizontal axis 26
When the VC is reliably rotated in the upward (or downward) direction shown by and the second fluid pressure cylinder mechanism 84 is expanded (or contracted), the second support F? (; The control 20 and the third support member 22 are respectively aligned with the arrows 39 about the above-mentioned vertical axes.
and 43 (or arrows 41 and 45), the fourth support member 24 is moved laterally inward (or laterally outward).

Furthermore, the first inclined four-sided shaping plate 12 is attached to the support frame 1o. Referring again to FIGS. 1 to 3, the fourth support groove 8 material 2 of the support frame 10

As shown in FIGS. 1 and 6, the first slope shaping blade 12 includes a front board 106 having a substantially arc-shaped cross section, and a cutting edge 108 attached to the lower edge of the front board 106. Contains.

The cutting edge 108 of the first slope shaping blade 12 extends upwardly and laterally outward at a predetermined angle, typically a 45 degree angle, with respect to the horizontal, as shown in FIG. It extends at an angle. A pressing shoe 110 is attached to the back surface of the first slope shaping blade 12, as shown in FIGS. 2, 3, and 6. With reference to FIGS. 2 and 6, this pressing shoe 110
To explain, the pressing shoe 110 includes an elongated curved plate 112 having a substantially arcuate cross section;
A pair of lip plates 114 are fixed to the upper surface of the curved plate 112 at three positions spaced apart from each other in the longitudinal direction, with a slight space between them in the longitudinal direction. On the other hand, on the back side of the first slope shaping blade 12, there are connecting plates 1 at each of three positions spaced apart in the longitudinal direction.
16 (only one is shown in FIGS. 1 and 6) is fixed. Each of the connecting plates 116 has a front end portion of a pair of groove plates 114 connected to the connecting bin 11.
8, which are rotatably connected. Therefore, due to its own weight, the pressing shoe 110 is biased counterclockwise in FIG.
The front ends of the blades are respectively positioned at positions where they abut against the back surface of the first slope shaping blade 12.

The above-mentioned upper surface shaping blade 14 is attached to the first inclined surface shaping blade 12 provided with the upper pressing shoe 110 . The upper surface shaping blade 14 preferably follows the cutting edge 108 of the first inclined surface shaping blade 12.
It is mounted so that its position can be adjusted freely along the (this mounting style will be described later). The upper surface shaping blade 14 is also shown in FIG.

As shown in FIGS. 2, 6, and 7, it includes a front board 120 having a substantially arcuate cross section and a cutting edge 122 attached to the lower edge of the front board 120. The cutting edge 122 of the top shaping blade 14 extends laterally substantially horizontally, as shown in FIG.

To explain how the upper surface shaping blade 14 is attached to the first inclined surface shaping blade 12, in the illustrated example, as shown in FIGS. 1, 2, and 6, the first inclined surface shaping blade 14 is A guide shaft 124 extending substantially parallel to the cutting edge 108 is rotatably attached to the upper edge of the surface shaping blade via a support member 126 .

This guide shaft 124 has a male threaded portion formed over substantially its entire length. On the other hand, a guided connecting member 128 in which a female thread is formed is fixed to the upper end portion of the upper surface shaping blade 14 on the inner side in the lateral direction. In addition, the upper surface shaping blade 14
A pair of guided bodies 130 (only one is shown in FIG. 6) are fixed to the back surface of the blade 130 at intervals in the longitudinal direction of the cutting edge 108 of the first slope shaping blade 12. A guide groove 132 is formed in each of the pair of guided bodies 130. The female threaded portion formed on the guided connecting member 128 of the upper surface shaping blade 14 is fitted into the male threaded portion formed on the guide shaft 124, and the pair of guided bodies 130 of the upper surface shaping blade 14 are formed. The guide groove 132 is slidably fitted onto the cutting edge 108 of the first slope shaping blade 12.

Further, a lever 134 for rotating the guide shaft 124 is fixed to one end of the guide shaft 124.

Since this is the through hole, when the lever 134 is manually rotated, the upper surface shaping blade 14 is slid along the cutting edge 108 of the first inclined surface shaping blade 12, and thus the upper surface shaping blade 14 is slid along the cutting edge 108 of the first inclined surface shaping blade 12. (Thus, by doing this, the height of the shaped ridge can be set to a desired value).

A pressing shoe 136 is also attached to the back surface of the above-mentioned upper surface shaping blade 14, as shown in FIGS. 2 and 7. The pressing shoe 136 includes an elongated curved plate 138 having a substantially arcuate cross section. The manner in which the pressing shoe 136 is attached to the upper surface shaping blade 14 is as follows:
2 at intervals in the longitudinal direction on the upper surface of the curved plate 138.
140. (only one side is shown in FIG. 7) is fixed, and two connecting plates (not shown) are fixed at intervals in the longitudinal direction on the back surface of the upper surface shaping plate 14. This is substantially the same as the manner in which the pressing shoe 110 is attached to the slope shaping blade 12 of No. 1, and therefore the explanation of the manner in which the pressing shoe 136 is attached to the upper surface shaping plate 4 is omitted.

Upper surface shaping blade 1 equipped with the above-mentioned pressing shoe 13'6
4 is further equipped with the second slope shaping blade 16. The second slope shaping blade 16 is
Preferably, it is mounted substantially parallel to the cutting edge 122 of the upper surface shaping blade 14 in an adjustable manner (the manner of mounting will be described later). The second slope shaping blade 16 is also shown in FIGS. 1, 2, 3, and 7.
As shown in the figure, the front board 14 has a substantially arc-shaped cross section.
2 and a cutting edge 144 attached to the lower edge of the front board 142.

The cutting edge 144 of the second slope shaping blade 16 extends downwardly and laterally outwardly at a predetermined angle, typically a 45 degree angle, with respect to the horizontal, as shown in FIG. It extends at an angle.

To explain the manner in which the second inclined dust alarm blade 16 is attached to the upper surface shaping blade 14, in the illustrated example, as shown in FIGS. 2 and 7,
The upper part of the back side of the upper surface shaping blade 14 is a connecting body 146.
is fixed.

The connecting body 146 includes an upper plate 148 and a lower plate 150 which are spaced apart in the vertical direction, and a pair of side plates 152 (FIGS. 2 and 7) disposed between the upper plate 148 and the lower plate 150. The upper plate 150 and the lower plate 152 have a plurality of holes 154 (only one side shown in the figure) at appropriate intervals in the lateral direction (therefore, in a direction substantially parallel to the cutting edge 122). In the specific example, 5 pieces) are formed.

The second slope shaping blade 16 has an upper surface plate 158 and a lower surface plate 160 of the connected body 156 positioned between the upper surface plate 148 and the lower surface plate 150 of the connecting body 146 of the upper surface shaping blade 14, and The hole formed in the body 156 and the connecting body 14
6 is aligned with the hole 154 formed in the connecting bottle 164 through the hole of the connecting body 146 and the hole of the connected body.
(Three pieces in the specific example) are attached to the upper surface shaping blade 14.

Since this is the through hole, the second slope shaping blade 16
is moved in the lateral direction (specifically, substantially parallel to the cutting edge 122 of the upper surface shaping blade 14), and a hole 154 formed in the connecting body 146 of the upper surface shaping blade 14 is formed in the connected body 156. This second hole is aligned and the connecting pin 164 is installed.
(Therefore, by moving the second slope surface shaping blade 16 in this way, the ridge shaped by width to the desired value).

Also on the back surface of the second slope shaping blade 16 mentioned above,
As shown in FIGS. 2 and 3, a pressing shoe 166 is attached. The pressing shoe 166 includes an elongated curved plate 168 having a substantially arcuate cross section. Pressing shoe 16 for second slope shaping blade 16
6 is substantially the same as the manner in which the pressure shoe 136 is attached to the upper surface shaping blade 14, and therefore, the manner in which the pressure shoe 166 is attached to the second inclined surface shaping blade 16 will not be explained. Omitted.

Since the first inclined surface shaping blade 12, the upper surface shaping blade 14, and the second inclined surface shaping blade 16 are mounted through the support frame lO, the first fluid pressure cylinder mechanism 82 is expanded (or contracted), the first support member 18 is pivoted upward (or downward) as indicated by the arrow 35 (or arrow 37) about the horizontal axis 26 as described above. When the first support member 1

This can be done by making the pole 20 slidable and hitting the sliding member 220 against the lower stopper 216b of the pole 214;
4, the sliding member 220 is slidable relative to the sliding member 2.
20 against the upper stopper 216a of the pole 214.

The wire member 212 is stretched between the wire hooks 218 of the poles 214 planted at predetermined intervals as described above. The wire member 212 is normally stored on a take-up reel 224 (when not in use), and therefore the wire member 212 is stretched in the following manner, for example. First, the wire member 212 is pulled out from the winding wheel 224, and one end of the wire member 212 is attached to the anchor 2 fixed to the ground.
26 is attached via a jacket 228. Next, while pulling out the wire member 212 from the winding wheel 224, the wire member 212 is attached to the wire hanging portion 2 of one of the poles 214.

12, and then the take-up reel 22 is tightened by a locking member (not shown) provided on the take-up reel 224.
Prevents 40 rotations. Thereafter, the shackle 228 is rotated to apply more tension to the wire member 212. In this way, the wire member 212 is reliably stretched between the wire hooks 218 of the poles 214 (that is, along the longitudinal direction of the ridge to be shaped). Then, one end of the detection arm member 186 of the detection means 170 is hung on the wire member 212 as shown in FIG. You will be guided accordingly.

In the above-described through detection means 170, the wire member 212 (strung between the balls 214 as described above)
When the detection arm member 186 is hung on the wire member 212 in order to detect displacement in the vertical direction with respect to the reference line),
As shown in FIG. 9, the first displacement detection plate 18
One hole among the plurality of holes 184 formed in the detector 198& is located in the detection area 208a of the detector 198 &
Another hole of several holes 184 (in the specific example, detector 1
A second hole 184 located one hole away from the hole 184 opposite the sensing area 208a of the detector 198a is located in the sensing area 208b of the detector 198b (more specifically, the sensing area 20B of the detector 198a is The center of the hole 184 is also located slightly offset from the detection area 208b of the detector 198b, and the detection area 208b of the detector 198b is located slightly closer to the detection area 208a of the detector 198a than the center of the hole 184. It is important that the By doing this, when the tip of the detection arm member 186 is displaced downward (or upward) K by a predetermined amount, the swing arm member 176 moves with the detection arm member 186 to the pin 1.

8b), the first displacement detection plate 182 (D plate portion) is positioned at the detector 198b (or 1
The above-mentioned hole is located in the detection area 208b (or 2osa) of 98a)], thus, as described above, the output signal of the detector 198a (or 198b) changes from rLJ to rH.
It becomes J.

Further, in order to detect displacement in the lateral direction with respect to the wire member 212 (reference line), when the detection arm member 186 is hung on the wire member 212, the detection arm member 186 as shown in FIG. 8-B and FIG. It is important that the second displacement detection plate 192 attached to the other end of the part 186 is located between the detection area 210a of the detector 204a and the detection area 210b of the detector 204b. By doing this, the tip of the detection arm member 186 is
Arrow EI] 188 (or 190) in the figure shows the lateral medial side (
When the detection arm member 186 swings about the pin 187 by a predetermined amount (or laterally outward), the detection arm member 186 swings around the pin 187 to detect the detection area of the detector 204a (or 204b), as shown by the two-dot chain line 192A in FIG. The second displacement detection plate 192 is positioned at z1oa (or 210b), and thus, as described above, the output signal of the detector 204a (or 204b) changes from rLj to rHj. .

In the above-mentioned detection means 170, although not clearly shown, the first displacement detection plate 182 is connected to the eighth
In FIGS. A and 9, a pair of detectors 198a and 198b of the first optical detector 194 are mounted so as to be adjustable in position along the central axis between the detection areas 208a and 208b, and a second displacement detection The plate 192 is aligned with the central axis between the sensing areas 210a and 210b of the pair of detectors 204a and 204b of the second optical detector 196 in FIGS. 8-B and 10, that is, the rear end axis of the sensing arm member 186. It is mounted so that its position can be adjusted along the central axis. Therefore, as described above, by changing the position of the first displacement detection plate 182, the accuracy in the vertical direction of the shaped ridge (that is, the ridge height accuracy) can be adjusted. It will be understood that the lateral accuracy of the shaped ridge (that is, the vertical accuracy of the ridge) can be adjusted by changing the position of the displacement detection plate 192.

The first optical detector 194 (and thus the detector 198

34 is switched, supplying pressure fluid to the output side of the hydraulic cylinder mechanism 82 of the furnace 1 and returning pressure fluid to the base side of the first hydraulic cylinder mechanism 820, thus
The hydraulic cylinder mechanism 82 of is contracted. Also,
When the cylinder extension signal is sent to the electromagnetic solenoid 236b, the electromagnetic solenoid 236b is energized, the direction control valve 234 is switched, and pressure fluid is supplied to the base side of the first fluid pressure cylinder mechanism 82, and the first The pressure fluid on the output side of the hydraulic cylinder mechanism 82 is returned, and the first hydraulic cylinder mechanism 82 is thus expanded.
A cylinder contraction signal and a cylinder expansion signal are also generated based on the output signal of 6 (in detail, a cylinder contraction signal is generated when the output signal of the detector 204a is rLJ and the output signal of the detector 204b is rHJ, , detector 20

38 is switched, supplying pressure fluid to the output side of the second hydraulic cylinder mechanism 84 and returning pressure fluid to the proximal side of the second hydraulic cylinder mechanism 84, thus
The hydraulic cylinder mechanism 84 of is contracted. Also,
When the cylinder extension signal is sent to the electromagnetic solenoid 240b, the electromagnetic solenoid 240b is energized and the directional control valve 238 is switched, and pressure fluid is supplied to the base side of the second hydraulic cylinder mechanism 84 and the second The pressure fluid on the output side of the second hydraulic cylinder mechanism 84 is returned, thus causing the second hydraulic cylinder mechanism 84 to expand.

In addition, the electromagnetic lens 236 of the directional control valve 234 mentioned above
a and 236b and the electromagnetic solenoids 240a and 240b of the directional control valve 238 are configured to be energized also by operating a control lever (not shown) provided at the driver's seat of the bulldozer 8. Therefore, by operating this operating lever, the direction control valve 23
4 and 238, the first hydraulic cylinder mechanism; js2 and the second hydraulic cylinder mechanism 84 can be contracted and expanded.

On the back of the blade 6 of the bulldozer 8 on which the above-mentioned ridge shaping device 2 is installed, three pressing shoes 242 (
(Two shown in the drawing) are installed. All three pressing shoes 242 have approximately the same configuration, and the pressing shoes 242 have approximately the same configuration.
42 includes an elongated curved plate 244. A pair of slope plates 246 are fixed to the curved plate 244 at the middle part of the upper surface thereof with a slight interval in the longitudinal direction. On the other hand, at the lower end of the back surface of the blade 6, there are connecting plates 248 (connecting plates) 248 (
(only one shown in FIG.
A pair of connecting brackets 250 and 252 (in FIG. 3, a pair of connecting brackets 25
0 and 252 (only one side of which is shown) is fixed. Then, on each of the connecting plates 248,
The front ends of a pair of glue brakes 4246 of each pressing shoe 242 are rotatably connected, and both ends of a place 254 are connected by a pin between each of a pair of connection brackets 250 and each of a pair of glue plates 246. ing. Thus, each of the pressure shoes 242 is held in the position shown in FIG. 3 by a respective place 254. The above-mentioned place 254 corresponds to the above-mentioned description and the third
As understood from the figure, it is also possible to connect to a pair of connecting brackets 252, and two holes for connection are formed at one end of the place 254, as shown in FIG. Therefore, each of the pressing shoes 242 can be positioned (specifically, between the connecting plate 248 and the pair of rib plates) by changing the way in which the pair of connecting brackets 250 and 252 are connected to one end of the place 254, respectively. 246, the position can be changed by pivoting around the connecting portion of 246. A side plate 256 (only one side is shown in FIGS. 1 to 3) is further attached to both side edges of the blade 60 and projects forward.

Next, the effects of the ridge shaping device 20 as described above will be explained with reference mainly to FIGS. 1 to 3. When shaping ridge soil (substrate) with a roughly semicircular or semi-elliptical cross section into a ridge with a trapezoidal cross section using the ridge shaping device 2 mounted on the bulldozer 8, first The lever 134 is manually rotated to adjust the position of the upper surface shaping blade 14 with respect to the first inclined surface shaping blade 12, and thus the vertical position of the upper surface shaping blade 14 is adjusted to a predetermined position. setting (as will be understood from the description below, the height from the lateral inner edge of the cutting edge 108 of the first slope shaping blade 12 to the lower edge of the cutting edge 122 of the upper surface shaping blade 14 is shaped). Therefore, the height of the ridge is set by adjusting the position of the upper surface shaping blade 14). Next, the second inclined surface shaping blade 16 is moved laterally with respect to the upper surface shaping blade 14,
By connecting the two using a connecting pin 164 (FIG. 7), the position of the second slope shaping blade 16 with respect to the upper surface shaping blade 14 is adjusted, and thus the position of the second slope shaping blade 16 is adjusted. Set the horizontal and lateral position to a predetermined line (as understood from the description below,
From the intersection of the lower edge of the cutting edge 108 of the first inclined surface shaping blade 12 and the lower edge of the cutting edge 122 of the upper surface shaping blade 14 to the lower edge of the cutting edge 122 of the upper surface shaping blade 14 and the second Cutting edge 144 of slope shaping blade 16
Since the width of the upper surface of the shaped ridge is determined by the width of the upper surface of the ridge, the width of the upper surface of the ridge is set by adjusting the position of the second slope shaping blade 16. ).

After that, the bulldozer 8 is positioned on one side of the ridge soil so that it is approximately parallel to this, and the first hydraulic cylinder is operated by operating a control lever (not shown) provided on the driver's seat. Mechanism 82 and second fluid pressure cylinder mechanism 8
4, the rotation angle of the first support member 18 about the horizontal axis 26 is adjusted to set the vertical position of the first inclined surface shaping blade 12 as required. (generally, the lateral inner end of the cutting edge 108 of the first slope shaping blade 12 is set to substantially match the lower end (base surface) of the ridge soil), and the detection means 170 One end of the detection arm member 186 is hung on the wire member 212 stretched along the longitudinal direction of the ridge soil as described above (the wire member 2
When the detection arm member 186 is hung on the 9th
As shown in the figure and FIG. 10, one hole among the plurality of holes 184 formed in the first displacement detection plate 182 is located in the detection area 208a of the detection ia 498m, and the plurality of holes 184 Another hole in my house is detector 19.
8b, and the second displacement detection plate 192 is located in the detection area 210 of the detector 204a.
a and the detection area 210b of the detector 204b). In this way, the first slope shaping blade 12, the upper pear-shape blade 14, and the second slope shaping blade 16 are made to act on the ridge soil, blowing it, and shaping the ridge. It becomes possible to perform ridge shaping work.

In this state, the bulldozer 8 is moved forward along the longitudinal direction of the ridge soil. If you hide it,
One slope of the ridge (the slope on the bulldozer 8 side) is shaped by the cutting action of the first slope shaping blade 12, and the upper surface of the ridge is shaped by the cutting action of the upper surface shaping blade 14. Ma'fc second slope shaping blade 14
By the cutting action, at least a portion (or all) of the other sloped surface of the ridge (the sloped surface opposite to the bulldozer 8 side) is shaped. Furthermore, the first slope shaping blade 12
The pressing shoe 110 is pressed against one slope of the ridge that has been shaped, and the pressing shoe 136 is pressed against the upper surface of the ridge that has been shaped by the upper surface shaping blade 14. The pressing shoe 166 presses against the other inclined surface of the ridge shaped by the inclined surface shaping blade 16, and the one inclined surface, the upper surface, and the other inclined surface of the ridge thus shaped are respectively flattened. Ru.

During such ridge shaping work, for example, if the bulldozer 8 curves to the right (therefore, in the direction of approaching the ridge earth and sand) (when the bulldozer 8 is moved forward along the ridge earth and sand, the bulldozer 8 On one side of the bulldozer 8, the first slope shaping blade 12, the upper surface shaping blade 14, and the second slope shaping blade 16 act on the ridge soil, causing a so-called unbalanced load to act on one side of the bulldozer 8. , the bulldozer 8 tends to curve in a direction that gradually approaches the ridge soil as it moves forward (or if it curves to the left, the VC) has a detection arm member 186 (Fig. 8-A and Figure 8-B) is shown by arrow 188 (or 190) in Figure 8-B.
When the rotation angle is greater than or equal to a predetermined value, the detector 204a of the second optical detector 196
(or 204b) detection area 210a (or 210b)
The second displacement detection plate 192 is positioned at (Figures 81 and 10). When hidden, the detector 204
The output signal of a (or 204b) changes from rLJ to rHJ (at this time, the output signal of the other detector 204b (or 204m
) remains "L" as described above], the output signal 1"3 of the detector 204a (also Fi, 204b) and the output signal "L" of the detector 204b (or 204m) Based on this, a cylinder extension signal (or cylinder contraction signal) is generated in the control means 172 (FIG. 11), and the hydraulic cylinder mechanism 84 of M2 is extended (or contracted) as described above.

When the second fluid pressure cylinder mechanism 84 is extended (or contracted), the first inclined surface shaping blade 12 moves laterally inward (or Laterally outward) [therefore, in the direction approaching (or away from) the bulldozer 8], and thus the first inclination is The surface shaping blade 12, the upper surface shaping blade 14, and the second slope shaping blade 16 are moved substantially straight forward along the ridge soil. Therefore, one slope, the top surface, and the other slope of the ridge can be straightened as required (the @ line accuracy of the ridge can be improved)
. In addition, as described above, it is preferable to extend the second fluid pressure cylinder mechanism 84 almost to the maximum at the start of moving the bulldozer 8 forward along the ridge soil. Probably.

On the other hand, if, for example, the bulldozer 8 moves upward (or downward) during such ridge shaping work (for example, if the field base on which the bulldozer 8 runs has unevenness, the bulldozer 8 moves up and down due to the unevenness). The detection arm member 186 (FIGS. 8-A and 8-B) pivots downward, which is counterclockwise in FIG. 8-A (or upward, which is clockwise in FIG. 8-A). and the detection arm member 1
A swing arm member 176 is rotated integrally with 86 in the direction shown by an arrow 178 (or 180) in Fig. aE8-A,
When this turning angle exceeds a predetermined value, the detection area 2 of the detector 198 & (or 198b) of the first optical detector 194
Q 13 a' (or 208b) (Fig. 9) has the first
A portion of the plate 1 of the displacement detection plate 182 is positioned. When this happens, the output signal of the detector 198a (or 198b) changes from rLJ to rHJ (at this time, the output signal of the other detector 198b (or 198a) remains "L" as described above). , detector 198

The hydraulic cylinder mechanism 82 of is contracted (or expanded'j*). When the first hydraulic cylinder mechanism 82 is retracted (or expanded), the first inclined surface shaping blade 12 moves as indicated by the arrow 165 (or 16.3 in FIG. 3), as described above.
), and thus, even though the bulldozer 8 moves forward by moving in the vertical direction with respect to the ridge earth and sand, the first slope shaping blade 12, The upper surface shaping blade 14 and the second slope shaping blade 16 are advanced at substantially the same height relative to the ridge shaping earth and sand. Therefore, the height of the ridge can be shaped to be substantially the same height along its longitudinal direction (the height accuracy of the ridge can be improved)
.

Furthermore, in the bulldozer 8 equipped with the above-mentioned ridge shaping device 2, when moving forward, the pressing shoe 242 attached to the back surface of the blade 6 is pressed against the field base on which the bulldozer 8 is traveling. The field foundation will also be leveled. Therefore, by flattening this field base, it is possible to further reduce the negative effect on the precision of the shaped ridges, especially on the height and roughness.

In addition, a bulldozer 8 equipped with the above-mentioned ridge shaping device 2
As can be understood from the above description, when the bulldozer 8 moves forward, an unbalanced load acts and the first support member 18 is elastically deformed upward in FIG. The guide protrusion 52 (specifically, the side gB plate 54 located on the upper side in FIG. 5) is attached to the side surface of the guide member 700 and the guide groove 68 (the side plate 78 located on the upper side in FIG. 5). Thus, the unbalanced load is transmitted to the main body of the bulldozer 80 via the first support member 18, the guide member 70, the support body 58, and the bush arm 4. - Therefore, damage to the connecting bin 34 and deformation of the blade 6 can be prevented, and the above-mentioned unbalanced load acts near the center of gravity of the bulldozer (normally, one end of the bush arm 4 can be freely pivoted near the center of gravity of the main body of the bulldozer 8). (Therefore, the uneven load acts on the vicinity of the center of gravity of the bulldozer 8 via the bush arm 4.) Therefore, meandering of the bulldozer 8 due to the uneven load can also be suppressed.

Furthermore, a bulldozer 8 equipped with the above-mentioned ridge shaping device
, a first slope shaping blade 12, an upper surface shaping blade 14, and a second slope shaping blade 16.
are arranged so that they are located within the range of the ground-contacting part of the track-tracking device 9. Therefore, the pitching that occurs when the bulldozer 80 runs (mainly, the pressing shoe 242 attached to the back of the blade 6 touches the field base) blades 12.14 and 1)
6 can be reduced in vertical movement, and it becomes possible to further improve the accuracy of the ridge.

On both sides of the slope of the ridge shaped as described above,
Surplus soil cut by the first slope shaping blade 12 and surplus soil cut by the second slope shaping blade 16 are left behind. 82, the first slope shaping blade 12, the upper surface shaping blade 14, and the second slope shaping blade 16 are positioned upward, and the bulldozer 8 is again moved along the longitudinal direction of the shaped ridge. By moving the blade 6 forward, soil is removed by the action of the side plate 256 attached to the side edge of the blade 6.

Although one specific example of the ridge shaping device constructed according to the present invention has been described in detail above, the present invention is not limited to such a specific example, and various cyst-shaped and Modification is possible.

For example, in a specific example, the pressing blades SL, -11 attached to each of the first slope shaping blade 12, the upper surface shaping blade 14, and the second slope shaping blade 16 are
0, 136 and 166 are configured to be pressed by their own weight against one sloped surface, the top surface and the other sloped surface of the ridge, respectively, or to increase this pressing force to further flatten each surface. This is also possible by configuring it as shown in FIG. For example, the first slope shaping blade 12 will be explained with reference to FIG. 13 (the upper surface shaping blade 14 and the second slope shaping blade 16 may be configured in substantially the same manner). Pressing shoe 11
0 is equipped with an elongated curved plate 112, and on the upper surface of the curved plate 112, a pair of rib braces (114) are provided at each of three longitudinally spaced positions and at a slight distance from each other in the longitudinal direction. (In FIG. 13, only one of the three sets of climb plates 114 is shown) is fixed. On the other hand, on the back side of the first slope shaping blade 12, three
A connecting plate 132 and a connecting bracket 300 are fixed to each of the three positions. A front end portion of a pair of glue plates 114 is rotatably connected to each of the connecting plates 132 by a connecting pin 118. On the other hand, a through hole is formed in the upper wall 302 of each of the connection brackets 300, and a shaft portion of a bolt 304 is inserted into the through hole. A compression spring 306, a washer 308, and a nut 310 are installed in this order on the shaft of the bolt 304. Further, a connecting piece 312 is screwed onto the tip of the bolt 304. The intermediate portions of the pair of sliding plates 114 are rotatably connected to the lower end of the connecting piece 312 by a connecting pin 314. With the structure as described above, the pressing shoe 110 is pressed against the sloped surface of the ridge with the required pressure by the action of the compression spring 306, thus making it possible to further flatten the ridge.

This configuration is substantially the same as the configuration disclosed in the specification and drawings of Japanese Patent Application No. 128181/1981 (name: ridge shaping device) filed on August 18, 1981. , for details 1l-1, patent application 1984-12
