[0002]
[Prior art]
Conventionally, as a scraping work machine, soil is cultivated while rotating a scraping rotor formed by attaching a plurality of scraping claws to a tilling shaft in a direction from the top to the bottom (forward direction) with respect to the ground. Things are common.
[0003]
In addition, it is necessary not only to crush rough soil blocks finely and level the ground level, but also to bury the soil and dirt in the cultivated soil in the soil. The rear cover is provided with a spring rake in order to bury these impurities deeply in the soil.
[0004]
[Problems to be solved by the invention]
In the above-mentioned conventional device, the cutting rotor is rotated in the forward rotation direction so that the cultivated soil is dissipated backward. However, there is a problem that they cannot be sufficiently buried in the soil simply by holding them with the rear cover, and even if a spring rake is provided, there is a risk of traps and foreign objects being caught by this spring rake. Yes, the leveling marks after scraping are not beautiful, and in order to finish it neatly, it is necessary to perform repeated scraping work so that rice straw etc. does not come out on the surface, which takes time and greatly reduces work efficiency I was letting it.
[0005]
[Means for Solving the Problems]
The present invention is simple in structure and can reliably bury the dirt and other impurities in the soil, and does not eat much horsepower during the cutting operation, and the finishing operation is completed in a small number of times. Therefore, the present invention has taken the following technical means.
[0006]
That is, the invention of claim 1 covers the covering nail (6) and the nail shaft (5) while rotating the nail shaft (5) having the nail claw (6) from the bottom to the top with respect to the ground. rotate toward the rear from the front of the rotary cover (9), and configured to perform Dai掻by synergy between the leading edge lower portion of the rotary cover while forces the mud forward by cash掻爪(6) (9) A reinforcing pipe (8) is provided at the lower end of the front edge of the rotary cover (9), and the rear part of the reinforcing pipe (8) is closest to the cutting claw (6). The distance from the inside of the cover (9) is such that the front side is narrow and widens toward the rear side, and a secondary rotary cover (10) is provided at the rear of the rotary cover (9). 10) a pressure plate (14) is formed at the rear of the auxiliary rotor Was Dai掻apparatus characterized by comprising comb teeth-shaped tooth body (40) between the cover (10) and put down plate (14).
[0007]
According to a second aspect of the present invention, the tooth body (40) is configured to swing back and forth about the fulcrum (42), and the back and forth swing of the tooth body (40) drives the claw shaft (5) to rotate. It was comprised so that it might drive from the input shaft (3) to do. It was set as the substitute apparatus of Claim 1 characterized by the above-mentioned .
[0008]
The operation of claim 1 will be described. The cutting work machine is connected to the rear part of the tractor so as to be movable up and down, and the power on the tractor side is transmitted to the input shaft on the cutting work machine side to reverse the cutting claw shaft. The rotation direction of the nail claw shaft rotates from the bottom to the top with respect to the ground and from the front to the rear of the rotary cover that covers the nail claw and the nail shaft. Then, the nail claw attached to the nail claw shaft cuts out the soil together with water and releases it to the back while carrying it around the inside of the rotary cover.
[0009]
At this time, mud by cash掻爪reversing is relegated to the front, the water is accumulated state prior subgingival portion of the rotary cover. In a state where there is a lot of water, soil, rice plants, etc. are kneaded by claw claws, and finely crushed between the reinforcing pipes and muddy water passes through the part closest to the inside of the rotary cover and is discharged backwards, Soil and rice stocks with high specific gravity pass below (the side closer to the nail shaft) and are released back. For this reason, large soil blocks and rice stocks are deposited in the lower layer, and fine soil and water are deposited thereon, so that rice straw and the like do not appear on the surface, and the work marks can be made beautiful.
In addition, it is possible to satisfactorily embed impurities in the soil by the tooth body.
[0010]
The effect of claim 2 is that, in addition to the effect of claim 1, when the tooth body is swung back and forth, the crushed property of the soil lifted in the rotary cover is enhanced, and the ability to bury impurities is remarkably improved. To do.
[0011]
Embodiment
Embodiments of the present invention will be described below based on the embodiments shown in the drawings. First, the construction will be described. In FIG. 1, reference numeral 1 denotes a rotary scraping work machine having a predetermined length in the left-right direction, and is connected to the rear part of the tractor (not shown) so as to be movable up and down via a three-point link mechanism. .
[0012]
Power is transmitted from the PTO shaft (not shown) of the tractor to the input shaft 3 of the scraper working machine 1 via the universal joint 2, and in the transmission case 4 provided on the side of the working machine. The claw shaft 5 is rotated through a chain / sprocket mechanism or the like sequentially.
[0013]
The rotation direction of the claw shaft 5 is set so as to be the reverse direction (the direction of arrow A in FIG. 1) in which the claw 6 is directed from the bottom to the top with respect to the ground. A plurality of cutting claws 6 are detachably attached to the cutting claw shaft 5. A cultivation claw and a crushing claw are attached in place of the cutting claw 6, and the rotation speed of the claw shaft is changed to perform the cultivation work. It is also possible to perform crushed earth work.
[0014]
A rotary cover 9 having a circular arc when viewed from the side is provided to cover the rotary part above the rotary part constituted by the primary claw shaft 5 and the alternative claw 6, and the rotary cover 9 has a lower front edge at the ground surface. A hollow pipe 8 is extended in the horizontal direction as a reinforcing frame at the lower end. By providing the reinforcing pipe 8 at the lower end edge of the rotary cover 9 in this manner, stones, earth clots, wood chips and the like are prevented from entering the rotary cover 9, and the reverse claw 6 and the pipe 8 are used to cut off the metal. The nail | claw 6 is trying to raise the crushed property at the time of cutting a soil.
[0015]
As is clear from FIG. 1, the rear portion of the reinforcing pipe 8 is closest to the claw claw 6, and the starting end portion of the rotary cover 9 is configured to start from a location slightly away from the front side. Then, the gap between the rotation trajectory of the succeeding claw 6 and the inner side of the rotary cover 9 is set so as to be narrow at the front side and widen toward the rear side.
[0016]
Further, a sub-rotary cover 10 capable of adjusting the angle is attached to the rear portion of the rotary cover 9. The auxiliary rotary cover 10 can be adjusted in its mounting angle around the fulcrum 12. In this embodiment, the tilt angle can be adjusted thereafter by turning the turnbuckle 13.
[0017]
The adjusting method of the sub rotary cover 10 is not limited to this embodiment, and an angle adjusting rod is attached to the lower end edge of the sub rotary cover 10 instead of the turnbuckle 13, and the end of the angle adjusting rod is attached. May be provided with a screw, and the angle adjusting rod may be inserted into a long hole provided on the frame side and tightened with a nut after the angle adjustment to fix the angle adjusting rod.
[0018]
Incidentally, when the Dai掻work, but use of this auxiliary rotary cover 1 0 Fixed to the appropriate angle, the applicant actually imaginary extension and the ground surface of the auxiliary rotary cover 1 0 crosses was confirmed It was found that the angle B formed was 50 ° to 70 °, preferably 55 ° to 65 °.
[0019]
If the angle B is increased beyond this range, the clumps and rice plants that have been crushed by the claw 6 are re-rolled into the rotating part without being released back, resulting in the consumption of a large amount of horsepower. On the other hand, if the secondary rotary cover 13 is laid down and the angle B is reduced, there is a problem that foreign matter such as rice stocks and straws, and clods float on the surface of the water, and the appearance is not good and it is difficult to make the finished mark beautiful. It was. However, if the angle is within the above range, the lump, the rice stock and the like carried around in the rotary cover 9 at the time of the cutting work are buried in the soil by centrifugal force, and fine mud and water accumulate on it, resulting in a finished trace. It's beautiful.
[0020]
In this embodiment, the interval between the rotation trajectory of the reinforcing pipe 8 and the claw claw 6 at the lower end of the rotary cover 9 is set to about 5 mm. Thus, the interval between the rotary cover inlet portions is narrowed. This prevents large stones and hard clots from being caught. According to the applicant's confirmation, there is no hindrance to the suction of muddy water even at such an interval, and the soil mass carried upward by the rotating claw 6 can be further finely crushed with moisture absorbed. all right.
[0021]
In FIG. 1, reference numeral 14 denotes a pressure-reducing plate pivotally attached to the square pipe 15 about a fulcrum 18 as a center. The pressure-reducing plate 14 is pressed downward by arm rods 16 and 16 projecting rearward from the square pipe 15 and a pressure bar 17 hanging from the arm rods 16 and 16. Since the pressure-reducing plate 14 is constantly urged downward in this manner, the bottom surface can press the ground surface evenly.
[0022]
A flat plate 20 is pivotally mounted around the fulcrum pin 22 at the rear portion of the pressure plate 14 so as to be swingable up and down, and a spring rake 24 for embedding impurities in the soil is provided in the width direction below the flat plate 20. A plurality are provided along. At the time of scraping work, the front portion of the flat plate 20 is slightly raised and used, and is pressed by the spring rake 24 while sending foreign matters backward.
[0023]
The leveling plate 20 is used not only for leveling work but also for earthing work. An intermediate portion of a rod 26 is pivotally attached to an arm 25 projecting from the square pipe 15. The lower end of 26 is pivotally attached to the flat plate 20. Another rod 27 is pivotally attached to the upper end of the rod 26 along the front-rear direction. A handle 30 is provided at the tip of the rod 27, and an operator grips the handle 30 while riding on the tractor and appropriately attaches it. When operated, the angle of the flat plate 20 is changed.
[0024]
For example, when the handle 30 is pushed rearward, the leveling plate 20 stands up via the rods 27 and 26, and the earthing work can be performed using the front surface of the leveling plate 20. In the figure, reference numerals 32 and 32 are side plates provided on the left and right sides of the gear case 33 that supports the input shaft 3, 34 is a rotary mast on the rotary scraper 1 side, and 35 is a quick hitch mounted on the tractor side. Reference numeral 36 denotes a top link, in FIG. 2, reference numeral 37 denotes a side plate, and 38 denotes a connect pipe.
[0025]
Next, the configuration of the rotary machining apparatus shown in FIG. 3 will be described.
The substitute working machine described in this figure is an improved part of the construction of the working machine described in the above embodiment. Components that are the same as those in the above-described embodiment are denoted by the same reference numerals, and completely new configurations are denoted by different symbols to describe the configurations.
[0026]
The difference in configuration between the two is that the angle adjustment of the secondary rotary cover 10 can be performed in the former, but the angle adjustment cannot be performed in the latter, and the comb-tooth-like tooth body 40 that is not present in the former. Is provided in the latter.
The tooth body 40 is provided in the width direction by the same length as the plowing width behind the cutting nail shaft 5, and is configured so that the whole can swing back and forth around the fulcrum 42.
[0027]
A rotating disc 41 is provided on the side of the side plate 32, and an eccentric cam 43 is provided at a location deviated from the center position of the disc 41. The tooth body 40 is placed on the eccentric cam 43 in the front-rear direction. One end of a rod 44 for rocking in small increments is connected to the other end, and the other end of the rod 44 is connected to the upper end of the tooth body 40.
[0028]
The power transmission to the rotating disk 41 may be taken directly from the input shaft 3. For example, as shown in FIG. 4, another output shaft 45 is provided on the opposite side of the input shaft 3, and the bevel gear is connected to the output shaft 45. The rotating disc 41 is transmitted to the horizontal shaft 47 via the mechanism 46 and the like, and further, the chain sprocket mechanism 48 provided at the outer end portion of the horizontal shaft 47 is transmitted to the second horizontal shaft 49 and fixed to the end portion of the second horizontal shaft 49. May be configured to be driven. The tooth body 40 may be configured to swing back and forth about one fulcrum as a whole. However, the tooth body is divided into two sets, one set is fixed, and the remaining tooth body is swung back and forth. You may make it carry out burial processing of the foreign substance by the cooperation action of a tooth body.
[0029]
Next, the operation of the embodiment will be described.
When performing a chamfering operation, the chamfering machine 1 is connected to a tractor and enters the field, and each rotating unit is driven to advance the machine body. When the rotational power on the PTO shaft side of the tractor is transmitted to the input shaft 3 via the universal joint, the rotational power is transmitted to the scratching claw shaft 5 via the chain sprocket mechanism in the transmission case 4 and the reverse rotation amount. The soil is lifted upward by the nail 6. At the same time, the muddy water is driven forward and scraped in a state where a large amount of water is accumulated inside the reinforcing pipe 8 at the lower front edge of the rotary cover 9. At this time, since the gap formed by the reinforcing pipe 8 below the rotary cover 9 and the rotation trajectory of the claw claw is very small, large clots or stones do not enter the gap and clogging occurs. Since it does not occur, the chamfering operation can be smoothly performed without being interrupted.
[0030]
In addition, the large clot is reliably crushed by the reverse claw 6 and even if it is dissipated backward in the rotary cover, the gap formed by the rotary cover and the rotation trajectory of the claw 6 is larger on the rear side than on the front side. Since it gradually increases in size, it does not consume horsepower during work, and large soil blocks and rice straw accumulate on the lower layer, and small soil and muddy water accumulate on it. The finish will be beautiful later.
[0031]
In particular, in the present invention, the angle formed by the virtual extension line of the rear end of the rotary cover 9 and the ground intersecting is set to 50 ° to 70 °. There is a feature that the entrainment is reduced, or there is a feature that the scars are cleaned by satisfactorily embedding rice straw, foreign matter, etc. scattered in the rear into the soil.
[0032]
【The invention's effect】
Since the present invention is configured as described above, the following technical effects can be obtained.
That is, the invention of claim 1, even with a small water in the field because reversal allowance掻爪in rotary cover front edge bottom portions acting has become water often state with crushing soil is improved Dai掻Work can be performed smoothly.
[0033]
In addition, without having to intrude large stones and clods at the time to guide the soil in the cover die掻爪to reverse rotation, even if the bite crowded in cover since the frame is secured even in the lower rotary cover damage deformation There is little fear to do.
[0034]
In addition, there is little resistance when the cut soil is finely crushed and released to the rear, and most of the soil that is cut up by the claw claw and lifted upwards is quickly released to the outside of the rotary cover after crushing. Since dirt such as clumps and rice stocks are buried in the soil, the soil does not collect on the front of the rotary cover as in the past, and efficient cutting work can be performed without consuming horsepower. it can.
[0035]
Moreover, since the comb-tooth-like tooth body is provided between the sub rotary cover and the pressure plate, it is possible to satisfactorily embed impurities in the soil.
[0036]
In addition to the effect of the first aspect , the invention of claim 2 is configured such that the tooth body can swing back and forth about a fulcrum, and the tooth body swings back and forth as an input shaft for rotationally driving the claw shaft. Therefore, the crushed property of the soil lifted in the rotary cover is enhanced, and the burying ability of the foreign matter is remarkably improved.
