In addition, environmental problems can be avoided even in the case of incineration and disposal due to being made of paper. Furthermore, since the paper covering the ridges is in a state of being stuck to and adhered to the soil on the surface of the ridges, weeds can be better prevented from growing from the ridges than before, and the paper and ridge surface It is difficult for the paper to break due to the wind entering between the papers, so that thinner paper can be used than conventional paper mulch simply covered on the ridge, and the material cost can be reduced.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The example shown in FIG. 1 and FIG. 2 has a configuration in which a ridge device 2 and a ridge surface layer processing device 13 provided with a liquid spraying means and a rotating body 18 are attached to the rear part of a self-propelled vehicle body 1 such as an agricultural tractor. belongs to.
[0012]
The ridge device 2 is mounted on a link device 2 provided at the rear of the self-propelled vehicle body 1. The link device 2 is configured to be able to be driven up and down via left and right lift arms 3 and 3 and lift rods 4 and 4. The configuration of the ridger 2 includes a central transmission case 5 to which power is transmitted from a PTO shaft (not shown) of the self-propelled vehicle body 1 via a universal joint, a frame 6 attached to the central transmission case 5, A tilling transmission case 7 extending downward from the case 5, a tilling device 10 including a tilling shaft 8 and a tilling claw 9, below the tilling transmission case 7, and a tilling that covers the upper portion of the tilling device 10. It has a configuration including a cover 11 and left and right ridge forming plates 12, 12 disposed on the left and right sides on the rear side of the tillage device 10.
[0013]
The ridge surface layer processing device 13 is provided so as to perform a ridge surface layer portion processing function behind the ridge raising device 2. In this example, specifically, a left transmission frame 14 extending leftward from the center transmission case 5 of the ridger 2, a left transmission case 15 extending rearward and downward from an end of the left transmission frame 14, The right transmission frame 16 extending rightward from the center transmission case 5, the right transmission case 17 extending rearward and downward from the end of the right transmission frame 16, the left transmission case 15, and the lower end of the right transmission case 17. A rotating body 18 is mounted between the left and right so as to be rotatable for driving. The rotating body 18 has an outer peripheral surface having a shape conforming to the ridge upper surface shape formed by the ridger 2, and has a thrust-like shape as a whole, and a small-diameter cylindrical portion corresponding to a central surface layer portion of the ridge. 18a, and large-diameter cylindrical portions 18b, 18b which are provided on both left and right outer sides of the small-diameter cylindrical portion 18a and correspond to the left and right inclined portions and the right and left groove portions, respectively. Then, the rotating body 18 rotates while being contacted with the ridge surface layer by the power in the central transmission case 5 being transmitted, and the rotating body 18 has a circumference higher than the speed at which the rotating body 18 moves along the ridge by the self-propelled body 1. The rotating body 18 rotates at high speed in a direction in which the lower peripheral surface of the rotating body 18 moves from the front side to the rear side. It should be noted that if the rotation speed of the rotating body 18 is configured to be appropriately changeable, or if the rotating body 18 is configured to reversely rotate in a direction in which the lower peripheral surface of the rotating body 18 moves from the rear side to the front side, different soils may be used. Can be improved.
[0014]
The ridge surface layer processing device 13 further includes a liquid spraying unit. In this example, the liquid spraying means is, specifically, a liquid tank 19a provided at the rear of the self-propelled vehicle body 1, a supply hose 19b for supplying liquid from the liquid tank 19a to the pump 20a, and a liquid in the liquid tank 19a. , A transfer hose 20b for sending the liquid discharged from the pump 20a to the spray nozzles 21,..., And a liquid sprayed on the peripheral surface of the rotary body 18 with a predetermined interval left and right above the rotary body 18. . Are provided. The liquid is sprayed from the spray nozzles 21,..., At the lower end of the rotating body 18 or at a position in front of it, or as shown in FIG. It is provided so as to be scattered on the surface. If the liquid is sprayed at the lower end portion of the rotating body 18 or at a position in front of it (in the direction in which the rotating body 18 moves along the ridge), the soil ridge is considerably dry and has very little moisture. On the other hand, there is an advantage that a sufficient amount of liquid can be sprayed and the processing operation can be performed well. When the liquid is sprayed on the outer peripheral surface of the rotating body 18, the mud attached to the outer peripheral surface of the rotating body 18 can be washed away, and the mud is less likely to accumulate on the outer peripheral surface of the rotating body 18. Has the advantage of being able to continue well. The liquid to be sprayed may be water, but if a herbicide is mixed with the water, the herbicidal effect of the ridge can be further enhanced. In addition, if a coagulant and a pulp solution are mixed, collapse of the surface layer of the ridge treated in the form of the clay after drying is less likely to occur, and collapse of the ridge is suppressed, so that the cultivation operation can be performed satisfactorily.
[0015]
As a result, the soil of the ridge surface layer contacting the rotating body 18 becomes wet with the liquid sprayed from the spray nozzles 21,..., And the soil of the ridge surface layer in this state comes into contact with the outer peripheral surface of the rotating body 18. When the outer peripheral surface of the rotating body 18 moves to the front side or the rear side while making contact with the ridge surface layer, the ridge surface layer is processed into a clay shape.
[0016]
The above configuration operates, for example, as follows. When the self-propelled vehicle body 1 is made to travel forward while rotating various parts of the body, the soil in the field is plowed by the tilling device 10 of the ridger 2, and wide ridges are formed by the left and right ridge forming plates 12, 12. Then, the rotating body 18 rotates at a high speed in a direction in which the lower peripheral surface of the rotating body 18 moves from the front side to the rear side while the rotating body 18 contacts the surface portion of the ridge. The liquid in the liquid tank 19 is sent by a pump, is ejected from the spray nozzles 21, and is sprayed over the entire left and right widths of the outer peripheral surface of the rotating body 18. Since the outer peripheral surface of the rotating body 18 rotates at a high speed while being in contact with the surface of the ridge in a state of being coated with the sprayed liquid, the soil on the surface of the ridge that the rotating body 18 contacts is processed into a clay form. Therefore, while the ridge work is being performed, the soil on the surface layer of the ridge is processed in a kneaded state. The ridge on which such work has been performed is in a state in which the surface is coated with mud. Therefore, when the ridge surface layer portion treated in the form of the clay is dried, the mud becomes hard as when the mud is dried, and the ridge surface is in a state where the ridge is covered with a dense and hard soil plate.
[0017]
Therefore, weeds can be effectively suppressed from growing from the ridges without covering the ridges with the multi-sheet as in the prior art, eliminating the work of removing the multi-sheets, reducing the labor required for agricultural work, and environmental problems at the time of multi-sheet disposal. Will be eliminated. In addition, the ridges whose ridge surface layer has been treated as described above suppress the evaporation of water and improve the water retention of the ridges, and furthermore, the lower layers of the ridges are not solidified and are kept in a soft state. , And can grow crops well.
[0018]
Further, in the above-mentioned construction, the work for treating the ridge surface layer portion in the form of the kneaded soil can be performed efficiently together with the ridge work, and the ridge surface layer processing device 13 is set to the ridge device 2. Since the structure is supported at the height, the rotating body 18 of the ridge surface layer processing device 13 can act on the ridge formed by the ridge device 2 by bringing the rotator 18 into contact with the ridge surface layer so that the ridge is not excessively compacted. It is possible to process the ridge surface layer portion in the form of a clay and the lower layer portion in a state where it is not compacted. Although not shown, a rotator height adjusting mechanism for changing the vertical position of the rotator 18 of the ridge surface layer processing device 13 with respect to the ridger 2 is provided. The contact state with respect to the ridge surface layer can be changed as appropriate in the up-down position, so that a good processing operation can be performed. If the ridge device 2 is not provided on the self-propelled vehicle body 1 and only the ridge surface layer processing device 13 is mounted, prior to performing the ridge surface layer processing operation by the ridge surface layer processing device 13, The ridge work is performed by attaching the ridge device 2 to the self-propelled vehicle body 1.
[0019]
When sowing or seedlings are transplanted to the ridges treated as described above, the seeds or seedlings are pierced through the hardened ridge surface layer at the time of sowing or seedling transplantation, and are sown or seeded on the unhardened lower soil layer. Will be the method of porting. If sowing or seedlings are transplanted by this method, the ridges whose surface layer has been treated as described above can maintain a state where the above effects can be sufficiently exerted even after sowing or transplanting of seedlings.
[0020]
Next, examples shown in FIGS. 3 and 4 will be described. In this example, instead of treating the ridge surface layer portion in the form of the clay, the paper covering the ridge is treated in a state of being stuck to and adhered to the soil of the ridge surface layer portion by a sprayed liquid. Paper roll supporting means for supporting the rolled paper roll 23, guide means 25 for guiding the paper 26 drawn from the paper roll 23 to the upper surface of the ridge, and paper 26 coated with the ridge to be in close contact with the ridge surface layer. This is a ridge surface layer treatment apparatus having a configuration in which a liquid spraying unit for spraying a liquid such as water is provided.
[0021]
Explaining the specific configuration of the example of the figure, in the example of the figure, a ridge device 2 is connected to the rear portion of the self-propelled vehicle body 1 so as to be able to move up and down freely, and left and right ridges are formed on both sides of a rear portion of the tilling device 10 of the ridge device 2. Plates 12 and 12 are arranged, and a paper mulling device 22 is arranged behind the left and right ridge forming plates 12 and 12. The paper mulch device 22 includes a support device 24 for a paper roll 23 attached to a frame portion of the tillage cover 11, a paper roll 23 wound around the support device 24, and a paper 26 drawn from the paper roll 23. A guide roller 25 for guiding and contacting the portion, left and right pressure reducing wheels 27, 27 for compressing the left and right ends of the paper 26 into grooves of the ridge, and left and right rotating disks 28, 28 for cutting the soil in the grooves and applying to the left and right ends of the paper 26. It is provided with a configuration. The liquid spraying means is attached to a liquid tank 19a provided at the rear part of the self-propelled vehicle body 1, a pump 19b for feeding liquid, a hose 20 extending from a discharge port of the pump 19b, and an end of the hose 20. The spray nozzles 21,... (Not shown) are provided to spray the liquid over the entire left and right widths of the ridge. The spray nozzles 21 are arranged so as to spray the liquid on the ridge after being covered with the paper 26 or on the ridge before being covered with the paper 26. In the illustrated example, the left and right rotating disks 28 are arranged behind the disks 28.
[0022]
When the self-propelled vehicle body 1 is run while rotating the rotating parts of the fuselage, the structure constructed as described above is plowed by the tillage device 10 of the ridger 2, and wide ridges are formed by the left and right ridge forming plates 12, 12. It is formed. Next, the paper 26 is pulled out from the paper roll 23, and the drawn paper 26 is guided by a guide roller 25 so as to contact the surface layer of the ridge. It is held down in the groove. Next, the soil cut by the left and right rotating disks 28, 28 is applied to the left and right ends of the paper 26, and the paper 26 covers the entire width of the ridges and grooves. Next, the liquid is sprayed from the spray nozzles 21,... Over the entire width of the covered paper 26, and the paper 26 adheres closely to the ridges and the groove surface.
[0023]
Therefore, in the above-described configuration, by covering the ridges with paper that can be corroded by soil, it is possible to favorably suppress the growth of weeds from the ridges, and it is also possible to eliminate the removal work after the end of cultivation. Agricultural labor can be reduced, and environmental problems can be avoided even when incinerated and disposed of because it is made of paper.
[0024]
Further, conventionally, the top surface of the ridge is covered with a multi-sheet made of paper. However, since the paper is thick and heavy, handling is difficult and costly, and there is a disadvantage that thin paper is easily broken. . However, by processing as described above, the paper covering the ridges is in a state of being stuck to the soil on the ridge surface layer portion by the sprayed liquid, so that weeds grow from the ridges than before. It can be suppressed well, and it is difficult for the paper to break due to the wind entering between the paper and the ridge surface.Thus, conventionally, it is possible to use a thinner paper than a paper mulch simply covered on the ridge, Material costs can be reduced.
[0025]
When a water-soluble glue is mixed with the liquid, the adhesiveness of the paper to the soil is enhanced, and the paper can be securely adhered to the surface layer of the ridge. When sowing or transplanting seedlings into a ridge covered with paper, use a method in which the paper is broken through at the time of sowing or transplanting seedlings, and the seeding or seedling is transplanted into the soil below the paper. become. If the seeding or the seedling is transplanted by this method, the ridge treated as described above can maintain a state where the above effects can be sufficiently exerted even after the seeding or the transplanting of the seedling.
