[Problem that the idea aims to solve]

The above-mentioned conventional partial tillage transplanting machine connects the transplanting device to the rear part of the tilling device. The plowing device and the transplanting device descend at the same time, and when they touch down, the length of the aircraft becomes significantly longer. As the weight of the rear part becomes extremely large, it is necessary to lift the tilling device and transplanting device when turning the aircraft. The power consumption is extremely large to raise the seedlings, and when transplanting seedlings, the transplanting equipment needs to be The seedlings are transplanted onto hard, untilled rice fields, resulting in abnormal transplants. The planting claws of the planting body have drawbacks such as premature wear and breakage, and in addition, there is a large bump at the front. It is necessary to attach a run weight, which causes problems such as an increase in the weight of the machine.

It is tied. At the front ends of these front stays 19, 19, there is a groove shaft made of a hexagonal shaft. 20 rotatably supported, and is formed by the planting body 14 of the groove making shaft 20. In the part corresponding to the virtual extension line of the planting row, a disc-shaped groove member 21 is bored in the center. Sleeves 23, 23a are fitted into the hexagonal holes and attached to both sides of each groove forming body 21. , 24, and suspended vertically adjustable. The outer periphery of the groove forming body 21 A number of serrated groove cutting blades 21a have a tooth oscillation, and the width of the tooth oscillation is When forming the groove 21b, it should come out at an angle α of about 90 degrees with the rice field when viewed from the side, and , is an arc-shaped curved blade with a large radius R, and the tip has a rounded edge. Since it is configured with a small radius r, the straw waste 56 etc. scattered on the rice field 55 is removed by the groove cutting blade 21. It wrapped around a and was not lifted up, but was thrown forward and sideways and was eliminated. Ru.

[0008] And, on both sides of each groove-forming body 21..., a diameter smaller than the outer diameter of the groove-forming body 21 is provided. The rollers 22, 22 are fitted into the sleeves 23, 23a, 24 so as to freely rotate. The row The rollers 22 and 22 are solid or hollow to prevent mud, straw 56, etc. from entering inside. Consists of the body. Furthermore, a sleeve 23 and a roller 22 attached to the end of the groove forming shaft 20 are provided. Fix the washer 25 with a bolt 26 to prevent it from coming off, and fit it into the sleeves 23 and 24. The lateral movement of the roller 22 is determined by a C-shaped retaining ring 27, and the roller 22 is While in contact with the ground, it freely rotates independently of the groove-forming body 21 and compresses the scattered straw waste 56, etc. While covering, both sides of the groove 21b formed by the groove cutting blade 21a are leveled to almost the same height. Suppress. In addition, in order to prevent straw waste 56 etc. from getting wrapped around the outer peripheral surface of the roller 22, a scraper is provided. The tip of the support plate 28a hanging from the tee 28 is made of a rubber plate, and one side is made of a rubber plate. A scraper 28b extending in a cantilever shape toward the groove-forming body 21 is attached, and the scraper 28b is The lower end edge of the scraper 28b is in sliding contact with the roller 22, and the side edge of the scraper 28b is in sliding contact with the groove forming body 22. 1. Slidingly contact or bring it close to 1. In addition, bolt 29 is attached to the front of the planted transmission case 12, 12. Adjust the hole on the side of the installed bracket 31 and the long hole of the groove-forming bracket 32 with the adjusting bolt. 33, and tighten the adjustment bolt 33 to an arbitrary position to adjust the front stay 1. The height of the front portions 9 and 19 can be adjusted up and down.

[0009] As shown in FIG. 8, the transmission is transmitted from the mission case 5 to the rear groove case 34. The power of the drive shaft 35 is provided by a coupling 36, a sprocket 37, a chain 38, The input shaft 41 of the reduction gear 40 is driven via the input sprocket 39, and the switching gear 42 is driven. When the gear 43a is engaged with the gear 43a, the forward rotation is decelerated, and the gear 44b of the reverse rotation shaft 44 and the gear 44b are constantly engaged. The output shaft 43, the universal joint 45, and the transmission are decelerated in reverse through the meshing gears 44a. The signal is transmitted from the moving shaft 46 to the hollow shaft 47 that is telescopically fitted. 60 is up with the gear lever The switching gear 42 is operated to change the speed. 61 is a lever panel that positions the gear shift lever 60. I'll try it. 62 is a rear step.

0010 Further, as shown in FIG. 9, the power transmitted to the hollow shaft 47 is transferred to the groove forming case 34. The power transmitted to the input shaft 48 inside is changed direction by a pair of bevel gears 49, and The recording groove shaft 20 is driven. 51 is a bearing support that holds the hollow shaft 47; 52 is a bearing support that holds the hollow shaft 47; It's a bearing.

[0011] In the above configuration, when the transplanter runs while driving each part, the groove forming body 2 1 rotates the part corresponding to the planting position and splashes straw waste 56 etc. to the front and side. While doing so, the groove 21b is formed. At the same time, the roller 22 freely rotates independently of the groove forming body 21. Press down on the straw shavings 56 etc. that were blown away, and press both sides of the groove 21b while pressing the convex part. Suppress evenly to almost the same height. The planting body 14 is horizontally moved by the planting claw 13 at the tip of the planting body 14. The groove-making body scrapes off the mat seedlings one by one on the seedling platform 15, which reciprocates left and right in the direction. The extrusion tool 13a enters the groove 21b formed by the groove 21 from above and near the lower descending end thereof. is extruded and planted at approximately the same depth from the field surface which has been pressed and leveled by the rollers 22. . At that time, the groove 21b of the groove cutting blade 21a has a width that is wider than the outer width of the planting claw 13. Because it is formed narrowly, when the planting claw 13 invades and plants seedlings, the outside of the planting claw 13 The edges slightly scrape off the sides of the groove 21b, but the soil inside the groove 21b has turned into mud. The groove 21b penetrates smoothly and has rough surfaces on both sides of the planted seedling, especially the root stock. When the planting claw 13 comes into contact with the side surface of the groove 21b or the striped groove formed inside the groove 21b, In both cases, the extrusion tool 13a pushes the root stock of the seedling into the narrow groove 21b below the tip of the planting claw 13. Since it is forcibly pushed in, both sides of the root stock will be pinched by both sides of the groove 21b. To allow the seedlings to be separated easily and to maintain the seedlings in an orderly upright posture.

0012 In addition, the no-tillage transplanter of this invention completes one cycle of planting and rotates around the headland. At this time, a groove-making device consisting of a groove-making shaft 20 and a plurality of groove-making bodies 21 attached to the groove-making shaft 20 is used. By simply attaching it to the front of the transplant device 9, there is no change in the overall length of the aircraft, and there is no increase in weight. Since it is not very large, the machine can be operated with almost the same operability and circular radius as a riding rice transplanter. I can. In addition, since the planting body forcibly transplants the seedlings into the groove 21b, premature wear of the planting claws may occur. There is no breakage etc.

[Effect of the idea]

As explained above, the present invention has a plurality of planting bodies placed at intervals in the lateral direction behind the vehicle. The transplanting device is constructed by setting up a seedling stand at the part facing the transplanted bodies. In a transplanter equipped with the transplant device so as to be able to move up and down, the A groove-making shaft in the direction is rotatably supported, and a groove-making shaft is made on the outer periphery at a portion corresponding to the planting body. Each groove-forming body with a groove blade is attached, and a diameter smaller than the outer diameter of the groove-forming body is attached on both sides of the groove-forming body. Since the rollers are arranged so that they can rotate freely, the unevenness on both sides of the groove formed by the groove-forming body can be eliminated. The rollers will be used to flatten and level the soil, and since the rollers can freely rotate, the mud and soil will be flattened. There is no adhesion or rotation of straw waste, so even in no-tillage fields where the field is uneven, It is possible to reliably level the seedlings and plant them in an orderly manner without causing tumbled or floating seedlings. Ru. In addition, even if straw waste is scattered in the field, the groove-making body will splash it and the rollers will remove it. Because it is compressed and leveled, straw waste does not get wrapped around the groove-making body, similar to a riding rice transplanter. Not only can you perform stable planting work, but there is no wear or breakage of the planting nails. .
