Since the second drive shaft portion 70b of the second stop rotor 27b is supported only by a pair of left and right chain cases 73 and 73, the left and right ones may be used to reinforce the chain cases 73 and 73. The reinforcing member 74 which mediates a pair of chain cases 73 and 73 is provided.

In addition, the second stop rotor 27b uses the pair of link members formed of the first link member 76 and the second link member 77 whose upper end is supported by the girder member 66 to form the spring 78. Are hanging through.

The pair of link members may include a first link member 76 having one end fixedly supported to the girder member 66 and a second link member having one end connected to the other end of the first link member 76 with a rotating material ( 77, and the spring 78 is connected between the other end of the second link member 77 and the mounting piece 74a that is supported by the reinforcing member 74 by the rotating material.

When the second stop rotor 27b is moved upward, the first stop rotor 27a is also moved upward at the same time through the second drive shaft portion 70b and the first drive shaft portion 70a.

In this embodiment, the first stop rotor 27a and the second stop rotor 27b, which are 40 mm above the field surface in the standard position, may be rotated up to 15 mm higher than the standard position by the rotation of the rotor lifting motor 63. Moreover, it is set as the setting which can be made up to 15 mm lower than a standard position by the reverse rotation of the rotor lifting motor 63. As shown in FIG.

As shown in FIG. 4, since the said 1st stop rotor 27a and the 2nd stop rotor 27b are made to be able to move up and down with the rotor lifting motor 63, since it stops, Even when the first stop rotor 27a and the second stop rotor 27b are stopped, the first stop rotor 27a and the second stop rotor 27b are quickly deformed at the time of turning of the body. It can be set as the structure which raises automatically by the rotor lifting motor 63 in conjunction with the rise of the transplant part 4.

Spring 78 or the like with respect to the parent implant 4 so that the second stationary rotor 27b can escape from the lower links 41 and 41 of the elevating link device 3 when the parent implant 4 is raised. Since it is supported through, the 1st stop rotor 27a is supported by the mother implant part 4 with flexibility.

Moreover, in the structure which adjusts the 1st stop rotor 27a and the 2nd stop rotor 27b to a set height by the rotor height adjustment dial provided on the meter panel which is not shown in the vicinity of the seat 31. You may also

When the rotor height is set manually, the first stop rotor 27a and the first stop rotor 27a and the first stop rotor 27b are moved to the stowed position while the first stop rotor 27a and the second stop rotor 27b are moved to the stowed positions. Although the 2nd stop rotor 27b may not be used, if it is set as the structure which automatically adjusts the 1st stop rotor 27a and the 2nd stop rotor 27b to a setting height, inconvenience can be prevented.

As a result, the first stop rotor 27a and the second stop rotor 27b are lowered at the time of the idle swing, and only the turning mark can be stopped. In this case, the control device (not shown) is turned on by the elevating link sensor (not shown) of the upper link 40 and the lower link 41 of the mother implant 4 and the rotor interlocking grain switch (not shown). 101 performs drive control of the rotor lifting motor 63. In the case of such a structure, since the rotor lifting motor 63 can be automatically operated, operability improves.

As described above, the first stop rotor 27a and the second stop rotor 27b are lifted by operating the motor for lifting and lowering the rotor 63. (Not shown) when the non-dung clutch (not shown) for transmitting the engine power is "broken" by the operation of the non-dung clutch lever (not shown), the rotor lifting motor 63 operates to automatically operate the first. The stop rotor 27a and the second stop rotor 27b are lowered to perform the stop operation. Therefore, the non-turtle clutch lever sensor 19a (FIG. 4) which detects the connection and disconnection of a non-turtle clutch lever is provided.

Therefore, in the immersion and its vicinity, when the non-dung clutch is "cut off" by operating the non-dung clutch lever for transplantation coordination, the non-dung clutch lever sensor 19a detects "cutting off" of the non-dung clutch lever and controls it. By the apparatus 101 (FIG. 4), the 1st stop rotor 27a and the 2nd stop rotor 27b can be automatically lowered to perform a stop operation.

This makes it possible to reliably stop the immersion or the vicinity of the immersion which tends to be rough in the field.

In the direct wave machine of the present embodiment, the contestant sensor 114 (FIG. 5) which can detect the rigidity of a field is arrange | positioned between the 2nd stationary rotor 27b arrange | positioned in the center of a base, and the center float 55. As shown in FIG.

Instead of mounting the contestant sensor 114 directly to the center float 55 as disclosed in Patent Document 2, it is disposed just before the center float 55 and behind the second stop rotor 27b. The detection value of the field rigidity by the contest sensor 114 is not influenced by the center float 55 which is a float in contact with the field with a relatively large ground area, so that the field rigidity can be accurately detected. Therefore, since the height position with respect to the field of the mother transplant apparatus 52 can be precisely controlled, the control degree of the hair transplantation depth by a mother transplant port (not shown) can be improved.

In addition, the contest sensor 114 is composed of a soil detection tool 114a supported in a shape that plays an intermediate role between the left and right pair of chain cases 73 and the contest detection tool 114b that enters the soil and detects the soil. The tool 114a and the contest detection tool 114b are made into the structure which intrudes into ground or soil. The soil detection tool 114a and the contest detection tool 114b are the first arm part 114aa and the 2nd arm part 114ba, the said 1st arm part 114aa, and the 2nd of the back-down of a vertical rotation material, respectively. 1st roller part 114ab and the 2nd roller part 114bb of the rotating material attached to the rear end of the arm part 114ba of this are provided. In addition, the center part of the 2nd roller part 114bb of the contest detection tool 114b becomes sharp in order to make it easy to penetrate into soil. In addition, the relative relationship between the angle formed between the first arm 114aa of the soil detection tool 114a and the second arm 114ba of the contest detection tool 114b is detected by potentiometer to detect the soil hardness. Doing.

Since the contest sensor 114 is arrange | positioned between the left and right pair of chain cases 73 for driving the 2nd stop rotor 27b, the contest sensor 114 can be arrange | positioned near soil, and the contested degree of soil The detection degree of is good. Moreover, it is set as the structure which changes the inclination angle of the cover plate 59 (FIG. 1, FIG. 2) automatically based on the soil content of the contest sensor 114, and controls the extent of cover. Moreover, since the arm length of the 1st arm part 114aa of the soil detection tool 114a is comprised longer than the arm length of the 2nd arm part 114ba of the contest detection tool 114b, the detection of the contested degree of soil is stabilized. Can be performed with high accuracy.

When the seed tank 85 of the linear wave device 82 long in the width direction of the base is opened, the lower portion of the seed tank 85 is a plurality of funnel-shaped first small pieces in the width direction of the base. It consists of the small tank which consists of the tank 85a and the 2nd small tank 85b. FIG. 6 is a plan view (FIG. 6A) and a side cross-sectional view of two small tank portions including an adjacently arranged first small tank 85a and a second small tank 85b on one end side of the seed tank 85. (FIG. 6B) is shown. As shown in FIG. 6, the capacity | capacitance of the 1st small tank 85a of the shortest side is made smaller than the capacity of the 2nd small tank 85b adjacent to it. And the residual amount sensor 115 of a fertilizer is arrange | positioned in the 1st small tank 85a with a smaller capacity.

Thus, by placing the weight detection type residual amount sensor 115 in the 1st small tank 85a of the minimum capacity among the several small tanks arranged in parallel in the seed tank 85 of the waveguide device 82, If there is no seed in the 1st small tank 85a of the minimum capacity with which fertilizer is discharged early, if residual quantity sensor 115 can confirm, it can be made the sign which replenishes fertilizer to each small tank in seed tank 85. have.

In this way, since it is not necessary to arrange the remaining amount sensor 115 in all the small tanks, there is an effect of reducing the labor and cost of arranging the plurality of remaining amount sensors 115.

By the way, when operating the seeding raising / lowering lever 83 provided in the vicinity of the seat 31, it is output by the input from the seeding raising / lowering lever position sensor 83a to the electrohydraulic valve which is not shown through the control apparatus 101, The lifting linkage device 3 is rotated by the operation of the lifting hydraulic cylinder 46 to lift the straight wave device 82 relative to the main frame 15. Moreover, when the direct wave device 82 is lowered by the operation of the seed raising / lowering lever 83, the float which consists of the center float 55 and the side float 56 provided in the lower part of the said wave directing device 82 is grounded to the field surface.

Moreover, it is the structure which can operate the seed feeding part 87 of the direct wave apparatus 82 mentioned later by operating the feeding clutch which is not shown by operation of the seeding raising / lowering lever 83. As shown in FIG.

And the seeding depth can be stabilized by adjusting the air volume from the blower 99 according to the sensitivity of the float sensor. In other words, in the case of blowing sowing, the effect of blocking the water is greater than that of the mud in the field. Therefore, when the mud and the water-rich field are soft, the blowing force is increased, and the seed can invade into the soil, and the seeding depth is properly adjusted. can do. If the mud and the field with little water are hard, the seed can invade in the soil while preventing the seed from scattering even if the blowing force is weakened.

As described in FIGS. 1 to 3 and the like, the seed from the seed tank 85 of the wave directing device 82 is center-float via the seed dispensing part 87, the fertilizing hose 62, and the like by blowing the blower 99. It is supplied to the groove | channel formed in the field by the seeding implementor 64 attached to the 55 and the side float 56. As shown in FIG.

And as shown to the top view (FIG. 7A) and the side view (FIG. 7B) of the installation part of the center float 55 and the side float 56 of FIG. 7, the cover plate 59 is a seeding implement ( Since it is attached to the center float 55 and the side float 56 in the rear part of 64, the waterproof plate 47 is attached to the outside of the cover soil plate 59 and the seeding implement 64, so Water does not enter the grooves, and the transplantation effect of the seed can be expected.

When the handle 34 is turned to the left side, it is necessary to drive the rotor lifting motor 63 to automatically control the first stop rotor 27a and the second stop rotor 27b to lift a little from the field. have. This is because the structure of the engine 20 is not transmitted to the first stop rotor 27a and the second stop rotor 27b when the handle 34 is turned to the left, so that the first stop rotor If the 27a and the second stop rotor 27b are turned to the field while turning, the first stop rotor 27a and the second stop rotor 27b will only press the mud in the field without rotating. In order to prevent this inconvenience, it is important to slightly float the first stop rotor 27a and the second stop rotor 27b from the field during the turning of the body.

In addition, as shown in FIG. 1, the rotor cover 37 is provided above the 1st stop rotor 27a and the 2nd stop rotor 27b, and the center float 55 and the side float ( 56) It is set as the structure which mud does not hang on.

In addition, the first stop rotor 27a and the second stop rotor 27a and the second stop rotor 27b are positioned in front of the rotor cover 37 by connecting the sub-float 120 to the first stop rotor 27a and the second. The buoyant force can be applied to the stop rotor 27b of the controller, and the hydraulic negative charges of the first stop rotor 27a and the second stop rotor 27b can be reduced, and the accuracy of the control sensitivity can be improved.

As shown in FIG. 5, when the contaminant sensor 116 including the potentiometer 116a and the ground plate 116b is provided on the front side of the second stop rotor 27b, the contaminant sensor 116 stops at the second stop. Detecting a contaminant in front of the rotor 27b can automatically decelerate the advancing of the gas, and stabilizes the mother implantation performance when the mother implanter 52 is provided.

Moreover, when the contaminant sensor 116 detects a contaminant, by shifting the control sensitivity of the lifting hydraulic cylinder 46 of the parent implanter 52 to the desensitization side, even if there is a detection of some contaminants, the mother implanter 52 ) Does not vibrate in the vertical direction.

Moreover, as shown in the side view of FIG. 8A and the top view of FIG. 8B, the flap-shaped contaminant sensor 117 which can detect the contaminants, such as straw garbage, of the 1st stop rotor 27a and the 2nd stop rotor 27b is shown. If it is installed in the front, the blade-like contaminant sensor 117 automatically places the first stop rotor 27a and the second stop rotor 27b on the field when straw dust or the like is detected, and then straw or the like. Can be laid under the first stop rotor 27a and the second stop rotor 27b.

In addition, as shown in FIG. 5, if the topsoil height sensor 119 of a field is provided other than the contaminant sensor 116 provided in the front side of the 2nd stationary rotor 27b, if there are many unevenness | corrugation in a field, or there are many contaminants The first stop rotor 27a and the second stop rotor 27b are automatically laid down so as to ground the field, the field is equalized, and the contaminants are placed in the first stop rotor 27a and the second stop rotor. Can be laid under (27b).
