Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simultaneous scraping transplanting machine which performs seeding planting work simultaneously with scratching work. 2. Description of the Related Art Conventionally, a simultaneous transplanting machine which submerges a plowed field to plant seedlings at the same time as a substituting operation is a multi-row planting type rice transplanter. There has been proposed a device in which a substitute device is rotated in front of a planting claw and a float (sliding body) of the attaching device. The above-mentioned scraping device is, for example, in a planting device having six rows of planting claws on a drive shaft disposed laterally in front of the float, a rotor having a length spanning a plurality of planting claws. Are mounted close to each other by a predetermined number. [0003] However, in the scraping device having the above-mentioned conventional arrangement, the rotor is formed so as to straddle a plurality of planting claws, so that the length thereof is long. At the same time, since the rotors are provided close to each other, the pushing of the muddy water of the rotor accompanying the advancing of the fuselage at the time of the scraping is greatly generated, and the rotor is vigorously discharged to the side. As a result, this mud flow has the drawbacks of pushing down the seedlings that have just been planted, etc., and a long rotor leaves unscratched portions in the width direction on the ground where there are locally locally high protrusions, so planting failures occur. May occur. Further, since the ground resistance of each rotor is large, there is a problem that the consumed horsepower at the time of scratching becomes large.
In addition, long rotors are expensive to manufacture,
There are problems such as poor weight balance, easy breakage, and difficulty in replacing the rotor when the rotor is worn. [0004] In order to solve the above-mentioned conventional problems, the substitute simultaneous transplanting machine according to the present invention employs a hydraulic machine with a hydraulic machine.
Center float 71 connected to the automatic sensing control mechanism
Planting device in 6 and cash掻同time transplanter provided with a front of Dai掻device 5 of the float, the Dai掻device 5 the respective planting unit every 62 having a plurality of float and a plurality of planting section 62 including wherein the plurality of rotors 5a, 5b, 5c, together constituting mounted individually is separated between corresponding is allowed and adjacent rotor and 5d, the rotor 5d centrally located in cell
So that the center lines of the two floats coincide
And the width of the rotor 5d is adjusted to the center flow.
G is formed to be narrower than the width of the gate 71 . An embodiment of the present invention will be described below with reference to the drawings. A is a simultaneous scratching transplanter according to the present invention, which is provided with an engine E, a steering wheel 2, a steering wheel, a seat, and the like from the front on an upper part of a body 1 having a front wheel 1a and a rear wheel 1b. A hitch 30 is provided at the rear end of the elevating mechanism 3 composed of a top link, a lower link, etc., which is raised and lowered by a hydraulic cylinder mechanism (not shown) for automatic control of the planting depth. A central portion in the width direction of the planting device 6 provided with the scraping device 5 is supported by a rolling support shaft 31 (FIG. 3) so as to be able to freely tilt (roll) to the left and right via a metal portion. The planting device 6 has a planting machine frame 60 having a metal portion fitted to the rolling support shaft 31 and a seedling mounting table 61 and a planting claw (planting portion) for five-row planting. A transmission case 63 having a transmission case 63 is mounted.
A float type sliding body 7 is provided below the base 3 so as to be vertically movable via front and rear support links 7a and 7b (FIG. 2) by the following arrangement shown in FIG. That is, the sliding body 7 is a T-shaped 2 in which seedlings for one row are planted on both sides.
A strip sliding body 70 is disposed on the left and right sides, and a single strip sliding body (center float) 71 in which a single row of seedlings are planted at the rear side of the cutout is provided at an intermediate portion thereof. In this embodiment, the central slide 71 is connected to a hydraulic automatic sensing control mechanism (planting depth control mechanism) having the same structure as that of the conventional slide. Elevating mechanism 3
Is controlled up and down to keep the planting depth constant. As shown in FIG. 3, the planting device 6 has a center shaft of the single-row sliding body 71 and a planting claw 62 related to the center shaft of the single-sliding body 71 behind an extension of the center axis P of the rolling support shaft 31. The rotating shaft 63a pivotally supported in the transmission case 63 is separated from the rolling support shaft 31 by a predetermined distance H to the right by a drive shaft 8 which is driven from the body 1 side.
Thus, it is rotationally driven via bevel gears 8a and 8b provided in the bulging input portion case, so as to perform reciprocating left and right movements of the seedling mounting table 61, seedling planting operations of the planting claws 62, and the like. . At this time, the drive shaft 8 is rotated rightward to drive the planting device 6, so that the right sliding body 70 and the scraping device 5 are driven by the driving reaction force.
When the planting device 6 is lifted up on the right side around the rolling support shaft 31 by the contact pressure due to the unevenness of the field, etc., the planting device 6 is acted to cancel this, so that minute and frequent rolling of the planting device 6 is performed. Can be prevented. Further, as shown in FIG.
Are supporting arms 66, 66 extending on both sides of a rotor shaft 50 laterally provided at the planting width in front of the sliding body 7 via a rotating shaft 65 supported by a transmission case 63 (FIG. 1). The vertical adjustment mechanism 67 with a handle provided on the planting machine frame 60 side is connected to the support arm 66, and the scraping device 5 is operated by the operation of the vertical adjustment mechanism 67.
Is moved up and down so that the substitute depth can be adjusted. The above-mentioned rotor shaft 50 is driven by a drive shaft 9 which extends rearward from the body 1 side and "left-rotates" in a rotor case 51 which is mounted at an intermediate portion thereof.
The bevel gears 9a and 9b are driven in the scraping rotation direction. The drive shaft 9 is driven to the left by a predetermined distance “L” from the rolling support shaft 31 so that the left sliding body 70 and the scraping device 5 move the planting device by the ground reaction force. When the left side is lifted up around the center 31, fine and frequent rolling is suppressed as in the case of the drive shaft 8 side, so that a good planting operation with less vibration can be performed. The drive shafts 8 and 9 are separately driven by a transmission system shown in FIG. That is, engine E
The power transmitted from the power transmission is transmitted from the front transmission 1F, which supports the front shaft 1a and can be shifted, through the drive shaft 8 to the planting portion (planting claw) 62 of the planting device 6 and the seedling mounting table 61. , And the front transmission 1F is input to a rear transmission 1R for supporting and transmitting the rear wheel 1b via a traveling PTO shaft 1S. In the rear transmission 1R, the drive shaft 9 is branched and transmitted to drive the scraping device 5 in rotation. As described above, the two drive shafts 8 and 9 are arranged on both sides of the rolling support shaft 31 at intervals L and H, and rotate about the rolling shaft 31 in opposite directions. The driving reaction force can be canceled. The transmission case 63 of the planting device 6 transmitted from each of the drive shafts 8 and 9 and the heavy-weight case portion formed by internally mounting a bevel gear or the like at the input portion of the scraping device 5 are formed of the rolling support shaft 31. Since the planting device 6 is provided with a well-balanced left and right side, the planting device 6 can be rolled along the ground 3
1 can be smoothly tilted in the left-right direction. The drive shaft 8 can be extended through the upper part of the rotor interval of the scraping device 5 as shown in FIG. 1, and the transmission case 63 and the rotor case 51 are brought close to each other when viewed from the side. 63 can be of a simple configuration. Further, the rotor shaft 50 shown in FIG.
As shown in FIG. 5, basket-shaped rotors 5a, 5b, 5c, and 5d in which the outer peripheries of left and right frame plates 53 each having a shaft stopper hole 52 are connected by a scraper 55 at predetermined intervals are provided with different lengths. By the way, in order to be able to effectively scratch the front of each planting claw 62, they are individually pivotally mounted with a space therebetween. That is, the longest rotors 5a, 5a are disposed on both outer sides, the rotors 5b, 5c of the next length are disposed on the inner side via the mounting interval of the support arm 66 shown in FIG. (I.e., the center rotor) 5d is placed on the right side of the rotor case 51, and its center line is the center float 71 described above.
Are provided so as to match those of Since each of the five rotors 5a to 5d arranged in this way scratches the planting strip in front of each of the planting claws 62 arranged rearward, the seedlings can be satisfactorily planted. Can be. Further, since the rotors 5a to 5d which are shortened for each planting portion as described above can be provided in a state where the space between adjacent rotors is sufficiently widened, the rotor 5a to 5d can be provided from within this space at the time of scraping. The pre-driven muddy water flow generated by 5a to 5d can be easily released backward. The downsized rotor is advantageous in that the manufacturing cost can be reduced, and the attachment / detachment replacement work can be facilitated when the rotor is worn. On the other hand, the width of the center rotor 5d at the center is made narrower than the width of the center float 71, so that the center planting claw 62 at the center of the center rotor 5d can be scratched in front of it. This center float connected with the hydraulic automatic sensing control mechanism described above by leaving the untouched cultivated soil surface on both sides and sliding over the wide center float 71 on the rear side on the cultivated soil surface on both sides. 7
1 can respond accurately along the unevenness of the ground,
This makes it possible to perform accurate automatic planting depth control. [0017] The simultaneous transplanting machine configured as above is
In the cultivated and flooded field, the scraping device 5 is rotated by the drive shaft 9 while descending the planting device 6 and sliding the sliding body 7 on the surface of the ground, and furthermore, the planting unit 62 and the seedling mounting table 61 etc. Is actuated by the drive shaft 8, so that the seedlings can be planted simultaneously while performing scratching. At this time, the scraping device 5 pushes the muddy water on the ground surface in accordance with the rotation and progress of the scratching direction, and this muddy water is drained backward through the mounting interval formed between the rotors 5a to 5d. Therefore, the muddy water does not drain vigorously from both sides of the scraping device 5, and tilting of the planted seedlings can be prevented. Further, each rotor formed as a single unit with a short length for each planting claw 62 can accurately scrape the ground for each planting streak even if there are local irregularities on the ground surface. The seedlings can be satisfactorily planted. Further, the planting device 6 senses the planting depth control by the center float 71 and controls the planting up and down through the elevating mechanism 3, so that the seedlings can be satisfactorily planted at a constant depth. The rolling action centering on the rolling support shaft 31 can be smoothly performed without being affected by the driving reaction force of the drive shafts 8 and 9, and the planting claws located on both outer sides of the planting device 6. The planting operation can be favorably performed while preventing the deep or shallow planting of the seedlings by the plant 62. According to the present invention, the following effects can be obtained by the above configuration. When performing the substitute in front of the planting unit, the substitute unit scrapes the ground by dividing each of the rotors provided on the drive shaft for each planting unit, so that the seedling can be satisfactorily planted. . In addition, since the rotor formed short for each planting portion can be provided with a sufficient interval between adjacent rotors, the pre-pressed muddy water flow generated by the rotor at the time of scraping is drained and escaped from this interval. Therefore, tilting of the planted seedlings can be prevented. The rotor consists in a small type, it can facilitate maintenance work or the like of the fabrication and removable replacement. In addition, the center rotor
Mutual centerlines coincide before wide center float
So that the planting part located in the center with the rotor
Leave the uncultivated cultivated surface on both sides while scratching the front.
Then, straddle the center float on the cultivated soil
And the center float floats on the ground
It can respond accurately along irregularities and has hydraulic automatic
Because it is linked to the sensing control mechanism, the planting depth with high accuracy
Can be automatically controlled.
