TECHNICAL FIELD OF THE INVENTION
The present invention relates to a configuration of a transplant nail in a vegetable transplant apparatus.
[0002]
[Prior art]
Conventionally, a configuration in which a vegetable seedling is housed in a beak-shaped claw and thrust into the lower soil and then the beak is opened and transplanted has been known. I did not find it.
[0003]
[Problems to be solved by the invention]
Conventionally, when a beak is opened in the soil, the spread of the beak has the disadvantage that the soil is piled up and back, and the transplant hole becomes large, so that the topsoil disappears at the root of the transplanted seedlings and the growth is lost. There was a delay disadvantage.
[0004]
[Means for Solving the Problems]
The present invention has taken the following technical measures in order to solve the above-mentioned problems. That is, the beak-transplanting claw 15 having an open upper side and a beak-like lower side is raised and lowered by an appropriate driving device, and the beak-transplanted claw 15 is closed and held when it is on the upper position. The vegetable seedlings A that have arrived are introduced into the beak transplanting claws 15, and the beak transplanting nails are transplanted by opening the beak transplanting claws 15 when moving downward to enter the soil. Vegetable transplanting nails characterized in that a part of the lower side of the rear transplanting nails 15b on the back side of the opening operation of 15 was missing (c) to the extent that the potted soiled block of vegetable seedlings A did not fall off. .

【Example】
An example of the present invention will be described in detail with reference to the drawings.
Reference numeral 1 denotes a traveling vehicle body. Chain cases 3 and 3 are provided on both left and right sides of a transmission case 2 and traveling wheels 4 and 4 are axially mounted. An engine 5 is provided at a front portion of the transmission case 2 and a rear side. The implant transmission case 6 is attached to the housing. Reference numeral 7 denotes a V-belt transmission case.
[0006]
Numeral 8 is a seedling supply device, which is equipped with a flexible seedling growing pot frame, and is configured to intermittently move horizontally and horizontally and intermittently rotate in the vertical direction, and has a seedling pushing device described later. . Reference numeral 9 denotes a rear frame, on both left and right sides of which a space is formed in an intermediate portion, so that the seedling transplanting apparatus can intervene in the left and right spaces (a). Further, the seedling raising pot frame itself is configured to be moved left and right and left and right in the left and right space.
Reference numeral 10 denotes a steering handle. Numeral 11 denotes a transplantation device. A front and rear intermediate portion of an operation frame 12 extending in the front and rear direction is attached to a crank mechanism 13, and a beak is provided at a front end side of the operation frame 12 linked to a swing arm 14 at a rear end portion. A front beak transplant nail 15a of the transplant nail 15 is attached, and an upper side of the rear transplant nail 15b is pivotally connected to a rear side of the front transplant nail 15a by a pin 16. That is, the rear beak implant claw 15b is rotatably provided rearward on the pin 16 as a fulcrum, and the two beak implant claws 15a and 15b are configured so that the beak is always kept closed by the spring 17.
[0007]
A cam 19 is fixed to the crankshaft 18 of the crank mechanism 13. The cam 19 is moved forward and backward by the cam 19 to project the shaft 20 to the rear side of the operation frame 12, and the shaft 20 and the rear beak transplanting claw 15b A pin 22 is inserted into a long hole (b) formed in the projection 21 provided at the rear, and the rear beak implant claw 15b is in the beak closing direction at the upper position, and the shaft 20 is retracted by the cam 19 at the lower end. And is configured to be pivotally moved rearward on the beak opening side. Reference numeral 23 denotes a retracting-side urging spring of the shaft 20.
[0008]
The lower part of the rear side of the posterior beak transplanting nail 15b is missing (c) to the extent that the potted soiled block of the seedling A does not fall off. The seedling supply device 8 loads the vegetable seedlings A with soil grown in the bendable pot-shaped seedling raising frame 24 for each seedling raising frame, and intermittently moves the seedling raising frame 24 to the pitch of the pot horizontally and horizontally. A seedling frame transfer mechanism 25 that is sequentially and intermittently transferred to one pot pitch in the vertical direction, and a pot that moves forward and backward by a crank mechanism 26 and stops at a predetermined position, and that grows inside from the bottom of the pot of the transplanting frame. And a seedling extruding rod 27 for extruding soiled seedlings A one by one.
[0009]
The operation of the above example will be described. When each part is driven while propelling the traveling vehicle body 1 with the left and right wheels 4 and 4 straddling the ridge of the field, the operation frame 12 swings up and down by rotation of the crank 13 and is attached to the operation frame 12. The beak implant claw 15 is moved up and down while drawing an elliptical implant locus (d) in side view.
[0010]
On the other hand, the pot-shaped seedling raising frame 24 set in the seedling supply device 8 is intermittently transferred right and left and back and forth while filling the seedlings A that have been raised. The seedlings A are extruded one by one from each pot of the pot-shaped seedling raising frame 24, and the extruded seedlings A are dropped into the upwardly moving beak transplanting claws 15. At the time of this fall, since the root side of the indigenous soil is heavy, it is dropped and supplied in a normal posture in which the root side is located in the lower part of the beak.
[0011]
Then, the seedlings A housed in the beak transplanting claws 15 move down by the operation of the crank mechanism 13, and the beak transplanting claws 15 rush into the soil on the upper surface of the ridge. At this time, the shaft 20 corresponds to the step portion of the cam 19 and is pushed by the pressing force of the spring 23, so that the shaft 20 is suddenly retracted. Therefore, the rear transplanting claw 15b of the beak transplanting claw 15 pivots rearward and upward around the pin 16 to open the beak, and releases the seedling A stored therein into the hole dug by the beak and transplants it.
[0012]
When the beak transplanting claw 15 is pushed into the soil and the rear beak transplanting claw 15b pivots rearward to open the beak, the rear lower beak transplanting claw 15b has a configuration in which the lower rear end is missing. The soil on the back side soil surface of the transplanting nail 15 is not discharged, and the front beak transplanting nail 15a does not become a hole larger than the hole where the soil surface is excavated due to the function of dragging the soil by the fuselage propulsion. Since the seedlings A are discharged and transplanted, the survival of the seedlings after transplantation is improved, and the seedlings are not clogged in the beak when the seedlings A are discharged, and the release is not hindered. Can be expected.
[0013]
It is possible to improve the survival of more seedlings A set of front transplantation pawl 15a made smaller wellbore is set as the angle θ leaning forward inclination of 5 beak transplantation pawl 15 in the embodiment.
Another example shown in FIGS. 6 to 8 is a seedling B in which a transplanter for vegetable seedlings or the like grows in a pot shape continuously at a predetermined pitch left and right and back and forth at the top of a self-propelled body 30 equipped with an engine. A seedling mounting table 31 is provided for transferring vertically in the lateral end while moving in the horizontal direction, and a fixed seedling receiving table 32 is provided on the lower surface of the seedling mounting table 31 on the side of the feeding portion of the potted seedling B. A seedling dividing opening (e) is formed at the center on the left and right sides of the seedling receiving table, and the seedlings B sequentially fed out into the seedling dividing opening (e) are attached to the transplanting tool 33 attached to the transplant operating means. A transplant locus (f) to be divided and held by the claw 34 and transplanted to the lower ridge surface is drawn, and each pot portion B1 of the potted seedling B fed out to the seedling receiving table 32 is received and prevented from falling down. Receiving rod 35 is provided, and leaves B of the pot seedling B are provided on the left and right sides of the receiving rod 35. The brush 36 for preventing the 2 from protruding to the rear side is planted. As a result, the leaves B2 of the seedling B are not damaged by the transplanting claws 34 at the time of transplanting and dividing, and reliable seedling division holding can be expected.
[0014]
In addition, the code | symbol in a figure, 37 is a running wheel, 38 is a rolling back wheel, 39 is a pressure-reducing wheel, 40 is a leveling board, and 41 is a steering handle.
In another embodiment shown in FIGS . 9 to 11 , a description will be given of a seedling replenishing device for a potted seedling in a riding type transplanter. A link mechanism 52 is provided at a rear portion of the riding type tractor 50 via an elevating mechanism 51, and a transplanting device 53 is mounted on the link mechanism 52. The transplanting device 53 includes a seedling table 54 that moves laterally left and right, and a transplanting tool 56 that splits and holds the seedlings from a seedling division 55 at the rear end central portion of the seedling table 54 and transplants the seedlings to the lower ridge. Consists of The seedling mounting table 54 has a configuration in which seedling feeding belts 57 are wound around the left and right sides of the bottom surface. When the seedling mounting table 54 moves to the left and right ends, the seedling mounting 54 is driven intermittently to produce seedlings. ing. The seedling dividing port 55 is bored in a seedling receiving table 58 fixed to the rear end bottom surface of the seedling mounting table 54 and attached to the machine body.
[0015]
A drawer-type seedling placement / supply plate 59 is provided between the left and right seedling feeding belts 57, 57 which can be inserted and removed from the front side, and a mat of seedling pots is placed on the seedling placement / supply plate 59. By sliding the plate 59, the seedling can be easily supplied from the seat 60 side of the tractor 50. In the transmission mechanism diagram of the vegetable transplanter shown in FIG . 12 and FIG. 13 of another example, a clutch mechanism for stopping at a fixed position is configured in the transplantation part transmission part in a separate system from the traveling transmission part in order to change between transplanted strains. In a configuration in which the fixed position stopping clutch is turned on and off at regular intervals by a timer to change the stock, the fixed position stopping clutch can be turned on and off as much as possible. In order to prevent the occurrence of the time lag, the clutch form is formed into a spline engagement structure such that the engagement between the driving clutch pawl and the driven clutch pawl is caused by the engagement of the spline pawl having a small pitch. This will be described in detail with reference to the drawings. The drive unit drives the traveling unit-side transmission gear and the transplant unit-side transmission gear from the engine side, and drives the fixed unit stop clutch 61 from the transplant unit transmission gear-side. The right and left moving mechanism 64 of the seedling mounting table 63 and the transplanting device 65 are driven from the shaft 62. The fixed position stop clutch 61 is fixed to the drive shaft 62 and the clutch cam 68 having a female spline which moves with the pin 66 against the spring 67 due to the rotational force due to the pushing of the clutch pin 66. And a clutch body 69 having a male spline shaft. The clutch pin 66 is operated in and out by a solenoid SL which is instructed to be turned on and off by a CPU of the control unit. The on / off control interval is configured to be adjustable by a manual dial 70.
[0016]
The minimum interval at which the clutch is turned “on” and “disengaged” by the dial 70 is set to be wider than the interval of the engagement chance of the spline type clutch. In other words, the clutch has a greater width than the maximum time required for the end face of the width t1 of the protrusion that forms the fitting groove of the female spline section to engage with the end face of the width t2 of the fitting strip of the male spline section. The off-time is extended. By doing so, the set pause time is accurately obtained, and the interval between transplanted strains exactly matches the set interval. More specifically, while the end surface at t1 and the end surface at t2 are in abutment before the clutch is “engaged”, the clutch is not actually “engaged” even if the clutch is “engaged” by the command signal. It becomes idle, and this is repeated when the clutch is turned on and off, so that the desired stock cannot be obtained. As a means for preventing this, if an idle time is set longer than this play time, such an unexpected situation does not occur, and an accurate stock interval can be obtained.
[0017]
In the embodiment, the pause time is set by the dial 70, but may be set by any other means.
[0018]
Operation and Effect of the Invention
According to the present invention, when the beak-transplanting nail is opened in the soil, the rear surface of the lower part of the rear nail of the beak-transplanting nail is missing, so that the rear surface of the beak-transplanting nail is less likely to push the surface of the field to the rear side. Since the topsoil on the side is pressed against the potted seedlings and the seedlings are transplanted, the survival after transplantation becomes good.
