[Conventional technology and its problems]

BACKGROUND ART Conventionally, as described in Japanese Patent Laid-Open No. 63-42612, there is a seedling transplanter provided with a working seedling receiver that is operated by switching a seedling take-out port between a closed state and an open state.

However, since the conventional one has a structure in which the actuation seedling receiver is opened and closed by a drive system different from the seedling transplanter, the seedling transplanter of the seedling transplanter actually takes out the seedlings through the seedling take-out port. It is extremely difficult to properly match the timing with the opening / closing timing of the activated seedling receiver, and due to the operation error and the dimensional error of the members, the timing is deviated and proper seedling transplantation cannot be performed.

[Means for Solving the Problems] The present invention, in order to solve the problems of the above-mentioned prior art, the seedling transplant 72 of the seedling transplanting device 37 in the seedling cradle 83 that supports the bottom surface of the seedlings sent out. Forming a seedling take-out port 84 that can pass from above to below and receiving the bottom of the seedling at the seedling take-out port 84 and maintaining the same or substantially the same height as the upper face of the seedling receiving base 83, the seedling take-out port closing In the seedling transplanter provided with the operating seedling receiver 93 which is operated to switch between the state and the open state in which the seedlings taken out during the seedling transplanting operation of the seedling transplanter 72 can be moved downward, the seedling transplanting device 37 has the seedling taking-out port 84. In addition to switching the operating seedling receiver 93 from the closed state to the open state by the operation of passing through, when the leaf stem portion of the seedling to be taken out passes through the seedling take-out port 84, the seedling transplanting device 37 opens the operating seedling receiver 93. Seedling transplantation characterized by having a switching mechanism for switching from the closed state to the closed state It is obtained by the.

[Effects of the Invention]

In this invention, the seedling transplanting device 37 switches the operating seedling receiver 93 from the closed state to the open state by the operation of passing through the seedling take-out port 84, and when the leaf stems of the seedling to be taken out pass the seedling take-out port 84, Since the transplanting device 37 is provided with a switching mechanism for switching the operating seedling receiver 93 from the open state to the closed state, when the seedling transplanting body 72 of the seedling transplanting device 37 is not taking out seedlings, the seedling take-out port 84 is operated by the operating seedling receiving port 84. Since it is closed by body 93,
The unexpected situation in which the seedlings delivered to the seedling take-out port 84 collapse and fall from the seedling take-out port is prevented. The seedling outlet 84 is open until it passes,
The working seedling receiver 93 can prevent the seedling from being damaged.
However, the seedling receiving device 93 is activated by the seedling removal operation of the seedling transplanting device 37.
Since the seedling transplanter 72 of the seedling transplanting device 37 passes through the seedling take-out port 84 to take out the seedlings, it is possible to accurately match the opening and closing timing of the operating seedling receiver 93. It can be easily done, and it is possible to prevent the situation where the opening and closing timing of the operating seedling receiver is deviated due to the transmission error and the dimensional error of the member, which makes it impossible to properly transplant the seedling, as in the prior art,
The seedlings can be transplanted satisfactorily in a state where the seedlings are reliably taken out and damage to the seedlings is prevented.

The central part is cut away from the rear to the front so that the plan view is concave, and the seedlings are transplanted to this part. The grounding body 11 is attached to the grounding body mounting plate 100 pivotally attached to the bracket 8 by a pin 99 to an arm 98 which can be pivotally adjusted up and down by a pin. 1
1 is attached so that it can tilt left and right and front and back in a resilient state. As a flexible mechanism of the embodiment, the three separate
The pin 101 of the book, the spring 102, and the spring receiving body 103 attached in the retaining state are elastically stopped. And this grounding body 1
1 is provided so as to follow the surface of the ridge A. Further, the arm 104 integrated with the grounding body 11 and the hydraulic switching valve 105 of the hydraulic device 17 are interlockingly connected with each other by the rod 106, and when the height of the ridge A of the grounding body 11 becomes high, the vehicle body is levitated. Therefore, the valve 105 is switched so that the front wheel 14 and the tail wheel 12 are lowered, and conversely, when the height of the ridge A is low, the front wheel 14 and the tail wheel 12 are raised so as to lower the vehicle body. .

Reference numeral 106 denotes a hole excavating device, and 107 denotes a soil covering device. The hole excavating device is composed of a claw that moves up and down so as to make a hole in the upper surface of the ridge before the transplant body is about to transplant seedlings. Further, some soil cover devices press the ridges on the left and right sides of the transplanted seedling to bring the soil to the root portion of the transplanted seedling.

Reference numeral 108 denotes a control frame, the base portion of which is fixed to the transplantation transmission case 36 and is erected upright upward, and a control handle 110 and a control casing 110 equipped with various operation levers are fixed to the upper end side thereof.

A safety cover 118 is made of a transparent or translucent synthetic resin and fixed to the transplant transmission case 36 and the right frame 42 and covers the rear side and the upper side of the transplant device 37.
In the figure, reference numeral 119 is a lever for adjusting the reference setting position of the grounding body 11, which is used to adjust the rotation of the arm 98.

Explaining the operation of the above example, the engine 2 is started and the traveling clutch is set to "on" by the lever 111, and the lever 112
By switching the hydraulic valve with and projecting the piston 18a of the hydraulic device 17, the propulsion wheels 14, 14 and the tail wheels 12, 12 are lowered through the interlocking rod 23, the rods 32, 32, 35, 35, etc. Raise and operate the throttle to increase the rotation of the engine 2 and operate the transmission mechanism in the traveling mission case 1 with the centrifugal clutch to rotate the propulsion wheels 14 and 14 to steer and propel the transplanter and to drive the ridge A in the field. The left and right wheels 14, 14 and the tail wheels 12, 12 straddle each other to stop the airframe. Then, the lever 112 is operated to switch the hydraulic valve to raise the wheels 14, 14, 12, 12 and lower the machine body. Then, the back side of the grounding body 11 is the ridge A.
The grounding body 11 is pushed up by bringing it into contact with the upper surface of the ridge A so as to hold it. Then, when the contact pressure becomes appropriate, the arm 104 of the grounding body mounting plate 100 pushes the rod 106 to switch the hydraulic pressure switching valve 105 to the neutral position to stop the projection of the piston 18a, and to raise the wheels 14, 14, 12, 12. Stop.

Then, the back surface of the grounding body 11 and the upper surface of the ridge A are brought into proper contact with each other. This is because the grounding body 11 is attached to the mounting plate 100 via a flexible mechanism.
That is, the grounding body 11 is attached by the three pins 101 and the springs 102 so that it can be tilted in any direction such as left and right and front and back, so that the ridge A is removed except for a part on the front end side and the rear end side. I will deal with you.

In this state, each seedling B is independent in a state in which the pots a are filled with soil and sowed by the paper seedling raising device C as shown in FIG. After mounting the pot-shaped vegetable seedlings raised in the above, the rear end surface of the one row of rear end seedlings can be received by the pot receiving rod 85, and then the engine 2 is rotated at high speed by the throttle operation. The centrifugal clutch is set to "ON" and the aircraft is propelled by the propulsion wheels 14 and 14, and the transplant clutch is set to "ON" with the lever 113 to operate the transplant device 37 and the seedling table 38.

Then, the seedling mounting table 38 is reciprocally operated to the left and right to feed the pot-shaped seedling B to the seedling take-out port 84, and at the same time, the first seedling of the transplanting device 37.
Rotation The rotation case 45 rotates backward and the second rotation case 46 rotates forward at twice the rotation speed, and the transmission gears in these rotation cases raise and lower the implant 47 while maintaining a fixed posture. Pot-shaped vegetable seedlings B that are fed to the seedling separation port 84 between the fixed and movable transplants 72a and 72b.
The seedlings are transplanted into the holes of the ridges that have been ground by the lower grounding body 11 and excavated by the hole excavator 106 as they are. In this case, the seedling extruder 74a rapidly moves downward when the implant 72 plunges into the dug hole, and substantially coincides when the movable implant 72a opens, and acts to drop the seedling into the hole. . Therefore, the bottom surface of the pot seedling B is accurately pressed into the soil and is not damaged, and is accurately released into the hole. After that, the soil is covered by the soil cover device 107 to the plant side of the seedling B to which the soil has been transplanted, and the soil is transplanted reliably. Even when the ridges are covered with the mulch film, the ridges are transplanted in substantially the same state, and the soil under the film is brought through the film.

The state of taking out the seedling B from the above-mentioned seedling take-out port 84 is such that the bottom surface of the pot-like seedling B is received and the seedling B is held upright in a stable state with the operating seedling receiver 93 closing the mouth 84. In this state, the seedling transplanter 72 intervenes from above to forcibly push down the operating seedling receiver 93 to open and take it out. At this time, since the actuating seedling receiver 93 is rapidly opened by the tumbler mechanism, the seedling leaf is not damaged even if it is a vegetable seedling that spreads to the outer periphery,
In addition, the seedling take-out port 84 can be widened so that the seedling take-out port can be reliably taken out, and as soon as the transplant body 72 passes, the return rod 95 attached to the transplant tool 47 hits the projection rod 96 to receive the operating seedling. The body 93 is restored so that the seedling take-out port 84 is closed. Then, when the seedling length is large and the seedling outlet 84 needs to be opened for a long time when dividing the seedlings due to the variety of seedlings and the growth state, the return rod 95 is moved upward and fixed, and vice versa. If the plant height is small, it is better to move it downward and fix it.

In this way, the seedling B is transplanted to the upper surface of the ridge A,
If the height of the ridge A is high or low during this transplanting operation, the ground pressure of the grounding body 11 naturally fluctuates, and the front side of the grounding body 11 rotates up and down. By this operation, the hydraulic switching valve 105 is switched, the propulsion wheels 14, 14 and the tail wheels 12, 12 are moved up and down, and are held at the height of the machine body with reference to the upper surface of the ridge A.

 Therefore, the seedling transplant depth is kept constant.

In addition, when the field is in the mountains and the ridge A is formed along the inclined surface, the aircraft tilts to the left and right, which prevents proper transplantation. The lever 117 on the interlocking rod 23 is rotated so that one of the wires 115 is pulled by actuating 114 and the other one is loosened. Then, the cam intervened in the hole 27 of the metal 22
26 comes into contact with the inner peripheral surface of the hole 27 and is rotated, and the interlocking rod 23 side is pivoted.
Rotate around 24. Therefore, the left and right wheels 14,14, tail wheel 1
The height of 2,12 fluctuates, and the aircraft can be held in a substantially horizontal state. For such operations, metal
Since the shaft 22 is guided to the frame 3 side so as not to wobble, the piston 18a of the hydraulic device can be easily operated without being unnecessarily twisted.
