Description

Detailed Description of the Invention (Objective of the Invention) (Industrial Application Field) The present invention relates to a transplanting machine, for example, for transplanting lettuce or other transplants to a transplanting part on a ridge covered with a mulch film. Concerning what goes on.

(Prior Art) Conventionally, this type of transplanter has, for example, a main body frame having running wheels on the left and right sides, a guide disk having a drop opening at one place fixedly covered on the upper part, and a turntable mounted on the guide disk. A number of seedling storage bodies each having the guide disk as a bottom plate are disposed at predetermined intervals on the outer periphery of the turntable, and a vertical movable groove is provided in the main body frame to be operated by the movement of the transplanter. There is a structure in which a transplanter is provided which can be moved up and down to receive the transplanter dropped from the drop opening and transplant it to the transplanting part of the ridge.

(Problems to be Solved by the Invention) The transplanter having the above configuration is preferable in that it can transplant the transplanter to the transplanting part of the ridge at predetermined intervals. If a situation occurs in which the device is inserted into the transplantation part of the ridge and the transplanter hits the end of the ridge and cannot advance further, the vertical movement mechanism will not operate, so the transplant The device cannot be pulled upwards from the transplant site, and therefore the transplanter cannot be moved to the next transplant site,
There are problems such as not being able to change direction. Furthermore, since the transplanter is moved up and down as the transplanter is moved, the transplanter is moved up and down in conjunction with the movement of the ridge other than the transplanted portion, which poses a safety problem. In addition, a complicated control means is required to control the rotation of the turntable so that the transplanter inside the seedling container can be accurately dropped from the droplet of the guide disk, and the transplanter is not placed above the droplet of the guide disk. Whenever a seedling storage body containing a seedling container is moved, a complicated control means is required to move the transplanter upwardly to a position directly below the drop opening, and the imitation thereof is also complicated.

Therefore, the present invention was made in view of these problems, and allows the transplanter to be easily pulled up and stopped from the transplanted part of the enemy as needed, and to accurately position the turntable at a predetermined position. It is an object of the present invention to provide a transplanter that is simple in construction and safe in handling, which allows the turntable to stop, and allows the transplanter to be accurately received in the transplanter by ensuring that the transplanter faces directly below the seedling storage body of the turntable. This is the purpose.

[Structure of the invention]

(Means for Solving the Problems) The transplanting machine of the present invention includes a movable main body frame, and a support frame provided on the upper part of the main body frame so as to be rotatable in the horizontal direction. A turntable is provided with a large number of seedling storage bodies at a distance, and a brake ring is fixed to the lower circumferential side of the turntable, and the rotation of the turntable pull is braked through the brake ring provided on the upper side of one side of the support frame. A brake 4-mechanism is provided on the front side of the support frame so as to be rotatable in the vertical direction, and a front end portion of the support frame is provided with a brake mechanism for transferring the transplanter received from the seedling storage body of the turntable to the transplanting part of the ridge. and a link mechanism that rotates the turntable intermittently in conjunction with the vertical movement, and a drive shaft that is operatively connected to the link mechanism and includes a power switching mechanism that switches the power transmitted to the link mechanism. An operating lever that remotely switches the power switching mechanism and the brake mechanism of the drive shaft; and the operating lever switches the power switching mechanism and the brake set, and moves the transplanter upward from the transplanted portion of the ridge. It is equipped with a spring that pulls it up.

(Function) In the transplanter of the present invention, when the transplanter is brought close to the transplantation part of the ridge for transplantation or the like by the downward rotational movement of the 1-meter link, or when the transplanter is stuck in the transplantation part of the ridge, When the operating lever is switched remotely, the power switching mechanism of the drive shaft is switched, power transmission to the link mechanism is canceled, the operation of the link mechanism is stopped, and the brake mechanism is switched to brake the turntable. The braking action on the ring is released. Also,
As described above, power transmission to the link mechanism is released,
In addition, the braking action on the turntable is released, and the transplanter is automatically pulled up and stopped from the transplantation part of the ridge via the link mechanism by the lifting action of the spring, so that the transplanter can be moved safely. Can be done.

Next, when the operating lever is further switched, power is transmitted to the drive shaft by the switching operation of the power switching mechanism, and the brake ring of the turntable is braked again by the switching operation of the brake mechanism. When the link mechanism is rotated upward, the transplanter is rotated toward one of the seedling storage bodies of the turntable, and the turntable is rotated at a predetermined angle by the link mechanism in the middle of the upper back. However, at this time, the turn chisel is braked by a brake mechanism via a brake ring, so that one seedling container holding the transplanter is accurately moved and stopped in the transplanter supply section. Further, the transplant W dropped from the seedling storage body of the transplanter supply section is automatically received by the link mechanism into the transplanter that has been raised in advance to the transplanter supply section.

Furthermore, when the turntable is rotated by a predetermined angle as described above due to the upward rotation of the link mechanism, the empty seedling container into which the transplanter was dropped and supplied in the previous step is removed from the transplanter supply section. moved and prepared for the reception of the transplant]11']'.

Next, when the link mechanism is rotated downward, the transplanter that has received the transplanter is lowered, and the transplanter in this transplanter is transplanted vertically to the transplantation part of the ridge. By roughly rotating the link mechanism, the transplanter is pulled up from the transplantation portion of the ridge, and is operated again as described above to receive the transplanter into the transplanter. In this way, as the main body frame is advanced along the ridges, the transplanter, which is lowered at predetermined intervals, is sequentially rotated intermittently. The transplant device can be sequentially accommodated from the ridge, and the transplant devices can be sequentially transplanted at predetermined intervals to the transplant portion of the ridge.
