Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter equipped with a guide for receiving and guiding block seedlings held by planting claws to the upper part of the bed.

In this type of planter, when the planting claw takes out the block seedling and moves it toward the planting mud surface while holding the upper part of the bed, the upper part of the bed collapses, causing disturbances in the planting posture of the seedlings, and floating seedlings. However, for the upper part of the bed, which has good shape retention properties such as clay, mud adheres to the guide due to the action on the upper part of the bed, and the adhering mud This has the disadvantage of causing the upper part of the floor to collapse unexpectedly, and depending on the properties of the upper part of the floor, the guide may become unnecessary.

However, in the past, the guides were configured to be attached and detached, and the guides had to be attached and detached each time the properties of the upper part of the floor changed, which was extremely troublesome, and there was a risk that the guides would be lost when not in use. There was also.

In view of the above points, it is an object of the present invention to make it possible to easily switch between using and non-using the guide according to the properties of the upper part of the floor without fear of losing it.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A float 1 is suspended and supported, and a pair of left and right wheels 2, 2
An engine 3 is mounted on the front part of a traveling machine which is mounted on an axis, and on the other hand, there is a seedling tray 4 at the rear for supplying seedlings while reciprocating in the transverse direction, and a predetermined amount of block seedlings is loaded from the seedling tray 4. A seedling planting device 5 is provided to take out the seedlings and plant them in the rice field.
Therefore, the walking rice transplanter is configured to continuously plant seedlings in the rice field as it travels.

The wheels 2, 2 each have a horizontal axis 1 attached to the transmission case 6.
It is mounted on a shaft on a transmission case 7 which is connected to the transmission case 7 so as to be able to swing freely around the machine, and the wheels 2.2 are raised and lowered relative to the machine body as the machine body sinks, thereby keeping the seedling planting device 5 at a substantially constant ground level. As clearly shown in FIG. 1, the wheels 2.2 are mounted on shafts on the inside of the respective transmission cases 7.7, and the float 1 and the transmission cases 7.7 are mounted on shafts. 7, and the transmission case 7.7 is configured so that, as much as possible, the transmission case 7.7 will not obstruct mud being washed away as the ground is leveled by the float 1 when the aircraft sinks significantly. .

The seedling tray 4 has its lower part supported by a sliding pedestal 8, and has a tank bottom that guides and supports the movement of the mat seedlings on the seedling tray 4 while receiving the downward facing side surface of the upper part of the bed. It is.

At a predetermined location in the longitudinal direction of the sliding pedestal 8, there is a seedling take-out port 10 through which the planting claws 9 of the seedling planting device 5 pass and take out one block of seedlings. A planting claw 9 is provided below each seedling take-out port 10.
Planting claw 9 along the rotation trajectory A of...
A guide 11 is provided to receive and guide the upper part of the bed of the block seedling taken out and held by the tank, and the tank bottom is provided to prevent the upper part of the bed of the block seedling from collapsing during planting.

As clearly shown in FIG. 2, the guide 11 is pivotally connected to the lower part of the sliding pedestal 8 so as to be able to swing freely around the horizontal axis 0, and the operating state along the rotation locus and the rotation are controlled. The bottom of the tank can be freely switched to a non-operating state in which it is spaced in front of the moving trajectory A.

The guide 11... Two cam surfaces a and b having different directions are formed at the swinging base end of each guide 11, and an elastic member is provided to selectively act on the cam surfaces a and b. A plate spring 12 is attached as an example of the machine, and the guide 11
The guide 1 is switched between the working state and the non-working state by the swinging of the guide 1 by the biasing force of the ammunition 12.
In order to maintain stability by pressure contact with 1, the cam surface a
, b and the leaf spring 12 form the posture maintaining mechanism F at the bottom of the tank.

The bullet is not limited to a leaf spring, and various other members such as a spring can be used.

Incidentally, the guide 11 may be connected to an operating tool provided near the operating handle 13 via a push-pull wire so that the attitude of the guide 11 can be easily changed by operation from the operating position.

In summary, the present invention has a seedling stand structure for a rice transplanter officially registered, in which the guide 11 is mounted at the bottom of the tank so as to be swingable back and forth around the horizontal axis Q, and the guide 11 is attached to the planting claw 9.
The operating state along the rotation trajectory A of the planting claw 9 and the rotation trajectory A of the planting claw 9
It is characterized in that it is provided with a posture maintenance mechanism F for switching to a non-working state in which it is spaced outward and maintaining the position in both the working and non-working states.

In other words, the guide 11 can be switched between an active state and a non-active state, and the position can be maintained in each state, so the switching operation for use or non-use depending on the properties of the upper part of the floor can be performed. , it has become possible to easily install and remove the device without having to install or remove it, and it has also become possible to reliably avoid loss when not in use.
