Japanese Unexamined Patent Publication No. 2016-136899

The support frame of Patent Document 1 has a square cross-sectional shape. Since the support frame is arranged along the left-right direction and has a long overall length, there is room for improvement in terms of weight reduction.
An object of the present invention is to reduce the weight of the support frame when the support frame is provided in the seedling planting device.

The seedling planting apparatus of the present invention
Support frames arranged along the left-right direction,
A planting arm is rotatably supported at the rear portion, and a planting transmission case connected to the rear side portion of the support frame and extended to the rear side is provided.
In a side view, the support frame is vertically oriented over an upper portion along the horizontal direction, a lower portion along the horizontal direction, a rear end portion of the upper portion, and a rear end portion of the lower side portion. It has the rear side portion provided along the line, and the front side portion provided linearly over the front end portion of the upper portion and the front end portion of the lower side portion.
In the side view, the cross-sectional shape of the support frame is set so that the front-rear length of the lower portion and the front-rear length of the upper portion are different .
In the side view, the cross-sectional shape of the support frame is such that the front-rear length of the lower side is the front-rear length of the upper part so that the front side surface portion of the front side portion is in a forward tilted state so as to be positioned forward toward the upper side. It is set shorter than that, and the cross-sectional shape of the support frame is a uniform cross-sectional shape over the entire length of the support frame .

In Patent Document 1, the front-rear length of the upper portion of the support frame and the front-rear length of the lower portion of the support frame are the same length.
On the other hand, according to the present invention, since the front-rear length of the lower portion of the support frame and the front-rear length of the upper portion of the support frame are set to be different, the lower portion or the upper portion of the support frame is shortened. It can be made into a product, and the weight of the support frame can be reduced.

In the seedling planting device, various members of the seedling planting device are rarely connected to the lower portion of the support frame.
According to the present invention, the upper portion of the support frame maintains the function of supporting various members as the support frame, and even if the front-rear length of the lower portion of the support frame is shortened, the function as the support frame is maintained. Is not impaired.

In a passenger-type rice transplanter, when the seedling planting device is supported by the rear part of the machine body, the mud splashed to the rear side by the rear wheel of the machine body may hit the front side surface portion of the front side part of the support frame.
According to the present invention, since the front side surface portion of the front side portion of the support frame is in a forward tilted state, even if the mud splashed to the rear side by the rear wheels of the machine hits the front side surface portion of the front side portion of the support frame, Mud easily falls from the front side surface portion of the front side portion of the support frame to the lower side, and does not easily adhere to the front side surface portion of the front side portion of the support frame.

In the present invention
The lower part of the seedling stand is supported by the planting transmission case,
It is preferable that the seedling pedestal frame is connected to the front side surface portion and extends upward, and the upper portion of the seedling pedestal is supported by the upper portion of the seedling pedestal frame.

When the planting depth lever 29 is operated from the state shown in FIG. 5 to change the position of the axis P3 (rear part of the float 12) with respect to the seedling planting device 6 to the lower side, the seedling planting device 6 is activated. The set height from the surface of the rice field to be maintained increases, and the set depth of seedlings becomes shallower.

As described above, when the planting depth lever 29 is operated to change the set depth of the seedlings, the connecting member 41 swings around the axis P5 in conjunction with the planting depth lever 29.
When the position of the shaft core P3 (rear part of the float 12) with respect to the seedling planting device 6 is changed to the upper side, the position of the inner 43a of the wire 43 (the end portion 41a of the connecting member 41) is also changed to the upper side accordingly. NS. When the position of the shaft core P3 (rear part of the float 12) with respect to the seedling planting device 6 is changed to the lower side, the position of the inner 43a of the wire 43 (the end portion 41a of the connecting member 41) is also changed to the lower side accordingly. Be changed.
