[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter having a seedling table and a planting claw for continuously carrying out seedling planting operations.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Application Laid-Open No. Sho 59-210821 is disclosed.
As shown in (1), there has been a technique in which a seedling table is reciprocated to slide left and right through seedling table rails arranged in a plurality of upper and lower stages, and a seedling mat on the seedling table is sent in a seedling removal direction by a vertical feed belt. .

[0003]

In the prior art, the lower seedling rail is provided near the seedling outlet at the lower end side of the seedling platform inclined, so that the vertical belt feeding end is located away from the seedling outlet, It is necessary to slide the seedling mat from the end of the vertical belt feeding to the seedling take-out port, so that the longitudinal feeding amount of the seedling mat tends to be uncertain, the number of seedlings taken out per plant becomes uneven, and the lack of plants occurs. There was a problem such as doing.

[0004]

In order to solve the problems] However, the present invention is, up and down
Tsu by the multiple arranged seedling stand rail for the right and left reciprocating sliding to stage
Converting mechanism mounting the loading table seedling in rice transplanters the seedling mat providing a vertical feed belt to send the seedling direction on the mounting stand seedlings, upward to place the lower seedling stand rails than seedling mat conveying portion of the vertical feed belt, The feed end side of the vertical feed belt is placed as close as possible to the seedling removal section of the seedling platform, and the seedling sliding distance from the vertical belt feed end to the seedling removal section of the seedling platform is determined. The length of the seedlings can be remarkably shortened compared to the conventional method, the vertical feeding of the seedlings can be performed more reliably than in the conventional method, and the number of seedlings taken out per plant can be made uniform, and the prevention of lack of plants can be easily achieved.

In the rice transplanter provided in 6), the seedlings of the vertical feed belt (37)
Mat (40) Seedling rail in the lower section above the transport section
(18) is arranged, and the feed end side of the longitudinal feed belt (37)
Is placed as close as possible to the seedling removal part of the seedling mounting table (16).
The vertical feeding belt (37) and the seedling table (16)
Seedling sliding distance to the seedling removal area is significantly
Shorten the seedlings more securely than before,
The aim is to equalize the number of seedlings that can be taken out per plant and to prevent stock-out.
It is configured so that:

A seedling extracting plate (42) forming a seedling extracting port (41) is provided at a seedling extracting portion at the lower end of the seedling mounting table (16), and is slidable in the inclination direction of the seedling mounting table (16). The arm portion (44) of the seedling take-out plate (42) is attached to the planting case (20) via the pins (43) and (43), and the planting case (20) is attached via the seedling taking-out amount adjusting shaft (45). ) Is provided with an arm (46) for adjusting the amount of seedlings that can be swung, and the arm (46) is attached to the seedling removal plate (42) by a rod (47).
The feed end side of the vertical feeding belt (37) is connected to the seedling mounting table (16) by a seedling extraction plate (42).
And a seedling mat (40) between a seedling outlet (41) for taking out seedlings of one strain with a planting claw (17) and a feed end of the vertical feeding belt (37). Is shortened as much as possible, and the seedling take-out plate (42) is moved to the seedling mounting table (1) by operating the seedling vertical picking amount adjusting arm (46).
6) Independently displaced up and down to change the amount of planting nails (17) vertically picked up.

Further, as shown in FIGS. 6 and 7, three vertical feeding belts (37) are provided for one row of seedling mats (40).
And longitudinally feeding left middle right arm (4) to rollers (38) of each belt (37) via a one-way clutch (48).
9) A vertical feed left rod (52) and a left lever (53) that are connected to (50) and (51) and abut on the left arm (49) of each strip to swing, and a middle arm of each strip. (5
0) A vertically feeding rod (54) that swings by contacting with.

The vertical cam arm (59) of the planting case (20) is brought into contact with the middle right lever (53) (55) (57) in order from the left or right side, and the seedling mounting table (16) is slid to the left. When the seedling table (16) is slid to the right, the left middle right lever (53) (5
5) The vertically moving cam arm (59), which is always rotating, is brought into contact with (57), and the seedling mat (40) is divided into three sections in the left-right direction. The three vertical feeding belts (37)... Are operated with a time difference as much as they are to be taken, and the seedling mat (40) is divided into three stages each time a seedling having a width of approximately one-third is taken out by the planting claw (17). 6), the seam (40a) of the seedling between the upper and lower seedling mats (40) (40) shown in FIG.
a) When the seedlings of the portion are taken out with the planting nails (17), the amount of the seedlings taken out is stabilized and the occurrence of the lack of stock is prevented.
