Description

[Detailed Description of the Invention] The present invention relates to an apron support device in a rice transplanter, which is fixed to the machine body at the lower end of the seedling stand and supports the lower end surface of the planted seedlings.

Conventionally, the fuselage attachment portion of the apron has been constructed by integrally and continuously molding a rectangular tube with a hollow cross-section. Therefore, when attaching the apron to the aircraft, or when attaching a sub-float or wheel mark erasing member to the apron, it is necessary to make holes in the apron each time, and in addition, a nut is inserted in the middle of the hollow part of the long apron. It is difficult to assemble fixing members such as the above, making the installation work extremely troublesome.

Therefore, in the present invention, a groove is formed in the attachment part of the apron over the entire length in the longitudinal direction, and the hollow part has a flange and is opened by the groove. It is an object of the present invention to provide an apron support device for a seedling stand, which is configured so that a clamp member can be inserted from the side along the apron, and which eliminates the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the rice transplanter 1 has paddy wheels 2.
It has a body 3 that is swingably supported by. The fuselage 3 is composed of an engine 5, a transmission 6, etc., and has a planting rod 7 at the rear thereof which is rotatably driven via the transmission 6.
A float 9 is swingably suspended below the float 9, and a handle 10 extends further rearward. A seedling stand 12 is slidably supported on the upper part of the handle 10 via a slide block 11, and the seedling stand 12 can place planted seedlings on it, and can also be moved horizontally by a cross-feeding device. It is driven back and forth in the direction. Further, an apron 13 is provided at the lower end of the seedling table 12 and extends over the entire length of its reciprocating stroke, and the apron 13 protrudes forward as shown in FIGS. 2 and 3. It consists of a seedling support part 15 made of a tongue-shaped part and a mounting part 16 made of an opening enclosure shape, and is integrally formed by drawing aluminum or the like. Seedling support part 1
5 is a notch 15a at a predetermined location corresponding to the number of planted rows.
is provided, and the planting rod 7 is connected from the notch 15a.
A split groove 16a is formed in the mounting portion 16 along its entire length in the longitudinal direction.
As a result, the hollow portion 16b is shaped to open through a narrow passage formed by the flanges 16c, 16c projecting from both sides.

Then, as shown in FIG. 4, the apron 13
The shaft 17a is attached to the apron mounting frame 3a of the aircraft body 3.
The hollow part 16b of the mounting part 16 is laterally inserted into the eccentric circular cam 17 which is fitted and supported, and the nut 19 is screwed into the screw formed on the shaft 17a at a predetermined position, thereby connecting the cam 17 and the mounting frame. It is fixed by sandwiching the flange 16c between it and 3a. Further, the shaft 17a of the cam 17 is formed with a square shaft portion, and a lever 20 is non-rotatably fitted onto the square shaft portion, and a nut 21 is further screwed into the square shaft portion. As a result, with nuts 19 and 21 loosened, lever 2
0, the eccentric circular cam 17 whose outer periphery is fitted in the hollow portion 16b almost closely is rotated together, the apron 13 is moved and adjusted in the direction of the arrow, and the nut 19 is tightened at the desired position. , 21, it is fixed. Therefore, the amount of feed in the vertical direction of the planted seedlings can be adjusted, and the amount of each seedling can be arbitrarily adjusted steplessly.

Further, as shown in FIGS. 5 and 6, a clamp member 22 having a head 22a larger than the split groove 16a is attached to the hollow part 16 of the attachment part 16 of the apron 13.
b from the lateral direction along the split groove 16a, and fix the bracket 23 at a predetermined location by tightening the nut 24 to the threaded shaft 22b of the clamp member 22, and accessories such as the sub-float 25 can be attached. .

As explained above, according to the present invention, since the split groove 16a is provided in the attachment portion 16 of the apron 13 over the entire length in the longitudinal direction, the eccentric circular cam 17 etc. The apron 13 can be easily attached to the fuselage 3 by inserting the clamp member, and the eccentric circular cam 17 or the like is used as the clamp member so that its outer peripheral surface can be fitted into the hollow portion 16b almost closely. By using the adjustment cam, it is easy to adjust the vertical movement of the apron 13, and the apron 13 can be installed and adjusted with one member, so the number of parts is reduced and the appearance can be neatly organized. can. Furthermore, using the split groove 16a having the flange 16c,
Similarly, by inserting the clamp member 22 from the side, the sub-float 25, the wheel mark erasing member,
Accessories such as markers can be easily attached to any left or right position.
