Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for planting seedlings on a traveling vehicle body that has been equipped with a traveling transmission mechanism 1-*! This invention relates to a riding rice transplanter in which a kwIi is interlocked and connected so that it can be raised and lowered.

For rice planting 1m2, it is desirable to travel at a slower speed on the headland than when driving for planting work, and when driving on the road, it is rare to travel in relation to 11m1. There is τ. Therefore, in the past, the speed t of FjT- was obtained by operating the transmission #t according to the driving condition of the Krcs planting work and the driving condition of the seedling seeding device. In addition to manual operation, you also have to perform gear shifting operations, which reduces operability.

The present invention is limited to the above-mentioned points, and the J!
1! The purpose is to be able to perform planting work traveling, turning, and driving on the road well at 4 degrees without any problems.〇Next, the aspect of the misfired It4 Teikyu will be explained based on an illustrative diagram. .

A pair of left and right wheels in the front and rear + 11 pairs, lll
.

(2) is mounted on the shaft and the engine is mounted on the front part of the running vehicle body which is equipped with a control unit (ml), and the rear part is driven to raise and lower the moetsu shri@fil via the 4-link mechanism (4). It can be freely linked and connected to form a riding rice transplanter.

To drive the wheels ill, (ll and the seedling planting device (6), a split pulley (6) mounted on the engine output shaft (6) is used.
7) and the human pulley i that has not arrived at the mission input shaft 481
91, and fixes the movable piece a'4 of the tension pulley (10 acting on the belt 4, which is configured to apply one tension force to the belt 4, and the side boot 7). There is a belt-type non-vegetable cruiser barrel (lit mechanism) that allows you to operate the hot plate speed change by moving near and far to the piece 01.
A drive arm 11+1 is pivotally connected to the engine control, and the drive arm 11+1 contacts the stage 4 and prevents the loe moving piece 4 from shifting toward the low speed side due to the driving force Vζ of the bell seat 4.
The drive arm and the link (41) that powers the four-speed link mechanism (4) are protruded from the Fyr foot phase, and the next lever Oη
are interlocked and connected via a push/pull rod (111!!-),
Seedling planting device t61 k descending ground 4 to the next planting agitation position 2, close to the mouth f1 piece (l ft fixed piece) ^ suitable - gear change, from the 70 position prisoner, for example, about 603 The same amount of elevation on the headland, etc. of 1 m (2 on Bl and the lever 1
17) and the rod are connected in a nearly straight line, and the movable piece O is shifted from the fixed piece 4 to the most interlayered, and the speed is changed to a low-speed trout.
Furthermore, from tW4 to about 80 countries, for example, 1 well was added.
VC41111112 is used so that when driving on the road or other non-working situations, the movable piece is moved closer to the fixed piece and all speeds are changed carefully.

To give an example of the relationship between the position of the seedlings with respect to the aircraft and the traveling speed, as shown in Figures I & 5 by Gukufu, at the planting work position ll1 (5), the position of the seedlings is 11 (5).
m, the same amount tik [181 is approximately α4FI ~ α5 g
tn/w, and about α7t at the non-working position (0;
The speed of n/sO is greatly improved.

The interlocking connection between the lever η and the movable piece of the split pulley (7) is not limited to the one consisting of an arm and a rod as described above, but various modifications are possible, for example, with a wire width. These are collectively called mechanically interlocked MAT4.

In addition, the present invention is not limited to the above-mentioned belt-type non-IR transmission mechanism, but also includes a fluid pressure type transmission mechanism using a hydraulic motor of a modified type, etc., in order to continuously adjust the running speed. (Also, those f speed mechanism 114 and seedling planting device)
To connect them, a device is attached to detect the position of the seedling planting device 11tI) with respect to the machine body, and the above three positions (6), (6), ( 0) Set the lever tIIIEllF for the transmission mechanism +141 so that the desired high speed or low speed state can be returned to each position.
Even if 411A is operated visually by an I motor or the like, it is not acceptable.
In this case, seedlings are planted on the transmission mechanism curvature k11! [
16+1 A special imitation of high JK in the planting working position and the greatly elevated non-working position, and interlocking and interlocking in a low speed state at the turning position between the inner position. shall be.

In other words, the driving conditions for planting work, poor circulation on headlands, and non-working driving conditions such as driving on the road. linked,
Since the transmission mechanism 04 is automatically set to low speed and heavy speed, there is no need to change the speed when changing the driving state as mentioned above, and it is not only possible to drive for planting work and turn around on the headland, which can be done during work driving. Even when escaping from the exit (2) and moving on to road driving, the speed desired by the F9r can be easily obtained, and there is no need for any operational problems simply by raising and lowering the original seedling planting device (6). It has become possible to run smoothly with M, turn around, and drive on the road without any discomfort.
