Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a riding type rice transplanter in which a seedling planting device is connected to the rear of a four-wheeled traveling vehicle body so as to be able to be raised and lowered,
By rationally configuring and arranging the traveling vehicle body and seedling planting equipment, we can minimize the trampling of the fields by the wheels, and we can even out the tracks of the wheels and reduce the flow of mud caused by the wheels. The purpose is to minimize the amount of water and stabilize the planting posture and position.

Embodiments of the present invention will be described below based on the drawings.

The riding type rice transplanter of the present invention has a pair of left and right front wheels (1).

+1) and rear wheels +2+, +21,
A seedling planting device (6 rows) is installed at the rear of a passenger vehicle body (4) in which a seat (3) is installed between the left and right rear wheels (21, +21) via an upper link (5) and a lower link (6). 7)
The seedling planting device (7) is configured to be able to move outward by a hydraulically driven lift arm (8) at the rear of the heavy body, and the seedling platform (9) on which the mat seedlings (5) are placed is reciprocated with a constant stroke. While moving horizontally, 6 sets of seedling planting machines are placed near the lower end of the seedling stand (9). (II) The structure is such that flO+... is activated to divide the seedling blocks for one planting from the mat-like seedlings and plant them on the leveled river surface. .

Front wheel (1), fll and rear wheel f2 of the traveling vehicle body (4)
) and +21 are respectively arranged on the treads that cross the planned planting area of the two central rows, and when the vehicle is running straight, the passage marks of the front wheels 11) and +11 are the rear wheels +2), respectively.
The outer structure 111 of the rear wheel (2) is configured to be wider than each width of the front wheel T1) so as to be included in the path of +2+.

Then, the soil leveling float (11) installed on the seedling planting device (7)
) group, each of the two wheels in the center is the rear wheel (21# (located at the rear of 21, and the wheel passage track is in the center)
(11>, 1ll).

In addition, a V-shaped preliminary soil leveling tool (1) is installed between the rear wheel (2) and the leveling float (river), and it is used to remove large soil ridges that have been pushed away by the wheels, and to remove dirt from the plowing plate with the wheel lugs. The raised earth clods are broken down by the preliminary leveling tool t12) K, l:
After approximately leveling and backfilling, the land is leveled flat using a leveling float (the bottom of the river).

Note that the symbols in the diagram (1.0 and 1.0 are spare seedling storage frames 04 arranged on both sides of the front of the vehicle) are line markers for forming the driving reference line for the next trip on the field surface.

As explained above in the embodiments, the riding type rice transplanter according to the present invention has the front wheel tread and the rear wheel tread of the traveling vehicle body substantially the same.
At the same time, the tracks of each rear wheel are made to overlap, so the trampling of the river surface by the wheels is kept to a minimum. Now I can figure it out.

When the picks and wheels move in a paddy field, mud flows outward laterally due to the soil removal action of the profit margin, and mud flows that flow into the passage grooves are observed, especially when the mud flows into the wheel passage grooves. Mud flow occurs not only near the surface layer where seedlings are planted, but also in the deep layer near the tiller, so in soft paddy fields, a fairly wide area around the track where the wheels pass will be in a state of mud flow. Therefore, in order to stabilize the planting posture, it is important to reduce the occurrence of such mudflow to as small an area as possible. This is extremely effective in stabilizing the planting posture.

Furthermore, in the present invention, when leveling the wheel tracks, instead of simply scraping, M 4tl! Rather than leveling by pressing down to maintain a constant pressure with the wide bottom surface of the soil leveling float equipped with the i device, it was possible to not only level the surface layer but also prevent mudflow from relatively deep layers. Also, the number of cases where the planting rows become slanted or bent due to movement of the surface mud within the shadow of mud flow remaining in the deep layer of 1M after planting has been reduced by one point.
