Abstract

PURPOSE:To facilitate rolling control, etc., of a seedling planter for a car body by linking a seedling planter machine body to a position above an interval part between a pair of left and right floats with a pair of the top and bottom lower link and top link. CONSTITUTION:A lower link 6 and a top link 7 are located on an interval part 5 between a pair of left and right floats 3 in a position opposite to the floats 3 and narrowly and simply constructed in the width of the interval part 5. Even if a seedling planter machine body 4 is lifted with the lower link and top link, etc., the lower link is located above the interval part between the floats.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a seedling transplanter. Prior Art and Problems to be Solved by the Invention In a seedling planting machine that connects a seedling planting device to the rear side of a vehicle body in a manner that allows it to move up and down, a float is used to level the seedling planting position of the seedling planting device. , the position is such that it easily comes into contact with the lifting link, which can easily get in the way of raising and lowering the seedling planting device. Means for Solving the Problems The present invention includes a seedling tank (1) that accommodates and supplies seedlings, a seedling planting device (2) that separates and transplants the seedlings supplied from the seedling tank (1), and a seedling planting device (2) that separates and plants seedlings supplied from the seedling tank (1). Float (3) to level the planting soil surface
) etc., the seedling planting machine (4) is attached to the pair of left and right floats (
A pair of upper and lower lower links (
6) and a top link (7), the seedling transplanter is connected to the rear of the vehicle body (8) so as to be able to rise and fall freely.

Inventive Actions and Effects As the vehicle body (8) moves, the seedling planting machine (4) is placed in a descending position, and the float (3) slides onto the soil surface to perform seedling planting work.At this time, the vehicle body (8) ) and a lower link (6) that slopes backward and downward from the bottom, and a float (3) that slides on the ground
), but when the seedling planting machine [4] is raised by the lower link (6) and the top link (7), the distance between the lower link (6) and the float (3) is relatively large.
The vertical distance between and is close to each other. However, these lower links (6) and top links (7)
) is located on the gap part <<5>> at the position facing the float (3), and is configured narrowly within the width of this gap part (5), so that these lower links (6 >> and the top In addition to simplifying the structure of the link (7), it is less likely to get in the way of the seedling transplanting device (4) when it is raised, and the structure of the seedling planting device
This makes it easier to perform lifting control, rolling control, etc. for 81. Embodiment In the illustrated example, the tractor body [8] has a front axle (1 (I) and a rear wheel (11) that is steered by a steering handle (9), and is mounted under the driver's seat fl2l. It has a four-wheel drive configuration in which power is transmitted by the engine (13L), and there is a pair of upper and lower top links (7) on the rear side.
and lower link f6) are pivoted so that they can move up and down freely f141
t+'9 s. This top link (7) is configured such that the lift arm +lIl9 integrated therewith is rotated by a hydraulic device (1'71 piston (11) to move up and down. (+9 is the top link (7)) A rear link that connects the pivot link 21) between the rear end of the lower link (6) and the center of the width of the seedling planting machine (4) with respect to the rolling boss Qδ integrated at the lower end of this rear link (19). The lower link (6) is made of a single rigid body with a predetermined width and thickness, and the width of the rear end is equal to the space between the left and right floats (3). (5
) is formed narrower than the In addition, the top link (7) is similarly constructed from leaf spring material, and the rear end is provided with an elongated hole C!4 into which the pin of the pivot joint (to) is fitted so as to be able to slide forward and backward.Hydraulic system t(7) is a hydraulic pump (2e) installed on the side of the engine (13) and driven by a belt (4e);
It is equipped with a hydraulic cylinder (5) that fits into the hydraulic cylinder (5), a control valve, etc., and is pivoted to the vehicle body (8) by a support shaft QB. (If you push 11 backward, lift arm flG
The seedling planting device can be raised by rotating the top link (7) upward around the pivot point 019 via +, and conversely can be lowered by retracting the piston (1l3). A power take-off shaft +21 is provided at the rear end of the vehicle body (8), and the power take-off shaft +21 and the input shaft of the seedling planting machine (4) are connected by a transmission shaft 0ω, and the rear end of this power take-off shaft Ol The end portion, together with the rear link flLjl, etc., is opposed to the spacing portion (5). The OD is a step, and is provided from the left and right outer parts of the cockpit to the left and right sides of the handle post (to), and on both left and right sides of the handle post circle, it is stepped to the rear side and formed into a stepped part G3, Clutch pedals, left and right brake pedals 09, etc. are provided on this stepped portion 03, and these pedals are provided so that the depressed positions of these pedals, etc., are deep.
aQ is a supply seedling holder that stores seedlings for supply, and is attached to the vehicle body (8).
Provided on the front side of the

The seedling planting device has a seedling planting machine body (4) as its main body, a rolling $Ill (to) is provided on the front side in the left and right center portions, and a seedling tank (1) that moves back and forth in the left and right direction is provided on the upper side. A seedling planting device (2) for separating and planting seedlings supplied from a tank (1) is installed in a four-row planting configuration, and a pair of floats (3) on the left and right are installed in a two-row planting unit. Level the soil surface. Each float (3) has a rear part attached to the seedling planting machine (4)
The float (3) is pivoted so as to be vertically movable, and the left-right spaced portion (5) at the front of the float (3) is set at the left-right center of the fuselage (4).

By positioning the rear link (19l) and lower link (6) in this gap (5), the float (3) can move up and down,
In addition, the front parts of these floats (3) are set at positions where they do not come into contact with the lower link (6), the transmission shaft 01, etc. even if they move up and down together with the seedling planting machine (4).
