Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a walk-behind rice transplanter, and more particularly to a walk-behind rice transplanter that improves mud removal between wheels and swing arms. ′ A walk-behind rice transplanter has a swing arm with pivoted ends on both sides of the body equipped with an engine, etc. The interior of this swing arm is hollow and houses a chain suspended on a chain wheel. The shaft of the chain wheel corresponding to the other end extends outside the swing arm, and the wheel is attached to this.Furthermore, a center float is located between the chain wheels, and the width dimension of this center foot is The spacing is larger than the spacing between rows, making it possible to level the ground where seedlings will be planted.

With this type of rice transplanter, in fields where the tiller is deep, or in fields where the tiller is locally deep, the wheels go deep into the field and swing as shown in Figures 1 and 2. The arm 1 and the center float 2 are almost on the same level, and mud gets stuck between them, increasing running resistance and making rice transplanting difficult.

Therefore, this invention aims to improve mud removal between the swing arm and the center float to reduce the resistance while driving in the field. This is characterized in that the width of the portion corresponding to the portion sandwiched by the upper swing arm is smaller than the spacing between the planting rows.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in FIG. 3 of the attached drawings will be described below. First, Figure 3 is a schematic plan view of a four-row walking type rice transplanter. - There is a swing arm 12 which also serves as a base, and the output shaft of the reducer is a pivot shaft 13. Further, at the free end of the swing arm 12, a skewer shaft 15 is attached to an axle shaft 14 which also serves as a chain wheel shaft.

Seedling stands 1 and 6 are attached to the rear of the pedestal 11. It is designed to be able to move forward in a direction perpendicular to the direction of progress of the FB planting work, and the seedling mat can be planted by cutting out one seedling mat from the four cutting ports 16a using a planting machine (not shown). It is composed of

Further, on the outside of the wheels 15 attached to the fuselage 11, side floats 17.17 are provided with swing arms 17a.
, 17a. This side float 11 has the function of supporting the rice transplanter with buoyancy and the function of leveling the soil at the planting position of the seedlings, and has leveling pieces 17b protruding inward toward the wheels.

In the case of a 4-row rice transplanter, the side float 17°11
will clear the ground in locations corresponding to the planting rows on both sides.
Since the position corresponding to the two middle rows is leveled with a center float, this center float needs to have a width that spans the two planting rows. It has a width that can level the ground for two rows, and a center float 20 is attached to the fuselage 11. As mentioned above, the front end of this center float 20 is a ground leveling part 21 with a width spanning two rows of planting, and the swing arm 1
There is a narrow support portion 22 from the vicinity of the pivot point 2 to the rear end. A circle between both sides of the support portion 22 and the inward direction of the swing arm 12! In other words, the width W of the support portion 22 is made smaller than the spacing P between the planting rows to widen the spacing 1IiG.

The middle ring 15 is on the outside of the swing arm 12, and is located on the outside of the two planting rows closer to the center, avoiding the two planting rows.

Furthermore, it is preferable that there is no obstacle to the flow of mud on the inside of the swing arm 12, and in the second embodiment shown in FIG. It is divided into a sensing float 23 to be moved and a support float 24 to support the driving reaction force, and a wide space 1llS without a 70-t is formed between the swing arm 12.12, and the support float 24. Set the width W to be smaller than the li spacing P of the planting row.

Since the walk-behind rice transplanter of the present invention has the above-described configuration, when the swing arm 12 rotates downward and the wheels 15 descend in a deep field, the center float 20
The swing arm 12 approaches the
There is a relatively large gap between the center 70 and the side surface of the swing arm 12 on the inside of the swing arm 12, or the center 70 and the center 20 are divided into a sensing float 23 and a support float 24. ', 1I of both floats
Since llIi is the space S inside the swing arm 12, mud flows into the inside of the swing arm 12 as the rice transplanter advances, and the mud can be handled by passing through the rear, and the space inside the swing arm is The mud will not become clogged with clumps.

As is clear from the above explanation, the walk-behind rice transplanter of the present invention is constructed by forming a space between the swing and the center float on the inside of the swing arm and the center float. To reliably prevent mud clogging that tends to occur inside a swing arm to which a wheel is attached even in a farm field or a farm field where the plowing platform is locally deep.・
