Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to a rice transplanter in order to level out unevenness on the screen caused by wheel marks, mud clumps, etc. in front of the device when planting seedlings. Regarding the provided ground leveling device.

[Prior art]

As a soil leveling device for this type of rice transplanter, the following configuration is conventionally known. One of them is, as shown in Fig. 5 (a), on the fixed position member fa) of the traveling aircraft.
Then, the ground leveling member tel is connected to the tip of the leaf spring (b) that extends diagonally backward and downward, and the other one is the upper end of the rear float (d) as shown in Figure 5 (b). The leveling member (e) extending diagonally backward and downward from the
Even with the claw spring (f), the ground leveling members (c, e) are the springs (
b and f), they have a common feature in that they level the field by applying a certain suppressing force to the field. Under conditions where the biasing force is constant, if the field surface is relatively hard, the pressing force of the soil leveling members (c, e) K will be relatively insufficient, resulting in the disadvantage that sufficient soil leveling action cannot be exerted. , If the screen is relatively soft, use a ground leveling member (c,
e) The pressing force exerted by K becomes relatively excessive, causing the field surface to be unduly depressed, resulting in the drawback that a good leveling effect cannot be achieved.

The present invention has been made in view of the above-mentioned actual circumstances Kf[,
The purpose is to provide a soil leveling device for a rice transplanter that can always perform the desired leveling action well and efficiently regardless of the hardness or softness of the field surface.

[Means to solve the problem]

In order to achieve the above-mentioned object, the rice transplanter's soil leveling device according to the present invention includes a non-biased type soil leveling member capable of scraping and eliminating the convex portion of the screen at its lower edge, It has the feature that it is attached to a fixed position member of the traveling aircraft body at the section.

[Action and effect]

The functions and effects exhibited by the above characteristic configuration are as follows.

In other words, the field surface is not leveled by the pressing force of the ground leveling member that is biased downward as in the past, but the field surface is leveled by simply scraping and removing the convex portions of the screen using the non-biased type of leveling member. Since it was made to equalize, 1
Regardless of the hardness or softness of the III surface, it is now possible to always level the field at a desired constant level. Furthermore, a biasing mechanism for the ground leveling member is not required, and the structure can be simplified.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The soil leveling device for a rice transplanter according to the present invention will be explained below with reference to the drawings (FIGS. 1 to 4) K.

As shown in Figures 1 and 2, while the engine (2) is being installed and fixed to the frame mountain provided at the front of the aircraft, a mission case (3) is placed behind the engine Ill, and this mission case A seedling planting device (5) and a seedling stand (6) are installed at the rear end of the planting platform (4), which is installed on the side of (3) and also serves as a machine frame, facing forward and backward. , and a flexible base (3) with a handle (7) attached to both sides of the mission case (3) so that it can swing.
(8) A pair of left and right propulsion wheels 191 pivotally supported at the lower end
, 191, the propulsion wheel +9+, a front float (10 m) at the intermediate front part of +91, and the propulsion wheel (9).
, (9), a pair of left and right rear floats (10b), (
In cooperation with the float group consisting of 10b), a J-row walking type rice transplanter is constructed that sequentially plants three rows of seedlings while supporting the field at an appropriate height.

As shown in Fig. 3, the Juri seedling planting device (5
)'s planting nails (11) correspond to 2 trees each, making it possible to move a total of 3000 trees in one piece! The support shaft Q1 in the lateral direction of the machine is rotatably attached to the button traveling machine so that the soil gathering tool (+2) can swing up and down along the axis of the support shaft 0, and the planting device (5) is attached to the moving machine. The drive rotation shaft of the drive crank arm 04, which is attached to the drive crank arm 04) (in one phrase, the rotating cam (l instantaneous planting claw CII) is attached so that it can rotate integrally so that it is driven in conjunction with the drive crank arm 04). The earth mulching tool support shaft 0
A rocking arm-type mulching tool operation part +17+ extending integrally and rotatably from the field is brought into contact with the rotating cam (Iat,
In addition, the operating portion (17) is connected to the rotating cam (first cam surface of the rotary cam).
16a) Add 1 +1 to the action position where K contacts.
The spring 0 @ that biases the spring 2) downward is attached to the arm (1*) that rotates integrally with the support shaft.Then, the spring 0 @ that biases the spring 2) downward is attached to the arm (1*) that rotates integrally with the support shaft.
The second cam surface (16b) that presses and swings the second cam surface (16b) is connected to a rotating cam (l4K) by a planting claw (which is rotated up and down).
In conjunction with the river, the earth-harvesting tool 02) is operated up and down by the rotational force of the government, and is operated up and down by the spring (1@), and as it moves downward, the seedlings are planted. The muddy soil behind the planted seedlings is pushed toward the side of the planted seedlings, and the mud scraping holes formed by the river are backfilled to prevent the planted seedlings from lodging. It is.

In addition, as shown in FIG. 3, a plate-shaped non-biased leveling plate is installed slightly behind the lowest end of the horizontal support shaft 03) as a fixed position member of the traveling aircraft when the rotational direction is reversed. The upper end edge of member I20) is fixed in a backward downward KM diagonal state, and as the horizontal support shaft 03) is driven to reciprocate, the non-energized ground leveling member (a)) is rotated as shown in the figure. It is configured so that it can be driven and swung back and forth across the vertical plane ff). In addition, the non-energizing type ground leveling member (3) is
It is made of a relatively hard material such as a steel plate or a hard rubber plate, and as the machine moves, its leading edge scratches the convex part of the field surface. The field is leveled by scraping and eliminating.

FIG. 4' shows another embodiment, in which the non-energized ground leveling member-
The fixed position member (13
') K is stuck.

In this case, the ground leveling member (20) does not actively swing back and forth.
