本考案は田植機の車輪後方にあつて、車輪によ
つて生じた圃場の凹凸をならして整地する車輪跡
均平具に関する。[Detailed Description of the Invention] The present invention relates to a wheel track leveling tool that is located behind the wheels of a rice transplanter and smooths out unevenness in the field caused by the wheels.
従来、このような車輪跡均平具は車輪跡均平具
全体が地表に対し緩傾斜になるように取付けられ

地される場合、圃場が柔い時は満足すべき状態に
整地されるが圃場の硬い場合は車輪跡均平具の対
地角度が小であるため、均平具が地表の突部を乗
りこえてしまい充分な整地が行えず、硬い圃場も
充分に整地しうる整地具の出現が要望される。 Conventionally, such wheel track leveling tools have been installed so that the entire wheel track leveling tool has a gentle slope with respect to the ground surface. It is used to smooth out unevenness in the field. When leveling the ground with this conventional leveling tool, when the field is soft, the ground is leveled to a satisfactory level, but when the field is hard, the leveling tool has a small angle to the ground. There is a need for a soil leveling tool that can adequately level even hard fields because the field surface gets over protrusions on the ground surface, making it impossible to level the ground sufficiently.
本考案はかかる要望にこたえるべくなされたも
のである。 The present invention has been devised to meet such demands.

A pair of left and right rear wheels 2 configured to straddle the road;
A planting device 5 with 6 plants is installed in parallel in the left and right direction with three ground floats 4 that can swing up and down within a certain range using the rear end side as a fulcrum at the rear of the traveling body 3 having 2. It is connected and supported via a quadruple link mechanism 6 and a hanging link mechanism 7 which is approximately in the shape of an inverted trapezoid when viewed from the front so that it can be driven up and down and rolled. As shown in FIGS. 2 to 4, a link mechanism 9 that supports the planting transmission case 8 of the planting device 5 so that the planting depth can be adjusted is located at the center of the body width. The frame 11, which is approximately U-shaped in plan view, is extended from near the pivot point of the front bent link 10 of the grounding float 4 located at the left and right sides to the outside, and its free ends 11a, 1
The floats 1a extend to the center between the adjacent floats 4, 4 and 4, 4, and the free ends 11a, 11a of the frame 11 are provided with the floats 4, 4 and 4, 4. Wheel track leveling tools 12, 12 for backfilling and leveling the formed groove-shaped wheel marks are mounted on a horizontal axis P,
The frame 11 is pivotally mounted to be able to swing up and down around P, and near both free ends 11a, 11a of the frame 11, there is a screw thread for elastically biasing the wheel track leveling tools 12, 12 in the direction of contact with the ground. Coil spring 13,1
A locking member 14, 1 has a plurality of engagement grooves 14a, 14a, which can engage one end portion 13a, 13a of 3.
4, and then the torsion coil spring 1
By changing the engagement position of the one end portions 13a, 13a of the springs 13, 13, the pressing force of the wheel mark leveling tools 12, 12 against the mud surface by the springs 13, 13 can be adjusted in accordance with the hardness of the mud surface. are doing. Ground leveling tool 12,
As shown in FIG. 3, reference numeral 12 denotes a scraping earth removal plate 12a that is installed at a steep slope with respect to the ground surface, and a scraping earth removal plate 12a that is located behind the scraping earth removal plate 12a and extends downward from the scraping earth removal plate 12a. The ground leveling plate 12b is installed on a gentle slope. To be more specific, the earth leveling tool 12 is formed by bending a single plate material at an acute angle to form the scraping earth removal plate 12.
a and the ground leveling plate 12b, and the lower end of the scraping earth removal plate 12a and the front end of the leveling action portion of the ground leveling plate 12b are provided in a state that they are separated from each other. In other words, the scraped earth removal plate 12a extends downward from the above-mentioned bent portion in a cantilevered manner. Further, the ground leveling action portion of the ground leveling plate 12b is provided in a rake shape to improve mud removal.
削り取り排土板の対地角度は60〜80゜、整地板
の対地角度は30゜以下が好ましいが、前者を90゜又
はこれよりやゝ大きくして実施するもよい。 The angle to the ground of the scraping earth removal plate is preferably 60 to 80 degrees, and the angle to the ground of the leveling plate is preferably 30 degrees or less, but the former may be set to 90 degrees or slightly larger than this.
尚、削り取り排土板12aと整地板12bとの
間は必要に応じステー(図示せず)により補強す
る。 Note that the space between the scraping earth removal board 12a and the ground leveling board 12b is reinforced with a stay (not shown) if necessary.
尚、前記後車輪2,2の移動によつて泥面に形
成された溝状の車輪跡は、左右両側に位置する接
地フロート4,4にて埋め戻し整地するべく構成

する田植機の車輪跡均平具である。 In summary, the present invention provides a scraping earth removal plate steeply inclined to the ground surface on the side in the direction of movement of the aircraft, and also provides a ground leveling plate at a gentle slope to the ground surface behind and below the scraping earth removal plate, and the lower end of the scraping plate. This is a wheel trace leveling tool for a rice transplanter, characterized in that the front end of the soil leveling action part of the soil leveling plate is separated from the front end of the soil leveling action part of the soil leveling plate.
