Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a land leveling device for a riding rice transplanter, and particularly to an improvement of a divided land leveling float.

[Conventional technology]

BACKGROUND ART A plurality of soil leveling floats provided under the main body of a rice transplanter are generally known.

[Problem that the invention attempts to solve]

This soil leveling float supports the rice transplanter body stably and slides on the flexible rice field surface, levels the rice field surface on which seedlings will be planted using the planting body installed on the rice transplanter body, and removes muddy soil. There is a need to reduce the impact on extrusion and adjacent planting positions, and to eliminate wheel marks on the passenger vehicle that pulls the rice transplanter.

[Means and actions for solving problems]

The present invention was developed based on the above-mentioned circumstances, and consists of a center leveling float 8 for a sensor located between the left and right wheel widths of a traveling passenger vehicle body, and a side leveling float disposed on the left and right outer sides of this center leveling float 8. 9, 9 are provided, and the shape of the side soil leveling floats 9, 9 is cut out so that only the rear portions of the left and right middle portions are cut forward, and both the left and right sides are configured in a straight line to form a single row planting area land leveling configuration. By arranging the wheels in front of this unnotched longitudinally long leveling surface section, there is no need to make the left and right widths of the side leveling floats 9, 9 extremely wide. Since the area is straight, muddy water flows smoothly and does not have any negative impact on the planting area, and wheel marks on passenger cars are reliably erased, allowing highly accurate planting work.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a passenger vehicle body, and a rice transplanting device 4 is attached to the rear of the passenger vehicle body 1 via a lifting link 2 operated by a hydraulic cylinder 3. As shown in FIG. The rice transplanting device 4 includes a main body 5, a seedling tank 6 supported by the main body 5 so as to reciprocate a predetermined distance in the left-right direction, and a seedling tank 6 that rotates along a predetermined trajectory in the vertical direction and is stored in the seedling tank 6. a planting body 7 that takes out the seedlings one by one from the lower end and plants them on the rice field; and a center soil leveling float 8 disposed below the main body 5.
It also has side leveling floats 9, 9, etc. In addition, as is clear from FIG. 2, the rice transplanting device 4 divides the seedling tank 6 into three sections in the front and rear, and the planting body 7 is divided into three partitions in a horizontal row at predetermined intervals corresponding to each partitioned seedling tank. , and those in between are
It is located at the center of the main body 1 in the width direction. As shown in FIG. 2, the center leveling float 8 has a planar shape with a wide part 8a at the front and a narrow part 8b at the rear, and the rear end of the narrow part 8b is connected to the central planting body 7. It extends close to the narrow part 8b.
The rear part of the wide part 8a is attached to the main body 5 via a link body 10 so as to be rotatable back and forth and vertically movable, and the center part of the wide part 8a is attached to the main body 5 via a link body 11 so as to be movable up and down. Float 8 at body 11 position
A sensing (sensor) mechanism is provided that senses the vertical movement of the rice transplanter 4 and moves the rice transplanting device 4 up and down via the lifting link 2. The side leveling floats 9, 9 have a planar shape with a front portion extending from a position slightly outside the extension line of both side edges of the wide portion 8a of the center leveling float 8 for the sensor to slightly inside the outer end of the seedling tank 6. A wide part 9a having a width and extending in front of the planting body 7 on both the left and right sides and having a width slightly wider than the wide part 8a of the center soil leveling float, and both side edges of the wide part 9a extending rearward in a straight line, Narrow width parts 9b, 9c are formed by notching forward only the rear part of the left and right middle parts so that the planting bodies 7 on both the left and right sides are located inside, and the narrow width parts 9b, 9c are connected to the main body 5. It is attached via a link arm 12 so that it can be rotated back and forth and moved up and down,
The wide part 9a is attached to the main body 5 via a link body 13 so as to be vertically movable. Further, the front and rear wheels of the passenger vehicle body 1 are arranged in front of the wide portion 9a and the narrow portion 9c. Furthermore, a planting depth adjustment lever 1 is attached to the rotation shaft 14 of the link arm 12.
5 is attached, and the rotating shaft 14 and the link body 10 of the center soil leveling float 8 are connected by a link rod 16, and the side leveling floats 9, 9 are moved up and down by the planting depth adjustment lever 15. When the planting depth is adjusted, the center leveling float 8 also moves up and down at the same time. In the rice transplanter having such a configuration, the passenger vehicle body 1
When the rice transplanting device 4 attached via the lifting link 2 performs planting work, the lifting link 2 moves the center soil leveling float 8 and the side leveling floats 9.
While touching the rice field and sliding while being towed by the passenger vehicle body 11, the planting work of three rows is performed by the planting body 7. At this time, the center leveling float 8 levels the field in front of the central planting body 7, and when the passenger vehicle body 1 moves up and down due to irregularities in the hardboard, etc., the center leveling float 8 senses this up and down movement and links the lifting and lowering 2, the rice transplanting device 4 is moved up and down to keep the planting depth of the planting body 7 constant. In addition, the wide part 8 of the center leveling float 8
a is much narrower than a conventional center leveling float, and therefore pushes out far less mud. In the side soil leveling float 9, the wide part 9a levelens the field surface in front of the planting body 7 on both the left and right sides, and also prevents the movement of the machine's center of gravity to the left and right caused by the seedling tank 6 reciprocating from side to side. Together with the narrow width parts 9b and 9c, it is supported without tilting to the left or right, and the wheel marks of the front and rear wheels of the passenger vehicle body 1 are leveled by the wide width part 9a and the narrow width part 9c, allowing stable planting work to be performed. Furthermore, there is an appropriate gap between the narrow part 8b of the center leveling float 8 and the side leveling floats 9, and the inner edge of the side leveling float 9 is formed in a long straight line in the front and back. The mud flowing on both sides of the soil leveling float 8 does not disturb the leveled surface of the center leveling float 8.

[Effect of the idea]

As explained above, according to the land leveling device of the riding type rice transplanter of the present invention, the center leveling float 8 and the side leveling float 9 of the side leveling floats 9, 9 provided on the lower side of the main body 5 of the rice transplanting device 4, 9, the planting body 7 is positioned by cutting out only the rear portions of the left and right intermediate portions forward, and forming both the left and right sides in a straight line, and creating a leveled surface that is long in the front and rear without notches. Since the wheels of the vehicle body 1 are positioned in front of the side leveling floats 9, 9,
The left and right width of the field can be leveled by planting in a single row, so there is no need to make it extremely wide.Moreover, since both the left and right sides are straight, muddy water flows smoothly down to the rear end, and it can be easily flowed to the planting area. The influence of muddy water is eliminated, and since the wheels of the traveling vehicle body 1 are located in front of the long grading section before and behind the side grading floats 9, 9, wheel marks can be reliably leveled, and the grading can be done with these side grading floats 9, 9. Seedlings that are planted at the notch position in the cutout area will not be transplanted to the front running wheel marks, allowing for accurate transplantation.
