Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a seedling planting machine in uncultivated land, in which seedlings are planted while forming planting grooves in uncultivated land.

[Conventional technology]

In general, planting of seedlings with a seedling planting machine involves planting after cultivating and plowing the field, but recently, in order to save labor on planting work, seedlings are directly planted on uncultivated land. A method of planting has been proposed. However, when planting seedlings directly on hard uncultivated land, there is a problem that a dedicated rice transplanter different from a conventional rice transplanter must be prepared separately.

[Problems to be solved by the present invention]

The present invention has been made in view of the above-mentioned circumstances, and uses a conventional rice transplanter to provide only a rotary groove tool. It is an object of the present invention to provide a seedling planting machine in uncultivated land where seedlings can be planted neatly without using the plant and labor for planting seedlings can be reduced.

[Means for solving the problem]

In order to solve the above-mentioned problems, a technical measure taken by the present invention is a seedling planting machine in which a seedling planting part is mounted on a rear part of a traveling body having front wheels and rear wheels so as to be able to move up and down. A drive shaft is provided in a mounting case extending diagonally forward and downward from the part, and a rotary groove tool is provided on the drive shaft on a line for seedling planting,
The floating groove is located between the rotary groove tool and the seedling planting portion, and the flat planting portion of the float is positioned within the sliding width and provided behind the rear wheel of the traveling machine body. The tools are provided radially with sparse intervals in the rotation direction, slightly wider than the planting claws, and the depth of the groove is deeper than the planting depth of the seedlings in the relative position with the seedling planting part. It is characterized by comprising a rotary blade having such a radial dimension.

[Action of the invention]

When planting seedlings, run the seedling planting machine, and the rotary groove tool provided on the drive shaft in front of the seedling planting section rotates while moving up and down with the seedling planting section as the machine advances. Then, while maintaining the depth of the groove with respect to the planting nail at a predetermined depth, the groove is slightly wider than the planting nail and deeper than the planting depth of the seedling on the seedling planned line. . Next, the planting leveling part of the float slides on the upper surface of the groove created by the rotary groove tool,
After the planting leveling portion has leveled the upper surface of the groove, the planting claws of the planting portion plant the seedlings.

The drive shaft of the rotary groove tool is provided on the mounting case that extends diagonally forward and downward from the seedling planting part, and is located behind the rear wheel, so the mounting structure of the rotary groove tool is simplified. In addition, the drive shaft of the rotary groove making tool is brought close to the field scene, so that the size of the rotary groove making tool itself can be reduced.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Reference numeral 1 denotes a traveling body of a seedling planting machine, in which an engine 5 is mounted on a body frame 4 having a front wheel 2 and a rear wheel 3,

A planting device 10 including a seedling mounting table 7, a seedling planting section 8, a float 9, and the like is mounted at the rear of the body so as to be able to move up and down via a link mechanism 11. The planting apparatus rotates as the body travels. It is the same as the conventional method to scrape the seedlings from the seedling mounting table 7 in which the attached claws 12 reciprocate left and right for each planting plant and plant them in the field.

Reference numeral 13 denotes a power transmission shaft to the seedling planting section 8;
The input shaft 14 from the PTO shaft is interlocked to the shaft, and the transmission shaft 13 is connected to the planter
By connecting to the 16 rotating shafts 17, a power transmission system for operating the planting claws 12 provided on the planter 16 is constructed. 18 is a rotary case, and 19 is a planter arm.

Reference numeral 20 denotes a drive shaft interlocked with a power transmission system of the planting claw 12, and the drive shaft 20 extends from a front portion of the planter case 15 of the seedling planting portion 8 so as to extend diagonally forward and downward. It is rotatably supported by a case 21 and is parallel to the transmission shaft 13. Reference numeral 22 denotes a small-diameter gear provided on the drive shaft 20, and 23 denotes a large-diameter gear provided on the transmission shaft 13.
The drive shaft 20 is rotated at a high speed by being connected via 4.

A rotary grooving tool 25 in the form of a tilling claw is fixed to the drive shaft 20
26, and the rotary groove tool 25 has a planting claw.
The planting of the float 9 located on the planned seedling planting line A extending the seedling planting locus by 12 forward and between the rotary groove tool 25 and the planting part as shown in FIG. The leveling portion 9a is provided behind the rear wheel 3 of the traveling body 1 so as to be positioned within the sliding width. The rotary groove tool 25 has rotary blades provided in the radial direction with a sparse interval in the rotation direction, and the width of the rotary blade is formed slightly wider than the planting claw 12. Along with
The radial dimension of the rotary blade is such that, in the relative positional relationship with the seedling planting section 8, the groove depth when the rotary groove tool 25 is rotated to form the uncultivated land is equal to the planting claw 12. Is larger than the planting depth of the seedling by a predetermined distance h.

When performing the normal seedling planting operation by removing the rotary groove tool 25, the projecting end of the drive shaft 20 or the support shaft is covered with the protective cap 27. Further, if the upper surface of the rotary groove tool 25 is covered with the cover 28, the work can be further performed safely.

Reference numeral 29 denotes a grooving rotator provided on the drive shaft 20. The grooving rotator 29 is disposed at an intermediate position between the adjacent floats 9, and is directly used for water management on uncultivated land simultaneously with the planting operation. Grooves can be formed.

In the above-described configuration, when the seedling planting operation is performed in the current seedling planting operation, the rotary groove forming tool 25 provided at the front portion of the seedling planting section 8 along with the running of the airframe is used. It rotates to form a planting groove on the line for seedling planting, but the rotary groove tool provided in front of the seedling planting section 8 moves up and down together with the seedling planting section 8 so that it is always planted. The groove can be formed at the same depth with respect to the claw 12, and the rotary groove tool 25 is pivotally supported by the mounting case 21 close to the planting claw 12, so that the aircraft may meander. Even so, the planting claws 12 can satisfactorily plant the seedlings in the planting grooves. Since the rotary groove tool 25 is provided on the line where the seedlings are to be planted and within the width in which the float planting leveling portion 9a slides, the rotary groove tool 25 is formed in the groove formed by the rotary groove tool 25. The planting is performed after the float is slid on the upper surface and leveled at the planting leveling portion 9a. In addition, since the rotary groove tool 25 is slightly wider than the planting claw 12 and forms a groove deeper than the planting depth of the seedling, the seedling can be easily planted by rotating the planting claw 12. Since the root of the seedling a is supported by the inner surface of the groove as shown in FIG. 9, the seedling can be reliably held in an appropriate standing posture. Therefore, even in the uncultivated land, the seedlings can be planted neatly without using a special rice transplanter or the like.

A grooving rotary body provided on the drive shaft 20 at the same time as the planting operation
29 creates a groove for water management in the middle position of the float 9, which can save labor in grooving work. In addition, since the groove is formed in uncultivated land, the groove is not broken and smooth. Water management.

[Effect of the invention]

The present invention relates to a seedling planting machine in which a seedling planting part is attached to a rear part of a traveling body having a front wheel and a rear wheel so as to be able to move up and down, in a mounting case extending diagonally forward and downward from the seedling planting part. A drive shaft is provided, and a rotary grooved tool is mounted on the drive shaft on the planned seedling planting line, and a float planting level portion located between the rotary grooved tool and the seedling planting portion slides. The rotating groove is provided radially with a sparse interval in the rotation direction, and is slightly wider than the planting claw. Since it is characterized by having a rotary blade having a radial dimension such that the depth of the cultivation groove is deeper than the depth of planting of the seedlings in the relative positional relationship with the planting portion, it is as follows. It has a great effect.

Since the rotary groove tool is attached to the seedling planting portion via the mounting case, even if the seedling planting portion moves up and down, it moves up and down together with the seedling planting portion. Is maintained at a predetermined depth, and the planting claws can satisfactorily plant the seedlings in the planting grooves even when the body is meandering.

Since the rotary gutter is located on the line where the seedlings are to be planted and within the width in which the leveling portion of the float slides,
Planting can be performed after leveling with the leveling part of the float that slides on the upper surface of the groove created by the rotary groove tool,
Even though the grooving tool is for planting seedlings in the crushed and plowed sites, it is possible to perform orderly planting.

Since the drive shaft of the rotary groove tool is provided on a mounting case extending obliquely forward and downward from the seedling planting portion and the groove tool is positioned behind the rear wheel, the mounting structure of the rotary groove tool is provided. And the drive shaft of the rotary groove-making tool can be brought close to the field scene to reduce the radial dimension of the rotary blade, and the rotary groove-making tool itself can be reduced in size. It is easy to transport and store the rotary groove tool.

Since the rotary groove-making tool is provided with rotary blades provided radially with a sparse spacing in the rotation direction, the soil is not entangled at the time of groove formation, and the soil from the side is smaller than a disk-shaped blade. It is difficult to receive pressure, and an orderly groove can be formed.
