Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction of a scraping rotary for scraping the surface of old ridges and scraping the soil in a field in a ridge coater.

[0002]

2. Description of the Related Art Conventionally, a ridge coating machine towed to the rear part of a tractor has been known, and this ridge coating machine scrapes the ridges in the field and the surface of old ridges by a scraping rotary having a rotating claw member. The soil was put on the ridge, and the ridge surface was coated with a ridge orthopedic plate with a vibrator. The scraping rotary in such a conventional ridge coater is fixed by rotating several rows of nata claws and blade claws on the rotary shaft, and scrapes the soil of the field scene near the ridge to the upper surface side of the ridge. I was picking up.

[0003]

Such a scraping rotary was designed to scrape and scrape at the same time only by rotating the ratchet claws. However, when grass or the like grows, the scraping amount is small. The amount may be small and the desired ridge may not be obtained, and if the field is muddy with mud etc., the amount of lifting may be small, or it may be lifted with the grass roots in a lump and uneven, resulting in beautiful ridges. Could not be molded.

[0004]

Means for Solving the Problems The present invention is mounted on the rear part of a tractor, scrapes the surface of a field ridge and the surface of an old ridge by a rotary, crushes the soil on the ridge, and coats the ridge surface with a ridge shaping plate. In the ridge coater that hardens, even number of straight blades for cutting, nata claws for crushing and blade claws for jumping up were provided on the rotary shaft of the scraping rotary, and each claw was arranged symmetrically about the rotary shaft. It is a thing. Further, the straight blade is arranged in front of the nata claw and the blade claw, and the radius of gyration of the straight blade is longer than the radii of rotation of the nata claw and the blade claw.

[0005]

By using such means, by driving the scraping rotary, the front blade and the side surface of the former ridge are incised by the straight blade positioned in front, and the weeds and their roots are cut to crush the soil. Then, crushed soil and scooped up with nata and blade claws, pressed by the forming plate to form, and crushed soil enters into the part cut with a straight blade with a large diameter, and the boundary of the new ridge Strong ridges are formed with reliable adhesion.

As shown in FIG. 3, the rotary shaft 34 is projected rearward from the power transmission case 30, and a claw seat is provided at this projecting portion. As shown in FIG. When viewed from the rear side, the straight blade 60, the loose claw 61, the blade claw 6
2 are fixed radially in an even number to form a scraping rotary R, the straight blade 60 is arranged in the front, and the nata claw 61 and the blade claw 62 are arranged in the rear. In the present invention, the blade claws 62 are arranged in a row in a side view every four 90 degrees, and two straight blades 60 are provided between the blade claws 62 and the blade claws 62.
The blade claws 62 and the blade claws 6 are arranged in a staggered manner.
Two nata claws 61 are arranged 180 degrees apart between the two, and all claws are arranged at equal intervals and symmetrically with respect to the rotary shaft 34.

As shown in FIG. 3, the rotary shaft 3
4, the straight blade 60 is arranged forward by the length L1 with respect to the ratchet claw 61 and the blade claw 62, and the working diameter L of the straight blade 60 is L.

The rotation diameter obtained by rotating 4 is 700 mm, the working diameter of the nata claw 61 and the blade claw 62 is 650 mm, or two of the blade claws 62 are 650 mm, and the other two blade claws 62 are 600 mm. However, the straight blade 60 (turning radius L2) is used as a loose claw 61 and a blade claw 62 (turning radius L2).
The length of the ridge coater may be changed depending on the size of the tractor, and the length is not limited, and if the number is even, the number of lines may be longer than 3). Also not limited. The straight blade 60, the loose claw 61, and the blade claw 62 are driven so that the rotation direction of the straight blade 60 is counterclockwise and up-cut.

As shown in FIG. 5, the blade claw 62 has a blade edge 62a formed into a curved line (a straight line is also possible), and a tip portion 62b is bent into a "dogleg" shape in a direction perpendicular to the rotation direction, Alternatively, the tip portion 62b is formed by being curved.
May be fixed by welding. Also,
As shown in FIG. 6, the knuckle 61 has a blade edge 61a formed in a straight line (a curved line is also possible), and a tip end portion 61b is formed into a curved shape by twisting in a "square" shape in a direction perpendicular to the rotation direction. 6
As shown by the two-dot chain line, 0 is the original state in which the nata claw 61 is not bent.

With such a structure, when performing the ridge coating work, the straight blade 60 arranged at the front part cuts and strips the weeds and the roots of the old ridge surface by the rotation of the rotary shaft 34. Then, the nata claw 61 crushes the soil on the surface of the old ridge, and the blade claw 62 scrapes up and covers the upper surface of the crushed old ridge. Then, the vibrating body 2 is molded by the molding plate 27.
It is pressed by 4 and the ridge is formed.

[0018]

Since the present invention is configured as described above, it has the following effects. That is, a straight blade, a ratchet claw, and a blade claw are mounted on the same shaft, the space on the shaft can be effectively used, and the claw can be easily attached and detached, and the scraping rotary can be driven. By the weeds, weeds growing on the fields and on the slopes of the ridges can be cut with a straight blade to cut off the weeds and their roots on the surface, and moreover, a streak-like cut can be made inside the old ridges to break the soil. It becomes easier to do, the soil is crushed by the nata claw, the surface soil crushed by the blade claw is jumped up on the ridge, and part of the old ridge cut by the straight blade with a large diameter remains, The crushed soil is placed on the part and pressed, and the adhesion of the old and new soil on the inner surface of the new ridge is improved.
