Description

ROTARY BLADE USING IN AGRICULTURAL APPARATUS < RTI ID = 0.0 >

The present invention relates to a rotary blade for an agricultural machine equipped with a seeding machine, more specifically, a rotary blade for grinding the soil to be sown and removing the soil adhered to the plow when sowing and planting the grooves.

Rotary blades for agricultural machinery are mainly used for cultivating tillage by installing on cultivators or the like. Depending on the shape, they can be classified into small, mid, and L-shaped blades. In addition to tillage machines, And the like.

1, a plow C and a rotary blade are installed at the same time. When a rotary blade is used between the plow C and the plow C, When the seeding machine is pulled by the cultivator, the plow (C) digs soil of a certain depth to form a sowing groove, and seeds such as seedlings are arranged one by one in the sowing machine of the sowing machine, When falling into the groove, the rotary blade rotating by the power of the tiller pulverizes and scatters the soil to the rear of the plow C to cover the seeding groove with the soil, thereby sowing.

However, since the conventional rotary blade is mainly used for cultivating paddy fields or for tilling soil which is hardened and crumbling, the iron plate of a certain thickness is formed by a simple bending molding such as a cone shape or an L shape, There are some inconveniences.

That is, as shown in FIG. 2, in the case of a traction type seeder in which a plow C is positioned between rotary blades rotated by the power of the tiller, highly viscous soil is attached to the entire surface of the plow C, When the attached amount is gradually increased so as to fill the space between the plow C and the rotating rotary blade, not only the rotational load of the rotary blade rotating by the power of the tiller increases but also the smooth progress of the seeder pulled by the tiller So that normal seeding can not be achieved.

The present invention relates to a rotary blade provided under a farming machine having driving means and performing a tilling crushing operation while being rotated by driving means of an agricultural machine,

A coupling flange 101 having a plurality of coupling holes 101a is integrally formed at one end and a central hole 101b having a polygonal cross section is formed at the center of the coupling flange 101 so that the drive shaft 5 having a polygonal cross- A boss 1,

A plurality of through holes 201 coinciding with the coupling holes 101a formed in the coupling flange 101 of the boss 1 and a center hole 202 coinciding with the center hole 101b of the boss are formed at the central portion, A curved blade 2 which is formed by bending at a predetermined angle and which is in close contact with one surface of the coupling flange 101 of the boss 1 at the center,

The engaging holes 301 and 302 corresponding to the plurality of through holes 201 and the center hole 202 formed in the curved edge 2 are formed and at both ends thereof, A scraper 3 formed so that the removing blade 303 protrudes and is brought into close contact with one surface of the curved blade 2,

A bolt 4a and a nut 4b which are assembled together so that the boss 1, the curved blade 2 and the scraper 3 can be disassembled and assembled at once.

The present invention is characterized in that when the sowing machine is attached to a sowing machine such as a plowing machine for the purpose of sowing or the like, the curved blade 2 rotates while performing the tilling sowing and at the same time, the scraper 3 rotates the soil attached to the plowing machine Since it is scratched and removed, it is possible to reduce the rotary load of the rotary blade even when sowing under a variety of soil such as clayey soil, watery soil, and soil having many foreign materials such as rice straw, which not only improves the durability of the machine, So that the seeding operation can be carried out smoothly.

FIG. 2 is an exemplary usage plane view showing a problem that occurs when a conventional rotary blade is used together with a plow
3 is a perspective view of a preferred embodiment of the present invention;
4 and 5 are exploded perspective views according to a preferred embodiment of the present invention
6 is a plan view of a use state according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

It is to be noted that like elements in the accompanying drawings are denoted by the same reference numerals throughout the drawings as possible, and detailed descriptions of well-known functions or known configurations that may unnecessarily obscure the gist of the present invention are omitted. Come on.

As shown in FIGS. 3 to 6, the present invention relates to a boss 1, a curved blade 2, a bolt 4a which can be disassembled and assembled with a scraper 3, And the nut 4b.

At this time, the boss 1 is integrally formed with the coupling flange 101 having a plurality of coupling holes 101a at one end thereof, so that the boss 1, the curved blade 2 , When the scraper 3 is joined together, the boss 1 and the curved blade 2, which are in close contact with each other, closely contact each other.

Since the center hole 101b to which the drive shaft 5 having the polygonal section of the drive means is coupled is formed at the center of the boss 1, the drive shaft 5 is coupled to the center hole 101b of the boss 1 When the rotational force of the driving shaft 5 is transmitted to the curved blade 2, the coupling flange 101 integrally formed at one end of the boss 1 is brought into close contact with the curved blade 2 to be engaged with the coupling means 4a and 4b So that the rotational force of the drive shaft 5 can be transmitted to the curved blade 2 without loss.

On the other hand, a plurality of through holes 101 and a plurality of through holes 201 and 202 coinciding with the center hole 101b formed in the coupling flange 101 of the boss 1 are formed at the center, The curved edge 2 which is in close contact with the engaging flange 101 and is engaged with the engaging flange 101 by the bolts 4a and 4b is formed by bending both ends at a predetermined angle, It is possible to effectively perform a tilling stiffening effect which tends to break the ground soil by grinding or hardening, and can effectively perform the work of scattering the soil for sowing or the like.

It is also possible to form coupling holes 301 and 302 which correspond to the plurality of through holes 201 and 202 formed in the curved blade 2 and to remove the soil at opposite ends in the direction opposite to the forming direction of the curved blade 2 The scraper 3 formed in such a manner that the blade 303 is protruded and is in close contact with one surface of the curved blade 2 is rotated like the curved blade 2 when the scraper 3 is attached and used as shown in FIG. The soil removing blade 303 of the scraper 3 rotates in front of the plow C while scraping off the soil adhering to the front of the plow C while the curved edge 2 is performing the plowing shovel, C to prevent the adherence of a large amount of soil.

Accordingly, when a traction type planter provided with a plow C positioned between rotating rotary blades driven by the power of the tiller is used in the agricultural land of highly viscous dirt, the viscous soil is sown on the front of the plow (C) It is possible to smoothly perform the seeding operation by smoothly advancing the seeding machine to be towed by the tiller or the like.

In the meantime, when the curved blade 2 or the scraper 3 is worn out for a long period of time due to the combination of the bolt 4a and the nut 4b, It is possible to selectively replace the blade 2 or the scraper 3 so that the cost of the rotary blade can be reduced.
