Threshing refers to artificially separating fruit from crop stem such as cereals, pulses, etc., and performing this function is called a threshing device. This threshing device is usually mounted on a thresher or combine to perform its function.

The combine is a device that attaches to the threshing machine a cutting device for cutting grain or grass and a traveling device for movement, and a head-feeding combine is typical. These harvesting combines are self-contained grains harvesters that pick up crops while moving the pavement, grab the stem, and grab only the grain into the threshing device for threshing and sorting.

The defoliating combine has many advantages such as simplifying the harvesting system and completing the work at once, so it is very efficient, can finish the work in time and can improve the quality of the harvest. Especially, it is the most suitable harvesting machine for rice which is small size, light weight, less power loss, less loss of grain and less damage than other general combine harvester. However, it is difficult to harvest crops other than rice and barley, and it has a disadvantage of low adaptability to crops with high water content and uneven growth conditions.

On the other hand, the threshing device mounted on the self-extracting combine is generally composed of a threshing barrel and a threshing net arranged to partially cover the lower portion of the threshing barrel. The threshing bucket is composed of a tilt and a plurality of treads formed on the surface of the tread, so that when the tread is rotated, the tread is driven by the hitting action of the tread. The ears, the relief ribs, and the sacs, which are generated by the striking action of the feeders, are rubbed between the feeder and the threshing passage or are subjected to a secondary hitting action, whereby the grains fall off under the threshing net. That is, the threshing net has a plurality of holes for selectively passing the kernels.

The conventional threshing net has a mesh shape having a plurality of rectangular holes. However, such a threshing net is for the purpose of threshing grains such as rice and barley, and other grains, for example, grains of grain, are not suitable for threshing small grains.

Fig. 3 is a perspective view showing the threshing device in an enlarged scale in the combine of Fig. 1, Fig. 4 is a view showing the threshing device of Fig. 3 in the direction of the rotation axis, Fig. 5 is a cross- FIG. 6 is a perspective view showing only a threshing plate of the threshing apparatus of FIG. 3; FIG.

3 to 6, the threshing apparatus 500 includes a threshing container 510, a thresher plate 520, and a plurality of cutting blades 530, . That is, the threshing box 510 hits grains moving through the conveying device 400 while rotating along a rotation axis parallel to the one direction, and the cutting blades 530 are rotated about the rotation axis of the threshing container 510 And the threshing plate 520 can be passed downward by separating the grains and the like from the blown and cut grains.

The threshing container 510 may include a feeding portion 512, a plurality of feeders 514, a rotating shaft module 516, and at least one elastic pressing portion 518.

The feeding part 512 may have a cylindrical shape so as to rotate about the rotation axis. For example, the feeder 512 may be a steel cylinder with a thickness ranging from about 1.2 mm to about 1.6 mm, and may have a diameter ranging from about 360 mm to about 450 mm, depending on the number of lines to be cut, May range from about 710 mm to about 1110 mm.

The feeders 514 may protrude from the outer surface of the feeder 512. The feeders 514 are provided with a function of increasing the threshing efficiency by hitting the grain moving on the threshing plate 520 through the feeder 400 when the feeder 514 rotates along the rotation axis, Can be performed.

Specifically, for example, each of the pairs of teeth 514 may be formed of a hardened wire having a diameter ranging from about 4 mm to about 6 mm, and having an inverted V-shape or U-shape having a height of about 70 mm. The feeders 514 may be disposed in the form of a discontinuous spiral conveyor, and the total number of the feeders 514 may be in a range of usually 50 to 60, and the overlapping of the feeders between neighboring feeders The number can range from two to four.

Meanwhile, the feeders 514 may be composed of semi-swept (cleaned), triangular (reinforced), and double triangular (coupled) teeth. In this case, the semicircle may be arranged at an angle of 10 to 15 in order to allow the grain to smoothly enter the threshing device 500 on the side where the grain is fed for thawing. At this time, the semicircle may have a thickness ranging from about 4.5 mm to about 5.25 mm and a height ranging from about 30 mm to about 45 mm.

The rotating shaft module 516 may be connected to the feeding part 512 to rotate the feeding part 512 along the rotation axis. For example, the rotary shaft module 516 receives rotation power from the power transmission device of the combine vehicle 100 and rotates the feeding part 512 clockwise along the rotation axis at a speed of 460 rpm to 570 rpm .

The elastic pressing portion 518 may protrude from the outer surface of the feeding portion 512 to be spaced apart from the feeding teeth 514 and may be formed of a synthetic resin having elasticity. The elastic pressing portion 518 presses the grains disposed on the threshing plate 520 and rotates the grains or the like through the threshing plate 520 when the feeding portion 512 rotates along the rotation axis By passing further, the threshing efficiency of the grain can be increased.

The elastic pressing portion 518 may have a rectangular parallelepiped shape extending along the one direction and may be formed to have substantially the same height as the feed teeth 514. Meanwhile, the elastic pressing portion 518 may be formed by separating one or two of the feed teeth 514, and then mounting the elastic pressing portion 518 in place.

The threshing plate 520 may include a body portion 522, at least one main latching portion 524, and at least one sub latching portion 526.

The body portion 522 is formed by wrapping an outer surface of the feeding portion 512 of the threshing cylinder 510 at an arbitrary angle about the rotation axis, for example, in a range of about 100 to 150 degrees, And may have a shape elongated along the one direction so as to correspond to the feeding portion 512. The body portion 522 may be formed of an iron plate having a thickness ranging from about 1 mm to about 2 mm.

The body 522 may have a circular or elliptical perforation hole 522a formed in an arbitrary pattern. At this time, the perforation holes 522a may be arranged in a matrix form, but they may be arranged in a form in which the number of other perforated holes adjacent to one perforated hole at the same distance is six, that is, a regular hexagon. Each of the perforation holes 522a may have a diameter ranging from about 6 mm to about 7 mm.

Since the body portion 522 is basically an iron plate, the grain can be strongly supported when the grain is pressed by the threshing barrel 510 rather than in the conventional net shape. In addition, the perforation holes 522a formed in the body portion 522 may have a circular shape or an elliptical shape corresponding to fine grains such as jaws, so that fine grains and the like can be effectively separated and passed through the grains. As such, the body portion 522 is formed of an iron plate capable of strongly supporting the grain, and the perforation holes 522a are formed in a circular or elliptical shape so as to correspond to the fine grains, Is more suited to threshing small grains, and may be particularly effective in separating and passing agglomerates of agglomerates, such as grape clusters.

The main hook 524 protrudes from the inner surface of the body 522 and is formed along the arc, and the body 522 can be divided into a plurality of hoop regions along the one direction. For example, the main latching portion 524 may be spaced apart from the main latching portion 524 so as to be divided into three bending regions along the one direction. At this time, the three threshing regions include an entrance area IA in which the grains are taken in and out, a discharge area OA in which the grains are discharged, and an intermediate area MA (MA) connecting between the entrance area IA and the discharge area OA ).

The main engagement portion 524 may be formed to have a height, for example, about 15 mm, which overlaps the feed teeth 514. At this time, the feeders 514 may be disposed at a position where the feeder 512 does not collide with the main engaging portion 524 even if the feeder 512 rotates along the rotation axis.

The main engaging portion 524 serves not only to divide the body portion 522 into a plurality of threshing regions along the one direction but also to function as a catching portion when the grain moves in one direction, It is possible to suppress the movement and improve the threshing efficiency to some extent.

The sub engaging portion 526 may protrude from the inner surface of the body portion 522 and may have a shorter length than the main engaging portion 524 along the arc. For example, the sub-engaging portion 526 may be formed at a predetermined angle, for example, in a range of about 20 degrees to about 40 degrees, at one side of the body portion 522 facing the transfer device 400 have.

The sub engaging portion 526 may be formed at the same height as the main engaging portion 524 or at a slightly lower height. The feeders 514 may be disposed at a position where the feeders 512 do not collide with the sub engaging portions 526 even when the feeders 512 rotate along the rotation axis as in the main engaging portions 524 have.

The cutting blades 530 may be disposed along one direction on the other side of the body portion 522 opposite to the transport device 400. Each of the cutting blades 530 may be formed to have a height that overlaps with the feed teeth 514. At this time, the cutting blades 530 may be spaced apart from each other so that they do not collide with the feeders 514 when the feeder 512 rotates along the rotation axis.

Thus, the cutting blade 530 can perform a function of finely cutting grains, for example, straw, which are moved by the feeders 514 when the feeder 512 rotates along the rotation axis, As a result, the threshing efficiency of the grain can be further improved.

At least one of the cutting blades 530 may collide with the elastic pressing portion 518 when the feeding portion 512 rotates along the rotation axis. In this embodiment, the elastic pressing portion 518 is provided with at least one passage (not shown) on the inner side so as to be passed without colliding with at least one of the cutting blades 530 when the feeding portion 512 rotates along the rotation axis, Grooves 518a may be formed. Alternatively, at least one cutting edge that may collide with the elastic pressing portion 518 may be formed at a low height that does not collide, or may be removed.

In the present embodiment, the threshing device 500 includes a threshing gerber (not shown) that wraps around the upper and side portions of the threshing container 510 so that the grains to be thrown while being rotated by the threshing container 510 are not discharged to the outside .

Referring to FIG. 7, the threshing plate 520 may further include a plurality of inclined latching portions 528 protruding from the inner surface of the body portion 522.

The inclined latching portions 528 may be formed to have an acute angle with an arc of the body portion 522, for example, between 30 degrees and 60 degrees, and may be spaced apart from each other at regular intervals along the arc. At this time, the slant latching portions 528 may be arranged to form an acute angle with respect to the rotation direction of the feeding portion 512, for example, the clockwise direction about the rotation axis.

The inclined catches 528 may be formed at a lower height than the main catches 524. Specifically, the inclined catches 528 may have a height that does not collide with the catches 514 when the feeder 512 rotates along the rotation axis, for example, the height of the main catching portion 524 And may be formed to have a height ranging from about 1/3 to about 1/2.

The warp engagement portions 528 may be disposed in at least one of the threshing regions formed by the main engagement portion 524. For example, the warp latches 528 may be disposed in the access area IA.

Meanwhile, the elastic pressing portion 518 may be disposed in one of the regions where the warp engagement portions 528 are not disposed, for example, in the middle region MA in the threshing regions. Also, the sub-engaging portion 526 may be disposed in one of the regions where the warp engaging portions 528 are not disposed, for example, the middle region MA among the warp regions.

As the warp latching portions 528 are formed in at least one of the threshing regions, when the grain is supplied to the threshing plate 520 and moves along the one direction, it performs a function of rubbing the moving grain can do. In addition, when the grain moves in one direction, the slanting latches 528 can be guided to move along the space formed between the slant latching portions 528, thereby increasing the movement path of the moving grain .

As described above, the warp engagement portions 528 can rub the grains moving along the one direction or increase the movement path of the grains, so that the gravelling efficiency of the grains can be further improved.
