DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scraping wheel structure for a reaper such as a combine.

[0002]

2. Description of the Related Art In general,
The raking wheels arranged on the stalk culling path of this seed mower are provided in a one-to-one pair so as to mesh with each other and rake the two stalk culms. Discloses a method in which a scraping wheel disposed on a stem stalk scraping path at an end of a cut ground is driven alone to scrape the remaining one strip.
However, when the mud adheres to the raking wheel during the mowing operation in the wetland, the mud adhering is naturally removed by the one-to-one pair of raking wheels due to the discharging action by the meshing, but the raking wheel is driven alone. The mud adhering to the scraping wheel is not subjected to any soil removal action, so it gradually accumulates and hinders the scraping action of the scraping wheel. There was. Further, during the wet field mowing operation, mud also adheres to the cutting blade disposed below the raking wheel, but the mud is adhered to by using the rotating force of the raking wheel. What has been proposed in the past. In other words, the scraping wheel is integrally provided with a soil removal plate close to the cutting blade, but conventionally, since the soil removal plate is screwed to the scraping wheel, the scraping wheel and the soil removal plate are combined with each other. In addition, there is a concern that the stalks and stalks may be carried around and hinder the scraping action. In addition, the stabs and stalks may exert an excessive force and deform the earth removal plate.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made with the object of providing a scraping wheel structure of a reaper that can eliminate these disadvantages. In a reaper, which independently drives a raking wheel disposed on a stalk-pull raking path at a cut ground side end, a plurality of lugs radially projecting from the raking wheel are formed in a substantially round bar shape. the formation be Rutotomoni a predetermined lag,
By independently driving the scraping wheel disposed in the stem culm scraping path at the end of the already-cut ground where the soil removal plate adjacent to the cutting blade disposed below is integrally welded. A plurality of lugs projecting radially from the raking wheel are formed in a substantially round bar shape. And, according to the present invention, with this configuration, mud is prevented from adhering to the scraping wheel driven alone to solve problems such as clogging of stems and the like, and a scraping plate is provided on the scraping wheel, The invention prevents the stem from being stuck between the raking wheel and the earth removal plate, thereby preventing rotation of the stem and deformation of the earth removal plate.

[0004]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a five-row cut combine, which is a pre-processing unit 2 for cutting stem culms, a threshing unit 3 for threshing cut stem culms, and a discharging process for threshed culms. A post-processing unit 4, a crawler-type traveling unit 5, and the like are provided.

[0005] The pre-processing unit 2 includes a divider 6 which is juxtaposed at a predetermined interval at the front end of the fuselage so as to stalk the stem and stalk to the number of cutting streaks, and a stem and culm introduced between the dividers 6. Device 7, a cutting blade 8 for cutting the stem of the raised stem and stem, a scraping device 9 positioned above the cutting blade 8 for scraping the stem and stem, and a scraping device 9 for scraping the stem and stem. A horizontal conveying device 10 for merging the inserted stems and lumps at the left end side of the pre-processing unit 2, and a stem and culm conveying device (not shown) for conveying the merged stems and culms to the threshing unit 3 while changing the posture from a vertical position to a horizontal position. ) Etc. are provided,
Among the dividers 6, the intervals between the dividers 6, 6 for weeding the row at the end of the cut ground are set wider than other dividers in order to prevent uncut leaves as much as possible.

Reference numeral 11 denotes a squeezing wheel (star wheel) constituting the squeezing device 9;
1 is provided as a pair so as to mesh with each other and scrape the two stems and stems. However, since the number of cutting strips of the combine 1 is set to an odd number, the number of cut strips is set to the scraping path at the end of the already cut ground. Is provided with a single scraping wheel 12 so as to scrape the remaining one strip. In other words, on the same axis of the scraping wheel 12, a driven sprocket 15 which receives power from a driving sprocket 14 via a stock transfer chain (a roller chain with projections) 13 is integrally connected, and the driven sprocket 15 is connected to the driven sprocket. 15 alone drives the single scraping wheel 12 alone. By the way,
In the one pair of squeezing wheels 11, only one squeezing wheel 11 is driven, and its power is transmitted to the other squeezing wheel 11
The transmission is engaged.

The scraping wheels 11 and 12 have:
Although a plurality of lugs 11a and 12a that have a stem-pulling action are radially projected at predetermined intervals, in the one-to-one set of scraping wheels 11, gear teeth are taken into consideration in consideration of meshing between the wheels. While the lug 11a having the shape of resin is integrally formed of resin, the driven sprocket 15
A round bar-shaped lug 12a is integrally welded to a disc-shaped base plate 12b connected to the base plate 12b. That is, in the single scraping wheel 12 which is not subjected to the earth discharging action by the meshing
By adopting a round bar shape in which the mud is hard to adhere and the adhered mud is easy to fall, it is possible to prevent the mud from adhering to the raking wheel 12 at the time of mowing the wetland. Further, by making the lug 12a a round bar shape having the same width at the distal end and the width at the proximal end, a wide valley between the lugs 12a can be ensured. Is set to approximately half the wheel radius (the length from the center of the wheel to the tip of the rug), so that the valley can be further widened to greatly increase the allowable amount of mud and stalks. You can get it.

Further, reference numeral 12c denotes an earth removal plate provided on the independently driven scraping wheel 12.
“c” protrudes downward so as to approach the cutting blade 8 disposed below, and scrapes off the mud adhering to the cutting blade 8 as the raking wheel 12 is driven. Is integrally welded over the entire length of the lug 1a. That is, it is possible to prevent a gap from being formed between the earth removal plate 12c and the lug 12a,
2a and the lugs 12a which are inclined backward in the radial direction (a posture in which the proximal end is ahead of the distal end) with respect to the radial direction.
The mud adhering to 2c can be removed to the outside using centrifugal force.

In the embodiment of the present invention configured as described above, there is a possibility that mud may adhere to the rake wheels 11 and 12 as the stems are raked. in 11, it adheres mud undergoing dumping action by engagement is to be eliminated, that the adhesion of the mud is locked anti even in a single scraping wheel 12 not subjected to the dumping action of the engagement Become. That is, the scraping wheel 12
The rug 12a is formed in a round bar shape to which the mud is difficult to adhere and the adhered mud is easy to fall. As a result, decrease in scraping ability based on attachment mud and sealed anti generation of stem稈詰Ri with decreasing scraping ability can be achieved on improvement of scraping performance.

[0010] Moreover, since the valley portions between the lugs 12a is secured wide, it is possible to measure the upper direction of the scraping performance greatly increases the scraping capacity of adhering tolerance and Kuki稈mud.

Further, since the earth removal plate 12c for removing the mud adhering to the cutting blade 8 is integrally welded to the lug 12a, the earth removal plate 12c is screwed as in the conventional case where the earth removal plate 12c is screwed.
Therefore, no gap is formed between the stub culm and the rug 12a, so that the stalk stalk stabbed between the dumping plate 12c and the rug 12a is carried around to inhibit the scraping action, or Thus, the inconvenience that the earth discharging plate 12c is deformed can be eliminated .

Further, in the above-described embodiment, the earth discharging plate 12c is provided.
Is tilted backward with respect to the radial direction,
The mud adhering to c can be removed by using the centrifugal force. As a result, it is possible to prevent a problem that the mud adheres to the discharging plate 12c in a piled state and lowers the discharging operation of the cutting blade 8.

[0013]

In summary, since the present invention is constructed as described above, a plurality of lugs projecting radially from the raking wheel are provided while the raking wheel is independently driven. It is formed in a substantially round bar shape. In other words, the rug shape is such that the mud is difficult to adhere and the adhered mud is easy to fall, so that mud does not adhere to the scraping wheel in a pile even during the mowing work in the temporary wetland. Accordance connexion, or decreased by connexion scraping ability to adhere mud, can prevent a problem that or generating a wake connexion stem稈詰Ri to reduced scraping ability, as a result, to the upper direction of the scraping performance of the harvester be able to.

[0014] Further, in providing the earth removal plate for removing the mud adhering to the cutting blade to the lug, since the earth removal plate is integrally welded to the lug, a gap is formed between the earth removal plate and the lug. caused it rather than name, Kuki稈between a blade and the lug can be reliably prevented that the stick, follow go-between, on top that can prevent a rotating basis of Kuki稈, is stabbed One stems by the culm go-between a blade The inconvenience of deformation can be eliminated .
