Teeth Adjustable Threshing Drum for Combine}

The present invention relates to a variable threshing bin for a combine, and more specifically, by optimizing the threshing arrangement by changing it according to the type of crop to be harvested and the harvesting speed, equal striking is achieved without the occurrence of missed parts. This relates to a rapidly deformable threshing bin for combines that can minimize threshing losses.

In general, a combine is a harvesting machine that drives over farmland to cut down crops such as rice, barley, and wheat, and then performs threshing and sorting operations.

As schematically shown in Figure 1, this combine includes a traveling device 100 formed in an endless track, a threshing device 200 mounted on the traveling device 100 to thresh the grain attached to the ear, and a traveling device ( 100), a driver's seat 400 installed on the upper part of the threshing device 200 for operation, a grain tank 500 in which the grain threshed by the threshing device 100 is stored, and one side of the threshing device 200. It includes a harvesting device (300) that is installed to cut the ears of crops and supply them to the threshing device (200).

And, as shown in Figure 2, the above-mentioned threshing device 200 is provided with a case 210 and a plurality of threshing equipment 225 on the outer peripheral surface and is supplied to the case 210 by the reaping device 300. A threshing bin 220 rotatably installed in the case 210 to thresh the grain from the ear, a water net 230 provided at the lower part of the threshing bin 220 so that the threshed grains are discharged to the bottom, and vibration. A sorting plate 240 installed at the lower part of the water net 230 to separate grains and debris, a blowing fan 250 for blowing air to the water net 230 and the sorting plate 240, and a rear threshing bin. A conveyor 260 that discharges the stems of crops that have been threshed, a first grain recovery unit 270 that transfers the selected grains to the grain tank 500, and grains mixed with debris into the threshing bin 220. It includes a second grain recovery unit 280 for retransfer.

In a conventional combine configured as described above, the ears of crops cut by the reaping device are introduced into the lower part of the rotating threshing bin and are threshed by threshing, and the threshed grains are passed through a water net provided at the bottom of the threshing bin to a sorting plate. and the grain stalks are discharged to the outside through a conveyor. Then, the grains and debris supplied to the sorting plate are sorted by the vibration of the sorting plate and the wind power supplied from the blower, and the grains fall into the first grain collection unit and are then transferred to the grain tank by the vertical conveyor of the first grain recovery unit for storage. The debris is blown backwards by the wind and discharged. At this time, some grains and ungrained ear parts included in the crumbs fall into the second grain recovery unit and are then re-transferred to the threshing bin by the conveyor of the second grain recovery unit to undergo a secondary threshing operation.

However, since the transfer speed and threshing type within the threshing bin vary depending on the type of crop, it is necessary to vary the feed arrangement depending on the type of crop and harvest speed. However, when using multiple threshing bins with different arrangements depending on the type and harvesting speed of the crop to be harvested, not only is a large preparation cost required, but there is also an unavoidable problem of time and cost loss due to replacement of threshing bins. .

The present invention was developed to solve the problems of the prior art as described above. The variable feed threshing bin for a combine of the present invention allows the feed arrangement to be changed depending on the type and harvest speed of the crop to be harvested. The task is to minimize threshing loss by ensuring equal hitting without any unhitted parts.

In addition, the task is to minimize threshing loss by dividing it into a pre-processing section where primary threshing is performed and a post-processing section where secondary threshing is performed, and by varying the delay angle between the teeth of the pre-processing section and the post-processing section.

The deformable threshing bin for a combine of the present invention for achieving the above object includes a plurality of pretreatment processing members for which a plurality of processing gears are installed at regular intervals on the outer peripheral surface to perform primary threshing; A plurality of post-processing members are installed on the outer peripheral surface at regular intervals to perform secondary threshing; A plurality of gap passages are formed in a cylindrical shape with a certain width and are respectively disposed between each preparation member; A rotating shaft installed to penetrate the center of each preparation member; A plurality of spacing maintainers inserted into the rotating shaft so that each preparation member maintains a certain spacing; It includes a fixing member fastened to the end of the rotating shaft so that each placement member that passes the gap remains in close contact with it.

In addition, the teeth of the pre-treatment preparation member and the post-treatment preparation member are each formed along the circumferential direction, and the spacing angle between teeth of the pre-treatment preparation member is characterized by being larger than the spacing angle between preparation teeth of the post-treatment preparation member.

In addition, a plurality of pre-treatment preparation members and a plurality of post-treatment preparation members form a pre-treatment unit and a post-treatment unit, respectively. However, the number of pre-treatment preparation members is greater than the number of post-treatment preparation members, and the entire pre-treatment preparation part has the same treatment interval. The pre-treatment preparation members are arranged to have a delay angle, and the post-treatment preparation members are arranged so that the entire post-treatment unit has the same delay angle between preparation parts.

Additionally, the delay angle between teeth in the preprocessing unit and the delay angle between teeth in the postprocessing unit may be different from each other.

In addition, the pre-treatment preparation member and the post-treatment preparation member may have fine-sized sawtooth portions formed on their sides to improve adhesion through the gap and enable fine adjustment of the rotation angle.

In addition, the pre-treatment preparation member and the post-treatment preparation member may be formed by each preparation being formed on the outside of a disk having a hole in the center into which the rotation axis is inserted.

In addition, the pre-treatment preparation member and the post-treatment preparation member may include a boss portion having a hole in the center into which the rotating shaft is inserted, a circular ring with a provision tooth formed on the outside, and a plurality of ribs connecting the boss portion and the circular ring. .

Additionally, the circular ring is formed so that the portion where the ribs are connected and the portion where the teeth are formed do not interfere with each other.

The deformable threshing bin for the combine of the present invention has a plurality of pre-treatment processing members and a plurality of post-treatment processing members, each spaced apart by a gap passage and a gap maintenance member, and each rotatable independently on a rotating shaft, so that the harvesting material to be harvested By optimizing the feed arrangement by changing it according to the type of crop and harvesting speed, there is an effect of minimizing threshing loss by preventing unhit parts from occurring and achieving equal striking.

In addition, by varying the number of pre-treatment preparation members for primary threshing and post-treatment preparation members for secondary threshing, the hitting delay time and hitting delay distance can be minimized, and the hitting delay length can be shortened to minimize non-threshing.

In addition, the effect of primary threshing and secondary threshing can be maximized by independently adjusting the delay angle between the pre-treatment unit consisting of a plurality of pre-treatment treatment members and the post-treatment unit consisting of a plurality of post-treatment treatment members.

In addition, as fine sawtooth parts are formed on the sides of the pre-treatment preparation member and the post-treatment preparation member, adhesion through the gap is increased and fine angle adjustment is possible.

In addition, the manufacturing cost can be reduced by forming the pre-treatment preparation member and the post-treatment preparation member in a disk shape, or the weight can be reduced by forming them in a rib shape.

In addition, when the pre-treatment preparation member and the post-treatment preparation member are configured in a rib shape, durability is improved by preventing interference between the part where the teeth are formed and the part where the ribs are connected.

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

The terms used in the present invention are terms defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator, so the definitions of these terms are defined in accordance with the technical details of the present invention. It should be interpreted as a concept.

As shown in Figures 3 to 7, the deformable threshing bin for a combine according to the present invention includes a plurality of pretreatment processing members 11 in which a plurality of processing gears 11' are installed at regular intervals to perform primary threshing, and ; A plurality of post-processing members 12, in which a plurality of processing devices 12' are installed on the outer peripheral surface at regular intervals to perform secondary threshing; A plurality of spacers (13) formed in a cylindrical shape with a certain width and disposed between each preparation member; A rotating shaft 14 installed to penetrate the center of each preparation member; A plurality of space maintaining members 16 provided to be inserted into the rotating shaft 14 so that each preparation member maintains a certain distance between them; It includes a fixing member 15 fastened to the end of the rotating shaft 14 to maintain the spacer 13 and each of the placement members 11 and 12 in close contact.

Here, the pre-treatment preparation member 11 has four preparation teeth 11' arranged at 90-degree intervals along the circumferential direction, and the post-treatment preparation member 12 has six preparation teeth 12' arranged at 60-degree intervals along the circumferential direction. It is arranged at intervals. Accordingly, the pre-treatment preparation member 11 performs primary threshing while minimizing the striking delay time and striking delay length using four preparation teeth 11', and the post-treatment preparation member 12 uses six preparation teeth By shortening the blow overlap length using (12'), non-threshing during secondary threshing is minimized.

Additionally, 18 pre-treatment treatment members 11 constitute the pre-treatment section (A), and 9 post-treatment application members 12 constitute the post-treatment section (B). At this time, it is desirable to set the delay angle between the teeth of the preprocessing unit (A) and the delay angle between the teeth of the postprocessing unit (B) to be different from each other, and the delay angle between the teeth of the preprocessing unit (A) should be as small as possible to determine the striking delay time and striking delay. It is more desirable to minimize the length and make the delay angle between the teeth of the post-processing unit (B) as large as possible to shorten the impact overlap length. For example, the delay angle between teeth in the pre-treatment unit (A) is set to 0 to 30 degrees, and the delay angle between teeth in the post-processing unit (B) is set to 55 to 80 degrees.

In addition, the pre-treatment preparation member 11 and the post-treatment preparation member 12 may be provided with an angle display unit indicating the rotation angle, and the side thereof may improve adhesion to the spacer 13 and allow fine adjustment of the rotation angle. A fine-sized sawtooth part may be formed. Accordingly, it is possible to adjust the delay angle between preparations while checking the rotation angle of the pre-treatment preparation member 11 and the post-treatment preparation member 12 through the angle display unit, and the adhesion with the spacer 13 is maintained using the sawtooth-shaped part. It improves and prevents relative rotation from occurring, and allows for fine angle adjustment.

In addition, since the delay angle between the treatment parts of the pre-processing unit (A) and the post-processing unit (B) may vary depending on the width of the spacer 13, the spacer 13 may be 32 mm, 36 mm, 40 mm, 49 mm, etc. It can be formed in various widths. Accordingly, when adjusting the delay angle between the pre-treatment unit (A) and the post-treatment unit (B), the rotation angles of the pre-treatment preparation member 11 and the post-treatment preparation member 12 are adjusted, and at the same time, the spacer 13 is adjusted. By changing the width, it is possible to obtain more diverse delay angles between teeth.

And, as shown in (a) of FIG. 6, the pre-treatment preparation member 11 can be formed by four preparation teeth 11' formed on the outside of the disk 11a with a hole in the center into which the rotation axis 14 is inserted. , as shown in (b) of FIG. 6, a boss portion 11b having a hole in the center into which the rotation axis 14 is inserted, a circular ring 11d having a preparation tooth 11' formed on the outside, and a boss portion 11b. It may include a plurality of ribs (11c) connecting the circular ring (11d). At this time, it is natural that the circular ring 11d should be formed so that the portion where the ribs 11c are connected, the portion where the preparation teeth 11' are formed, and the portion where the circular ring 11d is welded do not interfere with each other.

In addition, the post-treatment preparation member 12 can be formed by forming six preparation teeth 12' on the outside of the disk 12a, which has a hole in the center into which the rotation axis 14 is inserted, as shown in (a) of Figure 7. 7(b), a boss portion 12b having a hole in the center into which the rotation shaft 14 is inserted, a circular ring 12d having a preparation tooth 12' formed on the outside, and a boss portion 12b ) and a plurality of ribs (12c) connecting the circular ring (12d). At this time, it is natural that the circular ring 12d should be formed so that the portion where the ribs 12c are connected, the portion where the preparation teeth 12' are formed, and the portion where the circular ring 12d is welded do not interfere with each other.

If the pre-treatment preparation member 11 and the post-treatment preparation member 12 are formed in a disk shape, there is an advantage in that the manufacturing cost is lowered, but there is a disadvantage in that the weight increases. On the other hand, when the pre-treatment preparation member and the post-treatment preparation member are configured in a rib shape, there is a disadvantage in that the weight is reduced but the manufacturing cost increases. Therefore, an appropriate method is selected and used considering weight and manufacturing cost.

The operation of the rapidly deformable threshing bin for a combine of the present invention configured as described above will be described as follows.

The process of inserting the post-treatment preparation member 12 into the rotary shaft 14 and rotatably coupling it, coupling the spacer 16 to the rotary shaft 14, and coupling the spacer 13 to the outside thereof. Repeatedly, the central parts of the post-treatment preparation members 12 are spaced apart from each other by the space maintaining member 16 and the outer portions of the post-treatment preparation members 12 are spaced apart from each other by the spacer 13, so that approximately 9 post-treatment preparation members 12 are spaced apart from each other by the spacer 16. A post-processing section (B) consisting of a processing member (12) is formed.

Next, the process of inserting the pretreatment treatment member 11 into the rotating shaft 14 to rotatably couple it, coupling the spacer 16 to the rotating shaft 14, and coupling the spacer 13 to the outside thereof. By repeating this, the central portions of the pre-treatment treatment members 11 are spaced apart from each other by the spacer 16 and the outer portions of the pre-treatment treatment members 11 are spaced apart from each other by the spacer 13, so that approximately 18 pre-treatment treatment members 11 are spaced apart from each other by the spacer 16. A pretreatment unit (A) consisting of a member (11) is formed. And when the configuration of the pre-processing unit (A) is completed, the fixing member 15 is fastened to the tip of the rotating shaft 14 so that each of the fixing members 11 and 12, the spacer 13, and the spacer 16 are connected to each other. Fix them so that they are tightly attached to each other and do not rotate.

Accordingly, the rotating shaft 14, 9 post-treatment preparation members 12, 18 pre-treatment preparation members 11, 26 spacers 16 and spacers 13, and fixing members 15. The threshing bin is completed.

Afterwards, when the crop to be harvested is determined, the crop arrangement is optimized by adjusting the delay angle between the crops of the pre-processing unit (A) and the post-processing unit (B) according to the type and harvesting speed of the crop. That is, by loosening the fixing member 15 to some extent so that the pre-treatment preparation member 11 and the post-treatment preparation member 12 can be rotated, the pre-treatment preparation member 11 and the post-treatment preparation member 12 are By rotating each tooth, the delay angle between teeth is changed.

Specifically, each pre-treatment preparation member 11 is rotated independently so that the delay angle between preparations in the entire pre-treatment unit (A) is maintained constant, and each post-treatment preparation member 11 is rotated so that the delay angle between treatment preparations in the entire post-treatment unit (B) is maintained constant. The processing member 12 is rotated independently. At this time, the delay angle between the teeth of the pre-processing unit (A) is adjusted within the range of 0 to 30 degrees because the smaller the delay angle between the teeth of the pre-processing unit (A), the shorter the hitting delay time and the shorter the striking delay distance, preventing non-hits from occurring, and the delay between the teeth of the post-processing unit (B) is adjusted within the range of 0 to 30 degrees. The larger the angle, the shorter the overlapping length of the blow, which results in repeated strikes, so adjust it within the range of 55 to 80 degrees.

Once the setting of the delay angle between the teeth of the pre-treatment unit (A) and the delay angle between the teeth of the post-processing unit (B) is completed through the above process, the fixing member 15 is fastened to the rotating shaft 14 to attach each preparation member 11. (12), the space maintenance device (16), and the spacer (13) are kept in close contact with each other to prevent the preparation arrangement from being disturbed.

In this way, when the arrangement of the threshing bin is changed depending on the type and harvesting speed of the crop to be harvested, the unthreshed material is removed through primary threshing in the pre-processing unit (A) and secondary threshing in the post-processing unit (B). It is possible to minimize parts and reduce threshing loss.

The above description is an illustrative description of the present invention, and the embodiments published in the specification are not intended to limit the technical idea of the present invention, but are for illustrative purposes, so those skilled in the art will be familiar with the present invention. Various modifications and variations will be possible without departing from the technical idea of . Therefore, the scope of protection of the present invention should be interpreted based on the matters stated in the claims, and technical matters within the equivalent scope thereof should also be interpreted as being included in the scope of rights of the present invention.
