Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a bearing for a threshing drum of a millet combine harvester. Background Art

[0002] The millet combine harvester is a combine harvesting equipment designed for crops such as millet. It can complete multiple operations such as harvesting, threshing, cleaning, and receiving at one time, greatly improving agricultural production efficiency. Therefore, by using the threshing drum of the millet combine harvester to support and rotate and guide, it is ensured that the threshing drum rotates quickly to complete the millet threshing. However, in the existing technology, when the bearing supports the threshing drum of the millet combine harvester, since millet particles may splash during the threshing process, the diameter of millet particles is small, which will cause some millet particles to enter the bearing, thereby affecting the normal rotation of the bearing and the efficiency of millet threshing. Summary of the Invention

[0003] The disclosed embodiments relate to bearings for a threshing drum of a millet combine harvester, so as to solve the problem in the prior art that when the bearings support the threshing drum of the millet combine harvester, millet particles may splash during the threshing process. Since the diameter of millet particles is relatively small, some millet particles may enter the bearings, thereby affecting the normal rotation of the bearings and the efficiency of millet threshing.

[0004] According to a first aspect of the present disclosure, a bearing for a threshing drum of a millet combine harvester is provided, specifically comprising: an outer ring and an inner ring, wherein the outer ring is an annular structure, and the inner side of the outer ring is an arc-shaped structure, and the inner ring is arranged on the inner side of the outer ring; an injection hole is provided on the outer side of the outer ring, and a circulation groove is provided on the inside of the outer ring; the circulation groove is an annular structure, and the side surface of the circulation groove is connected to the inner end of the injection hole; positioning storage tanks are provided on the top and bottom of the outer side of the outer ring.

[0005] Furthermore, a groove is provided on the outer side of the inner ring, the groove is an arc-shaped structure, and a steel ball is installed between the outer side of the inner ring and the inner side of the outer ring for rolling; a buffer stabilizer is provided on the inner side of the inner ring, wherein the buffer stabilizer is an annular structure of elastic material, and slots are provided on the top and bottom of the inner ring.

[0006] Furthermore, a diversion groove, a guide groove and an oil outlet hole are provided inside the outer ring; and the side end of the diversion groove is connected to the side surface of the circulation groove.

[0007] Furthermore, the guide groove is an annular structure, and the side of the guide groove is connected to the other side end of the diversion groove, and the side of the guide groove is also connected to the inner end of the oil outlet hole; the outer end of the oil outlet hole is on the inner side of the outer ring.

[0008] Furthermore, the top and bottom of the outer side of the outer ring are both provided with positioning grooves; the positioning grooves are connected to the side of the positioning storage tank; the top and bottom of the outer side of the inner ring are both provided with positioning slots, wherein the positioning slots are annular structures.

[0009] Furthermore, a sealing plate is slidably installed inside the positioning storage tank; the sealing plate is an arc-shaped plate structure, and the inner side of the sealing plate is slidably installed inside the positioning slot, and a guide plate is installed in the middle position of the outer side of the sealing plate; the top of the guide plate is an inclined structure, and the inner side of the guide plate is slidably installed inside the positioning slot through a spring.

[0010] The utility model provides a bearing for a threshing drum of a millet combine harvester, which has the following beneficial effects:

[0011] When the utility model is in use, the internal space of the bearing is sealed by using a sealing plate, thereby reducing the possibility of millet particles entering. When the bearing on the threshing drum of the millet combine harvester is in use, when the bearing is not installed on the shaft of the threshing drum, the sealing plate is located inside the positioning storage tank, which is convenient for lubricating the bearing. When the bearing is installed on the shaft, the outer side of the outer ring is subjected to pressure to push the guide plate to drive the sealing plate to seal the space between the outer ring and the inner ring, and seal the area where the steel ball moves, thereby reducing the possibility of millet particles entering during the millet threshing process, ensuring the smooth operation of the bearing, and improving the efficiency of millet threshing.

[0012] In addition, by using the oil outlet holes to evenly lubricate the steel balls, when the bearings on the threshing drum of the Xiaomi combine harvester are in use, the lubricating oil passes through the annular groove and the diversion groove to the interior of the upper and lower guide grooves. The guide groove is connected to multiple oil outlet holes, so that the lubricating oil flows out from the oil outlet holes in multiple directions to lubricate the steel balls, preventing the problem of uneven lubrication and severe wear of some steel balls, thereby increasing the service life of the steel balls.
