Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to bearing housing and seed shell separator. Background Technology

[0002] In the processing of camellia seeds, the camellia seed shell separator is one of the core pieces of equipment, and its separation effect directly affects the subsequent processing quality of the camellia seeds.

[0003] Currently, the widely used camellia seed shell separators on the market mainly adopt the principle of roller crushing, that is, through the combination of multiple toothed rollers and smooth rollers (for example, publication number CN114271510 B, the roller assembly 312 includes large rollers and small rollers arranged at intervals along the length of the frame 10, the large rollers are toothed rollers and the small rollers are smooth rollers), the squeezing and pulling action between the rollers causes the shells to fall off, while pushing the camellia seeds forward. This technology has high separation efficiency and clean shelling, and has good market acceptance.

[0004] However, existing double-roller camellia seed shell separators have a large number of rollers, making disassembly and assembly inconvenient and cumbersome. The bearings at both ends of each roller set need to be hammered into the bearing holes of the bearing seat, which can easily lead to bearing damage. Furthermore, the coaxiality of the bearing positions is difficult to control precisely, affecting the stability of the equipment operation. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a bearing housing and a seed shell separator.

[0006] This utility model provides a bearing housing, including a positioning cover and a positioning seat. The positioning cover is connected to the positioning seat by bolts. The positioning cover includes a left cover, a middle cover and a right cover. The left cover and the right cover are symmetrical. An odd number of middle covers are provided between the left cover and the right cover.

[0007] The positioning seat includes a left positioning seat and a right positioning seat, and the left positioning seat and the right positioning seat are symmetrical structures;

[0008] The positioning cover and the positioning seat are evenly distributed along the length direction with a first bearing mounting groove for inserting the first bearing and a second bearing mounting groove for inserting the second bearing. The center of the second bearing mounting groove is higher than the center of the first bearing mounting groove.

[0009] Furthermore, the outer side of the upper surface of the right positioning seat is evenly distributed with a first lower semi-circular positioning groove along the length direction, and the inner side of the upper surface of the right positioning seat is evenly distributed with a second lower semi-circular positioning groove and an upper open U-shaped groove in an alternating manner along the length direction. The second lower semi-circular positioning groove and the first lower semi-circular positioning groove are staggered in the length direction. The center of the second lower semi-circular positioning groove is higher than the center of the first lower semi-circular positioning groove, and the bottom wall of the first lower semi-circular positioning groove is lower than the bottom wall of the upper open U-shaped groove.

[0010] The bottom inner side of the right cover is evenly distributed with second upper semi-circular positioning grooves along the length direction. The bottom outer side of the right cover is staggered with first upper semi-circular positioning grooves and lower open U-shaped grooves along the length direction. The first upper semi-circular positioning grooves and second upper semi-circular positioning grooves are staggered along the length direction. The center of the second upper semi-circular positioning groove is higher than the center of the first upper semi-circular positioning groove. The bottom wall of the second upper semi-circular positioning groove is higher than the bottom wall of the lower open U-shaped groove.

[0012] Furthermore, the second upper semi-circular positioning groove and the lower open U-shaped groove at one end of the right cover are semi-groove structures;

[0013] The difference between the middle cover and the right cover is that the second upper semi-circular positioning groove and the lower open U-shaped groove at both ends of the middle cover are both semi-groove structures.

[0014] Furthermore, a first lower semi-circular positioning ring is provided at the outer opening of the first lower semi-circular positioning groove, and a first upper semi-circular positioning ring is provided at the outer opening of the first upper semi-circular positioning groove. The first lower semi-circular positioning ring and the first upper semi-circular positioning ring cooperate to form the outer positioning ring of the first bearing.

[0015] The inner opening of the second lower semi-circular positioning groove is provided with a second lower semi-circular positioning ring, and the inner opening of the second upper semi-circular positioning groove is provided with a second upper semi-circular positioning ring. The second lower semi-circular positioning ring and the second upper semi-circular positioning ring cooperate to form the inner positioning ring of the second bearing.

[0016] This utility model also provides a seed shell separator, including the aforementioned bearing housing. Beneficial effects:

[0017] This invention avoids bearing damage caused by hammering the bearing into the bearing hole, thus improving the bearing's service life. Both the positioning seat and the positioning cover adopt a split structure, which can meet the simultaneous installation of multiple shaft rollers. The installation is simple and quick, and the positioning is accurate. During maintenance, only the corresponding cover needs to be removed and the corresponding shaft roller replaced, which reduces maintenance costs. Attached Figure Description
