Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bearing adjustment base device for a grain lifting machine, and is devised to reduce construction costs through a simple structure and to increase the strength of the box body.

In general, grain lifting machines made of metal plates have the defect that the strength of the box body is insufficient when the thickness of the plate is thinned to reduce component costs, and there is also a bearing that moves to adjust the tension of the internal tension belt. If a separate base for supporting the moving threaded rod is provided and attached to the box, the structure becomes complicated, and if the box is thin, the side walls tend to bend.

The present proposal will be explained with reference to the drawings.

Bearing adjustment bases 9 and 10 protrude outward from respective through holes 7 and 8 provided in both side walls 5° 6 near the bearings 3 and 4 of the grain lifting machine box body 2 on which the internal pulley 1 is mounted. This is a base device for bearing adjustment in which the width of the fitting part 12 fitted into the gap between the side walls 5 and 6 of the metal strip plate 11 integrally provided with is wider than the width of the through holes 7 and 8.

Reference numerals 13 and 14 are threaded rods for adjusting bearing movement that connect the bearings 3 and 4 to the respective bases 9 and 10.

The present invention can be easily assembled by simply penetrating the integral metal strip 11 through the through holes 7 and 8 provided in the side walls 5 and 6 themselves.

Therefore, the wide fitting portions 12 fitted into the internal spacing between the side walls 5 and 6 reinforce the side walls 5 and 6 against lateral pressure, making the box body 2 more robust and preventing the metal strip 11 from moving laterally. As a result, the positions of the bases 9 and 10 can be stably fixed.

In addition, the pressing force generated on the base 9° 10 to which the screw rods 13 and 14 for movement adjustment that push the bearings 3 and 4 are screwed is
Since the pressure is dispersedly transmitted to both side walls 5 and 6, the withstand pressure of both side walls 5 and 6 acts as a resultant force, and as in the conventional case, the base is pushed by the threaded rod and the side wall surface is distorted inward and outward. Such defects are eliminated, and the plate material of the entire box body can be made as thin as possible, so that the weight of the grain lifting machine can be reduced and the construction cost can be reasonably reduced.

In this case, metal plates 15 and 16 for reinforcing the side walls 5 and 6 are inserted between the wide fitting part 12 of the metal band plate 11 fitted into the box body 2 and the side walls 5 and 6. By welding to the side walls 5 and 6, the strength of the box body 2 can be further increased.

Further, in order to insert the metal strip into the both side walls, the both side walls 5 and 6 are opened slightly, and the metal strip is inserted into the through holes 7 and 8 at the same time to complete the assembly.

In this case, by installing a metal strip with bases at both ends through the walls on both sides, the pressure resistance of the grain lifting machine box body can be increased and it can be made more robust, and the side wall members can be made thinner to reduce construction cost. It is effective in that it saves money.
