When the viscosity of two types of lubricating oil needs to be compared, firstly, an operator pours two different types of lubricating oil into the engine oil boxes 5 on the left side and the right side respectively, then the driving mechanism 30 is started, the driving mechanism 30 drives the second gear 29 to rotate, the second gear 29 rotates to drive the second rack 27 to move upwards, the second rack 27 moves upwards to drive the guide rod 26 to move upwards, the guide rod 26 moves upwards to drive the engine oil boxes 5 to rotate, after the engine oil boxes 5 rotate for a certain angle, the operator pulls the vertical rod 8 to move upwards, the vertical rod 8 moves upwards to drive the plug block 7 to move upwards, the plug block 7 moves upwards to draw out the discharge hole 6, the lubricating oil in the engine oil boxes 5 flows onto the inclined plate 9 through the discharge hole 6, when enough lubricating oil flows out from the engine oil boxes 5, the vertical rod 8 is pushed downwards to enable the plug block 7 to plug the discharge hole 6 again, then the driving mechanism 30 is started to drive, the lower the viscosity of the lubricating oil, the faster the flow rate of the lubricating oil on the inclined plate 9 is, the higher the viscosity is, the slower the flow rate is, the lubricating oil flows onto the blades 12 from the inclined plate 9, the lubricating oil flows onto the blades 12 to drive the rotating disc 11 to rotate, the rotating disc 11 rotates to drive the first belt pulley 13 to rotate, the first belt pulley 13 rotates to drive the second belt pulley 16 to rotate through the first flat belt 17, the second belt pulley 16 rotates to drive the first gear 18 to rotate, the first gear 18 rotates to drive the first rack 21 to move upwards, the lubricating oil finally falls into the collection frame 15, an operator measures the upward movement distance of the first racks 21 on two sides at the moment, the higher the upward movement of the first racks 21 on two sides is, the lower the viscosity of the lubricating oil is indicated, and vice versa, so that the viscosity comparison result. Can be more swift to the contrast of the viscosity of two kinds of lubricating oil.
The operating personnel starts left motor 302 and rotates clockwise, start right motor 302 and rotate anticlockwise, motor 302 output shaft rotates and drives third belt pulley 303 and rotate, third belt pulley 303 drives fourth belt pulley 304 through second flat belt 305 and rotates, fourth belt pulley 304 rotates and drives second gear 29 and rotate, second gear 29 rotates and drives second rack 27 and upwards removes, when needs reset oil box 5, start left motor 302 and rotate anticlockwise, start right motor 302 and rotate clockwise, second rack 27 moves downwards, when standby oil box 5 resets completely, close motor 302.
When the engine oil box 5 rotates, the third gear 34 rotates through the arc-shaped rack 32, the third gear 34 rotates to drive the reel 35 to rotate, the reel 35 rotates to wind the pull wire 36, the pull wire 36 is wound to drive the vertical rod 8 to move upwards, the vertical rod 8 moves upwards to drive the plug 7 to move upwards, the spring 37 is compressed, the plug 7 moves upwards to open the discharge hole 6, and the lubricating oil flows out through the discharge hole 6. So, do not need operating personnel to stimulate montant 8 upwards with the hand, improved efficiency, reduced the operation difficulty, when oil box 5 resets, third gear 34 is through arc rack 32 antiport, and reel 35 emits and acts as go-between 36, and montant 8 resets downwards under the effect of spring 37, and discharge gate 6 is plugged up to chock 7.
The first rack 21 moves upwards to drive the pointer 39 to move upwards, and when the first rack 21 stops moving upwards, an operator can know the comparison result of the viscosities of the lubricating oil on the two sides by looking at the position where the pointer 39 stays on the scale 38. So, operating personnel need not to use the dipperstick to measure the comparison to first rack 21, makes the expression of contrast result more directly perceived, clear. And the measuring time is reduced, and the contrast efficiency is improved.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
