[0037] See Figure 1 and Figure 2 This utility model discloses a horizontal moving mechanism for a scraper bar driven motor, comprising:
[0038] The system includes a main drive bracket 2, a sliding sealing plate 23, a drive assembly, a reducer base 10, a motor 14, and a reducer 13. The main drive bracket 2 is fixed on the extraction tank wall plate 28, and one side of it has a horizontal groove extending in the horizontal direction. One side of the sliding sealing plate 23 has a sliding part, which is slidably embedded in the horizontal groove. The drive assembly is connected to the sliding sealing plate 23 and can drive the sliding sealing plate 23 to move horizontally. The reducer base 10 is fixed on the sliding sealing plate 23, and the motor 14 and the reducer 13 are connected to each other and fixedly connected to the reducer base 10.
[0039] The scraper bar drive motor horizontal movement mechanism provided by this utility model drives the sliding sealing plate 23 to move horizontally through the cooperation of the lead screw and lead nut, thereby adjusting the position of the motor 14 and the reducer 13 as a whole, thus reducing the eccentricity between the scraper bar 27 and the reducer output shaft. This design effectively avoids the problem of frequent damage to the universal coupling due to excessive eccentricity, and extends the service life of the equipment.
[0040] Specifically:
[0041] The main drive bracket 2 is bolted to the extraction tank wall plate 28, and a T-shaped transverse groove extending horizontally is machined on one side of it. A sliding part is provided on one side of the sliding sealing plate 23, which slidably embeds into the T-shaped groove of the main drive bracket 2. A first annular sealing gasket 3 is provided between the main drive bracket 2 and the extraction tank wall plate 28, achieving a static seal by bolt tightening. A closed O-ring sealing strip 6 is provided between the sliding sealing plate 23 and the sliding surface of the main drive bracket 2 to prevent dichloromethane gas leakage.
[0042] The drive assembly includes a trapezoidal threaded lead screw 15 and a trapezoidal threaded nut 22. A bearing housing 16 is welded to the extraction tank wall plate 28. The lead screw is mounted within the bearing housing 16 via a second bearing 17 and locked in place by a precision lock nut 19. A bearing cap 18 is bolted to the bearing housing 16, restricting the axial displacement of the second bearing 17. The trapezoidal threaded nut 22 is bolted to a sliding sealing plate 23 and engages with the lead screw. A crank handle 20 is mounted at one end of the lead screw. When the lead screw is manually rotated, the trapezoidal threaded nut 22 drives the sliding sealing plate 23 to move horizontally along the T-slot. The trapezoidal thread provides stable drive, adapting to large stroke adjustment requirements.
[0043] The reducer base 10 is bolted to the main drive support 9, which in turn is bolted to the sliding sealing plate 23.

[0044] A fixing plate 24 is bolted to both the upper and lower sides of the main drive bracket 2. The free end of the fixing plate 24 extends above the side surface of the sliding sealing plate 23 facing away from the main drive bracket 2, forming a limiting stop. A scale 25, made of steel, is provided on the fixing plate 24, and corresponding indicator marks are provided on the sliding sealing plate 23. By observing the corresponding positions of the indicator marks and the scale, the operator can intuitively read the horizontal movement value of the sliding sealing plate 23, improving adjustment accuracy and operating efficiency.

[0046] Dynamic sealing: The lip seal 4 rotates with the main drive shaft 11 to form a continuous sealing surface, preventing gas leakage.
[0047] In summary, the horizontal moving mechanism of the scraper bar drive motor provided by this utility model has the following advantages:
[0048] Beneficial effects:
[0049] Horizontal adjustment function: The trapezoidal threaded screw 15 and trapezoidal threaded nut 22 cooperate to achieve precise drive. The sliding sealing plate 23 drives the motor 14 and reducer 13 to move as a whole, reducing the eccentricity between the rod 27 and the reducer output shaft in real time, and avoiding frequent damage to the universal coupling 1.
[0050] Multiple sealing design: O-ring seal 6 solves the problem of sliding surface leakage; first annular sealing gasket 3 and second annular sealing gasket 8 achieve static sealing; lip seal 4 ensures rotational sealing and completely prevents dichloromethane leakage.
