Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, specifically to a speed reducer fixing device for connecting wooden disc screens. Background Technology

[0002] The chemical pulping process includes wood preparation, cooking, washing, bleaching, and causticizing. Wood preparation involves cutting long, thick timber into smaller pieces and removing impurities before pulping; in other words, processing the logs and screening out the wood chips that meet the requirements. During the screening process, a speed reducer drives a disc screen, where multiple rollers rotate in the same direction, maintaining a certain distance between them. The material moves above the rollers, with smaller wood chips falling between the rollers and larger wood chips flowing out of the disc screen with the rollers.

[0003] Currently, the main shaft of the wood disc screen reducer used is connected to the disc screen in a sleeve-mounted installation manner, such as... Figure 1 This includes the disc screen, bearings, reducer, main shaft, motor, I-beam, and soft pads. During operation, the clearance between the main shaft and the reducer sleeve is too large. In addition, the reducer is softly fixed, resulting in large shaking after opening. After prolonged use, the main shaft wears out, and the reducer does not reach its service life, posing a potential equipment hazard.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] The main shaft of the existing log tray screen wears down with use, requiring repair or cutting at the worn areas. This results in the repaired main shaft being unable to connect stably with the reducer output shaft, affecting the stability of the log tray screen during operation.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a speed reducer fixing device for connecting a log tray screen. This device solves the problem that in traditional technologies, the main shaft of the log tray screen wears down with use, requiring repair or cutting at the worn area. This results in the repaired main shaft being unable to stably connect with the speed reducer output shaft, affecting the stability of the log tray screen during operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A speed reducer fixing device for connecting a wood disc screen includes a fixed base, an angle adjusting seat that swings on the fixed base, an orientation adjusting seat that rotates on the angle adjusting seat, a spacing adjusting seat that slides horizontally on the orientation adjusting seat, a speed reducer body that is fixed on the spacing adjusting seat, and the output shaft of the speed reducer body that is connected to the main shaft of the wood disc screen via a coupling.

[0010] As an optimized solution, one end of the angle adjustment seat is hinged to the fixed seat via a hinge joint, and the other end of the angle adjustment seat adjusts the distance between it and the fixed seat via a telescopic structure.

[0011] As an optimized solution, the telescopic structure includes a threaded cylinder hinged to the angle adjustment seat via an upper hinge seat, a screw threadedly connected to the threaded cylinder, a turntable fixed to the lower end of the screw, and the lower end of the turntable hinged to the fixed seat via a lower hinge seat.

[0012] As an optimized solution, a locking nut is also threaded onto the screw, with the upper end of the locking nut abutting against the lower end of the threaded cylinder.

[0013] As an optimized solution, a support plate is horizontally fixed to the angle adjustment seat, and a rotating disk is mounted on the support plate for rotation. The orientation adjustment seat is fixed to the upper end of the rotating disk.

[0014] As an optimized solution, the rotating disk has a constraint groove that matches the support disk, and is rotatably mounted on the support disk through the constraint groove.

[0015] As an optimized solution, an angle fixing knob is threaded onto the outer wall of the rotating disk, and the end of the angle fixing knob abuts against the outer wall of the support disk.

[0016] As an optimized solution, the outer wall of the support plate is provided with several angle positioning grooves, and the end of the angle fixing knob abuts against the positioning grooves.

[0017] As an optimized solution, two guide rails are fixedly connected side by side to the upper surface of the orientation adjustment seat, and two slide blocks are slidably arranged side by side on each guide rail. The lower surface of the spacing adjustment seat is fixedly connected to the upper end of the slide block.

[0018] As an optimized solution, a lower fixing plate is vertically fixed to the orientation adjustment seat, and an upper fixing plate arranged parallel to the lower fixing plate is fixed to the lower surface of the spacing adjustment seat. A rotating shaft is horizontally rotatably mounted on the lower fixing plate, and the rotating shaft is provided with a threaded section, which is threadedly connected to the upper fixing plate.

[0019] As an optimized solution, a throttle handle is fixedly connected to the other end of the shaft.

[0028] One end of the angle adjustment seat 2 is hinged to the fixed seat 1 via the hinge seat 3, and the other end of the angle adjustment seat 2 is adjusted to maintain the distance between it and the fixed seat 1 via the telescopic structure 4.

[0029] The telescopic structure 4 includes a threaded cylinder 22 hinged to the angle adjustment seat 2 by an upper hinge seat 20. The threaded cylinder 22 is internally threaded with a screw 23. The lower end of the screw 23 is fixedly connected to a turntable 24. The lower end of the turntable 24 is hinged to the fixed seat 1 by a lower hinge seat 21.

[0030] A locking nut is also threaded onto the screw 23. The upper end of the locking nut abuts against the lower end of the threaded cylinder 22. The locking nut can lock the current position of the screw 23 to prevent it from loosening.

[0031] A support plate 5 is horizontally fixed to the angle adjustment seat 2. A rotating plate 6 is mounted on the support plate 5 for rotation. The angle adjustment seat 9 is fixed to the upper end of the rotating plate 6.

[0032] The rotating disk 6 has a constraint groove that matches the support disk 5, and is rotatably mounted on the support disk 5 through the constraint groove.

[0033] An angle fixing knob 8 is threadedly connected to the outer wall of the rotating disk 6. The end of the angle fixing knob 8 abuts against the outer wall of the support disk 5. The orientation of the orientation adjustment seat 9 can be fixed by stirring the fixing knob.

[0034] The outer wall of the support plate 5 is provided with several angle positioning grooves 7, and the end of the angle fixing knob 8 abuts against the positioning groove.

[0035] Two guide rails 14 are fixedly connected side by side to the upper surface of the adjustment seat 9. Two slide blocks 15 are slidably mounted side by side on each guide rail 14. The lower surface of the spacing adjustment seat 10 is fixedly connected to the upper end of the slide block 15.

[0036] A lower fixing plate 16 is vertically fixed to the adjusting seat 9.
