[0020] like Figure 1-4 As shown, the utility model provides a chain plate scraper blade installation structure, comprising a scraper 1, a scraper 2 is provided at the bottom of the scraper 1, a sealing groove 4 is opened on the side of the scraper 1 near the bottom, and a sealing block 3 is clamped on the inner wall of the sealing groove 4;

[0021] After the scraper 1 and the scraper 2 are slidably installed, the installation position is sealed using the sealing block 3 and the sealing groove 4;

[0022] The bottom of the scraper 1 is provided with a clamping mechanism for clamping with the scraper 2, and the middle of the scraper 1 is provided with a limiting mechanism.

[0023] In summary, compared with the problem that the bolts fixing the scraper 2 are easily corroded in the existing equipment, which makes it troublesome for the operator to disassemble and replace the scraper 2, the scraper 1 and scraper 2 are installed by a clamping mechanism, and then the installed scraper 1 and scraper 2 are reinforced by a limiting mechanism to avoid the scraper 1 and scraper 2 from falling off and separating due to shaking during use.

[0024] The clamping mechanism includes a T-slot 7 formed on the inner wall of the sealing groove 4, a T-bar 5 adapted to the sealing groove 7 is formed on the side of the sealing block 3 close to the T-slot 7, a chamfer 6 is formed on the top of the T-bar 5 away from the sealing groove 4, and a limiting mechanism is provided in the middle of the inner wall of the T-slot 7. The sealing groove 4 is clamped into the sealing block 3 by sliding the T-bar 5 on the scraper 2 into the T-slot 7 formed at the bottom of the scraper 1, and then the sealing groove 4 is clamped into the sealing block 3. The scraper 1 and the scraper 2 are stabilized by the cooperation of the chamfer 6 on the T-bar 5 and the limiting mechanism.

[0025] The limiting mechanism includes a movable groove 8 provided in the middle of the inner wall of the T-shaped groove 7, a limiting rod 9 is provided on the inner wall of the movable groove 8, a slot for the limiting rod 9 to be engaged is provided at the top of the T-shaped rod 5, and a rounded corner 10 is provided at the bottom of the limiting rod 9. When the T-shaped rod 5 is pushed, the chamfer 6 contacts the rounded corner 10 at the bottom of the limiting rod 9, so that the rounded corner 10 drives the limiting rod 9 to move upward in the movable groove 8. When the rounded corner 10 at the bottom of the limiting rod 9 moves into the slot provided at the top of the T-shaped rod 5, the limiting rod 9 and the rounded corner 10 are engaged into the slot at the top of the T-shaped rod 5, and the installation of the scraper 1 and the scraper 2 is completed at this time;

[0026] The limiting mechanism also includes a hexagonal slide bar 11 slidably connected to the limiting rod 9, a return spring 12 is sleeved on the outer contour of the hexagonal slide bar 11, a connecting rod 13 is fixedly connected to the top of the hexagonal slide bar 11, a fastening bolt 14 is fixedly connected to the top of the connecting rod 13, and a threaded groove for threaded connection of the fastening bolt 14 is opened near the inner wall of the top of the movable groove 8. When the limiting rod 9 moves upward, the return spring 12 on the outer contour of the hexagonal slide bar 11 is squeezed. When the limiting rod 9 moves to the slot on the T-bar 5, the elasticity generated by the squeezed return spring 12 causes the limiting rod 9 to move downward into the slot on the T-bar 5;

[0027] A cavity 16 is provided at the top of the limit rod 9, and a hexagonal stopper 18 is threadedly connected to the inner wall of the cavity 16 near the top. The inner wall of the hexagonal stopper 18 is slidably connected to the hexagonal slide rod 11, and the bottom of the hexagonal slide rod 11 is fixedly connected to a sliding block 17. When the limit rod 9 moves, the sliding block 17 at the bottom of the hexagonal slide rod 11 moves in the cavity 16 opened at the top of the limit rod 9, thereby making the sliding of the limit rod 9 smoother. After the hexagonal slide rod 11 is damaged, the operator takes out the limit rod 9, and then rotates the hexagonal slide rod 11 to drive the hexagonal stopper 18 threadedly connected to the inner wall of the limit rod 9 to rotate. After accommodating, the hexagonal slide rod 11 is removed, and the return spring 12 can be replaced at this time.

[0028] A sealing gasket 15 is provided on the inner wall of the thread groove, and the top of the sealing gasket 15 is sleeved with the fastening bolt 14. By sealing the connection between the thread groove and the fastening bolt 14 with the sealing gasket 15, the sealing effect is enhanced.

[0029] By sliding the T-bar 5 on the scraper 2 into the T-slot 7 opened at the bottom of the scraper 1, and utilizing the chamfer 6 on the T-bar 5 to cooperate with the rounded corner 10 at the bottom of the limit rod 9, the rounded corner 10 drives the limit rod 9 to move upward in the movable groove 8. When the limit rod 9 moves, the sliding block 17 at the bottom of the hexagonal slide rod 11 moves in the cavity 16 opened at the top of the limit rod 9. At the same time, the limit rod 9 is adjusted to the outer contour of the hexagonal slide rod 11 by the reset spring 12, and the elasticity generated by the squeezed reset spring 12 is utilized to make the limit rod 9 move downward into the slot on the T-bar 5. When the rounded corner 10 at the bottom of the limit rod 9 moves to the slot opened at the top of the T-bar 5, the limit rod 9 and the rounded corner 10 are engaged into the slot at the top of the T-bar 5. At this time, the installation of the scraper 1 and the scraper 2 is completed.

Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
