[0002] Cement tube mill is an important equipment in cement production. The main structure of cement tube mill includes cylinder, liner, grinding body, transmission device and discharge grate plate, etc. It mainly relies on the rotation of cylinder to bring the material and grinding body to a certain height and then drop it. The material is ground by the impact and grinding action of the grinding body on the material. When the material is ground, it flows out through the discharge grate plate. The discharge grate plate can well control the outflow of material. The gaps on the grate plate allow the ground material to pass through, while the larger particles of material are blocked in the mill for further grinding. Usually, the grate plate is spliced ​​into a whole by multiple sector-shaped grate plates, so that it is convenient to disassemble and repair the grate plate in a targeted manner after wear and clogging of the screen hole.

The mounting plate 3 is a circular structure as a whole, and the cross-section of the mounting plate 3 is a "concave"-shaped structure. The driving platform 404 is a truncated cone structure, and the protrusion 405 is a trapezoidal structure.

[0026] As a technical optimization solution of the present invention, the grate plate body 5 is a fan-shaped structure as a whole, the cross-section of the retaining ring 401 is an "L"-shaped structure, and the cross-section of the stop block 402 is an "L"-shaped structure; after the retaining ring 401 and the stop block 402 cooperate to press against the grate plate body 5, the grate plate body 5 can no longer move, thereby increasing the stability of the grate plate body 5 after installation.

[0027] As a technical optimization solution of the present invention, both ends of the grate plate body 5 are provided with a slope structure, and the ends of the retaining ring 401 and the stop block 402 are provided with a slope structure; the slope structure has a left and right guide function, which makes it more convenient for the grate plate body 5 to engage with the retaining ring 401 and the stop block 402, and the setting of the slope makes the contact end between the grate plate body 5 and the retaining ring 401 and the contact end between the grate plate body 5 and the stop block 402 gradually thicken, so that the grate plate body 5 and the retaining ring 401 and the stop block 402 are in increasingly close contact.

[0028] As a technical optimization solution of the present invention, a fixing sleeve 408 is fixedly connected to the mounting plate 3, and the slide rod 406 is slidably connected to the fixing sleeve 408. The outer sleeve of the slide rod 406 is provided with a tension spring 407, one end of the tension spring 407 is fixedly connected to the fixing sleeve 408, and the other end of the tension spring 407 is fixedly connected to the stop block 402; when disassembly is required, the drive platform 404 is driven to slide upward by the screw rod 403 and no longer conflicts with the protrusion 405. At this time, the tension spring 407 is reset, driving the stop block 402 and the slide rod 406 to move toward the fixed sleeve 408, so that the stop block 402 no longer conflicts with the grate plate body 5, thereby releasing the fixation of the grate plate body 5.
