DETAILED DESCRIPTION

[0023] The direction words mentioned in the following embodiments, such as 'up', 'down', 'left', 'right' and the like, are only the directions of the drawings, therefore, the direction words used are used for illustration but not for limiting the utility model creation.

[0024] For example, Figures 1-4As shown, a polyurethane sieve plate quick-disassembly and quick-assembly structure includes a sieve plate 1 and a fixing seat 2; the rear side of the sieve plate 1 is fixedly connected to a first limiting plate 11, and the left and right sides of the front end of the sieve plate 1 are fixedly connected to a second limiting plate 12; the fixing seat 2 includes a fixing frame 22 and a base 21, the base 21 is door-shaped, a fixing hole is provided in the middle of the base 21, and the fixing frame 22 is provided on the inner side of the base 21; the rear part of the base 21 is provided with a first limiting groove 211 corresponding to the first limiting plate 11, and the base 21 is provided with a fixing hole. The front part of the sieve plate 1 is provided with a second limiting groove 212 corresponding to the second limiting plate 12, the first limiting plate 11 is plugged into the first limiting groove 211, and the second limiting plate 12 is plugged into the second limiting groove 212; when in use, the sieve plate 1 is directly placed on the fixing frame 22, and then the sieve plate 1 is pushed forward, and the rear end and the front end of the sieve plate 1 will be respectively embedded in the base 21, thereby realizing the fixation of the sieve plate 1. When disassembling, it can be directly pulled to prevent the sieve plate 1 from moving up and down, with high stability and high disassembly and assembly efficiency.

[0025] Specifically, the opening of the first limiting groove 211, specifically, the upper edge of the opening of the first limiting groove 211 is provided with a first chamfer 213, and the rear edge of the first limiting plate 11 is provided with a first rounded corner, so that the first limiting plate 11 can be smoothly inserted into the first limiting groove 211.
