The device can be made more reliable.
Because still including fixed block 10, first baffle 605 left end is opened has the external screw thread, and first baffle 605 left side is equipped with fixed block 10, and last division of fixed block 10 has screw 11, and fixed block 10 passes through threaded connection with first baffle 605. The fixing block 10 prevents the first blocking plate 605 from being separated from the second through hole 604 when moving left and right.
The bottom plate 1 and the n-shaped plate 4 are made of Q235 steel, the bottom plate 1 is rectangular, the height of the bottom plate 1 is at least 5cm, the length of the bottom plate 1 is at least 1.5 m, the bottom plate 1 is high in bearing strength, not prone to abrasion and long in service life.
Because the mesh plate 302 and the mesh baffle 703 are made of stainless steel, the mesh plate 302 is arc-shaped, and the service life of the invention can be prolonged.
The above examples are merely representative of preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, various changes, modifications and substitutions can be made without departing from the spirit of the present invention, and these are all within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
