[0014] Next, with reference to the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1 , the present utility model provides a technical solution: a locking device for a trash rack cleaning machine.

[0016] In this implementation scheme:

[0017] Select two steel plates with a width of 28 cm and a length of 60 cm equal to the width of the top of the cleaning machine as the top plates, and weld them to two steel plates with a width of 39 cm and a length of 60 cm as the web plates respectively to form two box-type structures; use the two ends of the top of the cleaning machine as the bottom plates, and weld the two box-type structures to the two ends of the top of the cleaning machine respectively. The welds are all 16 mm fillet welds to ensure perpendicularity and parallelism, and use this box-type structure as the outer box 3;

[0018] Cut two steel blocks with lengths, widths and heights of 80 cm, 22 cm and 35 cm respectively as the inner box 4;

[0019] Bend both ends of two 40-cm-long steel bars with a diameter of 3 cm to one side to form a C shape, and weld them to one end of the inner box 4 respectively to form a handle. This handle structure serves as the push-pull handle 7;

[0020] Insert the inner box 4 into the outer box 3. Use a tapping machine to drill Φ52 holes in the middle of the web of the outer box 3 at both ends 30 cm from the top of the cleaning machine. The tapping machine passes through the front web of the outer box 3, the inner box 4, and the rear web of the outer box 3 in sequence.
