DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 A sieve barrel of an environmentally friendly waste crushing and screening machine comprises a screening body 1, in which a sieve hole size adjustment device 2 is slidably inserted.

[0018] Specifically, the screening body 1 includes a barrel body 11, and a plurality of evenly arranged sieve holes 12 are provided on the outer wall of the barrel body 11. The sieve hole size adjustment device 2 includes a plurality of annular evenly distributed insertion strips 21, and the insertion strips 21 are slidably inserted into the barrel body 11. A second annular plate 22 is fixedly connected to one end of the insertion strips 21. A plurality of filter holes 23 are provided on the insertion strips 21. The filter holes 23 correspond to the sieve holes 12 one by one, and the two have the same size. By sliding the insertion strips 21, the filter holes 23 and the sieve holes 12 can be offset from each other, thereby adjusting the size of the sieve holes 12, and particles of different sizes can be screened.

[0019] Furthermore, the screening body 1 further comprises a first annular plate 13 , which is fixedly mounted on the end of the barrel body 11 , and a plurality of annularly evenly distributed insertion holes 14 are formed on the end surface of the first annular plate 13 , and the insertion strips 21 are slidably inserted into the insertion holes 14 .
