[0025] It should be noted here that: through the setting of the adjusting mechanism, the eccentric distance between the driving round plate 204 and the adjusting round plate 202 is changed under the moving action of the moving assembly, so that the impact force of the beating plate 104 on the drum sieve body 102 is changed by changing the eccentric distance, so as to further realize the adjustment of the beating force of the drum sieve body 102, so as to adapt to the beating force requirement of the drum sieve body 102 when screening different properties of materials, thereby ensuring the beating frequency of the drum sieve body 102 while improving the flexibility of beating the drum sieve body 102.

[0026] Please refer to Figure 4 , the adjusting round plate 202 and the driving round plate 204 are eccentrically arranged in the figure;

[0027] It should be noted that: due to the eccentricity of the driving circular plate 204 and the adjusting circular plate 202, the annular groove 401 and the driving rod 402 under the interaction force and the guiding effect of the guiding assembly drive the beating plate 104 at one end of the driving plate 403 to move up and down.

[0028] Please refer to Figure 4 , the fixed plate 201 in the figure is provided with a rotating part for rotating the adjusting circular plate 202, the rotating part is a rotating motor 3 fixedly connected to the side of the fixed plate 201 away from the adjusting circular plate 202, the output end of the rotating motor 3 is connected with a rotating shaft;

[0031] It should be noted that: through the arrangement of the driving mechanism, the beating plate 104 at one end of the driving plate 403 is driven to move up and down, thereby realizing the reciprocating beating of the drum sieve body 102.

[0032] Working principle: when the drum sieve body 102 needs to be beaten, the rotating motor 3 is started to drive the adjusting circular plate 202 at one end of the rotating shaft to rotate, in the process of rotating the adjusting circular plate 202, the driving circular plate 204 will be driven to rotate synchronously by the adjusting plate 203, because the driving circular plate 204 and the adjusting circular plate 202 are eccentrically arranged, therefore, in the process of rotating the driving circular plate 204, the beating plate 104 at one end of the driving plate 403 is driven to move up and down by the interaction force of the annular groove 401 and the driving rod 402 and the guiding effect of the guiding assembly, thereby realizing the reciprocating beating of the drum sieve body 102;

[0033] When the drum screen body 102 is used to screen materials with different properties, the beating force of the beating plate 104 on the drum screen body 102 needs to be adjusted due to the different viscosity and dryness of the materials with different properties. When the beating force of the beating plate 104 is adjusted, the eccentricity between the driving disc 204 and the adjusting disc 202 is changed under the action of the moving assembly, so that the impact force of the beating plate 104 on the drum screen body 102 is changed by changing the eccentricity, thereby further adjusting the beating force of the drum screen body 102 to adapt to the beating force requirement of the drum screen body 102 when screening materials with different properties, thereby ensuring the beating frequency of the drum screen body 102 while improving the flexibility of the beating of the drum screen body 102.
