[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0029] Please refer to Figure 1-Figure 4 As shown, a shaftless drum screen for the front end of construction and decoration waste includes a drum screen frame 1, a drum screen 2, and a driving device 3, characterized in that: the drum screen frame 1 includes a frame 13, a material conveyor belt 4 is arranged on the frame 13, a supporting wheel 11 and a blocking wheel 12 are arranged above the material conveyor belt 4, a drum screen 2 is arranged above the supporting wheel 11 and the blocking wheel 12, the drum screen 2 is covered with a cover shell 14 on the periphery of the drum screen 2, the cover shell 14 is fixedly connected to the frame 13, the material conveyor belt 4 is inclined and connected to the frame 13, the drum screen 2 is parallel to the material conveyor belt 4, the inclination direction is that the feed port is higher than the discharge port, the drum screen 2 includes a gear ring 21, the gear ring 21 is arranged on the outer circumference of the drum screen 2, and is located at the feed port, the driving device 3 includes a gear 31, the gear 31 is meshed with the gear ring 21, the gear The rotating shaft 31 is fixedly connected to the output shaft of the motor 32, and the motor 32 is fixedly installed on the frame 13. When in use, the gear ring 21 arranged on the outer circumference of the drum screen 2 is meshed with the gear 31. Since the rotating shaft of the gear 31 is fixedly connected to the output shaft of the motor 32, the drum screen 2 can be driven to rotate. Since a supporting wheel 11 and a stop wheel 12 are arranged below the drum screen 2 to support the drum screen, the drum screen 2 can be stably rotated by the supporting wheel 11 and the stop wheel 12 when rotating. Since a cover shell 14 is arranged on the periphery of the drum screen 2 for protection, the drum screen 2 can be wrapped and covered to prevent material from splashing during the screening process. Since the drum screen 2 is arranged tilted, the construction waste screened inside the drum screen 2 moves in the tilted direction under the action of gravity, and by arranging a material conveyor belt 4 below the drum screen 2, the construction waste screened by the drum screen 2 falls onto the material conveyor belt 4 for transportation.

[0030] Please refer to Figure 5 As shown, the outer circumference of the drum screen 2 is formed with a vibration ring 23, which is located above the supporting wheel 11 and is in an irregular ring shape. During use, since the vibration ring 23 is in an irregular ring shape, the drum screen 2 will vibrate when it contacts the supporting wheel 11 during operation, so that the drum screen 2 will vibrate while rotating, driving the construction waste inside the drum screen 2 to vibrate, thereby preventing the construction waste from clogging the screen holes.

[0031] Please refer to Figure 6As shown, the inner wall of the drum screen 2 is formed with a bag breaking cone 22 and a guide piece 24, and the bag breaking cone 22 is located at the feeding port of the drum screen 2, and the guide piece 24 is spirally fixed on the inner wall of the drum screen 2. When in use, since the inner wall of the drum screen 2 is formed with the bag breaking cone 22, the plastic and woven bags containing construction waste can be effectively broken to screen the construction waste in the bags. Since the guide piece 24 is spirally fixed on the inner wall of the drum screen 2, when the drum screen 2 rolls, the construction waste inside the drum screen 2 can be spirally transported under the guidance of the spirally arranged guide piece 24.

[0032] Working principle: the construction and decoration waste materials to be screened are put into the drum screen 2 through the loader, and the output shaft of the motor 32 in the driving device 3 is connected to the gear 31. The gear 31 is meshed with the gear ring 21 arranged outside the drum screen 2 to drive the drum screen 2 to rotate. During screening, the bag breaking cone 22 in the drum screen 2 rotates with the drum screen 2 and effectively breaks the plastic and woven bags of construction waste. The construction waste in the broken bags is screened in the drum screen 2, and the construction waste is spirally transported under the guidance of the guide piece 24 spirally arranged inside the drum screen 2. During screening, the irregular surface of the vibration ring 23 contacts the supporting wheel 11, so that the drum screen 2 vibrates simultaneously during the rotation process, driving the construction waste inside the drum screen 2 to vibrate, and preventing the construction waste from clogging the screen hole. The screened materials fall onto the material conveyor belt 4, and the screened construction waste is transported through the material conveyor belt 4 to achieve the effect of screening solid waste materials.

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
