[0022] 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 described embodiments are only 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.

[0023] Reference Figure 1 - Figure 3The utility model provides an embodiment: a drum screen that is easy to replace, including a fixed frame 1, the interior of the fixed frame 1 is fixedly connected with a motor 2, the output end of the motor 2 is fixedly connected with a turntable 3, the outer wall of the turntable 3 is fitted with a mounting plate 4, the outer wall of the turntable 3 is rotatably connected with a rotating sleeve 5, the inner wall of the rotating sleeve 5 is fixedly connected with a gear ring 6, the interior of the turntable 3 is rotatably connected with a gear 7, the gear ring 6 meshes with the gear 7, the outer wall of the turntable 3 is fixedly connected with a positioning sleeve 8, the internal thread of the gear 7 is connected with a screw rod 9, one end of the screw rod 9 is rotatably connected with a push block 10, the outer wall of the push block 10 is slidably connected with a card block 11, the outer wall of the card block 11 is slidably connected to the inside of the mounting plate 4 and the positioning sleeve 8, the outer wall of the card block 11 is fixedly connected with a telescopic rod 12, the outer wall sleeve of the telescopic rod 12 is provided with a spring 13, both ends of the spring 13 are fixedly connected to the outer wall of the card block 11, and the outer wall of the mounting plate 4 is provided with a screening component;

[0024] Specifically, first, when the driving rotating sleeve 5 starts to rotate on the outer wall of the turntable 3, it will drive the gear ring 6 to rotate synchronously inside the turntable 3. There is a precise meshing relationship between the gear ring 6 and the gear 7, so that the gear 7 can rotate closely following the rotation trajectory of the gear ring 6. As the gear 7 rotates, the screw 9 connected thereto begins to move linearly. One end of the screw 9 is closely connected to the push block 10. Therefore, when the screw 9 moves, the push block 10 will also slide accordingly inside the positioning sleeve 8. The movement of the push block 10 produces direct pressure on the block 11, ensuring that the block 11 can slide smoothly inside the mounting plate 4 and the positioning sleeve 8. At the same time, the telescopic function of the spring 13 plays a key role here. It can not only absorb and buffer the impact force generated when the push block 10 moves, but also ensure the stability of the block 11 during the sliding process, thereby realizing efficient disassembly and assembly of the mounting plate 4 and the drum screen on one side of the mounting plate 4.

[0025] Reference Figure 1 and Figure 4 The screening assembly includes a drum screen plate 14, the inner wall of the drum screen plate 14 is arranged on the outer wall of the mounting plate 4, a sub-buckle 15 is fixedly connected to one side of the outer wall of the drum screen plate 14, a female buckle 16 is fixedly connected to the other side of the outer wall of the drum screen plate 14, a connecting rod 19 is fixedly connected to the outer wall of the mounting plate 4, the connecting rod 19 is fitted with the drum screen plate 14, one end of the connecting rod 19 is fixedly connected to a sliding sleeve 20, the outer wall of the fixed frame 1 is fixedly connected to a support 22, the outer wall of the support 22 is rotatably connected to a limiting wheel 21, the outer wall of the limiting wheel 21 is rotatably connected to the outer wall of the sliding sleeve 20, and the lower surface of the fixed frame 1 is fixedly connected to a bracket 17, a blanking plate 18 is arranged at the bottom of the bracket 17, and the inner wall of the bracket 17 is fixedly connected to the blanking plate 18;

[0026] Specifically, when the motor 2 is started, its output end will drive the turntable 3 to rotate, and the turntable 3 is connected to the drum screen through the mounting plate 4, thereby driving the drum screen to perform a rotary screening operation, realizing effective power transmission. In the process of the drum screen screening materials, its other end will drive the sliding sleeve 20 to slide on the outer wall of the limiting wheel 21, which not only ensures the stability of the rotation of the drum screen, but also reduces the vibration and noise of the equipment during operation. The ingenious design of the limiting wheel 21 enables the drum screen to always maintain a stable posture during the screening process, thereby improving the screening efficiency and the accuracy of material screening. When the drum screen needs to be disassembled and maintained, the drum screen plate 14 can be easily removed from the outer wall of the connecting rod 19 by tightening the bolts. In this process, pulling the drum screen plate 14 hard can smoothly separate the sub-buckle 15 from the mother buckle 16, so that the multiple drum screen plates 14 on the drum screen can be conveniently disassembled, thereby greatly simplifying the maintenance and replacement process. Finally, the screened material is smoothly transported through the unloading plate 18.

[0027] Working principle: When the drum screen that is easy to replace is needed, first drive the rotating sleeve 5 to rotate on the outer wall of the turntable 3, thereby driving the gear ring 6 to rotate inside the turntable 3, so that the gear 7 rotates with the rotation of the gear ring 6, and then the screw 9 is driven to move through the rotation of the gear 7, so that the push block 10 is driven to slide inside the positioning sleeve 8 through one end of the screw 9, and then the block 11 is pressed by the movement of the push block 10, and then the block 11 slides inside the mounting plate 4 and the positioning sleeve 8 with the expansion and contraction of the spring 13, so as to achieve the effect of disassembling and assembling the mounting plate 4 and the drum screen on one side of the mounting plate 4, and then the fixing frame 1 is used to fix the fixing frame 1. The output end of the motor 2 drives the turntable 3 to rotate, thereby driving the drum screen to rotate through the mounting plate 4 to screen the material. During this process, the other end of the drum screen will drive the sliding sleeve 20 to slide on the outer wall of the limiting wheel 21, so that the rotation of the drum screen is more stable. After the drum screen is disassembled, the drum screen plate 14 can be removed from the outer wall of the connecting rod 19 by tightening the bolts. During this process, the drum screen plate 14 is pulled hard to separate the sub-buckle 15 from the mother buckle 16, thereby splitting the multiple drum screen plates 14 on the drum screen, which is convenient for further splitting or replacement, and finally the screened material is transported through the unloading plate 18.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
