[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1-Figure 5 As shown, in this embodiment, an environmentally friendly drum screen includes a support seat 1, a side plate 2 is fixedly connected to the top of the support seat 1, a feed hopper 3 is fixedly connected to one side of the side plate 2, and a drum screen body 5 is rotatably connected to the other side of the side plate 2, and the output end of the feed hopper 3 extends to the inside of the drum screen body 5, and a power component is arranged on the outside of the side plate 2, and the power component is used to drive the drum screen body 5 to rotate, and a discharge channel 4 is opened inside the support seat 1, and a moving plate 12 is slidably connected between the inner walls of the discharge channel 4, and a ramp plate 16 is arranged at the bottom of the moving plate 12, and the bottom surface of the ramp plate 16 is in contact with the discharge channel 4. The bottom surface of the channel 4 is slidably connected, and a displacement component is arranged inside the support seat 1, which is used to drive the ramp plate 16 to move. A sub-screen 6 is arranged inside the drum screen body 5, and the drum screen body 5 and the sub-screen 6 are both made of wear-resistant stainless steel. A slide groove 13 is provided at the bottom of the movable plate 12, and a fixed block 14 is fixedly connected to the top of the ramp plate 16. The outer side of the fixed block 14 is slidably connected to the inner wall of the slide groove 13, and a spring 15 is fixedly connected between the top of the fixed block 14 and the top of the inner wall of the slide groove 13, and triangular baffle plates 17 are fixedly connected to both sides of the inner wall of the discharge channel 4.

[0024] When the industrial raw materials are screened, the industrial raw materials to be screened are introduced into the drum screen body 5 through the feed hopper 3, and then the drum screen body 5 is driven by the power component to rotate on one side of the side plate 2. Through the rotation of the drum screen body 5, the sub-screen 6 inside the drum screen body 5 screens the industrial raw materials, and the screened industrial raw materials fall along the discharge channel 4 and roll toward the outside of the support seat 1 under the action of the triangular baffle plate 17 and the slope of the bottom surface of the discharge channel 4, so as to facilitate the discharge of the screened working raw materials. After the screening work is completed, the inclined plate 16 is driven by the displacement component to move toward the outlet of the discharge channel 4 under the action of the moving plate 12. During the movement, the industrial raw materials attached to both sides of the discharge channel 4 are scraped off by the cooperation of the inclined plate 16 and the moving plate 12. At the same time, the spring 15 arranged inside the slide 13 pushes the bottom inclined surface of the ramp plate 16 to always fit the inclined surface of the bottom of the discharge channel 4, so that the staff can clean the inside of the discharge channel 4 to avoid the deposition of industrial raw materials and affect the subsequent use.

[0025] like Figure 1-Figure 5 As shown, the displacement assembly includes a first side groove 7 and a second side groove 8, and the first side groove 7 and the second side groove 8 are both opened inside the support seat 1, and the side where the first side groove 7 and the second side groove 8 are close to each other is communicated with the discharge channel 4, and a threaded rod 9 is rotatably connected between the inner walls of the first side groove 7, and a moving block 10 is threadedly connected to the outer side of the threaded rod 9, and one side of the moving block 10 is fixedly connected to the moving plate 12, and a slider 11 is slidably connected between the inner walls of the second side groove 8, and one side of the slider 11 is fixedly connected to the moving plate 12, and an installation groove 19 is opened inside the support seat 1, and a servo motor 20 is fixedly installed inside the installation groove 19, and the output end of the servo motor 20 extends to the inside of the first side groove 7 and is fixedly connected to the threaded rod 9.

[0026] The threaded rod 9 is driven by the servo motor 20 to rotate between the inner walls of the first side groove 7. Since the moving block 10 is threadedly connected to the threaded rod 9, the moving block 10 will drive the moving plate 12 to move between the inner walls of the discharge channel 4 under the guidance of the slider 11 while the threaded rod 9 rotates, thereby driving the ramp plate 16 under the moving plate 12 to move at the same time, thereby facilitating the cleaning of the inside of the discharge channel 4 after the use of the drum screen is completed, facilitating the deposition of raw materials, and affecting the subsequent use of the drum screen.

[0027] like Figure 1-Figure 5 As shown, the power assembly includes an L-shaped mounting plate 21, which is fixedly connected to one side of the side plate 2. A power motor 22 is fixedly installed on one side of the L-shaped mounting plate 21. The output end of the power motor 22 passes through the side plate 2 and is fixedly connected to the center axis 18. Four connecting plates 23 are fixedly connected between the center axis 18 and the drum screen body 5.

[0028] The power motor 22 drives the central shaft 18 to rotate on one side of the side plate 2, thereby driving the drum screen body 5 to rotate on one side of the side plate 2 at the same time under the action of the connecting plate 23. While the drum screen body 5 rotates, the sub-screen 6 arranged inside the drum screen body 5 is used to complete the screening and grading of industrial raw materials.

[0029] The utility model provides an environmentally friendly drum screen, and the specific working principle is as follows: when the industrial raw materials are screened, the industrial raw materials to be screened are introduced into the drum screen body 5 through the feed hopper 3, and then the central shaft 18 is driven to rotate on one side of the side plate 2 by the power motor 22, thereby driving the drum screen body 5 to rotate on one side of the side plate 2 at the same time under the action of the connecting plate 23, and through the rotation of the drum screen body 5, the sub-screen 6 inside the drum screen body 5 screens the industrial raw materials, and the screened industrial raw materials fall along the discharge channel 4, and under the action of the triangular baffle plate 17 and the bottom slope of the discharge channel 4, they are moved to the support seat 1 rolls on the outer side of the discharge channel 4. After the screening work is completed, the threaded rod 9 is driven to rotate between the inner walls of the first side groove 7 by the servo motor 20. Since the moving block 10 is threadedly connected with the threaded rod 9, the moving block 10 will drive the moving plate 12 to move between the inner walls of the discharge channel 4 under the guidance of the slider 11 while the threaded rod 9 rotates. In the process of moving, the industrial raw materials attached to the two sides of the discharge channel 4 are scraped off by the cooperation of the ramp plate 16 and the moving plate 12. At the same time, the spring 15 arranged inside the slide 13 pushes the bottom inclined surface of the ramp plate 16 to always fit the inclined surface at the bottom of the discharge channel 4.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
