[0002] The drum screen is a very widely used machine in sorting technology. It controls the garbage sorting by the particle size. The drum is installed obliquely on the frame. When the drum rolls, the material rolls and moves along the inclined surface, and the material moves from small mesh to large mesh to achieve graded screening. It is often used for screening sand and gravel.

[0003] Since the surface of sand and gravel is relatively rough, when the drum screen is screening sand and gravel, it will produce friction with the sand and gravel. The friction force will cause the protective paint on the surface of the drum screen to fall off, thereby accelerating the oxidation of the drum screen and shortening the service life of the drum screen.

It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1-Figure 5 The present invention provides a technical solution for a drum screen structure that is convenient for loading and unloading materials: the box body 1 includes: a cleaning structure and a protective structure, the cleaning structure includes a clean water tank 6, the outer wall of the clean water tank 6 is fixedly connected to the left side of the upper interior of the box body 1, the protective structure includes a protective paint box 7, the outer wall of the protective paint box 7 is fixedly connected to the right side of the upper interior of the box body 1; the bottom of the box body 1 is fixedly connected to the discharge port 3, one side of the box body 1 is fixedly connected to the feed port 2, the inside of the box body 1 is rotatably connected to the drum screen body 4, and the outer wall of the drum screen body 4 is fixedly connected to a magnet 5.

[0027] By putting sand and gravel into the box body 1 through the feed port 2, and then driving the drum screen body 4 to rotate by the rotating shaft, the sand and gravel inside the drum screen body 4 can be screened, and the sand and gravel falling through the drum screen body 4 can be collected through the discharge port 3 at the bottom of the box body 1.

[0028] Example 2

[0029] On the basis of embodiment 1, the bottom of the clean water tank 6 is fixedly connected with an electric telescopic rod 64, the bottom of the electric telescopic rod 64 is fixedly connected with the installation box 61, the top of the installation box 61 is fixedly connected with a sleeve 62, the outer wall of the sleeve 62 passes through the bottom of the clean water tank 6, the outer wall of the sleeve 62 is movably connected to the bottom of the clean water tank 6, the internal sliding connection of the sleeve 62 is connected to the limit rod 63, the top of the limit rod 63 is fixedly connected to the inner wall of the clean water tank 6, the outer wall of the sleeve 62 is provided with a through hole 65, the interior of the sleeve 62 is hollow, the bottom of the installation box 61 is provided with a plurality of through holes 68, and one side of the installation box 61 is provided with a slide groove 69, the interior of the slide groove 69 is fixedly connected with a return spring 611, one end of the return spring 611 is fixedly connected to a slider 610, the outer wall of the slider 610 is slidably connected to the interior of the slide groove 69, the bottom of the slider 610 is fixedly connected with a movable plate 67, and the bottom of the movable plate 67 is fixedly connected with a brush 2 66.

[0030] When the cleaning is completed, the electric telescopic rod 64 can be started. The electric telescopic rod 64 moves upward, so that the installation box 61 can drive the second through-hole 68 to move upward. When the second through-hole 68 leaves the surface of the drum screen body 4, the friction force disappears. Without the action of friction force, the return spring 1 611 can drive the movable plate 67 to return to its original position, thereby preventing dust from entering the drum screen body 4 through the second through-hole 68 when the drum screen body 4 is working, thereby correspondingly improving the cleaning effect of the water quality.

[0031] Example 3

[0032] On the basis of Example 2, the bottom of the protective paint box 7 is fixedly connected with a telescopic tube 72, the outer wall of the telescopic tube 72 is connected to the bottom of the protective paint box 7, the bottom of the telescopic tube 72 is fixedly connected with a temporary storage tank 71, the bottom of the temporary storage tank 71 is fixedly connected with a reset spring 2 73, one end of the reset spring 2 73 is fixedly connected with a magnet 2 77, the bottom of the magnet 2 77 is fixedly connected with a brush 1 78, the top of the magnet 2 77 is fixedly connected with a blocking rod 76, the outer wall of the blocking rod 76 is slidably connected to the inside of the temporary storage tank 71, the top of the blocking rod 76 is fixedly connected with a base 75, the inside of the base 75 is rotatably connected with a stirring rod 74, and the bottom of the magnet 2 77 is attracted to the top of the magnet 1 5 at different levels.

[0033] When the blocking rod 76 drives the stirring rod 74 to move downward, the protective paint inside the temporary storage tank 71 has a certain viscosity. When the stirring rod 74 moves up and down in the protective paint, due to the viscosity of the protective paint, the stirring rod 74 generates friction with it, thereby rotating, avoiding uneven thickness of the protective paint, which affects the use effect, and correspondingly improves the uniform stirring of the protective paint, thereby increasing the use effect of the protective paint. Then, the brush 1 78 is inserted into the cavity of the drum screen body 4, so that the protective paint can be brought into the cavity of the drum screen body 4 when the protective paint enters the surface of the drum screen body 4, avoiding the cavity on the drum screen body 4 not being brushed with the protective paint, correspondingly improving the effect of brushing the protective paint, and increasing the service life of the drum screen body 4. By rotating the drum screen body 4 on the brush 1 78, the protective paint can be brushed evenly, avoiding uneven thickness of the protective paint, correspondingly increasing the smoothness of the appearance of the drum screen body 4, avoiding oxidation of the drum screen body 4, and correspondingly increasing the service life of the drum screen body 4.

[0034] In actual use, first, put the sand and gravel through the feed port 2, and then it can enter the interior of the box 1, and then the drum screen body 4 is driven to rotate by the rotating shaft, so that the sand and gravel inside the drum screen body 4 can be screened, and the sand and gravel falling through the drum screen body 4 can be collected through the discharge port 3 at the bottom of the box 1.

[0035] When the work of the drum screen body 4 is completed, the electric telescopic rod 64 at the bottom of the clean water tank 6 can be started, and then the movement of the electric telescopic rod 64 can drive the installation box 61 to move downward, so that the installation box 61 drives the second brush 66 downward. When the second brush 66 overlaps with the top of the drum screen body 4, the movement of the electric telescopic rod 64 can be stopped. When the installation box 61 moves downward, the sleeve 62 can be driven to slide on the limit rod 63, so that the passage 65 on the sleeve 62 moves to the bottom of the limit rod 63, so that the clean water inside the clean water tank 6 can be discharged through the passage. The first brush 65 enters the interior of the installation box 61, and then overlaps with the surface of the drum screen body 4 through the second brush 66, so that the dust on the surface of the drum screen body 4 can be removed when the drum screen body 4 rotates. The rotation of the drum screen body 4 and the second brush 66 generate resistance, so that the movable plate 67 drives the slider 610 to slide inside the chute 69. Through the movement of the chute 69, the movable plate 67 can be driven to the side of the second through-hole 68, so that the water inside the installation box 61 flows out through the second through-hole 68, thereby improving the cleaning efficiency of the second brush 66 on the drum screen body 4;

[0036] By setting the movable plate 67, when the drum screen body 4 is screening sand and gravel, dust is prevented from entering the interior of the installation box 61 through the second through hole 68, causing dirt to be generated inside the installation box 61 and clogging the second through hole 68, thereby correspondingly improving the performance and life of the installation box 61, making the water quality cleaner, increasing the water flow rate, and improving the cleaning effect of the surface of the drum screen body 4.

[0037] It should be noted that the clean water flowing from the inside of the installation box 61 to the surface of the drum screen body 4 can be wiped dry by the brush 2 66, which will not affect the practical protection. The force of the reset spring 1 611 itself is greater than the gravity of the slider 610, the movable plate 67 and the brush 2 66, and is less than the friction generated by the movement of the through hole 2 68 and the drum screen body 4.

[0038] When the temporary storage tank 71 is driven downward by the installation box 61, the distance between the second magnet 77 and the first magnet 5 can be shortened, so that the second magnet 77 and the first magnet 5 are attracted to each other at different levels, and the second magnet 77 can drive the blocking rod 76 to move downward. Through the downward movement of the second magnet 77, the bottom of the brush 1 78 can be inserted into the cavity on the drum screen body 4. When the blocking rod 76 moves downward, the smaller radius of the blocking rod 76 can enter the through hole 3 at the bottom of the temporary storage tank 71. Due to the middle of the blocking rod 76, the brush 1 78 can be inserted into the cavity on the drum screen body 4. The radius is smaller than the through hole three, so that the protective paint inside the temporary storage tank 71 can flow out from the through hole three and enter the surface of the drum screen body 4, and then be brushed evenly by the brush one 78. When the blocking rod 76 drives the stirring rod 74 to move downward, the protective paint inside the temporary storage tank 71 has a certain viscosity. When the stirring rod 74 moves up and down in the protective paint, the viscosity of the protective paint causes friction between the stirring rod 74 and the protective paint, thereby rotating, thereby stirring the protective paint evenly, thereby increasing the use effect of the protective paint;

[0039] When the blocking rod 76 drives the stirring rod 74 to move downward, the protective paint inside the temporary storage tank 71 has a certain viscosity. When the stirring rod 74 moves up and down in the protective paint, due to the viscosity of the protective paint, the stirring rod 74 generates friction with it, thereby rotating, avoiding uneven thickness of the protective paint, which affects the use effect, and correspondingly improves the uniform stirring of the protective paint, thereby increasing the use effect of the protective paint. Then, the brush 1 78 is inserted into the cavity of the drum screen body 4, so that the protective paint can be brought into the cavity of the drum screen body 4 when the protective paint enters the surface of the drum screen body 4, avoiding the cavity on the drum screen body 4 not being brushed with the protective paint, correspondingly improving the effect of brushing the protective paint, and increasing the service life of the drum screen body 4. By rotating the drum screen body 4 on the brush 1 78, the protective paint can be brushed evenly, avoiding uneven thickness of the protective paint, correspondingly increasing the smoothness of the appearance of the drum screen body 4, avoiding oxidation of the drum screen body 4, and correspondingly increasing the service life of the drum screen body 4.

[0040] It should be noted that the force of the return spring 2 73 itself is smaller than the force of attraction between the magnet 2 77 and the magnet 1 5 , but is larger than the gravity of the magnet 2 77 and the brush 1 78 .

[0041] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
