Description

Technical Field

[0001] The utility model relates to the field of rolling screens for construction, in particular to a rolling screen device which is easy to clean and is used in construction engineering. Background Art

[0002] The drum screen is a widely used machine in sorting technology. It controls the sorting by the particle size and has high sorting accuracy. The drum screen is generally divided into several sections, and the screen holes are arranged from small to large. The screen holes on each section have the same diameter. The device can be used to screen building materials in construction projects. Therefore, a drum screen device that is easy to clean for construction projects is proposed.

[0003] The problem with the prior art is that some building materials will remain in the drum screen after multiple screenings, and these remaining building materials will affect subsequent use, so it is necessary to clean these remaining disassembled materials.

The positioning mechanism is driven to enter the interior of the fixing groove by pulling the adjusting mechanism. At this time, the clamping block can be operated to disassemble and clean the roller shaft and the drum screen, thereby solving the problem that some building materials will remain in the drum screen after multiple screenings. These residual building materials will affect the subsequent use, so it is necessary to clean these residual demolished materials. Therefore, a method for quickly disassembling the drum screen and cleaning it is proposed.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] Roller screen devices for easy cleaning in construction projects, such as Figures 1 to 4 As shown, it includes a support base 100, the inner wall of the support base 100 is rotatably connected to a cleaning mechanism 200, one side of the support base 100 is fixedly connected to a water spraying mechanism 300, and the bottom end of the water spraying mechanism 300 is fixedly connected to a lifting mechanism 400; the cleaning mechanism 200 includes a rotating shaft 210 rotatably connected to the inner wall of the support base 100, the outer wall of the rotating shaft 210 is rotatably sleeved with a connecting ring 220, the outer wall of the rotating shaft 210 is fixedly connected to a cleaning assembly 230, the outer wall of the connecting ring 220 is fixedly connected to a rotating assembly 240, one side of the connecting ring 220 is fixedly connected to a drum screen 600, and one end of the rotating shaft 210 is connected to the output end of the motor 500 through a coupling; the cleaning assembly 230 includes a rotating rod 231 fixedly connected to the outer wall of the rotating shaft 210, the inner wall of the rotating rod 231 is rotatably connected to a connecting shaft 232, the outer wall of the connecting shaft 232 is fixedly connected to a rotating gear 233, and the outer wall of the connecting shaft 232 A cleaning roller 234 is fixedly sleeved on the wall, and an inner ring rack 235 is meshed with the rotating gear 233, and the inner ring rack 235 is fixedly connected to the connecting ring 220; the rotating assembly 240 includes a first sprocket 241 fixedly connected to the outer wall of the rotating shaft 210, the first sprocket 241 is meshed with a chain 242, the chain 242 is meshed with a second sprocket 243, the inner wall of the second sprocket 243 is fixedly connected to a supporting gear 244, the outer wall of the supporting gear 244 is fixedly connected to a second supporting shaft 245, the second supporting shaft 245 is meshed with an outer ring rack 246, and the outer ring rack 246 is fixedly connected to the connecting ring 220; a supporting wheel 260 is fitted on the outer wall of the connecting ring 220, and the inner wall of the supporting wheel 260 is rotatably connected to the first supporting shaft 250, the first supporting shaft 250 is fixedly connected to the support seat 100, and two groups of connecting rings 220 are provided, and the two groups of connecting rings 220 are symmetrically arranged at both ends of the drum screen 600.

[0029] When cleaning the drum screen 600, the starting motor 500 drives the rotating shaft 210 to rotate, thereby driving the rotating rod 231 to rotate, and then driving the connecting shaft 232 to rotate with the rotating shaft 210 as the axis. Due to the meshing between the rotating gear 233 and the cleaning roller 234, the connecting shaft 232 drives the rotating gear 233 to rotate with the rotating shaft 210 as the axis, and the rotating gear 233 itself also rotates with the connecting shaft 232 as the axis, thereby driving the connecting shaft 232 itself to rotate, and then driving the cleaning roller 234 to rotate with the connecting shaft 232 as the axis when it is in contact with the inner side of the drum screen 600, thereby increasing the area of ​​the cleaning roller 234 in contact with the inner side of the drum screen 600 and improving the cleaning efficiency at the same time; the rotation of the rotating shaft 210 drives the first sprocket 241 to rotate, thereby driving the second chain 242 that is also meshed with the chain 242 The wheel 243 rotates around the support gear 244, thereby driving the second support shaft 245 to rotate. The second support shaft 245 drives the outer ring rack 246 to rotate, thereby driving the connecting ring 220 to rotate, and then driving the drum screen 600 to rotate. Since the second support shaft 245 and the rotating shaft 210 have the same rotation direction, the outer ring rack 246 and the rotating shaft 210 rotate in the opposite direction, thereby driving the drum screen 600 to rotate in the opposite direction to the rotation direction of the rotating shaft 210 when rotating around the rotating shaft 210. The rotation directions of the drum screen 600 and the cleaning roller 234 when rotating around the rotating shaft 210 are opposite, so that the cleaning roller 234 cleans the inside of the drum screen 600 more comprehensively and efficiently. Because the drum screen 600 is for screening building materials, the cleaning roller 234 can be a brush or steel brush made of a harder material.

[0030] Please refer to Figure 3 The water spray mechanism 300 includes a water spray box 310 fixedly connected to one side of the support seat 100, a piston block 320 is slidably connected to the inner wall of the water spray box 310, a water spray pipe 330 is connected to the inner wall of the water spray box 310, and a water inlet pipe 350 is connected to the inner wall of the water spray box 310; a first one-way valve 340 is fixedly connected to the inner wall of the water spray pipe 330, and a second one-way valve 360 ​​is fixedly connected to the inner wall of the water inlet pipe 350. The water spray pipe 330 and the first one-way valve 340 are both provided with multiple groups, and the bottom end of the piston block 320 is fixedly connected to the lifting mechanism 400.

[0031] The piston block 320 moves back and forth longitudinally along the inner wall of the water spray box 310 driven by the lifting mechanism 400. When the piston block 320 moves downward, the water inlet pipe 350 connected to the water source introduces water into the inner cavity of the water spray box 310. When the piston block 320 moves upward, the water in the inner cavity of the water spray box 310 is sprayed out through the water spray pipe 330 and sprayed toward the drum screen 600, helping the cleaning component 230 to better clean the drum screen 600. According to the principle of the one-way valve, when the piston block 320 moves downward, water can enter the water spray box 310 through the second one-way valve 360, and substances outside the water spray box 310 cannot enter the inner cavity of the piston block 320 through the first one-way valve 340; and when the piston block 320 moves upward, water in the inner cavity of the water spray box 310 can flow out of the water spray box 310 through the first one-way valve 340, while water in the inner cavity of the piston block 320 cannot flow back to the water inlet pipe 350 through the second one-way valve 360.

[0032] Please refer to Figure 4 The lifting mechanism 400 includes a connecting rod 450 fixedly connected to the bottom end of the piston block 320, one end of the connecting rod 450 is fixedly connected to the moving plate 430, the moving plate 430 is provided with an inclined groove 440, a positioning shaft 420 is slidably connected in the inclined groove 440, one end of the positioning shaft 420 is fixedly connected to the disk 410, and the inner wall of the disk 410 is fixedly connected to the rotating shaft 210.

[0033] When the cleaning component 230 cleans the drum screen 600, the rotation of the rotating shaft 210 drives the disc 410 to rotate, thereby driving the positioning shaft 420 to rotate eccentrically with the rotating shaft 210 as the axis. Since the movable plate 430 can only move longitudinally under the restriction of the connecting rod 450 and the support seat 100, when the positioning shaft 420 moves, it slides in the inclined groove 440 and drives the movable plate 430 to move longitudinally back and forth, thereby driving the connecting rod 450 to move longitudinally back and forth, and then driving the piston block 320 to move longitudinally back and forth. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

[0034] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
