Description

Technical Field

[0001] The present invention relates to the technical field of vibrating screens, and specifically to a linear vibrating screen with a self-cleaning function. Background Art

[0002] A linear screen (linear vibrating screen) uses a vibrating motor for excitation as the vibration source, causing the material to be thrown up on the screen mesh and simultaneously move linearly forward. The material uniformly enters the feed inlet of the screening machine from the feeder, and through multiple layers of screen meshes, several specifications of oversize materials and undersize materials are produced and discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, a fully enclosed structure, no dust spillage, automatic discharging, and is more suitable for assembly line operations.

[0003] Publication No. CN 220406335 U discloses a linear vibrating screen with a self-cleaning function. When the screen needs to be cleaned after material screening, the motor and the forward and reverse motor are started through an external controller. The start of the motor will drive the brush roller to rotate. The brush roller cleans the screen mesh through rotation. The forward and reverse motor will drive the threaded rod to rotate. Through the thread inside the first mounting plate, the threaded rod will drive the first mounting plate to move. The first mounting plate drives the motor and the first pulley to move. The motor drives the brush roller, the connecting shaft and the second mounting plate to move. The second mounting plate drives the second pulley. Through the rotation of the threaded rod and the sliding of the first pulley and the second pulley in the movable groove, the brush roller moves and rotates along the surface of the screen mesh. When the brush roller reaches the bottom of the screen mesh, the external controller is used to start the reverse rotation of the forward and reverse motor, and the brush roller is moved to the top of the screen mesh. Such repeated operations are carried out until the screen mesh is cleaned. By using the cleaning device to clean the screen mesh, the time for manual cleaning is saved. However, the following problems still exist in the actual use of this patent: Although the linear vibrating screen with a self-cleaning function can achieve the cleaning of the screen mesh, when the vibrating screen is in use, it cannot automatically discharge materials according to the amount of materials on the screen mesh, and at the same time, the amount of discharged materials cannot be accurately controlled. When there is a large amount of materials on the screen mesh, material accumulation will occur, thus affecting the screening effect of the materials. When there is a small amount of materials on the screen mesh, the problem of affecting the material screening efficiency will occur.

[0004] Therefore, a linear vibrating screen with a self-cleaning function is proposed to solve the problems mentioned above. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For this linear vibrating screen with a self-cleaning function, by adjusting the rotation angle of the feeding box, the amount of material fed can be controlled, so that the material can be evenly distributed on the vibration screening mesh. It can automatically adjust the feeding amount of the feeding box according to the amount of material on the vibration screening mesh, and will not cause the phenomenon of accumulation and blockage of the vibration screening mesh due to the large amount of material. By appropriately tilting the screening box, it is convenient to screen the material and improve the screening effect of the material. The specific content is as follows: 1. By setting up a metering and feeding mechanism, not only can the vibrating screening net vibrate up and down, driving the support spring and the first meshing rack on one side to move up and down. Taking advantage of the characteristic that the first meshing rack is meshed and connected with the rotating gear, the first meshing rack on the other side drives the connecting support rod to descend. Under the action of the sliding connection between the limiting sliding rod and the limiting sliding sleeve inside the feeding rotating bracket, when the feeding rotating bracket rotates, it drives the feeding rotating rod to rotate. With the first connecting hinge, the rotation of the feeding box can be realized. By adjusting the rotation angle of the feeding box, the amount of material fed can be controlled, so that the material can be evenly distributed on the vibrating screening net. When there is a large amount of material on the vibrating screening net, due to the action of gravity, the vibrating screening net descends by a small amount. Under the action of the meshing connection between the rotating gear and the first meshing rack, the unfolding amplitude of the feeding baffle is small, so the feeding amount is small. When there is a small amount of material on the vibrating screening net, due to the action of gravity, the vibrating screening net descends by a large amount. Therefore, the unfolding amplitude of the feeding baffle is large, and the feeding amount is large. It can automatically adjust the feeding amount of the feeding box according to the amount of material on the vibrating screening net, and will not cause the phenomenon of accumulation and blockage of the vibrating screening net due to a large amount of material. At the same time, it will not affect the screening efficiency of the vibrating screening net due to a small amount of material. By starting the mixing motor to drive the mixing rotating rod, the mixing connecting rod and the mixing plate to rotate, the material inside the feeding box can be stirred to avoid the phenomenon of material accumulation and agglomeration, which affects the amount of material fed. When the vibrating screening net needs to be automatically cleaned, the external controller controls the cleaning water pump to pump the cleaning water out of the inside of the cleaning water tank and sprinkle it on the vibrating screening net through the cleaning nozzle, so as to automatically clean the vibrating screening net; 2. By setting up a vibrating screening mechanism, not only can the screening vibrating motor drive the screening box to vibrate, but also, under the elastic force of the screening spring and the vibrating spring, the vibration of the vibrating screening net can be realized, so as to screen the material. When the vibrating screening net needs to be cleaned, start the cleaning motor to drive the first sprocket transmission component and the cleaning threaded rod to rotate, so that the cleaning threaded sleeve drives the meshing gear and the cleaning roller to move. Taking advantage of the characteristic that the meshing gear is meshed and connected with the second meshing rack, the reverse rotation of the cleaning roller can be realized, which is convenient for cleaning impurities and dust to the discharge port of the screening box. By starting the electric telescopic rod to drive the second meshing rack to move up and down, the meshing and separation between the second meshing rack and the meshing gear can be realized, and the rotation and stop of the cleaning roller can be realized, which is convenient for cleaning the vibrating screening net. By starting the tilting motor to drive the second sprocket transmission component and the tilting threaded rod to rotate, the tilting threaded sleeve moves outside the tilting threaded rod and drives the first rotating bracket and the tilting rotating support plate to rotate. Under the action of the second rotating bracket and the second connecting hinge, the screening box can be tilted. By appropriately tilting the screening box, it is convenient for screening the material and improving the screening effect of the material. Description of the Drawings

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-5 , Figures 7-9, the present invention provides a technical solution: a linear vibrating screen with a self-cleaning function, including a quantitative feeding mechanism 1 and a cleaning water tank 121 installed on one side of the quantitative feeding mechanism 1. A vibrating screening mechanism 2 is arranged at the bottom of the quantitative feeding mechanism 1, and an inclined base 221 is arranged at the bottom of the vibrating screening mechanism 2. The quantitative feeding mechanism 1 includes a first fixed bracket 101. Limiting chutes 102 are symmetrically installed inside the first fixed bracket 101. A rotating gear 103 is rotatably connected to the central position inside the first fixed bracket 101. Among them, first meshing racks 104 are meshed and connected to both sides of the rotating gear 103. The first meshing racks 104 are slidably connected to the limiting chutes 102. A support spring 105 is fixedly installed at the bottom of one first meshing rack 104. Among them, a connecting support rod 106 is fixedly installed at the top of the other first meshing rack 104. A plurality of adjusting supports 107 are fixedly installed at the top of the connecting support rod 106. A feeding rotating bracket 108 is fixedly installed at the top of the adjusting support 107. A limiting sliding rod 109 is fixedly installed inside the feeding rotating bracket 108. A limiting sliding sleeve 110 is slidably connected to the outer side of the limiting sliding rod 109. A limiting spring 111 is fixedly installed at the bottom of the limiting sliding sleeve 110. A feeding rotating rod 112 is rotatably connected to the top of the limiting sliding sleeve 110. A feeding baffle 113 is rotatably connected to the top of the feeding rotating rod 112. First connecting hinges 114 are symmetrically installed at the top of the feeding baffle 113. A feeding box 115 is rotatably connected to the top of the two first connecting hinges 114. By vibrating the vibrating screening mesh 210 up and down, the support spring 105 and one first meshing rack 104 are driven to move up and down. Using the characteristic that the first meshing rack 104 is meshed and connected to the rotating gear 103, the other first meshing rack 104 drives the connecting support rod 106 to descend. Under the action of the sliding connection between the limiting sliding rod 109 and the limiting sliding sleeve 110 inside the feeding rotating bracket 108, while the feeding rotating bracket 108 rotates, the feeding rotating rod 112 is driven to rotate. The rotation of the feeding box 115 can be realized by using the first connecting hinge 114. By adjusting the rotation angle of the feeding box 115, the amount of material fed can be controlled, so that the material can be evenly distributed on the vibrating screening mesh 210. When there is more material on the vibrating screening mesh 210, due to the action of gravity, the descending amplitude of the vibrating screening mesh 210 is smaller. Under the action of the meshing connection between the rotating gear 103 and the first meshing rack 104, the unfolding amplitude of the feeding baffle 113 is smaller, so the feeding amount is less. When there is less material on the vibrating screening mesh 210, due to the action of gravity, the descending amplitude of the vibrating screening mesh 210 is larger. Therefore, the unfolding amplitude of the feeding baffle 113 is larger, so the feeding amount is more. The feeding amount of the feeding box 115 can be automatically adjusted according to the amount of material on the vibrating screening mesh 210, and the phenomenon of accumulation and blockage of the vibrating screening mesh 210 caused by more material will not occur. At the same time, the problem of affecting the screening efficiency of the vibrating screening mesh 210 due to less material will not occur.

By starting the mixing motor 117 to drive the mixing rotating rod 118, the mixing connecting rod 119 and the mixing plate 120 to rotate, the materials inside the blanking box 115 can be stirred, preventing the phenomenon of material accumulation and agglomeration, which may affect the amount of material blanking. When the vibrating screening mesh 210 needs to be automatically cleaned, the cleaning water pump 122 is controlled by an external controller to pump the cleaning water out of the cleaning water tank 121 and sprinkle it on the vibrating screening mesh 210 through the cleaning spray nozzles 123, thereby automatically cleaning the vibrating screening mesh 210.

[0021] Please refer to Figure 1 , Figures 7-10, the vibrating screening mechanism 2 includes a screening box 201.

The output end of the cleaning motor 212 is fixedly connected to a first sprocket transmission assembly 213. Cleaning threaded rods 214 are symmetrically installed on one side of the first sprocket transmission assembly 213. Cleaning threaded sleeves 215 are threadedly connected to the outer sides of the cleaning threaded rods 214. A meshing gear 216 is rotatably connected to one side of the cleaning threaded sleeve 215.

Under the elastic force of the screening spring 205 and the vibration spring 209, the vibration of the vibration screening mesh 210 can be realized, so as to screen the materials. When it is necessary to clean the vibration screening mesh 210, the cleaning motor 212 is started to drive the first sprocket transmission assembly 213 and the cleaning threaded rod 214 to rotate, so that the cleaning threaded sleeve 215 drives the meshing gear 216 and the cleaning roller 217 to move. By using the characteristic of meshing connection between the meshing gear 216 and the second meshing rack 218, the reverse rotation of the cleaning roller 217 can be realized, which is convenient for cleaning impurities and dust to the discharge port of the screening box 201. By starting the electric telescopic rod 219 to drive the second meshing rack 218 to move up and down, the meshing and separation of the second meshing rack 218 and the meshing gear 216 can be realized, and the rotation and stop of the cleaning roller 217 can be realized, which is convenient for cleaning the vibration screening mesh 210.

[0022] Please refer to Figures 10-11, on one side of the top of the inclined base 221, second connecting hinges 222 are symmetrically installed. The second connecting hinges 222 are rotatably connected to the screening box 201. On one side of the inclined base 221, a second sprocket limiting cover 223 is fixedly installed. On one side inside the second sprocket limiting cover 223, an inclined motor 224 is fixedly installed.

The top of the inclined rotating support plate 229 is rotatably connected to a second rotating bracket 230. The second rotating bracket 230 is fixedly installed on one side of the bottom of the screening box 201. By starting the inclined motor 224 to drive the second sprocket transmission assembly 225 and the inclined threaded rods 226 to rotate, the inclined threaded sleeve 227 moves on the outer side of the inclined threaded rod 226 while driving the first rotating bracket 228 and the inclined rotating support plate 229 to rotate. Under the action of the second rotating bracket 230 and the second connecting hinge 222, the inclination of the screening box 201 can be realized. By appropriately inclining the screening box 201, it is convenient to screen the materials and improve the screening effect of the materials.

[0023] Working principle: Before using this linear vibrating screen with self-cleaning function, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, the screening vibrating motor 207 drives the screening box 201 to vibrate. Under the elastic force of the screening spring 205 and the vibrating spring 209, the vibrating screening mesh 210 can be vibrated to screen the materials. When it is necessary to clean the vibrating screening mesh 210, start the cleaning motor 212 to drive the first sprocket transmission assembly 213 and the cleaning threaded rod 214 to rotate, so that the cleaning threaded sleeve 215 drives the meshing gear 216 and the cleaning roller 217 to move. By using the meshing connection between the meshing gear 216 and the second meshing rack 218, the reverse rotation of the cleaning roller 217 can be realized, which is convenient for cleaning impurities and dust to the discharge port of the screening box 201. By starting the electric telescopic rod 219 to drive the second meshing rack 218 to move up and down, the meshing and separation between the second meshing rack 218 and the meshing gear 216 can be realized, and the rotation and stop of the cleaning roller 217 can be realized, which is convenient for cleaning the vibrating screening mesh 210. By starting the tilting motor 224 to drive the second sprocket transmission assembly 225 and the tilting threaded rod 226 to rotate, the tilting threaded sleeve 227 moves on the outside of the tilting threaded rod 226 and drives the first rotating bracket 228 and the tilting rotating support plate 229 to rotate at the same time. Under the action of the second rotating bracket 230 and the second connecting hinge 222, the screening box 201 can be tilted. By appropriately tilting the screening box 201, it is convenient for screening materials and improves the screening effect of materials.

[0024] Secondly, the up and down vibration of the vibrating screening mesh 210 drives the support spring 105 and the first meshing rack 104 on one side to move up and down. By using the meshing connection between the first meshing rack 104 and the rotating gear 103, the first meshing rack 104 on the other side drives the connecting support rod 106 to descend. Under the action of the limit sliding rod 109 and the limit sliding sleeve 110 slidingly connected inside the blanking rotating bracket 108, the blanking rotating bracket 108 rotates and drives the blanking rotating rod 112 to rotate at the same time. By using the first connecting hinge 114, the rotation of the blanking box 115 can be realized. By adjusting the rotation angle of the blanking box 115, the amount of material discharged can be controlled, so that the materials can be evenly distributed on the vibrating screening mesh 210. When there is more material on the vibrating screening mesh 210, due to the action of gravity, the descending amplitude of the vibrating screening mesh 210 is smaller. Under the action of the meshing connection between the rotating gear 103 and the first meshing rack 104, the unfolding amplitude of the blanking baffle 113 is smaller, so the amount of material discharged is less. When there is less material on the vibrating screening mesh 210, due to the action of gravity, the descending amplitude of the vibrating screening mesh 210 is larger, so the unfolding amplitude of the blanking baffle 113 is larger, and the amount of material discharged is more. The discharging amount of the blanking box 115 can be automatically adjusted according to the amount of material on the vibrating screening mesh 210, and the phenomenon of accumulation and blockage of the vibrating screening mesh 210 caused by too much material will not occur. At the same time, the problem of affecting the screening efficiency of the vibrating screening mesh 210 due to too little material will not occur.

[0025] Finally, by starting the mixing motor 117 to drive the mixing rotating rod 118, the mixing connecting rod 119 and the mixing plate 120 to rotate, the materials inside the blanking box 115 can be stirred to avoid the phenomenon of material accumulation and agglomeration, thus affecting the amount of material blanking. When the vibrating screening mesh 210 needs to be automatically cleaned, the external controller controls the cleaning water pump 122 to pump the cleaning water out of the inside of the cleaning water tank 121 and sprinkle it on the vibrating screening mesh 210 through the cleaning nozzle 123, so as to automatically clean the vibrating screening mesh 210.
