Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screen equipment, and more specifically to a cleaning device for a linear vibrating screen. Background Art
[0002] Vibrating screen can screen and sort materials. The vibrating screen is equipped with a screen. The materials on the screen are screened by vibration, so that small-diameter materials fall under the screen and are discharged from the outlet below the vibrating screen, while large-diameter materials stay on the screen to achieve screening and sorting. Linear vibrating screen is a type of vibrating screen. It is rectangular, with stabilizing mechanisms installed on the four corners and a long strip of screen installed inside.
[0003] When in use, the screen is usually fixed to the inside of the linear vibrating screen by fasteners, so as to facilitate the maintenance and replacement of the screen, and also to facilitate the cleaning of the inside of the linear vibrating screen. When cleaning the inside of the vibrating screen, the screen will be removed from the inside of the vibrating screen. At this time, the solid particles stuck at the connection between the screen and the screen body and the particles stuck on the screen will fall into the inside of the vibrating screen, and manual cleaning is required. Since the linear vibrating screen is often used for screening powdery materials, it can only be cleaned with a brush to prevent the powder from sticking to the inner wall of the vibrating screen when it meets water. However, this not only increases the labor intensity, but also the dust raised during cleaning will affect the cleaning personnel and the environment.
[0004] Therefore, it is necessary to propose a cleaning device for a linear vibrating screen to solve the above problems. Utility Model Content

[0025] 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.
[0026] See also Figure 1-4, a cleaning device for a linear vibrating screen includes a vibrating screen 101, and the vibrating screen 101 is a linear vibrating screen 101. This is a mature device and will not be described in detail here. A cleaning device 102 is arranged inside the vibrating screen 101. At least one screen is arranged inside the vibrating screen 101. The cleaning device 102 is arranged at the bottom and contacts the bottom wall of the vibrating screen 101. When the vibrating screen 101 is stopped and the inside needs to be cleaned, the particles when the screen is removed will fall onto the bottom wall and can be cleaned by the back and forth movement of the cleaning device 102. A driving device 103 is arranged outside the vibrating screen 101. A transmission device 104 extending into the inside of the vibrating screen 101 is connected to the output end of the driving device 103. The driving device 103 is installed on the vibrating screen 101 and includes a symmetrical threaded rod. One end of the threaded rod is connected to the driving device 1 03 is connected to the output end, and the other end is transmission-connected to the cleaning device 102, and the transmission device 104 is transmission-connected to the cleaning device 102. A cleaning port that penetrates to the outside is opened at the bottom of the end of the vibrating screen 101 away from the discharge port. When the cleaning device 102 is cleaning, it will move from the end close to the driving device 103 toward the end of the discharge port, and the cleaning brush 107 at the bottom will sweep the particles on the bottom wall of the vibrating screen 101 toward the discharge port. Because the discharge port of the vibrating screen 101 is usually tilted to facilitate discharging, the particles will be discharged from the pipe of the discharge port after moving to the position of the discharge port. When the cleaning device 102 moves back, it will clean again. When it moves to the top of the cleaning port, the particles will fall from the cleaning port into the collection box 105 at the bottom. The bottom of the cleaning port is detachably connected with the collection box 105.
[0027] refer to Figure 3 and Figure 4 The cleaning device 102 is composed of a moving box 106, a cleaning brush 107 and a baffle 108. When the vibrating screen 101 is used for screening, the cleaning device 102 is close to the inner wall of the vibrating screen 101, and the baffle 108 is located at the bottom, so that the extrusion block 118 at the bottom is pressed into the extrusion groove 117, and the cleaning brush 107 is fixed to the bottom of the moving box 106. A cavity 109 is opened inside the moving box 106. A guide column 110 and a support plate 111 are fixedly connected to the bottom wall of the cavity 109. The guide column 110 is used to stabilize the up and down movement of the baffle 108. The support plate 111 makes the trigger block 112 extend outward through the spring 113. The two ends of the baffle 108 are slidably connected to the guide column 110, and a trigger block 112 is moved laterally in the cavity 109.
[0028] Specifically, when the cleaning device 102 has finished cleaning, the trigger block 112 will first come into contact with the inner wall of the vibrating screen 101, thereby being pressed into the cavity 109. At this time, the connecting rod 116 moves in the sliding groove 115, thereby driving the baffle 108 to move downward, so that the extrusion block 118 at the bottom is pressed on the extrusion groove 117, which is used to prevent the vibrating screen 101 from falling into the collecting box 105 from the cleaning port when the vibrating screen 101 is screening. A hole that penetrates the moving box 106 is provided on one side of the cavity 109 close to the driving device 103, and the trigger block 112 can extend out of the hole and contact the inner wall of the vibrating screen 101. A spring 113 is connected between the trigger block 112 and the support plate 111;
[0029] refer to Figure 3 and Figure 4 , a square plate 114 is connected to one side of the baffle 108 close to the trigger block 112, a sliding groove 115 is provided on the square plate 114, the sliding groove 115 is tilted, and the top is tilted toward the baffle 108, when the trigger block 112 moves out of the cavity 109, the connecting rod 116 slides in the sliding groove 115, which will drive the baffle 108 to move upward, and the top of the sliding groove 115 is set toward the baffle 108, and a connecting rod 116 is slidably connected in the sliding groove 115, one end of the connecting rod 116 is connected to the trigger block 112, and the other end is slidably connected in the sliding groove 115, and the other end of the connecting rod 116 is connected to the trigger block 112;
[0030] refer to Figure 2 and Figure 4 An extrusion groove 117 is provided on the side of the top of the cleaning port away from the driving device 103. When the extrusion block 118 is pressed on the extrusion groove 117, it will play a sealing role, which is used to block the material when the vibrating screen 101 is working. One side of the extrusion groove 117 is set as an inclined surface, and the bottom of the baffle 108 is connected to the extrusion block 118. The bottom of the extrusion block 118 corresponds to the extrusion groove 117 and the inclined surface. It should be noted that when the cleaning device 102 moves to the other end, the extrusion block 118 will slide obliquely in the extrusion groove 117 for a short distance, and then rise to the top. Because the extrusion block 118 is made of soft material, it will not affect the movement of the cleaning device 102.
[0031] Specifically, refer to Figure 4 The extrusion block 118 is made of a soft material, preferably rubber. An inclined surface is provided on the top of the extrusion block 118. When material falls on the top of the extrusion block 118, it will fall on the bottom wall of the vibrating screen 101 through the inclined surface and tilt toward the discharge port of the vibrating screen 101.
[0032] Specifically, refer to Figure 1 and Figure 2The transmission device 104 includes a chain, a symmetrical sprocket and a threaded rod. The sprocket is sleeved on one end of the threaded rod, and the chain is connected to the symmetrical sprocket. The output end of the driving device 103 is connected to one of the threaded rods. The driving device 103 drives the threaded rod on the transmission device 104 to rotate, thereby driving the cleaning device 102 to move and clean. The cleaning device 102 is transmission-connected to the threaded rod.
[0033] Specifically, the driving device 103 is fixedly connected to the outer wall of the vibrating screen 101 , and the driving device 103 is a servo motor.
[0034] In this embodiment, when the vibrating screen 101 is screening materials, the cleaning device 102 is located on one side of the inside of the vibrating screen 101, close to the side wall, and the extrusion block 118 is pressed on the extrusion groove 117, which blocks the material and prevents the material from entering the collection box 105 from the drop port. The screened material will be discharged from the discharge port at one end of the vibrating screen 101, thereby achieving the effect of screening the material.
[0035] When it is necessary to replace the screen inside the vibration screen 101, or to clean the inside of the vibration screen 101, first open the upper cover of the vibration screen 101, then the screen is exposed, and when the screen is taken out from the inside of the vibration screen 101, the solid particles in the gap will fall onto the bottom wall, and then start the driving device 103, the output end of the driving device 103 drives the threaded rod of the transmission device 104 to rotate, and drives the cleaning device 102 to move horizontally from one end to the other end, and when the moving box 106 moves, the cleaning brush 107 at the bottom can clean the bottom wall of the vibration screen 101 and push the solid particles to the discharge port, so as to clean the inside of the vibration screen 101;
[0036] When the cleaning device 102 returns, it can clean the bottom wall once more. When it moves to the top of the collection box 105, the particles will fall into the collection box 105, so that the maintenance personnel can collect and clean them.
[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
