Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen assembly for an automatic feeding vibrating screen. Background Technology

[0002] Vibrating screens are widely used screening equipment in industries such as mining, metallurgy, chemicals, building materials, and food. They are mainly used for grading, removing impurities, and dewatering materials. Their working principle involves using vibration to move the material on the screen surface, thereby achieving material stratification and separation.

[0003] A vibrating screen uses the excitation force generated by a vibrator to vibrate the screen box. The material on the screen surface is subjected to vibration, constantly jumping and sliding along the screen surface. Smaller particles fall through the screen mesh, while larger particles remain on the screen surface and continue to move forward, thus achieving material classification and separation.

[0004] The vibrator is a key component of a vibrating screen. Its main function is to generate vibration, causing the screen box to produce the required vibrational motion, thereby achieving material screening. A vibrating motor is a special type of motor that converts the rotational motion of a motor into linear or circular vibration. A vibrating motor typically consists of two eccentric blocks mounted at both ends of the motor shaft.

[0005] However, existing vibrating screens usually require manual feeding of materials for screening, which may lead to reduced work efficiency. Therefore, this method does not meet the current needs. To address this, we propose an automatic feeding vibrating screen component. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example aims to address the problem that existing vibrating screens typically require manual material feeding for screening, which can lead to reduced work efficiency. Please refer to [link to example]. Figures 1-4 A vibrating screen assembly for an automatic feeding vibrating screen includes a conveyor belt 110, a screening plate 111, and a vibrator 112. A support frame 134 is installed on the conveyor belt 110, and a fixed plate 113 is installed on the top of the support frame 134. The screening plate 111 is located at the bottom of the fixed plate 113. The screening plate 111 includes a first screening plate 114 and a second screening plate 115. The second screening plate 115 is located on the bottom side of the first screening plate 114. A first connecting plate 116 is installed between the first screening plate 114 and the second screening plate 115. The vibrator 112 is installed on the first screening plate 114, and a drive rod 117 is installed at the end of the vibrator 112. A driving rod 118 is installed on the second screening plate 115. A synchronization plate 119 is sleeved on the drive rod 117 and the driving rod 118. A feeding box 120 is installed on the side of the conveyor belt 110, and a feeding assembly 121 is provided between the feeding box 120 and the conveyor belt 110.

[0025] The feeding assembly 121 includes a feeding belt 122 installed in the feeding box 120. Several feeding plates 123 are installed on the feeding belt 122. A support plate 124 is installed on the side of the feeding belt 122. The bottom of the support plate 124 is fixedly installed in the feeding box 120. A control rod 135 and a driven rod 136 for driving the feeding belt 122 are inserted into the support plate 124. The control rod 135 is located above the driven rod 136. A drive motor 125 is connected to the end of the control rod 135.

[0026] The feeding plate 123 is set as an inclined plate, and the fixed plate 113 has an inlet 126. The inlet 126 is located on the upper side of the first screen plate 114 and is set as a funnel-shaped opening. A limiting plate 127 is installed on the fixed plate 113 and is located outside the inlet 126.

[0027] First fixing blocks 128 are installed on the sides of both the first sieve plate 114 and the second sieve plate 115, and the first fixing blocks 128 fix both ends of the first connecting plate 116. Second fixing blocks 129 are installed on the bottom of the fixing plate 113 and the side of the first sieve plate 114, and the second fixing blocks 129 are located on the side of the first fixing blocks 128. A second connecting plate 130 is installed between the second fixing blocks 129.

[0028] The material is first placed in the feeding box 120. The feeding belt 122 in the feeding box 120 is driven by the drive motor 125. The control rod 135 and the driven rod 136 work together to move several feeding plates 123 on the feeding belt 122. The feeding plates 123 are designed as inclined plates to facilitate the upward movement of the material in the feeding box 120. As the feeding plates 123 move, the material is gradually conveyed to the inlet 126 on the fixed plate 113. The material enters the first screen plate 114 through the funnel-shaped inlet 126 on the fixed plate 113. The limiting plate 127 restricts the flow of material to ensure that the material can smoothly enter the screening plate 111.

[0029] The material first falls onto the first screen plate 114. The first screen plate 114 and the second screen plate 115 are connected by a first connecting plate 116, with the second screen plate 115 located on the underside of the first screen plate 114. A vibrator 112 mounted on the first screen plate 114 provides vibration via a drive rod 117. The drive rod 117 and the driving rod 118 are connected by a synchronization plate 119 to ensure that the first screen plate 114 and the second screen plate 115 vibrate synchronously. The vibration of the vibrator 112 causes the material to undergo preliminary screening on the first screen plate 114, with smaller particles falling through the screen holes of the first screen plate 114 into the second screen plate 115. The second screen plate 115 further screens the material, ultimately separating it into different particle size grades. First fixing blocks 128 are installed on the sides of both the first screen plate 114 and the second screen plate 115 to fix both ends of the first connecting plate 116, ensuring the stability and connection strength of the screening plate 111.

[0030] Second fixing blocks 129 are installed at the bottom of the fixing plate 113 and on the side of the first screen plate 114. The second fixing blocks 129 are connected by a second connecting plate 130, further enhancing the overall structural stability of the vibrating screen assembly. After screening, the material is discharged from below the first screen plate 114 and the second screen plate 115 onto the conveyor belt 110 according to its particle size. The material is then moved along the conveyor belt 110 to the next process step. When the material remaining on the first screen plate 114 and the second screen plate 115 accumulates to a certain extent, it can be manually swept off.

[0031] In this embodiment: the feeding component 121 enables the material to be continuously and evenly conveyed to the vibrating screen without manual intervention, greatly improving work efficiency and ensuring the stability and continuity of material transmission. The first screen plate 114 and the second screen plate 115 enable the material to undergo two screenings, which not only improves screening efficiency but also allows for more accurate classification of the material by particle size. The clever connection between the vibrator 112 and the screen plate ensures more uniform vibration during the screening process, further improving the screening quality.

[0032] Example 2 aims to address the issue of displacement or loosening of the support plate 124 during operation. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-4 A mounting block 131 is installed on the side of the support plate 124 near the fixed plate 113. The fixed plate 113 has a mounting groove 132 corresponding to the mounting block 131, and the mounting block 131 engages with the mounting groove 132. A buffer strip 133 is installed in the mounting groove 132; the buffer strip 133 is a rubber strip. The holes in the first screen plate 114 are larger than those in the second screen plate 115. This ensures that the material is progressively graded according to particle size during the screening process of the first screen plate 114 and the second screen plate 115. The first screen plate 114 is mainly used for preliminary screening, retaining larger particles on the screen plate, while smaller particles fall through the screen holes into the second screen plate 115. The second screen plate 115 further refines the screening, ensuring more accurate final material grading.

[0033] In this embodiment: by installing mounting block 131 on the side of support plate 124 near fixed plate 113, and opening mounting groove 132 in fixed plate 113 corresponding to mounting block 131, the connection stability between support plate 124 and fixed plate 113 is enhanced, ensuring that the connection between feeding assembly 121 and vibrating screen assembly is firm and reliable. The buffer rubber strip 133 can effectively reduce the direct impact of vibration on fixed plate 113, avoid energy loss during vibration transmission, and reduce the impact of vibration on the overall structure.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
