Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, and more specifically, to an electric control vibration screening device. Background Art

[0002] The electric control vibration screening device is a material processing equipment widely used in many fields such as industry, mining, agriculture, food processing, chemical industry, and environmental protection. Its main function is to separate materials according to particle size through mechanical vibration, realizing the screening and grading of materials. The electric control vibration screening device mainly consists of a screening box, a screening mesh, a vibrator, a support system, and a control system. During operation, the control system controls the power of the vibrator to make the vibrator generate vibration, prompting the screening box to vibrate at a certain frequency and amplitude. The materials are thrown up and down in the screening box. Large particle materials remain on the screening mesh due to gravity, while small particle materials pass through the screening holes, realizing the grading of materials. Since the feeding during the screening process of the screening mesh directly affects the screening effect of the materials, it is necessary to perform screening material control operations on the materials.

[0003] In the related art, during the use of the screening device, generally, materials are added into the interior of the screening box through a feeding hopper to contact the screening mesh, and the screening mesh vibrates and screens the materials for use.

Therefore, the use flexibility of the material control plate 5 is improved.

[0033] Refer to Figure 3, in a preferred embodiment, positioning grooves 13 are provided on both sides of the front side of the inner wall of the force application port 6. A plurality of positioning grooves 13 are provided, and the plurality of positioning grooves 13 are equidistantly distributed.

Therefore, the force application effect and stability of the force application rod 7 are improved.

[0034] Referring to Figure 4 , in a preferred embodiment, stabilizing ports 17 are provided at both the top and bottom of the front side of the moving plate 9. A stabilizing frame 18 is movably connected inside the stabilizing ports 17, and the rear side of the stabilizing frame 18 is in contact with the inner wall of the moving port 8. When the moving plate 9 is used in cooperation with the moving port 8, a medium for positioning and stabilizing between the moving plate 9 and the moving port 8 can be provided for the user, avoiding the situation that it is difficult to position and stabilize the moving plate 9 during use.

One end of the spring 22 is fixedly connected to the inner wall of the limit frame 19, and the other end of the spring 22 is fixedly connected to the surface of the limit block 20. When the limit block 20 is used in cooperation with the stabilizing frame 18, the stabilizing frame 18 can be forced to disengage through the limit block 20, avoiding the situation that the stabilizing frame 18 disengages from the moving port 8 during operation. Therefore, the positioning stability effect of the stabilizing frame 18 is improved. A connecting sleeve 23 is fixedly connected to the bottom of the moving plate 9. A connecting seat 24 is rotatably connected inside the connecting sleeve 23. The rear side of the connecting seat 24 is fixedly connected to the front side of the screening box 1. When the moving plate 9 is used in cooperation with the moving port 8, rotational connection work can be carried out between the moving plate 9 and the moving port 8, avoiding the situation that the moving plate 9 separates from the screening box 1 during use. Therefore, the connection effect between the moving plate 9 and the screening box 1 is improved.

[0036] Specifically, the working process or working principle of this kind of electric-controlled vibrating screening device is as follows: when in use, according to the actual screening needs of the material, the hand-held force-applying rod 7 drives the positioning block 14 to move forward to disengage from the positioning groove 13 and enter the moving port 8. At this time, the tension spring 16 is affected by the moving force of the force-applying rod 7 and extends forward to prepare for the subsequent application of tension to the force-applying rod 7 and the positioning block 14, and applies an upward moving force to the material control plate 5 through the force-applying rod 7 and the force-applying groove 15, and adjusts the material moving space between the material control frame 4 and the screening net 3 so that the distance between the bottom of the material control plate 5 and the top of the screening net 3 meets the material The lifting slot 10 provides lifting and moving space for the material control plate 5. At the same time, the connecting column 12 cooperates with the connecting hole 11 to stabilize and reinforce the connection between the material control plate 5 and the material control frame 4 during the lifting and moving process. When the position adjustment of the material control plate 5 is completed, the hand-held force rod 7 drives the positioning block 14 to move to the rear side, so that the positioning block 14 enters the positioning slot 13 and cooperates with the force rod 7 to perform material control positioning between the material control plate 5 and the material control frame 4. At the same time, the tension spring 16 applies tension to the positioning block 14 through the force rod 7 to ensure the working stability of the positioning block 14 and the force rod 7. Then, the hand-held pull cylinder 2 1 drives the stabilizing frame 18 to be pulled forward, and the rear side of the stabilizing frame 18 is pulled to the inside of the stabilizing opening 17. At this time, the limit block 20 follows the stabilizing frame 18 to move inside the limit frame 19, and the stabilizing frame 18 and the movable plate 9 are limited. At the same time, the spring 22 is contracted by the moving force of the limit block 20, and is prepared for the subsequent application of thrust to the stabilizing frame 18 through the limit block 20. Then, the pull cylinder 21 cooperates with the limit frame 19 to flip the movable plate 9 to the front side of the movable opening 8. At this time, the connecting seat 24 rotates inside the connecting sleeve 23 to perform the rotation connection work between the movable plate 9 and the screening box 1. When the movable plate 9 is moved, the movable plate 9 is rotated to the front side of the movable opening 8. After the plate 9 is aligned with the moving port 8, the pull cylinder 21 is moved backward to push the stabilizing frame 18 into the moving port 8 to perform positioning and stabilizing work between the moving plate 9 and the moving port 8. At this time, the spring 22 applies a thrust to the stabilizing frame 18 through the limit block 20, so that the stabilizing frame 18 stabilizes the positioning and stabilizing work between the moving plate 9 and the moving port 8. When the screening box 1 and the screening net 3 are working, after the external material enters through the feed hopper at the top of the screening box 1, the material control frame 4 cooperates with the material control plate 5 to limit the screening space of the material, so that the material passes through the bottom of the material control frame 4 with a certain screening amount and fully contacts with the screening net 3 for uniform screening.

[0037] It should be noted that the screening box 1 and the vibration motor 2 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
