Description

Technical Field

[0001] This utility model relates to a screening device that facilitates classification, and belongs to the technical field of screening devices. Background Technology

[0002] A screening device is a piece of equipment used to separate materials of different particle sizes, widely used in industries such as mining, chemicals, and building materials. It uses vibration or rotation to cause the material to move on the screen surface, thus classifying it according to particle size differences. A screening device generally consists of a screen frame, screen mesh, vibration source, and motor, and can efficiently complete the screening, separation, and classification of solid particles. Based on different working principles, screening devices come in various types, such as vibrating screens, drum screens, and flat screens. Their main function is to improve production efficiency and optimize the material handling process.

[0003] In existing technology, screening devices typically use screens to screen materials. However, when materials fall from the hopper onto the screen surface, the inlet position cannot be changed, causing materials to easily accumulate in the same part of the screen, reducing the screen's utilization rate and potentially causing screen blockage, thus affecting screening efficiency.

[0004] Therefore, a screening device that facilitates classification is proposed. Utility Model Content

[0005] In view of this, the present invention provides a screening device that facilitates classification, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model is implemented as follows: A screening device for easy classification includes a screening box, a feed pipe connected to the middle of the top of the screening box, a guide pipe connected to the top of the feed pipe, a driven gear fixedly connected to the surface of the feed pipe, a servo motor fixedly connected to the left side of the top of the screening box, a drive gear fixedly connected to the output end of the servo motor, and the drive gear and the driven gear meshing through teeth, connecting plates fixedly connected to the left and right sides of the inner cavity of the screening box, a return spring fixedly connected to the top of the connecting plate, a screening screen fixedly connected to the top of the return spring, and a vibration motor provided at the middle of the bottom of the screening screen.

[0007] More preferably, the top of the screening box is provided with a dust cover, and the dust cover is threadedly connected to the screening box on all four sides by fastening screws.

[0008] More preferably, the surface of the feed pipe is provided with a connecting bearing, and the connecting bearing is connected to the inner wall of the screening box.

[0009] More preferably, guide plates are fixedly connected to both sides of the bottom of the screening box, and a discharge pipe is connected to the middle of the bottom of the screening box, and a solenoid valve is installed in the discharge pipe.

[0010] More preferably, the front side of the screening box is provided with a maintenance cover plate, and the maintenance cover plate is threadedly connected to the screening box by fastening screws on all four sides.

[0011] More preferably, the bottom of the screening box is fixedly connected to support legs on all four sides, and the bottom of the support legs is glued with rubber pads.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model uses the output end of a servo motor to drive the active gear to rotate. During the rotation of the active gear, the meshing of the teeth drives the driven gear to rotate. The driven gear ultimately drives the feed pipe to rotate in a circular motion, causing the material drop point of the feed pipe to rotate and change continuously, thereby dispersing the material to different parts of the screening screen, improving the utilization rate, and at the same time avoiding the clogging of the screening screen, thus improving the screening efficiency.

[0014] II. This utility model uses a vibrating motor to generate vibration, which drives the screening screen to vibrate. At this time, the vibration generated by the screening screen is transmitted to the surface of the return spring, causing it to deform repeatedly under the influence of force. Finally, the return spring transmits the force generated by the repeated deformation back to the surface of the screening screen, which can increase its vibration amplitude, thereby screening the material at the top of the screening screen, improving the screening effect and facilitating classification.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1-4 As shown, this utility model embodiment provides a screening device for easy classification, including a screening box 1, a feed pipe 3 connected to the middle of the top of the screening box 1, a guide pipe 4 connected to the top of the feed pipe 3, a driven gear 11 fixedly connected to the surface of the feed pipe 3, a servo motor 9 fixedly connected to the left side of the top of the screening box 1, a drive gear 10 fixedly connected to the output end of the servo motor 9, and the drive gear 10 and the driven gear 11 mesh with each other through teeth.

[0026] The output of the servo motor 9 drives the drive gear 10 to rotate. During the rotation of the drive gear 10, the meshing of the teeth drives the driven gear 11 to rotate. The driven gear 11 eventually drives the feed pipe 3 to rotate, so that the material drop point of the feed pipe 3 keeps rotating and changing, thereby dispersing the material to different parts of the screening screen 12, improving the utilization rate, and at the same time avoiding the clogging of the screening screen 12, thus improving the screening efficiency.

[0027] Example 2

[0028] In one embodiment, connecting plates 15 are fixedly connected to the left and right sides of the inner cavity of the screening box 1. A return spring 14 is fixedly connected to the top of the connecting plate 15. A screening screen 12 is fixedly connected to the top of the return spring 14. A vibration motor 13 is provided at the middle of the bottom of the screening screen 12. A dust cover 2 is provided on the top of the screening box 1. The dust cover 2 is threadedly connected to the screening box 1 by fastening screws on all four sides. A connecting bearing 17 is provided on the surface of the feed pipe 3. The connecting bearing 17 is connected to the inner wall of the screening box 1. A guide plate 16 is fixedly connected to both sides of the bottom of the inner cavity of the screening box 1. A discharge pipe 8 is connected to the middle of the bottom of the screening box 1. A solenoid valve 7 is provided in the discharge pipe 8. A maintenance cover 5 is provided on the front side of the screening box 1. The maintenance cover 5 is threadedly connected to the screening box 1 by fastening screws on all four sides. Support legs 6 are fixedly connected to all four sides of the bottom of the screening box 1. A rubber pad is adhered to the bottom of the support legs 6.

[0029] The vibration generated by the vibrating motor 13 drives the screening screen 12 to vibrate. At this time, the vibration generated by the screening screen 12 is transmitted to the surface of the return spring 14, causing it to deform repeatedly under the influence of force. Finally, the return spring 14 transmits the force generated by the repeated deformation to the surface of the screening screen 12 again, which can increase its vibration amplitude, thereby screening the material at the top of the screening screen 12, improving the screening effect and facilitating classification.

[0030] In operation, this invention works as follows: First, the material to be screened is poured into the screening box 1 through the guide pipe 4 and the feed pipe 3. At this time, the output end of the servo motor 9 drives the drive gear 10 to rotate. During the rotation of the drive gear 10, the driven gear 11 is driven to rotate through the meshing of the teeth. The driven gear 11 eventually drives the feed pipe 3 to rotate in a circular motion, so that the material landing point of the feed pipe 3 keeps rotating and changing, thereby dispersing the material to different parts of the screening screen 12, improving the utilization rate, and at the same time avoiding the clogging of the screening screen 12, thus improving the screening efficiency. Subsequently, the vibration motor 13 generates vibration to drive the screening screen 12 to vibrate. At this time, the vibration generated by the screening screen 12 is transmitted to the surface of the return spring 14, causing it to deform repeatedly under the influence of force. Finally, the return spring 14 transmits the force generated by the repeated deformation to the surface of the screening screen 12 again, which can increase its vibration amplitude, thereby screening the material at the top of the screening screen 12, improving the screening effect and facilitating classification.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
