Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a vibrating screen. Background Technology

[0002] As is well known, a vibrating screen works by utilizing the reciprocating rotary vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two forces causes the screen surface to produce complex rotary vibration.

[0003] Most existing vibrating screens have open ends, which makes it inconvenient to retain materials and ensure that the materials are fully screened. This makes them inconvenient to use and also inconvenient to transfer materials. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a vibrating screen.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen, comprising a frame, a screening assembly, and a protective assembly. The screening assembly includes a base frame, a collecting frame, a top frame, a filtering frame, a fixing seat, and a spring. The collecting frame and the base frame are mounted on the frame. The base frame is disposed around the collecting frame, and a top frame is also disposed above the collecting frame. Fixing seats are disposed at the four corners of the top frame and the four corners of the base frame. The spring is disposed between two sets of fixing seats arranged vertically and vertically. The filtering frame is also disposed on the top frame. The top frame is U-shaped and inclined. The side opening of the top frame is located at the lower end. A protective assembly is also disposed on the top frame near the side opening. A vibrating motor is also disposed on the side wall of the top frame away from the side opening.

[0008] To facilitate material transfer, this utility model is improved by having the collection frame in the shape of a frustum with a narrowed bottom, and a collection cover is also provided below the collection frame.

[0009] To ensure that the material remains stably on the filter frame of the top frame, this utility model is improved by including a guide frame, an insert plate, a support frame, a lifter, and a connecting plate. The left and right side walls of the top frame are also provided with support frames, and the left and right side walls of the top frame are symmetrically provided with guide frames adapted to the insert plate. The lifter passes through the center of the top wall of the top frame and is connected to one end of the connecting plate, and the other end of the connecting plate is connected to the top wall of the insert plate.

[0010] Preferably, the lifting device is a cylinder.

[0011] Preferably, a ladder is also provided on one side of the frame.

[0012] Preferably, a transfer tube is also provided at the side opening of the collection frame.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a vibrating screen with the following advantages:

[0015] The vibrating screen has a protective component to prevent material from being discharged from the opening in the top frame. The filter frame is located on the top frame. When the vibrating motor is started, a spring is installed between the fixed seat below the top frame and the fixed seat on the base frame of the machine frame. As the filter frame and the top frame vibrate, the material passes through the screen and falls into the collection frame. With the help of the transfer pipe, the material can pass through the screen and be transferred stably. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4A vibrating screen includes a frame 1, a screening assembly, and a protective assembly. The screening assembly includes a base frame 2, a collection frame 3, a top frame 4, a filter frame 5, a fixing seat 6, and a spring 7. The collection frame 3 and the base frame 2 are mounted on the frame 1. The base frame 2 is located around the collection frame 3. The top frame 4 is also mounted above the collection frame 3. Fixing seats 6 are mounted at the four corners of the top frame 4 and the four corners of the base frame 2. The spring 7 is positioned between two sets of fixing seats 6 arranged vertically. The filter frame 5 is also mounted on the top frame 4. The top frame 4 is U-shaped and inclined. The side opening of the top frame 4 is located at the lower end. A protective assembly is also mounted on the top frame 4 near the side opening. A vibrating motor 8 is also mounted on the side wall of the top frame 4 away from the side opening.

[0023] The frame 1 provides stable support for the base frame 2. The fixed seat 6 of the base frame 2 and the fixed seat 6 of the top frame 4 are connected by a spring 7. When the vibration motor 8 is started, the top frame 4 vibrates. A filter frame 5 is also provided on the top frame 4 to facilitate the screening of materials. When the top frame 4 screens, the protective components provide good protection to ensure that the unqualified materials are transferred after the materials are completely screened. The screened materials fall into the collection frame 3.

[0024] In this embodiment, the collection frame 3 is a frustum shape with a narrower opening at the bottom. A collection cover 9 is also provided below the collection frame 3. The upper opening of the collection frame 3 is larger, and the lower opening of the collection frame 3 is smaller, which facilitates centralized collection of materials.

The other end of the connecting plate 14 is connected to the top wall of the insert plate 11. The support frame 12 is set on the top frame 4. When no material is discharged, the lifter 13 drives the connecting plate 14 to move downward. The connecting plate 14 is connected to the insert plate 11 inserted into the guide frame 10 of the top frame 4, closing the side opening of the top frame 4 and ensuring the stable retention of the mixed material on the filter frame 5. In this embodiment, the lifter 13 adopts a stable cylinder.

[0026] In this embodiment, a ladder 15 is also provided on one side of the frame 1 to facilitate stable feeding, and a transfer pipe 16 is also provided at the side opening of the collection frame 3 to facilitate the transfer of larger materials.
