Description

Technical Field

This type of equipment occupies a large space, is noisy, and the rolling process is prone to adhesion of the materials due to the presence of anti-rust oil, resulting in incomplete screening and low separation efficiency. Utility Model Content

[0008] Furthermore, the screen holder includes a frame for limiting the installation of the screen.

[0009] Furthermore, the waste outlet trough is located on the side wall of the vibrating box near the lower inclined end of the vibrating motor.

[0010] Furthermore, the vibration motor is mounted at a 45° angle at the bottom of the vibration box via a bracket; an equilateral triangular structure is welded and fixed at the bottom center of the vibration box, and the vibration motor is mounted on the inclined plate.

[0011] Furthermore, the screening tray is a square frame with handles installed on both ends.

[0012] Furthermore, pins with a diameter smaller than the inner diameter of the damping spring are welded to the four corners of the bottom of the vibration box to limit and fix the damping spring.

[0019] like Figure 1 As shown, this embodiment provides a small vibrating screen for screening metal scrap, including a support frame, a vibrating box 1 mounted on the support frame by multiple damping springs 3, a screening mesh bracket 2 mounted at the bottom of the vibrating box 1, a screen 201 mounted on the screening mesh bracket 2, and a vibrating motor 5 mounted at the bottom of the vibrating box 1; wherein the top of the vibrating box 1 is an open structure, and a waste outlet groove 4 is provided on the side wall of the vibrating box 1; the waste outlet groove 4 is lower than the bottom surface of the screen 201 to prevent waste and metal scrap from being directly separated without screening; the vibrating motor 5 is installed at an angle at the bottom of the vibrating box 1 by a bracket; wherein when the vibrating motor is installed at an angle, it will generate vertical vibration along the vertical axis and rotational vibration around the vertical axis, thereby facilitating the screening components inside the vibrating box 1 to perform screening.

[0020] In this embodiment, the support frame is a base trolley 6; the base trolley 6 includes a base plate, locking casters installed at the bottom of the base plate, a push handle inclinedly connected to the base plate, and four support columns installed on the base plate; the tops of the four support columns are respectively equipped with damping springs 3 for connecting the vibration box 1; the locking casters are specifically locking casters, so as to lock and position them as needed.

[0021] In practice, the push handle is a U-shaped push rod welded to one side of the base trolley, facilitating the movement of the base trolley as needed. Furthermore, pins with a diameter smaller than the inner diameter of the damping spring 3 are welded to the four corners of the bottom of the vibration box 1 to limit and fix the damping spring.

[0022] In this embodiment, the screen holder 2 includes a frame for limiting the installation of the screen 201. The screen 201 has a square structure and handles at both ends for easy placement and removal by the operator.

[0023] The waste outlet trough 4 is located on the side wall of the vibrating box 1 near the lower inclined end of the vibrating motor 5; the vibrating motor 5 is mounted at the bottom of the vibrating box 1 at a 45° angle via a bracket.

[0024] During operation, the metal mixture is collected by the screen 201 and placed on the screen holder 2 inside the vibrating box 1. The vibration motor 5 is turned on, causing the vibrating box 1 to vibrate. The metal scrap on the screen 201 falls off, while larger metal pieces remain on the vibrating box 1, thus achieving rapid separation of the metal pieces and the scrap. The scrap that is screened out rolls out through the scrap outlet trough 4 on the side wall of the vibrating box 1. Typically, a scrap collection box is placed below the scrap outlet trough 4. Figure 1 (Not shown in the image). The base trolley 6 is fixed in the field by brake wheels, while the vibration box 1 and the base trolley 6 are connected by vibration damping springs 3 around the perimeter, which provides good vibration damping and reduces noise.

[0025] The working principle of this utility model is as follows: Figure 1 As shown, the vibration motor 5 is installed at the bottom of the vibration box 1 at a 45-degree angle via a bracket, so as to drive the vibration box 1 to generate an upward force, causing the vibration box 1 to vibrate back and forth, thereby driving the screen 201 to throw the metal mixture obliquely up. At this time, the metal waste falls from the screen holes of the screen 201 to the bottom of the vibration box 1 due to gravity. Due to the upward vibration force, the metal waste is vibrated towards the waste outlet trough 4 and falls from the waste outlet trough 4 into the waste collection box, completing the screening.

[0026] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
