Description

Technical Field

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

[0002] A vibrating screen is a mechanical device used for separating, classifying, and screening granular materials. It generates vibration through a vibrating motor or exciter, causing the material to move on the screen surface, thereby achieving the separation of materials of different particle sizes. During operation, protective devices are required to prevent material from falling directly onto the screen and damaging it.

[0003] According to the description in the patent application CN 222287919 U, "This utility model discloses a vibrating screen protection device, which relates to the field of vibrating screen technology. It aims to solve the problem that the screen of the existing vibrating screen is easily damaged by the impact of the material during feeding. It includes a vibrating screen body, a top plate on the rear top of the vibrating screen body, a feeding hopper on the top plate, an upper guide plate and a lower guide plate hinged in the vibrating screen body, a connecting rod hinged between the upper guide plate and the lower guide plate, and a spring support mechanism between the bottom of the lower guide plate and the vibrating screen body. This utility model, by setting the upper guide plate, the lower guide plate and the connecting rod, allows the material to enter the screen through the guidance of the double-layer guide plate, reducing the falling angle of the material during feeding and reducing the force of direct impact on the screen, thereby effectively protecting the screen located at the feeding position, effectively reducing production costs, improving production efficiency and equipment service life. At the same time, the spring support mechanism can realize the automatic reset of the lower guide plate, so that the material falls completely into the vibrating screen and ensures that the material is fully screened."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model uses two guide plates to buffer the material. However, in actual use, because the guide plate structure is used for feeding, the material slides on the guide plate, which can easily cause blockage. Therefore, it is necessary to improve the vibrating screen protection device to solve the above problems. Utility Model Content

[0034] The first protective component 41 includes a first inclined plate 411, which is slidably installed inside the body 1. A first sealing plate 412 is fixedly installed on both the front and back of the first inclined plate 411. A first connecting block 413 is fixedly installed on the outer side of the first sealing plate 412. A first fixing frame 414 is fixedly installed on both the front and back of the body 1.

[0035] Furthermore, the front and back of the body 1 are provided with through slots, and the first inclined plate 411 passes through the through slots to facilitate the sliding of the first inclined plate 411 through the body 1.

[0036] Furthermore, both the first sealing plate 412 and the first connecting block 413 are slidably installed inside the first fixed frame 414.

[0037] Furthermore, the second protective component 42 includes a second inclined plate 421, which is slidably installed inside the machine body 1.

[0038] Furthermore, through slots are provided on the front and back of the body 1, and the second inclined plate 421 passes through the through slots to facilitate the sliding of the second inclined plate 421 through the body 1.

[0039] Furthermore, both the second sealing plate 422 and the second connecting block 423 are slidably installed inside the second fixed frame 424.

[0040] Example 2:

[0041] To achieve driving and feeding of the first inclined plate 411 and the second inclined plate 421, please refer to... Figure 7 Furthermore, in conjunction with Embodiment 1, the vibration drive mechanism 5 includes a motor base 51, which is fixedly installed on the front and back of the machine body 1.

A synchronous belt 56 is installed between the two synchronous wheels 55 to facilitate driving the first inclined plate 411 and the second inclined plate 421 to vibrate.

[0042] Furthermore, the cam 54 outside the output end of the drive motor 52 contacts the second connecting rod 426, and the cam 54 outside the rotating rod 53 contacts the first connecting rod 416, so that the cam 54 can drive the second connecting rod 426 and the first connecting rod 416 to move.

[0043] In actual operation, when this device is in use, material is added from the feed hopper 2, and the material falls onto the first inclined plate 411, then onto the second inclined plate 421.
