Description

Technical Field

[0001] The utility model belongs to the technical field of concrete processing related equipment, in particular to a vibrating screen protective cover. Background Art

[0002] Currently, sand and gravel vibrating screens operate by utilizing the reciprocating vibrations generated by vibrator excitation. The vibrator's upper rotating weight causes the screen surface to produce planar gyratory vibrations, while the lower rotating weight causes the screen surface to produce conical gyratory vibrations. The combined effect of these vibrations produces compound gyratory vibrations on the screen surface. The use of sand and gravel vibrating screens is very convenient for concrete processing and has an excellent screening effect on sand and gravel. Current sand and gravel vibrating screens can meet their basic functional requirements, but in actual use, there are still some defects and deficiencies: the current protective covers generally cannot be flexibly adjusted to apply to vibrating screens of different sizes and lengths, and the current protective covers need to be removed during the conveying and unloading process, making them very troublesome to use. Utility Model Content

[0003] In order to solve the above-mentioned problems that the existing protective cover is generally unable to adapt to vibrating screens of various lengths and sizes, and the protective cover needs to be detached during the blanking process, the utility model provides a vibrating screen protective cover.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The present invention will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-4 As shown, the utility model provides a vibrating screen protective cover, including a protective outer cover 1 and a mounting plate 2, wherein two groups of mounting plates 2 are provided and the two groups of mounting plates 2 are relatively parallel. The protective outer cover 1 is a cover structure with openings on one side and the bottom side, and the two sides of the bottom end of the protective outer cover 1 are fixedly connected to the two groups of mounting plates 2. A telescopic inner cover 3 is movably provided in the protective outer cover 1, and the telescopic inner cover 3 is a cover structure with openings on the front, rear and bottom sides. Slide grooves 4 are provided on the bottom walls of the telescopic inner cover 3 on both sides, and slide rails 5 are provided on the mounting plate 2. The slide rails 5 are adapted to be slidably connected with the slide grooves 4. Protruding handles 15 extend laterally on both sides of the front port of the telescopic inner cover 3, which is convenient for sliding and adjusting the telescopic inner cover 3 through the protruding handles 15. The telescopic inner cover 3 slides on the slide rails 5 through the slide grooves 4, thereby telescopically sliding inside the protective outer cover 1 to adapt to vibrating screens of different lengths. Support blocks 6 are provided on both sides of the bottom end of the front opening of the telescopic inner cover 3. The support block 6 is an L-shaped structure, which is covered on the outer wall of the support block 6. A sealing plate 7 is installed on the support block 6. The anti-slip rubber layer of the support block 6 has a certain contact friction force on the sealing plate 7, and the supporting stability is better. After the protective outer cover 1 is installed on the vibrating screen through the mounting plate 2, the telescopic inner cover 3 is slid and adjusted to hold the vibrating screen cover, and then the sealing plate 7 is installed on the support block 6, which effectively prevents dust and sand from splashing when the vibrating screen is working. When it is necessary to unload the material to the vibrating screen, it is only necessary to pull the sealing plate 7 away from the support block 6, and then the telescopic inner cover 3 is retracted in the direction of the protective outer cover 1 to expose the vibrating screen, and then the unloaded material is transported to the vibrating screen. A positioning mechanism 8 is provided between the telescopic inner cover 3 and the protective outer cover 1. The positioning mechanism 8 can fix the position of the telescopic inner cover 3 and the protective outer cover 1 relatively, so as to prevent the telescopic inner cover 3 from being displaced due to vibration during the operation of the vibrating screen.

[0019] like Figure 1-4 As shown, the positioning mechanism 8 includes a positioning hole 9, a support block 10 and a positioning rod 11. The positioning holes 9 are uniformly arrayed laterally on the outer wall of the telescopic inner cover 3. The support block 10 is provided on the outer wall of the protective outer cover 1. The positioning rod 11 moves through the support block 10 and is plugged and adapted to the positioning hole 9. The positioning mechanism 8 also includes a limiting piece 12 and a spring 13. The limiting piece 12 is provided at the end of the positioning rod 11, and the spring 13 is sleeved on the positioning rod 11. One end of the spring 13 is connected to the limiting piece 12, and the other end of the spring 13 is connected to the support block 10. First, pull the limiting piece 12 to pull the positioning rod 11 out of the positioning hole 9. At this time, the spring 13 is in a compressed state. Then, the telescopic inner cover 3 is slidably adjusted. After the telescopic inner cover 3 is adjusted to a suitable position relative to the protective outer cover 1, the limiting piece 12 is released. Under the action of the reset elastic force of the spring 13, the positioning rod 11 is plugged into the corresponding positioning hole 9 to achieve fixation of the position of the telescopic inner cover 3.

[0020] like Figure 1 and 2 As shown, a vacuum cleaner 14 is installed on the outer wall of the protective outer cover 1 opposite to the sealing plate 7. The dust suction port of the vacuum cleaner 14 is placed on the inner side of the protective outer cover 1. The vacuum cleaner 14 absorbs the dust in the inner cavity of the cover formed by the protective outer cover 1, the telescopic inner cover 3 and the sealing plate 7 to prevent the dust from floating around and affecting the working environment.

[0021] When the cam 11 is in the closed position, the spring 13 is released, and the cam 12 is in the closed position, so that the cam 11 is in the closed position and the cam 12 is in the closed position.

[0022] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
