Description

Technical Field

[0001] This utility model relates to the technical field of unloading funnels, and in particular to an automatic tilting windbreak wall for a negative pressure dust removal funnel, especially its mechanical connection structure. Background Technology

[0002] When the grab bucket and the unloading funnel work together to unload materials, the grab bucket is at a certain height from the funnel. Due to the nature of the material, the dust during the unloading process is particularly large, and the dust collector often cannot effectively achieve negative pressure dust removal. By increasing the internal depth of the unloading funnel, dust can be effectively controlled and the negative pressure dust removal effect can be improved. However, the unloading funnel is located at the dock. If the unloading funnel is designed to be too deep during typhoons, it will increase the windward surface of the unloading funnel and reduce its typhoon resistance.

[0003] Therefore, it is necessary to further improve the structure of the existing negative pressure dust removal funnel. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic tilting windbreak wall for a negative pressure dust removal funnel, which overcomes the shortcomings and deficiencies of the existing technology.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: It comprises a funnel body, with a first windbreak wall, a second windbreak wall, a third windbreak wall, and a fourth windbreak wall respectively provided on the upper edge of the funnel body. The first windbreak wall, the second windbreak wall, the third windbreak wall, and the fourth windbreak wall are hinged to the upper edge of the funnel body via pins. An installation platform is formed around the funnel body, and at least two first hydraulic cylinders, two second hydraulic cylinders, two third hydraulic cylinders, and two fourth hydraulic cylinders are respectively provided on the installation platform. Each of the first hydraulic cylinders, the second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder is fixed to the installation platform by a hydraulic cylinder support. Two symmetrically distributed ear plates are provided on the outer walls of each of the first, second, third, and fourth windbreak walls. The first windbreak wall is hinged to the end of the first hydraulic cylinder via the ear plate, the second windbreak wall is hinged to the end of the second hydraulic cylinder via the ear plate, the third windbreak wall is hinged to the end of the third hydraulic cylinder via the ear plate, and the fourth windbreak wall is hinged to the end of the fourth hydraulic cylinder via the ear plate. A frame is provided at the lower part of the funnel body.

[0006] This utility model discloses an automatic tilting windbreak wall for a negative pressure dust removal funnel, with the following technical effects:

[0007] 1. When the material unloading dust is particularly large, the four windbreak walls flip up and stand upright, the dust collector starts negative pressure dust removal, and the grab bucket is inserted into the funnel to unload the material, which greatly increases the dust removal effect.

[0008] 2. When the dust generated during material unloading is not particularly large, the seaside windbreak can be opened, and the grab bucket can be inserted parallel to the funnel. This can block the lift caused by the sea wind, increase the dust removal effect, and reduce the lifting height of the grab bucket, thereby improving unloading efficiency. At the same time, the seaside windbreak also acts as a material retainer, preventing materials from falling directly onto the dock surface, ensuring both safety and ground cleanliness.

[0009] 3. During typhoons, the four windbreak walls at the dock will flip down to reduce the windward side of the funnel and increase its typhoon resistance.

[0010] 4. It can automatically adjust to adapt to the unloading conditions of different species. Attached Figure Description
