Description

Technical Field

[0001] The utility model relates to the technical field of heavy mining equipment, in particular to a water truck water tank cover with a variable funnel. Background Art

[0002] The work of sprinkling dust suppression is an important part of mine production. At present, all the practical mine water trucks adopt a design without a top cover, so the water filling port cannot be designed too large, resulting in a lot of sundries entering the water tank during operation, causing damage to the sprinkler system. In addition, due to the small size of the water tank port, it increases the difficulty for the driver to align with the water crane. Frequently, due to incorrect alignment, there are serious running, dripping and leaking problems during the water filling process, wasting water resources and seriously affecting the use efficiency of the equipment, which is not conducive to the safety and environmental protection work of the mine. Content of the Utility Model

[0003] The purpose of the utility model is to provide a water truck water tank cover with a variable funnel and a water truck water tank to solve the problems existing in the above-mentioned prior art, which has a simple structure, is convenient to use, and effectively reduces the difficulty of aligning with the water crane.

[0004] To achieve the above purpose, the utility model provides the following scheme:

[0005] The utility model provides a water truck water tank cover with a variable funnel, including: four rigid covers and four telescopic members. One of the rigid covers is rotatably connected to one edge of a square water truck water tank opening. The rigid cover includes an isosceles trapezoidal plate and an isosceles triangular plate. The isosceles trapezoidal plate and the isosceles triangular plate are integrally connected. The short side of the isosceles trapezoidal plate is the base of the isosceles triangular plate. The short side of the isosceles trapezoidal plate is rotatably connected to the edge of the square water truck water tank opening. One end of the telescopic member is hinged to the top of the water tank, and the other end is hinged to the isosceles trapezoidal plate. When the four telescopic members synchronously extend, the four rigid covers can form a pyramidal funnel. When the four telescopic members synchronously contract and the rigid covers are laid flat, the four isosceles triangular plates can close the square water truck water tank opening.

[0006] Preferably, the telescopic member is an electro-hydraulic push rod.

[0007] Preferably, it further includes four flexible waterproof cloths. One of the flexible waterproof cloths is arranged between two of the isosceles trapezoidal plates.

[0008] Preferably, the flexible waterproof cloth is adhesively fixed to the isosceles trapezoidal plate.

[0020] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] The present utility model provides a water truck water tank mouth cover with a variable funnel, as Figures 1 to 3 shown, including: four rigid covers 1 and four telescopic members. One rigid cover 1 is rotatably connected to one edge of a square water truck water tank mouth 5. The rigid cover 1 includes an isosceles trapezoidal plate and an isosceles triangular plate, which are integrally connected. The short side of the isosceles trapezoidal plate is the base of the isosceles triangular plate, and the short side of the isosceles trapezoidal plate is rotatably connected to the edge of the square water truck water tank mouth 5. One end of the telescopic member is hinged to the top of the water tank 6, and the other end is hinged to the isosceles trapezoidal plate. Synchronous elongation of the four telescopic members can make the four rigid covers 1 form a pyramidal funnel. Synchronous contraction of the four telescopic members can make the rigid covers 1 lie flat, enabling the four isosceles triangular plates to close the square water truck water tank mouth 5. During the watering operation of the sprinkler truck, the telescopic members contract, and the four rigid covers 1 are laid flat on the top of the water tank 6. The four isosceles triangular plates close the water tank mouth 5 to prevent foreign objects from entering the water tank. When water needs to be added, the telescopic members extend, and the four rigid covers 1 form a quadrangular pyramidal funnel, increasing the area of the water filling port and effectively reducing the difficulty of aligning with the water crane.

[0023] In a preferred solution of this embodiment, the telescopic member is an electro-hydraulic push rod 4, which has a simple structure and convenient material selection.

[0024] In a preferred solution of this embodiment, the water truck water tank mouth cover with a variable funnel further includes four flexible waterproof cloths 2. One flexible waterproof cloth 2 is arranged between two isosceles trapezoidal plates. The flexible waterproof cloth 2 can prevent water from flowing out through the gaps of the rigid cover 1 during the water filling process, and all the water will flow back into the water tank under the action of gravity.

[0025] In a preferred solution of this embodiment, the flexible waterproof cloth 2 is fixedly bonded to the isosceles trapezoidal plate by glue, which has a simple structure.

[0026] In a preferred solution of this embodiment, the rigid cover 1 is rotatably connected to the edge of the square water truck water tank mouth 5 through a pin shaft structure 3, which has a simple structure and convenient material selection.

[0027] Embodiment 2

[0028] This embodiment also provides a water truck water tank, including the water truck water tank mouth cover with a variable funnel according to any one of Embodiment 1.

[0029] Embodiment 3

[0030] Working process: When the sprinkler is performing the sprinkling operation, the electro-hydraulic push rod 4 contracts, and the four rigid covers 1 are laid flat on the top 6 of the water tank, and the water tank opening 5 is closed to prevent foreign objects from entering the water tank. When water needs to be added, the electro-hydraulic push rod 4 extends, and the four rigid covers 1 form a quadrangular pyramid-shaped funnel to increase the area of the water filling port, and the flexible part contracts, which can effectively prevent water from spilling out from the connecting gaps of the rigid covers 1. Specific examples are applied in the present utility model to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
