Description

Technical Field

[0001] This utility model relates to a multi-angle coal yard spraying device. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground through complex biochemical and physicochemical changes. It is widely used, and during coal mining, processing, transportation, and use, it needs to be temporarily stored in coal yards. However, this storage process easily generates large amounts of coal dust, which not only wastes resources but also harms the environment. Current technologies mainly suppress dust by spraying water, but existing devices are difficult to adjust the spray angle and have a limited spray range, thus reducing the effectiveness of dust control to some extent. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a multi-angle coal yard spraying device.

[0004] To achieve the above objectives, this utility model provides a multi-angle coal yard spraying device, including a positioning frame disposed above the coal pile, and a spraying head and a spraying guide mechanism disposed at the lower part of the positioning frame;

[0005] The spray guiding mechanism includes a positioning bushing fixed to the positioning frame at the top, a lifting rod slidably disposed within the positioning bushing, a first connecting rod evenly installed along the circumferential direction at the lower outer periphery of the positioning bushing, a second connecting rod installed on the lower outer periphery of the lifting rod corresponding one-to-one with the first connecting rod, the two ends of the first connecting rod being hinged to the positioning bushing and one end of the second connecting rod respectively, the other end of the second connecting rod being hinged to the lifting rod, and a flexible guide cloth being installed between the first connecting rods to form an integrated structure, and the spray head being connected to the water inlet pipe through an auxiliary water pipe.

[0006] As a further improvement of this utility model, the upper part of the lifting rod is connected to a cylinder, and the cylinder is installed on the upper part of the positioning frame.

[0007] As a further improvement of this utility model, the spray head is provided in two or more sets, and the spray head is arranged symmetrically with the positioning bushing as the center.

[0008] As a further improvement of this utility model, the distance between the spray head and the positioning bushing is less than the length of the first connecting rod.

[0009] As a further improvement of this utility model, the flexible guide cloth is made of waterproof material.

[0010] The beneficial effects of this utility model are as follows:

[0011] In this device, spray heads are arranged around the circumference of the spray guide mechanism. The spray guide mechanism controls the opening angle of the first connecting rod and the flexible guide cloth through the lifting rod. The spray heads first spray water onto the flexible guide cloth, and then slide down along the flexible guide cloth and diffuse into the air to form a dust prevention and dust suppression effect. It is easy to operate and has a large angle adjustment range. Attached Figure Description

[0015] like Figure 1 As shown, the multi-angle coal yard spraying device of this utility model includes a positioning frame 1 located above the coal pile 5, and a spraying head 2 and a spraying guide mechanism 4 are provided at the lower part of the positioning frame 1.

[0016] The spray guiding mechanism 4 includes a positioning bushing 41 fixed to the positioning frame 1 at its upper part, a lifting rod 42 slidably disposed within the positioning bushing 41, a cylinder 45 connected to the upper part of the lifting rod 42, the cylinder 45 being mounted on the upper part of the positioning frame 1, a first connecting rod 43 evenly installed along the circumferential direction at the lower outer periphery of the positioning bushing 41, and a second connecting rod 44 installed on the lower outer periphery of the lifting rod 42 corresponding one-to-one with the first connecting rod 43. The two ends of the first connecting rod 43 are respectively hinged to the positioning bushing 41 and one end of the second connecting rod 44, and the other end of the second connecting rod 44 is hinged to the lifting rod 42. A flexible guide cloth 46 is installed between the first connecting rods 43 to form an integrated structure (see [reference]). Figure 2 The flexible guide cloth 46 is made of waterproof material. The spray head 2 is connected to the water inlet pipe 3 through the auxiliary water pipe 21. There are two or more sets of spray heads 2. The spray heads 2 are symmetrically arranged with the positioning bushing 41 as the center. The distance between the spray head 2 and the positioning bushing 41 is less than the length of the first connecting rod 43.

[0017] In this device, spray heads are arranged around the circumference of the spray guide mechanism. The spray guide mechanism controls the opening angle of the first connecting rod and the flexible guide cloth through the lifting rod. The spray heads first spray water onto the flexible guide cloth, and then slide down along the flexible guide cloth and diffuse into the air to form a dust prevention and dust suppression effect. It is easy to operate and has a large angle adjustment range.

[0018] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0019] During operation, water in the inlet pipe flows along the auxiliary water pipe to the spray head, which sprays the water onto the flexible guide cloth. The water then slides down the edge of the flexible guide cloth and spreads into the air. The opening angle of the flexible guide cloth is determined by the opening angle of the first connecting rod. The first connecting rod is hinged to the lifting rod through the second connecting rod. The angle of the first connecting rod can be controlled by controlling the height of the lifting rod with a cylinder. During the spraying process, the cylinder can also control the lifting rod to rise or fall along the positioning sleeve in real time. The flexible guide cloth changes regularly between opening and closing, effectively increasing the spraying area and improving the dust prevention and suppression effect.

[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
