Description

Technical Field

[0001] This utility model relates to the field of chain bucket unloader technology, and in particular to a dustproof cover for the head of the material handling arm of a chain bucket unloader. Background Technology

[0002] With the development of continuous unloading technology for bulk materials, chain bucket unloaders have emerged. This technology uses the exposed chain buckets of the material handling arm to continuously dig out materials (such as cement). It features high material handling efficiency, strong adaptability, and continuous operation, and has thus become an important piece of equipment for unloading powdery and granular materials in ports, power plants, and other places.

[0003] In related technologies, the dust problem generated during ship unloading operations is usually addressed by methods such as local enclosed ventilation for dust removal, spraying for dust suppression, or solidification of material surfaces, or by incorporating dust-proof design into the overall structure of the equipment.

[0004] However, the aforementioned general dust suppression methods or related devices have the following problems when dealing with dust generated at the head of the chain bucket unloader's take-up arm:

[0005] Because the head of the reclaiming arm is designed to be open, the fan effect generated by the operation of the chain bucket will blow air toward the surface of the material in the hold, causing dust. At the same time, the material slids back into the hold from the high-speed moving chain bucket after being excavated, which will also generate secondary dust. At present, it is difficult to effectively cover and suppress the dust generated at this open and dynamic work point, which will lead to serious dust spread, not only polluting the environment, but also seriously affecting the visibility and safety of the reclaiming operation. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides a dust cover for the head of the material handling arm of a chain bucket unloader, which can effectively suppress the dust diffusion problem generated when the material handling arm head digs cement and improve visibility during the material handling operation.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A dust cover for the head of the material handling arm of a chain bucket unloader includes:

[0009] A dustproof component is installed at the head of the material handling arm, which covers the entire head of the material handling arm and defines the length and height directions based on the structure of the dustproof component;

[0010] The dustproof assembly consists of a front cover assembly, a side cover assembly, and a rear cover assembly, which are sequentially spliced ​​together along the length direction.

[0011] A skirt assembly connected in the height direction to the bottom of the front cover assembly, side cover assembly and rear cover assembly;

[0012] The length of the skirt assembly in the longitudinal direction is greater than the sum of the lengths of the front cover assembly, the side cover assembly, and the rear cover assembly in the longitudinal direction;

[0013] The bottom of the front cover assembly has a forward protrusion along the length direction, and the side of the skirt assembly near the forward protrusion of the front cover assembly is matched and connected to the forward protrusion to form a space expansion buffer. The space expansion buffer reduces the dust generated by the "fan effect" of the chain bucket rotation.

[0014] The front cover assembly, side cover assembly, rear cover assembly, and skirt assembly together enclose the head of the material handling arm, forming a closed dustproof space.

[0015] As a further improvement to the above technical solution:

[0016] In one embodiment, the front cover assembly includes a front cover frame and a plurality of front cover panels covering the front cover frame; the side cover assembly includes a side cover frame and a plurality of side cover panels covering the side cover frame; and the rear cover assembly includes a rear cover frame and a plurality of rear cover panels covering the rear cover frame.

[0017] In one embodiment, the front cover frame, side cover frame and rear cover frame are all fixed to the material handling arm by bolts.

[0018] In one embodiment, the front cover, side cover, rear cover, and skirt cover are all detachable steel plates.

[0019] In one embodiment, the skirt assembly includes a skirt frame and multiple skirt covers covering the skirt frame; the length of the skirt frame in the longitudinal direction is greater than the sum of the lengths of the front cover frame, the side cover frame and the rear cover frame in the longitudinal direction.

[0020] In one embodiment, a rubber curtain is fixed to the bottom of the skirt frame, and the rubber curtain extends to the surface of the cabin material to form a flexible sealing structure.

[0021] In one embodiment, the rubber curtain is composed of two layers of rubber sheets.

[0022] In one embodiment, the rubber curtain is fixed to the bottom of the skirt frame by bolts.

[0023] In one embodiment, the skirt frame is welded and fixed to the material handling arm.

[0024] In one embodiment, the enclosed structure of the dustproof component confines the dust generated by the chain bucket rotating excavation operation inside the protective cover, and the skirt component and the rubber curtain work together to suppress the diffusion of dust to the outside.

[0025] The beneficial effects of this utility model are as follows:

[0026] This utility model has a compact structure. The upper frame is formed by splicing the front cover assembly, side cover assembly and rear cover assembly. Combined with the lower skirt assembly and rubber curtain flexible sealing, the chain bucket digging operation is completely wrapped in the entire dustproof assembly, eliminating the conditions for dust generation from the source. At the same time, the cement thrown back by the chain bucket is blocked by the inner wall of the cover and cannot spread to the outside space, thus solving the dust problem.

[0027] This utility model also has the following advantages:

[0028] (1) The length of the skirt of this utility model is greater than the sum of the lengths of the front cover, side cover and back cover. By covering the material digging trajectory of the chain bucket with the skirt, it is ensured that the material is in the shielded area of ​​the cover throughout the entire sliding process.

[0029] (2) The bottom of the skirt of this utility model is bolted to a double-layer rubber curtain, which is in close contact with the surface of the material in the cabin to form a flexible seal without dead angles, making it more suitable for complex working conditions.

[0030] (3) The front cover assembly, side cover assembly and rear cover assembly of this utility model all adopt a split structure of frame and multiple cover plates, and the cover plates are detachable steel plates; when a single cover plate is damaged, it can be replaced separately without removing the whole cover, reducing downtime; at the same time, only the partial cover plate needs to be removed to expose the internal chain bucket, avoiding the defect of traditional closed structure that requires the whole structure to be removed during later equipment maintenance.

[0040] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0041] like Figures 1-3 The accompanying drawing shows a schematic diagram of the structure of a dustproof cover for the head of the material handling arm of a chain bucket unloader according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0042] In this embodiment, the application scenario is the unloading of 1000 tons of cement at the head of the material handling arm of a chain bucket unloader.

[0043] In this embodiment, a dust cover for the head of the material handling arm of a chain bucket unloader is provided, including a dustproof component disposed at the head of the material handling arm, which covers the entire head of the material handling arm, and the length and height directions are defined based on the structure of the dustproof component;

[0044] The front cover assembly, side cover assembly and rear cover assembly are spliced ​​together along the length direction to form an upper frame that covers the chain bucket operation area.

[0045] In the vertical direction, the skirt assembly 700 extends downwards, and the bottom of the skirt assembly 700 is connected to the rubber curtain 900, which is attached to the surface of the cabin material.

[0046] In this embodiment, the front cover frame 100 of the front cover assembly is fixed to the front end of the material handling arm by bolts, and the frame surface is covered with multiple detachable front cover plates 200.

[0047] In this embodiment, the side cover frame 300 of the side cover assembly is fixed to both sides of the material handling arm by bolts, and the outside is covered by multiple detachable side cover plates 400.

[0048] In this embodiment, the rear cover frame 500 of the rear cover assembly is fixed to the tail of the material handling arm by bolts, and the surface is covered with multiple detachable rear cover plates 600.

[0049] Furthermore, the front cover 200, side cover 400, and rear cover 600 are all made of steel plates, and each piece can be replaced independently if it is damaged.

[0050] In this embodiment, the skirt frame 700 is welded and fixed to the bottom of the material picking arm. At the same time, the length of the skirt frame 700 is greater than the total splicing length of the front cover frame 100, the side cover frame 300 and the rear cover frame 500.

[0051] Furthermore, the surface of the skirt frame 700 is covered with multiple removable skirt cover plates 800, forming a sloping surface extending into the cabin.

[0052] In this embodiment, the bottom of the skirt frame 700 is fixed with bolts to a double-layer rubber curtain 900; during operation, the rubber curtain 900 extends down with the material handling arm, and the double-layer structure forms a flexible seal against the surface of the cement 1000 material, suppressing dust from escaping from the bottom.

[0053] In practical applications, the principle of this invention is as follows:

[0054] When the chain bucket digs 1000 cement, the bottom of the front cover assembly has a forward protrusion along the length direction, and the side of the skirt assembly near the forward protrusion of the front cover assembly is matched and connected with the forward protrusion to form a space expansion buffer. The space expansion buffer reduces the dust generated by the "fan effect" of the chain bucket rotation, and the bottom gap is sealed by the rubber curtain 900 to achieve sealing.

[0055] Furthermore, removing any one of the cover plates exposes the chain bucket components, eliminating the need to remove the entire protective cover for later maintenance.

[0056] In summary, the present invention has a reasonable structure. The upper frame is formed by splicing the front cover assembly, the side cover assembly, and the rear cover assembly. Combined with the lower skirt assembly and the flexible sealing of the rubber curtain, the chain bucket digging operation is completely wrapped in the entire dustproof assembly, eliminating the conditions for dust generation from the source.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
