Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to an environmental protection structure of a hopper. Background Art

[0002] A bridge-type grab unloader is a bridge-type crane that uses a moving trolley to drive a grab to grab materials from a ship's hold and unload the materials into a funnel on the machine. It belongs to a bulk material intermittent (or periodic) ship unloading machine. The bridge-type grab unloader has the characteristics of high efficiency, stability, safety, and simple operation, so it is widely used in the ship unloading operation of bulk goods at docks.

[0003] However, when the grab of the existing bridge-type grab unloader unloads materials into the hopper, dust is easily generated. Since the top of the hopper is a completely open structure, the dust is easily diffused outwards through the top of the hopper, which will cause certain pollution to the surrounding environment.

[0008] As a still further scheme of the utility model: A water delivery hose is connected to the tee pipe, and the other end of the water delivery hose is connected to a ground water pump.

[0009] As a further solution of the present utility model: A space is left between the two upper flip covers to facilitate the movement of the ship unloader's lifting rope.

[0010] As a further solution of the present utility model: The first electric telescopic rod and the second electric telescopic rod are electrically connected to a switch installed in the cab of the ship unloader.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the mutual cooperation of the side windshields, rear windshields, upper flip covers, second electric telescopic rods, and first electric telescopic rods, the present utility model can, to a certain extent, block the rising dust during the unloading of the grab bucket into the hopper through the mutual cooperation of the windshields and the upper flip covers, reduce the leakage of dust, thereby reducing the spread of dust and lowering the pollution to the surrounding air, achieving an environmental protection effect.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1-2, in the embodiment of the present utility model, an environmental protection structure of a hopper includes a hopper body 1. On both sides of the upper part of the hopper body 1, side windshields 3 are symmetrically arranged. The side windshields 3 are fixedly connected to the hopper body 1. An upper flip cover 4 is arranged on the side windshields 3. A first hinge 5 is arranged between the upper flip cover 4 and the side windshields 3, and the upper flip cover 4 is hinged to the side windshields 3 through the first hinge 5. A first electric telescopic rod 6 is arranged inside the side windshields 3. The cylinder end of the first electric telescopic rod 6 is hinged to a first extension plate 10 installed on the inner side surface of the side windshields 3, and the piston end of the first electric telescopic rod 6 is hinged to the inner side surface of the upper flip cover 4. A rear windshield 7 is arranged at the rear of the upper part of the hopper body 1. A second hinge 8 is arranged between the rear windshield 7 and the hopper body 1, and the rear windshield 7 is hinged to the hopper body 1 through the second hinge 8. A second electric telescopic rod 9 is arranged at the rear of the rear windshield 7. The cylinder end of the second electric telescopic rod 9 is hinged to a second extension plate 11 installed on the hopper body 1, and the piston end of the second electric telescopic rod 9 is hinged to the outer side surface of the rear windshield 7. A space for the lifting rope of the ship unloader to move is left between the two upper flip covers 4;

[0020] The first electric telescopic rod 6 and the second electric telescopic rod 9 are electrically connected to a switch installed in the cab of the ship unloader, so that the driver of the ship unloader can conveniently control the first electric telescopic rod 6 and the second electric telescopic rod 9 in the cab.

[0021] The present utility model can, when the grab discharges materials into the hopper, cooperate with the windshields and the upper flip cover 4 to block the raised dust to a certain extent, reduce the leakage of dust, thereby reducing the spread of dust and reducing the pollution to the surrounding air, achieving an environmental protection effect.

[0022] Please refer to Figure 1 and Figure 3 , spray racks 2 are installed on the inner side surfaces of the two upper flip covers 4. The spray racks 2 include a main pipe 201, branch pipes 202 and a tee pipe 203. A number of branch pipes 202 are equidistantly installed on both sides of the main pipe 201. Atomizing nozzles are provided on the branch pipes 202. A tee pipe 203 is arranged in the middle of the main pipe 201. The tee pipe 203 is embedded and installed on the upper flip cover 4. A water delivery hose 12 is connected to the tee pipe 203. The other end of the water delivery hose 12 is connected to a ground water pump. Through the ground water pump, water in a ground water tank or water tank can be conveyed into the spray racks 2 through the water delivery hose 12 for continuous dust suppression by spraying.

[0023] The present utility model, by installing the spray racks 2 on the inner side surface of the upper flip cover 4, connecting the spray racks 2 to the ground water tank through a ground water pump, and the water mist sprayed by the spray racks 2 can perform dust suppression treatment on the dust above the hopper body 1, further reducing the spread of dust.

[0024] Please refer to Figure 1, the hopper body 1 is arranged below the bridge-type grab ship unloader, and the grab of the bridge-type grab ship unloader is located between the windshields of the hopper body 1.

[0025] The working principle of the present utility model is as follows:

[0026] During use, when unloading the ship, the first electric telescopic rod 6 contracts to drive the left and right upper covers 4 to fall and cover the hopper 1. At the same time, the second electric telescopic rod 9 extends to drive the rear windshield 7 to rise. At this time, the left and right side windshields 3, the rear windshield 7, and the left and right upper covers 4 form a relatively airtight space, wrapping the grab inside. The grab safely enters above the hopper body 1 from the front and opens the grab in this airtight space. At this time, most of the dust will be wrapped in this relatively airtight space and cannot spread outwards. At the same time, the spray rack 2 installed on the upper cover 4 will spray downwards to reduce dust, further reducing the outward spread of dust.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
