Description

Technical Field

[0001] This utility model relates to the field of side-loading rock-loading machine technology, and more specifically, to a spray dust suppression device for a side-loading rock-loading machine. Background Technology

[0002] The side-loading rock loading machine is a tracked trackless loading device, mainly used for loading operations in coal, semi-coal-rock roadways, and small-section full-rock roadways. However, it generates a large amount of dust during the loading of coal and rock.

[0003] A search revealed that utility model patent CN219081642U discloses a spray dust suppression device for a side-loading rock-loading machine. The device includes a rotating bucket with connecting ears fixedly installed on it. The bucket is movably mounted on the side-loading rock-loading machine via these connecting ears. A fixing plate and a fixing seat are fixedly installed on the upper side of the rotating bucket, arranged symmetrically on the left and right sides. A connecting pipe is rotatably installed between the fixing plate and the fixing seat. Multiple sets of branch pipes, connecting to the interior of the connecting pipe, are equidistantly fixed to the outer wall of the connecting pipe. Spray heads are located at the free ends of the branch pipes. In this patent, a linkage gear drives the connecting pipe to rotate back and forth, causing it to swing continuously. This causes the multiple spray heads to swing synchronously with the connecting pipe, increasing the spray range of the multiple spray heads and facilitating large-area dust suppression of the area above the rotating bucket, thus improving the dust suppression range. However, the above-mentioned patents still have the following shortcomings: the micro motor, half gear, linkage gear, return spring, etc. are directly exposed to the outside, which is easy to accumulate dust and affect the quality of the drive; and during the process of the bucket shoveling the rock, the rock is easy to hit the branch pipe and spray head, which is easy to damage them. Therefore, we have proposed a spray dust suppression device for a side unloading rock loading machine. Utility Model Content

[0024] Example:

[0025] Please see Figure 1-5 A dust suppression spray device for a side-loading rock loading machine includes a rotating bucket 1. Two support seats 2 are fixedly connected to the top surface of the rotating bucket 1. A rotating pipe 3 is rotatably connected between the two support seats 2. Multiple branch pipes 5 are fixedly connected to the side of the rotating pipe 3. Atomizing nozzles 6 are fixedly sleeved at the ends of the multiple branch pipes 5. A protective cover 7 is fixedly connected to the outside of one support seat 2. A connecting rod 8 is fixedly connected to one end of the rotating pipe 3. The end of the connecting rod 8 extends into the inner cavity of the protective cover 7 and is fixedly sleeved with a spur gear 9. A servo motor 10 is fixedly installed in the inner cavity of the protective cover 7. A half gear 11 is fixedly sleeved on the output shaft of the servo motor 10. The half gear 11 and the spur gear 9 mesh with each other. A torsion spring 12 is fixedly connected to the end of the spur gear 9. The end of the torsion spring 12 is connected to the side of one of the support seats 2. A protective mechanism 4 is provided between the two support seats 2.

[0026] For details, please refer to Figures 1 to 3 The protective mechanism 4 includes multiple support rods 15 fixedly connected between two support seats 2, and multiple arched frames 16 fixedly connected to the multiple support rods 15. The rotating tube 3 is sleeved on the inner side of the multiple arched frames 16.

[0027] In this embodiment, multiple atomizing nozzles 6 are respectively located between multiple sets of two arched frames 16 to avoid the arched frames 16 blocking the atomized water sprayed by the atomizing nozzles 6.

[0028] For details, please refer to Figure 1 and Figure 4 The other end of the rotating tube 3 extends to the outside of the support base 2 and is fixedly installed with a rotary joint 17. The end of the rotary joint 17 is fixedly connected with a liquid guiding hose 18.

[0029] In this embodiment, the end of the liquid guiding hose 18 is connected to the water tank on the rock loading machine so as to supply water to the rotating pipe 3 so that the water in the rotating pipe 3 can be atomized and sprayed out from the branch pipe 5 and the atomizing nozzle 6.

[0030] For details, please refer to Figure 1 and Figure 2 A spring hinge 13 is fixedly installed on the side of the end of the protective cover 7, and a sealing plate 14 is fixedly installed on the spring hinge 13. The sealing plate 14 is located at the end of the protective cover 7.

[0031] In this embodiment, the elastic force of the spring hinge 13 is used to seal the end of the protective cover 7 with the sealing plate 14, while the sealing plate 14 can be opened to inspect the inner cavity of the protective cover 7.

[0032] For details, please refer to Figure 1 The front of the rotating bucket 1 is provided with a material shovel slope 20.

[0033] In this embodiment, the inclined surface 20 of the shovel is used to facilitate loading rocks onto the rotating bucket 1.

[0034] For details, please refer to Figure 2 The rear of the rotating bucket 1 is fixedly connected with multiple mounting brackets 19.

[0035] In this embodiment, the rotating bucket 1 and the rock loading machine are connected by installing the connecting seat 19.

[0036] Working principle: When the rock loading machine drives the rotating bucket 1 to scoop the rock material, water is introduced into the inner cavity of the rotating pipe 3 through the water tank and water pump on the rock loading machine via the liquid guiding hose 18. At the same time, the water in the rotating pipe 3 is atomized and sprayed out from the branch pipe 5 and the atomizing nozzle 6. Simultaneously, the servo motor 10 is started to drive the half gear 11 to rotate. When the half gear 11 and the spur gear 9 mesh, the spur gear 9 drives the connecting rod 8, the rotating pipe 3, the branch pipe 5 and the atomizing nozzle 6 to rotate, changing the direction of the atomized water sprayed from the atomizing nozzle 6. At the same time, the torsion spring 12 is torsional. When the half gear 11 and the spur gear 9 no longer mesh, the rotating pipe 3, the branch pipe 5, the atomizing nozzle 6 and the spur gear 9 are reset by the elastic force of the torsion spring 12, so that the water mist sprayed from the atomizing nozzle 6 can suppress dust.

[0037] In addition, when the loading machine drives the rotating bucket 1 to scoop material, the rotating pipe 3, the branch pipe 5 and the atomizing nozzle 6 are protected by the support rod 15 and the arch frame 16. Furthermore, the spur gear 9, the half gear 11 and the spur gear 9 are protected by the protective cover 7 and the sealing plate 14 to prevent them from being hit by rocks.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
