Description

Technical Field

[0001] This utility model relates to the technical field of spray dust suppression equipment, and in particular to a top spray dust suppression device for underground coal mines. Background Technology

[0002] With the advancement of science and technology in today's society and the continuous improvement of mechanization in all walks of life, this is also true in coal mine production operations. Due to the confined space and poor ventilation in underground coal mining, a lot of dust will inevitably be generated during the production process in coal mines, which seriously pollutes the underground environment and poses a certain threat to the working environment; in particular, coal mining machines will generate a lot of dust during the coal mining process.

[0003] Currently, common methods for dust control in coal mines include increasing ventilation or installing spray dust suppression devices. However, increasing ventilation only exacerbates the dust problem. Spray dust suppression is a more convenient solution, but most current methods simply use water pipes and atomizers to spray water into the mine shaft. The spray nozzles cannot rotate, resulting in a limited dust suppression range and affecting dust removal efficiency. Furthermore, when the dust collector stops, the humid air combines with dust and adheres to the nozzles, causing blockages and increasing maintenance costs. Therefore, these problems need to be addressed. Utility Model Content

[0008] Preferably, the transmission mechanism includes a motor mounted on the bottom surface of the top plate, a turntable mounted on the output end of the motor, a connecting rod hinged to one side of the turntable, and the other end of the connecting rod being movably hinged to the front end face of the first spray plate.

[0009] Preferably, the spraying mechanism includes a water supply pipe installed in the cavity, the top end of the water supply pipe is connected to a connecting pipe, and a corrugated pipe is installed at the bottom end of the water supply pipe. An atomizing nozzle is installed at the bottom end of the corrugated pipe, and sliding rods are fixedly connected to both sides of the atomizing nozzle. The sliding rods are slidably installed in the cavity groove.

[0010] Preferably, the upper ends of the plurality of sliding rods pass through the first spray plate and the second spray plate, and a push plate is installed at the top of the sliding rod at the same end. A cylinder is installed on the top surface of the push plate, and a connecting plate is installed at the other end of the cylinder.

The lower end of the second spray plate 4 has multiple equidistant meshing grooves, and the meshing grooves at the lower ends of the first spray plate 3 and the second spray plate 4 are interlaced. A connecting pipe is installed at the upper end of the interior of the first spray plate 3 and the second spray plate 4. One side of the connecting pipe passes through the first spray plate 3 and the second spray plate 4, and a hose 7 is connected to the other side of the connecting pipe. Water is easily transmitted to the first spray plate 3 and the second spray plate 4 through the hose 7. A water pump 6 is installed at the other end of the hose 7. The water pump 6 is located at the lower end of the spray mechanism, and a water inlet pipe is connected to the other side of the water pump 6. The transmission mechanism includes a motor 8 installed on the bottom surface of the top plate 1. The motor 8 can easily drive the turntable 9 to rotate. The output end of the motor 8 is equipped with the turntable 9. The turntable 9 can easily cooperate with the connecting rod 10. The connecting rod 10 is hinged to one side of the turntable 9. The connecting rod 10 can easily drive the first spray plate 3 to rotate. The other end of the connecting rod 10 is movably hinged to the front end face of the first spray plate 3.

[0022] In this invention, the spraying mechanism includes a water supply pipe 11 installed in a cavity, which facilitates the delivery of water. The top end of the water supply pipe 11 is connected to a connecting pipe, and a corrugated pipe 13 is installed at the bottom end of the water supply pipe 11. The corrugated pipe 13 ensures normal water transport even when the atomizing nozzle 14 extends and retracts. The atomizing nozzle 14 is installed at the bottom end of the corrugated pipe 13, which facilitates the conversion of liquid into a spray. Sliding rods 12 are fixedly connected to both sides of the atomizing nozzle 14, which facilitates the up-and-down movement of the atomizing nozzle 14 in conjunction with a sliding groove. The sliding rods 12 are slidably installed in the sliding groove of the cavity, and the upper ends of multiple sliding rods 12 penetrate through the first spray plate. The first spray plate 3 and the second spray plate 4 are connected by a push plate at the top of the slide rod 12. A cylinder 16 is installed on the top surface of the push plate, which facilitates the up and down movement of the push plate. A connecting plate 15 is installed at the other end of the cylinder 16, which facilitates the installation of the cylinder 16. The two connecting plates 15 are fixedly connected to the far ends of the first spray plate 3 and the second spray plate 4. The protection mechanism includes multiple torsion springs 17 that are equidistantly installed on the bottom surface of the first spray plate 3 and the second spray plate 4.

The diameter of the dustproof plate 18 is larger than the diameter of the cavity.

[0023] Working principle: When using this invention, firstly, the motor 8 is turned on, which drives the turntable 9 to rotate. The turntable 9, through the cooperation of the connecting rod 10 hinged to the first spray plate 3, drives the first spray plate 3 to reciprocate in a fan-shaped rotation. At this time, the gear 5 on the first spray plate 3 meshes with the gear 5 on the second spray plate 4, driving the second spray plate 4 to reciprocate in a fan-shaped rotation in the opposite direction. Then, the water pump 6 is turned on, and the water pump 6 delivers liquid into the hose 7, which is then transmitted through the cavity of the first spray plate 3 and the second spray plate 4. The liquid is transported to the water supply pipe 11, and then through the water supply pipe 11 and the corrugated pipe 13 to the atomizing nozzle 14. The atomizing nozzle 14 converts the liquid into a spray and sprays it out to remove dust in the coal mine. After the dust removal is completed, the cylinder 16 drives the atomizing nozzle 14 to move upward into the cavity through the slide rod 12. At this time, due to the action of the torsion spring 17, the dustproof plate 18 rotates to cover the bottom of the cavity, preventing dust from entering the cavity and thus protecting the atomizing nozzle 14 from clogging. Finally, the motor 8 is turned off and the power is disconnected.
