[0022] Example 1: Please refer to Figures 1-4 A dust suppression device for a bucket wheel stacker-reclaimer includes a bucket wheel tail car assembly 1 and a yard belt conveyor 2 installed at one end of the bucket wheel tail car assembly 1. A discharge hopper assembly 3 is installed at one end of the yard belt conveyor 2, and a running assembly 4 is installed at the lower end of the discharge hopper assembly 3.

A water supply tank 7 is installed on the lower end of the yard belt conveyor 2.

[0023] The bucket wheel stacker-reclaimer is equipped with a dust suppression component 6 and a water tank 7 connected by a hose. One end of the hose is connected to a water supply point located at the midpoint of the travel length. The water supply points on the machine are a centralized water supply tank 7 and a water tank 61 for the dust suppression devices. Water is introduced into the water supply tank 7 on the machine through ground water pipes, and the water supply tank 7 then supplies water to each dust suppression device.

A support mechanism 63 is disposed on the upper end of the rotating mechanism 62. A water supply mechanism 64 is disposed on one side of the upper end of the support mechanism 63. A water spraying mechanism 66 is connected to the middle of the upper end of the support mechanism 63 through a mounting mechanism 65.

[0025] The rotating mechanism 62 includes a first gear 621 fixedly installed on the upper end of the water tank 61. A movable shaft 622 is installed on the upper end of the first gear 621. The movable shaft 622 and the support mechanism 63 are fixedly installed, so that the support mechanism 63 and the first gear 621 are movably installed.

[0026] The outer surface of the first gear 621 is meshed with the second gear 623. An output shaft 624 is mounted on the upper end of the second gear 623. One end of the output shaft 624 is connected to a drive motor 625. The drive motor 625 is configured to drive the output shaft 624 and the second gear 623 to rotate. The drive motor 625 is fixedly mounted on the upper end of the support mechanism 63. By driving the output shaft 624 and the second gear 623 to rotate, the second gear 623 meshes with the first gear 621, causing the support mechanism 63 to rotate.

[0027] The dust suppression device can be used at the following points: the head of the cantilever conveyor belt (spraying during material stacking and reclaiming), the tail of the tail conveyor belt (spraying during material stacking), the head bucket wheel chute (spraying during material reclaiming), and the middle hopper (spraying during material reclaiming).

[0028] In this embodiment: The dust suppression device contains a high-pressure water pump 641, which draws water from the water tank and pressurizes it to a very high pressure, atomizing the water. Then, the water is atomized into fine mist particles of 0~30μm through the fine mist nozzle 663 and sprayed out. According to the principle of wind delivery, under the action of the fan 661, the high-pressure fan propels the water mist to the designated location, spraying and covering the dust area and above or around it. The design of the fine mist nozzle 663 allows the water to form a tiny water mist. The water mist fully integrates with the dust particles, gradually condensing into particle clusters. Under its own gravity, the particles quickly settle to the ground, thereby achieving the purpose of dust suppression.

[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 The support mechanism 63 includes a support platform 631 and fixed rods 632 fixedly installed on both sides of the upper end of the support platform 631.

One end of the water pumping pipe 642 is connected to a fine mist nozzle 663, and water is supplied to the fine mist nozzle 663 through the high-pressure water pump 641.

[0031] The erection mechanism 65 includes a hydraulic rod 651 and an extension rod 652 located at the middle of the upper end of the hydraulic rod 651. The lower end of the hydraulic rod 651 is movably connected to a connecting shaft and a concave block 633.

[0032] The water spraying mechanism 66 includes a fan 661 and a blower 662 located at one end of the fan 661. A fine mist nozzle 663 is provided at one end of the blower 662. The two ends of one side of the outer wall of the fan 661 are movably installed via a connecting rod 664 and a fixing rod 632, respectively. A corresponding connecting shaft 665 is provided at one end of the outer wall of the fan 661. The corresponding connecting shaft 665 and the extension rod 652 are movably installed. The fan 661 is driven to adjust the set angle by activating the hydraulic rod 651.

[0033] In this embodiment: by activating the hydraulic rod 651, the extension rod 652 is moved. The extension rod 652 is connected to the fan 661 through the corresponding connecting shaft 665, so that one end of the fan 661 is lifted by the extension of the hydraulic rod 651. At the same time, the connecting rods 664 on both sides of the other end of the outer wall of the fan 661 are movably connected to the fixing rod 632, so that the fixing rod 632 supports the other end of the outer wall of the fan 661, and the other end of the fan 661 changes its angle together with the end of the fan 661 lifted by the hydraulic rod 651, thereby realizing the change of the spraying angle of the dust suppression device.

[0034] Working principle: The dust suppression device contains a high-pressure water pump 641, which draws water from the water tank, pressurizes it to a high pressure, atomizes the water, and then sprays it out as fine mist particles of 0-30μm through fine mist nozzles 663. Based on the principle of wind delivery, the high-pressure fan 661 propels the water mist to the designated location, spraying and covering the dusty area, above it, or around it. The design of the fine mist nozzles 663 allows the water to form tiny water mists, which fully mix with the dust particles, gradually condense into particle clusters, and quickly settle to the ground under their own gravity, thereby achieving dust suppression. The purpose is to move the extension rod 652 by activating the hydraulic rod 651. The extension rod 652 is connected to the fan 661 through the corresponding connecting shaft 665, so that one end of the fan 661 is lifted by the extension of the hydraulic rod 651. At the same time, the connecting rods 664 on both sides of the other end of the outer wall of the fan 661 are movably connected to the fixed rod 632, so that the fixed rod 632 supports the other end of the outer wall of the fan 661, and the other end of the fan 661 changes its angle together with the end of the fan 661 lifted by the hydraulic rod 651, thereby changing the spray angle of the dust suppression device.
