Description

Technical Field

[0001] The utility model belongs to the technical field of coal dust reduction, and in particular relates to an automatic spraying system for a coal loading and unloading vehicle. Background Art

[0002] During the loading and unloading process, especially during loading, a large amount of coal dust will be generated at the coal loading station, which will cause serious pollution to the surrounding environment and pose a great threat to the health of on-site workers. After the coal is loaded and unloaded, water needs to be sprayed on the surface of the coal to achieve the purpose of dust reduction. This requires the use of spraying equipment.

[0003] A Chinese patent discloses a spray device and a coal dust suppression system (authorization announcement number CN204801822U). This patented technology uses a swing drive to control the rotating baffle, which not only simplifies the control structure of the rotating baffle and reduces the occupied space, but also makes the rotating baffle more accurate in switching the exposure and shielding states of the nozzle, thereby avoiding secondary pollution caused by residual solution on the nozzle dripping onto non-coal seam surfaces such as the front of the vehicle. However, it cannot effectively increase the spray angle, resulting in poor dust suppression effect. Utility Model Content

An infrared sensor 9 for detecting the coal loading and unloading vehicle is installed between the sprinkler heads 6 at the lower end of the outer side of the sprinkler pipe 1. A conveying mechanism for moving the sprinkler head 6 back and forth is installed on the outer side of the support pipe 8, and a rotating mechanism for adjusting the angle of the sprinkler head 6 is installed on the connecting pipe 2;

[0022] In this application, as Figure 1 and Figure 2 shown, the conveying mechanism includes a second motor 71 fixed to the outside and a second bearing 76 containing a bearing inside. The output end of the second motor 71 is fixedly connected to a driving synchronous pulley 72. The inner side of the second bearing 76 is connected to a driven synchronous pulley 75 through a connecting shaft. A synchronous belt 73 is installed on the outer sides of the driving synchronous pulley 72 and the driven synchronous pulley 75. The upper end of the synchronous belt 73 is fixedly connected to a support seat 74. The support seat 74 is fixed on the support pipe 8. By driving the driving synchronous pulley 72 to rotate by the second motor 71, the synchronous belt 73 rotates around the driving synchronous pulley 72 and the driven synchronous pulley 75, thereby driving the support seat 74 to move along with the synchronous belt 73, and further enabling the support pipe 8, the sprinkler pipe 1, the sprinkler head 6, and the connecting pipe 2 to move back and forth together, realizing spraying water on the entire carriage of the loading and unloading vehicle.

[0023] In this application, as Figure 1 and Figure 2As shown in the figure, one end of the support pipe 8 is provided with a second threaded joint 83, and a plug 81 is engaged and connected to the other end of the support pipe 8.

The support pipe 8 can be fixedly connected to the spray water pipe 1 through the second threaded joint 83; a part of the support pipe 8 can be rotated along with the spray water pipe 1 through the second rotary joint 82; the plug 81 can be used to block and dredge one end of the support pipe 8. When there is debris blockage in the spray water pipe 1, after the plug 81 is opened, the debris in the spray water pipe 1 can flow out from one end of the support pipe 8 along with the water flow.

[0024] In this application, as Figure 1 and Figure 3 shown, the rotating mechanism includes a first motor 41 fixed on the support plate 52 and a first bearing seat 44 containing bearings inside. The output end of the first motor 41 is fixedly connected with a driving gear 42. The outside of the driving gear 42 is meshed and connected with a driven gear 43. Both the driven gear 43 and the first bearing seat 44 are sleeved on the outside of the connecting pipe 2. A first rotary joint 22 is installed on one side of the connecting pipe 2 close to the driven gear 43. The driving gear 42 is rotated by the first motor 41, the driving gear 42 drives the driven gear 43 to rotate, and the driven gear 43 drives the connecting pipe 2 to rotate around the first bearing seat 44 as the center of the circle. At the same time, the first rotary joint 22 and the second rotary joint 82 rotate themselves, so that the spray water pipe 1 rotates at a certain angle, and the angle of the spray head 6 can be adjusted to increase the spraying range of the spray head 6. One end of the connecting pipe 2 is provided with a water inlet 21, and a first threaded joint 23 is provided at the other end of the connecting pipe 2. The water inlet 21 can be connected to an external water source through a flexible water pipe. After the water passes through the water hose, the water inlet 21 and the connecting pipe 2 in sequence, it enters the spray water pipe 1 and then sprays out from the spray head 6 to spray water on the carriage of the loading and unloading vehicle.

[0025] In this application, as Figure 1 and Figure 3 shown, two groups of guide sleeves 53 are fixedly connected to the lower end of the support plate 52. A guide rod 5 is slidably connected to the inside of each guide sleeve 53. Fixing frames 51 for fixing to the outside are fixedly connected to the front and rear ends of the guide rod 5. When the support pipe 8, the spray water pipe 1 and the connecting pipe 2 move along with the synchronous belt 73, the guide sleeve 53 slides along the guide rod 5, thus ensuring the stable movement of the spray water pipe 1.

[0026] In this application, as Figure 1 and Figure 3As shown in the figure, an air inlet pipe 3 is provided at one end of the outer side of the connecting pipe 2 close to the water inlet 21. A check valve 31 is installed on the air inlet pipe 3, and an air inlet 32 is provided at one end of the air inlet pipe 3.

Then, connect the air inlet 32 to an external compressed air device through a flexible hose; the water inlet 21 can be connected to an external water source through a flexible water pipe.

[0029] When the coal loading and unloading vehicle drives into the lower end of the spray water pipe 1, the infrared sensor 9 automatically detects the vehicle. At the same time, water enters the connecting pipe 2 after passing through the water hose and the water inlet 21 in sequence, and compressed air enters the connecting pipe 2 after passing through the flexible hose, the air inlet 32 and the air inlet pipe 3 in sequence; the compressed air is mixed with water in the connecting pipe 2 and then enters the spray water pipe 1, and is sprayed out in the form of atomization from the nozzle 6. The water mist is sprayed on the coal to achieve the purpose of dust suppression.

[0030] Then, turn on the second motor 71. The second motor 71 drives the driving synchronous pulley 72 to rotate, so that the synchronous belt 73 rotates around the driving synchronous pulley 72 and the driven synchronous pulley 75, thereby driving the support seat 74 to move along with the synchronous belt 73, and further enabling the spray water pipe 1 to move back and forth along the guide rod 5, realizing spraying water on the entire carriage of the loading and unloading vehicle. At the same time, turn on the first motor 41. The first motor 41 drives the driving gear 42 to rotate, the driving gear 42 drives the driven gear 43 to rotate, the driven gear 43 drives the connecting pipe 2 to rotate around the first bearing seat 44 as the center, and at the same time the first rotary joint 22 and the second rotary joint 82 rotate themselves, and further the spray water pipe 1 can rotate at a certain angle, expanding the spraying range of the nozzle 6 and improving the dust suppression effect.
