Technical Field

[0001] The utility model relates to an excavator spray device, belonging to the technical field of excavators. Background Art

[0002] Currently, there are many types of excavators. Common excavators are divided into two types based on their drive mode: internal combustion engine-driven excavators and electric-driven excavators. Electric excavators are primarily used in oxygen-deficient plateaus, underground mines, and other flammable and explosive locations. Based on their travel mode, excavators can be divided into crawler excavators and wheeled excavators. Based on their transmission mode, excavators can be divided into hydraulic excavators and mechanical excavators. Existing excavators generate a large amount of dust during operation, which affects the working environment and the workers' vision. Dust removal is usually carried out using mist cannons or nozzles.

[0003] When existing excavators use fog cannons or nozzles for dust removal, some dust and water vapor tend to adhere to the glass around the excavator cab, blocking the workers' vision, which is not conducive to the normal progress of construction work and affects the safety of the excavator.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] like Figure 1-Figure 2 and Figure 5As shown, the utility model provides an excavator spray device, including an excavator shell 1, a mounting block 2 is provided on the top of the excavator shell 1, and a spray mechanism and a water storage mechanism are respectively provided on both sides of the mounting block 2 on the top of the excavator shell 1, a first flow channel 3 is opened in the mounting block 2, one end of the first flow channel 3 is connected to the water storage mechanism through an input pipe 4, and the other end of the first flow channel 3 is connected to the spray mechanism through an output pipe 5; a second flow channel 6 connected to the first flow channel 3 is also opened in the mounting block 2, and valves 14 are matched in the first flow channel 3 and the second flow channel 6. A rotating shaft 7 is provided on one side of the inner wall of the second flow channel 6, and a fan blade 8 is provided at one end of the rotating shaft 7 in the second flow channel 6. The other end of the rotating shaft 7 extends to the outside of the mounting block 2 and is provided with a transmission mechanism. The outer wall of the excavator shell 1 is symmetrically provided with brackets 10 on both sides of the rotating shaft 7, and a cleaning mechanism with a sliding connection is provided in the bracket 10. The transmission mechanism is used to drive the cleaning mechanism to reciprocate left and right along the bracket 10.

[0028] Specifically, water is added to the water storage mechanism. When the excavator is excavating, the device performs a spraying operation. First, the water storage mechanism starts to work, opens the valve 14 in the first flow channel 3, and closes the valve 14 in the second flow channel 6. At this time, the second flow channel 6 is closed and the first flow channel 3 is opened. Then the water storage mechanism transports the water to one side of the mounting block 2 through the input pipe 4. After the water passes through the first flow channel 3, it moves to the spray mechanism through the output pipe 5. Then the spray mechanism sprays in the direction of the excavator bucket, thereby performing dust removal to prevent dust from affecting the surrounding environment. When dust and water vapor adhere to the outer wall of the excavator shell 1 and affect the staff's field of vision, the valve 14 in the first flow channel 3 can be controlled to be closed, and the valve 14 in the second flow channel 6 can be opened, so that when the water passes through the mounting block 2, it passes through the second flow channel 6 and then the first flow channel. 3 and is discharged from the output pipe 5. At this time, the water flow can drive the fan blades 8 to rotate, thereby driving the rotating shaft 7 to rotate. The rotating shaft 7 drives the cleaning mechanism to reciprocate left and right along the bracket 10 through the transmission mechanism, thereby cleaning the outer wall of the excavator shell 1 close to the bucket direction, avoiding dust and water vapor from blocking the staff's field of vision, and ensuring the safety of the device; optionally, the diameter of the second flow channel 6 is smaller than the diameter of the first flow channel 3. When the water flows through the second flow channel 6, the flow rate will be accelerated, thereby driving the fan blades 8 and the rotating shaft 7 to rotate, ensuring that the transmission mechanism can be driven to move, and at the same time, the power of the water pump 13 can be increased to ensure the stability of the device during operation; optionally, the first gear 9 and the second gear 25 are both bevel gears. When the spraying work is performed normally, the valve 14 in the second flow channel 6 is closed to prevent the fan blades 8 from rotating and reduce losses.

[0029] The utility model cooperates with the valve 14, the second flow channel 6, the fan blade 8 and the rotating shaft 7. When the device is working normally, the water flow can enter the interior of the spray mechanism through the first flow channel 3, so that the spray dust removal work can be carried out normally. When dust and water vapor adhere to the excavator shell 1 and block the staff's line of sight, the corresponding valve 14 can be controlled to open and close, so that the water flow enters the interior of the spray mechanism after passing through the second flow channel 6, and the fan blade 8 and the rotating shaft 7 are driven to rotate by the water flow, so that the transmission mechanism drives the cleaning mechanism to reciprocate left and right along the bracket 10, and cleans the outer wall of the excavator shell 1 near the bucket direction, so as to avoid dust and water vapor blocking the staff's field of vision, ensure that construction work can be carried out normally, and ensure the safety of the device.

[0030] like Figure 3 As shown, in one embodiment, the transmission mechanism includes a first gear 9 provided at one end of the rotating shaft 7, a reciprocating screw 11 is provided on the inner wall of the bracket 10 for rotation connection, a second gear 25 meshing with the first gear 9 is provided at one end of the reciprocating screw 11, and the cleaning mechanism is threadedly connected to the reciprocating screw 11.

[0031] Specifically, when water flows through the second flow channel 6, it drives the fan blades 8 and the rotating shaft 7 to rotate, and the rotating shaft 7 drives the first gear 9 to rotate, thereby driving the two second gears 25 to rotate synchronously, and the second gear 25 drives the reciprocating screw 11 to rotate, thereby driving the cleaning mechanism to reciprocate left and right along the bracket 10, thereby cleaning the outer wall of the excavator shell 1; specifically, the two second gears 25 are engaged with the first gear 9. When the first gear 9 rotates, it can drive the two second gears 25 to rotate at the same time, thereby driving the two cleaning mechanisms to approach or move away from each other, so as to clean the outer wall of the excavator shell 1, avoid cleaning dead corners, and ensure the cleaning effect of the cleaning mechanism.

[0032] In one embodiment, the water storage mechanism includes a water tank 12 arranged on the top of the excavator shell 1, and a water pump 13 connected to the water tank 12 is provided on the outer wall of the water tank 12, and the water pump 13 is connected to the first flow channel 3 through the input pipe 4; a through groove is opened on one side of the outer wall of the water tank 12, and a transparent plate 15 is matched in the through groove.

[0033] Specifically, before the work starts, water can be input into the water tank 12. When the work starts, the water pump 13 starts working to transport the water in the water tank 12 to the input pipe 4. Optionally, the water level in the water tank 12 can be observed through the transparent plate 15 in the through groove to obtain the water volume in the water tank 12. Water can be added according to the result, thereby ensuring the convenience of the device.

[0034] like Figure 4As shown, an embodiment, the spray mechanism includes a first telescopic rod 16 rotatably arranged on one side of the outer wall of the mounting block 2, and a second telescopic rod 17 is rotatably arranged on the top of the excavator shell 1 on one side of the mounting block 2, one end of the second telescopic rod 17 is rotatably connected to the outer wall of the first telescopic rod 16, and a frame 18 is provided at one end of the first telescopic rod 16, and a plurality of atomizing nozzles 19 are rotatably arranged on the inner side of the frame 18, and a rotatably connected central shaft 20 is provided on the inner side of the frame 18, and the plurality of atomizing nozzles 19 are all connected to the central shaft 20, and the central shaft 20 is connected to the output pipe 5, and the outer wall of the frame 18 is provided with a motor 21 for driving the central shaft 20 to rotate.

[0035] Specifically, during operation, after the water pump 13 transports water to the inside of the output pipe 5, the water then enters the inside of the atomizing nozzle 19, and is then sprayed out through the atomizing nozzle 19, which removes dust from the environment around the excavator bucket, avoids affecting the surrounding environment, and ensures the working effect of the device; according to actual work needs, the motor 21 can be controlled to start working, thereby driving the central axis 20 to deflect a certain angle, so as to drive multiple atomizing nozzles 19 to rotate, and adjust the working angle and direction of the atomizing nozzle 19, thereby expanding the working range of the atomizing nozzle 19 and ensuring the practicality of the application; optionally, the frame 18 plays a supporting role with respect to the central axis 20; based on According to actual work needs, the first telescopic rod 16 can be controlled to extend and retract, thereby driving the frame 18 and the atomizing nozzle 19 to move, and the second telescopic rod 17 can be controlled to extend and retract, and the angle of the first telescopic rod 16 can be controlled. Through the cooperation of the first telescopic rod 16 and the second telescopic rod 17, the position of the atomizing nozzle 19 is adjusted, further expanding the use range of the atomizing nozzle 19. When the position of the atomizing nozzle 19 changes, the output pipe 5 moves accordingly. Optionally, the output pipe 5 is a hose to avoid it affecting the adjustment work of the atomizing nozzle 19; optionally, the number of the first telescopic rod 16 and the second telescopic rod 17 are both two, and they are distributed on both sides of the rotating shaft 7.

[0036] like Figure 1-2 As shown, in one embodiment, the cleaning mechanism includes a support block 22, the support block 22 is slidably connected to the bracket 10, the support block 22 is threadedly connected to the reciprocating screw 11, and a slidingly connected cleaning brush 23 is provided on the outer wall of the support block 22 close to the excavator shell 1, and the outer wall of the cleaning brush 23 is elastically connected to the support block 22 through a plurality of springs 24 away from the excavator shell 1.

[0037] During use, when the reciprocating screw 11 rotates, it can drive the support block 22 to reciprocate left and right along the bracket 10, and the cleaning brush 23 moves with the support block 22, thereby cleaning the outer wall of the excavator shell 1. The spring 24 is used to push the cleaning brush 23 toward the excavator shell 1, thereby ensuring that the cleaning brush 23 contacts the outer wall of the excavator shell 1, so as to facilitate the cleaning of the excavator shell 1 and ensure the working effect of the device.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
