Abstract
Description
Technical Field
[0001] This utility model relates to the field of excavator technology, specifically to a mechanical spray guard for excavators with adjustable spray angle. Background Technology
[0002] Excavators use their buckets to excavate materials above or below the machine's bearing surface. During the excavation process, excavators generate dust, necessitating the use of an excavator spraying system. This system is an environmentally friendly auxiliary device specifically designed for excavators, aiming to reduce dust pollution during construction and provide some cooling, thereby ensuring the environmental quality of the construction site and the health and safety of the workers.
[0003] Reference to Chinese utility model patent CN222413218U discloses a dust suppression spraying device for excavators, relating to the field of excavator-related technology. The device includes: a pipe clamp fixed to the surface of the excavator's robotic arm; a water supply pipe located inside the pipe clamp; a water storage device installed on the excavator, with the first end of the water supply pipe connected to the water storage device; and a pair of water distributors located above the excavator's bucket and symmetrically installed on both sides of the excavator's robotic arm. This application secures the robotic arm by clamping it with two connecting plates, passing two screws through both ends of the connecting plates, and then screwing four nuts onto the outside of the two screws. This facilitates fixing the water distributors to the robotic arm. The water storage device then supplies water to the water distributors via the water supply pipe, which is then sprayed out from the spray nozzles. With four spray nozzles positioned at different locations on the outer end of the water distributors, dust suppression can be easily carried out according to different directions, angles, and work sites, making it widely applicable.
[0004] Based on existing solutions and actual production and processing, the current mechanical spray guards for excavators still have some problems, such as the difficulty in adjusting the spray angle when spraying at the excavation site. Therefore, we propose a mechanical spray guard for excavators with an adjustable spray angle to solve the problems mentioned above. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1: Please refer to Figures 1-6 The existing mechanical spray guards for excavators are not convenient for adjusting the spray angle when spraying the excavation site. In order to solve this technical problem, this embodiment discloses the following technical content;
[0029] A mechanical spray guard for excavators with adjustable spray angle has a water tank 6 on the upper surface of the base 1, and a water inlet pipe 7 is fixedly connected to the top center of the water tank 6. A cap 8 is threadedly connected to the top outer side of the water inlet pipe 7. A housing 9 is fixedly connected to the left end of the upper surface of the fixing mechanism. A vent 10 and a through hole 11 are respectively opened at the front and rear ends of the housing 9. A high-pressure water pump 12 is fixedly connected to the left end of the interior of the housing 9. A first high-pressure hose 13 and a second high-pressure hose 14 are fixedly connected to the inlet and outlet of the high-pressure water pump 12, respectively.
[0030] The top end of the second high-pressure hose 14 is connected through the inside of the through hole 11, and the T-shaped groove 15 opened on the outer side of the bottom ends of the second high-pressure hose 14 is slidably connected to the T-shaped ring block 18 fixedly connected to the inner end of the nozzle 17. The inner side of the inner end of the nozzle 17 is in contact with the outer side of the bottom end of the second high-pressure hose 14. The top inner end of the nozzle 17 is threaded with a second stabilizing bolt 19, and a number of nozzles 20 are fixedly connected at equal intervals at the bottom of the nozzle 17.
[0031] Rotate the cap 8 off the water inlet pipe 7 to store water into the water storage tank 6 through the water inlet pipe 7. After the water storage tank 6 is full, rotate the cap 8 back onto the water inlet pipe 7.
[0032] Before spraying, adjust the spraying angle of the nozzle 20 according to the excavation situation and environment on site. First, loosen the second stabilizing bolt 19, rotate the nozzle 17, and adjust the spraying angle of the nozzle 20. After the adjustment is completed, tighten the second stabilizing bolt 19 and fix the nozzle 17 to the bottom of the second high-pressure hose 14. After the angle of the nozzle 20 is adjusted, spraying can be carried out during excavation.
[0033] During spraying, the high-pressure water pump 12 is started, and the high-pressure water pump 12 draws water out of the water storage tank 6. The water passes through the first high-pressure hose 13, the high-pressure water pump 12 and the second high-pressure hose 14, and is finally sprayed out by the nozzle 20. The high-pressure water pump 12 can generate high-pressure water flow, which improves spraying efficiency and effect.
[0034] Example 2: Existing mechanical spray guards for excavators are prone to damage from prolonged exposure to air and sunlight, making maintenance inconvenient. Furthermore, preventing water leakage from the connection points is difficult when spraying water. Therefore, this example uses the following technical solution: Figures 1-6 As shown;
[0035] The fixing mechanism is composed of mounting plate 2, mounting hole 3, square ring plate 4 and first stabilizing bolt 5. Mounting plate 2 is fixedly connected to the front and rear ends of the lower surface of base 1, and mounting hole 3 is opened at both ends of the mounting plate 2. Square ring plate 4 is fixedly connected to the upper left and right ends of base 1 by first stabilizing bolt 5, and the inner side of square ring plate 4 is in contact with the outer side of water storage tank 6.
[0036] When fixing the water tank 6 to the excavator, first use bolts to fix the base 1 and mounting plate 2 to the excavator. Then, place the water tank 6 on the upper surface of the base 1, and then place the square ring plate 4 on the upper left and right sides of the outside of the water tank 6. Finally, use the first stabilizing bolt 5 to fix the front and rear bottom ends of the square ring plate 4 to the base 1. This completes the installation of the water tank 6. This installation can fix the water tank 6 firmly to the excavator, and the fixing mechanism can also be disassembled to maintain the water tank 6.
[0037] The bottom left and right outer ends of the second high-pressure hose 14 are fixedly connected with sealing rings 16, and the outer side of the sealing rings 16 is in contact with the inner side of the nozzle 17.
[0038] Since the second high-pressure hose 14 and the nozzle 17 are rotatable, a sealing ring 16 is fixedly connected to the bottom side of the second high-pressure hose 14 to prevent water from leaking from the connection between the second high-pressure hose 14 and the nozzle 17. The design of the T-groove 15 and the T-ring block 18 can also prevent the nozzle 17 from detaching from the second high-pressure hose 14 and prevent water leakage.
[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
