[0001] The invention relates to the technical field of excavators, and in particular to a bucket with a dust reduction function. Background Art

[0002] With the development of modern mines, construction sites and other engineering operations, dust pollution is becoming increasingly serious. Especially in the process of excavation, loading and unloading, due to the dryness and looseness of materials such as soil and stone, a large amount of dust is generated during the operation, which not only affects the health of the operators, but also has an adverse impact on the surrounding environment. Therefore, in response to this problem, many studies and technologies have developed a variety of dust reduction methods to reduce the dust generated during the operation.

[0017] The beneficial effects of the present invention are:

[0018] 1. High-efficiency dust reduction: The bucket of the present invention can form a water curtain on both sides of the bucket opening through the spray mechanism and water flow diversion design, effectively suppressing the dust generated during the excavation operation. The water flow is evenly sprayed through the extension pipe and the nozzle, and the water flow in the protective shell flows into the diversion groove through the water outlet, further dispersing the diversion to ensure the uniformity and high efficiency of the dust reduction effect.

[0019] 2. Automatic water flow control: The present invention adopts the design of extension pipe, counterweight component, extension component and sealing plug, which can automatically adjust the spraying water flow according to the working state of the bucket (such as excavation, transportation, etc.). When the bucket body opens downward for excavation or material feeding, the extension pipe automatically extends under the action of the counterweight component and starts the nozzle to spray water. When the bucket covers the working surface, the extension component is squeezed, and the sealing plug automatically blocks the opening of the extension pipe, stops the spraying of water flow, and avoids the waste of water resources.

[0020] 3. Water-saving effect: Through the cooperation of the extension tube and the sealing plug, the nozzle will spray water only when dust reduction is needed. When the bucket body opens upward to transport materials, the extension tube automatically retracts under the action of the counterweight component and the installation spring, and the nozzle stops spraying water, avoiding the waste of water resources. This water-saving mechanism greatly improves the utilization efficiency of water resources.

[0021] 4. Strong adaptability: The spray mechanism of the present invention has a simple design and compact structure, and can adapt to the dust reduction needs in different working environments. By adjusting the position of the nozzle and the spraying water flow rate, it can be flexibly adjusted according to the working conditions and needs to ensure the stability and adaptability of the dust reduction effect.

[0022] 5. Easy maintenance: The dust suppression system has a simple structure. The spray housing and extension pipe and other components can be effectively protected by the protective housing, which reduces the damage to the equipment from the external environment and is easy to clean and maintain. At the same time, the design of the spray system enables precise water flow control, reduces dependence on external equipment, and improves work efficiency.

[0023] 6. Environmental protection and economic benefits: The present invention not only effectively reduces environmental pollution and improves working conditions at the workplace by optimizing water flow control and dust reduction methods, but also reduces water resource consumption, thereby achieving the dual goals of environmental protection and economic benefits.

[0024] In summary, the bucket with dust reduction function provided by the present invention can fully save water resources and improve work efficiency while ensuring the dust reduction effect, and can adapt to a variety of working environments. It has significant technical advantages and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In one embodiment, referring to Figures 1 to 6 , a bucket with dust reduction function, comprising a bucket body 1, on which bucket teeth 2 and ear plates 8 are arranged, and the outer wall of the bucket body 1 is provided with a reinforcing component 7, and both sides of the opening of the bucket body 1 are provided with a spray mechanism 4, which is used for spraying dust reduction when the bucket body 1 is opened downward; the spray mechanism 4 includes a spray shell 41 installed on the outer walls of both sides of the bucket body 1, and the spray shell 41 is provided with a through hole 1 arranged at intervals on one side of the opening of the bucket body 1, and an extension pipe 45 is movably arranged inside the through hole 1, and a nozzle 43 is arranged at one end of the extension pipe 45 extending to the outside of the spray shell 41, and a counterweight component 44 is arranged on the side wall of the extension pipe 45, and the counterweight component 44 is connected to the outer wall of the spray shell 41 by installing a spring 11; the spray shell 41 is provided with a protective shell 5 on the side of the opening of the bucket body 1, and the extension pipe 4 5. The nozzles 43 are all located in the protective shell 5. A water outlet 9 is provided on one side wall of the protective shell 5 close to the bucket body 1. The outer walls on both sides of the opening of the bucket body 1 are provided with flow guide grooves 6 arranged at intervals, and the position of the flow guide grooves 6 corresponds to the opening position of the water outlet 9; a through hole 2 is provided on one side wall of the protective shell 5 away from the spray shell 41, and an extension component 10 is arranged at intervals on the side of the counterweight component 44 away from the spray shell 41, and one end of the extension component 10 away from the counterweight component 44 extends to the outside of the protective shell 5 through the through hole 2; a sealing plug 47 is provided on the inner wall of the spray shell 41, and the position of the sealing plug 47 corresponds to the opening position of the extension pipe 45; a water pump 42 is provided on the outer wall of the bucket body 1, and the water outlet end of the water pump 42 is connected to the inside of the spray shell 41 through an extension water pipe.

[0034] When the bucket body 1 opens downward to dig or discharge materials, the extension pipe 45 moves away from the spray shell 41 under the action of its own gravity and the gravity of the counterweight component 44. At this time, the water pump 42 injects water into the spray shell 41, and the water flows through the extension pipe 45 and the nozzle 43 and is sprayed into the protective shell 5. The water in the protective shell 5 flows through the water outlet 9 to the guide groove 6. The guide groove 6 disperses and guides the water flowing out of the water outlet 9, so that the water forms a water curtain on both sides of the opening of the bucket body 1, thereby effectively reducing the dust at the opening of the bucket body 1. As the bucket body 1 digs deeper downward, when the excavation working surface contacts and squeezes the extension component 10, it means that the opening of the bucket body 1 has covered the excavation working surface, and at this time, the spray The dust reduction effect of the water curtain is very small. When the extension component 10 is squeezed and moved into the protective shell 5, it drives the counterweight component 44 and the extension tube 45 to move toward the direction close to the spray shell 41, and the mounting spring 11 is compressed and reset. When the end of the extension component 10 extending to the outside of the protective shell 5 is squeezed into the protective shell 5, the sealing plug 47 blocks the opening of the extension tube 45, that is, the nozzle 43 stops discharging water, thereby saving water. When the bucket body 1 opens upward to transfer the excavated materials, the extension tube 45 moves toward the direction close to the spray shell 41 under the action of the gravity of the counterweight component 44 and the elastic action of the mounting spring 11, until the sealing plug 47 blocks the opening of the extension tube 45, that is, the nozzle 43 stops discharging water, thereby avoiding waste of water resources.

[0035] As a preferred embodiment of the present invention, a limiting side wing 46 is provided at one end of the extension tube 45 extending into the spray shell 41, which is used to limit the movement of the extension tube 45 to prevent the extension tube 45 from excessively moving or deviating from the predetermined working position during operation, thereby ensuring the stability of the spraying system and the accuracy of the dust reduction effect, ensuring the continuity and efficiency of the dust reduction effect, and providing more convenience for maintenance and adjustment of the equipment.

[0036] As a preferred embodiment of the present invention, a side wall of the protective shell 5 close to the opening of the bucket body 1 is inclined. The inclined side wall design can make full use of the effect of gravity, so that the water sprayed by the nozzle 43 quickly converges and flows along the inclined wall, and finally concentrates on the opening of the water outlet 9. Compared with the horizontal or irregular wall design, the inclined structure can reduce the stagnation or dispersion of water flow in the protective shell 5, and significantly improve the water diversion efficiency; the inclined wall can reduce the collision and turbulence of water flow in the protective shell, and ensure that the water flow flows quickly to the water outlet 9 with less energy loss, which can not only ensure the stability and continuity of the water flow, but also avoid uneven spraying or water accumulation caused by turbulence; the water flow is quickly and evenly guided to the water outlet 9 by the inclined wall, further ensuring The water curtain formed by the guide groove 6 is evenly distributed. The uniformity of the water curtain is an important factor in achieving efficient dust reduction, and the design of the inclined wall plays a key role in this regard. It can cover both sides of the opening of the bucket body 1 and effectively suppress the spread of dust. During excavation operations, the water flow may carry a certain amount of mud and other impurities. The inclined wall can make these impurities flow quickly to the water outlet 9 with the water flow to avoid their accumulation inside the protective shell 5. This feature not only improves the self-cleaning property of the system, but also reduces the frequency of cleaning and maintenance, and extends the service life of the equipment. The inclined wall can guide the water flow to move in a certain direction and angle to avoid water splashing back to the opening or other parts of the bucket body 1, thereby improving the working efficiency of the spray system and preventing secondary pollution of the outside of the equipment and the surrounding environment.

[0037] As a preferred embodiment of the present invention, the sealing plug 47 is made of a flexible material, and the outer diameter of the sealing plug 47 is matched with the inner diameter of the opening of one end of the extension tube 45 extending into the spray housing 41 .

[0040] As a preferred embodiment of the present invention, a dust shield 38 is installed inside the dust suction chamber 35 at intervals. The dust shield 38 is inclined. A filter screen 37 is installed inside the dust suction chamber 35. The dust shield 38 is located between the opening of the dust suction hole 32 and the filter screen 37. The dust suction pump 34 is used to evacuate the interior of the dust suction chamber 35. The dust at the opening of the bucket body 1 enters the dust suction chamber 35 with the air flow through the dust suction hole 32. The dust shield 38 blocks large particles of dust entering the dust suction chamber 35, so that the large particles of dust are retained on the inclined surface of the dust shield 38. The filter screen 37 further filters and removes dust from the airflow. The inclined dust shield 38 can divert and preliminarily block the inhaled dust airflow. The inclined design not only helps the dust to slide along the dust shield to the dust collecting chamber 36, but also reduces the direct impact of the dust on the filter screen 37, thereby extending the service life of the filter screen.

[0041] As a preferred embodiment of the present invention, the dust shield plate 38 is located at the top of the dust collecting chamber 36, and a movable cover 39 is provided at the bottom of the dust collecting chamber 36. When the dust suction pump 34 stops working, large particles of dust on the inclined surface of the dust shield plate 38 slide into the dust collecting chamber 36, and the movable cover 39 can be opened to remove the dust collected in the dust collecting chamber 36; the dust suction mechanism 3 forms a complete dust capture, filtration and collection system through the reasonable layout of the dust suction chamber 35, the dust collecting chamber 36, the dust shield plate 38 and the filter screen plate 37, as well as the efficient operation of the dust suction pump 34, which has significant advantages such as high efficiency, durability and environmental friendliness, and provides a more efficient solution for the bucket in a working environment with severe dust pollution.
