[0003]
After the existing excavator has dug materials such as soil, silt and stones, the bucket is raised and moved to the transport vehicle or stockyard. During the transfer process, the materials in the bucket are piled too high and easy Falling, and a lot of dust will be generated during the falling process
If the height of the material accumulation does not exceed the bucket, the soil or sediment in the bucket is easily blown out of the bucket by the wind when there is wind or the excavator is transported too fast, increasing the content of dust and particles in the air, which is not Conducive to environmental protection

Embodiment
[0033] Example: such as Figure 1-8 As shown, a large-scale backhoe hydraulic excavator based on reaction force for dust reduction and anti-dropping includes an excavator main body 1, a water storage tank 2, and a bucket 10; the excavator main body 1 is used to control the movement and excavation of the excavator, and the excavator A water storage tank 2 is arranged on one side of the main body 1, and a water pump 3 is arranged inside the water storage tank 2 for delivering the water in the water storage tank 2 to required components. An excavator arm 5 is arranged on the side adjacent to the excavator main body 1 and the water storage tank 2, a first arm 6 is arranged above the excavator arm 5, and a second arm 7 is arranged below the first arm 6. The bucket 10 is used to excavate materials, load them into vehicles, etc.; the bucket 10 is hinged under the arm 5 of the excavator, and is used for excavating and transporting materials such as sand, soil, and gravel. A telescopi...

The invention discloses a dust-falling and anti-falling large backhoe hydraulic excavator based on counter-acting force, which belongs to the technical field of excavator accessories and comprises an excavator main body, a water storage tank and a bucket. A water storage tank is arranged on one side of the excavator body, a bucket is hinged to the lower portion of an excavator arm of the excavator body, a metal ball is arranged in the bucket, telescopic bucket teeth are connected to the upper portion of one side of the bucket, a scraper is arranged at the front end of the bucket and tightly attached to the telescopic bucket teeth in a surrounding mode, and a bucket movable cover plate is hung above the bucket. And the bucket movable cover plate is provided with a sprinkler head. The bucket is scientific, reasonable and safe and convenient to use, the movable cover plate of the bucket prevents materials from falling off, manpower for cleaning falling objects in the later period is reduced, raised dust is reduced, and environment protection is facilitated; the rotation of the movable cover plate of the bucket does not need any energy, so that the energy is saved; the metal ball can prevent the movable cover plate of the bucket from blocking excavation of the bucket; the water spraying head can determine the spraying water mist amount according to the wind speed and the dust content in the air, and water resources are saved.
Description
technical field [0001] The invention relates to the technical field of excavator accessories, in particular to a large-scale backhoe hydraulic excavator for dust reduction and drop prevention based on reaction force. Background technique [0002] An excavator is a kind of construction machinery with multiple functions. It is an earth-moving machine that uses a bucket to dig materials and load them into transport vehicles or unload them to stockyards. The excavated materials include soil, coal, silt and other items. The excavator structure mainly includes: power device, working device, slewing mechanism, operating mechanism, transmission mechanism, walking mechanism, etc. The excavator arm and bucket are the main components of the excavator. The arm is lowered and lifted, and the bucket is used to excavate materials. They cooperate with each other to complete the excavation action of the excavator working device. Existing excavator working devices are divided into hydraulic ...
