[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] The utility model provides a spray device for a loader, such as Figure 1As shown, it includes a water supply tank 3, a water inlet pipeline 1, a water return pipeline 2 and a filter assembly 6. The water outlet of the water supply tank 3 is connected to the water inlet end of the water inlet pipeline 1, and the water outlet end of the water inlet pipeline 1 is mounted above the bucket of the loader; a water outlet interface is provided on the bucket, and the water inlet of the water supply tank 3 is connected to the water outlet interface through the water return pipeline 2; a filter assembly 6 is arranged in the water supply tank 3 for filtering and recovering impurities in the water. During transportation, only the water inlet pipeline 1 is connected, and dust is sprayed through the water inlet pipeline 1. During transportation, water mist or water droplets are sprayed into the bucket to combine with water and settle, thereby effectively reducing the amount of dust and reducing pollution to the environment. By spraying, the dust concentration in the working area is reduced, the working environment of the workers is improved, and the harm of dust to the health of the workers is eliminated. When cleaning the bucket, the water inlet pipe 1 and the water return pipe 2 are connected at the same time. Water is supplied to the bucket for cleaning through the water inlet pipe 1. The water return pipe 2 collects the sewage in the bucket. The recovered water is filtered by the filter component 6 and then recycled. The residue or accumulated dirt in the bucket is removed to ensure that the bucket can be filled with materials faster when it is used next time, and the accumulated dirt and residue are prevented from corroding or wearing the coating, edge and internal structure of the bucket, so as to keep the bucket in good condition and extend the service life of the equipment.

[0035] like Figure 2 , 3 As shown in Figure 4, the filter assembly 6 includes a connecting rod 61 and a filter layer 62, and a plurality of filter layers 62 are arranged on the connecting rod 61. During the cleaning process, the recycled water is filtered through multiple layers of the filter assembly 6 to remove impurities in the water, thereby realizing the recycling of the recycled water and saving water resources and cleaning costs. The filter layer 62 is a conical structure that is concave downward. The conical design allows the water to be more evenly distributed when passing through the filter layer 62, thereby increasing the effective filtration area, helping to improve the filtration efficiency, and making it easier to capture and remove impurities and particles in the water. In addition, the conical design allows the water to gradually increase its flow rate when flowing through the filter layer 62, which helps prevent the filter layer 62 from being blocked too quickly in a local area, because the increase in the water flow rate can reduce the accumulation of impurities on the surface of the filter layer 62, thereby extending the service life of the filter assembly 6.

[0036] The water supply tank 3 is open at the top, and a cover 5 is provided at the opening position; the filter assembly 6 is detachably mounted at the bottom of the cover 5. A connecting sleeve 51 is formed at the bottom of the cover 5, and an internal thread is formed in the connecting sleeve 51; an external thread corresponding to the connecting sleeve 51 is formed at the top of the connecting rod 61, and the connecting rod 61 is threadedly connected to the connecting sleeve 51, so that the filter assembly 6 can be replaced after multiple uses.

[0037] A winding mechanism 4 is provided on one side of the water supply tank 3. When the loader is operating, the idle return water pipe 2 can be rolled up by the winding mechanism 4, which is convenient for storing the return water pipe 2 and prevents the return water pipe 2 from being rolled into the wheels and causing accidents. The winding mechanism 4 includes a winding wheel 42 and a winding motor 41. The winding wheel 42 is used to wind up the pipe, and the winding motor 41 is used to drive the winding wheel 42.

[0038] The water outlet interface is arranged at the bottom of the bucket, and the water outlet interface is connected to the return water pipeline 2 in a detachable manner.

[0039] The water outlet interface is provided with a sealing cap, and the water outlet interface is sealed by the sealing cap in the transport state; the water outlet interface is provided with an external thread, and the sealing cap is provided with an internal thread corresponding thereto.

[0040] A return water pump and a water inlet pump are arranged in the water supply tank 3 . The return water pump is arranged above the filter layer 62 , and the water inlet pump is arranged below the filter layer 62 .

[0041] The utility model is used as follows: in the transport state, the water outlet interface on the bucket is closed with a sealing cap, water is pumped into the water inlet pipe 1 through the water inlet pump to spray the bucket to reduce dust, and the return water pipe 2 is rolled up and stored by the winding mechanism 4. When cleaning the bucket, water is pumped into the water inlet pipe 1 through the water inlet pump to rinse the bucket, the return water pipe 2 is connected to the water outlet interface of the bucket, and the return water pump works to pump the sewage in the bucket through the return water pipe 2 into the water supply tank 3, and the waste water is pumped into the water inlet pipe 1 for recycling after being filtered by the filter assembly 6 for multiple layers.
