[0022] Embodiment 1:
[0023] like Figures 1 to 3 As shown, a protective device for an excavator breaker hammer includes a protective cover 1. The protective cover 1 is made of metal material, which is more wear-resistant and durable than rubber material.
[0024] A water tank 2 is provided on the top of the protective cover 1. The water tank 2 surrounds the excavator breaker 3 to form a channel 4 for the excavator breaker 3 to move up and down. The water tank 2 can be set as an annular water tank, and the inner side of the annular water tank forms a channel 4. In this embodiment, two groups of water tanks 2 are provided, and a connecting chain 5 is provided between the two groups of water tanks 2. The connecting chain 5 is connected to the protective cover 1. Specifically, a connecting hole is provided on the top side wall of the protective cover 1, and the connecting chain 5 is connected to the connecting hole through a connecting ring.
[0025] The bottom of the water tank 2 is provided with a spray hole 201 connected to the protective cover 1. The spray hole 201 is a micropore with a diameter of 0.002-0.5 mm. The cross-sectional structure of the spray hole 201 is as follows: Figure 5 When the excavator breaker 3 is not in operation, the water in the spray hole 201 is in a balanced state due to surface tension, and the water in the water tank 2 does not flow out of the spray hole 201; when the excavator breaker 3 is in operation, the balance is broken due to vibration, and the water in the water tank 2 flows out of the spray hole 201, spraying the space in the protective cover 1, playing the role of sprinkling water to reduce dust.
[0026] Preferably, the side wall of the protective cover 1 close to the excavator driver is provided with a plurality of observation holes 102. It is convenient for the driver to accurately locate the position of the breaker, and the small holes can also prevent large stones from flying out.
[0027] Alternatively, the observation hole 102 can be replaced by a window provided on the protective cover 1, and the window can be sealed with a transparent plate, which does not affect the protective function of the protective cover 1 and facilitates observation.
[0028] Embodiment 2: Different from Embodiment 1, a gauze or filter membrane is laid at the bottom of the water tank 2, and the pore size of the gauze and filter membrane is less than 0.4 nm. The surface tension of the water in the gap of the gauze or filter membrane is balanced with gravity, and automatic watering is achieved through mechanical vibration.
[0029] Embodiment 3:
[0030] Different from Example 1 and Example 2, Figure 2 and Figure 4 As shown, the protective cover 1 includes a plurality of conical covers 101 which are nested with each other. In the present embodiment, five groups of conical covers 101 are selected. The conical covers 101 are small at the top and large at the bottom. The conical covers 101 are provided with an inner edge 103 at the upper end and an outer edge 104 at the lower end. Both the inner edge 103 and the outer edge 104 are arranged in a ring shape. The outer edge 104 of the upper conical cover 101 limits the inner edge 103 of the adjacent conical cover 101 located below.
[0031] The conical covers 101 can move up and down relative to each other to adjust the height of the protective cover 1. The lower conical cover 101 moves downward. When the inner edge 102 of the upper end moves to the upper side of the outer edge 104 of the adjacent conical cover 101 above, the lower conical cover 101 cannot move, thereby limiting the position of the lower conical cover 101.
[0032] The conical covers 101 can move relative to each other, so that when the breaker hammer is inserted into the ground to work, the height of the protective cover 1 can be adjusted to prevent the protective cover 1 from being deformed.
