Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The first embodiment is as follows:

referring to fig. 1-3, an environment-friendly rammer for building comprises an upper hammer 1 and a lower hammer 6, a plurality of cavities 9 are arranged in the upper hammer 1, a piston 5 is arranged in each cavity 9, a supporting pipe 7 is fixed at the lower end of the piston 5, the lower end of the supporting pipe 7 penetrates through the upper hammer 1 and is fixedly connected with the upper end of the lower hammer 6, the upper end of the piston 5 is elastically connected with the inner top of each cavity 9 through a spring 8, a circular groove 3 is annularly arranged on the side wall of the upper hammer 1, a plurality of folding air bags 10 are bonded in the circular groove 3 at equal intervals in the circumferential direction, dust shielding cloth 21 is bonded between the folding air bags 10, the folding air bags 10 are communicated with the cavities 9 through air pipes 11, piezoelectric ceramic pieces 4 are fixed at the inner tops of the cavities 9, and heating wires 2 electrically connected with the piezoelectric ceramic pieces 4.

In this embodiment, folding gasbag 10 is the arc setting, and folding gasbag 10 wholly slopes down, guarantees that folding gasbag 10 can the downward sloping extend to make hide grey cloth 21 and form umbelliform, better suppression dust diffusion.

In the embodiment, when the upper tamping hammer is installed and works, the lower hammer 6 firstly impacts the ground, at the moment, the upper hammer 6 instantaneously impacts the lower hammer 6 again through inertia, the ground is tamped again, the effect is better, in the process that the upper hammer 1 impacts the lower hammer 6, the piston 5 moves upwards in the cavity 9, the gas in the cavity 9 is squeezed into the folding air bags 10 through the air pipe 11, the folding air bags 10 are inflated and downwards inclined to extend at the same time, the dust shielding cloth 21 is driven to be unfolded to form an umbrella shape, and the dust can be effectively prevented from being diffused into the outside air; when the hammer 1 strikes the hammer 6 down, piston 5 extrudees piezoceramics piece 4, piezoceramics piece 4 electricity generation heats heater strip 2, tamp along with many times, the heating that the heater strip does not stop, can make and get into the gaseous heating in the folding gasbag 10 through trachea 11, the gas inflation that is heated, thereby can make the more quick extension of folding gasbag 10 come, it is more obvious to hide the effect of grey, when wholly rising, can reset piston 5 through spring 8, the gas in the folding gasbag 10 is inhaled back this moment, thereby hide grey cloth 21 and withdraw to the ring channel 3 in, do not influence the decline process next time.

Example two:

referring to fig. 4, the difference between this embodiment and the first embodiment is that a water storage cavity 12 is disposed in the upper hammer 1, a water inlet is disposed at the inner top of the water storage cavity 12, a water outlet is disposed at the inner bottom of the water storage cavity 12, a pressure difference stop valve 14 is installed in the water outlet, an air cavity 13 is disposed in a space below the piston 5 of the cavity 9, an air hole 15 is disposed on a side wall of the abutting pipe 7 located in the air cavity 13, a device cavity 18 is disposed in the lower hammer 6, a lower end of the abutting pipe 7 is communicated with the device cavity 18, a plurality of dust suction holes 17 communicated with the device cavity 18 are uniformly distributed on an outer side wall of the lower hammer 6, a plurality of water discharge holes 19 are disposed at the bottom of the device cavity 18, a water inlet pipe 16 communicated with the device cavity 18 is disposed at an upper end of the lower hammer 6, the water inlet pipe 16 corresponds to the water outlet, a, the diameter of the drain hole 19 is much smaller than the diameter of the inlet pipe 16, and the water in the surface device cavity 18 is quickly lost.

When the upper hammer 1 impacts the lower hammer 6, a water inlet pipe 16 arranged on the lower hammer 6 is inserted into a water outlet pipe and enters the water storage cavity 12, water is introduced into the device cavity 18, because the device cavity 18 has a large volume, instantly-entering water is not enough to fill the device cavity 18, the position of the dust suction pipe 17 is higher than the water level, when the upper hammer 1 is tamped next time and impacts the lower hammer 6, the piston 5 moves upwards, the air cavity 13 increases in volume and starts to suck air through the air hole 15 and the abutting pipe 7, because the process that the upper hammer 1 impacts the lower hammer 6 is very fast, air in the device cavity 18 is instantly sucked to generate negative pressure, at the moment, air is sucked through the water inlet pipe 16 and the dust suction holes, so that dust in the dust shielding cloth 21 is sucked into the device cavity 18, the dust is mixed into the water in the device cavity 18, when the whole body rises, the spring 8 pushes the piston 5 to reset, and at the moment, the air in the air cavity 13 is squeezed into the device, can clear up the mesh of filter screen 20 on the one hand, avoid blockking up, on the other hand improves the atmospheric pressure in the device chamber 18 to make sewage discharge in can be quick from wash port 19, it is worth noting that can offset with ground when lower hammer 6 strikes the ground, be in the jam state with wash port 19, the water in the device chamber 18 can not run off rapidly, rise time is longer, is enough to make inside sewage discharge away.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
