Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a rig of making an uproar falls in stereoplasm ground for highway engineering construction, includes frame 1, pivot 3 and drill bit 6, and the equal fixed mounting in both ends of frame 1 has electric putter 7, and this fixed mode is the spiro union. The electric push rod 7 adopts an electric push rod with the model of TGE, and belongs to the prior art. The electric push rod 7 is composed of a driving motor, a reduction gear, a screw rod, a nut, a guide sleeve, a push rod, a sliding seat, a spring, a shell, a turbine, a micro control switch and the like. The motor drives a pair of screw nuts after being decelerated by the gear. The rotary motion of the motor is changed into linear motion, and the push rod action is completed by utilizing the positive and negative rotation of the motor. By mounting the electric push rod 7, the height of the noise reducer 2 can be adjusted to suit the drill bit 6.

As shown in fig. 1 and 2, the noise reduction device 2 is fixedly mounted at one end of the electric push rod 7 away from the frame 1, and the fixing manner is a screw joint. One end of the rotating shaft 3 is fixedly connected with the drill bit 6 through a screw, the other end of the rotating shaft 3 penetrates through the noise reduction device 2 and the machine frame 1 respectively and is driven to be screwed through a driving device, and the driving device can adopt a motor with the model number of Y90S-2, which is the prior art. The noise reduction device 2 comprises an inner shell 21, a noise reduction layer 22 and an outer shell 23 from inside to outside in sequence, the noise reduction layer 22 is sleeved on the outer side of the inner shell 21, and the outer shell 23 is fixedly connected with the inner shell 21 through threads. Through setting up device 2 of making an uproar to three-layer housing compound mode, the effect that gives sound insulation is better.

As shown in fig. 2 and 3, the inner casing 21 is integrally formed as a stepped circular truncated cone, an annular limiting groove 211, a limiting protrusion 213 and a clamping groove 212 are sequentially formed on the outer side wall of the inner casing 21 from top to bottom, and an internal thread is formed at the top end of the inner casing 21. By arranging the annular limiting groove 211 and the limiting protrusion 213, not only a positioning function can be achieved, but also the noise reduction layer 22 can be limited up and down. And the clamping groove 212 is matched with the shell 23, so that the shell 23 is limited leftwards and rightwards.

As shown in fig. 1 and 2, the noise reduction layer 22 is formed by two semicircular pipe bodies fixedly connected by screws. The outstanding piece 221 that holds that is provided with in the layer 22 both ends of making an uproar falls, fall the inside of layer 22 of making an uproar and offer with spacing protruding 213 assorted constant head tank 222, spacing protruding 213 is pegged graft in constant head tank 222, and falls the inner wall of layer 22 of making an uproar and run through and set up a plurality of holes 223 of making an uproar that fall, all is equipped with in every hole 223 of making an uproar and inhales the sound cotton. Through seting up a plurality of holes 223 of making an uproar and inhaling the sound cotton, not only have certain ventilation effect, can also improve certain syllable-dividing effect.

As shown in fig. 2, a threaded ring 231 integrally formed with the housing 23 is fixedly installed at the top end of the housing 23, a through hole 232 matched with the rotating shaft 3 is formed through the threaded ring 231, and a bearing is fixedly installed inside the rotating shaft 3 by adhesion.
