Embodiment 1

[0038] An ultrasonic-assisted high-pressure water jet mixed abrasive spray head, comprising an outer shell 1 and an ultrasonic vibrator 6, the outer shell 1 contains a main channel 11 and a side channel 12, the main channel 11 runs through the outer shell 1, and one end of the main channel 11 is a first The medium inlet, the other end of the main channel 11 is a mixing outlet, the outside of the outer casing 1 communicates with the main channel 11 through the side channel 12, the ultrasonic vibrator 6 can emit ultrasonic waves into the main channel 11, and the emission direction of the ultrasonic vibrator 6 faces the main channel 11. The other end of channel 11, such as figure 1 shown.

[0039] In this embodiment, the main channel 11 is in an upright state, and the side channel 12 is in a horizontal state. The main channel 11 runs through the upper and lower ends of the outer shell 1. The upper end of the main channel 11 is the first medium inlet of the outer shell 1. The main...

Embodiment 2

[0067] This embodiment is a modification of Embodiment 1, and the main difference between this embodiment and Embodiment 1 is that

[0068] The ultrasonic-assisted high-pressure water jet mixed abrasive spray head includes a plurality of ultrasonic vibrators 6, and the plurality of ultrasonic vibrators 6 are located in the annular cavity 14, and the plurality of ultrasonic vibrators 6 are arranged at intervals along the circumferential direction of the annular cavity 14. 6 is connected and fixed to the abrasive material input wear-resistant nozzle pressure head 2. The ultrasonic vibrator 6 includes a piezoelectric ceramic transducer 61, a horn 63 and a water wave enhancement cover 64 connected in sequence. The cross section of the water wave enhancement cover 64 is arc-shaped. The arc-shaped opening faces the mixing outlet; along the axial direction of the outer casing 1, the ultrasonic vibrators 6 correspond to the communication gaps 43 one-to-one, and the side channel 12 is l...

Embodiment 3

[0082] This embodiment is a modification of Embodiment 1, and the main difference between this embodiment and Embodiment 1 is that

[0083] The abrasive material input wear-resistant nozzle head 2 and the abrasive material input wear-resistant nozzle 3 have an integral structure, and can become an integrated abrasive material input wear-resistant nozzle 3 . Abrasive input wear-resistant nozzle pressure head 2 and abrasive material input wear-resistant nozzle 3 are made of the same material, the inner diameter of abrasive material input wear-resistant nozzle pressure head 2 is the same as the inner diameter of abrasive input wear-resistant nozzle 3, and the abrasive nozzle positioning backing ring 4 can be omitted. A plurality of jet grooves 34 are arranged outside the outlet end of the abrasive input wear-resistant nozzle 3, and the plurality of jet grooves 34 are arranged at even intervals along the circumferential direction of the abrasive input wear-resistant nozzle 3, as ...

Abstract

The invention provides an ultrasonic-assisted high-pressure water jet mixed abrasive sprayer and a heading machine, the ultrasonic-assisted high-pressure water jet mixed abrasive sprayer comprises an outer shell (1) and an ultrasonic vibrator (6), a main channel (11) and a side channel (12) are arranged in the outer shell (1), the main channel (11) penetrates through the outer shell (1), one end of the main channel (11) is a first medium inlet, the other end of the main channel (11) is a mixing outlet, the exterior of the outer shell (1) is communicated with the main channel (11) through the side channel (12), the ultrasonic vibrator (6) can emit ultrasonic waves into the main channel (11), and the emitting direction of the ultrasonic vibrator (6) faces the other end of the main channel (11). The ultrasonic-assisted high-pressure water jet mixed abrasive nozzle solves the problems of low efficiency, low impact speed and the like when a high-pressure water jet nozzle is only carried for rock breaking.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment, in particular to an ultrasonic-assisted high-pressure water-jet mixed-abrasive nozzle, and a roadheader containing the ultrasonic-assisted high-pressure water-jet mixed-abrasive nozzle. Background technique [0002] At present, most of the full-face roadheaders in my country are suitable for medium-hard rock to hard rock. Under the propulsion pressure of the propulsion cylinder, the electric motor or hydraulic motor drives the cutterhead to rotate, cutting and compressing the broken rock, and the broken rock is unloaded by the bucket. onto the transport belt. During the process of excavation and rock breaking, the interaction between the hob and the rock produces friction, and the long-term uninterrupted excavation construction, and the construction site is poorly ventilated, the heat accumulated by the friction between the hob and the rock cannot be effectively dissipated, resulting i...
