Problems solved by technology

Existing milling machines and tunneling machines are suitable for medium and low hardness rock formations and minerals, etc. When encountering medium and high hardness rock formations, the milling will not work or the efficiency will be low, and the cutting teeth will be worn out, so the applicable occasions are greatly restricted.

Embodiment 1

[0020] Example 1, such as figure 1 As shown, the high-frequency vibration longitudinal milling head of the present invention comprises a longitudinal milling head 2, a milling head seat 12, a milling body 10, a cutting motor 4, a gearbox 3, and the milling head seat 12 is mounted on the milling body 10. One end, the other end of the milling machine body 10 is provided with a connecting seat 7, which can be connected with the excavator bucket pin. The cutting motor 4 and the gearbox 3 are installed on the milling head base 12, the longitudinal milling head 2 is provided with a milling pick 1, and the top rotating shaft of the longitudinal milling head 2 is installed on the milling head base 12 and connected with the gearbox 3 The output end is connected, the input end of the gearbox 3 is connected with the cutting motor 4; the vibration box 5 is fixedly installed above the milling and digging head seat 12, and the vibration box 5 is placed in the milling and digging body 10, an...

Embodiment 2

[0023] Example 2, such as figure 2 As shown, the structure of the high-frequency vibration vertical milling head of this example is basically the same as that of Embodiment 1, except that the vibration box 5 used is an in-line four-eccentric wheel vibration box (its structure is a prior art, see Chinese patent application No.: 2013103465294, the name of the invention is the in-line eccentric wheel vibration mechanism), the vibration box can obtain greater vibration impact force. No vibration-damping rubber may be provided between the milling headstock 12 and the milling machine body 10 .

Embodiment 3

[0024] Example 3, such as figure 2 As shown, the high-frequency vibration longitudinal milling head of this example can be applied to some special occasions, and its structure is basically the same as that of Embodiment 1, except that the vibration box used is installed on the side of the milling head seat 12, and the vibration box adopts A single eccentric wheel vibrating box 15 integrated with a single eccentric wheel or eccentric block, a vibration-damping rubber 9 is provided between the milling head base 12 and the side wall of the milling machine body 10, and a vibration damping rubber 9 is provided between the milling head base 12 and the top of the milling machine body 10 Air spring 8 is provided. The vibration motor 6 drives the vibration box 15 with a single eccentric wheel, and makes the eccentric vibration force in a circular shape during the rotation, thereby driving the milling head 2 to swing in a circular shape, unlike the linear repeated vibration force descr...

Abstract

The invention discloses a high-frequency vibration longitudinal milling digging head, and a milling digging machine and a heading machine with the high-frequency vibration longitudinal milling digging head. A milling digging head seat of the high-frequency vibration longitudinal milling digging head used by the milling digging machine and the heading machine is arranged at one end of a milling digging machine body; the other end of the milling digging machine body is provided with a connecting seat; a cutting motor and a gearbox are arranged on the milling digging head seat; milling digging cutting teeth are arranged on the longitudinal milling digging head; a rotating shaft arranged on the top of the longitudinal milling digging head is arranged on the milling digging head seat and is connected with the output end of the gearbox; the input end of the gearbox is connected with the cutting motor; a vibration box body is arranged above the milling digging head seat; and the vibration box body outputs high-frequency vibration force to the milling digging head seat, so that the longitudinal milling digging head realizes self rotation movement and can also realize high-speed repeated vibration movement. The longitudinal milling digging head is combined with the vibration box body; the rotation movement of the longitudinal milling digging head can be realized, and the high-frequency repeated vibration can also be performed at the same time; and the cutting teeth on the milling digging head exerts impact and cutting composite acting force on contact materials, so that hard rock can be easily crushed.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to a high-frequency vibration longitudinal milling head and a milling machine and a tunneling machine provided with the milling head. Background technique [0002] The milling machine is a hydraulic attachment used in conjunction with the excavator, and can be widely used in tunnels, ditches, engineering construction, rock excavation and other construction fields. It has the advantages of high efficiency, precision and low cost. According to the arrangement structure of the milling head, it can be divided into two basic types: horizontal milling machine and longitudinal milling machine. The prior art has many countries and products of various sizes and models in use. The roadheader is similar to the milling machine installed on a special chassis. It is a complete vehicle equipment integrating cutting, loading, walking, and operating functions. It is mainly used for c...
