In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0057] At present, with the increasing number of underground engineering projects, the complexity of construction environment is also increasing. In the water-rich environment, the high humidity and water flow of the water-rich environment can easily affect the lubrication pipeline, and water can easily enter the lubrication pipeline, causing the lubricating grease to be contaminated. The excavation-anchor integrated machine on the market can only be used in a water-poor environment. Even if it is used in a water-rich environment, other protective measures are needed, which not only increases the cost, but also affects the construction efficiency.

[0058] To overcome the above problems, the embodiment of the present application provides a cutting device and an anchor excavating integrated machine. The cutting device comprises a cutting drum, a cutting boom, a guide and a lubricating device. The cutting boom comprises an arm frame and a connecting piece. One end of the arm frame is connected with the connecting piece, and the other end is connected with the cutting drum. The guide is in sliding connection with the connecting piece.

The lubricating device comprises a first lubricating pipeline and a second lubricating pipeline. Inlets of the first lubricating pipeline and the second lubricating pipeline are connected with an oil supply device. Outlets are separately arranged at two ends of the connecting piece, so as to deliver lubricating oil from the two ends of the connecting piece to between the connecting piece and the guide. When water enters one of the lubricating pipelines to affect lubrication, the other lubricating pipeline can still deliver lubricating oil to between the connecting piece and the guide, so that the filling efficiency of the lubricating oil is higher and the cutting device is more suitable for use in a water-rich environment.

[0069] The second lubricating pipeline 206 comprises a first connecting section 2061 and a second connecting section 2062. The first connecting section 2061 extends along the height direction of the anchor-excavation integrated machine. The second connecting section 2062 is located at the connection between the sleeve 203 and the support plate 204, and the extension direction of the second connecting section 2062 is the same as the extension direction of the sleeve 203. One end of the first connecting section 2061 is connected with the oil supply device, and the other end is in communication with one end of the second connecting section 2062. The other end of the second connecting section 2062 is in communication with the second lubricating hole. The lubricating grease flows from the first connecting section 2061 to the second connecting section 2062 of the second lubricating pipeline 206, and finally flows into the second lubricating hole and is delivered to the cavity between the sleeve 203 and the sliding column 202 for lubrication.

[0070] Preferably, the lubricating grease has good waterproof performance, for example, calcium-based lubricating grease, aluminum-based composite lubricating grease or lithium-based lubricating grease.

The cabinet body is provided with a first accommodating cavity, and various electrical elements 303, such as circuit breakers, relays, contactors, programmable logic controllers, and power modules, are installed inside the first accommodating cavity. The cabinet door is connected to the cabinet body, for example, hinged on one side of the cabinet body. The cabinet door is used to open or close the first accommodating cavity, so as to facilitate the installation, operation, inspection, and maintenance of the electrical elements 303 inside the first accommodating cavity.

[0077] The first seal 304 is installed between the cabinet body and the cabinet door to seal the gap between the cabinet body and the cabinet door. The first seal can be a rubber sealing strip or a gasket to prevent water from entering the first accommodating cavity of the electric control cabinet 301 and causing damage to the electrical elements 303.

[0078] Please refer to Figure 4 and Figure 5 In some embodiments, the electrical assembly 3 includes a junction box 302 and a second seal 305. The junction box 302 includes a box body, a cover plate, and an adapter. The box body is provided with a second accommodating cavity, and the cover plate is detachably connected to the box body to open or close the second accommodating cavity, for example, the cover plate can be installed on the box body by a pin. The adapter is at least partially inside the second accommodating cavity and is used to connect the electrical elements 303 and the external adapter wire. The second seal 305 is installed between the box body and the cover plate to seal the gap between the box body and the cover plate.

[0079] For example, the junction box 302 is installed outside the electric control cabinet 301, and the electrical elements 303 in the junction box 302 and the electric control cabinet 301 are connected to each other by cables. One end of the cable is connected to the electrical elements 303 in the electric control cabinet 301, and the other end is connected to the adapter of the junction box 302 and connected to the adapter wire of the external electrical equipment through the adapter.

[0080] The first seal 304 is installed between the cabinet body and the cabinet door of the electric control cabinet 301, and the second seal 305 is installed between the box body and the cover plate of the junction box 302. The first seal 304 and the second seal 305 can seal the electric control cabinet 301 and the junction box 302 tightly, increase the waterproof performance, and prevent water from entering the electrical elements 303 inside the electric control cabinet 301 in a water-rich environment, causing damage to the electrical elements 303.

The star wheel 402 is located in the loading groove 401, and the hydraulic motor 403 is in driving connection with the star wheel 402. The hydraulic motor 403 drives the star wheel 402 to rotate and push the material in the loading groove 401 to the feeding end of the conveying device 5.

[0083] In a water-rich environment, the hydraulic motor 403 is less affected by water, has a low failure rate, is safe, and improves construction efficiency.

[0084] Please refer to Figure 9 In some embodiments, the rack 1 of the excavating-anchor integrated machine is provided with a track-type walking device 6. The track-type walking device 6 has a large contact area with the ground, so that the excavating-anchor integrated machine can walk on soft, muddy or uneven ground, providing good support and stability.

[0085] The track-type walking device 6 is driven by a driving motor 601 and a speed reducer 602. The driving motor 601 is connected to the track-type walking device 6 through the speed reducer 602. The driving motor 601 generates power and rotates. The speed reducer 602 converts the high-speed low-torque output of the driving motor 601 into low-speed high-torque output. The output shaft of the speed reducer 602 transmits the rotary motion to the driving wheel of the track, and the driving wheel engages with the track to transmit the rotary motion to the track, thereby realizing walking.

[0086] The speed reducer 602 is provided with a one-way air release valve 6021. During the operation of the speed reducer 602, the internal temperature rises, which causes the gas to expand. The one-way air release valve 6021 allows the excess gas to be discharged, preventing the internal pressure from being too high. Since it is one-way designed, the one-way air release valve 6021 can prevent water from entering the interior of the speed reducer 602, avoiding water from causing the speed reducer 602 to malfunction.
