Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining machinery, specifically to a multi-stage rotary boom and a mine chute dredging vehicle. Background Technology
[0002] As the main transportation channel for ore in mines, mine chutes play a crucial role in the mining process. Blockages in mine chutes can severely disrupt normal mine production. Currently, methods for clearing blocked mine chutes include mechanical prying, drilling and blasting, bamboo-pole-suspended explosive charge blasting, hydrogen balloon-suspended explosive charge blasting, and mining rockets. Among these, the bamboo-pole-suspended explosive charge blasting method involves using a bamboo pole to carry explosives to the blasting area. However, the bamboo pole's shape cannot be altered, and one end extends into the chutes from a fixed position, making it difficult to adjust the angle of the explosives. This can result in the explosives not being placed in the optimal blasting area, affecting the effectiveness of the blasting clearing. Utility Model Content

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] Example 1
[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A multi-stage slewing boom includes: a pitch support assembly, a tilting seat 4 hinged to the pitch support assembly, a drive assembly 5 on the pitch support assembly, the drive assembly 5 being used to drive the tilting seat 4 to rotate on the pitch support assembly to adjust the angle of the tilting seat 4, a rotating member 6 (the rotating member 6 can be a slewing drive) being provided on the side wall of the tilting seat 4 away from the pitch support assembly, and a double telescopic member 7 being provided on the rotating member 6, the rotating member 6 driving the double telescopic member 7 to rotate about the axis of the rotating member 6 as the center.
[0023] It should be noted that the explosive to be placed is installed on the moving end of one of the telescopic components 7 (a clamp can be installed on the moving end of the telescopic component to hold the explosive), and the height of the double telescopic component 7 is raised by the pitch support assembly. At the same time, the drive component 5 drives the flipping seat 4 to rotate, changing the angle of the double telescopic component 7. The rotating component 6 drives the double telescopic component 7 to rotate, so that the explosive on the double telescopic component 7 is aligned with the area to be cleared. The double telescopic component 7 extends, so that the explosive contacts and adheres to the bottom of the ore blocking the mine chute (the explosive is coated with glue). The double telescopic component 7 releases the explosive (the clamp releases the explosive), the boom is reset and removed, and then the explosive is detonated to clear the mine chute.
[0024] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 4 The dual telescopic component 7 includes a first telescopic component 701 (such as a hydraulic cylinder), a sliding platform 702, and a second telescopic component 703 (such as a hydraulic cylinder). The sliding platform 702 is mounted on the rotating end of the rotating component 6 (the sliding platform 702 includes a fixed seat and a movable seat, which are slidably connected, with the fixed seat mounted on the rotating end of the rotating component 6). The first telescopic component 701 is mounted on the side wall of the sliding platform 702 (the first telescopic component 701 is mounted on the side wall of the fixed seat). The movable seat of the sliding platform 702 is connected to the movable end of the first telescopic component 701. The second telescopic component 703 is located on the movable seat of the sliding platform 702. The extension and retraction of the first telescopic component 701 drives the movable seat of the sliding platform 702 to move with the second telescopic component 703. The second telescopic component 703 extends and retracts again on the sliding platform 702, increasing the length of the dual telescopic component 7 and improving the effective height of the boom. Furthermore, the retraction of the dual telescopic component 7 also reduces the space occupied when it retracts, making the boom suitable for movement in confined spaces.
[0025] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 3 The extension and retraction direction of the second telescopic member 703 is collinear with the movement direction of the sliding platform 702, and the movement directions of the two are on the same straight line.

The moving end of the first drive component 3 is hinged to the side wall of the support 201 via a pin. The third telescopic component 202 extends and retracts, so that the height of the tilting seat 4 can be adjusted according to the requirements, and the pitch support assembly can not only adjust the pitch angle, but also adjust the height.
[0029] In this embodiment, as a further optimization, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The flipping seat 4 is hinged to the moving end of the third telescopic member 202; the drive assembly 5 includes a mounting cover 501 and a second drive member 502 hinged inside the mounting cover 501 (the second drive member 502 can be a hydraulic cylinder, and the fixed end of the second drive member 502 is hinged to the inside of the mounting cover 501 by a pin). The mounting cover 501 is located on the moving end of the third telescopic member 202, and the moving end of the second drive member 502 is hinged to the flipping seat 4; by extending and retracting the second drive member 502, the flipping seat 4 is driven to rotate and change its angle.
