Description

Technical Field

[0001] This invention belongs to the field of road maintenance machinery technology, and particularly relates to a material rotary crushing device and a crusher. Background Technology

[0002] my country has a large number of manhole covers, among which sinking, potholes and cracks around the manhole covers are some common problems. It is necessary to mill and repair the sinking or damaged asphalt and concrete pavement around the manhole covers to ensure a smooth connection between the manhole covers and the road surface.

[0003] Chinese Patent CN120119535A discloses a road surface breaking device and method for removing manhole covers, comprising: a connecting plate; a support plate; and a sleeve. In this invention, a protective cover is positioned around the manhole cover and pressed downwards against the road surface. Then, a rocker arm drives the frame downwards, causing several sleeves on a triangular plate to fit into corresponding sleeves on the protective cover. This fixes the triangular plate in place. Since the cutter head is connected to the triangular plate, and both the triangular plate and the protective cover are fixed, this method eliminates the need to consider the state of the manhole cover and keeps the cutter head stable during rotation, effectively preventing it from shifting during rotation. The proposed solution involves first cutting the entire surface and then removing it all at once to demolish the road surface around the manhole cover. However, this solution only removes the connection between the damaged road surface and the surrounding road surface on the vertical surface. The connection between the bottom of the damaged road surface and the surrounding road surface remains, making it difficult to remove the damaged road surface in one go using lifting force. Manual demolition is still required, which means that it is not fundamentally different from the traditional solution that relies on manual cutting and then demolition. It cannot reduce labor intensity, cannot improve construction efficiency, and its demolition radius cannot be quickly adjusted, limiting the scope of operation. Summary of the Invention

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Example 1

[0036] like Figure 1 As shown, a material rotary crushing device, arranged on the main unit, includes:

[0037] The main support 1 is connected to a rocker arm 2 for driving it to swing up and down, and a vertical slide rail 11 is provided on it. Support legs 3 are connected to both sides of the main support 1.

[0038] The first housing 4 is slidably connected to the vertical slide rail 11. A first driving member 41 for driving the first housing 4 to slide up and down along the vertical slide rail 11 is provided between the main support 1 and the first housing 4.

[0039] The second housing 5 is rotatably connected to the first housing 4. A rotary drive 6 for driving the second housing 5 to rotate relative to the first housing 4 is provided between the first housing 4 and the second housing 5; and a horizontal slide rail 51 is provided on it.

[0040] A transverse support 7 is slidably connected to a horizontal slide rail 51. A second driving member 71 for driving the transverse support 7 to slide along the horizontal slide rail 51 is provided between the second housing 5 and the transverse support 7. A milling device 8 is installed on it.

[0041] During operation, operating the second drive component 71 can drive the transverse support 7 to slide horizontally, thereby driving the milling device 8 to move horizontally and adjusting the working radius; then, by swinging the swing arm 2, the main support 1 is lowered so that the outrigger 3 contacts the ground to form support; then, operating the first drive component 41 drives the first housing 4 to move downward, so that the first housing 4 drives the milling device 8 to move to a suitable depth; then, operating the rotary drive component 6 drives the second housing 5 to rotate, thereby driving the milling device 8 to rotate.

[0042] The working depth and radius of this application can be quickly adjusted and the structure has good stability, which can meet the operational needs of different working conditions and realize the complete demolition of the road surface in the working area without manual demolition.

[0043] Example 2

[0044] The difference between this embodiment and Embodiment 1 is that two swing arms 2 are arranged parallel to each other between the main support 1 and the main unit. The main support 1 is provided with swing arm mounting holes 12 for mounting the swing arms 2. The main support 1, the main unit, and the two swing arms 2 are hinged to each other and form a parallelogram structure. A main unit telescopic cylinder is arranged between the main unit and the main support 1. One end of the main unit telescopic cylinder is hinged to the main unit, and the other end is hinged to the main support 1 through the main unit telescopic cylinder mounting hole 13. The telescopic movement of the main unit telescopic cylinder can drive the swing arms 2 to rotate, thereby driving the main support 1 to rise and fall.

[0045] like Figure 2 and Figure 3 As shown, the main support 1 has leg mounting holes 14 on both sides. The leg mounting holes 14 are connected to the legs 3 via crossbeams 31, and the height of the legs 3 is adjustable. Specifically, the legs 3 include outer legs 32 and inner legs 33. The outer legs 32 have a sliding inner cavity, and the inner legs 33 are slidably connected to the inner wall of the sliding inner cavity. The inner legs 33 and the outer legs 32 are fixed together by fasteners 34. The bottom of the outer legs 32 is provided with a leg foot 35, which increases the contact area between the legs 3 and the ground, achieving stable support. In this embodiment, several insertion holes are provided along the longitudinal direction on both the inner legs 33 and the outer legs 32. By aligning the insertion holes of different heights, a positioning pin can be inserted into the insertion holes to achieve fixation.

[0046] like Figure 4 As shown, the first box 4 includes vertical wall panels and horizontal wall panels, which are connected by a triangular plate, thus improving the stability of the first box 4 structure.

A first housing 4 is connected to the outer ring of the slewing bearing, and a second housing 5 is connected to the inner ring of the slewing bearing. When the drive motor operates, it can drive the second housing 5 to rotate via the slewing bearing, thereby causing the milling device 8 to rotate one revolution to achieve material crushing. It also includes a central rotating body 61 that cooperates with the slewing bearing.

[0048] like Figure 4 , Figure 5 and Figure 6 As shown, the first housing 4 is provided with a first U-shaped slide groove 42, and the vertical slide rail 11 is slidably connected along the inner wall of the first U-shaped slide groove 42; and / or, the transverse support 7 is provided with a second U-shaped slide groove 72, and the horizontal slide rail 51 is slidably connected along the inner wall of the second U-shaped slide groove. In this embodiment, nylon sliders 74 are arranged on the inner walls of the first U-shaped slide groove 42 and / or the second U-shaped slide groove 72. The friction during the sliding process can be reduced by setting the nylon sliders 74.

[0049] In this embodiment, the first driving component 41 includes a first telescopic cylinder, one end of which is connected to mounting hole 15 on the main support 1, and the other end is connected to mounting hole 43 on the first housing 4; the second driving component 71 includes a second telescopic cylinder, one end of which is connected to mounting hole 52 on the second housing 5, and the other end is connected to mounting hole 73 on the transverse support 7. The extension and retraction of the first telescopic cylinder can drive the first housing 4 to move up and down, and the movement of the second telescopic cylinder can drive the transverse support 7 to move horizontally.

[0050] The present invention provides a material rotary crusher, wherein the above-mentioned material rotary crushing device is arranged on the main unit.
