Description

Technical Field

[0001] This utility model relates to the field of road maintenance equipment technology, specifically a road grooving machine with a centrally located cutting mechanism. Background Technology

[0002] A road grooving machine is an engineering device used to pre-cut expansion joints in concrete, asphalt, and other road surfaces. It cuts the road surface with high-speed rotating blades to form neat grooves, preventing cracking caused by thermal expansion and contraction, and ensuring the durability and smoothness of the road surface.

[0003] Traditional road grooving machines typically place the cutting mechanism at the edge of the machine body. This arrangement is primarily for assembly and maintenance purposes. As the most prone to failure structure in the machine body, the cutting mechanism requires regular maintenance. The edge-mounted cutting mechanism facilitates the disassembly and installation of cutting components, eliminating the need to disassemble the entire machine structure during maintenance.

[0004] However, the cutting mechanism accounts for a large proportion of the weight of the entire grooving machine. Placing the cutting mechanism at the edge will cause the center of gravity to be off-center. Especially when working on bumpy roads, the overall balance may be lost due to factors such as shaking during the grooving process, resulting in a decrease in grooving accuracy and even the risk of tipping over and causing danger. In addition, the front cutting mechanism is simply wrapped, which can easily cause sand and gravel to fly and blade damage during construction, posing a safety hazard. Utility Model Content

By optimizing the machine's structural layout, the cutting mechanism is positioned at the center of the chassis, and a stable chassis layout is constructed in conjunction with a dust removal mechanism and a support frame, significantly improving the stability and operational safety of the grooving machine.

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the structure of the cutting mechanism and the structure of the central control module.

[0026] Example 1

[0027] like Figure 1 As shown, a road grooving machine with a centrally located cutting mechanism includes a chassis, a support, a cutting mechanism, and a dust removal mechanism.

[0028] The chassis includes two main beams 1 and multiple crossbeams 2 for connecting the two main beams 1. The two main beams 1 are arranged in parallel, and the crossbeams 2 are fixedly connected to the main beams 1. The two main beams 1 and the crossbeams 2 form a central space.

[0029] The bracket is set in the central space and is fixedly connected to the main beam 1. The mounting plate 14 of the bracket is used to support the cutting mechanism. The mounting plate 14 can rotate around the rotating shaft 11 to adjust the height of the cutting mechanism from the ground.

[0030] The cutting mechanism includes a cutting blade 4 for cutting the road surface, a cutter head 5 for mounting the cutting blade 4, and a motor 6 for driving the cutter head 5. The cutting blade 4 has evenly distributed cutting teeth on its periphery. The cutter head 5 is fixedly mounted with multiple mounting lugs 26 by mounting bolts 25. The cutting blade 4 is fixed to the mounting lugs 26 by a cutting shaft 27.

[0031] The dust removal mechanism includes a turbine fan 7 for generating negative pressure airflow, a dust collection cylinder 8 connected to the turbine fan 7 via a hose, and a dust removal hood 9 located near the cutter head 5. The dust collection cylinder 8 is equipped with a multi-stage filtration system.

[0032] The working principle of this embodiment is that the chassis adopts a high-strength frame structure, and a central space is formed in the center of the frame structure. By integrating the cutting mechanism into the central space of the chassis, the center of gravity of the equipment is kept in the center, thereby significantly improving the operational stability. In addition, this setting also facilitates cable management. The cutting mechanism includes a bracket, a cutting blade 4, a cutter head, and an engine 6. Precise installation ensures that the cutting blade 4 is perpendicular to the ground. Furthermore, the grooving machine also integrates a dust removal mechanism to remove sand and gravel, reducing the environmental pollution caused by grooving operations. This design effectively solves the instability of traditional equipment while reducing pollution and improving the working environment.

[0033] Example 2

[0034] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: the bracket includes two adapter plates 10 fixedly mounted on the chassis. The adapter plates 10 are made of steel and are bolted to the main beam 1 of the chassis. A cylindrical rotating shaft 11 and a rectangular bearing plate 12 are fixedly connected between the two adapter plates 10. The two ends of the rotating shaft 11 are fixedly connected to the arc ends of the adapter plates 10. A mounting base 13 is rotatably connected to the middle of the rotating shaft 11, and the mounting base 13 can rotate around the rotating shaft 11. A mounting plate 14 for mounting the engine 6 is fixedly connected to the mounting base 13. During the rotation and descent of the mounting plate 14 around the rotating shaft 11, the bottom plane of the mounting plate 14 can completely fit against the bearing plate 12 below, forming a stable support structure. Two parallel trapezoidal protective plates 15 are also vertically welded to both sides of the mounting plate 14. The two protective plates 15 and the mounting plate 14 form a U-shaped protective space, which can accommodate the cutter head 5.

[0035] Example 3

[0036] This embodiment is an improvement on embodiment 2. Its main structure is the same as embodiment 2, but the improvement lies in the following: a reinforcing plate 16 is vertically fixed to the upper surface of the mounting plate 14. The reinforcing plate 16 is a long strip of steel plate with screw holes on its surface. These screw holes, in conjunction with bolts, are used to reinforce and fix the engine 6. The reinforcing plate 16 not only effectively enhances the structural strength of the mounting plate 14, preventing vibration and deformation during engine 6 operation, but also improves the installation stability of the engine 6 through multi-point fixing.

[0037] Example 4

[0038] This embodiment is an improvement on embodiment 2. Its main structure is the same as embodiment 2, but the improvement lies in that the cutting mechanism is installed within the protective space formed between the two protective plates 15. The cutting mechanism includes a horizontally positioned central shaft 3, which is rotatably supported on the two protective plates 15 via bearing seats 28. Two parallel disc-shaped cutter heads 5 are fixedly mounted at the center of the central shaft 3. Multiple mounting lugs 26 are distributed around the outer circumference of each cutter head 5. The mounting lugs fix a cutter shaft 27 between the two cutter heads 5 using mounting bolts 25. The axis of the cutter shaft 27 is parallel to the axis of the central shaft 3. A cutting blade 4 is fixedly mounted on each cutter shaft 27.

[0039] Example 5

[0040] This embodiment is an improvement on embodiment 4. Its main structure is the same as that of embodiment 4. The improvement is that the cutting blade 4 is made of alloy and is fixedly installed in the gap of the blade disc 5 by bolts. The edge of the cutting blade 4 extends out from the gap between the two blade discs 5. The cutting blade 6 has multiple cutting teeth on its periphery. This structural design enables the cutting blade 4 to generate multi-stage shearing and tearing action when rotating, which significantly improves the adaptability to different materials and the cutting efficiency.

[0041] Example 6

[0042] This embodiment is an improvement on embodiment 4. Its main structure is the same as that of embodiment 4. The improvement is that: one end of the central shaft 3 is fixedly fitted with a driven pulley 17 by a key connection; the engine 6 is fixed to the mounting plate 14, the engine 6 drives the driving pulley 18, and the driving pulley 18 and the driven pulley 17 are connected by a multi-wedge belt.

[0043] Example 7

[0044] This embodiment is an improvement on embodiment 4. Its main structure is the same as that of embodiment 4. The improvement is that the dust collection cylinder 8 is fixedly installed on the reinforcing rib of the chassis by bolts. The top of the dust collection cylinder 8 is provided with an air outlet 19 and the middle of the dust collection cylinder 8 is provided with an air inlet 20. The air outlet 19 is connected to the turbine fan 7 through a first flexible hose, and the air inlet 20 is connected to the dust removal hood 10 through a second flexible hose. The dust removal hood 10 is set on the chassis near the cutting blade 4.

[0045] Example 8

[0046] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that an adjustable handle frame is added to the front end of the chassis. The handle frame includes two support rods 21. The two support rods 21 are arranged in parallel and are rotatably connected to the chassis through a connecting shaft 24, so that the angle of the support rods 21 can be flexibly adjusted according to the usage requirements. Each of the two support rods 21 is fixedly installed with a handle 22, and the two support rods 21 are connected to each other through a connecting rod 23.

[0047] Example 9

[0048] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that the main beam 1 adopts a U-shaped beam structure and the main beam 1 is provided with a cable tray.

[0049] The chassis uses two 200*50 U-shaped beams as main beams 1, and several cross beams 2 are connected between the two main beams 1, which greatly reduces the weight required for the chassis. The hollow tube inside the main beams 1 is conducive to the wiring of electrical control, while the cross beams 2 reinforce the central chamber, making it more resistant to bending and torsion.
