Description

Technical Field

[0001] This invention relates to the field of stone crushing technology, and specifically to a stone crushing machine. Background Technology

[0002] Cast-in-place asphalt mixture pavements have low porosity and smooth surfaces, making them difficult to bond with the upper pavement structure to form strength. Therefore, when cast-in-place asphalt mixtures are used as a protective layer, pre-mixed aggregate needs to be spread to enhance the shear strength between the protective layer and the wearing course.

[0003] When spreading crushed stone, a specialized spreader is required. After the crushed stone is laid, a compaction device is used to embed it into the asphalt surface to a certain depth. The compaction process is typically carried out manually with small steel rollers or using specialized compaction equipment. Manual labor results in low construction efficiency, uneven embedding depth of the pre-mixed crushed stone, and poor embedding effect. Traditional asphalt layer crushed stone compaction equipment is usually of a specific length, requiring segmented processing for large areas, resulting in numerous repetitive operations and low efficiency. Therefore, this paper proposes a crushed stone compaction machine to solve these problems. Summary of the Invention

The compaction assembly includes a tube box and a compaction roller. The outermost tube box is fixedly mounted on the traveling mechanism, and the compaction roller is mounted on the side of the tube box. An adjustment assembly is provided between the tube box and the compaction roller, and the adjustment assembly can adjust the mounting height of the compaction roller.

[0006] In a preferred embodiment, the walking mechanism includes: A walking frame is fixedly installed on one side of the assembly and compaction mechanism, and a walking motor is fixedly installed on the inner side of the walking frame. The drive wheel is rotatably mounted on the walking frame, and the output end of the walking motor is connected to the drive wheel for transmission.

[0007] In a preferred embodiment, a tensioning assembly is fitted between the tensioning wheel and the traveling frame, the tensioning assembly comprising: The tensioning box is fixedly assembled to the side of the walking frame; A tensioning hydraulic cylinder is fixedly assembled inside the tensioning box. A slider is driven at the output end of the tensioning hydraulic cylinder. The slider is slidably assembled inside the tensioning box and is rotatably connected to the tensioning wheel.

[0008] In a preferred embodiment, an elastic telescopic rod is fixedly connected to the output end of the tensioning hydraulic cylinder, and the elastic telescopic rod is fixedly connected to the slider.

[0009] In a preferred embodiment, a plurality of evenly distributed drag chain wheels and support rollers are rotatably connected to the upper and lower sides of the walking frame, and both the drag chain wheels and the support rollers are connected to the rubber track drive.

[0010] In a preferred embodiment, the adjustment component includes: A rolling frame is hinged to the side of the pipe box, and the rolling roller is rotatably assembled inside the rolling frame; A hydraulic cylinder is hinged to the side of the pipe box, and the output end of the hydraulic cylinder is hinged to the rolling frame. A spray pipe is fixedly installed on the inner side of the rolling frame, and the spray pipe is equipped with several evenly distributed nozzles.

[0011] In a preferred embodiment, the assembly component includes: The connecting pipe ring is fixedly installed at one end of the pipe box opening, and locking grooves are provided on both the upper and lower sides of the other end of the pipe box opening; A bidirectional threaded rod is rotatably mounted on the inner side of the connecting ring. Threaded blocks are rotatably mounted on both sides of the bidirectional threaded rod. The threaded blocks are slidably mounted on the inner side of the connecting ring.

Multiple sets of compaction components are connected in series through assembly components, allowing the compaction width to be flexibly adjusted according to actual needs, making it highly adaptable.

[0016] In the assembled components, the connecting ring and the locking groove at the opening end of the pipe box can slide together. When the bidirectional threaded rod rotates, it drives the threaded blocks on both sides to slide inside the connecting ring, and then pushes the abutment block out of the groove through the connecting rod to abut against the locking groove of the adjacent pipe box, realizing a quick and detachable fixed connection between adjacent compaction components. Compared with traditional bolt, pin or welding connection methods, installation and disassembly are more convenient and efficient. It can also effectively ensure that the upper and lower surfaces of each assembled pipe box are flush, improving the overall structural stability and operating accuracy of the equipment.

Detailed Implementation

[0019] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0021] Example: like Figure 1-6 As shown, this embodiment provides a stone crushing and rolling mill, comprising: The main control box 1 and two walking mechanisms are provided. The main control box 1 is mounted on one of the walking mechanisms. An assembly and compaction mechanism is fixedly connected between the two walking mechanisms. The two walking mechanisms can jointly drive the assembly and compaction mechanism between them to move. The assembly and compaction mechanism includes multiple sets of compaction components, which are connected in series. Adjacent compaction components are detachably and fixedly connected, and assembly components are provided between adjacent compaction components. The walking mechanism includes: The traveling frame 11 is fixedly installed on one side of the assembly and compaction mechanism. The traveling motor 111 is fixedly installed inside the traveling frame 11. The drive wheel 112 is rotatably assembled on the traveling frame 11. The output end of the traveling motor 111 is connected to the drive wheel 112 for transmission. The traveling frame 11 is used to support several components in the traveling mechanism. The traveling motor 111 provides the traveling power for the traveling mechanism.

[0022] Tensioner 113 is rotatably mounted on the traveling frame 11. A rubber track 114 is connected between the drive wheel 112 and tensioner 113. When the traveling motor 111 starts, it drives the drive wheel 112 to rotate. Since the rubber track 114 is connected between the drive wheel 112 and tensioner 113, the rotation of the drive wheel 112 drives the rubber track 114 to move. A tensioning assembly is mounted between the tensioner 113 and the traveling frame 11. The tensioning assembly includes: Tensioning box 1131 is fixedly mounted on the side of walking frame 11; tensioning hydraulic cylinder 1132 is fixedly mounted inside tensioning box 1131, and a slider 1133 is driven at the output end of tensioning hydraulic cylinder 1132. The slider 1133 is slidably mounted inside tensioning box 1131 and is rotatably connected to tensioning wheel 113. The slider 1133 can be adjusted to slide inside tensioning box 1131 by tensioning hydraulic cylinder 1132, thereby pushing tensioning wheel 113 to squeeze rubber track 114, making rubber track 114 taut, so that drive wheel 112 and tensioning wheel 113 can be stably transmitted through rubber track 114. An elastic telescopic rod 1134 is fixedly connected to the output end of the tensioning hydraulic cylinder 1132, and the elastic telescopic rod 1134 is fixedly connected to the slider 1133. The elastic telescopic rod 1134 can buffer the rubber track 114, expand the output range of the tensioning hydraulic cylinder 1132, and prevent the rubber track 114 from being too tight or too loose.

[0023] The upper and lower sides of the traveling frame 11 are respectively rotatably connected to several evenly distributed drag chain rollers 115 and support rollers 116, both of which are driven by the rubber track 114. The drag chain rollers 115 support the upper part of the rubber track 114, preventing the rubber track 114 from sagging excessively and reducing wear; while the support rollers 116 bear the weight of the equipment and transfer the weight to the rubber track 114, enabling the equipment to travel smoothly.

[0024] The compaction assembly includes a tube box 12 and compaction rollers 121. The outermost tube box 12 is fixedly mounted to the traveling mechanism, and the compaction rollers 121 are mounted on the side of the tube box 12. An adjustment assembly is provided between the tube box 12 and the compaction rollers 121 to adjust the mounting height of the compaction rollers 121. Each tube box 12 is equipped with two compaction rollers 121, which are symmetrically arranged on both sides of the tube box 12. The symmetrical arrangement of the compaction rollers 121 on both sides of the tube box 12 helps to balance the weight of the equipment, making the center of gravity of the equipment more central. Furthermore, the presence of compaction rollers 121 on both sides allows for double compaction of the crushed stone, improving the compaction effect of the compaction rollers 121. The tube box 12 has at least two width dimensions for use in assembling roads of different widths.

[0025] The adjustment components include: A compaction frame 14 is hinged to the side of the casing 12, and a compaction roller 121 is rotatably mounted inside the compaction frame 14. A hydraulic cylinder 141 is also hinged to the side of the casing 12, and its output end is hinged to the compaction frame 14. Activating the hydraulic cylinder 141 adjusts the angle of the compaction frame 14 and the height of the compaction roller 121, thus adapting to various road surface heights.

[0026] A spray pipe 142 is fixedly installed inside the compaction frame 14, and the spray pipe 142 is equipped with several evenly distributed nozzles 143. The spray pipe 142 can be connected to a specially designed anti-adhesion agent storage tank and conveying pipeline. Through the nozzles 143, an appropriate amount of anti-adhesion agent can be sprayed onto the surface of the compaction roller 121 in real time to form a protective film, effectively preventing asphalt mixture from adhering to the surface of the compaction roller 121.

[0027] The assembly components include: The connecting pipe ring 13 is fixedly installed at one end of the opening of the pipe box 12, and locking grooves 131 are provided on the upper and lower sides of the other end of the opening of the pipe box 12. A bidirectional threaded rod 132 is rotatably mounted inside the connecting pipe ring 13. Threaded blocks 133 are rotatably mounted on both sides of the bidirectional threaded rod 132. The threaded blocks 133 are slidably mounted inside the connecting pipe ring 13. Connecting rods 134 are hinged to the upper and lower sides of the two threaded blocks 133. Abutment blocks 135, which slidably match the locking groove 131, are hinged between the upper and lower connecting rods 134 on the same side. Grooves 136 are provided on both the upper and lower sides of the connecting pipe ring 13. By rotating the bidirectional threaded rod 132, the two threaded blocks 133 can be adjusted to slide towards or away from each other, thereby causing the abutment blocks 135 on the upper and lower sides to move towards or away from each other, thus locking adjacent pipe boxes 12 in conjunction with the locking groove 131. Furthermore, after the abutment blocks 135, which move away from each other, abut against the inner wall of the pipe box 12, the levelness between adjacent pipe boxes 12 can be adjusted, making the connection between adjacent pipe boxes 12 more centered and aligned, thus facilitating the adjustment of the height of several compaction rollers 121 and improving the compaction effect.

[0028] The threaded block 133 is slidably assembled inside the connecting pipe ring 13. It can fix a slide rod inside the connecting pipe ring 13 and make the slide rod pass through the threaded block 133, thereby ensuring the sliding direction and sliding stability of the threaded block 133.

[0029] A worm gear 15 is fixedly mounted in the middle of the bidirectional threaded rod 132, and a worm 151 that meshes with the worm gear 15 is rotatably mounted on the inner side of the connecting ring 13. The cooperation between the worm gear 15 and the worm 151 can prevent reverse transmission and ensure structural stability.

[0030] The tube box 12 is fixedly equipped with a motor box 152, which contains a brake servo motor and a right-angle reducer. The output end of the brake servo motor is connected to the input end of the right-angle reducer, and the output end of the right-angle reducer is connected to the worm gear 151. The right-angle reducer can stably reduce the output of the brake servo motor, and even if the brake servo motor is powered off, it still has a brake state, which can improve the overall stability of the equipment. It can also be driven by other power equipment.

[0031] Since the assembly compaction mechanism is composed of multiple compaction components connected in series, the construction width can be quickly adjusted through the assembly components if changes occur. To increase the compaction width, the connecting ring 13 of the new compaction component is inserted into the open end of the adjacent pipe box 12, aligning the abutment block 135 on the connecting ring 13 with the locking groove 131 on the pipe box 12. Then, the brake servo motor in the motor box 152 is started. The output of the brake servo motor is reduced in speed by a right-angle reducer, driving the worm 151 to rotate. The worm 151 meshes with the worm wheel 15 in the middle of the bidirectional threaded rod 132, thereby driving the bidirectional threaded rod 132 to rotate. The threaded blocks 133 on both sides of the bidirectional threaded rod 132 slide towards each other under its influence. The threaded blocks 133 push the abutment block 135 out of the groove 136 through the connecting rod 134 and tightly abut against the locking groove 131, achieving a firm connection and level adjustment between adjacent compaction components, ensuring that each compaction roller 121 is at the same height and works collaboratively.

[0032] The working principle of the embodiments is explained in detail below: When using this equipment to compact freshly laid asphalt layers, the main control box 1 starts the travel motor 111. The output of the travel motor 111 drives the drive wheel 112 to rotate. The drive wheel 112, through the rubber track 114 connected to it, under the tensioning action of the tensioning wheel 113, the support of the drag chain wheel 115 on the upper part of the rubber track, and the load-bearing and transmission of the equipment weight by the support roller 116, drives the entire stone compactor to move in the construction area.

[0033] During movement, if the rubber track 114 becomes loose or too tight, the output end of the tensioning hydraulic cylinder 1132 pushes the slider 1133 to slide in the tensioning box 1131 through the elastic telescopic rod 1134, thereby driving the tensioning wheel 113 to move and adjust the tension of the rubber track 114. The elastic telescopic rod 1134 can also play a good buffering role to prevent the rubber track 114 from being damaged by sudden external impact.

[0034] During preparation for construction in the construction area, based on the thickness of the asphalt layer and the size of the crushed stone particles, the main control box 1 controls the hydraulic cylinder 141 to move, causing the output end of the hydraulic cylinder 141 to extend and retract, driving the roller frame 14, which is hinged to it, to rotate around the hinge point between it and the pipe box 12. This, in turn, adjusts the height of the roller 121 mounted inside the roller frame 14, so that the roller 121 reaches the appropriate rolling position. Subsequently, the spray pipe 142 is activated, causing it to evenly spray an anti-adhesion agent onto the surface of the roller 121 through the nozzle 143, forming a protective film to prevent the asphalt mixture from adhering to the roller 121 during rolling, affecting the rolling effect and the cleanliness of the roller.

[0035] Next, the main control box 1 controls the assembly and compaction mechanism to start working. As the traveling mechanism moves slowly, the compaction rollers 121 arranged symmetrically on both sides of the tube box 12 fully compact the stone asphalt layer below. The two compaction rollers 121 can continuously squeeze the crushed stone in the same area twice, which significantly improves the compaction density.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
