Description

Technical Field

[0001] This utility model relates to the field of stone crushing equipment, specifically a resonant stone crushing equipment for concrete pavement. Background Technology

[0002] In renovation and reconstruction projects of concrete highways, municipal concrete roads, concrete pavements, and concrete expressways, resonant crushing equipment is used. Resonant crushing uses the principle of resonance to cause the old cement concrete pavement to resonate with the crushing machinery, breaking the old cement concrete pavement into a layer of cement concrete aggregate with interlocking upper and lower layers. Therefore, a type of concrete pavement resonant crushing equipment is used.

[0003] Chinese Patent No. CN202323528348.1 discloses a concrete pavement resonant crushing device, which adopts the following technical solution: it includes a machine body, a hammer head is provided at the bottom of the machine body, the hammer head slides back and forth in the vertical direction, and four protective plates are provided on the machine body. The four protective plates are distributed in a rectangular shape and are connected in sequence along the circumference of the hammer head to form a rectangular protective area. The hammer head is always located within the rectangular protective area.

[0004] As can be seen from the above, the hammer head breaks the concrete pavement during its reciprocating vertical movement. The tendency of the flying debris generated by breaking the concrete pavement is blocked by the protective plates on all four sides, causing the flying debris to fall into the rectangular protective area, reducing the probability of accidental injury to operators and surrounding personnel caused by flying debris. However, this case still has the following shortcomings: In the work of breaking concrete pavement, concrete pavement with different heights is often encountered. At this time, it is necessary to adjust the position of the hammer head. The installation and adjustment are often time-consuming and laborious, thus affecting the overall efficiency of the breaking work.

[0005] Therefore, a resonant crushing device for concrete pavement is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies and the need to adjust the position of the hammerhead, this invention proposes a resonant crushing device for concrete pavement.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The concrete pavement resonance crushing equipment of this utility model includes a main body and an adaptation adjustment component; the adaptation adjustment component is installed on the main body, and several first hydraulic cylinders are hinged to one side of the bottom of the main body. The output ends of the several first hydraulic cylinders are respectively movably installed with first piston rods, and one end of the several first piston rods is hinged to a baffle. One side of the baffle is hinged to the main body.

[0008] Preferably, the main body is equipped with a protective frame, the interior of the protective frame is provided with a seat, a searchlight is fixedly installed on the top of the protective frame, and an organism is fixedly installed on the bottom of the protective frame.

[0009] Preferably, four connecting blocks are fixedly installed at the bottom of the machine body, and each of the four connecting blocks has a movable wheel movably installed at its bottom.

[0010] Preferably, a fixing block is fixedly installed on the top of the machine body, and support arms are hinged to both sides of the fixing block, with a hammer head hinged to the other end of the support arm.

[0011] Preferably, a third hydraulic cylinder is hinged to both sides of the fixing block, a third piston rod is movably mounted at the output end of the third hydraulic cylinder, and a support arm is hinged to one end of the third piston rod.

[0012] Preferably, a second hydraulic cylinder is hinged to both sides of the fixing block, a second piston rod is movably mounted on the output end of the second hydraulic cylinder, and a hammer head is hinged to one end of the second piston rod.

[0013] The advantages of this utility model are:

[0014] This invention, through the structural design of the adaptive adjustment component, drives the third hydraulic cylinder to extend and retract the third piston rod at the output end. One end of the third piston rod is hinged to one side of the support arm, thereby causing the support arm to move in a circular motion around the hinge point of the fixed block. The circular motion of the support arm triggers a linkage with the hammer head, adaptively adjusting the hammer head height. Simultaneously, the second hydraulic cylinder is driven to extend and retract the second piston rod, triggering a linkage with the hammer head at one end. As the second piston rod moves, the hammer head moves in a circular motion around the hinge point of the support arm, correspondingly adjusting the hammer head's elevation angle. This achieves the function of motion adjustment, solving the problem of needing to adjust the hammer head's position and improving performance in applications with less limitation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5 As shown, a concrete pavement resonant crushing device includes a main body 1 and an adaptation adjustment component 2. The adaptation adjustment component 2 is equipped with a body 21. Several first hydraulic cylinders 25 are hinged to one side of the bottom of the body 21. First piston rods 26 are movably installed at the output ends of the several first hydraulic cylinders 25. A baffle 24 is hinged to one end of the several first piston rods 26. One side of the baffle 24 is hinged to the body 21.

[0024] During operation, the installation of the baffle 24 facilitates the clearing of gravel and prevents gravel from causing obstruction. When the first hydraulic cylinder 25 is driven, the first piston rod 26 extends and retracts within its inner wall. At this time, the baffle 24 will flip at the connection point of the machine body 21.

[0025] Furthermore, the main body 1 is equipped with a protective frame 11, a seat 12 is provided inside the protective frame 11, a searchlight 13 is fixedly installed on the top of the protective frame 11, and an organism 21 is fixedly installed on the bottom of the protective frame 11.

[0026] During operation, the body 21 provides support for the protective frame 11 on top, ensuring the overall stability during operation.

[0027] Furthermore, four connecting blocks 22 are fixedly installed on the bottom of the body 21, and each of the four connecting blocks 22 has a movable wheel 23 movably installed on its bottom.

[0028] During operation, the installation of the movable wheels 23 facilitates the overall movement and provides strong support for the entire system.

[0029] Furthermore, a fixing block 27 is fixedly installed on the top of the body 21, and support arms 34 are hinged to both sides of the fixing block 27. A hammer head 31 is hinged to the other end of the support arm 34.

[0030] During operation, the support arm 34 is hinged to the fixed block 27, allowing the support arm 34 to perform corresponding circumferential movements, thereby enabling the support arm 34 to move relative to the hammer head 31 hinged to the other end.

[0031] Furthermore, a third hydraulic cylinder 32 is hinged to both sides of the fixed block 27, and a third piston rod 33 is movably installed at the output end of the third hydraulic cylinder 32. A support arm 34 is hinged to one end of the third piston rod 33.

[0032] During operation, the third hydraulic cylinder 32 converts hydraulic energy into mechanical energy to drive the third piston rod 33 to extend and retract. The hinge of one end of the third piston rod 33 to the support arm 34 controls the distance of its movement on the fixed block 27, which is beneficial for controlling the height of the hammer head 31.

[0033] Furthermore, a second hydraulic cylinder 28 is hinged to both sides of the fixed block 27, and a second piston rod 29 is movably installed at the output end of the second hydraulic cylinder 28. A hammer head 31 is hinged to one end of the second piston rod 29.

[0034] When the second hydraulic cylinder 28 is driven to work, the second piston rod 29 will generate a linkage with one side of the hammer head 31, so that the hammer head 31 can move in a circle around the hinge of the support arm 34, thereby controlling the elevation angle of the hammer head 31 and making it easier for the hammer head 31 to perform stone crushing work.

[0035] Working principle: When performing resonant crushing of concrete pavement, the third piston rod 33 at the output end is extended and retracted by driving the third hydraulic cylinder 32. One end of the third piston rod 33 is hinged to one side of the support arm 34, thereby driving the support arm 34 to move in a circular motion around the hinge point of the fixed block 27. The other side of the support arm 34 is hinged to the hammer head 31. The circular motion of the support arm 34 is linked to the hammer head 31, and the height of the hammer head 31 is adjusted adaptively. At the same time, the second hydraulic cylinder 28 is driven to extend and retract the second piston rod 29. One end of the second piston rod 29 is linked to the hammer head 31. With the movement of the second piston rod 29, the hammer head 31 moves in a circular motion around the hinge point of the support arm 34. After the hammer head 31 has finished crushing the stone, the baffle 24 blocks the stone to prevent the stone from obstructing the overall movement path.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
