Description

TECHNICAL FIELD

[0002] In municipal road construction, road brick cutting is one of the core processes, and the existing cutting device has significant defects in actual application. The traditional device lacks effective dust isolation structure, and a large amount of dust generated by cutting directly diffuses to the working environment, which not only pollutes the air but also seriously endangers the respiratory system health of the operators.

[0003] Patent No. CN108465336B discloses a municipal road brick cutting dustproof device, and its working principle is as follows: the device takes a box body as a bearing frame, and an anti-shock support mechanism is formed by a supporting leg, a supporting sleeve and a buffer spring at the lower end; an adjustable height lifting column and an operation table are arranged at the inner bottom of the box body for bearing the road bricks to be cut; a dust suction cover is arranged at the top and connected with a left dust removal box through a suction pipe; a water storage tank cooperates with a negative pressure pump to generate negative pressure in the dust suction cover, and cut dust is sucked into the dust removal box; dust is filtered by a conical filter screen in the dust removal box, and a water spraying ring at the top is supplied with water by a circulating liquid pump to spray the filter screen, and a scraping plate driven by a driving motor scrapes the dust into a collection cylinder to realize collection.

[0004] Although the above-mentioned scheme realizes dust collection and filter screen self-cleaning through the combination of "negative pressure dust collection-filter screen filtering-spraying impurity removal", solves the dust pollution problem, but the impurity removal and support actions are completely independent, the operation table has no automatic impurity removal function, and the attached debris after cutting still needs manual cleaning, and the scheme depends on multiple independent power sources such as negative pressure pump, circulating liquid pump and driving motor, which has high energy consumption and complex structure, and is not suitable for use in municipal road construction site.

[0016] The advantages of this invention application compared to the prior art are:

[0017] 1. This invention application sets up two support structures, a vibration structure, two collection boxes, and two dust covers. Relying on the synergy of the two dust covers, two support structures, vibration structure, and two collection boxes, the gravitational potential energy of the road bricks is converted into support positioning and impurity removal and resetting power. During material feeding, gravity drives the support plate to be positioned horizontally, the resetting component stores energy, and the locking component fixes the vibration component. During cutting, the dust cover closes the area to prevent dust diffusion. After material removal, the resetting component releases energy to push the support plate to tilt, the linkage component synchronously forms a impurity removal gap, and the vibration component starts to assist in the shedding of debris. The debris falls into the collection box through the gap to achieve automatic cleaning, thereby solving the problems of traditional cutting devices that require manual cleaning of debris and easy dust diffusion.

[0018] 2. This invention application sets up a connecting plate and multiple elastic telescopic rods. When feeding materials, the weight of the brick drives the support plate to rotate, squeezing the telescopic rods to deform and store elastic potential energy. After the materials are removed, the telescopic rods release energy to generate driving force, pushing the support plate to rotate to an inclined state. Without an additional driving source, the support plate can switch between two states: horizontal support and inclined impurity removal, thereby achieving energy self-sufficiency for support positioning and impurity removal reset.

[0019] 3. This invention applies for two linkage components. Since the two linkage components are symmetrically distributed at both ends of the rotating shaft, the driving force of the swing arm on the linkage rod is balanced, ensuring that the plate moves smoothly until the support plate rotates to the tilt angle. A uniform gap for debris to fall is formed between the plate and the support plate, providing a channel for the debris to slide off after subsequent vibration and impurity removal. By designing linkage components at both ends of the rotating shaft, the full stroke synchronization of the plate movement and the tilt of the support plate is achieved. Attached Figure Description

[0033] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 12As shown: An automatic dust-proof device for cutting municipal road bricks includes a cutting equipment body 1, a base frame 2, two support structures 3, a vibration structure 4, two collection boxes 5, and two dust covers 6. The two support structures 3 are symmetrically arranged inside the base frame 2. Each support structure 3 includes a support plate 31, a flat plate 32, a reset component 33, and a linkage component 34. The support plate 31 is provided with a rotating shaft 311 that is rotatably connected to the base frame 2. The flat plate 32 is horizontally slidably arranged on the base frame 2. The reset component 33 is located at the bottom of the support plate 31 and is used to drive the support plate 31 to rotate around the rotating shaft 311 and then reset it. The linkage component 34 is connected to the rotating shaft 311. The shaft 311 is linked, and the plate 32 moves horizontally in sync with the rotation of the shaft 311, so that a gap for debris to fall is formed between the support plate 31 and the plate 32; the vibration structure 4 is set at the lower end of the support structure 3, and the vibration structure 4 includes two vibration components 41 and a locking component 42. The vibration components 41 are used to drive the rotating support plate 31 to vibrate, and the locking component 42 is used to lock the vibration components 41; two collection boxes 5 are used to collect the debris that slides off the two support plates 31 respectively; two dust covers 6 are symmetrically arranged on the base frame 2 about the main body 1 of the cutting equipment, and are used to cover the cutting area to seal off the dust.

[0035] The support plate 31 of the support structure 3 is tilted under the natural force of the reset component 33, and the two dust covers 6 are open. The operator places the municipal road brick to be cut on the support area of ​​the base frame 2. The weight of the road brick acts directly on the support plate 31, driving the support plate 31 to rotate around the axis of the pivot 311 connected to the base frame 2 until the support plate 31 rotates to a horizontal position. At this time, the support plate 31 and the plate 32 form a coplanar support surface, jointly supporting the road brick to ensure support stability. At the same time, the rotation of the support plate 31 causes the reset component 33 at the bottom to convert gravitational potential energy into mechanical potential energy and store it. Simultaneously, the locking component 42 applies a locking force to the vibration component 41, keeping the vibration component 41 stationary. Finally, the operator fine-tunes the position of the road brick to ensure that its part to be cut is aligned with the cutting path of the main body 1 of the cutting equipment. Then, the two dust covers 6 are adjusted to the closed position, completely sealing the cutting area. The main body 1 of the cutting equipment is started to cut the road bricks. The dust generated during the cutting process is sealed inside the dust cover 6, effectively preventing the dust from spreading into the working environment. After the cutting is completed, the operator opens the dust cover 6 and removes the two sections of road bricks from the support surface. The locking component 42 simultaneously releases the locking force on the vibration component 41, and the reset component 33 releases the stored mechanical potential energy, pushing the support plate 31 to rotate in the opposite direction around the rotating shaft 311 until the support plate 31 returns to the preset tilt state. During the rotation of the support plate 31, the linkage component 34 linked with its rotating shaft 311 moves synchronously, causing the plate 32 to slide horizontally along the base frame 2, so that a uniform gap for debris to fall is formed between the plate 32 and the rotating and tilting support plate 31. Simultaneously, the vibration component 41 is activated, applying high-frequency vibration to the rotating support plate 31. The vibration force causes the cutting debris adhering to the surface of the support plate 31 to detach. Under the combined action of gravity and vibration, the debris slides down the inclined surface of the support plate 31 and falls directly into the corresponding collection box 5 below through the gap between the plate 32 and the support plate 31, thus achieving automatic debris collection. By converting the gravitational potential energy of the road bricks into support positioning power and debris removal and resetting power, combined with the synchronous action of the linkage component 34 and the vibration component 41, the problems of manual debris cleaning and dust dispersion in traditional cutting devices are solved.

[0036] Reference Figure 4 , Figure 5 and Figure 6 As shown: The reset assembly 33 includes a connecting plate 331 and a plurality of elastic telescopic rods 332; the connecting plate 331 is connected to the base frame 2; the plurality of elastic telescopic rods 332 are arranged at equal intervals along the length direction of the connecting plate 331, and their two ends are rotatably connected to the connecting plate 331 and the support plate 31 respectively. The elastic potential energy released by the elastic telescopic rods 332 pushes the support plate 31 to rotate around the rotating shaft 311 to a preset tilt angle.

[0037] In the initial state of the device, the elastic telescopic rod 332 of the reset assembly 33 is in a naturally extended state, and the support plate 31 maintains an inclined angle under the support of the elastic telescopic rod 332. When the operator places the road brick to be cut on the support area of ​​the base frame 2, the weight of the road brick acts directly on the surface of the support plate 31, driving the support plate 31 to rotate around the pivot 311 connected to the base frame 2. The rotation of the support plate 31 will generate a compressive force on the elastic telescopic rod 332, causing the elastic telescopic rod 332 to contract and undergo elastic deformation along its own axis. The gravitational potential energy of the road brick is transferred to the elastic telescopic rod 332 through the rotation of the support plate 31, and is converted into the elastic potential energy of the elastic telescopic rod 332 and stored stably. After the road brick is cut, the operator removes the cut brick from the support plate 31. At this time, the elastic telescopic rod 332, which is in a compressed state, loses the external force constraint, releases the stored elastic potential energy, and generates an extension driving force along the axial direction of the telescopic rod. The extension driving force is converted into a torque that pushes the support plate 31 to rotate counterclockwise around the pivot 311, driving the support plate 31 to rotate around the pivot 311. Until the support plate 31 rotates to a preset tilt angle under the drive of the telescopic rod, the telescopic rod returns to its natural extended state, the energy is released, and the support plate 31 stably maintains its tilted posture. By setting multiple equally spaced elastic telescopic rods 332, energy self-sufficiency for support positioning and impurity removal / resetting is achieved.

[0038] Reference Figure 5 and Figure 7 As shown: There are two linkage components 34, which are respectively set at both ends of the rotating shaft 311. The linkage component 34 includes a swing arm 341 and a linkage rod 342. The swing arm 341 is connected to the rotating shaft 311 and rotates synchronously with the rotating shaft 311. The two ends of the linkage rod 342 are respectively connected to the swing arm 341 and the plate 32 through a revolute joint. When the rotating shaft 311 rotates, the swing arm 341 drives the linkage rod 342 to push and pull the plate 32 to move.

[0039] When the paving brick to be cut is placed on the support plate 31, the weight of the paving brick drives the support plate 31 to rotate around the pivot 311 to a horizontal position, forming a coplanar support with the plate 32. During this process, the pivot 311 synchronously drives the swing arms 341 at both ends to rotate clockwise. The swing arms 341 pull the linkage rod 342 through the revolute joint. The linkage rod 342 drives the plate 32 to move along the horizontal direction of the base frame 2 towards the support plate 31 until the plate 32 is completely in contact with the horizontal support plate 31, jointly supporting the paving brick. After the paving brick is cut and removed, the reset assembly 33 pushes the support plate 31 to rotate in the opposite direction around the pivot 311 to an inclined position. The reverse rotation of the pivot 311 drives the swing arms 341 at both ends to swing in the opposite direction synchronously. The swing of the swing arms 341 generates a horizontal thrust on the linkage rod 342 through the revolute joint, thereby pushing the plate 32 to move horizontally away from the support plate 31. Because the two linkage components 34 are symmetrically distributed at both ends of the rotating shaft 311, the driving force of the swing arm 341 on the linkage rod 342 is balanced, ensuring that the plate 32 moves smoothly until the support plate 31 rotates to the tilt angle. At this point, a uniform gap for debris to fall is formed between the plate 32 and the support plate 31, providing a channel for the debris from subsequent vibration cleaning to slide off. By designing linkage components 34 at both ends of the rotating shaft 311, the full stroke synchronization of the movement of the plate 32 and the tilting of the support plate 31 is achieved.

[0040] Reference Figure 5 and Figure 7 As shown: The support structure 3 also includes two symmetrically arranged limiting sliding components 35 at the lower end of the plate 32. The limiting sliding component 35 includes a support base 351 and a sliding connection unit. The support base 351 is connected to the base frame 2 to form a rigid support carrier. The sliding connection unit is connected to the plate 32 to guide the movement of the plate 32 so that the gap between the plate 32 and the support plate 31 remains uniform.

[0041] When the paving brick to be cut is placed on the support plate 31, gravity drives the support plate 31 to rotate around the pivot 311 to a horizontal position. The swing arm 341 of the linkage assembly 34 then moves the plate 32 towards the support plate 31 via the linkage rod 342. During this process, two sliding connection units at the lower end of the plate 32 fix the direction of movement of the plate 32, effectively limiting its vertical movement or horizontal shift, ensuring that the plate 32 always maintains a horizontal posture as it approaches the support plate 31. After the paving brick is cut and removed, the reset assembly 33 pushes the support plate 31 to rotate around the pivot 311 to an inclined position. The swing arm 341 then moves the plate 32 away from the support plate 31 via the linkage rod 342 to create a gap for debris to fall. Under the thrust of the linkage rod 342, the plate 32 slides along the two limiting sliding components 35. Therefore, the two ends of the plate 32 always maintain the same moving speed and moving distance, avoiding the tilting or jamming of the plate 32 due to excessive force on one side, thus realizing the synchronous movement and uniform gap control of the two ends of the plate 32.

[0042] Reference Figure 7 and Figure 8 As shown: The sliding connection assembly 352 includes a first guide rod 3521, a first slider 3522, and a first spring 3523; the first guide rod 3521 is arranged along the middle surface perpendicular to the main body 1 of the cutting equipment; the first slider 3522 is slidably arranged on the first guide rod 3521 and connected to the plate 32; the two ends of the first spring 3523 abut against the first slider 3522 and the support seat 351 respectively, providing buffer for the movement of the plate 32 and assisting the plate 32 to reset.

[0043] When the paving brick to be cut is placed on the support plate 31, the weight of the paving brick drives the support plate 31 to rotate around the pivot 311 to a horizontal position. The movement of the plate 32 causes the first slider 3522 at the bottom to slide along the first guide rod 3521 away from the support base 351, and the first spring 3523 is compressed and stores elastic potential energy. After the paving brick is cut and removed, the reset component 33 releases the elastic potential energy, pushing the support plate 31 to rotate in the opposite direction around the pivot 311 to an inclined position. The linkage component 34 then drives the plate 32 to move away from the support plate 31. The first spring 3523 releases its stored elastic potential energy, generating a thrust along the axis of the first guide rod 3521 that acts on the first slider 3522. This thrust, together with the driving force of the linkage component 34, forms a resultant force in the same direction, assisting in pushing the slider to move the plate 32 quickly. This effectively reduces the driving force requirement of the linkage component 34, ensuring that the plate 32, driven by the linkage component 34, quickly and smoothly forms a uniform gap with the support plate 31.

[0044] Reference Figure 4 , Figure 9 and Figure 10As shown: the vibration assembly 41 includes a vibration generating plate 411 and a vibration generating component 412; the vibration generating plate 411 is horizontally disposed at the lower end of the support plate 31; the vibration generating component 412 is disposed at the lower end of the reset assembly 33, and the vibration generating component 412 includes a roller 4121, which rolls along the vibration generating plate 411 to generate vibration.

[0045] The connecting plate 331 is rotatably connected to the roller 4121. After the road brick is cut and removed, the locking component 42 is released, and the reset component 33 pushes the support plate 31 to rotate around the rotating shaft 311 to an inclined state. The roller 4121, which is rotatably connected to the connecting plate 331, rolls along the surface of the vibration generating plate 411. During the rolling process, the roller 4121 moves up and down with the undulation of the texture on the vibration generating plate 411. This displacement is transmitted to the elastic telescopic rod 332 through the connecting plate 331, causing the elastic telescopic rod 332 to generate high-frequency telescopic deformation. The deformation of the elastic telescopic rod 332 directly transmits the vibration to the support plate 31, which is rotatably connected to it. This causes the support plate 31 to generate high-frequency vibration synchronously during the continuous tilting process. The cutting debris attached to the surface of the support plate 31 is detached from the adsorption under the action of vibration and slides down quickly under the gravity guidance of the tilted support plate 31, thereby improving the efficiency and thoroughness of debris cleaning.

[0046] Reference Figure 10 and Figure 11 As shown: the vibration assembly 41 also includes a limiting guide assembly 413, which includes a second guide rod 4131, a second slider 4132 and a third guide rod 4133; the second guide rod 4131 is arranged along the rolling direction parallel to the roller 4121; the second slider 4132 is slidably arranged on the second guide rod 4131; the third guide rod 4133 is vertically arranged at the upper end of the second slider 4132 and is slidably connected to the reset assembly 33.

[0047] After the road bricks are cut and removed, the locking assembly 42 is released, and the elastic telescopic rod 332 releases its potential energy to drive the support plate 31 to rotate. The roller 4121 then rolls along the textured surface of the vibration generating plate 411. As the roller 4121 rolls, its two ends, through the connecting plate 331, drive the corresponding second sliders 4132 to slide synchronously along the second guide rod 4131. The second guide rod 4131 restricts the movement direction of the second sliders 4132, ensuring that the roller 4121 always rolls parallel to the preset trajectory, preventing lateral displacement of the roller 4121 and thus avoiding texture misalignment. When the roller 4121 rolls to a raised part of the texture, it is compressed and lifted upwards, pushing the connecting plate 331 vertically upwards along the third guide rod 4133. When the roller 4121 rolls to a recessed part of the texture, the connecting plate 331, under the action of gravity and the elastic telescopic rod 332, moves vertically downwards along the third guide rod 4133. During this process, the third guide rod 4133 provides guidance for the up-and-down movement of the connecting plate 331, ensuring that the roller 4121 remains in close contact with the vibration generating plate 411 regardless of the undulations of the texture, and will not tilt due to vertical displacement. Based on the horizontal constraint of the second guide rod 4131 on the rolling direction of the roller 4121 and the vertical guidance of the third guide rod 4133 on the undulations of the connecting plate 331, a trajectory control mechanism for the movement of the roller 4121 is established, thereby ensuring that the roller 4121 remains accurately aligned and in close contact with the texture of the vibration generating plate 411 during rolling and up-and-down movements.

[0048] Reference Figure 11 As shown: The limiting guide assembly 413 also includes a second spring 4134, which is sleeved on the second guide rod 4131. The second guide rod 4131 is used to push the second slider 4132 to move along the second guide rod 4131, and the auxiliary support plate 31 rotates to an inclined state.

[0049] When the road brick to be cut is placed on the support plate 31, the connecting plate 331 drives the second slider 4132 to slide along the second guide rod 4131 in a direction away from the center of the base frame 2, and the second spring 4134 is compressed and stores elastic potential energy. After the road brick is cut and removed, the locking component 42 releases the constraint on the vibration component 4, and the second spring 4134 quickly releases the stored elastic potential energy, generating a thrust along the axis of the second guide rod 4131, pushing the second slider 4132 to slide quickly towards the center of the base frame 2. The second spring 4134 stores elastic potential energy when the support plate 31 is horizontally supported, and releases energy to form an auxiliary thrust when the support plate 31 rotates to an inclined state. This force combines with the driving force of the reset component 33, thereby effectively reducing the load on the reset component 33 and ensuring that the support plate 31 rotates quickly and smoothly to the preset tilt angle.

[0050] Reference Figure 9 and Figure 12As shown: The locking assembly 42 includes two locking plates 421 and a driving assembly 422; the two locking plates 421 are parallel to each other and located at both ends of the vibration assembly 41, and each end of the locking plate 421 is provided with a plug rod 4211; the driving assembly 422 is disposed between the two locking plates 421 and is used to drive the locking plates 421 to lock the vibration assembly 41.

[0051] Specifically, the drive assembly 422 includes a double-ended lead screw 4221 and a fourth guide rod 4222. The two threaded parts of the double-ended lead screw 4221 are respectively threadedly connected to two locking plates 421. The end of the double-ended lead screw is provided with a rotating handle for rotating the double-ended lead screw. The fourth guide rod 4222 is arranged parallel to one side of the double-ended lead screw 4221 and is used to fix the movement path of the locking plate 421.

[0052] When the paving brick to be cut is placed on the support plate 31, the weight of the paving brick drives the support plate 31 to rotate around the pivot 311. When the support plate 31 rotates to a horizontal state and is coplanar with the plate 32, the compression of the second spring 4134 reaches its maximum, constantly applying a pushing force along the second guide rod 4131 towards the center of the base frame 2 to the second slider 4132. This pushing force is transmitted to the support plate 31 through the third guide rod 4133, the connecting plate 331, and the elastic telescopic rod 332, causing the support plate 31 to tend to rotate upward around the pivot 311, thereby applying an upward pushing force to the paving brick. Therefore, after the paving brick is positioned to be cut, the operator rotates the double-ended lead screw 4221 by turning the handle. The fourth guide rod 4222 restricts the rotation of the locking plate 421, and the two locking plates 421 move synchronously towards the second slider 4132 along the fourth guide rod 4222 under the action of the threaded transmission. The inserts 4211 at both ends of the locking plate 421 engage with the second slider 4132, achieving rigid positioning of the second slider 4132. At this time, the second slider 4132 is fixed and cannot slide under the thrust of the second spring 4134. By positioning the second slider 4132 through the inserts 4211 of the locking assembly 42, the thrust transmission path of the second spring 4134 is completely constrained, offsetting part of the upward rotation thrust of the support plate 31, thereby significantly reducing the upward thrust exerted by the support plate 31 on the road brick during the cutting process.

[0053] Reference Figure 1 and Figure 2 As shown: The dust cover 6 is hinged to the base frame 2 via a hinge. During the cutting operation, it covers the cutting area to achieve a closed shield against dust. The top of the dust cover 6 has a built-in negative pressure dust collection device for collecting dust.

[0054] When placing the paving bricks, the operator flips the two dust covers 6 upwards, rotating them around the hinges to the fully open position. At this point, the cutting area is fully exposed, allowing the operator to place the paving bricks to be cut onto the support surface formed by the support plate 31 and the flat plate 32. During placement, the opening angle of the dust covers 6 is fixed by the damping structure of the hinges, preventing them from falling back and affecting the operation. After the paving bricks are placed, the dust covers 6 rotate around the hinges to the closed position, covering the cutting area directly above, forming a closed cutting space. Dust and flying debris generated during cutting are completely confined inside the dust covers 6. The built-in negative pressure dust extraction device in the dust covers 6 absorbs airborne dust, preventing it from spreading into the working environment, thus suppressing dust dispersion and eliminating the risk of injury from debris.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention. Therefore, the protection scope of this invention should be determined by the appended claims.
