Description

Technical Field

[0001] The present application relates to the technical field of paving equipment, and more specifically, to cobblestone paving equipment and methods. Background Art

[0002] Wet paving means first laying a layer of cement mortar on the ground where pebbles are to be laid, smoothing it, and then inserting the pebbles into the mortar. Wet paving is mostly used in places such as pebble paths where there is no requirement for the pattern of pebble paving, and can also be used for pebble veneer on the side of the wall.

[0003] The document with prior art publication number CN108999063A provides a device for paving cobblestones for a garden path. The device pours pebbles into a frame so that a first baffle does not contact a discharge pipe, and the pebbles fall onto the path for paving. There is no need for people to manually lay the pebbles on the path, which saves time and effort. The laid pebbles can be compacted by a roller to prevent the pebbles from being kicked off the path when people walk. The amount of pebbles that fall can be controlled by a second baffle.

[0004] However, in the above technical solution, the poured pebbles enter the interior of the discharge pipe along the frame and collide with the discharge pipe, and then fall along the discharge pipe to between the first inclined plate and the second inclined plate, so that the poured pebbles collide violently with each other and with the discharge pipe, the first inclined plate and the second inclined plate, which makes the pebbles easily damaged and affects the effect of the paving of the pebbles.

[0018] By adopting the above technical solution and setting the first spring, after the cam is separated from the adjusting block, the first spring is no longer pulled and starts to reset, thereby pulling the support plate and the limit plate, so that the card strip enters the card slot to position the fixed plate.

[0020] By adopting the above technical solution and setting a deceleration part, the sliding speed of the pebbles can be slowed down, so that the pebbles can move with the movement of the block and the first protective pad until the first protective pad and the block move out of the guide strip.

[0028] Then the pebble contacts the first protective pad, and the first rotating rod drives the rotating plate to rotate. The rotating plate rotates and drives the first sliding rod and the stopper to move downward through the toggle rod, so that the pebble moves slowly downward along with the stopper, reducing the sliding speed of the pebble;

[0030] The rotation of the first rotating rod can drive the second rotating rod and the eccentric wheel to rotate through the cooperation of the transmission wheel and the belt, thereby squeezing the movable plate, causing the movable plate and the second sliding rod to move downward, thereby driving the pressing plate to press down the paved cobblestones to ensure that the height of the paved cobblestones is consistent;

[0031] When the cam is separated from the adjusting block, the first spring causes the limit rod and the support plate to start to reset and move, so that the card strip is inserted into the card slot to position the fixed plate, the rotating shaft and the mounting plate. At the same time, with the cooperation of the rotating plate and the toggle rod, the first slide bar and the stop block can be raised and moved to the initial position, and the eccentric wheel is also separated from the movable plate, so that the second spring can reset and move the movable plate and the second slide bar upward, thereby separating the second protective pad from the pebbles.

[0032] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0033] 1. By setting up a feeding mechanism, individual pebbles can be fed intermittently into each material channel, reducing the collision between pebbles and the collision between pebbles and other objects, thereby preventing the pebbles from being damaged during laying, thereby ensuring the safety of the pebbles after laying.

[0034] 2. By setting up the deceleration part, when paving the pebbles, the pebbles can slide down with the movement of the block and the first protective pad, thereby reducing the sliding speed of the pebbles, preventing the pebbles from splashing on the cement slurry surface, and preventing the pebbles from colliding with the road surface and breaking when the cement slurry is thin.

[0035] 3. By setting the eccentric wheel, the movable plate and the second slide rod, the movable plate can be driven to move downward when the eccentric wheel rotates, so that the movable plate drives the second slide rod and the pressure plate to move downward, so that the second protective pad can press down the pebbles laid on the cement slurry surface, so that the pebbles remain flush and the laying quality of the pebbles is ensured.

[0061] Reference Figure 2 and Figure 3A first protective pad 448 is fixedly connected to the top of the stopper 447. The stopper 447 and the first protective pad 448 are both inclined at a certain angle. When the stopper 447 moves out of the guide bar 413, the pebbles lose the limitation of the guide bar 413 and can slide along the first protective pad 448 into the inside of the feed and discharge trough 5, thereby reducing the sliding speed of the pebbles, and preventing the cement slurry laid on the road surface from being splashed by the pebbles.

[0062] Reference Figure 5 and Figure 7 A storage box 2 is fixedly connected to the inner wall of one side of the fixed box 1 for storing pebbles.

[0063] Reference Figure 2 and Figure 3 A second slide bar 11 is slidably connected to one side of the bottom of the fixed box 1, a movable plate 10 is provided inside the fixed box 1, and the bottom of the movable plate 10 is fixedly connected to the top of the second slide bar 11, the bottom end of the second slide bar 11 is fixedly connected to a pressure plate 12, and the bottom of the pressure plate 12 is fixedly connected to a second spring 13, the second spring 13 is fixedly connected to the inner side of the bottom of the fixed box 1 at one end away from the pressure plate 12, and the second spring 13 is sleeved on the outside of the second slide bar 11, so that when the movable plate 10 moves downward, it can drive the second slide bar 11 and the pressure plate 12 to move downward to press down the laid pebbles, so that they can be stably inserted in the cement slurry.

[0064] The number of the second sliding rods 11 is at least two, so that the movable plate 10 and the pressing plate 12 can move stably.

[0065] Reference Figure 3 and Figure 6 A second protective pad 14 is fixedly connected to the bottom of the pressing plate 12. The second protective pad 14 is made of silica gel and is used to prevent the pebbles from being pressed and damaged.

[0067] Reference Figure 6 The top end surface of the movable plate 10 is an inclined surface, and the bottom end surface thereof is a plane, so that when the eccentric wheel 9 rotates, the movable plate 10 can be fully pressed down to drive the second slide bar 11 to move downward.

[0068] It is worth noting that the method of the cobblestone paving equipment comprises the following steps:

[0069] S1, start the motor 432 through the external controller, and the first rotating rod 433 rotates under the cooperation of the sprocket 434 and the chain 435, so that the cam 436 squeezes the adjustment block 428, so that the clamping bar 424 moves out of the clamping slot 422 to release the positioning of the fixing plate 421;

[0070] S2, at this time, the pebbles are sequentially placed into one group of guide bars 413, so that they follow the guide bars 413 and enter the two protective sleeves 417, so that the mounting plate 415, the rotating shaft 414 and the fixing plate 421 rotate under the action of gravity, so that the pebbles are discharged into the other group of guide bars 413, reducing the collision between the pebbles and preventing the pebbles from being damaged;

[0071] S3, the pebble then contacts the first protective pad 448, and the first rotating rod 433 drives the rotating plate 441 to rotate, and the rotating plate 441 rotates and drives the first sliding rod 446 and the stopper 447 to move downward through the toggle rod 443, so that the pebble moves slowly downward along with the stopper 447, reducing the sliding speed of the pebble;

[0072] S4, when the block 447 moves out of the other set of guide strips 413, the pebbles are affected by the inclined block 447, the first protective pad 448 and gravity, slide down from the first protective pad 448, and fall into the cement slurry along the discharge channel 5, preventing the pebbles from sliding down too fast and causing the cement slurry to splash;

[0073] S5, the rotation of the first rotating rod 433 can drive the second rotating rod 6 and the eccentric wheel 9 to rotate through the cooperation of the transmission wheel 7 and the belt 8, thereby squeezing the movable plate 10, so that the movable plate 10 and the second sliding rod 11 move downward, thereby driving the pressing plate 12 to press down the laid pebbles to ensure that the height of the laid pebbles is consistent;

[0074] S6. When the cam 436 is separated from the adjustment block 428, the first spring 427 causes the limit rod 423 and the support plate 425 to start to reset, thereby inserting the card strip 424 into the card slot 422 to position the fixed plate 421, the rotating shaft 414 and the mounting plate 415. At the same time, with the cooperation of the rotating plate 441 and the toggle rod 443, the first slide bar 446 and the stop block 447 can be moved up to the initial position, and the eccentric wheel 9 is also separated from the movable plate 10, so that the second spring 13 can reset and move the movable plate 10 and the second slide bar 11 up, thereby separating the second protective pad 14 from the pebbles.

[0075] The implementation principle of the cobblestone paving equipment and method of the embodiment of the present application is as follows: when it is necessary to lay cobblestones, the motor 432 is started by an external controller. The start of the motor 432 can drive one of the first rotating rods 433 to rotate, and the cooperation of the sprocket 434 and the chain 435 can make all the first rotating rods 433 rotate. The rotation of the first rotating rod 433 can drive the cam 436 to rotate. When the cam 436 rotates to contact the adjustment block 428, the limit rod 423 rotates with the connecting rod 426 as the axis, so that the card strip 424 moves out of the card slot 422, and the first spring 427 is also pulled by the support plate 425 that moves with the limit rod 423. At this time, the fixed plate 421 is released from the position, and the pebbles can be placed in the guide strip 413 on the top of one side of the connecting plate 3 in turn. At this time, the pebbles fall along the guide strip 413 to between the two protective sleeves 417.

[0076] Since the connecting plate 3 has a certain inclination angle, the pebbles are pressed down, so that the mounting plate 415 is affected by the pebbles and starts to rotate. The rotation of the mounting plate 415 can make the pebbles rotate along with it, thereby dropping the pebbles into the interior of the guide strip 413 at the bottom of one side of the other connecting plate 3, and the pebbles are in contact with the first protective pad 448. When the first rotating rod 433 rotates, it can drive the rotating plate 441 to rotate. The rotation of the rotating plate 441 can make the toggle rod 443 perform a circular motion with the first rotating rod 433 as the axis, thereby driving the mounting frame 444 and the first sliding rod 446 to move downward. The downward movement of the first sliding rod 446 can drive the stopper 447 and the first protective pad 448 to move downward, thereby moving the pebbles downward along with the stopper 447, reducing the sliding speed of the pebbles.

[0077] When the pebbles move out of the guide strip 413, they will slide from the first protective pad 448 into the interior of the discharge chute 5 and be laid on the cement slurry on the road surface, reducing the increase in the speed of the pebbles due to gravity during the falling process, and then reducing the speed of the pebbles when they come into contact with the cement slurry, preventing the cement slurry from splashing.

[0078] At this time, the cam 436 is separated from the adjusting block 428, and the first spring 427 starts to reset and drives the support plate 425 and the limit rod 423 to rotate with the connecting rod 426 as the axis, so that the card strip 424 enters the card slot 422 to position the fixed plate 421, and the toggle rod 443 with the rotation of the rotating plate 441 can drive the mounting frame 444 and the first slide bar 446 to move upward, thereby moving the stopper 447 and the first protective pad 448 to the initial position. At the same time, when the first rotating rod 433 rotates, it can drive the second rotating rod 6 to rotate through the transmission wheel 7 and the belt 8. The rotation of the second rotating rod 6 can drive the eccentric wheel 9 to rotate, thereby squeezing the movable plate 10, so that the movable plate 10 drives the second slide bar 11 to move downward, and the movement of the second slide bar 11 can drive the pressing plate 12 and the second protective pad 14 to move downward, thereby pressing down the paved pebbles, so that the pebbles can fully enter the cement slurry.

2. The cobblestone paving equipment according to claim 1, characterized in that: The drainage part also specifically includes: a protective sleeve fixedly mounted on the outside of the mounting rod, a pad fixedly connected to the outside of the mounting plate to prevent pebbles from colliding with the mounting plate and being damaged when they slide down, and a storage box fixedly connected to the inner wall of one side of the fixed box for storing pebbles.

3. The method for using the cobblestone paving equipment according to claim 2, characterized in that: include: The motor is started by an external controller, and the first rotating rod is rotated under the cooperation of the sprocket and the chain, so that the cam squeezes the adjustment block, so that the card strip moves out of the card slot to release the positioning of the fixed plate; At this time, the pebbles are placed in one group of guide strips in turn, so that they enter between the two protective sleeves along the guide strips, so that the mounting plate, the rotating shaft and the fixing plate rotate under the action of gravity, so that the pebbles are discharged into the lower group of guide strips, reducing the collision between the pebbles and preventing the pebbles from being damaged; Then the pebble contacts the first protective pad, and the first rotating rod drives the rotating plate to rotate. The rotating plate rotates and drives the first sliding rod and the stopper to move downward through the toggle rod, so that the pebble moves slowly downward along with the stopper, reducing the sliding speed of the pebble; When the block moves out from a set of guide strips below, the pebbles are affected by the inclined block, the first protective pad and gravity, slide down from the first protective pad, and fall into the cement slurry along the discharge channel, preventing the pebbles from sliding down too fast and causing the cement slurry to splash; The rotation of the first rotating rod can drive the second rotating rod and the eccentric wheel to rotate through the cooperation of the transmission wheel and the belt, thereby squeezing the movable plate, causing the movable plate and the second sliding rod to move downward, thereby driving the pressing plate to press down the paved cobblestones to ensure that the height of the paved cobblestones is consistent; When the cam is separated from the adjusting block, the first spring causes the limit rod and the support plate to start to reset and move, so that the card strip is inserted into the card slot to position the fixed plate, the rotating shaft and the mounting plate. At the same time, with the cooperation of the rotating plate and the toggle rod, the first slide bar and the stop block can be raised and moved to the initial position, and the eccentric wheel is also separated from the movable plate, so that the second spring can reset and move the movable plate and the second slide bar upward, thereby separating the second protective pad from the pebbles.
