Description

Technical Field

[0001] The invention relates to the technical field of road construction equipment, and in particular to a garden road paving device. Background Art

[0002] In the design and construction of garden roads in some parks, pebbles and concrete are used to pave some uneven roads. When children walk on the uneven roads paved with pebbles, the raised pebbles can stimulate the soles of children's feet, promote the development of their arches, and reduce the development of flat feet.

[0003] During the paving of existing cobblestone roads, the paving device guides the cobblestones to move and fall onto the concrete below through an inclined plate frame. However, in the process of the cobblestones moving along the inclined plate frame, the cobblestones will move at different speeds due to their different sizes. The cobblestones at the back will catch up with the cobblestones in the front, causing the cobblestones to be stacked together. After the cobblestones are stacked, they will overlap up and down. The cobblestones at the bottom are too deep in the concrete and the protrusions are too small to achieve the designed effect. The cobblestones at the top will fall off very easily due to the small contact surface with the concrete, which reduces the quality of the project and requires personnel to manually adjust the stacked cobblestones.

The upper fixed conveyor belt 304 moves with the upper auxiliary frame 3 to adjust the distance between the upper fixed conveyor belt 304 and the second conveyor belt 201.

[0040] In the embodiment of the present disclosure, the lower part of the second lifting screw 301 is screwed to the upper connecting slide column 202, and the second lifting screw 301 is rotatably set on the inner side of one of the side lifting connecting frames 309 on both sides of the inner lifting connecting frame 307.

The thread of the middle connecting screw 404 guides the middle connecting rotating frame 403 to move, and the displacement of the middle connecting rotating frame 403 from the main shaft of the driving motor 401 is enlarged or reduced, and the position of the middle connecting rotating frame 403 is adjusted. The circumferential radius of the rotation of the middle connecting rotating frame 403 is enlarged or reduced, so that the downward pressing height of the flat pressing plate 406 can be adjusted to be higher or lower, and the flat pressing plate 406 is pressed down lower to adapt to the downward pressure on small pebbles.

[0042] Embodiment 2, on the basis of embodiment 1, the unloading funnel 101 and the first laying frame 1 are connected by springs or rubber blocks, and a vibration motor is arranged on the outside of the unloading funnel 101, and the vibration motor drives the unloading funnel 101 to vibrate, thereby promoting the unloading funnel 101 to carry out the operation of discharging pebbles downward, and the number of pebbles from the unloading funnel 101 falling to the first conveyor belt 104 is more stable.

[0043] The working principle of this embodiment is as follows: the unloading funnel 101 contains pebbles, which fall to the top of the first conveyor belt 104, and the first conveyor belt 104 transports the pebbles. When the pebbles on the top of the first conveyor belt 104 pass through the upper blocking baffle 102, only the pebbles smaller than the space between the upper blocking baffle 102 and the first conveyor belt 104 can pass through. The space between the upper blocking baffle 102 and the first conveyor belt 104 is greater than the maximum height of the pebbles. The upper blocking baffle 102 blocks the pebbles stacked on the top of the first conveyor belt 104, and the upper stacked pebbles are blocked by the upper blocking baffle 102. The multi-layer stacked pebbles pass through the upper blocking baffle 102 to become a single layer of pebbles. The pebbles move with the first conveyor belt 104, so as to avoid the stacking of pebbles during transportation, resulting in multiple layers of pebbles on the concrete in the later stage, which leads to the waste of pebbles. It also avoids the situation that after multiple layers of pebbles fall on the concrete, only a small amount of pebbles on the upper layer contact the concrete, which makes them easy to loosen and fall off, eliminating the need for personnel to manually adjust the stacked pebbles. The pebbles on the top of the first conveyor belt 104 are a single layer passing through the bottom space of the upper blocking baffle 102. The first lifting screw 103 rotates, and the thread of the first lifting screw 103 guides the upper blocking baffle 102 to move vertically. The distance between the upper blocking baffle 102 and the first conveyor belt 104 is adjusted and changed to adapt to the stacking and blocking operation of larger or smaller pebbles.

[0044] The first conveyor belt 104 conveys the pebbles to the second conveyor belt 201. The second conveyor belt 201 and the upper fixed conveyor belt 304 are set to rotate in opposite directions. The side lifting connection frame 309 is pulled down by the middle connecting elastic member 306. The side lifting connection frame 309 and the inner lifting connection frame 307 and the middle roller shaft 308 move down synchronously. The middle roller shaft 308 pushes the lower part of the upper fixed conveyor belt 304 to protrude downward. When the upper fixed conveyor belt 304 protrudes, it will pull the conveyor belt driving shafts 303 at both ends to move toward the middle. The upper auxiliary frame 3 and the sub-auxiliary frame 305 move close to each other synchronously to ensure that the upper fixed conveyor belt 304 maintains a tight state. The pebbles on the top of the second conveyor belt 201 are pressed down and fixed, so that the second conveyor belt 201 in the inclined state keeps the position of the top pebbles fixed during the conveying process, so that the pebbles on the top of the second conveyor belt 201 remain in a dispersed state during the paving process, so as to avoid the pebbles rolling along the inclined second conveyor belt 201 and overlapping each other, avoid the pebbles stacking up and down after gathering, and avoid the situation that after multiple layers of pebbles fall on the concrete, only a small amount of pebbles on the upper layer contact the concrete and are easy to loosen and fall off, so as to maintain the beauty of the paving of pebbles, and the pebbles are transported by the second conveyor belt 201 and fall into the concrete below;

[0045] The first laying frame 1, the second laying frame 2, the upper auxiliary frame 3 and the third laying frame 4 move through the wheel hub, and the flat plate 406 moves to the top of the cobblestones with the third laying frame 4, and the driving motor 401 drives the rotating rod 402 to rotate in the circumferential direction, and the rotating rod 402 and the middle connecting rotating frame 403 rotate in the circumferential direction synchronously, and the middle connecting rotating frame 403 drives the upper slide frame 405 and the flat plate 406 to reciprocate vertically synchronously, and the flat plate 406 moves downward to press the cobblestones into the concrete, so as to realize the combination of the cobblestones and the concrete, and complete the paving of the cobblestone road surface, and the middle connecting screw 404 is rotated. , the thread of the middle connecting screw 404 guides the middle connecting rotating frame 403 to move, the displacement of the middle connecting rotating frame 403 from the main shaft of the driving motor 401 is enlarged or reduced, the position of the middle connecting rotating frame 403 is adjusted, and the circumferential radius of the rotation of the middle connecting rotating frame 403 is enlarged or reduced, so that the pressing height of the flat pressing plate 406 is adjusted to be higher or lower, and the flat pressing plate 406 is pressed lower to adapt to the pressing of small pebbles, and the depth of the pebbles pressed into the concrete can be adjusted according to the size of the pebbles, so as to be more compatible with the planning of pebbles of different sizes for different garden roads;

[0046] The second lifting screw 301 of the upper auxiliary frame 3 rotates, and the second lifting screw 301 moves axially synchronously along the upper connecting slide column 202. The second lifting screw 301 and the upper auxiliary frame 3 move synchronously, and the upper fixed conveyor belt 304 moves up and down with the upper auxiliary frame 3. The distance between the upper fixed conveyor belt 304 and the second conveyor belt 201 is adjusted to adapt to the downward pressing and fitting operation of pebbles of different sizes, thereby improving the compatibility with pebbles of different sizes.
