The separating plate 129 is arranged staggered with the material limiting plate 127. The cylinders 1210 are fixedly connected to the upper parts of the front and rear side surfaces outside the loading frame 4. The U-shaped movable plate 128 is fixedly connected between the ends of the telescopic rods of the front and rear cylinders 1210. The U-shaped movable plate 128 is sleeved outside the loading frame 4. The U-shaped movable plate 128 is fixedly connected to the shaft part of the separating plate 129. When the U-shaped movable plate 128 moves, the U-shaped movable plate 128 can drive the separating plate 129 to move up and down for adjustment.

[0033] Initially, the connecting spring 101 is in a stretched state. First, the operator holds the handle 2 to push the mobile platform 1 to the position where the garden trail needs to be paved with pebbles, and makes the loading frame 4 just above the trail paving position, and starts the cylinder 1210. The telescopic rod of the cylinder 1210 is extended and retracted to drive the return-type movable plate 128 to move up and down, and the return-type movable plate 128 moves up and down to drive the partition plate 129 to move up and down. When the partition plate 129 moves up and down to a suitable position for separating the pebbles, the cylinder 1210 is closed. In this way, the amount of separated pebbles can be adjusted, and then an appropriate amount of pebbles are poured into the loading frame 4. The pebbles are in contact with the partition plate 129 and the limiting plate 127. Then the stepping motor 124 is started to drive the disc 125 to rotate, and the rotation of the disc 125 drives the contact rod 126 rotates, the contact rod 126 rotates to drive the straight hole plate 123 to swing back and forth, the straight hole plate 123 swings back and forth to drive the loading frame 4 to swing back and forth, the loading frame 4 swings back and forth to drive the pebbles to swing back and forth through the limiting plate 127, and the pebbles swing back and forth and are evenly distributed in the loading frame 4. In this way, the pebbles can be evenly laid on the concrete, and the partition plate 129 evenly separates the pebbles on the limiting plate 127. The stepping motor 124 is turned off, the contact rod 126 stops driving the straight hole plate 123 to swing back and forth, and the loading frame 4 also stops swinging back and forth, and then the drive motor 12 is started to drive the worm 121 to rotate forward, the worm 121 rotates forward to drive the worm wheel 122 to rotate forward, and the worm wheel 122 rotates forward to drive the limiting plate 127 to swing downward ninety degrees, and the limiting plate 12 7 stops limiting the pebbles, and the pebbles in the loading frame 4 fall down onto the concrete for paving, and then the electric push rod 5 is started, the telescopic rod of the electric push rod 5 extends to drive the return plate 6 to move downward, the return plate 6 moves downward to drive the pressure plate 7 to move downward, the pressure plate 7 moves downward to drive the spur gear 112 to move downward, the spur gear 112 moves downward and is reversed by the rack 111, the spur gear 112 reverses and drives the pressure plate 7 to swing upward by ninety degrees to a horizontal state, the pressure plate 7 swings upward by ninety degrees and contacts with the limiting plate 102 to be limited, at the same time, the pressure plate 7 swings upward to drive the swing rod 8 to swing forward, the swing rod 8 swings forward to drive the driving rod 10 to move forward, the driving rod 10 moves forward to cause the connecting spring 101 to contract and reset, and then the pressure plate 7 continues to swing. The pressing plate 7 and the limit plate 102 cooperate to press the pebbles, so that the pebbles are fully embedded in the concrete and more firmly embedded in the concrete, thereby improving the paving effect. Then, the electric push rod 5 is started again to drive the return plate 6 to move upward and reset. The return plate 6 drives the pressing plate 7 to move upward and reset. The reset of the pressing plate 7 drives the spur gear 112 to mesh with the rack 111. The spur gear 112 rotates forward through the rack 111. The forward rotation of the spur gear 112 drives the pressing plate 7 to swing downward by ninety degrees to reset and disengage from the limit plate 102. The pressing plate 7 swings downward to drive the swing rod 8 to swing backward and reset. The swing rod 8 drives the driving rod 10 to move backward and reset. The connecting spring 101 is stretched, and the electric push rod 5 is closed.Then start the driving motor 12 to reverse, driving the worm 121 to reverse. The reverse rotation of the worm 121 drives the worm wheel 122 to reverse, and the reverse rotation of the worm wheel 122 drives the material limiting plate 127 to swing upward by ninety degrees to reset. The reset of the material limiting plate 127 continues to enclose the inside of the loading frame 4. Then pull the handle 2 to drive the moving platform 1 to move to the right. The moving platform 1 drives the loading frame 4 to move to the right through the mounting frame 3. When the loading frame 4 is exactly corresponding to the next paving position on the footpath, stop pulling the handle 2, and then pour an appropriate amount of pebbles into the loading frame 4. By following the above operations, the pebbles can be evenly and warmly paved onto the concrete again. When the pebbles are paved on the footpath, stop pulling this device.

[0034] Please refer to Figure 8As shown, the pebble paving device for garden landscaping also includes a feeding component installed on the mobile platform 1. The feeding component includes a loading hopper 13, an inclined frame 131, a fixed screening frame 132, a guiding frame 133, a collecting frame 134, a receiving frame 1341 and a pushing component. In the middle of the outer left side of the mounting frame 3, a guiding frame 133 is fixedly connected. On the left side of the top of the mobile platform 1, a collecting frame 134 is placed. The collecting frame 134 is located directly below the guiding frame 133. The collecting frame 134 can collect large pebbles. In the middle of the top of the mounting frame 3, a fixed screening frame 132 is fixedly connected. The fixed screening frame 132 is inclined. The fixed screening frame 132 corresponds to the feeding end of the loading frame 4 and the feeding end of the guiding frame 133. On the right side of the top of the mobile platform 1, a loading hopper 13 is fixedly connected. The discharging end of the loading hopper 13 is fixedly connected with an inclined frame 131. The bottom of the inclined frame 131 is open. The left side of the inclined frame 131 is fixedly connected with the right side of the fixed screening frame 132. On the right side of the top of the mobile platform 1, a receiving frame 1341 is placed. The receiving frame 1341 is located below the inclined frame 131. The receiving frame 1341 can collect the screened fine pebbles. A pushing component is arranged on the inclined frame 131. When the pushing component operates, the pushing component can drive the pebbles to move leftward for conveying. The pushing component includes a rotating shaft 135, a belt component 136, a pushing plate 137, a screening plate 138 and a servo motor 139. Between the upper parts of the front and rear sides inside the inclined frame 131, a screening plate 138 is fixedly connected. When the pebbles fall from the loading hopper 13, the screening plate 138 can preliminarily screen the pebbles. The rotating shaft 135 is rotatably connected symmetrically left and right between the front and rear sides of the inclined frame 131. The rotating shaft 135 is located on both sides of the screening plate 138. Between the left and right rotating shafts 135, a belt component 136 is symmetrically connected front and rear. The belt component 136 is composed of two belt pulleys and a flat belt. Among them, the two belt pulleys are respectively fixedly sleeved on the left and right rotating shafts 135. The flat belt is wound between the two belt pulleys. Between the front and rear belt components 136, pushing plates 137 are fixedly connected at equal intervals in the circumferential direction. When the pushing plate 137 rotates reversely, the pushing plate 137 can push the screened pebbles leftward into the fixed screening frame 132. On the right side of the front outer surface of the inclined frame 131, a servo motor 139 is installed. The output shaft of the servo motor 139 is fixedly connected with the front end of the right rotating shaft 135.

[0035] When the device moves to the position on the footpath where pebbles need to be paved, an appropriate amount of pebbles is poured into the loading hopper 13. The pebbles in the loading hopper 13 fall into the inclined frame 131 and contact the screening plate 138. Start the reverse rotation of the servo motor 139 to drive the reverse rotation of the right rotating shaft 135. The reverse rotation of the right rotating shaft 135 drives the reverse rotation of the belt assembly 136 through the left rotating shaft 135. The reverse rotation of the belt assembly 136 drives the reverse rotation of the pushing plate 137. The reverse rotation of the pushing plate 137 drives the pebbles to move leftward for conveying. During the conveying process, the screening plate 138 screens the pebbles. The small pebbles pass through the screening plate 138 and fall into the receiving frame 1341. The pebbles larger than the sieve holes of the screening plate 138 are continuously pushed by the pushing plate 137 to move leftward for conveying. When the pebbles moving leftward are separated from the screening plate 138, the pebbles fall into the fixed screening frame 132. The fixed screening frame 132 completes the final screening of the pebbles. The pebbles of the required size pass through the fixed screening frame 132 and fall into the loading frame 4 for use. The unqualified pebbles slide down from the fixed screening frame 132 into the guiding frame 133. The pebbles in the guiding frame 133 fall into the collecting frame 134 for collection. When all the pebbles in the loading hopper 13 are screened and conveyed, turn off the servo motor 139, and the rotating shaft 135 stops driving the reverse rotation of the pushing plate 137 through the belt assembly 136, then the paving of the pebbles can be started. When the collecting frame 134 and the receiving frame 1341 are filled with an appropriate amount of unqualified pebbles, pick up the collecting frame 134 and the receiving frame 1341 to perform subsequent processing on the unqualified pebbles. After all the unqualified pebbles are poured out, put the collecting frame 134 and the receiving frame 1341 back on the moving platform 1. In this way, it can prevent unqualified pebbles from being embedded in the concrete during paving and affecting the use of the footpath, thus ensuring the normal use of the footpath.

[0036] Please refer to Figure 9 As shown, the pebble paving device for garden landscaping also includes a guiding pipe 14, an atomizing nozzle 15 and a water supply tank 16. The left side of the bottom of the moving platform 1 is fixedly connected with the guiding pipe 14. The guiding pipe 14 corresponds to the open part of the moving platform 1. The atomizing nozzles 15 are evenly spaced and connected to the left and right sides of the guiding pipe 14. The atomizing nozzles 15 can atomize water and spray it on the concrete. The water supply tank 16 is installed on the top right front side of the moving platform 1. The water outlet end of the water supply tank 16 is connected to the water inlet end of the guiding pipe 14.

[0037] Initially, the water supply tank 16 is filled with an appropriate amount of water. When the pebbles are embedded in the concrete and the paving is completed, start the water supply tank 16 to drain the water into the guiding pipe 14. The water in the guiding pipe 14 is sprayed out through the atomizing nozzles 15. The atomized water is sprayed on the concrete, making the concrete more moist, enabling the concrete to contact the pebbles more closely, and then turn off the water supply tank 16, and the atomizing nozzles 15 stop spraying water. In this way, the pebbles can be paved more firmly on the concrete, thus further improving the firmness effect.
