Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1 - Figure 4 As shown in the embodiment of this application, a sidewalk paving machine is proposed, including a vehicle body 1. The front end to the rear end of the vehicle body 1 are sequentially and alternately provided with a leveling device 3, a mortar spreading device, a stone slab paving device and a vibration compaction device 9. When the vehicle body 1 moves in the forward direction, the leveling device 3 smooths the base surface and the mortar spreading device pours a mortar layer of a preset thickness on the base surface. The stone slab paving device lays the floor layer by layer on the top of the mortar layer, and the vibration compaction device 9 vibrates and compacts the floor layer sequentially.

[0024] First of all, it should be stated that by integrating the sweeping device 3, the slurry spreading device, the stone slab paving device and the vibration compaction device 9 into the vehicle body 1, the efficiency and accuracy of the installation of sidewalk stone materials are effectively improved, the number of manual operation steps is reduced, the construction period is effectively shortened, the labor consumption is greatly reduced, and the construction cost is saved.

[0025] The aforementioned leveling device 3 includes a first drive structure located at the bottom of the vehicle body 1. The first drive structure is equipped with leveling rollers, which are arranged parallel to the paving base surface. In other words, the leveling rollers level the soil layer on the paving base surface by rotating, ensuring the flatness of the subsequent pouring layer and improving the overall paving quality. The leveling rollers can be existing leveling and compaction rollers or sweeping rollers.

[0026] The aforementioned grouting device includes a mortar mixing tank 4 installed on the vehicle body 1. A grouting mechanism 5 is connected to the lower part of the mortar mixing tank 4. The grouting mechanism 5 is used to spread mortar evenly on the base surface. The mortar mixing tank 4 includes a tank body, and a mixing paddle is installed inside the tank. Under continuous operation of the mixing paddle, the prepared mortar in the mortar mixing tank 4 is guaranteed not to solidify or experience a decrease in flowability. Furthermore, a connecting pipe is provided between the mortar mixing tank 4 and the grouting mechanism 5, and a control valve is installed on the pipe. This valve can be electrically operated, and the grouting operation is initiated by controlling the valve's opening and closing.

[0027] The grouting mechanism 5 includes a grouting groove connected to the mortar mixing tank 4. The grouting groove has a grouting port 63 parallel to the paving base surface, and an adjustment structure for adjusting the opening height of the grouting port 63. The length of the grouting groove is adapted to the size of the slab bricks. Mortar flows evenly from the mortar mixing tank 4 into the grouting groove, and then spreads evenly from the grouting port 63 onto the paving base surface. In this embodiment, the opening of the grouting port 63 is rectangular, with its long base parallel to the paving base surface. Variations in the width of the grouting port 63 allow for changes in the mortar flow rate per unit time, thereby adjusting the thickness of the grouting layer by changing the width of the grouting hole, ensuring the accuracy and quality of subsequent paving processes.

[0028] The aforementioned adjustment structure includes a base plate 61 rotatably mounted on the grouting groove. An adjustment bolt structure 62 is provided between the base plate 61 and the grouting groove. By adjusting the adjustment bolt structure 62, the opening height of the grouting port 63 can be changed. The grouting hole width can be changed by adjusting the angle of the base plate 61 through the adjustment mechanism 6, thereby enabling precise adjustment of the grouting layer thickness.

[0029] The aforementioned paving device includes a paving stone bin 7 disposed on the vehicle body 1. The lower end of the paving stone bin 7 is provided with a dropping opening 81. A dropping structure 8 is provided at the dropping opening 81. The dropping structure 8 is used to control the paving stones to fall sequentially. In some embodiments, an automatic blocking structure is provided at the dropping opening 81. The automatic blocking structure regularly realizes the blocking and opening functions. Specifically, it can be achieved by a crank-slider mechanism driving the baffle. The automatic blocking mechanism can ensure that the paving stones fall regularly, stably and accurately to the preset position on the surface of the grouting layer. To further reduce costs and decrease the footprint and weight of the equipment, multiple partitions 71 are spaced apart inside the slab storage 7. These partitions 71 are parallel to the paving base surface, and they divide the space inside the slab storage 7 into multiple storage gaps. Each storage gap contains a slab. The partitions 71 are detachably mounted on the slab storage 7. The dropping structure 8 includes a drawer 82 located at the dropping opening 81. The drawer 82 is slidably mounted on the slab storage 7 and is located below the lowest partition 71. In use, the slab to be paved is dropped onto the upper surface of the drawer 82 through the lowest partition 71. When the vehicle 1 moves to a designated position, the drawer 82 is pulled out to drop the slab onto the designated position of the mortar layer. This process is repeated as the vehicle 1 moves to different positions to achieve the paving effect.

[0030] The aforementioned vibration flattening device 9 includes a vibration motor installed on the vehicle body 1. The vibration motor is equipped with a hammer, which is used to swing and strike the upper surface of the paved stone slab. Through vibration flattening, the paved stone slab is made flatter, and there are no gaps between the stone slab and the mortar layer.

[0031] Furthermore, in order to adapt to the paving requirements of slab bricks of different thicknesses, a moving wheel assembly 2 is provided at the lower end of the vehicle body 1. A height adjustment component is provided between the moving wheel assembly 2 and the vehicle body 1. By adjusting the height adjustment component, the distance between the vehicle body 1 and the paving base can be changed, thereby adapting to the paving plan of slab bricks of different thicknesses.

[0032] In summary, this utility model proposes a sidewalk paving machine. This device is simple and flexible to operate, with seamless construction procedures, effectively improving the efficiency and accuracy of sidewalk stone installation, significantly shortening the construction period, further reducing labor consumption, and saving construction costs. Moreover, the overall structure does not generate waste gas or waste materials during operation, minimizing environmental pollution.
