A first rake power roller 22 is provided above the feed port 24, and a second rake power roller 25 is provided at the transverse discharge port. The transverse discharge port is connected in sequence to a guide trough 26 and a sand fixation trough 27. The lower side of the sand fixation trough 27 is located above the seedling port. The sand fixation trough 27 has a first opening that mates with the transverse sand fixation port. A transverse sand fixation telescopic cylinder 29 is fixed above the first opening. The extended end of the transverse sand fixation telescopic cylinder 29 is provided with a transverse pressure head 210 that mates with the first opening and the transverse sand fixation port. A third rake power roller 28 is provided on the feed side of the transverse sand fixation port. A transverse cylinder bracket 211 for mounting the transverse sand fixation telescopic cylinder 29 is provided on the machine body 1. Specifically, the sand-fixing grass is put in from the top of the horizontal feeding box 21, and is transported downward in sequence through the first spike rake power roller 22 and the second spike rake power roller 25. The sand-fixing grass then passes through the guide trough 26 to reach the horizontal sand-fixing mouth of the sand-fixing trough 27. Then the horizontal sand-fixing telescopic cylinder 29 drives the horizontal pressure head 210 to press the sand-fixing grass into the sand to a certain depth, ensuring that the sand-fixing effect is uniform and lasting. The first spike rake power roller 22 and the second spike rake power roller 25 are conventional power rollers.

A longitudinal discharge port is provided on the side of the second opening, and a fourth spike rake power roller 33 is provided on the longitudinal discharge port. A longitudinal cylinder bracket 36 for mounting the longitudinal sand-fixing telescopic cylinder 34 is provided on the machine body 1. Specifically, the fourth spike rake power roller 33 in the longitudinal feeding box 31 outputs the sand-fixing grass from the longitudinal discharge port, and the longitudinal sand-fixing telescopic cylinder 34 presses the sand-fixing grass into the sand through the longitudinal pressure head 35. In another embodiment, a longitudinal partition 32 is provided in the longitudinal feeding box 31, and the longitudinal partition 32 divides the interior of the longitudinal feeding box 31 into two feeding chambers. A longitudinal sand-fixing telescopic cylinder 34 cooperating with the two feeding chambers is provided at the end of the longitudinal discharge port. The two longitudinal sand-fixing telescopic cylinders 34 can simultaneously drive two longitudinal pressure heads 35 to press the sand-fixing grass into the mountain. The longitudinal sand-fixing mechanism 3 cooperates with the transverse sand-fixing mechanism 2 to form a continuous U-shaped sand-fixing grass, which is convenient for forming a complete rectangular sand-fixing grass grid.

[0046] like Figure 9 and 10 As shown, the drilling mechanism 6 is used to open the required holes for seedling planting. After the planting location is determined according to the GPS positioning module, the tree pit is automatically dug. At the same time, the drilling mechanism controls the digging depth according to the type of tree species to ensure that the seedlings can grow steadily. The drilling mechanism 5 includes a drilling lifting block 51, a drill bit 52, a drilling motor and a drilling housing 54. The drilling motor is installed on the drilling lifting block 51, and the drill bit 52 is fixedly connected to the output end of the drilling motor. The drilling housing 54 is provided with a first lifting device for driving the drilling lifting block 51 to rise and fall and a first guide rail 53 that cooperates with the drilling lifting block 51. The first lifting device drives the drilling lifting block 51 to rise and fall, thereby cooperating with the drill bit 52 to drill holes in the ground. The first lifting device can adopt a motor push rod, an electric cylinder or a hydraulic cylinder. Specifically, the first lifting device drives the drilling lifting block 51 to descend, and at the same time, the drilling motor drives the drill bit 52 to rotate to realize the downward drilling operation of the sand. When the required planting is completed, the first lifting device drives the drilling lifting block 51 to return to the initial position to complete the drilling operation.

[0047] The soil-covering and compacting mechanism 6 comprises two soil-covering and compacting claws 61, a soil-covering and lifting block 67, a compacting motor, and a soil-covering and compacting housing 69. Each soil-covering and compacting claw 61 is affixed with a semi-funnel housing 62. The middle portion of each soil-covering and compacting claw 61 is connected to the soil-covering and lifting block 67 via a central connecting rod 63. The rear side of each soil-covering and compacting claw 61 is rotatably connected to a rear swing arm 64. The other end of each rear swing arm 64 is fixedly connected to a driven gear 65. The two driven gears 65 mesh with a driving gear 66, which is fixedly connected to the output end of the compacting motor. The compacting motor and driven gear 65 are both mounted on the soil-covering and lifting block 67. The soil-covering and compacting housing 69 is equipped with a second lifting device that drives the soil-covering and lifting block 67 up and down, and a second guide rail 68 that cooperates with the soil-covering and lifting block 67. The second lifting device is used to drive the soil-covering and lifting block 67 up and down. The second lifting device can be a motor push rod, an electric cylinder, or a hydraulic cylinder. Specifically, the second lifting device drives the soil lifting block 67 to rise and fall, so that the semi-funnel shell 62 is inserted into the bottom two sides of the seedling, and then the compaction motor drives the driven gear 65 to rotate at the same time through the driving gear 66. The two driven gears 65 drive the two soil covering and compacting claws 61 to rotate through the middle connecting rod 63. Under the action of the rear swing arm 64, the two soil covering and compacting claws 61 drive the two semi-funnel shells 62 to close the operation. The closed semi-funnel shells 62 squeeze and compact the sand at the bottom of the seedling, thereby completing the soil covering operation.

[0048] like Figure 11 and 12 As shown, the seedling delivery mechanism 4 includes a seedling delivery tray 41, a seedling delivery wheel 42, a rotating shaft 45 and a seedling delivery motor. The seedling delivery wheel 42 is rotatably mounted on the seedling delivery tray 41 through the rotating shaft 45. The rotating shaft 45 is fixedly connected to the output end of the seedling delivery motor. The top of the seedling delivery tray 41 is provided with a seedling inlet, and the seedling inlet is connected to a seedling delivery bucket 44.

One end of the watering pipe 72 is connected to the water outlet of the water tank 71, and the other end is arranged above the seedling outlet. A water pump and a valve are arranged on the watering mechanism 7, so that the seedlings can be watered after the soil covering and compacting mechanism 6 completes the soil covering operation. After the planting is completed, the water pump is started for watering and irrigation to ensure that the seedlings are thoroughly watered for the first time, thereby ensuring the survival of the seedlings. The watering system uses the Internet of Things smart cloud module to monitor the remaining water in the water tank in real time. When the water volume is insufficient, an alarm signal is issued and the water is returned to the supply station for replenishment. After the seedlings are planted, the regional irrigation system is used to provide the required water for plant growth in the early stage of seedling growth. The water tank can realize the automatic water storage function on rainy days. There is a real-time water volume monitoring system in the water tank. When the remaining water volume is insufficient, an alarm signal is issued and manual replenishment is carried out. At the same time, the built-in sensor of the intelligent irrigation system can be combined with the monitoring of weather and soil moisture to accurately control the amount of irrigation water, which not only ensures the survival rate of seedlings but also saves water resources to the maximum extent. Figure 9 Schematic diagram of the regional irrigation system.

[0050] The machine body 1 is also equipped with a control and monitoring system, comprising a sensor assembly, a central controller, a GPS and Beidou positioning assembly, a Bluetooth and IoT assembly, and an image recognition assembly. The sensor assembly includes soil moisture sensors, terrain sensors, and wind speed sensors, which collect real-time environmental and operational information. The central controller analyzes and processes sensor data, formulates operational strategies, and controls the actions of each actuator. The GPS and Beidou positioning assembly uses the GPS and Beidou positioning module to precisely locate the planting point and transmit the planting location to a cloud platform in real time. The Bluetooth and IoT assembly utilizes the Bluetooth module and the IoT Gizwits Cloud module to transmit information and commands, reporting planting data to the cloud platform in real time. The image recognition assembly utilizes an image recognition camera mounted above the drill head to capture video and upload it to the IoT for analysis of sapling planting progress. The control and monitoring system, combined with mobile devices, enables precise control of seed spacing and depth, improving survival rates. The intelligent navigation system enables autonomous driving and route planning. The machine also features remote monitoring and management capabilities, allowing users to view operational status in real time via a mobile app.
