Description

Technical Field

[0001] This invention relates to the field of forest replanting technology, and in particular to a device for promoting the rapid survival of seedlings replanted in forests. Background Technology

[0002] To increase forest coverage, protect the ecological environment, and prevent wind erosion and sand fixation, we must start with afforestation. Mechanization can accelerate afforestation, but during mechanized afforestation, some seedlings may die due to quality issues or planting techniques, so replanting is necessary.

[0003] Understory replanting is an important forest management method that can improve forest productivity, enhance the forest environment, and ensure the healthy development of forest ecosystems. Understory replanting is generally carried out by planting seedlings; however, seedlings are easily affected by the environment after planting, leading to low survival rates and even death. To improve seedling survival rates and the effectiveness of understory replanting, it is necessary to develop a device that can promote rapid seedling survival. Summary of the Invention

[0004] The purpose of this invention is to provide a device that promotes the rapid survival of seedlings replanted under forest canopies, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for promoting the rapid survival of seedlings replanted under forest canopies, comprising a trolley, wherein a replanting hole is provided through the surface of the trolley, an inner nesting cylinder is slidably inserted into the inner wall of the replanting hole, an arc-shaped shovel is fixedly installed at the bottom of the inner nesting cylinder, a turntable is provided inside the inner nesting cylinder, a rotating shaft is fixedly installed at the top of the turntable, the output shaft of a second motor is fixedly installed at the end of the rotating shaft away from the turntable, the second motor is fixedly installed on the surface of a moving plate, and a lifting assembly is provided at the end of the moving plate for moving the inner nesting cylinder up and down.

[0006] Preferably, the lifting assembly includes a support frame one and a support frame two. The support frame one and the support frame two are symmetrically fixedly installed on the top of the trolley. Both the support frame one and the support frame two have recessed grooves on their surfaces. A limit rod is fixedly installed inside the groove of the support frame one. A lead screw is rotatably installed through the groove of the support frame two. The output shaft of the motor one is fixedly installed on the top of the lead screw. The motor one is fixedly installed on the top of the support frame two. One end of the moving plate is threadedly connected to the surface of the lead screw, and the end of the moving plate away from the lead screw is slidably sleeved on the surface of the limit rod.

[0007] Preferably, a fixing sleeve is fixedly installed on the surface of the rotating shaft, and a limiting head is symmetrically fixedly installed on the surface of the fixing sleeve. An arc-shaped connecting block one and an arc-shaped connecting block two are symmetrically fixedly installed on the top of the inner nested cylinder. Limiting slots are symmetrically installed at both ends of the arc-shaped connecting block one and the arc-shaped connecting block two. The two ends of the limiting head are staggered and engaged with the inner walls of the limiting slots of the arc-shaped connecting block one and the arc-shaped connecting block two. A mud scraper is symmetrically opened on the surface of the turntable with the rotating shaft as the center. The turntable is slidably sleeved on the inner wall of the inner nested cylinder.

[0008] Preferably, a seedling support rod is hinged to the top of the first arc-shaped connecting block, and a seedling support sleeve is fixedly installed at the end of the first seedling support rod away from the first arc-shaped connecting block. A buffer pad is fixedly connected to the inner wall of the first seedling support sleeve, and a slot is provided at the end of the first seedling support sleeve. A seedling support rod is hinged to the top of the second arc-shaped connecting block, and a seedling support sleeve is fixedly installed at the end of the second seedling support rod away from the second arc-shaped connecting block. A buffer pad is fixedly connected to the inner wall of the second seedling support sleeve, and a locking head is provided at the end of the second seedling support sleeve. The locking head and the slot are engaged together.

[0009] Preferably, the bottom of the trolley is bolted with casters, and the top of the trolley is fixedly mounted with a push handle, the surface of which is provided with a switch button for controlling motor one and motor two.

[0010] Preferably, the bottom of the turntable is level with the bottom of the arc-shaped blade.

[0011] Compared with related technologies, the device for promoting the rapid survival of seedlings replanted in forests provided by this invention has the following advantages:

[0012] Beneficial effects:

[0013] 1. The pusher moves the trolley to the replanting area via the casters. The inner nesting cylinder is then placed on the ground through the replanting hole. Motor 1 is started, causing its output shaft to rotate the lead screw. The limiting rod limits the movement of the moving plate, which in turn moves the turntable vertically downwards. When the bottom of the limiting clamp contacts the top surface of the inner nesting cylinder, Motor 2 is started, causing its output shaft to rotate. This rotates both ends of the limiting clamp until they engage with the inner wall of the limiting groove, causing the inner nesting cylinder to rotate. Then, the curved shovel and the mud scraper dig holes in the replanting area, and the top surface of the turntable collects the soil. This eliminates the need for manual digging when replanting seedlings, effectively improving planting efficiency and reducing labor intensity. The depth of the hole can be adjusted according to the number of rotations of the lead screw to accommodate different types of seedlings, effectively improving the adaptability of the device.

[0014] 2. After digging the hole, rotate the shaft to disengage the limit clamp from the inner wall of the limit clamp slot. Start the motor and reverse it to move the moving plate vertically upward, bringing the turntable and the soil generated during digging out of the inner nested cylinder. The inner nested cylinder is left in the hole, forming a barrier. As the turntable moves vertically downward, it flattens the soil at the bottom of the hole. This effectively reduces water loss when watering the hole, ensuring sufficient moisture in the area near the seedlings and improving the survival rate of the seedlings. After the seedlings survive, the inner nested cylinder can be directly removed and recycled, making it more convenient to use and effectively improving the practicality of the device.

[0015] 3. After the seedlings are planted inside the inner nesting tube and the soil is filled, pry open the seedling support rod one and the seedling support rod two, so that the buffer pad one and the buffer pad two can compress the seedlings. The seedling support sleeve one and the seedling support sleeve two are merged by the snapping of the slot one and the snapping head one, so that the seedlings can receive good support in the early stage of planting, effectively avoiding the phenomenon of seedlings tipping over due to strong winds or other environmental factors, and further improving the survival rate of seedlings.

[0023] Example 1:

[0024] Please see Figures 1-5 This invention provides a technical solution, including a trolley 1, characterized in that: a replanting hole 12 is provided through the surface of the trolley 1, an inner nesting cylinder 22 is slidably inserted into the inner wall of the replanting hole 12, an arc-shaped shovel 23 is fixedly installed at the bottom of the inner nesting cylinder 22, a turntable 24 is provided inside the inner nesting cylinder 22, a rotating shaft 21 is fixedly installed at the top of the turntable 24, the output shaft of a second motor 2 is fixedly installed at the end of the rotating shaft 21 away from the turntable 24, the second motor 2 is fixedly installed on the surface of a moving plate 19, and the end of the moving plate 19 is provided with... A lifting assembly is provided for the vertical movement of the inner nested cylinder 22. The lifting assembly includes a first support frame 13 and a second support frame 15. The first support frame 13 and the second support frame 15 are symmetrically fixedly installed on the top of the trolley 1. Both the first support frame 13 and the second support frame 15 have recessed grooves on their surfaces. A limit rod 18 is fixedly installed inside the groove of the first support frame 13. A lead screw 16 is rotatably installed through the groove of the second support frame 15. The output shaft of the first motor 17 is fixedly installed on the top of the lead screw 16. The first motor 17 is fixedly installed on... At the top of support frame 2 15, one end of the movable plate 19 is threadedly connected to the surface of the lead screw 16, and the other end of the movable plate 19, away from the lead screw 16, is slidably sleeved onto the surface of the limit rod 18. A fixing sleeve 26 is fixedly installed on the surface of the rotating shaft 21, and limit clamps 27 are symmetrically fixedly installed on the surface of the fixing sleeve 26. Arc-shaped connecting block 1 28 and arc-shaped connecting block 2 34 are symmetrically fixedly installed on the top of the inner nested cylinder 22. Limit clamps 35 are symmetrically installed at both ends of arc-shaped connecting block 1 28 and arc-shaped connecting block 2 34. The two ends of the limiting clamp head 27 are staggered and engaged with the inner wall of the limiting clamp groove 35 of the arc-shaped connecting block 1 28 and the arc-shaped connecting block 2 34. The surface of the turntable 24 is symmetrically provided with a mud scraper 25 with the rotating shaft 21 as the center. The turntable 24 is slidably sleeved on the inner wall of the inner nesting cylinder 22. The bottom of the trolley 1 is bolted with a universal wheel 11. The top of the trolley 1 is fixedly installed with a pusher 14. The surface of the pusher 14 is provided with a switch button for controlling the motor 1 17 and the motor 2 2. The bottom of the turntable 24 is kept horizontal with the bottom of the arc-shaped scraper 23.

[0025] In this embodiment: the pusher 14 moves the trolley 1 to the replanting area via the casters 11. The inner nesting cylinder 22 is then placed on the ground through the replanting hole 12. Motor 17 is started, causing its output shaft to rotate the lead screw 16. The limiting rod 18 causes the moving plate 19 to move vertically, which in turn causes the turntable 24 to move vertically downwards. When the bottom of the limiting clamp 27 contacts the top surface of the inner nesting cylinder 22, motor 2 is started, causing its output shaft to rotate the shaft 21. This causes both ends of the limiting clamp 27 to rotate to the inner wall of the limiting groove 35, completing the engagement with the limiting groove 35. This causes the inner nesting cylinder 22 to rotate. Then, the arc-shaped shovel 23 and the mud scraper 25 dig holes in the replanting area, and the top surface of the turntable 24 collects the soil. This eliminates the need for manual digging when replanting seedlings, effectively improving the planting efficiency. This device improves planting efficiency and reduces labor intensity. The depth of the pit can be adjusted according to the number of rotations of the lead screw 16 to accommodate different types of seedlings, effectively enhancing its adaptability. After digging, rotating the shaft 21 causes the limit clamp 27 to disengage from the inner wall of the limit clamp groove 35, and starting the motor 17 to reverse, thereby moving the moving plate 19 vertically upwards. This carries the turntable 24 and the soil generated during digging out of the inner nesting cylinder 22, leaving the inner nesting cylinder 22 inside the pit to form a barrier. The turntable 24 also flattens the soil at the bottom of the pit during its vertical downward movement, effectively reducing water loss during irrigation and ensuring sufficient moisture in the area near the seedlings, thus improving seedling survival rate. Furthermore, after the seedlings survive, the inner nesting cylinder 22 can be directly removed and recycled, making it more convenient to use and effectively improving the device's practicality.

[0026] Example 2:

[0027] Please see 5- Figure 6 Based on Embodiment 1, the present invention provides a technical solution: A seedling support rod 29 is hinged to the top of the arc-shaped connecting block 28. A seedling support sleeve 3 is fixedly installed at the end of the seedling support rod 29 away from the arc-shaped connecting block 28. A buffer pad 32 is fixedly connected to the inner wall of the seedling support sleeve 3. A slot 33 is provided at the end of the seedling support sleeve 3. A seedling support rod 36 is hinged to the top of the arc-shaped connecting block 34. A seedling support sleeve 37 is fixedly installed at the end of the seedling support rod 36 away from the arc-shaped connecting block 34. A buffer pad 38 is fixedly connected to the inner wall of the seedling support sleeve 37. A locking head 39 is provided at the end of the seedling support sleeve 37. The locking head 39 is engaged with the slot 33.

[0028] In this embodiment: after the seedlings are planted inside the inner nesting cylinder 22 and the soil is filled, the seedling support rod 29 and the seedling support rod 36 are bent to compress the seedlings with the buffer pads 32 and 38. The seedling support sleeve 3 and the seedling support sleeve 37 are merged by the snapping of the slot 33 and the snapping head 39. This allows the seedlings to receive good support in the early stage of planting, effectively preventing the seedlings from tipping over due to strong winds or other environmental factors, and further improving the survival rate of the seedlings.

[0029] Working principle: Pusher 14 moves trolley 1 to the replanting area via casters 11. Inner nested cylinder 22 is then placed on the ground through replanting hole 12. Motor 17 is started, causing its output shaft to drive screw 16 to rotate. Limiting action by limit rod 18 causes moving plate 19 to move vertically, which in turn drives turntable 24 to move vertically downward. When the bottom of limit clamp 27 contacts the top surface of inner nested cylinder 22, motor 2 is started, causing its output shaft to drive rotating shaft 21 to rotate, which in turn drives both ends of limit clamp 27 to rotate into limit clamp slots. The inner wall of the device 35 engages with the limiting slot 35, causing the inner nested cylinder 22 to rotate. Then, the arc-shaped shovel 23 and the mud scraper 25 dig holes in the replanting area, and the top surface of the turntable 24 collects the soil. This eliminates the need for manual digging when replanting seedlings, effectively improving planting efficiency and reducing labor intensity. The depth of the hole can be adjusted according to the number of rotations of the lead screw 16 to accommodate different types of seedlings, effectively improving the device's adaptability. After digging, rotating the shaft 21 causes the limiting head 27 to disengage. When the motor 17 reverses, it moves the moving plate 19 vertically upwards, causing the turntable 24 and the soil generated during digging to be carried out of the inner nesting cylinder 22. The inner nesting cylinder 22 remains inside the pit, forming a barrier. The turntable 24 also flattens the soil at the bottom of the pit during its vertical downward movement. This effectively reduces water loss when watering the pit, ensuring sufficient moisture in the area near the seedlings and significantly improving their survival rate. Furthermore, once the seedlings have survived, the inner nesting cylinder 22 can be directly removed and recycled. It is more convenient to use and effectively improves the practicality of the device. After the seedlings are planted inside the inner nesting cylinder 22 and the soil is filled, the seedling support rod 1 29 and seedling support rod 2 36 are bent so that the buffer pad 1 32 and buffer pad 2 38 squeeze the seedlings. The seedling support sleeve 1 3 and seedling support sleeve 2 37 are merged by the snapping of the slot 1 33 and the snapping head 1 39. This allows the seedlings to receive good support in the early stage of planting, effectively avoiding the phenomenon of seedlings falling over due to strong winds or other environmental factors, and further improving the survival rate of seedlings.
