Description

Technical Field

[0001] This invention relates to the field of forest seedling transplanting technology, specifically a protective device for forest seedling transplanting. Background Technology

[0002] Seedlings refer to saplings that are less than 1.5 meters tall and have a trunk diameter of less than 2.5 centimeters. Seedlings are usually 1-2 years old, have a distinct stem, and their crown shape is not yet complete. They usually need to be pruned. Seedlings are generally transplanted from nurseries and have not yet undergone large-scale cultivation and processing, maintaining their natural growth state. Currently, after workers remove the saplings, they place them directly inside the truck bed. The saplings are piled up inside the truck bed for transplanting and transportation. However, during the vehicle's movement, the saplings are prone to contact and collisions inside the truck bed due to the vehicle's shaking, which can cause damage or breakage to the surface of the saplings and affect their transplant survival rate.

A limit hole 22 is provided on the surface of the support plate 13. A pressure plate 11 is fixedly connected to the surface of the sponge board 14 and the bearing plate 13. When the tree seedling 4 is placed inside the cylindrical frame 15, the bearing plate 13 contacts the surface of the tree seedling 4 through the sponge board 14. The bearing plate 13 supports the branches of the tree seedling 4, preventing the branches from breaking due to gravity when the cylindrical frame 15 is tilted. After the tree seedling 4 is placed, the electric push rod 16 is activated to pull the center of the tripod 17 upward. When the tripod 17 moves, its end will pull the rotating rod 12 to reset through the positioning plate 18. After the cylindrical frame 15 is reset, the tree seedling 4 will remain straight, preventing the branches of the tree seedling 4 from breaking due to the weight of the branches during transplanting.

[0024] There are two sliding hole plates 2, which are symmetrically arranged with the center plate 1 as the center. The bottom of the sliding hole plate 2 is fixedly connected to the top of the bottom plate 3. There are two rotating rods 12, which are symmetrically arranged with the center plate 1 as the center. There are multiple bearing plates 13, which are arranged in two groups, and the number of bearing plates 13 in each group is the same. The top of the bearing plates 13 extends to the outer end of the top of the center plate 1.

[0025] The end of the cylindrical frame 15 away from the bearing plate 13 is spaced apart from the surface of the center plate 1. There are two tripods 17, which are symmetrically arranged with the rotating rod 12 as the center. The center of the tripod 17 is hinged. The end of the tripod 17 extends to the outer end of the sliding hole plate 2. The position of the inclined pressure plate 21 corresponds to the limiting hole 22.

[0026] The top of the inclined pressure plate 21 contacts the bottom of the lifting plate 23. The surface of the lifting plate 23 is slidably connected to the inner wall of the slide groove 24. The end of the curved plate 19 away from the lifting plate 23 passes through the cylindrical frame 15 and extends to the outer end of the cylindrical frame 15. The end of the top plate 20 away from the cylindrical frame 15 is inclined downward. A soil pot 5 is provided inside the cylindrical frame 15, and the soil pot 5 contains tree seedlings 4.

[0027] The extrusion component 7 includes a spring sheet 30. The end of the spring sheet 30 is fixedly connected to the lower surface of the cylindrical frame 15. The end of the spring sheet 30 away from the cylindrical frame 15 is fixedly connected to the surface of the inclined plate 35. A right-angle plate 34 is fixedly connected to the surface of the inclined plate 35. The end of the support plate 33 away from the inclined plate 35 is fixedly connected to the top of the cylindrical frame 15. When the lifting plate 23 moves upward, it pushes the top plate 20 upward via the bent plate 19. During this movement, the top plate 20 contacts the bottom of the inclined plate 35 and pushes the inclined plate 35 against the support plate. When the end of 33 rotates, the inclined plate 35 pushes the squeezing plate 31 toward the surface of the seedling 4. When the squeezing plate 31 moves, it squeezes the seedling 4 through the sponge pad 32, which improves the stability of the seedling 4 during transplanting and transportation and avoids the seedling 4 from being bumped due to shaking. At the same time, the bottom of the right-angle plate 34 will contact the top of the potting soil 5. The right-angle plate 34 is used to press the potting soil 5 into the inside of the cylindrical frame 15, which further improves the stability of the seedling 4 during transplanting and transportation.

[0028] The extrusion plate 31 is located above the cylindrical frame 15. The end of the sponge pad 32 away from the extrusion plate 31 is in contact with the surface of the tree seedling 4. The end of the right-angle plate 34 away from the inclined plate 35 is in contact with the top of the potting soil 5. The top of the top plate 20 is in contact with the bottom of the support plate 33. The lower surface of the top plate 20 is in contact with the bottom of the inclined plate 35.

[0029] The clamping component 8 includes a movable triangular plate 43, the end of which is sleeved on the surface of a rectangular frame 41. A through hole 44 is formed on the surface of the center plate 1. A triangular push plate 45 is slidably connected to the bottom of the inner wall of the through hole 44. A spring rod 46 is fixedly connected to the inner wall of the center plate 1, with one end of the spring rod 46 away from the center plate 1 fixedly connected to the end of the triangular push plate 45. A force-bearing plate 47 is hinged to the surface of the center plate 1. When the spring rod 46 moves, it pushes the triangular push plate 45 to slide into the through hole 44. When moving, it will contact the center of the movable triangle 43 and push its center upward. When moving, the end of the movable triangle 43 will push the rectangular frame 41 towards the surface of the tree seedling 4. When moving, the rectangular frame 41 will squeeze the tree seedling 4 through the rectangular sponge pad 42. The rectangular frame 41 will squeeze and limit the branches of the tree seedling 4, improving the stability of the tree seedling 4 during transplanting and transportation. The bearing plate 13 and the rectangular frame 41 cooperate with each other to prevent the tree seedling 4 from shaking violently during transplanting and transportation.

[0030] The center of the movable triangle 43 is hinged, and the center of the movable triangle 43 is located inside the through hole 44. The bottom center of the movable triangle 43 contacts the top of the triangle push plate 45.

[0031] The telescopic end of the elastic rod 46 extends to the outer end of the center plate 1, the lower surface of the force plate 47 contacts the telescopic end of the elastic rod 46, and the end of the pressure plate 11 away from the bearing plate 13 contacts the surface of the force plate 47.

[0032] In use, after placing the base plate 3 inside the truck bed, the electric actuator 16 is activated to extend downwards. The electric actuator 16 pushes the center of the tripod 17 downwards, causing the end of the tripod 17 to expand towards the outer end of the sliding plate 2. As the tripod 17 expands, it pushes the rotating rod 12 to rotate via the positioning plate 18. The rotating rod 12, in turn, drives the cylindrical frame 15 to rotate via the bearing plate 13, adjusting the angle of the cylindrical frame 15 so that workers can place the saplings 4 inside for transplanting. When the top of the cylindrical frame 15 is tilted, workers can more easily place the saplings 4 inside. The support plate 13 contacts the surface of the tree seedling 4 through the sponge board 14. The support plate 13 supports the branches of the tree seedling 4, preventing the branches from breaking due to gravity when the cylindrical frame 15 is tilted. After the tree seedling 4 is placed, the electric push rod 16 is activated to pull the center of the tripod 17 upward. When the tripod 17 moves, its end will pull the rotating rod 12 to reset through the positioning plate 18. After the cylindrical frame 15 is reset, the tree seedling 4 will remain straight, preventing the branches of the tree seedling 4 from breaking due to the weight of the branches during transplanting. The angle of the cylindrical frame 15 can be adjusted by using the tripod 17, which makes it convenient for workers to load and unload the tree seedling 4, improving convenience. When the cylindrical frame 15 is reset, the inclined pressure plate 21 enters the interior of the cylindrical frame 15 through the limiting hole 22 and contacts the bottom of the lifting plate 23. As the angle of the cylindrical frame 15 changes, the inclined pressure plate 21 pushes the lifting plate 23 upward. When the lifting plate 23 moves upward, it pushes the top plate 20 upward through the bending plate 19. When the top plate 20 moves, it contacts the bottom of the inclined plate 35 and pushes the inclined plate 35 to rotate at the end of the support plate 33. When the inclined plate 35 moves, it pushes the pressing plate 31 to move towards the surface of the tree seedling 4. When the pressing plate 31 moves, it presses the tree seedling 4 through the sponge pad 32, improving the stability of the tree seedling 4 during transplanting and transportation, and preventing the tree seedling 4 from being damaged due to shaking. If there is a collision, the bottom of the right-angle plate 34 will contact the top of the soil pot 5. The right-angle plate 34 will press the soil pot 5 into the inside of the cylindrical frame 15, further improving the stability of the seedling 4 during transplanting and transportation. When the cylindrical frame 15 tilts outward with the rotating rod 12, the lifting plate 23 will separate from the inclined pressure plate 21. The lifting plate 23 will slide downward using the weight of the seedling 4. At this time, the spring piece 30 will pull the bottom of the inclined plate 35 to move towards the surface of the cylindrical frame 15. At this time, the pressing plate 31 will pull the sponge pad 32 to separate from the surface of the seedling 4, making it easier for workers to take the seedling 4 out of the inside of the cylindrical frame 15, improving the convenience of transplanting the seedling 4. During the resetting operation, the bearing plate 13 will cause the pressure plate 11 to contact the force plate 47 and push the force plate 47 to rotate. When the force plate 47 rotates, it will squeeze the elastic rod 46 to move inward towards the center plate 1. When the elastic rod 46 moves, it will push the triangular push plate 45 to slide inward towards the through hole 44. When the triangular push plate 45 moves, it will contact the center of the movable triangular plate 43 and push its center upward. When the center of the movable triangular plate 43 moves, its end will push the rectangular frame 41 to move towards the surface of the tree seedling 4. When the rectangular frame 41 moves, it will squeeze the tree seedling 4 through the rectangular sponge pad 42. The rectangular frame 41 will squeeze and limit the branches of the tree seedling 4, improving the stability of the tree seedling 4 during transplanting and transportation. The bearing plate 13 and the rectangular frame 41 cooperate with each other to avoid the tree seedling 4 from shaking violently during transplanting and transportation.
