Description

Technical Field

[0001] The invention relates to the technical field of tree planting, in particular to a tree planting device. Background Art

[0002] Modern forestry is developing rapidly, and tree planting technology is constantly innovating. However, in the actual planting process, we often encounter problems such as unstable growth and easy lodging of trees, especially under harsh climatic conditions, which increases the difficulty and cost of management. Traditional fixing methods mainly use materials such as wooden stakes or wire mesh to fix trees. However, these methods have problems such as unstable fixing, easy corrosion, and high maintenance costs, which cannot meet the needs of modern forestry for efficient and stable planting.

[0003] At present, traditional planting devices are used to directly fix the trunks of trees. After the trees are planted, the soil near their roots is relatively loose, which can easily cause the trees to tilt. Moreover, when bad weather comes, the reinforcement device can only reinforce the fixed position of the trees. When external wind blows the trees, the reinforced position can only resist the external force, which can easily cause the trees at the reinforced position to break, affecting the survival rate of the trees.

[0004] In view of this, we propose a tree planting device. Summary of the invention

[0007] A leveling assembly is provided on one side of the rack, and the leveling assembly is used to level the soil at the tree planting location. When the piston rod at the end of the cylinder drives the rotating rod to rotate, the rack drives the leveling assembly downward to squeeze the soil at the tree planting location, thereby increasing the stability of the tree roots.

[0009] As a further improvement of the technical solution, a third elastic member is provided on the surface of the connecting column, and both ends of the third elastic member are respectively connected to the bottom of the movable seat and the bevel gear plate. In a natural state, the bevel gear plate is moved away from the horizontal plane by the force of the third elastic member.

[0010] As a further improvement of the technical solution, a reinforcement plate is provided on the side wall of the rotating rod, and the reinforcement plate is used to increase the physical strength of the rotating rod so that the rotating rod maintains stability in extreme weather.

[0011] As a further improvement of the technical solution, the automatic clamping assembly includes a sliding column arranged at the through groove, an arc plate is slidably provided on the inner wall of the sliding column, and a second elastic member is provided between the sliding column and the arc plate.

[0012] As a further improvement of the technical solution, an auxiliary plate is provided at the bottom of the support block, an electric telescopic rod is provided on the surface of the auxiliary plate, a tool is provided on the top of the electric telescopic rod, and the diameter distance between the tools is greater than the diameter between the leveling components.

[0013] As a further improvement of the present technical solution, the fixing assembly includes a base plate rotatably arranged at the end of the rotating block, a motor is provided on the back of the base plate, and the motor drives a belt shaft at the end of a screw rod arranged on the surface of the base plate to rotate through a belt, the thread on the surface of the screw rod is symmetrical, and a splint is provided on the surface of the screw rod.

[0014] As a further improvement of the technical solution, a gasket is provided on the inner side of the splint, and the gasket is made of rubber material to reduce the pressure damage to the surface of the trunk when the splint is used to limit and fix the trunk of the tree.

[0015] As a further improvement of the technical solution, the rotating block and the base plate are rotatably connected, and when fixing the trees, the base plate is rotated so that the clamping plates provided at its ends cross-fix the trunks of the trees.

[0018] 2. In the tree planting device, the motor output shaft drives the belt shaft at the end of the screw rod to rotate through the belt, and the splints provided on the surface of the screw rod move relatively, so as to adaptively clamp and fix according to the thickness of the tree trunk, thereby realizing the rapid fixation of trees of different sizes. When the external wind force is strong, the trees are squeezed against the base plate by the wind force, and the base plate drives the rotating block to rotate on the surface of the rotating rod under the action of external force. The surface of the rotating rod is provided with a first elastic part to prevent the trees from directly resisting the wind force, thereby improving the compression resistance of the trees and increasing the survival rate of the trees.

[0019] 3. In the tree planting device, when the cylinder pushes the rotating rod to approach the tree trunk, the base plate is rotated to form a cross shape. When fixing the tree, the belt shaft at the end of the screw rod is driven to rotate through the belt through the motor output shaft, so that the clamping plate on the surface of the screw rod clamps the tree trunk in a cross shape, thereby improving the stability of the trunk clamping and fixing.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] The purpose of this embodiment is to provide a tree planting device, referring to Figure 1-Figure 8As shown, it includes a moving seat 100, a cylinder 101 is provided on one side of the moving seat 100, the two moving seats 100 are rotatably connected by a hinge and enclosed in the middle to form a through slot, an automatic clamping assembly 300 is provided at the through slot, and the automatic clamping assembly 300 is used to automatically limit the bottom of the tree, a magnetic suction piece is provided at the end of the moving seat 100 away from the hinge, a rotating rod 200 is rotatably provided on the surface of the moving seat 100, and teeth 201 are arranged evenly in an array, and a rotating rod 200 is provided below the rotating rod 200. There is a rack 102, teeth 201 meshing with the rack 102, the piston rod at the end of the rotating cylinder 101 is connected to the side wall of the rotating rod 200, a support block 203 is provided on the top of the rotating rod 200, a rotating rod is provided on the inner wall of the supporting block 203, a rotating block 204 is rotatably provided on the surface of the rotating rod, a first elastic member 205 is provided on the surface of the rotating rod, the two ends of the first elastic member 205 are respectively connected to the rotating block 204 and the inner wall of the supporting block 203, a fixing assembly 500 is rotatably provided at the end of the rotating block 204, and the fixing assembly 500 is used to fix the trunk of the forest tree;

[0038] A leveling assembly 400 is provided on one side of the rack 102, and the leveling assembly 400 is used to level the soil at the tree planting site. When the piston rod at the end of the cylinder 101 pushes the rotating rod 200 to rotate, the rack 102 pushes the leveling assembly 400 downward to squeeze the soil at the tree planting site, thereby increasing the stability of the tree roots.

[0039] The improvement of this embodiment is that during the rotation of the rotating rod 200, the teeth 201 drive the rack 102 to move horizontally. During the movement, the teeth 201 squeeze the wedge block 401, so that the connecting column 402 arranged below the wedge block 401 drives the conical tooth plate 404 to move downward. Since the bottom of the conical tooth plate 404 is conical, the pressure between the soil is increased when squeezing the soil, thereby automatically pressing and compacting the loose soil near the trees, thereby improving the stability of the tree roots and reducing the labor of operators.

[0040] The output shaft of the motor 502 drives the belt shaft at the end of the screw rod 503 to rotate through the belt, and the clamping plate 504 provided on the surface of the screw rod 503 moves relatively, so as to adaptively clamp and fix according to the thickness of the tree trunk, thereby realizing rapid fixation of trees of different sizes. When the external wind force is strong, the trees are squeezed against the base plate 501 by the wind force, and the base plate 501 drives the rotating block 204 to rotate on the surface of the rotating rod under the action of external force. The surface of the rotating rod is provided with a first elastic member 205 to prevent the trees from directly resisting the wind force, thereby improving the pressure resistance of the trees and increasing the survival rate of the trees.

[0041] Considering that the soil near the trees is relatively loose when the trees are planted, it is necessary to compact the soil near the trees manually, which increases the labor intensity of the operators. Therefore, the leveling assembly 400 includes a wedge block 401 arranged on one side of the rack 102, a through groove is provided below the wedge block 401, the wedge block 401 slides on the inner wall of the through groove, a connecting column 402 is provided at the bottom of the wedge block 401, and a bevel tooth plate 404 is provided at the bottom of the connecting column 402. When the planted trees are fixed and limited, the piston rod at the end of the cylinder 101 pushes the rotating rod 200 The rotating rods 200 rotate and move closer to each other on both sides of the tree trunks, so that the trees form a triangular stable structure. During the rotation of the rotating rods 200, the teeth 201 drive the rack 102 to move horizontally. During the movement, the teeth 201 squeeze the wedge block 401, so that the connecting column 402 arranged under the wedge block 401 drives the conical tooth plate 404 to move downward. Since the bottom of the conical tooth plate 404 is conical, the pressure between the soil is increased when squeezing the soil, thereby automatically pressing and compacting the loose soil near the trees, reducing the labor of operators.

[0042] When the tree planting is completed, the forest pit dug during the planting needs to be backfilled. However, during the backfilling process, the soil near the trees is uneven, which can easily lead to soil loss during the rainy season and affect the stability of tree planting. Therefore, a third elastic member 403 is provided on the surface of the connecting column 402, and the two ends of the third elastic member 403 are respectively connected to the bottom of the moving seat 100 and the conical tooth plate 404. In the natural state, the conical tooth plate 404 is moved away from the horizontal plane by the force of the third elastic member 403. The moving seat 100 drives the conical tooth plate 404 to move during the movement. The conical tooth plate 404 flattens the soil in the uneven places of the trees during the movement, thereby avoiding soil loss in the rainy season and improving the stability of tree planting.

[0043] Taking into account that in extreme weather, when the wind is strong, the rotating rod 200 is easily subjected to large force and deformed, affecting the service life of the device, a reinforcement plate 202 is provided on the side wall of the rotating rod 200. The reinforcement plate 202 is used to increase the physical strength of the rotating rod 200 so that the rotating rod 200 maintains stability in extreme weather. When the weather is windy in extreme weather, the reinforcement plate 202 is provided on the side wall of the rotating rod 200. The physical strength of the rotating rod 200 is enhanced by the reinforcement plate 202, thereby avoiding bending and deformation of the rotating rod 200 during the blowing process, thereby improving the stability of the device.

[0044] When fixing the trees, in order to prevent the trees from tilting and falling, which would require secondary planting and affect the planting efficiency, the automatic clamping assembly 300 includes a slide column 301 arranged at the through groove, an inner wall of the slide column 301 is provided with an arc plate 302 for sliding, and a second elastic member 303 is provided between the slide column 301 and the arc plate 302. When the movable seat 100 is moved to the tree, when the tree is located at the through groove formed between the movable seats 100, the trunk of the tree squeezes the arc plate 302, causing the arc plate 302 to slide on the inner wall of the slide column 301. During the sliding process, the arc plate 302 squeezes the second elastic member 303 to deform it. When the trunk of the tree is between the slide columns 301, the movable seat 100 is stopped, and the arc plate 302 is acted upon by the restoring force of the second elastic member 303, exerting a reverse force on the surface of the trunk, thereby quickly limiting the position of the planted tree, preventing the tree from tilting and improving the planting efficiency.

[0045] When the weather is extremely bad after the planting is completed, in order to prevent the trees from being destroyed in the middle and causing the trees to die, an auxiliary plate 206 is provided at the bottom of the support block 203, and an electric telescopic rod 207 is provided on the surface of the auxiliary plate 206. A tool 208 is provided on the top of the electric telescopic rod 207. The diameter distance between the tools 208 is greater than the diameter between the leveling components 400. By adjusting the tool 208 to a suitable height position on the electric telescopic rod 207, when extreme weather comes, the swing amplitude of the trees above the automatic clamping component 300 is too large, which is easy to cause damage to the tree trunks on the one hand, and on the other hand, it is easy to cause damage to the planting device. By setting the tool 208 above the automatic clamping component 300, when the swing amplitude of the trees is too large, the tree trunks hit the tool 208. Under multiple impacts, the tool 208 damages the top of the trunk, thereby breaking the trees at the tool 208 through wind force. After the trees are broken, they can still survive through subsequent care, thereby improving the survival rate of trees in extreme weather.

[0046] When fixing trees, since the thickness of tree trunks varies, in order to facilitate the rapid fixing of tree trunks and form a stable triangular structure, the fixing component 500 includes a base plate 501 rotatably arranged at the end of a rotating block 204, and a motor 502 is arranged on the back of the base plate 501. The motor 502 drives the belt shaft at the end of a screw rod 503 arranged on the surface of the base plate 501 to rotate through a belt. The thread on the surface of the screw rod 503 is symmetrical, and a splint 504 is arranged on the surface of the screw rod 503. The output shaft of the motor 502 drives the belt shaft at the end of the screw rod 503 to rotate through a belt, and the splint 504 arranged on the surface of the screw rod 503 moves relative to each other, thereby adaptively clamping and fixing according to the thickness of the tree trunks, thereby realizing rapid fixation of trees of different sizes and improving the practicability of the planting device in use.

[0047] Taking into account that tree trunks are relatively fragile, the epidermis of the trunks may be easily damaged during the clamping process, which may affect the health of the trunks. Therefore, gaskets 505 are provided on the inner side of the splints 504. The gaskets 505 are made of rubber. When the splints 504 are used to limit and fix the tree trunks, the pressure on the surface of the trunks is reduced. By arranging gaskets 505 on the inner side of the splints 504, the gaskets 505 fit with the surface of the trunks when the surface of the trees is clamped and fixed. Since the gaskets 505 have strong plasticity, they can be adaptively fine-tuned according to the curvature of the trunks when fitting with the surface of the trunks, thereby increasing the contact area with the trunks, thereby avoiding damage to the epidermis of the trunks during clamping and fixing, and ensuring the health of the trunks.

[0048] In order to improve the stability of the tree trunk clamping, the rotating block 204 and the base plate 501 are rotatably connected. When fixing the tree, the base plates 501 are cross-shaped to fix the tree trunk through the clamping plates 504. When the cylinder 101 pushes the rotating rod 200 close to the tree trunk, the base plates 501 are rotated to form a cross. When fixing the tree, the belt shaft at the end of the screw rod 503 is driven to rotate through the belt through the output shaft of the motor 502, so that the clamping plates 504 on the surface of the screw rod 503 are cross-shaped to clamp the tree trunk, thereby improving the stability of the tree trunk clamping.

[0049] In summary, the working principle of the present invention is as follows: the movable seat 100 is pushed to rotate around the tree planting location, and the movable seat 100 drives the bevel tooth plate 404 to move during the movement. The bevel tooth plate 404 flattens and tidies the soil at the uneven locations of the trees during the movement, thereby avoiding soil loss in the rainy season and improving the stability of tree planting. After the soil near the trees is sorted, external force is applied to both sides of the movable seat 100 to open the movable seat 100, and the movable seat 100 is pushed to the trees to form an enclosure. At this time, the trunks of the trees are in an arc-shaped The plate 302 is squeezed to make the arc plate 302 slide on the inner wall of the sliding column 301. The arc plate 302 squeezes the second elastic member 303 during the sliding process to deform it. When the trunk of the tree is between the sliding columns 301, the moving seat 100 stops pushing. The arc plate 302 is acted upon by the restoring force of the second elastic member 303, and exerts a reverse force on the surface of the trunk, thereby quickly limiting the position of the planted trees to prevent the trees from tilting. In order to quickly fix the trunk, the piston rod at the end of the cylinder 101 pushes the rotating rod 200 to rotate. The rotating rods 200 are close to each other to both sides of the tree trunks, so that the trees form a triangular stable structure. At this time, the output shaft of the motor 502 drives the belt shaft at the end of the screw rod 503 to rotate through the belt, and the clamping plate 504 provided on the surface of the screw rod 503 moves relatively, so as to adaptively clamp and fix according to the thickness of the tree trunks, thereby realizing fast fixation of trees of different sizes. When the external wind force is strong, the trees are squeezed on the base plate 501 by the wind, and the base plate 501 drives the rotating block 204 to rotate on the surface of the first elastic member 205 under the action of external force, so as to avoid the trees from being stuck. The wood directly resists the wind force, thereby improving the compression resistance of the trees and increasing the survival rate of the trees. At the same time, during the rotation of the rotating rod 200, the teeth 201 drive the rack 102 to move horizontally. The teeth 201 squeeze the wedge block 401 during the movement, so that the connecting column 402 arranged under the wedge block 401 drives the conical tooth plate 404 to move downward. Since the bottom of the conical tooth plate 404 is conical, the pressure between the soil is increased when squeezing the soil, thereby automatically pressing and compacting the loose soil near the trees, reducing the labor of the operators.
