Description

Technical Field

[0001] The invention relates to the technical field of planting equipment, and in particular to a tree planting auxiliary positioning device for ecological construction. Background Art

[0002] Soil and water conservation refers to the preventive and control measures taken against soil erosion caused by natural factors and human activities. When planting vegetation, it is necessary to first dig a pit in the planting area, drill holes around the soil where the roots of the large trees to be transplanted are distributed, irrigate the roots with water, make the soil around the roots into a slurry, wrap the roots of the trees, and then use a crane to pull up the large trees with their roots. The soil ball at the roots of the trees is pulled up along with the roots and transplanted to a new planting site. This can avoid damaging the roots and make them survive as soon as they are planted. This is suitable for trees that are difficult to transplant and survive, such as pine trees. Usually during the transplanting process, the trees are only clamped, and the soil ball under the roots of the trees will drop a lot of soil due to the shaking of the transportation vehicle during the movement, so that the roots of the trees lose protection, which is not easy to improve the survival rate of the trees.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 12 :

[0034] A tree planting auxiliary positioning device for ecological construction includes a machine base 1 installed on a transport device, a clamping clamp 2 installed on the machine base 1 for clamping a tree, a first linear drive 11 for driving the clamping clamp 2 to rise and fall in a vertical direction, and a root positioning cage 3 for clamping a soil ball at the root of the tree. The machine base 1 is provided with a telescopic arm 12 for driving the root positioning cage 3 to move horizontally. The root positioning cage 3 includes a fixing ring 31 installed at the free end of the telescopic arm 12, and a supporting base 32 for fitting the bottom of the soil ball is coaxially installed on the fixing ring 31. A plurality of protective plates 33 are hingedly installed on the side of the fixing ring 31, and the hinge axis of the protective plate 33 is arranged horizontally; the root positioning cage 3 also includes an adjusting ring 34 coaxially arranged with the fixing ring 31, the inner diameter of the adjusting ring 34 is larger than the outer diameter of the fixing ring 31, and a lifting seat 35 is slidably installed on the fixing ring 31, and the lifting seat 35 moves in the vertical direction to drive the adjusting ring 34 to move in the vertical direction. When the lifting seat 35 moves up to the inner wall of the adjusting ring 34 and fits the outer wall of the protective plate 33, it drives the protective plate 33 to flip upward, and the protective plate 33 fits the side of the soil ball to clamp and position the sapling soil ball.

[0035] The present application installs the machine base 1 on a suitable transport device to ensure the stable movement of the entire device, operates the first linear drive 11, and makes the clamp 2 descend to a suitable height to clamp and fix the tree. The first linear drive 11 can be a linear slide. Then, the tree is lifted, the telescopic arm 12 is started, and the root positioning cage 3 is driven to move horizontally to move directly below the soil ball at the root of the tree. The first linear drive 11 is operated to make the clamp 2 holding the tree descend, and the soil ball at the root of the tree is placed on the support base 32, at which time the bottom of the soil ball fits the support base 32. Then, the lifting seat 35 is controlled to move up in the vertical direction, and the lifting seat 35 drives the adjustment ring 34 to move up in the vertical direction. When the inner wall of the adjustment ring 34 fits the outer wall of the protective plate 33, since the protective plate 33 is hingedly mounted on the fixing ring 31 and the hinge axis is horizontally arranged, the upward movement of the adjustment ring 34 will drive the protective plate 33 to flip upward until the protective plate 33 fits the surrounding side of the soil ball, thereby clamping and positioning the sapling soil ball. After the trees and soil balls are fixed, the trees are transported to the new planting site by means of transportation equipment. After arriving at the new planting site, the lifting seat 35 is first controlled to move downward so that the adjustment ring 34 is separated from the protective plate 33, and the protective plate 33 is flipped downward and opened under the action of gravity. Then the first linear drive 11 is operated to raise the clamping clamp 2, and the tree and the soil ball are removed from the root positioning cage 3. The telescopic arm 12 drives the root positioning cage 3 to be recovered, so as to facilitate the subsequent planting operation. In this embodiment, the root positioning cage 3 is attached to the bottom of the soil ball through the support base 32, and the protective plate 33 is attached to the side of the soil ball to clamp and position the soil ball, which can effectively prevent the soil ball from scattering during transportation, provide good protection for the roots of the trees, and thus improve the survival rate of the trees after transplantation. The telescopic arm 12 arranged on the machine base 1 can drive the root positioning cage 3 to move horizontally, so as to facilitate the root positioning cage 3 to accurately move to the bottom of the tree root soil ball, and adapt to the tree soil balls in different positions. At the same time, the opening and closing of the protective plate 33 is achieved by controlling the up and down movement of the lifting seat 35, which is simple to operate and convenient for quickly completing the wrapping and removal of the soil ball. The telescopic arm 12 set on the machine base 1 can drive the root positioning cage 3 to move horizontally, so that the root positioning cage 3 can be accurately moved to the bottom of the tree root soil ball to adapt to the tree soil ball in different positions. At the same time, the opening and closing of the protective plate 33 is achieved by controlling the up and down movement of the lifting seat 35, which is simple to operate and convenient for quickly completing the wrapping and release of the soil ball. The root positioning cage 3 is composed of a fixed ring 31, a support base 32, a protective plate 33, an adjustment ring 34 and a lifting seat 35, and the structure is compact and reasonable. The protective plate 33 is hingedly mounted on the fixed ring 31, and the flipping of the protective plate 33 is achieved by the up and down movement of the adjustment ring 34. The wrapping degree can be adaptively adjusted according to the size of the soil ball, and it has good versatility.

[0036] In order to improve the fit of the support base 32 to the bottom of the soil ball and enable it to automatically reset after leaving the soil ball, the following features are specifically set:

[0037] The top of the support base 32 is arranged in an arc shape, and a plurality of first guide rods 321 extending vertically downward are arranged at the bottom of the support base 32. The first guide rods 321 are inserted into the first guide sleeve 311 arranged on the inner wall of the fixing ring 31. A first spring 322 is sleeved on the first guide rod 321. The first spring 322 elastically connects the first guide sleeve 311 and the fixing ring 31. The bottoms of all the first guide rods 321 are fixedly connected through the bottom plate 323. The elastic force of the first spring 322 causes the support base 32 and the bottom plate 323 to move up until the bottom plate 323 fits the bottom of the first guide sleeve 311.

[0038] Before placing the soil ball at the root of the tree on the support base 32, due to the elastic force of the first spring 322, the support base 32 and the bottom plate 323 are in an upward state, and the bottom plate 323 fits the bottom of the first guide sleeve 311. At this time, the support base 32 is in a relatively high initial position. When the first linear drive 11 is operated to lower the clamping clamp 2 holding the tree, and the soil ball at the root of the tree is placed on the support base 32, the gravity of the soil ball will be applied to the support base 32. As the weight of the soil ball gradually acts, the support base 32 will overcome the elastic force of the first spring 322 and slide downward in the first guide sleeve 311 along the first guide rod 321. The first spring 322 is compressed, and the support base 32 will adaptively adjust its position according to the shape and weight of the soil ball to better fit the bottom of the soil ball. During transportation, the support base 32 is continuously subjected to the pressure of the soil ball and maintains a state of close fit with the bottom of the soil ball. The first spring 322 is in a compressed state to provide stable support for the soil ball. In this embodiment, when the soil ball is removed from the support base 32, the elastic force of the first spring 322 will automatically move the support base 32 and the bottom plate 323 upward and reset. After each use, the support base 32 can be quickly restored to the initial state, and there is no need to manually adjust the position of the support base 32, which improves the use efficiency of the device and facilitates the next tree transplanting operation.

[0039] In order to achieve the purpose of automatically lifting the adjustment ring 34 to flip the protective plate 33 to fit the soil ball while the support base 32 moves downward, the following features are specifically set:

[0040] A plurality of second guide rods 341 extending vertically downward are arranged at the bottom of the adjusting ring 34 , and the second guide rods 341 are inserted into the second guide sleeves 312 arranged on the circumference of the fixing ring 31 ; a limiting ring 342 is coaxially arranged at the bottom of the adjusting ring 34 , and the limiting ring 342 connects the bottom ends of all the second guide rods 341 .

[0041] The lifting seat 35 is in an "L" shape, and the bottom of the lifting seat 35 extends horizontally to the bottom of the limit ring 342; a central gear 313 is rotatably installed at the bottom of the fixed ring 31, and the axis of the central gear 313 is horizontally arranged perpendicular to the axis of the fixed ring 31, and a vertically extending first rack 324 is arranged on the bottom plate 323, and a second rack 351 is arranged on the vertical section of the lifting seat 35, and the first rack 324 and the second rack 351 are respectively meshed and connected with the central gear 313, and the support base 32 moves downward to drive the central gear 313 to rotate, and the rotation of the central gear 313 drives the lifting seat 35 to move upward and pushes the adjusting ring 34 to move upward, so that the protective plate 33 flips upward.

[0042] In this embodiment, the staff operates the first linear drive 11 to lower the clamping clamp 2 holding the tree. When the soil ball at the root of the tree is placed on the support base 32, the gravity of the soil ball is applied to the support base 32. The support base 32 overcomes the elastic force of the first spring 322 and slides downward in the first guide sleeve 311 along the first guide rod 321, and the first rack 324 fixedly connected to the bottom of the support base 32 through the bottom plate 323 moves downward accordingly. Since the first rack 324 is meshed and connected with the center gear 313, the downward movement of the first rack 324 will drive the center gear 313 to rotate. When the center gear 313 rotates, the second rack 351 meshed with it will drive the lifting seat 35 to move upward. Because the lifting seat 35 is "L"-shaped, and its bottom extends horizontally to the bottom of the limit ring 342, the lifting seat 35 will push the limit ring 342 during the upward movement. The upward movement of the adjusting ring 34 will drive the protective plate 33 to flip upward until the protective plate 33 fits the side of the soil ball, completing the clamping and positioning of the sapling soil ball. This embodiment realizes the linkage between the downward movement of the support base 32 and the upward movement of the adjusting ring 34 through the transmission structure of the first rack 324, the central gear 313 and the second rack 351. In the process of placing the soil ball on the supporting base 32, the protective plate 33 can automatically wrap the soil ball without additional operation, which simplifies the operation process and improves work efficiency.

[0043] In order to avoid the problem that the protective plate 33 clamps the soil ball too hard and causes the soil ball to break, the following features are specifically set:

[0044] A detection block 352 is arranged above the horizontal section of the lifting seat 35, and a third guide rod 353 extending vertically downward is arranged at the bottom of the detection block 352. The third guide rod 353 is inserted into the lifting seat 35, and a second spring 354 is sleeved on the third guide rod 353. The second spring 354 elastically connects the detection block 352 and the lifting seat 35, and the elastic force of the second spring 354 causes the detection block 352 to move upward; a sensing unit 355 is fixedly installed on the lifting seat 35, and the working end of the sensing unit 355 is located below the detection block 352, and the sensing unit 355 is connected to the first linear driver 11 through a controller signal.

[0045] In this embodiment, when the soil ball is not placed, the detection block 352 moves upward under the elastic force of the second spring 354, keeps a certain distance from the sensing unit 355, the sensing unit 355 is not triggered, and the first linear drive 11 works normally. When the soil ball at the root of the tree is placed on the support base 32, the gravity of the soil ball causes the support base 32 to move downward, and the lifting seat 35 moves upward through the transmission of the first rack 324, the central gear 313 and the second rack 351. The lifting seat 35 moves upward and pushes the limit ring 342 and the adjustment ring 34 to move upward, thereby causing the protective plate 33 to flip upward and fit the soil ball. As the protective plate 33 clamps the soil ball, the soil ball will generate a reaction force on the protective plate 33, and this force is transmitted to the detection block 352 through the adjustment ring 34, the limit ring 342 and the lifting seat 35. When the clamping force of the protective plate 33 on the soil ball gradually increases, the reaction force of the soil ball causes the detection block 352 to overcome the elastic force of the second spring 354 and move downward. When the detection block 352 moves down to the working end of the contact sensing unit 355, the sensing unit 355 is triggered. After the sensing unit 355 is triggered, the signal is transmitted to the controller. The controller sends a signal to the first linear drive 11 according to a preset program to control the first linear drive 11 to stop the descending action, so as to prevent the protective plate 33 from continuing to move up to increase the clamping force on the soil ball and prevent the soil ball from breaking. The sensing unit 355 in this embodiment can be a contact sensor. The pressure detection mechanism composed of the detection block 352, the second spring 354 and the sensing unit 355 can monitor the clamping force of the soil ball by the protective plate 33 in real time. When the clamping force reaches the critical value that may cause the soil ball to break, the first linear drive 11 is promptly controlled to stop the action to avoid excessive clamping, effectively protect the integrity of the soil ball, and improve the survival rate of tree transplantation.

[0046] In order to ensure the stable meshing connection between the first rack 324 and the second rack 351 and the central gear 313, the following features are specifically provided:

[0047] A plurality of fourth guide rods 314 extending vertically downward are disposed below the fixing ring 31 . The fourth guide rods 314 are inserted into the horizontal section of the lifting seat 35 and extend to the bottom of the lifting seat 35 .

[0048] The fourth guide rod 314 of this embodiment is inserted into the horizontal section of the lifting seat 35, providing a stable guide for the movement of the lifting seat 35. When the first rack 324 drives the central gear 313 to rotate, and then the second rack 351 drives the lifting seat 35 to move, the lifting seat 35 can be prevented from shaking, deflecting, etc., ensuring that the first rack 324, the second rack 351 and the central gear 313 always maintain the correct meshing position and transmission relationship, making the entire transmission process more stable and reliable.

[0049] In order to achieve the purpose of horizontal movement of the root positioning cage 3, the following features are specifically set:

[0050] The telescopic arm 12 includes a fixed slide rail 121 fixedly mounted on the machine base 1, and a movable arm 122 slidably mounted in the fixed slide rail 121. The fixed slide rail 121 is located directly below the clamping clamp 2. The fixed slide rail 121 and the movable arm 122 extend along the length direction of the clamping clamp 2. The end of the movable arm 122 away from the fixed slide rail 121 is fixedly connected to a connecting frame 315 provided on the fixed ring 31; the connecting frame 315 is located below the fixed ring 31 and the adjusting ring 34.

[0051] The upper side of the movable arm 122 is provided with teeth grooves 123 arranged at equal intervals along the length direction of the movable arm 122, and a driving gear 124 is rotatably installed at one end of the fixed slide rail 121 close to the root positioning cage 3. The driving gear 124 is meshed and connected with the teeth grooves 123 on the movable arm 122, and a rotating driver 125 for driving the driving gear 124 to rotate is also fixedly installed on the fixed slide rail 121.

[0052] The fixed rail 121 in the telescopic arm 12 is fixedly mounted on the base 1 and is located directly below the clamp 2. The movable arm 122 is partially received in the fixed rail 121, and the root positioning cage 3 is in an initial position close to the base 1. The driving gear 124 is in meshing with the tooth groove 123 on the movable arm 122. When it is necessary to move the root positioning cage 3 to directly below the root ball of the tree, the rotary driver 125 is started. The rotary driver 125 drives the driving gear 124 to rotate. Since the driving gear 124 is meshed and connected with the tooth groove 123 on the movable arm 122, the rotation of the driving gear 124 drives the movable arm 122 to slide along its length direction in the fixed rail 121. The end of the movable arm 122 away from the fixed rail 121 is fixedly connected to the fixed ring 31 through the connecting frame 315, so the sliding of the movable arm 122 drives the root positioning cage 3 to move in the horizontal direction until the root positioning cage 3 reaches directly below the root ball of the tree. Through the structural design of the telescopic arm 12, the rotary driver 125 drives the driving gear 124 to mesh with the tooth groove 123 on the movable arm 122, so that the root positioning cage 3 can be easily and accurately moved in the horizontal direction. This allows the root positioning cage 3 to be flexibly moved to the position directly below the tree root ball, adapting to the needs of transplanting trees in different positions, and improving the operational flexibility and applicability of the device. The fixed slide rail 121 is located directly below the clamping clamp 2, and the connecting frame 315 is located below the fixed ring 31 and the adjusting ring 34. This spatial layout makes the structure of the device more compact and avoids mutual interference between the components. The rotary driver 125 can be a servo motor.

[0053] In order to achieve the purpose of retracting the protective plate 33 when the root positioning cage 3 follows the telescopic arm 12 to move into the machine base 1, the following features are specifically provided:

[0054] At least one contact plate 343 is fixedly installed below the adjusting ring 34, and the contact plate 343 is horizontally arranged along the length direction of the telescopic arm 12; a lifting plate 126 is fixedly installed at the bottom of the fixed slide rail 121 and is in the same horizontal line as the contact plate 343, and an inclined surface is arranged at one end of the lifting plate 126 away from the fixed slide rail 121. When the root positioning cage 3 moves toward the machine base 1, the contact plate 343 contacts the inclined surface of the lifting plate 126, driving the adjusting ring 34 to move along the surface of the lifting plate 126 and move upward, so that all the protective plates 33 are flipped upward and retracted.

[0055] After the tree transplanting is completed in this embodiment, the root positioning cage 3 needs to be moved back to the machine base 1. The rotary driver 125 is started, the driving gear 124 rotates, and the moving arm 122 is driven to slide in the fixed slide rail 121 toward the machine base 1, so that the root positioning cage 3 moves toward the machine base 1 along with the moving arm 122. As the root positioning cage 3 moves toward the machine base 1, the contact plate 343 below the adjustment ring 34 gradually approaches the lifting plate 126. When the contact plate 343 contacts the inclined surface of the lifting plate 126 away from the fixed slide rail 121, due to the guiding effect of the inclined surface, the contact plate 343 will move upward along the inclined surface of the lifting plate 126. In the process of the contact plate 343 moving upward along the inclined surface of the lifting plate 126, the adjustment ring 34 will be driven to move upward. Because the adjustment ring 34 contacts the outer wall of the protective plate 33, when the adjustment ring 34 moves upward, it will push the protective plate 33 to flip upward. As the adjustment ring 34 continues to move upward, all the protective plates 33 gradually flip upward and shrink until the root positioning cage 3 moves to a suitable position, and the protective plates 33 complete the folding action. In this embodiment, through the cooperation of the contact plate 343 and the lifting plate 126, the protective plates 33 can be automatically folded in the process of the root positioning cage 3 moving toward the machine base 1. The protective plates 33 are folded when the root positioning cage 3 moves into the machine base 1, which effectively reduces the overall volume and occupied space of the root positioning cage 3, reduces the possibility of collision or scratching with surrounding objects during the storage and transportation of the device, and avoids damage to the protective plates 33. In addition, when the root positioning cage 3 is folded, the adjustment ring 34 is directly lifted in this embodiment without affecting the position of the lifting seat 35, so that the support base 32 will not be driven to move downward to compress the first spring 322, thereby protecting the service life of the first spring 322.

[0056] In order to facilitate the positioning of trees during transplanting, the following features are specifically set:

[0057] A laser lamp 316 is fixedly installed at the bottom of the fixing ring 31 , and the working end of the laser lamp 316 is arranged vertically downward. The laser emitted by the laser lamp 316 is used to assist in positioning the tree clamped by the clamping pliers 2 .

[0058] In this embodiment, when the laser lamp 316 installed at the bottom of the fixed ring 31 is turned on, its working end emits a laser beam vertically downward. At this time, the laser beam will be projected on the ground of the transplanting site to form an obvious light spot. Move the tree to above the approximate transplanting position. During this process, the laser lamp 316 is always kept on, and the laser beam it emits will move with the movement of the root positioning cage 3. The operator observes the position of the light spot projected by the laser lamp 316 on the ground and uses it as a reference point. According to the pre-planned tree transplanting position, adjust the position of the device so that the laser spot falls accurately on the target transplanting position. Once the light spot position is correctly determined, it means that the tree clamped by the clamp 2 is directly above the appropriate transplanting position. The root positioning cage 3 can then be withdrawn and the tree can be transplanted.

[0059] Working principle: Install the base 1 on a suitable transport device to ensure the stable movement of the entire device, operate the first linear drive 11, and lower the clamp 2 to a suitable height to clamp and fix the tree. Then lift the tree, start the telescopic arm 12, and drive the root positioning cage 3 to move horizontally to the bottom of the soil ball at the root of the tree. Operate the first linear drive 11 to lower the clamp 2 holding the tree, and place the soil ball at the root of the tree on the support base 32, at which time the bottom of the soil ball fits the support base 32. Then control the lifting seat 35 to move up in the vertical direction, and the lifting seat 35 drives the adjustment ring 34 to move up in the vertical direction. When the inner wall of the adjustment ring 34 fits the outer wall of the protective plate 33, since the protective plate 33 is hingedly installed on the fixing ring 31 and the hinge axis is horizontally set, the upward movement of the adjustment ring 34 will drive the protective plate 33 to flip upward until the protective plate 33 fits the surrounding side of the soil ball, thereby clamping and positioning the sapling soil ball. After the tree and the soil ball are fixed, the tree is transported to a new planting site by means of a transport device. After arriving at the new planting site, the lifting seat 35 is first controlled to move downward, so that the adjustment ring 34 is separated from the protective plate 33, and the protective plate 33 is flipped downward and opened under the action of gravity. Then the first linear drive 11 is operated to raise the clamp 2, and the tree and the soil ball are removed from the root positioning cage 3, and the telescopic arm 12 drives the root positioning cage 3 to be recovered, so as to facilitate the subsequent planting operation.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
