Description

Technical Field

[0001] The invention relates to the technical field of tree planting equipment, in particular to a tree planting device with surrounding and rapid soil covering for afforestation. Background Art

[0002] When using semi-mature trees for afforestation, the trees are usually hoisted to the top of the foundation pit through a lifting mechanism, and then the position of the trees is adjusted with manual assistance so that the roots of the trees can enter the foundation pit. At the same time, external force is continuously applied to the trees to keep them in an upright state, and then the soil covering work is carried out.

[0003] The traditional soil covering process typically requires multiple workers or the erection of multiple support structures to support the timber. The soil is then covered and compacted mechanically or with shovels. However, because the entire area around the timber must be covered with soil, the support structures or workers' positions often need to be adjusted during the covering process to ensure the timber receives adequate support and remains upright during transplantation. (During the covering process, soil is typically applied sequentially around the timber. The roots of the covered areas experience different forces from those in the uncovered areas. Therefore, continuous support is required throughout the entire covering process until the covering and compaction work is complete.) Frequent changes in position reduce soil covering efficiency and increase labor costs. Most importantly, the multi-stage covering process results in uneven soil compaction around the timber's roots, which can easily cause the timber to tilt after planting. Summary of the Invention

[0004] The object of the present invention is to provide a tree planting device with surrounding rapid soil covering for afforestation, so as to solve the problem proposed in the above-mentioned background technology in the traditional soil covering process, which usually requires multiple workers or the establishment of multiple support structures to form support around the wood, and then the soil is covered and compacted by mechanical covering or shovel covering. However, since the wood needs to be covered with soil all around, the support structure or the workers' positions often need to be adjusted during the soil covering process to ensure that the wood can obtain sufficient support so that the wood can be transplanted in a vertical state (during the soil covering process, the soil is usually covered sequentially along the circumference of the wood. The root base of the part where the soil is covered is subject to different support forces from the part where the soil is not covered. Therefore, the entire soil covering process requires continuous support until the soil covering and compaction work is completely completed). Frequent changes in position will reduce the efficiency of soil covering on the one hand and increase labor costs on the other. Most importantly, the soil covering process is multi-stage, which will lead to uneven compaction of the soil covering around the roots of the wood, which can easily cause the wood to tilt after planting.

[0020] By scraping and pressing, the soil distribution in the foundation pit is made more even during the compaction process (since the locations with less soil distribution are easier to be pressed into the soil than the locations with more soil distribution, the locations with more soil distribution can be pushed to the locations with less soil distribution by scraping), and the degree of compaction is more uniform.

DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 7 The present invention provides a technical solution: a tree planting device with a surrounding rapid soil covering for afforestation, comprising a frame 1 with a drive, the frame 1 comprising a main body 1-1 and a first carrier 1-2 and a second carrier 1-3, the front and rear ends of the right side of the main body 1-1 respectively extending to the right, an introduction port 1-4 being formed between the first carrier 1-2 and the second carrier 1-3, the introduction port 1-4 being used to allow trees to enter between the first carrier 1-2 and the second carrier 1-3 in a vertical state;

[0031] A clamping mechanism is provided on the first carrier 1-2 and the second carrier 1-3. The clamping mechanism can clamp the tree between the first carrier 1-2 and the second carrier 1-3 and keep the tree upright.

[0032] The covering mechanism includes an incomplete gear ring 2, which is rotatably arranged at the lower end of the frame 1. The covering mechanism can control the rotation of the incomplete gear ring 2. The rotation center of the incomplete gear ring 2 is coaxial with the clamping center of the clamping mechanism. The inner side wall of the incomplete gear ring 2 is fixedly connected with a plurality of pushing devices distributed in a circular array. The pushing devices are used to push the soil toward the rotation center of the incomplete gear ring 2. The covering mechanism is used to automatically cover the clamping center axis of the clamping mechanism with soil.

[0033] Embodiment 1: During the tree planting process, the tree is lifted vertically by a crane or other means, and then the frame 1 is driven to move and the position of the frame 1 is adjusted so that the tree enters the inlet 1-4. The clamping mechanism is then activated to clamp the tree. During the clamping process, under the action of the clamping force, the tree is clamped to the clamping center of the clamping mechanism. The frame 1 is then driven to move to the foundation pit so that the root of the tree is aligned with the foundation pit. The clamping mechanism is then controlled to release the tree so that the tree falls into the foundation pit. The clamping mechanism is then controlled again to clamp the tree to correct the position and verticality of the tree.

[0034] Implementation method 2: During the tree planting process, the tree is placed directly into the foundation pit by means of a crane or other means, and then the frame 1 is driven to move to the foundation pit, and the clamping mechanism is controlled to clamp the tree, and the position and verticality of the tree are corrected;

[0035] The clamping mechanism clamps the tree and places the trunk of the tree at the rotation center of the incomplete gear ring 2, and then drives the incomplete gear ring 2 to drive multiple pushing devices to rotate around the trunk, synchronously pushing the soil near the foundation pit into the foundation pit and compacting it; after the soil covering is completed, the clamping mechanism completely separates from the tree, and finally drives the frame 1 to leave the foundation pit to plant the next tree.

[0036] Since the holding mechanism and the covering mechanism are arranged in an upper and lower layered manner, the holding mechanism avoids interfering with the work of the covering mechanism in the process of providing stable support for the tree, further avoiding the change of the support point, and also provides the necessary conditions for the coherent covering operation. Then the covering mechanism rotates around the tree trunk through multiple pushing devices to cover the tree in a circular manner, which makes the covering efficiency higher, the covering process more coherent, and the covering uniformity higher, thereby effectively improving the planting quality.

[0037] Furthermore, the clamping mechanism includes two telescopic parts 3 symmetrically arranged in the carrier 1-2, a tensioning belt 5 is arranged between the telescopic parts 3, and the two ends of the tensioning belt 5 are respectively arranged at the ends of the two telescopic parts 3; two telescopic parts 6 symmetrically arranged in the carrier 2 1-3, a tensioning belt 27 is arranged between the two telescopic parts 26, and the two ends of the tensioning belt 27 are respectively arranged at the ends of the two telescopic parts 26.

[0038] Furthermore, the ends of the telescopic member 3 are fixedly connected to the slider 4, and the two ends of the tensioning belt 5 are respectively rotatably connected to the slider 4; the ends of the telescopic member 2 6 are fixedly connected to the guide rail 8, and the side of the guide rail 8 close to the tensioning belt 2 7 is provided with a avoidance groove 8-1 for engaging the slider 4.

[0039] Furthermore, there are two tensioning belts 27, and the two ends of one tensioning belt 27 are rotatably connected to the ends of the left and right guide rails 8 above the avoidance groove 8-1, and the two ends of the other tensioning belt 27 are rotatably connected to the ends of the left and right guide rails 8 below the avoidance groove 8-1.

[0040] In the process of the clamping mechanism clamping the tree, the trunk part of the tree is firstly driven to move by the vehicle frame 1, and then the telescopic part 1 3 and the telescopic part 2 6 are started to drive the slider 4 and the guide rail 8 to move toward each other, thereby making the tension belt 1 5 and the tension belt 2 7 squeeze the front and rear sides of the trunk toward each other (two tension belts 2 7 are respectively located above and below the tension belt 1 5, and form opposite squeezing with the tension belt 1 5, so that when the tension belt 1 5 and the tension belt 2 7 squeeze the trunk, a force balance can be formed to prevent the trunk from being subjected to torsional force and causing the trunk to tilt), and the trunk is clamped; in this process, the slider 4 will enter the avoidance groove 8-1 of the guide rail 8, so that the slider 4 is engaged with the guide rail 8, and further, the stability of the movement direction of the slider 4 and the guide rail 8 is maintained during the process of the slider 4 and the guide rail 8 moving toward each other. The tree trunk is fixed, so as to avoid the vertical deformation of the slider 4 and the guide rail 8 after long-term use. Since the side walls of the tree trunk are not vertical cylindrical, when the slider 4 and the guide rail 8 hug the tree trunk through the tensioning belt, the slider 4 and the guide rail 8 will be subjected to the vertical reaction force. If the slider 4 and the guide rail 8 are independent of each other, the slider 4 and the guide rail 8 will undergo elastic deformation in the vertical direction. If this continues for a long time, the slider 4 and the guide rail 8 will produce vertical deformation, reducing the service life of the equipment; at the same time, the trunk is hugged by the strip-shaped tensioning belt 1 5 and the tensioning belt 2 7, so that the device can have a larger and evenly distributed pressure on the trunks of different diameters, and the strip-shaped tensioning belt is made of flexible material with low hardness, which is not easy to cause crushing to the trunk, thereby playing a good protective role for the tree.

[0041] Furthermore, the tensioning belt 1 5 and the tensioning belt 2 7 are fixedly connected to an elastic member 9 on one side away from the rotation center of the incomplete gear ring 2, and the carrier 1 1-2 and the carrier 2 1-3 are fixedly connected to a connecting plate 10, and the elastic member 9 is fixedly connected to the corresponding connecting plate 10 respectively.

[0042] The elastic member 9 applies a pulling force to the tensioning belt 1 5 and the tensioning belt 2 7 in the direction away from the rotation center of the incomplete gear ring 2, so that the tensioning belt 1 5 and the tensioning belt 2 7 can always be in an open state, preventing the tensioning belt 1 5 and the tensioning belt 2 7 from curling during use, resulting in holding failure or poor holding effect.

[0043] Furthermore, the covering mechanism also includes an arc track 11, which is fixedly connected to the main body 1-1, and the incomplete ring gear 2 is rotatably connected to the upper end of the arc track 11. Two motors 12 are fixedly connected to the main body 1-1, and the output shafts of the two motors 12 are both transmission-connected to the incomplete ring gear 2; the spacing between the two motors 12 is greater than the spacing between the two ends of the incomplete ring gear 2; the ends of the arc track 11 and the incomplete ring gear 2 do not extend into the inlet 1-4.

[0044] Furthermore, the pushing device includes a connecting block 13, which is fixedly connected to the inner wall of the incomplete gear ring 2. An L-shaped plate 14 is arranged below the connecting block 13. The L-shaped plate 14 consists of a straight plate 14-1 as the main body and a rocker plate 14-2 extending and tilting from one side of the straight plate 14-1. A radial driving mechanism, a rotating mechanism and an axial driving mechanism are respectively arranged between the connecting block 13 and the L-shaped plate 14; the radial driving mechanism is used to drive the L-shaped plate 14 to move radially along the incomplete gear ring 2; the rotating mechanism is used to drive the L-shaped plate 14 to rotate around the connecting block 13; and the axial driving mechanism is used to drive the L-shaped plate 14 to rotate axially about the rotation axis of the L-shaped plate 14.

[0045] Furthermore, the radial drive mechanism includes a slide block 15, which is fixedly connected to the lower end of the connecting block 13. The lower end of the slide block 15 is radially slidably connected to a slide rod 16 along the incomplete gear ring 2. The lower end of the slide rod 16, close to the rotation center of the incomplete gear ring 2, is fixedly connected to an I-beam 17, and the L-shaped plate 14 is arranged below the I-beam 17; the end of the slide rod 16 away from the rotation center of the incomplete gear ring 2 is provided with a motor 2 18, and the output shaft of the motor 2 18 is fixedly connected to a screw 19, which is located below the slide rod 16 and parallel to the slide rod 16. The end of the slide rod 16 is fixedly connected to a nut block 20, and a thread groove 20-1 is opened through the nut block 20, and the screw 19 is threadedly connected to the thread groove 20-1.

[0046] The screw 19 is driven to rotate by the motor 2 18, thereby driving the nut block 20 to move axially along the screw 19. Further, the nut block 20 drives the slide rod 16 to move radially along the incomplete gear ring 2, and the slide rod 16 drives the I-beam 17 and the mechanism below the I-beam 17 to move radially along the incomplete gear ring 2.

[0047] Furthermore, the rotating mechanism includes a U-shaped steel 21, the inner wall of the upper end of the U-shaped steel 21 is fixedly connected to a motor three 22, the lower side wall of the U-shaped steel 21 is rotatably connected to a vertically arranged connecting shaft 23, the output shaft of the motor three 22 is transmission-connected to the upper end of the connecting shaft 23, and the lower end of the connecting shaft 23 is connected to the side wall of the L-shaped plate 14.

[0048] The motor 3 22 drives the connecting shaft 23 to rotate, thereby controlling the L-shaped plate 14 connected to the connecting shaft 23 to rotate with the connecting shaft 23 as the rotation axis.

[0049] Furthermore, the axial drive mechanism includes a rotatable and retractable hydraulic rod 24, the lower end of the hydraulic rod 24 is rotatably connected to the upper end of the L-shaped plate 14, the upper end of the hydraulic rod 24 is rotatably connected to the connecting shaft 23, the lower end of the connecting shaft 23 is rotatably connected to the middle position in the vertical direction of the side wall of the straight plate 14-1, the rotatable direction of the connecting shaft 23 relative to the straight plate 14-1 is perpendicular to the side wall of the straight plate 14-1, and a hydraulic pump 25 is fixedly connected to the inner wall of the U-shaped steel 21. The hydraulic pump 25 is connected to the hydraulic rod 24 through an external pipeline, and the hydraulic pump 25 is used to drive the hydraulic rod 24 to retract and retract.

[0050] The hydraulic pump 25 drives the hydraulic rod 24 to extend and retract, causing the upper end of the L-shaped plate 14 to move away from or closer to the connecting shaft 23, thereby causing the L-shaped plate 14 to rotate about a vertical line at the lower end of the connecting shaft 23 (the vertical line is parallel to the side wall of the L-shaped plate 14);

[0051] During the soil covering process, the straight plate 14-1 is first controlled to rotate by the rotating mechanism so that the straight plate 14-1 forms a certain angle A relative to the radial direction of the incomplete gear ring 2 (the end of the straight plate 14-1 connected to the seesaw 14-2 is tilted in the direction of the seesaw 14-2 tilting), and then the radial driving mechanism controls the straight plate 14-1 to be pushed into the soil accumulated around the foundation pit (hereinafter referred to as the soil pile) along the radial direction of the incomplete gear ring 2. It should be noted that the seesaw 14-2 remains outside the soil pile. During this process, part of the soil in the soil pile is pushed into the foundation pit, and then the motor 12 drives the incomplete gear ring 2 to rotate (because the incomplete gear ring 2 is not a complete gear ring, so when the motor 12 drives it to rotate, the incomplete gear ring 2 The gap will pass through motor 12, causing the incomplete gear ring 2 and the motor 12 to disengage, and at this time, the incomplete gear ring 2 can be driven to continue rotating by another motor 12; wherein the distance between the two motors 12 is greater than the distance between the two ends of the incomplete gear ring 2, thereby ensuring that the gap of the incomplete gear ring 2 can only coincide with one motor 12 at the same time), thereby driving the straight plate 14-1 to rotate around the foundation pit, and the rotation direction of the straight plate 14-1 is the tilting direction of the rocker plate 14-2. Furthermore, since the straight plate 14-1 has a certain angle A relative to the radial direction of the incomplete gear ring 2, during the movement of the straight plate 14-1, it will push the soil into the foundation pit along the radial direction of the incomplete gear ring 2. The force causes the soil in the soil pile to be continuously pushed into the foundation pit, and the presence of the seesaw 14-2 prevents the soil from separating from the straight plate 14-1 at the end where the seesaw 14-2 is located under mutual squeezing, resulting in some soil being left behind; then, when the soil on the side of the straight plate 14-1 is basically pushed into the foundation pit, the straight plate 14-1 is controlled by the rotation mechanism to rotate until it is radially perpendicular to the incomplete gear ring 2 (it should be noted that the side of the straight plate 14-1 with the soil piled up is facing the foundation pit), and then the straight plate 14-1 is moved toward the foundation pit by the radial drive mechanism to completely push the remaining soil into the foundation pit; then, the straight plate 14-1 is controlled to tilt by the axial drive mechanism, and at the same time, the straight plate 14-1 is controlled to move toward the foundation pit by the radial drive mechanism. The straight plate 14-1 is made to press the soil on the foundation pit in an inclined state so that the soil is squeezed downward. At the same time, the motor 12 drives the straight plate 14-1 to rotate in the reverse direction so that the straight plate 14-1 cooperates with the seesaw 14-2 to squeeze the soil downward in a circular manner. In this process, the straight plate 14-1 is controlled by the axial drive mechanism to gradually increase the degree of inclination so that the soil on the foundation pit is gradually compacted. In this way, through the scraping and pressing method, the soil in the foundation pit is more evenly distributed during the compaction process (since the position with less soil distribution is more easily pressed into the soil than the position with more soil distribution, the position with more soil distribution can be pushed to the position with less soil distribution by scraping), and the compaction degree is more uniform.
