Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seedling transplanting, in particular to a rare and endangered plant seedling transplanting device. BACKGROUND

[0002] Tetraclinis articulata, Heliptorumum, Euphorbia milii, Cistanche tubulosa and Dendranthema indicum are the relic plants of the ancient Mediterranean Sea, which have been maintained since the Tertiary Period, more than 170 million years ago, and are the most representative ancient relic endangered rare plants. Among them, Tetraclinis articulata is known as the "living fossil" of plants and the "giant panda" in plants. In recent years, due to the intensification of climate change and human activities, the fragile ecological environment in this area has undergone many irreversible changes, the fragmentation of Tetraclinis articulata, Heliptorumum and Euphorbia milii populations in the distribution area has gradually intensified, and the habitat suitability has decreased significantly, resulting in a decrease in distribution area and population size and a decrease in ecological function. Especially the construction of Baotou-Yinchuan Railway has a certain impact on these rare and endangered plants, so the ex-situ conservation of these relic plants is often required.

[0003] In order to ensure the survival rate of seedlings during transplanting, the soil in which the roots develop needs to be transplanted together. At the same time, in order to effectively reduce unnecessary transportation costs, it is necessary to control the size of the transplanting soil ball (the soil below the seedling is referred to as the soil ball) of the transplanted seedling. The size of the soil ball is usually proportional to the size of the seedling. The existing seedling transplanting device cannot effectively control the relationship between the two. When transplanting rare seedlings in an area, it is often necessary to adjust the device multiple times or to cut the soil ball of the dug seedling. This method is time-consuming and labor-intensive, greatly reducing the efficiency of seedling transplanting. At the same time, the secondary cutting of the soil ball will cause secondary damage to the transplanted seedling to some extent.

[0004] Therefore, it is necessary to provide a rare and endangered plant seedling transplanting device to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0029] Please refer to Figs. 1-6 The application provides a rare and endangered plant seedling transplanting device 1. The rare and endangered plant seedling transplanting device is characterized by comprising:

[0030] The driving assembly 1 is provided with a caterpillar belt on the front and back sides, and a bearing plate is fixedly arranged above the driving assembly 1. An operation room 2 is fixedly arranged on the bearing plate. A mechanical arm 3 is arranged on the right side of the operation room 2. The mechanical arm 3 is fixedly assembled above the driving caterpillar belt. Fixed feet 4 are rotatably arranged on the left side of the mechanical arm 3. A digging and transplanting assembly 5 is fixedly assembled on the right side of the mechanical arm 3. The digging and transplanting assembly 5 clamps a seedling 6 in the middle.

[0031] As a preferred embodiment, the driving assembly 1 adopts a caterpillar belt driving mode, so that the device can move on the land, thereby improving the transplanting efficiency. The fixed feet 4 can stabilize the device on the ground, so that the digging and transplanting assembly 5 cannot be lifted during the digging process, thereby providing a force. The digging and transplanting assembly clamps the trunk of the target seedling during the transplanting process of the target seedling, estimates the radius of the target seedling to a certain extent, adjusts the radius according to the estimated radius, thereby ensures that the size of the dug soil ball matches the target seedling, guarantees the transplanting efficiency of the seedling, reduces the transportation cost, and to a certain extent, avoids secondary damage to the seedling, thereby improving the survival rate of the seedling.

[0032] Further, the digging and transplanting assembly 5 comprises:

[0033] The seedling clamping assembly 51 is provided with four groups, and the four groups of seedling clamping assemblies 51 are divided into an A fixed position 53, a B non-fixed position 54 and two groups of C rotating positions 55 between each other. The A fixed position 53 is arranged between the two groups of rotating positions 55. The two groups of seedling clamping assemblies 51 located on the A fixed position 53 are fixed to each other, and a fixed connecting block 52 is fixedly assembled thereon. The fixed connecting block 52 is fixedly assembled on the right side of the mechanical arm 3.

[0034] The two groups of seedling clamping assemblies 51 at the two groups of C rotating positions 55 are provided with a sliding assembly 56 therebetween.

[0035] The seedling clamping assemblies 51 on the two sides of the B non-fixed position 54 are not treated.

[0036] As a preferred embodiment, in the initial state, the four groups of seedling clamping assemblies 51 are in the contracted state, and the two groups of seedling clamping assemblies 51 whose two groups of C rotating positions 55 are not in contact with the A fixed position 53 will slide along the sliding assembly 56, so that the center position is exposed, facilitating the device to clamp and fix, and the radius of the target seedling is estimated, and the target seedling is excavated. In the implementation, the mechanical arm 3 moves the excavating and transplanting assembly 5 to the position 250px (1px=0.04cm) away from the ground, and makes the two groups of seedling clamping assemblies 2 on the A fixed position 53 tangent to the seedling, and then makes the other two groups of seedling clamping assemblies 51 slide through the sliding assembly 56 until the two groups of seedling clamping assemblies 51 belong to the two planes of the B non-fixed position coincide.

[0037] Further, the sliding assembly 56 comprises a rotating track 57 and an automatic sliding block 58, wherein the rotating track 57 is fixedly embedded on the two groups of seedling clamping assemblies 51 at the C rotating position 55, and the automatic sliding block 58 is fixedly assembled on the two groups of seedling clamping assemblies 51 at the C rotating position 55 which is not processed, and the automatic sliding block 58 on the same sliding assembly 56 is slidingly assembled on the rotating track 57;

[0038] As a preferred embodiment, the rotating track 57 contains a 120° obtuse angle section, when the automatic sliding block 58 drives the corresponding seedling clamping assembly 51 to slide to this position, it will rotate, so that the seedling clamping assembly 51 is tangent to the target seedling.

[0039] Further, the seedling clamping assembly 51 comprises:

[0040] The clamping block 511 is mirror image arranged with two groups, fixedly assembled on the fixed connection block 52 or the sliding assembly 56, and the upper end is slidingly provided with a sliding rod 512, the inner side of the sliding rod 512 is rotatably embedded with an angle adjusting hydraulic cylinder 514, and the sliding rod 512 on both sides of the angle adjusting hydraulic cylinder 514 is coaxially provided with a first extension spring 513, and the two groups of first extension springs 513 are fixedly assembled on the corresponding clamping block 511;

[0041] As a preferred embodiment, in the initial state, the angle hydraulic cylinder 514 is in the fully extended state, at this time, the included angle between the axis and the ground is the smallest, and the soil ball excavated by the excavating and transplanting assembly 5 is the shallowest.

[0042] Further, the left side of the two groups of clamping blocks 511 is slidingly provided with a rotating shaft 518, the lower digging assembly 515 is rotatably embedded on the rotating shaft 518, and the second extension spring 517 is coaxially arranged on the rotating shaft 518 at both ends of the lower digging assembly 515, and the two groups of second extension springs 517 are fixedly assembled on the corresponding clamping blocks 511;

[0043] As a preferred embodiment, the first tensile spring 513 and the second tensile spring 517 are both tensile springs, and in the initial condition without external force, the first tensile spring 513 and the second tensile spring 517 are both in the normal state (shortest), and the clamping block 511 at both ends is in the contracted state. During the sliding process of the sliding assembly 56 along its track, it will gradually contact the target seedling, and through the conduction of the target seedling, the first tensile spring 513 and the second tensile spring 517 on the four groups of seedling clamping assemblies 51 will be elongated, so that the two planes at the B non-fixed position finally coincide. After the coincidence, because of the tension of the first tensile spring 513 and the second tensile spring 517 on each group of seedling clamping assemblies 51, the clamping block 511 will always have a tendency to slide inward, and under the constraint of other seedling clamping assemblies 511, it will continuously compress the distance from the seedling, so as to fit the target seedling, and facilitate more accurate estimation of the radius thereof.

[0044] Further, the other end of the angle adjusting hydraulic cylinder 514 is rotatably assembled on the lower digging assembly 515, and the lower digging assembly 515 is fixedly assembled with the radius adjusting hydraulic cylinder 516, and the other end of the radius adjusting hydraulic cylinder 516 is rotatably assembled on the rotating shaft 518.

[0045] As a preferred embodiment, the radius of the soil ball dug by the device is the smallest when the radius adjusting hydraulic cylinder 516 is in the fully contracted state.

[0046] Further, the elongation of the radius adjusting hydraulic cylinder 516 is proportional to the elongation of the first tensile spring 513 and the second tensile spring 517, and is inversely proportional to the elongation of the angle adjusting hydraulic cylinder 514.

[0047] As a preferred embodiment, the relationship between the radius adjusting hydraulic cylinder 516, the first tensile spring 513 and the second tensile spring 517, the angle adjusting hydraulic cylinder 514 and the seedling radius should be such that the diameter D of the soil ball satisfies the formula: D = J + K(d-3), J is a constant 24, d is the diameter of the trunk at the ground 250px, and K is a constant (its size is related to the type of tree, for example, K = 4 for evergreen trees, and K = 5 for deciduous trees).

[0048] Further, the lower digging assembly 515 comprises:

[0049] The rotating connecting block 5151 is rotatably embedded in the rotating shaft 518, and the left side is fixedly assembled with the driving sliding assembly 5152, the driving sliding assembly 5152 is slidably assembled on the lower digging knife 5154 provided with a sliding groove 5153, and the driving sliding assembly 5152 is provided with a mud cleaning brush.

[0050] As a preferred embodiment, under initial conditions, the undercutting knife 5154 is in its upper limit position, wherein the mud brush can clean the mud clogged in the sliding groove 5153 during the lifting process after the undercutting of the undercutting knife 5154, preventing the mud from hindering the operation of the driving sliding assembly 5152 during secondary use, thereby reducing the transplanting efficiency of the device. The undercutting knife 5154 is arc-shaped below, so that a part is left below during the undercutting process. The part is disconnected by external force or other devices when the device moves the seedling, so that the part below presents a broken or flat shape, thereby facilitating transportation.

[0051] Further, the rotating connecting block 5151 is provided with a radius adjusting groove 5155;

[0052] As a preferred embodiment, the radius adjusting groove 5155 is provided, so that the relative position of the undercutting assembly 515 and the corresponding seedling holding assembly 51 is variable, so that the distance from the central axis of the seedling during the transplanting process is variable, so that the radius of the soil ball can change with the target seedling, and during the process of initial conditions→contact with the target seedling and completion of transplanting→return to initial conditions, the adjacent undercutting knife 5154 can be prevented from interfering during the moving process by the elongation of the radius adjusting hydraulic cylinder 516.

[0053] In specific implementation, the following steps are included: according to the type of the target seedling, the relationship between the radius adjusting hydraulic cylinder 516, the first tensile spring 513 and the second tensile spring 517, the angle adjusting hydraulic cylinder 514 and the radius of the seedling is set, then the device is moved to the specified position by the driving assembly 1, and the device is stabilized on the ground by the fixing foot 4, the digging and transplanting assembly 5 is moved to the trunk 250px (1 cm, 1px=0.04 cm) from the ground by the mechanical arm 3, and the two groups of seedling clamping assemblies 2 on the A fixed position 53 are tangent to the seedling, then the other two groups of seedling clamping assemblies 51 are slid by the sliding assembly 56 until the two planes of the two groups of seedling clamping assemblies 51 belonging to the B non-fixed position coincide, then the radius adjusting hydraulic cylinder 516 and the radius adjusting hydraulic cylinder 516 will be stretched to a certain extent according to the set radius, after the adjustment is completed, the undercutting assembly 515 drives the undercutting knife 5154 to undercut until it reaches the limit position, and each assembly returns to the initial position to complete the work, or the target seedling and the soil ball are directly lifted and moved to the specified position, and each assembly returns to the initial position to complete the work.

[0054] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto.
