Description

Technical Field

[0001] This invention relates to the field of tree transplanting technology, and more specifically to a transplanting device for planting trees in sandy areas. Background Technology

[0002] A tree transplanting device is an agricultural instrument used for transplanting saplings. It can dig up trees that are not planted in their correct locations for replanting, enabling the transplantation of trees in sandy areas and facilitating the use of workers. Mulberry trees are deciduous trees, 2-6 zhang (approximately 6.6-9 meters) tall, with a taproot system. They have strong sprouting ability, grow quickly, prefer sunlight, have moderate branch density, are drought-resistant and cold-resistant, and are also relatively tolerant of temperature and humidity, as well as alkaline conditions. Therefore, mulberry trees are excellent for soil and water conservation and sand fixation, making them a preferred plant for afforestation in sandy areas.

[0003] When transplanting mulberry trees, to improve the survival rate of the seedlings, it is usually advisable to transplant them with soil attached. Currently, the small-scale transplanting equipment for mulberry seedlings with soil attached on the market typically uses a cylindrical structure with openings at the top and bottom to complete the transplanting. In use, the cylinder is inserted into the ground, a pit is dug for planting the seedling, and then the seedling and surrounding soil are dug out through the cylinder and transplanted into the pre-dug pit. However, sandy soil is loose, and during the drilling process, the sand flows rapidly down the edge of the pit under gravity. Furthermore, a large amount of soil falls as the cylinder moves upwards, affecting the transplanted seedling. Therefore, current plant transplanting machines on the market are not suitable for transplanting trees in sandy areas. Summary of the Invention

[0021] Furthermore, in the description of this invention, "a plurality of" refers to two or more. The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0022] Example 1 This invention provides a transplanting device for planting trees in sandy areas, such as... Figure 1As shown, it includes: a cylinder 1, a supporting structure 2, and a driving structure 3. The cylinder 1 is vertically arranged, and the diameter of the top end of the cylinder 1 is larger than the diameter of the bottom end of the cylinder 1, that is, the cylinder 1 is inverted conical. The cylinder 1 has helical teeth 11 around its circumference to facilitate downward drilling. The cylinder 1 is used to fit over the sapling to be transplanted. In use, the cylinder 1 is fitted around the circumference of the sapling to be transplanted. The helical teeth 11 facilitate downward drilling, and the inverted conical shape of the cylinder 1 not only facilitates deep drilling, but also prevents sand and soil from falling off the hole wall under natural conditions. The supporting structure 2 includes a first support ring 21, multiple support plates 22, two semi-circular airbags 23, an inflation assembly, and a first driving assembly. The first support ring 21 is located at the bottom end of the cylinder 1. The first support ring 21 is an annular structure and has the same inner diameter as the bottom end of the cylinder 1, which is equivalent to extending a portion at the bottom end of the cylinder 1 to facilitate support for other components of the supporting structure 2. Multiple support plates 22 are arranged in a ring array on the inner side wall of the first support ring 21, and the support plates 22 are rotatably connected to the inner side wall of the first support ring 21. That is, the support plates 22 can rotate relative to the inner wall of the first support ring 21, and the rotation is in the vertical direction, allowing them to flip up and down. Two airbags 23 are arranged on the multiple support plates 22, such as... Figure 2 As shown, the straight sections of two semi-circular airbags 23 are arranged opposite each other. The airbags 23 are provided with an air outlet and an air inlet, and both are equipped with valves. By opening the air outlet, the airbags 23 can be deflated. The inflation component is connected to the air inlet and is used to inflate the two airbags 23. The first drive component is used to drive multiple support plates 22 to rotate. The drive structure 3 has an output end, which is connected to the cylinder 1. The drive structure 3 is used to drive the cylinder 1 to rotate, and the cylinder 1 moves up and down while rotating, which facilitates drilling into the ground. This device firstly utilizes an inverted conical cylinder 1 with spiral teeth 11 circumferentially arranged to facilitate deep drilling. The conical shape of the cylinder 1 also helps to keep the sand on the hole wall in a natural state, preventing it from falling and causing large amounts of sand to flow rapidly down the hole wall and affect the transplanted seedlings. The cylinder 1 is driven to rotate and drill downwards via a drive structure 3. Secondly, a support structure 2 is also provided. When it is necessary to lift the seedling upwards, multiple support plates 22 can be rotated to a horizontal position via a first drive component. Then, an inflation component inflates two air bladders 23, allowing them to support the bottom of the seedling. This protects the seedling during transplantation and prevents large amounts of sand from falling and affecting it. This device is designed for transplanting trees in sandy areas and effectively prevents large amounts of sand from falling and affecting the transplanted seedlings.

[0023] like Figure 2As shown, adjacent support plates 22 are further connected by connectors 24. The output of the first drive assembly only needs to be connected to one connector 24 to drive multiple support plates 22 to rotate. In this embodiment, the connector 24 includes a fixed shaft 241 and an elastic rope 242. Two fixed shafts 241 are respectively disposed on the sidewalls of two adjacent support plates 22, facing each other and aligned with the positions of the two support plates 22. The output of the first drive assembly is connected to one of the fixed shafts 241 to drive multiple support plates 22 to rotate synchronously. The two ends of the elastic rope 242 are respectively fixed to the ends of the two fixed shafts 241 away from the support plates 22. When multiple support plates 22 rotate, the elastic rope 242 can extend and retract accordingly, avoiding interference with the synchronous rotation of the multiple support plates 22. This embodiment, by providing connectors 24 between adjacent support plates 22, enables the first drive assembly to drive multiple support plates 22 to rotate synchronously.

[0024] This embodiment provides a specific structure of a first driving component, such as... Figure 3 As shown, the first drive assembly further includes: a first drive member 25, a first rotating shaft 26, a bushing 27, and a lever 28. The first drive member 25 is disposed on the inner side wall of the first support ring 21, and has an output end; the first rotating shaft 26 is disposed on the output end of the first drive member 25, and the first drive member 25 is used to drive the first rotating shaft 26 to rotate. The first drive member 25 is a motor, a servo motor, or other rotary drive structure. The first rotating shaft 26 is horizontally arranged, that is, the output shaft of the first drive member 25 is horizontally arranged, where horizontal refers to the axial direction relative to the cylinder 1; the bushing 27 is fitted and fixed in the circumference of the first rotating shaft 26, and can rotate synchronously with the first rotating shaft 26; one end of the lever 28 is fixed on the side wall of the bushing 27, and the other end of the lever 28 is fixed to one of the fixed shafts 241. The working principle of the first drive assembly: the first drive member 25 drives the rotating shaft 26 to rotate, synchronously driving the bushing 27 and the lever 28 on it to rotate, thereby driving multiple support plates 22 to rotate synchronously.

[0025] like Figure 3 As shown, the first driving component 25 is located above one of the support plates 22. The support plate 22 is L-shaped (consisting of a long plate and a short plate). As can be seen from the figure, when the support plate 22 rotates 90°, the end of the support plate 22 facing away from the first support ring 21 is vertically upward. When the support plate 22 rotates upward (i.e., returns to 0°), it can just cover and protect the first driving component 25. One end of the support plate 22 is rotatably connected to the inner ring sidewall of the first support ring 21. Two airbags 23 are connected to the other end of the support plate 22. Figure 3 From the middle, the airbag 23 is on one side of the short plate, which can avoid affecting the upward rotation of the support plate 22 and covering the first drive component 25.

[0026] Furthermore, the support plate 22 is connected to the inner side wall of the first support ring 21 via a limiting hinge. The limiting hinge allows the support plate 22 to rotate at an angle of 0° to 90° relative to the cylinder 1. This means the support plate 22 has two positional states: the first position is when the cylinder 1 is drilling downwards, i.e., the long plate in the support plate 22 is in a vertical state (support plate 22 is at 0°); the second position is when the airbag needs to be inflated to support the seedling, i.e., the long plate in the support plate 22 is in a horizontal state. Figure 2 , Figure 3 In the current state, drive the support plate 22 to rotate 90°.

[0027] Example 2 As a further improvement on Example 1, the cone angle of the cylinder 1 is 110°~130°, that is, the angle between the side wall of the cylinder 1 and the horizontal plane is 25°~35°. Within this angle range, the sand is supported by the inclined slope and is less likely to slide down, and the effect of not falling down is optimal.

[0028] Furthermore, the end of the spiral tooth 11 that is away from the inner wall of the cylinder 1 is a pointed tip, which facilitates downward drilling. At the same time, the spiral tooth 11 is inclined, with the pointed tip lower than the end of the spiral tooth 11 that connects to the inner wall of the cylinder 1. The angle between the spiral tooth 11 and the horizontal plane is 25°~35°. The spiral tooth 11 has a certain width. The spiral tooth 11 is also inclined at 25°~35° to further prevent sand from sliding down.

[0029] In this embodiment, the other structures are the same as in embodiment 1, except that optimizations have been made to embodiment 1.

[0030] Example 3 As a further improvement on Embodiment 1, the top end of the cylinder 1 is provided with a second support ring 12. The second support ring 12 is also an annular structure and has the same inner diameter as the top end of the cylinder 1, which is equivalent to the top end of the cylinder 1 extending upwards by a portion, such as... Figure 4As shown, this embodiment provides a specific structure of a driving structure 3, which includes: a sleeve 31, a threaded groove 32, a slider 33, and a second driving assembly. The sleeve 31 is vertically arranged and fitted around the circumference of the cylinder 1, providing support for the cylinder 1. A threaded groove 32 is formed on the inner wall of the sleeve 31, extending along its height. Two sliders 33 are symmetrically arranged on the sidewall of the second support ring 12, and are respectively fitted into the threaded groove 32, with each slider 33 slidably connected to the threaded groove 32. Lubricating oil can be applied to the threaded groove 32 to facilitate sliding. The second driving assembly has an output end connected to one of the sliders 33, and is used to drive the slider 33 to slide within the threaded groove 32. The working principle of the driving structure 3 in this embodiment is as follows: the second driving assembly drives the slider 33 to slide within the threaded groove 32, thereby causing the second support ring 12 and the cylinder 1 to rotate while simultaneously rising and falling relative to the sleeve 31, thus enabling the cylinder 1 to rotate while drilling underground. In addition, such as Figure 1 As shown, a pull rod 37 is provided at the top of the sleeve 31 to facilitate the user's grip and handling of the device, while a roller 38 is provided at the bottom of the sleeve 31 to facilitate the movement of the entire device and the transplanted seedlings.

[0031] This embodiment provides a specific structure of a second driving assembly. Further, the second driving assembly includes: a second driving member 34, a second rotating shaft 35, a gear 36, and a rack. The second driving member 34 is disposed at one end of one of the sliders 33 opposite to the second support ring 12, and has an output end. The second rotating shaft 35 is disposed at the output end of the second driving member 34, and the second driving member 34 drives the second rotating shaft 35 to rotate. The second driving member 34 is a motor, servo motor, or other rotary drive structure. The end of the second rotating shaft 35 opposite to the second driving member 34 is slidably connected within a threaded groove 32. The gear 36 is fitted and fixed circumferentially to the second rotating shaft 35, and the gear 36 is located within the threaded groove 32. The rack is disposed on the side wall of the threaded groove 32, and meshes with the gear 36. The working principle of the second drive assembly: The second drive component 34 drives the second rotating shaft 35 to rotate, so that the gear 36 on it rotates synchronously. The rack meshes with the gear 36, so when the gear 36 rotates, it moves synchronously on the rack, that is, it moves in the threaded groove 32, so that the cylinder 1 rotates and drills into the ground at the same time.

[0032] In this embodiment, the other structures are the same as in embodiment 1, except that optimizations have been made to embodiment 1.

[0033] The advantages of this invention are as follows: Firstly, the device, by setting an inverted conical cylinder and setting spiral teeth around it, not only facilitates deep drilling, but also ensures that the sand on the hole wall remains in a natural state and does not easily fall, thus preventing a large amount of sand from flowing down the hole wall and affecting the transplanted seedlings. The cylinder is driven to rotate and drill downwards by a drive structure. Secondly, a support structure is also provided. When it is necessary to lift the seedling upwards, multiple support plates can be driven to rotate to a horizontal state by the first drive component. Then, the two air bladders are inflated by the inflation component, so that the two air bladders can support the bottom of the seedling. On the one hand, it can protect the seedling during transplantation, and on the other hand, it can prevent a large amount of sand from falling and affecting the transplanted seedlings.

[0034] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
