Description

Technical Field

[0001] The invention belongs to the field of planting flower pots, and particularly relates to a bougainvillea root shaping device and a use method. Background Art

[0002] Bougainvillea is a woody plant with thick stems and drooping branches that are glabrous or sparsely pubescent. Its leaves are papery, ovate or ovate-lanceolate, and its bracts are leaf-like and purple or magenta. It is a woody plant widely planted in tropical and subtropical regions and has high ornamental and economic value.

[0003] In order to improve the ornamental value of Bougainvillea and fully display the ornamental value of the root system, the existing Bougainvillea is usually subjected to root lifting and shaping treatment when it is planted. Root lifting and shaping is a key technique to show the beauty of the root system of bonsai. However, in the existing technology, the root system of Bougainvillea is wrapped in a plastic pot. When the root lifting and planting is carried out, the plastic pot that wraps the root system of Bougainvillea needs to be cut, which is costly and wasteful.

[0004] This application proposes a device and method for shaping the root of Bougainvillea to improve the above-mentioned defects. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a bougainvillea root lifting and shaping device and a use method that can improve the root lifting and shaping function of the bougainvillea root system.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A bougainvillea root shaping device and a method of use, the structure of which includes a flower pot, a bottomless basin and a bracket, the bottomless basin being movably mounted on the flower pot, the bracket being mounted on the annular side wall of the flower pot, and the bracket being capable of supporting the bottomless basin.

[0008] In a specific possible implementation scheme, the bottomless basin is assembled by a plurality of expansion rings, which are connected and installed by support rods, and the bottom of the bottommost expansion ring is fixed to the flower pot by a pin through the support rod.

[0009] In a specific feasible implementation scheme, the expansion ring includes an outer expansion plate, a connecting plate, an inner expansion plate, a strap and a rotating shaft. There are several outer expansion plates in a circular array, and both ends of several of the outer expansion plates are rotatably matched with connecting plates, and the other ends of several of the connecting plates are rotatably matched with the inner expansion plates. The rotational cooperation between several of the outer expansion plates, connecting plates and inner expansion plates is carried out through a rotating shaft, and several of the inner expansion plates can form a circle and have a strap fixed on the inside.

[0010] In a specific embodiment, the strap is made of silicone material, which has high strength, breathability and flexibility.

[0011] In a specific feasible implementation scheme, a pin slot is provided at one end of the outward expansion plate, and the pin slot can be movably connected to the pin column. The other end of the pin column is fixed to the bottom of the outward expansion plate on an adjacent set of expansion rings, so that the two adjacent sets of expansion rings can be spliced ​​adjacent to each other.

[0012] In a specific possible implementation scheme, the bracket includes a bottom ring and a multi-directional support frame, and a plurality of groups of multi-directional support frames are installed on the bottom ring, and the plurality of multi-directional support frames are arranged in a circular array around the bottom ring.

[0013] In a specific feasible implementation scheme, the bottom ring includes a trapezoidal block, a slot, and a groove. There are three trapezoidal blocks in a circular array on the outer wall of the bottom ring. A slot is provided on both sides of the three trapezoidal blocks. Three grooves are provided on the bottom ring. Several of the grooves are staggered with the trapezoidal blocks, and several of the grooves can be fixed to the multi-directional support frame.

[0014] In a specific possible implementation scheme, the multi-directional support frame consists of a multi-directional rotating member and a push rod. The outer wall of the multi-directional rotating member is fixedly engaged with the groove, and the center of the multi-directional rotating member is threadedly connected with the push rod.

[0015] In a specific possible implementation scheme, the multi-directional rotating part includes an outer shell, an inner universal seat, balls, an internal threaded hole and a limit opening. The inner universal seat is gap-fitted at the center of the outer shell, a number of balls are arranged between the inner universal seat and the outer shell, an internal threaded hole is opened at the center of the inner universal seat, and a limit opening is provided at one end of the outer shell, and the diameter of the limit opening is larger than the diameter of the internal threaded hole on the inner universal seat.

[0016] In a specific feasible implementation plan, the push rod includes an external thread, a handle, a mounting frame and a sponge roller. A handle is fixed to one end of the push rod, and an external thread that can be threadedly engaged with the internal threaded hole is provided on the push rod. A mounting frame is installed on the other end of the push rod, and several sponge rollers are rotatably engaged on the mounting frame.

[0017] In a specific feasible implementation scheme, the flower pot includes a slide groove, a convex ball, a bottom plate, a positioning hole, a constraint frame and holes. Several slide grooves are opened on the top of the side wall of the flower pot, and convex balls are fixed on both sides of several of the slide grooves. The convex balls are movably engaged with the slots. A bottom plate is fixed in the flower pot, and several positioning holes corresponding to the support rods are opened on the top of the bottom plate. The bottom of the bottom plate is connected to a constraint frame, and several holes are arrayed on the side wall of the constraint frame.

[0018] According to the technical solution proposed above, the device and method for shaping the roots of bougainvillea of ​​the present invention have the following beneficial effects:

[0019] (1) The present invention adds a bottomless pot to the planting pot of bougainvillea, and assembles the bottomless pot through a plurality of spliced ​​expansion rings. The expansion rings can be stacked according to the required root lifting height of the bougainvillea root system, so that the roots of different heights can be lifted, thereby increasing the variability and adaptability of the root lifting shape.

[0020] (2) The present invention sets the expansion ring as a telescopic expansion structure. By applying an outward pulling force to the inner expansion plate, the inner expansion plate can be driven to expand outward. By means of the connecting plates at both ends of the inner expansion plate, the outer expansion plate can be driven to expand outward following the inner expansion plate, so that the diameter of the expansion ring changes. This makes it easier for the expansion ring to be applicable to the root lifting work of bougainvillea with different specifications, thereby improving the root lifting efficiency of bougainvillea. There is no need to prepare multiple bottomless pots to carry out root lifting and shaping of bougainvillea.

[0021] (3) When the expansion ring of the present invention is opened to its maximum diameter, the diameter will be larger than the diameter of the bougainvillea root system, so that the expansion ring can be removed from the bougainvillea to complete the root lifting shape, avoiding the problem of traditional root lifting through a plastic pot and then having to cut the plastic pot before it can be removed, saving costs and improving efficiency.

[0022] (4) The present invention adds a bracket to the flower pot, and the handle drives the push rod to rotate on the internal threaded hole, which can adjust the contact force and distance between the push rod and the bottomless pot, so that the push rod can support bottomless pots of different diameters. By turning the push rod, the inner universal seat is driven to rotate on the outer shell, and the support fulcrum between the push rod and the bottomless pot is adjusted, so that the bottomless pot can be supported in different positions according to needs, which can prevent the bottomless pot from being offset and tilted when the roots are lifted, thereby ensuring the quality of the root lifting shape.

[0023] (5) The present invention adds a constraint frame to the flower pot, and places the constraint frame in the center of the flower pot where the root system needs to be restricted from growing downward. The holes on the constraint frame allow the capillary roots of the bougainvillea root system to pass through and absorb nutrients and moisture from the soil inside the flower pot. However, the constraint frame can physically block the main root from growing deep outward, forcing the root system to develop towards the preset lifting area, thereby reducing ineffective root growth from the root, concentrating energy on the shaping part, and improving the efficiency of root lifting and shaping.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows:

[0037] A device for shaping bougainvillea by lifting roots and a method for use thereof, the structure of which includes a flowerpot 1, a bottomless basin 2 and a bracket 3. The flowerpot 1 can shallowly plant the roots of bougainvillea. The bottomless basin 2 is movably mounted on the flowerpot 1. The bottomless basin 2 can shape the bougainvillea by lifting roots. The bracket 3 is mounted on the annular side wall of the flowerpot 1. The bracket 3 can support the bottomless basin 2.

[0038] See also Figure 1 The flowerpot 1 and the bottomless basin 2 are used to make bougainvillea bonsai with raised roots, and a film greenhouse with functions such as shading, moisturizing, and temperature control should be selected. The first thing to do when making the root-raised shape of bougainvillea is to carry out cuttings. When cutting bougainvillea, choose branches that are thick at the top and thin at the bottom, with varying bending angles, so that the survival rate of cuttings is high.

[0039] See also Figure 1 When planting and lifting the roots of Bougainvillea, the flowerpot 1 and the bottomless pot 2 need to be filled with a sand bed inside. The planting material of the Bougainvillea sand bed is a mixture of half river sand and half Akadama soil. The mixed planting material is loose and breathable, has good drainage, is clean and sterile, and is conducive to the rooting of Bougainvillea. The prerequisite for root lifting bonsai is to first ensure that the Bougainvillea has a strong root system.

[0040] See also Figure 1-Figure 2 The bottomless basin 2 is assembled by a plurality of expansion rings 21, and the expansion rings 21 are connected and installed by support rods 22. The bottom of the bottommost expansion ring 21 is bolted to the flower pot 1 through the support rod 22.

[0041] See also Figure 3-Figure 4 The expansion ring 21 includes an outer expansion plate 211, a connecting plate 212, an inner expansion plate 213, a strap 214 and a rotating shaft 215. There are several outer expansion plates 211 in a ring array. Both ends of several outer expansion plates 211 are rotatably matched with connecting plates 212, and the other ends of several connecting plates 212 are rotatably matched with inner expansion plates 213. The rotational cooperation between several outer expansion plates 211, connecting plates 212 and inner expansion plates 213 is rotationally matched through the rotating shaft 215. Several inner expansion plates 213 can form a circle and a strap 214 is fixed on the inside.

[0042] See also Figure 3 The strap 214 is made of silicone material and has high strength, breathability and flexibility. When the expansion ring 21 expands outward, the strap 214 can elastically expand and contract as the inner expansion plate 213 expands outward.

[0043] See also Figure 4One end of the outward expansion plate 211 is provided with a pin slot 216, and the pin slot 216 can be movably connected to the pin column, and the other end of the pin column is fixed to the bottom of the outward expansion plate 211 on an adjacent set of expansion rings 21, so that two adjacent sets of expansion rings 21 can be spliced ​​adjacent to each other, and so on. The number of expansion rings 21 can be superimposed according to the required root lifting height of the bougainvillea root system, so that the roots of different heights can be lifted.

[0044] See also Figure 5 By applying outward pulling force to the inner expansion plate 213, the inner expansion plate 213 can be driven to expand outward, and with the help of the connecting plates 212 connected to both ends of the inner expansion plate 213, the outer expansion plate 211 connected to the connecting plates 212 can be driven to expand outward synchronously with the inner expansion plate 213, so that the diameter of the expansion ring 21 changes and expands outward, so that the expansion ring 21 can be suitable for the root lifting work of bougainvillea roots of different specifications, and when the expansion ring 21 is opened to the maximum diameter, the diameter will be larger than the diameter of the bougainvillea root system, so that the expansion ring 21 can be removed from the bougainvillea.

[0045] Example 2: Please refer to Figure 6-Figure 9 , the specific embodiments of the present invention are as follows:

[0046] See also Figure 6 The bracket 3 includes a bottom ring 31 and a multi-directional support frame 32. The bottom ring 31 is movably connected to the flower pot 1 and can be removed from the flower pot 1 when not in use. Several groups of multi-directional support frames 32 are installed on the bottom ring 31. Several multi-directional support frames 32 are arranged in a circular array around the bottom ring 31. With the help of the coordinated support effect of the multi-directional support frames 32, the bottomless basin 2 can be supported.

[0047] See also Figure 7 The bottom ring 31 includes a trapezoidal block 311, a slot 312, and a groove 313. There are three trapezoidal blocks 311 in a circular array on the outer wall of the bottom ring 31. The three trapezoidal blocks 311 are provided with a slot 312 on both sides. Three grooves 313 are provided on the bottom ring 31. Several of the grooves 313 are staggered with the trapezoidal blocks 311, and several of the grooves 313 can be fixed to the multi-directional support frame 32 to install the multi-directional support frame 32.

[0048] See also Figure 7 The multi-directional support frame 32 is composed of a multi-directional rotating member 321 and a push rod 322. The outer wall of the multi-directional rotating member 321 is fixedly engaged with the groove 313, and the center of the multi-directional rotating member 321 is threadedly connected with the push rod 322.

[0049] See also Figure 8The multi-directional rotating member 321 includes an outer shell 41, an inner universal seat 42, balls 43, an internal threaded hole 44 and a limiting opening 45. The inner universal seat 42 is gap-fitted at the center of the outer shell 41. A plurality of balls 43 are provided between the inner universal seat 42 and the outer shell 41. The inner universal seats 42 on both sides are rotatably fitted with the outer shell 41 through the balls 43, so that the inner universal seat 42 can rotate on the outer shell 41. An internal threaded hole 44 is opened at the center of the inner universal seat 42. A limiting opening 45 is provided at one end of the outer shell 41. The diameter of the limiting opening 45 is larger than the diameter of the internal threaded hole 44 on the inner universal seat 42.

[0050] See also Figure 8 The supporting rod 322 includes an external thread 51, a handle 52, a mounting bracket 53 and a sponge roller 54. One end of the supporting rod 322 is fixed with a handle 52 that can drive the supporting rod 322 to rotate. The supporting rod 322 is provided with an external thread 51 that can be threadedly engaged with the internal threaded hole 44. The other end of the supporting rod 322 is installed with a mounting bracket 53. The mounting bracket 53 is rotated by the main shaft and is equipped with several sponge rollers 54. The sponge rollers 54 can contact the outer wall of the bottomless basin 2 to fix the position of the bottomless basin 2, and with the help of the flexible material of the sponge, it can make contact with the bottomless basin 2 at multiple angles.

[0051] See also Figure 7-Figure 8 By turning several knobs 52 to drive the supporting rod 322 to rotate on the internal threaded hole 44, the contact force and distance between the supporting rod 322 and the bottomless basin 2 can be adjusted, so that the supporting rod 322 can support the bottomless basin 2 of different diameters, and by adjusting the angle between the inner universal seat 42 and the outer shell 41 by toggling the supporting rod 322, the support fulcrum of the supporting rod 322 and the bottomless basin 2 can be adjusted, so that the bottomless basin 2 can be supported in different positions as needed.

[0052] See also Figure 9 The flower pot 1 includes a slide 11, a convex ball 12, a bottom plate 13, a positioning hole 14, a constraint frame 15 and a hole 16. A plurality of slides 11 are provided on the top of the side wall of the flower pot 1. Convex balls 12 are fixed on both sides of the slides 11. The convex balls 12 are movably engaged with the card slots 312 to install the bottom ring 31 on the flower pot 1. A bottom plate 13 is fixed in the flower pot 1. A plurality of positioning holes 14 corresponding to the support rods 22 are provided on the top of the bottom plate 13. The positioning holes 14 are movably engaged with the support rods 22 and can facilitate the rapid installation and positioning of the bottomless basin 2. The bottom of the bottom plate 13 is connected to a constraint frame 15, and a plurality of holes 16 are arrayed on the side walls of the constraint frame 15.

[0053] See also Figure 9The constraint frame 15 can be placed in the area in the center of the flowerpot 1 where the root system needs to be restricted from growing downward. The holes 16 thereon can allow the capillary roots of the bougainvillea root system to pass through and absorb nutrients and moisture from the soil inside the flowerpot 1. However, the constraint frame 15 can physically block the main root from going deep outward, forcing the root system to develop towards the preset pulling area, which can reduce ineffective root growth from the root and concentrate energy on the shaping part.

[0054] See also Figure 9 The flowerpot 1 can be used to plant bougainvillea after it is removed from the pot. After the bougainvillea is removed from the pot, part of the root system should be trimmed, retaining 3 to 5 thick vertical roots, and all other horizontal roots and other roots should be cut off, especially the branches on the main trunk should be trimmed accordingly, the overly long branches should be shortened accordingly, and all useless branches should be cut off to reduce nutrient consumption and concentrate nutrient supply on the retained branches.

[0055] Based on the above embodiment, a method for using a bougainvillea root shaping device is as follows:

[0056] S1. First, plant the bougainvillea by cuttings. When cutting, choose branches that are thick at the top and thin at the bottom, with varying bending angles. Use two-year-old branches, which have a high survival rate. Prune the branches to a height of 15 cm and a thickness of 1 to 2 cm.

[0057] S2. Half a year after the cuttings are successful, apply organic fertilizer to promote the growth of Bougainvillea and supplement the three elements of "nitrogen, phosphorus and potassium". "Phosphorus and potassium" promote the growth of the root system of Bougainvillea. Two years after the cuttings are successful, when the root system of Bougainvillea has grown thicker and more vigorous, you can repot it and cultivate the roots again. After the Bougainvillea is removed from the pot, trim some of the roots, retaining 5 thick vertical roots, and cut off all other horizontal roots and other roots;

[0058] S3, then insert the bottomless pot 2 into the corresponding positioning hole 14 on the flower pot 1 through the support rod 22 at the bottom, and then install the bottomless pot 2 on the flower pot 1, and then plant the bougainvillea with its roots retained in the flower pot 1 and the bottomless pot 2, and fill the inside of the flower pot 1 and the bottomless pot 2 with sand, and put small particles of stone in the sand. The stone can make the root system bend and bend when growing, and ensure that the roots of the bougainvillea remain in the bottomless pot 2, with only the bottom planted shallowly in the flower pot 1, and the roots of the bougainvillea are raised and shaped through the bottomless pot 2;

[0059] S4, and according to the height of the planted bougainvillea root system, increase or decrease the number of expansion rings 21 on the bottomless pot 2 to ensure that the expansion ring 21 can wrap the bougainvillea root system for planting, and water the sand in the flower pot 1 and the bottomless pot 2, watering it thoroughly so that the lower layer of sand fits tightly under the stones and the root system, and then replenish the sand again;

[0060] S5, then rotate the handle 52 to drive the lever 322 to rotate on the internal threaded hole 44, and adjust the distance between the lever 322 and the bottomless basin 2, so that the lever 322 can support the bottomless basin 2, preventing the bottomless basin 2 from tilting during the root shaping, and playing a fixing role;

[0061] S6, then by toggling the lever 322 to drive the inner universal seat 42 to rotate in the housing 41, the contact angle between the lever 322 and the bottomless basin 2 is adjusted, and the supporting fulcrum of the lever 322 and the bottomless basin 2 can be adjusted, so that the bottomless basin 2 can be supported in different positions as needed;

[0062] S7, with the help of the constraint frame 15 installed at the bottom of the flower pot 1, the area where the bougainvillea roots grow downward can be limited. The holes 16 on the constraint frame 15 allow the capillary roots of the bougainvillea roots to pass through and absorb nutrients and moisture from the soil inside the flower pot 1. However, the constraint frame 15 can physically block the main root from growing deep outward, forcing the root system to develop towards the preset lifting area, which can reduce ineffective root growth from the root and concentrate energy on the shaping part;

[0063] S8, after a period of planting, when the root shaping of the bougainvillea is completed, an outward pulling force is applied to the inner expansion plate 213 on the bottomless pot 2, driving the inner expansion plate 213 to expand outward, and with the help of the connecting plates 212 connected to the two ends of the inner expansion plate 213, driving the outer expansion plate 211 to expand outward synchronously with the inner expansion plate 213, so that the diameter of the expansion ring 21 changes and expands outward to the maximum diameter, which is larger than the diameter of the bougainvillea, so that the expansion ring 21 can be removed from the bougainvillea;

[0064] S9, after half a year of maintenance, the several expansion rings 21 on the bottomless pot 2 are removed in sequence, with an interval of one month between each removal of an expansion ring 21, and then the soil in the bottomless pot 2 is washed away with water to expose the internal root system, thereby completing the root-lifting planting of Bougainvillea.

[0066] The above is only a specific implementation method of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the protection scope of the present application.

Half a year after the cuttings are successful, apply organic fertilizer to promote the growth of Bougainvillea and supplement the three elements of "nitrogen, phosphorus and potassium". "Phosphorus and potassium" promote the growth of the root system of Bougainvillea. Two years after the cuttings are successful, when the root system of Bougainvillea has grown thick and vigorous, repot it and cultivate the roots again. After the Bougainvillea is removed from the pot, trim some of the roots, retaining 5 thick vertical roots, and cut off all other horizontal roots and other roots. S3, then the bottomless pot (2) is inserted into the positioning hole (14) on the flower pot (1) through the support rod (22) at the bottom, and the bottomless pot (2) is installed on the flower pot (1). Then, the bougainvillea with its roots retained is planted in the flower pot (1) and the bottomless pot (2), and the inside of the flower pot (1) and the bottomless pot (2) is filled with sand, and small particles of stone are placed in the sand. The stone can make the root system bend and bend when growing, ensuring that the root system of the bougainvillea remains in the bottomless pot (2), and only the bottom is shallowly planted in the flower pot (1). The root system of the bougainvillea is raised and shaped through the bottomless pot (2); S4, and according to the height of the root system of the planted bougainvillea, increase or decrease the number of expansion rings (21) on the bottomless pot (2), ensure that the expansion rings (21) can wrap the root system of the bougainvillea for planting, and water the sand in the flower pot (1) and the bottomless pot (2), watering it thoroughly so that the lower layer of sand fits tightly under the stones and the root system, and then replenish the sand; S5, then rotating the plurality of rotary handles (52), driving the support rod (322) to rotate on the internal threaded hole (44), and being able to adjust the distance between the support rod (322) and the bottomless basin (2), so that the support rod (322) can support the bottomless basin (2), preventing the bottomless basin (2) from tilting when performing root shaping, and playing a fixing role; S6, then by toggling the support rod (322), the inner universal seat (42) is driven to rotate in the housing (41), and the contact angle between the support rod (322) and the bottomless basin (2) is adjusted, and the supporting fulcrum of the support rod (322) and the bottomless basin (2) can be adjusted, so that the bottomless basin (2) can be supported at different positions according to needs; S7, with the help of the constraint frame (15) installed at the bottom of the flower pot (1), the area where the bougainvillea root system grows downward can be limited, and the holes (16) on the constraint frame allow the capillary roots of the bougainvillea root system to pass through and absorb nutrients and water from the soil inside the flower pot (1). However, the constraint frame (15) can physically block the main root from growing deep outward, forcing the root system to develop towards the preset lifting area, which can reduce the ineffective root growth from the root and concentrate energy on the shaping part; S8, after the root shaping of the bougainvillea is completed, an outward pulling force is applied to the inner expansion plate (213) on the bottomless basin (2), driving the inner expansion plate (213) to expand outward, and with the help of the connecting plates (212) connected to both ends of the inner expansion plate (213), driving the outer expansion plate (211) to expand outward synchronously with the inner expansion plate (213), so that the diameter of the expansion ring (21) changes and expands outward to a maximum diameter, which is larger than the diameter of the bougainvillea, so that the expansion ring (21) can be removed from the bougainvillea; S9, after half a year of maintenance, the several expansion rings (21) on the bottomless pot (2) are removed in sequence, with one expansion ring (21) removed one at a time, and then the soil in the bottomless pot (2) is washed away with water to expose the internal root system, thereby completing the root-lifting shaping planting of the bougainvillea.
