[0003] The existing bougainvillea wall cutting device is usually a simple combination of a planting box and a climbing rack. The wall cutting cultivation of bougainvillea mainly relies on manual labor, and requires manual regular watering.

[0041] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] like Figure 1As shown, an embodiment of the present invention proposes a bougainvillea wall cutting device and planting method, including a water tank 101 and a cultivation box 102 fixedly connected above the water tank 101 and a stand 103 symmetrically fixedly connected to the surface of the water tank 101, a horizontal frame 104 is fixedly connected between the two stands 103, a water volume regulating component is arranged inside the water tank 101, a ventilation component and a dripping component are respectively arranged inside the two stands 103, and a protective component is arranged above the cultivation box 102.

[0043] In this embodiment, the moisture of the substrate during the cultivation of bougainvillea wall cuttings can be adjusted by the water volume regulating component, so that the moisture of the substrate is suitable for the growth of bougainvillea at the current stage, and as the bougainvillea climbs the wall, the part of the bougainvillea close to the wall can be ventilated by the ventilation component, so that the side of the bougainvillea close to the wall and the part located in the corner are prevented from being ventilated, thereby preventing the growth of mold and insect pests;

[0044] By using the dripping component, the water regulating component supplements the substrate humidity regulation, so that the part of the substrate inside the cultivation box 102 away from the water tank 101 can be supplemented with a certain amount of water, thereby improving the uniformity of the substrate humidity inside the cultivation box 102. At the same time, in dry weather or when it is inconvenient to water and irrigate for a long time, water can be dripped on the surface of the bougainvillea to improve the water supplement of the bougainvillea and prevent the local drying and wilting of the bougainvillea. At the same time, intermittent dripping can clean the dust on the surface of the branches and leaves of the bougainvillea and prevent the substrate humidity inside the cultivation box 102 from being too high, thereby affecting the regulation of the substrate humidity by the water regulating component;

[0045] Through the use of protective components, the bougainvillea can be prevented from being excessively washed by rain on rainy days. At the same time, the protective components can also be used to control the time that the bougainvillea is exposed to sunlight and avoid exposure to strong sunlight. The bougainvillea can also be covered and protected in strong wind weather, thereby reducing the impact of harsh environments during the growth process of the bougainvillea through wall cutting cultivation.

[0046] It should be noted that: a through hole is opened on the surface of the water tank 101 near the incubation box 102, which is convenient for adding water to the inside of the water tank 101 and for air flow to enter the inside of the water tank 101. The stand 103 is fixedly connected to the water tank 101. At the same time, a connecting groove is opened at the connection between the stand 103 and the water tank 101 to connect the stand 103 with the inside of the water tank 101, so that air can enter the inside of the stand 103 from the outside through the water tank 101. In this embodiment, the left stand 103 can also be disconnected from the inside of the water tank 101 to enhance the air flow speed of the small hole at the bottom of the climbing tube 233. This device can be used in conjunction with a soil moisture meter to intuitively observe the humidity of the soil matrix.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the water volume regulating component includes: an absorbent blanket 201 slidably connected to the inside of the incubator 102, a plurality of hinges 205 are arranged inside the water tank 101, and an absorbent block 206 is fixedly connected to the surface of the hinge 205. One of the leaves of the hinge 205 is fixedly connected to the inner bottom surface of the water tank 101, and the other leaf of the hinge 205 is a movable leaf. By adjusting the angle of the movable leaf, the amount of contact between the absorbent block 206 on the surface of the hinge 205 and the absorbent blanket 201 is changed, thereby changing the efficiency of the absorbent blanket 201 in drawing water from the inside of the water tank 101.

[0048] A first gear 207 is fixedly connected to the end of the rotating shaft of the movable leaf of the hinge 205, and a T-shaped limit block 211 is fixedly connected to the inside of the water tank 101. A rack 212 is slidably connected to the surface of the T-shaped limit block 211. The first gear 207 is meshed with the rack 212, and the end of the rack 212 is fixedly connected to a connecting plate 209. A first screw 210 is threadedly connected to a first threaded hole opened on the surface of the connecting plate 209. The first screw 210 is rotatably connected to a reserved hole opened on the surface of the water tank 101 through a second bearing. The angles of the movable leaves between any adjacent hinges 205 are the same.

[0049] In this embodiment, different substrate humidity is required for different growth stages and different growth environments of Bougainvillea wall cutting cultivation. According to the required soil substrate humidity, the first screw 210 is rotated so that the connecting plate 209 on the surface of the first screw 210 drives the rack 212 to slide on the surface of the T-shaped limit block 211. This process causes the first gear 207 to rotate a certain angle. The rotation of the first gear 207 causes the movable leaf of the hinge 205 to drive the water absorption block 206 to rotate, thereby adjusting the number of water absorption blocks 206 in contact with the bottom surface of the water absorption blanket 201. Water is absorbed by the part of the water absorption block 206 immersed in the water of the water tank 101 using the water absorption characteristics of the water absorption block 206 itself, and the water inside the water tank 101 is transferred to the water absorption blanket 201 through the part of the water absorption block 206 in contact with the bottom surface of the water absorption blanket 201, and the water is transferred to the soil matrix through the water absorption strips 202 evenly arranged in the cultivation box 102 in contact with the soil matrix, thereby maintaining the humidity of the soil matrix.

[0050] On rainy days or when external water enters the cultivation box 102 from the top, the water content of the soil matrix inside the cultivation box 102 increases, and part of the water flows out from the drainage grooves 204 evenly opened on the side walls of the cultivation box 102, and part of the water flows into the water tank 101 under the action of gravity through the water absorption strips 202 and the water absorption blanket 201. At this time, the water absorption strips 202 and the water absorption blanket 201 transport the water in the cultivation box 102 to the inside of the water tank 101 to prevent water accumulation inside the cultivation box 102.

[0051] It should be noted that: a plurality of strip grooves are provided on the inner bottom surface of the incubator 102, and the absorbent blanket 201 is laid inside the incubator 102. Under the pressure of the soil matrix filled inside the incubator 102, it protrudes toward the bottom of the water tank 101, so that the absorbent block 206 contacts the bottom surface of the absorbent blanket 201. In the present embodiment, the absorbent blanket 201, the absorbent strip 202 and the absorbent block 206 are all made of felt, and the water absorption of the felt is greater than that of the soil matrix, so that the humidity of the soil matrix can be adjusted by adjusting the contact amount between the absorbent block 206 and the absorbent blanket 201; a corresponding T-shaped groove is provided on the surface of the rack 212, so that it can slide in cooperation with the T-shaped limit block 211.

[0052] like Figure 3 , Fig.11 and Fig.12 As shown, the ventilation assembly includes: a first cup wheel 234 arranged on the surface of the left side frame 103, a plurality of fan blades 232 are arranged inside the left side frame 103, a plurality of climbing tubes 233 are equidistantly arranged on the surface of the left side frame 103, and small holes are evenly opened at the bottom of the climbing tubes 233. The first cup wheel 234 is driven to rotate by natural wind, so that the air flow flows in the air duct formed between the climbing tubes 233 and the left side frame 103.

[0053] A cross fixing frame 241 is fixedly connected in a first circular groove opened on the upper surface of the left side frame 103, the rotating shaft of the first cup wheel 234 is rotatably connected in a second circular groove starting from the surface of the cross fixing frame 241 through a third bearing, the rotating shaft of the first cup wheel 234 extends to the bottom of the left side frame 103, the fan blades 232 are equidistantly fixedly connected to the surface of the rotating shaft of the first cup wheel 234, the climbing tube 233 is fixedly connected in the third circular groove opened on the surface of the left side frame 103, and the end of the climbing tube 233 away from the left side frame 103 is fixedly connected to the right side frame 103.

[0054] In this embodiment, the height of the first cup wheel 234 is higher than the wall so as to be blown by natural wind. When natural wind blows on the first cup wheel 234, the first cup wheel 234 rotates and drives the fan blades 232 on the surface of its rotating shaft to rotate. The rotation of the fan blades 232 causes the airflow to enter or be discharged from the interior of the left upright frame 103 through the gap between the cross fixing frame 241 and the second circular groove opened on the surface of the left upright frame 103. At this time, the pressure inside the upright frame 103 increases or decreases, which will cause the climbing tube 233 to blow out or absorb airflow through the small hole opened at its bottom toward the side of the bougainvillea close to the wall, thereby allowing airflow to circulate on the side of the bougainvillea close to the wall to reduce the occurrence of mold and insect diseases. At the same time, the rotation of the first cup wheel 234 also increases the exchange rate between the water tank 101 and the external airflow, thereby adjusting the evaporation efficiency of the absorbent blanket 201 to cooperate with the water volume regulating component to adjust the humidity of the soil matrix inside the incubator 102.

[0056] The rotating shaft of the second cup wheel 235 is rotatably connected to the fourth circular groove provided on the surface of the right side frame 103 through the fourth bearing. The surface of the rotating shaft of the second cup wheel 235 is fixedly connected to a connecting column 227. The surface of the connecting column 227 is fixedly connected to a first bevel gear 228. The driving wheel 222 and the driven wheel 223 are rotatably connected to the inner wall of the right side frame 103 through the fifth bearing and the sixth bearing respectively. The surface of the driving wheel 222 is fixedly connected to a second bevel gear 229. The second bevel gear 229 is meshed with the first bevel gear 228.

The end of the second screw 238 contacts the surface of the driven wheel 223.

[0057] The outer surface of the water-absorbing belt 225 is made of sponge material, which is used to absorb water and store it. The inner surface of the water-absorbing belt 225 is made of nylon mesh, which is used to reduce the deformation of the sponge during movement, and also to allow the water squeezed out of the sponge to pass through the nylon mesh and fall into the inside of the water-guiding block 224. The inner surface of the water-absorbing belt 225 is fixedly connected with equidistant protrusions for meshing with the driving wheel 222 and the driven wheel 223.

[0058] The interior of the U-shaped square tube 213 is fixedly connected with a buffer water-block 247 and a U-shaped partition plate 242, the buffer water-block 247 and the U-shaped partition plate 242 are fixedly connected, a first strip groove 246 is provided on the surface of the U-shaped partition plate 242, a buoyancy block 243 is slidably connected inside the first strip groove 246, a T-shaped magnetic rod 244 is symmetrically fixedly connected inside the U-shaped square tube 213, the buoyancy block 243 is slidably connected to the surface of the T-shaped magnetic rod 244, a magnetic ring 245 is symmetrically fixedly connected to the upper surface of the buoyancy block 243, and the two magnetic rings 245 are slidably connected to the two T-shaped magnetic rods 244 respectively.

[0059] The drip strip 240 has a U-shaped structure, and both ends of the drip strip 240 are fixedly connected to the second strip groove opened on the bottom surface of the U-shaped square tube 213, and the drip strip 240 is connected to the inside of the U-shaped square tube 213, and fine holes are evenly opened on the bottom surface of the drip strip 240.

[0060] In the embodiment of the present invention, the second cup wheel 235 arranged on the surface of the right side frame 103 rotates under the action of natural wind. When the second cup wheel 235 rotates, the first bevel gear 228 is driven to rotate through the connecting column 227, that is, the second bevel gear 229 is rotated, and the rotation of the second bevel gear 229 drives the transmission wheel 222 to rotate. The rotation of the transmission wheel 222 causes the water absorption belt 225 to be transmitted on the surfaces of the driven wheel 223 and the transmission wheel 222, so that the part of the water absorption belt 225 located at the bottom of the frame 103 absorbs the water flowing into the frame 103 from the inside of the water tank 101. The water carried by the water absorption belt 225 is transmitted to the surface of the driving wheel 222, and is squeezed by the water squeezing block 226 as the driving wheel 222 rotates. The water squeezed by the water absorption belt 225 falls into the interior of the water guide block 224. During this process, the water squeezing block 226 slides along the annular groove 230 and rotates relative to the connecting column 227, and enters the interior of the U-shaped square tube 213 through the guidance of the water guide block 224. The water entering the interior of the U-shaped square tube 213 first accumulates in the area surrounded by the buffer water isolation block 247 and the U-shaped square tube 213. When the accumulated water overflows the buffer water isolation block 247, the water will be sucked out of the water absorption belt 225. After that, it accumulates on the upper surface of the U-shaped partition plate 242 until the water on the upper surface of the U-shaped partition plate 242 causes the buoyancy block 243 to float upward through the buoyancy effect, and the magnetic ring 245 is attracted to the metal part of the T-shaped magnetic rod 244 through the magnetic attraction of the magnetic ring 245. At this time, the water on the upper surface of the U-shaped partition plate 242 flows into the lower part of the U-shaped partition plate 242 through the first strip groove 246 opened on the surface of the U-shaped partition plate 242, and drips out through the fine holes opened on the surface of the drip strip 240. The function of the buffer water block 247 is to prevent the second wind cup wheel 235 from rotating too fast, resulting in the water flowing from the water guide block 224 into the U-shaped partition plate 242. The water inside the U-shaped square tube 213 flows too fast, which causes the drip bar 240 to drip continuously. When the water on the upper surface of the U-shaped partition plate 242 gradually decreases, the gravity of the buoyancy block 243 is greater than the magnetic attraction between the magnetic ring 245 and the T-shaped magnetic rod 244. The buoyancy block 243 falls along the surface of the T-shaped magnetic rod 244 until the first strip groove 246 is blocked again. This process makes the water dripping on the surface of the bougainvillea branches and leaves more uniform, and at the same time, the part of the soil matrix away from the water tank 101 is replenished with water, thereby supplementing the regulation of the water volume regulating component on the humidity of the soil matrix, so that the moisture content of the soil matrix is ​​evenly distributed.

[0061] When the dripping operation is not needed, the second screw 238 on the surface of the water tank 101 is rotated so that the end of the second screw 238 squeezes the surface of the driven wheel 223. Under the action of friction, the driven wheel 223 stops rotating, so that the second bevel gear 229 on the surface of the transmission wheel 222 restricts the connection column 227 inside the first bevel gear 228 from rotating, and the second cup wheel 235 overcomes the wind force and stops rotating.

[0062] It should be noted that the T-shaped magnetic rod 244 is composed of a magnetic disc and a cylindrical rod, which is convenient for the sliding and adsorption of the magnetic ring 245; the transmission wheel 222 is composed of two circular ring plates and a circular array fixedly connected to a circular rod between the two circular ring plates, and the annular groove 230 is opened on the surface of the circular ring plate. The driven wheel 223 is composed of two circular plates and a circular array fixedly connected to a circular rod between the two circular plates, which is convenient for meshing with the equidistantly arranged protrusions on the inner surface of the water absorption belt 225 through the gap between any adjacent circular rods. The water guide block 224 is arc-shaped and one end is closed, which facilitates water to flow to the inside of the U-shaped square tube 213.

[0063] like Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the protection component includes: a cloth roll 221 and a water storage box 215 arranged above the cultivation box 102. Rainwater is collected inside the water storage box 215, so that the water storage box 215 drives the cloth roll 221 to roll and unroll under the action of gravity, thereby covering the bougainvillea in the device for protection.

[0064] Four L-shaped brackets 217 are fixedly connected to the surface of the U-shaped square tube 213, and guide wheels 219 are installed on the surfaces of the L-shaped brackets 217. A cloth roll 221 is arranged between the two guide wheels 219 close to the two vertical frames 103. A reflective material is arranged on the side of the T-shaped limit block 211 facing the climbing tube 233. The reels of the cloth roll 221 are fixedly connected to the rotating shafts of the two guide wheels 219 respectively. A water storage box 215 is arranged on the side of the U-shaped square tube 213 away from the vertical frame 103. The water storage box 215 is connected to one end of the cloth roll 221 by a plurality of ropes. A drainage hole is opened on the surface of the water storage box 215 near the bottom, and a flange 216 is fixedly connected to the surface of the U-shaped square tube 213.

[0065] The surfaces of the two upright frames 103 are respectively fixedly connected with slides 248, and the interior of the slides 248 is slidably connected with a gravity block 249. The surface of the gravity block 249 is fixedly connected with a connecting rope 220, and the surface of the connecting rope 220 passes through the guide wheel 219 close to the upright frame 103 and the guide wheel 219 far away from the upright frame 103 in sequence. The surface of the water storage box 215 is symmetrically fixedly connected with a hanging column 239, and one end of the two connecting ropes 220 away from the gravity block 249 is respectively fixedly connected to the hanging column 239. A third screw 251 is arranged in a rectangular groove opened on the surface of the slide 248, and the third screw 251 is threadedly connected to the second threaded hole opened on the surface of the corresponding gravity block 249.

[0066] In the present embodiment, on rainy days, rainwater falls into the water storage box 215 and gathers, and at the same time slowly flows out through the drainage holes on the surface of the water storage box 215. When the rainwater is heavy, the rainwater accumulated inside the water storage box 215 gradually increases until the total gravity of the water storage box 215 is greater than the total gravity of the two gravity blocks 249. At this time, the water storage box 215 will fall downward. During the falling process, the water storage box 215 drives the cloth roll 221 to unwind through the rope. In this process, the cloth roll 221 covers the U-shaped square tube 213 and extends downward at the same time, so that the bougainvillea is covered between the cloth roll and the wall, preventing rainwater from excessively scouring the branches, leaves and flowers of the bougainvillea and affecting its growth and beauty. The setting of the flange 216 can accelerate the accumulation of rainwater inside the water storage box 215. During the falling process of the water storage box 215, the water storage box 215 is connected to the wall by dragging the two hanging columns 239 on the surface. The rope 220 slides along the surfaces of the two guide wheels 219 on the same side. During the sliding process, the two guide wheels 219 located on the surface of the reel of the cloth roll 221 drive the cloth roll 221 to unwind under the action of the friction force of the connecting rope 220, and make the gravity block 249 at the end of the connecting rope 220 slide upward along the inner wall of the slide cylinder 248 until the water storage box 215 falls on the ground or the gravity block 249 moves to the set position inside the slide cylinder 248. When the rain stops, the water accumulated in the water storage box 215 is gradually discharged from the drainage hole until the total weight of the water storage box 215 is less than the total weight of the two gravity blocks 249. At this time, the water storage box 215 moves upward, and the two gravity blocks 249 move downward inside the slide cylinder 248. During this process, the connecting rope 220 slides over the surfaces of the two guide wheels 219 on the surface of the reel of the cloth roll 221, and drives the cloth roll 221 to complete the winding action.

[0067] In windy weather, the water storage box 215 can also be dragged so that the water storage box 215 drives the cloth roll 221 through the rope to complete the unwinding and the position of the water storage box 215 can be kept fixed through external fixings, such as using ropes and counterweights to fix the water storage box 215 to the ground, so that the bougainvillea can be covered and protected.

[0068] Since the sunlight required for different growth stages of Bougainvillea is different, the water storage box 215 can be dragged to a certain position to unroll a portion of the cloth roll 221, thereby providing a certain degree of shading for the Bougainvillea, thereby adjusting the lighting time of the Bougainvillea, and the friction between the third screw 251 and the surface of the slide 248 can be increased by rotating the third screw 251, so that the relative position of the gravity block 249 and the corresponding slide 248 is fixed, that is, the shading area of ​​this portion of the cloth roll is maintained.

[0069] It should be noted that the maximum cloth roll weight extended from the cloth roll 221 plus the weight of the water storage box 215 in an empty state is still less than the weight of the two gravity blocks 249 .

[0070] A method for planting bougainvillea by wall cuttings comprises the following steps:

[0071] Step 1, filling the incubator 102 with a matrix, and inserting the bougainvillea cuttings into the matrix;

[0072] Step 2: During the survival period of the bougainvillea cuttings, the rack 212 is moved inside the water tank 101 by rotating the first screw 210, and the first gears 207 are driven to rotate a certain angle, so that the absorbent block 206 on the surface of the hinge 205 contacts the absorbent blanket 201, so that the substrate inside the cultivation box 102 maintains humidity;

[0073] Step 3: During the rooting period of the bougainvillea cuttings, the contact amount between the water absorbing block 206 and the water absorbing blanket 201 is reduced by rotating the first screw 210;

[0074] Step 4: During the growth of bougainvillea climbing the wall, the fan blades 232 in the left stand 103 are driven to rotate by the first cup wheel 234, so that the climbing tube 233 blows or absorbs gas toward the part of the bougainvillea close to the wall; in heavy rain, rainwater accumulates in the water storage box 215, the total weight of the water storage box 215 increases, the water storage box 215 falls downward, and at the same time, the cloth roll 221 is unwound to cover the bougainvillea. After the water inside the water storage box 215 is emptied, the two gravity blocks 249 drag the water storage box 215 upward through the connecting rope 220. In the process of the connecting rope 220 sliding along the guide wheel 219, the guide wheels 219 at both ends of the cloth roll 221 drive the cloth roll 221 to rewind, and the water storage box 215 is manually dragged and fixed by an external fixing to shade the bougainvillea.

[0075] Step 5, when the environment is dry, natural wind drives the driving wheel 222 to rotate through the second wind cup wheel 235, so that the water absorption belt 225 carries the water inside the water tank 101 upward, and the water absorption belt 225 is squeezed by the water squeezing block 226, and the squeezed water is guided by the water guide block 224, so that the inside of the U-shaped square tube 213 accumulates water, and the accumulated water is intermittently dripped on the bougainvillea through the drip strip 240;

[0076] In a dry environment, the transmission wheel 222 is rotated by the second cup wheel 235, and the water absorption belt 225 is driven to carry the water inside the water tank 101 upward. Through the squeezing of the water squeezing block 226 and the diversion of the water guide block 224, water is accumulated inside the U-shaped square tube 213, and the accumulated water is intermittently dripped on the bougainvillea through the drip strip 240. When the dripping action stops, the second screw 238 is rotated so that the end of the second screw 238 is against the driven wheel 223, thereby stopping the water squeezing block 226 from carrying water.

[0077] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
