[0001] The invention belongs to the field of forestry, and relates to a protective device and a water supply device for afforestation, and in particular to a seedling planting protective device and an automatic water supply device. Background Art

[0002] Afforestation is an important means to prevent wind and sand, solve the desertification of land in my country, reduce soil erosion, and improve the ecological environment. Seeding afforestation, seedling afforestation, and cutting afforestation are commonly used afforestation methods. These afforestation methods require the land to have certain conditions, such as soil structure conditions, temperature and humidity conditions, etc. Since the conditions in the areas where afforestation is required are not good, the sown seeds and planted seedlings have a low survival rate due to the poor environment, which affects the afforestation effect. Therefore, carrying out seedling care and protection and improving the local living conditions of seedlings are important links to ensure the survival of seedlings. Existing tree planting protection devices and methods are mostly used in small-area environments such as landscape trees due to their high application costs, and cannot be used in afforestation projects on a large scale. Therefore, it is necessary to provide a low-cost forestry protection tool and automatic watering device for afforestation work to improve the survival rate of tree planting. Summary of the invention

[0003] In order to solve the problem of protecting seedlings, the present invention provides a seedling planting protection device, which is characterized in that: the seedling planting protection device includes a light protection cover and a protection tube; the light protection cover is a transparent plastic cover with a cap formed by a plurality of raised fan-shaped cylinders, the inner side of the light protection cover is partially covered with a reflective layer, and the plane formed by the upper edge of the reflective layer is a beveled surface with a certain inclination angle, forming a light window, and light is emitted into the light protection cover through the light window; the protection tube is a cylindrical double-layer structure formed by combining multiple pieces of hollow insulation materials with a double-layer structure, the inner side of the protection tube is set as a prismatic surface surrounded by a plurality of raised fan-shaped cylinders, and the inner surface is covered with a reflective layer.

[0004] In order to realize the seedling planting protection device described in the present invention, the following technical solution is proposed: the seedling planting protection device includes a lighting protection cover and a protection tube.

[0005] The lighting protection cover is a transparent plastic cover with a capped top surrounded by multiple raised fan-shaped cylinders. The top of the lighting protection cover is in a pointed shape to prevent dust from gathering on the top; porous ventilation holes are set on the lighting protection cover to achieve the purpose of air circulation inside and outside the lighting protection cover; the top and partial sides of the lighting protection cover remain transparent, and the other parts of the inside are covered with a layer of silver reflective layer. The plane surrounded by the upper edge of the reflective layer is a beveled surface with a certain inclination angle, and a transparent lighting window is formed on the upper part of the lighting protection cover, through which light can enter the lighting protection cover; the surface of the reflective layer is a raised fan-shaped cylinder, forming a convex mirror effect, so that the incident light is scattered, preventing the problem of the reflection surface converging the light to form a high-temperature light spot and burning the seedlings; the lower edge of the lighting protection cover is provided with inner and outer side fences, and the lighting protection cover is fixed on the top of the protective tube by the inner and outer side fences in a socketed manner.

[0006] The protective tube is a double-layer structure, which is a cylindrical structure formed by combining multiple pieces of double-layer hollow insulation materials. One side of the double-layer hollow insulation material is an upwardly protruding wavy cylinder composed of multiple fan-shaped cylinders, the surface is covered with a silver reflective layer, and docking joints are set at the left and right ends; multiple pieces of double-layer hollow insulation materials are combined together through docking joints to form a circular tubular protective tube. The appearance of the protective tube is that the outer layer is a circular thin-walled tube, and the inner layer is a prismatic thin-walled tube surrounded by multiple raised fan-shaped cylinders. The outer layer and the inner layer of the protective tube are connected together by a grating-like thin sheet to form a hollow double-layer structure. The inner surface of the protective tube is covered with a silver reflective layer, forming a convex mirror effect, which causes the incident light to scatter, preventing the reflection surface from converging the light to form a high-temperature spot and burn the seedlings.

[0007] The beneficial effects of the seedling planting protection device described in the present invention are: the lighting protection cover and the protection tube that constitute the seedling planting protection device have a simple structure, low cost, and are reusable; the protection tube adopts a double-layer insulation structure, which has the functions of resisting high temperature, cold, and wind and sand, and improves the ability of seedlings to resist high temperature and severe cold; the inner wall surface of the seedling planting protection device is a prismatic surface composed of multiple fan-shaped columns, and the surface is covered with a reflective layer. After the light is incident, it can reach the bottom after multiple reflections and scattering, providing sufficient lighting conditions for the seedlings.

[0008] In order to solve the problem of watering and maintaining seedlings, the present invention provides an automatic watering device, which is characterized in that: the automatic watering device includes a water storage cylinder circular tube, a water storage cylinder upper cover, a locking cap, a water storage cylinder lower cover, a water inlet pipe, a water outlet nozzle, a sealing gasket, a float valve, and a water absorbing material; the water storage cylinder upper cover and the water storage cylinder lower cover seal the water storage cylinder circular tube from both ends to form a cylindrical water storage cylinder; overflow holes and exhaust holes are arranged on the side of the water storage cylinder circular tube; the water inlet pipe, the water outlet nozzle, the sealing gasket, and the float valve constitute a water level controller for controlling the water level in the water storage cylinder; the water absorbing material is wrapped around the outside of the float valve, and circular through holes are evenly arranged on the water absorbing material to achieve the purpose of increasing the contact area with the air.

[0009] In order to realize the automatic water application device described in the present invention, the following technical scheme is proposed: the automatic water application device comprises a water storage cylinder circular tube, a water storage cylinder upper cover, a locking cap, a water storage cylinder lower cover, a water inlet pipe, a water outlet nozzle, a sealing gasket, a float valve, and a water absorbing material; the water storage cylinder upper cover and the water storage cylinder lower cover seal the water storage cylinder circular tube from both ends to form a cylindrical water storage cylinder; an overflow hole and an exhaust hole are arranged on the side of the water storage cylinder circular tube, and the overflow hole is below the exhaust hole; the water inlet pipe, the water outlet nozzle, the sealing gasket, and the float valve constitute a water level controller, the float valve is a cylindrical air float with an open lower end and a circular tubular sleeve arranged on the upper part, the sealing gasket is installed in the circular tubular sleeve of the float valve, and the water outlet nozzle is fixed at the lower end of the water inlet pipe and inserted into the circular tubular sleeve of the float valve together with the water inlet pipe. Water is injected into the water storage cylinder through the inlet pipe and the water outlet nozzle, the water level in the water storage cylinder rises, and the float valve moves upward accordingly, pushing the sealing gasket to seal the lower end of the water outlet nozzle, preventing water from being injected into the water storage cylinder, thereby achieving the purpose of controlling the water level of the water storage cylinder; the height of the water level in the water storage cylinder can be adjusted by controlling the length of the water inlet pipe inserted into the water storage cylinder; the water-absorbing material is in the shape of a circular tube, the lower half of which is wrapped around the outside of the float valve, and the upper half is evenly provided with circular through holes, thereby increasing the contact area between the water-absorbing material and the air, and the water stored in the water storage cylinder is transported upward from the bottom of the water storage cylinder to the top of the float valve under the adsorption effect of the water-absorbing material.

[0010] The automatic watering device has two working modes.

[0011] Gaseous water circulation working mode: by installing a pressure reducing device at the outlet of the water source to reduce the water pressure of the water pipeline, the water pressure in the water inlet pipe is kept at a relatively low pressure state, and the water level controller composed of the water inlet pipe, the water outlet nozzle, the sealing gasket and the float valve automatically regulates the water level in the water storage cylinder; the length of the water inlet pipe inserted into the water storage cylinder is adjusted to control the water level in the water storage cylinder below the overflow hole; at this time, the automatic water application device enters the gaseous water circulation working mode, and the water stored in the water storage cylinder cannot flow directly into the soil, but is transported upward from the bottom of the water storage cylinder to the top of the float valve under the adsorption effect of the water-absorbing material, and the circular through holes evenly arranged on the upper half of the water-absorbing material increase the contact area between water and air, thereby improving the evaporation efficiency of water and turning water into water vapor. The water vapor enters the soil through the overflow hole and the exhaust hole on the side of the circular tube of the water storage cylinder, thereby achieving the purpose of applying water to the soil in the form of gaseous water circulation.

[0012] Direct watering working mode: short-circuit the pressure reducing device at the water source outlet, and the water source directly supplies water to the water pipeline, thereby increasing the water pressure in the water pipeline and making the water pressure in the water inlet pipe at a relatively high pressure state. Due to the increase in water pressure, the water level equilibrium state formed by the automatic watering device in the gaseous water circulation working mode is broken, so that more water is injected into the water storage cylinder, and the water level in the water storage cylinder rises, reaching or even exceeding the overflow hole. At this time, the automatic watering device enters the direct watering working mode, and the water stored in the water storage cylinder flows directly into the soil through the overflow hole on the side of the circular tube of the water storage cylinder, directly irrigating the soil and achieving the purpose of applying water to the soil by direct watering.

[0013] The beneficial effects of the automatic watering device described in the present invention are: through a simple method of controlling the water supply pressure, the purpose of controlling the automatic watering device to switch between the two working modes of gaseous water circulation and direct watering is achieved; the gaseous water circulation working mode replenishes water into the soil in the form of water vapor, providing the minimum necessary water conditions for the long-term uninterrupted growth of seedlings, achieving the maximum water-saving effect; the direct watering working mode directly replenishes liquid water into the soil, which can quickly solve the problem of water shortage of seedlings in extreme environments. The automatic watering device described in the present invention directly replenishes water from the soil, and the water loss is very small and can be ignored, which is more water-saving than the traditional watering method.

[0014] In order to give full play to the advantages of the seedling planting protection device and the automatic watering device described in the present invention, the present invention provides a tree planting method, which is characterized by: seedlings are planted in a deep pit manner, and the seedling planting protection device and the automatic watering device described in the present invention create a microenvironment with watering function and sufficient lighting conditions below the ground, providing a good growth environment for seedlings, improving the survival rate of seedlings, and achieving the purpose of improving the survival rate of afforestation.

[0015] The tree planting method of the present invention comprises the following steps: A. Dig a pit with a certain diameter and depth at the location where trees need to be planted, bury the automatic watering device of the present invention in the soil at the bottom edge of the pit, and make the side with overflow holes and exhaust holes face the center of the pit, and add nutrient-rich nutrient soil at the bottom of the pit; B. Put the protective tube of the present invention into a deep pit, with a portion of the protective tube exposed above the ground and the surrounding area filled with soil; C. Sow the seedlings in the nutrient soil at the bottom of the protective tube, or insert the seedling cuttings, or plant the seedlings to complete the planting steps; D. Put the lighting protection cover on the top of the protection tube, and supply water to the automatic watering device through the water pipeline, so as to form a semi-enclosed microenvironment surrounded by the seedling planting protection device, deep below the ground, with watering function and sufficient light conditions, so as to promote the growth and development of seedlings; E. According to the lighting conditions, adjust the direction of the lighting window of the lighting protection cover. When the direction of the lighting window is away from the incident direction of sunlight, the amount of incident light can be reduced, thereby reducing the light intensity in the seedling planting protection device. Conversely, the light intensity in the seedling planting protection device can be increased; F. When the root system of the seedlings is mature and can adapt to the external environment, remove the light protection cover, and the seedlings are in direct contact with the outside world, so that the seedlings can grow freely, so as to achieve the purpose of training the seedlings and improve their ability to adapt to the environment; G. When the seedlings have fully adapted to the external environment, remove the protective tube and automatic watering device, retain the deep pit, or fill the deep pit to complete the tree planting work.

[0016] The beneficial effects of a tree planting method provided by the present invention are as follows: by utilizing the seedling planting protection device and the automatic watering device provided by the present invention and adopting a deep pit planting method deep below the ground, the moisture inside the soil can be more fully utilized, the amount of water applied can be reduced, and at the same time the ability of the seedlings to resist high temperature and severe cold can be improved, and the windproof function can be combined; light enters the interior of the seedling planting protection device through the light-collecting protection cover, and after multiple reflections by the reflective layer, enters the bottom of the protection tube, providing sufficient light for the seedlings; the working mode of the automatic watering device is adjusted by controlling the water pressure, and the necessary moisture is provided for the growth of the seedlings continuously for a long time, thereby achieving the purpose of water saving; under the protection of the good microenvironment created by the seedling planting protection device and the automatic watering device, the survival rate of the seedlings is greatly improved, thereby achieving the purpose of carrying out afforestation in a harsh environment where water is scarce, desertification is severe, and trees cannot be planted.

[0029] Figure 3 A schematic diagram of the structural decomposition of a protective tube 2 of a seedling planting protection device described in the present invention is shown.

[0030] like Figure 3 As shown, the protective tube assembly 201 is a hollow heat-insulating material with a double-layer structure.

[0031] The protective tube reflective layer 202 is a wavy silver reflective layer, which forms a convex mirror effect, so that the incident light is scattered, and the problem of the reflective surface converging the light to form a high-temperature spot and burn the seedlings is prevented.

[0032] Figure 4 The schematic diagram of the structural decomposition of the automatic watering device 3 of the present invention is shown.

[0033] like Figure 4As shown, the automatic water application device 3 is composed of a water storage cylinder tube 303, a water storage cylinder upper cover 302, a locking cap 301, a water storage cylinder lower cover 306, a water inlet pipe 313, a water outlet nozzle 312, a sealing gasket 311, a float valve 309, and a water absorbing material 307.

[0034] The water storage cylinder upper cover 302 and the water storage cylinder lower cover 306 close the water storage cylinder circular tube 303 from both ends to form a cylindrical water storage cylinder; an overflow hole 305 and an exhaust hole 304 are arranged on the side of the water storage cylinder circular tube 303, and the overflow hole 305 is below the exhaust hole 304.

[0035] A through-hole boss with a conical upper portion and threads is arranged in the middle of the water storage cylinder cover 302, and three notches are evenly arranged on the boss to produce a clamping effect; the locking cap 301 is provided with corresponding threads and a conical contact surface; the water inlet pipe 313 is inserted from the through-hole in the middle of the water storage cylinder cover 302, and is locked and fixed on the water storage cylinder cover 302 by the locking cap 301.

[0036] The float valve 309 is a cylindrical air float with an open lower end and a cylindrical sleeve disposed on the upper portion. A float valve guide hole 310 is disposed on the cylindrical sleeve of the float valve 309 , and water flows out through the float valve guide hole 310 .

[0037] The sealing gasket 311 is a sheet-shaped circular rubber sealing member installed in the circular tubular sleeve of the float valve 309 .

[0038] The upper part of the water outlet nozzle 312 is in the shape of a circular tube, and the lower part is in the shape of a cone with a narrowed lower edge. The water outlet nozzle 312 is inserted into the entry pipe 313 and combined with the water inlet pipe 313; the water outlet nozzle 312 is inserted into the circular tubular sleeve of the float valve 309 together with the water inlet pipe 313, and the lower edge of the water outlet nozzle 312 contacts the sealing gasket 311, which can more effectively block the water flow.

[0039] The water inlet pipe 313, the water outlet nozzle 312, the sealing gasket 311, and the float valve 309 constitute a water level controller for controlling the water level 314 of the water storage cylinder; water is injected into the water storage cylinder through the inlet pipe 313 and the water outlet nozzle 312, and the water level 314 of the water storage cylinder rises. Under the action of buoyancy, the float valve 309 moves upward, pushing the sealing gasket 311 to block the lower end of the water outlet nozzle 312, preventing water from being injected into the water storage cylinder, thereby achieving the purpose of controlling the water level 314 of the water storage cylinder; the lower end of the float valve 309 is an open structure, and under the action of water pressure, a float valve cavity water level 315 is formed inside the cavity of the float valve 309; the height of the water level 314 of the water storage cylinder can be adjusted by controlling the length of the water inlet pipe 313 inserted into the water storage cylinder.

[0040] The water-absorbing material 307 is in the shape of a circular tube with a variable diameter. The lower half of the water-absorbing material 307 is wrapped around the outside of the float valve 309, and the upper half is evenly provided with circular through holes 308. The function of the circular through holes 308 is to increase the contact area between the water-absorbing material 307 and the air. The water stored in the water storage cylinder is transported upward from the bottom of the water storage cylinder to the top of the float valve 309 under the adsorption effect of the water-absorbing material 307.

[0041] The automatic watering device 3 has two working modes: a gaseous water circulation working mode and a direct watering working mode.

[0042] Figure 5 A schematic diagram of a gaseous water circulation working mode of an automatic water application device 3 described in the present invention is shown.

[0043] like Figure 5 As shown, by installing a pressure reducing device at the outlet of the water source to reduce the water pressure in the water delivery pipeline 4, the pressure p1 of the water injected into the water inlet pipe 313 is controlled to make p1 in a relatively low pressure state, and the water level controller is composed of the water inlet pipe 313, the water outlet nozzle 312, the sealing gasket 311, and the float valve 309 to realize the automatic control function of the water level 314 of the water storage cylinder; the length of the water inlet pipe 313 inserted into the water storage cylinder is adjusted to control the water level 314 of the water storage cylinder below the overflow hole 305, as shown in the partial view C; at this time, the automatic water application device 3 enters the gaseous water circulation In the working mode, the water stored in the water storage cylinder cannot flow directly into the soil 5, but is transported upward from the bottom of the water storage cylinder to the top of the float valve 309 under the adsorption effect of the water-absorbing material 307. The circular through holes 308 evenly arranged on the upper half of the water-absorbing material 307 increase the contact area between water and air, thereby improving the evaporation efficiency of water, turning water into water vapor. The water vapor enters the soil 5 through the overflow hole 305 and the exhaust hole 304 on the side of the circular tube 303 of the water storage cylinder, thereby achieving the purpose of applying water to the inside of the soil 5 in the form of gaseous water circulation.

[0044] Figure 6 It is a schematic diagram of a direct watering working mode of an automatic watering device 3 described in the present invention.

[0045] like Figure 6As shown, the pressure reducing device at the outlet of the water source is short-circuited, and the water source directly supplies water to the water delivery pipeline 4, so that the water pressure p2 in the water inlet pipe 313 is in a relatively high pressure state, p2>p1, breaking the water level equilibrium state formed by the water pressure p1 when the automatic water application device 3 is in the gaseous water circulation working mode, and the water level 315 in the float valve chamber rises, and the buoyancy of the float valve 309 decreases, so that more water is injected into the water storage cylinder, and the water level 314 in the water storage cylinder rises to reach or even exceed the overflow hole 305, as shown in the partial view D; at this time, the automatic water application device 3 enters the direct irrigation working mode, and the water stored in the water storage cylinder directly flows into the soil 5 through the overflow hole 305 on the side of the water storage cylinder circular tube 303, and the soil 5 is directly irrigated, so as to achieve the purpose of applying water to the inside of the soil 5 by direct irrigation.

[0046] like Figure 1 As shown, the present invention provides a tree planting method, and the specific technical solution includes the following steps: A. Dig a pit with a certain diameter and depth at the location where trees need to be planted, bury the automatic watering device 3 of the present invention in the soil 5 at the bottom edge of the pit, and make the side with the overflow hole 305 and the exhaust hole 304 face the center of the pit, and add nutrient soil 7 at the bottom of the pit; B. Put the protective tube 2 of the present invention into a deep pit, with a portion of the protective tube 2 exposed above the ground and the surrounding area filled with soil; C. Taking planting seedlings as an example, the seedlings 6 are implanted in the nutrient soil 7 at the bottom of the protective tube 2 to complete the planting steps; D. Put the lighting protection cover 1 on the top of the protection tube 2, and supply water to the automatic watering device 3 through the water pipe 4, so as to form a semi-enclosed microenvironment surrounded by the lighting protection cover 1 and the protection tube 2, deep below the ground, with watering function and sufficient light conditions, so as to provide a good living environment for the growth and development of the seedlings 6; E. According to the lighting conditions, adjust the direction of the lighting window of the lighting protection cover 1. When the direction of the lighting window is away from the incident direction of sunlight, the amount of incident light can be reduced, thereby reducing the illumination in the seedling planting protection device. Conversely, the illumination in the seedling planting protection device can be increased; F. When the root system of the seedling plant 6 is mature and can adapt to the external environment, remove the lighting protection cover 1, so that the seedling plant 6 is in direct contact with the outside world, and the seedling plant 6 grows freely, so as to achieve the purpose of training the seedling and improve the adaptability of the seedling plant 6 to the external environment; G. When the seedlings and plants 6 are fully adapted to the external environment, the protective tube 2 and the automatic watering device 3 are taken out, and the deep pit is retained or filled to complete the tree planting work.
