Description

Technical Field

[0001] The present invention relates to the technical field of lavender cultivation, and specifically to a greenhouse for winter lavender seedling raising. Background Technique

[0002] Since winter seedling raising is off-season seedling raising, and temperature and humidity are the most important during the seedling raising process. Therefore, in winter, in order to meet the temperature requirements during the seedling raising process, it is necessary to heat and keep warm the seedling raising environment, and the most important of which is heat preservation. The commonly used heating facilities at present are to build a plastic film greenhouse and install a floor heating system inside the greenhouse for heating. The heat brought by the flowing hot water is used to heat the greenhouse, so that the temperature inside the greenhouse is controlled at about 25 degrees Celsius. In order to reduce the loss of heat, generally, straw curtains (the heat preservation ability is generally 5 to 6 degrees Celsius), paper quilts (the heat preservation ability is 3 to 5 degrees Celsius) or cotton quilts (the heat preservation ability is 7 to 10 degrees Celsius) are covered outside the greenhouse for heat preservation. The plastic film greenhouse itself has the function of moisture preservation, and the relative humidity inside is 10% to 20% higher than that outside. Coupled with the installation of sprinkler irrigation inside the greenhouse, the humidity inside the greenhouse is controlled at 50% to 60% during the day and 80% to 90% at night. Lavender is a perennial semi-shrub, cold-tolerant, and the whole plant (including flowers) is rich in a large amount of volatile oils. It can overwinter with snow cover in winter, is drought-tolerant, afraid of waterlogging, suitable for growing in sandy loam, and likes sunlight.

[0003] The patent publication number CN205682006U discloses a winter lavender seedling raising greenhouse, which can meet the heat preservation performance of the greenhouse without increasing the bearing capacity of the greenhouse frame and the rolling force of the rolling machine in the cold season. Moreover, the heat preservation layer is arranged inside the greenhouse, which can effectively avoid problems such as deviation, aging, damage to the film and decline in heat preservation performance caused by the heat preservation layer being exposed to the sun, rain and wind outside the environment, and also avoid polluting the film and affecting the light transmittance of the greenhouse film. At the same time, it can also extend the service life of the internal heat preservation layer and ensure the heat preservation effect. Adjust measures to local conditions and make rational use of the heat preservation and constant temperature properties of the soil. Combine semi-underground planting and modern greenhouse facilities, which not only makes the temperature and humidity inside the greenhouse controllable, but also reduces the cost of replacing the heat preservation quilt due to its reduced performance. However, the following problems still exist in the actual use of this patent:

[0004] Although the heat preservation layer of this winter lavender seedling raising greenhouse is arranged inside the greenhouse, which can effectively avoid problems such as deviation, aging, damage to the film and decline in heat preservation performance caused by the heat preservation layer being exposed to the sun, rain and wind outside the environment. However, because the heat preservation layer is arranged inside the greenhouse, the light transmittance of the film is affected to a certain extent, thus affecting the photosynthesis of lavender and being not conducive to the growth of lavender. At the same time, it is not convenient to ventilate and exchange air inside the greenhouse, which is easy to cause insect pests and affect the normal growth of lavender.

[0005] Therefore, a greenhouse for winter lavender seedling raising is proposed to facilitate solving the problems mentioned above. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: For the greenhouse for winter lavender seedling raising, when it is necessary to carry out the lighting effect on the planted lavender, the plastic film can be stored on one side, so that the top of the entire greenhouse is opened, which is convenient for the lavender to carry out photosynthesis. At the same time, the air inside the greenhouse can be circulated quickly, improving the growth environment of the lavender. Since the heat preservation quilt is arranged inside the plastic film, the heat preservation effect of the greenhouse can be improved while avoiding the heat preservation quilt from being exposed to the wind and sun, which affects the service life of the heat preservation quilt. The ventilation and air exchange of the greenhouse are carried out through natural wind, so as to achieve the effect of saving energy. At the same time, the rotating block and the ventilation fan can be connected to an external energy storage power supply and power generation equipment, and electric energy is stored by means of wind power generation. The specific content is as follows:

[0022] 1. By setting the opening and closing mechanism, not only can the opening and closing motor drive the first sprocket transmission component and the opening and closing threaded rod to rotate, so that the opening and closing threaded sleeve drives the first bracket and the first inclined plate to move on the top of the greenhouse planting frame. At the same time, under the action of the first roller, the movement of the second inclined plate and the second bracket can be realized. Since the plastic film is connected between the first bracket, the first inclined plate, the second inclined plate and the second bracket, the unfolding and closing of the plastic film can be realized. When it is necessary to carry out the lighting effect on the planted lavender, the plastic film can be stored on one side, so that the top of the entire greenhouse is opened, which is convenient for the lavender to carry out photosynthesis. At the same time, the air inside the greenhouse can be circulated quickly, improving the growth environment of the lavender. When lighting is not required, the top of the greenhouse is closed. When closing the top of the greenhouse, the second roller drives the second sprocket transmission component and the rotating gear to rotate. By using the meshing connection between the rotating gear and the meshing rack, the stable rotation of the second roller can be realized, avoiding the phenomenon of the second roller slipping. At the same time, the second sprocket transmission component drives the humidifying bracket and the humidifying nozzle to rotate, and the water source is externally connected through the connecting pipe to humidify the inside of the greenhouse, and uniform humidification inside the greenhouse can be realized. The inside of the greenhouse can be heated by the heater inside the second bracket, and the temperature and humidity inside the greenhouse are regulated in cooperation with the temperature and humidity sensor, providing the environment required for lavender planting and improving the growth effect of the lavender. Since the heat preservation quilt is arranged inside the plastic film, the heat preservation effect of the greenhouse can be improved while avoiding the heat preservation quilt from being exposed to the wind and sun, which affects the service life of the heat preservation quilt;

[0023] 2. By setting up the ventilation mechanism, not only can the rotating motor drive the rotating worm to rotate, and due to the meshing connection between the rotating worm and the rotating worm wheel, the rotating worm wheel can drive the rotating disc to rotate. With the limiting effect of the spiral chute inside the rotating disc, the spiral slider drives the ventilation baffle to slide, capable of closing the connection hole. When ventilation and air exchange in the greenhouse are needed, the connection hole is opened, and when ventilation and air exchange in the greenhouse are not needed, the connection hole is closed, preventing the loss of temperature and humidity inside the greenhouse and affecting the growth of lavender. Ventilation and air exchange inside the greenhouse are carried out through the ventilation fan inside the fan cover. At the same time, the natural wind outside drives the air guide cover, the rotating connecting rod, and the rotating block to rotate, causing the rotating block to drive the connecting shaft and the transmission disc to rotate. Due to the meshing connection between the meshing tooth ring, the transmission slave gear, and the transmission master gear, the rotation of the transmission connecting rod, the bevel gear transmission assembly, and the ventilation fan can be realized, enabling ventilation and air exchange in the greenhouse through natural wind, thus achieving the effect of energy conservation. At the same time, the rotating block and the ventilation fan can be connected to an external energy storage power supply and power generation equipment, and electric energy is stored through wind power generation, facilitating the utilization of wind energy. The external energy storage power supply and power generation equipment are prior arts, so this case does not describe the energy storage power supply and power generation equipment in detail.

Among them, a ventilation hole 105 is opened at the central position inside the triangular plate 104, a fixing block 106 is fixedly installed on the top of the triangular plate 104, and an opening and closing sliding rod 107 is fixedly installed between the two fixing blocks 106. Among them, a number of sliding sleeves 108 are slidably connected to the outside of the opening and closing sliding rod 107. One side of the greenhouse planting frame 102 is fixedly installed with a motor cover 109, an opening and closing motor 110 is fixedly installed on one side inside the motor cover 109, an output end of the opening and closing motor 110 is fixedly connected with a first sprocket transmission assembly 111, opening and closing threaded rods 112 are symmetrically installed on one side of the first sprocket transmission assembly 111, an opening and closing threaded sleeve 113 is threadedly connected to the outside of the two opening and closing threaded rods 112, a first bracket 114 is fixedly installed on the outside of the two opening and closing threaded sleeves 113, a first inclined plate 115 is fixedly installed on the top of the first bracket 114, the first inclined plate 115 is fixedly connected with the sliding sleeve 108, a number of second inclined plates 116 are arranged on one side of the first inclined plate 115, the second inclined plate 116 is fixedly connected with the sliding sleeve 108, and a second bracket 117 is fixedly installed at the bottom of the second inclined plate 116. By driving the first sprocket transmission assembly 111 and the opening and closing threaded rods 112 to rotate by the opening and closing motor 110, the opening and closing threaded sleeve 113 drives the first bracket 114 and the first inclined plate 115 to move on the top of the greenhouse planting frame 102. At the same time, under the action of the first roller 119, the movement of the second inclined plate 116 and the second bracket 117 can be realized. Since the plastic film 131 is connected between the first bracket 114, the first inclined plate 115, the second inclined plate 116 and the second bracket 117, the unfolding and closing of the plastic film 131 can be realized.

[0038] A heater 118 is fixedly installed on the inner side of the second support 117, a first roller 119 is fixedly installed at the bottom of the second support 117, a second sprocket drive assembly 120 is rotatably connected to the outer side of the first support 114, a rotating gear 121 is fixedly connected to the outer bottom of the second sprocket drive assembly 120, a meshing rack 122 is meshed and connected to the bottom of the rotating gear 121, a second roller 123 is fixedly installed at the bottom of the first support 114, a humidifying support 124 is fixedly connected to the top of the second sprocket drive assembly 120, a humidifying nozzle 125 is fixedly installed at the bottom of the humidifying support 124. When light is needed for the planted lavender, the plastic film 131 can be stored on one side to open the top of the entire greenhouse, facilitating the photosynthesis of lavender and enabling the rapid circulation of the air inside the greenhouse, improving the growth environment of lavender. When light is not needed, the top of the greenhouse is closed. When closing the top of the greenhouse, the second roller 123 drives the second sprocket drive assembly 120 and the rotating gear 121 to rotate. Utilizing the meshing connection between the rotating gear 121 and the meshing rack 122, the stable rotation of the second roller 123 can be achieved, avoiding the phenomenon of the second roller 123 slipping. At the same time, the second sprocket drive assembly 120 drives the humidifying support 124 and the humidifying nozzle 125 to rotate, and water is supplied from an external water source through the connecting pipe 126 to humidify the inside of the greenhouse, enabling uniform humidification inside the greenhouse.

[0039] A connecting pipe 126 is rotatably connected to one side of the humidifying support 124, a temperature and humidity sensor 127 is fixedly installed at the bottom of the sliding sleeve 108, connecting hinges 128 are symmetrically installed up and down on both sides of the one-side limit baffle 103, a greenhouse door 129 is rotatably connected to the outer sides of the two connecting hinges 128, a handle 130 is fixedly installed on one side of the middle of the greenhouse door 129, the plastic film 131 is fixedly connected to the first support 114, the first inclined plate 115, the second inclined plate 116 and the second support 117 respectively, a heat preservation quilt 132 is fixedly installed on the inner side of the plastic film 131. The heater 118 inside the second support 117 can heat the inside of the greenhouse, and cooperate with the temperature and humidity sensor 127 to regulate the temperature and humidity inside the greenhouse, providing the environment required for lavender cultivation and improving the growth effect of lavender. Since the heat preservation quilt 132 is arranged inside the plastic film 131, while improving the heat preservation effect of the greenhouse, the heat preservation quilt 132 can be protected from being exposed to the wind, sun and rain, which affects the service life of the heat preservation quilt 132.

[0040] The ventilation mechanism 2 includes a ventilation support 201 which is fixedly installed inside the ventilation hole 105. Limited position sliding grooves 202 are provided around the inside of the ventilation support 201, and limited position sliding blocks 203 are slidably connected inside the limited position sliding grooves 202. Rotating supports 204 are symmetrically arranged at the bottom of the ventilation support 201, and the rotating supports 204 are fixedly installed on the outer side of the triangular plate 104. A rotating motor 205 is fixedly installed on the outer side of one rotating support 204. The output end of the rotating motor 205 is fixedly connected with a rotating worm 206. The top of the rotating worm 206 is meshed and connected with a rotating worm gear 207. A rotating disc 208 is fixedly installed inside the rotating worm gear 207. Spiral sliding grooves 209 are provided around the inside of the rotating disc 208, and spiral sliding blocks 210 are slidably connected inside the spiral sliding grooves 209. A ventilation baffle 211 is fixedly installed on the outer side of the spiral sliding block 210. The spiral sliding block 210 is fixedly connected with the limited position sliding block 203. Connecting holes 212 are provided inside both the ventilation support 201 and the rotating disc 208. By driving the rotation of the rotating worm 206 with the rotating motor 205, and using the characteristic of the meshing connection between the rotating worm 206 and the rotating worm gear 207, the rotation of the rotating worm gear 207 can drive the rotation of the rotating disc 208. By the limiting effect of the spiral sliding groove 209 inside the rotating disc 208, the spiral sliding block 210 drives the ventilation baffle 211 to slide, and the connecting hole 212 can be closed. When ventilation and air exchange of the greenhouse are required, the connecting hole 212 is opened. When ventilation and air exchange of the greenhouse are not required, the connecting hole 212 is closed, avoiding the loss of temperature and humidity inside the greenhouse and affecting the growth of lavender.

[0041] On one side of the ventilation support 201, a fan cover 213 is fixedly installed. Inside the fan cover 213, a fan support 214 is fixedly installed. At the center position inside the fan support 214, a fan rotating sleeve 215 is fixedly installed. The ventilation fan 216 is rotatably connected to the fan rotating sleeve 215. One end of the ventilation fan 216 is fixedly connected to a bevel gear transmission assembly 217. The top of the bevel gear transmission assembly 217 is fixedly connected to a transmission connecting rod 218. The top of the transmission connecting rod 218 is rotatably connected to a transmission support frame 219. Outside the transmission support frame 219, a transmission sleeve 220 is fixedly installed. At the top of the transmission support frame 219, a meshing gear ring 221 is fixedly installed. The inner ring of the meshing gear ring 221 is meshed with a driven transmission gear 222. Between the driven transmission gears 222, a driving transmission gear 223 is meshed. The driving transmission gear 223 is fixedly connected to the transmission connecting rod 218. The top of the driven transmission gear 222 is rotatably connected to a transmission disc 224. The top of the transmission disc 224 is fixedly connected to a connecting shaft 225. The top of the connecting shaft 225 is fixedly connected to a rotating block 226. On the outer side of the middle part of the rotating block 226, a rotating connecting rod 227 is fixedly installed. At the end of the rotating connecting rod 227, an air guiding cover 228 is fixedly installed. The ventilation fan 216 inside the fan cover 213 is used for ventilation and air exchange inside the greenhouse. At the same time, the natural wind outside drives the air guiding cover 228, the rotating connecting rod 227 and the rotating block 226 to rotate, so that the rotating block 226 drives the connecting shaft 225 and the transmission disc 224 to rotate. By using the meshing connection characteristics between the meshing gear ring 221, the driven transmission gears 222 and the driving transmission gear 223, the rotation of the transmission connecting rod 218, the bevel gear transmission assembly 217 and the ventilation fan 216 can be realized, and the ventilation and air exchange of the greenhouse can be carried out through the natural wind, thus achieving the effect of energy saving.

[0042] On the outer side of the bottom of the rotating block 226, a plurality of connecting blocks 229 are fixedly installed. On the outer side of the connecting blocks 229, a rotating bearing 230 is fixedly installed. The rotating bearing 230 is rotatably connected to the transmission sleeve 220. The rotating block 226 and the ventilation fan 216 can be connected to an external energy storage power supply and power generation equipment. Electric energy is stored by means of wind power generation, which is convenient for the utilization of wind energy. The external energy storage power supply and power generation equipment are prior arts, so this case does not describe the energy storage power supply and power generation equipment in detail.

[0043] Working principle: Before using the greenhouse for winter lavender seedling raising, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, the opening and closing motor 110 drives the first sprocket drive assembly 111 and the opening and closing threaded rod 112 to rotate, causing the opening and closing threaded sleeve 113 to drive the first bracket 114 and the first inclined plate 115 to move on the top of the greenhouse planting frame 102. At the same time, under the action of the first roller 119, the movement of the second inclined plate 116 and the second bracket 117 can be realized. Since the plastic film 131 is connected between the first bracket 114, the first inclined plate 115, the second inclined plate 116 and the second bracket 117, the unfolding and closing of the plastic film 131 can be realized. When light is needed for the planted lavender, the plastic film 131 can be stored on one side, making the top of the entire greenhouse open, facilitating the photosynthesis of lavender, and at the same time enabling the rapid circulation of the air inside the greenhouse, improving the growth environment of lavender.

[0044] Secondly, when lighting is not required, close the top of the greenhouse. While closing the top of the greenhouse, the second roller 123 drives the second sprocket drive assembly 120 and the rotating gear 121 to rotate. Utilizing the meshing connection between the rotating gear 121 and the meshing rack 122, the stable rotation of the second roller 123 can be achieved, avoiding the phenomenon of the second roller 123 slipping. At the same time, the second sprocket drive assembly 120 drives the humidification bracket 124 and the humidifying nozzle 125 to rotate, and the water source is externally connected through the connecting pipe 126 to humidify the inside of the greenhouse, enabling uniform humidification inside the greenhouse. The heater 118 inside the second bracket 117 can heat the inside of the greenhouse, and cooperate with the temperature and humidity sensor 127 to regulate the temperature and humidity inside the greenhouse, providing the environment required for lavender planting and improving the growth effect of lavender. Since the heat preservation quilt 132 is arranged inside the plastic film 131, the heat preservation effect of the greenhouse can be improved while avoiding the heat preservation quilt 132 from being exposed to the wind and sun, which affects the service life of the heat preservation quilt 132.

[0045] Finally, the rotation motor 205 is used to drive the rotation of the rotation worm 206. By utilizing the meshing connection between the rotation worm 206 and the rotation worm wheel 207, the rotation worm wheel 207 can drive the rotation of the rotation disk 208. Due to the limiting effect of the internal spiral chute 209 of the rotation disk 208, the spiral slider 210 drives the ventilation baffle 211 to slide, capable of closing the connection hole 212. When ventilation and air exchange of the greenhouse are required, the connection hole 212 is opened; when ventilation and air exchange of the greenhouse are not required, the connection hole 212 is closed, avoiding the loss of temperature and humidity inside the greenhouse and affecting the growth of lavender. The ventilation and air exchange inside the greenhouse are carried out through the ventilation fan 216 inside the fan cover 213. Meanwhile, the natural wind outside drives the air guide cover 228, the rotation connecting rod 227, and the rotation block 226 to rotate, causing the rotation block 226 to drive the connection shaft 225 and the transmission disk 224 to rotate. By utilizing the meshing connection between the meshing tooth ring 221, the transmission driven gear 222, and the transmission main gear 223, the rotation of the transmission connecting rod 218, the bevel gear transmission assembly 217, and the ventilation fan 216 can be realized, and the ventilation and air exchange of the greenhouse can be carried out through natural wind, thus achieving the effect of energy conservation. At the same time, the rotation block 226 and the ventilation fan 216 can be connected to an external energy storage power supply and power generation equipment, and electric energy can be stored through wind power generation, facilitating the utilization of wind energy.
