Description

Technical Field

[0001] This utility model relates to the field of asparagus cultivation technology, specifically to a greenhouse for asparagus cultivation. Background Technology

[0002] Asparagus is a vegetable, specifically the seedling of Asparagus spp., a perennial herbaceous plant belonging to the Asparagaceae family and the Asparagus genus. Asparagus has high requirements for its growing environment, so a greenhouse is needed to provide a high-quality environment for it.

[0003] A greenhouse for asparagus cultivation, disclosed in CN216820937U, includes a greenhouse body, bearing seats, a transverse rotating shaft, a roller, and a longitudinal rotating shaft. The tops of the front and rear side walls inside the greenhouse body are rotatably connected to both ends of the transverse rotating shaft via bearing seats, and the tops of the left and right side walls inside the greenhouse body are also rotatably connected to both ends of the longitudinal rotating shaft via bearing seats. A first bevel gear and a second bevel gear are respectively provided at both ends of the transverse and longitudinal rotating shafts. This invention utilizes automatically retractable insulating cotton cloth installed around the perimeter of the greenhouse's inner walls. When the temperature is low, the insulating cotton cloth is lowered to cover the perimeter of the greenhouse, providing insulation and effectively increasing the internal temperature, thus accelerating asparagus growth. Furthermore, when heating equipment is needed due to low temperatures, the insulation effect of the cotton cloth allows the heating equipment to be turned off after a period of time, eliminating the need for continuous heating and significantly reducing costs.

[0004] However, the device does not have a structure for easy retraction of the insulation curtain. In cold weather, the insulation curtain can play a certain role in heat preservation; but in warm weather or when ventilation and cooling are needed, if the insulation curtain cannot be retracted, it will hinder the air circulation inside and outside the greenhouse, resulting in excessively high temperature inside the greenhouse, which is not conducive to the growth of crops such as asparagus.

[0005] To address the aforementioned issues, we have made innovative designs based on the existing greenhouse structure for asparagus cultivation. Utility Model Content

[0006] The purpose of this utility model is to provide a greenhouse for asparagus cultivation, in order to solve the problem mentioned in the background art that the device does not have a structure for easy rolling up the heat-insulating curtain. In cold weather, the heat-insulating curtain can play a certain role in heat preservation; however, in warm weather or when ventilation and cooling are required, if the heat-insulating curtain cannot be rolled up, it will hinder the air circulation inside and outside the greenhouse, resulting in excessively high internal temperature, which is not conducive to the growth of crops such as asparagus.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse for asparagus cultivation, comprising supporting legs with side skirts fixedly connected to both sides of the supporting legs; a top glass panel fixedly connected to the upper end of the supporting legs; further comprising: an insulating curtain rolled up on the upper end of the top glass; a driving assembly disposed on the upper end of the top glass; the insulating curtain being driven by the driving assembly to move in a straight line from back to front along the upper end of the top glass and laid on the upper end of the top glass; and an insulation component disposed on the inner side of the side skirts; the insulation component being used to heat the inside of the greenhouse.

[0008] Preferably, the outer side of the support leg is bonded to a side wall, and two sets of side walls are arranged symmetrically about the midpoint of the top glass.

[0009] Preferably, a storage frame is fixedly installed on the upper end of the top glass, and a guide rod is fixedly connected to the inner side of the storage frame, with the bottom of the guide rod in contact with the heat-insulating curtain.

[0010] Preferably, a concentric shaft is rotatably connected to the inner side of the storage frame, and a spiral spring is connected between the end of the concentric shaft and the outer wall of the storage frame. An insulating curtain is wrapped around the outer side of the concentric shaft, and ear chambers are provided on the left and right sides of the insulating curtain. Ventilation holes are opened on the surface of the ear chambers on both sides of the rear half of the insulating curtain.

[0011] Preferably, the drive assembly includes a servo motor, a threaded rod, and a threaded connector. The servo motor is fixedly mounted on the upper end of the top glass, and the output end of the servo motor is fixedly connected to the threaded rod. The threaded rod is threadedly connected to the outer side of the threaded connector, and the threaded connector is connected to the tail end of the insulation curtain.

[0012] Preferably, the drive assembly further includes a sliding rod and a sliding rail. The sliding rod is fixedly connected to the upper end of the threaded connector, and the top of the sliding rod is slidably connected to the inner side of the sliding rail, while the sliding rail is fixedly connected to the outer side of the storage frame.

[0013] Preferably, the heat insulation component includes a fixing plate, a battery, a temperature sensor, a control module, and a heating tube. The fixing plate is fixedly connected to the inner side of the side skirt, and the battery is fixedly installed on the inner side of the fixing plate. The temperature sensor is fixedly installed on the inner side of the fixing plate, the control module is fixedly installed on the inner side of the fixing plate, and the heating tube is fixedly installed on the inner side of the fixing plate. The battery is electrically connected to the temperature sensor and the heating tube respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Insulation curtain adjustment structure: When it is necessary to increase the insulation performance of the inner side of the greenhouse, this structure operates a servo motor, which drives the threaded rod to rotate. The rotation of the threaded rod will drive the threaded connector on the outer threaded connection to move forward. When the threaded connector moves forward, it will drive the rolled-up insulation curtain to move forward as well. At the same time, the spiral spring will store force. As the insulation curtain is continuously laid forward along the top of the top glass, the inner side of the greenhouse will be sealed, thus insulating the inner side of the greenhouse.

[0016] Furthermore, when ventilation and supplemental lighting are needed inside the greenhouse, the servo motor runs in reverse, causing the output of the servo motor to drive the threaded connector to move backward along the top of the top glass. After the first end of the insulation curtain loses the pull of the threaded connector, the spring force of the spiral spring will cause the concentric shaft to roll up the insulation curtain, thus making the top of the greenhouse open for ventilation and supplemental lighting.

[0017] 2. Insulation structure: This structure uses a temperature sensor to detect temperature changes inside the greenhouse. When the temperature inside the greenhouse is too low, the temperature sensor transmits the information to the control module. The control module then controls the battery to supply power to the heating element. The heating element converts electrical energy into heat, thereby heating the inside of the greenhouse and maintaining the temperature inside the greenhouse at a level suitable for asparagus growth.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 This utility model provides a technical solution: a greenhouse for asparagus cultivation, comprising:

[0028] like Figures 1-6 The present invention provides a technical solution for an asparagus cultivation greenhouse, comprising: a support leg 1, with side skirts 2 fixedly connected to both sides of the support leg 1; a top glass 3, fixedly connected to the upper end of the support leg 1; further comprising: an insulation curtain 8, which is rolled up on the upper end of the top glass 3; a drive assembly 9, which is disposed on the upper end of the top glass 3; the insulation curtain 8 is driven by the drive assembly 9 to move in a straight line from back to front along the upper end of the top glass 3 and laid on the upper end of the top glass 3; and an insulation assembly 10, which is disposed inside the side skirts 2; the insulation assembly 10 is used to heat the inside of the greenhouse.

[0029] The support leg 1 is bonded to the outer side of a side wall 11, and two sets of side walls 11 are symmetrically arranged about the midpoint of the top glass 3. A storage frame 4 is fixedly installed on the upper end of the top glass 3, and a guide rod 5 is fixedly connected to the inner side of the storage frame 4, with the bottom of the guide rod 5 in contact with the thermal insulation curtain 8. A concentric shaft 6 is rotatably connected to the inner side of the storage frame 4, and a spiral spring 7 is connected between the end of the concentric shaft 6 and the outer wall of the storage frame 4. The thermal insulation curtain 8 is wrapped around the outer side of the concentric shaft 6, and ear chambers 801 are provided on the left and right sides of the thermal insulation curtain 8. The drive assembly 9 includes a servo motor 901 and a threaded rod 9. 02 and threaded connector 903, servo motor 901 is fixedly installed on the upper end of top glass 3, and threaded rod 902 is fixedly connected to the output end of servo motor 901. Threaded connector 903 is threadedly connected to the outer side of threaded rod 902, and threaded connector 903 is connected to the tail end of heat insulation curtain 8; drive assembly 9 also includes sliding rod 904 and sliding rail 905. Sliding rod 904 is fixedly connected to the upper end of threaded connector 903, and the top of sliding rod 904 is slidably connected to the inner side of sliding rail 905, and sliding rail 905 is fixedly connected to the outer side of storage frame 4;

[0030] In this embodiment: When it is necessary to increase the heat preservation performance of the inner side of the greenhouse, the servo motor 901 is operated, so that the output end of the servo motor 901 drives the threaded rod 902 to rotate. The rotation of the threaded rod 902 will drive the threaded connector 903 connected to the outer thread to move forward. When the threaded connector 903 moves forward, it will drive the rolled-up heat preservation curtain 8 to move forward as well. At the same time, the spiral spring 7 stores power. As the heat preservation curtain 8 is continuously laid forward along the upper end of the top glass 3, the ear room 801 can cooperate with the side skirt 2 to cover the outer wall of the greenhouse, so that the inner side of the greenhouse is in a sealed state and heat preservation is provided for the inner side of the greenhouse. When it is necessary to provide ventilation and supplemental lighting for the inner side of the greenhouse, the servo motor 901 is operated in reverse, so that the output end of the servo motor 901 drives the threaded connector 903 to move backward along the upper end of the top glass 3. After the first end of the heat preservation curtain 8 loses the pull of the threaded connector 903, the elastic force of the spiral spring 7 will cause the concentric shaft 6 to roll up the heat preservation curtain 8, so that the upper end of the greenhouse is in an open state for ventilation and supplemental lighting.

[0031] Furthermore, such as Figure 6 As shown, ventilation holes 802 are provided on the surface of the ear chambers 801 on both sides of the rear half of the insulation curtain 8. If it is necessary to temporarily dissipate heat or release water vapor inside the greenhouse, the insulation curtain 8 can be controlled by the servo motor 901 and the threaded connector 903 to continue rolling up to the rear half. At this time, the ventilation holes 802 on the surface of the ear chambers 801 will be exposed for heat dissipation and water vapor release.

[0032] like Figure 1 , Figure 7The present invention provides a technical solution: a greenhouse for asparagus cultivation, which discloses that: the heat preservation component 10 includes a fixing plate 1001, a storage battery 1002, a temperature sensor 1003, a control module 1004, and a heating tube 1005. The fixing plate 1001 is fixedly connected to the inner side of the side skirt 2, and the storage battery 1002 is fixedly installed on the inner side of the fixing plate 1001. The temperature sensor 1003 is fixedly installed on the inner side of the fixing plate 1001, the control module 1004 is fixedly installed on the inner side of the fixing plate 1001, and the heating tube 1005 is fixedly installed on the inner side of the fixing plate 1001. The storage battery 1002 is electrically connected to the temperature sensor 1003 and the heating tube 1005 respectively.

[0033] In this embodiment: the temperature sensor 1003 senses the temperature change inside the greenhouse. When the temperature inside the greenhouse is too low, the temperature sensor 1003 will transmit the sensed information to the control module 1004. The control module 1004 controls the battery 1002 to provide power to the heating tube 1005. The heating tube 1005 converts electrical energy into heat, thereby heating the inside of the greenhouse and maintaining the temperature inside the greenhouse at 18℃-20℃. Asparagus grows most efficiently at this temperature.
