Description

Technical Field

[0001] This utility model belongs to the field of agricultural auxiliary equipment technology, specifically relating to an intelligent electric cotton quilt rolling device for greenhouses. Background Technology

[0002] In winter, to maintain a suitable temperature for crop growth inside the greenhouse, it is usually necessary to cover the outside of the greenhouse with insulating quilts. However, crop growth also requires necessary sunlight, so it is necessary to frequently roll up (to allow light and increase temperature) and lower (to keep warm) the quilts according to weather conditions and day-night changes. This places high demands on the timeliness and precision of greenhouse management.

[0003] Currently, the operation of rolling up and placing cotton quilts in greenhouses generally relies on manual labor. However, manual operation often depends on experience to determine the starting and ending positions, which can easily lead to incomplete rolling up and placing, affecting the heat preservation or lighting effect. The entire operation process is relatively cumbersome and lacks convenience, seriously affecting the efficiency of rolling up and placing cotton quilts in greenhouses and restricting the improvement of greenhouse production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to improve the ease of operation when rolling up cotton quilts laid in greenhouses. In view of the shortcomings of the existing technology, this utility model provides an intelligent electric cotton quilt rolling device for greenhouses.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a smart electric cotton quilt rolling device for greenhouses, comprising:

[0007] A sliding track is configured to be installed along the top edge of the greenhouse and extend along the edge of the greenhouse to both ends of the greenhouse in the horizontal direction;

[0008] A roller shaft is slidably mounted on the sliding track and extends in a direction perpendicular to the sliding track. The roller shaft is wound around one end of a cotton quilt covering the greenhouse, and the other end of the cotton quilt is connected to a fixed roller that is fixedly connected to the greenhouse.

[0009] A rotary drive mechanism is drivenly connected to the roller shaft and slidably mounted on the sliding track;

[0010] A plurality of limiters are provided and spaced apart on the sliding track to contact the rotary drive mechanism.

[0011] A network-connected remote control forward and reverse switch is installed on the greenhouse and is electrically connected to the rotary drive mechanism and the limit switch via a cable.

[0012] Compared to existing technologies, the advantages of this invention include: a greenhouse intelligent electric quilt rolling device is constructed by setting up a sliding track, rollers, a quilt, a fixed roller, a rotary drive mechanism, a limit switch, and a networked remote control forward / reverse switch. The sliding track is configured to be installed along the top edge of the greenhouse and extends horizontally to both ends of the greenhouse. This allows the rollers and rotary drive mechanism to slide along the sliding track from one end of the greenhouse to the other. The rotary drive mechanism is driven by the rollers, which extend perpendicular to the sliding track and wrap around one end of the quilt covering the greenhouse. The other end of the quilt is connected to the fixed roller, which is fixedly connected to the greenhouse. When the network-controlled forward / reverse switch controls the rotation of the drive mechanism's roller shaft, the fixed roller holds the other end of the quilt in place. As the roller shaft rotates and curls one end of the quilt, the reverse force of the rotation pulls both the roller shaft and the drive mechanism along the sliding track, automating the opening of the quilt and significantly improving operational convenience. Furthermore, multiple limit switches are spaced apart on the sliding track. The drive mechanism contacts the limit switches to disconnect them. The network-controlled forward / reverse switch is installed on the greenhouse and electrically connected to both the drive mechanism and the limit switches via cables. This setup ensures that when the drive mechanism and the limit switches on the sliding track are engaged, the drive mechanism is de-energized, allowing the quilt to curl to the preset position. When the network-controlled forward / reverse switch reverses the drive mechanism, it contacts the limit switches near the ground on the sliding track, causing the quilt to extend to the set position and stop. This device automates the curling and covering of the quilt, further enhancing operational convenience. In addition, the network-connected remote control forward and reverse switch can be controlled via a network, making it convenient for operators to connect and operate remotely, further improving the ease of operation.

[0013] Optionally, the rotary drive mechanism includes a rotary drive assembly and a coupling. The rotary drive assembly is slidably mounted on the sliding track and is drivenly connected to the roller shaft via the coupling. The coupling has a built-in torque limiter.

A second sliding port is provided through the third track along the extension direction of the roller shaft. The coupling passes through the second sliding port located on one side of the greenhouse along the extension direction of the roller shaft, and the end of the roller shaft away from the coupling passes through the second sliding port located on the other side of the greenhouse along the extension direction of the roller shaft.

[0018] Optionally, the greenhouse intelligent electric cotton quilt rolling device further includes a pushing mechanism, which includes a swing component and a universal joint. The swing component is distributed at intervals with the greenhouse along the extension direction of the roller shaft. The swing component is connected to the rotary drive mechanism through the universal joint and is used to swing back and forth along the extension trajectory of the sliding track.

[0019] Optionally, the swing assembly includes a support base, a rotating shaft, and a telescopic rod. The support base and the greenhouse are spaced apart along the extension direction of the roller shaft. The rotating shaft is rotatably mounted on the support base and extends horizontally toward the greenhouse. One end of the telescopic rod is hinged to the rotating shaft, and the other end of the telescopic rod is connected to the universal joint and is used to move toward or away from one end of the telescopic rod.

It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0030] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0031] An embodiment of this utility model provides a smart electric cotton quilt rolling device for greenhouses, comprising: a sliding track 1, which is configured to be installed on the top edge of a greenhouse 2 and extends along the edge of the greenhouse 2 to both ends of the greenhouse 2 in the horizontal direction; a roller 3, which is slidably installed on the sliding track 1 and extends in a direction perpendicular to the sliding track 1, the roller 3 being wound around one end of a cotton quilt 4 covering the greenhouse 2, and the other end of the cotton quilt 4 being connected to a fixed roller 5 fixedly connected to the greenhouse 2; a rotary drive mechanism 6, which is drivenly connected to the roller 3 and slidably installed on the sliding track 1; multiple limiters 7, which are spaced apart on the sliding track 1 to contact the rotary drive mechanism 6; and a networked remote control forward and reverse switch 8, which is installed on the greenhouse 2 and electrically connected to the rotary drive mechanism 6 and the limiters 7 respectively via cables.

[0032] Specifically, the rotary drive mechanism 6 is driven by a rotary motor or a servo motor to achieve rotation. The limit switch 7 can be a mechanical limit switch, such as a push-button limit switch, or a non-contact limit switch, such as a magnetic limit switch. There are two limit switches 7, one set near the ground of the sliding track 1 and the other set in the middle of the sliding track 1.

[0033] In this embodiment, as Figure 1As shown, a greenhouse intelligent electric quilt rolling device is constructed by setting up a sliding track 1, a roller 3, a quilt 4, a fixed roller 5, a rotary drive mechanism 6, a limit switch 7, and a networked remote control forward / reverse switch 8. The sliding track 1 is configured to be installed on the top edge of the greenhouse 2 and extends along the edge of the greenhouse 2 to both ends in the horizontal direction. This allows the roller 3 and the rotary drive mechanism 6 to slide along the sliding track 1 from one end of the greenhouse 2 to the other. The rotary drive mechanism 6 is driven by the roller 3, which extends perpendicular to the sliding track 1 and wraps around one end of the quilt 4 covering the greenhouse 2. The other end of the quilt 4 is connected to the fixed roller 5, which is fixedly connected to the greenhouse 2. The rotary drive mechanism is controlled by the networked remote control forward / reverse switch 8. When the drive roller 3 rotates, the fixed roller 5 fixes the other end of the quilt 4. When the roller 3 rotates and curls one end of the quilt 4, the reverse force of the rotational force pulls both the roller 3 and the rotary drive mechanism 6 to slide along the sliding track 1, realizing the automatic opening of the quilt 4 and effectively improving the ease of operation. Based on this, multiple limiters 7 are installed at intervals on the sliding track 1. The rotary drive mechanism 6 and the limiters 7 can be aligned to disconnect. The networked remote control forward / reverse switch 8 is installed on the greenhouse 2 and electrically connected to the rotary drive mechanism 6 and the limiters 7 via cables. With this setup, when the rotary drive mechanism 6 aligns with the limiters 7 on the sliding track 1, the rotary drive mechanism 6 is de-energized, allowing the quilt 4 to curl to a preset position. When the networked remote control forward / reverse switch 8 controls the rotary drive mechanism 6 to reverse, the rotary drive mechanism 6 contacts the limiters 7 near the ground on the sliding track 1, causing the quilt 4 to extend to the set position and stop. This allows the cotton quilt 4 to be released, covering the greenhouse 2, thus achieving automated covering of the cotton quilt 4 and further improving operational convenience. In addition, the network-connected remote control forward and reverse switch 8 can be network-controlled, facilitating remote connection and operation by operators, further enhancing operational convenience.

[0034] Optionally, the rotary drive mechanism 6 includes a rotary drive assembly 61 and a coupling 62. The rotary drive assembly 61 is slidably mounted on the sliding track 1 and is drivenly connected to the roller shaft 3 through the coupling 62. The coupling 62 has a built-in torque limiter.

[0035] Specifically, the rotary drive assembly 61 can achieve rotary drive through a rotary motor or a servo motor.

[0036] In this optional embodiment, such as Figure 1 and Figure 2As shown, a rotary drive mechanism 6 is formed by a rotary drive assembly 61 and a coupling 62. The rotary drive assembly 61 is slidably mounted on the sliding track 1 and is drivenly connected to the roller shaft 3 through the coupling 62. This allows the rotary drive assembly 61 to slide along with the roller shaft 3, while the coupling 62 ensures the connection stability between the rotary drive assembly 61 and the roller shaft 3. The coupling 62 has a built-in torque limiter. During the process of the roller shaft 3 rolling the quilt 4, if the quilt 4 is difficult to roll due to freezing or other unexpected circumstances, resulting in a large rotary drive force required by the roller shaft 3, the torque limiter can disconnect the connection between the roller shaft 3 and the rotary drive assembly 61 when the rotary drive force exceeds a preset threshold. This prevents damage to the rotary drive assembly 61 and the roller shaft 3 caused by excessive rotary drive force and ensures operational stability.

[0037] Optionally, the rotary drive assembly 61 includes a protective shell, a rotary drive component, and a reducer. The protective shell is a hollow structure and is slidably mounted on the sliding track 1. The rotary drive component and the reducer are both installed inside the protective shell. The rotary drive component is driven and connected through the reducer and the coupling 62.

[0038] Specifically, the rotary drive component is a rotary motor or a servo motor.

[0039] In this optional embodiment, a rotary drive assembly 61 is formed by a protective shell, a rotary drive component, and a reducer. The protective shell is a hollow structure, and the rotary drive component and the reducer are installed inside the protective shell, thereby protecting the rotary drive component and the reducer and improving working stability. The protective shell is slidably installed on the sliding track 1, and the rotary drive component is driven and connected through the reducer and the coupling 62. This allows the protective shell to slide with the roller shaft 3, ensuring the movement stability of the rotary drive mechanism 6. The rotary drive component can be reduced to a preset rotational speed by the reducer, ensuring a stable output of the rotary drive force and avoiding excessive output of the rotary drive force from affecting the structural stability of the roller shaft 3 and the rolling and unrolling stability of the quilt 4.

[0040] Optionally, the sliding track 1 includes a first track 11, which is located on one side of the greenhouse 2 along the extension direction of the roller shaft 3 and extends beyond the edge of the greenhouse 2 to form a finial. A protective shell is placed on the finial, and a networked remote control forward and reverse switch 8 is located below the finial.

[0041] In this optional embodiment, such as Figure 1As shown, the sliding track 1 is provided with a first track 11, which is located on one side of the greenhouse 2 along the extension direction of the roller shaft 3 and extends beyond the edge of the greenhouse 2 to form a burr. The protective shell is placed on the burr. With this arrangement, the burr can stably support the protective shell when it moves with the roller shaft 3, so that the protective shell can slide stably along the first track 11. At the same time, the network remote control forward and reverse switch 8 is located below the burr. In this way, the burr can protect the network remote control forward and reverse switch 8, avoid adverse effects on the network remote control forward and reverse switch 8 in rainy or snowy weather, and ensure the stability of operation.

[0042] Optionally, the sliding track 1 includes a second track 12, which is disposed on one side of the greenhouse 2 along the extension direction of the roller shaft 3. A first sliding opening 121 is provided through the second track 12 along the extension direction of the roller shaft 3. The rotary drive mechanism 6 also includes a roller 63, which is rotatably connected to the rotary drive assembly 61 and placed inside the first sliding opening 121. The roller 63 is used to roll along the inner wall of the first sliding opening 121.

[0043] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the sliding track 1 is provided with a second track 12, which is located on one side of the greenhouse 2 along the extension direction of the roller shaft 3. At the same time, a first sliding opening 121 is provided through the second track 12 along the extension direction of the roller shaft 3. Correspondingly, the rotary drive mechanism 6 is also provided with a roller 63, which is rotatably connected to the rotary drive assembly 61 and placed inside the first sliding opening 121. With this arrangement, when the rotary drive assembly 61 slides along the sliding track 1 with the movement of the roller shaft 3, the roller 63 can roll along the inner wall of the first sliding opening 121, changing sliding to rolling, reducing friction, and making the sliding of the rotary drive assembly 61 more stable.

[0044] Optionally, the sliding track 1 includes a third track 13, which has two sections and is respectively located on both sides of the greenhouse 2 along the extension direction of the roller shaft 3. A second sliding port 131 is provided through the third track 13 along the extension direction of the roller shaft 3. The coupling 62 passes through the second sliding port 131 located on one side of the greenhouse 2 along the extension direction of the roller shaft 3, and the end of the roller shaft 3 away from the coupling 62 passes through the second sliding port 131 located on the other side of the greenhouse 2 along the extension direction of the roller shaft 3.

[0045] In this optional embodiment, such as Figure 1 and Figure 2As shown, the sliding track 1 is provided with a third track 13, wherein there are two third tracks 13, which are respectively set on both sides of the greenhouse 2 along the extension direction of the roller shaft 3. At the same time, a second sliding port 131 is provided through the third track 13 along the extension direction of the roller shaft 3. The coupling 62 passes through the second sliding port 131 located on one side of the greenhouse 2 along the extension direction of the roller shaft 3, while the end of the roller shaft 3 away from the coupling 62 passes through the second sliding port 131 located on the other side of the greenhouse 2 along the extension direction of the roller shaft 3. Thus, when the roller shaft 3 slides along the sliding track 1, the ends of the coupling 62 and the roller shaft 3 cooperate and move stably in the second sliding ports 131 on the two third tracks 13, effectively improving the sliding stability of the roller shaft 3, so that the quilt 4 can be rolled and spread more stably.

[0046] Optionally, the greenhouse intelligent electric cotton quilt rolling equipment also includes a pushing mechanism 9, which includes a swing component 91 and a universal joint 92. The swing component 91 is distributed at intervals with the greenhouse 2 along the extension direction of the roller shaft 3. The swing component 91 is connected to the rotary drive mechanism 6 through the universal joint 92 and is used to swing back and forth along the extension trajectory of the sliding track 1.

[0047] Specifically, the swing component 91 can be a pendulum or a servo motor.

[0048] In this optional embodiment, in order to improve the movement stability of the rotary drive mechanism 6, such as Figure 1 and Figure 2 As shown, the intelligent electric cotton quilt rolling equipment for greenhouses is also equipped with a pushing mechanism 9, which consists of a swing component 91 and a universal joint 92. The swing component 91 and the greenhouse 2 are distributed at intervals along the extension direction of the roller shaft 3. At the same time, the swing component 91 is connected to the rotary drive mechanism 6 through the universal joint 92 and can swing back and forth along the extension trajectory of the sliding track 1. In this way, the structural characteristics of the universal joint 92 can be used to change the relative rotation axis between the universal joint 92 and the rotary drive mechanism 6 at any time. This allows the swing component 91 to stably support the rotary drive mechanism 6 through the universal joint 92 while avoiding obstructing the movement of the rotary drive mechanism 6.

[0049] Optionally, the swing assembly 91 includes a support base 911, a rotating shaft 912, and a telescopic rod 913. The support base 911 and the greenhouse 2 are spaced apart along the extension direction of the roller shaft 3. The rotating shaft 912 is rotatably mounted on the support base 911 and extends horizontally toward the greenhouse 2. One end of the telescopic rod 913 is hinged to the rotating shaft 912, and the other end of the telescopic rod 913 is connected to a universal joint 92 and is used to move toward or away from one end of the telescopic rod 913.

[0050] In this optional embodiment, such as Figure 1 and Figure 2As shown, a swing assembly 91 is formed by a support base 911, a rotating shaft 912, and a telescopic rod 913. The support base 911 and the greenhouse 2 are spaced apart along the extension direction of the roller shaft 3. The rotating shaft 912 is rotatably mounted on the support base 911 and extends horizontally toward the greenhouse 2. One end of the telescopic rod 913 is hinged to the rotating shaft 912, and the other end of the telescopic rod 913 is connected to a universal joint 92, allowing it to move toward or away from the end of the telescopic rod 913. With this configuration, when the rotary drive mechanism 6 moves with the roller shaft 3, the rotating shaft 912 rotates under the drive of the universal joint 92 and the telescopic rod 913. At the same time, as the rotary drive mechanism 6 moves, the telescopic rod 913 extends and retracts. The universal joint 92 maintains stable support for the rotary drive mechanism 6 at all times, ensuring the stability of the rotary drive mechanism 6's movement.

[0051] Optionally, the cable includes wires, corrugated pipes, and sleeves. The networked remote control forward / reverse switch 8 is electrically connected to the rotary drive mechanism 6 and the limit switch 7 via wires, respectively. The corrugated pipe is fitted onto the wires, and the sleeve is fitted onto the corrugated pipes. And / or, it also includes a power module, which is electrically connected to the networked remote control forward / reverse switch 8 and includes a fixed power supply and a photovoltaic power supply.

[0052] In this optional embodiment, a cable is provided consisting of wires, corrugated pipes, and sheaths. The networked remote control forward and reverse switch 8 is electrically connected to the rotary drive mechanism 6 and the limit switch 7 via wires to ensure the stability of the circuit connection. The corrugated pipe is fitted onto the wires to improve the structural strength of the cable and prevent animals from biting it, which would affect the stability of the cable's use. The sheath is fitted onto the corrugated pipes to effectively reduce the impact of ultraviolet rays on the cable and improve its service life.

[0053] In this optional embodiment or other optional embodiments of the present invention, a power module is also provided. The power module is electrically connected to the networked remote control forward and reverse switch 8 to ensure a stable power supply. At the same time, the power module includes a fixed power supply and a photovoltaic power supply. It can not only ensure the daily power supply through the fixed power supply, but also use solar energy to charge the fixed power supply or store the power through the photovoltaic power supply, effectively improving the stability of the power supply.

[0054] Optionally, the network-connected remote control forward and reverse switch 8 includes an overload protection circuit, a communication unit, a forward and reverse control circuit, and a signal processing module. The signal processing module is electrically connected to the communication unit and the overload protection circuit, respectively. The overload protection circuit is electrically connected to the forward and reverse control circuit, and the signal processing module is electrically connected to the limit switch 7 via a cable.

[0055] Specifically, the communication unit is a 4G IoT card communication module; the signal processing module includes a signal processing chip, which is connected to the circuit on the circuit board by soldering or plugging through pins.

[0056] In this optional embodiment, an overload protection circuit, a communication unit, a forward / reverse control circuit, and a signal processing module are provided to form a networked remote control forward / reverse switch 8. The signal processing module is electrically connected to the communication unit and the overload protection circuit to ensure the remote communication capability and operational stability of the networked remote control forward / reverse switch 8. At the same time, the overload protection circuit is electrically connected to the forward / reverse control circuit, and the signal processing module is electrically connected to the rotary drive mechanism 6 and the limit switch 7 via cables, thereby enabling effective control of the forward and reverse rotation of the rotary drive mechanism 6 and improving the ease of operation.
