Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and in particular to a support device for a greenhouse curtain rolling machine. Background Technology

[0002] Greenhouses, as an important component of modern agriculture, enable off-season cultivation and high-efficiency production of crops by creating suitable artificial environments. In the daily operation of greenhouses, the rolling up and down of coverings such as insulation blankets and shade nets is a crucial step in regulating light, temperature, and humidity inside the greenhouse. Traditional manual rolling up and down methods are labor-intensive, inefficient, and unable to respond promptly to environmental changes. Therefore, electric rolling shutter machines have emerged and have become standard equipment in modern greenhouses.

[0003] Electric rolling shutter machines typically consist of a motor, a reducer, a roller, and a support system. Their working principle is as follows: the motor drives the reducer, which in turn rotates the roller, thus rolling up or unrolling the insulation blanket or shade netting covering the greenhouse roof. The support system is the core load-bearing and stabilizing structure of the entire system. It is responsible for stably transmitting and securing the enormous tensile and torque generated by the rolling shutter machine (especially the weight of the motor and roller) and the covering material during the rolling and unrolling process to the greenhouse frame.

[0004] Currently, to adapt to the installation needs of greenhouses of different specifications, the common support devices for rolling shutter machines on the market mostly adopt a structure of two adjustable-length telescopic rods, which are connected to the greenhouse frame and roller shaft through a rotating seat in order to achieve flexible installation. However, this seemingly flexible structure has exposed its inherent mechanical defects in practical applications: due to the lack of effective lateral connection between the telescopic rods, the overall structure cannot form a stable force-bearing system, resulting in serious deficiencies in its bending and torsional resistance. Therefore, when subjected to the huge unidirectional tension generated during the rolling shutter operation or encountering lateral loads such as strong winds, the support device is prone to significant elastic deformation or even overall swaying, which not only affects the stability of the rolling shutter but also poses a potential threat to the safety of the entire system. In addition, after the structure is installed, the adjustment range of its key parameters such as height and angle is extremely limited, often only allowing for rough adjustments, making it difficult to accurately center and level, resulting in poor adaptability to greenhouse construction errors and failing to guarantee the long-term stable and reliable operation of the rolling shutter machine. Utility Model Content

[0005] One objective of this invention is to provide a support device for greenhouse curtain rolling machines. This invention addresses the issues raised in the background above, where current greenhouse curtain rolling machine support devices mostly employ a structure of two telescopic rods with a rotating base. While this aims for installation flexibility, it suffers from inherent mechanical defects. Due to the lack of effective constraint between the telescopic rods, the overall bending and torsional resistance is poor, making it prone to deformation and swaying under curtain tension or wind load, posing safety hazards. Furthermore, this structure is inconvenient to adjust after installation, making precise centering and leveling difficult, resulting in poor adaptability to greenhouse construction errors and affecting the stability of equipment operation.

[0006] A greenhouse curtain rolling machine support device according to an embodiment of the present utility model includes: A support mechanism for installing a roller shutter machine, comprising a main telescopic rod, a secondary telescopic rod, and a horizontal shaft; The diagonal bracing mechanism is installed on the outside of the support mechanism to form a triangular structure. It includes a support cylinder and a support rod that is movably set at its end through a threaded sleeve. It also includes a rotating seat fixed above the outside of the main telescopic rod and a fixed seat installed on the ground. A ball is fixedly set at the bottom end of the support cylinder and a ball seat is fixedly set at the top of the fixed seat. An adjustment mechanism is installed inside the horizontal shaft. It includes a base supported on the outside of the horizontal shaft and movable plates that move symmetrically at both ends of the horizontal shaft via springs. A positioning pin is fixedly installed on one side of the movable plate, penetrating the interior of the horizontal shaft. A positioning hole is opened inside the base. A fixing ring is fixedly installed on the other side of the movable plate. The positioning pin is connected to the fixing ring through a toggle assembly to achieve telescopic movement.

[0007] Preferably, the auxiliary telescopic rod is rotatably mounted on top of the main telescopic rod via a universal joint, a horizontal shaft is welded to the bottom of the main telescopic rod, and a mounting plate is welded to the movable end of the auxiliary telescopic rod.

[0008] Preferably, a knob is installed on the outside of the threaded sleeve.

[0009] Preferably, the support rod and the rotating seat are rotatably connected, and the ball is located inside the ball seat and is movable.

[0010] Preferably, the main telescopic rod moves within a transverse groove at the top of the base.

[0011] Preferably, each positioning hole is provided with a plurality of holes, and the positioning pins are matched with the positioning holes.

[0012] Preferably, the actuating assembly includes a lever that moves within the main telescopic rod via a guide rod, and a steel wire rope fixed between two fixed rings, wherein the steel wire rope and the lever are fixedly disposed together.

[0013] Preferably, the wire rope has a Y-shaped structure.

[0014] The beneficial effects of this utility model are: 1. This utility model effectively avoids the problems of poor bending and torsion resistance of the support device and easy deformation and swaying under wind load and roller shutter tension by setting the diagonal bracing mechanism. In use, the diagonal bracing mechanism achieves fine length adjustment by connecting the support cylinder and the support rod through the threaded sleeve. The ball at the bottom is movably set in the ball seat of the fixed seat, and the top is connected to the upper outer side of the main telescopic rod through the rotating seat, forming a multi-directional adjustable triangular stable structure. When the roller shutter operation generates unidirectional tension or encounters strong wind, the diagonal bracing mechanism can effectively decompose and transfer the lateral load to the ground. The stability of the triangular structure significantly enhances the bending and torsion resistance of the support device. At the same time, the cooperation between the ball and the ball seat and the rotational connection between the support rod and the rotating seat allow the structure to make small adaptive angle adjustments when under force, further buffering the impact load, thereby effectively preventing the deformation and swaying of the support device, ensuring the stability of the roller shutter operation and the safety of the system. 2. This utility model effectively avoids the problems of inconvenient adjustment and poor adaptability of the support device after installation by setting an adjustable mechanism. In use, the adjustment mechanism forms a locking system through the symmetrically arranged movable plates, springs and positioning pins inside the horizontal axis. When it is necessary to adjust the position of the support mechanism, the paddle in the toggle assembly moves upward along the guide rod, pulling the Y-shaped steel wire rope to simultaneously pull the two fixed rings on both sides, so that the movable plate overcomes the spring resistance and drives the positioning pin to retract from the positioning hole of the base. At this time, the main telescopic rod can slide freely in the horizontal groove of the base. After the adjustment is in place, the paddle is released, and the spring pushes the positioning pin to re-insert into the corresponding positioning hole to achieve precise fixation. This allows the support device to still be adjusted after installation, thereby improving the adaptability and operational reliability of the device. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] refer to Figures 1-4 A support device for a greenhouse curtain rolling machine, comprising: Support mechanism 1 is used to install the roller shutter machine, including a main telescopic rod 101, a secondary telescopic rod 104 and a horizontal shaft 102. The secondary telescopic rod 104 is rotatably mounted on the top of the main telescopic rod 101 via a universal seat 103. The horizontal shaft 102 is welded to the bottom of the main telescopic rod 101. The movable end of the secondary telescopic rod 104 is welded with a mounting plate 105. The diagonal bracing mechanism 2 is installed on the outside of the support mechanism 1 to form a triangular structure. It includes a support cylinder 201 and a support rod 202 that is movably provided at its end through a threaded sleeve 203. It also includes a rotating seat 204 fixed on the upper outside of the main telescopic rod 101 and a fixed seat 207 installed on the ground. A ball 205 is fixedly provided at the bottom end of the support cylinder 201 and a ball seat 206 is fixedly provided at the top of the fixed seat 207. In use, the diagonal bracing mechanism 2 achieves fine-tuning of its length by connecting the support cylinder 201 and the support rod 202 via the threaded sleeve 203. The ball 205 at its bottom is movably set in the ball seat 206 of the fixed seat 207, and the top is connected to the upper outer side of the main telescopic rod 101 via the rotating seat 204, forming a multi-directionally adjustable triangular stable structure. When the roller shutter machine generates unidirectional tension or encounters strong winds, the diagonal bracing mechanism 2 can effectively decompose and transfer the lateral load to the ground. The stability of the triangular structure significantly enhances the bending and torsional resistance of the support mechanism 1. At the same time, the cooperation between the ball 205 and the ball seat 206 and the rotational connection between the support rod 202 and the rotating seat 204 allow the structure to make slight adaptive angle adjustments when under stress, further buffering the impact load. Adjustment mechanism 3 is installed inside the horizontal shaft 102. It includes a base 301 supported on the outside of the horizontal shaft 102 and a movable plate 303 that moves symmetrically at both ends inside the horizontal shaft 102 via a spring 305. A positioning pin 304 is fixedly provided on one side of the movable plate 303, penetrating the interior of the horizontal shaft 102. A positioning hole 302 is provided inside the base 301. A fixing ring 306 is fixedly provided on the other side of the movable plate. The positioning pin 304 is connected to the fixing ring 306 through a toggle assembly to achieve telescopic movement. The actuation assembly includes a lever 308 that is movable inside the main telescopic rod 101 via a guide rod 309, and a wire rope 307 fixed between two fixed rings 306. The wire rope 307 and the lever 308 are fixedly disposed together. In use, the adjustment mechanism 3 forms a locking system through the movable plate 303, spring 305, and positioning pin 304 symmetrically arranged inside the horizontal shaft 102. When the position of the support mechanism 1 needs to be adjusted, the paddle 308 in the actuation assembly moves upward along the guide rod 309, pulling the Y-shaped steel wire rope 307 to simultaneously pull the two fixed rings 306, so that the movable plate 303 overcomes the resistance of the spring 305 and drives the positioning pin 304 to retract from the positioning hole 302 of the base 301. At this time, the main telescopic rod 101 can slide freely in the horizontal groove of the base 301. After the adjustment is in place, the paddle 308 is released, and the spring 305 pushes the positioning pin 304 to re-insert into the corresponding positioning hole 302 to achieve precise fixation, so that the support device can still be adjusted after installation.

[0018] Example 1: A knob is installed on the outside of the threaded sleeve 203. The operator can easily drive the threaded sleeve to rotate by rotating the knob, thereby precisely adjusting the length of the support rod 202 screwed into the support cylinder 201 to adapt to different installation distances and apply preload. The support rod 202 and the rotating seat 204 are rotatably connected. The ball 205 is located inside the ball seat 206 and is movable. This universal joint-type ball joint structure allows the inclined bracing mechanism to flexibly adapt to angle changes caused by thermal expansion and contraction or slight ground settlement while transmitting the main support force, avoiding internal stress caused by rigid connection. The main telescopic rod 101 is located in the transverse groove at the top of the base 301 and is movable.

[0019] Example 2: Several positioning holes 302 are provided, and positioning pins 304 are matched with positioning holes 302. These positioning holes are precisely matched with positioning pins 304 on movable plates 303, providing multiple discrete and reliable locking positions for the support mechanism, ensuring the stability of the adjusted structure. The wire rope 307 has a Y-shaped structure, with its two forked ends fixedly connected to two fixed rings 306 respectively, and the converging end connected to the lever 308. When the operator moves the lever 308, the Y-shaped wire rope 307 can evenly transmit the tension to the fixed rings 306 at both ends, ensuring that the two movable plates 303 and their positioning pins 304 retract or extend synchronously and symmetrically. This realizes the function of controlling the unlocking and locking of both sides with a single point operation. The structure is ingenious, the operation is efficient, and the ease of use and adjustment efficiency of the device are significantly improved.

[0020] Working Principle: First, during the installation phase, the base 301 is fixed to the ground. The main telescopic rod 101 of the support mechanism 1 is placed in the transverse groove of the base 301. The secondary telescopic rod 104 at its top is connected through the universal joint 103. The roller shutter is installed through the mounting plate 105 at the end of the secondary telescopic rod 104. Next, the diagonal bracing mechanism 2 is installed. One end of the diagonal bracing mechanism 2 is connected to the main telescopic rod 101 through the rotating seat 204. The other end is adjusted to a suitable length through the support rod 202, support cylinder 201, and threaded sleeve 203. The ball 205 at the bottom is embedded in the ball seat 206 of the fixed seat 207 on the ground, forming a stable triangular support structure. When the roller shutter generates tension during operation or encounters strong winds, the diagonal bracing mechanism 2 effectively decomposes and transfers the lateral load to the ground. The stability of the triangular structure significantly enhances the bending and torsional resistance of the support mechanism 1. The force, along with the cooperation and rotational connection between the ball 205 and the ball seat 206, allows for slight adaptive angle adjustments to buffer impacts. When fine-tuning of the support device's position is required, the operator moves the lever 308 inside the main telescopic rod 101. The lever 308 moves upward along the guide rod 309, pulling the Y-shaped steel wire rope 307. The steel wire rope 307 simultaneously pulls the two fixed rings 306, causing the movable plate 303 to overcome the elastic force of the spring 305 and drive the positioning pin 304 to retract from the positioning hole 302 of the base 301. At this time, the main telescopic rod 101 can slide freely in the transverse groove of the base 301 to adjust its position. After adjustment, the lever 308 is released, the spring 305 resets and pushes the movable plate 303, causing the positioning pin 304 to re-insert into the corresponding positioning hole 302, completing precise fixing. This achieves convenient adjustment and reliable locking after installation.
