Description

Technical Field

[0001] This utility model belongs to the field of greenhouse technology, and in particular to a greenhouse insulation blanket take-up and take-down device. Background Technology

[0002] Greenhouses typically use insulation blankets for auxiliary insulation. During the use and storage of greenhouse insulation blankets, a winding and unwinding device is required. However, existing winding and unwinding devices can pull on the greenhouse insulation blankets during the winding and unwinding process, causing them to stretch and become damaged.

[0003] In related technologies, a search revealed a Chinese patent document (authorization announcement number CN214709103U) entitled "A Greenhouse Insulation Blanket Retraction and Unloading Device," which includes a greenhouse body, a retraction and unloading component, a leveling component, and an electrical control cabinet. In this utility model, the leveling component is designed so that when the insulation blanket body is retracted or unloaded, the leveling motor drives the rotating plate and connecting rod to move in the direction of movement of the insulation blanket body. The connecting rod drives the fixed rod to move, and the electrical control cabinet controls the moving speed of the fixed rod to be consistent with the moving speed of the insulation blanket body. This facilitates the leveling of the insulation blanket body during retraction and unloading, avoids folding of the insulation blanket body, and improves the working efficiency of the retraction and unloading device. However, this device does not consider that the insulation blanket is easily pulled and damaged during the retraction and unloading process. Utility Model Content

[0004] The purpose of this utility model is to provide a device for taking in and taking out greenhouse insulation blankets, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse insulation blanket deployment and retraction device, comprising:

[0006] The main body of the insulation blanket for greenhouses has several nylon webbings on its upper and lower parts. Connecting rods are connected to both ends of the insulation blanket. Several pairs of insertion slots are opened on the sides of the connecting rods. Each pair of insertion slots is arranged vertically. A movable plate is slidably connected to the inner wall of the insertion slot of the connecting rod. Limiting plates are slidably connected to both sides of the movable plate. The centrifugal side of the two limiting plates is connected to the connecting rod. A rubber anti-slip plate for squeezing the nylon webbing is glued to the bottom surface of the movable plate. A clamping block is embedded in the top surface of the movable plate. A clamping bolt is set on the side of the clamping block away from the anti-slip plate. Several clamping bolts are threadedly connected to the connecting rod.

[0007] Two mounting brackets are L-shaped, with fixed bearings embedded in the sides of the mounting brackets. The inner rings of the fixed bearings are interference-fitted with rotating blocks, and the adjacent sides of the two rotating blocks are connected to one of the connecting rods.

[0008] Preferably, the anti-slip plate is slidably connected to two limiting plates on both sides, and the end face of one of the rotating blocks is connected to the output shaft of a rotary motor via a coupling.

[0009] Preferably, the fixed end of the rotary motor is connected and fixed to the mounting bracket by bolts, and the adjacent sides of the two mounting brackets are in rotational frictional contact with the connecting rod.

[0010] Preferably, both mounting brackets are provided with support plates at their lower parts, and the top surface of the support plates is rotatably connected to a hollow telescopic outer plate via a pin.

[0011] Preferably, the telescopic outer panel is embedded in a sliding connection with a movable plate, and the top surface of the movable plate is connected to a telescopic inner panel.

[0012] Preferably, the top surface of the telescopic outer panel is slidably connected to the telescopic inner panel, and the top surface of the telescopic inner panel is fixedly connected to the mounting frame.

[0013] Preferably, an electric push rod is installed on the centrifugal side of both telescopic outer plates, and the moving end of the electric push rod is connected and fixed to the mounting frame.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This greenhouse insulation blanket retraction device addresses the issue of greenhouse insulation blankets requiring retraction. Existing retraction devices easily stretch the insulation blankets during retraction and unretraction, causing damage. This device addresses this by incorporating several nylon webbing strips to protect the insulation blankets. Each pair of vertically arranged nylon webbing strips extends into the insertion slots of two different connecting rods. The two vertically arranged nylon webbing strips are located at the top and bottom of the insulation blanket body, respectively. This allows the clamping bolts to move along the threaded path of the connecting rods. The connection between the clamping block and the moving plate ensures that the anti-slip plate presses against the nylon webbing strips, protecting the insulation blanket body during retraction and unretraction.

[0016] The greenhouse insulation blanket retraction device has a rough surface on the side of the clamping block away from the anti-slip plate. When the clamping bolt and the clamping block are clamped together, the position of the clamping block and the clamping bolt is fixed under the action of frictional resistance. During long-term use, the surface of the clamping block will be worn flat, causing the nylon webbing to fall off. The clamping block and the clamping bolt can be easily disassembled, improving the fixing effect of the nylon webbing.

[0017] This greenhouse insulation blanket winding and unwinding device uses a rotary motor whose output shaft rotates, driving a rotating block to rotate, which in turn drives a connecting rod to rotate, thus winding and unwinding the insulation blanket. Another connecting rod is located at the top of the greenhouse, allowing the connecting rod for winding the insulation blanket to rotate and move during the winding and unwinding process. Two electric push rods provide power, adjusting the rotation radius of the connecting rod during transmission to ensure full and even contact between the insulation blanket and the greenhouse, enhancing the winding and unwinding effect of the device. A movable plate moves along the inner cavity of the telescopic outer plate, improving the relative movement stability between the telescopic inner and outer plates and enhancing the structural stability of the device's components.

Detailed Implementation

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] Please see Figures 1 to 5 A device for taking in and releasing greenhouse insulation blankets, in this embodiment, includes:

[0030] The main body 8 of the greenhouse insulation blanket has several nylon webbing 7 on its upper and lower parts. Connecting rods 1 are connected to both ends of the main body 8. The main body 8 and the connecting rods 1 are connected by ropes. Several pairs of insertion slots are opened on the side of the connecting rods 1, each pair arranged vertically. Each nylon webbing 7 extends into two different insertion slots of the connecting rods 1 at both ends. The vertically arranged nylon webbing 7 extends into the upper and lower insertion slots of the connecting rods 1 respectively. A movable plate 2 is slidably connected to the inner wall of the insertion slot of the connecting rod 1. Limiting plates 3 are embedded and slidably connected to both sides of the movable plate 2. The centrifugal side of each of the two limiting plates 3 is connected to the connecting rod 1. A rubber anti-slip plate 4 is adhered to the bottom surface of the movable plate 2 to compress the nylon webbing 7. When the nylon webbing 7 extends into the insertion slot of the connecting rod 1... When in the groove, the anti-slip plate 4 and the connecting rod 1 work together to clamp and fix the nylon webbing 7. The top surface of the moving plate 2 is embedded with a clamping block 5. The side of the clamping block 5 away from the anti-slip plate 4 is provided with a clamping bolt 6. The side of the clamping block 5 and the clamping bolt 6 adjacent to each other are rough. The top surface of the moving plate 2 has two inclined grooves, and the two grooves are connected to the inner cavity of the moving plate 2, which facilitates manual disassembly of the clamping block 5. This prevents the rough surface of the clamping block 5 from being worn flat during long-term use, which would cause the clamping bolt 6 and the clamping block 5 to loosen and thus cause the nylon webbing 7 to fall off. The ease of use of the device can be improved by easily replacing the clamping block 5 and the clamping bolt 6. Several clamping bolts 6 are threaded to the connecting rod 1. The number of clamping bolts 6 is the same as the number of insertion slots of the connecting rod 1. Each nylon webbing 7 corresponds to two different insertion slots opened on the connecting rod 1.

[0031] Two mounting brackets 9 are L-shaped and arranged centrifugally. Fixed bearings 10 are embedded and fixedly connected to the sides of the mounting brackets 9. Rotating blocks 11 are interference-fitted to the inner rings of the fixed bearings 10. The two rotating blocks 11 are connected to one of the connecting rods 1 on their adjacent sides.

[0032] The anti-slip plate 4 is slidably connected to the two limiting plates 3 on both sides. One of the rotating blocks 11 has its end face connected to the output shaft of a rotary motor 12 via a coupling. The fixed end of the rotary motor 12 is fixed to the mounting bracket 9 via bolts. When the output shaft of the rotary motor 12 rotates, the connecting rod 1 rotates under the connection of the rotating block 11, thus enabling the connecting rod 1 to wind or unwind the insulation blanket body 8. Simultaneously, it winds or unwinds several nylon webbing strips 7, providing support and protection for the insulation blanket body 8 and preventing it from being stretched and damaged. The adjacent sides of the two mounting brackets 9 are in rotational friction contact with the connecting rod 1. Each part is equipped with a support plate 13. The two support plates 13 are fixed to the ground to fix the position of the device. The top surface of the support plate 13 is rotatably connected to a hollow telescopic outer plate 14 through a pin. A movable plate 15 is slidably connected to the telescopic outer plate 14. The top surface of the movable plate 15 is connected to a telescopic inner plate 16. The top surface of the telescopic outer plate 14 and the telescopic inner plate 16 are slidably connected. The top surface of the telescopic inner plate 16 is connected and fixed to the mounting frame 9. An electric push rod 17 is installed on the centrifugal side of each of the two telescopic outer plates 14. The fixed end of the electric push rod 17 is connected and fixed to the telescopic outer plate 14 through bolts. The moving end of the electric push rod 17 is connected and fixed to the mounting frame 9.

[0033] To protect the insulation blanket body 8, several nylon webbing strips 7 extend into several insertion slots opened in two different connecting rods 1 at both ends. The several nylon webbing strips 7 are located at the upper and lower parts of the insulation blanket body 8, and the length of the nylon webbing strips 7 located on the adjacent sides of the two connecting rods 1 is the same as the length of the insulation blanket body 8. The tightening bolt 6 moves down along the threaded path of the connecting rod 1, and the threaded part of the tightening bolt 6 pushes the tightening block 5 to move vertically. The moving plate 2 and the anti-slip plate 4 move down along the path of the two limiting plates 3 toward the nylon webbing strips 7. The anti-slip plate 4 and the connecting rod 1 work together to fix the nylon webbing strips 7 and prevent the nylon webbing strips 7 from falling off. When the connecting rod 1 rolls up or unrolls the insulation blanket body 8, the several nylon webbing strips 7 are rolled up or unrolled simultaneously, realizing the protective function of the several nylon webbing strips 7 for the insulation blanket body 8, preventing the insulation blanket body 8 from being stretched and elongated during the rolling up or unrolling process, causing damage to the insulation blanket body 8, and extending the service life of the insulation blanket body 8.

[0034] To accommodate greenhouses with different curvatures, a connecting rod 1 connected to two rotating blocks 11 is located at the bottom, and another connecting rod 1 is located at the top of the greenhouse and fixed to it. When the output shaft of the rotary motor 12 rotates, the connecting rod 1, connected to the rotating blocks 11, causes the insulation blanket body 8 to be rolled up or unrolled during rotation. Two electric push rods 17 provide power, and the circumferential moving radius of the connecting rod 1 is adjusted during transmission to ensure that the rolled-up or unrolled insulation blanket body 8 is in full contact with the top of the greenhouse, preventing deviation of the insulation blanket body 8 during unrolling and preventing the connecting rod 1 from not evenly rolling up the insulation blanket body 8 during winding. The movable plate 15 moves along the inner cavity of the telescopic outer plate 14, enhancing the relative movement stability of the telescopic inner plate 16 and the telescopic outer plate 14 during transmission and enhancing the position adjustment stability of the connecting rod 1. The moving ends of the two electric push rods 17 are controlled by a controller, which controls the moving ends of the two electric push rods 17 to move synchronously in the same direction.

[0035] The rotary motor 12 and the electric push rod 17 are both existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0036] Working principle

[0037] When using this greenhouse insulation blanket retraction device, the user extends several nylon webbing 7 into several insertion slots of two different connecting rods 1 at both ends, rotates several clamping bolts 6, and under the connection of clamping blocks 5, moves the moving plate 2 and the anti-slip plate 4 along the path of the limiting plate 3 toward the nylon webbing 7, so that the anti-slip plate 4 is pressed against the nylon webbing 7. The rotary motor 12 is started, and the output shaft of the rotary motor 12 drives the connecting rod 1 to rotate during the rotation, so as to retract or unwind the insulation blanket body 8. Several nylon webbing 7 are retracted and unwinded simultaneously to protect the insulation blanket body 8.

[0038] Two electric push rods 17 are activated, and the moving ends of the electric push rods 17 move synchronously in the same direction. With the connection of the mounting frame 9, the connecting rod 1 moves along the arc of the top of the greenhouse. The connecting rod 1 evenly rolls up the main body of the insulation blanket 8. At the same time, the movable plate 15 moves in the inner cavity of the telescopic outer plate 14, which enhances the relative movement stability of the telescopic inner plate 16 and the telescopic outer plate 14. During the transmission process, the position adjustment stability of the connecting rod 1 is enhanced.
