Description

Technical Field

[0001] This utility model relates to the field of greenhouse planting equipment technology, specifically to a greenhouse curtain rolling mechanism. Background Technology

[0002] Greenhouse cultivation technology is widely used in modern agriculture in my country. It regulates the temperature inside the greenhouse by covering it with insulation blankets (or straw curtains), which is crucial for the growth of off-season crops. As the core equipment for automatically rolling up and down the insulation blankets, the performance of the rolling curtain machine directly affects the management efficiency of the greenhouse and the growth environment of the crops.

[0003] In the prior art, patent CN103563687A discloses a greenhouse curtain rolling machine, including a motor, a reducer, a curtain roller, a support arm, and a rocker arm. The motor is connected to the reducer, and the two ends of the output shaft of the reducer are connected to the curtain roller. The curtain roller is provided with a straw curtain end fixing mechanism. The support arm is hinged to the rocker arm, and the other end of the support arm is hinged to a first support fixed relative to the ground. The other end of the rocker arm is hinged to a second support, and the second support is fixed to the housing of the reducer.

[0004] These types of greenhouse curtain rolling machines have the following disadvantages: during the rolling process of the insulation blanket, tearing force is applied to the insulation blanket, which will affect the service life of the insulation blanket with long-term use. At the same time, during the unfolding process of the insulation blanket, it is released by the weight of the insulation blanket. Since the insulation blanket adheres to the upper surface of the greenhouse during the release process, the insulation blanket may be stacked. Therefore, we propose a rolling mechanism for greenhouse curtain rolling machines. Utility Model Content

[0005] The technical problem this utility model aims to solve is to overcome existing defects and provide a winding mechanism for a greenhouse curtain rolling machine. Through the winding assembly, during the winding process, the spring constantly applies elastic force to the support rod two, thereby reducing the tearing force on the insulation blanket during winding and improving its service life. During the release process, the spring continuously applies traction force to the support rod two, so that when the insulation blanket overlaps during release, the support rod two moves rapidly under traction force, thus pulling the overlapping insulation blanket and making it flatter. This effectively solves the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rolling mechanism for a greenhouse curtain rolling machine, including a support base, a support rod rotatably connected inside the support base, an mounting seat fixedly connected to the upper end of the support rod, a greenhouse on the right side of the support base, insulation blankets on both the front and rear sides of the upper surface of the greenhouse, the upper ends of the insulation blankets being fixedly connected to the middle of the upper surface of the greenhouse, and a rolling assembly.

[0007] The winding assembly includes a second support rod, a reducer, a winding shaft, a two-thirds arc-shaped ring, a spring, and a sliding baffle. The second support rod is rotatably connected to the upper end of the first support rod. The reducer is fixedly connected to the right end of the second support rod. The winding shaft is fixedly connected to both ends of the reducer's output shaft. The lower end of the insulation blanket is fixedly connected to the outer surface of the winding shaft. A two-thirds arc-shaped ring is fixedly connected to the outer surface of the second support rod. A sliding baffle is slidably connected to the left side of the outer surface of the two-thirds arc-shaped ring. The right surface of the sliding baffle is adjacent to the left side of the outer surface of the two-thirds arc-shaped ring. A spring is fixedly connected between the two-thirds of the ring. The spring is sleeved on the outer surface of the two-thirds arc ring. Through the winding assembly, the spring constantly applies elastic force to the support rod 2 during the winding process, thereby reducing the tearing force on the insulation blanket during the winding process and helping to improve the service life of the insulation blanket. During the release process of the insulation blanket, the spring always applies traction force to the support rod 2. Therefore, when the insulation blanket overlaps during the release process, the support rod 2 is moved quickly by the traction force, thereby pulling the overlapping insulation blanket and making the insulation blanket flatter.

[0008] Furthermore, a control switch assembly is provided on the outside of the support base. The input end of the control switch assembly is electrically connected to an external power source to control the operation of electrical appliances.

[0009] Furthermore, the winding assembly also includes an internal gear ring, a gear, and a worm gear. The internal gear ring is rotatably connected to the front side of the mounting base. A rotating rod is rotatably connected to the mounting hole on the front surface of the mounting base. A gear is fixedly connected to the rear end of the rotating rod, and the gear meshes with the internal gear ring. A connecting plate is fixedly connected to the rear surface of the internal gear ring. The rear end of the connecting plate is fixedly connected to the front side of the outer surface of the sliding baffle. A worm gear is fixedly connected to the front end of the rotating rod. A worm is rotatably connected to the front surface of the mounting base, and the worm meshes with the worm gear to provide locking and transmit driving force.

[0010] Furthermore, a second motor is fixedly connected to the front surface of the mounting base. The upper end of the output shaft of the second motor is fixedly connected to the lower end of the worm gear. The input end of the second motor is electrically connected to the output end of the control switch group to provide driving force.

[0011] Furthermore, a second pulley is fixedly connected to the rear end of the input shaft of the reducer, and a mounting plate is fixedly connected to the upper side of the outer surface of the second support rod. A first pulley is rotatably connected to the upper side of the mounting plate. The first pulley and the second pulley are connected by a belt drive to transmit driving force.

[0012] Furthermore, a motor is fixedly connected to the upper surface of the mounting plate. The rear end of the output shaft of the motor is fixedly connected to the front end of the pulley. The input end of the motor is electrically connected to the output end of the control switch group to provide driving force.

[0013] Furthermore, a protective cover is fixedly connected to the front surface of the mounting plate to protect the worm gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The winding mechanism of this greenhouse curtain rolling machine has the following advantages:

[0015] 1. Through the winding assembly, the spring constantly applies elastic force to the support rod 2 during the winding process of the insulation blanket, thereby reducing the tearing force on the insulation blanket during the winding process and helping to improve the service life of the greenhouse insulation blanket.

[0016] 2. During the release of the insulation blanket, the spring always applies a traction force to the second support rod. This causes the second support rod to move rapidly under traction when the insulation blanket overlaps during release, thereby pulling the overlapping insulation blanket in the greenhouse and making the insulation blanket in the greenhouse more flat.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-6 This embodiment provides a technical solution: a winding mechanism for a greenhouse curtain rolling machine, including a support base 1, a support rod 2 rotatably connected inside the support base 1, an mounting seat 5 fixedly connected to the upper end of the support rod 2, a greenhouse 3 arranged on the right side of the support base 1, insulation blankets 4 laid on both the front and rear sides of the upper surface of the greenhouse 3, the upper ends of the insulation blankets 4 fixedly connected to the middle of the upper surface of the greenhouse 3, a control switch group 10 arranged outside the support base 1, the input end of the control switch group 10 electrically connected to an external power source, and a winding assembly 7.

[0026] The winding assembly 7 includes a second support rod 71, a reducer 72, a winding shaft 73, a two-thirds arc-shaped ring 74, a spring 75, and a sliding baffle 76. The second support rod 71 is rotatably connected to the upper end of the first support rod 2. The right end of the second support rod 71 is fixedly connected to the reducer 72 (the reducer 72 is a reducer with a self-locking function). The front and rear ends of the output shaft of the reducer 72 are fixedly connected to the winding shaft 73. The lower end of the insulation blanket 4 is fixedly connected to the outer surface of the winding shaft 73. The two-thirds arc-shaped ring 74 is fixedly connected to the outer surface of the second support rod 71. The sliding baffle 76 is slidably connected to the left side of the outer surface of the two-thirds arc-shaped ring 74. A spring 75 is fixedly connected between the right surface of the sliding baffle 76 and the left side of the outer surface of the two-thirds arc-shaped ring 74. The rear surface of the mounting base 5 is a cover plate fixed by bolts. The bolts can be removed to open the cover plate, and then the two-thirds arc ring 74 can be removed from the surface of the support rod 2 71. The sliding baffle 76 can be removed from the rear end of the connecting plate, thereby removing the two-thirds arc plate 74 and the sliding baffle 76, and then replacing the spring 75 to prevent the spring 75 from weakening after prolonged use and failing to work properly. The spring 75 is sleeved on the outer surface of the two-thirds arc ring 74. The winding assembly 7 also includes an internal gear ring 77, a gear 78, and a worm gear 79. The internal gear ring 77 is rotatably connected to the inner front side of the mounting base 5 (the central axis of the circles containing the internal gear ring 77 and the two-thirds arc ring 74 are both connected to the rotational connection point of the support rod 1 2 and the support rod 2 71). The central axes of the two components coincide. A rotating rod is rotatably connected to the mounting hole on the front surface of the mounting base 5. A gear 78 is fixedly connected to the rear end of the rotating rod. The gear 78 meshes with the internal gear ring 77 (both gear 78 and internal gear ring 77 are located inside the mounting base 5, thus protecting the gear 78 and internal gear ring 77 and preventing external dust and debris from adhering to the outer surface of the gear 78 and internal gear ring 77, which would affect the transmission). A connecting plate is fixedly connected to the rear surface of the internal gear ring 77. The rear end of the connecting plate is fixedly connected to the front side of the outer surface of the sliding baffle 76. A worm gear 79 is fixedly connected to the front end of the rotating rod. A worm is rotatably connected to the front surface of the mounting base 5. The worm gear meshes with the worm gear 79. A second motor 9 is fixedly connected to the front surface of the mounting base 5. The output of the second motor 9... The upper end of the output shaft is fixedly connected to the lower end of the worm gear. The input end of motor 29 is electrically connected to the output end of control switch group 10. When motor 29 runs, the output shaft of motor 29 rotates, driving the worm gear to rotate, causing the worm wheel 79 to rotate, which in turn drives the rotating rod to rotate, causing the gear 78 to rotate, which in turn drives the internal gear ring 77 to rotate, causing the connecting plate to rotate around the central axis of the internal gear ring 77. This causes the sliding baffle 76 to slide on the outer surface of the two-thirds arc ring 74. (When the sliding baffle 76 moves, the spring 75 is compressed, which in turn applies elastic force to the support rod 2 71, thereby reducing the tearing force of the winding shaft 73 when winding the insulation blanket 4. During the process of winding the insulation blanket 4 of the greenhouse, the position of the support rod 2 71 changes continuously, thus causing the sliding baffle 76 to move.)This maintains the elastic force exerted by spring 75 on support rod 71, ensuring that spring 75 constantly applies elastic force to support rod 71, thus facilitating the winding of the insulation blanket 4. Motor 9 reverses, causing the arc-shaped baffle 76 to move, thus relaxing spring 75 and pulling support rod 71, resulting in the insulation blanket 4 of the greenhouse overlapping during release.

[0027] A pulley 12 is fixedly connected to the rear end of the input shaft of reducer 72. A mounting plate is fixedly connected to the upper surface of the outer surface of support rod 71. A pulley 11 is rotatably connected to the upper side of the mounting plate. The pulley 11 and pulley 12 are connected by belt drive. A motor 6 is fixedly connected to the upper surface of the mounting plate. The rear end of the output shaft of motor 6 is fixedly connected to the front end of pulley 11. The input end of motor 6 is electrically connected to the output end of control switch group 10. The rotation of the output shaft of motor 6 drives pulley 11 to rotate, which in turn drives pulley 12 to rotate under the transmission of the belt, causing the input shaft of reducer 72 to rotate, and thus the output shaft of reducer 72 to rotate (under the action of reducer 72, the high-speed, low-torque rotation is converted into a high-speed, low-torque rotation). (Switching to a high-torque, low-speed driving force) drives the winding shafts 73 on both the front and rear sides to rotate. During the rotation, the winding shafts 73 wind up the insulation blanket 4 to the outer surface of the winding shafts 73. As the length of the insulation blanket 4 decreases, the position of the winding shafts 73 changes accordingly. A protective cover 8 is fixedly connected to the front surface of the mounting plate (the worm gear 79 and the worm are both located inside the protective cover 8, thus protecting the worm gear 79 and the worm and preventing external impurities from sticking to the surface of the worm gear 79 and the worm and affecting the transmission). The output shaft of the motor 6 reverses, causing the wound insulation blanket 4 to be released from the outer surface of the winding shafts 73. The insulation blanket 4 is subjected to gravity, causing it to adhere to the upper surface of the greenhouse 4 and slide down along the upper surface of the greenhouse 4.

[0028] The working principle of the greenhouse curtain rolling mechanism provided by this utility model is as follows: When rolling up the greenhouse insulation blanket 4, the control switch group 10 is operated to start motor 6 and motor 9. The output shaft of motor 6 rotates, driving pulley 11 to rotate. Under the transmission of the belt, pulley 12 rotates, causing the input shaft of reducer 72 to rotate, and the output shaft of reducer 72 to rotate (under the action of reducer 72, the high speed and low torque rotation is converted into a high torque and low speed driving force). The winding shafts 73 on both sides are driven to rotate. During the rotation, the winding shafts 73 wind up the insulation blanket 4 to the outer surface of the winding shafts 73. As the length of the insulation blanket 4 decreases, the position of the winding shafts 73 changes accordingly. At the same time, the second motor 9 runs, and the output shaft of the second motor 9 rotates, driving the worm gear to rotate, which in turn drives the rotating rod to rotate, causing the gear 78 to rotate, which in turn drives the internal gear ring 77 to rotate. This causes the connecting plate to rotate around the central axis of the internal gear ring 77, which in turn drives the sliding baffle 76 to rotate on the outer surface of the two-thirds arc ring 74. The sliding surface (when the sliding baffle 76 moves, the spring 75 is compressed, which in turn applies a spring force to the second support rod 71, thereby reducing the tearing force of the winding shaft 73 when winding the insulation blanket 4. During the winding process of the winding shaft 73, the position of the second support rod 71 changes continuously, thus causing the sliding baffle 76 to move, thereby maintaining the spring force applied by the spring 75 to the second support rod 71), so that the spring 75 always applies a spring force to the second support rod 71, which facilitates the winding of the insulation blanket 4. To release the insulation blanket 4, reverse motor 6 and motor 9. The output shaft of motor 6 reverses, causing the wound insulation blanket 4 to be released from the outer surface of the winding shaft 73. Under the action of gravity, the insulation blanket 4 adheres to the upper surface of the greenhouse 4 and slides down along the upper surface of the greenhouse 4. Motor 9 reverses, which in turn causes the arc-shaped baffle 76 to move, thereby putting the spring 75 in a relaxed state, which in turn pulls the support rod 71, thus preventing the insulation blanket 4 from stacking during the release process.

[0029] It is worth noting that the motor 6 disclosed in the above embodiments can be YE3-132S-4, the motor 9 can be TYTB-801-4-B34, and the control switch group 10 is provided with control buttons that correspond one-to-one with the motor 6 and the motor 9 and are used to control their switching.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
