Description

Technical Field

[0002] When breeding wheat, in order to shorten the breeding time, it is necessary to use a light simulator to simulate sunlight and accelerate the growth of wheat. Most of the existing light simulators are directly installed on the top of the wheat seedling box to directly illuminate the wheat seedlings placed in the seedling box. Although this method can illuminate the wheat seedlings, it cannot simulate sunrise, sunset, etc., adjust the light intensity with the change of time period, and adjust the irradiation angle. Moreover, when the light simulator runs for a long time, it generates a lot of heat. If the heat is not dissipated in time, it is easy to cause damage to the light lamp.

[0003] Therefore, the present application provides a wheat breeding lighting simulator to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] refer to Figure 1-6 A wheat breeding light simulator shown includes a mounting box 1, which is a shell with a transparent bottom surface; in order to realize the light simulation experiment on wheat seedlings, a mounting plate 11 is provided in the mounting box 1, and the mounting plate 11 is a rectangular plate, and a light lamp is installed on the mounting plate 11. The light lamp is provided with multiple groups and is connected to an external PLC controller and a power supply. The external PLC controller can control the opening and closing of the light lamp, and can also adjust the current passing through the light lamp;

[0024] In order to enable the device to simulate sunlight more realistically and adjust the lighting angle, a driving mechanism for driving the mounting plate 11 to reciprocate inside the mounting box 1 is also provided in the mounting box 1; the driving mechanism includes a screw 8 and a motor 3, and the internal rotation of the mounting box 1 is connected with a screw 8 and a sliding rod 9 with corresponding positions, and the screw 8 and the sliding rod 9 are respectively connected to the fixed ends of the first telescopic rod 10 and the second telescopic rod 14. The first telescopic rod 10 and the second telescopic rod 14 have the same structure and both include an outer rod and an inner rod. The outer rod is provided with a sliding hole for the inner rod to slide, and a spring 15 is also provided between the inner rod and the outer rod. The telescopic ends of the first telescopic rod 10 and the second telescopic rod 14 are rotatably connected to the mounting plate 11 through the mounting seat 17. The first telescopic rod 10 is provided with a threaded hole 16 meshing with the screw rod 8, and the second telescopic rod 14 is provided with a sliding hole matching the size of the sliding rod 9. One end of the screw rod 8 protrudes from the mounting box 1, and the screw rod 8 is also provided with a driven gear 5. The mounting box 1 is also provided with a motor 3. The output end of the motor 3 is connected with a driving gear 4. The driving gear 4 corresponds to the driven gear 5 in position and the two are meshed. The motor 3 is connected to an external PLC controller.

[0025] In order to adjust the light intensity, an arc plate 7 for adjusting the running trajectory of the mounting plate 11 is also provided on the side wall of the mounting box 1; a detection mechanism for detecting the position of the arc plate 7 is also provided on the inner wall of the mounting box 1; the detection mechanism includes a proximity switch 12, and two groups of proximity switches 12 are provided. The two groups of proximity switches 12 are arranged on the inner wall of the mounting box 1 corresponding to the first telescopic rod 10, and the two groups of proximity switches 12 are used in conjunction with the first telescopic rod 10. When the first telescopic rod 10 is connected to the first group of proximity switches 12, the illumination intensity of the light increases, and when the first telescopic rod 10 is connected to the second group of proximity switches 12, the illumination of the light returns to its original state, simulating the adjustment of the light intensity.

[0026] When the current passing through the lighting lamp is increased, the temperature of the lighting lamp rises. If the heat is not dissipated in time, the lighting lamp may be easily damaged. Therefore, a heat dissipation fin 13 is also provided on the mounting plate 11, and a fan 2 and a dustproof window 6 corresponding to the position of the heat dissipation fin 13 are provided on the mounting box 1, and the fan 2 is connected to the external PLC controller; when the driving mechanism drives the first telescopic rod 10 to contact the first group of proximity switches 12, the fan 2 starts to accelerate the air flow at the heat dissipation fin 13, thereby accelerating the heat dissipation of the lighting lamp to avoid damage due to excessive temperature.

[0027] The working principle of the utility model is as follows: in the simulation care experiment, the device is connected to electricity, and the light lamp is controlled to turn on through the PLC controller to illuminate the wheat seedlings. At this time, the light lamp on the mounting plate 11 is located on the left side of the mounting box 1, simulating the light at sunrise, and the motor 3 is controlled to rotate clockwise, driving the driving gear 4 to rotate, and the driven gear 5 is driven to rotate through the meshing relationship between the driving gear 4 and the driven gear 5, thereby driving the screw rod 8 to rotate. Under the limiting effect of the mounting plate 11, the sliding rod 9 and the second telescopic rod 14, the screw rod 8 cannot drive the first telescopic rod 10 to rotate, and the screw rod 8 is engaged with the screw on the first telescopic rod 10. The first telescopic rod 10 and the second telescopic rod 14 are engaged with each other and move from the left side to the right side in the installation box 1. At this time, the first telescopic rod 10 and the second telescopic rod 14 are in an extended state. As the mounting plate 11 moves to the right, the first telescopic rod 10 and the second telescopic rod 14 are reset under the elastic force of the spring 15. The first telescopic rod 10 and the second telescopic rod 14 contract and drive the top of the mounting plate 11 to slide close to the arc plate 7. The mounting plate 11 is hinged with the first telescopic rod 10 and the second telescopic rod 14 through the mounting seat 17. Therefore, when the mounting plate 11 slides with the arc plate 7, the irradiation angle of the light to the wheat seedlings will be changed, thereby realizing the adjustment of the irradiation angle;

[0028] When the first telescopic rod 10 is connected to the first group of proximity switches 12, the current passing through the illumination lamp is increased through the PLC controller, thereby increasing the illumination intensity of the illumination lamp, simulating the illumination at noon, and the illumination lamp heats up faster. At this time, the fan 2 is controlled to rotate and blow wind toward the heat dissipation fins 13 to speed up the air circulation inside the installation box 1 and improve the heat dissipation of the illumination lamp;

[0029] When the first telescopic rod 10 is connected to the second group of proximity switches 12, the current passing through the illumination lamp is restored to simulate the illumination at sunset; when the mounting plate 11 moves to the right side of the mounting box 1, the illumination of the wheat seedlings for one day is completed, and the motor 3 rotates counterclockwise to drive the components to reset.
