Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of incubators, and in particular to a pepper planting environment simulation experiment device. BACKGROUND

[0002] The growth of peppers is affected by various environmental factors, such as temperature, light, moisture, soil, etc. Through planting environment simulation experiments, these environmental factors can be precisely controlled to find the most suitable combination of conditions for pepper growth, thereby improving the yield and quality of peppers. This not only meets the market demand for high-quality peppers, but also increases the income of growers.

[0003] Planting environment simulation experiments are an integral part of pepper research work, and are generally carried out using a light incubator. The Chinese utility model patent with publication number CN214572040U proposes an LED light incubator with intelligent control of light, which relates to the technical field of light incubators. To solve the problem of low flexibility and poor light control performance of existing LED light incubators during use, the front end of the incubator body is provided with a front door, the rear end of the incubator body is provided with a rear door, the upper part of the incubator body is provided with a water tank, one end of the front door is provided with a linkage controller, one side of the linkage controller is provided with a magnetic ring, the surface of the rear door is provided with a thermometer, the outer wall of the incubator body is provided with a ventilation opening, the middle of the incubator body is provided with a culture rack, the inside of the incubator body is provided with a motor, one side of the motor is provided with a rotating LED light, one end of the water tank is provided with an electromagnetic control valve, one end of the electromagnetic control valve is provided with a pipeline, and one end of the pipeline is provided with a sprayer.

[0004] The above device ensures sufficient light, but still has some shortcomings in actual use.

DETAILED DESCRIPTION

[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below with reference to the drawings. In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are configured only to explain the present application and are not configured to limit the present application. The present application can be implemented without some of the specific details by those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0035] The orientation words appearing in the following description are the directions shown in the drawings and do not limit the specific structure of the present application. In the description of the present application, it should be further noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection or integrally connected; it can be directly connected or indirectly connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] The embodiments of the present application provide a pepper planting environment simulation experiment device, which provides a closed system that can control multiple environmental parameters (such as light, temperature, humidity, etc.) for researchers to simulate the growth of peppers under different growth conditions.

[0037] The experiment device includes a culture box 1, a bracket 5, a switch door, a camera mechanism 6, a lifting mechanism and a touch display screen 9. The culture box 1 is originally modified from a light culture box, and the top of the culture box 1 is provided with an air circulation mechanism 7. The culture box 1 has a cavity, which is divided into a culture chamber and an equipment chamber which are independent of each other by a vertical partition plate 27. The culture chamber is an area for placing pepper plants and has an opening. The left and right side walls of the culture chamber are provided with height adjusting plates 13 on both sides, and the middle parts of the left and right side walls of the culture chamber are provided with flow channels 14, and a plurality of universal nozzles 15 are arranged on the flow channels 14. The bottom of the air circulation mechanism 7 is provided with an air inlet port communicating with the culture chamber, and one end of the two groups of flow channels 14 is connected to an air outlet port of the air circulation mechanism 7. The flow channels 14 and the height adjusting plates 13 on both sides form a lamp groove one, and the groove opening of the lamp groove one is covered with a glass baffle one, and the lamp groove one has at least one culture lamp one 11.

[0038] The outside air is sucked in by the air circulation mechanism 7, and the processed air (filtered to remove dust and microorganisms, heated or cooled to adjust the temperature, humidified or dehumidified to adjust the humidity) is output to the flow channel 14 through the air outlet port of the air circulation mechanism 7, and then sprayed into the culture chamber through the universal nozzle 15. The universal nozzle 15 can adjust the direction to ensure that the air can be uniformly sprayed to every corner of the culture chamber, making the air flow in the culture chamber more uniform, avoiding the situation of poor air flow or dead angle.

[0039] The switch door is hinged to the incubator 1, which can control the opening or closing of the culture chamber opening, facilitating the observation and operation of researchers. The switch door includes an inner door 4 and an outer door 3 arranged outside the inner door 4. The inner door 4 is made of glass, allowing researchers to observe the inside without opening the culture chamber. The side of the outer door 3 facing the inner door 4 is provided with a second lamp slot, and the slot of the second lamp slot is covered with a second glass baffle. The second lamp slot has at least one second culture lamp 12.

[0040] The first culture lamp 11 and the second culture lamp 12 provide full-spectrum light for the plants, simulating the effects of different light conditions on the growth of chili peppers. The first glass baffle and the second glass baffle are used to protect the first culture lamp 11 and the second culture lamp 12 and allow light to pass through. The side of the partition 27 facing the culture chamber is covered with a soft acrylic mirror plate, which can reflect the light of the first culture lamp 11 and the second culture lamp 12, increase the light intensity in the culture chamber, and provide a more suitable growth environment for the plants.

[0041] The two side walls of the incubator 1 and the outer side wall of the outer door 3 are provided with upper and lower air inlets of the first lamp slot or the second lamp slot. The lower air inlet is provided with an air inlet fan 8, and the upper air inlet is provided with an air outlet fan 10. By installing the air inlet fan 8 at the lower air inlet and the air outlet fan 10 at the upper air inlet, an effective air convection can be formed in the first lamp slot or the second lamp slot. The light sources (first culture lamp 11 and second culture lamp 12) in the first lamp slot and the second lamp slot generate heat, which can be carried away by air convection, effectively reducing the temperature in the lamp slot and maintaining the stability and life of the light source.

[0042] The bracket 5 is arranged in the culture chamber, and at least one flowerpot 2 is placed on the bracket 5. The left and right side walls of the culture chamber are provided with height adjustment plates 13, and the height adjustment plates 13 are provided with a plurality of adjustment holes. The two sides of the bracket 5 are provided with hanging ears 16, which can be hooked on the adjustment holes to fix the height of the bracket 5. By selecting different positions of the adjustment holes, researchers can easily adjust the bracket 5 to the desired height, which can adapt to plants of different sizes and growth rates and provide them with the best growth environment. The design of the hanging ears 16 should ensure stability and easy operation, so that the height of the bracket 5 can be quickly and safely adjusted when needed.

[0043] The upper end surface of the bracket 5 is designed as a concave-convex stepped shape, forming several shelves 17, and the height of the shelves 17 decreases from the middle to both sides, while increasing from the end close to the switch door to the end close to the partition 27. Due to the height difference of the shelves 17, plants at different positions can be at different height levels, avoiding the situation of mutual shading of plants due to crowding. In this way, whether located in the center or on both sides, close to the switch door or close to the partition 27, plants can obtain sufficient light, and the growth of plants will be more uniform, reducing the problems of growth retardation or abnormal morphology caused by insufficient light. The stepped design makes it more convenient for researchers to manage and observe plants. The shelves 17 at different heights make it easy for researchers to access and operate each plant, improving work efficiency. The stepped design makes the air flow in the incubator smoother, which is beneficial to reduce the occurrence and spread of diseases and pests, and also provides a more suitable growth environment for plants.

[0044] The shelf part of the shelf 17 is recessed to form a water storage basin 22 for storing water to facilitate automatic water absorption by plants. The outer peripheral surface of the flowerpot 2 is provided with a retaining ring 18 at the upper end, and the flowerpot 2 is placed in the water storage basin 22 with the retaining ring 18 falling on the surface of the shelf 17, ensuring that the flowerpot 2 is stably placed on the water storage basin 22. The inside of the flowerpot 2 is provided with a cotton line 24, one end of which extends into the water storage basin 22, and the other end is located in the flowerpot 2 and is provided with multiple branches radiating around. The cotton line 24 is used as a channel for water transmission, one end of the cotton line 24 is immersed in the water source in the water storage basin 22, and the other end is placed in the soil of the flowerpot 2, and water is transported to the roots of the plants through the capillary action of the cotton line 24. In this way, even without direct watering, plants can obtain the required water through the cotton line. When the water in the soil is absorbed or evaporated by the plants, the cotton line 24 will continue to absorb water from the water source and transport the water to the soil through capillary action, keeping the soil moist.

[0045] The bottom of the water storage basin 22 is provided with a water outlet, and the water outlet is provided with a plug 23. When it is necessary to clean the water storage basin 22 or change the water, the plug 23 can be opened, and the water in the water storage basin 22 can be discharged through the water outlet. The side wall of the water storage basin 22 is provided with an overflow hole 19, and the position height of the overflow hole 19 is the maximum water level height in the water storage basin 22, and the overflow holes 19 of different water storage basins 22 are connected through water pipes 20. When adding water, only the water storage basin 22 with the highest position height needs to be filled with water, and when the water level exceeds a certain height, the excess water will flow out through the overflow hole 19 and flow into the water storage basin 22 at the next height, and the cycle will continue until all the water storage basins 22 are filled with water. One side of the water storage basin 22 is provided with an observation window 21, which is convenient for researchers to observe the water level in the water storage basin at any time and supplement water in time.

[0046] The camera mechanism 6 is arranged in the culture chamber, and its main function is to shoot the image of the plant in the flowerpot 2. Through a high-quality camera and appropriate lighting equipment (culture lamp one 11, culture lamp two 12), a clear plant image can be captured, so as to facilitate the observation of the growth state, health condition and possible plant diseases and insect pests of the plant. The lifting mechanism is located in the equipment chamber, which drives the camera mechanism 6 to realize the lifting movement of the camera mechanism 6 in the culture chamber. This design makes the camera flexible to adjust the shooting angle and height, so as to obtain more comprehensive and detailed plant images. The touch display screen 9 is installed on the outer side wall of the outer door 3, which is electrically connected with the camera mechanism 6 and the lifting mechanism to realize the functions of posture control and image acquisition. Researchers can view the plant images shot by the camera mechanism 6 through the touch display screen, and adjust the shooting angle and height of the camera by operating the lifting mechanism through the control buttons on the interface.

[0047] The side of the partition plate 27 facing the culture chamber is slidingly connected with a mounting seat 26, and the lifting mechanism drives the mounting seat 26 to realize the lifting movement of the camera mechanism 6, so that the camera mechanism 6 can move freely in three-dimensional space to obtain plant images at different heights and angles. The camera mechanism 6 includes a camera and a fixing frame 33 fixed to the mounting seat 26, and the fixing frame 33 is provided with a servo motor one 34. The output end of the servo motor one 34 is downwardly connected with a mounting arm one 29, one end of the mounting arm one 29 is provided with a servo motor two 28. The output end of the servo motor two 28 is downwardly connected with a mounting arm two 32 parallel to the mounting arm one 29, one end of the mounting arm two 32 is provided with a servo motor three 30. The output end of the servo motor three 30 is upwardly connected with a mounting frame 31, and the camera is fixed to the mounting frame 31. Such design can make the whole camera mechanism 6 fold up when passing through the bracket 5, avoiding affecting its lifting.

[0048] The lifting mechanism includes a reduction box 40 arranged at the bottom end face of the equipment chamber, and the input end of the reduction box 40 is connected with a servo motor four. The reduction box 40 receives power from the servo motor four and reduces the rotating speed to increase the torque, so as to ensure that the lifting mechanism has enough power to drive the camera mechanism 6 and move stably. The output end of the reduction box 40 is connected with a lead screw 37, one end of the lead screw 37 is installed to the inner top of the equipment chamber through a bearing seat.

[0049] The side of the partition 27 facing the culture chamber is provided with a groove 36, and the groove 36 is provided with a through groove 35 communicating with the equipment chamber. The groove 36 is covered with a stainless steel band 25 which covers the through groove 35. The stainless steel band 25 crosses the mounting seat 26 (the cooperation between the stainless steel band 25 and the mounting seat 26 is the same as the principle of the steel band on the linear slide module, and will not be described in detail here). The side of the mounting seat 26 away from the fixing frame 33 is provided with a fixing seat 39, the fixing seat 39 extends into the equipment chamber through the through groove 35, the lead screw nut 38 on the lead screw 37 is fixed to the fixing seat 39, and two groups of guide rods 41 passing through the fixing seat 39 are arranged in the equipment chamber, and the two groups of guide rods 41 are arranged on the two sides of the lead screw 37.

[0050] When the servo motor receives the control command and starts to rotate, the speed of the reduction box 40 is reduced and the torque is increased, and then the lead screw 37 is driven to rotate. The lead screw nut 38 cooperates with the lead screw 37 and moves up and down along the axial direction of the lead screw 37. Since the fixing seat 39 is connected with the lead screw nut 38, the mounting seat 26 and the camera mechanism 6 fixed thereon also move up and down.

[0051] According to the above embodiments of the present application, these embodiments do not describe all the details and are not limited to the specific embodiments. Obviously, according to the above description, many modifications and changes can be made. The present description selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present application, so that those skilled in the art can well utilize the present application and make modifications and uses based on the present application. Any modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
