Description

Technical Field

[0001] The utility model relates to the technical field of mushroom cultivation, in particular to a mushroom planting machine. Background Art

[0002] Among the many agricultural products grown at home, mushrooms are highly favored because they are rich in nutrition, easy to cultivate and take up little space. The growth of mushrooms requires strict control of environmental conditions, including temperature, humidity, light intensity and carbon dioxide concentration. Although there are some home mushroom cultivation equipment on the market, these equipment are usually equipped with sensors and corresponding adjustment devices for environmental parameters such as temperature, humidity, light and carbon dioxide concentration, but the existing equipment generally has some shortcomings:

[0003] (1) Complex structure: Many devices are complex in design and inconvenient to operate, making them unsuitable for daily use by home users.

[0004] (2) Large size: Some devices are large in size, taking up space in the home, affecting the appearance and convenience of use.

[0005] (3) Lack of automation function: Although many devices are equipped with relevant sensors, they lack a complete automated control system. Users need to frequently adjust various parameters manually, resulting in a poor user experience.

[0006] (4) Unscientific automated control methods: Some existing automated control methods fail to fully consider the impact of factors such as temperature and humidity on carbon dioxide concentration, resulting in inaccurate adjustment of environmental parameters and affecting mushroom growth.

[0007] Among them, the management of carbon dioxide concentration is particularly critical. Appropriate carbon dioxide concentration is conducive to the normal respiration and growth of mushrooms. When the carbon dioxide concentration is too high, the respiration of mushrooms will be inhibited, affecting their growth rate and morphological development, which may lead to problems such as deformed caps and excessively long stipes. Although mushrooms produce carbon dioxide during their growth, an appropriate amount of carbon dioxide is conducive to their growth. When the carbon dioxide concentration is too low, mushrooms will grow slowly and develop poorly, affecting their yield. In addition, temperature also has a significant effect on changes in carbon dioxide concentration. Higher temperatures will accelerate the metabolic activities of mushrooms and increase the production of carbon dioxide; while lower temperatures will slow down metabolism and reduce the production of carbon dioxide.

[0047] like Figure 1 and Figure 2 As shown, the utility model provides a mushroom planting machine, including a machine base and a cover body, the machine base includes a top plate 3, a bottom plate and four side plates, the bottom plate and the four side plates are spliced ​​with mortise and tenon joints, and the top plate 3 is detachably fixed to the upper ends of the four side plates.

The cover body is made of a light-transmitting material. In a specific embodiment, the cover body is made of a light-transmitting acrylic material.

[0048] like Figure 1-Figure 5As shown, the functional room 1 is provided with a first air duct plate 11 and a heat dissipation cavity 12. The top plate 3 is provided with a planting area 100, and the top plate 3 is provided with a first air inlet 31 and a first air outlet 32 ​​on one side of the planting area 100. The first air duct plate 11 is fixedly arranged at the upper end of the heat dissipation cavity 12 and is attached to the top plate 3 to form a first air duct connecting the first air inlet 31 and the first air outlet 32. The first air inlet 31 is provided with a first fan 311 toward the inside of the first air duct.

[0049] refer to Figure 4 and Figure 5 In the embodiment shown, the middle of the top plate 3 is a planting area 100 for holding mushroom strains and nutrients. Three inner partitions are plugged into the lower left corner of the bottom plate to form a heat dissipation cavity 12. The first air duct plate 11 is fixedly connected to the upper end of the heat dissipation cavity 12 by fasteners (not shown in the figure). The upper end surface of the first air duct plate 11 is at the same level as the upper end surfaces of the four side plates of the base. When the top plate 3 is fixed, the first air duct plate 11 fits with the top plate 3 to form a first air duct. For details, refer to Figure 5 Under the action of the first fan 311, the gas in the cultivation chamber 2 and the first air duct circulates internally, so that the gas distribution in the cultivation chamber 2 remains uniform, and local overheating and moisture accumulation are prevented, thereby reducing mold growth.

[0050] like Figure 4 and Figure 5 As shown, the heat dissipation cavity 12 is provided with a third air inlet 121 and a third air outlet 122 connected to the outside, and a semiconductor refrigeration module 45 is fixedly provided in the heat dissipation cavity 12, including a cooling plate 451, the hot end of the cooling plate 451 faces the heat dissipation cavity 12, and the cold end faces the first air duct, and the heat dissipation fan 453 is located at the third air inlet 121, and the air flow enters from the third air inlet 121 and takes the heat out from the third air outlet 122.

[0051] Specifically, refer to Figure 6 The schematic diagram of the structure of the semiconductor refrigeration module 45 shown in the figure, the cold end of the refrigeration plate 451 is provided with a cold end heat sink 452, and the upper end of the cold end heat sink 452 is provided with a plurality of arrayed fins, and the plurality of fins extend to the inside of the first air duct through the mounting port 101, and the hot end of the refrigeration plate 451 is provided with a radiator assembly, and the radiator assembly includes a frame, and wing plates 456 are fixedly provided on both sides of the frame, and the wing plates 456 on both sides are fixedly connected to the inner top plate 3 of the heat dissipation cavity 12 through fasteners, and a hot end heat sink 455 is provided in the frame, and the hot end heat sink 455 is composed of a plurality of parallel heat conducting fins, and the upper end of the frame is fixedly connected with a heat conducting plate 454, the refrigeration plate 451 and the cold end heat sink 452 in sequence from bottom to top. The heat dissipation fan 453 is fixed to the frame, and the air inlet end faces the outside through the third air inlet 121, and the air outlet end faces the hot end heat sink 455.

[0052] Furthermore, combined Figure 4 and Figure 5 The first air duct plate 11 and the top plate 3 of the heat dissipation cavity 12 are connected at a position close to the first air inlet 31, serving as an installation port 101 of the semiconductor refrigeration module 45. The cold end of the semiconductor refrigeration module 45 is arranged inside the first air duct port, and the hot end is arranged inside the heat dissipation cavity 12.

[0053] like Figure 7 As shown, the top plate 3 is provided with a second air duct on the other side of the planting area 100. The side wall of the functional room 1 is provided with a second air outlet 13, the top plate 3 is provided with a second air inlet 33, and a second air duct plate 14 is fixed inside the functional room 1 to form a second air duct connecting the second air inlet 33 and the second air outlet 13. The second air outlet 13 is provided with a second fan 46 facing the outside. Figure 3 As shown, a carbon dioxide sensor 42 is provided on the top plate.

[0054] More specifically, the side panels of the functional chamber 1 are provided with vents connected to the outside, and the middle panel is provided with vents connected to the functional chamber 1 and the cultivation chamber 2. Under the action of the two vents and the second air duct, the second fan 46 sends the gas in the cultivation chamber 2 to the outside. Due to the change in air pressure, the outside air enters the cultivation chamber 2 through the two vents to achieve external circulation. The above structure helps to control the gas concentration in the cultivation environment, especially the concentration of carbon dioxide and oxygen. At the same time, continuous air exchange helps to reduce the risk of mold, bacteria and insect pests, and improve the health and yield of mushrooms.

[0055] like Figure 3 As shown, the width of the first air outlet 32 ​​on the side close to the planting area 100 is smaller than the width on the side away from the planting area 100. A humidifier 47 is arranged in the functional room 1, and the mist outlet 471 of the humidifier 47 extends to the cultivation room 2 and is arranged on the side of the first air outlet 32 ​​close to the planting area 100. A humidity sensor 43 is fixedly provided on the upper end surface of the top plate 3. Due to the difference in width of the air outlet, the air flow velocity at the narrow end is larger than that at the wide end, and the pressure is smaller. The wind direction of the first air outlet 32 ​​is inclined toward the sky above the planting area 100. Through such a structure, the airflow can be more effectively guided to the sky above the planting area 100, promoting air circulation, preventing airflow stagnation in local areas when the second fan 46 is not working, and reducing the problem of uneven temperature and humidity.

[0056] Furthermore, since the humidifier 47 is closer to the planting area 100, after the airflow reaches the sky above the planting area 100, a distribution characteristic is formed in which the upper humidity is lower and the lower humidity is higher. This can prevent the cold air with higher humidity from contacting the inner wall of the cover and condensing into water mist, thereby avoiding water waste, improving the humidification effect, preventing humidity control distortion, and avoiding problems such as blurring of the cover. It can also enable the cold air with higher humidity in the lower layer to better contact the mushrooms, provide moisture, and improve the utilization rate of water resources.

[0057] The humidifier 47 also includes a water tank, an atomizing sheet and other structures. As a mature prior art, the specific structure and position are not shown in the figure. Those skilled in the art can install it at a reasonable position of the functional room 1 as needed.

[0058] Refer to Figure 3 The temperature sensor 41 and the humidity sensor 43 are arranged on a side away from the semiconductor refrigeration module 45 and the mist outlet 471 of the humidifier 47. Under the action of the internal and external circulation of the gas in the cultivation chamber 2, the above arrangement helps to avoid local measurement deviations and ensure that the feedback data obtained by the control system is more representative, thereby making more accurate adjustments and maintaining the stability of the entire cultivation environment.

[0059] like Figure 1 and Figure 2 As shown, a fill light 48 is also provided in the cultivation room 2, and the fill light 48 is provided above the planting area 100. Figure 3 The top cover is shown in the top view structure diagram, and a bracket mounting seat for the fill light 48 is arranged above the planting area 100, and the mounting seat is used to fix the connecting bracket, refer to Figure 1 The fill light 48 is arranged at the top of the bracket. The fill light 48 is specifically a ring-shaped soft light belt, which provides lighting for the mushrooms when the external light is insufficient.

[0060] Further, such as Figure 2 As shown, a light sensor 44 is provided on the outside of the base. Being provided on the outside can better collect the intensity of the external ambient light, and avoid being affected by the fill light 48, which leads to inaccurate collection of external light information. In this embodiment, the light sensor 44 can also be provided with a light shield to further avoid being affected by the fill light 48.

[0061] In particular, a second light sensor 44 is also provided on the bracket for fixing the fill light 48, and the second light sensor 44 is used to detect the light intensity on the surface of the mushrooms.

[0062] The utility model further includes a main control module 4, which is arranged inside the functional room 1. Its specific position is not specifically shown in each structural diagram, and reference is made to Figure 8 The main control module 4 is shown as a schematic connection block diagram, and the main control module 4 is electrically connected to a temperature sensor 41, a carbon dioxide sensor 42, a humidity sensor 43, a light sensor 44, a semiconductor refrigeration module 45, a second fan 46, a humidifier 47 and a fill light 48. The main control module 4 controls the semiconductor refrigeration module 45, the second fan 46, the humidifier 47 and the fill light 48 to regulate the temperature, carbon dioxide concentration, humidity and light intensity inside the cultivation room 2 through the environmental information parameters collected by the above sensors, thereby providing a high-quality mushroom cultivation environment, promoting the growth and development of mushrooms, and thus increasing yield.

[0063] like Fig. 9 In a specific embodiment shown, the main control module 4 includes two ARDU 1 NO control boards, which are named ARDU 1 NO1 and ARDU 1 NO2 for convenience of description:

[0064] ARDU I NO1 is electrically connected to the humidification module DIY-3-01 (i.e., the above-mentioned humidifier 47), the semiconductor refrigeration chip TEC-12703, the humidity sensor DHT-11 and the temperature sensor DS18B20. ARDU I NO1 controls the start and stop of the humidification module DIY-3-01 through the N-type MOSFET transistor Q3. ARDU I NO1 is connected to the semiconductor refrigeration chip TEC-12703 through the relay K1-Re l ay-SPDT, and the cooling fan 453 is connected in parallel with the semiconductor refrigeration chip TEC-12703.

[0065] ARDUI NO2 is electrically connected to the fill light 48, the second fan 46, the light sensor BH1750_2 and the carbon dioxide sensor MH-Z14A. ARDUI NO2 controls the fill light 48 and the second fan 46 through the N-type MOSFET transistor Q1 and the N-type MOSFET transistor Q2 respectively.

[0066] In addition, the first fan 311 is in a normally open state. After the planting machine is started, the first fan 311 is powered on and started. When the semiconductor refrigeration module 45 is not started, the internal circulation of the internal gas of the cultivation room 2 is realized.

[0067] like Figure 1 and Fig. 9 As shown, a touch screen 5 is provided on the outer wall of the function room 1 , and the touch screen 5 is electrically connected to the main control module 4 .

[0068] Furthermore, the main control module 4 is also electrically connected to a wireless communication module, which is used to communicate with an external terminal device. In a specific embodiment, the wireless communication module is an 8266W IFI module, and the user can remotely control the device through a platform such as a mini program to set environmental parameters and switch modes.

[0069] The mushroom planting machine provided by the utility model has an economical and practical structure, a light and compact design, and a beautiful shape, and is suitable for a home environment. The base and the cover of the utility model are both detachable and replaceable, ensuring good support. At the same time, the mortise and tenon joint structure facilitates the replacement and cleaning of components such as sensors and humidifiers 47 inside the functional chamber 1, improving the convenience of maintenance and further adapting to the home environment.

[0070] The following will combine the above structure to explain the working principle of the utility model with an automatic management method:

[0071] The first step is to place the fungus and nutrients in the planting area 100 in the cultivation room 2, and turn on and start the power of the planting machine. After the power is turned on, the first fan 311 is started;

[0072] In the second step, the mode is selected on the touch screen 5 or the terminal device according to the type of mushrooms to be cultivated, and the temperature standard value T is set. A and T B 、Carbon dioxide concentration standard value C A and C B , Humidity standard value H A And the light intensity standard value I A , and switch to automatic management mode, where T A <T B , C A <C B ; The touch screen 5 and the terminal device display the real-time temperature T, the real-time carbon dioxide concentration C, the real-time humidity H and the real-time light intensity I;

[0073] Step 3: When the temperature sensor 41 detects the real-time temperature T>T B When the temperature sensor 41 detects the real-time temperature T≤T A When the main control module 4 controls to close the semiconductor refrigeration module 45;

[0074] When T is detected A ≤T<T B And C>C B When the main control module 4 controls to start the semiconductor refrigeration module 45;

[0075] When the carbon dioxide sensor 42 detects the real-time carbon dioxide concentration C>C A When the carbon dioxide sensor 42 detects the real-time carbon dioxide concentration C≤C A When the main control module 4 controls to turn off the second fan 46;

[0076] When C A ≤C<C B And T>T B When the main control module 4 controls to turn on the second fan 46;

[0077] When the humidity sensor 43 detects the real-time humidity H<H A When the humidity sensor 43 detects the real-time humidity H≥H AWhen the main control module 4 controls to close the humidifier 47;

[0078] When the light sensor 44 detects the external real-time light intensity I≤I A When the main control module 4 controls to turn on the fill light 48; when the light sensor 44 detects the external real-time light intensity I>I A When the main control module 4 controls to turn off the fill light 48;

[0079] Step 4: When the mushrooms are grown, the touch screen 5 or the terminal device is switched to a storage mode or the power is turned off to take out the mushrooms.

[0080] The above parameters can be pre-set according to different mushroom types, or manually input and set. Taking Pleurotus ostreatus as an example, the spore period of Pleurotus ostreatus is T A With T B Set to 12℃ and 20℃ respectively, C A and C B The concentrations were set to 500ppm and 1000ppm respectively, and the mycelium development period was T A With T B Set to 24℃ and 28℃ respectively, C A and C B Set them to 600ppm and 1200ppm respectively. Light intensity and humidity can use more common settings, such as H A Set to 80%, I A Set to 800l x.

[0081] It should be pointed out that the present invention sets two standard values ​​for temperature and carbon dioxide concentration, namely, T A , T B and C A , C B , when T is detected A ≤T<T B And C>C B When the temperature is too high, the respiration of the mushrooms will be promoted, thereby increasing the growth of carbon dioxide. Therefore, when the third fan is turned on, the semiconductor refrigeration module 45 is also turned on to cool down and reduce the growth rate of carbon dioxide concentration. When C A ≤C<C B And T>T B When the carbon dioxide is at a high growth rate, the main control module 4 controls the semiconductor refrigeration module 45 to start and also starts the third fan for ventilation. The above method is used for preventive adjustment to avoid the impact of sudden environmental changes, improve the response speed of the system, reduce the lag reaction time, and especially for the impact between carbon dioxide concentration and temperature changes, so that the environmental parameters can be kept stable more quickly.

[0082] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
