Description

Technical Field

[0001] This utility model relates to the field of fungal culture technology, and in particular to a propagation rack. Background Technology

[0002] Fungi, as an important agricultural product, are widely used in food, medicine, and other fields, and their propagation efficiency and quality directly affect the development of the industry. Traditional fungi propagation racks are mostly simple multi-layered support structures, where fungi are cultivated by placing mushroom sticks or bags in layers. These racks are primarily designed with fixed layer spacing, meeting basic multi-layer cultivation needs and achieving a certain degree of space utilization. With the development of fungi cultivation technology, the demand for intelligent systems has gradually emerged, and some propagation racks have begun to incorporate basic functions such as temperature and humidity monitoring to assist in the artificial control of the cultivation environment. However, facing the diverse fungi varieties and the specific needs of different growth stages, existing propagation racks still have room for improvement in terms of functional expandability, precision of environmental control, and flexible space utilization, urgently requiring further optimization and innovation to meet the higher requirements of modern fungi propagation.

[0003] For example, Chinese utility model patent (CN219961539U) discloses a spawn cultivation rack that solves the following problem: existing support racks have multiple layers, and the upper support rack is too high to conveniently place bagged spawn. This device includes a fixed support plate; a U-shaped frame is slidably connected to the fixed support plate via a sliding assembly; a Y-axis displacement assembly is provided on the fixed support plate; support bars are fixedly connected to the fixed support plate; a placement plate is provided on the support bars; a groove is provided on the placement plate; the support bars pass through the grooves; a second support bar opposite to the support bars is fixedly connected to the U-shaped frame; a fixed plate is slidably connected to the U-shaped frame via a second sliding assembly; an X-axis displacement assembly is provided on the U-shaped frame; a fixed assembly is provided on the fixed plate, which fixes the placement plate, then moves it via the Y-axis displacement assembly, and finally moves it to the support plate via the X-axis displacement assembly for convenient placement of bagged spawn at a higher position.

[0004] When using the above technology, the following technical problems were found in the existing technology: the device does not have a heat dissipation structure, which may cause the temperature inside the culture rack to be too high, thereby inhibiting the growth of the strain or even causing it to die; and the device does not have a convenient installation structure, which will require users to spend more time and effort to install, affecting the stability and service life of the culture rack. To address these issues, we have designed a breeding rack to provide another technical solution. Utility Model Content

[0050] Multiple circular through holes are provided on the inner side of the support plate 33, which allows the device to ventilate and cool down.

[0051] The present invention provides a breeding rack. The device, through the design of a cooling structure, can effectively control the temperature inside the breeding rack, ensuring that the strains grow under constant temperature conditions. This is crucial for most strains, as excessively high or low temperatures can affect the growth rate and health of the strains. Therefore, the temperature inside the breeding rack can be precisely adjusted to create a suitable environment for the growth of the strains.

[0052] The device's installation and support structure design significantly reduces installation time and costs. This structure allows the various components of the culture rack to be assembled quickly and easily without the need for complex tools or professional skills. This not only reduces installation difficulty but also improves installation efficiency, enabling the culture rack to be put into use more quickly.

[0053] The usage process of the breeding rack provided by this utility model is as follows: The user threaded the lead screw 15 to the top of the mounting column 2, and slides the support plate 33 to the outside of the two support rods 34. The user pulls the handle 29, which causes the limiting strip 26 to disengage and engage with the limiting wheel 25. Then, the user rotates the handle 22, which drives the worm gear 23 to rotate. Since the worm gear 23 is engaged with the worm wheel 24 on one side, it drives the rotating rod 19 to rotate. The rotation of the rotating rod 19 drives the clamping plate 20 to rotate, so that the clamping plate 20 and the clamping block 17 can clamp the support rod 34. Then, the user releases the handle 29. Under the elastic force of the spring 28, the user pushes the pull rod 27 and the limiting strip 26 to re-engage with the limiting wheel 25. The user places the fungi on the top of the support plate 33, and then powers on the third motor 13. The output of the third motor 13 drives the cooling fan 14. The first motor 6 rotates, and its output drives the first screw 7 to rotate. Since the outer thread of the first screw 7 is connected to the mounting block 8, the rotation of the first screw 7 causes the mounting block 8 to move along both sides of the top of the slide rail 3. The user then powers on the second motor 11, which in turn powers the second screw 12. The output of the second screw 12 then powers the mounting block 8, allowing the mounting block 8 to move at both ends of the top of the slide rail 3. This allows the cooling fan 14 to cool the fungi comprehensively. When the temperature is too low, the user powers on the heating wire 36, which in turn allows the cooling fan 14 to blow hot air to heat the device. At this time, the device's thermometer 35 can accurately measure the temperature of the device, ensuring that the fungi grow under suitable temperature and humidity conditions, improving the yield and quality of the fungi, reducing energy consumption, and ensuring the safety of equipment and personnel, thus greatly improving the efficiency of the device.
