Description

Technical Field

[0001] The utility model relates to the technical field of Lentinula edodes cultivation, in particular to a culture medium mixing device for Lentinula edodes cultivation. Background Technique

[0002] Lentinula edodes cultivation is an activity that combines agricultural technology and biological knowledge, aiming to obtain delicious Lentinula edodes through artificial cultivation. The culture media for Lentinula edodes cultivation mainly include wood chips, rice straw, cottonseed hulls, wheat straw, sawdust, distiller's grains, etc. In actual cultivation, these materials are usually mixed in a certain proportion to ensure that the nutrient components and physical properties of the culture medium meet the growth requirements of Lentinula edodes.

[0003] In the patent with the publication number of CN 217989172 U, a culture medium mixing device for Lentinula edodes cultivation is disclosed. When the first motor is started, the stirring assembly rotates at a high speed in the mixing cylinder, facilitating the stirring of the materials in the mixing cylinder. The output end of the second motor is fixedly connected to the mixing cylinder. When the second motor is started, the mixing cylinder rotates, facilitating the turnover of the materials in the mixing cylinder. Moreover, the rotation directions of the first motor and the second motor are opposite, improving the mixing efficiency and quality of the materials.

[0004] Although the above technology can improve the material mixing efficiency through multiple stirrings, the structure of the mixing device is single. The dry culture medium cannot absorb moisture during the stirring process, and the existing harmful microorganisms are not eliminated. Lentinula edodes mycelium needs appropriate humidity to grow normally. Lack of moisture will inhibit the expansion of the mycelium and affect the yield. Microorganisms will also cause pollution of the culture medium, resulting in the need for additional water addition, stirring, and disinfection later. Therefore, it has certain limitations, so innovation is carried out on this technology. Content of the Utility Model

With the cooperation of the extension shaft 6 and the belt, the two first stirring rods 7 can be driven to rotate synchronously, further driving the two first stirring blades 8 to rotate to mix the culture medium in the mixing drum 1. At this time, introduce external water source through the pipeline 3 and spray evenly through a plurality of spray heads 4, so that the culture medium absorbs water during the stirring process. After the first stirring is completed, open the valve on the first feeding pipe 13 to discharge the material into the disinfection box 2. Then drive the disinfection box 2 to operate to release high temperature to kill bacteria and the like in the culture medium in the mixing drum 1. At the same time, under the connection of the connecting shaft 9, the two second stirring rods 10 and the second stirring blades 11 can be driven to rotate to achieve the effect of stirring and high-temperature disinfection.
