Technical Field
[0001] This utility model relates to the field of plant culture technology, and in particular to a tissue culture medium filling machine. Background Technology
[0002] In plant tissue culture, the filling of culture medium is a crucial and fundamental step. With the continuous expansion of the application scope and scale of tissue culture technology, the demand for culture medium filling machines is also increasing. Large-scale tissue culture production, such as some large plant tissue culture bases and factories, can produce millions or even tens of millions of plants annually. This requires filling machines with high-efficiency filling capabilities to meet the demands of rapid, high-volume production and improve overall production efficiency.
[0003] Existing technologies, such as the utility model patent with publication number CN216549579U, disclose a culture medium filling machine, including a mixing tank with a stirring device inside. The mixing tank has a feed inlet with a cover at the top and a discharge outlet on the lower side of one side, with a solenoid valve on the discharge outlet. A dispensing plate with a hollow dispensing chamber is located on one side of the bottom of the mixing tank, and the dispensing chamber and discharge outlet are connected by a connecting pipe. A base is located directly below the dispensing plate, and a support plate is located between the dispensing plate and the base. A slide rail is located on the support plate, and a lifting plate is located between the two slide rails. Cylinders are attached to both ends of the bottom of the dispensing plate, and a filling head is located on the lifting plate. A groove is formed on the upper surface of the base, and a detachable mounting seat is located within the groove. A placement groove is formed on the upper surface of the mounting seat, and a culture bottle is placed in the placement groove. This utility model has the advantages of high filling efficiency, easy disassembly and cleaning of the filling needle, strong applicability, and wide range of applications.
[0004] The above-mentioned technologies have certain drawbacks. First, the mixing tank lacks an effective internal wall cleaning mechanism. During long-term use, the culture medium easily adheres to the inner wall of the tank, making it difficult to clean. This not only affects the mixing effect but may also breed bacteria and contaminate subsequent culture media. Second, the culture bottles are fixed only by the placement slot. During the filling process, if they are subjected to slight shaking or impact from the filling head, the culture bottles are prone to shifting or even tipping over, resulting in inaccurate filling volume of culture medium, spillage, and waste of resources and environmental pollution.
