Description

Technical Field

[0001] This utility model relates to the field of mushroom stick inoculation machine technology, and in particular to a mushroom stick inoculation machine. Background Technology

[0002] With the rapid development of industrialized edible mushroom cultivation, inoculation of mushroom logs is a core production step, and its efficiency and quality directly affect the mycelial survival rate and yield. Traditional manual inoculation relies on operators using handheld inoculation guns to work on each log individually, which suffers from high labor intensity, low efficiency, and high randomness in inoculation location, making it difficult to meet the needs of production capacities of tens of thousands of tons.

[0003] Currently, some companies use separate semi-automatic equipment, such as independent drilling machines and inoculation machines, but this has significant drawbacks:

[0004] Process separation: The mushroom sticks need to be manually handled and transferred multiple times, resulting in a loss of more than 30% in the efficiency of process connection, and the handling process increases the risk of contamination by miscellaneous bacteria;

[0005] Insufficient positioning accuracy: The drilling depth and inoculation position rely on mechanical stop limits, and equipment vibration can easily lead to large deviations. Inconsistent inoculation depth affects the uniformity of mycelium growth.

[0006] Incomplete disinfection coverage: Fixed UV lamps are often used for static irradiation, which creates blind spots in disinfection and is not effective in sterilizing the curved surfaces of the mushroom sticks and the inner walls of the drill holes, resulting in a high contamination rate.

[0007] Design flaws in the feeding device: When the inoculum is conveyed by a lateral spiral feeder or pneumatic pipeline, it is prone to blockage due to moisture and clumping of the inoculum, and the feeding delay causes fluctuations in the inoculation amount.

[0008] Poor stability of the transfer mechanism: When the chain plate or belt drives the mushroom sticks to move, there is a lack of dynamic limit, and mechanical impact causes the mushroom sticks to shift, requiring frequent shutdowns for adjustment;

[0009] Unreasonable spatial layout: The purification unit and the actuator are arranged separately, and the clean airflow cannot effectively cover the drilling / inoculation station, making it difficult to maintain a local Class 100 clean environment. Utility Model Content
