Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical equipment, in particular to a handheld tremella rod opening device. BACKGROUND

[0002] In the fruiting management stage of tremella cultivation, the rod needs to be opened before the bud is induced, the purpose is to provide a directional fruiting channel for tremella mycelium, promote the formation of primordium, and at the same time, enhance the ventilation and air permeability inside and outside the rod, adjust the temperature and humidity environment, and guarantee the quality and yield of tremella fruiting. At present, the opening of the tremella rod mainly depends on manual operation, and the specific method is that the operator holds a self-made half stainless steel double-edged blade, and cuts a pre-designed shape and size notch on the side of the rod bag.

[0003] The current manual opening method has many technical defects: first, the labor intensity is large, the operator repeats the holding and cutting action for a long time, holds the rod with one hand, and holds the self-made blade with the other hand to complete the left and right circular arc scraping film and the first film picking action, which is repeated thousands of times a day, which is easy to cause hand fatigue, and the operation safety in the mushroom house is difficult to guarantee; second, the opening quality is poor, the manual operation depends on experience, the consistency of the notch depth, size and shape is poor, and problems such as notch too deep to damage mycelium and notch too shallow to form effective fruiting channel may occur, which directly affects the tremella fruiting rate and quality; At present, although there are a small number of opening equipment related researches for edible fungus rods, most of them are large fixed devices suitable for factory flow line operation, which cannot adapt to the operation scene in the narrow channel of the existing mushroom house; and the existing devices are not specially designed for the material characteristics (such as rod hardness and bag film thickness) and opening process requirements (such as precise depth control and mycelium scratch prevention) of tremella rod, which is difficult to meet the personalized needs of tremella cultivation; The existing patent application numbers CN202410696777.X handheld tremella rod hole expander, CN202410696840.X small semi-automatic tremella rod hole expander, and CN202421235510.2 portable tremella rod hole expander all cut the rod film by rotating the blade driven by the motor for one revolution, and the waste film and rod surface layer are collected by the inverted needle rod. The motor drive method contains a motor and a battery, which increases the weight of manual operation, and the device is large and heavy. The depth of the blade cannot be adjusted, and the inverted needle rod will damage the mycelium and affect the tremella fruiting rate and quality. The hole expansion method of the above three invention patents is changed from the original worker holding the rod with one hand and expanding the hole with the other hand to positioning the rod and then automatically or single-handedly or double-handedly expanding the hole. Therefore, developing a handheld tremella rod opening device with compact structure, portable operation, precise opening, and adaptation to mushroom house operation has become the key to solving the current technical problems.
