Description

Technical Field

[0001] The invention relates to the technical field of Morchella cultivation, and in particular to a method for preparing Morchella spawn. Background Art

[0002] Morchella strains are the most basic means of production in Morchella production, and play a very important role in determining the yield and quality of Morchella. Morchella strains are divided into primary strains (also called mother strains or test tube strains), secondary strains (also called original strains), and tertiary strains (also called cultivated strains or production strains). Usually, mother strains are used to cultivate original strains, which are then inoculated into the culture matrix to grow into cultivated strains for planting. Strain is the first step in mushroom cultivation. The quality of strains determines the vitality and physiological state of the bacteria, thus affecting the yield of the mushrooms (fruiting bodies) finally harvested.

[0003] The traditional strain production process has significant differences in the growth of each batch of strains due to non-standard raw materials, immature production processes, unclear culture parameters and other reasons. The strain culture cycle is too long, and mycelium aging and reduced vitality occur, which seriously affects the strain quality. Summary of the invention

[0004] The purpose of the present invention is to provide a ratchet wrench which has the effect of shortening the mycelium culture period.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a method for preparing Morchella spp.

[0006] The following steps are involved:

[0007] S1 determines the culture medium formula: wheat grains are 50%-60%, rice husks are 10%-25%, sawdust is 10-20%, soil is 10%-18%, calcium carbonate is 1%, and gypsum is 1%, and the total weight percentage of the above materials is 100%, wherein the wheat grains are mixed with a mixture, and the mixture is an inorganic nitrogen source, carbohydrates and vitamins;

[0008] S2 prepares culture medium: mixes ingredients according to the culture medium formula determined in S1, adds water and stirs, and controls the moisture content of the culture medium to 40%;

[0009] S3: preparing a mushroom bag: using a high temperature resistant polypropylene plastic bag to package the mushroom strain, using a mushroom bag sealing device (1) to cover the mushroom bag, and then heating and sterilizing the mushroom bag and cooling it;

[0010] S4 inoculation: using the middle inoculation method, inserting the Morchella spawn stick in the middle of the fungus bag to increase air permeability and mycelium growth rate;

[0011] S5 Cultivation: The inoculated bacteria bag is placed in a culture room and cultured at 12°C-20°C for 25-40 days until the culture container is full of mycelium for the next level of inoculation or sowing.

[0012] By adopting the above technical scheme, nitrogen sources, carbohydrates and vitamins are added to wheat grains. Carbohydrates provide an energy source for microorganisms, and suitable nitrogen sources and carbon sources promote the growth and reproduction of microorganisms. During the fermentation process, sufficient nutrients accelerate metabolic reactions and increase product formation, thereby shortening the mycelium culture cycle and improving culture efficiency.

[0013] The present invention is further configured as follows: the inorganic nitrogen source is potassium nitrate.

[0014] By adopting the above technical solution, an available nitrogen source is provided for morels to promote their growth and reproduction. Potassium nitrate releases hydrogen ions when dissolved, which has a certain effect on the pH value of the culture medium and helps to maintain a suitable growth environment.

[0015] The present invention is further configured as follows: the wheat grains provide a carbon source, the potassium nitrate provides a nitrogen source, and the ratio of the carbon source to the nitrogen source is 20:1 in terms of mass percentage.

[0016] By adopting the above technical solution, the growth of mycelium is promoted and the activity and yield of the fungus are improved.

[0017] The present invention is further configured as follows: the mushroom bag sealing device (1) comprises a conveying platform for conveying mushroom bags, a conveyor belt driven on the conveying platform and a material discharge chute fixed on one side of the conveying platform, a material transfer platform is arranged on one side of the conveying platform, a material transfer plate is rotatably connected to the material transfer platform, a slot is arranged on the material transfer plate, an end of the material discharge chute is located above the slot, the material transfer platform is equipped with a driving device for driving the material transfer plate to rotate, and also comprises a bag twisting mechanism, a ring mechanism and a capping mechanism which are arranged in sequence along the rotation direction of the material transfer plate, the bag twisting mechanism is used to rotate and close the mouth of the mushroom bag, the ring mechanism is used to connect the ring to the mouth of the mushroom bag, and the capping mechanism is used to connect the cover body to the top of the ring to complete the mushroom bag packaging.

[0018] By adopting the above technical scheme, the mushroom bag filled with culture medium is placed on the conveyor belt for transportation, and the upper opening of the mushroom bag falls into the notch on the transfer plate through the discharge chute. The driving device drives the transfer plate to rotate, and then drives the mushroom bag to rotate around the transfer platform and pass through the bag twisting mechanism, the ring mechanism and the capping mechanism in sequence. The bag twisting mechanism twists and rotates the mouth of the mushroom bag to make the mouth of the mushroom bag in a retracted state, the ring mechanism puts the ring on the mouth of the mushroom bag, and then the capping mechanism drives the cover body to be connected to the ring to complete the automatic packaging of the mushroom bag, thereby realizing the multi-quantity culture of morel mushroom species, improving the culture efficiency, facilitating operation and saving manpower.

[0019] The present invention is further configured as follows: the driving device includes a rotating shaft fixed to the bottom of the material transfer plate and rotating on the material transfer platform, a first gear fixed to the rotating shaft and a driving motor fixed to the bottom of the material transfer platform, the output end of the driving motor is fixed with a second gear meshed with the first gear, both ends of the conveying platform are rotatably connected with transmission rollers, the conveyor belt is sleeved between the two transmission rollers, both ends of the transmission roller are fixed with roller shafts, the bottom end of the rotating shaft is fixed with a first bevel gear, the bottom end of the material transfer platform is rotatably connected with a transmission shaft, the transmission shaft is fixed with a second bevel gear meshed with the first bevel gear, and the transmission shaft and the roller shaft are connected by a transmission belt.

[0020] By adopting the above technical solution, the driving motor drives the second gear to rotate and then drives the first gear and the rotating shaft to rotate, driving the material transfer plate to rotate around the material transfer platform to transport the mushroom bag. During this period, when the material transfer plate and the rotating shaft rotate, the first bevel gear, the second bevel gear and the transmission shaft rotate synchronously, and the roller shaft and the transmission roller are driven to rotate by the transmission belt, so that when a mushroom bag enters the next step of the process, the conveyor belt transports the next mushroom bag so that it passes through the discharge chute and falls into the slot, thereby realizing continuous sealing of multiple mushroom bags and improving packaging efficiency.

[0021] The present invention is further configured as follows: the notches are evenly distributed along the circumference of the material transfer plate, and a discharge port corresponding to one of the notches is provided at the bottom of the material transfer platform.

[0022] By adopting the above technical solution, when the material transfer plate drives the mushroom bag through the bag twisting mechanism, the ring mechanism and the capping mechanism, after the mushroom bag is sealed, the material transfer plate drives the mushroom bag to continue to rotate around the material transfer table until the discharge port corresponds to the groove, and the mushroom bag falls out of the discharge port to realize automatic unloading.

[0023] The present invention is further configured as follows: the bag-twisting mechanism includes a bag-twisting frame, a bag-twisting shaft rotating on the bag-twisting frame, a third gear and a clamping assembly respectively fixed to the upper and lower ends of the bag-twisting shaft, a bag-twisting motor installed on the bag-twisting frame, and a fourth gear fixed to the output end of the bag-twisting motor and meshing with the third gear; the material transfer platform is fixed with a fixing frame, the material transfer plate is provided with a plug hole leading to the slot, a limiting rod is inserted and slidably on the fixing frame, the rear end of the limiting rod passes through the plug hole and extends into the slot, the end of the limiting rod is configured as an arc shape, and a limiting spring is fixed between one end of the limiting rod away from the slot and the fixing frame.

[0024] By adopting the above technical scheme, the mushroom bag falls into the notch on the material transfer plate through the material discharge chute. When the material transfer plate drives the mushroom bag to move close to the bag twisting mechanism, the limit rod extends into the notch after the limit spring pushes the lower end through the insertion hole and abuts against the bag body of the mushroom bag to clamp the bag body of the mushroom bag and restrict its movement. The clamping assembly clamps the bag mouth of the mushroom bag, and the bag twisting motor drives the third gear and the bag twisting shaft to rotate through the fourth gear, thereby driving the clamping assembly and the clamped bag mouth of the mushroom bag to rotate, so as to achieve the closing of the bag mouth of the mushroom bag, which is convenient for subsequent ring and capping work; then the clamping assembly releases the bag mouth of the mushroom bag, and the material transfer plate continues to rotate to drive the mushroom bag forward. The inner wall of the insertion hole pushes the end of the limit rod to extend out of the notch, and the limit spring contracts, so that during the rotation of the material transfer plate, the end of the limit rod abuts against the outer wall of the material transfer plate.

[0025] The present invention is further configured as follows: the ring mechanism includes a ring frame, a material guide trough fixed on the ring frame and a ring cylinder, a second group of the clamping components is fixed to the output end of the ring cylinder, the capping mechanism includes a capping frame, a second material guide trough fixed to the capping frame, a material storage rack close to the capping frame, a material storage table sliding on the material storage rack, a lifting cylinder close to the material storage rack, a capping cylinder fixed to the output end of the lifting cylinder and a third group of the clamping components fixed to the output end of the capping cylinder, a sliding rod inserted and slidable on the material storage rack is fixed to the bottom of the storage table, a telescopic spring sleeved on the outside of the sliding rod is fixed between the storage table and the storage rack, and a material discharge port and a control component for controlling the switch of the material discharge port are provided at the bottom of the material guide trough.

[0026] By adopting the above technical scheme, the rings are placed side by side on the material guide trough, and the cover body is placed side by side on another material guide trough. The control component controls the feed opening switch, and the feed opening of the material guide trough with the ring is located directly above the trough opening; when the material transfer plate drives the mushroom bag to move close to the ring mechanism, the clamping component first clamps the mushroom bag opening to a limit position, and the control component controls the feed opening to open, and the ring falls from the material guide trough to be sleeved on the bag opening of the mushroom bag, and the clamping component limits the position of the ring. Then the control component controls the feed opening of another material guide trough to open, and the cover body falls from the material guide trough to the material placement table, and the clamping component clamps the cover body on the material placement table. The output end of the covering cylinder extends to drive the clamping component and the cover body to move above the mushroom bag. When the cover body moves to above the ring on the mushroom bag, the output end of the lifting cylinder returns to drive the cover body to be pressed down, and finally the cover body is covered above the ring to achieve the sealing work of the mushroom bag.

[0027] The present invention is further configured as follows: the control component includes two baffles that slide in mirror image at the discharge port, a control motor fixedly mounted on the material guide trough and a control gear fixed to the output end of the control motor, racks located on both sides of the control gear are fixed on the same side of the two baffles, a T-shaped bar is fixed at the bottom of the material guide trough, and the baffle is provided with a T-shaped slot that slides on the T-shaped bar.

When the baffle moves, the T-bar slides in the T-slot to achieve limiting guidance, making the control process more stable.

[0029] The present invention is further configured as follows: the clamping assembly includes a frame, a screw rod rotatably connected to the frame, a guide rod fixed to the frame and parallel to the screw rod, and a clamping motor driving the screw rod to rotate, both ends of the screw rod are provided with bidirectional threads, and both ends of the screw rod are threadedly connected to a clamping plate that slides on the guide rod.

[0030] By adopting the above technical solution, during the clamping operation, the clamping motor drives the screw rod to rotate, the guide rod is restricted, and the clamping plates at both ends are driven to move relative to each other to clamp the mushroom bag.

[0031] The beneficial effects of the present invention are:

[0032] 1. Add nitrogen source, carbohydrates and vitamins to wheat grains. Carbohydrates provide energy sources for microorganisms. Appropriate nitrogen source and carbon source promote the growth and reproduction of microorganisms. During the fermentation process, sufficient nutrients accelerate metabolic reactions and increase product generation, thereby shortening the mycelium culture cycle and improving the culture efficiency.

[0056] Working principle: The bacteria bag filled with culture medium is placed on the conveyor belt 3 for transportation. The upper opening of the bacteria bag falls into the slot 16 on the transfer plate 6 through the feed chute 4. The driving motor 73 drives the second gear 74 to rotate and then drives the first gear 72 and the rotating shaft 71 to rotate, driving the transfer plate 6 to rotate around the transfer platform 5 to transport the bacteria bag.
