TECHNICAL FIELD

[0001] The present application relates to the technical field of selenium-rich agricultural products, and particularly relates to a selenium-rich edible fungus culture device. BACKGROUND

[0002] Selenium-rich edible fungus will have excellent effects of selenium and itself, and become a high-efficiency agricultural product for keeping human health. A large number of studies have shown that the medicinal active substance level of selenium-rich edible fungus is increased after selenium-rich cultivation. Selenium-rich edible fungus is a food frequently eaten by people, and the growth of selenium-rich edible fungus must have suitable temperature conditions and must provide and maintain a clean growth environment. However, in the prior art, the laboratory cultivation of selenium-rich edible fungus usually adopts a fungus rod for inoculating mycelium for cultivation, and in the cultivation process, an experimenter needs to open a selenium-rich edible fungus incubator for multiple times to detect the temperature and humidity of the fungus rod, and needs to manually spray selenium-rich nutrient solution on the fungus rod to ensure the humidity of the fungus rod. Since the experimenter opens the incubator for multiple times, the bacteria in the laboratory are brought into the incubator, which affects the growth of selenium-rich edible fungus. If the selenium-rich nutrient solution is sprayed too much, the humidity of the culture soil is too large, which causes the selenium-rich edible fungus to rot. After the selenium-rich edible fungus grows into a mushroom, the selenium-rich nutrient solution is sprayed, and the selenium-rich nutrient solution is sprayed on the umbrella cover of the selenium-rich edible fungus, which causes the selenium-rich nutrient solution to rot the selenium-rich edible fungus, affects the number of experimental samples, causes the lack of samples, and causes experimental loss. Moreover, the manual spraying of the selenium-rich nutrient solution cannot uniformly distribute the selenium-rich nutrient solution on the fungus rod, which affects the absorption of selenium by the selenium-rich edible fungus in the growth process of the selenium-rich edible fungus, and causes the selenium content of the selenium-rich edible fungus to decrease. SUMMARY

[0003] In order to overcome the shortcomings that the experimenter opens the incubator for multiple times to detect the temperature and humidity, brings bacteria into the incubator, affects the growth of selenium-rich edible fungus, and directly sprays the selenium-rich nutrient solution, which causes the selenium-rich nutrient solution on the surface of the selenium-rich edible fungus to rot the selenium-rich edible fungus after the selenium-rich edible fungus grows, the selenium-rich nutrient solution cannot be uniformly distributed on the fungus rod by the manual spraying of the selenium-rich nutrient solution, which affects the absorption of selenium by the selenium-rich edible fungus in the growth process of the selenium-rich edible fungus, and causes the selenium content of the selenium-rich edible fungus to decrease, the present application provides a selenium-rich edible fungus culture device.

[0044] The twister 203 is arc-shaped; the arc-shaped twister 203 is better adapted to the part of the culture bottle 5 that is concave arc-shaped, the culture bottle 5 is more easily twisted at the concave arc-shaped part, the culture bottle 5 is twisted at a larger angle at the concave arc-shaped part, the selenium-rich edible fungus is better protected, and the selenium-rich edible fungus is prevented from being damaged when the injection needle 6 is inserted into the culture bottle 5.

[0045] The driving member 202 is further included; the driving member 202 is fixed on each fixed block 201, the driving end of each driving member 202 is fixed with the adjacent twister 203, and the driving member 202 is an electric push rod; the driving member 202 applies a pushing force to the side of the culture bottle 5 that is concave arc-shaped, the side of the culture bottle 5 that is concave arc-shaped is twisted and recessed into the bottle, the cap of the selenium-rich edible fungus that covers the insertion hole 5001 is inclined to the recessed side of the culture bottle 5, and the covered insertion hole 5001 is leaked.

[0046] After the selenium-rich edible fungus grows out, the cap of the selenium-rich edible fungus covers the insertion hole 5001 when the cap of the selenium-rich edible fungus grows out of the bottle mouth of the culture bottle 5; at this time, the driving member 202 is controlled to drive the twister 203 to move to the culture bottle 5; when the twister 203 completely adapts to the side of the culture bottle 5 that is concave arc-shaped, continued movement to the culture bottle 5 applies a backward extrusion force to the culture bottle 5, the concave arc-shaped part of the culture bottle 5 is recessed into the bottle of the culture bottle 5, and the concave arc-shaped part of the culture bottle 5 is twisted backward; at this time, the concave arc-shaped part of the culture bottle 5 drives the selenium-rich edible fungus at the bottle mouth to first incline to the right and then incline to the back side, the insertion hole 5001 covered by the cap of the selenium-rich edible fungus is leaked, and the injection needle 6 is inserted into the culture soil through the insertion hole 5001 to inject the selenium-rich nutrient solution; the above working process solves the problems that the selenium-rich edible fungus grows out of the bottle mouth of the culture bottle 5 after the selenium-rich edible fungus grows out, the insertion hole 5001 on the culture bottle 5 is covered by the cap of the selenium-rich edible fungus, the culture soil cannot be injected with the nutrient solution, the selenium-rich edible fungus is not grown in sufficient humidity, and the cap of the selenium-rich edible fungus is damaged when the injection needle 6 is inserted into the insertion hole 5001 on the culture bottle 5, and ensures the growth integrity of the selenium-rich edible fungus.

[0047] Example 3

[0048] On the basis of example 2, as Figure 9As shown, it also includes an airbag 301; several airbags 301 are fixed on the base plate 4, and each airbag 301 is located on the lower outer side of the adjacent culture bottle 5; the airbag 301 is inflated by an external air pump, causing the airbag 301 to expand and generate a squeezing force on the culture bottle 5, so that the culture soil at the bottom of the culture bottle 5 is squeezed to the top of the culture bottle 5 by the squeezing force, filling the gaps in the culture soil after the culture bottle 5 is twisted and dented, stabilizing the growth of selenium-enriched edible fungi, and ensuring the survival rate of selenium-enriched edible fungi.

[0049] When the torsion device 203 causes the concave arc-shaped part of the culture bottle 5 to indent and twist backward, the concave arc-shaped part of the culture bottle 5 causes the selenium-enriched edible fungi growing at the bottle mouth to tilt to the right and rear. Due to the concave and twisting of the concave arc-shaped part of the culture bottle 5, gaps are created in the culture soil inside the culture bottle 5. At this time, the external air pump is controlled to inflate the air bag 301, causing the air bag 301 to expand and squeeze the plastic culture bottle 5, squeezing the culture soil at the bottom of the culture bottle 5 upward, causing the culture soil at the bottom of the culture bottle 5 to move upward, and thus filling the gaps in the culture soil at the top of the culture bottle 5. The above process solves the problem of the gaps created by the concave and twisting of the concave arc-shaped part of the culture bottle 5, which makes the roots of the selenium-enriched edible fungi unstable and unable to absorb the selenium-enriched nutrient solution normally, thus ensuring the survival rate of the selenium-enriched edible fungi.
