Description

Technical Field

[0001] The present invention relates to the technical field of edible fungus cultivation, and in particular to a single-row, multi-position, self-adaptive, constant-pressure inoculation device. Background Art

[0002] When inoculating large batches of logs with fungus, to reduce the number of times the fungus needs to be added to the inoculation equipment and improve inoculation efficiency, the inoculation equipment is usually equipped with a silo that can hold a large amount of fungus. This silo is then continuously fed by gravity to an inoculation tube, which then inoculates the logs with the fungus. However, the silo is prone to clogging during the process of feeding the fungus to the inoculation tube, preventing the tube from completely filling. This results in inconsistent amounts of fungus each time the tube is inoculated with the log, adversely affecting the yield and quality of the edible fungi. Summary of the Invention

[0003] The single-row, multi-position, adaptive constant-pressure inoculation device of the present invention improves the problem of lack of consistency in the amount of inoculated bacteria in the prior art, and can improve the consistency of the amount of inoculated bacteria.

[0004] To achieve the above objectives, the present invention provides a single-row, multi-position, adaptive constant-pressure inoculation device, comprising:

[0005] A feeding system, the feeding system comprising a first silo and a stirring assembly, the stirring assembly being rotatably disposed in the first silo;

[0006] An inoculation system, comprising an inoculation tube connected to the first silo and arranged along a secant line of the rotation trajectory of the stirring assembly, wherein the communication port between the inoculation tube and the first silo corresponds to the stirring assembly;

[0007] Wherein, the stirring component is at least used to transport the bacterial strain into the inoculation tube. When the single-row, multi-position adaptive constant pressure inoculation device of the present invention is used, the bacterial strain to be inoculated is stored in the first silo, and the logs to be inoculated are installed corresponding to the inoculation tube. Before inoculation, the stirring component rotates so that the bacterial strain in the first silo follows the movement to avoid clogging of the bacterial strain, and at the same time, the bacterial strain is transported into the inoculation tube, so that the bacterial strain in the inoculation tube is full or nearly full each time it is inoculated, thereby improving the consistency of the amount of inoculated bacterial strain during multiple inoculations, and further having a favorable effect on the yield and quality of edible fungi.

[0008] As an optional technical solution, the stirring assembly includes a first blade and a second blade, the first blade and the second blade are coaxially arranged, and the angle between the extension direction of the first blade and the extension direction of the second blade is greater than 0° and less than or equal to 90°, the first blade is arranged at the feed port of the first silo, and the second blade is arranged at the connecting port between the first silo and the inoculation tube. When the fungus enters the first silo, it needs to pass through the rotation trajectory of the first blade. At this time, the first blade can break up the clumps of fungus entering the first silo, thereby improving the uniformity of the fungus; the fungus broken up by the first blade is then loaded into the inoculation tube by the second blade, so that the internal structure of the fungus inoculated into the log by the inoculation tube is uniform, which is conducive to reducing the differences in the quality of edible fungi grown from the fungus.

[0009] As an optional technical solution, the second paddle includes a supporting surface, the normal of which is perpendicular to the diameter of the second paddle's rotational trajectory, and the edge of the supporting surface facing away from the first paddle mates with the wall of the first silo where the communication port is located. When the second paddle rotates, the edge of the supporting surface mates with the wall of the first silo, thereby moving the bacterial strains located on the side of the communication port within the first silo and ultimately allowing them to enter the inoculation tube, thereby reducing dead angles within the first silo and preventing the bacterial strains from being retained in the first silo for a long time and deteriorating.

[0010] As an optional technical solution, the inoculation system further includes a sleeve, a piston, and a valve plate. The sleeve is connected to the first silo and is arranged corresponding to the stirring assembly. The inoculation tube is slidably arranged inside the sleeve and is connected to the first silo through the connecting port between the sleeve and the first silo. The piston is slidably arranged on the inoculation tube. The valve plate is arranged at the end of the inoculation tube, and the valve plate is used to close when the pressure on the valve plate is less than a threshold value and to open when the pressure on the valve plate is greater than or equal to the threshold value. Before inoculation, the stirring assembly rotates to fill the inoculation tube with bacterial strains. At this time, the pressure on the valve plate is less than the threshold value, and the valve plate remains closed, which helps to prevent the bacterial strains from spilling from the inoculation tube. During inoculation, the inoculation tube and the piston slide axially along the sleeve until the edge of the inoculation tube contacts the edge of the inoculation hole on the log, and the inoculation tube stops moving. At this time, the piston continues to move, cooperating with the closed valve plate to compact the bacteria in the inoculation tube until the pressure on the valve plate reaches the threshold value. The piston continues to move so that the compacted bacteria enters the inoculation hole of the log to complete the inoculation. The magnitude of the pressure on the bacteria is the threshold value. Since the inoculation tube continues to move toward the log before contacting the surface of the log, the single-row, multi-position adaptive constant pressure inoculation device of the present technical solution can adapt to logs of different diameters and complete the inoculation. At the same time, the valve plate makes the bacteria in the inoculation tube be subjected to a pressure of the threshold value and then inoculated into the log, achieving the purpose of constant pressure, which is conducive to making the internal structure of the bacteria inoculated into the log by the inoculation tube uniform and reducing the difference in the quality of edible fungi grown from the bacteria.

[0011] As an optional technical solution, the inoculation system further includes a first driver and a position sensor. The first driver is connected to the piston, and the position sensor is provided corresponding to the piston. The position sensor signal is connected to the first driver. The position sensor can identify the position of the piston and, therefore, whether the inoculation process is complete. After inoculation is complete, the first driver can stop driving the piston to prevent the piston from affecting the inoculated strain.

[0012] As an optional technical solution, the feeding system also includes a second silo, which is connected to the feed port of the first silo, and the volume of the second silo is larger than that of the first silo, and the second silo is used to provide bacterial strains to the first silo. Since the stirring component is provided in the first silo, in order to avoid excessive resistance when the stirring component rotates, the first silo needs to limit its volume, thereby limiting the amount of bacterial strains contained therein. By providing a second silo with a volume larger than that of the first silo, a large amount of bacterial strains can be stored in the second silo, and the second silo continuously supplies bacterial strains to the first silo, the frequency of adding bacterial strains to the single-row, multi-position adaptive constant pressure inoculation device of this technical solution can be reduced, which is conducive to improving the inoculation efficiency.

[0013] As an optional technical solution, it also includes a clamping system, which is arranged corresponding to the inoculation tube and is used to clamp and / or rotate the wood segment.

[0014] As an optional technical solution, the clamping system includes: a second driving member, a clamp and a motion control component, the second driving member is connected to the motion control component, the clamp is connected to the motion control component or the second driving member, and the motion control component is used to control the motion state of the clamp. The clamp is driven by the second driving member to rotate, thereby rotating the log, so that the inoculation holes on different sides of the log are aligned with the inoculation tube, and the motion control component can stop the clamp from rotating when it rotates to the appropriate angle. The single-row, multi-position adaptive constant pressure inoculation device of this technical solution can reduce manual intervention in the process of strain inoculation, which is conducive to saving labor and improving inoculation efficiency.

[0015] As an optional technical solution, the system further includes a mounting frame comprising a horizontal beam and two longitudinal beams, the two longitudinal beams being arranged in parallel, the ends of the horizontal beam being connected to the ends of the two longitudinal beams on the same side, the feeding system and the inoculation system being mounted on the horizontal beams, and the clamping system being mounted on the longitudinal beams. The mounting frame of this technical solution forms a door-like structure, facilitating the installation of a conveyor belt or other conveying device under the horizontal beams to transport the logs, thereby improving the efficiency of inoculating large quantities of logs with fungus.

[0016] As an optional technical solution, there are multiple inoculation systems, which are arranged along the extension direction of the beam. The multiple inoculation systems of this embodiment can simultaneously inoculate multiple inoculation holes in the same row on the same log, which is conducive to improving inoculation efficiency.

[0017] The one or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0018] The single-row, multi-position, adaptive constant-pressure inoculation device of the present invention arranges a stirring component in the first silo of the feeding system, so that the stirring component rotates to drive the bacterial strain in the first silo to move, thereby avoiding blockage of the bacterial strain, and transporting the bacterial strain to the inoculation tube connected to the first silo, so that the bacterial strain in the inoculation tube is full or nearly full during each inoculation, thereby improving the consistency of the inoculated bacterial strain amount during multiple inoculations, and further having a favorable effect on the yield and quality of edible fungi.

[0033] Example 1

[0034] This embodiment provides a single-row, multi-position, adaptive, constant-pressure inoculation device, comprising a feeding system 1 and an inoculation system 2. Feeding system 1 includes a first silo 11 and a stirring assembly 12, which is rotatably mounted within first silo 11. Inoculation system 2 includes an inoculation tube 21, which is connected to first silo 11 and disposed along a secant of the rotational trajectory of stirring assembly 12. The connection between inoculation tube 21 and first silo 11 corresponds to stirring assembly 12. Stirring assembly 12 is used at least to transport bacterial strains into inoculation tube 21.

[0035] When using the single-row, multi-position, adaptive constant-pressure inoculation device of this embodiment, the fungus to be inoculated is stored in the first silo 11, and the logs to be inoculated are installed in corresponding inoculation tubes 21. Before inoculation, the stirring assembly 12 rotates, causing the fungus in the first silo 11 to follow the movement, preventing clogging. Simultaneously, the fungus is transported into the inoculation tube 21, ensuring that the fungus inoculation tube 21 is full or nearly full with each inoculation. This improves the consistency of the inoculated fungus amount across multiple inoculations, thereby beneficially affecting the yield and quality of the edible fungi.

[0036] Example 2

[0037] On the basis of the first embodiment, the stirring assembly 12 includes a first blade 121 and a second blade. The first blade 121 and the second blade are coaxially arranged, and the angle between the extension direction of the first blade 121 and the extension direction of the second blade is greater than 0° and less than or equal to 90°. The first blade 121 is arranged at the feed port of the first silo 11, and the second blade is arranged at the connecting port between the first silo 11 and the inoculation tube 21. When the fungus enters the first silo 11, it needs to pass through the rotation trajectory of the first blade 121. At this time, the first blade 121 can break up the clumps of fungus entering the first silo 11, thereby improving the uniformity of the fungus. The fungus broken up by the first blade 121 is then loaded into the inoculation tube 21 by the second blade, so that the internal structure of the fungus inoculated into the log by the inoculation tube 21 is uniform, which is conducive to reducing the difference in the quality of edible fungi grown from the fungus.

[0038] It should be noted that the first blade 121 and the second blade can be driven by a driving member such as a rotary cylinder, a motor, etc., and this embodiment does not limit this.

[0039] Preferably, the first blade 121 is columnar, which is beneficial for reducing the resistance of the bacteria to the first blade 121 when the first blade 121 breaks up the bacteria; the second blade is sheet-shaped, which is beneficial for the second blade to transport the bacteria to the inoculation tube 21.

[0040] As an optional embodiment, the second paddle includes a supporting surface 1221. The normal of the supporting surface 1221 is perpendicular to the diameter of the second paddle's rotational trajectory. The edge of the supporting surface 1221 facing away from the first paddle 121 abuts against the wall of the first silo 11, where the communication port is located. When the second paddle rotates, the edge of the supporting surface 1221 abuts against the wall of the first silo 11, driving the bacterial strain located on the side of the communication port within the first silo 11 to move and ultimately enter the inoculation tube 21. This reduces dead angles within the first silo 11 and helps prevent the bacterial strain from deteriorating due to long-term retention within the first silo 11.

[0041] As an optional embodiment, the inoculation system 2 also includes a sleeve 22, a piston 23, and a valve plate 24. The sleeve 22 is connected to the first silo 11 and is arranged corresponding to the stirring assembly 12. The inoculation tube 21 is slidably arranged inside the sleeve 22 and is connected to the first silo 11 through the connecting port between the sleeve 22 and the first silo 11. The piston 23 is slidably arranged on the inoculation tube 21. The valve plate 24 is arranged at the end of the inoculation tube 21. The valve plate 24 is used to close when the pressure on the valve plate 24 is less than a threshold value and to open when the pressure on the valve plate 24 is greater than or equal to the threshold value. Before inoculation, the stirring assembly 12 rotates to fill the inoculation tube 21 with bacteria. At this time, the pressure on the valve plate 24 is less than the threshold value, and the valve plate 24 remains closed, which helps prevent the bacteria from spilling out of the inoculation tube 21. During inoculation, the inoculation tube 21 and the piston 23 slide axially along the sleeve 22 until the edge of the inoculation tube 21 contacts the edge of the inoculation hole on the log. The inoculation tube 21 stops moving. At this time, the piston 23 continues to move, cooperating with the closed valve plate 24 to compact the bacteria in the inoculation tube 21 until the pressure on the valve plate 24 reaches a threshold value. The piston 23 continues to move so that the compacted bacteria enter the inoculation hole of the log to complete the inoculation. The magnitude of the pressure on the bacteria is the threshold value. Since the inoculation tube 21 continues to move toward the log before contacting the surface of the log, the single-row, multi-position adaptive constant pressure inoculation device of this embodiment can adapt to logs of different diameters and complete the inoculation. At the same time, the valve plate 24 makes the bacteria in the inoculation tube 21 subject to a pressure of the threshold value and then inoculated into the log, achieving the purpose of constant pressure, which is conducive to making the internal structure of the bacteria inoculated into the log by the inoculation tube 21 uniform and reducing the difference in the quality of edible fungi grown from the bacteria.

[0042] Optionally, there are multiple valve discs 24, and the valve disc 24 may be fan-shaped, with its arc portion hinged to the edge of the inoculation tube 21. As a preferred embodiment, the central angle of the valve disc 24 is less than or equal to 120°.

[0043] Furthermore, a torsion spring or other elastic member is installed at the hinge between the valve disc 24 and the inoculation tube 21, and a limit structure is provided on the inoculation tube 21 to prevent the valve disc 24 from folding into the inoculation tube 21. By controlling the elastic modulus of the torsion spring or other elastic member and the size of the preload force, the purpose of adjusting the threshold value can be achieved.

[0044] As an optional embodiment, the inoculation system 2 further includes a first driver 25 and a position sensor. The first driver 25 is connected to the piston 23. The position sensor is provided corresponding to the piston 23, and the position sensor signal is connected to the first driver 25. The position sensor can identify the position of the piston 23 and, therefore, whether the inoculation process is complete. After the inoculation is completed, the first driver 25 can stop driving the piston 23 to prevent the piston 23 from affecting the inoculated strain. For example, the position sensor can be a magnetic switch, a photoelectric switch, etc., which is again not limited in this embodiment.

[0045] As an optional embodiment, the feeding system 1 also includes a second silo 13, which is connected to the feed port of the first silo 11. The volume of the second silo 13 is larger than that of the first silo 11, and the second silo 13 is used to supply bacterial strains to the first silo 11. Since the first silo 11 is provided with a stirring assembly 12, in order to avoid excessive resistance when the stirring assembly 12 rotates, the first silo 11 needs to limit its volume, thereby limiting the amount of bacterial strains contained therein. By providing a second silo 13 with a volume larger than that of the first silo 11, the second silo 13 continuously supplies bacterial strains to the first silo 11, which can reduce the frequency of adding bacterial strains to the single-row, multi-position adaptive constant pressure inoculation device of this embodiment, thereby improving inoculation efficiency. Moreover, unlike the connection between the inoculation tube 21 and the first silo 11, which is limited by the diameter of the inoculation tube 21, the connection between the first silo 11 and the second silo 13 is less restricted, and a connection with a larger cross-sectional area can be used to connect the first silo 11 and the second silo 13 to avoid blockage.

[0046] As an optional embodiment, it further includes a clamping system 3, which is arranged corresponding to the inoculation tube 21 and is used to clamp and / or rotate the wood segment.

[0047] As an optional embodiment, the clamping system 3 includes: a second driving member 31, a clamp 32 and a motion control component 33. The second driving member 31 is connected to the motion control component 33, and the clamp 32 is connected to the motion control component 33 or the second driving member 31. The motion control component 33 is used to control the motion state of the clamp 32. The clamp 32 is driven by the second driving member 31 to rotate, thereby rotating the log so that the inoculation holes on different sides of the log are aligned with the inoculation tube 21. The motion control component 33 can stop the clamp 32 from rotating when it rotates to the appropriate angle. The single-row, multi-position adaptive constant pressure inoculation device of this embodiment can reduce manual intervention in the process of strain inoculation, which is conducive to saving labor and improving inoculation efficiency.

[0048] The second driving member 31 may be any motor that is convenient for controlling the rotation angle; the motion control component 33 may be a cam divider or an angular displacement sensor, etc., which is not limited in this embodiment.

[0049] As an optional embodiment, a mounting frame 4 is further included. The mounting frame 4 includes a horizontal beam 41 and two longitudinal beams 42. The two longitudinal beams 42 are arranged in parallel. The ends of the horizontal beam 41 are respectively connected to the ends of the two longitudinal beams 42 on the same side. The feeding system 1 and the inoculation system 2 are mounted on the horizontal beam 41, and the clamping system 3 is mounted on the longitudinal beam 42. The mounting frame 4 of this embodiment has a door-like structure, which facilitates the installation of a conveyor belt or other conveying device under the horizontal beam 41 to transport the logs, which is beneficial for improving the efficiency of inoculating large quantities of logs with fungus.

[0050] As an optional embodiment, there are multiple inoculation systems 2, and the multiple inoculation systems 2 are arranged along the extension direction of the beam 41. The multiple inoculation systems 2 of this embodiment can simultaneously inoculate multiple inoculation holes in the same row on the same log, which is conducive to improving inoculation efficiency.

[0051] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0052] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
