Description

Technical Field

[0001] This invention relates to the field of mushroom stick inoculation technology, specifically to an integrated automatic pressing inoculation device for mushroom stick pits. Background Technology

[0002] Mushroom substrate inoculation is a processing step in cultivating edible fungi. Mushroom substrate is a culture medium formed by scientifically mixing agricultural and forestry by-products such as cottonseed hulls, sawdust, and corn cobs, and then placing it in a specially made plastic bag. During this process, the cultivated edible fungi spawn (mother spawn or original spawn) is inoculated into the pre-set inoculation holes in the prepared mushroom substrate or by making incisions to inoculate the mycelium. Currently, most inoculation methods are manual, which is inefficient and can easily pollute the inoculation environment, affecting the subsequent growth of edible fungi. The scale of mass cultivation is limited, and the output is not good enough.

[0003] In view of this, a design or technical improvement is proposed to address the above-mentioned problems.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an integrated automatic pressing and inoculation device for mushroom sticks.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An integrated automatic pressing and inoculation device for mushroom log pits includes a frame for mounting components. The frame includes feet for supporting the entire device, support rods mounted on the feet, and a fixing plate assembly fixed to the end of the support rods away from the feet.

[0008] The fixed plate assembly is connected to a movable plate that slides vertically up and down on a support rod via a piston cylinder.

[0009] An inoculation mechanism for pressing indentations on the mushroom sticks and injecting bacterial spores is also provided between the fixed plate group and the movable plate;

[0010] With the movable plate in a raised or lowered state, the inoculation mechanism presses the inoculum stick and injects the inoculum.

[0011] Furthermore, the inoculation mechanism includes a material storage section, a pushing section disposed on the material storage section, and a puncture needle disposed on the pushing section for puncturing the membrane.

[0012] Furthermore, the storage section includes a storage cylinder for absorbing materials, a conveying hose connected to the storage cylinder, and a one-way valve installed on the conveying hose.

[0013] Furthermore, the ejector section includes an ejector assembly disposed on the storage cylinder and a backflow preventer assembly disposed between the storage section and the puncture needle.

[0014] Furthermore, the ejection assembly includes a piston cylinder that communicates with the storage cylinder and is fixed to the movable plate, and a piston rod that slides and seals within the piston cylinder. An energy storage spring is provided between the piston cylinder and the piston rod.

[0015] Furthermore, the fixed plate assembly is also provided with a limiting component for limiting the piston rod and a triggering component for controlling the limiting component to release the piston rod.

[0016] Furthermore, the fixing plate assembly includes a lower frame plate and an upper frame plate, and the limiting component is disposed on the upper frame plate;

[0017] The limiting assembly includes a first fixing frame, an annular protrusion plate disposed on the piston rod, and a latching arm that limits sliding within the first fixing frame. A wedge-shaped surface is provided between the annular protrusion plate and the latching arm to cooperate with each other.

[0018] Furthermore, the triggering component includes a suspension arm disposed on the lower frame plate, a first locking block that limits sliding within a first movable groove opened on the suspension arm, a first spring with one end disposed on the suspension arm and the other end disposed on the first locking block, a fixed sleeve disposed on the piston cylinder, a second locking block that limits sliding within the fixed sleeve, and a second spring with one end disposed on the fixed sleeve and the other end disposed on the second locking block.

[0019] A third spring is also provided between the buckle arm and the first fixing frame, and the buckle arm passes through the limiting slide groove opened on the suspension arm and connects to the first buckle block. Both the first buckle block and the second buckle block are provided with a downward-facing wedge-shaped surface.

[0020] Furthermore, the anti-reverse assembly includes a jet tube communicating with the storage cylinder, a blocking plate abutting against the communication port between the storage cylinder and the jet tube, and a fourth spring with one end disposed on the jet tube and the other end disposed on the blocking plate.

[0021] Furthermore, the puncture needle is also provided with a circumferential groove, and a rubber bladder that seals and covers the outside of the circumferential groove is also provided on the circumferential groove.

[0022] The jet tube is also provided with a movable cavity groove, and a push rod is also provided in the movable cavity groove. The push rod slides in a sealed manner in the movable cavity groove. A fifth spring is also provided between the push rod and the movable cavity groove. The movable cavity groove is connected to the annular cutting groove through an air passage provided in the wall of the jet tube and the puncture needle.

[0023] A base plate is also fixedly installed on the support rod, and an abutment cylinder is also provided on the base plate, which is sleeved on the outside of the jet tube. The end of the thrust rod relative to the abutment cylinder is hemispherical.

[0024] Compared with existing technologies, the advantages of this solution are: this equipment can automate the inoculation of mushroom sticks, avoiding environmental pollution and low efficiency in the manual inoculation process, and greatly increasing production.

[0025] This equipment utilizes a single power source to achieve an integrated pressing and inoculation process. Its instantaneous transmission through mechanical structure enhances the continuity of the process, improves inoculation accuracy, and mitigates the step-time control deviation caused by the multi-threaded control of the pressing and inoculation structures by multiple power sources.

[0026] After the film of the mushroom stick is punctured and pressed, this device can lift the outer film when the inoculum is injected, so that it is separated from the culture medium. This prevents the film from contaminating the inoculum during the injection process and avoids additional damage to the puncture hole, resulting in better integrity of the film after the mushroom stick is injected.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figure 1-15 The illustrated integrated automatic inoculation device for mushroom logs includes a frame 1 for mounting components. The frame 1 includes a base 11 for supporting the entire device, a support rod 12 mounted on the base 11, and a fixed plate assembly 13 fixed to the end of the support rod 12 away from the base 11. The fixed plate assembly 13 is connected to a movable plate 15 that slides vertically up and down on the support rod 12 via a piston cylinder 14. An inoculation mechanism 2 for pressing indentations on the mushroom logs and injecting spawn is also provided between the fixed plate assembly 13 and the movable plate 15. When the movable plate 15 is in the up and down state, the inoculation mechanism 2 presses the mushroom logs and injects spawn. The frame 1 serves as the supporting structure for the entire device, the base 11 serves as the basic mounting support, and the movable plate 15 is fixed by a sliding sleeve mounted on the support rod 12, allowing it to slide on the support rod 12. The up and down movement of the movable plate 15 drives the inoculation mechanism 2 to complete the pressing and spawn injection.

[0046] In one embodiment, the inoculation mechanism 2 includes a storage section 21, a pushing section 22 disposed on the storage section 21, and a puncture needle 23 disposed on the pushing section 22 for piercing the membrane. The storage section 21 is used to absorb and temporarily store the inoculum. Then, the inoculation mechanism 2 uses the puncture needle 23 to pierce the outer membrane of the inoculum stick to allow it to enter the culture medium. Then, the pushing section 22 is used to push the inoculum in the storage section 21 into the pit of the culture medium to complete the inoculation.

[0047] In one embodiment, the storage unit 21 includes a storage cylinder 211 for absorbing the inoculum, a delivery hose 212 communicating with the storage cylinder 211, and a one-way valve 213 provided on the delivery hose 212. The delivery hose 212 is connected to the device for storing inoculum. Through the operation of the injection unit 22, the inoculum is drawn into the storage cylinder 211 through the delivery hose 212, and then sprayed into the mushroom stick through the puncture needle 23. Since the inoculum needs to be injected again after being drawn into the storage cylinder 211, the one-way valve 213 is provided on the delivery hose 212 to prevent part of the inoculum from being sent back into the delivery hose 212 during the injection process.

[0048] In one embodiment, the injection section 22 includes an injection component 221 disposed on the storage cylinder 211 and a backflow preventer 222 disposed between the storage section 21 and the puncture needle 23. The injection component 221 mainly performs the work of aspirating and injecting bacteria, while the backflow preventer 222 is used to prevent the injection component 221 from drawing air into the storage cylinder 211 through the puncture needle 23 during the process of aspirating bacteria.

[0049] In one embodiment, the ejector assembly 221 includes a piston cylinder 2211 communicating with the storage cylinder 211 and fixed on the movable plate 15, and a piston rod 2212 that slides and seals within the piston cylinder 2211. An energy storage spring 2213 is provided between the piston cylinder 2211 and the piston rod 2212. The piston cylinder 2211 and the piston rod 2212 are movable relative to each other. In the initial state of the device, the piston rod 2212 is fixed on the fixed plate assembly 13, while the piston cylinder 2211 moves up and down under the drive of the movable plate 15. When moving downwards, the piston rod 2212 is pulled inside, which in turn draws in the inoculum through the conveying hose 212. Since the two ends of the energy storage spring 2213 are fixed to the piston cylinder 2211 and the piston rod 2212 respectively, when the two are pulled away, the energy storage spring 2213 will also deform and store energy. Then, after the piston rod 2212 is released from the fixed plate assembly 13, it can push the inoculum in the storage cylinder 211 through the energy release of the energy storage spring 2213.

[0050] In one embodiment, the fixed plate assembly 13 is further provided with a limiting component 223 for limiting the piston rod 2212 and a triggering component 224 for controlling the limiting component 223 to release the piston rod 2212. In the initial state of the device, the piston rod 2212 is fixed on the fixed plate assembly 13 by the limiting component 223. Therefore, when the piston cylinder 2211 moves downward, the piston rod 2212 remains stationary, so that the two can perform relative movement to realize the work of pulling and pushing the bacterial culture. Because the piston cylinder 2211 moves downward a certain distance, the puncture needle set at the lower end is... After puncturing the film of the puncture needle 23 and pressing a pit into the culture medium, it needs to be pulled back to keep the puncture needle 23 at a certain distance from the culture medium and stabilize it, thereby completing the injection. Through the setting of the trigger component 224, the piston cylinder 2211 will use the trigger component 224 to control the limiting component 223 to contact the limiting of the piston rod 2212 after pulling back a certain distance. Under the restoring force of the energy storage spring 2213, the piston rod 2212 is pulled into the piston cylinder 2211, thereby pushing the inoculum out of the puncture needle 23 to complete the injection.

[0051] In one embodiment, the fixing plate assembly 13 includes a lower frame plate 131 and an upper frame plate 132, and a limiting component 223 is disposed on the upper frame plate 132. The limiting component 223 includes a first fixing frame 2231, an annular protrusion 2232 disposed on the piston rod 2212, and a latching arm 2233 that limits sliding within the first fixing frame 2231. A wedge-shaped surface is provided between the annular protrusion 2232 and the latching arm 2233 to cooperate with each other. The limiting component 223 limits the piston rod 2212 specifically by utilizing the latching arm. 2233 is fastened and fixed to the annular protrusion 2232, so that the piston rod 2212 always remains in the original position during the downward movement of the piston cylinder 2211. Since the annular protrusion 2232 and the latching arm 2233 are provided with mutually cooperating wedge-shaped surfaces, after the piston rod 2212 is released from the limit and an injection is completed, when the piston cylinder 2211 moves upward and drives the piston rod 2212 upward, the two sets of wedge-shaped surfaces abut against each other, which will push the latching arm 2233 outward and slide, thus not affecting the reset of the piston rod 2212.

[0052] In one embodiment, the triggering component 224 includes a suspension arm 2241 disposed on the lower mounting plate 131, a first locking block 2243 that slides within a first movable groove 2242 formed in the suspension arm 2241, a first spring 2244 with one end disposed on the suspension arm 2241 and the other end disposed on the first locking block 2243, a fixing sleeve 2245 disposed on the piston cylinder 2211, a second locking block 2246 that slides within the fixing sleeve 2245, and a second spring with one end disposed on the fixing sleeve 2245 and the other end disposed on the second locking block 2246. A third spring 2248 is also provided between the latching arm 2233 and the first fixed frame 2231. The latching arm 2233 passes through the limiting groove 2249 opened on the suspension arm 2241 and connects to the first locking block 2243. Both the first locking block 2243 and the second locking block 2246 are provided with downward-facing wedge-shaped surfaces. The triggering component 224 is designed to contact the limiting component 223 to limit the piston rod 2212 when the piston cylinder 2211 moves back a certain distance, so that it can complete the injection. Its main working principle is... The principle is that during the retraction of piston cylinder 2211, the second locking block 2246 at its upper end will abut against the first locking block 2243, causing it to drive the locking arm 2233 to move outward, thereby causing the locking arm 2233 to misalign with the annular protrusion 2232, thus releasing piston rod 2212. However, during the downward movement of piston cylinder 2211, the second locking block 2246 at its outer end will initially abut against the first locking block 2243. At this time, because injection is not required, the restriction on piston rod 2212 cannot be released. Therefore, to prevent the first locking block 2246 from being released... 3 is abutted and retracted by the second locking block 2246, thus both are provided with wedge-shaped surfaces, and the wedge-shaped surfaces are both facing downwards. When the second locking block 2246 moves downwards and passes the first locking block 2243, the second locking block 2246 will be abutted and retracted by the first locking block 2243, so as not to affect the upper limiting component 223's limiting of the piston rod 2212. At the same time, when the piston cylinder 2211 moves back, it can also be abutted and retracted by the second locking block 2246 against the first locking block 2243, so that the limiting component 223 contacts the limiting of the piston rod 2212.

[0053] In one embodiment, the anti-reverse component 222 includes a jet tube 2221 communicating with the storage cylinder 211, a blocking plate 2222 abutting against the communication port between the storage cylinder 211 and the jet tube 2221, and a fourth spring 2223 with one end on the jet tube 2221 and the other end on the blocking plate 2222. When the piston rod 2212 pushes the bacteria in the piston cylinder 2211, the blocking plate 2222 will move under pressure, so that the communication port between the storage cylinder 211 and the jet tube 2221 opens, and then the bacteria will enter the jet tube 2221 and be injected out. After the injection is completed, the blocking plate 2222 will be reset under the action of the fourth spring 2223, thereby sealing the communication port.

[0054] In one embodiment, the puncture needle 23 is further provided with an annular groove 231, and a rubber bladder 232 sealingly covering its outer side is also provided on the annular groove 231; the jet tube 2221 is further provided with a movable cavity groove 233, and a push rod 234 is also provided in the movable cavity groove 233. The push rod 234 slides in a sealed manner in the movable cavity groove 233, and a fifth spring 235 is also provided between the push rod 234 and the movable cavity groove 233. The movable cavity groove 233 is connected to the annular groove 231 through an air passage 236 that penetrates the walls of the jet tube 2221 and the puncture needle 23; a base plate 237 is also fixedly provided on the support rod 12, and a sleeve is provided on the base plate 237 that fits onto the jet tube 2221. The outer abutment cylinder 238 and the push rod 234 are hemispherical at one end relative to the abutment cylinder 238. After the puncture needle 23 punctures into the film of the mushroom stick, it needs to be pulled back a certain distance to lift the film and separate it from the culture medium, thereby avoiding contamination during the injection of the inoculum. Since the traditional method of lifting the film is to use the raised texture or barbs on the outer surface of the needle to lift the film, this method of pulling the film is prone to causing additional damage at the puncture site. Therefore, this device sets a ring groove 231 on the puncture needle 23 and sets a rubber bladder 232 in the ring groove 231. The outer surface of the rubber bladder 232 does not exceed the surface of the ring groove 231. Then, on the jet cylinder 2221 A movable cavity 233 is provided, which is connected to the annular groove 231 via an air passage 236. When the puncture needle 23 punctures the membrane, the jet tube 2221 drives the push rod 234 to slide into the contact tube 238. The inner wall of the contact tube 238 then abuts against the push rod 234, moving it into the movable cavity 233. This injects gas from the movable cavity 233 into the annular groove 231 via the air passage 236, causing the rubber capsule 232 to inflate. When the puncture needle 23 is pulled back, the inflated rubber capsule 232 helps the membrane detach from the culture medium surface. After the puncture needle 23 has moved a certain distance back, the push rod 234 will... The tube 238 disengages, and under the action of the fifth spring 235, the push rod 234 resets, causing the gas in the annular groove 231 to be drawn back into the movable cavity groove 233, which restores the rubber bladder 232. Thus, the puncture needle 23 can be pulled out from the membrane. It is worth noting that there are several ways to set the air passage 236 on the puncture needle 23. For example, the wall of the puncture needle can be thickened to a certain extent to facilitate the opening of the air passage 236 in its wall, or a plastic layer can be set on the outer wall of the puncture needle 23, and the air passage 236 can be set between the plastic layer and the wall. All of these methods will not affect the puncture and inoculation effect of the puncture needle 23, and can be designed and used according to the actual production situation.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
