Description

Technical Field

[0001] The invention belongs to the field of inoculation machinery, in particular to an automatic bacterial strain inoculation machine. Background Art

[0002] The strains in the strain inoculation usually refer to the microbial populations used to cultivate edible fungi, such as mushrooms and shiitake mushrooms. They are the key factors in the production process of edible fungi, and inoculation is the process of putting the strains into the fungus bags.

[0003] In the prior art, during the process of inoculating the strains, an automatic strain inoculator is often used to inoculate the strain bags. The automatic strain inoculator inserts injection tubes into the strain bags in batches, and then the injection tubes are used to pass the strains into the strain bags, thereby completing the inoculation of the strains.

[0004] In the prior art, when inserting the injection tube into the fungus bag, the culture soil inside the fungus bag may enter the injection tube, causing the tube mouth inside the injection tube to be blocked, or culture soil may remain at the tube mouth and cause the injection tube to be contaminated, which is not conducive to the normal inoculation of the strain.

[0005] To this end, the present invention provides an automatic bacterial strain inoculation machine. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the automatic inoculator of bacterial strains described in the present invention comprises a shell; a feed port is provided at one end of the shell; a conveying assembly is installed at one end of the shell near the feed port; the conveying assembly is used to convey the bacterial bags to be inoculated; a support frame is fixedly connected to the top surface of the shell; a cleaning assembly is slidably connected to the bottom surface of the support frame; the cleaning assembly is used to clean the bacterial bags to be inoculated; a pair of hydraulic rods are fixedly connected to the bottom surface of the support frame, and the hydraulic rods are located on the side of the cleaning assembly away from the feed port of the shell; the telescopic ends of the two hydraulic rods are commonly fixedly connected to a connecting plate; a plurality of evenly arranged insert tubes are fixedly connected to the bottom surface of the connecting plate; an insertion rod is provided at the bottom of the insert tube; and the insertion rod is connected to the insert tube A connecting assembly is installed between the two ends; the connecting assembly is used to connect the plug rod and the plug tube, and allows the plug rod to be away from and close to the end of the plug tube; the bottom and top ends of the plug rod are both conically arranged; the bottom surface of the connecting plate is fixedly connected to an electromagnet on one side of the plug tube, and the plug tube and the plug rod are both made of magnetizable metal; the electromagnet is in contact with the plug tube; the plug tube is connected to an external feeding assembly; the external feeding assembly is used to pump the bacteria into the plug tube; a discharge port is provided on the side surface of the shell away from the feed port; a discharge device is installed at the discharge port inside the shell; the discharge device is used to discharge the inoculated bacteria bag from the discharge port; when working, when batch inoculation of the bacteria bag can be used, the embodiment of the present invention can be used, first the user needs to put The inoculated bacteria bag is placed on the conveying component from the feed inlet, and the conveying component then moves the bacteria bag to the bottom of the cleaning component. The cleaning component then cleans and disinfects the top surface of the bacteria bag, and then sends the bacteria bag to the connecting plate at the bottom of the support frame. The hydraulic rod then starts to push the connecting plate, the cannula and the rod to the surface of the bacteria bag that has just been cleaned. Then the conical structure at the bottom of the rod can smoothly pierce the surface plastic bag of the bacteria bag. During this process, the electromagnet is always in the on state, so that the rod and the cannula fit tightly together. When the rod is fully inserted into the bacteria bag, the electromagnet is closed. At this time, the hydraulic rod drives the rod to rise through the connecting plate. At this time, since the electromagnet is closed, the cannula can no longer absorb the rod, so that relative sliding occurs between the rod and the cannula The hydraulic rod drives the cannula to press against the rod through the connecting plate, so that the end of the cannula fits the surface of the rod. At this time, the electromagnet is started, and the rod adsorbs the rod. Then the hydraulic rod drives the cannula and the rod to rise through the connecting plate, and then the rod and the cannula are completely pulled out of the cannula. In this way, the gap between the cannula and the rod will be opened only when the bacteria need to be discharged, thereby avoiding the culture soil in the cannula from clogging the cannula, or the cannula is contaminated by too much culture soil remaining in the cannula.

[0008] Preferably, the connecting assembly includes a connecting tube; the bottom surface of the connecting tube is fixedly connected to the top side surface of the insertion rod; the top surface of the connecting tube is slidably connected to the inner wall of the insertion tube; the surface of the connecting tube is provided with a plurality of evenly arranged discharge ports; during operation, when the bacteria need to be discharged from the insertion tube, the electromagnet will be powered off, the insertion tube will no longer be able to adsorb the insertion rod, the hydraulic rod will drive the insertion tube to rise, and the insertion rod will remain stationary under its own gravity and the squeeze of the surrounding culture soil, and the insertion tube will slide relative to the connecting tube, so that the connecting tube is exposed in the gap between the insertion tube and the insertion rod, and the bacteria in the insertion tube will be evenly discharged into the culture soil inside the fungus bag through the discharge ports evenly arranged on the surface of the connecting tube, thereby improving the germination rate of the bacteria.

[0009] Preferably, a guide tube is fixedly connected to the surface of the connecting tube at a position corresponding to the discharge outlet; the guide tube is located on the inner side of the insertion tube; during operation, after the bacteria are sprayed out from the discharge outlet, the bacteria will enter the guide tube, and the guide tube will guide the bacteria to be sprayed out along the guide tube, so as to prevent some bacteria from sliding along the outer wall of the connecting tube, thereby causing the bacteria to stick to the outer wall of the connecting tube, thereby causing some bacteria to be unable to enter the culture soil inside the bacteria bag, thereby causing a waste of bacteria.

[0010] Preferably, a pressure plate is provided at the bottom of the connecting plate; a through hole is provided on the surface of the pressure plate at the corresponding position of the insertion tube; a pair of telescopic rods are fixedly connected between the bottom surface of the connecting plate and the top surface of the pressure plate; moving blocks are installed on both sides of the inner wall of the shell on the pressure plate; the surfaces of the opposite sides of the two moving blocks are provided with mounting grooves; a limiting block is slidably connected in the mounting groove, and the end of the limiting block away from the bottom of the mounting groove is arranged in an arc shape; a spring 2 is fixedly connected between the limiting block and the bottom of the mounting groove; during operation, when the connecting plate pushes the insertion tube and the insertion rod to insert into the interior of the mushroom bag, the connecting plate will also push the pressure plate through the telescopic rod, and this telescopic rod is in a compressed state. During this process, the two ends of the pressure plate will contact the limit blocks on the surface of the moving block, thereby pressing the limit block into the mounting groove and compressing the spring 2 , so that the pressing plate can move to the bottom surface of the limit block. At this time, since the end of the pressing plate no longer squeezes the limit block, the spring 2 is restored and the limit block is pushed out of the installation groove, thereby blocking the pressing plate. In this process, the cannula can normally pass through the through hole on the surface of the pressing plate to be inserted into the mushroom bag. When the hydraulic rod drives the connecting plate to rise, the connecting plate rises and stretches the telescopic rod. When the insertion rod and the insertion tube are completely pulled out of the mushroom bag, the stretching fluid of the telescopic tube reaches the maximum stretching stroke. At this time, the connecting plate continues to rise and drives the pressing plate through the telescopic rod to squeeze the limit block again, so that the pressing plate can move to the top surface of the limit block, thereby completing the reset operation. In the process of pulling out the cannula, the pressing plate is always pressed on the top surface of the mushroom bag, thereby reducing the amount of culture soil of the mushroom bag brought out by the insertion rod after the insertion rod is pulled out, thereby reducing waste.

[0012] Preferably, the side wall of the through hole is fixedly connected with a plurality of uniformly arranged pressing plates; the plurality of pressing plates form an annular structure, and the pressing plates are made of elastic sheet material; the diameter of the bottom of the annular structure formed by the plurality of pressing plates is adapted to the outer diameter of the insert tube; during operation, when the pressing plate is pressed on the top surface of the mushroom bag, the pressing plate at the side wall of the through hole on the surface of the pressing plate will also be pressed on the edge of the insertion rod or the insert tube, thereby pressing the culture soil at the insertion point of the insert rod, avoiding a large amount of culture soil being brought out when the insert rod and the insert tube are pulled out, resulting in a waste of culture soil.

[0013] Preferably, the conveying assembly includes a partition; the partition is fixed inside the shell and is located at the bottom of the insertion rod; the surface of the partition is rotatably connected to drive rollers near the two ends; a pair of drive belts are sleeved between the two drive rollers, and the two drive belts are respectively located at the two ends of the drive rollers; a receiving tray is commonly fixedly connected between the two drive belts, and the receiving tray is arranged in a U-shaped structure; during operation, when the user needs to transport the mushroom bag through the conveying assembly, the user needs to place the mushroom bag on the top surface of the receiving tray, and then the driving roller rotates, and drives the driving belt to move together, and then the driving belt drives the receiving tray to move, thereby realizing the transportation of the mushroom bag, and because the cross-section of the receiving tray is arranged in a U-shape, it can prevent the mushroom bag from rolling randomly during the transportation of the mushroom bag, which causes the insertion tube and the insertion rod to fail to be inserted into the mushroom bag normally.

[0014] Preferably, the conveying assembly includes a guide rail; the guide rail is fixedly connected to the top surface inside the shell and is located at the discharge port; the bottom surface of the guide rail is slidably connected to a push plate; the push plate is fixedly connected to a push rod at one end away from the discharge port, and the push rod is U-shaped; the push rod is fixedly connected to a scraper at one end away from the push plate, and the scraper is located between two driving rollers; during operation, when the inoculation of the mushroom bag is completed, the receiving plate will transport the inoculated mushroom bag to the discharge port, at which time the push plate on the bottom surface of the guide rail will push one end of the mushroom bag, thereby pushing the mushroom bag out of the discharge port, and thus completing the unloading operation of the mushroom bag, and then the push plate moves toward the inside of the shell again to complete the resetting of the push plate, and in the process of the reciprocating motion of the push plate, the push plate will also drive the scraper to move back and forth through the push rod, thereby scraping the top surface of the partition, so that the culture soil dropped by the mushroom bag during transportation gathers on both sides of the partition, which is convenient for the user to clean it.

[0015] Preferably, the bottom surface of the receiving disk is rotatably connected to a plurality of rollers; the rotating axes of the rollers and the rotating axes of the driving rollers are perpendicular to each other; during operation, when the push plate pushes the mushroom bag toward the discharge port, the mushroom bag will drive the rollers on the surface of the receiving disk to rotate, thereby reducing the friction force when the mushroom bag moves, making it easier for the mushroom bag to detach from the surface of the receiving disk, and when the receiving disk moves driven by the driving belt, the rollers cannot rotate. At this time, the rollers serve to increase the maximum static friction force to reduce the shaking of the mushroom bag during movement.

[0016] Preferably, waste slag openings are provided on both sides of the partition; a slag outlet is provided at one end of the shell; a waste slag box is slidably connected to the shell at the slag outlet; during operation, when the scraper sweeps the culture soil to both sides of the partition, the scraper will sweep the culture soil to the waste slag openings on both sides of the partition, and then the culture soil will fall into the waste slag box from the waste slag opening, and then the user can pull the waste slag box out of the slag outlet, so as to recycle and reuse the culture soil in the waste slag box.

During the process of pulling out the insertion tube, the pressure plate is always pressed on the top surface of the bacteria bag, thereby reducing the amount of culture soil of the bacteria bag brought out by the insertion rod after the insertion rod is pulled out, thereby reducing waste.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 5As shown, an automatic inoculator for bacterial strains according to an embodiment of the present invention comprises a shell 1; a feed port 2 is provided at one end of the shell 1; a conveying assembly is installed at one end of the shell 1 near the feed port 2; the conveying assembly is used to convey the bacterial bag to be inoculated; a support frame 3 is fixedly connected to the top surface of the shell 1; a cleaning assembly 4 is slidably connected to the bottom surface of the support frame 3; the cleaning assembly 4 is used to clean the bacterial bag to be inoculated; a pair of hydraulic rods 5 are fixedly connected to the bottom surface of the support frame 3, and the hydraulic rods 5 are located on the side of the cleaning assembly 4 away from the feed port 2 of the shell 1; the telescopic ends of the two hydraulic rods 5 are commonly fixedly connected to a connecting plate 6; a plurality of uniformly arranged inserts 7 are fixedly connected to the bottom surface of the connecting plate 6; an insert rod 8 is provided at the bottom of the insert 7 ; A connecting assembly is installed between the insertion rod 8 and the insertion tube 7; the connecting assembly is used to connect the insertion rod 8 and the insertion tube 7, and allows the insertion rod 8 to be away from and close to the end of the insertion tube 7; the bottom and top ends of the insertion rod 8 are both conical; the bottom surface of the connecting plate 6 is fixedly connected to an electromagnet 9 on one side of the insertion tube 7, and the insertion tube 7 and the insertion rod 8 are both made of magnetizable metal; the electromagnet 9 is in contact with the insertion tube 7; the insertion tube 7 is connected to an external feeding assembly; the external feeding assembly is used to pump the bacteria into the insertion tube 7; a discharge port 10 is provided on the side surface of the shell 1 at one end away from the feed port 2; a discharge device is installed at the discharge port 10 inside the shell 1; the discharge device is used to send the inoculated bacteria bag out of the discharge port 10;During operation, when the mushroom bags are inoculated in batches, the embodiment of the present invention can be used. First, the user needs to place the mushroom bags to be inoculated on the conveying assembly from the feed port 2, and then the conveying assembly will move the mushroom bags to the bottom of the cleaning assembly 4. Then the cleaning assembly 4 will clean and disinfect the top surface of the mushroom bags, and then the mushroom bags will be sent to the connecting plate 6 at the bottom of the support frame 3. After that, the hydraulic rod 5 is started to push the connecting plate 6, the insertion tube 7 and the insertion rod 8 to the surface of the mushroom bags that have just been cleaned. Then the conical structure at the bottom of the insertion rod 8 can smoothly pierce the surface plastic bag of the mushroom bags. During this process, the electromagnet 9 is always in the on state, so that the insertion rod 8 and the insertion tube 7 are tightly fitted together. When the insertion rod 8 is fully inserted into the interior of the mushroom bag, the electromagnet 9 is turned off. At this time, the hydraulic rod 5 drives the insertion rod 8 to rise through the connecting plate 6. At this time, since the electromagnet 9 is turned off, the insertion tube 7 can no longer absorb the insertion rod 8. The insertion rod 8 and the insertion tube 7 will slide relative to each other, so that a gap will appear between the insertion rod 8 and the insertion tube 7. At this time, the external feeding assembly can feed the bacteria into the insertion tube 7, and then enter the inside of the bacteria bag through the gap between the insertion tube 7 and the insertion rod 8, thereby completing the inoculation operation of the bacteria bag. When the bacteria enter the inside of the bacteria bag, the hydraulic rod 5 will drive the insertion tube 7 to press against the insertion rod 8 through the connecting plate 6, so that the end of the insertion tube 7 and the surface of the insertion rod 8 fit together. At this time, the electromagnet 9 is started, and the insertion rod 8 will adsorb the insertion rod 8. Then the hydraulic rod 5 drives the insertion tube 7 and the insertion rod 8 to rise through the connecting plate 6, and then the insertion rod 8 and the insertion tube 7 are completely pulled out of the bacteria bag. In this way, the gap between the insertion tube 7 and the insertion rod 8 will be opened only when the bacteria need to be discharged, thereby avoiding the culture soil in the bacteria bag from clogging the insertion tube 7, or the insertion tube 7 is contaminated by too much culture soil remaining in the insertion tube 7. ;

[0032] like Figures 3 to 5 As shown, the connecting assembly includes a connecting tube 11; the bottom surface of the connecting tube 11 is fixedly connected to the top side surface of the insertion rod 8; the top surface of the connecting tube 11 is slidably connected to the inner wall of the insertion tube 7; the surface of the connecting tube 11 is provided with a plurality of evenly arranged discharge ports 12; during operation, when the bacteria need to be discharged from the insertion tube 7, the electromagnet 9 will be powered off, the insertion tube 7 will no longer be able to adsorb the insertion rod 8, the hydraulic rod 5 will drive the insertion tube 7 to rise, and the insertion rod 8 will remain motionless under its own gravity and the squeeze of the surrounding culture soil, and the insertion tube 7 will slide relative to the connecting tube 11, so that the connecting tube 11 is exposed in the gap between the insertion tube 7 and the insertion rod 8, and at this time the bacteria in the insertion tube 7 will be evenly discharged into the culture soil inside the fungus bag through the discharge ports 12 evenly arranged on the surface of the connecting tube 11, thereby improving the germination rate of the bacteria.

[0033] like Figures 4 to 5As shown, a guide tube 13 is fixedly connected to the surface of the connecting tube 11 at a position corresponding to the discharge port 12; the guide tube 13 is located on the inner side of the insert tube 7; during operation, after the bacteria are sprayed out from the discharge port 12, the bacteria will enter the guide tube 13, and the guide tube will guide the bacteria to be sprayed out along the guide tube 13, so as to prevent some bacteria from sliding along the outer wall of the connecting tube 11, thereby causing the bacteria to stick to the outer wall of the connecting tube 11, thereby causing some bacteria to be unable to enter the culture soil inside the bacteria bag, thereby causing bacteria waste.

[0034] like Figure 3 and Figure 6 As shown, a pressing plate 14 is provided at the bottom of the connecting plate 6; a through hole 15 is provided on the surface of the pressing plate 14 at the corresponding position of the insertion tube 7; a pair of telescopic rods 16 are fixedly connected between the bottom surface of the connecting plate 6 and the top surface of the pressing plate 14; moving blocks 18 are installed on the inner wall of the shell 1 on both sides of the pressing plate 14; the surfaces of the two opposite sides of the two moving blocks 18 are provided with mounting grooves 19; a limiting block 20 is slidably connected in the mounting groove 19, and the end of the limiting block 20 away from the bottom of the mounting groove 19 is arranged in an arc shape; a spring 21 is fixedly connected between the limiting block 20 and the bottom of the mounting groove 19; during operation, when the connecting plate 6 pushes the insertion tube 7 and the insertion rod 8 to be inserted into the interior of the mushroom bag, the connecting plate 6 will also push the pressing plate 14 through the telescopic rod 16, and this telescopic rod 16 is in a compressed state. During this process, the two ends of the pressing plate 14 will contact the limiting blocks 20 on the surface of the moving block 18, thereby pressing the limiting blocks 20 into the mounting groove 19, and The compression spring 21 allows the pressure plate 14 to move to the bottom surface of the limit block 20. At this time, since the end of the pressure plate 14 no longer squeezes the limit block 20, the spring 21 recovers and pushes the limit block 20 out of the mounting groove 19, thereby blocking the pressure plate 14. During this process, the cannula 7 can normally pass through the through hole 15 on the surface of the pressure plate 14 to be inserted into the interior of the mushroom bag. When the hydraulic rod 5 drives the connecting plate 6 to rise, the connecting plate 6 rises and stretches the telescopic rod 16. When the insertion rod 8 and the cannula 7 are completely pulled out of the mushroom bag, the stretching fluid of the telescopic tube reaches the maximum stretching stroke. At this time, the connecting plate 6 continues to rise and drives the pressure plate 14 through the telescopic rod 16 to squeeze the limit block 20 again, so that the pressure plate 14 can move to the top surface of the limit block 20, thereby completing the reset operation. In the process of pulling out the cannula 7, the pressure plate 14 is always pressed on the top surface of the mushroom bag, thereby reducing the amount of culture soil of the mushroom bag brought out by the insertion rod 8 after the insertion rod 8 is pulled out, thereby reducing waste.

[0035] like Figure 1 , Figure 2 and Figure 7As shown, a bolt 22 is fixedly connected to the surface of the moving block 18; a slide groove 23 is opened at the corresponding position of the surface of the shell 1 and the moving block 18, and the bolt 22 passes through the slide groove 23; the surface of the bolt 22 located outside the shell 1 is threadedly connected with a nut 24; during operation, when the user inoculates bacteria bags of different diameters again, the user can screw the nut 24 to release the lock of the moving block 18, so that the user can slide the bolt 22 and the moving block 18 and make it slide along the slide groove 23. When the moving seat and the limit block 20 on the surface reach the appropriate position, that is, the pressure plate 14 is at the bottom surface of the limit block 20, and the bottom surface of the pressure plate 14 can just press on the top surface of the bacteria bag, the user can re-tighten the nut 24 to fix the position of the moving block 18. By adjusting the position of the moving block 18, the extrusion position of the pressure plate 14 can be adjusted to adapt to bacteria bags of different diameters, thereby improving the scope of application of the embodiment of the present invention.

[0036] like Figure 3 and Figure 6 As shown, the side wall of the through hole 15 is fixedly connected with a plurality of uniformly arranged pressing sheets 25; the plurality of pressing sheets 25 form an annular structure, and the pressing sheets 25 are made of elastic sheet material; the diameter of the bottom of the annular structure formed by the plurality of pressing sheets 25 is adapted to the outer diameter of the insert tube 7; during operation, when the pressing plate 14 is pressed on the top surface of the mushroom bag, the pressing plate 14 at the side wall of the through hole 15 on the surface of the pressing plate 14 will also be pressed on the edge of the insertion rod 8 or the insert tube 7, thereby pressing the culture soil at the insertion point of the insert rod 8, avoiding that a large amount of culture soil is brought out when the insert rod 8 and the insert tube 7 are pulled out, resulting in waste of culture soil.

[0037] like Figure 1 , Figure 2 and Figure 8 As shown, the conveying assembly includes a partition 26; the partition 26 is fixed inside the shell 1 and is located at the bottom of the insertion rod 8; the surface of the partition 26 is rotatably connected to a driving roller 27 near the two ends; a pair of driving belts 28 are sleeved between the two driving rollers 27, and the two driving belts 28 are respectively located at the two ends of the driving roller 27; a receiving plate 29 is commonly fixedly connected between the two driving belts 28, and the receiving plate 29 is set in a U-shaped structure; during operation, when the user needs to transport the mushroom bag through the conveying assembly, the user needs to place the mushroom bag on the top surface of the receiving plate 29, and then the driving roller 27 rotates and drives the driving belt 28 to move together, and then the driving belt 28 drives the receiving plate 29 to move, thereby realizing the transportation of the mushroom bag, and because the cross-section of the receiving plate 29 is set in a U-shape, it can prevent the mushroom bag from rolling randomly during the transportation of the mushroom bag, which causes the insertion tube 7 and the insertion rod 8 to fail to be inserted into the mushroom bag normally.

[0038] like Figure 1 , Figure 2 and Figure 8As shown, the conveying assembly includes a guide rail 30; the guide rail 30 is fixedly connected to the top surface inside the shell 1 and is located at the discharge port 10; the bottom surface of the guide rail 30 is slidably connected to a push plate 31; the push plate 31 is fixedly connected to the end away from the discharge port 10, and the push rod 32 is U-shaped; the push rod 32 is fixedly connected to the end away from the push plate 31, and the scraper 33 is located between the two driving rollers 27; when working, when the mushroom bag is inoculated, the receiving plate 29 will transport the inoculated mushroom bag to the discharge port 1 0, at this time, the push plate 31 on the bottom of the guide rail 30 will push one end of the mushroom bag, thereby pushing the mushroom bag out from the discharge port 10, and then completing the unloading operation of the mushroom bag, and then the push plate 31 moves toward the inside of the shell 1 to complete the reset of the push plate 31. During the reciprocating motion of the push plate 31, the push plate 31 will also drive the scraper 33 to move back and forth through the push rod 32, thereby scraping the top surface of the partition 26, so that the culture soil dropped by the mushroom bag during transportation is gathered on both sides of the partition 26, which is convenient for the user to clean it.

[0039] like Figure 2 and Figure 8 As shown, the bottom surface of the receiving plate 29 is rotatably connected to a plurality of rollers 34 that are uniformly arranged; the rotation axis of the rollers 34 is perpendicular to the rotation axis of the driving roller 27; during operation, when the pushing plate 31 pushes the mushroom bag toward the discharge port 10, the mushroom bag will drive the rollers 34 on the surface of the receiving plate 29 to rotate, thereby reducing the friction force when the mushroom bag moves, making it easier for the mushroom bag to detach from the surface of the receiving plate 29, and when the receiving plate 29 moves driven by the driving belt 28, the rollers 34 cannot rotate. At this time, the rollers 34 play a role in increasing the maximum static friction force to reduce the shaking of the mushroom bag during movement.

[0040] like Figure 1 , Figure 2 and Figure 8 As shown, waste slag openings 35 are provided on both sides of the partition 26; a slag outlet 36 is provided at one end of the shell 1; a waste slag box 37 is slidably connected to the slag outlet 36 inside the shell 1; during operation, when the scraper 33 sweeps the culture soil to both sides of the partition 26, the scraper 33 will sweep the culture soil to the waste slag openings 35 on both sides of the partition 26, and then the culture soil will fall into the waste slag box 37 from the waste slag openings 35, and then the user can pull the waste slag box 37 out of the slag outlet 36, so as to recycle and reuse the culture soil in the waste slag box 37.

[0041] During operation, when the mushroom bags are inoculated in batches, the embodiment of the present invention can be used. First, the user needs to place the mushroom bags to be inoculated on the conveying assembly from the feed port 2, and then the conveying assembly will move the mushroom bags to the bottom of the cleaning assembly 4. Then the cleaning assembly 4 will clean and disinfect the top surface of the mushroom bags, and then the mushroom bags will be sent to the connecting plate 6 at the bottom of the support frame 3. After that, the hydraulic rod 5 is started to push the connecting plate 6, the insertion tube 7 and the insertion rod 8 to the surface of the mushroom bags that have just been cleaned. Then the conical structure at the bottom of the insertion rod 8 can smoothly pierce the surface plastic bag of the mushroom bags. During this process, the electromagnet 9 is always in the on state, so that the insertion rod 8 and the insertion tube 7 are tightly fitted together. When the insertion rod 8 is fully inserted into the interior of the mushroom bag, the electromagnet 9 is turned off. At this time, the hydraulic rod 5 drives the insertion rod 8 to rise through the connecting plate 6. At this time, since the electromagnet 9 is turned off, the insertion tube 7 can no longer absorb the insertion rod 8. When the bacteria enter the bag, the hydraulic rod 5 drives the pipe 7 to press against the rod 8, so that the end of the pipe 7 fits the surface of the rod 8. At this time, the electromagnet 9 is started, and the rod 8 adsorbs the rod 8. Then the hydraulic rod 5 drives the pipe 7 and the rod 8 to rise through the connecting plate 6, and then the rod 8 and the pipe 7 are completely pulled out of the bag. In this way, the gap between the pipe 7 and the rod 8 is opened only when the bacteria need to be discharged, thereby avoiding the culture soil in the bag from clogging the pipe 7, or causing the pipe 7 to be contaminated by too much culture soil remaining in the pipe 7.

[0042] When it is necessary to discharge the bacteria from the insert tube 7, the electromagnet 9 will be powered off, the insert tube 7 will no longer be able to absorb the insertion rod 8, the hydraulic rod 5 will drive the insert tube 7 to rise, and the insertion rod 8 will remain motionless under its own gravity and the squeeze of the surrounding culture soil, and the insert tube 7 will slide relative to the connecting tube 11, so that the connecting tube 11 is exposed in the gap between the insert tube 7 and the insertion rod 8. At this time, the bacteria in the insert tube 7 will be evenly discharged into the culture soil inside the fungus bag through the discharge ports 12 evenly arranged on the surface of the connecting tube 11, thereby improving the germination rate of the bacteria.

[0043] After the bacteria are sprayed out from the discharge port 12, they will enter the guide tube 13 and be guided by the guide tube to spray out along the guide tube 13, so as to prevent some bacteria from sliding along the outer wall of the connecting tube 11, thereby causing the bacteria to stick to the outer wall of the connecting tube 11, thereby causing some bacteria to be unable to enter the culture soil inside the bacteria bag, thereby causing waste of bacteria.

[0044] When the connecting plate 6 pushes the insertion tube 7 and the insertion rod 8 to be inserted into the interior of the mushroom bag, the connecting plate 6 will also push the pressing plate 14 through the telescopic rod 16, and the telescopic rod 16 is in a compressed state. During this process, the two ends of the pressing plate 14 will contact the limit blocks 20 on the surface of the moving block 18, thereby pressing the limit blocks 20 into the installation groove 19 and compressing the spring 21, so that the pressing plate 14 can move to the bottom surface of the limit blocks 20. At this time, since the end of the pressing plate 14 no longer squeezes the limit blocks 20, the spring 21 recovers and pushes the limit blocks 20 out of the installation groove 19, thereby blocking the pressing plate 14. During this process, the insertion tube 7 can pass through the pressing plate normally. The through hole 15 on the surface of 14 is inserted into the interior of the mushroom bag, and when the hydraulic rod 5 drives the connecting plate 6 to rise, the connecting plate 6 rises and stretches the telescopic rod 16. When the insertion rod 8 and the insertion tube 7 are completely pulled out of the mushroom bag, the stretching fluid of the telescopic tube reaches the maximum stretching stroke. At this time, the connecting plate 6 continues to rise, and drives the pressing plate 14 through the telescopic rod 16 to squeeze the limit block 20 again, so that the pressing plate 14 can move to the top surface of the limit block 20, thereby completing the reset operation. In the process of pulling out the insertion tube 7, the pressing plate 14 is always pressed on the top surface of the mushroom bag, thereby reducing the amount of culture soil of the mushroom bag brought out by the insertion rod 8 after the insertion rod 8 is pulled out, thereby reducing waste.

[0045] When the user inoculates mushroom bags of different diameters again, the user can screw the nut 24 to release the lock on the moving block 18, allowing the user to slide the bolt 22 and the moving block 18 and make it slide along the slide groove 23. When the moving seat and the limit block 20 on the surface reach the appropriate position, that is, the pressure plate 14 is at the bottom of the limit block 20, and the bottom of the pressure plate 14 can just press on the top surface of the mushroom bag, the user can screw the nut 24 again to fix the position of the moving block 18. By adjusting the position of the moving block 18, the extrusion position of the pressure plate 14 can be adjusted to adapt to mushroom bags of different diameters, thereby improving the scope of application of the embodiment of the present invention.

[0046] When the pressing plate 14 is pressed on the top surface of the mushroom bag, the pressing plate 14 at the side wall of the through hole 15 on the surface of the pressing plate 14 will also be pressed on the edge of the insertion rod 8 or the insertion tube 7, thereby pressing the culture soil at the insertion point of the insertion rod 8, avoiding that a large amount of culture soil is taken out when the insertion rod 8 and the insertion tube 7 are pulled out, causing waste of culture soil.

[0047] When the user needs to transport the mushroom bag through the conveying assembly, the user needs to place the mushroom bag on the top surface of the receiving tray 29, and then the driving roller 27 rotates and drives the driving belt 28 to move together, and then the driving belt 28 drives the receiving tray 29 to move, thereby realizing the transportation of the mushroom bag. Since the cross-section of the receiving tray 29 is U-shaped, it can prevent the mushroom bag from rolling randomly during the transportation process, which will cause the insertion tube 7 and the insertion rod 8 to fail to be inserted into the mushroom bag normally.

[0048] When the inoculation of the mushroom bag is completed, the receiving tray 29 will transport the inoculated mushroom bag to the discharge port 10. At this time, the push plate 31 on the bottom of the guide rail 30 will push one end of the mushroom bag, thereby pushing the mushroom bag out of the discharge port 10, and then completing the unloading operation of the mushroom bag. Then the push plate 31 moves toward the inside of the shell 1 to complete the reset of the push plate 31. During the reciprocating motion of the push plate 31, the push plate 31 will also drive the scraper 33 to move back and forth through the push rod 32, thereby scraping the top surface of the partition 26, so that the culture soil dropped by the mushroom bag during transportation gathers on both sides of the partition 26, which is convenient for the user to clean it.

[0049] When the push plate 31 pushes the mushroom bag toward the discharge port 10, the mushroom bag will drive the roller 34 on the surface of the receiving plate 29 to rotate, thereby reducing the friction when the mushroom bag moves, making it easier for the mushroom bag to detach from the surface of the receiving plate 29. When the receiving plate 29 moves driven by the driving belt 28, the roller 34 cannot rotate. At this time, the roller 34 serves to increase the maximum static friction to reduce the shaking of the mushroom bag during movement.

[0050] When the scraper 33 sweeps the culture soil to both sides of the partition 26, the scraper 33 will sweep the culture soil to the waste residue openings 35 on both sides of the partition 26, and then the culture soil will fall into the waste residue box 37 from the waste residue openings 35. Then the user can pull the waste residue box 37 out of the residue outlet 36, so as to recycle and reuse the culture soil in the waste residue box 37.
