Detailed Implementation

[0022] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 6 As shown, a fungus cultivation and inoculation device of this utility model includes a clamping and rotating mechanism, a telescopic punching mechanism 6 and a telescopic liquid injection mechanism 3. The telescopic punching mechanism 6 is provided on one side of the clamping and rotating mechanism, and the telescopic liquid injection mechanism 3 is provided on the other side of the clamping and rotating mechanism. The clamping and rotating mechanism includes a base 7, a rotating drive, a rotating tray 5, and a rotating pressing assembly. The rotating tray 5 is rotatably connected to the middle of the base 7. The rotating drive is driven to the rotating tray 5. The rotating pressing assembly is disposed above the rotating tray 5 and is connected to the base 7. The telescopic punching mechanism 6 is disposed on one side of the base 7, and the telescopic liquid injection mechanism 3 is disposed on the other side of the base 7.

[0024] The working principle of this utility model is as follows: In actual production and use, when it is necessary to punch holes in the mushroom bag for inoculation, the mushroom bag can be placed on the rotating tray 5 first. Then, the rotating pressing component is operated to press and fix the top of the mushroom bag. Then, the telescopic punching mechanism 6 is operated to punch a row of holes in the mushroom bag. Then, the rotating drive component is operated to make the rotating tray 5 and the rotating pressing component work together to drive the mushroom bag to rotate appropriately, so that the unpunched part of the mushroom bag moves to the telescopic punching mechanism 6 for punching. As the mushroom bag rotates, the punched part rotates to the telescopic injection mechanism 3. Then, the telescopic injection mechanism 3 is operated to insert into the punched hole to inject the bacterial liquid. Then, the mushroom bag is removed.

[0025] Furthermore, the rotating pressing assembly includes a frame 8, a first linear drive 2, a lifting component 1, and a pressure plate 9. The lower part of the frame 8 is connected to the base 7, the first linear drive 2 is connected to the upper part of the frame 8, the first linear drive 2 is linearly driven connected to the upper part of the lifting component 1, and the pressure plate 9 is rotatably connected to the lower part of the lifting component 1. The pressure plate 9 is located directly above the rotating tray 5.

[0026] As can be seen from the above description, when it is necessary to fix the mushroom bag, the first linear drive 2 can be operated, so that the first linear drive 2 drives the pressure plate 9 to press the top of the mushroom bag through the lifting component 1, thereby fixing the mushroom bag through the cooperation of the pressure plate 9 and the rotating tray 5, which facilitates the subsequent rotation of the mushroom bag.

[0027] Furthermore, the telescopic punching mechanism 6 includes a first bracket 601, a first moving member 604, a second linear drive member 603, and a plurality of punching assemblies 605. The first bracket 601 is fixedly connected to one side of the base 7. The second linear drive member 603 is detachably connected to the first bracket 601 and is linearly driven connected to one side of the first moving member 604. A first sliding groove is provided on the other side of the first moving member 604. A plurality of punching assemblies 605 are arranged from top to bottom on the first sliding groove. The punching assemblies 605 are detachably connected to the first moving member 604.

[0028] As can be seen from the above description, when it is necessary to punch holes in the mushroom bag, the second linear drive 603 can be operated, so that the second linear drive 603 drives several punching components 605 to move towards the mushroom bag through the first moving component 604 to make several holes, which facilitates subsequent inoculation.

[0029] Furthermore, the punching assembly 605 includes a punching needle 6051, a screw 6055, a nut 6054, and a rubber washer 6053. The screw 6055 passes through the first groove, and one side of the screw 6055 is provided with a thread. The nut 6054 is detachably connected to the thread, and the other side of the screw 6055 is provided with a nut 6052. The punching needle 6051 is fixedly connected to the nut on the side away from the nut 6054. The nut 6052 and the nut 6054 are both provided with the rubber washer 6053 on the side near the first groove.

[0030] As can be seen from the above description, when it is necessary to adjust the distance between the holes on the mushroom bag, the perforating needle 6051 can be released from the clamping force with the first sliding groove by the screw 6055 and nut 6054, thereby sliding the perforating needle 6051 and adjusting it to a suitable position. After the position is adjusted, the nut 6054 can be turned towards the nut 6052 by the screw 6055, so that the rubber gasket 6053 on the nut 6054 and nut 6052 contacts and clamps with both sides of the first sliding groove.

[0031] Furthermore, the telescopic injection mechanism 3 includes a second support 301, a second moving part 313, a third linear drive part 307, several injection components, a storage tank 309, a pressure pump 308, and a main flow pipe 305. The second support 301 is fixedly connected to the other side of the base 7. The third linear drive part 307 is detachably connected to the second support 301 and linearly driven connected to one side of the second moving part 313. A second sliding groove is provided on the other side of the second moving part 313. One side of the injection component is slidably connected to the second sliding groove and detachably connected to the second moving part 313. The other side of each injection component is connected to the main flow pipe 305. The main flow pipe 305 is connected to the inside of the storage tank 309 through the pressure pump 308.

[0032] As can be seen from the above description, when it is necessary to inject bacteria into the punched holes, the punched position on the bag can be moved to the position of the telescopic injection mechanism 3 by the clamping and rotating mechanism. Then, the third linear drive 307 is operated, so that the injection component is aligned with the hole and inserted into the hole. Then, the pressure pump 308 is operated, so that the pressure pump 308 draws the bacterial liquid in the storage box 309 into the hole for injection. Then, the third linear drive 307 is operated to reset, waiting for the injection of the next row of holes.

[0033] Furthermore, the injection assembly includes an injection tube 312, a magnetic suction element 310, an inlet tube 302, a flow valve 303, and a diversion tube 304. The injection tube 312 passes through the second groove, with one end of the injection tube 312 serving as the injection end. The other end of the injection tube 312 is externally provided with the magnetic suction element 310. The other side of the second moving part 313 is provided with an adsorbed piece 311. The magnetic suction element 310 is detachably connected to the adsorbed piece 311. The other end of the injection tube 312 is connected to one end of the flow valve 303 through the inlet tube 302. The other end of the flow valve 303 is connected to the main flow tube 305 through the diversion tube 304.

[0034] As can be seen from the above description, when the injection position needs to be adjusted, the magnetic suction force of the magnetic suction component 310 can be released, so that the magnetic suction component 310 is separated from the adsorbed piece 311. Then, the position of the injection tube 312 in the second slide groove can be adjusted. After the adjustment is completed, the magnetic suction component 310 is operated so that the magnetic suction component 310 adsorbs and fixes the adsorbed piece. When a certain amount of bacterial solution needs to be injected into the hole, the flow rate of the flow valve 303 can be adjusted to adjust the injection metering. During injection, the bacterial solution flows into the inside of the diversion tube 304 through the main flow tube 305. Then, the diversion tube 304 injects the bacterial solution into the hole through the inlet tube 302 and the injection tube 312.

[0035] Furthermore, both the first movable component 604 and the second movable component 313 are provided with scale markings.

[0036] As can be seen from the above description, when it is necessary to adjust the injection position of the injection tube 312 according to the puncture position, the position of the injection tube 312 can be adjusted according to the position of the puncture needle 6051 on the scale, so as to better align the injection hole.

[0037] Furthermore, rubber anti-slip pads 4 are provided on the opposite sides of the rotating tray 5 and the pressure plate 9.

[0038] As can be seen from the above description, the rubber anti-slip pad 4 helps to increase the friction between the mushroom bag and the rotating tray 5 and the pressure plate 9, thereby better driving the mushroom bag to rotate.

[0039] Furthermore, it also includes a PLC controller, which is electrically connected to the clamping and rotating mechanism, the telescopic piercing mechanism 6, and the telescopic liquid injection mechanism 3, respectively.

[0040] As can be seen from the above description, it is beneficial to adjust the parameters of the mushroom cultivation inoculation device through the PLC controller, and to make it more convenient for operators to operate the mushroom cultivation inoculation device. Example 1
