Description

Technical Field

[0001] This utility model relates to the field of edible fungi production equipment technology, and in particular to a portable mobile punching device for edible fungi bags. Background Technology

[0002] Edible fungi are an excellent source of nutrition, rich in protein with a balanced amino acid composition, and have high nutritional value. During the cultivation of edible fungi, in order to ensure the quality of the mushrooms, it is necessary to punch holes in the mushroom bags to promote mycelial color change and growth. The traditional manual punching method is not only labor-intensive and inefficient, but also results in holes of varying sizes and depths, which is not conducive to the uniform respiration and color change of the mycelium, making it difficult to guarantee the quality and yield of edible fungi.

[0003] To address the aforementioned situation, Chinese utility model patent CN208095482U discloses a perforation device for oyster mushroom spawn bags. This device includes a support, a platform for fixing the spawn bags below the support, and a cylinder positioned above the support. A lifting plate is connected to the movable end of the cylinder, and multiple perforation needles are positioned below the lifting plate. A guide plate is provided between the perforation needles and the platform. The cylinder has an inlet valve and an outlet valve, and is also connected to a pneumatic switch via a pipe. This oyster mushroom spawn bag perforation device requires no electricity, is pneumatically driven, and uses the cylinder to drive the perforation needles to make holes of uniform size and depth, reducing the risk of infection during inoculation.

[0004] The aforementioned mushroom bag punching device has some shortcomings. On the one hand, the device is fixed in position and inconvenient to move, requiring manual handling of the mushroom bags. After punching, the mushroom bags need to be handled again to the cultivation rack, which cannot meet the requirement of directly placing the mushroom bags on the rack after punching. Moreover, the mushroom bags are easily damaged during handling, affecting mycelial growth. On the other hand, the device still uses traditional rigid punching. The impact force applied at the moment of punching cannot be buffered by the mushroom bags, which can easily cause the mushroom bags to break, resulting in the exposure of the culture medium and increasing the risk of contamination by other microorganisms. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is: the frequent handling during the punching of edible mushroom bags, resulting in low efficiency and the problem that rigid punching can easily cause the mushroom bags to break.

[0006] The technical solution of this utility model is as follows:

In this technical solution, the sliding conveyor mechanism is connected to the punching device to directly transport the punched edible mushroom bags to the bag cultivation rack. The punching device is connected above the walking mechanism via the lifting device, which allows adjustment of the height of the punching device to adapt to punching needs in different scenarios. The walking mechanism provides mobility for the entire device, making it portable and easy to move between different edible mushroom cultivation sites.

[0008] Based on the above solutions, the preferred technical solution for the portable edible mushroom bag perforation machine is a wheeled walking mechanism.

Subsequently, the punching assembly punches holes in the clamped and fixed mushroom bag.

[0012] Based on the above solution, as a preferred technical solution for a portable mobile punching machine for edible mushroom bags, the clamping mechanism includes two clamping blocks connected to the main body via a drive device. The clamping blocks are symmetrically arranged, with their opposing surfaces being arc-shaped and having holes. Each clamping block contains a cavity adapted to the punching assembly. This technical solution provides the shape and structure of the clamping device. The opposing surfaces of the clamping blocks are arc-shaped, a design that matches the cylindrical appearance of the edible mushroom bag, allowing for better contact with the bag surface, improving clamping stability, and preventing damage to the bag during clamping. The holes on the arc-shaped surfaces of the clamping blocks allow the punching needle to punch holes in the bag when the clamping blocks clamp it. Each clamping block contains a cavity to accommodate the punching assembly, with the length and width of the cavity slightly larger than the corresponding dimensions of the needle plate. The drive device can be a hydraulic cylinder, pneumatic cylinder, or motor to drive the two clamping blocks to move relative to each other, achieving clamping and releasing of the mushroom bag.

[0013] Based on the above solution, as a preferred technical solution for a portable mobile punching machine for edible mushroom bags, the punching assembly includes a needle plate, punching needles for punching, and a second driving device for driving the needle plate.

A spring is connected between the punching needles and the needle plate to buffer the impact of punching. One end of the second driving device is connected to the main body, and the other end is connected to the needle plate. This technical solution provides the structure and position of the punching assembly. The punching assembly is arranged in the cavity of the clamping block and connected via guide rods welded to the clamping block. The guide rods at both ends of the needle plate in the punching assembly guide the movement of the assembly, ensuring that the punching assembly moves smoothly along a preset direction, preventing the punching needles from deviating during punching, and ensuring the accuracy of the punching position. The springs effectively buffer the impact during punching, preventing damage to the internal structure of the mushroom bag or the punching needles themselves due to excessive impact, while also reducing vibration impact on other parts of the equipment and extending the service life of the equipment. The second drive unit can be a hydraulic cylinder, a pneumatic cylinder, or a motor. When the second drive unit drives the drilling assembly to move, it achieves efficient and stable drilling operation under the guidance of the guide rod and the buffering effect of the spring.

This technical solution provides the structure of the sliding conveying mechanism, where the conveying chute delivers the perforated edible mushroom bags to the cultivation rack; the baffle prevents the edible mushroom bags from falling off the conveying chute when they reach the cultivation rack, ensuring a smooth and stable conveying process.

[0015] Based on the above solution, as a preferred technical solution for a portable mobile perforation machine for edible mushroom bags, the conveying chute is a three-section chute, with grooves and matching sliders. The chute sections are connected by grooves and sliders. This technical solution provides the structure of the conveying chute and the connection method between the chute sections. The chute is equipped with sliders and grooves, and the connection between the chute sections allows for expansion and contraction adjustment according to actual needs. During use, the chute can be extended to meet requirements, and at the end of perforation, the chute can be retracted for easy storage.

[0016] Based on the above solution, as a preferred technical solution for a portable edible mushroom bag perforation machine, one end of the conveyor slide is hinged to the perforation device, and the other end is hinged to the baffle. This technical solution provides the connection position and method of the conveyor slide. The hinged connection allows the conveyor slide to rotate relative to the perforation device, facilitating the adjustment of the conveying angle to adapt to different placement positions and conveying needs. Simultaneously, the hinge between the conveyor slide and the baffle allows the baffle to adjust its angle according to actual conditions, better preventing it from falling off.

[0017] Compared with existing technologies, the portable edible mushroom bag punching device proposed in this invention solves the problems of frequent handling, low efficiency, and easy breakage of mushroom bags caused by rigid punching. With this portable edible mushroom bag punching device, the device can be flexibly applied to any location on the mushroom bag cultivation rack via the walking mechanism at the bottom. After punching the mushroom bags, the bags can slide directly onto the cultivation rack via the conveyor track on the device, reducing manual handling and preventing damage to the bags during manual handling, thus improving work efficiency.

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] The specific implementation method is as follows:

[0030] A portable mobile punching machine for edible mushroom bags, such as Figures 1 to 7 As shown, the device includes a punching device 3 connected to a sliding conveyor mechanism 2, which is connected above the walking mechanism 1 via a lifting device 4. In this embodiment, the overall structure of the punching machine revolves around the walking mechanism 1, forming an integrated device that combines movement, lifting, conveying, and punching functions. In actual use, the operator can push the device through the walking mechanism 1 to the storage area of ​​the edible mushroom bags 17, manually move the edible mushroom bags 17 to the punching device, and after punching, use the sliding conveyor mechanism 2 to transport the punched bags to the cultivation rack 18. This saves the operator the process of moving the bags back and forth and reduces damage to the edible mushroom bags 17 during handling.

[0031] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the walking mechanism 1 is a wheeled walking mechanism. This embodiment provides a type of walking mechanism. This choice is mainly due to the fact that wheeled structures are more flexible when moving on flat or slightly undulating planting sites, are lighter and less expensive than tracked structures, and in practical applications, operators can easily push the equipment to move inside or outside the greenhouse to meet the punching needs in different locations.

[0032] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the wheeled walking mechanism includes a base 7 and a wheel set for movement. The wheel set includes four omnidirectional wheels, at least two of which are equipped with brake components. This embodiment provides the specific composition of the wheeled walking mechanism. The base 7 of the wheeled walking mechanism is made of steel plate or alloy plate, and a power supply 8 for providing power to the device and a tool box 19 for repairing parts are provided on the base 7. The power supply 8 is connected to the motor and other devices of the electric lifting device through wires. The wheel set uses four omnidirectional wheels, of which the two omnidirectional wheels located at the front end of the base 7 are equipped with brake components. When the equipment moves to the designated position, stepping on the brake components can lock the omnidirectional wheels to prevent the equipment from sliding during the punching operation and ensure safe and stable operation. When movement is required, releasing the brake components allows for flexible steering and movement.

[0033] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the lower end of the lifting device 4 is connected to the base 7, and the upper end is connected to the punching device 3; the lifting device (4) is a manual lifting device, an electric lifting device, a hydraulic lifting device, or a pneumatic lifting device. This embodiment provides the connection position of the lifting device and several different lifting devices, namely a manual lifting device, an electric lifting device, a hydraulic lifting device, or a pneumatic lifting device; the lower end of the lifting device 4 is fixed to the center position of the base 7 by bolts or welding, and the upper end is also connected to the bottom of the punching device 3 by bolts or welding.

[0034] Specifically, the manual lifting device includes a crank handle, a transmission gear set, a screw, a lifting sleeve, a load-bearing platform, and a base. The crank handle is a model 8866-9000, which can effectively transmit the torque applied by the operator. The transmission gear set uses spur gears, model M2-30T-20W, with a module of 2, 30 teeth, a tooth width of 20mm, and a material of 40Cr, ensuring smooth operation during transmission. The screw is a T-type lead screw, model T20x400, with a thread specification of T20 and a length of 400mm. When meshing with the transmission gear set, it can accurately convert the rotational motion of the gears into its own rotational motion. The lifting sleeve is a lifting sleeve adapted to the T20x400 lead screw, and its internal thread specification is the same as that of the lead screw. A tight fit ensures that the lifting sleeve can move stably along the screw's axial direction when the screw rotates, achieving smooth lifting transmission. The base is welded from Q235 steel plate with a thickness of 10mm and is welded to the base 7. The load-bearing platform is made of 6061-T6 aluminum alloy plate with a thickness of 8mm and is welded to the lifting sleeve. In actual operation, the technician rotates the 8866-9000 model crank handle. The rotation of the crank handle drives the M2-30T-20W model gear set to rotate. The rotation of the gear set is transmitted to the T20x400 model screw, causing the screw to rotate. The rotation of the screw, in turn, causes the matching lifting sleeve to move along the screw's axial direction, thereby driving the load-bearing platform connected to the lifting sleeve to rise and fall, realizing the height adjustment of the drilling device.

[0035] Specifically, the electric lifting device includes a drive motor, a reducer, a lead screw, a nut, a guide device, a control system, a base, and a load-bearing platform. The drive motor is a Y90S-4 three-phase asynchronous motor with a rated power of 1.1kW, a rated speed of 1400r / min, and an IP54 protection rating, providing continuous and reliable power output to the device. The drive motor is paired with an RV63-10 worm gear reducer with a transmission ratio of 10. The input speed is matched with the output speed of the Y90S-4 motor, effectively amplifying the motor's output torque to meet the lifting requirements of the device. Power requirements: The lead screw is a model SFU2005-500 ball screw with a nominal diameter of 20mm, a lead of 5mm, a length of 500mm, and a precision grade of C3, capable of stable rotation under the drive of the reducer; the nut is a model BM2005 nut matched with the SFU2005-500 ball screw, whose internal structure perfectly meshes with the lead screw to ensure smooth linear motion during screw rotation; the guide device uses a model SBR20-500 linear guide rail with a length of 500mm, and is compatible with a model SBR20UU linear guide rail. The slider provides precise guidance for the movement of the load-bearing platform, ensuring stability during lifting and preventing deviation. The control system uses a PLC-S7-200SMART programmable logic controller as its core component, paired with a TP170B touchscreen for human-machine interaction. The base is constructed from 10mm thick Q235 steel plate, welded to the base 7. The load-bearing platform is made of 8mm thick 6061-T6 aluminum alloy plate, welded to the nut. During actual operation, technicians... The PLC-S7-200 SMART control system and TP170B touchscreen activate the Y90S-4 model drive motor. The motor's output torque is amplified by the RV63-10 model reducer to achieve the required torque. The reducer then transmits the motor's torque to the SFU2005-500 model lead screw, causing it to rotate. The rotation of the lead screw drives the BM2005 model nut, which meshes with it, to move linearly. Guided by the SBR20-500 model guide device, the linear motion of the nut drives the 6061-T6 model load-bearing platform to move up and down, thereby achieving the purpose of lifting and lowering the device.

[0036] Specifically, the hydraulic lifting device includes a motor, a hydraulic pump, a hydraulic cylinder, an oil tank, a control system, a control valve group, a load-bearing platform, rubber hoses, and a coupling. The motor is a Y100L1-4 three-phase asynchronous motor with a rated power of 2.2kW, a rated speed of 1430r / min, and an IP55 protection rating, providing sufficient and stable power to the hydraulic pump. The motor is paired with a CB-B25 gear hydraulic pump with a rated pressure of 2.5MPa and a rated flow rate of 25L / min, connected to the Y100L1-4 motor via a coupling. The hydraulic cylinder is a HOB80×300 heavy-duty hydraulic cylinder with a cylinder diameter of 80mm. The cylinder has a stroke of 300mm and a working pressure of 16MPa. The cylinder bottom is welded to the base 7, and the piston rod is welded to the load-bearing platform. The oil tank is a YX-100 hydraulic oil tank with a capacity of 100L, providing sufficient hydraulic oil for the hydraulic system. It is equipped with a level gauge and a filler port for easy observation of the oil level and replenishment of hydraulic oil. The control system uses a PLC-S7-1200 programmable logic controller, combined with a KTP400 touch screen, to accurately control the start and stop of the motor and the action of the control valve group, realizing automated control of the hydraulic lifting device. The control valve group is a 34E1-25B electromagnetic directional valve group, including components such as directional valves and relief valves. The system has a constant pressure of 6.3 MPa, which effectively controls the flow direction, pressure, and flow rate of hydraulic oil, enabling switching between lifting and lowering actions. The load-bearing platform is made of Q345B steel plate with a thickness of 12 mm, welded to the hydraulic cylinder piston rod, allowing for lifting and lowering movements with the piston rod's extension and retraction. The rubber hoses are high-pressure steel wire braided hoses (Φ16×2) with a working pressure of 21 MPa, used for connections between the oil tank and the hydraulic pump, the hydraulic pump and the control valve group, and the control valve group and the hydraulic pump. The coupling is a YL5 flexible pin coupling with a nominal torque of 160 N·m and a shaft hole diameter range of 25-40 mm, reliably connecting the motor and the hydraulic pump, ensuring the smooth operation of both. The devices operate synchronously. In actual operation, technicians use the PLC-S7-1200 control system and KTP400 touchscreen to turn on the Y100L1-4 model motor. The motor drives the CB-B25 model hydraulic pump to draw hydraulic oil from the YX-100 model oil tank through a Φ16×2 high-pressure steel wire braided hose. The hydraulic pump then delivers the hydraulic oil to the 34E1-25B model control valve group through the same hose. The control valve group controls the flow of hydraulic oil, switching the lifting and lowering actions of the device. Subsequently, the hydraulic oil is delivered to the HOB80×300 model hydraulic cylinder, which drives the piston rod of the hydraulic cylinder to extend and retract, causing the Q345B model load-bearing platform welded on the hydraulic cylinder to lift and lower.

[0037] Specifically, the pneumatic lifting device includes an air compressor, control valves, cylinders, a load-bearing platform, a base, and an operating system. The air compressor is a W-0.9 / 8 piston air compressor with a rated discharge capacity of 0.9 m³ / min, a rated working pressure of 0.8 MPa, and a motor power of 5.5 kW, providing a continuous and stable supply of compressed air to the pneumatic system. The control valve is a 4V210-08 solenoid directional valve with a working pressure range of 0.15-0.8 MPa and a nominal diameter of 8 mm, precisely controlling the flow direction of compressed air to switch the cylinder's extension and retraction movements. The cylinder is a standard SC100×300 cylinder with a diameter of 100 mm and a stroke of 3... The cylinder is 00mm thick, with a working pressure of 0.6-0.8MPa. The bottom of the cylinder is connected to the base, and the top of the piston rod is welded to the load-bearing platform, which can stably push the load-bearing platform to complete the lifting movement. The load-bearing platform is made of Q235A steel plate with a thickness of 10mm, which can stably place the equipment to be lifted. The base is made of Q345R steel plate with a thickness of 12mm. The bottom is fixed to the base 7 by welding, providing a solid support foundation for the entire device. The operating system adopts a PLC-S7-200SMART programmable logic controller and a TD400C text display, which can realize the automatic control of the start and stop of the air compressor and the action of the control valve. In actual operation, technicians start the W-0.9 / 8 model air compressor through the PLC-S7-200 SMART operating system and TD400C text display. The compressed air generated by the compressor is delivered to the 4V210-08 model control valve through pipeline. The technicians control the control valve to switch the working state through the operating system, so that the compressed air enters the rod chamber of the SC100×300 model cylinder as needed, pushing the cylinder piston rod to extend and retract, thereby driving the Q235A model load-bearing platform welded to the top of the piston rod to complete the lifting and lowering movement, realizing the lifting and lowering function of the device.

[0038] In this embodiment, the lifting device 4 is an electric lifting device, which includes a small motor, a lead screw and a sleeve. The motor is connected to a foot switch through a wire. The operator can control the forward and reverse rotation of the motor by stepping on the switch, so as to realize the extension and retraction of the lead screw in the sleeve, thereby driving the punching device 3 to rise and fall to meet the punching requirements of mushroom bags of different heights. If used in a place without power, it can also be replaced with a manual lifting device, which can realize the lifting and falling by turning the lead screw with a crank.

[0039] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the punching device 3 includes a main body 22, a clamping mechanism 11 for holding the edible mushroom bag 17, and punching components.

The clamping mechanism 11 is installed in the middle of the main body 22, and the punching components are symmetrically distributed on both sides of the clamping mechanism 11. When the edible mushroom bag 17 is placed in the position of the clamping mechanism 11, the clamping mechanism 11 first fixes it, and then the punching components on both sides simultaneously complete the punching, improving the punching efficiency.

[0040] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the clamping mechanism 11 includes two clamping blocks 12 connected to the main body 22 by a driving device 13. The clamping blocks 12 are symmetrically arranged, and the opposite surfaces are arc-shaped. Holes 25 are provided on the arc-shaped surfaces. A cavity adapted to the punching assembly is provided inside the clamping block 12. This embodiment provides the shape and structure of the clamping device. The driving device 13 of the clamping mechanism 11 can be a pneumatic cylinder of model SC63×50. The cylinders are symmetrically distributed, with four on each side, respectively mounted on the preset mounting seats on both sides of the main body 22. The mounting seats are fixed to the main body 22 by bolts. The bottom of the cylinder barrel is hinged to the mounting seat, and the end of the piston rod is welded to the clamping block 12. The two ends of the connecting parts are respectively engaged with the connecting posts on the piston rod and the clamping block 12 through internal threads to ensure a stable connection. The clamping block 12 is made of nitrile rubber, and the opposite surfaces are processed into an arc shape to match the outer surface of the common cylindrical edible mushroom bag 17. The arc-shaped surface has holes 25, which are distributed in a matrix to allow the punching needle to pass through during punching. The clamping block 12 is provided with a cavity for accommodating the punching component. The cavity is slightly larger than the corresponding size of the needle plate. This is to arrange the punching component in the cavity, and A 5mm gap is reserved to facilitate the movement of the needle plate; the second drive device uses an STMB16×100 cylinder, which is installed at the end of the clamping block 12 away from the arc surface. The cylinder piston rod is fixedly connected to the needle plate of the punching assembly by bolts, providing power for the needle plate to drive the punching needle to move up and down; when the pneumatic cylinder is ventilated, the piston rod of the SC63×50 cylinder of the first drive device extends, driving the clamping block 12 to move towards the center and clamp the edible fungus bag 17. Then, the piston rod of the STMB16×100 cylinder of the second drive device extends, pushing the punching assembly in the cavity to move inward, so that the punching needle passes through the hole 25 and directly punches the edible fungus bag 17; then the cylinder of the second drive device first exhausts air, the piston rod resets and drives the punching assembly back into the cavity. Then the cylinder of the first drive device exhausts air, the piston rod resets, and the clamping block 12 releases the fungus bag. The whole clamping process is stable, and the rubber clamping block 12 can avoid damaging the fungus bag.

[0041] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the punching assembly includes a needle plate 9, a punching needle 20 for punching, and a second driving device 14 for driving the needle plate 9; both ends of the needle plate 9 are connected to the cavity of the clamping block 12 via guide rods 24; the punching needle 20 is located on the side of the needle plate 9 facing the edible mushroom bag 17, and punches holes in the edible mushroom bag 17 through holes 25; a spring 10 for buffering the punching impact is connected between the punching needle 20 and the needle plate 9; one end of the second driving device 14 is connected to the main body 22, and the other end is connected to the needle plate 9. This embodiment provides the structure of the punching assembly. The driving device 2 14 can be an electric push rod, the end of which is fixedly connected to the needle plate 9. The needle plate 9 is made of stainless steel and its size is adapted to the internal cavity of the clamping block 12. Four stainless steel rods are welded to both ends of the clamping block as guide rods 24. The guide rods 24 pass through the guide holes opened on the needle plate 9, so that the needle plate 9 can slide along the axial direction of the guide holes. The punching needles 20 are made of stainless steel. There are 6, 9 or 12 holes evenly distributed on the needle plate 9 for the punching needles 20 to be inserted. These holes correspond to the position and number of holes 25 on the arc surface of the clamping block 12. The number of punching needles 20 on the needle plate can be adjusted according to the number of holes required for the mushroom bag. A compression spring 10 is sleeved between each punching needle 20 and the needle plate 9 to reduce the punching impact force. When the electric push rod pushes the needle plate 9 to move toward the edible mushroom bag 17, the guide rod 24 ensures that the needle plate 9 moves smoothly. The punching needle 20 passes through the hole 25 and contacts the mushroom bag. Then the spring 10 is compressed to buffer the punching impact and prevent the punching needle 20 from penetrating too deeply. After punching, the electric push rod returns to its original position, and the spring 10 drives the punching needle 20 to rebound, completing the punching of the edible mushroom bag 17.

This embodiment provides the structure of the sliding conveying mechanism. The conveying slide 15 of the sliding conveying mechanism 2 can be made of PVC material, which is lightweight and corrosion-resistant. The width of the slide is adapted to the diameter of common edible mushroom bags 17. The baffle 16 is made of silicone material to prevent the bags from falling off the conveying slide when they are conveyed to the cultivation rack.

[0043] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, the conveying chute 15 is a three-section chute, with a groove 21 and a slider 23 adapted to the groove 21. The chute sections are connected by the groove 21 and the slider 23. This embodiment provides the structure of the conveying chute and the connection method between the chute sections. The first section of the chute near the punching device 3 has grooves 21 on both sides. The second section of the chute has sliders 23 adapted to the groove 21 fixed on both sides. The sliders 23 can slide in the groove 21. Similarly, the second and third sections of the chute are also connected by the groove 21 and the slider 23. In use, the three sections of the chute are stretched to the length required to meet the conveying distance of the mushroom bags. When storing, the third section of the chute is slid into the second section of the chute, and then the second section of the chute is slid into the first section of the chute, shortening the total length and facilitating the overall handling and storage of the equipment.

[0044] Based on the above embodiments, as a preferred embodiment of the portable edible mushroom bag punching machine, one end of the conveyor slide 15 is hinged to the punching device 3, and the other end is hinged to the baffle 16. This embodiment provides the connection position and method of the conveyor slide. One end of the conveyor slide 15 is hinged to the side of the punching device 3. The hinged method allows the slide to rotate within the range of 0-90 degrees. The operator can adjust the tilt angle of the slide according to the height of the mushroom bags. For example, when the mushroom bags are stacked at the bottom of the mushroom bag cultivation rack 18, the slide can be tilted to 60 degrees to facilitate the mushroom bags sliding towards the mushroom bag cultivation rack 18 by gravity. The other end of the conveyor slide 15 is hinged to the baffle 16. The baffle 16 can adjust its own angle according to the tilt angle of the slide to always maintain a parallel state with the cultivation rack platform to ensure the anti-falling effect.

[0045] The operation process of this utility model is as follows: First, the operator pushes the portable edible mushroom bag punching machine to move the equipment to the storage area of ​​the edible mushroom bags 17 via the wheel set of the walking mechanism 1. After reaching the designated position, the operator steps on the brake of the universal wheel with brake assembly to fix the equipment and prevent it from sliding during operation. Next, the lifting device 4 is adjusted according to the height requirement of the mushroom bag to be punched. Then, the operator manually moves the edible mushroom bag 17 to the clamping mechanism 11 of the punching device 3. The drive device 13 of the clamping mechanism 11 is activated, driving the two symmetrically arranged clamping blocks 12 to move towards the middle. After the mushroom bag is clamped, the punching components on both sides of the punching device 3 start working. The drive device 214 pushes the needle plate 9 to move along the guide rod 24 towards the mushroom bag, and the punching needle 20 on the needle plate 9 passes through the bag. The hole 25 on the arc surface of the clamping block 12 contacts the mushroom bag, and the spring 10 between the punching needle 20 and the needle plate 9 is compressed to buffer the punching impact and prevent it from penetrating too deeply. After punching, the second drive device 14 drives the needle plate 9 to reset, and the spring 10 rebounds to make the punching needle 20 retract into the cavity of the clamping block 12. Then the first drive device 13 drives the clamping block 12 to release the mushroom bag. Finally, the punched mushroom bag falls into the conveying slide 15 of the sliding conveying mechanism 2. According to the height of the culture rack 18, the operator stretches the three-section conveying slide 15 to a suitable length through the slide groove 21 and the slider 23, and adjusts the tilt angle of the slide. The mushroom bag is conveyed along the slide by gravity. The baffle 16 at the end of the slide is located on the culture rack 18 to prevent the mushroom bag from falling. Finally, the mushroom bag is conveyed to the culture rack 18. If the device needs to be moved to another location, the brake assembly of the caster wheel can be released to steer and move flexibly; when storing, slide the third section of the conveyor slide 15 into the second section, and then slide the second section into the first section to shorten the length for easy handling and storage.
