Description

Technical Field

[0001] This utility model relates to the field of white jade mushroom inoculation technology, and in particular to a perforation device for white jade mushroom inoculation bottles. Background Technology

[0002] White jade mushrooms are a rare and highly sought-after edible fungus variety in industrialized bottle cultivation. Inoculation is a crucial step determining its yield and quality. Before inoculation, a perforating device is needed to create holes of a specific depth in the culture medium inside the cultivation bottle, allowing liquid or solid spawn to enter the medium. Existing perforation devices for white jade mushroom inoculation bottles typically include a frame, a mounting frame, and multiple perforating rods arranged in a square array on the mounting frame. A sleeve is fitted around the perforating rod; during operation, the bottom end of the sleeve presses against the edge of the bottle mouth to position the cultivation bottle, while the perforating rods are inserted downwards into the culture medium to complete the perforation.

[0003] However, existing punching devices generally suffer from the following problems in use: After long-term reciprocating motion, gaps develop between the punching rod shaft and the inner wall of the cup, causing radial movement of the punching rod shaft. This scrapes against the inner wall of the bottle opening during insertion and withdrawal, producing burrs. These burrs not only affect the appearance of the bottle opening but also easily trap bacteria, increasing the risk of contamination. Simultaneously, each cup is independently installed on the mounting frame, lacking a unified height positioning benchmark. This results in inconsistent insertion depths of the punching rod shafts and varying material surface depths in each bottle (differences can reach 0.3–1.2 cm), directly causing uneven inoculation amounts and affecting synchronous mycelial growth and yield stability. Furthermore, the bottom surface of the cup rubs against the bottle opening and is subjected to scouring by culture medium particles over a long period. Ordinary material cups show significant wear after only a few months of use, exhibiting poor precision retention and recurring burr problems. Frequent cup replacements also increase maintenance costs and production downtime. Utility Model Content

[0004] In view of this, this utility model provides a punching device for white jade mushroom inoculation bottles, which solves the problems of existing punching devices, such as radial movement of the punching rod shaft, inconsistent height of multi-station cups, and easy wear, which lead to burrs at the bottle mouth, inconsistent material depth, and thus uneven inoculation amount and increased risk of contamination.

[0010] Preferably, the radial locking element is a round-headed set screw, and the side wall of the sleeve is provided with a threaded hole that matches the round-headed set screw.

[0014] The punching device for the white jade mushroom inoculation bottle provided by this utility model has the following beneficial effects: This invention utilizes a first drive unit to drive the moving frame along a guide rod for rapid, large-stroke lifting and positioning. A second drive unit independently drives the inoculation plate along the lifting guide rod for precise, small-stroke drilling. This hierarchical approach to coarse and fine positioning reduces the design complexity of a single drive mechanism, minimizes the inertia and impact of moving parts, and improves the long-term repeatability and stability of the drilling rod shaft. Furthermore, it allows the moving frame to be pre-raised to facilitate smooth entry and exit of the conveyor mechanism, significantly increasing overall machine efficiency. Simultaneously, the drilling positioning components on each drilling rod shaft ensure reliable positioning of the cultivation bottle by first pressing the bottle mouth against the perforated container during drilling. The radial locking mechanism effectively eliminates radial movement of the drilling rod shaft, preventing it from scraping the inner wall of the bottle mouth and creating burrs, thus reducing the risk of bacterial contamination. The wear-resistant components significantly extend the service life and accuracy maintenance period of the perforated container. This comprehensive approach achieves efficient, precise, stable, and low-pollution inoculation and drilling operations for white jade mushroom bottles. Attached Figure Description

[0018] Please see Figures 1-4 This utility model provides a punching device for inoculation bottles of white jade mushrooms, characterized in that it includes a frame 110, an inoculation mechanism, a conveying mechanism, a driving mechanism, and a punching and positioning assembly; the frame 110 has a frame-shaped structure and is arranged around the perimeter, and a pair of guide rods 115 are respectively arranged on both sides of the frame 110, and a movable frame is provided through the guide rods 115; the conveying mechanism 130 is arranged inside the frame 110 for conveying the inoculation frame; the inoculation mechanism includes an inoculation plate 210 and a plurality of punching rod shafts 220 arranged in a square array on the inoculation plate 210, and the inoculation mechanism is driven by... A number of lifting guide rods 230 are disposed on the movable frame; the driving mechanism includes a first driving part and a second driving part, the first driving part is used to drive the movable frame to move up and down along the guide rod 115; the second driving part is disposed on the movable frame and is used to drive the inoculation mechanism to move up and down along the lifting guide rod 230, so as to drive the punching rod shaft 220 to perform inoculation punching operation; the punching positioning component is correspondingly disposed on each punching rod shaft 220, and is used to make the punching rod shaft 220 vertically inserted without shaking and press the bottle mouth, and to make the punching depth and material surface height of all inoculation bottles consistent.

[0019] In this embodiment, the perforation device for the white jade mushroom inoculation bottles is supported by a frame 110. The frame 110 has a frame-like structure arranged around the equipment, and a conveying mechanism 130 is installed inside to transport the inoculation frame carrying several cultivation bottles to the perforation station. A pair of guide rods 115 are vertically arranged on both sides of the frame 110, and a movable frame is slidably mounted on the guide rods 115 through guide sleeves 114. During operation, the conveying mechanism 130 transports the inoculation frame to a predetermined position directly below the perforation rod shaft 220 and then pauses. Subsequently, the drive mechanism actuates, causing the inoculation plate 210 and the perforation rod shaft 220 to move downwards, completing the perforation operation of the culture medium in the cultivation bottles.

[0020] The drive mechanism employs a two-stage lifting drive. The first drive unit is located at the top of the frame 110 and drives the entire moving frame to move up and down along the guide rod 115, enabling rapid lifting and lowering of the punching device over a large stroke. The second drive unit is located on the moving frame and drives the inoculation mechanism to move up and down independently along the lifting guide rod 230, thereby driving the punching rod shaft 220 to perform the inoculation punching operation. Through the coordinated operation of the two-stage drive mechanism, the work efficiency can be improved while ensuring the accuracy of the punching stroke. The inoculation plate 210 is mounted on the moving frame via several lifting guide rods 230, and the punching rod shafts 220 are arranged in a square array on the inoculation plate 210, with the position of each punching rod shaft 220 corresponding one-to-one with the position of the bottle mouth of each cultivation bottle in the inoculation frame.

[0021] Each perforating rod shaft 220 is equipped with a corresponding perforation positioning component. When the perforating rod shaft 220 descends with the inoculation plate 210 and is inserted into the culture medium, the perforation positioning component first contacts and presses against the bottle mouth, reliably positioning the culture bottle; then the perforating rod shaft 220 continues to extend downwards, vertically and without wobbling into the culture medium to the set depth under the guidance and constraint of the perforation positioning component. Since the installation height of each perforation positioning component is uniformly calibrated, the insertion depth of all perforating rod shafts 220 is consistent, thereby ensuring that the material surface height and perforation depth of each culture bottle remain uniform, effectively guaranteeing the uniformity of subsequent inoculation volume, while avoiding the formation of rough edges due to the perforating rod shaft 220 wobbling and scraping the inner wall of the bottle mouth, reducing the risk of contamination by other microorganisms.

[0022] Furthermore, the frame 110 includes two pairs of fixed end plates 111 disposed on the top and bottom of both sides, and the guide rod 115 is disposed between the fixed end plates 111; the guide rod 115 is also provided with a fixed plate 112, and the fixed plate 112 is provided with a bearing 113.

[0023] The first drive unit is provided with a first commutator 211 and a second commutator 212 on the top of the frame 110. The first commutator 211 and the second commutator 212 are connected by a drive shaft 213. The first commutator 211 is driven by a drive motor 214. The first commutator 211 and the second commutator 212 are respectively provided with a first lead screw 215 and a second lead screw 216. The movable frame includes a floating plate 121 disposed on the guide rod 115 via a guide sleeve 114, and the first lead screw 215 and the second lead screw 216 are fixedly connected to the bearing 113; the floating plate 121 is provided with a threaded sleeve 122 that is threadedly connected to the first lead screw 215 and the second lead screw 216; the movable frame also includes a receiving plate 123, which is disposed on the guide rod 115 via the guide sleeve 114, and the receiving plate 123 is connected to the floating plate 121 via a connecting rod.

[0024] In this embodiment, the frame 110 serves as the supporting foundation for the entire device. Two pairs of fixed end plates 111 are fixedly installed at the top and bottom of both sides of the frame 110. A guide rod 115 is vertically installed between the upper and lower fixed end plates 111 on the same side, forming a stable guide support structure. A fixed plate 112 is also fixedly installed on the guide rod 115, and a bearing 113 is installed on the fixed plate 112 to provide rotational support for the lead screw. The first drive unit adopts a dual-lead screw synchronous drive method, including a first commutator 211 located on one side of the top of the frame 110 and a second commutator 212 located on the other side. The first commutator 211 and the second commutator 212 are connected by a transmission shaft 213. The first commutator 211 is driven by a drive motor 214, which synchronously transmits power to both sides through the first commutator 211, the transmission shaft 213, and the second commutator 212. The first commutator 211 and the second commutator 212 are respectively connected to the first lead screw 215 and the second lead screw 216 extending vertically downward. The lower ends of the two lead screws are respectively fixedly connected to the bearings 113 on the fixed plate 112 to ensure the concentricity and stability of the lead screws when rotating.

[0025] The mobile frame adopts a double-layer structure, including a floating plate 121 and a receiving plate 123. The floating plate 121 is slidably mounted on the guide rod 115 via a guide sleeve 114. A threaded sleeve 122 is fixedly installed on the floating plate 121, which forms a threaded engagement with the first lead screw 215 and the second lead screw 216 respectively. When the drive motor 214 of the first drive unit operates, the two lead screws rotate synchronously, driving the floating plate 121 to rise and fall smoothly along the guide rod 115 via the threaded sleeve 122. The receiving plate 123 is also slidably mounted on the guide rod 115 via the guide sleeve 114 and is located below the floating plate 121. The receiving plate 123 is fixedly connected to the floating plate 121 via several connecting rods, so that the receiving plate 123 rises and falls synchronously with the floating plate 121. The receiving plate 123 is used to support the second drive unit and the inoculation mechanism. This double-layer mobile frame design not only ensures the smoothness and guiding accuracy of the lifting movement, but also provides sufficient installation space for the drive mechanism, realizing the separation of large-stroke lifting and precise drilling action, and further improving the stability and reliability of the drilling operation.

[0026] Furthermore, the second driving unit includes an electric cylinder 221 disposed on the receiving plate 123 and a pair of push rods 223 disposed on the inoculation plate 210. The top of the pair of push rods 223 is provided with a driving plate 224, and the push rod 222 of the electric cylinder 221 is connected to the driving plate 224. The inoculation plate 210 is connected to a plurality of lifting guide rods 230 disposed on the receiving plate 123 through a guide sleeve 114.

[0027] In this embodiment, the second drive unit is used to drive the inoculation mechanism to perform independent drilling and lifting actions along the lifting guide rods 230. The second drive unit includes an electric cylinder 221 fixedly mounted on the receiving plate 123. A pair of push rods 223 are vertically mounted on the inoculation plate 210. The tops of the two push rods 223 are connected to a driving plate 224. The push rod 222 of the electric cylinder 221 extends upward and is fixedly connected to the driving plate 224. The inoculation plate 210 is slidably mounted on a plurality of vertically mounted lifting guide rods 230 on the receiving plate 123 via a guide sleeve 114. During operation, the push rod 222 of the electric cylinder 221 extends upward, pushing the drive plate 224 to rise. The drive plate 224, through two push rods 223, pulls the inoculation plate 210 upward along the lifting guide rod 230, causing the perforating rod shaft 220 to retract from the culture medium, completing the return action. When the push rod 222 of the electric cylinder 221 retracts downward, the drive plate 224 descends, and the push rods 223 push the inoculation plate 210 downward along the lifting guide rod 230, causing the perforating rod shaft 220 to insert into the culture medium to perform the perforation operation. Through precise push stroke control of the electric cylinder 221, the insertion depth of the perforating rod shaft 220 can be precisely adjusted to ensure consistent perforation depth each time. The second drive unit is independently set on the moving frame, separate from the first drive unit (which drives the overall lifting and lowering of the moving frame), so that the large-stroke lifting and positioning of the moving frame and the precise perforation action of the inoculation plate 210 do not interfere with each other, which improves perforation efficiency and ensures the control accuracy of perforation depth.

[0028] In this invention, the first drive unit drives the entire moving frame to move up and down along the guide rod 115 with a large stroke, enabling the inoculation mechanism to quickly approach the mouth of the cultivation bottle for coarse positioning. The second drive unit independently drives the inoculation plate 210 to move up and down precisely along the lifting guide rod 230 with a small stroke, performing the insertion and extraction of the punching rod shaft 220 for fine positioning. Through this dual-drive, graded action design, on the one hand, the large-stroke rapid feed and the small-stroke precise punching are separated, avoiding the structural complexity and control difficulty caused by a single drive mechanism having to simultaneously handle large stroke and high precision, thus improving the consistency and control accuracy of the punching depth. On the other hand, the movements of the moving frame and the inoculation plate 210 do not interfere with each other. The moving frame can be pre-raised to a high position to facilitate the smooth entry and exit of the conveying mechanism 130, while the inoculation plate 210 only performs precise reciprocating motion based on the positioning of the moving frame during punching, reducing the inertia and impact of moving parts, effectively ensuring the long-term position repeatability and stability of the punching rod shaft 220, and improving the overall operating efficiency and reliability of the machine.

[0029] Furthermore, the drilling and positioning assembly includes a sleeve 410, a reinforcing connection structure, a radial locking element, and a wear-resistant component; The sleeve 410 is fixedly installed on the punching rod shaft 220, and the punching rod shaft 220 is axially movably inserted into the center hole of the sleeve 410. The sleeve 410 is used to press the bottle mouth during punching. The reinforcing connection structure is provided at the connection between the sleeve cup 410 and the punch rod shaft 220 to increase the connection rigidity between the sleeve cup 410 and the punch rod shaft 220. The radial locking member is disposed on the side wall of the sleeve cup 410 and extends radially. The inner end of the radial locking member abuts against the outer peripheral surface of the punching rod shaft 220 to restrict the radial movement of the punching rod shaft 220. The wear-resistant component is disposed on the outer surface of the sleeve cup 410, and the lower end face of the wear-resistant component does not protrude from the bottom end face of the sleeve cup 410, in order to reduce the wear of the bottom end face of the sleeve cup 410.

[0030] Furthermore, the side wall of the sleeve 410 is provided with a threaded hole that matches the round head set screw 430. After the round head set screw 430 passes through the threaded hole, its end abuts against the outer wall of the punching rod shaft 220.

[0031] Furthermore, the reinforcing connection structure is a thickened weld layer deposited at the corner where the outer wall of the sleeve cup 410 connects to the lower surface of the punching rod shaft 220.

[0032] Furthermore, the wear-resistant strip 420 is made of cemented carbide or wear-resistant steel.

[0033] Furthermore, the wear-resistant component is a wear-resistant strip 420 embedded on the outer surface of the sleeve 410 or on the outer peripheral wall adjacent to the bottom end face. The wear-resistant strips 420 are distributed at intervals along the circumference of the sleeve 410, and the bottom end face of the wear-resistant strip 420 is flush with or above the bottom end face of the sleeve 410.

[0034] In this embodiment, the drilling and positioning assembly specifically includes a sleeve 410, a reinforcing connection structure, a radial locking component, and a wear-resistant component. The sleeve 410 is fixedly installed on the drilling rod shaft 220, which axially moves through the central hole of the sleeve 410 and is fixed therein. During drilling, the bottom end face of the sleeve 410 directly presses against the edge of the cultivation bottle's mouth, providing a clamping and positioning effect. The reinforcing connection structure is located at the corner where the outer wall of the sleeve 410 connects to the lower surface of the drilling rod shaft 220. Specifically, it is a thickened weld layer formed by welding at this corner. By increasing the weld height and contact area, the connection rigidity between the sleeve 410 and the drilling rod shaft 220 is significantly improved, effectively preventing the sleeve 410 from loosening or shifting under long-term reciprocating stress. A radial locking member is disposed on the side wall of the sleeve cup 410 and extends radially, with its inner end abutting against the outer circumferential surface of the punching rod shaft 220 to limit the radial movement of the punching rod shaft 220. In a preferred embodiment, a threaded hole is provided on the side wall of the sleeve cup 410, and the radial locking member is a round-headed set screw 430. After the round-headed set screw 430 passes through the threaded hole, its end abuts against the outer wall of the punching rod shaft 220. The round-headed design can prevent the screw tail from scratching the operator or surrounding parts. At the same time, the end of the set screw 430 forms a stable pressing fit with the outer wall of the punching rod shaft 220, eliminating the radial gap between the punching rod shaft 220 and the inner wall of the sleeve cup 410, so that the punching rod shaft 220 always remains vertical during the lifting and lowering process, and fundamentally avoiding the generation of burrs caused by shaking and scratching the inner wall of the bottle mouth. Wear-resistant components are provided on the outer surface of the cup 410 to reduce wear on the bottom end face of the cup 410 during long-term friction with the bottle mouth and scouring by culture medium particles.

[0035] In a preferred embodiment, the wear-resistant component is a wear-resistant strip 420 embedded in the outer surface of the sleeve 410 or on the outer peripheral wall adjacent to the bottom end face. The wear-resistant strip 420 is distributed circumferentially along the sleeve 410 and is made of hard alloy or wear-resistant steel, possessing hardness and wear resistance far exceeding that of ordinary steel. The bottom end face of the wear-resistant strip 420 is flush with or slightly above the bottom end face of the sleeve 410, meaning the lower end face of the wear-resistant component does not protrude from the bottom end face of the sleeve 410. This effectively protects the end face of the sleeve 410 from wear and prevents scratching of the culture medium surface and bottle mouth due to excessive length of the wear-resistant strip 420, ensuring drilling quality while significantly extending the service life of the sleeve 410. Through the combination of the aforementioned cup 410, reinforcing welds, radial locking screws, and bottom wear-resistant strip 420, the drilling positioning assembly achieves precise guidance of the drilling rod shaft 220, reliable clamping of the bottle mouth, and wear-resistant reinforcement of its own vulnerable parts, thereby ensuring the consistency of drilling depth and the stability of bottle mouth quality during long-term use.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
