Description

Technical Field

[0001] This utility model relates to the field of shiitake mushroom log monitoring technology, and in particular to a device for monitoring the growth status of shiitake mushroom logs. Background Technology

[0002] The mycelial growth, color change, mushroom bud germination, and contamination by other microorganisms during the cultivation of shiitake mushroom logs directly determine the final yield and quality of the finished product. Large-scale edible mushroom factories generally set up image detection processes to monitor the growth status of the logs in real time.

[0003] Currently, in the monitoring of shiitake mushroom spawn growth, the spawn is usually placed directly on a rack, and real-time image acquisition is carried out by monitoring equipment. Existing monitoring equipment generally adopts a fixed camera position structure, with a relatively fixed shooting angle and acquisition range. It can only acquire image data from a single direction of the shiitake mushroom spawn, and cannot cover the detection area around the spawn. This easily leads to the problem of incomplete image acquisition of shiitake mushrooms on the spawn, making it difficult to accurately monitor and judge the growth status of the shiitake mushroom spawn. In order to achieve all-round image acquisition of shiitake mushroom spawn and fully grasp its overall growth status, it is necessary to manually flip and adjust the angle of the spawn to achieve multi-angle image acquisition. This manual operation method is cumbersome and has a low degree of automation. It not only greatly increases the labor intensity, but also interrupts the continuous monitoring process, resulting in inconvenience to the monitoring operation. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a device for monitoring the growth status of shiitake mushroom spawn.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shiitake mushroom spawn growth status monitoring device, including a main frame, a support on the main frame, a detection device for monitoring shiitake mushroom spawn and a placement device for placing shiitake mushroom spawn on the main frame, the placement device including a placement component, the placement component including a frame fixedly connected to the main frame, a top plate disposed above the frame and a rotating frame rotatably connected to the top plate, the placement device also including an angle adjustment component for multi-angle adjustment of the top plate, a clamping component disposed on the rotating frame for clamping shiitake mushroom spawn, and a rotating component for controlling the rotation of the rotating frame.

[0006] By adopting the above technical solution, during operation, the clamping component secures and positions the shiitake mushroom logs, while the detection device acquires images of the logs to determine their growth status. During the image acquisition phase, the angle adjustment component allows for adjustment of the top plate's tilt angle, while the rotating component drives the rotating frame to synchronously rotate the clamped shiitake mushroom logs, flexibly changing their spatial orientation and enabling the detection device to acquire images from multiple angles. This solution eliminates the need for manual adjustment of the log positions, boasts a high degree of automation, and effectively improves the accuracy of identifying and judging the growth status of shiitake mushroom logs.

[0007] Furthermore, the angle adjustment component includes multiple electrically operated telescopic rods rotatably connected to the frame and a Hooke's hinge installed between the electrically operated telescopic rods and the top plate.

[0008] By adopting the above technical solution, when adjusting the attitude of the roof, each group of electric telescopic rods is driven to extend and retract synchronously or differently, and the multi-directional rotational freedom provided by the Hooke hinge is used to achieve multi-dimensional angle adjustment of the roof.

[0009] Furthermore, the clamping component includes two clamping seats that are slidably connected to the rotating frame, a bidirectional screw rod that is rotatably connected to the rotating frame and threadedly connected to the two clamping seats, a main conical rod fixed to the clamping seats, a limiting plate fixed to the main conical rod, and two auxiliary conical rods fixed to the limiting plate.

[0010] By adopting the above technical solution, when clamping the shiitake mushroom logs, rotating the bidirectional screw two causes the two clamping seats to move synchronously. The two clamping seats respectively drive the main conical rod to be inserted into the shiitake mushroom logs. The limiting plate can fit and limit the end face of the shiitake mushroom logs. Then, the secondary conical rod can be inserted into the shiitake mushroom logs to further improve the clamping stability.

[0011] Furthermore, the main conical rod is hollow, one end of the main conical rod is fixedly connected to a threaded joint, and the surface of the main conical rod is provided with multiple micro holes.

[0012] By adopting the above technical solution, the water supply pipe can be connected to the main conical rod through a threaded joint. The water supply pipe can then input water into the main conical rod and finally discharge it through the micro-holes to replenish the moisture of the shiitake mushroom logs.

[0013] Furthermore, the rotating component includes a gear ring fixedly sleeved on the rotating frame, a motor three mounted on the top plate, and a gear fixedly sleeved on the output end of the motor three and meshing with the gear ring.

[0014] By adopting the above technical solution, when the rotating frame is controlled to rotate, motor three is started. Motor three can drive the gear to rotate, and the gear, in conjunction with the gear ring, can drive the rotating frame to rotate, thereby adjusting the orientation of the shiitake mushroom sticks.

[0015] Furthermore, the detection device includes an adjustment bracket mounted on the support, a ring light mounted on the adjustment bracket, a depth camera mounted on the ring light, a control box mounted on the main frame, and a touch screen mounted on the main frame. The control box is electrically connected to the touch screen and the depth camera. The detection device also includes a supplementary lighting component for supplementing light to the shiitake mushroom logs.

[0016] By adopting the above technical solution, the shooting angle and height of the depth camera can be pre-adjusted during the detection process by adjusting the support. The support can adopt a conventional structure in this field, and its specific construction will not be described in detail here. The depth camera can acquire images of shiitake mushroom logs in real time. At the same time, the supplementary lighting component, together with the ring light, can eliminate hard shadows on the surface of the logs and weaken the contrast between light and dark in the image; it can fully illuminate the gaps and depressions around the logs, enriching the image texture features, effectively reducing the problems of missing depth values ​​and point cloud fragmentation during the acquisition process. The imaging data and depth acquisition data are complete and reliable, improving the accuracy of detecting the growth status of shiitake mushroom logs.

[0017] Furthermore, the supplementary lighting component includes two slides slidably connected to the main frame and symmetrically arranged about the middle of the main frame, a rotating ring rotatably connected to the slides, and supplementary lights mounted on the rotating ring. The supplementary lighting component also includes a control component one for controlling the movement of the slides and a control component two for controlling the rotation of the rotating ring.

[0018] By adopting the above technical solution, two supplementary lights and two slides are located on both sides of the shiitake mushroom log to supplement the light to promote the growth of the shiitake mushroom log. Control component one can control the movement of the two slides to adjust the distance between the supplementary lights and the shiitake mushroom log. Control component two can control the rotation of the rotating ring, which drives the supplementary lights to adjust the direction of the supplementary light.

[0019] Furthermore, the control component includes a bidirectional screw that is rotatably connected to the main frame and threadedly connected to the two carriages, a motor mounted on the main frame and whose output end is fixedly connected to one end of the bidirectional screw, and a support wheel disposed below the carriage.

[0020] By adopting the above technical solution, when controlling the carriage, start motor one, motor one drives double screw one to rotate, double screw one drives the two carriages to move along the main frame, and the support wheels can support and reinforce the carriages.

[0021] Furthermore, the second control component includes a second motor mounted on the slide, a worm gear rotatably connected to the slide and fixedly connected at one end to the output end of the second motor, and a worm wheel fixedly sleeved on the rotating ring and meshing with the worm gear.

[0022] By adopting the above technical solution, when controlling the rotating ring, motor two is started. Motor two can drive the worm to rotate, and the worm, together with the worm wheel, can drive the rotating ring to rotate, thereby adjusting the position of the supplementary light.

Together with the detection device, it can complete the acquisition of multi-directional images of the mushroom sticks, eliminate blind spots in the shooting, eliminate the need for manual movement and flipping of the mushroom sticks, achieve a high level of automation, and improve the accuracy of identifying the growth status of shiitake mushroom sticks.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-7 As shown in the illustration, this application discloses a device for monitoring the growth status of shiitake mushroom spawn, including a main frame 1, a support 2, a detection device 3, and a placement device 4. The support 2 is mounted on the main frame 1, and the placement device 4 is mounted on the main frame 1 for placing shiitake mushroom spawn. The placement device 4 includes a placement component 41, an angle adjustment component 42, a clamping component 43, and a rotating component 44. The placement component 41 includes a frame 411, a top plate 412, and a rotating frame 413. The frame 411 is fixedly connected to the main frame 1. The top plate 412 is positioned above the frame 411, and the rotating frame 413 is rotatably connected to the top plate 412. During operation, the clamping component 43 clamps and positions the shiitake mushroom logs, while the detection device 3 acquires images of the logs to determine their growth status. During image acquisition, the tilt angle of the top plate 412 can be adjusted using the angle adjustment component 42, while the rotating component 44 drives the rotating frame 413 to rotate the clamped shiitake mushroom logs synchronously, flexibly changing their spatial orientation and enabling the detection device 3 to acquire images from multiple angles. This solution eliminates the need for manual adjustment of the log positions, boasts a high degree of automation, and effectively improves the accuracy of identifying and judging the growth status of the shiitake mushroom logs.

[0028] An angle adjustment component 42 is used for multi-angle adjustment of the top plate 412. The angle adjustment component 42 includes an electric telescopic rod 421 and a Hooke hinge 422. Multiple electric telescopic rods 421 are provided and rotatably connected to the frame 411. The Hooke hinge 422 is installed between the electric telescopic rods 421 and the top plate 412.

Utilizing the multi-directional rotational freedom provided by the Hooke hinge 422, multi-dimensional angle adjustment of the top plate 412 is achieved.

[0029] A clamping component 43 is mounted on a rotating frame 413 and is used to clamp mushroom spawn. The clamping component 43 includes a clamping seat 431, a bidirectional screw 432, a main conical rod 433, a limiting plate 434, and a secondary conical rod 435. Two clamping seats 431 are provided, and the two clamping seats 431 are slidably connected to the rotating frame 413. The bidirectional screw 432 is rotatably connected to the rotating frame 413 and threadedly connected to the two clamping seats 431. The main conical rod 433 is fixed to the clamping seat 431. The limiting plate 434 is fixed to the main conical rod 433. Two secondary conical rods 435 are provided, and the two secondary conical rods 435 are fixed to the limiting plate 434. When clamping the shiitake mushroom logs, rotate the double-headed screw 432. The double-headed screw 432 drives the two clamping seats 431 to move synchronously. The two clamping seats 431 respectively drive the main conical rod 433 to insert into the shiitake mushroom logs. The limiting plate 434 can fit and limit the end face of the shiitake mushroom logs. Then, the secondary conical rod 435 can be inserted into the shiitake mushroom logs to further improve the clamping stability.

[0030] The main conical rod 433 is hollow, and a threaded connector 5 is fixedly connected to one end of the main conical rod 433. Multiple micro holes 6 are opened on the surface of the main conical rod 433. It can be connected to a water supply pipe through the threaded connector 5. The water supply pipe can input water into the main conical rod 433 and finally discharge it through the micro holes 6 to replenish the moisture of the shiitake mushroom sticks.

[0031] The rotating component 44 is used to control the rotation of the rotating frame 413. The rotating component 44 includes a gear ring 441, a motor 442, and a gear 443. The gear ring 441 is fixedly sleeved on the rotating frame 413, the motor 442 is mounted on the top plate 412, and the gear 443 is fixedly sleeved on the output end of the motor 442 and meshes with the gear ring 441. When controlling the rotation of the rotating frame 413, the motor 442 is started, which drives the gear 443 to rotate. The gear 443, in conjunction with the gear ring 441, drives the rotating frame 413 to rotate, adjusting the orientation of the shiitake mushroom logs.

[0032] The detection device 3 is mounted on the main frame 1 and is used to monitor the shiitake mushroom logs. The detection device 3 includes an adjustable bracket 31, a ring light 32, a depth camera 33, a control box 34, a touch screen display 35, and supplementary lighting components. The adjustable bracket 31 is mounted on the support 2, and the ring light 32 is mounted on the adjustable bracket 31. The depth camera 33 is mounted on the ring light 32, and the control box 34 is mounted on the main frame 1. The touch screen display 35 is mounted on the main frame 1, and the control box 34 is electrically connected to the touch screen display 35 and the depth camera 33. During the detection process, the shooting angle and height of the depth camera 33 can be pre-adjusted by adjusting the bracket 31 to maintain a collection distance of approximately 40cm between the depth camera 33 (RealSense D435i) and the surface of the mushroom log. The adjustment bracket 31 can adopt a conventional structure in the field, and its specific construction will not be described in detail here. The depth camera 33 can acquire images of the shiitake mushroom log in real time, and turn on the ring light 32 and the two-sided supplementary lights 38 to obtain relatively stable and uniform lighting conditions on the surface of the mushroom log. This can eliminate hard shadows on the surface of the mushroom log and weaken the contrast between light and dark in the image; it can fully illuminate the gaps and depressions around the mushroom log, enrich the image texture features, and effectively reduce the problems of missing depth values ​​and point cloud fragmentation during the acquisition process. The imaging data and depth acquisition data are complete and reliable, improving the accuracy of the detection of the growth status of the shiitake mushroom log. After the device is started, the operator clicks the "Start" button on the touch screen 35. The system then calls the depth camera 33 to acquire the RGB image and depth map of the current mushroom stick area. After acquisition, the device transmits the image data and camera parameters to the backend server, which performs the segmentation of the mushroom cap and stem, the completion of the occluded area, and the subsequent calculation of phenotypic parameters. During the calculation, the system constrains the effective depth area based on the complete mask and combines the camera intrinsic parameters to complete the point cloud reconstruction and parameter extraction. After the backend server completes the calculation, it returns the measurement results to the device's touch screen 35. The interface mainly displays four phenotypic parameters: cap diameter, cap height, stem length, and stem thickness. If multiple mushroom individuals are identified in an image, the system can display the corresponding measurement results sequentially according to the individual number. The detection results are also saved as a local CSV file for easy comparison and analysis with manual measurement data. The overall operation process realizes a closed loop from RGB-D image acquisition, model analysis, parameter calculation to result display and saving.
