Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicinal material planting, and in particular to a Chinese medicinal material nursery bed with air permeability detection capability. Background Art

[0002] At present, the seedling cultivation of Chinese medicinal materials is centralized, which can realize large-scale production, improve the supply efficiency of seedlings, and meet the needs of large-scale planting. And the seedling beds needed in the seedling cultivation process, using trays to cultivate the seedlings of Chinese medicinal materials, can improve land utilization. Among them, the seedling cultivation requirements of Chinese medicinal materials require fertile, loose, and well-drained soil as the seedling matrix. However, during the seedling cultivation process, excessive fertilization or excessive watering may occur, resulting in the inability to keep the soil for seedling cultivation loose, which in turn causes the soil to be too compact, making the soil permeability poor, and ultimately causing the roots of Chinese medicinal materials seedlings to be damaged, reducing the finished product rate of Chinese medicinal materials seedling cultivation.

[0003] The existing method requires direct observation by human eyes to check the compactness of the soil one by one, and tools such as thin wooden sticks or small shovels can be used to gently insert them into the soil of the nursery bed. If it can be inserted relatively easily and there is no obvious resistance during the insertion and removal process, it means that the soil has good air permeability. Both methods cannot quickly check the air permeability of the soil, and the efficiency is low and the labor cost is high. However, the existing method requires manual use of tools such as small shovels to loosen multiple rows of soil one by one. The manual soil insertion detection and loosening method not only increases labor costs, but also inevitably causes soil to spill in the process of manually shoveling the soil loose. Not only does it need to be cleaned, but after falling, it will cause the soil that the Chinese medicinal material seedlings have adapted to be wasted, and the soil needs to be replenished or fertilized and watered again, which affects the growth of the Chinese medicinal material seedlings.

[0043] like Figures 5 to 8As shown, the servo motor 56 is provided with a detection component for detecting soil compaction, and the detection component includes a connecting plate 61 fixedly connected to the side of the servo motor 56 away from the cam plate 57 by bolts, and a lifting groove 62 is provided on the connecting plate 61, and two springs 63 are fixedly connected to the bottom of the lifting groove 62, and the tops of the two springs 63 are fixedly connected to a lifting block 64, and the lifting block 64 slides inside the lifting groove 62, and the outer surface of the lifting block 64 is fixedly connected to an inclined plate 65, and the inclined plate 65 is fixedly connected to a detection rod 66, a compression chamber 67 is provided at one end of the detection rod 66 away from the inclined plate 65, a spring 68 is fixedly connected to the top of the compression chamber 67, a detection head 69 is fixedly connected to the bottom end of the spring 68, the top end of the detection head 69 slides inside the compression chamber 67, a groove is provided on the detection rod 66 for the detection head 69 to pass through, an extrusion ring 610 is fixedly connected to the outer surface of the detection head 69 passing through the groove, the extrusion ring 610 slides on the outer surface of the detection rod 66, and a pressure switch 611 is symmetrically fixedly connected to the outer surface of the detection rod 66.

[0044] like Figure 5 and Figure 8 As shown, a cleaning component for scraping soil off the outer surface of the detection head 69 is provided at the bottom of the connecting plate 61. The cleaning component includes a connecting frame 71 fixedly connected to the bottom of the connecting plate 61. A cleaning ring 72 is fixedly connected to the bottom end of the connecting frame 71. The cleaning ring 72 is sleeved on the outer surface of the detection head 69.

[0045] like Figure 5 , Figure 6 , Figures 9 to 11 As shown, a pressing assembly for pushing the detection assembly down is provided on the connecting plate 61, and the pressing assembly includes a fixing frame 81 fixedly connected to the top of the connecting plate 61, the interior of the fixing frame 81 is a cavity structure, and a plurality of stable grooves 82 are symmetrically provided on the outer surface of the fixing frame 81, and a gear 83 is rotatably connected to the interior of the fixing frame 81, and a gear rod 84 is slidably connected in one of the stable grooves 82, and the gear rod 84 and the gear 83 are meshed with each other, and a resistance rod 85 is fixedly connected to a side of the gear rod 84 away from the fixing frame 81, and a resistance wheel 86 is rotatably connected to the end of the resistance rod 85 away from the gear rod 84, and the resistance wheel 86 is fitted with the outer surface of the cam plate 57, and a gear rod 2 87 is slidably connected to the stable groove 82 away from the side of the gear rod 1 84, and the gear rod 2 87 is meshed with the gear 83, and the bottom of the gear rod 2 87 is in conflict with the upper surface of the lifting block 64, and the top of the fixing frame 81 is fixedly connected to the alarm device 9.

[0046] The following is the entire working process and working principle of the above embodiment:

[0047] The initial state is:

[0048] The gear rod 1 84 is at the lowest position of the stable groove 82 , the gear rod 2 87 is at the highest position, the spring 1 63 is not compressed by the lifting block 64 , and the lifting block 64 is at the highest position inside the lifting groove 62 .

[0049] The working status is:

[0050] The seedling tray 4 is placed on the seedling net 24, and the bottom of the seedling tray 4 is embedded between the three placement racks 33 of each group. The placement racks 33 can keep the position of the seedling tray 4 neat, and can facilitate the subsequent detection head 69 to be smoothly inserted into the soil in each grid of the seedling tray 4, ensuring that the subsequent detection component can effectively detect the compactness of the soil in each grid of the seedling tray 4, and the placement racks 33 can play a positioning role for the seedling tray 4 to prevent the seedling tray 4 from displacement on the seedling net 24.

[0051] When it is necessary to adjust the horizontal position of the seedling bed 2, the staff can turn the handle 23 on either side. When the handle 23 is turned, it will drive the movable rotating rod 22 to fit with the upper surface of the seedling frame 1, forming a friction movement similar to that between the rotating wheel and the guide rail, that is, the movable rotating rod 22 can rotate and synchronously drive the seedling bed 2 to slide on the seedling frame 1. Since a sliding frame 21 is provided, the movable rotating rod 22 can rotate on the sliding frame 21 and drive the sliding frame 21 to move horizontally synchronously, so as to limit the movable rotating rod 22 from detaching from the seedling frame 1, thereby realizing the adjustment of the horizontal position of the seedling bed 2. Usually, there are multiple groups of seedling frames 1 and seedling beds 2 in the room. By adjusting the horizontal position of each seedling bed 2, two seedling beds 2 close to each other can be brought closer to each other to expand the planting area, or two seedling beds 2 can be moved away from each other for staff to pass through, thereby improving the utilization rate of the seedling bed 2.

[0052] The moving component drives the detection component to move:

[0053] The servo motor 56 is started by an external controller, and the output shaft of the servo motor 56 drives the cam plate 57 to rotate clockwise. Figure 3 As shown in the clockwise direction, the cam plate 57 rotates clockwise, which drives the positioning ring 58 and the moving rod 59 to rotate synchronously, wherein the moving rod 59 slides in the moving groove 53, giving the cam plate 57 a thrust to move it to the right, that is, Figure 3On the right side shown in the figure, the cam plate 57 drives the servo motor 56 to move to the right inside the slide groove 55. During the sliding process of the servo motor 56, the fixing ring 510 keeps it stable under the sliding guide action of the guide frame 511, so that the servo motor 56 can stably slide inside the slide groove 55 without slipping, and the servo motor 56 is controlled by an external controller, so that the rotation speed of the servo motor 56 is uniform and slow. The movement of the servo motor 56 makes the detection component move synchronously. At the same time, the continued rotation of the cam plate 57 makes the moving rod 59 rotate upward and not fit the moving groove 53. At this time The cam plate 57 drives the positioning ring 58 to fit with the positioning groove 54. The fit between the positioning ring 58 and the positioning groove 54 can ensure that the cam plate 57 remains stable. At this time, the servo motor 56 drives the detection component to move and then remain stationary, and at this time the detection component will correspond to the position of one row of seedling trays 4. The above-mentioned cam plate 57 will cause the servo motor 56 to move horizontally intermittently during the continuous rotation process, so that the intermittent movement of the detection component can realize the soil compaction detection of different rows of seedling trays 4 in turn, reducing the steps of manually holding the soil compaction detection device for detection one by one, thereby improving the detection efficiency.

[0054] The pressing component enables the detection component to detect the soil:

[0055] During the rotation of the cam plate 57, when the positioning ring 58 is fitted with the positioning groove 54, the raised portion of the cam plate 57 faces upward, and the raised portion of the cam plate 57 pushes the contact wheel 86 that is fitted therewith, so that the contact wheel 86 moves upward, and the contact wheel 86 drives the contact rod 85 to move upward, and the contact rod 85 drives the gear rod 84 to move upward inside the stable groove 82, as shown in FIG. Fig.11As shown, when the gear rod 1 84 moves upward, it will drive the gear 83 to rotate counterclockwise inside the fixed frame 81, and the counterclockwise rotation of the gear 83 will drive the gear rod 2 87 to move downward in the stable groove 82. The downward movement of the gear rod 2 87 will push the lifting block 64 to move downward in the lifting groove 62, and the downward movement of the lifting block 64 will compress the spring 1 63. In addition, the downward movement of the lifting block 64 will drive the detection rod 66 to move downward synchronously through the inclined plate 65. The downward movement of the detection rod 66 will drive the detection head 69 sliding in the compression chamber 67 to move downward synchronously. The detection head 69 passes through the cleaning ring 72 and then moves downward. The detection head 69 will be inserted into the soil in the seedling tray 4. After the detection head 69 is resisted by the soil of different compactness in the seedling tray 4, if the soil in the seedling tray 4 is relatively loose, the detection head 69 can be smoothly inserted into the soil, and it is determined that the soil in the seedling tray 4 is air permeable. If the soil in the seedling tray 4 is relatively compact, the detection head 69 cannot be smoothly inserted into the soil, so that the detection head 69 will slide in the compression chamber 67 and compress the compression chamber 67. The sliding of the detection head 69 causes the extrusion ring 610 to slide on the outer surface of the detection rod 66. When the detection head 69 is inserted into the soil, the detection head 69 is subjected to different resistances from soils with different air permeabilities. The soil with poor air permeability is relatively dry and hard, and thus has a higher supporting force on the detection head 69, that is, the detection head 69 cannot be smoothly inserted into the soil. The soil with good air permeability is relatively moist and loose, and the detection head 69 cannot be smoothly inserted into the soil. The support force on the detection head 69 is relatively small, that is, the detection head 69 can be smoothly inserted into the soil. When the detection head 69 is inserted into the soil, the support force of the soil is relatively high, and the detection head 69 cannot move downward. When the detection rod 66 continues to move downward, the detection rod 66 will drive the pressure switch 611 on its outer side to move downward, and the pressure switch 611 will be squeezed by the squeezing ring 610. When the pressure switch 611 is squeezed, the alarm device 9 will be powered on through the controller, and the alarm device 9 will emit a warning sound after being powered on, judging that the soil in the seedling tray 4 is not air permeable. Through the reminder of the alarm device 9, it is possible to directly understand whether the soil is too compact and thus airtight, thereby reducing the need for manual inspection one by one, achieving the effect of automatically detecting the air permeability of the soil, and improving the efficiency of the soil air permeability detection.

[0056] By cooperating with the moving component, the detection of different rows of seedling trays 4 can be realized, so that the problem of airtight soil in the seedling trays 4 can be discovered in time. By detecting and understanding the difference in air permeability of the soil in different rows of seedling trays 4, the entire seedling area can be uniformly managed and adjusted. Moreover, by making the force consistency of the detection head 69 when inserting the soil each time, the soil detection standards of different rows of seedling trays 4 can be unified, thus avoiding detection deviation caused by different forces when manually inserting the soil.

[0057] The vibration component vibrates and loosens the soil in the seedling tray 4:

[0058] After the pressure switch 611 is squeezed, the controller will also start the vibrator 31 at the same time. After the vibrator 31 is started, it generates a vibration force, which is transmitted to the placement rack 33 through the vibration rod 32. The seedling tray 4 can be vibrated synchronously through the vibration of the placement rack 33, so that the compacted soil in the seedling tray 4 is vibrated and loosened, reducing the need to manually loosen the soil one by one, and improving the efficiency of loosening the soil in the seedling tray 4. In addition, loosening the soil by vibration can also avoid the existing manual loosening of the soil causing the soil to leak out of the seedling tray 4, reducing the need for additional steps to clean the soil and avoiding waste.

[0059] In addition, the vibrator 31 can be started manually, and the vibrator 31 can transmit the vibration force to the placement rack 33 through the vibration rod 32, and the soil in all seedling trays 4 can be vibrated to loosen, which is convenient for subsequent regular loosening maintenance of the soil.

[0060] The cleaning component removes the soil on the surface of the detection head 69:

[0061] When the non-convex part of the cam plate 57 rotates to fit with the abutment wheel 86, the cam plate 57 no longer pushes the abutment wheel 86, and the elastic extension of the spring 1 63 can push the lifting block 64 to move upward inside the lifting slot 62. When the lifting block 64 moves upward, it will push the gear rod 2 87 to move upward, and the gear rod 2 87 drives the gear rod 1 84 to move downward through the gear 83. The gear rod 1 84 makes the abutment wheel 86 always fit the outer surface of the cam plate 57 through the abutment rod 85. In addition, the upward movement of the lifting block 64 will also drive the detection through the inclined plate 65. The rod 66 moves upward, and during the upward movement of the detection rod 66, the detection head 69 is driven to move upward synchronously through the spring 2 68. The detection head 69 is no longer in contact with the soil in the seedling tray 4. The detection head 69 moves upward in the cleaning ring 72, and the cleaning ring 72 can scrape the soil on the surface of the detection head 69 to avoid excessive soil adhering to the detection head 69 and affecting subsequent detection, and prevent the detection head 69 from being stuck due to excessive soil adhesion, thereby reducing the inaccuracy in detecting soil compactness and improving the accuracy of air permeability detection.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
