Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal herb seedling technology, specifically a substrate treatment device for Chinese medicinal herb seedling cultivation. Background Technology

[0002] In the process of cultivating Chinese medicinal herbs, the quality of substrate treatment directly affects the growth of seedlings, and substrate treatment equipment is required in the process of substrate treatment.

[0003] Patent publication number CN219478747U discloses a substrate treatment device for Gastrodia elata growth, relating to the technical field of substrate treatment devices. It includes: a treatment box; a placement mechanism disposed within the treatment box; the placement mechanism comprising a rotating component and a placement cylinder; the rotating component being disposed within the treatment box; and a stirring mechanism disposed on the treatment box; the stirring mechanism comprising an installation cylinder, a feeding frame, a connecting component, and two stirring rods; the installation cylinder being fixedly embedded in the top of the outer wall of the treatment box; and the feeding frame being fixedly embedded in the top of the outer wall of the installation cylinder.

[0004] Although the device drives the placement cylinder to rotate inside the treatment box through a rotating component, and can mix the substrate inside the placement cylinder in conjunction with the stirring mechanism, and the sterilization mechanism uses multiple sterilization methods to sterilize the substrate with good sterilization effect and can fully disinfect and sterilize the substrate, the material inside the placement cylinder will locally accumulate during the stirring process, making it impossible to fully mix and disperse the substrate. Moreover, the unloading operation is inconvenient and cannot fully and quickly unload the substrate inside the treatment cylinder. In view of this, we propose a substrate treatment device for Chinese medicinal herb seedling cultivation. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A substrate treatment device for cultivating Chinese medicinal herbs includes a base plate, with several fixed plates above the base plate, and a stirring drum rotatably connected to the fixed plates above the base plate. A discharge mechanism for driving the stirring drum to rotate is provided on the top surface of the base plate.

A feed funnel connected to the inner cavity of the stirring cylinder is fixed near the top of the outer circumference of the stirring cylinder, and a manual valve is installed on the outer wall of the feed funnel.

[0012] These two features enhance the stability of the device during placement, prevent slippage and displacement during use, allow the mixing drum to rotate smoothly during subsequent mixing and unloading operations, provide stable support, make substrate feeding operations more convenient, and enable control over the feeding speed and quantity.

[0013] In a preferred embodiment, the unloading mechanism further includes two fixed rods fixed to the top surface of the base plate near the left end, a guide block slidably connected to the bottom surface of the tilting plate, an electric cylinder with the cylinder body mounted on the top surface of the base plate and the piston rod hinged to the guide block, and the tilting plate is rotatably connected to the two fixed rods through a rotating roller.

[0014] In a preferred embodiment, the bottom surface of the flip plate is provided with a horizontally arranged guide groove, the guide block is slidably connected to the guide groove on the bottom surface of the flip plate, the longitudinal cross-sectional shape of the guide groove on the bottom surface of the flip plate is I-shaped, and the shape of the guide block is I-shaped to match the shape of the guide groove on the bottom surface of the flip plate.

[0015] These two settings allow the mixing drum to tilt for unloading, reducing the difficulty of unloading and making the tilting plate more stable, thus ensuring the safety of the unloading operation.

[0016] In a preferred embodiment, the rotating mechanism further includes a gear coaxially fixed on the outer wall of the rotating rod, a rotating motor mounted on the left side surface of the vertical plate and whose output shaft is coaxially connected to the rotating rod, and the gear meshes with the gear ring.

[0017] This setting allows the mixing drum to rotate stably, aiding in the mixing of the internal matrix.

[0018] In a preferred embodiment, the right side surface of the mixing drum is provided with a baffle mechanism, which includes a baffle that is slidably inserted into the right side surface of the mixing drum, a rotating column that is coaxially fixed to the right side surface of the baffle, an electric push rod whose rod body is installed on the right side surface of the same side fixed plate, and a moving rod that is fixed to the right side surface of the electric push rod piston rod and rotatably connected to the rotating column.

[0019] In a preferred embodiment, the baffle is tightly fitted to the right side surface of the mixing drum, the size of the baffle is adapted to the size of the mixing drum, a plurality of limiting holes are provided on the right side surface of the mixing drum, and a plurality of limiting blocks are fixed on the left side surface of the baffle and slidably inserted into the limiting holes on the same side surface of the right side surface of the mixing drum.

[0020] These two settings make the unloading process controllable and prevent premature spillage of the substrate.

[0021] In a preferred embodiment, the stirring roller penetrates the left side surface of the stirring cylinder and extends into the interior of the stirring cylinder near the right end. Several stirring rods and several spiral blades are located inside the stirring cylinder.

[0022] This feature enables the stirring rod and helical blades to efficiently mix the matrix.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This utility model achieves efficient stirring and thorough mixing of the substrate for Chinese medicinal herb seedling cultivation through the arrangement of a stirring drum, a stirring mechanism, and a rotating mechanism. The stirring mechanism has several stirring rods on the stirring roller that can directly agitate the substrate, while several spiral blades can disrupt the material distribution and prevent local accumulation. The rotating mechanism drives the stirring drum to rotate, changing the position of the material so that the substrate in different parts can be uniformly stirred. The two work together to improve the uniformity of substrate mixing and ensure the stability of substrate quality, providing a high-quality growth foundation for Chinese medicinal herb seedling cultivation.

[0025] 2. This utility model achieves convenient unloading of the substrate inside the mixing drum through the setting of the unloading mechanism and the baffle mechanism. The electric cylinder in the unloading mechanism drives the tilting plate to rotate, causing the mixing drum to tilt. In conjunction with the electric push rod in the baffle mechanism, the opening and closing of the baffle is controlled. When unloading, the baffle is opened, allowing the mixed substrate inside the mixing drum to flow out smoothly. This design achieves the effect of improving unloading efficiency, reducing manual operation intensity and unloading time, while ensuring the controllability of the unloading process, and facilitating the subsequent collection and use of the substrate.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-3 The present invention provides a technical solution: a substrate treatment device for seedling cultivation of Chinese medicinal materials, including a base plate 1, a plurality of fixed plates 2 above the base plate 1, and a stirring cylinder 3 rotatably connected to the plurality of fixed plates 2 above the base plate 1.

[0037] The thickness of the base plate 1 is 2-6cm, and the bottom surface of the base plate 1 is provided with anti-slip texture;

[0038] The thickness of the base plate 1 is preferably 5cm. The anti-slip texture on the base plate 1 significantly increases the friction between the device and the ground. During the mixing and unloading process, it effectively avoids sliding displacement caused by equipment vibration or external force, ensuring that the device always remains stable and providing a solid foundation for the entire substrate treatment process.

[0039] The mixing drum 3 is arranged from left to right, with the right end of the mixing drum 3 being open. A feed funnel 31 connected to the inner cavity is fixed near the top of the outer circumference of the mixing drum 3, and a manual valve 32 is installed on the outer wall of the feed funnel 31.

[0040] The feeding funnel 31 and manual valve 32 set in the mixing drum 3 enable the substrate to enter the mixing drum 3 quickly and conveniently. The manual valve 32 can accurately control the feeding speed and amount, avoiding the substrate from flooding in too much at once and affecting the mixing effect. It also makes it easy to add different components of the substrate as needed, ensuring accurate mixing ratio.

[0041] In this embodiment, as Figures 1-4 As shown, the top surface of the base plate 1 is provided with a discharge mechanism 4 for driving the mixing drum 3 to flip. The discharge mechanism 4 includes a flipping plate 42 rotatably connected to the top surface of the base plate 1, an electric cylinder 44 installed on the top surface of the base plate 1 and used to drive the flipping plate 42 to flip, and several fixing plates 2 fixed on the top surface of the flipping plate 42.

[0042] The unloading mechanism 4 also includes two fixed rods 41 fixed on the top surface of the base plate 1 near the left end, a guide block 45 slidably connected to the bottom surface of the tilting plate 42, an electric cylinder 44 with the cylinder body installed on the top surface of the base plate 1 and the piston rod hinged to the guide block 45, and the tilting plate 42 is rotatably connected to the two fixed rods 41 through the rotating roller 43.

[0043] The electric cylinder 44 in the unloading mechanism 4 drives the tilting plate 42 to tilt, allowing the mixing drum 3 to be quickly adjusted to an inclined state, reducing the difficulty of unloading. Compared with the traditional manual pouring method, electric control is more labor-saving and efficient, and the tilting angle can be precisely controlled according to needs to ensure that the substrate is completely unloaded and reduce residue.

[0044] The bottom surface of the flip plate 42 is provided with a horizontally arranged guide groove. The guide block 45 is slidably connected to the guide groove on the bottom surface of the flip plate 42. The longitudinal cross-sectional shape of the guide groove on the bottom surface of the flip plate 42 is I-shaped, and the shape of the guide block 45 is I-shaped to match the shape of the guide groove on the bottom surface of the flip plate 42.

[0045] By sliding the I-shaped guide groove on the bottom surface of the flip plate 42 with the guide block 45, the guide block 45 slides smoothly along the guide groove during the flipping process, effectively limiting the movement trajectory of the flip plate 42, preventing it from deviating or shaking, ensuring the safety and reliability of the unloading operation, and extending the service life of the equipment.

[0046] In addition, such as Figures 1-2 , Figure 5 As shown, it also includes: a rotating mechanism 5, which is set on the top surface of the flip plate 42 and is used to drive the stirring drum 3 to rotate. The rotating mechanism 5 includes a vertical plate 51 fixed on the top surface of the flip plate 42, a toothed ring 53 coaxially fixed on the outer circumference of the stirring drum 3, and a rotating rod 52 rotatably connected between the vertical plate 51 and the fixed plate 2 on the same side and used to drive the toothed ring 53 to rotate.

[0047] The rotating mechanism 5 also includes a gear 54 coaxially fixed on the outer wall of the circumference of the rotating rod 52, and a rotary motor 55 mounted on the left side surface of the vertical plate 51 with its output shaft coaxially connected to the rotating rod 52. The gear 54 meshes with the gear ring 53.

[0048] The rotating mechanism 5 uses a rotating motor 55 to drive a gear 54 to mesh with a gear ring 53, enabling the mixing drum 3 to rotate stably and continuously. When the mixing mechanism 7 is working, the rotation of the mixing drum 3 allows the internal substrate to continuously change position and fully contact the mixing rod 72 and the spiral blade 73, achieving a more uniform and efficient mixing effect.

[0049] Furthermore, such as Figures 1-2 , Figure 6 As shown, the right side surface of the mixing drum 3 is provided with a baffle mechanism 6. The baffle mechanism 6 includes a baffle 61 that is slidably inserted into the right side surface of the mixing drum 3, a rotating column 63 that is coaxially fixed to the right side surface of the baffle 61, an electric push rod 64 whose rod body is installed on the right side surface of the same side fixed plate 2, and a moving rod 65 that is fixed to the right side surface of the piston rod of the electric push rod 64 and rotatably connected to the rotating column 63.

[0050] The baffle 61 is tightly attached to the right side surface of the mixing drum 3. The size of the baffle 61 is adapted to the size of the mixing drum 3. Several limiting holes are provided on the right side surface of the mixing drum 3, and several limiting blocks 62 that slide and insert into the limiting holes on the same side of the right side surface of the mixing drum 3 are fixed on the left side surface of the baffle 61.

[0051] The opening and closing of the baffle 61 is controlled by the electric push rod 64 in the baffle mechanism 6, so that the unloading process can be effectively controlled. During the mixing process, the baffle 61 is tightly attached to the mixing drum 3 to prevent the matrix from leaking; during unloading, the electric push rod 64 pushes the baffle 61 to open, ensuring that the matrix flows out smoothly and avoiding premature spillage that would cause waste and pollution.

[0052] Specifically, such as Figure 3 , Figure 7 As shown, it also includes: a stirring mechanism 7, which is disposed inside the stirring drum 3 and is used to drive the material inside the stirring drum 3 to stir. The stirring mechanism 7 includes a stirring roller 71 rotatably connected to the stirring drum 3, a plurality of stirring rods 72 and a spiral blade 73 fixed on the outer circumference of the stirring roller 71, and a stirring motor 74 installed on the outer wall of the stirring drum 3 and used to drive the stirring roller 71 to rotate.

[0053] The stirring roller 71 penetrates the left side surface of the stirring drum 3 and extends into the interior of the stirring drum 3 near the right end. Several stirring rods 72 and several spiral blades 73 are located inside the stirring drum 3. Several stirring rods 72 are installed on the outer circumference of the stirring roller 71 in pairs and arranged linearly at equal intervals. Several spiral blades 73 are installed on the outer circumference of the stirring roller 71 in pairs and arranged linearly at equal intervals. The output shaft of the stirring motor 74 is coaxially connected to the stirring roller 71.

[0054] The stirring motor 74 in the stirring mechanism 7 drives the stirring roller 71, causing the stirring rod 72 and the spiral blade 73 to rotate at high speed. The stirring rod 72 directly stirs and breaks up the substrate, while the spiral blade 73 disrupts the material distribution. The two work together to quickly and evenly mix the substrate, significantly improving the substrate treatment efficiency and quality.

[0055] It should be added that the electric cylinder 44, rotary motor 55, electric push rod 64, and stirring motor 74 are all electrically connected to the external PLC via wires, and the electric cylinder 44, rotary motor 55, electric push rod 64, and stirring motor 74 are all electrically connected to the external power supply via wires, and the external PLC is also electrically connected to the external power supply via wires.

[0056] Finally, it should be noted that the electric cylinder 44, rotary motor 55, electric push rod 64, stirring motor 74, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0057] In this embodiment, when feeding is required, the operator opens the manual valve 32, and the substrate enters the mixing drum 3 through the feeding funnel 31; after feeding is completed, the manual valve 32 is closed.

[0058] Subsequently, the external PLC starts the stirring motor 74, which drives the stirring roller 71 to rotate. The stirring rod 72 and the spiral blade 73 stir and disperse the substrate. At the same time, the external PLC controls the rotary motor 55, which drives the stirring drum 3 to rotate through the meshing of the gear 54 and the gear ring 53, so that the substrate is mixed in all directions.

[0059] After mixing is completed, the external PLC controls the electric push rod 64 to retract, causing the baffle 61 to detach from the right side of the mixing drum 3 and open the discharge port; then, the external PLC controls the electric cylinder 44 to push the guide block 45, causing the tilting plate 42 to flip, making the mixing drum 3 tilt, and the internal matrix is ​​smoothly discharged from the opening end; after the discharge is completed, the external PLC controls each component to reset, ready for the next working cycle.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
