Description

Technical Field

[0001] This application relates to the field of agricultural product processing technology, and in particular to a cutting device for planting Dendrobium officinale. Background Technology

[0002] In the cultivation and processing of Dendrobium officinale, cutting is one of the key steps, and its quality and efficiency have a significant impact on subsequent processing and product quality. Traditional methods of cutting Dendrobium officinale mostly involve manual operation or simple mechanical cutting. Manual cutting is not only inefficient and difficult to meet the needs of large-scale production, but also results in poor consistency in cut size, easily leading to material waste. Simple mechanical cutting equipment often suffers from insufficient cutting precision and significant damage to Dendrobium officinale. At the same time, it lacks an integrated design for material screening and conveying, requiring additional manual pre-processing and sorting, increasing labor and time costs.

[0003] A search revealed Chinese Patent Publication No. CN218838018U, which discloses a slicing device for Dendrobium officinale, including a collection box. This slicing device involves placing multiple Dendrobium officinale specimens between a first and a second vertical plate. A threaded rod, in conjunction with a threaded hole, causes the first vertical plate to move to the right, thus securing the Dendrobium officinale. Then, a first cylinder and a first piston rod within a first square block move a lifting plate and the Dendrobium officinale at its bottom downwards, allowing the specimens to move into a limiting frame. A slicing blade at the top of the first horizontal plate then cuts the Dendrobium officinale. The first cylinder then drives the specimens downwards again, allowing for a second cut. This process is repeated until the Dendrobium officinale is divided into multiple segments, achieving a convenient slicing method.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the aforementioned devices lack a screening mechanism, requiring manual pre-treatment of impurities or debris before slitting, increasing operational steps and labor costs; the use of threaded rods to adjust the vertical plate for material fixation results in poor adaptability to different specifications of Dendrobium officinale, and the cylinder-driven feeding suffers from insufficient precision and limited speed adjustment range; the use of contact cutting with slitting blades makes it prone to uneven cuts due to blade wear or improper pressure control, affecting subsequent material growth or processing quality. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a cutting device for Dendrobium officinale cultivation.

[0006] The present application provides a cutting device for Dendrobium officinale cultivation, which adopts the following technical solution: A cutting device for Dendrobium officinale cultivation includes a device shell, a screening and conveying mechanism is provided on one side of the device shell, a feeding mechanism is provided on the other side, and a cutting mechanism is provided between the screening and conveying mechanism and the feeding mechanism.

[0007] The cutting mechanism includes a lifting assembly and a reciprocating drive assembly for driving the lifting assembly. The lifting assembly includes a slide rail fixedly installed at the bottom of the equipment housing, a lifting protrusion slidably connected in the slide rail groove, and a lifting feeding plate for reciprocating feeding. The top of the lifting feeding plate has a cutting groove, and a cutting wire is movably arranged above it. The cutting wire is fixed to the side of the auxiliary feeding box by a cutting wire mounting beam. The bottom of the lifting feeding plate is movably connected to the lifting protrusion by rollers.

[0008] The above solution innovatively adopts a lifting cutting structure, which achieves stable material feeding through precise reciprocating motion control, and completes non-destructive cutting in conjunction with the tensioned cutting line.

[0009] Optionally, the screening and conveying mechanism includes a horizontal conveyor belt, an inclined auxiliary feeding box, and a waste collection box. The top of the auxiliary feeding box is equipped with a 30° inclined screen, and its internal cavity is connected to the waste collection box. The horizontal conveyor belt is located on the discharge side of the auxiliary feeding box, and the cutting line mounting beam is horizontally fixed on the side of the auxiliary feeding box near the feeding mechanism.

[0010] The above solution integrates screening and conveying functions. The inclined screen, combined with the waste collection system, can automatically separate debris and impurities, ensuring the purity of the material.

[0011] Optionally, the feeding mechanism includes symmetrically arranged side baffles, a first guide plate, and a second guide plate. The first guide plate and the second guide plate have a Y-shaped forked structure, wherein the first guide plate extends directly above the cutting groove of the lifting feeding plate.

[0012] Through the above scheme, the Y-shaped guide structure realizes material diversion and positioning, accurately controls the raw material to enter the cutting area, and avoids cutting errors caused by deviation.

[0013] Optionally, the reciprocating drive assembly includes a servo motor, an eccentric wheel, and a connecting rod. The output shaft of the servo motor is mounted on the inner wall of the equipment housing via a bearing seat. The eccentric wheel is fixedly connected to the output end of the servo motor. The two ends of the connecting rod are respectively hinged to the eccentric shaft of the eccentric wheel and the bottom of the lifting protrusion.

[0014] The above scheme employs an eccentric wheel and connecting rod transmission mechanism to achieve stable and reliable reciprocating motion output, ensuring the controllability of the cutting rhythm.

[0015] Optionally, the lifting protrusion is integrally formed from a bottom slide rod and a top single-peak wavy protrusion. The single-peak wavy protrusion rolls in cooperation with the roller, and its thickness is equal to the width of the bottom limiting groove of the lifting feeding plate. The lifting feeding plate is constrained by the limiting baffles on both sides to make vertical reciprocating motion.

[0016] Through the above scheme, the special contour protrusions work in conjunction with the limiting mechanism to convert the rotational motion into precise vertical lifting motion, ensuring the stability of the feed plate's movement trajectory.

[0017] Optionally, the inclined screen of the auxiliary feeding box is provided with a screen hole with a diameter of 3-5mm, and the surface of the horizontal conveyor belt is provided with anti-slip texture.

[0018] The above solution combines the screen mesh size with the anti-slip conveyor belt to effectively separate debris and ensure that there is no slippage during material transport.

[0019] Optionally, the distance between the end of the first guide plate and the cutting groove is 1-3mm, and the extension direction of the second guide plate forms an angle of 15-30° with the conveying direction of the horizontal conveyor belt.

[0020] Through the above scheme, the spacing and angle of the guide plates are optimized to achieve precise material placement and positioning, while forming a smooth material flow path.

[0021] Optionally, the connecting rod is provided with self-lubricating spherical bearings at both ends, the eccentricity of the eccentric wheel is 1 / 2 of the stroke of the lifting feed plate, and the servo motor achieves a reciprocating frequency adjustment of 10-60 times / minute through a frequency converter.

[0022] The above solution reduces frictional losses by using self-lubricating bearings, and, in conjunction with an adjustable drive system, meets the needs of different production cycles.

[0023] Optionally, the cutting wire is a multi-strand twisted metal wire, and its installation tension is controlled by adjusting bolts at both ends of the cutting wire mounting beam. The width of the cutting groove is 0.2-0.5 mm larger than the diameter of the cutting wire.

[0024] The above solution, with its adjustable tension stranded cutting wire and precision cutting groove design, extends service life while ensuring cutting accuracy.

[0025] In summary, this application includes the following beneficial technical effects:

[0026] 1. This utility model incorporates components such as a servo motor, eccentric wheel, connecting rod, lifting protrusion, slide rail, roller, and lifting feeding plate. The servo motor's output shaft drives the eccentric wheel to rotate, which, via the connecting rod, causes the lifting protrusion to slide reciprocally within the slide rail groove. The single-peaked, wave-shaped protrusion at the top of the lifting protrusion, in conjunction with the rolling action of the roller, causes the lifting feeding plate to perform vertical reciprocating motion constrained by a positioning baffle. When the lifting feeding plate rises, its top cutting groove receives the Dendrobium officinale guided by the feeding mechanism; when it descends, it works with fixed cutting wires to complete the cutting. This achieves the effect of stable and continuous cutting of the screened Dendrobium officinale through the cooperation of the reciprocating drive component and the lifting component.

[0027] 2. This utility model incorporates components such as a cutting wire, a cutting wire mounting beam, a cutting groove, and an auxiliary feeding box. The cutting wire mounting beam is horizontally fixed to the side of the auxiliary feeding box, and the tension of the cutting wire is controlled by adjusting bolts. The width of the cutting groove is 0.2-0.5mm larger than the diameter of the cutting wire, ensuring the cutting wire remains taut and precisely aligned with the cutting groove. When the lifting feeding plate carries the Dendrobium officinale to the cutting groove, the material is stably confined below the cutting wire. As the lifting feeding plate descends, the wire quickly cuts the material. This achieves the high-precision, low-loss cutting effect of the device through its precise structural design of the cutting mechanism. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0034] This application discloses a cutting device for planting Dendrobium officinale.

[0035] Please see Figure 1 A cutting device for planting Dendrobium officinale includes a housing 1, a screening and conveying mechanism 2 on one side of the housing 1, a feeding mechanism 3 on the other side, and a cutting mechanism 4 between the screening and conveying mechanism 2 and the feeding mechanism 3.

[0036] Please see Figures 2 to 4 The cutting mechanism 4 includes a lifting assembly and a reciprocating drive assembly for driving the lifting assembly. The lifting assembly includes a slide rail 405 fixedly installed at the bottom of the equipment housing 1, a lifting protrusion 404 slidably connected in the slide groove of the slide rail 405, and a lifting feeding plate 407 for reciprocating feeding. The top of the lifting feeding plate 407 has a cutting groove 408, and a cutting wire 410 is movably arranged above it. The cutting wire 410 is fixed to the side of the auxiliary feeding box 202 through a cutting wire mounting beam 409. The bottom of the lifting feeding plate 407 is movably connected to the lifting protrusion 404 through a roller 406.

[0037] The reciprocating drive assembly includes a servo motor 401, an eccentric wheel 402, and a connecting rod 403. The output shaft of the servo motor 401 is mounted on the inner wall of the equipment housing 1 through a bearing seat. The eccentric wheel 402 is fixedly connected to the output end of the servo motor 401. The two ends of the connecting rod 403 are respectively hinged to the eccentric shaft of the eccentric wheel 402 and the bottom of the lifting protrusion 404.

[0038] The lifting protrusion 404 is integrally formed by the bottom slide rod and the top single-peak wave-shaped protrusion. The single-peak wave-shaped protrusion rolls with the roller 406. Its thickness is equal to the width of the bottom limiting groove of the lifting feeding plate 407. The lifting feeding plate 407 is constrained by the limiting baffles on both sides to make vertical reciprocating motion.

[0039] The connecting rod 403 is equipped with self-lubricating spherical bearings at both ends. The eccentricity of the eccentric wheel 402 is 1 / 2 of the stroke of the lifting feed plate 407. The servo motor 401 achieves reciprocating frequency adjustment of 10-60 times / minute through a frequency converter.

[0040] The cutting wire 410 is a multi-strand twisted metal wire, and its installation tension is controlled by the adjusting bolts at both ends of the cutting wire mounting beam 409. The width of the cutting groove 408 is 0.2-0.5mm larger than the diameter of the cutting wire 410.

[0041] The screening and conveying mechanism 2 includes a horizontal conveyor belt 201, an inclined auxiliary feeding box 202, and a waste collection box 203. The top of the auxiliary feeding box 202 is equipped with a 30° inclined screen, and its internal cavity is connected to the waste collection box 203. The horizontal conveyor belt 201 is set on the discharge side of the auxiliary feeding box 202, and the cutting line mounting beam 409 is horizontally fixed on the side of the auxiliary feeding box 202 near the feeding mechanism 3.

[0042] The inclined screen of the auxiliary feeding box 202 has a screen hole with a diameter of 3-5mm, and the surface of the horizontal conveyor belt 201 is provided with anti-slip texture.

[0043] The feeding mechanism 3 includes symmetrically arranged side baffles 301, a first guide plate 302 and a second guide plate 303. The first guide plate 302 and the second guide plate 303 have a Y-shaped fork structure, wherein the first guide plate 302 extends to the top of the cutting groove 408 of the lifting feeding plate 407.

[0044] The distance between the end of the first guide plate 302 and the cutting groove 408 is 1-3mm, and the extension direction of the second guide plate 303 forms an angle of 15-30° with the conveying direction of the horizontal conveyor belt 201.

[0045] Further explanation is needed: the cutting mechanism 4 is the core execution component of the Dendrobium officinale slicing device, mainly realizing the precise slicing and orderly feeding of Dendrobium officinale. Through the coordinated movement of the reciprocating drive component and the lifting component, it cuts the Dendrobium officinale conveyed by the feeding mechanism 3 according to the set specifications. Specifically, the servo motor 401 drives the eccentric wheel 402 to rotate, which drives the lifting protrusion 404 to reciprocate linearly on the slide rail 405 via the connecting rod 403. Utilizing the rolling cooperation between the top single-peak wave-shaped protrusion and the roller 406, it pushes the lifting feeding plate 407 to make vertical reciprocating motion along the limit baffle. When the lifting feeding plate 407 rises, the Dendrobium officinale in its top cutting groove 408 is cut. Dendrobium officinale is fed below the cutting wire 410, where the tension of multiple strands of twisted metal wire achieves bladeless cutting, reducing material damage. During descent, the material is unloaded, preparing for the next feeding. This mechanism adjusts the speed of the servo motor 401 via a frequency converter to adapt to different production efficiency requirements. The precise design of the width of the cutting groove 408 and the spacing between the guide plates ensures stable positioning of the Dendrobium officinale and a neat cut surface. Furthermore, the vertical reciprocating motion of the lifting feeding plate 407 and the cutting wire 410, combined with the feeding rhythm of the screening and conveying mechanism 2, forms a continuous slitting process, effectively improving slitting efficiency and accuracy, and meeting the standardized slitting requirements for stem segment specifications in Dendrobium officinale cultivation and processing.

[0046] The implementation principle of the slicing device for Dendrobium officinale cultivation in this application embodiment is as follows:

[0047] First, the material is screened and pre-treated. After the Dendrobium officinale to be cut is initially sorted by the feeding mechanism 3, it enters the auxiliary feeding box 202 of the screening and conveying mechanism 2. The top of the 30° inclined screen screens the material to remove impurities and small waste. The waste falls through the screen into the waste collection box 203 connected below. The qualified material slides down the inclined surface of the screen to the horizontal conveyor belt 201.

[0048] Secondly, the material is directionally conveyed and positioned. The horizontal conveyor belt 201, with its anti-slip texture, conveys the screened Dendrobium officinale to the feeding mechanism 3. The symmetrically arranged side baffles 301 constrain the material's direction of travel. The first guide plate 302 and the second guide plate 303 form a Y-shaped fork structure. The first guide plate 302 extends directly above the cutting groove 408 of the lifting feeding plate 407, so that the material is precisely aligned with the center of the cutting groove 408. The second guide plate 303 guides a small amount of offset material back to the main path at an angle of 15-30°.

[0049] Next, the cutting mechanism 4 is powered by a reciprocating drive component. The servo motor 401 of the reciprocating drive component adjusts the frequency through a frequency converter. The output shaft drives the eccentric wheel 402 to rotate. Through the connecting rod 403, which is hinged with self-lubricating joint bearings at both ends, the circular motion is converted into the horizontal reciprocating sliding of the lifting protrusion 404 in the slide rail 405. The top single-peak wave-shaped protrusion of the protrusion rolls and cooperates with the bottom roller 406 of the lifting feed plate 407, driving the feed plate to make vertical reciprocating motion along the limit baffle.

[0050] Next, the lifting and feeding and cutting are executed. When the lifting feeding plate 407 slides up with the protrusion, the cutting groove 408 receives the Dendrobium officinale precisely positioned by the feeding mechanism 3. After rising to the highest point, the feeding plate slides down in the opposite direction with the protrusion. At this time, the cutting wire 410 fixed on the side of the auxiliary feeding box 202 forms a shearing action with the cutting groove 408, quickly cutting the material with a flat cut and low loss.

[0051] Finally, after slitting, the material output and waste disposal are completed. The slitting Dendrobium officinale is lowered to a low position by the feeding plate and transported to the subsequent process by the horizontal conveyor belt 201 on the discharge side of the auxiliary feeding box 202. The small debris generated during the cutting process is filtered twice by the inclined screen of the auxiliary feeding box 202 to ensure the purity of the finished product. The entire process realizes the automated continuous operation of "screening - orientation - drive - cutting - discharge" through mechatronics design.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
