Technical Field
[0001] This invention belongs to the technical field of peanut sprout planting equipment, specifically relating to a motor lifting device and method for peanut sprout planting. Background Technology
[0002] Peanut sprouts, also known as peanut sprouts, are a food with both nutritional and medicinal value, produced after peanuts sprout. They are also called "longevity sprouts." Peanut sprouts can be eaten raw and are exceptionally nutritious. The protein and crude protein content of peanut sprouts ranks first among various vegetables, and they also contain vitamins, potassium, calcium, iron, zinc, and various carbohydrates and nutrients needed by the body, earning them the nickname "longevity fruit sprouts." However, the cultivation of peanut sprouts requires the use of multi-hole planting trays. Current peanut sprout cultivation methods have at least the following drawbacks: the process of inserting peanuts into multi-hole planting trays and transporting them to designated areas currently requires a large amount of manual labor for planting, which is not conducive to reducing production costs and improving production efficiency. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing intelligent automation technology and to provide a lifting device and method for a multi-hole planting plate for peanut sprouts.
[0004] In a first aspect, the present invention provides a lifting device and method for a multi-hole planting plate for peanut sprouts, comprising: a housing, wherein a motor, a lifting drive mechanism, a cam transmission mechanism and a toggle drive mechanism are installed inside the housing. The lifting drive mechanism is used to lift the multi-hole planting plate, and the toggle drive mechanism is used to limit or release the multi-hole planting plate. The lifting drive mechanism and the toggle drive mechanism are driven by the cam transmission mechanism. The cam transmission mechanism is used to coordinate the lifting action and the limiting action to transport the bottom multi-hole planting plate in the planting plate storage area to the transmission belt for conveying.
[0005] The housing is L-shaped and a cam transmission mechanism is installed inside the housing. The cam transmission mechanism includes a first cam and a second cam. The first cam and the second cam are coaxially arranged. After the motor drives the rotating shaft to rotate, the first cam and the second cam move simultaneously. The first cam moves in conjunction with the lifting mechanism, and the second cam moves in conjunction with the toggle drive mechanism.
[0006] The lifting drive mechanism includes a lifting plate, a lifting plate slide rail, and a slider module. The lifting plate is installed on the lifting plate slide rail, and the slider module is installed at the bottom of the lifting plate. The slider module is connected to the protruding area of the first cam. The rotation of the first cam drives the lifting plate to move up and down.
[0007] The turntable drive mechanism includes a drive link, a drive wheel, and a drive chain. The drive link is in contact with the side of the second cam through its end face. The second cam drives the drive link to move, the drive link drives the drive wheel to rotate, the drive wheel drives the drive chain to rotate, and the drive chain drives the turntable to move. The structure of the second cam allows the turntable to cooperate with the lifting action to limit or release the multi-hole planting plate, so that the bottom multi-hole planting plate is conveyed to the transmission belt at certain intervals during the movement, and then conveyed to the next work station for work. The specific drive linkage includes a main drive rod, one end of which is equipped with a drive arm that engages with a second cam. When the second cam rotates to a designated area and contacts the drive arm, it causes the drive arm to rotate at a certain angle, thereby causing the main drive shaft to rotate around its center at a certain angle. The shaft of the main drive rod is mounted on the lifting plate and can change position as the lifting plate rises and falls. The other end of the main drive shaft is connected to a driven shaft, which is equipped with a gear. The gear drives a rack to rotate, thereby causing one side of the lever to rotate at a certain angle. An auxiliary drive rod is also provided on the main drive rod, which is used to drive the other side of the lever to rotate.
[0008] The motor-driven lifting device for peanut sprout cultivation is installed on one side of the conveyor belt, which is located on the frame. A peanut conveyor belt is set up side by side with the conveyor belt. A robotic arm and a vision processing system are installed above the frame. The vision processing system uses a camera to transmit the image of the multi-hole planting plate to the backend in real time. After processing the image data, it outputs instructions to the robotic arm, which then picks up the peanuts from the peanut conveyor belt and places them into the slots on the multi-hole planting plate. Once the multi-hole planting plate is full of peanuts, it is transported by the conveyor belt to a designated area for peanut sprout cultivation.
[0009] Secondly, the present invention provides a method for operating a motor lifting device for peanut sprout planting as described in the first aspect, characterized in that a lifting drive mechanism performs lifting and lowering actions on a multi-hole planting plate, a plate-shifting drive mechanism limits or releases the multi-hole planting plate, and the lifting drive mechanism and the plate-shifting drive mechanism are driven by a cam transmission mechanism. The cam transmission mechanism is used to coordinate the lifting and lowering actions with the limiting actions to transport the bottom multi-hole planting plate in the multi-hole planting plate storage area to the transmission belt for conveying.
[0010] The beneficial effects of this invention include: This invention provides a motor-driven lifting device for peanut sprout cultivation, comprising: a housing, inside which a motor, a lifting drive mechanism, a cam transmission mechanism, and a toggle drive mechanism are installed. The lifting drive mechanism is used to lift the multi-hole planting plate, and the toggle drive mechanism is used to limit or release the multi-hole planting plate. The lifting drive mechanism and the toggle drive mechanism are driven by the cam transmission mechanism. The cam transmission mechanism enables the lifting and limiting actions to work together to transport the bottom multi-hole planting plate in the multi-hole planting plate storage area to the transmission belt for conveying. The entire device has high efficiency and good stability, and is driven purely by a mechanical structure, eliminating the need for an additional electrical control system. This effectively reduces the cost of the device while improving its reliability, significantly reducing maintenance costs, and greatly improving efficiency. Attached Figure Description

[0013] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0014] Example 1 This invention discloses a motor-driven lifting device for peanut sprout cultivation, comprising: a housing 101, inside which are installed a motor 108, a lifting drive mechanism 102, a cam transmission mechanism 103, and a turntable drive mechanism. The motor 108 drives the cam transmission mechanism 103 to rotate, and the motor 108 uses chain drive. The lifting drive mechanism 102 is used to lift the multi-hole planting plate 2, and the turntable drive mechanism is used to limit or release the multi-hole planting plate 2. The lifting drive mechanism 102 and the turntable drive mechanism are driven by the cam transmission mechanism 103. The cam transmission mechanism 103 enables the lifting and limiting actions to work together to transport the bottom multi-hole planting plate 2 from the storage area to the transmission belt for conveying. The entire device has high efficiency and good stability, and is driven purely by mechanical structure, requiring no additional electrical control system. This effectively reduces the cost of the device while improving its reliability, significantly reducing maintenance costs, and greatly improving efficiency.
[0015] The housing 101 is L-shaped, and a cam transmission mechanism 103 is installed inside the housing 101. The cam transmission mechanism 103 includes a first cam 110 and a second cam 111, which are coaxially arranged. After the motor 108 drives the rotating shaft to rotate, the first cam 110 and the second cam 111 move simultaneously. The first cam 110 cooperates with the lifting drive mechanism 102, and the second cam 111 cooperates with the toggle drive mechanism. The lifting drive mechanism 102 includes a lifting plate 104, a lifting plate slide rail, and a slider module 105. The lifting plate 104 is mounted on the lifting plate slide rail, and the slider module 105 is installed at the bottom of the lifting plate 104. The slider module 105 is connected to the protruding area of the first cam 110. The rotation of the first cam 110 drives the lifting plate 104 to move up and down.
[0016] The turntable drive mechanism includes a drive link 112, a drive wheel 109, and a drive chain 107. The drive link 112 is in contact with the side of the second cam 111 through its end face. The second cam 111 drives the drive link 112 to move, the drive link 112 drives the drive wheel 109 to rotate, the drive wheel 109 drives the drive chain 107 to rotate, and the drive chain 107 drives the turntable 106 to move. Through the structural setting of the second cam 111, the turntable 106 can cooperate with the lifting action to limit or release the multi-hole planting plate 2, so that the bottom multi-hole planting plate 2 is conveyed to the transmission belt at certain intervals during the movement, and then conveyed to the next work station for work.
[0017] Specifically, the drive linkage 112 includes a main drive rod, one end of which is equipped with a drive rod that can cooperate with the second cam 111. When the second cam 111 rotates to a designated area and contacts the drive rod, it drives the drive rod to rotate at a certain angle, thereby causing the main drive shaft to rotate around the center at a certain angle. The shaft of the main drive rod is mounted on the lifting plate 104 and can change position as the lifting plate 104 rises and falls. The other end of the main drive shaft is connected to the driven shaft, which is equipped with a gear. The gear drives the rack to rotate, thereby driving one side of the lever plate 106 to rotate at a certain angle. An auxiliary drive rod is also provided on the main drive rod, which is used to drive the other side of the lever plate 106 to rotate.
[0018] The motor-driven lifting device 1 for peanut sprout cultivation is installed on one side of the conveyor belt, which is located on the frame. A peanut conveyor belt is arranged parallel to the conveyor belt. A robotic arm and a vision processing system are installed above the frame. The vision processing system uses a camera to transmit the image of the multi-hole planting plate 2 to the backend in real time. After processing the image data, it outputs instructions to the robotic arm, which controls the robotic arm to pick up peanuts from the peanut conveyor belt and place them into the slots on the multi-hole planting plate 2. After the multi-hole planting plate 2 is filled with peanuts, it is transported by the conveyor belt to a designated area for peanut sprout cultivation.
[0019] The housing adopts an L-shaped one-piece molding structure, made of Q235 steel plate through bending and welding. The overall height is set at 1000mm, the width is 600mm, and the steel plate thickness is 10mm, ensuring that the housing has sufficient load-bearing capacity and rigidity to stably support the various drive mechanisms and stacked multi-hole planting plates. On the outside of the housing, corresponding to the installation positions of the motor and transmission shaft, there are two removable maintenance covers. The maintenance covers are 300mm×250mm and 250mm×200mm in size, respectively. They are fixed to the housing with M8×20 bolts with a bolt spacing of 80mm, facilitating subsequent inspection, maintenance, and replacement of internal mechanisms. Four reinforcing ribs are welded to the inner side of the housing corresponding to the installation positions of the lifting drive mechanism and the cam transmission mechanism. The reinforcing ribs are made of 50mm×50mm×5mm angle steel, and their length is adapted to the corresponding installation area. The reinforcing ribs are fully welded to the inner wall of the housing, and the weld height is 5mm. This effectively enhances the rigidity of the inner wall of the housing and prevents the housing from deforming during operation, which would affect the matching accuracy of each mechanism.
[0020] The top inner side of the casing features a multi-well implantation plate storage area. This area has a rectangular cavity structure with a width of 410mm, a length of 460mm, and a height of 650mm, capable of stably stacking 12 standard-sized multi-well implantation plates. At each of the four corners of the storage area's inner wall, a guide strip is fixed. These guide strips are made of 304 stainless steel, are 2.5mm thick, and 650mm long, matching the height of the storage area. The guide strips are fixed to the inner wall of the storage area with M6×15 bolts spaced 100mm apart. The inner surface of the guide strip slides smoothly against the side of the multi-well implantation plate, with a gap controlled at 1-2mm. This serves both a guiding function, ensuring the multi-well implantation plates are stacked neatly, and preventing excessive gaps that could cause plate misalignment or insufficient gaps that could cause slippage.
[0021] The specific implementation structure and assembly of the cam transmission mechanism include a first cam, a second cam, and a transmission shaft. The transmission shaft is made of 45# steel, with a diameter of 25mm and a length of 550mm, which is adapted to the width of the machine housing. 6204 model deep groove ball bearings are respectively installed at both ends of the transmission shaft. The outer ring of the bearing is interference-fitted with the bearing mounting seat pre-set on the inner wall of the machine housing. The bearing mounting seat is fixed to the inner wall of the machine housing by bolts to ensure that the transmission shaft can rotate flexibly around its own axis without obvious shaking during rotation, and the runout is controlled within 0.1mm.
[0022] Both the first and second cams are made of 45# steel with a chrome-plated surface, the thickness of which is 0.05-0.1mm. This enhances the wear resistance and corrosion resistance of the cam surface, extending its service life. The first cam is an eccentric cam with a contour radius of 60mm and an eccentricity of 25mm, capable of driving the lifting plate to achieve a lifting stroke of 50mm (suitable for the thickness of multi-hole planting plates and the height of the conveyor belt). The second cam is a grooved cam with a contour radius of 50mm and a groove width of 18mm, matching the diameter of the roller at the end of the drive rod (the roller diameter is 17mm), ensuring that the roller can roll smoothly within the groove without jamming. The first and second cams are fixedly connected to the transmission shaft by a flat key, model GB / T1096-2003, with specifications of 10×8×25mm. The phase difference between the two cams is strictly controlled to 90°. After marking and positioning, they are welded and reinforced to ensure synchronization during rotation, achieving precise coordination between lifting and limiting actions.
[0023] One end of the drive shaft extends 50mm to the outside of the housing and is connected to the motor output shaft via an HL2 type flexible pin coupling. Both ends of the coupling are fixed to the drive shaft and motor output shaft respectively via flat keys. The flexible pin is made of polyurethane, model M8×30mm, which buffers vibrations during motor operation and prevents vibrations from being transmitted to the cam drive mechanism, thus affecting transmission accuracy. The motor is a Y-series three-phase asynchronous motor, model Y90L-4, with a power of 1.1kW and a speed of 1440r / min. The motor is fixed to the inside of the bottom of the housing via a U-shaped motor bracket. The motor bracket is welded from Q235 steel plate, with a height of 150mm, and is fixed to a pre-embedded steel plate welded to the bottom of the housing using M10×30 bolts. The motor housing is integrally formed with heat sinks, with a spacing of 10mm and a thickness of 2mm, ensuring effective heat dissipation during long-term motor operation and preventing overheating damage.
[0024] The specific implementation structure and assembly of the lifting drive mechanism include a lifting plate, a lifting plate slide rail, a slider module, and a return spring. The lifting plate is made of Q235 rectangular steel plate with a thickness of 7mm, a length of 450mm, and a width of 400mm, which is perfectly matched to the size of the multi-hole planting plate. A 4mm thick anti-slip rubber pad is pasted on the upper surface of the lifting plate. The rubber pad is made of nitrile rubber with a Shore hardness of 60-70 degrees and is fixed to the lifting plate with strong adhesive (model 502 strong adhesive). The surface of the rubber pad is provided with evenly distributed anti-slip textures with a texture depth of 1mm and a spacing of 10mm, which can increase the friction with the bottom of the multi-hole planting plate and prevent the planting plate from sliding and deviating during the lifting plate's ascent or descent.
[0025] The lifting plate slide rail uses SK16 linear slide rails, 900mm in length. Two slide rails are symmetrically arranged on both sides of the inner side of the housing. The installation height of the slide rails is adapted to the height of the transmission shaft, ensuring that the first cam can accurately contact the contact block at the bottom of the slider module. The slide rails are fixed to the inner wall of the housing with M8×25 bolts, with a bolt spacing of 150mm. The parallelism error of the slide rail installation is controlled within 0.05mm / m to prevent the slide rail from tilting and causing the lifting plate to slide and jam. Each slide rail is equipped with two sets of slider modules, for a total of four sets, which are symmetrically arranged at the four corners of the bottom of the lifting plate. The slider modules are fixed to the bottom of the lifting plate by full welding, with a weld height of 6mm, to ensure a firm connection and the ability to withstand the weight of the multi-hole planting plate (the weight of a single planting plate is about 2kg, and the total weight of 12 stacked plates is about 24kg).
[0026] A cam contact block is welded to the bottom of the slider module. The contact block is a hemispherical structure with a diameter of 20mm, made of 45# steel, and its surface is hardened to a hardness of HRC45-50 to enhance its wear resistance and prevent wear caused by long-term contact with the cam. The center of the contact block is aligned with the contour surface of the first cam, ensuring that the slider module can be smoothly pushed up and down by the contact block when the first cam rotates. The return spring is a cylindrical helical compression spring of GB / T2089-2009 standard, with a spring wire diameter of 5mm, a free length of 120mm, and a total of 10 turns. Two return springs are symmetrically arranged on both sides of the bottom of the lifting plate, 50mm away from the edge of the lifting plate. One end of the spring is welded to the bottom of the lifting plate, and the other end is welded to a spring seat on the bottom of the housing. The spring seat is made of Q235 steel plate with a thickness of 10mm to ensure uniform force during the extension and contraction of the spring. The spring force of the return spring is set to 500N, which can smoothly push the lifting plate downward to return to its original position after the first cam disengages from the contact block, without obvious impact during the return process.
[0027] The specific implementation structure and assembly of the paddle drive mechanism include a drive linkage, a drive wheel, a drive chain, a paddle, and a paddle bracket. The drive linkage consists of a main drive rod, an auxiliary drive rod, and a drive rod, all made of 45# steel. The main drive rod is a cylindrical structure with a diameter of 22mm and a length of 350mm. A drive rod with a diameter of 18mm and a length of 90mm is vertically welded to one end. The end of the drive rod away from the main drive rod is connected to a roller via an M6×20 pin. The roller is made of 45# steel with a diameter of 17mm and a thickness of 10mm. The roller can rotate flexibly around the pin, with a rotational resistance of less than 5N.
[0028] The middle part of the main drive rod is fixed to the upper surface of the lifting plate via a UCP205 deep groove ball bearing seat. The bearing seat is fixed to the lifting plate with M8×20 bolts at a spacing of 60mm. The bearing inside the bearing seat has an interference fit with the main drive rod, ensuring that the main drive rod can rotate freely around the bearing seat without jamming or shaking during rotation. The end of the main drive rod away from the drive rod is connected to the driven shaft via an SWC100 universal coupling. The universal coupling can compensate for installation deviations between the main drive rod and the driven shaft, ensuring stable power transmission. The driven shaft has a diameter of 20mm and a length of 400mm. Both ends are fixed to the upper surface of the lifting plate via bearing seats. Each end of the driven shaft has a coaxially fixed drive wheel. The drive wheel is a sprocket, model 08B-1, with 18 teeth. The drive wheel and the driven shaft are fixed with a flat key, model 8×6×20mm.
[0029] A drive chain, model 08B-1, is fitted to the outer side of the drive wheel. The chain tension is controlled by adjusting the bearing position of the driven shaft, ensuring smooth chain operation without loosening or skipping teeth. Two lever brackets are welded to the drive chain, symmetrically distributed at both ends of the lifting plate. These L-shaped brackets are made of Q235 steel plate, 6mm thick, with a horizontal section length of 80mm and a vertical section length of 100mm. The horizontal section is welded to the drive chain, and the vertical section is welded perpendicularly to the lever. The lever is made of Q235 rectangular steel plate, 400mm long, 25mm wide, and 5mm thick. The top of the lever has a 6mm radius chamfer to prevent scratching the edges of the multi-hole planting plate during extension and retraction. The lever height is set at 80mm to effectively limit the movement of the multi-hole planting plate.
[0030] The specific implementation structure of the conveyor belt is as follows: the conveyor belt is made of PVC, with a width of 450mm and a thickness of 2.5mm. The surface of the conveyor belt is provided with anti-slip texture to enhance the friction with the multi-hole planting board, prevent the planting board from sliding during the conveying process, and ensure that the multi-hole planting board can slide smoothly from the lifting plate onto the conveyor belt without drop impact.
[0031] The conveyor belt is driven by two rollers, each 80mm in diameter and 500mm in length. Both ends of the rollers are fixed to the conveyor belt support frame via bearing seats. The conveyor belt support frame is made of Q235 steel plate and is 500mm high, matching the highest lifting position of the lifting plate. One roller is connected to the motor output shaft via a chain (model 08B-1) with a tooth count matching the sprocket on the roller, ensuring the conveyor belt speed is controlled at 0.8m / s to match the rhythm of subsequent planting processes. Baffles, 60mm high and made of Q235 steel plate with a thickness of 4mm, are installed on both sides of the conveyor belt. The baffles are welded to the conveyor belt support frame, with a 5mm gap between the inner side of the baffle and the edge of the conveyor belt to prevent the multi-hole planting plate from slipping off the sides of the conveyor belt.
[0032] In this embodiment, the device adopts a purely mechanical transmission structure. A cam transmission mechanism achieves precise coordination between the lifting drive mechanism and the toggle drive mechanism, eliminating the need for additional electrical control systems (such as sensors and controllers). This effectively reduces manufacturing and maintenance costs while improving operational reliability and preventing downtime due to electrical faults. The device's conveying efficiency reaches 257 pieces / hour, more than three times higher than manual handling (approximately 60 pieces / hour). The conveying process is smooth and does not damage the multi-hole planting plate, making it suitable for the large-scale cultivation of peanut sprouts.
[0033] Example 2 This embodiment provides a working method for a motor lifting device for peanut sprout planting. The lifting drive mechanism lifts and lowers the multi-hole planting plate, and the toggle drive mechanism limits or releases the multi-hole planting plate. The lifting drive mechanism and the toggle drive mechanism are driven by a cam transmission mechanism. The cam transmission mechanism enables the lifting and limiting actions to work together to transport the bottom multi-hole planting plate in the multi-hole planting plate storage area to the transmission belt for conveying.
[0034] The operation process of the device (i.e., the specific implementation of the lifting method) in this embodiment is as follows: The entire process is automated and requires no manual intervention. Step 1: Device assembly and debugging: Assemble the above-mentioned components into the machine housing according to the above parameters and assembly requirements. After assembly, debugging is performed. First, manually rotate the transmission shaft to check whether the first cam and the second cam rotate flexibly and whether the lifting plate slides smoothly on the slide rail without jamming or shaking. Then check whether the extension and retraction of the dial plate is normal and whether the drive chain runs smoothly without loosening or skipping teeth. Next, check the elasticity of the return spring to ensure that the lifting plate can return smoothly under the action of the spring. Finally, start the motor and run it unloaded for 5 minutes to check whether the motor runs smoothly, whether the transmission of each mechanism is synchronized, and whether the vibration and noise are within a reasonable range (noise ≤ 60dB). After successful debugging, the 12 multi-hole planting plates are neatly stacked in the storage area, ensuring that the planting plates are in contact with the guide strips and that the bottom multi-hole planting plate is in close contact with the anti-slip rubber pad on the upper surface of the lifting plate. At this time, the lever is in the extended state, and the top of the lever contacts the bottom of the second to last planting plate, limiting the remaining planting plates and preventing them from slipping.
[0035] Step 2, Start the device: Connect the motor power supply, the motor starts running, the motor output shaft rotates at a speed of 1440 r / min, and drives the transmission shaft to rotate synchronously through the elastic pin coupling. The transmission shaft drives the first cam and the second cam, which are fixed on the same axis, to rotate synchronously. Since the phase difference between the two is 90°, the lifting action and the limit action are coordinated in an orderly manner, ensuring a smooth conveying process.
[0036] Step 3, Lifting Plate Ascent: As the protruding area of the first cam gradually contacts the hemispherical contact block at the bottom of the slider module, the cam continues to rotate, generating an upward thrust on the contact block. This pushes the slider module upward along the linear guide rail, causing the lifting plate to move upward synchronously. At this time, the return spring is compressed, generating elastic deformation and storing elastic potential energy. During the upward movement of the lifting plate, the bottom multi-hole planting plate rises synchronously. Since the push plate is in the extended state at this time, it limits the remaining 11 planting plates in the storage area, preventing them from rising with the lifting plate and ensuring that only one planting plate is delivered at a time. The lifting plate rises at a speed of 0.1 m / s, with a stroke of 50 mm, smoothly and without impact throughout, taking 0.5 seconds.
[0037] Step 4, retracting the paddle plate and releasing the limit: When the lifting plate rises to its highest position, the protruding area of the first cam is in complete contact with the contact block. At this time, the lifting plate stops rising, and the bottom of the bottom multi-hole planting plate is flush with the conveyor belt surface. At the same time, the second cam rotates exactly 90°, and the inclined surface of its groove pushes the roller at the end of the drive rod, causing the drive rod to swing upward around the axis of the main drive rod. The drive rod drives the main drive rod to rotate clockwise around the bearing seat (viewed from the front of the device). The main drive rod drives the driven shaft to rotate synchronously through the universal coupling. The driven shaft drives the drive wheels at both ends to rotate. The drive wheels drive the paddle plate bracket to retract inward through the drive chain. The paddle plate bracket drives the paddle plate to retract synchronously. The paddle plate disengages from the bottom of the planting plate, releasing the limit on the bottom multi-hole planting plate. The retraction stroke of the paddle plate is 30mm, taking 0.2 seconds.
[0038] Step 5, Planting Board Conveying: After the limiting plate is released, the bottom multi-hole planting board, under its own weight (approximately 2kg), smoothly slides from the lifting plate onto the conveyor belt. Since the lifting plate and the conveyor belt are flush and both have anti-slip surfaces, the planting board slides without impact or deviation. After sliding onto the conveyor belt, the planting board is transported to the subsequent process at a speed of 0.8m / s, completing the conveying of a single planting board.
[0039] Step Six: Lifting Plate Reset and Paddle Extension: The first cam continues to rotate, and its protruding area gradually disengages from the contact block. At this time, the reset spring recovers its elastic deformation, releases elastic potential energy, and pushes the lifting plate to smoothly reset downwards along the linear slide rail. The reset speed of the lifting plate is 0.1m / s, taking 0.5 seconds, resetting to the initial position (450mm from the bottom of the housing). Simultaneously, the second cam continues to rotate 90°, and the roller returns to the bottom of the groove of the second cam. The drive rod swings downwards under its own weight and the action of the cam, driving the main drive rod to rotate counterclockwise. This, in turn, drives the paddle bracket to extend outwards through the driven shaft, drive wheel, and drive chain. The paddle extends synchronously, re-contacting the bottom of the new bottommost multi-hole planting plate (the original second to last piece) in the storage area, limiting its movement, and completing one complete lifting and conveying cycle. The entire cycle takes approximately 1.4 seconds.
[0040] Step 7, Continuous Conveying: Repeat steps 3 to 6 above.
