Description

Technical Field

[0001] This invention relates to the field of automated sowing machinery technology for Pinellia ternata, and particularly to a sowing device for planting Pinellia ternata. Background Technology

[0002] Pinellia ternata has the effects of drying dampness and resolving phlegm, relieving nausea and vomiting, and has significant efficacy in treating various diseases such as esophageal cancer and gastric cancer. With the rapid development of the Chinese medicinal herb industry, the scale of Pinellia ternata cultivation is constantly expanding, and the demand for its mechanized sowing equipment is becoming increasingly prominent.

[0003] Existing Pinellia ternata seeders typically include components such as a frame, walking mechanism, seed box, seed metering device, furrow opener, seed delivery pipe, soil covering device, and press roller, and are equipped with a power and transmission system to achieve their operational functions. The seed box is used to store Pinellia ternata seed stems; the seed metering device is responsible for discharging the seed stems quantitatively and at fixed intervals, which are then guided through the seed delivery pipe to the furrows opened by the furrow opener; the soil covering device then performs the soil covering operation; the press roller compacts the soil, promoting contact between the seed stems and the soil, which is beneficial for germination.

[0004] However, in actual operation, due to factors such as humidity, the stems of Pinellia ternata easily stick together and clump, which not only blocks the connection between the seed box and the seed metering device, causing seed metering interruption, but also hinders the uniform flow of the stems, affecting the accuracy and continuity of seed metering. Therefore, there is an urgent need for a device that can continuously stir and break up clumps to improve the reliability and operation quality of the seeder. Summary of the Invention

[0005] The purpose of this invention is to provide a sowing device for planting Pinellia ternata, which has the effect of continuously stirring and breaking up clumps of Pinellia ternata seed stems in the seed box.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a sowing device for planting Pinellia ternata, comprising a traction frame, traveling wheels rotating at the front of the traction frame, a seed box fixed to the top of the traction frame and storing seeds, a seed dispensing mechanism installed at the bottom of the seed box and discharging seeds from the seed box at fixed intervals and in fixed quantities, a furrowing mechanism installed at the bottom of the traction frame and creating seed furrows in the ground, a seed conveying pipe connecting the seed dispensing mechanism and the furrowing mechanism, a soil covering mechanism installed at the bottom of the traction frame and backfilling soil into the seed furrows to bury the seeds, and a rolling mechanism rotating at the rear of the traction frame and compacting the soil. The soil pressing roller, the seed dispensing mechanism, and the driving mechanism for the operation of the soil pressing roller are included. The seed box is equipped with a seed stirring and dispersing mechanism. The seed stirring and dispersing mechanism includes a pair of vertically located and sliding plates inside the seed box, a sliding assembly that drives the two moving plates to slide back and forth linearly inside the seed box, a synchronization rod that is horizontally located inside the seed box and fixedly connected to one side of the two moving plates at both ends, a rotating cylinder that is rotatably sleeved on the synchronization rod, multiple stirring rods that are evenly arranged around the axis of the rotating cylinder and fixedly connected to the outer wall of the rotating cylinder at one end, and a rotating assembly that drives the rotating cylinder to rotate relative to the synchronization rod.

[0007] By adopting the above technical solution, when the above device sows Pinellia ternata, the rotating mechanism in the seed stirring and unblocking mechanism will drive the rotating cylinder to rotate, so that the stirring rod on the outer wall of the rotating cylinder stirs the Pinellia ternata seed stems inside the seed box. At the same time, the moving component drives the moving plate to move back and forth inside the seed box, so that the rotating cylinder and the stirring rod stir all the Pinellia ternata seed stems in the seed box. This not only effectively prevents the Pinellia ternata seed stems from sticking together and clumping, so as to ensure that the Pinellia ternata seed stems flow smoothly into the seed dispensing mechanism, but also rakes and flattens the top of the Pinellia ternata seed stems in the seed box, so as to ensure that the Pinellia ternata seed stems in the seed box flow evenly into each seed dispensing chamber of the seed dispensing mechanism.

[0008] A further configuration of the present invention is as follows: the soil compaction roller includes a pair of vertically parallel rolling discs, a pair of support shafts respectively fixedly connected to the opposite sides of the two rolling discs, and a plurality of rolling rods uniformly surrounding the axis of the support shafts and connected at both ends to the outer walls of the two support discs respectively. A pair of vertical support plates are fixedly provided at the bottom of the traction frame, and the two support shafts are respectively rotatably connected to the two support plates. The rolling discs and the support shafts are coaxial, and the distance between the center line of the rolling rods and the center line of the support shafts is not less than the radius of the rolling discs.

[0009] By using the aforementioned soil compaction roller, not only can the backfill soil be effectively compacted, but the cage-like structure formed by the combination of the rolling disc and rolling rod can also prevent it from slipping and sticking to the soil, ensuring that it can roll smoothly in the field.

[0010] A further configuration of the present invention is as follows: the seed metering mechanism includes multiple seed metering chambers spaced apart at the bottom of the seed box and communicating with the inside of the seed box; multiple seed metering wheels rotatably disposed in each seed metering chamber; multiple seed metering grooves evenly opened on the outer wall of the seed metering wheels; and a rotating shaft that rotates horizontally through all the seed metering chambers and connects to the seed metering wheels therein. The seed metering chamber includes a feeding chamber and a discharging chamber, with the top of the seed metering wheel located in the feeding chamber and the bottom of the seed metering wheel located in the discharging chamber. The width of the feeding chamber, the width of the discharging chamber, and the radius of the seed metering wheel decrease sequentially, and the width of the discharging chamber is close to the radius of the seed metering wheel. The bottom of the discharging chamber is open and connected to a seed delivery pipe. The rotating shaft and the seed metering wheel are coaxial. The driving mechanism drives the rotating shaft and the support shaft to rotate. A pair of vertical support plates are fixedly disposed on the top of the traction frame, and the two ends of the rotating shaft are rotatably connected to the two support plates. The seed box is located between the two support plates, and its two ends are fixedly connected to the two support plates facing each other.

[0011] By employing the aforementioned seed metering mechanism, when quantitative seed metering is required, the drive mechanism will drive the rotating shaft to rotate, causing the rotating shaft to rotate all the seed metering wheels in the seed metering chamber. Since the radius of the seed metering wheel is smaller than the width of the feeding chamber and closer to the width of the discharging chamber, before the seed metering wheel rotates, the Pinellia ternata seed stems falling from the seed box into the feeding chamber cannot directly pass through the narrow gap between the side of the seed metering wheel and the inner wall of the discharging chamber to enter the discharging chamber. However, during the rotation of the seed metering wheel, a single or a small number of Pinellia ternata seed stems in the feeding chamber can fall into the seed metering groove on the outer wall of the seed metering wheel and follow the seed metering wheel to enter the discharging chamber in sequence, thereby achieving the effect of quantitative seed metering.

[0012] A further configuration of the present invention is as follows: the ditching mechanism includes multiple ditching plows arranged at intervals, multiple seed-spreading tubes respectively fixedly connected to the ditching plows, multiple square tubes respectively fixedly supporting the seed-spreading tubes, and fasteners vertically fastening the square tubes to the traction frame. The ditching plows are located below the square tubes, the seed-spreading tubes are fixed to one side of the square tubes, the top opening of the seed-spreading tubes is connected to the seed delivery tube, and the bottom outlet of the seed-spreading tubes is located in the middle of the concave surface of the ditching plows. The fasteners include a U-shaped plate, a pair of U-bolts, and two pairs of fastening nuts. The U-shaped plate holds the square tube, and the two U-bolts together hold the crossbeam of the traction frame and are located on both sides of the square tube. The two external threads of the U-bolts pass through the edge of the U-shaped plate and are respectively threaded to the fastening nuts. By adopting the above-mentioned ditching mechanism, not only can planting furrows for pre-buried Pinellia ternata seedlings be effectively opened in the field, but also, in conjunction with the fasteners connecting and fixing the square tubes to the traction frame, the user can easily adjust the height of the ditching plows to adapt to different furrow depths.

[0013] A further configuration of the present invention is as follows: the drive mechanism includes a motor fixed to a traction frame, a sprocket one fixedly connected to the output end of the motor, a sprocket two fixedly connected to a rotating shaft, a chain one mounted on sprocket one and sprocket two, a pair of coaxial drive shafts one and two rotatably mounted on one side of support plate one and support plate two respectively, a pair of bevel gears one and two fixedly connected to support shaft and rotating shaft respectively, a pair of bevel gears three and four fixedly connected to drive shaft one and drive shaft two respectively and meshing with bevel gears one and two respectively, a drive cylinder slidably sleeved on drive shaft one and drive shaft two, a limiting ring fixed inside the drive cylinder, and a spring one fixedly connected at both ends to drive shaft two and limiting ring respectively;

[0014] The first drive shaft includes a splined section and a pair of drive sections connected to the two ends of the splined section. The second drive shaft includes a splined section and a pair of drive sections connected to the two ends of the splined section. The inner wall of the drive cylinder has spline grooves 1 and 2 that respectively engage with the splined section 1 and the splined section 2. The limiting ring is located between the spline groove 1 and the spline groove 2. The spring is sleeved on the drive section 2, and the two ends of the spring are connected to the splined section 1 and the limiting ring respectively. The inner diameter of the limiting ring is equal to the outer diameter of the drive section 1 and the drive section 2, and the ends of the drive section 1 and the drive section 2 slide into the limiting ring.

[0015] A protective cover 1 is fixedly installed on one side of the support plate 1 to protect bevel gear 1 and bevel gear 3, and the support shaft and transmission part 1 rotate through the protective cover 1 to connect bevel gear 1 and bevel gear 3 respectively; a protective cover 2 is fixedly installed on one side of the support plate 2 to protect bevel gear 2 and bevel gear 4, and the rotating shaft and transmission part 2 rotate through the protective cover 2 to connect bevel gear 2 and bevel gear 4 respectively.

[0016] By employing the aforementioned drive mechanism, when it is necessary to drive the rotating shaft and support shaft to rotate, the motor first drives sprocket one to rotate, which in turn drives the rotating shaft to rotate via chain one and sprocket two. Then, the rotating shaft drives bevel gear two to rotate and mesh with bevel gear four, which in turn drives transmission shaft two to rotate. Since the splined part one of transmission shaft one and the splined part two of transmission shaft two are respectively engaged with the splined groove one and splined groove two inside the transmission cylinder, the transmission cylinder and transmission shaft two will rotate synchronously with transmission shaft one. Finally, transmission shaft one drives bevel gear three to rotate and mesh with bevel gear one, which in turn drives the support shaft to rotate, thereby achieving synchronous operation of the soil compaction roller and the seeding mechanism. The transmission connection structure of drive shaft one, drive shaft two, and drive cylinder not only stably transmits power but also adapts to various field environments, making manual maintenance and cleaning easy and convenient. The spring one and limit ring inside the drive cylinder allow users to quickly disassemble and assemble the above-mentioned transmission structure (disassembly method: manually lift the drive cylinder upwards to disengage the drive cylinder and drive shaft two from each other; installation is the opposite), to disconnect and connect the transmission of drive shaft one and drive shaft two, thereby facilitating the maintenance and repair of easily worn parts such as seeding mechanisms or soil pressing rollers. Protective covers one and two not only prevent soil impurities from contaminating and wearing the spur gears, thus protecting the meshing transmission safety of the spur gears, but also support the stable rotation of drive shaft one and drive shaft two.

[0017] A further configuration of the present invention is as follows: the soil covering mechanism includes a pair of swing arms that are hinged to the bottom of the traction frame at one end, a soil covering rod that is fixedly connected to the other ends of the two swing arms at both ends, a pair of support arms that are hinged to the other ends of the two swing arms at one end, a pair of sliding frames that are hinged to the other ends of the two support arms at both ends, a pair of guide rods that are fixedly connected to both sides of the sliding frame, a pair of support plates three that are fixed to the bottom of the traction frame and allow the two guide rods to slide through, and a spring two that is sleeved on a guide rod and fixedly connected to the sliding frame and support plate three at both ends. The swing arms are longer than the support arms. The soil covering rods are located below the sliding frame and the guide rods. One end of the support arm extends into the interior of the sliding frame and is hinged to the inner wall of the sliding frame.

[0018] By adopting the above-mentioned soil covering mechanism, not only can the soil scooped up by the furrowing plow be effectively scraped and backfilled into the planting furrow, but the crank-slider structure formed by the combination of the swing arm, support arm and sliding frame can also work with the guide rod and spring to give the soil covering rod a certain degree of free up-and-down floating conditions, thereby flexibly adapting to different heights of field ridges.

[0019] A further configuration of the present invention is as follows: the sliding assembly includes an inclined plate fixedly connected to one side of two support plates at both ends, a transmission shaft three rotatably passing through the inclined plate, a pulley one and a sprocket three fixed to the transmission shaft three, a pulley two rotatably mounted on the inclined plate, a belt sleeved and mounted on pulley one and pulley two, a sprocket four fixed to the transmission part two, a chain two sleeved and mounted on sprocket three and sprocket four, a support seat fixed to the outer surface of the belt, a sliding column fixed to one side of the support seat, a transmission plate fixedly connected to the top of a movable plate, and an elongated hole opened on the transmission plate for the sliding column to slide; the transmission shaft three and the transmission part two are parallel to each other, and the axes of the transmission shaft three and the transmission part two are perpendicular to the inclined surface of the inclined plate respectively; the pulley one, pulley two and the belt are located on the upward side of the inclined plate, and the sprocket three, sprocket four and chain two are located on the downward side of the inclined plate; the transmission part two connected to the top of the spline part one rotatably passes through the protective cover two, and is simultaneously fixedly connected to the bevel gear four and the sprocket four.

[0020] By employing the aforementioned sliding assembly, when the drive shaft rotates, it drives the sprocket four to rotate. Then, the sprocket four, through the chain two and sprocket three, drives the drive shaft three to rotate. Subsequently, the pulley one on the drive shaft three drives the belt and pulley two to rotate and move respectively. Since the sliding column on the outer surface of the belt slides on the elongated hole in the drive plate, the sliding column will push or pull the drive plate linearly through the elongated hole under the movement of the belt. Furthermore, because the sliding column continuously rotates on both sides of pulley one or pulley two as it moves with the belt, the sliding column will also slide back and forth relative to the elongated hole, smoothly driving the moving plate connected to the drive plate to move back and forth linearly.

[0021] A further configuration of the present invention is as follows: the transmission plate includes a connecting part, a supporting part, and a transmission part, which are connected end to end from top to bottom. The connecting part is horizontally located at the top of the seed box and is fixedly connected to the movable plate. The supporting part is vertically located on one side of the seed box. The transmission part is parallel to the inclined plate and is located above the transmission part, with an elongated hole on the transmission part. A roller is rotatably provided on the side of the supporting part facing the seed box, and the roller rolls in contact with one side of the seed box.

[0022] By using the aforementioned transmission plate and roller, power can be transmitted stably, and the movement of the transmission plate on the outside of the seed box can be ensured to be stable.

[0023] A further configuration of the present invention is as follows: the rotating assembly includes a transmission shaft four that rotates through a movable plate and is located parallel to the top of the rotating cylinder; a spur gear one and a spur gear two fixed to the transmission shaft four and respectively located on both sides of the movable plate; a spur gear three fixed to the rotating cylinder and meshing with the spur gear two; and a rack fixed to the inner wall of the seed box and meshing with the spur gear one. The spur gear one and the rack are located on the side of the movable plate facing away from the other movable plate, and the rack is located above the spur gear one. The meshing transmission direction of the rack and the spur gear one is parallel to the moving direction of the movable plate. The spur gear two and the spur gear three are located on the side of the movable plate facing the other movable plate, and a protective cover three is fixedly provided on this side of the movable plate to protect the spur gear two and the spur gear three. The rotating cylinder and the transmission shaft four rotate through the protective cover three and are respectively connected to the spur gear three and the spur gear two.

[0024] By using the aforementioned rotating assembly, when the moving plate moves within the seed box, spur gear one will mesh with the rack and drive the transmission shaft four to rotate. Then, spur gear two on the transmission shaft four will rotate and mesh with spur gear three, causing spur gear three to drive the rotating cylinder to rotate, thereby achieving the effect of the stirring rod on the rotating cylinder moving while stirring.

[0025] A further feature of the present invention is that: a pair of rollers are rotatably provided on the two movable plates facing away from each other; two tracks are provided on the inner wall of the seed box to support the rolling of the two pairs of rollers; the rack is fixed to the bottom of one track; two baffles are fixedly provided on the top of the seed box to horizontally cover the two tracks; the movable plates are L-shaped, with the horizontal part of the movable plates moving above the baffles and the vertical part moving to one side of the baffles.

[0026] By using the aforementioned rollers and track, the movable plate can move stably inside the seed box; by using the aforementioned baffle and movable plate shape, the Pinellia ternata seed stems can be prevented from falling onto the track when the seed box is being filled.

[0027] The beneficial effects of this invention are:

[0028] 1. The rotating drum drives the stirring rod to rotate and reciprocate within the seed box, which not only continuously stirs and breaks up the Pinellia ternata seed stems, preventing them from sticking together due to moisture and ensuring smooth flow, thus avoiding blockage of the seed box and seed metering device and improving the continuity and reliability of sowing, but also the stirring rod can level the top of the seed stems in the seed box during its movement, making the seed stems evenly distributed. This is beneficial for the seed metering mechanism to quantitatively and at fixed intervals discharge the seed stems, improving the accuracy and uniformity of sowing.

[0029] 2. With an adjustable height ditching mechanism and an adaptive floating soil covering mechanism, it can flexibly cope with different field ridge heights and soil conditions, ensuring the quality of operations such as ditching, soil covering, and compaction. At the same time, the cage-like structure of the soil compaction roller effectively compacts the soil while avoiding slippage and soil adhesion, ensuring that it can still roll smoothly in wet fields.

[0030] 3. By adopting a splined drive shaft and drive cylinder, as well as a spring limiting structure, the power transmission stability of the seed metering mechanism and the soil pressing roller is ensured, and it is easy to disassemble and install quickly, making it convenient to inspect and replace vulnerable parts such as the seed metering mechanism and the soil pressing roller.

[0031] 4. By adopting a meshing transmission structure of spur gears and fixed racks, the rotating drum and stirring rod can be automatically driven to rotate when the moving plate moves, without the need for an additional power source. The structure is ingenious, energy-saving and efficient. Attached Figure Description

Detailed Implementation

[0040] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Example: A sowing device for planting Pinellia ternata, such as... Figure 1-4As shown, the system includes a towing frame 1, wheels 2 rotating at the front of the towing frame 1, a seed box 3 fixed to the top of the towing frame 1 for storing seeds, a seed dispensing mechanism 4 installed at the bottom of the seed box 3 for discharging seeds from the seed box 3 at fixed intervals and in fixed quantities, a furrowing mechanism 5 installed at the bottom of the towing frame 1 for creating seed furrows in the soil, a seed delivery pipe 6 connecting the seed dispensing mechanism 4 and the furrowing mechanism 5, a soil covering mechanism 7 installed at the bottom of the towing frame 1 for backfilling soil into the seed furrows to bury the seeds, a soil compaction roller 8 rotating at the rear of the towing frame 1 for rolling and compacting the soil, and a drive mechanism 9 for driving the seed dispensing mechanism 4 and the soil compaction roller 8. The seed box 3... The seed agitation and de-clumping mechanism 10 is provided inside. The seed agitation and de-clumping mechanism 10 includes a pair of vertically located moving plates 101 inside the seed box 3 and sliding inside the seed box 3, a sliding assembly 102 that drives the two moving plates 101 to slide linearly back and forth inside the seed box 3, a synchronization rod 103 that is horizontally located inside the seed box 3 and fixedly connected to one side of the two moving plates 101 at both ends, a rotating cylinder 104 that is rotatably sleeved on the synchronization rod 103, a plurality of stirring rods 105 that are uniformly arranged around the axis of the rotating cylinder 104 and fixedly connected at one end to the outer wall of the rotating cylinder 104, and a rotating assembly 106 that drives the rotating cylinder 104 to rotate relative to the synchronization rod 103.

[0042] By adopting the above technical solution, when the above device sows Pinellia ternata, the rotating mechanism in the seed stirring and unblocking mechanism 10 will drive the rotating cylinder 104 to rotate, so that the stirring rod 105 on the outer wall of the rotating cylinder 104 stirs the Pinellia ternata seed stems inside the seed box 3. At the same time, the moving component drives the moving plate 101 to move back and forth inside the seed box 3, so that the rotating cylinder 104 and the stirring rod 105 stir all the Pinellia ternata seed stems in the seed box 3 back and forth. This not only effectively prevents the Pinellia ternata seed stems from sticking together and clumping, so as to ensure that the Pinellia ternata seed stems flow smoothly into the seed dispensing mechanism 4, but also rakes and flattens the top of the Pinellia ternata seed stems in the seed box 3, so as to ensure that the Pinellia ternata seed stems in the seed box 3 flow evenly into each seed dispensing chamber 41 of the seed dispensing mechanism 4.

[0043] like Figure 4 As shown, the compaction roller 8 includes a pair of vertically parallel rolling discs 81, a pair of support shafts 82 respectively fixedly connected to opposite sides of the two rolling discs 81, and a plurality of rolling rods 83 uniformly surrounding the axis of the support shafts 82 and connected at both ends to the outer walls of the two support discs. A pair of vertical support plates 11 are fixedly installed at the bottom of the traction frame 1, and the two support shafts 82 are rotatably connected to the two support plates 11. The rolling discs 81 and the support shafts 82 are coaxial, and the distance between the center lines of the rolling rods 83 and the center lines of the support shafts 82 is not less than the radius of the rolling discs 81. By using the above-mentioned compaction roller 8, not only can the backfill soil be effectively compacted, but the cage-like structure formed by the rolling discs 81 and the rolling rods 83 can also prevent slippage and soil adhesion, ensuring that it can roll smoothly in the field.

[0044] like Figure 2-4 As shown, the seed metering mechanism 4 includes multiple seed metering chambers 41 spaced apart at the bottom of the seed box 3 and connected to the inside of the seed box 3; multiple seed metering wheels 42 rotatably disposed in each seed metering chamber 41; multiple seed metering grooves 43 evenly distributed on the outer wall of the seed metering wheels 42; and a rotating shaft 44 that rotatably passes through all the seed metering chambers 41 and connects to the seed metering wheels 42 inside them. Each seed metering chamber 41 includes a feeding chamber 411 and a discharging chamber 412, with the top of the seed metering wheel 42 located in the feeding chamber 411 and the bottom of the seed metering wheel 42 located in the discharging chamber 412. The width of the feeding chamber 411 and the width of the discharging chamber 411 are as follows: The width of the seed metering wheel 42 and the radius of the seed metering wheel 42 decrease sequentially, and the width of the discharge chamber 412 is close to the radius of the seed metering wheel 42. The bottom of the discharge chamber 412 is open and connected to the seed delivery pipe 6. The rotating shaft 44 and the seed metering wheel 42 are coaxial. The driving mechanism 9 drives the rotating shaft 44 and the support shaft 82 to rotate. A pair of vertical support plates 12 are fixedly installed on the top of the traction frame 1, and the two ends of the rotating shaft 44 are respectively rotatably connected to the two support plates 12. The seed box 3 is located in the middle of the two support plates 12, and the two ends are respectively fixedly connected to the two support plates 12 facing each other.

[0045] By employing the aforementioned seed metering mechanism 4, when quantitative seed metering is required, the drive mechanism 9 will drive the rotating shaft 44 to rotate, causing the rotating shaft 44 to drive the seed metering wheels 42 in all seed metering chambers 41 to rotate. Since the radius of the seed metering wheel 42 is smaller than the width of the feeding chamber 411 and close to the width of the discharging chamber 412, before the seed metering wheel 42 rotates, the Pinellia ternata seed stems falling from the seed box 3 into the feeding chamber 411 cannot directly pass through the narrow gap between the side of the seed metering wheel 42 and the inner wall of the discharging chamber 412 to enter the interior of the discharging chamber 412. However, during the rotation of the seed metering wheel 42, a single or a small number of Pinellia ternata seed stems in the feeding chamber 411 can fall into the seed metering groove 43 on the outer wall of the seed metering wheel 42 and follow the seed metering wheel 42 to enter the discharging chamber 412 in sequence, thereby achieving the effect of quantitative seed metering.

[0046] like Figure 3 , Figure 5As shown, the ditching mechanism 5 includes multiple ditching plows 51 arranged at intervals, multiple seed-spreading tubes 52 respectively fixedly connected to the ditching plows 51, multiple square tubes 53 respectively fixedly supporting the seed-spreading tubes 52, and fasteners 54 vertically fastening the square tubes 53 to the traction frame. The ditching plows 51 are located below the square tubes 53, and the seed-spreading tubes 52 are fixed to one side of the square tubes 53. The top opening of the seed-spreading tubes 52 is connected to the seed delivery tube 6, and the bottom outlet of the seed-spreading tubes 52 is located in the middle of the concave surface of the ditching plows 51. The fasteners 54 include a U-shaped plate 541, a pair of U-bolts 542U, and two pairs of fastening nuts 543. The U-shaped plate 541 holds the square tubes 53, and the two U-bolts 542U together hold the crossbeam of the traction frame 1 and are located on both sides of the square tubes 53. The two external threads of the U-bolts 542U pass through the edge of the U-shaped plate 541 and are respectively threaded to the fastening nuts 543. By adopting the above-mentioned ditching mechanism 5, it is not only possible to effectively dig planting furrows in the field for pre-buried Pinellia ternata seedlings, but also, in conjunction with the fasteners 54 that connect and fix the square tube 53 on the traction frame 1, it is convenient for the user to adjust the height of the ditching plow head 51 to adapt to different planting furrow depths.

[0047] like Figure 2-4 As shown, the drive mechanism 9 includes a motor 91 fixed to the traction frame 1, a sprocket 92 fixedly connected to the output end of the motor 91, a sprocket 93 fixedly connected to the rotating shaft 44, a chain 94 mounted on the sprocket 92 and the sprocket 93, a pair of coaxial drive shafts 95 and 96 respectively rotatably mounted on one side of the support plate 11 and the support plate 22, a pair of bevel gears 97 and 98 respectively fixedly connected to the support shaft 82 and the rotating shaft 44, a pair of bevel gears 99 and 9a respectively fixedly connected to the drive shaft 95 and the drive shaft 296 and respectively meshing with the bevel gears 97 and 98, a drive cylinder 9b slidably sleeved on the drive shaft 95 and the drive shaft 296, a limiting ring 9c fixed inside the drive cylinder 9b, and a spring 9d fixedly connected at both ends to the drive shaft 296 and the limiting ring 9c respectively.

[0048] The first transmission shaft 95 includes a spline portion 951 and a pair of transmission portions 952 respectively connected to the two ends of the spline portion 951. The second transmission shaft 96 includes a spline portion 961 and a pair of transmission portions 962 respectively connected to the two ends of the spline portion 961. The inner wall of the transmission cylinder 9b is provided with spline grooves 9b1 and 9b2 respectively fitted to the spline portion 951 and the spline portion 961. The limiting ring 9c is located between the spline groove 9b1 and the spline groove 9b2. The first spring 9d is sleeved on the transmission portion 962, and the two ends of the first spring 9d are respectively connected to the spline portion 951 and the limiting ring 9c. The inner diameter of the limiting ring 9c and the outer diameter of the first transmission portion 952 and the second transmission portion 962 are equal, and the ends of the first transmission portion 952 and the second transmission portion 962 slide into the limiting ring 9c.

[0049] A protective cover 111 is fixedly installed on one side of the support plate 11 to protect bevel gear 97 and bevel gear 99. The support shaft 82 and the transmission part 952 rotate through the protective cover 111 and are respectively connected to bevel gear 97 and bevel gear 99. A protective cover 121 is fixedly installed on one side of the support plate 12 to protect bevel gear 98 and bevel gear 9a. The rotating shaft 44 and the transmission part 962 rotate through the protective cover 121 and are respectively connected to bevel gear 98 and bevel gear 9a.

[0050] By employing the aforementioned drive mechanism 9, when it is necessary to drive the rotating shaft 44 and the support shaft 82 to rotate, the motor 91 first drives the sprocket 1 92 to rotate, so that the sprocket 1 92 drives the rotating shaft 44 to rotate through the chain 1 94 and the sprocket 2 93. Then, the rotating shaft 44 drives the bevel gear 2 98 to rotate and mesh with the bevel gear 4 9a, so that the bevel gear 4 9a drives the transmission shaft 2 96 to rotate. Since the spline part 1 951 of the transmission shaft 1 95 and the spline part 2 961 of the transmission shaft 2 96 are respectively engaged with the spline groove 1 9b1 and the spline groove 2 9b2 inside the transmission cylinder 9b, the transmission cylinder 9b and the transmission shaft 2 96 will rotate synchronously with the transmission shaft 1 95. Finally, the transmission shaft 1 95 drives the bevel gear 3 99 to rotate and mesh with the bevel gear 1 97, so that the bevel gear 1 97 drives the support shaft 82 to rotate, thereby realizing the synchronous operation of the soil pressing roller 8 and the seed metering mechanism 4. The transmission connection structure of drive shaft 1 95, drive shaft 2 96, and drive cylinder 9b not only transmits power stably but also adapts to various field environments, making manual maintenance and cleaning easy and convenient. The spring 1 9d and limit ring 9c inside the drive cylinder 9b allow users to quickly disassemble and assemble the above-mentioned transmission structure (disassembly method: manually lift the drive cylinder 9b upwards to disconnect the drive cylinder 9b and drive shaft 2 96; installation is the opposite), to disconnect and connect the transmission of drive shaft 1 95 and drive shaft 2 96, thereby facilitating the maintenance and repair of easily worn parts such as the seed metering mechanism 4 or the soil pressing roller 8. Protective covers 111 and 121 not only prevent soil impurities from contaminating and wearing the spur gears, thus protecting the meshing transmission safety of the spur gears, but also support the stable rotation of drive shaft 1 95 and drive shaft 2 96.

[0051] like Figure 3 As shown, the soil covering mechanism 7 includes a pair of swing arms 71 that are hinged to the bottom of the traction frame 1 at one end, a soil covering rod 72 that is fixedly connected to the other ends of the two swing arms 71 at both ends, a pair of support arms 73 that are hinged to the other ends of the two swing arms 73 at one end, a pair of sliding frames 74 that are hinged to the other ends of the two support arms 73 at both ends, a pair of guide rods 75 that are fixedly connected to both sides of the sliding frame 74, a pair of support plates 76 that are fixed to the bottom of the traction frame 1 and allow the two guide rods 75 to slide through, and a spring 77 that is sleeved on a guide rod 75 and fixedly connected to the sliding frame 74 and the support plate 76 at both ends. The swing arms 71 are longer than the support arms 73. The soil covering rods 72 are located below the sliding frame 74 and the guide rods 75. One end of the support arm 73 extends into the sliding frame 74 and is hinged to the inner wall of the sliding frame 74. By adopting the above-mentioned soil covering mechanism 7, not only can the soil scooped up by the furrowing plow head 51 be effectively scraped and backfilled into the planting furrow, but the crank-slider structure formed by the combination of the swing arm 71, the support arm 73 and the sliding frame 74 can also work with the guide rod 75 and the spring 77 to give the soil covering rod 72 a certain degree of free up-and-down floating conditions, thereby flexibly adapting to different heights of field ridges.

[0052] like Figure 3 , Figure 4 As shown, the sliding assembly 102 includes an inclined plate 102a fixedly connected to one side of two support plates 12 at both ends, a transmission shaft 102b rotatably passing through the inclined plate 102a, a pulley 102c and a sprocket 102d fixed to the transmission shaft 102b, a pulley 102e rotatably mounted on the inclined plate 102a, a belt 102f sleeved and mounted on the pulleys 102c and 102e, a sprocket 102g fixed to the transmission part 962, a chain 102h sleeved and mounted on the sprockets 102d and 102g, a support base 102i fixed to the outer surface of the belt 102f, a sliding column 102k fixed to one side of the support base 102i, and a movable plate fixedly connected. The transmission plate 102m at the top of 101 has an elongated hole 102n on the transmission plate 102m for sliding of the sliding column 102k; the transmission shaft 102b and the transmission part 962 are parallel to each other, and the axes of the transmission shaft 102b and the transmission part 962 are perpendicular to the inclined plane of the inclined plate 102a respectively; the pulley 102c, the pulley 102e and the belt 102f are located on the upward side of the inclined plate 102a; the sprocket 102d, the sprocket 102g and the chain 102h are located on the downward side of the inclined plate 102a; the transmission part 962 connected to the top of the spline part 951 rotates through the protective cover 121 and is simultaneously fixedly connected to the bevel gear 9a and the sprocket 102g.

[0053] By employing the aforementioned sliding assembly 102, when the drive shaft 95 rotates, it drives the sprocket 102g to rotate. Then, the sprocket 102g, through the chain 102h and sprocket 102d, drives the drive shaft 102b to rotate. Subsequently, the pulley 102c on the drive shaft 102b drives the belt 102f and pulley 102e to rotate and move respectively. Because the sliding post 102k on the outer surface of the belt 102f slides on the transmission plate 102m... The elongated hole 102n allows the slide column 102k to push or pull the transmission plate 102m in a linear motion under the movement of the belt 102f. As the slide column 102k moves with the belt 102f, it continuously rotates on both sides of the pulley 102c or pulley 102e. Therefore, the slide column 102k will also slide back and forth with the elongated hole 102n, and smoothly drive the moving plate 101 connected to the transmission plate 102m to move back and forth in a linear motion.

[0054] like Figure 3 , Figure 4As shown, the transmission plate 102m includes a connecting part, a supporting part, and a transmission part, which are connected end-to-end from top to bottom. The connecting part is horizontally located at the top of the seed box 3 and is fixedly connected to the moving plate 101. The supporting part is vertically located on one side of the seed box 3. The transmission part is parallel to the inclined plate 102a, and the elongated hole 102n is located on the transmission part. A roller 102o is rotatably provided on the side of the supporting part facing the seed box 3, and the roller 102o rolls in contact with one side of the seed box 3. By using the above-mentioned transmission plate 102m and roller 102o, power can be stably transmitted, and the movement of the transmission plate 102m outside the seed box 3 can be ensured.

[0055] like Figure 3 , Figure 6 As shown, the rotating assembly 106 includes a drive shaft 106a that rotates through a moving plate 101 and is parallel to and located above the rotating cylinder 104; spur gears 106b and 106c fixed to the drive shaft 106a and located on opposite sides of the moving plate 101; a spur gear 106d fixed to the rotating cylinder 104 and meshing with spur gear 106c; and a rack 106e fixed to the inner wall of the seed box 3 and meshing with spur gear 106b. The spur gears 106b and rack 106e are located on the side of the moving plate 101 facing away from the other moving plate 101, and the rack 106e... 06e is located above spur gear 106b; the meshing transmission direction of rack 106e and spur gear 106b is parallel to the moving direction of moving plate 101; spur gear 2 106c and spur gear 3 106d are located on the side of moving plate 101 facing another moving plate 101, and a protective cover 3 101a is fixedly provided on this side of moving plate 101 to protect spur gear 2 106c and spur gear 3 106d; the rotating cylinder 104 and the transmission shaft 4 106a rotate through the protective cover 3 101a and are respectively connected to spur gear 3 106d and spur gear 2 106c. By employing the aforementioned rotating assembly 106, when the moving plate 101 moves within the seed box 3, the first spur gear 106b meshes with the rack 106e, driving the fourth transmission shaft 106a to rotate. Then, the second spur gear 106c on the fourth transmission shaft 106a rotates and meshes with the third spur gear 106d, causing the third spur gear 106d to drive the rotating cylinder 104 to rotate, thereby achieving the effect of the stirring rod 105 on the rotating cylinder 104 moving while stirring.

[0056] like Figure 2 , Figure 6As shown, each of the two movable plates 101 is rotatably equipped with a pair of rollers 101b on opposite sides. The inner wall of the seed box 3 is provided with two tracks 31 that support the rolling of the two pairs of rollers 101b. The rack 106e is fixed to the bottom of one track 31. Two baffles 32 are fixedly installed on the top of the seed box 3, horizontally covering the two tracks 31 respectively. The movable plates 101 are L-shaped, with the horizontal portion moving above the baffles 32 and the vertical portion moving to one side of the baffles 32. By using the rollers 101b and tracks 31, stable movement of the movable plates 101 within the seed box 3 can be achieved. The shape of the baffles 32 and the movable plates 101 prevents the Pinellia ternata seeds from falling onto the tracks 31 during loading.
