Different medicinal materials have different requirements for climate and soil. When planting Chinese medicinal materials, it is necessary to ridge the planting land. Ridging can reduce soil bulk density, enhance soil permeability, facilitate drainage and irrigation, and promote the extension of medicinal material roots and the growth of the above-ground parts of medicinal plant plants. Therefore, the quality of ridge building is highly correlated with the yield and quality of medicinal materials.

[0016] The beneficial effects are: 1. The present invention can transport the scooped soil by arranging a conveyor belt behind the bucket, and screen the soil through the part composed of round bars in the middle of the conveyor belt. The loose soil will fall back to the ground from the gaps between the round bars, and some larger debris in the soil, such as stones, will continue to be transported with the conveyor belt. During the continuous conveying process of the conveyor belt, the soil on both sides of the conveyor belt surface and some larger stones will be transported to the diversion frame, and slide into the guide pipe through the inclined surface at the bottom of the diversion frame, and then be discharged from the guide pipe to the positions on both sides of the ridge forming area, so as to avoid the situation that the soil in the place with stones is difficult to be compacted evenly during ridge forming, resulting in a large difference in looseness and compactness, which will affect the growth of crop roots, make the roots grow unevenly in soils with different compactness, and affect the root system's absorption of water and nutrients.

[0017] 2. The present invention connects the ridging roller to the towing frame, so that the traction vehicle will drive the ridging roller to move during the traction process. When moving, the ridging roller continuously rolls to form ridging. Through the weight of the ridging roller itself, the soil pile formed by the soil falling from the middle round bar position of the conveyor belt is compacted and flattened to form a trapezoidal ridge platform. Planting on the ridge platform makes the planting surface higher than the surrounding ground. During rainfall or irrigation, excess water can be drained away from the ridge more quickly to avoid waterlogging in the soil. This is crucial for crops that are not resistant to waterlogging, and can effectively reduce the probability of root rot and disease caused by waterlogging. At the same time, good drainage performance also helps to maintain soil aeration, creating favorable conditions for root growth and breathing.

[0018] 3. The present invention connects a rotatable film coating roller behind the ridging roller through an articulated rod, so that when the ridging roller moves to form ridges, the film coating roller will move along with it, so that after the ridging roller completes ridging, the film coating roller will roll on the ridge platform following the ridging roller, and during the rolling of the film coating roller, the ground film wound on the surface of the film coating roller will be unfolded and laid on the surface of the ridge platform, and because the film coating roller is located in front of the discharge port of the guide tube, the soil and stones discharged from the guide tube can just fall on both sides of the ground film laid on the ridge platform, fixing the ground film and preventing the ground film from shifting and losing its effect. By laying the ground film on the surface of the ridge platform, the evaporation of soil moisture can be reduced, and the soil moisture can be kept relatively stable. Stable soil moisture is conducive to seed germination and seedling growth, and improves the emergence rate and survival rate of crops. The ground film covers the soil surface to form a physical barrier, which blocks the sunlight and makes it difficult for weed seeds to germinate.

[0019] Fourth, the present invention arranges a tail frame connected to a rotatable and rolling seeding roller, so that the seeding roller can follow the traction and roll on the ridge platform where the ground film is laid, and the seeding roller realizes intermittent seeding during the continuous rolling process, which can greatly improve the planting efficiency and reduce the investment in labor costs, and large-scale planting has higher economic benefits.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0024] See also Figure 1 - Fig. 9As shown, the present invention provides a ridge-forming device for a Chinese medicinal material planting site, comprising a traction frame 1 for connecting a traction carrier, a support frame 2 being fixedly connected to the bottom of the traction frame 1, a separation mechanism being arranged inside the support frame 2 for stripping off some larger lumps in the soil, a ridge-forming mechanism being arranged behind the support frame 2 for forming ridges in the field, a film-covering mechanism being arranged behind the ridge-forming mechanism for film-covering the ridge platform, a sowing mechanism being arranged behind the film-covering mechanism for sowing medicinal material seeds, wherein the separation mechanism comprises a bucket 3, the bucket 3 being fixedly connected to the lower side of the front side of the support frame 2, and the bucket 3 being inserted into the soil to turn the soil during the traction process of the traction carrier, so that the organic matter in the surface layer is turned into the deep layer of the soil, and at the same time, the deep layer of the soil is turned over. To the surface, the contact area between organic matter and soil microorganisms is increased, so that the microorganisms in the soil can accelerate the decomposition of organic matter and convert it into nutrients that can be absorbed and utilized by plants, such as nitrogen, phosphorus, potassium, etc. The support frame 2 is fixedly connected to the support plates 4 on both sides of the rear of the bucket 3, and a conveyor belt 5 is arranged between the two support plates 4. Two transmission rollers 6 for transmission arranged inside the conveyor belt 5 are rotatably connected to the support plates 4. Both sides of the outer walls of the two transmission rollers 6 are fixedly sleeved with first synchronous wheels 7, and the two first synchronous wheels 7 on the same side are connected by transmission through the first synchronous belt 8. The middle part of the conveyor belt 5 is composed of round bars 9 arranged at intervals. By arranging the conveyor belt 5 behind the bucket 3, the shoveled The soil is transported and screened by the part composed of the round bars 9 in the middle of the conveyor belt 5. The loose soil will fall back to the ground from the gaps between the round bars 9. Some larger debris in the soil, such as stones, will continue to be transported with the conveyor belt 5. The support frame 2 is fixedly connected to a diverter frame 10 at the rear of the conveyor belt 5. Guide pipes 11 are fixedly connected to both sides of the diverter frame 10. When the conveyor belt 5 continues to transport, the soil on both sides of the surface of the conveyor belt 5 and some larger stones are transported to the diverter frame 10, and slide into the guide pipe 11 through the inclined surface at the bottom of the diverter frame 10, and then discharged from the guide pipe 11 to the positions on both sides of the ridge forming area, so as to avoid the soil in the place with stones being difficult to be evenly compacted during ridge forming. , there is a large difference in looseness and compactness, which will affect the growth of crop roots, causing the roots to grow unevenly in soils of different compactness, affecting the root system's absorption of water and nutrients. The separation mechanism also includes a servo motor 12, which is fixedly connected to one side of the support frame 2. The servo motor 12 drives the transmission roller 6 at the top of the conveyor belt 5 to rotate through a reducer 13. By setting the reducer 13, the torque during transmission can be increased to increase the load capacity during driving. During actual driving, the servo motor 12 drives one of the transmission rollers 6 to rotate, causing the first synchronous wheel 7 mounted on the outer wall to rotate, and drives the other transmission roller 6 to rotate together through the first synchronous belt 8, thereby driving the conveyor belt 5 to transport.

[0025] In this embodiment, please refer to Figure 1 , Figure 2 The separation mechanism also includes a tilling roller 14, which is rotatably connected to the inner wall of the support frame 2 in front of the bucket 3. Before the bucket 3 shovels the soil, the soil on the ground can be cut by the rotation of the tilling roller 14, so that the soil is looser and the size of the soil blocks is more uniform, which is more conducive to the penetration of water and nutrients and can promote the growth of the root system. In addition, crushing the soil in advance can also reduce the resistance of the bucket 3 when shoveling the soil, so that the bucket 3 can operate more smoothly. The two ends of the tilling roller 14 are located at the lower position of the conveyor belt 5. The two ends of the transmission roller 6 are fixedly connected with the second synchronous wheel 15, and the two second synchronous wheels 15 on the same side are connected by the second synchronous belt 16. By arranging the second synchronous wheels 15 at both ends of the transmission roller 6, when the transmission roller 6 rotates, one of the second synchronous wheels 15 will be driven to rotate, and the other second synchronous wheel 15 at both ends of the tilling roller 14 will be driven to rotate by the second synchronous belt 16, so that the tilling roller 14 starts to rotate and crushes the soil in front of the bucket 3.

[0026] For further information, see Figure 4 The ridging mechanism includes two groups of trailers 17, which are fixedly connected to both sides of the support frame 2 respectively. A ridging roller 18 is rotatably connected to the position between the two groups of trailers 17. The middle area of ​​the ridging roller 18 is concave. The ridging roller 18 is connected to the trailer 17, so that the traction vehicle will drive the ridging roller 18 to move during the traction process. When moving, the ridging roller 18 continuously rolls to form ridging, and the weight of the ridging roller 18 itself compacts and flattens the soil pile formed by the soil screened and fallen at the position of the middle round rod 9 of the conveyor belt 5 to form a trapezoidal ridge platform.

[0027] For further information, see Figure 5 The two groups of trailers 17 are fixedly connected with a support frame 19 at the top near one end of the ridging roller 18, and a baffle 20 is fixedly connected to the position between the two groups of support frames 19, and the baffle 20 fits the concave area on the top of the ridging roller 18. By arranging a support frame 19 connected to the baffle 20 on the top of the ridging roller 18, the conveyor belt 5 can be intercepted to screen the soil, so as to avoid directly crossing the ridging roller 18 due to inertia when falling, and falling behind the ridging roller 18 to complete the ridging platform, which affects the flatness of the ridging platform and is not conducive to the subsequent film covering work, and the support frame 19 and the baffle 20 can scrape off the soil adhered to the surface of the ridging roller 18 during the rotation of the ridging roller 18, so as to avoid excessive soil adhering to the surface of the ridging roller 18 affecting the ridging.

[0028] Also, see Figure 6The film covering mechanism includes two hinged rods 21, and the two hinged rods 21 are respectively hinged at one end of the two groups of trailers 17 close to the ridging roller 18, and a film covering roller 22 is rotatably connected between the two hinged rods 21. The rotatable film covering roller 22 is connected to the rear of the ridging roller 18 through the hinged rod 21, so that when the ridging roller 18 moves to form ridges, the film covering roller 22 will move together, so that after the ridging roller 18 completes ridge forming, the film covering roller 22 will follow the ridging roller 18 to roll on the ridge platform, and during the rolling of the film covering roller 22, the ground film wound on the surface of the film covering roller 22 will be unfolded and laid on the surface of the ridge platform, and because the film covering roller 22 is located in front of the discharge port of the guide pipe 11, the soil and stones discharged from the guide pipe 11 can just fall on both sides of the ground film laid on the ridge platform, fix the ground film, and prevent the ground film from displacement and losing its effect.

[0029] In addition, see Figure 6 , Figure 7 The two hinged rods 21 are at the top of one end of the coating roller 22 and are respectively hinged with elastic telescopic rods 23, and the end of the elastic telescopic rod 23 away from the hinged rod 21 is hinged to the outer wall of the guide tube 11. Through the action of the tension of the elastic telescopic rod 23, the coating roller 22 is always in contact with the ridge platform, avoiding excessive gap between the coating roller and the ridge platform during coating, which affects the laying of the ground film and causes waste of the ground film.

[0030] It is worth noting that see Figure 1 , Figure 8 , Fig. 9The sowing mechanism includes a tail frame 24, which is fixedly connected to the back of the baffle 20, and the bottoms of both sides of the tail frame 24 are respectively fixedly connected with elastic telescopic frames 25, and a sowing roller 26 is rotatably connected between the two sets of elastic telescopic frames 25. A cavity for placing seeds is provided inside the sowing roller 26, and a certain pressure is always maintained between the sowing roller 26 and the ridge platform through the tension of the elastic telescopic frame 25. The positions on both sides of the top of the inner wall of the sowing roller 26 are fixedly connected with hanging rods 27, and the bottom of the hanging rod 27 is fixedly connected with an air cylinder 28, and the inner wall of the air cylinder 28 A piston 29 is slidably connected, a sowing tube 30 is fixedly connected to the bottom of the piston 29, a notch 31 is provided on the wall of the sowing tube 30, an arc-shaped pressing knife 32 is fixedly connected to the bottom of the sowing tube 30 for cutting the mulch film to facilitate sowing, a push rod 33 is slidably connected to the inner wall of the piston 29, and the push rod 33 extends to the inside of the sowing tube 30, a return spring 34 is fixedly connected to the position between the top of the piston 29 and the inner wall of the air cylinder 28, and the sowing roller 26 that can rotate and roll is connected by setting the tail frame 24, so that the sowing roller 26 can follow the ridge pulled on the mulch film. During the rolling process of the seeding roller 26, each time the arc-shaped pressing knife 32 protruding from the surface of the seeding roller 26 contacts the ground film, an opening for seeding will be cut on the ground film, and the arc-shaped pressing knife 32 will also be squeezed due to the contact with the ridge platform, so that the seeding tube 30 will retract into the inside of the seeding roller 26, so that the notch 31 on the outer wall of the seeding tube 30 is exposed in the seeding roller 26, so that the seeds at the bottom of the seeding roller 26 will automatically roll into the seeding tube 30 from the notch 31, and the retracted seeding tube 30 will push the piston 29 to slide on the air cylinder 28 and squeeze the air inside the air cylinder 28. The air is pressed in the air cylinder 28, so that the pressure inside the air cylinder 28 pushes the push rod 33 to slide in the sowing tube 30, squeezes out the seeds in the sowing tube 30, and presses the seeds into the soil where the curved pressing knife 32 cuts the mulch film. Subsequently, when the curved pressing knife 32 rolls away from the ridge platform due to the sowing roller 26, the tension of the return spring 34 in the air cylinder 28 pushes the piston 29 to reset, so that the sowing tube 30 connected with the curved pressing knife 32 and the push rod 33 are reset together, so that during the rolling process of the sowing roller 26, the curved pressing knife 32 will sow once each time it contacts the ridge platform, so as to achieve the purpose of intermittent sowing.

[0031] How it works When in use, the traction frame 1 is connected to the tail of the traction vehicle for traction. During the traction process, the bucket 3 of the traction vehicle will be inserted into the soil to turn the soil, and the servo motor 12 will drive one of the transmission rollers 6 to rotate, so that the first synchronous wheel 7 set on the outer wall rotates, and the other transmission roller 6 is driven to rotate together through the first synchronous belt 8, thereby driving the conveyor belt 5 for transportation. The scooped soil can be transported and the soil can be screened through the part composed of the round rods 9 in the middle of the conveyor belt 5. The loose soil will fall back to the ground from the gaps between the round rods 9, and some larger debris in the soil, such as stones, will continue to be transported with the conveyor belt 5. In the process of continued transportation of the conveyor belt 5, the soil on both sides of the surface of the conveyor belt 5 will be mixed with some smaller debris. The large stones are transported to the diverter frame 10, and slide into the guide pipe 11 through the inclined surface at the bottom of the diverter frame 10, and then discharged from the guide pipe 11 to the positions on both sides of the ridge forming area, so as to avoid the situation that the soil in the place with stones is difficult to be compacted evenly during ridge forming, and there is a large difference in looseness and compactness. In addition, by arranging the second synchronous wheels 15 at both ends of the transmission roller 6, when the transmission roller 6 rotates, it will drive one of the second synchronous wheels 15 to rotate, and drive the other second synchronous wheels 15 at both ends of the tilling roller 14 to rotate through the second synchronous belt 16, so that the tilling roller 14 starts to rotate and breaks the soil in front of the bucket 3, so that before the bucket 3 shovels the soil, the soil on the ground can be cut by the rotation of the tilling roller 14, making the soil looser and the soil clods more. The size is more uniform, which is more conducive to the penetration of water and nutrients, and can promote the growth of the root system. In addition, breaking the soil in advance can also reduce the resistance of the bucket 3 when shoveling soil, so that the bucket 3 can operate more smoothly. The traction carrier is connected to the ridging roller 18 by the trailer 17, so that the ridging roller 18 can be driven to move together during the traction process. When moving, the ridging roller 18 continuously rolls to form ridging. Through the weight of the ridging roller 18 itself, the soil pile formed by the soil screened and fallen at the position of the middle round rod 9 of the conveyor belt 5 is compacted and flattened to form a trapezoidal ridge platform. In addition, by arranging a support frame 19 connected to the baffle 20 at the top of the ridging roller 18, the soil screened by the conveyor belt 5 can be intercepted to avoid directly crossing the ridging roller due to inertia when falling. 18, falls behind the ridging roller 18 to complete the ridging platform, affecting the flatness of the ridging platform and being unfavorable to the subsequent film covering work, and the support frame 19 and the baffle plate 20 can scrape off the soil adhered to the surface of the ridging roller 18 during the rotation of the ridging roller 18 to avoid excessive soil adhering to the surface of the ridging roller 18 affecting the ridging, and a rotatable film covering roller 22 is connected to the rear of the ridging roller 18 through an articulated rod 21, so that when the ridging roller 18 moves to ridge, the film covering roller 22 will move along, so that after the ridging roller 18 completes the ridging, the film covering roller 22 will follow the ridging roller 18 to roll on the ridge platform, and during the rolling of the film covering roller 22, the ground film wound on the surface of the film covering roller 22 will be unfolded and laid on the surface of the ridge platform, and because the film covering roller 22 is located in front of the discharge port of the guide tube 11,The soil and stones discharged from the guide tube 11 can just fall on both sides of the ground film laid on the ridge, fix the ground film, avoid displacement of the ground film and lose its effect, and connect the rotatable seeding roller 26 with the tail frame 24, so that the seeding roller 26 can follow the traction and roll on the ridge where the ground film is laid. During the rolling process of the seeding roller 26, each time the arc-shaped pressing knife 32 protruding from the surface of the seeding roller 26 contacts the ground film, an opening for sowing will be cut on the ground film, and the arc-shaped pressing knife 32 will also be squeezed due to the contact with the ridge, so that the seeding tube 30 will retract into the inside of the seeding roller 26, so that the notch 31 on the outer wall of the seeding tube 30 is exposed in the seeding roller 26, so that the seeds at the bottom of the seeding roller 26 will be The seeds will automatically roll into the sowing tube 30 from the gap 31, and the retracted sowing tube 30 will push the piston 29 to slide in the air cylinder 28 and squeeze the air inside the air cylinder 28, so that the pressure inside the air cylinder 28 pushes the push rod 33 to slide in the sowing tube 30, squeezes out the seeds in the sowing tube 30, and presses the seeds into the soil where the arc-shaped pressing knife 32 cuts the mulch film. When the arc-shaped pressing knife 32 rolls away from the ridge platform due to the sowing roller 26, the tension of the return spring 34 in the air cylinder 28 will push the piston 29 to reset, so that the sowing tube 30 connected with the arc-shaped pressing knife 32 and the push rod 33 will be reset together, so that during the rolling process of the sowing roller 26, each time the arc-shaped pressing knife 32 contacts the ridge platform, it will sow once, so as to achieve the purpose of intermittent sowing.
