Description

Technical Field

[0001] This invention relates to the technical field of seeders, and in particular to a cotton and fennel seeder. Background Technology

[0002] Cotton is a plant belonging to the genus *Gossypium* in the family Malvaceae, including upland cotton, herbaceous cotton, and tree cotton. It is an annual herbaceous or subshrubby plant with sparsely covered long, soft hairs on its twigs; the seeds are separate, oval, and covered with long white cottony hairs and short, grayish-white, non-removable cottony hairs. Cotton production and cultivation techniques have undergone a long development process of approximately 2000 years, and it is now widely cultivated in cotton-producing areas throughout China. Cotton is an important economic crop in my country. It also has medicinal properties; being mild in nature, it can be used as an adjunct treatment for bleeding symptoms. Processed cotton can also be used as medical absorbent cotton.

[0003] Fennel is an herbaceous plant belonging to the genus Fennel in the family Apiaceae. It has the functions of dispelling cold and relieving pain, regulating qi and stomach. It flowers in early summer, and the fruit consists of 8-9 woody follicles, whorled in a star-shaped pattern. It has a strong aroma and can be used as a spice, condiment, and for medicinal purposes. Its dried fruit of the same name is one of the seasonings in Chinese cuisine and Southeast Asian cooking, which has significantly increased its economic benefits.

[0004] The cotton-fennel intercropping model is an ecologically efficient agricultural planting technique. Through reasonable layout and scientific management, it ensures both high and stable cotton yields while increasing fennel production. Specifically, four rows of fennel are intercropped between six rows of cotton, improving planting efficiency, reducing labor costs, and guaranteeing planting quality. Fennel's shallow root system allows it to form a three-dimensional nutrient absorption structure with the deep root system of cotton. Furthermore, fennel's entire growth period is approximately 90 days, resulting in a short symbiotic period with cotton and fewer conflicts with sunlight, water, and fertilizer requirements. Compared to planting cotton alone, this intercropping model not only improves land utilization but also increases the income of workers and the local population.

[0005] Currently, in order to increase crop yields and income, farmers often intercrop fennel between cotton plants. However, traditional cotton planters can only plant cotton and cannot plant fennel at the same time. This requires manual replanting of fennel after cotton is planted, which makes the labor intensity of farmers high, the process cumbersome, and the planting efficiency low. Summary of the Invention

[0006] The purpose of this invention is to provide a cotton and fennel co-sowing machine to solve the problems existing in the prior art, enabling cotton and fennel to be sown at the same time, reducing manual labor intensity and improving sowing efficiency.

[0039] The purpose of this invention is to provide a cotton and fennel co-sowing machine to solve the problems existing in the prior art, enabling cotton and fennel to be sown at the same time, reducing the intensity of manual labor and improving sowing efficiency.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] like Figures 1 to 13 As shown, this embodiment provides a cotton-fennel simultaneous sowing machine, including a frame 1, a cotton sowing unit, and a fennel sowing unit. The frame 1 is equipped with both the cotton and fennel sowing units. Several cotton sowing units 13 are arranged side-by-side in the cotton sowing unit, and a fennel sowing unit 17 is positioned between every four cotton sowing units (i.e., the cotton sowing units 13 are located in the middle of the wide row spacing of the fennel sowing units 17). The cotton sowing units 13 are used to sow cotton, and the fennel sowing units 17 are used to sow fennel. This embodiment, by simultaneously installing the cotton and fennel sowing units, enables the simultaneous sowing of cotton and fennel, reducing manual labor intensity and improving sowing efficiency.

[0043] As an optional solution, in this embodiment, the fennel planter 17 includes a seed storage box 16, a planting box, and a fixing frame assembly. One end of the fixing frame assembly is detachably connected to the frame 1, and the other end is rotatably connected to the planting box. The seed storage box 16 is connected to the planting box, and several seed outlet assemblies are evenly distributed around the circumference of the planting box. A duckbill seed outlet assembly 26 is provided on the outer side of the seed outlet assembly, and a seed picker 30 is provided on the inner wall of the planting box. The seed picker 30 is provided one-to-one with the seed outlet assembly, and the seeds scooped by the seed picker 30 are poured into the seed outlet assembly for discharge, realizing mechanized sowing of fennel. Among them, the duckbill seed outlet assembly 26 is a commonly used structure for hill seeders in this field. The cotton planter 13 is located in the middle of the wide row of the wide-narrow row configuration of the fennel planter 17, so that cotton and fennel are sown simultaneously, which can improve economic efficiency.

[0044] As an optional solution, in this embodiment, the seeding box includes a seed inlet tray 31, a rotating shell 28, and a seed box 27. The seed inlet tray 31 is fixedly connected to the fixed frame assembly. The rotating shell 28 is annular, with one end fixedly connected to the side wall of the seed box 27 by bolts, and the other end rotatably connected to the seed inlet tray 31, forming a cylindrical receiving cavity. The inside of the seed box 27 is fixedly connected to a rotating sleeve, which is rotatably mounted on a central shaft 32. The central shaft 32 passes through the seed inlet tray 31 and is fixedly connected to the fixed frame assembly. The seed inlet tray 31 is provided with a feed port, which is connected to the seed storage box 16 through a seed guide tube 23. The seed inlet tray 31 is fixed, which facilitates the connection of the seed inlet tray 31 to the seed guide tube 23 to feed seeds from the seed storage box 16. The rotating shell 28 and the seed box 27 rotate during the sowing process to sow seeds. A plate valve is provided below the seed storage box 16. The seed inlet tray 31 has a transparent seed observation port 33, which facilitates the observation of the seeding situation inside the seeder.

[0045] As an optional solution, the fixed frame assembly in this embodiment includes an L-shaped support frame 37, an adjusting screw 25, a contour frame 21, and a fixed frame 22. A reinforcing rib is provided between the two arms of the L-shaped support frame 37. A seed storage box 16 is fixedly connected to the vertical arm of the L-shaped support frame 37, and the contour frame 21 is hinged to the end of the horizontal arm, so that the L-shaped support frame 37 can swing up and down at the hinge axis, so that the seeder can adapt to the undulation of the ground. The fixed frame 22 is connected to one side of the contour frame 21, and the adjusting screw 25 is passed through the end. An adjusting nut is provided on the adjusting screw 25 and is located on the top of the contour frame 21. The fixed frame 22 is connected to the frame 1 by a U-bolt 39. A spring 40 is sleeved on the adjusting screw 25 and is located between the horizontal arm of the L-shaped support frame 37 and the L-shaped support frame 37, so that the seeder can sow according to the undulation of the ground and also has a vibration reduction function.

[0046] As an optional solution, in this embodiment, the fixed frame 22 is an inverted L-shaped plate. U-bolts 39 are connected to the frame 1 via an intermediate support plate 38. A telescopic rod 20, which can be a hydraulic or pneumatic rod, is provided between the intermediate support plate 38 and the horizontal plate of the inverted L-shaped plate. In this embodiment, the row spacing of the seeder can be adjusted by changing the connection position of the U-bolts 39 and the frame 1. The telescopic rod 20 causes the fixed frame 22 to raise and lower the fennel seeder 17, allowing it to be off the ground or grounded, thus enabling the selective sowing of fennel.

[0047] As an optional solution, in this embodiment, a seed-blocking frame 36 is fixedly connected to the center of the seed inlet tray 31. The seed-blocking frame 36 is fan-shaped, and an arc-shaped channel is formed between the edge of the seed-blocking frame 36 and the rotating shell 28. The arc-shaped channel only allows the seed picker 30 and the seed discharge port assembly to pass through, preventing seeds from entering the seed discharge port 29 of the seed discharge port assembly during the rotation of the rotating shell 28. The seed-blocking frame 36 divides the seed chamber of the seed box into a seed-scooping area and a seed-discharging area. The seed-scooping area stores seeds, and the seed-discharging area is located within the arc-shaped channel. The seed picker 30 scoops seeds in the seed-scooping area and discharges seeds in the seed discharge area. The seed-blocking frame 36 can effectively prevent seeds from entering the seed discharge port 29 of the seed discharge port assembly when the seed picker 30 and the seed discharge port assembly are at the bottom.

[0048] As an optional embodiment, the seed extractor 30 includes a seed extracting block with a plurality of seed extracting slots, at least one row of which are provided. Each seed extracting slot includes an expansion port and a narrow opening section connected sequentially from the outside to the inside. The diameter of the narrow opening section is only large enough to accommodate one fennel seed. The expansion port is a cone-shaped structure with a larger outer diameter and a smaller inner diameter. The seed discharging port assembly includes a seed discharging port 29, a seed discharging cover 34, and a limiting baffle 35. The seed discharging port 29 is provided with a seed discharging cover 34, which is inverted U-shaped. One end of the seed discharging cover 34 is sealed and connected to the seed discharging port 29. The rear edge of 9 is suspended between the other end and the rotating shell 28. The space from the seed metering cover 34 to the seed metering port 29 gradually narrows. A limiting baffle 35 is provided on the front edge of the seed metering port 29 to prevent seeds from entering the seed metering port 29 when the seed taker 30 and the seed metering port 29 assembly are at the bottom, thus avoiding excessive seeding. The limiting baffle 35 is set inside the seed metering cover 34, and a seed drop opening is formed between the top of the limiting baffle 35 and the seed metering cover 34. The expansion port is set opposite to the seed drop opening of the seed metering cover 34. The seed drop opening is preferably set in a cone shape to facilitate seed drop. Since fennel seeds are slender and small, ordinary seed scoops take a large amount of seeds, which is wasteful and results in a high sowing density, which is not conducive to the later growth of seeds. In this embodiment, the seed taker 30 is provided with two rows of seed taking grooves, and no more than 12 seeds are taken for hole sowing at a time, which can avoid waste caused by excessive seeds. When the seed-collecting block rotates to the bottom of the rotating shell 28, the seeds are scooped up. When the seed-collecting block rotates to the left side of the rotating shell 28, the seeds fall into the seed-discharging hood 34 due to gravity. Under the rotation of the rotating shell 28, the seeds approach the seed-dropping opening and are discharged from the discharge opening into the duckbill seed-discharging assembly 26 for sowing.

[0049] As an optional solution, in this embodiment, the frame 1 is a lifting and sliding frame, which includes three frame modules 41, a support traction frame 7, a lifting mechanism, and a translation mechanism 2. One end of the support traction frame 7 is used to connect to the traction power equipment, and the other end is connected to a side frame module 41 through two translation mechanisms 2. The two side frame modules are symmetrically slidably connected to the two ends of the support traction frame 7. The upper end of the support traction frame 7 is connected to a frame module 41 located in the middle through a lifting mechanism. The frame module 41 located in the middle is the main frame module. The frames of the three frame modules 41 can be arranged in a coplanar manner. Each frame module 41 is equipped with four cotton planters 13 and one fennel planter 17. The fennel planter 17 is located between two cotton planters 13, which ensures the row spacing of cotton planting while allowing for the optional planting of fennel. The entire device is modularly designed for easy assembly and maintenance. At the same time, the three frame modules 41 can be deformed through the lifting mechanism and the translation mechanism 2, thereby changing the sowing width to adapt to sowing needs of different widths.

[0050] As an optional solution, in this embodiment, one end of the supporting traction frame 7 is provided with a sliding groove, and the crossbars of the two side frame modules are slidably disposed in the sliding groove. One end of the translation mechanism 2 is connected to the supporting traction frame 7, and the other end is connected to the crossbar of the side frame module through a protruding limiting plate, which limits the lateral movement of the side frame module to prevent derailment. The translation mechanism 2 is a hydraulic rod or a pneumatic rod to realize the lateral movement of the side frame module. The length of the supporting traction frame 7 is not greater than the width of the two side frame modules to avoid the length of the supporting traction frame 7 from exceeding the width of the narrowed machine. The front end of the supporting traction frame 7 is provided with a hook 6 for connecting to the drive mechanism of a tractor or other similar device.

[0051] As an optional solution, the lifting mechanism in this embodiment includes lifting components 8, sprockets 10, chains 9, and guide rods 42. Two guide rods 42 are vertically arranged on the supporting traction frame 7. An L-shaped lifting plate is connected to the crossbar of the main frame module. The two guide rods 42 pass through the lifting plate. Two lifting components 8 are vertically arranged, and a sprocket 10 is rotatably connected to the top rod of each lifting component 8. One end of the chain 9 is fixedly connected to the frame 1, and the other end is wound around the sprocket 10 and connected to the lifting plate. The chain 9 is symmetrically connected to both ends of the lifting plate. The lifting components 8 are hydraulic rods or pneumatic rods. A low-position limit lock 24 is provided on the seed box 27 in the middle of the supporting traction frame 7. A retaining ring 44 is provided at one end of the lifting plate, and a high-position limit lock is provided at the other end. The top of the latch 24 and guide rod 42 is provided with a retaining ring 44. The retaining ring 44 on the lifting plate can engage with the lower limit latch 24, and the retaining ring 44 or pin 45 on the guide rod 42 can engage with the higher limit latch 24. The limit latch 24 includes a latch seat 43, a spring 40 and a pin 45. The latch seat 43 is U-shaped. One arm of the latch seat 43 is provided with a sliding groove and the other arm is provided with a insertion interface. One end of the pin 45 is provided with a pin head and the other end is provided with an operating handle. The spring 40 is sleeved on the pin 45. The pin 45 passes through the sliding groove. The spring 40 is located between the pin head and the bottom of the sliding groove. The pin head matches the insertion interface. The pin head and the lower end of the latch seat 43 form a locking ring. The locking ring is used to lock the retaining ring 44. The lifting mechanism utilizes hydraulic rods and the transmission between sprockets and chains to raise and lower the main frame module. When the main frame module reaches its highest point, the high-position limit lock 24 engages with the retaining ring 44 on the guide rod 42 to secure the lifting plate. The lifting height of the seeder is equal to the extension height of the chain 9, which is twice the lifting height of the hydraulic cylinder. When the main frame module lowers, the low-position limit lock 24 engages with the retaining ring 44 on the lifting plate to lock and secure it. The two side frame modules are slidably positioned in the grooves of the support traction frame 7. Hydraulic rods are used to achieve their translational sliding, thereby enabling the entire mechanism to retract and expand. When the entire machine retracts, the main frame module is raised to its highest point, and the two side frame modules slide symmetrically inward to fill the gap, thus reducing the area occupied by the entire machine. When the entire machine is unfolded, the two side frame modules unfold first, and then the main frame module falls to the required position and is fixed by a locking pin, and the entire machine enters the working state.

[0052] As an optional solution, the cotton sowing unit in this embodiment includes, from front to back, a pressing roller 19, a furrowing disc 46, a film pressing roller 3, a cotton sower 13, a soil covering roller 15, and a soil covering disc 18 arranged below the frame 1. A drip irrigation tape support 4, a plastic film support 5, and a soil vibrating frame 14 are arranged above the frame 1. The drip irrigation tape support 4 and the plastic film support 5 are both located in front of the cotton sower 13 and are matched with the position and number of the cotton sower 13. Each frame module 41 is provided with one plastic film support 5, two drip irrigation tape supports 4, a pair of furrowing discs 46, and a pair of soil covering discs 18. The drip irrigation tape of the drip irrigation tape support 4 is arranged on both sides of the fennel sowing (both sides of the wide row spacing of cotton) on the frame module 41. The soil vibrating frame 14 is arranged on the soil covering roller 15. A soil covering disc 18 is arranged on the frame 1 on both sides of the soil covering roller 15. A drip irrigation tape guide 11 is installed below the drip irrigation tape support 4. The drip irrigation tape guide 11 consists of two opposing rollers, through which the drip irrigation tape passes. The cotton planter 13 differs from the fennel planter 17 in that it does not have a telescopic rod 20 for lifting. The cotton planter 13 can adopt a conventional planter structure, connected to a cotton seed box 12, as long as cotton sowing is possible. The fennel planter 17 is arranged side-by-side with the cotton planter 13, and both are preferably hill-planters. The cotton planter 13 typically uses a wide-narrow row configuration. In this embodiment, the wide row spacing of the cotton planter 13 is 66cm, the narrow row spacing is 10cm, the plant spacing is 9cm-10cm, and the sowing depth is 2cm-3cm. The fennel planter 17 is located in the middle of the wide row spacing of the cotton planter 13, equivalent to a row spacing of 33cm with the cotton plants on both sides, a plant spacing of 15cm-20cm, and a sowing depth typically of 1cm-2cm.

[0053] Example 2

[0054] This embodiment provides a specific operating method for a cotton and fennel simultaneous seeding machine:

[0055] The machine in this embodiment includes three frame modules 41 for simultaneous cotton and fennel sowing. When unfolded, the three frame modules 41 are arranged side by side on the same plane, which can carry out wide-width sowing. When retracted, the main frame module in the middle rises up, and the two side seeders slide laterally towards the middle and retract and merge, which can carry out narrow-width sowing. When the seeder is working, as the whole machine moves forward, the ground is first leveled by the press roller 19. As the furrowing disc 46 opens the furrow, the drip irrigation tape and the mulch film on the mulch film frame are laid in sequence under the action of the ground. The drip irrigation tape is laid in the set position by the drip irrigation tape guide to prevent interference with the mulch film. Then, both are pressed firmly on the ground by the film pressing roller 3. After that, the cotton seeder 13 and the fennel seeder 17 carry out precision seeding. After the seeding operation is completed, the soil covering disc 18 fixes the two sides of the mulch film and brings the soil into the soil covering roller 15. The soil is discharged through the gaps on the soil covering roller 15 corresponding to the seed holes and covers the gaps in the mulch film created by the seeding, so that cotton and fennel can be sown at the same time at the set row spacing.

[0056] In this embodiment, a seed box and a fennel planter 17 are installed in the wide rows of cotton sowing. The planter is connected to the frame via a telescopic rod 20. When fennel sowing is not required, the telescopic rod 20 is raised, and the fennel planter 17 is lifted off the ground. When simultaneous cotton and fennel sowing is required, the lifting mechanism is lowered, and the fennel planter 17 is grounded. At the same time, the planter is kept in close contact with the ground surface by means of the contour frame 21, spring 40, and ground undulations to ensure sowing quality. When the fennel planter 17 is working, seeds enter the planter 17 from the seed box through the seed guide tube 23 on the seed inlet tray 31. Simultaneously, the seed-collecting belt rotates under the drive of the main shaft of the fennel planter 17. The seed collector 30, fixed on it, scoops up the seeds as it passes the lower semicircle of the seed metering device. Each hole in the seed collector 30 is filled with one fennel seed, ensuring precise sowing of the fennel seeds. This process is called the seed filling stage. As the seed metering device rotates, the seed collector 30 gradually rises. When the seed-collecting holes face downwards, the fennel seeds fall into the duckbill seed metering assembly 26 under gravity. Finally, the fallen seeds are discharged from the planter through the seed outlet 29 and fall into the seed holes, completing the sowing process. A seed observation port 33 is located on the seed inlet tray 31 for easy observation of the seed metering process inside the planter.
