[0026] The Cotton Filmless Seeder and Fertilizer Apparatus is a piece of agricultural machinery designed specifically for cotton cultivation without mulch. It aims to address the increased soil pollution and costs associated with traditional mulch mulching, while also enabling precise seeding and efficient fertilization. Device Type and Technical Features: The dedicated hole seeder includes a duckbill assembly with a bearing feed tube and a quickly removable protective ring plate. The assembly and disassembly mechanism allows tool-free maintenance, improving cleaning efficiency. Advantages: Suitable for precision seeding of cotton without mulch. Its corrosion-resistant design extends its service life, and it eliminates the need for mulch mulching, reducing environmental pollution. The floating seeding and fertilization seeder combines seedbed preparation, deep fertilization, seeding, soil covering, and shaping. It features a weed-clearing mechanism, a fertilizer opener, and a floating seeding mechanism. The seeding depth is adjusted by a spring, adapting to complex terrain such as stubble-covered fields. The linkage between the isolation wheel and the pressure wheel prevents fertilizer burns and improves seed emergence. A cam track drives the pusher block for precise seed placement and placement. A torsion spring-loaded snap-on mechanism opens and closes the mouthpiece for seed placement, making it suitable for small-scale or manual operations. In the future, it may be possible to combine intelligent monitoring and variable fertilization technology to further improve the accuracy of filmless seeding.

[0027] The prior art discloses a cotton filmless cultivation under-seed fertilization and sowing device, comprising: a connecting frame, supporting and connecting various parts of the working equipment, and multiple fertilization and sowing devices are connected in series through the connecting frame to form a fertilization and sowing machine; a movable roller, rotatably fixed to one end of the connecting frame; a flattening device, fixed to the end of the connecting frame opposite to the movable roller; a fertilizing device, fixed to the connecting frame, located at the end close to the movable roller; a sowing device, fixed to the connecting frame, located between the fertilizing device and the flattening device; a transmission device, rotatably fixed to the side of the connecting frame; a V-shaped buried baffle, fixed to the connecting frame, and with the open end facing the direction of the movable roller. The fertilization device includes: a fertilizer storage box, whose side walls are fixed on the connecting frame to store fertilizer; a fertilizer distribution wheel, which is rotatable and fixed on the bottom of the fertilizer storage box, and during the rotation, the fertilizer is quantitatively transported; a fertilizer delivery pipe, which is connected to the bottom of the fertilizer distribution wheel to transport and transfer the fertilizer; a fertilizer hopper, which is arranged under the fertilizer delivery pipe to collect the fertilizer passing through the fertilizer delivery pipe; a fertilizer furrow opener, which is fixed on the fertilizer hopper and has both sides fixed on the connecting frame. During the movement, the land is furrowed, and the fertilizer in the fertilizer hopper continues to fall to carry out fertilization. The fertilizer distributing wheel includes: a rotating shaft, which is fixedly connected to the transmission device and rotates under the drive of the transmission device, thereby driving the fertilizer distributing wheel to rotate as a whole to transport the fertilizer; a telescopic inner shaft, one end of which is fixedly connected to the rotating shaft and rotates following the rotating shaft; an outer shaft, which is divided into a fixed outer shaft and a sliding outer shaft, which are respectively fixed on two sections of the telescopic inner shaft and are rotatably connected to the side wall of the fertilizer storage box. Under the action of the rotating shaft, the telescopic inner shaft drives the outer shaft to rotate; a movable shaft, which is fixedly connected to the telescopic inner shaft and fixedly connected to a section of the outer shaft away from the rotating shaft. By moving the movable shaft, the telescopic inner shaft is driven to extend and retract, and then the sliding outer shaft is driven to move, thereby adjusting the distance between the fixed outer shaft and the sliding outer shaft, thereby changing the amount of fertilizer transported by the fertilizer distributing wheel each time. The fixed outer shaft is rotatably fixed to the side wall of the fertilizer storage box, the sliding outer shaft is rotatably connected to the side wall of the fertilizer storage box, and the sliding outer shaft can slide on the outer wall of the fertilizer storage box. Under the action of external force, the movable shaft is moved, thereby driving the telescopic inner shaft to retract. Since the fixed outer shaft and the side wall of the fertilizer storage box are in a rotatable and fixed state, that is, the position of the fixed outer shaft remains unchanged, the sliding outer shaft moves, and then the distance between the fixed outer shaft and the sliding outer shaft is adjusted.

[0028] The sowing device includes: a seed storage box fixed on a connecting frame for storing seeds; a quantitative rotary disk rotatably fixed inside the seed storage box, and sequentially conveying the seeds in portions during rotation; two delivery pipes symmetrically arranged and fixed to the bottom of the seed storage box for conveying the quantitative seeds; a rotating shaft, the top of which passes through the center of the bottom of the seed storage box and is fixedly connected to the quantitative rotary disk, driving the quantitative rotary disk to rotate, thereby quantitatively distributing the seeds; a right-angle gearbox arranged on the rotating shaft and driving the rotating shaft to rotate; a transmission shaft connecting the right-angle gearbox and the transmission device, and driven by the transmission device to rotate the transmission shaft, thereby driving the rotating shaft to rotate through the right-angle gearbox, and then driving the quantitative rotary disk to rotate, thereby quantitatively distributing the seeds; a mixing rotary disk fixed to the bottom of the rotating shaft and driven by the rotating shaft to rotate and mix the fertilized soil to prevent excessive accumulation of fertilizer; and two sowing furrow openers symmetrically arranged on both sides of the fertilizing furrow opener, with the tops fixed to the connecting frame. During movement, the soil is furrowed, and the delivery pipes convey the seeds to the cultivated furrows. The bottom of the seed storage box is equipped with holes corresponding to the delivery tube, and these holes correspond to the metering disc. Driven by the metering disc, the seeds rotate and fall into the delivery tube when passing through the holes. From there, they fall into the trench created by the seeding opener. The bottom of the mixing disc and the bottom of the fertilizing opener are at the same level to ensure that the mixing disc contacts the fertilizer without damaging the fertilizing trench. The bottom plane of the seeding opener is higher than that of the fertilizing opener, and the trenching depth of the fertilizing opener is 5-7cm. This ensures that the fertilizer and seeds are in different soil layers, while ensuring the fertilizer's effectiveness is maximized while preventing direct contact with the seeds and causing damage. The transmission device includes: sprocket one, which is fixed to one side of the mobile roller and rotates under the drive of the mobile roller; sprocket two, which is fixed on the transmission shaft and rotates synchronously with the transmission shaft; sprocket three, which is fixed on the rotating shaft and rotates synchronously with the rotating shaft; a sprocket group, which is fixed on the connecting frame and is located between sprocket one and sprocket two; chain one, which connects sprocket one, sprocket two and sprocket group, and under the action of the mobile roller, sprocket one rotates, drives the sprocket group and sprocket two to rotate through chain one, and then drives the transmission shaft to rotate through sprocket two, thereby driving the sowing device to operate; chain two, which connects sprocket three and sprocket group, and when the sprocket group rotates under the drive of sprocket one, the sprocket group drives sprocket three to rotate under the action of chain two, thereby driving the rotating shaft to rotate, and then driving the fertilizer distribution wheel to rotate as a whole to transport fertilizer. The bottom plane of the burying baffle is lower than the bottom plane of the sowing furrow opener, that is, the sown seeds are higher than the bottom plane of the burying baffle. When the burying baffle moves, it drives the seeds on both sides to move toward the central fertilization ditch and buries the seeds. Under the action of the flattening device, the land is properly leveled and compacted.A plurality of fertilizing and sowing devices are arranged together to form a fertilizing and sowing machine, which is driven by a machine to work. First, fertilizer and seeds are added to the fertilizer storage box and the seed storage box respectively. The moving shaft is moved according to the amount of fertilizer, and the middle spacing of the outer shaft is adjusted. Then, the machine is driven to perform fertilizing and sowing work. During the movement, the fertilizer furrow opener and the sowing furrow opener perform furrowing work at the same time, and under the action of the transmission device, the fertilizer distribution wheel, the quantitative turntable and the mixing turntable rotate at the same time to complete the fertilizer transportation, seed sowing and fertilizer mixing work, and then the sowing channels on both sides of the fertilization channel drive the seeds to move to the middle fertilization channel under the action of the burying baffle to complete the burying work, and then under the action of the rear flattening device, appropriate leveling and compaction are carried out to complete the fertilization and sowing work.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-Figure 7 As shown, this embodiment provides a filmless sowing and fertilizing device for sowing cotton after wheat stubble, including a connecting frame 1, a plurality of furrowing components are arranged on the bottom surface of the connecting frame 1, and an adjusting mechanism 5 is installed on the top of the furrowing component. The adjusting mechanism 5 can control the depth of the furrowing component extending into the soil and the furrowing width. The furrowing component includes a fertilizer shovel 3 and a seeder 2. A plurality of fixing frames 10 are fixedly connected to the side wall of the connecting frame 1, and the plurality of fixing frames 10 are arranged corresponding to the plurality of seeders 2. A water tank 9 is installed on the fixing frame 10, and a water outlet pipe 6 is connected to the bottom of the water tank 9, and the bottom of the water outlet pipe 6 faces the seeder 2. The fertilizer shovel 3 is connected to the fertilizer box 8 through the adjusting mechanism 5, and the seeder 2 is connected to the seed box 7 through the adjusting mechanism 5. The seed box 7 and the fertilizer box 8 are respectively fixedly mounted on the top surface of the connecting frame 1, one side of the connecting frame 1 is connected to the external traction mechanism, and the other side of the connecting frame 1 is installed with an auxiliary pipe wheel and a burying mechanism. The burying mechanism is used to fill the seed furrow and the auxiliary pipe furrow and clean up the wheat stubble and weeds.

[0032] The present invention integrates a connecting frame 1, a furrowing assembly, an adjusting mechanism 5, a fertilizer, a seeder 2, a water tank 9, a fertilizer box 8, a seed box 7, an auxiliary pipe wheel, a traction mechanism and a burying mechanism. A stubble-removing device (not shown in the figure) is also provided in front of the connecting frame 1. The wheat stubble is removed by the stubble-removing device, and then the furrow is opened by the seeder 2 and the fertilizer shovel 3. The fertilizer and seeds fall into the furrow respectively through the adjusting mechanism 5. The adjusting mechanism 5 can adjust the height of the seeder 2 and the fertilizer shovel 3 to be suitable for different plots. After the seeds fall, the water in the water tank 9 falls into the furrow through the outlet pipe 6, thereby improving the seed germination rate. At the same time, an auxiliary pipe device (not shown in the figure) is also provided on the connecting frame 1, wherein the auxiliary pipe pulley is located behind the seeder 2. In order not to affect the germination and later growth of the seeds, the auxiliary pipe is located on the side of the sowing row and kept parallel to the sowing row, so as to facilitate the subsequent drip irrigation operation and provide the required moisture for the later growth of the cotton. After the sowing is completed, the furrow is filled and compacted by the burying mechanism, and the weeds are removed at the same time. The present invention can realize the integrated operation of trenching, fertilizing, sowing, irrigation, covering soil and weeding, mechanize the whole process, reduce manual intervention and improve work efficiency; and the trenching depth is controlled by the adjustment mechanism 5 to adapt to different soil textures and cotton variety requirements; at the same time, the fertilizer shovel 3 and the seeder 2 are independently designed to avoid direct contact between fertilizer and seeds, prevent seed burning and improve the germination rate; in addition, the water tank 9 and the water outlet pipe 6 are directly facing the sowing area, realizing local precision irrigation and reducing water resource waste.

[0033] Further detailing the scheme, the adjustment mechanism 5 comprises a sleeve 17 and a fertilizer drop pipe 18. The fertilizer drop pipe 18 can move vertically along the sleeve 17. The top of the fertilizer drop pipe 18 communicates with the fertilizer bin 8, and the bottom of the sleeve 17 communicates with the fertilizer shovel 3. A locking assembly is mounted on the sleeve 17, which is detachably connected to the fertilizer drop pipe 18. This allows for quick adjustment of fertilization / seeding depth based on soil moisture conditions and planting requirements, enhancing operational flexibility. The nested design of the sleeve 17 and fertilizer drop pipe 18 eliminates the need for an external adjustment mechanism 5, reducing the complexity of the device.

[0034] To further refine the solution, the locking assembly includes a block 21, with a gear 25 fixedly connected to one side of the block 21, a rack fixedly connected to the outside of the fertilizer drop pipe 18, the gear 25 meshing with the rack, and a screw 22 rotatably connected to the side of the block 21 away from the gear 25. The screw 22 extends out of the sleeve 17 and is fixedly connected to the knob 23, and the screw 22 is threadedly connected to the sleeve 17. When the gear 25 and the rack are engaged, the sleeve 17 and the fertilizer drop pipe 18 are fixed. By turning the knob 23, the screw 22 rotates, the screw 22 moves outward, and then drives the block 21 to move. The block 21 drives the gear 25 to move, disengaging the gear 25 and the rack. At this time, the height can be adjusted. After the adjustment is completed, continue to lock.

[0035] Further detailing the solution, a chute 24 is formed transversely on the sleeve 17, and the block 21 is located in the chute 24 and is slidably connected to the chute 24. A groove 20 is formed longitudinally on the sleeve 17, and the rack is located in the groove 20 and is slidably connected to the groove 20. The provision of the groove 20 can prevent the fertilizer drop pipe 18 from shifting, ensuring accurate fertilization or sowing position. The chute 24 limits the block 21, facilitating the height adjustment of the fertilizer shovel 3 or the seeder 2, and extending the service life of the mechanism.

[0036] Further detailing the scheme, the burying mechanism includes a connecting plate 13, with several long needles 15 fixedly attached to its sidewalls. A burying plate 14 is fixedly attached to the side of the connecting plate 13 facing away from the long needles 15. A storage bucket 11 is fixedly attached to the top of the burying plate 14. This storage bucket 11 houses a rotating crushing assembly and has an opening 12 on the side facing the connecting plate 13. The burying plate 14 compacts the soil, reducing water evaporation and promoting seed germination. The long needles 15 pick up weeds and deliver them to the storage bucket 11, reducing competition in the field and improving the cotton growing environment.

[0037] Further detailing the scheme, the rotary pulverizing assembly includes a motor 29, the output end of which is fixedly connected to a connecting shaft 30. A rotating roller 26 is positioned outside the connecting shaft 30. A plurality of spikes 27 are arranged in an array on the outer side of the rotating roller 26. These spikes 27 draw weeds into the storage bin 11 and crush them. The rotary pulverizing assembly can replace manual or chemical weed control, reducing production costs and meeting the environmental requirements of filmless cultivation. The array of spikes 27 improves weed collection and pulverization efficiency and prevents entanglement and clogging.

[0038] Further detailing the solution, a partition 28 is fixedly attached to the storage tub 11. A motor 29 and rotating roller 26 are located on either side of the partition 28. A connecting shaft 30 passes through the partition 28 and is rotatably connected to it. The partition 28 prevents weeds from entangled with the motor 29 shaft, ensuring stable operation of the device. The partition 28 is also removable, making it easy to clean weeds and inspect components.

[0039] Further detailing the solution, a raised portion 16 is located in the middle of the long needle 15. This portion facilitates the feeding of wheat stubble and weeds onto the connecting plate 13, where they are collected and crushed by the collection bucket 11. This portion guides the weeds along the long needle 15 and onto the connecting plate 13, improving collection efficiency. This portion also increases the structural strength of the long needle 15, enhancing its soil-breaking ability.

[0040] To further refine the solution, a connecting rod 31 is symmetrically fixedly connected to the top of the connecting plate 13, and the end of the connecting rod 31 away from the connecting plate 13 is fixedly connected to the connecting frame 1. The symmetrical design of the connecting rod 31 can balance the force of the burying mechanism and prevent deviation during operation.

[0041] Further detailing the solution, the connecting frame 1 has two rotatably connected running wheels 4 at each end. The presence of running wheels 4 facilitates the device's movement across the field, reduces tractor load, and reduces energy consumption. The wheel diameter and tread are adjustable to accommodate different soil types, such as clay and sand.
