[0049] 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.

[0050] This invention specifically provides a multi-functional precision seeder, please refer to... Figures 1-13 The system includes a body 1, with a storage compartment 2 fixedly installed on top of the body 1. The body 1 has a frame-type installation structure and a bolt mounting plate structure at its bottom for fixed connection with an external transport vehicle structure, so that the body 1 can be transported by the transport vehicle to achieve the purpose of mobile sowing.

[0051] The storage chamber 2 is equipped with a sowing component 3. After the seeds to be sown are sent into the storage chamber 2, they fall onto the sowing component 3 for sowing. The sowing component 3 is connected to the switching component 4. The machine body 1 is equipped with a drive component 5 to provide kinetic energy support for the operation of the sowing component 3. The sowing component 3 is equipped with a sowing wheel 6. After the seeds fall into the sowing component 3, different types of seeds can switch the sowing mode of the sowing wheel 6 through the switching component 4, so that the sowing wheel 6 can adapt to the quantitative sowing needs of different types of seeds. The machine body 1 is equipped with a protective component 7 to cover the sowing component 3 to provide dustproof and airtight protection. The protective component 7 can be quickly opened and closed to detach from the sowing component 3 when it is working.

[0052] Specifically, the storage chamber 2 includes a chamber body 21 whose bottom end is fixedly connected to the body 1. The bottom of the chamber body 21 is provided with symmetrical inclined surfaces 22. An installation pipe 23 is fixed on one of the inclined surfaces. The installation pipe 23 is used to connect to the conveying pipe of the external seed conveying mechanism, so that the seeds can be conveyed and enter the chamber body 21 through the installation pipe 23, and be fed into the direction of the sowing component 3 along the inclined surface 22. The seed conveying mechanism can be set on the conveying vehicle structure that is integrated with the body 1, so as to provide seeds to the storage chamber 2 as needed when moving.

[0053] In practice, the seeding components 3 are arranged in a line along the length of the machine body 1. The seeding components 3 are fixedly connected to the machine body 1 to form a fixed whole. The bottom of the bin 21 is an open structure, so that after the seeds fall into the contents of the bin 21, they can fall into the seeding components 3 from the open along the inclined surface 22. The seeding components 3 include a seeding frame 31 and a seeding tube 32 connected to the seeding frame 31. The outside of the seeding frame 31 is fixedly connected to the machine body 1. The seeding tube 32 is set at the discharge port of the seeding frame 31, so that the seeds can be sown and discharged from the seeding frame 31 through the seeding tube 32.

[0054] Furthermore, the seeding frame 31 includes a frame body and a material drop trough 311 opened on the frame body. After the seeds fall from the opening, they will fall into the material drop trough 311. The bottom of the material drop trough 311 is connected to the seeding trough 313. A guide slope 312 is provided between the material drop trough 311 and the seeding trough 313. The guide slope 312 is arranged symmetrically in the material drop trough 311, so that after the seeds fall into the material drop trough 311, they can be sent towards the seeding trough 313 along the guide slope 312.

[0055] The seeding trough 313 has a wheel groove 314 that is parallel to its length direction. The wheel groove 314 and the frame are respectively provided with a seeding opening 315 and an air vent 317. The wheel groove 314 is used to install the seeding wheel 6 so that the seeds can be transported by the seeding wheel 6 on the wheel groove 314 after falling into the seeding trough 313, so as to carry out quantitative seeding.

[0056] Specifically, a fan is installed inside the body 1, preferably a blower, which is fixedly installed on the back of the body 1. The top of the wheel groove 314 is provided with an opening for seeding, so that the top of the sowing wheel 6 can be exposed in the sowing trough 313 through the opening. The frame is provided with a sowing channel 316 and a ventilation channel 318, the tops of which are respectively connected to the sowing port 315 and the air vent 317. The conveying end of the fan is connected to the sealing port 317, so that the auxiliary sowing airflow can be sent from the ventilation channel 318. Seeds are introduced into the sowing channel 316, which is connected to the ventilation channel 318 in a V-shape. This allows the seeds to fall freely along the inclined path of the sowing channel 316 after entering it. The connection between the ventilation channel 318 and the sowing channel 316 is at the bottom of the sowing channel 316. Once the seeds have fallen to the bottom of the sowing channel 316, they will be blown towards the outlet of the sowing channel 317 by the airflow from the ventilation channel 318.

[0057] The bottom end of the seeding channel 316 is fixedly connected to the seeding tube 32, so that the seeds can fall out of the seeding tube 32 after falling into the outlet of the seeding channel 316.

[0058] Furthermore, the seeding wheel 6 operates in a rotating state. The seeding wheel 6 includes a wheel body 61 that is rotatably disposed in the wheel groove 314. The outer side of the wheel body 61 rotates and fits against the inner wall of the wheel groove 314, and the top of the wheel body 61 protrudes from the opening structure at the top of the wheel groove 314, so that the seeds can accumulate on the top side of the wheel body 61 after falling into the seeding trough 313.

[0059] In implementation, the wheel body 61 is provided with seeding troughs 62 arranged in a circumferential array. There are three concentric circles of seeding troughs 62 on the wheel body 61. Seeding troughs 62 in the same circle are of the same type, while seeding troughs 62 in different circles are of the same type but different from each other. That is, different concentric circles of seeding troughs 62 can be set up to plant different types of seeds such as corn, rice, and sorghum, according to the planting needs. Since the wheel body 61 rotates circumferentially during implementation, it is normally located below the guide slope 312, which will drive the rotation of one concentric circle of seeding troughs 62. After the seeds fall into the grooves 314 above the wheel, they can first fall into the grooves located at the top of the wheel body 61, which are the same size as the seeds. The seeds are placed in the seeding trough 62. As the wheel 61 rotates forward, the seeds in the seeding trough 62 rotate and fall into the inner wall of the wheel groove 314. Since the outer wall of the wheel 61 is in contact with the inner wall of the wheel groove 314, the seeds will not leak out of the wheel groove 314. After the wheel 61 rotates, the seeds in the seeding trough 62 pass through the seeding opening 315 and fall out of the seeding opening 315 due to gravity and rotational inertia. Since the seeding troughs 62 are equidistantly spaced on the wheel 61, the seed delivery mode can be achieved more accurately, realizing the technical means of quantitative seeding.

[0060] Furthermore, the protective component 7 includes an outer protective plate 71 disposed on the outside of the machine body 1, an opening and closing component 72 connected to the outer protective plate 71, and an inner protective plate 73 for connecting to the frame. The outer protective plate 71 can provide impact and dust protection for the seeding component 3.

[0061] The opening and closing assembly 72 includes a fixed rod 721 with both ends fixedly connected to the body 1. The left and right sides of the fixed rod 721 are rotatably connected to the rotating frame 722. The number of rotating frames 722 is set to two, which are spaced apart. The two rotating frames 722 are fixedly connected by a push rod 723.

[0062] In practice, the top of the outer protective plate 71 is rotatably connected to the fixed rod 721, and the inner side of the outer protective plate 71 is in contact with the push rod 723. That is, when the push rod 723 rotates outward, it can apply an outward pushing force to the outer protective plate 71 so that the outer protective plate 71 can be opened quickly. The outer side of the machine body 1 is provided with a placement port 12. The outer side of the push rod 723 is in sliding contact with the placement port 12. The inner contour of the placement port 12 matches the movement path of the push rod 723. After the push rod 723 is placed in the placement port 12, it is restricted by the stroke movement of the end of the placement port 12, so that the push rod 723 cannot move inward. Thus, after the outer protective plate 71 is impacted, it can be resisted by the push rod 723 to offset part of the impact force and avoid the outer protective plate 71 from colliding with the seeding component 3.

[0063] When operation is required, the rotating frame 722 can be quickly rotated outward, causing the rotating frame 722 to drive the push rod 723 to rotate the outer guard plate 71 outward and open.

[0064] The inner protective plate 73 includes an insert plate 731 and an operating block 732 fixed to the outside of the insert plate 731. The inner protective plate 73 is used to provide a sealed dustproof protection for the seeding component 3 when it is idle. It can also reduce contact with external gases and extend its service life. The number of inner protective plates 73 is the same as the number of seeding components 3. When the seeding component 3 needs to work, the insert plate 731 can be moved out by moving the operating block 732.

[0065] During implementation, an insertion port 319 is provided on the outside of the frame, and a placement surface 33 is provided in the material drop groove 311 that is at the same level as the bottom surface of the insertion port 319. After the insertion plate 731 is inserted into the insertion port 319, its bottom surface fits against the placement surface 33.

[0066] Furthermore, the drive assembly 5 includes a combing assembly 51 and a drive box 52 disposed on the body 1. The drive box 52 is an existing mature mechanical component, which contains a motor and a gear set. After the motor drives the gear set to rotate, the rotation output can be transmitted to the externally connected components to achieve the effect of kinetic energy support.

[0067] Specifically, the combing component 51 is located above the sowing component 3 to rotate and disperse the seeds on the sowing component 3, reducing material blockage. The combing component 51 includes a mounting rod 511 rotatably mounted on the machine body 1. Fixed cylinders 512 are fixedly mounted on the mounting rod 511 at intervals. The number and position of the fixed cylinders 512 match the sowing component 3. The drive box 52 is provided with multiple output ends. The mounting rod 511 is connected to one of the output ends of the drive box 52. The drive box 52 drives the mounting rod 511 to rotate. A combing frame 513 is fixedly mounted on the outside of the fixed cylinder 512, so that when the mounting rod 511 rotates, it will drive the fixed cylinder 512 to rotate, thereby causing the combing frame 513 to rotate and disperse the seeds accumulated above the wheel body 61, avoiding seed accumulation and material blockage.

[0068] Furthermore, to meet the sowing needs of different types of seeds, the switching component 4 includes a shaft 41 rotatably mounted on the machine body 1 and a moving component 42 set on the shaft 41. A bearing is embedded in the connection between the machine body 1 and the shaft 41, and the bearing is connected to the outside of the shaft 41, so that the shaft 41 can meet the rotation requirements and can then move along its axial direction.

[0069] The axle 41 has a polygonal shape, which facilitates circumferential rotation and lateral movement. The wheel 61 is fixedly connected to the outer side of the axle 41. The rotation of the axle 41 can drive the wheel 61 to rotate synchronously. The axle 41 can move the wheel 61 laterally through the moving component 42, thereby changing the position of the seeding trough 62 of different rings to adapt to different types of seeds.

[0070] Specifically, the end of the shaft 41 away from the moving component 42 is connected to the other output end of the drive box 52 so that the shaft 41 can be rotated by the drive box 52. A mounting base 11 is fixedly provided on the outside of the machine body 1, and an inner cylinder 43 is provided on the outside of the shaft 41. A locking rod 431 with its inner end fixedly connected to the shaft 41 is fixedly installed on the inner cylinder 43 so that when the shaft 41 rotates, it can drive the inner cylinder 43 to rotate synchronously. At the same time, the shaft 41 and the inner cylinder 43 can be kept as one unit.

[0071] The movable component 42 includes a threaded sleeve 421 whose inner wall is rotatably connected to the shaft 41, and a switching disk 422 fixedly connected to the outer end of the threaded sleeve 421. The outer side of the threaded sleeve 421 is threadedly connected to the pressure plate 423. Furthermore, the threaded sleeve 421 is slidably provided with a retainer 424, and a fixed seat 425 is provided on the side of the retainer 424 away from the pressure plate 423. The outer side of the fixed seat 425 is fixedly connected to the mounting base 11. The threaded sleeve 421 has a cylindrical groove 432 inside, and the inner wall of the cylindrical groove 432 is rotatably connected to the inner cylinder 43, so that when the shaft 41 rotates, it can rotate stably in the cylindrical groove 432 through the inner cylinder 43. The outer side of the threaded sleeve 421 is threadedly connected to the fixed seat 425. When it is necessary to adjust the axial position of the shaft 41 and adjust the seeding trough 62, when the machine is stopped, the threaded sleeve 421 is rotated on the fixed seat 425 by rotating the switching disc 422, thereby realizing the lateral movement of the threaded sleeve 421, driving the shaft 41 to move laterally, and realizing the lateral switching of the seeding trough 62.

[0072] It is worth noting that a locking block 426 is fixedly installed on the outside of the locking seat 424, and a locking groove 427 for inserting into the locking block 426 is provided on the fixed seat 425. Before the threaded sleeve 421 is rotated, the pressure plate 423 needs to be rotated first, so that the pressure plate 423 moves away from the fixed seat 425. Then, the locking seat 424 is pushed towards the position of the pressure plate 423, so that the locking seat 424 can be separated from the fixed seat 425. At this time, the threaded sleeve 421 can be rotated. After that, the locking seat 424 can be reset, so that the locking seat 424 is pressed against the fixed seat 425 under the pressure of the pressure plate 423, making it more difficult for the threaded sleeve 421 to rotate, thereby improving the stability effect after the shaft 41 is displaced.

[0073] Furthermore, the machine body 1 is equipped with an adjustment component 8 that can control the sowing density. The adjustment component 8 is fixedly connected to the sowing tube 32 so that the sowing density of the seeds can be quickly adjusted during sowing and material discharge.

[0074] The adjustment component 8 includes an installation chamber 81 fixedly connected to the machine body 1 on the outside and an adjustment pipe 82 connected to the seeding pipe 32. The adjustment pipe 82 is connected to the adjustment frame 83 on the outside. The adjustment frame 83 drives the adjustment pipe 82 to move through the drive component to adjust the seeding density.

[0075] Specifically, the regulating pipe 82 includes a spiral pipe 821, which is a spiral-shaped spring pipe made of spring steel. It has good elasticity and hardness and can be coaxially compressed like a spring after being subjected to force. One end of the spiral pipe 821 is slidably connected to the mounting chamber 81, and the other end is fixedly installed with a closing pipe 822. A sleeve 811 is fixedly installed on the mounting chamber 81. The inner wall of the sleeve 811 is slidably connected to one end of the spiral pipe 821, thereby providing stable subsequent sliding support. The closing pipe 822 has a conical structure and is fixedly connected to the discharge port of the sowing pipe 32. The larger opening of the closing pipe 822 is connected to the sowing pipe 32, so that after the seeds are discharged from the sowing pipe 32, they can fall into the spiral pipe 821 through the closing pipe 822 and be discharged along the spiral structure of the spiral pipe 821 under the drive of the auxiliary airflow.

[0076] In practice, when it is necessary to control the discharge density of seeds outside the spiral tube 821, it is only necessary to control the degree of compression of the spiral tube 821. When it is necessary to reduce the density, the spiral tube 821 can be compressed. The compression stroke should not affect the normal transport of seeds. After the spiral tube 821 is compressed, the movement stroke of seeds in the tube increases, the discharge speed decreases, and the density at discharge decreases. Therefore, when it is necessary to reduce the discharge density of seeds to meet the needs of sparse sowing, the spiral tube 821 can be compressed.

[0077] Among them, a force-receiving plate 823 is fixedly installed on the outside of the spiral tube 821, and the spiral tube 821 is subsequently connected to the adjusting frame 83 through the force-receiving plate 823.

[0078] Specifically, the adjusting frame 83 includes a roller 831 rotatably mounted on the force-receiving disk 823 and a cam 832 on the outside of which is in contact with the roller 831. The cam 832 is fixedly mounted on the outside of the rotating rod 833, which is rotatably disposed in the mounting chamber 81. That is, when the rotating rod 833 rotates, it will drive the cam 832 to rotate, so that the cam 832 can push the roller 831 backward after rotation, causing the roller 831 to drive the force-receiving disk 823 to move backward in a straight line, so that the spiral tube 821 can be compressed to a certain length. Then the rotating rod 833 stops, and the cam 832 maintains the force applied to the roller 831, so that the spiral tube 821 can maintain the discharge state.

[0079] The drive assembly is mounted on the body 1 and includes a motor 841 fixedly mounted on the outer side of the body 1. The output shaft of the motor 841 is fixedly connected to a worm gear 842. The outer side of the worm gear 842 meshes with a worm wheel 843. The worm wheel 843 is coaxially fixed to the outer end of the rotating rod 833, thereby driving the rotating rod 833 to rotate through the worm wheel 843. At the same time, the self-locking structure of the worm gear 842 and the worm wheel 843 can keep the rotating rod 833 self-locked after rotation, preventing the cam 832 from shifting, thus ensuring the stable use of the spiral tube 821. The motor 841, worm gear 842 and worm wheel 843 are provided with a housing 844 fixedly connected to the body 1 to provide dustproof and impact-proof protection for the relevant components.
