Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to an intelligent self-controlled mulching sorghum and black rice sowing device. Background Art

[0002] Sorghum umbellata is an edible fungus that grows on the top of sorghum. It is mainly distributed in Jilin Province and other places in my country. Its planting usually adopts the hole sowing method. In the existing technology, the hole sowing process of sorghum umbellata includes the following steps: manually digging a seed trench with a hoe or shovel, the depth of the seed trench is generally 5 cm to 7 cm, 5 to 6 sorghum seeds are placed in each hole, and then the mixed fungus soil is covered on the seeds, the thickness of the fungus soil is 2 cm to 3 cm, and finally the soil on both sides of the seed trench is backfilled into the seed trench, the thickness of the soil is 4 cm to 6 cm, and it is compacted. The hole sowing method can increase the contact area between the fungus and the seeds by placing the seeds and fungus soil in the seed trench, thereby improving the inoculation rate.

[0003] However, the manual hole sowing method in the existing technology has certain drawbacks. Since sowing and covering with fungus soil mainly rely on manual operation, the operator needs to place the seeds in the seed furrow first, and then manually spread the fungus soil to cover the seeds. The timing of seed falling and fungus soil covering is difficult to coordinate accurately, resulting in poor uniformity of fungus soil coverage. The fungus soil thickness above some seeds may be less than 2 cm, while the fungus soil thickness in other areas may exceed 3 cm. This uneven covering state affects the contact tightness between the seeds and the fungus soil, thereby reducing the inoculation rate and yield stability of sorghum black rice. Summary of the Invention

[0020] 2. The present invention adopts a control system that combines a PLC controller with multiple sensors.

The flanks push the soil to the sides, forming a uniform seed furrow on the ground.

[0057] 2. Seeding stage

[0058] As the device continues to advance, the seeding component 4 begins to operate. The seeding component 4 comprises a socket-wheel seeding device, a seeding tube 16, and a seed guide tube. The socket-wheel seeding device is secured to the center of the device frame via a seeding device mounting bracket 15. The socket-wheel seeding device comprises a seeding wheel 31, which is a disc-shaped structure with six semicircular grooves 32 evenly distributed along its circumference. A drive motor 14 rotates the seeding wheel 31 via a coupling 13. The central axis of the seeding wheel 31 is supported by bearings within the seeding device housing. The housing has a feed port at the top and is connected to the seeding tube 16 at the bottom. Seeds enter the housing through the feed port and, as the seeding wheel 31 rotates, arc-shaped seed guide slots are provided in the seeding holes 32 along the forward direction. Seeds enter the seeding holes 32 through the seeding slots, allowing each hole to hold 5 to 6 seeds. When the seed wheel 31 rotates to the bottom of the housing, seeds fall through the shaped holes 32 into the seed tube 16. The seed tube 16 is a cylindrical metal tube with a gradually decreasing diameter. The seeds pass through the seed tube 16 and into the seed guide tube, a vertical cylindrical metal tube with its bottom facing the seed trench. The seeds fall into the trench through the seed guide tube. A photoelectric sensor is mounted on the outer wall of the seed guide tube. This cylindrical structure is secured by a U-shaped clamp. When the photoelectric sensor detects a seed passing through the seed guide tube, it outputs a signal to the PLC controller in the control and drive unit 6.

[0059] 3. Intermittent soil covering stage

[0060] The intermittent covering component 3 starts to move as the device advances. The intermittent covering component 3 includes a fertilizer box, an auger 18, an upper fertilizer box 25, a lower fertilizer box 23, a quality sensor, a thrust electromagnet 20, a baffle 24 and a flap 30. The fertilizer box is a trapezoidal structure made of transparent acrylic material. It has a feed port on the top and is connected to the upper fertilizer box 25 at the bottom. A disturbance shaft 19 is provided in the fertilizer box. The disturbance shaft 19 is a cylindrical metal rod with multiple rectangular disturbance plates welded on the surface. The disturbance shaft 19 is supported on the inner wall of the fertilizer box by bearings. The stirring motor 29 drives the disturbance shaft 19 to rotate through a coupling. The disturbance plates rotate with the disturbance shaft 19 to stir the fungus soil in the fertilizer box. The auger 18 is a spiral metal structure, arranged horizontally along the length of the upper fertilizer box 25. Both ends of the auger 18 are supported on the inner wall of the upper fertilizer box 25 by bearing three 17. The auger drive motor 26 drives the auger 18 to rotate through coupling two 27. The auger 18 transports the fungus soil from the fertilizer box to the upper fertilizer box 25. The upper fertilizer box 25 is a rectangular metal box with a discharge port at the bottom. Below the discharge port is connected to the lower fertilizer box 23. The lower fertilizer box 23 is a rectangular metal box with a rectangular opening at the bottom. The opening is connected to the flap 30 via a hinge. The flap 30 is a rectangular steel plate. In the initial state, the flap drive motor 22 rotates forward, driving the flap 30 to close the opening of the lower fertilizer box 23. The fungus soil falls from the upper fertilizer box 25 into the lower fertilizer box 23 and accumulates on the flap 30. The quality sensor is installed on the outside of the bottom of the lower fertilizer box 23 via the sensor bracket 21. When the quality of the fungus soil reaches a preset value, it outputs a signal to the PLC controller. The PLC controller energizes the thrust electromagnet 20. Its push rod, via a pin, rotates baffle 24, a rectangular steel plate hinged at one end to the bottom edge of the discharge port of the upper fertilizer box 25. Baffle 24 rotates into the channel between the upper fertilizer box 25 and the lower fertilizer box 23, preventing the fungus soil from falling into the lower fertilizer box 23. Simultaneously, the flap drive motor 22 reverses, driving flap 30 to open the opening of the lower fertilizer box 23. Flap 30 pivots on its hinge, allowing fungus soil to fall from the lower fertilizer box 23 into the seed trench, covering the seeds. A photoelectric sensor detects when the seeds pass through the seed guide tube. The PLC controller controls the opening and closing timing of flap 30 based on the seed drop time and the distance between the exit of the lower fertilizer box 23 and the seed guide tube, ensuring that the fungus soil covers the seeds.

[0061] 4. Soil covering stage

[0062] As the device continues to advance, the soil covering component 2 begins to operate. This component is a height-adjustable structure consisting of two symmetrically arranged covering plates. These plates are rectangular steel plates with their bottom edges bent inward at a 30-degree angle. The tops of the plates are hinged to an adjustment rod, which is threaded into an adjustment sleeve, which is bolted to the center of the device frame. As the device advances, the covering plates' bottom edges come into contact with the soil on both sides of the seed trench. The covering plates push the soil inward, covering the spawning soil within the trench.

[0063] 5. Land stabilization stage

[0064] As the device continues to advance, suppression component 1 begins to operate. Suppression component 1 is a roller-like structure made of steel, with multiple rectangular protrusions evenly distributed along its circumference. Bearings support the roller shaft at each end, which is secured to the rear of the device frame via a bearing seat. As the roller advances, its bottom contacts the covered soil, and as it rotates, the protrusions compact the soil above the seed trench.

[0065] 6. Stop phase

[0066] During the operation of the device, the speed sensor and limit sensor in the control and drive component 6 are continuously tested. The speed sensor is installed next to the axle of the wheel 11 and is fixed by a sensor bracket. When it detects that the wheel 11 stops rotating, it outputs a signal to the PLC controller. The limit sensor is installed in the installation groove on the inner wall of the fertilizer box. When it detects that there is insufficient fungus soil in the fertilizer box, it outputs a signal to the PLC controller. After receiving the signal from the speed sensor or the limit sensor, the PLC controller controls the worm gear reduction motor 7 to stop rotating, the wheel 11 stops, and the device stops moving. At the same time, the PLC controller controls the drive motor 14, the auger drive motor 26 and the flap drive motor 22 to stop rotating, the seeding wheel 31, the auger 18 and the flap 30 stop moving, and the seeding and fungus soil discharge stop.
