Description

Technical Field

[0001] This invention relates to the field of maize breeding, and in particular to a maize soil-borne disease resistance gene identification and inoculation device. Background Technology

[0002] Soil-borne diseases of maize refer to diseases spread by pathogens carried in the soil, mainly including head smut, head smut, and stalk rot. Because soil-borne diseases of maize have a significant impact on maize yield, in order to address this impact, thanks to technological advancements, technicians in related fields have conducted extensive breeding, optimization, and selection of maize seeds. Furthermore, to assess the resistance of newly bred varieties to soil-borne diseases, it is necessary to mix maize seeds with carriers of soil-borne diseases, inoculate them together, and sow them together, then observe and evaluate them during the maize's growth process.

[0003] In this process, the depth and spacing of corn planting, as well as the accuracy of the ratio of corn to soil-borne disease pathogens, will affect the accuracy of measuring and identifying the degree of resistance of corn seeds to soil-borne diseases. Therefore, the process of mixing and inoculating corn seeds and soil-borne disease carriers and planting them together is particularly important. As a result, technicians in related fields have optimized this process.

[0004] For a more accurate comparison, Chinese Patent CN115885623A discloses a sweet corn soil-borne disease resistance identification and inoculation device. In use, a wheel axle drives a drive rod to rotate, which in turn rotates a first and second distribution disc. The fungi and seeds are independently distributed and fall into a mixing chamber. After mixing, the fungi and seeds are planted in the soil. The rotation of the main wheel maintains a fixed spacing between the sweet corn seeds. A stirring rod is also included; the drive rod rotates a rotating rod, which in turn rotates a stirring rod at both ends inside the mixing chamber, mixing the fungi and seeds and improving the mixing effect.

[0005] By setting up a backfill plate and a compaction hammer, the backfill plate causes broken soil to re-cover the seeds. The drive rod drives the rotating rod to rotate, and the rotating rod drives the wheel to push the limit block, thereby pushing the L-shaped bracket to rotate upward. When the wheel rotates and disengages from the limit block, the L-shaped bracket will immediately rotate downward, and the compaction hammer will compact the soil, so that the soil covers the seeds. By setting up an opening and closing device, the rotating rod drives the control rod to rotate, and the control rod drives the incomplete gear to rotate, thereby driving the valve rod and the opening and closing device to rotate, so that the opening and closing device can intermittently open and close the seeding tube, which facilitates the mixing of seeds and fungi before they fall into the soil for planting.

[0006] However, the above-mentioned sweet corn soil-borne disease resistance identification and inoculation device has some shortcomings in actual use: 1. The failure to dig planting holes in the soil before sowing causes seeds and fungi to travel a greater distance after falling due to collisions with soil clods, thus reducing the accuracy of sowing corn seeds and fungi. 2. The mixing method of the above-mentioned mixing rod for fungi and seeds is relatively simple, resulting in poor mixing between corn seeds and fungi during mixing; furthermore, during the compaction of the soil by the tamping hammer, if the soil is too hard, it will damage the corn seeds, and soil compaction can also easily affect the subsequent growth process of corn seeds.

[0007] Therefore, based on the above-stated viewpoints, there is room for improvement in the existing technology for the mixed inoculation and co-sowing of maize seeds and soil-borne disease carriers. Summary of the Invention

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] I. The present invention facilitates traction with different types of external traction machinery through the traction mechanism. Compared with the prior art which requires manual pushing, it reduces the workload of workers and improves the speed of movement and the efficiency of sowing.

[0023] Second, the present invention can perform equal-depth and equal-spaced hole-making operations on the soil through the hole-making mechanism, so that the planting holes made by the hole-making mechanism can facilitate the falling of corn seeds and fungi. Compared with the prior art, it can minimize the problem of corn seeds and fungi being splashed and separated due to collision with hard soil clods when sowing corn seeds and fungi, thereby improving the accuracy of sowing corn seeds and fungi.

[0024] Furthermore, the hole-opening mechanism can be adjusted to change the depth and spacing of the planting holes, thereby improving the applicability of the hole-opening mechanism.

[0025] Third, the present invention can mix the fungi and seeds in more ways before sowing through the sowing mechanism. Compared with the single mixing method of the prior art, it can improve the mixing effect of fungi and seeds, thereby improving the inoculation effect of corn seeds.

[0026] Furthermore, if the fungal material is a viscous substance or has adsorption properties, existing technology cannot guarantee that all the fungal material and seeds can be discharged during the discharge process. However, when the receiving hopper rotates to the lower end, it will move downwards under the action of inertia and gravity. This process can effectively discharge the fungal material and seeds downwards, thereby improving the discharge efficiency.

[0027] Fourth, the present invention can cover an appropriate amount of soil on the planting hole after sowing by means of a soil covering mechanism. Compared with the prior art, on the one hand, it is less likely to damage the corn seeds, and on the other hand, it will not make the soil compacted, thus not affecting the subsequent growth process of the corn seeds. Furthermore, the amount of soil covered on the planting hole by the soil covering mechanism can be adjusted appropriately, thereby improving the applicability of the soil covering mechanism.

[0049] The following is in conjunction with the appendix Figures 1 to 12 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0050] This application discloses a corn soil-borne disease resistance gene identification and inoculation device. The device is primarily used during the inoculation and sowing of corn seeds with pathogens. Technically, it allows for the creation of planting holes of equal depth and spacing in the soil before inoculating and sowing corn seeds and pathogens. Especially during inoculation and sowing, it enables more thorough mixing of the pathogens and seeds, thereby improving the inoculation effect. Furthermore, after sowing, the invention can cover the planting holes with an appropriate amount of soil, further enhancing the efficiency and effectiveness of inoculation and sowing.

[0051] Example 1:

[0052] Reference Figure 1 and Figure 2 As shown, a corn soil-borne disease resistance gene identification and inoculation device includes a frame 1, rear wheels 10, an opening mechanism 2, a traction mechanism 3, and an inoculation mechanism 4. The frame 1 is a C-shaped structure with an opening at the left end. The rear wheels 10 are symmetrically arranged on the lower right side of the frame 1. The opening end of the frame 1 is sequentially provided with the opening mechanism 2 and the traction mechanism 3. The upper end of the frame 1 is provided with the inoculation mechanism 4, which is driven by the opening mechanism. During operation, the traction mechanism 3 needs to be connected to an external traction machine, and the traction mechanism 3 can be connected to different types of external machines.

[0053] Then, the external mechanical energy used for traction drives the hole-opening mechanism 2, the frame 1, the rear wheels 10, and the inoculation mechanism 4 to move through the traction mechanism 3. During this process, the hole-opening mechanism 2 can make holes at a fixed depth and spacing in the land, so that the inoculation mechanism 4 can be inoculated and mixed with the corn seeds and soil-borne pathogens under the drive of the hole-opening mechanism 2. Moreover, the inoculation mechanism 4 can also discharge the corn seeds mixed with soil-borne pathogens into the planting holes opened by the hole-opening mechanism 2 in a quantitative manner. After the corn seeds are planted, the resistance genes can be observed and identified during the subsequent growth of the corn.

[0054] Reference Figure 3 As shown, this is the traction mechanism 3 used in this application for connection with external traction machinery. Specifically, the traction mechanism 3 includes a frame 2 30, mounting side plates 31, wheel rods 32, front wheels 33, support vertical plates 34, connectors 35, reinforcing rod 1 36, and reinforcing rod 2 37. The frame 2 30 with a U-shaped structure is located on the left side of the opening mechanism 2. Mounting side plates 31 are symmetrically arranged at the lower end of the frame 2 30. Wheel rods 32 are arranged between the mounting side plates 31. Front wheels 33 are symmetrically arranged on the outer surface of the wheel rods 32. The front wheels 33 and the rear wheels 10 cooperate to support the frame 1 1, the frame 2 30, and the opening mechanism 2, and are also easy to be driven by external traction machinery.

[0055] A support vertical plate 34 is located at the upper end of the left middle of the frame 30. A connector 35 for connecting to the traction machinery is slidably disposed on the left side of the support vertical plate 34. Furthermore, when the height of the connection point on the external traction machinery is different, the height of the connector 35 can be adjusted so that the connector 35 can be connected to the external traction machinery after adjustment, thereby improving the applicability of the present invention. Reinforcing rods 36 connected to the frame 30 are symmetrically inclined on both sides of the support vertical plate 34. The reinforcing rods 36 can improve the stability and strength of the support vertical plate 34 during installation. A reinforcing rod 37 is also inclinedly disposed between the reinforcing rod 36 and the frame 30. The reinforcing rod 37 can improve the stability and strength of the reinforcing rod 36 during installation, so that the support vertical plate 34 will not deform due to large forces when subjected to traction.

[0056] Reference Figure 4 As shown, this is the hole-opening mechanism 2 used in this application for making planting holes at a fixed depth and spacing on the land. Specifically, the hole-opening mechanism 2 includes a sliding slot 11, a telescopic rod 20, a locking groove 12, a locking bolt 21, a limiting frame plate 22, an adjusting bolt 23, a supporting ring 24, a supporting rotating rod 25, a sprocket 26, a chain 27, and an insertion unit 28. The sliding slot 11 is symmetrically opened at the left end of the frame 1. The telescopic rod 20 is slidably arranged in the sliding slot 11. The locking groove 12 is evenly opened on the opposite side of the telescopic rod 20. The locking bolt 21 corresponding to the locking groove 12 is threaded through the left side of the sliding slot 11. When it is necessary to adjust the extension length of the telescopic rod 20, the locking bolt 21 must first be rotated so that it is no longer in the locking groove 12. Then the telescopic rod 20 can be adjusted. After the telescopic rod 20 is adjusted, the locking bolt 21 is rotated again so that it is in the corresponding locking groove 12 to fix the telescopic rod 20 again.

[0057] A limiting frame plate 22 is provided at the left end of the telescopic rod 20. The upper and lower ends of the limiting frame plate 22 are semi-circular structures. The left end of the limiting frame plate 22 is connected to the second frame 30. When the length of the extension sliding slot 11 of the telescopic rod 20 is adjusted, the telescopic rod 20 will drive the limiting frame plate 22 and the second frame to adjust. An adjusting bolt 23 is threaded through the upper end of the limiting frame plate 22. A support ring 24 located inside the corresponding limiting frame plate 22 is rotatably provided at the lower end of each adjusting bolt 23. A support rotating rod 25 is rotatably provided between the support rings 24. At the same time, rotating the adjusting bolts 23 on both sides can adjust the height of the support rings 24 and the support rotating rod 25. The limiting frame plate 22 can limit and guide the movement trajectory of the support rings 24 during adjustment.

[0058] The rear end of the support rod 25 passes through the corresponding support ring 24 and is equipped with a sprocket 26. The inoculation mechanism 4 is also equipped with a sprocket 26. A chain 27 is arranged between the sprockets 26. The outer side of the middle part of the support rod 25 is equipped with an insertion unit 28 for drilling holes in the soil during rotation. During operation, the height of the support ring 24 needs to be adjusted according to the depth of the hole, so that the hole-drilling rod 282 located at the lower end and in a vertical state can be inserted into the soil to a certain depth when it moves with the traction mechanism 3. Since the angle between adjacent hole-drilling rods 282 is consistent, when the length of the hole-drilling rod 282 extending out of the corresponding sliding rod groove 281 is constant, the distance between the planting holes inserted by the hole-drilling rod 282 in the soil will also be approximately the same, thereby achieving the function of drilling planting holes at a fixed depth and distance.

[0059] Reference Figure 5 As shown, this is the insertion unit 28 in this application; specifically, the insertion unit 28 includes a limiting circular plate 280, a sliding rod groove 281, an opening rod 282, a connecting through groove 283, an adjusting rod 284, and an adjusting component 29. The symmetrically distributed limiting circular plates 280 are sleeved on the middle of the supporting rotating rod 25. The sliding rod grooves 281 are evenly distributed in a ring between the limiting circular plates 280. The opening rods 282 are slidably arranged in the sliding rod grooves 281. The end of the opening rod 282 away from the limiting circular plate 280 is a conical structure so that the opening rod 282 can be inserted into the soil to make a planting hole. The front limiting circular plate 280 is evenly provided with connecting through grooves 283 that communicate with the sliding rod grooves 281.

[0060] Adjusting rods 284, which are connected to corresponding perforation rods 282, are slidably disposed within the connecting grooves 283. Adjusting components 29 are disposed between the adjusting rods 284. The adjusting components 29 can simultaneously adjust the distance of all perforation rods 282 extending out of the sliding rod grooves 281. The spacing of the planting holes inserted into the soil by the adjusted perforation rods 282 will also be adjusted accordingly, thereby improving the applicability of the present invention. Furthermore, the adjusting components 29 can also fix the adjusted perforation rods 282, so that the adjusted perforation rods 282 can still stably perform perforation operations on the soil.

[0061] Continue to refer to Figure 5As shown, this is the adjustment assembly 29 used in this application to simultaneously adjust all the perforated rods 282. Specifically, the adjustment assembly 29 includes an adjustment frame 290, an arc-shaped through groove 291, an anti-detachment block 292, a connecting bolt 293, and a connecting groove 294. The adjustment frame 290 is rotatably mounted on the outer surface of the support rotating rod 25 and located at the front end of the limiting circular plate 280. The adjustment frame 290 is evenly provided with annularly distributed arc-shaped through grooves 291. The front ends of the adjustment rods 284 all pass through the corresponding arc-shaped through grooves 291 and are provided with anti-detachment blocks 292. When the adjustment frame 290 is rotated, the adjustment rods 284 will slide in the connecting groove 283 under the limiting and guiding of the arc-shaped through grooves 291, so that the adjustment rods 284 can drive the perforated rods 282 to extend and retract in the corresponding sliding rod grooves 281. This method improves the efficiency of adjusting the perforated rods 282, while the anti-detachment block 292 can prevent the adjustment frame 290 from detaching from the adjustment rods 284.

[0062] The adjusting frame 290 is threaded with connecting bolts 293 for connecting to the adjusting rod 284. The outer side of the supporting rotating rod 25 is evenly provided with connecting grooves 294 corresponding to the connecting bolts 293. The connecting bolts 293 and the connecting grooves 294 cooperate to fix the adjusting frame 290 to the supporting rotating rod 25, so that the adjusted adjusting frame 290 will not rotate. In addition, the adjusting rod 284 can also fix the hole-opening rod 282, so that the adjusted hole-opening rod 282 can perform hole-opening operations more stably.

The lower end of the storage cylinder 41 has a funnel-shaped structure. The storage cylinder 41 is provided with a partition plate 410 inside. The connecting ring 43 can improve the stability of the cylinder installation. The storage cylinder 41 is used to store the carrier of corn seeds and soil-borne pathogens. The partition plate 410 can separate the corn seeds and the pathogens.

[0065] The upper end of the storage cylinder 41 is hinged with a cover plate 42 for sealing it. The cover plate 42 can also prevent the seeds and fungi in the storage cylinder 41 from falling out of the storage cylinder 41 due to bumps during the journey. The lower end of the cover plate 42 is provided with a sealing ring 420. The sealing ring 420 can improve the sealing degree when the cover plate 42 seals the upper end of the storage cylinder 41, and can also reduce the impact of the cover plate 42 shaking on the storage cylinder 41 due to bumps. The lower end of the storage cylinder 41 is provided with a connecting ring 43 with openings at the upper and lower ends and a support ring 44 with openings at the front and rear ends. The opening in the middle of the connecting ring 43 corresponds to the opening at the lower end of the storage cylinder 41. The upper and lower ends of the support ring 44 are also provided with discharge channels corresponding to the openings in the middle of the connecting ring 43. Limiting rings 440 are provided at both ends of the support ring 44.

[0066] A discharge disc 45 is rotatably mounted on the inner side of the support ring 44, and a limiting ring 440 can limit the discharge disc 45. A support rod 46 is rotatably connected to the corresponding support frame 40 on the rear side of the discharge disc 45. The support rod 46 is connected to the sprocket 26, so that the support rotating rod 25 can drive the discharge disc 45 to rotate under the drive of the opening mechanism 2. At least four metering grooves 450 are evenly distributed in a ring on the outer surface of the discharge disc 45. The metering grooves 450 have a conical structure and the opening corresponds to the inner diameter of the connecting ring 43.

[0067] When the corn seeds and fungi in the storage cylinder 41 fall downward from the opening at the bottom of the storage cylinder 41, they can pass through the discharge channel on the upper side of the connecting ring 43 and the support ring 44 in sequence and fall into the metering tank 450. The corn seeds and fungi in the metering tank 450 can then be mixed and inoculated. Furthermore, when the opening mechanism 2 indirectly drives the discharge disc 45 to rotate, it will cause the corn seeds and fungi to rotate to the lower end and pass through the discharge channel on the lower side of the support ring 44 to be discharged downward, thereby realizing the quantitative inoculation and quantitative discharge of corn seeds and fungi.

[0068] The lower end of the support ring 44 is provided with a discharge hopper 47 located outside the discharge channel and connected to the support frame 40. The discharge hopper 47 can limit and guide the discharge process of corn seeds and fungi, so that the corn seeds and fungi can fall more accurately into the planting hole opened by the opening mechanism 2. A cross-shaped installation channel 451 is opened between the metering channels 450. Each metering channel 450 is provided with a corresponding receiving hopper 452. The receiving hopper 452 is used to receive the corn seeds and fungi that fall into the metering channel 450.

[0069] Example 3:

[0070] Reference Figures 9 to 11As shown in Embodiment 2, it can be seen from the above-disclosed technical solution that when the corn seeds and fungi fall into the upper receiving hopper 452, they are not further stirred and mixed. Therefore, the effect of fungi inoculating corn seeds with pathogens is relatively poor. In order to improve the effect of fungi inoculating corn seeds with pathogens, a transmission unit 48 located in the installation channel 451 is set between the receiving hoppers 452. Specifically, the transmission unit 48 includes a connecting sleeve rod 480, a movable channel 453, a connecting through rod 481, a limiting collar 482, a stirring support rod 483, a gear groove 454, a connecting rod 484, an internal gear 485, a gear rod 486, a transmission gear 487, a tooth groove 488, and a linkage component 49.

[0071] Vertically distributed connecting sleeve rods 480 are set in and fit against the mounting through groove 451. The connecting sleeve rods 480 and the mounting through groove 451 are provided with movable through grooves 453 perpendicular to the connecting sleeve rods 480. A connecting through rod 481 is provided in the movable through groove 453. Limiting rings 482 are provided at both ends of the connecting through rod 481 and both ends of the connecting sleeve rod 480. A stirring support rod 483 is rotatably arranged in the limiting ring 482. The end of the stirring support rod 483 away from the limiting ring 482 is rotatably connected to the corresponding receiving hopper 452.

[0072] As shown in the figure, when the connecting sleeve rod 480 is in a vertical state, the receiving hopper 452, which receives corn seeds and fungi at its upper end, will move downwards via the stirring support rod 483 and the limiting collar 482 connected to it. During this process, the connecting sleeve rod 480 can slide within the movable channel 453, thus not affecting the movement trajectory of the connecting sleeve rod 480. Furthermore, the downward movement of the receiving hopper 452 at its lower end can more effectively discharge the corn seeds and fungi inside. Similarly, when the connecting rod 481 is in a vertical state, the connecting rod 481 can also move downwards within the movable channel 453, thereby achieving the above effects and improving the discharge efficiency.

[0073] In order to drive the corn seeds and fungi in the receiving hopper 452 to rotate and mix, thereby improving the effect of inoculating the corn seeds with pathogens, gear grooves 454 are opened on both sides of the quantitative trough 450. Connecting rods 484 are evenly arranged on both sides of the receiving hopper 452. The corresponding connecting rods 484 are slidably arranged with an internal gear 485 located in the gear groove 454 between the ends away from the receiving hopper 452. A gear rod 486 is also rotatably arranged in the gear groove 454. A transmission gear 487 that meshes with the corresponding internal gear 485 is provided on the outer surface of the gear rod 486. Gear grooves 488 that mesh with the corresponding transmission gear 487 are evenly opened on the outer surface of the stirring support rod 483. A linkage component 49 that passes through the discharge circular plate 45 and is located in front of it is also provided between the internal gears 485.

[0074] The linkage component 49 can drive the internal gear 485 located at the upper end to rotate. When the internal gear 485 rotates, it can drive the corresponding receiving bucket 452 to rotate through the connecting rod 484 connected to it. When the internal gear 485 rotates, it can also drive the stirring rod 483 to rotate through the corresponding transmission gear 487 and tooth groove 488. Furthermore, the stirring rod 483 rotates in the opposite direction to the corresponding internal gear 485, so the receiving bucket 452 and the stirring rod 483 also rotate in opposite directions. During the process of the receiving bucket 452 and the stirring rod 483 rotating in opposite directions, they can play a role in driving the corn seeds and fungi to mix thoroughly.

[0075] Reference Figure 10 and Figure 11 As shown, this is the linkage component 49 in this application; specifically, the linkage component 49 includes a transmission slot 455, a rectangular block 490, a support front rod 491, a driven wheel rod 492, a pulley 493, a transmission belt 494, a driven gear 495, a driving gear 496, a gear rod 497, a support block 498, a reset spring rod 499, a rotating motor 4910, a magnet block 4911, and a magnet strip 4912. The transmission slot 455, corresponding to the internal gear 485, is opened on the front side of the discharge circular plate 45. A rectangular block 490 is provided in the middle of the front end of the discharge circular plate 45. A support front rod 491, which is rotatably connected to the corresponding support frame 40, is provided at the front end of the rectangular block 490. The support front rod 491 can support the discharge circular plate 45 through the rectangular block 490, thereby improving the stability of the discharge circular plate 45 during installation.

[0076] A driven wheel rod 492 is rotatably mounted on the side of the rectangular block 490 corresponding to the transmission slot 455. A pulley 493 corresponding to the transmission slot 455 is mounted on the outer side of the driven wheel rod 492. A transmission belt 494 is provided between the pulley 493 and the corresponding internal gear 485. When an external force drives the driven wheel rod 492 at the upper end to rotate, the driven wheel rod 492 can drive the corresponding internal gear 485 to rotate through the pulley 493 and the transmission belt 494 connected to it, thereby driving the receiving bucket 452 and the stirring rod 483 to rotate in the opposite direction.

[0077] To facilitate the rotation of the driven wheel rod 492 at the upper end, a driven gear 495 is sleeved on the opposite side of the driven wheel rod 492. The front end of the driven gear 495 meshes with the driving gear 496. A gear rod 497 is provided in the middle of the driving gear 496. A support block 498 is rotatably provided at the upper end of the gear rod 497. A reset spring rod 499 connected to the corresponding support frame 40 is provided on the front side of the support block 498. The reset spring rod 499 can always provide a forward force for the support block 498, the gear rod 497 and the driving gear 496. A rotary motor 4910 is provided at the upper end of the support block 498 through a motor base. The output shaft of the rotary motor 4910 is connected to the upper end of the gear rod 497. The rotation of the output shaft of the rotary motor 4910 can drive the driving gear 496 to rotate through the gear rod 497.

[0078] A magnet block 4911 is provided on the side of the support block 498 near the discharge circular plate 45. Magnet strips 4912 corresponding to the driven gear 495 are evenly arranged at the front end of the discharge circular plate 45. The magnet strips 4912 at the upper end can magnetically attract the magnet block 4911, and the attraction between the magnet strips 4912 and the magnet block 4911 is greater than the tension of the reset spring rod. This allows the magnet block 4911 to drive the support block 498, gear rod 497, drive gear 496 and rotating motor 4910 to move backward. This allows the drive gear 496 to mesh with the driven gear 495 at the upper end, so that the driven gear 495 at the upper end can indirectly drive the internal gear 485 at the upper end to rotate.

[0079] When the driven gear 495 at the upper end rotates along the support rod 46, the magnet block 4911 and the magnet strip 4912 will separate. The magnet block 4911, the support block 498, the gear rod 497, the driving gear 496 and the rotating motor 4910 can move forward and reset under the pulling force of the reset spring rod 499, so as not to affect the subsequent rotation process of the other driven gears 495.

[0080] Example 4:

[0081] Reference Figure 12As shown in Example 3, and through the technical solution disclosed above, it can be seen that when corn seeds and fungi fall into the planting hole, the planting hole is not covered with soil. Therefore, in order to cover the planting hole with soil, a soil covering mechanism 5 is set up to cover the top of the seeds with soil. Specifically, the soil covering mechanism 5 includes a support crossbar 50, a lifting bolt 51, a driven connecting plate 52, an adjusting vertical rod 53, an incomplete gear 54, a circular through groove 55, a locking bolt 56, and a soil covering inclined plate 57. The support crossbar 50 is set inside the frame 1 and is located on the right side of the discharge hopper 47. The lifting bolt 51 is threaded through the middle of the support crossbar 50. The driven connecting plate 52 located at the upper end of the support crossbar 50 is rotatably set at the upper end of the lifting bolt 51. Rotating the lifting bolt 51 can drive the driven connecting plate 52 to move up and down for adjustment.

[0082] Adjustable vertical rods 53 are provided on both sides of the driven connecting plate 52, which slide through the supporting crossbar 50. The adjustable vertical rods 53 can be adjusted up and down together with the driven connecting plate 52. The upper end of the adjustable vertical rod 53 passes through the driven connecting plate 52 and is provided with intermeshing incomplete gears 54. Rotating one side of the incomplete gear 54 can drive the other side of the incomplete gear 54 to rotate together, so that the incomplete gear 54 can drive the adjusting vertical rod 53 to rotate in the opposite direction. One side of the incomplete gear 54 is provided with evenly spaced circular through slots 55. The upper middle part of the driven connecting plate 52 is provided with a locking bolt 56 located in the corresponding circular through slot 55 by means of thread engagement. The locking bolt 56 can fix the incomplete gear 54 through the circular through slot 55, so that the adjusting vertical rod 53 no longer rotates.

[0083] The lower end of the adjusting vertical rod 53 is provided with a soil-covering inclined plate 57. The soil-covering inclined plate 57 is symmetrically distributed and its right end is inclined to the opposite side. When the soil-covering inclined plate 57 is inserted into the soil, the inclination direction of the soil-covering inclined plate 57 can guide the soil towards the planting hole, so that the upper end of the planting hole can be covered by soil. In addition, the inclination angle of the soil-covering inclined plate 57 can be indirectly adjusted through the incomplete gear 54 according to the usage requirements, so that the amount of soil turned by the soil-covering inclined plate 57 can be adjusted. The soil-covering inclined plate 57 can also be indirectly adjusted up and down through the lifting bolt 51, so that the depth of soil turning by the soil-covering inclined plate 57 can be adjusted, thereby improving the applicability of the present invention.

[0084] During operation: First, the device is connected to an external traction machine via the traction mechanism 3, and the external traction machine moves the device to the land to be sown. Then, the hole-opening mechanism 2 is adjusted according to the usage requirements so that the hole-opening mechanism 2 can open planting holes of the required depth and spacing. Next, the soil-covering mechanism 5 is adjusted to adapt to the situation, and the soil-covering inclined plate 57 can be adjusted to an appropriate tilt angle and height. Then, appropriate amounts of corn seeds and carriers of soil-borne pathogens are placed on both sides of the partition plate 410 in the storage cylinder 41.

[0085] Step 2: The device is moved by an external traction machine, so that the opening mechanism 2 can make openings at equal depths and intervals on the ground during the movement. Meanwhile, the inoculation mechanism 4 can quantitatively discharge corn seeds and fungi into the planting holes while being driven by the opening mechanism 2. Furthermore, the corn seeds and fungi can be thoroughly mixed before being discharged, thereby improving the effect of inoculating corn seeds with pathogens.

[0086] Step 3: The soil covering mechanism 5 can cover the corn seeds and fungi located in the planting hole with an appropriate amount of soil while moving with the external traction machinery, thereby covering the corn seeds and fungi and improving the efficiency of planting corn seeds inoculated with pathogens.
