[0003] The existing corn rotary tillage and seeding machine has the problem of clumping in the soil after rotary tillage. These hard clumps seriously interfere with the normal operation of the furrow opener. During the furrowing process, the furrow opener is difficult to stabilize the furrow, resulting in uneven seeding furrow depth, which directly leads to uneven seed soil thickness and uneven seed burial depth. Shallow seeds are often eaten by birds due to easy exposure to the ground surface, and water loss is fast in dry environments, resulting in a significant reduction in seedling emergence rate. Deep seeds face the difficulties of large breaking resistance and difficulty in successfully emerging from the soil, and even rot due to lack of oxygen and high humidity, which seriously affects the seeding quality and final emergence rate of corn. Therefore, a corn rotary tillage and seeding machine is provided to solve the above problems. SUMMARY

[0013] Compared with the prior art, the present application has the following advantages: 1. By setting the cooperation of the first motor and other parts, the rack rotates the seeding land, and then seeds the corn on the rotary seeding land. Before seeding, the staff starts the first motor and the second motor, then drives the first straight gear to rotate through the first motor, thereby driving the second straight gear to rotate through the first connecting plate and the rotating plate. At this time, the rotating plate drives the multiple connecting rotating plates on the outer wall to rotate, and the scraper at the bottom of the connecting rotating plate can scrape the rotary seeding land. After the rotary operation, there may be soil ridges, pits or large pieces of soil on the ground. The scraper can push the raised soil pile and fill the shallow depression through the continuous scraping effect of the circumferential rotation, thereby improving the flatness of the ground surface, ensuring the subsequent stable ditching of the furrow opener, and making the seeding depth consistent to provide favorable conditions for the subsequent seed growth; 2. By setting the crushing components, the two groups of hitting blocks can continuously and staggeringly hit the seeding land, avoiding the formation of a crushing blind area, thereby forming a continuous cycle of "hitting-scraping-hitting" to ensure the stability of the subsequent ditching depth and width. The loose and uniform soil can make the furrow opener form a regular V-shaped or U-shaped ditch, avoid the unevenness of the ditch wall caused by soil clumping, lay the foundation for the accurate seed delivery in the subsequent seeding channel, and further ensure the uniformity of the subsequent seeding depth, avoid the uneven distribution of seeds caused by the unevenness of the ground surface, and the two groups of hitting blocks inside the scraper can significantly improve the degree of fine soil crushing, soil uniformity and soil conservation capacity, especially in soil crushing, mixing and soil conservation, thereby improving the applicability of the equipment; 3. By setting the pressure reducing mechanism, when the scraper finishes covering the soil, the hitting block moves above the seeding ditch. When the hitting block hits the ground, the abutting end of the second spherical rod will first abut against the inclined surface of the first abutting block. Under the action of the first abutting block inclined surface, each hitting block is separated from the ground. When the second spherical rod moves from any point on the first abutting block inclined surface to the highest point and the second spherical rod is separated from the first abutting block through the driving of the connecting rotating plate, then under the action of the second spring, the hitting block hits and flattens the soil covering the corn seeds, compacts the top of the soil after covering, thereby making the soil after covering form an upper-pressing and lower-loosening state, forming an anti-erosion protection for the soil above the seeds, avoiding the erosion and loss of loose soil caused by rainwater, providing a favorable environment for the subsequent seed growth, and making the seed germination depth consistent without the problem of uneven burial depth; 4. By setting up components such as conical blocks, the auxiliary rotating plate can drive multiple conical blocks at the bottom to push outwards the straw residue, weeds and other debris on the soil surface at the front of the furrow opener, thereby removing them from the sowing position. When the first bevel gear separates from the helical gear, the auxiliary rotating plate returns to its original position under the action of the torsion spring. Then, when the first bevel gear and the helical gear mesh again, the auxiliary rotating plate rotates again. This reciprocating swing prevents debris from clogging the furrow opener or covering the sowing furrow, reduces missed sowing and seed jamming, ensures that corn seeds can directly contact the soil, and improves the germination rate. 5. By setting up the cooperation of components such as the first spherical rod, when the auxiliary rotating plate moves the debris, the first spherical rod abuts against the inclined surface of the arc-shaped abutment block. As the auxiliary rotating plate rotates, it drives the first spherical rod to move from the highest point to the lowest point of the arc-shaped abutment block. At the same time, the arc-shaped abutment block pushes the first spherical rod to drive the second connecting plate to move downward. The second connecting plate then drives the scraper to scrape the debris on the conical block, separating the debris from the conical block. This prevents the conical block from losing its ability to move due to the accumulation of debris, ensuring the continuity of subsequent cleaning operations. Attached Figure Description

[0018] The inner side of the rack 1 is provided with a rotary tillage device for land, since the rotary tillage of the seeding land is prior art, therefore, the present scheme is not described in detail. The seeding device 3 is how to seed is the prior art, so the present scheme does not make too much repetition; The present scheme mainly solves the problem that the soil after rotary tillage is generally clumped. These hard clumps will seriously interfere with the normal operation of the furrow opener. During the furrow opening process, the furrow opener is difficult to stably dig a furrow, resulting in uneven seeding furrow depth, which directly leads to uneven seed covering thickness and uneven seed burial depth. The specific implementation process is as follows: Please refer to Figures 1-10 The embodiment provides a corn rotary tillage seeder, which comprises a rack 1, a plurality of storage boxes 2 are installed at one end of the rack 1, a seeding device 3 is installed at the bottom of each storage box 2, a seeding channel 5 is installed at the bottom of the seeding device 3, the storage box 2 transports corn seeds to the inside of the seeding channel 5 through the seeding device 3, a furrow opener 23 is fixedly connected to the outer wall of the seeding channel 5, a scraping unit, a pressure reducing mechanism and an auxiliary cleaning piece are arranged outside the seeding channel 5, the scraping unit comprises a plurality of first motors 7 fixedly connected to the bottom of the rack 1, each first motor 7 is correspondingly arranged on one side of one storage box 2, a first spur gear 8 is fixedly connected to the executing end of each first motor 7, a second spur gear 9 is engaged on one side of the first spur gear 8, the second spur gear 9 is rotatably connected to the outer wall of the seeding channel 5, a plurality of first connecting plates 10 are fixedly connected to the bottom of the second spur gear 9, a rotating plate 12 is fixedly connected to the bottom of the first connecting plates 10, a plurality of connecting rotating plates 6 are fixedly connected to the outer wall of the rotating plate 12, a scraper 19 is arranged on one side of each connecting rotating plate 6, and the lowest point of the furrow opener 23 is lower than the lowest point of the scraper 19. Firstly, the staff fixes the connecting end of the tractor and the rack 1 through the bolt assembly, then the staff drives the tractor to move the rack 1, rotates and tills the seeding land through the rack 1, and then seeds corn on the rotary tilled seeding land. Before seeding, the staff starts the first motor 7 and the second motor 27, then drives the first spur gear 8 to rotate through the first motor 7, so as to drive the second spur gear 9 to rotate the rotating plate 12 through the first connecting plate 10. At this time, the rotating plate 12 drives the plurality of connecting rotating plates 6 on the outer wall to rotate. At this time, the scraper 19 at the bottom of the connecting rotating plate 6 scrapes the rotary tilled seeding land. After rotary tillage, there may be soil ridges, pits or large pieces of soil on the ground. The scraper 19 can push the raised soil pile and fill the shallow depression through the continuous scraping effect of the circumferential rotation, so as to improve the flatness of the ground surface. Please refer to Figures 2-7The side wall of the scraper 19 is provided with a crushing component for crushing the sowed land after the rotary tillage. The crushing component comprises a second motor 27 fixedly connected to the outer wall of the scraper 19, two third shaft rods 33 rotatably connected to the inner side of the scraper 19, one end of the second motor 27 penetrating into the interior of the scraper 19 and being fixedly connected to one of the third shaft rods 33, and one synchronous wheel 37 fixedly connected to the outer wall of each of the third shaft rods 33. The outer walls of the two synchronous wheels 37 are engaged with a synchronous belt 32. The crushing component further comprises two groups of beating blocks 20 arranged on one side of the scraper 19, and each adjacent beating block 20 is arranged staggeredly. One end of each beating block 20 is fixedly connected with a trapezoidal block 35, and the inner side of the scraper 19 is provided with a trapezoidal groove 38 matched with the trapezoidal block 35. The trapezoidal block 35 is slidably connected with the scraper 19 through the trapezoidal groove 38. A second spring 39 is arranged between the trapezoidal block 35 and the trapezoidal groove 38. The top of each of the three beating blocks 20 in each group is fixedly connected with a rectangular rod 41, and the top of the other beating block 20 is fixedly connected with a straight rack 30. One end of each of the two third shaft rods 33 is fixedly connected with a third spur gear 31 engaged with the straight rack 30. Each straight rack 30 and each of the three rectangular rods 41 are fixedly connected through an auxiliary rod 36. Only one third of the meshing teeth of the third spur gear 31 is engaged. The initial bottom of one of the two groups of beating blocks 20 is flush with the bottom of the scraper 19. When the scraper 19 is scraped on the seeding ground, the second motor 27 drives the third shaft rod 33 to rotate and drives the synchronous wheel 37 to rotate, so as to drive another synchronous wheel 37 on the left to rotate through the synchronous belt 32, and then the two third spur gears 31 rotate at the same time, when one of the third spur gears 31 is separated from one of the straight racks 30, a group of beating blocks 20 is pushed to move towards the ground under the action of a group of second springs 39 to beat the seeding ground after rotary tillage, when a group of beating blocks 20 is beaten, the other third spur gear 31 is engaged with the other straight rack 30 to drive another group of beating blocks 20 to move upwards, in this process, the group of beating blocks 20 that has been beaten is scraped on the ground, and only when the other third spur gear 31 is separated from the other straight rack 30, the scraped group of beating blocks 20 is driven to move upwards, so that the two groups of beating blocks 20 can continuously stagger beat the seeding ground, avoid the broken blind area, and form a continuous cycle of "beating-scraping-beating", so as to ensure the stability of the subsequent furrowing depth and width, and the loose and uniform soil can make the furrower form a regular V-shaped or U-shaped furrow, avoid the uneven furrow wall caused by soil clumping, lay a foundation for the subsequent seed precision delivery in the seeding channel, and then ensure the uniformity of the subsequent seeding depth, avoid the uneven distribution of seeds caused by the surface undulation, and the two groups of beating blocks 20 are additionally arranged in the inner side of the scraper 19, which can significantly improve the fine degree of soil crushing, soil uniformity and soil conservation capacity, especially in soil crushing, mixing and soil conservation, thereby improving the applicability of the equipment.

[0019] Please refer to Figures 8-9 The pressure reducing mechanism comprises a second spherical rod 29 fixedly connected at one end of each auxiliary rod 36, and a plurality of first abutting blocks 4 abutting against the second spherical rod 29 are fixedly connected to the outer wall of the seeding channel 5, and the first abutting blocks 4 are provided with inclined surfaces. After the furrower 23 furrows the seeding ground and the corn seeds are seeded into the seeding furrow through the storage box 2, the connecting rotating plate 6 drives the scraper 19 to rotate to the edge of the seeding furrow of the furrower 23, and when the connecting rotating plate 6 continues to drive the scraper 19 to rotate, the scraper 19 will dig the soil at the edge of the seeding furrow into the seeding furrow, so as to achieve the effect of covering the corn seeds, and the design combines the post-seeding process through the covering function of the scraper 19, thereby improving the efficiency of seeding; When the scraper 19 finishes covering the soil, the hitting block 20 moves above the seeding trench. When the hitting block 20 hits the ground, the abutting end of the second spherical rod 29 first abuts against the inclined surface of the first abutting block 4, and under the action of the inclined surface of the first abutting block 4, each hitting block 20 is separated from the ground. When the second spherical rod 29 moves from any point on the inclined surface of the first abutting block 4 to the highest point and is separated from the first abutting block 4 by the driving of the connecting rotating plate 6, then under the action of the second spring 39, the hitting block 20 hits and flattens the soil covering the corn seeds, compacts the top of the soil after covering, so that the soil after covering forms an upper-pressing and lower-loosening state, thereby forming erosion-resistant protection for the soil above the seeds, avoiding the collapse caused by the erosion and loss of loose soil by rainwater, providing a favorable environment for the subsequent growth of seeds, and making the seed germination depth consistent without the problem of uneven burial depth. Under the limitation of the inclined surface of the first abutting block 4, the impact stroke of the hitting block 20 is only the distance from the highest point to the lowest point of the first abutting block 4, so that the hitting block 20 weakens the hitting force on the seeding ground. If the force is too large, it may cause the soil in the seeding trench to be hard, which is not conducive to water retention and seedling emergence. This design completes the surface flattening and moderate compaction without damaging the loose structure of the covered soil and the safety of the seeds, thereby effectively avoiding excessive compaction and improving the seedling emergence quality. When the second spherical rod 29 is separated from the last first abutting block 4, the impact stroke of the hitting block 20 is restored, and the hitting block 20 continues to hit the seeding ground.

When the first bevel gear 13 moves to the back of the seeding channel 5, because the top of the annular plate 11 above the first abutting block 4 is not provided with the bevel gear 40, when the scraper 19 covers the seeding ditch, the auxiliary rotating plate 18 will not rotate, avoiding the influence of the scraper 19 on the covering; When the auxiliary rotating plate 18 stirs the sundries, the first spherical rod 28 is in abutment with the inclined surface of the arc-shaped abutting block 15, and when the auxiliary rotating plate 18 rotates, the first spherical rod 28 is driven to move from the highest point to the lowest point of the arc-shaped abutting block 15, and the first spherical rod 28 is pushed by the arc-shaped abutting block 15 to drive the second connecting plate 17 to move downward, and the sundries on the conical block 26 are scraped by the scraping plate 42 driven by the second connecting plate 17, so that the sundries are separated from the conical block 26, thereby avoiding the loss of the stirring ability of the conical block 26 due to the accumulation of the sundries, and ensuring the continuity of the subsequent cleaning operation; When the auxiliary rotating plate 18 rotates towards the scraper 19, the second connecting plate 17 is driven to move upward by the limiting slide rod 25 under the action of the first spring 34, so that the second connecting plate 17 can restore the initial state, so as to clean the sundries again when the auxiliary rotating plate 18 rotates next time.
