Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a seed spreading machine for agricultural planting with a leveling function. Background Art

[0002] The history of seed drills can be traced back to ancient times. The earliest seeding tools were simple devices pulled by human or animal power. With the advent of the Industrial Revolution, mechanized seeding tools gradually developed into modern seed drills. In the working process of existing seed drills, in order to improve soil structure, increase soil fertility, create suitable seeding conditions, promote seed germination and ultimately increase crop yields, it is usually necessary to turn and level the soil before sowing. However, in the prior art, when there are hard lumps (such as hard soil lumps or hard stones) in the soil, turning and leveling can only break the hard soil lumps to a certain extent, while the hard stones are difficult to completely remove. If sowing is carried out without removing the hard stones, the stones in the soil will hinder the growth of the seed roots, thereby affecting the subsequent growth of the seeds and even leading to a reduction in yield.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0027] Studies have shown that when using existing technologies to turn and level the soil, if there are hard lumps (such as hard soil lumps or hard stones) in the soil, turning and leveling can only break up the hard soil lumps to a certain extent, while it is difficult to completely remove the hard stones. If sowing is carried out without removing the hard stones, the stones in the soil will hinder the growth of the seed roots, thereby affecting the subsequent growth of the seeds and even leading to a reduction in yield.

[0028] A sowing machine for agricultural planting with a leveling function, combined with Figure 1-Figure 3As shown, it includes: a seed drill 1, connected to an external traction device, and used for sowing crops; a leveling shell 2, arranged on the seed drill 1, and a transmission 3 is arranged on the leveling shell 2, and the input shaft of the transmission 3 is connected to the external traction device; a leveling mechanism is arranged in the leveling shell 2, and the leveling mechanism is used to discharge hard lumps in the soil and level the soil after the hard lumps are discharged; the leveling mechanism includes: a leveling piece 5 and a mirror-distributed debris removal piece 4; the leveling piece 5 and the mirror-distributed debris removal piece 4 are both rotatably connected to the leveling shell 2, and the debris removal piece 4 is connected to the transmission 3 Adjacent output shafts are fixedly connected, spiral plates are arranged on the mirror-distributed debris removal parts 4, spiral plates are arranged on the leveling parts 5, and transmission parts 6 are arranged on the leveling shell 2. The transmission parts 6 are used for transmitting power between the leveling parts 5 and the mirror-distributed debris removal parts 4. The leveling parts 5 cooperate with the mirror-distributed debris removal parts 4 to discharge and level the hard blocks in the soil; the soil pressing mechanism is arranged in the leveling shell 2, and is used to control the looseness of the soil; the collecting and crushing mechanism is arranged in the leveling shell 2, and is used to collect, distinguish and crush the hard blocks in the soil.

[0029] In the above scheme, the purpose is to export the hard lumps in the soil outward through the spiral plates on the mirror-distributed debris removal parts 4. A connection part connected to the external traction device is provided on the left side of the seeder 1. The transmission device 3 is used to transmit the power of the traction device to the mirror-distributed debris removal parts 4. The seeder 1 and the transmission device 3 are both existing devices and will not be elaborated on here. The debris removal parts 4 and the leveling parts 5 have the same rotation direction. The spiral plates on the debris removal parts 4 and the leveling parts 5 are both made of high-carbon steel, which ensures high hardness while controlling costs. The spiral plates on the debris removal parts 4 and the spiral plates on the same left and right directions on the leveling parts 5 have opposite rotation directions. The spiral plates on the debris removal parts 4 are used to discharge the hard lumps to the front and rear sides of the leveling shell 2, and the spiral plates on the leveling parts 5 are used to level the soil after the hard lumps are removed.

[0030] Working process: first, the soil is turned over, and then the device is used to level the soil. The user controls the traction device to drive the seeder 1, the leveling shell 2 and the parts thereon to move to the left together. The power of the traction device drives the mirror-distributed debris removal parts 4 to rotate together through the transmission device 3. The debris removal parts 4 drive the spiral plates thereon to rotate together, and the soil that is not flat after turning over is evenly divided and leveled from the middle to the front and rear sides. The hard lumps in the soil are also gradually moved to the front and rear sides driven by the spiral plates on the debris removal parts 4. Then the user collects the hard lumps through the collection and crushing mechanism, crushes the hard soil lumps in the hard lumps, and the hard lumps in the hard lumps are crushed. The stones are screened out and discharged to the front and rear sides of the leveling shell 2. Then, the leveling member 5, driven by the device, levels the soil after the hard blocks are removed. The soil crushed by the collection and crushing mechanism is gradually evenly divided and dispersed to the middle from the front and rear sides under the drive of the leveling member 5. At this time, the soil is leveled. During the soil leveling process, the user compacts the soil appropriately through the soil compacting mechanism to prevent the soil from being too loose and affecting the growth of seeds. After the soil is compacted appropriately, the traction device drives the seeder 1 to sow seeds in the leveled and compacted soil until all the soil is sown. At this time, the use of the device is completed.

[0031] Specific, combined Figure 2 and Figure 3 As shown, the soil compacting mechanism includes: a first soil compacting roller 7, which is rotatably connected to the leveling shell 2, and the leveling shell 2 is rotatably connected to the second soil compacting roller 8, and the first soil compacting roller 7 and the second soil compacting roller 8 cooperate to compact the soil twice. The leveling member 5 is located between the first soil compacting roller 7 and the second soil compacting roller 8, and the first soil compacting roller 7 is higher than the second soil compacting roller 8 in the vertical direction.

[0032] In the above scheme, the first soil-pressing roller 7 and the second soil-pressing roller 8 are used to compact the soil in steps and appropriately to prevent the soil from being too loose and affecting the growth of seeds. The first soil-pressing roller 7 is located between the debris removal component 4 and the leveling component 5, and is used to compact the soil after preliminary leveling. The second soil-pressing roller 8 is located on the right side of the leveling component, and is used to compact the leveled soil. The first soil-pressing roller 7 and the second soil-pressing roller 8 are both made of high-carbon steel to ensure hardness while controlling costs. The first soil-pressing roller 7 is higher than the second soil-pressing roller 8 to prevent the soil compaction degree from rebounding due to one-time compression.

[0033] Specific, combined Figure 2 and Figure 3 As shown, the collecting and crushing mechanism includes: mirror-distributed collecting shells 10, all fixedly connected to the leveling shell 2, and a plurality of through holes are arranged on the lower side of the collecting shell 10, which are used to filter the soil and intercept hard blocks; a crushing assembly is arranged in the leveling shell 2, and is used to crush the hard soil blocks in the hard blocks.

[0034] Specific, combined Figure 2-Figure 4As shown, the crushing assembly includes: a rotating shaft 11, which is rotatably connected in the leveling shell 2, the rotating shaft 11 is rotatably connected to the collecting shell 10 distributed in a mirror image, the rotating shaft 11 is connected to the transmission member 6, a plurality of crushing blades 12 are arranged on the rotating shaft 11, a movable fence 13 is rotatably connected in the collecting shell 10, a torsion spring is arranged between the movable fence 13 and the adjacent collecting shell 10, and the crushing blades 12 cooperate with the adjacent movable fence 13 to distinguish hard stones from hard soil blocks and crush the hard soil blocks.

[0035] In the above scheme, the purpose is to use the collecting shell 10 to collect the hard blocks, and then the crushing blades 12 and the movable fence 13 cooperate to crush the soil blocks in the hard blocks and screen out the stones. The lower side surface inside the collecting shell 10 is an arc that gradually tilts upward from left to right, which is used to guide the crushing of the hard blocks, and the lower side surface of the collecting shell 10 is provided with a plurality of through holes for screening the soil and hard blocks. The lower side of the collecting shell 10 is made of high manganese steel to ensure the wear resistance of the lower side of the collecting shell 10 and improve its service life. The crushing blades 12 and the adjacent movable fence 13 are also made of high manganese steel, so that when the two are subjected to strong impact, the surface is hardened and a wear-resistant layer is formed, and the high manganese steel has good toughness and is not easy to break.

[0036] Working process: When the hard blocks are discharged to the front and rear sides by the debris discharger 4, taking the front collecting shell 10 as an example, the device drives the collecting shell 10 to continue to move to the left. During this process, the collecting shell 10 scoops up the discharged hard blocks and part of the soil, and gradually moves to the lower side of the collecting shell 10. The soil moves downward to the ground through the through hole on the collecting shell 10. The rotating shaft 11 rotates under the drive of the transmission member 6, and the rotating shaft 11 drives the crushing blade 12 thereon to rotate clockwise (with the rotation of the rotating shaft 11 rotating clockwise). Figure 1 The movable fence 13 is moved to the right by the movable fence 13 and the movable fence 13 is reset under the drive of the torsion spring and the above operation is continued.

[0037] Further, combined with Figure 2 and Figure 6-Figure 8As shown, it also includes: equally spaced turning mechanisms, which are all arranged in the leveling shell 2, and are used to turn out stones buried in the soil. The turning mechanisms include: a fixed sleeve 15, which is arranged on the transmission member 6, and the fixed sleeve 15 is equipped with a distribution ring 16; a rotating shell 17, which is rotatably connected to the distribution ring 16, and the rotating shell 17 is equipped with a transmission sleeve 18. The fixed sleeve 15, the distribution ring 16, the rotating shell 17 and the transmission sleeve 18 together constitute a power transmission unit, and the rotating shell 17 is provided with a turning assembly for turning the soil and the stones therein.

[0038] Combination Figure 6-Figure 9 As shown, the turning assembly includes: circumferentially distributed sliding rods 19, circumferentially distributed chambers are provided on the rotating shell 17, the circumferentially distributed sliding rods 19 are respectively slidably connected to adjacent chambers on the rotating shell 17, elastic members are provided between the sliding rods 19 and the rotating shell 17, and the sliding rods 19 are fixedly connected to the soil turning blade 20; a plurality of limiter assemblies are equidistantly distributed and are all provided on the leveling shell 2, and are used to control the extension amount of the sliding rods 19. The rotating shell 17 is provided with a conversion groove 21 and a reset groove 22, the circumferentially distributed chambers on the rotating shell 17 are all connected and matched with the conversion groove 21 and the reset groove 22, the distribution ring 16 is fixedly connected with a storage capsule 23, the storage capsule 23 is connected with the reset groove 22, and the circumferentially distributed chambers on the rotating shell 17, the conversion groove 21, the reset groove 22 and the storage capsule 23 are all filled with transmission medium.

[0039] In the above scheme, the sliding rod 19 and the soil turning knife 20 are used to turn out the hard lumps inside the soil, wherein the two power transmission units on the front and rear sides cooperate with the fixed part and the transmission part of the adjacent transmission member 6, the fixed sleeve 15 and the distribution ring 16 are used to connect each power transmission unit and fix it with the fixed part of the transmission member 6, the rotating shell 17 and the transmission sleeve 18 cooperate with the adjacent transmission member 6 for driving the rotating shell 17 and the transmission sleeve 18 in the equidistantly distributed power transmission unit to rotate, and the modular installation facilitates subsequent maintenance or replacement, a rubber sealing ring is arranged on the outside of the sliding rod 19 to ensure the sealing sliding relationship between the rotating shell 17 and the sliding rod 19, the transmission medium in the conversion groove 21, the reset groove 22 and the storage bag 23 are all hydraulic oil, the storage bag 23 is made of elastic material, and the central angles of the conversion groove 21 and the reset groove 22 are both 90°.

[0040] Combination Figure 6-Figure 10As shown, the limiting assembly includes: an extrusion member 24, which is fixed in the leveling shell 2, and is provided with an array of extrusion parts 241, the rotating shell 17 is located between the mirror-distributed extrusion parts 241, and the sliding rod 19 is provided with a limiting part 191, and the limiting part 191 and the mirror-distributed extrusion parts 241 are both extrusion-matched. The rotating shell 17 is slidably connected with a circumferentially distributed limiting member 25, a spring is provided between the limiting member 25 and the adjacent rotating shell 17, and the limiting member 25 is limitedly matched with the sliding rod 19.

[0041] In the above scheme, the purpose is to use the limiting portion 191 and the extruding portion 241 to limit the extended length of the sliding rod 19, so as to ensure the turning effect of the soil-turning knife 20 on the hard block. The extruding portion 241 is crescent-shaped, and its upper side is an arc surface, and the center of the arc surface coincides with the rotation center of the rotating shell 17, so as to prevent the limiting portion 191 from being squeezed with the upper arc surface of the adjacent lower extruding portion 241. The limiting position of the limiting member 25 and the adjacent sliding rod 19 is hemispherical, which is used to limit the sliding rod 19 appropriately, and the limiting member 25 loses the limiting position on the adjacent sliding rod 19 only when the sliding rod 19 is affected by external factors, and the force of the elastic member between the sliding rod 19 and the rotating shell 17 is difficult to release the limiting position of the adjacent sliding rod 19 by the limiting member 25.

[0042] Working process: when the user controls the device to perform soil turning and leveling, taking the front power transmission unit as an example, the transmission member 6 drives the transmission sleeve 18 to rotate, the transmission sleeve 18 drives the rotating shell 17 to rotate, and the rotating shell 17 drives the sliding rod 19 distributed in the circumferential array on it to rotate. In this process, after the sliding rod 19 rotates to the lower side, if the hard block is located on the upper side of the soil turning knife 20, the sliding rod 19 drives the soil turning knife 20 to rotate counterclockwise and turn the hard block out. If the hard block is located on the lower side of the soil turning knife 20, when the soil turning knife 20 contacts the hard block, the hard block squeezes the soil turning knife 20 to move upward, and the soil turning knife 20 drives the sliding rod 19 to move upward. The sliding rod 19 loses the limiting state between the adjacent limiting member 25, and at the same time squeezes the elastic member between the sliding rod 19 and the rotating shell 17. The hydraulic oil in the adjacent chamber of the sliding rod 19 is squeezed into the adjacent chamber of the left sliding rod 19 through the conversion groove 21, and at the same time stretches the left sliding rod 19 and the rotating shell 17. The elastic member of the left sliding rod 19 (even if the left sliding rod 19 and the tiller 20 extend outward), at this time, the limit member 25 adjacent to the left sliding rod 19 loses the limit on the left sliding rod 19, and as the rotating shell 17 continues to rotate, the lower sliding rod 19 rotates to the right half of the rotating shell 17, and the adjacent chamber of the lower sliding rod 19 loses the connection relationship with the conversion groove 21, and the left sliding rod 19 rotates to the lower extrusion portion 241. Because the left sliding rod 19 previously drove the limit portion 191 to extend outward, at this time, the limit portion 191 and the lower side of the lower extrusion portion 241 are squeezed, and the sliding rod 19 is driven to continue to extend outward, and at this time, the hydraulic oil in the sliding rod 19 located on its left side is extracted through the conversion groove 21 into the sliding rod 19 located on the lower side, thereby ensuring that the sliding rod 19 is always in an extended state during the tillage process, ensuring the effect of turning out the hard lumps in the soil, and at this time, the sliding rods 19 on the left and right sides of the extended sliding rod 19 are both in a retracted state.

[0043] As the extended sliding rod 19 and the retracted sliding rods 19 on both sides rotate to the reset groove 22, the elastic member between the retracted sliding rod 19 and the rotating shell 17 drives the sliding rod 19 to reset, and the hydraulic oil in the storage bag 23 is extracted through the reset groove 22. When the extended sliding rod 19 moves to the reset groove 22, the elastic member between the extended sliding rod 19 and the rotating shell 17 drives the extended sliding rod 19 to reset. At the same time, the lower side of the upper extrusion part 241 and the limiting part 191 of the extended sliding rod 19 are squeezed and assist the extended sliding rod 19 to reset. After the sliding rod 19 is reset, the limiting member 25 limits the adjacent sliding rod 19, and the hydraulic oil flows into the storage bag 23 through the reset groove 22. This is the single-circuit working process of the device.

[0044] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
