Description

Technical Field

[0001] The present invention relates to the technical field of deep plowing operations, and in particular to an intelligent crawler self-propelled deep plowing, soil crushing, stone removal and fertilization all-in-one machine. Background Art

[0002] Currently, cultivated land in some regions suffers from low soil organic matter content, poor physical structure, slow material circulation, and insufficient biological activity. Cultivated land maturation can improve soil structure, enhance aeration and water retention, and enhance soil fertility, thereby promoting crop growth and increasing yields. This process effectively improves soil aggregate structure, breaks down compacted layers, and optimizes soil porosity. Furthermore, through increased application of organic fertilizers and scientific farming practices, it accelerates nutrient cycling and activates soil microbial communities, fundamentally addressing the core issues hindering agricultural production, such as poor soil quality and weak soil activity.

[0003] Stones form hard barriers in the soil, reducing the porosity of the tillage layer and significantly reducing soil aeration and water permeability. For example, a survey of saline-alkali land in the North China Plain revealed that plots with high stone content had lower saturated hydraulic conductivity than those without stone, increasing the risk of root zone hypoxia. One goal of maturation is to create a "loose top and firm bottom" tillage layer structure, but the presence of stones can lead to uneven soil looseness after tillage, affecting water infiltration and moisture retention.

[0004] Traditional stone removal machinery (such as bucket-type machines) uses a "complete excavation-screening-backfill" process, requiring the entire surface soil to be turned over, disrupting the original soil aggregate structure. This leads to a decrease in soil porosity, weakened water and fertilizer retention, and even exacerbated soil erosion. Mechanical vibrations in the screening mechanism and the operation of the conveyor belt result in significant energy losses, resulting in high operating costs. Furthermore, during soil maturation, fertilizer application is often required to improve the deep soil structure, balance nutrient distribution, and optimize the root growth environment. During the insertion of fertilizer pipes into the soil, especially in heavy clay soils, the surrounding soil is squeezed and compacted, allowing fine soil particles to easily enter the fertilizer outlet holes or internal channels of the pipes, causing blockage and hindering the proper release of fertilizer. Over time, evaporation or infiltration of water from the soil further shrinks the compacted soil, exacerbating the blockage. On sloping mountainous or hilly terrain, traditional machinery tilts downward due to gravity, resulting in varying tillage depths. Rough terrain, characterized by gravel and gullies, also causes the equipment to vibrate violently during operation. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent crawler self-propelled deep plowing, soil crushing, stone removal and fertilization integrated machine, which forms a dynamic interception net through a number of reciprocating fertilizer pipes. The reciprocatingly vibrating fertilizer pipes break the soil adhering to the surface of the stone, and then the stone is hooked out by the reciprocating rake tooth assembly, which also combs the soil, increases the soil porosity, effectively maintains the soil pore network, promotes air and water penetration, and creates a suitable physical environment for soil maturation, which not only ensures the looseness of the cultivated layer, but also reduces the impact of stones on subsequent operations. The present invention fills the technical gap in efficient stone removal, improves the problem of excessive disturbance of soil structure by traditional stone removal mechanisms, and realizes the integrated and efficient operation of deep plowing, soil crushing, stone removal and fertilization through collaborative innovation of multiple mechanisms, significantly shortens the soil maturation cycle, and has the dual advantages of efficient stone removal and soil ecological protection.

[0006] This purpose is achieved by adopting the following technical solutions:

[0007] An intelligent crawler self-propelled deep tillage soil crushing and stone removal and fertilization integrated machine includes a stone removal and fertilization mechanism, the stone removal and fertilization mechanism includes a primary reciprocating mechanism, a secondary reciprocating mechanism, a support plate, a fertilizer pipe assembly and a rake tooth assembly, the support plate is sequentially provided with a rake tooth assembly and a fertilizer pipe assembly along the moving direction of the stone removal and fertilization mechanism, the rake tooth assembly includes a plurality of rake teeth, the plurality of rake teeth are arranged in parallel, the plane where the plurality of rake teeth are located is parallel to the moving direction of the stone removal and fertilization mechanism, the plane where the plurality of rake teeth are located is perpendicular to the soil plane, the primary reciprocating mechanism is used to make the plurality of rake teeth move in a direction perpendicular to the stone removal and fertilization mechanism The rake teeth are in a comb-like structure and can effectively hook stones. When the rake teeth swing, the stones intercepted by the fertilizer pipe assembly are directionally pushed to the side of the equipment to achieve efficient removal. The fertilizer pipe assembly includes a plurality of fertilizer pipes, which are arranged in parallel. The plane where the fertilizer pipes are located is perpendicular to the moving direction of the stone removal and fertilization mechanism. The two constitute a three-dimensional interception system, covering all possible stone movement paths. The plane where the fertilizer pipes are located is perpendicular to the plane where the rake teeth are located. The secondary reciprocating mechanism is used to make the fertilizer pipes reciprocate in a direction perpendicular to the moving direction of the stone removal and fertilization mechanism.

[0008] Several fertilizer pipes form a "flexible screen" with dynamic gaps through reciprocating movement to intercept stones. The vibration of the fertilizer pipes breaks the soil adhering to the surface of the stones, separating the stones from the soil. At the same time, the reciprocating movement of the fertilizer pipes also promotes increased fertilization uniformity, forming a horizontally uniform fertilization belt in the field. At the same time, the tapered spiral design of the spiral conveyor of the fertilizer pipes also effectively prevents the soil and fertilizer from blocking the fertilizer pipes. The fertilizer pipes intercept stones while fertilizing, and the rake teeth comb the soil while hooking stones, realizing multiple uses of one device. In addition, when the equipment moves forward, the reciprocating motion of the fertilizer pipes and the rake teeth synchronously disturbs the soil, further loosening the soil after deep plowing by the vertical rotary tillage blade group, improving the soil permeability and water and fertilizer retention capacity, accelerating the decomposition of organic matter and mineral weathering, shortening the maturation cycle, achieving efficient stone removal, and improving the problem of excessive disturbance of soil structure by traditional stone removal mechanisms affecting soil maturation.

[0009] Compared with existing devices, this device is different from existing soil stone removal mechanisms, which often remove stones through screens and need to go through three stages of excavation-screening-backfilling. The process is time-consuming and has high energy consumption and maintenance costs. Traditional devices perform deep plowing and stone removal in stages. When operating in sections, the interval between deep plowing and stone removal is usually ≥1 day. During this period, stones are embedded in the soil again due to soil settlement, water infiltration and other factors, and deep plowing causes uneven soil pore distribution, forming "micro-water accumulation areas" around the stones, accelerating the cementation of clay and stones. At the same time, during the excavation and stone removal process, the tillage layer structure is systematically destroyed, which reduces the soil aggregate retention rate, porosity, and soil biomass such as earthworms, directly inhibiting the decomposition process of organic matter, resulting in loss of mature soil and aggravating the difficulty of soil maturation.

[0010] The present invention adopts a reciprocating fertilizer pipe assembly to form a dynamic screen, so that when the equipment moves forward, stones in the soil after deep plowing are intercepted by the fertilizer pipe assembly, and at the same time, the vibrating fertilizer assembly breaks the soil adhered to the surface of the stones. The rake tooth assembly moves back and forth in front of the dynamic screen formed by the fertilizer pipe assembly, so that the stones intercepted in front of the fertilizer pipe assembly are directionally pushed to the side of the equipment, and efficient stone removal is achieved while deep plowing and fertilizing. In addition, the fertilizer pipe assembly and the rake tooth assembly also comb the soil while cleaning the stones, breaking up clay blocks in a flexible manner, maintaining the continuity of the pore network, and providing a habitat for microorganisms. The floating connection mechanism ensures the stability of the tillage mechanism. The tillage depth of the equipment is stable in sloping terrain, realizing the integrated and efficient operation of deep plowing, soil crushing, stone removal and fertilization, effectively improving the problem of excessive disturbance of the soil structure by traditional stone removal mechanisms, and effectively shortening the soil maturation cycle.

[0011] Furthermore, the several fertilizer pipes are arranged at equal intervals, and the minimum adjacent spacing between the several fertilizer pipes is between 8 and 12 cm. The 3-5 cm stones in the farmland account for about 60%-70%. Combined with the dynamic effect of the reciprocating motion of the fertilizer pipes, the distance of 8-12 cm between the fertilizer pipes and the reciprocating spacing of the fertilizer pipes are between 3 and 5 cm, which are suitable for the 3-5 cm stones in the farmland and are easy to remove. The reciprocating speed of the fertilizer pipes is between 0.3 and 0.6 m / s. When the speed is too high, the soil disturbance index increases and the aggregate destruction rate increases; when the speed is too low, the interception probability decreases, but the energy consumption is reduced. The moderate spacing enables the dynamic interception of the fertilizer pipes to intercept stones more efficiently without destroying soil aggregates.

[0012] Furthermore, the reciprocating spacing of the rake teeth is greater than the maximum distance between the fertilizer pipes, and the rake teeth swing beyond the range of the fertilizer pipes, thereby avoiding stone residue caused by edge blind spots in traditional equipment.

[0013] Furthermore, the plurality of rake teeth are arranged at equal intervals, and the minimum adjacent interval between the plurality of rake teeth is between 5 and 10 cm. When the equipment is moving, the rake teeth and the stones move relative to each other. When the interval is greater than the diameter of the stone, the stone can still be effectively hooked out by "collision offset". When the interval is between 5 and 10 cm, the disturbance radius of the rake teeth on the soil is 10-15 cm, which can flexibly break 2-5 cm soil blocks and retain most of the soil aggregates to avoid excessive disturbance. The reciprocating movement speed of the rake teeth is consistent with the movement speed of the stone removal and fertilization mechanism. The speed ratio is between 0.8 and 1 to ensure the interception probability. The ratio of 0.8-1 makes the rake teeth's motion trajectory present the characteristics of "pushing forward obliquely" during the forward movement of the equipment. This trajectory allows the rake teeth to form a continuous "interception-pushing" action on the stones during the forward movement of the equipment, avoiding the bouncing or missing of stones due to excessive vertical force. At the same time, it also avoids the low pushing efficiency when the ratio is too low, resulting in stone accumulation and omission, so that the power demand of the rake tooth drive system is reasonably matched with the equipment's travel power, ensuring the stone removal efficiency.

[0014] Furthermore, the fertilizer pipe assembly is provided with a fertilizer hopper, which is connected to a first-level reciprocating mechanism. The first-level reciprocating mechanism causes the fertilizer hopper to vibrate back and forth on the support plate. The vibration destroys the graded stacking of fertilizer particles, thereby improving the mixing uniformity of fertilizers of different particle sizes and reducing the agglomeration rate of fertilizers. The vibration of the fertilizer hopper is transmitted to the inlet of the fertilizer pipe to avoid blockage caused by static pressure accumulation.

[0015] Furthermore, the fertilizer pipe is provided with a spiral conveying member, which includes a spiral shaft, a first spiral blade and a second spiral blade. The first spiral blade and the second spiral blade are arranged on the spiral shaft. The first spiral blade is arranged in the fertilizer pipe. Fertilizer is first transmitted downward from the fertilizer hopper through the rotation of the first spiral blade. The second spiral blade is arranged outside the fertilizer pipe. The spiral shaft can rotate around its own axis. The first spiral blade and the second spiral blade are connected. The first spiral blade is a spiral blade with a constant diameter, and the second spiral blade is a conical spiral blade. The outer diameter of the second spiral blade decreases linearly from the fertilizer pipe outlet to one end of the spiral shaft, and the outer diameter of the blade at the outlet end decreases toward the shaft end, forming a conical guide surface with a larger front and a smaller back. The headway resistance when inserted into the soil is reduced. The fertilizer pipe moves in the soil to fertilize, and the soil is easily blocked at the fertilizer pipe outlet. The second spiral blade has an anti-blocking effect when rotating. When the second spiral blade rotates, the soil near the fertilizer pipe outlet can be pushed away to prevent soil accumulation from blocking the pipe outlet. During the rotation process, the second spiral blade can break up and stir the soil around the fertilizer pipe, especially for relatively compact soil, making it loose, which is beneficial to the growth of crop roots and also helps the fertilizer to mix better with the soil. The soil penetration resistance of the conical section is stable, which facilitates the precise control of the depth.

[0016] Furthermore, the distance between the first spiral blade and the wall of the fertilizer pipe is between 2 and 5 mm, and shear force is generated during rotation, which can scrape off clay or deliquescent fertilizer adhering to the pipe wall, thereby avoiding clogging of the fertilizer pipe.

[0017] Furthermore, the maximum outer diameter of the second spiral blade is identical to that of the first spiral blade, facilitating connection. The sudden change in cross-sectional area during the diameter change allows fertilizer to accumulate at the constriction, while also uniformizing stress distribution and improving mechanical life. The axial height of the second spiral blade is between 5 and 10 cm. This axial height allows the fertilizer to form a precise, moderately thick fertilizer belt in the soil. Too high a belt thickness results in nutrient waste and reduced efficiency, while too low a belt thickness results in a prolonged maturation period.

[0018] Furthermore, it also includes a floating connection mechanism, one end of the floating connection mechanism is provided with a power moving mechanism, and the other end of the floating connection device is provided with a vertical deep plowing rotary blade group and a stone removal and fertilization mechanism. The floating connection mechanism includes a power base plate, a connecting rod, a hydraulic cylinder and a deep plowing device seat. The power base plate is connected to the power moving structure, and the deep plowing device seat is connected to the vertical rotary blade group. There are four connecting rods, and the two ends of the four connecting rods are respectively hinged to the deep plowing device seat and the power chassis seat. The four-link rod has the characteristics of equal length of opposite sides and parallel movement, so that the deep plowing device seat and the power base plate always maintain a horizontal posture. One end of the hydraulic cylinder is hinged to the connecting rod, and the hydraulic cylinder drives the connecting rod to move when it is extended and retracted. When the ground slope changes, the hydraulic cylinder extends and retracts to drive the four-link rod to rotate through the hinge point to keep the plowing depth consistent. When the equipment is traveling on rugged terrain with gravel, gullies, etc., it will produce severe vibrations. The hydraulic cylinder provides dynamic buffering for the entire floating connection device by adjusting the extension and retraction amount in real time. When the slope changes, the four-link rod can rotate through the hinge point to adapt to the terrain. The hydraulic cylinder adjusts the posture of the four-link rod by active extension and retraction to compensate for the height difference, so that the depth of the tillage mechanism into the soil is consistent, ensuring the stability of the tillage mechanism.

[0019] Compared with the prior art, the Salvia miltiorrhiza harvesting and collecting device for heavy clay soil provided by the present invention has the following beneficial effects:

[0020] 1. The intelligent crawler self-propelled deep plowing, soil crushing, stone removal and fertilization integrated machine of the present invention forms a dynamic interception net through a reciprocating fertilizer pipe assembly. Stones in the soil are intercepted by the fertilizer pipe assembly, and the rake tooth assembly reciprocates in front of the dynamic screen formed by the fertilizer pipe assembly, so that the stones intercepted in front of the fertilizer pipe assembly are directionally pushed to the side of the equipment. While deep plowing and fertilizing, efficient stone removal is achieved, and the soil is also combed, effectively maintaining the soil pore network and effectively shortening the soil maturation cycle, realizing the integrated and efficient operation of deep plowing, soil crushing, stone removal and fertilization, and avoiding the problem of excessive disturbance of the soil structure by traditional stone removal mechanisms affecting soil maturation.

[0021] 2. The intelligent crawler self-propelled deep tillage, soil crushing, stone removal and fertilization integrated machine of the present invention generates an outward radial component force when the conical spiral at the outlet of the spiral conveyor of the fertilizer pipe rotates, pushing the fertilizer to spread around so that it is more evenly distributed at the outlet of the fertilizer pipe, effectively avoiding the blockage of the fertilizer pipe by soil and fertilizer. As the conical spiral rotates, not only the soil is loosened, but the fertilizer is also evenly pushed into the loose soil, so that the fertilizer can be more widely and evenly dispersed in the soil.

[0022] 3. The present invention provides an intelligent crawler self-propelled deep tillage, soil crushing, stone removal and fertilization all-in-one machine, which connects a power movement mechanism and a vertical deep tillage rotary blade group through a floating connection mechanism. The four-link of the floating connection mechanism has the characteristics of equal length and parallel movement of opposite sides, and the extension and retraction amount is adjusted in real time by the hydraulic cylinder, providing dynamic buffering for the entire floating connection device. When the slope changes, the four-link can rotate through the hinge point to adapt to the terrain. The hydraulic cylinder adjusts the posture of the four-link through active extension and retraction to compensate for the height difference, so that the tillage mechanism has a consistent depth in the soil, thereby ensuring the stability of the tillage mechanism.

DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0034] Example 1

[0035] like Figure 1 and Figure 2 The shown intelligent crawler self-propelled deep plowing, soil crushing, stone removal and fertilization integrated machine includes a stone removal and fertilization mechanism, which includes a first-level reciprocating mechanism, a second-level reciprocating mechanism, a support plate 4, a fertilizer pipe assembly and a rake tooth assembly. The support plate 4 is provided with a rake tooth assembly and a fertilizer pipe assembly in sequence along the moving direction of the stone removal and fertilization mechanism. The rake tooth assembly includes a plurality of rake teeth 1, which are arranged in parallel. The plane where the plurality of rake teeth 1 are located is parallel to the moving direction of the stone removal and fertilization mechanism, and the plane where the plurality of rake teeth 1 are located is perpendicular to the soil plane. Before the equipment is put into use, trenches are dug in the soil to be matured, with a depth of 30 cm and a spacing of 1 m between adjacent trenches.

[0036] After the trenching operation, the equipment enters the working area between adjacent trenches to work. The vertical deep tillage rotary blade group 22 is arranged in front of the stone removal and fertilization mechanism. When the equipment is working, the vertical deep tillage rotary blade group 22 first deeply plows the soil, and the stone removal and fertilization mechanism removes stones and fertilizes the soil after deep plowing. When the equipment is started, the plane where the rake teeth 1 are located is located at the center line of the equipment. At the moment the equipment is started, the stones will generate impact force on the rake teeth. The plane where the rake teeth 1 are located is located at the center line of the equipment. The impact force will be relatively evenly distributed on both sides of the equipment, and will not cause obvious eccentric load on the equipment. The reciprocating movement of the first-level reciprocating mechanism drives a number of rake teeth 1 to reciprocate along the moving direction perpendicular to the stone removal and fertilization mechanism. The rake teeth 1 have a comb-like structure, which can effectively hook stones. When the rake teeth 1 swing, the stones intercepted by the fertilizer pipe assembly are pushed directionally. Move it to the ditch on the side of the equipment to achieve efficient cleaning. The fertilizer pipe assembly includes a number of fertilizer pipes 2, which are arranged in parallel. The planes of the fertilizer pipes 2 are perpendicular to the moving direction of the stone removal and fertilization mechanism, and the planes of the fertilizer pipes 2 are perpendicular to the planes of the rake teeth 1. The secondary reciprocating mechanism drives the fertilizer pipes 2 to reciprocate in a direction perpendicular to the moving direction of the stone removal and fertilization mechanism. The fertilizer pipes 2 form a flexible screen with dynamic gaps through reciprocating movement to intercept stones. The vibration of the fertilizer pipes 2 breaks the soil adhered to the surface of the stone, separating the stone from the soil. At the same time, the reciprocating movement of the fertilizer pipes 2 also promotes increased uniformity of fertilization. The fertilizer pipes 2 complete stone interception while fertilizing. The stones intercepted by the fertilizer pipes 2 are hooked out by the rake teeth 1 while combing the soil, achieving multiple effects.

[0037] In some embodiments, the primary reciprocating mechanism and the secondary reciprocating mechanism may be in various forms, such as a rack and pinion structure, a cam mechanism, and a pneumatic / hydraulic reciprocating mechanism. The present invention preferably uses two reciprocating mechanisms, such as Figure 4As shown, the first-stage reciprocating mechanism includes a screw 15, a transmission pair 16, a guide rod 17, a spring assembly 18, a bevel gear set 19 and a limit spring member 20. The screw 15 and the guide rod 17 are arranged in parallel on the support plate 4. The transmission pair 16 is connected to the rake tooth assembly. The transmission pair 16 is threadedly sleeved on the screw 15. The transmission pair 16 is sleeved on the guide rod 17. The screw 15 can rotate around its own axis. When the screw 15 rotates around its own axis, the transmission pair 16 moves with the rotation of the screw 17. The spring assembly 18 is provided at both ends of the guide rod 17. As the transmission pair 16 moves, the transmission pair 16 and the spring assembly 18 are released, and the elastic force of the spring assembly 18 will continue to increase, exceeding the combined force of the screw driving force and other resistances. The screw 15 A bevel gear set 19 is provided at one end, and a limit spring part 20 is provided at the other end of the screw 15, causing the screw 15 to move relative to the limit spring part 20, and the screw 15 is engaged with the bevel gear in the other rotation direction, and the transmission pair 16 starts to move in the opposite direction, thereby driving the rake tooth assembly to move back and forth. The secondary reciprocating mechanism includes an active part 12, a slider 13 and a fixed block 14. The slider 13 is sleeved on the active part 12, and the slider 13 is sleeved on the fixed block 14. When the active part 12 rotates around the axis, it drives the slider 13 to move back and forth, thereby driving the fertilizer pipe 2 and the fertilizer bucket 3 to move back and forth. The deep plowing depth of the vertical deep plowing rotary blade group 22 is 25-30 cm, and the rake tooth assembly and the fertilizer pipe assembly are the same as the depth of penetration into the soil of the vertical deep plowing rotary blade group 22.

[0038] In some embodiments, Figure 3 and Figure 4 As shown, the fertilizer pipes 2 are arranged at equal intervals, the minimum adjacent spacing between the fertilizer pipes 2 is between 8 and 12 cm, the reciprocating speed of the fertilizer pipes 2 is between 0.3 and 0.6 m / s, the reciprocating spacing of the fertilizer pipes 2 is between 3 and 5 cm, the reciprocating spacing of the rake teeth 1 is greater than the farthest distance between the fertilizer pipes 2, and the reciprocating spacing of the rake teeth 1 is equal to the spacing between adjacent grooves, which facilitates the removal of stones.

[0039] In some embodiments, Figure 1 and Figure 2As shown, the several rake teeth 1 are arranged at equal intervals, and the minimum adjacent spacing between the several rake teeth 1 is between 5 and 10 cm. The moving speed of the stone removal and fertilization mechanism is 0.2 m / s, and the ratio of the reciprocating speed of the rake teeth 1 to the moving speed of the stone removal and fertilization mechanism is between 0.8 and 1. The reciprocating speed of the rake teeth 1 is 0.2 m / s. The maximum distance between the rake teeth 1 is 1.3 m, and the maximum distance between the rake teeth 1 is 1.2 to 1.5 times the spacing between adjacent furrows, that is, the working width. This ratio not only avoids the farthest distance between the rake teeth 1 being too small to cause stones to be missed, but also prevents the farthest distance between the rake teeth 1 from being too large to cause energy waste. When the rake teeth 1 are arranged at this spacing, the overlap of the track coverage areas of adjacent rake teeth 1 in the soil ensures that stones will be intercepted by the rake teeth 1 no matter where they are in the working width. At the same time, the oblique thrust of the overlapping area can push the stones to the center, reduce the accumulation of stones at the fertilizer pipe 2, and maximize the coverage area and stone removal efficiency.

[0040] In some embodiments, Figure 5 As shown, the fertilizer pipe assembly is provided with a fertilizer hopper 3, which is connected to a primary reciprocating mechanism, driving the fertilizer hopper 3 and the fertilizer pipe 2 to move back and forth on the support plate 4, thereby reducing the agglomeration rate of the fertilizer. The vibration of the fertilizer hopper is transmitted to the fertilizer pipe inlet, avoiding blockage caused by static pressure accumulation.

[0041] Example 2

[0042] Based on the first embodiment, Figure 6 As shown, the fertilizer pipe 2 is provided with a spiral conveyor, which includes a spiral shaft 5, a first spiral blade 6 and a second spiral blade 7. The first spiral blade 6 and the second spiral blade 7 are arranged on the spiral shaft 5, the first spiral blade 6 is arranged inside the fertilizer pipe 2, and the second spiral blade 7 is arranged outside the fertilizer pipe 2. The spiral shaft 5 can rotate around its own axis, and the rotation of the spiral shaft drives the spiral blades to rotate, so that the fertilizer is output from the fertilizer pipe outlet as the spiral rotates. The first spiral blade 6 and the second spiral blade 7 are connected, the first spiral blade 6 is a spiral blade of equal diameter, and the second spiral blade 7 is a conical spiral blade. The outer diameter of the second spiral blade 7 decreases linearly from the outlet of the fertilizer pipe 2 to one end of the spiral shaft 5.

[0043] In some embodiments, the distance between the first spiral blade 6 and the wall of the fertilizer pipe 2 is between 2 and 5 mm, the diameter of the fertilizer pipe is 5 cm, the rotation speed of the spiral conveyor in the fertilizer pipe is 100 r / min, the maximum blade outer diameter of the second spiral blade 7 is the same as the outer diameter of the first spiral blade 6, and the axial height of the second spiral blade 7 is between 5 and 10 cm.

The floating connection mechanism includes a power base plate 8, a connecting rod 9, a hydraulic cylinder 10 and a deep tillage device seat 11. The power base plate 8 is connected to the power moving structure 21, and the deep tillage device seat 11 is connected to the vertical rotary blade group. There are four connecting rods 9, and the four connecting rods 9 are respectively hinged at both ends of the deep tillage device seat 11 and the power moving structure 21. The power chassis seat 8, through the characteristics of equal length of opposite sides and parallel movement, makes the plane where the deep plowing device seat 11 is located and the plane where the power base plate 8 is located always in a parallel state. One end of the hydraulic cylinder 10 is hinged to the connecting rod 9, and the hydraulic cylinder 10 can be extended and retracted. The hydraulic cylinder 10 is used to drive the connecting rod 9 to move. When the ground slope changes, the hydraulic cylinder is extended and retracted to drive the four-link to rotate through the hinge point. The extension and retraction amount is adjusted in real time by the hydraulic cylinder, providing dynamic buffering for the entire floating connection device, ensuring the stability of the tillage mechanism.
