Description

Technical Field

[0001] The invention relates to the technical field of rotary tillage, fertilization and sowing, in particular to a rotary tillage, fertilization and sowing machine based on strip covering. Background Art

[0002] Strip mulching is a key technology in conservation tillage. Its core concept is to cultivate, fertilize, and sow only the "strips" (the areas within the rows) where crops are grown, while the areas between rows maintain their original soil structure or are covered with materials such as straw and stubble, minimizing soil disturbance and exposure, thereby achieving the dual goals of efficient resource utilization and ecological protection.

[0003] In the rice-wheat, rice-corn and other rotation modes, the amount of straw of the previous crop is large and the stubble is high, which leads to the problems of straw clogging, difficulty in entering the soil for the furrow opener and empty seed bed in the traditional rotary tillage seeder during operation. Although the existing technology attempts to reduce soil disturbance through strip tillage, it still has the following shortcomings. For example, the invention patent with publication number CN117898046A "A strip stubble shredding rotary tillage and fertilization seeder" adopts a composite process of strip stubble shredding-strip rotary tillage and fertilization-ditching and sowing to design a strip stubble shredding rotary tillage and fertilization seeder, which can achieve targeted chopping and rotary tillage of straw, achieve the purpose of preventing machine congestion and entanglement, and effectively solve the problems of difficulty in furrowing and empty seed bed. However, the overall seed and fertilizer stratification is insufficient, and the fertilizer discharge depth cannot be adjusted, which easily leads to the problem of seedling burn in subsequent sowing;

[0004] To this end, we propose a rotary tillage fertilization seeder based on strip mulching. Summary of the Invention

The holes on the outer wall of the seeding barrel are arranged corresponding to the protrusions on the convex column sleeve. The inner wall of the seeding barrel is fixedly connected to the seed box with an arc baffle, and the outer wall of the seeding barrel is slidably connected to an isolation sleeve.

[0009] Furthermore, a power transmission mechanism is installed on the main beam, and the power transmission mechanism includes a universal joint drive shaft, a gearbox and a guide plate group. The gearbox is installed on the top of the cover shell, and the universal joint drive shaft is connected to the gearbox side.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-9 , the present invention provides a technical solution:

[0030] Example 1: In strip mulching rotary tillage fertilization and sowing technology, precise control of fertilization and sowing position is the core technical difficulty to avoid conflicts between seeds and fertilizers. Usually, seeds and fertilizers are arranged in a vertical layered structure, with fertilizer at the bottom and seeds at the top, taking advantage of the natural isolation of the soil. The fertilizer is located 3-7 cm below the seeds. The fertilizer is slowly released as water seeps down and is gradually absorbed by the roots as they grow downward, avoiding burning of the seedlings.

[0031] For this reason Figure 1 、 Figure 2 and Figure 3As shown, the strip-covered rotary tillage fertilizer seeder is driven by a tractor, with a suspension frame 2 installed on the side of the main beam 1, and a rotary tillage cutter disc 5 for cutting and throwing the soil installed at the front end of the main beam 1. A cover 4 is provided at the rear, and a floating fertilizer discharge mechanism 6 installed in the cover 4 discharges fertilizer into the bottom of the crushed soil in a quantitative and deep manner. Subsequently, a sowing mechanism 14 installed on the suspension frame 2 is used for secondary soil breaking and shallow sowing. Finally, the soil is compacted by a pressing roller 20, so that the entire seed fertilizer is applied vertically and quickly.

[0032] In order to drive the main beam 1, a power transmission mechanism 3 is provided at its front end. Figure 5 As shown, the universal joint transmission shaft 301 is connected to the tractor power output shaft, and when it rotates, the gears inside the gearbox 302 and the drive shaft group 304 rotate, as shown in FIG. Figure 1 As shown, the drive shaft group 304 is divided into two, upper and lower, which rotate in conjunction with the gears installed on the side wall of the cover 4, and the surface of the drive shaft group 304 at the bottom of the cover 4 is correspondingly sleeved with the rotary tillage disc 5, as shown in FIG. Figure 3 As shown, the rotation of the universal joint drive shaft 301 ultimately drives the entire rotary tillage cutter disc 5 to rotate, completing the front-end cutting and throwing operations of the soil, providing a foundation for subsequent rapid trenching and covering of the soil;

[0033] The power transmission mechanism 3 also includes a guide plate group 303, which is connected to the fertilizer storage box 7 on the main beam 1. The guide plate group 303 is driven by the gearbox 302 and the central axis of the belt-connected guide plate group 303 rotates synchronously. Figure 5 As shown, the central axis of the guide disc group 303 is connected to the rotating shaft 2 9 in the fertilizer storage box 7 through gear meshing, driving the discharge fan 10 in the isolation chamber 8 in the fertilizer storage box 7 to rotate. According to the strip planting area, the soil is broken by the rotary cutter head 5 as the planting object, which is usually 30-50 cm wide. The isolation chamber 8 in the entire fertilizer box is opened to correspond to the planting area, and it is convenient for the subsequent automatic discharge of fertilizer. The floating fertilizer discharge mechanism 6 is installed on the inner side of the cover shell 4;

[0034] like Figure 6 As shown, the fertilizer in the fertilizer storage box 7 falls into the fertilizer discharge cover 605 through the guide pipe 606, and the entire fertilizer discharge cover 605 is slidably connected to the inner wall of the cover shell 4, and intermittent ground chiseling is adopted to discharge the fertilizer. The front end of the fertilizer discharge cover 605 is bent, and the discharge port is inclined downward, not perpendicular to the ground, which avoids the outlet being blocked due to long-term contact with the soil, and at the same time avoids the problem of fertilizer discharge waste when the fertilizer discharge cover 605 moves upward. The guide pipe 606 arranged on the side of the fertilizer discharge cover 605 is buckled and locked. As the fertilizer discharge cover 605 rises, the guide pipe 606 is automatically squeezed and closed, thereby realizing the automatic operation of pressing the fertilizer discharge cover 605 to discharge the material and moving it upward to lock the material;

[0035] As the planting depth of different seeds is different, the fertilizer discharge depth of the entire fertilizer discharge cover 605 also needs to be controlled. For this purpose, a sliding axis clamp 604 is installed on the inner side of the entire cover shell 4, and a swing rod 603 is installed on the axis clamp 604. One end of the swing rod 603 is movably connected to the fertilizer discharge cover 605 through a connecting rod. The axis is tilted by the swing rod 603 with the axis clamp 604 to swing, thereby driving the entire fertilizer discharge cover 605 to move up and down. As for the drive of the swing rod 603, a rotating shaft 601 is movably connected to the inner side of the cover shell 4, and a turntable 602 is evenly fixed on the rotating shaft 601. Figure 6 As shown, a groove is provided on the turntable 602, and the protrusion at the end of the rocker arm 603 abuts against the groove on the turntable 602. As the turntable 602 rotates, the entire rocker arm 603 is driven to rotate up and down. As for the control of the up and down range of the fertilizer discharge cover 605 at the end of the rocker arm 603, the axis clamping block 604 is adjusted at the bottom position of the cover shell 4, and the side screw rod of the axis clamping block 604 is rotated to realize its sliding on the rocker arm 603. The more it moves to the right, the smaller the range of movement of the entire fertilizer discharge cover 605, and the more it moves to the left, the larger the range of movement of the rocker arm 603. By adjusting the position of the axis clamping block 604 at the bottom position of the cover shell 4, the subsequent soil fertilizer discharge depth can be automatically adjusted, thereby adapting to fertilizing crops at different depths. At the same time, regarding the adjustment of the fertilization frequency, as shown in FIG. Figure 4 As shown, the end of the second shaft 9 in the fertilizer storage box 7 is connected to the end of the first shaft 601 through a belt pulley and a belt. The speed of the first shaft 601 is adjusted by changing the size of the transmission belt pulley, and the fertilizer discharge frequency is finally adjusted.

[0036] Example 2: Install the sowing mechanism 14 on the side of the suspension frame 2, as shown in FIG. Figure 7 As shown, a contour transmission assembly 12 is used to automatically adjust the height of the knife roller according to the undulations of the terrain to maintain a consistent tillage depth. An upper roller 11 is movably connected between the two. The roller 11 rotates to drive the rotation shaft 3 13 connected to the sprocket transmission housing of the entire contour transmission assembly 12. The gear chain on the elastic buffer frame then synchronously drives the internal boss sleeve 142 of the entire sowing mechanism 14 to rotate.

[0037] like Figure 8 As shown, the outer wall of the entire convex column sleeve 142 is evenly fixed with convex columns, and the cylindrical radius of the convex columns on the same section is the same, and a seed discharging cylinder 143 for seed conduction is also provided correspondingly. The convex columns on the convex column sleeve 142 and the seed storage holes on the seed discharging cylinder 143 are correspondingly arranged, which can drive the entire seed discharging cylinder 143 to rotate and apply a squeezing force on the seeds stuck in the holes, thereby preventing the holes on the seed discharging cylinder 143 from being blocked and affecting the subsequent continuous feeding of seeds;

[0038] The top of the entire seed box 141 is used for storing seeds, and to prevent small-particle seeds from falling directly from the holes on the seed cylinder 143, an arc-shaped baffle 144 is fixed on its inner wall to place the seeds in the seed box 141, and an isolation sleeve 145 is slidably connected to the outer wall of the seed cylinder 143. In combination with the change in the radius of the holes on the outer wall of the seed cylinder 143 for storing seeds, the uniformity of seed discharge is controlled. Initially, the entire isolation sleeve 145 completely covers the entire seed cylinder 143, resulting in the seeds discharged from the seed box 141 being unable to be discharged normally. As for the position control of the isolation sleeve 145 on the seed cylinder 143, Figure 8 Combine Figure 9 As shown, an adjusting rod 15 is installed on the side of the seed box 141, which is similar to a screw drive. When the end of the adjusting rod 15 is manually rotated, the tapered block 17 of the adjusting rod 15 located in the seed box 141 and movably connected thereto moves downward.

[0039] The lower part of the conical block 17 is connected to the rod 18, which is rotated. As the conical block 17 descends, the cross section squeezes the rod 18 and rotates. Figure 9 As shown, when the push rod 18 rotates clockwise, the other end of the push rod 18 contacts the other side of the isolation sleeve 145, causing the isolation sleeve 145 to slide on the seed cylinder 143 and squeeze the spring 19 installed on one side. The holes of the seed cylinder 143 on the corresponding cross-section covered by the isolation sleeve 145 are exposed in turn, causing the seeds in the seed box 141 to fall into the holes on the seed cylinder 143 and be discharged as the seed cylinder 143 rotates. By controlling the isolation sleeve 145 to slide on the seed cylinder 143, the corresponding holes are opened for seed storage and feeding, which facilitates the subsequent feeding of seeds of different particle sizes and improves the uniformity of seed discharge.

[0040] As the seeds fall from the bottom of the seed box 141, the knife seat 16 installed at the front end of the seed box 141 creates a crack in the soil, and the seeds fall into the cracked soil. At the same time, the scraper installed at the rear end of the seed box 141 completes the covering of the turned soil, and finally the soil is rolled by the pressing roller 20 behind the suspension frame 2 to complete the soil compaction process;

[0041] The double furrow opener design independently controls the seed furrow and fertilizer furrow to ensure precise spacing. At the same time, it compacts the soil after sowing to prevent fertilizer from floating up. At the same time, it controls the depth of intermittent fertilization and matches it with the sowing depth to ensure the vertical distribution of seeds and fertilizers, which is conducive to the slow release of fertilizers as water infiltration and gradual absorption by the roots as they grow downward, avoiding seedling burn and achieving the goal of "seeds in the safe zone and fertilizers in the high-efficiency zone", laying the foundation for the large-scale promotion of strip mulching technology.
