[0002] Conservation tillage is a new agricultural farming concept that emphasizes agricultural production under the premise of minimizing disturbance to the soil structure. Conservation tillage mainly includes no-tillage, reduced tillage and cover tillage. Its core advantage is that it can maintain the natural structure of the soil, increase the organic matter content in the soil, and reduce soil erosion.

DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] For example, see Figures 1 to 9 In an embodiment of the present invention, a soil deep loosening device for conservation tillage includes a fixed mounting column 5, one end of the fixed mounting column 5 is provided with a driving telescopic column 4, the outer end of the driving telescopic column 4 is provided with a transmission mounting plate 1, one end of the transmission mounting plate 1 is provided with a telescopic driving member 3 in cooperation with the driving telescopic column 4, the other end of the transmission mounting plate 1 is provided with a double-layer traction ring 2, and further includes:

[0035] The depth adjustment stabilization mechanism comprises an arc-shaped dividing column 7 and a stabilization structure. The other end of the fixed installation column 5 is connected to one end of the arc-shaped dividing column 7. The other end of the arc-shaped dividing column 7 is provided with an arc-shaped breaking head 25.

[0036] A towing type soil loosening mechanism, the towing type soil loosening mechanism comprising a towing guide installation structure, a towing combination installation structure and a soil loosening structure;

[0037] The cross sections of the fixed installation column 5 and the driving telescopic column 4 are both shuttle-shaped.

[0038] The double-layer traction ring 2 is connected to an external traction device. Under the traction of the external traction device, the movement of the device is realized. Under the action of the arc-surface breaking head 25, it is similar to a plow that easily sinks into the soil under its own weight, and under the action of the upper arc surface of the arc-surface breaking head 25, it continues to move downward, so that the arc-shaped dividing column 7 is inserted into the ground and moves downward, and is immersed in the soil together with the fixed installation column 5. In this process, the stable structure first realizes strip-shaped breaking, which is convenient for the towed loosening mechanism to be inserted into the ground, and then forms a force balance with the height of the external traction device, maintains movement at a certain depth, and cooperates with the towed loosening mechanism to realize deep loosening of the soil;

[0039] The length of the telescopic driving member 3 is adjusted to drive the telescopic column 4 to meet the needs of deep tillage operations at different depths and to increase the depth range of the deep tillage operations.

[0040] Example 2, based on Example 1, please refer to Figure 1-2 In the embodiment of the present invention, the upper half of the arc-shaped dividing column 7 at one end of the arc-shaped breaking head 25 is embedded with an inclination driving member 24, and rotating breaking pieces 8 are symmetrically arranged on both sides of the arc-shaped dividing column 7. The rotating breaking pieces 8 are rotatably connected to the inclination driving member 24 through a rotating shaft, and the inclination driving member 24 is connected to the external power supply element through an internal telescopic wiring 20;

[0041] The stabilizing structure includes a balancing guide rod 26 symmetrically arranged on the arc-shaped dividing column 7 , a plurality of stabilizing guide columns 27 arranged at equal intervals on the balancing guide rod 26 , and conical guide heads 28 symmetrically arranged at both ends of the stabilizing guide column 27 .

[0042] The arc surface breaking head 25 moves with the traction of the traction device. Based on its fixed arc surface, it can cooperate with the stable structure to maintain movement at a certain depth. The inclination angle of the rotating breaking piece 8 is adjusted by the driving of the inclination driving member 24, thereby breaking the balance achieved by the arc surface breaking head 25 and the stable structure, so that it can break the ground at different depths.

[0043] The inclination drive member 24 may be a BZFM type motor;

[0044] The balancing guide rod 26 moves with the fixed mounting column 5 and cooperates with the telescopic adjustment of the driving telescopic column 4 to ensure that the balancing guide rod 26 is always in a horizontal state. At this time, the stabilizing guide column 27 and the conical guide head 28 thereon can well ensure stable guiding movement within a certain depth, balance the torsion and deviation caused by loosening the soil by the towing type loosening mechanism, and ensure efficient and high-quality completion of the deep loosening operation.

[0045] Example 3, based on Example 1, please refer to Figure 3 to Figure 7 In the embodiment of the present invention, the towing guide installation structure includes a U-shaped installation frame 6 arranged on the fixed installation column 5, the inner side of the U-shaped installation frame 6 is symmetrically provided with a guide installation groove 13, a trapezoidal installation plate 11 is provided to match the U-shaped installation frame 6, and guide fixing columns 15 are symmetrically provided on both sides of the trapezoidal installation plate 11 to match the guide installation groove 13, and a hard rubber layer is provided on the surface of the guide fixing column 15, and a plurality of extrusion fixing studs 10 are equidistantly provided on the outer side of the U-shaped installation frame 6 to match the guide installation groove 13, one end of the extrusion fixing stud 10 extends into the guide installation groove 13, and a turntable 14 is provided at the other end of the extrusion fixing stud 10;

[0046] The towing combined mounting structure includes a combined mounting plate 9 arranged on the side of the trapezoidal mounting plate 11 facing away from the fixed mounting column 5, a plurality of at least one limiting guide grooves 21 are evenly spaced on the side of the combined mounting plate 9 facing away from the fixed mounting column 5, a matching mounting hole 16 is arranged on the combined mounting plate 9 at one end of the limiting guide groove 21, a limiting mounting column 17 is arranged to match the limiting guide groove 21, a limiting mounting block 22 is arranged at one end of the limiting mounting column 17 extending into the limiting guide groove 21, a mounting groove 23 is arranged on the inner wall of the limiting guide groove 21 to match the limiting mounting block 22, and one side of the limiting mounting block 22 is roughened to match the mounting groove 23.

[0047] The guide installation of the trapezoidal installation plate 11 and the U-shaped installation frame 6 is achieved through the cooperation of the guide installation groove 13 and the guide fixing column 15, and then the turntable 14 is rotated to rotate the extrusion fixing stud 10 facing the guide fixing column 15 until the extrusion fixing stud 10 is squeezed and locked with the hard rubber layer on the guide fixing column 15, so as to achieve the fixed installation of the trapezoidal installation plate 11;

[0048] According to the needs of the loosening operation, select the required number of loosening structures for installation, put the limit installation column 17 and the limit mounting block 22 into the guide limit guide groove 21 in conjunction with the matching mounting hole 16, and move along the limit guide groove 21 to the other end away from the matching mounting hole 16. At this time, pull the limit installation column 17 outward so that the limit mounting block 22 is stuck in the mounting groove 23, and repeat the above steps to complete the installation of the required loosening structure;

[0049] As the external traction equipment moves, the limiting mounting block 22 and the mounting groove 23 are limited, and the loosening structure is pulled synchronously. The roughened limiting mounting block 22 cooperates with the mounting groove 23 to further improve the traction stability and avoid the generation of traction twisting.

[0050] Example 4, based on Example 1, please refer to Figure 8-Figure 9In the embodiment of the present invention, the loosening structure includes a curved surface mounting cover 12, the other end of the limit mounting column 17 is connected to the convex side of the curved surface mounting cover 12, and the limit mounting column 17 at the connection is symmetrically provided with a force reinforcement plate, and the force reinforcement plates are all connected to the curved surface mounting cover 12;

[0051] A traction mounting plate 19 is disposed opposite to the concave side of the arc surface mounting cover 12, and two groups of traction connecting rods 18 are symmetrically disposed between the traction mounting plate 19 and the arc surface mounting cover 12. A rotating mounting cylinder 32 and a traction mounting cylinder 33 are disposed at both ends of the traction connecting rod 18, respectively. The two groups of traction mounting cylinders 33 are rotatably mounted at both ends of the arc surface mounting cover 12 through a rotating shaft, and the two groups of rotating mounting cylinders 32 are rotatably mounted at both ends of the traction mounting plate 19 through a rotating shaft.

[0052] The convex side of the arc surface mounting cover 12 is evenly spaced with a plurality of primary loosening pieces 31, which are vertically arranged. The two ends of the traction mounting plate 19 are symmetrically provided with curved surface mounting frames 29, and the curved surface mounting frames 29 are evenly spaced with a plurality of secondary loosening pieces 30, and the primary loosening pieces 31 and the secondary loosening pieces 30 are vertically arranged in space.

[0053] The arc surface mounting cover 12 and the curved surface mounting frame 29 are made of elastic material.

[0054] As the traction movement proceeds, the towing loosening mechanism moves and tilts into the ground, and moves stably at a certain depth under the action of the depth adjustment stabilization mechanism. At this time, the convex side of the arc-surface mounting cover 12 contacts the soil, and the convex side pushes the soil open. At the same time, the first-level loosening piece 31 thereon moves accordingly to achieve the first-level segmentation of the soil. The traction mounting plate 19 moves synchronously under the action of the traction connecting rod 18. The curved mounting frame 29 and the second-level loosening piece 30 thereon move with the traction mounting plate 19 to perform the second-level segmentation of the soil after the first-level segmentation. Since the first-level loosening piece 31 and the second-level loosening piece 30 are vertically arranged in space, the bulkiness of the soil can be significantly improved, and the volume of deep loosening can be increased, and the quantity and quality can be improved simultaneously.

[0055] Since the secondary loosening pieces 30 are relatively dense, when the soil segmentation effect of the secondary loosening is poor, the stress on the secondary loosening pieces 30, the curved mounting frame 29 and the traction mounting plate 19 increases significantly, and the traction link 18 drags the curved mounting cover 12, causing the curved mounting cover 12 to deform under stress, and the degree of curvature of the convex side of the curved mounting cover 12 increases, so that the primary loosening pieces 31 thereon are unfolded, which can capture more soil and improve its ability to segment the soil, and avoid soil adhesion between the primary loosening pieces 31, resulting in uneven soil segmentation or even no segmentation, which directly acts on the secondary loosening pieces 30 at the rear, making the secondary loosening more difficult and reducing the quality of the loosening. When the soil between the primary loosening pieces 31 gradually decreases with the unfolding state and continuous movement, the curved mounting cover 12 slowly recovers its shape, and under this passive dynamic adjustment, the deep soil loosening operation is completed.

[0056] The force deformation of the arc-shaped mounting cover can cope with the impact of debris in the soil, including tree roots and stones, and can change the passing angle through deformation, push away the debris, avoid damage caused by direct contact between the first loosening piece 31 and the second loosening piece 30, and protect the equipment.
