Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and particularly relates to an active power grass root knot breaking and soil permeability compound operation machine. Background Art

[0002] As an important ecological barrier and natural resource treasure house in China, the grassland not only bears the key function of maintaining regional ecological balance, but also is the foundation of the production and living of the vast number of herdsmen. However, the grassland ecological system is inherently fragile. Under the influence of long-term intensive grazing, disorderly reclamation and other over-utilization behaviors, as well as the extensive management mode, a large number of grasslands have the phenomenon of disorderly knotting of grass roots, resulting in the destruction of the soil pore structure, a significant decline in air permeability and water permeability, and then triggering ecological problems such as grassland degradation and desertification, threatening the grassland ecological security and the sustainable development of herdsmen.

[0003] At present, the domestic research on the technology of cutting roots and loosening soil for degraded grasslands is relatively less, and most of the research is carried out with reference to traditional farmland soil loosening machinery. However, the unique root-soil complex structure of degraded grasslands significantly improves the shear strength of the soil and enhances its resistance to external force breaking. This makes the traditional grassland soil loosening machine face technical bottlenecks such as large root cutting resistance and difficult soil fragmentation during the operation process, and the effect of breaking dense grass root knots and improving soil permeability is not good, which is difficult to meet the actual needs of degraded grassland ecological restoration. Therefore, there is an urgent need to develop an active power grass root knot breaking and soil permeability compound operation machine to solve the problem of degraded grassland ecological governance.

[0045] The spring provides an adaptive adjustment function for the broken root knotting monomer by applying a stable pressing force.

[0053] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0054] (1) Innovatively adopt the linkage operation mode of the soil permeability device and the root knot-breaking device. During the mechanical advancement, the root knot-breaking device cooperates with the root knot-breaking vibration device of the soil permeability device to achieve the organic combination of horizontal displacement and high-frequency reciprocating motion in the vertical direction. This design not only significantly increases the operation coverage area of the root knot-breaking device, effectively improves the soil permeability of saline-alkali grasslands, but also greatly reduces the tillage resistance through the dynamic operation method, significantly enhancing the operation efficiency and energy utilization efficiency of the equipment.

[0055] (2) Take the hinge point between the soil loosening knife and the soil loosening knife seat as the support point, so that the soil loosening monomer and the soil loosening eccentric wheel device of the soil permeability device form a cam-crank mechanism. As the eccentric wheel rotates continuously, relying on this hinge point, the soil loosening knife realizes a rhythmic reciprocating motion in the front and back directions during the forward operation of the machine. This unique motion mode, on the one hand, significantly reduces the resistance encountered during soil loosening, effectively reducing the energy consumption of the equipment; on the other hand, greatly enhances the soil loosening effect, can more fully break soil lumps, improve the soil structure, and lay a good foundation for subsequent planting or improvement work.

[0056] (3) Both the root knot-breaking vibration device and the soil loosening eccentric wheel device of the present invention adopt an adjustable eccentric structure design. By precisely adjusting the relative positions of the two groups of eccentric wheels, the cooperative operation mode of the root knot-breaking monomer and the soil loosening monomer can be changed. When synchronous operation is required, the eccentric position can be adjusted to make both start simultaneously; if intermittent operation is needed, alternating work can also be achieved through parameter adjustment.

[0057] (4) By independently adjusting the root knot-breaking vibration device or the soil loosening eccentric wheel device, the corresponding monomers show diverse motion forms, including synchronous motion, spiral intermittent motion, and grouped intermittent motion, etc. This highly flexible adjustment mechanism can accurately adjust the position parameters of the eccentric shaft according to the soil characteristics and improvement requirements of different degraded grasslands, optimize the motion combination of the root knot-breaking and soil loosening monomers, and thus achieve the best grassland improvement operation effect.

[0122] The working principle of the present invention:

[0123] Please refer to Figures 1 - 8 , the working principle of an active force grass root knot breaking and soil permeability compound operation machine is as follows. The whole machine is hung behind the tractor through the gantry 2, and the depth-limiting wheel 3 is used to adjust the soil penetration depth during the operation of the machine. The front gearbox 4 is fixedly connected to the frame A, and the rear output shaft of the tractor is connected to the front gearbox 4 through a coupling. One end of the front transmission shaft 6 is connected to the front gearbox 4 through a universal joint coupling, and the other end is connected to the side transmission mechanism 5 through a universal joint coupling.

The intermediate gearbox 7 transmits the power to the grass root knot breaking vibration devices 8 on the left and right sides through a sprocket coupling and an intermediate transmission shaft 5.

The adjacent soil loosening vibration devices 15 rotate together with the soil loosening vibration device 15 on its left through a sprocket coupling.

[0124] Please refer to Figures 9 - 11, the connecting flange 18 is fixedly connected to the side transmission mechanism 5. The side transmission mechanism 5 drives the hexagonal transmission cutter shaft 19 through the connecting flange 18. The cutter shaft connecting transmission shaft 22 is sleeved on the hexagonal transmission cutter shaft 19 to drive the bevel gear transmission shaft 23. The bevel gear transmission shaft 23 transmits power to the root-breaking and knot-untying cutter shaft 24, and then the root-breaking and knot-untying cutter shaft 24 drives the root-breaking and knot-untying flange 29 and the root-breaking and knot-untying cutter disc 30 to rotate together to achieve the root-breaking and knot-untying operation. The root-breaking and knot-untying sleeve 25 is sleeved outside the cutter shaft connecting transmission shaft 22, the bevel gear transmission shaft 23 and the root-breaking and knot-untying cutter shaft 24 to play a protective role. At the same time, the root-breaking and knot-untying sleeve 25 is connected to the hexagonal transmission cutter shaft 19 through a bearing, so that the root-breaking and knot-untying unit 21 can rotate around the hexagonal transmission cutter shaft 19. A connecting base 31 is fixed on the root-breaking and knot-untying sleeve 25. The connecting base 31 is hinged to the guide rod 33. The guide rod seat 32 is connected to the frame A. Through the pressing force applied by the spring between the connecting base 31 and the guide rod seat 32, an adaptive adjustment function is provided for the root-breaking and knot-untying unit 21. During the operation of the machine, this adjustment mechanism can enable the root-breaking and knot-untying unit 21 to automatically adjust the soil penetration depth of the root-breaking and knot-untying cutter disc 30 slightly according to the real-time change of the soil resistance.

[0125] Please refer to Figure 12 and Figure 13 , the root-breaking and knot-untying vibration device 8 is in contact with the guide rod 33 of the root-breaking and knot-untying unit 21. As the eccentric shaft 10 rotates, the root-breaking and knot-untying unit 21 makes a reciprocating motion in the vertical direction. During the mechanical advancement, the root-breaking and knot-untying device C and the root-breaking and knot-untying vibration device 8 cooperate with each other to achieve the organic combination of the horizontal displacement and the high-frequency reciprocating motion in the vertical direction of the root-breaking and knot-untying unit 21, greatly reducing the tillage resistance and significantly improving the operation efficiency and energy utilization efficiency of the equipment.

[0126] Please refer to Figure 14 and Figure 16 , the tillage device D uses the hinge point of the tillage knife 37 and the tillage knife seat 36 as the support point, so that the tillage unit 35 and the tillage vibration device 15 form a cam-crank mechanism. With the continuous rotation of the eccentric shaft 10, relying on this hinge point, the tillage knife 37 makes a rhythmic reciprocating motion in the front and back directions during the forward operation of the machine. This unique motion mode, on the one hand, significantly reduces the resistance encountered during tillage; on the other hand, it greatly enhances the tillage effect, can break soil lumps more fully, enhance the soil permeability effect, and lay a good foundation for subsequent planting or improvement work.

[0127] Both the broken root grass clump vibration device 8 and the soil loosening vibration device 15 adopt an adjustable eccentric structure design. By adjusting the relative positions of the two sets of eccentric shafts 10, the cooperative operation mode of the broken root grass clump monomer 21 and the soil loosening monomer 35 can be changed. When synchronous operation is required, the eccentric positions can be adjusted to start both of them at the same time; if intermittent operation is needed, alternating work can also be achieved through parameter adjustment. Moreover, by independently adjusting the broken root grass clump vibration device 8 or the soil loosening vibration device 15, the corresponding monomers can present diverse motion forms, including synchronous motion, spiral intermittent motion, and grouped intermittent motion and other modes. According to the soil characteristics and improvement requirements of different degraded grasslands, the motion combinations of the broken root grass clump monomer 21 and the soil loosening monomer 35 are optimized, so as to achieve the best grassland improvement operation effect.
