Description

Technical Field

[0001] The utility model relates to the technical field of mechanized farming equipment, in particular to a soil loosening device for planting. Background Art

[0002] The soil loosening device for planting loosens the soil through mechanical means, improves its structure and aeration, promotes root development and water penetration, reduces soil erosion, facilitates sowing and transplanting, controls weeds, and optimizes fertilization effects. It is usually integrated with a tractor to achieve large-scale and rapid operations, improve agricultural production efficiency, support modern and sustainable agricultural development, ensure healthy crop growth and increase yields.

[0003] In order to efficiently break up the soil, reduce forward resistance and ensure uniform loosening of the soil, today's loosening devices rotate the loosening blade at high speed.

[0004] However, when the loosening knife encounters hard rock, it will continue to rotate at high speed, and then the loosening knife will hit the hard rock. In the mildest case, the tool will be damaged, reducing the effect of crushing the soil. In the worst case, the loosening knife will stop rotating due to the obstruction of the rock, causing the motor to overcurrent and burn out, reducing the service life of the equipment.

[0008] As a preferred implementation, the plurality of swing blocks fit with the arc-shaped surfaces of the plurality of limit rods, and the swing blocks can drive the limit rods to rotate when they rotate.

[0009] As a preferred embodiment, the bottom of the moving block is provided with moving wheels to facilitate the moving block to move on the ground.

[0024] A dual-axis motor 14 is fixedly connected to one side of the top of the moving block 1 near the rotating shaft 2 3. The dual-axis motor 14 is provided with two rotating shafts 15 through the output shaft. The outer surfaces of the two rotating shafts 15 are fixedly installed with pulleys 16. The outer surfaces of the two pulleys 16 are both connected to transmission belts 17. The inner surfaces of the two transmission belts 17 are both connected to pulleys 2 18 to avoid damage to the loosening blade 13 due to overload operation. This design reduces the wear of expensive parts, prolongs the service life of the loosening blade 13, and reduces the maintenance and replacement costs of the loosening blade 13, ensuring that the machine can operate safely and stably in complex terrain to a certain extent.

[0025] like Figure 1-4 As shown, the plurality of swing blocks 9 fit with the arc-shaped surfaces of the plurality of limit rods 6 , and the swing blocks 9 can drive the limit rods 6 to rotate when rotating, so that the limit rods 6 drive the rotating blocks 5 to rotate.

[0026] like Figure 1-4 As shown, a moving wheel is provided at the bottom of the moving block 1 to facilitate the movement of the moving block 1 .

[0027] like Figure 1-4 As shown, a protective cover 20 is fixedly connected to one side of the top of the moving block 1 close to the rotating shaft 15, and the rotating shaft 15 is movably embedded in the inner surface of the protective cover 20. The protective cover 20 can prevent dust from affecting the normal operation of the dual-axis motor 14, thereby improving the service life of the dual-axis motor 14 to a certain extent.

[0028] like Figure 1-4 As shown, the inner surfaces of the plurality of swing blocks 9 are movably embedded with fixing rods 10, and the plurality of fixing rods 10 are fixedly connected to the outer surfaces of the plurality of driving blocks 4.

[0029] like Figure 1-4 As shown, a handle 19 is fixedly installed on the side of the moving block 1 away from the second rotating shaft 3, and the handle 19 provides power for the movement of the moving block 1.

[0030] like Figure 1-4 As shown, two pulleys 18 are fixedly mounted on the outer surface of the rotating shaft 3 near both ends. The pulleys 18 can transmit the power of the transmission belt 17 to the rotating shaft 3 to make the rotating shaft 3 rotate.

[0031] Working principle: This equipment is a soil loosening device for planting. The protective cover 2 can prevent the user from operating it incorrectly and causing inconvenience to the user. The protective cover 20 can prevent dust from affecting the normal operation of the dual-axis motor 14, thereby improving the service life of the dual-axis motor 14 to a certain extent.

[0032] When in use, the dual-axis motor 14 is started, and the dual-axis motor 14 drives the rotating shaft 15 to rotate through the output shaft, and the rotating shaft 15 drives the transmission belt 17 to rotate through the pulley 16, and the transmission belt 17 drives the rotating shaft 2 3 to rotate through the pulley 2 18, and the rotating shaft 2 3 drives the driving block 4 to rotate, and the driving block 4 indirectly drives the limiting rod 6 to rotate, and the limiting rod 6 drives the fixed block 11 to rotate through the rotating block 5, and the fixed block 11 drives the loosening knife 13 to rotate through the cross plate 12, and then the user manually pulls the handle 19 to make the moving block 1 move on the ground using the moving wheels, and the rotation of the loosening knife 13 can turn up the soil to loosen the soil.

[0033] When the loosening knife 13 hits the rock, the loosening knife 13 will stop rotating, and then the cross plate 12, the fixed block 11 and the rotating block 5 will stop rotating, and then the limit rod 6 will stop rotating, and then the swing block 9 will make a circular motion with the fixed rod 10 as the center, and then the swing block 9 will squeeze the spring 8 on the fixed plate 7, so that the spring 8 obtains elastic potential energy, and when the loosening knife 13 no longer touches the rock, the spring 8 releases the elastic potential energy, so that the swing block 9 continues to fit with the limit rod 6, so that the rotating block 5 can continue to indirectly drive the driving block 4 to rotate under the drive of the rotating shaft 2 3, so that the loosening knife 13 continues to turn up the soil to loosen the soil.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
