[0044] The working principle of the present application is as follows:

[0045] First, the device is fixed in the subsoiler vehicle head, then according to the soil estimation of the area to be loosened, the initial rotating speed of the first motor 37 and the third motor 357 is preset through the PLC controller, the reciprocating motion speed of the reciprocating loosening head 33 and the working frequency of the auxiliary loosening tooth 352 are determined;

[0046] First, a trench is dug on the ground for placing the reciprocating loosening head 33 and the detection loosening head 34 in the trench, then the second motor 53 is started, the output end of the second motor 53 drives the rotating rod 56 to rotate 90 degrees, so that the rotating plate 55 on the outer wall of the rotating rod 56 rotates, and the loosening roller 51 also enters the trench.

[0047] The loosening device can be moved forward under the driving of the loosening vehicle head, so that the soil can be initially loosened by the detection loosening head 34, and the first motor 37 is started (the first motor 37 is set to rotate forward for 30 seconds and then reverse cyclically), the output end of the first motor 37 drives the threaded rod 38 to rotate, since the threaded rod 38 penetrates the plurality of threaded blocks 32 in sequence, under the action of threaded transmission, the threaded block 32 moves in a reciprocating straight line in the sliding groove 31 along the axial direction of the threaded rod 38, thereby driving the reciprocating loosening head fixed to the bottom end to move synchronously, and the reciprocating loosening head moves forward under the driving of the loosening vehicle head, the reciprocating motion enables the loosening head to cover a wider area in the transverse direction, and each reciprocation can loosen the soil in a certain width; combined with the forward movement for overall loosening of the soil, the situation of missed loosening or uneven loosening is avoided, and the large area to be loosened can be fully treated;

[0048] During the movement of the reciprocating soil loosening head 33, the third motor 357 drives the push plate 358 to rotate, and the push plate 358 intermittently hits the impact block 3510 at both ends, so that the supporting plate 359, the sliding column 355 and the auxiliary soil loosening tooth 352 move up and down in the arc-shaped moving groove 351, the limiting plates 3514 are staggered on both sides of the sliding column 355, the swing of the sliding column 355 is limited, the auxiliary soil loosening tooth 352 stably assists in loosening the soil, the flexible rubber sheet 356 can seal the arc-shaped moving groove 351 and does not affect the movement of the auxiliary soil loosening tooth 352, and the fourth motor 54 is started, the soil loosening roller 51 is driven to rotate by the fourth motor 54, and the soil loosened for the first time is loosened again, so that the loosening effect of the soil is greatly improved, and good soil conditions are created for subsequent landscaping and planting work.

[0049] During the process that the detection soil loosening head 34 initially loosens the soil, the detection mechanism 4 plays a key role in detecting the hardness of the soil: when the detection soil loosening head 34 contacts the soil and is subjected to the resistance of the soil, the detection soil loosening head 34 swings backward, the top end of the detection soil loosening head 34 and the bottom end of the detection head are reversely moved (tilted to the direction of the moving direction of the soil loosening vehicle head) through the lever principle, the movement of the top end of the detection soil loosening head 34 is transmitted to the connecting rod 44 through the transmission structure composed of the second adjusting frame 410, the pull rod 49 and the first adjusting frame 48, and the first adjusting frame 48 is slidably connected in the adjusting groove 47, and the pull rod 49 is hingedly connected with the second adjusting frame 410 and the first adjusting frame 48, so that the swing of the top end of the detection soil loosening head 34 can be effectively converted into the linear motion of the connecting rod 44;

[0050] After receiving the force, the push plate 43 in the airtight box 41 slides away from the detection soil loosening head 34 under the airtight guide of the connecting port 42, the push plate 43 extrudes the detection spring 45, and at the same time, the oil in the airtight box 41 is extruded into the detection box 411 through the oil outlet 412, the greater the hardness of the soil, the greater the resistance received by the detection soil loosening head 34, and based on the force amplification of the lever, the greater the force transmitted by the top end of the detection soil loosening head 34 to the connecting rod 44, and the farther the sliding distance of the push plate 43 in the airtight box 41, wherein the repulsive force of the electromagnet on the permanent magnet plate 415 is set according to the hardness of the soil in advance, that is, in the most soft soil, the hydraulic oil does not enter the detection box 411, and as the soil becomes harder, the hydraulic oil gradually enters the detection box 411.

[0051] Before the soil loosening starts, the oil pump 419 is started every time to extract the hydraulic oil from the hydraulic oil tank 418 through the PLC controller, and the hydraulic oil is delivered into each airtight box 41 through the shunt pipe 420 and the oil inlet, and the amount of the hydraulic oil in each box is consistent.

[0052] After the oil enters the detection box 411, the permanent magnet plate 415 is pushed to slide in the detection box 411, the distance between the permanent magnet plate 415 and the electromagnetic block 413 is changed, the laser range finder 417 monitors the distance in real time, and the signal is transmitted to the PLC controller. The PLC controller converts the distance into soil hardness through the existing calculation model, and the PLC controller sets the preset value (different preset values for different soil conditions) according to the estimated soil condition of the loosening area. After comparing the actual soil hardness value with the preset value, the corresponding adjustment is carried out.

[0053] If the actual soil hardness value is less than the preset value: it means that the current soil is relatively soft, and there is no need for excessive loosening. In order to avoid energy waste and unnecessary damage to the soil structure, the PLC controller reduces the speed of the first motor 37, slows down the reciprocating motion of the reciprocating loosening head 33, and reduces the frequency of soil turning; at the same time, the speed of the third motor 357 is reduced, the working strength of the auxiliary loosening tooth 352 is reduced, and the frequency of its up and down reciprocating movement is reduced; the speed of the fourth motor 54 is also appropriately reduced, so that the loosening roller 51 rotates at a slower speed, and the soil is gently loosened again, which protects the original structure of the soil and maintains the ecological balance of the soil while ensuring the loosening effect.

[0054] If the actual soil hardness value is equal to the preset value: it means that the soil hardness is in the expected range, and the PLC controller maintains the current speed of the first motor 37, the third motor 357 and the fourth motor 54, so that the reciprocating loosening head 33, the auxiliary loosening tooth 352 and the loosening roller 51 maintain the current working state, and the soil is loosened in an orderly manner, ensuring that the loosening task is completed at the appropriate working strength, and ensuring the stability of the operation efficiency and quality.

[0055] If the actual soil hardness value is greater than the preset value: it means that the soil is hard, and the conventional loosening intensity is difficult to achieve the ideal loosening effect. In order to effectively break the hard soil, the PLC controller greatly increases the speed of the first motor 37, speeds up the reciprocating motion of the reciprocating loosening head 33, enhances its impact and stirring ability on the soil; significantly increases the speed of the third motor 357, increases the working frequency of the auxiliary loosening tooth 352, so that it moves up and down more frequently, and further breaks the soil; at the same time, the speed of the fourth motor 54 is greatly increased, so that the loosening roller 51 rotates at a faster speed, and the soil is subjected to strong rolling and crushing, thereby effectively improving the loosening degree of the soil and creating good conditions for the growth of plant roots.

[0056] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
