Description

Technical Field

[0001] The invention relates to the technical field of garden greening soil loosening, and in particular to a soil loosening device for garden greening projects with a loosening effect. Background Art

[0002] In landscaping projects, soil loosening is a key step in ensuring healthy plant root growth and improving plant survival and growth quality. Good soil looseness effectively improves soil aeration, water permeability, and water retention, providing sufficient oxygen and water for plant roots, promoting root growth and nutrient absorption. With the rapid development of the landscaping industry, the demand for efficient and precise soil loosening technology is becoming increasingly urgent.

[0003] Existing mechanized soil loosening devices commonly suffer from uneven loosening results and an inability to adjust the loosening force in real time based on soil hardness (for example, the garden loosening device disclosed in Chinese patent CN201910123456.7 suffers from an unadjustable loosening force). These devices often employ fixed operating modes when used in different regions and soil textures. This results in excessive loosening in soft soil areas, damaging the original soil structure and wasting energy. However, they struggle to achieve the desired loosening effect in hard soil areas, impacting plant growth. Furthermore, some loosening devices are prone to missing loosening points during operation, resulting in incomplete soil loosening and reducing the quality of landscaping projects.

[0020] 2. The detection loosening head swings due to resistance when it contacts the soil. The transmission structure causes the push plate to slide in the airtight box, squeezing the detection spring and squeezing the oil into the detection box. The harder the soil, the farther the push plate slides, and the oil pushes the permanent magnet plate to move. The laser rangefinder monitors the distance between the permanent magnet plate and the electromagnetic block and transmits it to the PLC controller to convert it into a soil hardness value. The PLC controller compares this value with the preset value and makes intelligent adjustments: if the actual value is less than the preset value, the speed of each motor is reduced to reduce the loosening intensity; if it is equal to the preset value, the current speed is maintained; if it is greater than the preset value, the speed of each motor is increased to enhance the loosening capacity, thereby achieving real-time and precise adjustment of the loosening force according to the soil hardness.

[0042] A second loosening mechanism 5, comprising a loosening roller 51 for loosening the soil;

[0043] The loosening mechanism 5 also includes an extension plate 52 fixedly connected to the outer walls on both sides of the mounting column 1, wherein the outer wall of one of the extension plates 52 is fixedly connected to a second motor 53, and the output end of the second motor 53 is fixedly connected to a rotating rod 56, and the outer wall of the rotating rod 56 is fixedly connected to two symmetrical rotating plates 55, and the outer wall of one of the rotating plates 55 is fixedly connected to a fourth motor 54, and the output end of the fourth motor 54 is fixedly connected to the axis of the loosening roller 51, and the extension plate 52 and the outer walls on both sides of the mounting plate 2 are symmetrically connected to rolling wheels 57 for rotation, and the PLC controller is electrically connected to the first motor 37, the third motor 357, and the fourth motor 54 to form a regulation loop, wherein the rolling wheel 57 is to prevent the components under the mounting plate 2 from directly contacting the ground. The setting of the rolling wheel 57 will also make it easier to move the loosening device.

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

[0045] First, the device is fixed in the deep loosening locomotive head. Then, according to the estimated soil conditions of the area to be loosened, the initial speeds of the first motor 37 and the third motor 357 are preset through the PLC controller to determine the reciprocating speed of the reciprocating loosening head 33 and the operating frequency of the auxiliary loosening teeth 352.

[0046] First, a trench needs to be dug on the ground to place the reciprocating loosening head 33 and the detection loosening head 34 in the trench, and then the second motor 53 is started. Its output end 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 accordingly, causing the loosening roller 51 to also enter the trench.

[0047] Driven by the loosening head, the loosening device can be moved forward. Therefore, the soil can be loosened preliminarily by detecting the loosening head 34, and at the same time, the first motor 37 is started (the first motor 37 rotates forward for 30 seconds according to the pre-set reverse cycle), and its output end drives the threaded rod 38 to rotate. Since the threaded rod 38 passes through multiple threaded blocks 32 in sequence, under the action of the threaded transmission, the threaded block 32 performs reciprocating linear motion along the axial direction of the threaded rod 38 in the sliding groove 31, thereby driving the reciprocating loosening head fixed at its bottom end to perform reciprocating motion synchronously, and the reciprocating loosening head is driven by the loosening head to move forward. The reciprocating motion enables the loosening head to cover a wider area in the horizontal direction, and each reciprocating motion can loosen the soil within a certain width; combined with the forward movement, the soil is loosened comprehensively to avoid missing loosening or uneven loosening, ensuring that a large area of the area to be loosened can be fully processed;

[0048] During the reciprocating movement of the loosening head 33, the third motor 357 drives the dial plate 358 to rotate, and the two ends of the dial plate 358 intermittently hit the impact block 3510, so that the support plate 359, the sliding column 355 and the auxiliary loosening teeth 352 move back and forth up and down in the arc-shaped moving groove 351, and the limit plates 3514 are staggered on both sides of the sliding column 355 to limit the swing of the sliding column 355, ensuring that the auxiliary loosening teeth 352 stably loosen the soil. The flexible rubber sheet 356 can seal the arc-shaped moving groove 351 without affecting the movement of the auxiliary loosening teeth 352. At the same time, the fourth motor 54 is turned on, and the loosening roller 51 is driven to rotate by the fourth motor 54, thereby loosening the soil again after the initial loosening, greatly improving the loosening effect of the soil and creating good soil conditions for subsequent landscaping planting work.

[0049] In the process of the detection loosening head 34 taking the lead in loosening the soil, the detection mechanism 4 plays a key role in detecting the hardness of the soil: when the detection loosening head 34 contacts the soil and is subjected to soil resistance, the detection loosening head 34 is forced to swing backward, and the top of the detection loosening head 34 and the bottom of the detection head move in opposite directions (tilted in the moving direction of the loosening vehicle head) through the lever principle. The movement of the top of the detection loosening head 34 is transmitted to the connecting rod 44 through the transmission structure composed of the second adjustment frame 410, the pull rod 49 and the first adjustment frame 48. Due to the sliding fit of the first adjustment frame 48 in the adjustment slot 47, and the hinged design of the pull rod 49, the second adjustment frame 410 and the first adjustment frame 48, the swing of the top of the detection loosening head 34 can be effectively converted into a linear motion of the connecting rod 44;

[0050] After receiving the force, the connecting rod 44 pulls the push plate 43 in the airtight box 41 to slide in the direction away from the detection loosening head 34 under the airtight guide of the connecting port 42, and the push plate 43 squeezes the detection spring 45, and at the same time squeezes the oil in the airtight box 41 into the detection box 411 through the oil drain port 412. The greater the soil hardness, the greater the resistance encountered by the detection loosening head 34. Based on the force amplification effect of the lever, the greater the force transmitted to the connecting rod 44 from the top of the detection loosening head 34 is, and the farther the push plate 43 slides in the airtight box 41. The repulsive force of the electromagnet on the permanent magnet plate 415 is pre-set according to the soil hardness, that is, the hydraulic oil will not enter the detection box 411 where the soil is the softest. As the soil hardens, the hydraulic oil will gradually enter the detection box 411.

[0051] Before loosening the soil, the oil pump 419 needs to be started by the PLC controller each time to extract hydraulic oil from the hydraulic oil tank 418 and transport it to each airtight box 41 through the diversion pipe 420 and the oil inlet. The amount of hydraulic oil in each box is consistent.

[0052] After the oil enters the detection box 411, it pushes the permanent magnet plate 415 to slide inside the detection box 411, changing the distance between the permanent magnet plate 415 and the electromagnetic block 413. The laser rangefinder 417 monitors the distance between the two in real time and transmits the signal to the PLC controller. The PLC controller converts the distance into soil hardness through the existing calculation model. The PLC controller sets a preset value based on the estimated soil conditions in the area to be loosened (the preset value varies for different soil conditions). After comparing the actual soil hardness value with the preset value, the PLC controller makes targeted adjustments.

[0053] If the actual soil hardness value is less than the preset value: it means that the current soil is relatively loose and there is no need to loosen the soil excessively. In order to avoid energy waste and unnecessary damage to the soil structure, the PLC controller will reduce the speed of the first motor 37, slow down the reciprocating motion speed of the reciprocating loosening head 33, and reduce the frequency of turning the soil; at the same time, reduce the speed of the third motor 357, weaken the working intensity of the auxiliary loosening teeth 352, and reduce the frequency of its up and down reciprocating movement; for the fourth motor 54, the speed is also appropriately reduced, so that the loosening roller 51 rotates at a slower speed, and the soil is loosened gently again. While ensuring the loosening effect, the original structure of the soil is protected and the ecological balance of the soil is maintained.

[0054] If the actual soil hardness value is equal to the preset value: it indicates that the soil hardness is within the expected range. At this time, 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 teeth 352 and the loosening roller 51 maintain the current working state, and loosen the soil step by step to ensure that the loosening task is completed under appropriate work intensity, and to ensure the stability of work efficiency and quality.

[0055] If the actual soil hardness value is greater than the preset value: it means that the soil is relatively hard, and conventional loosening force is difficult to achieve the ideal loosening effect. In order to effectively crush the hard soil, the PLC controller will greatly increase the speed of the first motor 37, speed up the reciprocating speed of the reciprocating loosening head 33, and enhance its impact and stirring ability on the soil; significantly increase the speed of the third motor 357, and increase the working frequency of the auxiliary loosening teeth 352, so that it moves up and down more frequently to further crush the soil; at the same time, greatly increase the speed of the fourth motor 54, so that the loosening roller 51 rotates at a faster speed, and the soil is strongly crushed and crushed, thereby effectively improving the looseness of the soil and creating good conditions for the growth of plant roots.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
