Description

Technical Field

[0001] This invention relates to the field of soil remediation device technology, specifically a soil loosening device for municipal landscaping soil remediation. Background Technology

[0002] Soil remediation is a technical measure to restore polluted soil to its normal function. Currently, urban soil pollution is severe due to the discharge of sewage, grease, acids, alkalis, and salts from normal human activities, as well as long-term irrigation with sewage and application of sludge, atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides. Although soil has a certain self-purification capacity, the pollutants exceed the soil's carrying capacity and purification rate, affecting plant growth. In order to enable plants in urban parks to grow normally, it is necessary to remediate the soil in parks and restore it to its original state.

[0003] The existing soil loosening devices have gradually revealed their shortcomings during use, mainly in the following aspects:

[0004] First, existing soil loosening devices mainly break up the soil by rotating blades. However, there are gaps between adjacent blades in the blade set, so the broken soil contains large soil clumps, resulting in incomplete soil breaking. When mixed with soil remediation particles, the soil and soil remediation particles are not mixed evenly, which affects the soil remediation effect.

[0005] Secondly, after the existing soil loosening device breaks up the soil, soil remediation particles need to be added to the broken soil manually or by equipment. Manual addition is not only inefficient but also prone to uneven distribution, which affects the effect of soil remediation. Using equipment to add the particles requires workers to operate the equipment to add them to the broken soil again, resulting in low efficiency of soil remediation. Furthermore, the amount of soil remediation particles added to the soil cannot be controlled according to the usage requirements, resulting in low practicality of the device.

[0006] Third, in the process of soil remediation using existing soil loosening devices, some areas have uneven terrain, and the existing devices do not have the function of leveling the soil. Therefore, workers need to use equipment to level the remediated soil, which makes the soil remediation process cumbersome and inefficient.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a soil loosening device for municipal landscaping soil remediation. This device can quickly break up the soil with uniform crushing effect, improve the mixing uniformity of soil remediation particles with the soil, and improve the soil remediation effect.

[0009] The device can also automatically deliver soil remediation particles to the crushed soil during the uniform crushing process. Not only is the delivery uniform, but the delivery amount can also be adjusted in real time according to the usage requirements, which improves the efficiency and effect of soil remediation.

[0010] The device can also automatically and quickly level soil that has been crushed and inoculated with soil remediation particles, further improving the efficiency of soil remediation and enhancing the device's practicality.

[0011] To address the above problems, the present invention provides the following technical solution:

[0012] A soil loosening device for municipal landscaping soil remediation includes a movable base, with a crushing mechanism and a pulverizing component mounted on top of the base.

[0013] The crushing mechanism can perform preliminary crushing of the soil and quickly transport the pre-crushed soil to the pulverizing component; the pulverizing component can quickly pulverize the soil and achieve uniform pulverization.

[0014] The pulverizing assembly includes a horizontally fixed pulverizing tank, a rotating shaft coaxially disposed inside the pulverizing tank, the rotating shaft also being horizontally reciprocating, and a plurality of pulverizing blades evenly distributed along the circumference of the rotating shaft.

[0015] A vertically positioned feeding hopper is fixedly mounted on the top of the base. The upper end of the feeding hopper extends upward and is fixedly connected to the lower outer wall of the crushing tank. The lower end of the feeding hopper extends downward and passes through the base. Several feeding holes are provided through the lower outer wall of the crushing tank located inside the feeding hopper.

[0016] The rotating and horizontally reciprocating pulverizer can not only quickly pulverize the soil in the pulverizer, but also move the soil back and forth in the pulverizer, so that soil with qualified particle size can be evenly scattered to the ground through the discharge hole.

[0017] As an optimized solution, the crushing mechanism includes a vertically lifting platform, a fixed plate fixedly connected to the platform below it, a sliding U-shaped plate horizontally reciprocating at the bottom of the fixed plate, a driven shaft rotating along a horizontal line on the inner wall of the sliding U-shaped plate, and a plurality of crushing spikes evenly distributed along the circumference of the driven shaft.

[0018] The bottom of the lifting platform is also equipped with a punching assembly and a feeding assembly, which are located on the front and rear sides of the sliding U-shaped plate, respectively.

[0019] A rectangular groove is provided through the top of the base. When the lifting platform is lowered to the lowest position, the feeding ends of the crushing nail teeth, the punching assembly and the feeding assembly all pass through the rectangular groove and are inserted into the soil. The discharging end of the feeding assembly is connected to the crushing tank.

[0020] As an optimized solution: the feeding assembly includes a protective shell and a feeding channel fixedly connected to the lifting platform. The protective shell is connected to the feeding end of the feeding channel. An opening is provided on the outer wall of the protective shell, and a drive shaft rotatably arranged along a horizontal line is provided on the inner wall of the protective shell. A plurality of feeding plates are evenly distributed along the circumference of the drive shaft. During the rotation of the feeding plates, they can rub against the inner wall of the protective shell.

[0021] The feeding channel is equipped with a rotating conveyor belt, and the surface of the conveyor belt is evenly distributed with several fixed baffles along its rotation trajectory.

[0022] The upper outer wall of the crushing tank is provided with a feed inlet. When the feeding channel is lowered to the lowest position, its discharge end is connected to the feed inlet of the crushing tank.

[0023] As an optimized solution, the punching assembly includes a front plate fixedly connected to a lifting platform. A transition U-shaped plate is horizontally slidable at one end of the front plate. Vertically reciprocating lifting blocks are provided at opposite ends of the transition U-shaped plate. A lifting plate fixedly connected to the two lifting blocks is located below the transition U-shaped plate. Several vertically arranged impact nail teeth are fixedly provided at the bottom of the lifting plate.

[0024] The impact nail teeth can punch holes in the soil, and the crushing nail teeth offer less resistance when crushing the already punched soil, thereby accelerating the crushing speed of the soil.

[0025] As an optimized solution, both ends of the pulverizing tank are coaxially provided with rotating columns, and the opposing ends of the two rotating columns extend into the pulverizing tank. Each end of the rotating column is provided with a sliding column that is slidably connected to it, and both ends of the rotating shaft are coaxially fixed to the two sliding columns.

[0026] As an optimized solution, the top of the fixed plate is provided with a sliding groove, and a sliding block is provided in the sliding groove for horizontal reciprocating movement. The sliding block is fixedly connected to the sliding U-shaped plate.

[0027] As an optimized solution, the inner walls of the transition U-shaped plate are fixed to the same fixing block, and the ends of the front plate are fixed to two horizontally arranged insert rods. One end of each insert rod passes through the fixing block and is slidably connected to the fixing block.

[0028] As an optimized solution, the top of the base is also fixedly equipped with a material spreading component that communicates with the inner cavity of the hopper. The material spreading component can automatically feed particles into the hopper, which not only feeds them evenly, but also allows for real-time adjustment of the feeding amount.

[0029] The material dispensing assembly includes a fixedly mounted receiving box with an open bottom. A connecting hopper is fixedly connected to the open end of the receiving box. A dispensing box, connected to the dispensing hopper, is fixedly mounted below the receiving box. A horizontally mounted fixed arc-shaped plate is fixedly mounted on the inner top of the dispensing box, with opposite sidewalls of the fixed arc-shaped plate abutting against the opposite inner walls of the dispensing box. The lower end of the connecting hopper passes through the dispensing box and is fixedly connected to the inner wall of the fixed arc-shaped plate.

[0030] The feeding box is equipped with a rotating arc plate that rotates along the axis of the fixed arc plate. The inner wall of the rotating arc plate is in frictional contact with the outer wall of the fixed arc plate. The outer wall of the rotating arc plate is provided with several clearance grooves extending along its axial direction. The outer wall of the fixed arc plate is provided with several through holes evenly distributed along its axial direction. When the rotating arc plate rotates, the overlap area between the through holes and the clearance grooves changes, thereby adjusting the amount of soil remediation particles to be dispensed.

[0031] As an optimized solution, the lower port of the connecting bucket is provided with a rotating rod that rotates along the horizontal line. Several stirring blades are evenly distributed along the circumference of the rotating rod. During the rotation of the stirring blades, the soil remediation particles in the container can be prevented from clogging.

[0032] As an optimized solution, a leveling component is provided on the rear side of the base, which can quickly level the crushed soil.

[0033] The smoothing assembly includes a vertically lifting smoothing plate with a U-shaped cross-section and the U-shaped opening facing the base. A transmission shaft is provided in the area enclosed by the smoothing plate and rotates along a vertical line. Several soil-removing plates are evenly distributed along the circumference of the transmission shaft. During the rotation of the soil-removing plates, they can rub against the inner wall of the smoothing plate.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. The crushing mechanism can initially crush the soil and quickly transport the crushed soil to the pulverizing component.

[0107] A connecting bracket 82 is fixedly provided on the top of the base 1. One end of the connecting bracket 82 extends to the outside of the base 1 and is fixedly connected to two downwardly arranged second telescopic cylinders 83. The telescopic ends of the second telescopic cylinders 83 are fixedly connected to the top plate 85.

[0108] The base 1 is provided with several rotating wheels 14, and the connecting bracket 82 is fixed with two handrails 9.

[0109] The first belt drive assembly 63, the second belt drive assembly 21, and the third belt drive assembly 43 are all composed of a drive wheel 87, a driven wheel 88, a transmission belt 89, and a control motor 90. The drive wheel 87 is connected to the driven wheel 88 through the transmission belt 89, and the output end of the control motor 90 is fixedly connected to the drive wheel 87.

[0110] The working principle of this device is as follows:

[0111] When the soil is being repaired, the first telescopic cylinder 3 extends and lowers the lifting platform 2 to its lowest position. The device is moved by the rotating wheel 14 and the handrail 9. The first belt drive assembly 63 drives the two third reciprocating screws 18 to rotate, which in turn drives the two lifting blocks 20 to slide vertically back and forth, thereby controlling the lifting plate 16 and several impact nail teeth 15 to move vertically back and forth. During the descent of the impact nail teeth 15, they gradually insert into the soil. At the same time, the fixed block 24 slides horizontally with the transition U-shaped plate 22, thereby ensuring that the impact nail teeth 15 remain vertically moving during the forward movement of the device. After the impact nail teeth 15 descend to the lowest position, they rise. When the impact nail teeth 15 rise to the point of separation from the soil, they are reset under the pull of the tension spring 26. After being reset, the impact nail teeth 15 repeat the above process, thereby continuously punching holes in the soil, reducing the resistance of the crushing nail teeth 28 to the soil crushing, and accelerating the soil crushing speed.

[0112] During the initial crushing of the soil, the second drive motor 35 drives the second reciprocating screw 34 to rotate, which in turn drives the sliding block 33, the sliding U-shaped plate 29, the driven shaft 27, and the crushing nail teeth 28 to perform horizontal reciprocating motion. At the same time, the first built-in motor 37 drives the driven shaft 27 and the crushing nail teeth 28 to rotate, thereby initially crushing the soil after punching. The second built-in motor 45 drives the drive shaft 38 and the feeding plate 39 to rotate. The feeding plate 39 transports the initially crushed soil into the protective shell 40 and enters the feeding channel 42 through the connection between the protective shell 40 and the feeding channel 42. The second belt drive assembly 21 drives the drive roller 48 and the driven roller 44 to rotate, which in turn drives the conveyor belt 47 and the baffle 49 to rotate. With the cooperation of the baffle 49, the conveyor belt transports the soil at the bottom of the feeding channel 42 to the discharge end of the feeding channel 42. The soil at the discharge end of the feeding channel 42 is crushed through the feed inlet 56. Inside the tank 53, the first drive motor 61 drives the sliding column 59, the rotating shaft 54, and the crushing blade 55 to rotate. At the same time, the first belt drive assembly 63 drives the two first reciprocating screws 58 to rotate, thereby driving the two moving blocks 57 to slide horizontally back and forth. With the cooperation of the swing plate 62, the control plate 60, the sliding column 59, the rotating shaft 54, and the crushing blade 55 are driven to move horizontally back and forth. The crushing blade 55 crushes the soil in the crushing tank 53. Soil with qualified particle size enters the discharge hopper 50 through the discharge hole 64 and then falls to the ground. The rotating and horizontally reciprocating crushing blade 55 can not only quickly crush the soil in the crushing tank 53, but also move the soil in the crushing tank 53 back and forth, so that the soil with qualified particle size is evenly scattered to the ground through the discharge hole 64. This achieves the function of uniformly crushing the soil, improves the mixing uniformity of soil remediation particles and soil, and improves the soil remediation effect.

[0113] As the crushed soil is poured downwards through the hopper 50, the soil remediation particles in the receiving box 65 enter the fixed arc plate 76 through the connecting hopper 73. The soil remediation particles in the fixed arc plate 76 then pass through the through hole 79 of the fixed arc plate 76, the clearance groove 78 of the rotating arc plate 77, and the connecting pipe 71 before entering the hopper 50, where they mix with the downwardly poured soil. The fourth drive motor 66 drives the rotating rod 75 and the stirring plate 74 to rotate, thereby stirring the soil remediation particles in the receiving box 65, the connecting hopper 73, and the fixed arc plate 76. To prevent blockage, the soil remediation particles are evenly fed into the hopper 50 and mixed with the soil. When adjusting the amount of soil remediation particles, the third drive motor 70 drives the drive gear 69, the semi-tooth ring 68 and the rotating arc plate 77 to rotate, thereby adjusting the overlapping area of ​​the clearance groove 78 and the through hole 79, thus adjusting the amount of soil remediation particles. This realizes the function of automatically and evenly distributing soil remediation particles into the crushed soil, and can also adjust the amount of particles in real time according to the usage requirements, improving the soil remediation efficiency and effect.

[0114] When leveling the broken soil and the soil remediation particles that have been applied, the second telescopic cylinder 83 drives the top plate 85 and the smearing plate 86 to descend until the bottom of the smearing plate 86 is lowered to the height required for leveling the soil. During the forward movement of the device, the fifth drive motor 84 drives the transmission shaft 81 and the soil-pushing plate 80 to rotate. The rotating soil-pushing plate 80 can quickly level the soil in the smearing plate 86, further improving the soil remediation efficiency and the practicality of the device.
