Description

Technical Field

[0001] The present invention relates to the field of contaminated soil treatment, and in particular to a contaminated soil treatment device and a soil treatment method thereof. Background Art

[0002] Soil is a strategic resource for human survival and national prosperity. With the rapid development of industrialization, urbanization and agricultural intensification, a large amount of untreated waste is transferred to the soil system and is collected and remains in the soil environment under the influence of natural factors.

[0003] One of the traditional ways to repair contaminated soil is to use a tiller to dig up the soil, and then sprinkle drugs on the turned up soil, using the drugs to blend with the soil to change the soil properties and achieve the purpose of soil repair. However, the traditional tiller generally uses a crankshaft to drive a pointed shovel to dig the soil. The efficiency of turning the soil is extremely fast, but the soil turned up by this digging method is generally a large clod. If soil remediation drugs are sprayed directly on such a large clod, the binding force between the drug and the soil will decrease, which will lead to a decrease in the drug's repair power. Therefore, the turned up clods are generally crushed again, but this will increase the workload of the staff. Therefore, there is a need for a soil remediation device that can dig the soil with a traditional tiller and directly crush the dug clods. Summary of the invention

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] refer to Figures 1 to 10 ;

[0038] A contaminated soil treatment device includes a tractor 1 and a lifter 2 arranged at the rear of the tractor 1, and further includes:

[0039] The earth-moving component 3 includes a support frame 4 connected to the lifter 2, a power transmitter 5 arranged on the support frame 4, a support long rod 6 connected to the support frame 4, a plurality of connecting plates 7 evenly distributed along the length direction of the support long rod 6, a support cross bar 9 arranged above each two connecting plates 7 and fixedly arranged on the support long rod 6 and the support frame 4 at both ends, and an earth-breaking component 12 arranged between each two connecting plates 7, each of the connecting plates 7 is provided with a rotating shaft 8, one end of the power transmitter 5 is connected to the rear wheel of the tractor 1 through a universal transmission shaft One end of the driving rod 16 is connected to the power shaft, and the other end is connected to a rotating shaft 8 arranged in the middle of the support frame 4. Each of the earth-moving components 3 includes a swinger 13 connected to each rotating shaft 8, a transmission rod 16 connected to the swinger 13, and a rotary crushing mechanism 23 arranged in each swinger 13. One end of the transmission rod 16 is coaxially fixed to the rotating shaft 8 and the other end is hinged to the swinger 13. Each of the rotary crushing mechanisms 23 includes a rotary transmission device 26 arranged in the swinger 13 and a soil-breaking knife 24 connected to the rotary transmission device 26.

[0040] The medicine storage box 43 is arranged above the earth-moving component 3.

[0041] When the device is running, the staff first puts the soil treatment drugs needed into the drug storage box 43, then starts the tractor 1, and adjusts the height of the entire digging component 3 from the ground through the lifter 2. After the adjustment is appropriate, the tractor 1 moves forward with the entire digging component 3. At this time, the power transmitter 5 transmits power to the rotating shaft 8, and all the rotating shafts 8 are driven to rotate. Each rotating shaft 8 drives two transmission rods 16 to rotate, and all the transmission rods 16 drive the oscillators 13 connected thereto to move. All the oscillators 13 are driven by the rotating shaft 8 to form a crank-like rotation, so that all the oscillators 13 swing alternately around the hinge with the transmission rod 16. When the oscillator 13 is driven to rotate from the middle position to the lowest point from the ground, it will drive the earth-breaking knife 24 to rotate and insert into the soil through the rotating transmission 26. In the soil, as the oscillator 13 is continuously driven by the transmission rod 16, the movement of the oscillator 13 will cause the soil-breaking knife 24 inserted into the soil to be pulled out of the soil. In this process, the rotating transmission device 26 will drive the soil-breaking knife 24 to rotate in the opposite direction and pull it out of the soil. As the tractor 1 continues to move forward, the soil-breaking knife 24 is continuously driven to be inserted into the soil in a forward rotation manner and pulled out of the soil in a reverse rotation manner. The rotation of the soil-breaking knife 24 breaks up the large soil lumps brought out when being pulled out, so that the soil turning depth is deep enough and the large lumps of soil turned out are broken at the same time, which greatly improves the work efficiency. When digging, the treatment medicine is applied to the treated soil through the medicine storage box 43, and the large lumps in the soil are removed, so that the medicine and the soil are fully combined, and the effect of soil treatment is also greatly improved.

[0042] In order to ensure that the structure of the transmission rod 16 and the oscillator 13 is displayed, the following features are specifically provided:

[0043] Each of the oscillators 13 includes a mounting shell 14 , in which the rotary transmission device 26 is disposed. The top of the mounting shell 14 is symmetrically provided with two adapters 15 , and one end of each adapter 15 is hinged to one end of a transmission rod 16 .

[0044] When the device is running, the rotating shaft 8 is driven to rotate, thereby causing the transmission rod 16 to rotate around one end fixed to the rotating shaft 8. The rotation of the transmission rod 16 drives the mounting shell 14 to swing through the adapter seat 15 hingedly connected to it, thereby driving the earth-breaking knife 24 connected to the rotating transmission device 26 to swing.

[0045] In order to show the detailed structure of the oscillator 13, the following features are specifically provided:

[0046] The excavating component 3 also includes a supporting base plate 10 fixedly arranged on the supporting frame 4, and a plurality of supporting bases 11 of the same number as the earth-breaking component 12 are evenly arranged on the supporting base plate 10 along its axis. Each of the oscillators 13 also includes a U-shaped bracket 21 connected to a supporting base 11, a first connecting shaft 18 penetrating and rotatably arranged at the end of the U-shaped bracket 21, a second connecting shaft 22 penetrating and rotatably arranged at the other end of the U-shaped bracket 21, and a swing plate 19 coaxially rotatably arranged on the second connecting shaft 22. The U-shaped bracket 21 is hingedly connected to the supporting base plate 10 through the first connecting shaft 18, a through hole 20 is opened on the swing plate 19, the mounting shell 14 penetrates the through hole 20, and two limiting brackets 17 are symmetrically arranged along the through hole 20 on the swing plate 19, and one side of each limiting bracket 17 is fixedly connected to the mounting shell 14 and the other bottom surface is fixedly connected to the swing plate 19.

[0047] When the device is running, the transmission rod 16 drives the mounting shell 14 to swing. Under the limit of the mounting shell 14 by the swing plate 19, the swing of the mounting shell 14 drives the swing plate 19 to swing back and forth. The swing plate 19 drives the U-shaped bracket 21 to swing back and forth around the first connecting shaft 18 through the second connecting shaft 22 on the U-shaped bracket 21, causing the soil-breaking knife 24 connected to the rotary transmission device 26 to reciprocately insert and pull out the soil, thereby achieving the soil turning effect.

[0048] In order to show the detailed structure of the rotary crushing mechanism 23, the following features are specifically provided:

[0049] Each of the rotating crushing mechanisms 23 also includes a rolling shaft 25 rotatably disposed in the mounting shell 14, a first bevel tooth 33 coaxially disposed on the rolling shaft 25, a transfer support seat 34 disposed below the rolling shaft 25 and fixedly connected to the inner wall of the mounting shell 14, a connecting shaft 36 rotatably disposed in the middle of the transfer support seat 34, and a second bevel tooth 35 coaxially fixedly disposed at the end of the connecting shaft 36, the first bevel tooth 33 and the second bevel tooth 35 are meshed, and the earth-breaking knife 24 is connected to the connecting shaft 36.

[0050] When the device is running, the rolling shaft 25 is driven to rotate by the rotary transmission 26, the rolling shaft 25 drives the first bevel gear 33 to rotate, the first bevel gear 33 drives the second bevel gear 35 to rotate, the second bevel gear 35 drives the connecting shaft 36 to rotate, and the connecting shaft 36 drives the earth-breaking knife 24 to rotate, so that when the device is working, the earth-breaking knife 24 can rotate when it is inserted and pulled back and forth in the soil.

[0051] In order to ensure that the rolling shaft 25 can be driven to rotate by the rotary transmission 26 when the device is running, the following features are specifically provided:

[0052] Each of the rotating transmission devices 26 includes a winding wheel 30 coaxially arranged on the rolling shaft 25, a resetter 27 coaxially arranged on the rolling shaft 25, a steel rope 31 wound around the winding wheel 30, and a rope rack 32 fixedly arranged on a corresponding supporting cross bar 9 located above the mounting shell 14, wherein one end of the steel rope 31 is fixedly arranged on the rope rack 32 and the other end is wound around the winding wheel 30.

[0053] It should also be noted that the steel rope 31 is always in a taut state under the action of the winding wheel 30. When the earth-breaking knife 24 is inserted into the soil, since the steel rope 31 is in a taut state, the winding wheel 30 is driven away from the rope rack 32. At this time, the winding wheel 30 is driven to release the steel rope 31, thereby driving the rolling shaft 25 to rotate, and the resetter 27 is tightened by force, causing the earth-breaking knife 24 connected below to rotate. When the earth-breaking knife 24 is pulled out of the soil, the winding wheel 30 is driven close to the rope rack 32, and the steel rope 31 will relax at this time, but as the resetter 27 starts to drive the rolling shaft 25 to rotate in the opposite direction, the rolling shaft 25 drives the winding wheel 30 to rotate in the opposite direction, thereby tightening the relaxed steel rope 31 again, and the reverse rotation of the rolling shaft 25 also drives the earth-breaking knife 24 connected below to rotate in the opposite direction.

[0054] In order to show the detailed structure of the resetter 27, the following features are specifically provided:

[0055] The resetter 27 includes a positioning box 28 fixedly disposed on a side wall of the mounting shell 14 and a spring leaf 29 disposed in the positioning box 28 . One end of the spring leaf 29 abuts against the positioning box 28 , and the other end is fixedly connected to the rolling shaft 25 . The rolling shaft 25 passes through the positioning box 28 .

[0056] When the earth-breaking knife 24 is extended into the soil, the winding wheel 30 drives the rolling shaft 25 to rotate, and the spring leaf 29 is driven to be wound. When the earth-breaking knife 24 is pulled out of the soil, the spring leaf 29 is reset to drive the rolling shaft 25 to rotate in the opposite direction.

[0057] In order to ensure that the connecting shaft 36 can provide a more stable downward driving force when driving the earth-breaking blade 24 to rotate downward and insert into the soil during operation of the device, the following features are specifically provided:

[0058] A reinforcement shaft 39 is coaxially fixedly arranged on the connecting shaft 36, and a stepped shaft 40 is also arranged on the reinforcement shaft 39. Two adapter circular plates 37 are symmetrically arranged at both ends of the stepped shaft 40, and a protective outer sleeve 42 is fixedly arranged between the two adapter circular plates 37. One end of each of the adapter circular plates 37 abuts against the outer ring wall of a ball bearing 38, and the two ends of the stepped shaft 40 respectively abut against the inner ring wall of a ball bearing 38. The two ball bearings 38 are coaxially sleeved on both ends of the stepped shaft 40. The upper adapter circular plate 37 is fixedly connected to the bottom of the mounting shell 14. The stepped shaft 40 passes through the adapter circular plate 37 and the end is coaxially fixedly connected to a mounting disc 41. The earth-breaking knife 24 is fixedly arranged on the mounting disc 41.

[0059] When the earth-breaking knife 24 is inserted downward into the soil, the stepped shaft 40 and the adapter plate 37 contact the ball bearing 38, so that the ball bearing 38 can rotate normally while making the thrust of the device pushing the earth-breaking knife 24 downward to dig the soil more stable, and avoiding damage to the device caused by the traditional connection method.

[0060] In order to show the structure of the medicine storage box 43, the following features are specifically provided:

[0061] There are two medicine storage boxes 43 and they are spaced apart above the earth-moving component 3 . A support platform 44 is fixedly provided below the two medicine storage boxes 43 . A medicine injection port 46 is provided above each medicine storage box 43 . A plurality of medicine spraying pipes 45 are evenly spaced apart on one side of each medicine storage box 43 .

[0062] When the device is in operation, the staff adds soil remediation agents into the medicine storage box 43 through the injection port 46. In the process of the excavating component 3 turning over the soil and breaking up large soil lumps, the soil remediation drugs are sprayed into the soil through the spray pipe 45, so that the drugs can be fully combined with the turned over and broken soil to complete the soil remediation work.

[0063] A method for treating contaminated soil comprises the following steps:

[0064] S1: The staff adds soil remediation drugs to the drug storage box 43;

[0065] S2: Start the tractor 1 to drive the power transmitter 5 to rotate;

[0066] S3: The power transmitter 5 drives all the rotating shafts 8 to rotate, and all the rotating shafts 8 drive the transmission rods 16 to rotate, thereby driving all the swingers 13, so that all the earth-breaking components 12 move alternately;

[0067] S4: All the rotating crushing mechanisms 23 are started, the rotating transmission device 26 drives the earth-breaking blade 24 to rotate, and the oscillator 13 drives the earth-breaking blade 24 to swing and dig the soil, and the two cooperate to make all the earth-breaking blades 24 dig the soil alternately and rotate to break up the soil blocks;

[0068] S5: The soil remediation drug is sprayed onto the turned soil through the drug storage box 43 to complete the soil remediation work.

[0069] Working principle: the staff first puts the required soil treatment drugs into the drug storage box 43, then starts the tractor 1, and adjusts the height of the entire digging component 3 from the ground through the lifter 2. After the adjustment is appropriate, the tractor 1 moves the entire digging component 3 forward. At this time, the power transmitter 5 transmits power to the rotating shaft 8, and all the rotating shafts 8 are driven to rotate. Each rotating shaft 8 drives two transmission rods 16 to rotate, and all the transmission rods 16 drive the oscillators 13 connected thereto to move. All the oscillators 13 are driven by the rotating shaft 8 to form a crank-like rotation, so that all the mounting shells 14 swing alternately around the hinge with the transmission rod 16, and the transmission rod 16 drives the mounting shell 14 to swing. Under the limit of the swing plate 19 on the mounting shell 14, the swing of the mounting shell 14 drives the swing plate 19 to swing back and forth, and the swing plate 19 drives the U-shaped bracket 21 to swing back and forth around the first connecting shaft 18 through the second connecting shaft 22 on the U-shaped bracket 21.

[0070] The wire rope 31 is in a tensioned state at all times under the action of the winding wheel 30. When the earth-breaking knife 24 is inserted into the soil, the wire rope 31 is in a tensioned state, and the winding wheel 30 is driven away from the rope frame 32. At this time, the winding wheel 30 is driven to release the wire rope 31, thereby driving the rolling shaft 25 to rotate and tighten the spring leaf 29, causing the earth-breaking knife 24 connected below to rotate. When the earth-breaking knife 24 is pulled out of the soil, the winding wheel 30 is driven close to the rope frame 32, and the wire rope 31 is relaxed at this time. However, as the spring leaf 29 is reset and drives the rolling shaft 25 to rotate in the opposite direction, the rolling shaft 25 drives the winding wheel 30 to rotate in the opposite direction, thereby tightening the relaxed wire rope 31 again, and the reverse rotation of the rolling shaft 25 also causes The soil-breaking knife 24 connected to the lower part rotates in the opposite direction. When the oscillator 13 is driven to rotate from the middle position to the lowest point from the ground, the soil-breaking knife 24 is driven to rotate and insert into the soil through the rotary transmission device 26. As the tractor 1 continues to move forward, the soil-breaking knife 24 is continuously driven to insert into the soil in a forward rotation manner and to be pulled out of the soil in a reverse rotation manner. The rotation of the soil-breaking knife 24 breaks up the large soil lumps brought out when being pulled out, so that the turning depth is deep enough and the large soil lumps turned out are broken at the same time, which greatly improves the work efficiency. When digging, the treatment medicine is applied to the treated soil through the medicine storage box 43, and the large lumps in the soil are removed, so that the medicine and the soil are fully combined, and the effect of soil treatment is also greatly improved.

[0071] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
