Description

Technical Field

[0001] The invention relates to the technical field of saline-alkali land restoration, and in particular to soil restoration equipment based on saline-alkali land improvement. Background Art

[0002] The improvement of saline-alkali land has always been regarded as a global problem. Not only in China, but also around the world, the existence of saline-alkali land has greatly restricted agricultural production and the effective use of land resources. The formation of saline-alkali land is mainly due to the excessive content of salt and alkaline substances in the soil, which leads to a decrease in soil fertility, limited crop growth, or even no growth. Therefore, developing effective saline-alkali land improvement technology and improving the utilization rate of saline-alkali land are of great significance to ensuring food security and promoting sustainable agricultural development.

[0003] The patent document with announcement number CN117397410B discloses a saline-alkali land repair device, which shovels the soil of the saline-alkali land onto the screen through a tipping bucket, and rolls and crushes the soil on the screen through a first roller. After being crushed into a standard size, the soil falls out through the screen holes, and the small soil blocks slide out through the discharge port on the right side of the connecting frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with a crushing mechanism, a punching mechanism and a material injection mechanism. The cone head first penetrates the soil layer, providing a precise path and direction for subsequent crushing and punching operations. The punching tube uses its smooth surface to reduce the damage to the soil structure, while ensuring the regularity of the hole formation, creating favorable conditions for the subsequent injection of the treatment agent. After reaching the preset depth, the crushing tube and the crushing structure thereon are synchronously rotated through the activation of the first driving structure to achieve efficient and uniform crushing of the surrounding soil. In this process, the temporary rise and fall of the punching tube not only protect the crushing structure from damage, but also ensure the smooth progress of the crushing operation and the punching operation without interfering with each other. After the crushing process is completed, the punching tube covers the crushing structure and rises synchronously to make room for the operation of the guide pipe. The treatment agent in the storage box is accurately injected into the crushed soil through the guide pipe, diffuses toward the surroundings, and effectively isolates the sunlight to prevent the rapid loss of the agent, thereby extending the effective action time of the treatment agent in the soil and improving the efficiency and effect of saline-alkali land improvement.

[0018] 2. The present invention is provided with a pressurizing structure, and the two fifth driving structures are started and work together at the same time, which ensures the uniformity and consistency of pressurization on both sides, makes the diffusion of the treatment agent more uniform, avoids the situation of local concentration being too high or too low, and improves the treatment effect. The pressurizing block realizes direct pressurization of the treatment agent through the reciprocating movement of the third lifting plate and the connecting rod, significantly improves the speed at which the agent is discharged from the liquid outlet, thereby accelerating the diffusion speed of the agent in the soil.

[0019] 3. The present invention is provided with a connecting ring and a crushing arm.

DETAILED DESCRIPTION

[0035] 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.

[0036] Reference Figures 1 to 14 As shown: a soil remediation device based on saline-alkali land improvement, including a walking structure 1, a crushing mechanism 2, a punching mechanism 3 and a material injection mechanism 4; the walking structure 1 includes a walking platform 11, the walking platform 11 is connected to the traction device, and the four corners of the walking platform 11 are provided with walking wheels 12; the crushing mechanism 2 is arranged in the middle of the walking platform 11, and the crushing mechanism 2 includes a first hanging plate 21, a crushing pipe 22 and a first driving structure 24, the first hanging plate 21 is arranged parallel to the top of the walking platform 11, and the crushing pipe 22 is arranged on the bottom of the walking platform 11. The crushing tube 22 has a plurality of sprockets 241 and chains 242, and the plurality of sprockets 241 are respectively connected to the plurality of first hoisting plates 21 and the plurality of first hoisting plates 21 are connected to the plurality of first hoisting plates 21. The crushing tube 22 has a plurality of sprockets 241 and chains 242, and the plurality of sprockets 241 are respectively connected to the plurality of first hoisting plates 21 and the plurality of first hoisting plates 21 are connected to the plurality of first hoisting plates 21. The chain 242 connects the plurality of sprockets 241; the punching mechanism 3 includes a second hanging plate 31 and a punching tube 32, the second hanging plate 31 is arranged in parallel below the corresponding first hanging plate 21, and the punching tube 32 has a plurality of holes, which are hung on the second hanging plate 31 at equal intervals, and the punching tube 32 is sleeved on the outside of the crushing tube 22. The second hanging plate 31 has at least two, and the two second hanging plates 31 correspond to the two first hanging plates 21 respectively. The punching tube 32 on the second hanging plate 31 They respectively correspond to the crushing tube 22 on the first lifting plate 21; the injection mechanism 4 includes a storage box 41 and a guide tube 42, the storage box 41 is arranged above the walking platform 11, and there are several guide tubes 42. One end of the guide tube 42 is connected to the storage box 41, and the other end of the guide tube 42 penetrates the crushing tube 22 downward, and a liquid outlet 421 is provided on the guide tube 42. The injection mechanism 4 also includes a cone head 43, which is connected to the lower end of the guide tube 42, and the maximum diameter of the cone head 43 is greater than the outer diameter of the perforated tube 32.

[0037] During the preparation stage, the soil remediation equipment is first firmly connected to the traction equipment through the walking platform 11 to ensure that the soil remediation equipment can be moved by external power. When the soil remediation equipment is started, each component is in the initial position, that is, the lower ends of the crushing tube 22, the perforating tube 32 and the guide tube 42 are aligned and lightly contact the cone head 43, forming a compact working starting point. When the soil remediation equipment is towed to the saline-alkali land to be improved, the crushing tube 22, the perforating tube 32 and the guide tube 42 move toward the ground at the same time, and the cone head 43 penetrates the soil layer first to open up a path for subsequent operations. As it goes deeper, the perforating tube 32 follows closely behind, using its smooth surface to form regular holes in the soil, reducing additional damage to the soil structure. Once the preset depth is reached, the perforating tube 32 temporarily rises to expose the crushing tube 22 below and the crushing tube 22 on it. Structure 23, at this time, the first driving structure 24 is activated, and through the precise sprocket 241 chain 242 transmission system, all the crushing tubes 22 are synchronously driven to rotate, and the crushing structure 23 thereon efficiently and evenly crushes the surrounding soil, creating favorable conditions for soil improvement, and then the perforated tube 32 descends again to cover the crushing structure 23, and the two rise synchronously to make room for the next operation of the guide tube 42, and the treatment agent in the storage box 41 is accurately injected into the crushed soil through the guide tube 42, and the treatment agent diffuses in all directions, and finally, the guide tube 42 is slowly withdrawn to allow the treatment agent to be fully mixed with the soil, effectively isolating the treatment agent from sunlight, preventing the rapid loss of the treatment agent, thereby extending the effective action time of the treatment agent in the soil and improving the efficiency and effect of saline-alkali land improvement.

[0038] Reference Figure 3 , Figure 4 and Figure 6 As shown: the injection mechanism 4 also includes a pressurizing structure 45, which includes a third hanging plate 451, a connecting rod 452, a second connecting plate 454 and a fifth driving structure 455; the third hanging plate 451 is arranged inside the storage box 41; there are several connecting rods 452, one end of which extends into the interior of the guide tube 42, and a pressurizing block 453 is arranged at one end of the connecting rod 452, and the other end of the connecting rod 452 is connected to the third hanging plate 451; there are two second connecting plates 454, and the two second connecting plates 454 are respectively arranged at both ends of the third hanging plate 451 and connected to the third hanging plate 451; there are two fifth driving structures 455, and the two fifth driving structures 455 respectively drive the two third hanging plates 451 to reciprocate along the axial direction of the connecting rod 452.

[0039] The treatment agent diffuses toward the surrounding soil by relying on its own fluidity. The soil hinders the flow of the treatment agent, resulting in a slower diffusion of the treatment agent and a smaller diffusion range. By setting the pressurizing structure 45, when the liquid outlet 421 of the guide tube 42 is exposed, the two fifth driving structures 455 are started at the same time and act on the two third hanging plates 451 respectively. The two third hanging plates 451 reciprocate along the axial direction of the connecting rod 452. As the third hanging plates 451 move horizontally, the connecting rod 452 closely connected thereto also moves. Since one end of the connecting rod 452 penetrates into the interior of the guide tube 42 and is equipped with a pressure block 453, the linear motion of the connecting rod 452 is directly converted into the downward thrust of the pressure block 453 in the guide tube 42. The pressure block 453 gradually approaches the bottom of the guide tube 42, exerting pressure on the treatment agent stored thereunder. As the pressure increases, the pressure of the treatment agent at the liquid outlet 421 also rises, causing the speed at which the agent is discharged from the liquid outlet 421 to be significantly accelerated, thereby accelerating the diffusion speed of the agent and increasing the diffusion range of the agent.

[0040] Reference Figure 3 , Figure 4 and Figure 6 As shown, the diameter of the pressure block 453 is the same as the inner diameter of the material guide tube 42 , a plurality of guide grooves 4531 are provided on the side wall of the pressure block 453 , and the guide grooves 4531 and the liquid outlet holes 421 on the material guide tube 42 are staggered with each other.

[0041] After the pressure block 453 squeezes out the treatment agent below it, it is necessary to add agents to the bottom of the pressure block 453. At the same time, it is necessary to prevent the treatment agent from flowing out of the liquid outlet 421 during the non-discharge stage of the guide tube 42. Therefore, the diameter of the pressure block 453 is designed to be the same as the inner diameter of the guide tube 42 to ensure a close fit between the two. In the initial state, the pressure block 453 is located at the lower end of the guide tube 42. Since the side wall of the pressure block 453 abuts against the inner wall of the guide tube 42, the side wall of the pressure block 453 completely blocks the liquid outlet 421 on the guide tube 42 to form a sealed environment. The guide groove 4531 opened on the side wall of the pressure block 453 is staggered from the liquid outlet 421, so that the treatment agent can The treatment agent can be filled in the guide groove 4531 without flowing out directly. When the treatment agent needs to be discharged, the connecting rod 452 pulls the pressure block 453 upward under the drive of the fifth driving structure 455. As the pressure block 453 rises, the liquid outlet 421 originally blocked by it gradually opens, and the treatment agent flows along the guide groove 4531 to the bottom of the pressure block 453. The space below the pressure block 453 is filled with the newly flowed treatment agent, preparing for subsequent pressurized discharge. Subsequently, the connecting rod 452 pushes the pressure block 453 downward again, exerting pressure on the treatment agent below, and the treatment agent is quickly discharged from the liquid outlet 421. The above process is repeated, thereby achieving continuous pressurization and efficient discharge of the treatment agent.

[0042] Reference Figure 6 , Figure 7 and Figure 8 As shown: the fifth driving structure 455 includes a swing arm 4551, and the two ends of the swing arm 4551 are respectively provided with a rotating shaft 4552 and a driving rod 4553, one end of the rotating shaft 4552 is connected to the swing arm 4551, and the other end of the rotating shaft 4552 extends to the outside of the storage box 41, one end of the driving rod 4553 is connected to the swing arm 4551, and the second connecting plate 454 is provided with a strip slide groove 4541 for accommodating the other end of the driving rod 4553.

[0043] When it is necessary to squeeze out the treatment agent in the guide tube 42, the fifth driving structure 455 is started, the rotating shaft 4552 begins to rotate around its own axis, and the swing arm 4551 rotates accordingly, thereby causing the driving rod 4553 to rotate around the axis of the rotating shaft 4552. As the driving rod 4553 rotates, it will reciprocate along the strip slide groove 4541, continuously applying upward and downward force to the strip slide groove 4541, and the force is finally transmitted to the pressure block 453 through the second connecting plate 454, the third lifting plate 451 and the connecting rod 452, driving the pressure block 453 to move up and down in the guide tube 42, thereby realizing the squeezing and discharge of the treatment agent.

[0044] Reference Figure 6 , Figure 7 and Figure 8 As shown: the pressurizing structure 45 also includes two second guide structures 456, the two second guide structures 456 correspond to the two second connecting plates 454 respectively, the second guide structure 456 includes a second guide column 4561 and a second guide sleeve 4562, the axis of the second guide column 4561 is parallel to the axis of the guide tube 42, and one end of the guide tube 42 is connected to the bottom of the storage box 41, the second guide sleeve 4562 is slidably set on the second guide column 4561, and the second guide sleeve 4562 is connected to the second connecting plate 454.

[0045] When the fifth driving structure 455 drives the third hanging plate 451 to rise and fall through the second connecting plate 454, the third hanging plate 451 may deviate from the vertical translation due to external factors, thereby causing the connecting rod 452 connected thereto to tilt and bend. By setting the second guide structure 456, the third hanging plate 451 will simultaneously drive the second guide sleeve 4562 to move when it is lifted and lowered. At this time, relative sliding occurs between the second guide sleeve 4562 and the second guide column 4561, and the sliding is strictly limited to the direction along the axis of the second guide column 4561. Therefore, no matter what direction of force the third hanging plate 451 is subjected to, the second guide structure 456 can ensure that the third hanging plate 451 can only be lifted and lowered reciprocatingly along the axis of the guide tube 42, thereby ensuring that the axis of the connecting rod 452 connected to the third hanging plate 451 is always in line with the axis of the guide tube 42, thereby avoiding tilting and bending of the connecting rod 452.

[0046] Reference Figure 5 and Fig. 9 As shown: the injection mechanism 4 also includes two third lifting structures 44, which are respectively arranged on both sides of the storage box 41, and the two third lifting structures 44 keep synchronous operation, and the third lifting structure 44 includes a second frame 441 and a fourth driving structure 442; the second frame 441 is installed on the walking platform 11, and the second frame 441 is used to increase the initial height of the fourth driving structure 442; the fourth driving structure 442 is arranged at the upper end of the second frame 441, and the fourth driving structure 442 includes a third U-shaped plate 4421, two third screw rods 4422, two A third moving block 4423 and two third driving plates 4424, the third U-shaped plate 4421 is fixed on the second frame 441, the two third screws 4422 are parallel to each other, the thread directions of the two third screws 4422 are opposite, the two ends of the third screw 4422 are respectively connected to the two ends of the third U-shaped plate 4421, the two third moving blocks 4423 are respectively connected to the two third screws 4422, the two third driving plates 4424 correspond to the two third moving blocks 4423, and the two ends of the third driving plate 4424 are respectively connected to the third moving block 4423 and the storage box 41 axis.

[0047] The two third lifting structures 44 keep running synchronously to keep the force balance of the storage box 41. One third lifting structure 44 has two third screws 4422 with opposite thread directions. The two third screws 4422 are arranged in parallel and penetrate the two ends of the third U-shaped plate 4421 with opposite thread directions, forming a precise transmission mechanism. When the two third screws 4422 rotate, the two third moving blocks 4423 move in opposite directions to achieve synchronous but opposite displacement. The two third moving blocks 4423 are respectively located at the two ends of the two third screws 4422. The movable plate 4424 is arranged in a cross form. When the lifting operation is started, the two third screws 4422 rotate synchronously. Due to the difference in thread direction, the two third moving blocks 4423 will move toward or away from each other. If the third screws 4422 rotate in the same direction, the third moving blocks 4423 move toward each other, driving the two ends of the third drive plate 4424 to gradually move closer, and the storage box 41 rises smoothly. On the contrary, if the rotation directions are opposite, the third moving blocks 4423 move away from each other, the two ends of the third drive plate 4424 separate, and the storage box 41 slowly descends, thereby achieving precise control of the height of the storage box 41.

[0048] Reference Figure 4 , Fig.10 and Fig.11 As shown: the crushing structure 23 includes a connecting ring 231 and a crushing arm 232; the connecting ring 231 is sleeved on the outside of the crushing tube 22; there are a plurality of crushing arms 232, and the plurality of crushing arms 232 are arranged in a circular array around the connecting ring 231, one end of the crushing arm 232 is hinged to the connecting ring 231, and a crushing hammer 2321 is arranged on the side wall of the crushing arm 232.

[0049] If the size of the crushing structure 23 is large, although the crushing structure 23 can crush the soil in a larger range, it needs a larger perforated tube 32 to cover it. The larger the size of the perforated tube 32, the more difficult it is to insert it into the soil. By providing a connecting ring 231 and a plurality of crushing arms 232, when the crushing structure 23 is placed vertically, the crushing arms 232 can naturally fit on the surface of the crushing tube 22, significantly reducing the overall size, allowing the use of a smaller perforated tube 32 to easily wrap it and insert it into the soil. The crushing structure 23 starts to work, and the crushing tube 22 rotates under power drive, and the rotational action is immediately transmitted to the connecting ring 231 connected thereto, thereby driving all the crushing arms 232 to rotate together. As the rotation speed increases, the crushing hammers 2321 on the crushing arms 232 begin to collide with the surrounding soil, gradually disintegrating the soil structure, and under the action of centrifugal force, the crushing arms 232 gradually spread outward to form a larger crushing range, effectively improving the crushing efficiency, thereby using a smaller crushing structure 23 to crush the soil in a larger range.

[0050] Reference Fig.10 , Fig.12 and Fig.13 As shown: the crushing mechanism 2 also includes two first lifting structures 25, which are respectively arranged at the two ends of the first hanging plate 21, and the first lifting structure 25 includes a first connecting plate 251, a first frame 252 and a second driving structure 253; the first connecting plate 251 is connected to the end of the first hanging plate 21; the first frame 252 is installed on the walking platform 11, and the first frame 252 is used to raise the initial height of the second driving structure 253; the second driving structure 253 is arranged at the upper end of the first frame 252, and the second driving structure 253 includes a first U-shaped plate 2531, two first screw rods 2 532, two first moving blocks 2533 and two first driving plates 2534, the first U-shaped plate 2531 is fixed on the first frame 252, the two first screw rods 2532 are parallel to each other, the thread directions of the two first screw rods 2532 are opposite, the two ends of the first screw rod 2532 are respectively connected to the two ends of the first U-shaped plate 2531, the two first moving blocks 2533 are respectively connected to the two first screw rods 2532, the two first driving plates 2534 correspond to the two first moving blocks 2533, and the two ends of the first driving plate 2534 are respectively axially connected to the first moving block 2533 and the end of the first hanging plate 21.

[0051] The cone head 43 drills into the soil only by the downward force transmitted by the guide tube 42, and the soil resistance is large, so the guide tube 42 needs to have greater rigidity to avoid bending. By setting two first lifting structures 25, the two first lifting structures 25 work at the same time, and one first lifting structure 25 has two first screws 2532 with opposite thread directions. The two first screws 2532 are arranged in parallel and penetrate the two ends of the first U-shaped plate 2531 with opposite thread directions, forming a precise transmission mechanism. When the two first screws 2532 rotate, the two first moving blocks 2533 move in opposite directions to achieve synchronous but opposite displacement. The two first moving blocks 2533 are respectively located at the two ends of the two first screws 2532. The two first drive plates 2534 are arranged in a cross form. When the lifting operation is started, the two first screws 2532 rotate synchronously. Due to the difference in the direction of the threads, the two first moving blocks 2533 will move toward or away from each other. If the first screws 2532 rotate in the same direction, the first moving blocks 2533 move toward each other, driving the two ends of the first drive plates 2534 to gradually approach each other, and the first hanging plate 21 rises smoothly. On the contrary, if the rotation directions are opposite, the first moving blocks 2533 move away from each other, the two ends of the first drive plates 2534 separate, and the first hanging plate 21 slowly descends. The first hanging plate 21 applies a downward force to the crushing tube 22 and transmits it to the cone head 43, so that the cone head 43 is subjected to additional force, thereby reducing the force of the guide tube 42 on the cone head 43.

[0052] Reference Fig.12 and Fig.13 As shown: the first lifting structure 25 also includes a first guide structure 254, which is arranged on the first connecting plate 251. The first guide structure 254 includes a first guide column 2541 and a first guide sleeve 2542. The first guide column 2541 is connected to the first connecting plate 251, and the axis of the first guide column 2541 is parallel to the axis of the crushing tube 22. The first guide sleeve 2542 is slidably connected to the first guide column 2541, and the first guide column 2541 is connected to the first frame 252.

[0053] When the first lifting plate 21 is lifted up and down by the force of the first lifting structure 25, if the first lifting plate 21 is deflected due to the outer wall, the first lifting plate 21 will drive the crushing tube 22 to deflect, and the crushing tube 22 will squeeze the perforated tube 32 and the guide tube 42 at the same time. By setting the first guide structure 254, when the second driving structure 253 starts to work, the second driving structure 253 drives the first connecting plate 251 and the first guide column 2541 connected thereto to perform lifting and lowering movements. Under the precise constraint of the first guide sleeve 2542, the first guide column 2541 moves linearly along its own axis, effectively preventing any deflection or shaking from the axis, and ensuring that the first lifting plate 21 can strictly move along the axial direction of the crushing tube 22 during the lifting process, thereby avoiding the deflection problem of the crushing tube 22 caused by external force or unstable factors.

[0054] Reference Figure 3 and Fig.14 As shown: the punching mechanism 3 also includes a second lifting structure 33, the second lifting structure 33 includes two third driving structures 331, the two third driving structures 331 are respectively arranged on both sides of the first hanging plate 21, and the two third driving structures 331 have opposite operating directions, the third driving structure 331 includes a second U-shaped plate 3311, a second screw rod 3312, a second moving block 3313 and a second driving plate 3314, the second U-shaped plate 3311 is connected to the first hanging plate 21, the two ends of the second screw rod 3312 are connected to the two ends of the second U-shaped plate 3311, the second moving block 3313 is arranged on the second screw rod 3312, and the two ends of the second driving plate 3314 are respectively axially connected to the second moving block 3313 and the second hanging plate 31.

[0055] The second lifting plate 31 is precisely lifted and lowered by two third drive structures 331 arranged opposite to each other. The two third drive structures 331 are respectively fixed on both sides of the first lifting plate 21, and the running directions of the two third drive structures 331 are set to be opposite to each other, so as to ensure that the forces applied to the second lifting plate 31 can be balanced with each other. When the second lifting structure 33 starts to work, the two third drive structures 331 are started at the same time. With the rotation of the second screw rod 3312, the second moving block 3313 starts to move along the thread of the screw rod. Since the running directions of the two third drive structures 331 are opposite to each other, the two second moving blocks 33 13 will move toward the end or middle of the second screw rod 3312 respectively, and the synchronous and opposite movement will be converted into the lifting drive of the second hanging plate 31 through the second driving plate 3314. When the second screw rod 3312 rotates forward, the second moving block 3313 moves toward the end of the second screw rod 3312, pushing the second hanging plate 31 toward the first hanging plate 21. Conversely, when the second screw rod 3312 rotates reversely, the second moving block 3313 moves toward the middle of the second screw rod 3312, pulling the second hanging plate 31 away from the first hanging plate 21, thereby realizing precise control of the position of the second hanging plate 31.
