Description

Technical Field

[0001] This invention relates to the field of soil improvement and remediation technology, specifically to an ecological soil targeted improvement and remediation device. Background Technology

[0002] Soil improvement and remediation refers to the treatment of soil through physical, chemical, and biological methods to improve its physical and chemical properties, biological activity, and ecological environment, thereby improving soil quality, reducing pollutant content, and enhancing its ecological functions. There are various soil improvement and remediation technologies, which can be selected based on the specific soil problems and remediation goals. Currently, soil improvement and remediation typically involves first tilling the soil with a deep tillage machine, and then spraying a remediation agent on the soil (the remediation agent can be selected based on the specific soil problems).

[0003] Currently, when using existing deep tillage machines, the soil that is tilled is mostly in clumps. This makes it difficult for the soil repair agent to penetrate into the clumps in a short time, resulting in poor soil repair effect. Moreover, when planting on the soil that has been sprayed with the repair agent, it is necessary to break up the tilled clumps separately, which not only increases the operation process but also increases various costs. Summary of the Invention

[0004] The purpose of this invention is to provide an ecological soil targeted improvement and remediation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An ecological soil targeted improvement and remediation device includes a deep tillage machine body, a connecting frame rotatably connected to the rear end of the deep tillage machine body, a shovel mechanism for shoveling and breaking up tilled soil clods inside the connecting frame, a connecting mechanism for driving the shovel mechanism to make circular motion on the side of the connecting frame, a pushing mechanism for moving the shovel mechanism on both sides of the connecting frame, and a spraying mechanism for spraying remediation agent onto the broken soil after tillage at one top end of the connecting frame.

[0007] The connecting frame has sliding holes through both sides, and a support rod slides through between the two sliding holes. The outer walls of the support rod are fixedly connected to the fixing frames at both ends.

[0008] The soil-shoveling mechanism includes multiple rollers arranged in a ring at equal angles and fixedly connected between two fixed frames. The outer wall of each roller has a notch, and a shovel plate is fixedly connected to the outer wall of the roller at the corresponding notch. Both ends of each roller are fixedly connected to cylindrical sleeves that penetrate and are fixed to the fixed frames at the corresponding positions. A round rod is rotatably connected between the two ends inside the roller, and several rotary tillage blades are fixedly connected to the outer wall of the round rod.

[0009] Furthermore, one end of the round rod passes through the roller and cylindrical sleeve at the corresponding position and is fixedly connected to a second sprocket. Both ends of the outer wall of the support rod are rotatably connected to fixed sleeves that slide through the corresponding sliding holes. The outer wall of the fixed sleeve is fixedly connected to two third sprockets. The third sprockets and the second sprocket at the corresponding position are connected by a chain drive.

[0010] Furthermore, both ends of the outer wall of the tillage shovel drive shaft of the deep tillage machine body are fixedly connected to a sprocket, and the outer wall of the fixed sleeve is fixedly connected to a sprocket four that is connected to the sprocket one at the corresponding position through a chain two.

[0011] Furthermore, the outer wall of the fixed sleeve is fixedly connected with a limiting ring that abuts against the connecting frame, and tensioning mechanisms are fixedly connected to both sides of the deep turning machine body.

[0012] Furthermore, the pushing mechanism includes two symmetrical turntables, which are rotatably connected to a connecting shaft at their relative positions and off-center. A connecting plate is fixedly connected to the outer wall of the connecting shaft, and a sliding sleeve is slidably sleeved on the outer side of the connecting plate. One end of the sliding sleeve is fixedly connected to a connecting block that rotates through the support rod.

[0013] Furthermore, both the connecting plate and the corresponding sliding sleeve have through holes on their sides.

[0014] Furthermore, one end of the outer wall of the support rod is fixedly connected to a bevel gear, and one of the turntables near the outer side is fixedly connected to an electromagnetic clutch via a rotating rod. One side of the electromagnetic clutch is fixedly connected to a bevel gear via a rotating rod. The connecting mechanism includes two rotating shafts, the outer walls of which are fixedly connected to bevel gears. The two bevel gears mesh with bevel gears one and three respectively, and a connecting piece is provided between the two bevel gears.

[0015] Furthermore, the connecting component includes a universal joint, one end of which is fixedly connected to a rotating shaft at a corresponding position, and the other end of which is fixedly connected to a rectangular sleeve. Inside the rectangular sleeve, a square column fixedly connected to the rotating shaft at a corresponding position is slidably fitted. Both rotating shafts are fixedly connected to the sides of the connecting frame and the deep turning machine body respectively through stabilizing plates.

[0016] Furthermore, the rear end of the deep turning machine body is fixedly connected to two symmetrical rotating seats that are rotatably connected to the connecting frame. A connecting rod that rotatably passes through the two rotating seats and passes through the connecting frame. Worm gears are fixedly connected to both ends of the outer wall of the connecting rod. A worm gear that meshes with the worm gear at the corresponding position is rotatably connected to the side of the deep turning machine body through a support block. An electromagnetic clutch is fixedly connected to one end of the worm gear.

[0017] Furthermore, the connecting frame is provided with two universal support rollers at the end away from the deep turning machine body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Through the circular motion of multiple roller seats, and the cooperation of the pushing mechanism and the connecting mechanism, soil clods above the shovel plate can be shoveled into the rollers and broken up, so that the repair agent sprayed by the spraying mechanism can be better absorbed by the soil. Moreover, during later planting, there is no need to break up the soil clods, which can save later operations and reduce various costs.

[0020] 2. The rotation of the turntable can cause the two connecting plates to move back and forth, thus allowing the support rod to move back and forth between the two sliding holes along the length of the sliding holes. This allows the bottom roller to be moved behind the soil clods, so that multiple rollers can scoop as many soil clods as possible from above the shovel plate into their respective rollers for crushing. This can minimize the presence of large soil clods on the ground in the opposite direction of the deep turning machine's movement.

[0021] 3. By switching the electromagnetic clutch on and off, multiple rollers can be controlled to move intermittently in a circular motion, so that the shovel can shovel a certain amount of soil into the rollers for crushing, and also allow enough time for the soil in the rollers with the notch facing downwards to fall out.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 - Figure 9 In this embodiment of the invention, an ecological soil targeted improvement and remediation device includes a deep tillage machine body 1. A connecting frame 2 is rotatably connected to the rear end of the deep tillage machine body 1. A shovel mechanism 3 is installed inside the connecting frame 2 to shovel and break up the tilled soil protrusions. A connecting mechanism 4 is provided on the side of the connecting plate 522 of the connecting frame to drive the shovel mechanism 3 in a circular motion. Pushing mechanisms 5 are provided on both sides of the connecting plate 522 to move the shovel mechanism 3. A spraying mechanism 6 is provided at the top end of the connecting plate 522 to spray a remediation agent onto the broken tilled soil. Both sides are provided with sliding holes 21, and a support rod slides through between the two sliding holes 21. The outer walls of the support rod are fixedly connected to the two ends of the fixed frame 22. The soil-moving mechanism 3 includes multiple rollers 31 distributed in a ring at equal angles and fixedly connected between the two fixed frames 22. The outer wall of the roller 31 is provided with a notch, and a shovel plate 32 is fixedly connected to the outer wall of the roller 31 at the corresponding notch. Both ends of the roller 31 are fixedly connected with cylindrical sleeves 33 that pass through and are fixed to the fixed frames 22 at the corresponding positions. The inner ends of the roller 31 are rotatably connected to a round rod 34, and several rotary tillage blades 35 are fixedly connected to the outer wall of the round rod 34.

[0034] Specifically, first, the connecting frame 2 is lowered so that the bottom of the lowest roller 31 is flush with or lower than the bottom of the track of the deep tiller body 1. Then, driven by the deep tiller body 1, it can move while tilling the land. Since the tilling blades of the deep tiller body 1 break up the soil during tilling, and most of the broken soil is in clumps and protrudes from the soil surface, the deep tiller moves forward, driving multiple rollers 31 forward. The lowest roller 31, which moves forward, uses the shovel 32 to shovel soil clumps higher than the shovel 32 into the lowest roller 31. Then, the round rod 34 drives multiple rotary blades 35 to rotate, breaking up the protrusions inside the roller 31. Finally, the soil is tilled by the connecting frame 2. The connecting mechanism 4 drives the support rod to rotate, which moves the roller 31 containing soil clods upward, while the next roller 31 moves to the bottom. Since the deep tillage machine body 1 also moves forward as the roller 31 moves upward, some soil clods will not be shoveled into the next roller 31 when it reaches the bottom. At this point, the connecting mechanism 4 can be disengaged from the tillage shovel drive shaft of the deep tillage machine body 1. Then, the support rod is moved to the other end of the sliding hole 21 via the pushing mechanism 5, so that the bottom roller 31 is located behind the soil clods. Since the connecting mechanism 4 is disengaged from the tillage shovel drive shaft of the deep tillage machine body 1, multiple rollers 31 stop rotating, and then the deep tillage machine body 1... The movement, and by pushing the support rod back to its original position via the pushing mechanism 5, allows the bottom roller 31 to scoop up the soil clods. Then, the connecting mechanism 4 is connected to the tillage shovel drive shaft of the deep tillage machine body 1, causing multiple rollers 31 to rotate again. This reciprocating operation scoops the soil clods from the bottom shovel plate 32 into the roller 31 (since the tillage shovel of the deep tillage machine body 1 inserts relatively deep into the soil, and planting generally does not require very deep pits, the soil clods at the bottom of the trench do not need to be broken). The soil clods are then broken up by the rotary tillage blades 35 inside the roller 31. When the notch of the roller 31 begins to face downwards, the broken soil inside the roller 31 falls to the ground under its own gravity. At the same time, the remediation agent is sprayed by the spraying mechanism 6. Spraying the remediation agent onto the broken soil allows for better absorption of the soil. The device uses multiple rollers 31 in circular motion, and through the cooperation of the pushing mechanism 5 and the connecting mechanism 4, it can shovel soil clods above the shovel plate 32 into the rollers 31 and break them up, so that the remediation agent sprayed by the spraying mechanism 6 can be better absorbed by the soil. Moreover, during later planting, there is no need to break up the soil clods again, which can save on later operations and reduce various costs (such as equipment costs, labor costs, etc.). The deep tillage machine body 1 and the spraying mechanism 6 mentioned above are existing technologies and will not be described in detail here. Furthermore, the choice of remediation agent can be determined based on the soil test results in advance, so as to enable targeted soil remediation treatment.

[0035] Example 1

[0036] like Figure 4 - Figure 6 As shown, in this embodiment, one end of the round rod 34 passes through the roller 31 and cylindrical sleeve 33 at the corresponding position and is fixedly connected to a second sprocket 36. Both ends of the outer wall of the support rod are rotatably connected to a fixed sleeve 37 that slides through the corresponding sliding hole 21. The outer wall of the fixed sleeve 37 is fixedly connected to two third sprockets 38. The third sprocket 38 and the second sprocket 36 at the corresponding position are connected by a chain drive. Both ends of the outer wall of the tillage shovel drive shaft of the deep tillage machine body 1 are fixedly connected to a first sprocket 11. The outer wall of the fixed sleeve 37 is fixedly connected to a fourth sprocket 39 that is connected to the first sprocket 11 at the corresponding position by a chain drive. The outer wall of the fixed sleeve 37 is fixedly connected to a limiting ring that abuts against the connecting frame 2. Tensioning mechanisms 12 are fixedly connected to both sides of the deep tillage machine body 1.

[0037] In this embodiment, the rotation of the tillage shovel drive shaft of the deep tillage machine body 1 can cause the sprocket 11 to drive the sprocket 4 39 at the corresponding position to rotate, thereby causing the two sprockets 38 at the corresponding position to rotate. Therefore, the rotary tillage blades 35 inside the drum 31 can rotate to break up the soil clods in the drum 31. The tensioning mechanism 12 can keep the chain 2 at the corresponding position in a taut state. The tensioning mechanism 12 is existing technology and will not be described in detail here.

[0038] Example 2

[0039] like Figure 1 and Figure 8 As shown, in this embodiment, the pushing mechanism 5 includes two symmetrical turntables 51. The two turntables 51 at opposite positions and off-center are rotatably connected to a connecting shaft. A connecting plate 52 is fixedly connected to the outer wall of the connecting shaft. A sliding sleeve 53 is slidably sleeved on the outer side of the connecting plate 52. A connecting block that rotates through the support rod is fixedly connected to one end of the sliding sleeve 53. Through holes 54 are opened on the sides of the connecting plate 52 and the corresponding sliding sleeve 53.

[0040] In this embodiment, a pin is first inserted into the through hole 54. When one of the rollers 31 moves to the bottom, the drive shaft of the tillage shovel of the deep tillage machine body 1 can rotate the four turntables 51. Since the connecting plate 52 is limited to a position away from the center of the turntable 51, the rotation of the drive shaft of the tillage shovel of the deep tillage machine body 1 can cause the two connecting plates 52 to move back and forth. The movement of the connecting plate 52 can drive the sliding sleeve 53 to move through the pin. Therefore, the support rod can move back and forth between the two sliding holes 21 along the length of the sliding hole 21, thereby moving the bottom roller 31 to the back of the soil clods. This allows the multiple rollers 31 to shovel as much soil clods as possible above the shovel plate 32 into their respective rollers 31 for crushing, thus minimizing the presence of large soil clods on the ground in the opposite direction of the movement of the deep tillage machine body 1.

[0041] Example 3

[0042] like Figure 1 and Figures 7-9 As shown, in this embodiment, a bevel gear 23 is fixedly connected to one end of the outer wall of the support rod. An electromagnetic clutch 55 is fixedly connected to the side of one of the turntables 51 near the outer side via a rotating rod. A bevel gear 56 is fixedly connected to one side of the electromagnetic clutch 55 via a rotating rod. The connecting mechanism 4 includes two rotating shafts 41. A bevel gear 42 is fixedly connected to the outer wall of the rotating shaft 41. The two bevel gears 42 mesh with the bevel gear 23 and the bevel gear 56 respectively. A connecting member is provided between the two bevel gears 42. The connecting member includes a universal joint 43. One end of the universal joint 43 is fixedly connected to the rotating shaft 41 at the corresponding position. A rectangular sleeve 45 is fixedly connected to the other end of the universal joint 43. A square column 44, which is fixedly connected to the rotating shaft 41 at the corresponding position, is slidably sleeved inside the rectangular sleeve 45. The two rotating shafts 41 are fixedly connected to the side of the connecting frame 2 and the deep turning machine body 1 respectively via a stabilizing plate 24.

[0043] In this embodiment, by connecting the wire of the electromagnetic clutch 2 55 to the power system of the deep turning machine body 1, and by providing a switch to control the on / off state of the electromagnetic clutch 2 55, energizing the electromagnetic clutch 2 55 causes the rotating rod 1 to drive the rotating rod 2 and the bevel gear 3 56 to rotate. The rotating bevel gear 3 56 causes the bevel gear 2 42 at the corresponding position to drive the universal joint 43 to rotate and another bevel gear 2 42 to rotate. This causes the bevel gear 1 23 to drive the support rod to rotate. The rotation of the support rod causes multiple rollers 31 to perform circular motion, so that the bottom roller 31 can use the shovel plate 32 to scoop up the protrusion and break it. The soil is broken up, and then automatically dumped out as the support rod rotates. When the drum 31 moves to the bottom, the electromagnetic clutch 55 is de-energized. At this time, the rotation of the first rotating rod cannot drive the second rotating rod to rotate, so the support rod also stops rotating. After a certain amount of soil is shoveled into the drum 31, the electromagnetic clutch 55 is energized again, causing the first rotating rod to drive the second rotating rod to rotate. By controlling the on and off of the electromagnetic clutch 55, multiple drums 31 can be controlled to intermittently perform circular motion, so that the shovel 32 can shovel a certain amount of soil into the drum 31 for breaking, and also allow sufficient time for the soil in the downward-facing drum 31 to fall out. Figure 9 As shown, protective shells are installed at bevel gear 1 23, bevel gear 3 56 and two bevel gears 2 42. Two rotating shafts 41 slide through the corresponding stabilizing plates 24, and the two rotating shafts, support rods and rotating rods 2 rotate through the protective shells at the corresponding positions to prevent bevel gear 1 23, bevel gear 2 42 and bevel gear 3 56 from being directly exposed.

[0044] Example 4

[0045] like Figure 3 As shown, in this embodiment, the rear end of the deep turning machine body 1 is fixedly connected to two symmetrical rotating seats that are rotatably connected to the connecting frame 2. A connecting rod that rotatably passes through the connecting frame 2 is connected between the two rotating seats. Worm gears 25 are fixedly connected to both ends of the outer wall of the connecting rod. A worm 26 that meshes with the worm gear 25 at the corresponding position is connected through a support block on the side of the deep turning machine body 1. An electromagnetic clutch 27 is fixedly connected to one end of the worm 26. Two universal support rollers 28 are provided at the end of the connecting frame 2 away from the deep turning machine body 1.

[0046] In this embodiment, one side of the electromagnetic clutch 27 is first connected to the engine drive shaft of the deep tillage machine body 1 via a rotating rod, spur gear, bevel gear, etc. This connection method is existing technology and will not be described in detail here. When the land needs to be tilled, the land is first tilled by the deep tillage machine. Then, by energizing the two electromagnetic clutches 27 (the energizing and de-energizing method of the electromagnetic clutches 27 is the same as that of the electromagnetic clutches 55), the rotation of the engine drive shaft of the deep tillage machine body 1 can cause the two worm gears 26 to drive the two worm wheels 25 to rotate, and the connecting frame 2 can be lowered until the two universal supports are in place. The roller 28 is in contact with the ground, and at this time, the bottom shovel 32, the universal support roller 28, and the track of the deep tillage machine body 1 are on the same plane, which can shovel the soil above the ground into the drum 31. If it is necessary to shovel deeper soil into the drum 31, the support frame of the universal support roller 28 can be set to telescopic, and the length of the support frame can be limited by the pin. When the length of the support frame is shortened, the two universal support rollers 28 are in contact with the ground, and the bottom shovel 32 is located below the universal support roller 28, which can shovel deeper soil into the drum 31.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
