Description
Technical Field
[0001] This application relates to the field of soil remediation technology, and in particular to a soil remediation device and method for landscaping. Background Technology
[0002] After a period of time, the topsoil of a garden can easily lose its activity due to high-density planting of plants. The soil fertility decreases, the roots become tangled and knotted, and the soil becomes severely compacted. At this point, the soil can no longer support the growth of the plants, the roots of the dead plants rot in the soil, and the soil becomes unfavorable for plant growth.
[0003] However, it is difficult to remove roots and debris from the soil by manually turning over the soil. In response to this situation, soil remediation equipment has emerged. Soil remediation equipment can renovate the topsoil, remove messy roots, and enhance soil fertility, making the land in a certain area suitable for plant growth again. Summary of the Invention
[0004] In order to remove tangled roots from the soil during soil turning, this application provides a soil treatment device and method for landscaping.
[0005] The technical solution adopted in this application for a soil remediation device and method for landscaping is as follows:
[0006] A soil remediation device for landscaping includes a movable frame with an outer shell. Below the outer shell are soil-breaking structures that extend laterally below ground level. Each extended end of the soil-breaking structure has a forward-facing protrusion. Behind the soil-breaking structure is a rotatably connected circular drive structure, which drives the protrusions of the soil-breaking structure to rotate circumferentially along the vertical plane of the frame. Behind the circular drive structure is a rotatably connected conveyor structure, one end of which is connected to the ground level, and the other end to the top of the frame. The frame... The device is equipped with a soil screening structure, which includes a soil screening grid and a soil screening baffle. The soil screening grid is arranged horizontally at intervals. One end of the soil screening grid is close to the conveying structure, and the other end extends downward at an angle and is rotatably connected to the frame. The soil screening baffle is fixed to the rotating end of the soil screening grid and extends upward at an angle towards the rear of the frame. A hot roller is provided behind the soil screening baffle and is rotatably connected to the frame and abuts against it. A separation structure is slidably connected to the frame at the opening of the soil screening structure. The separation structure passes through the opening of the soil screening grid, abuts against the soil screening baffle, and slides towards the hot roller.
[0007] By adopting the above technical solution, the soil breaking structure breaks up the soil surface while advancing the pit, which facilitates the subsequent root separation. The broken soil is transported to the inside of the device by the conveying structure and then separated by the soil screening grid inside the device. The loose soil falls below through the gaps between the soil screening grids, which is convenient for subsequent processing and backfilling. Larger stones are intercepted by the soil screening grids, which is convenient for subsequent collection and processing. Since the roots are light and have strong toughness, they are difficult to pass through the soil screening grids. Therefore, the separation structure is used to pick up the roots and heat and crush them to complete the deactivation and sterilization process, thereby completing the root removal process.
[0008] Preferably, the soil screening structure also includes a soil box, a stone box, and a control handle. The soil box is fixed to the frame and located below the vertical projection of the soil screening grid. A stirring rod is rotatably connected inside the soil box at intervals, and the bottom opening of the soil box is connected to the ground. The stone box is fixed to the frame and located on the side of the soil box near the front of the frame. The control handle is rotatably connected to the soil screening baffle, and the upper end of the control handle can abut against the frame.
[0009] By adopting the above technical solution, the soil bin is connected to the ground. Fine soil can be returned to the ground through screening, while large stones will roll down into the stone bin with the soil screening grid, thereby increasing the looseness of the soil and making it more conducive to plant growth. The mixing roller can better fertilize the land by mixing the soil evenly with the fertilizer liquid.
[0010] Preferably, the extended feeding structure includes a receiving plate, abutting rods, a control arc rod, a drive rod, and a return spring. The receiving plate is laterally slidably connected to the frame and is positioned on the side of the chain belt near the screen grid. The abutting rods are fixed at intervals to the outside of the sprockets. The control arc rod is rotatably connected to the frame, and the end of the control arc rod near the abutting rod is arc-shaped, corresponding to the rotation trajectory of the outer edge of the abutting rod. The drive rod is fixed to the rotating end of the control arc rod and sleeved on both sides of one end of the receiving plate, and the control arc rod is shorter than the drive rod. One end of the return spring is fixed to the frame, and the other end is fixed to and drives the drive rod away from the chain belt.
[0011] By adopting the above technical solution, the receiving plate, in conjunction with the bucket, can better receive the soil in the bucket and prevent it from falling. The extension and retraction of the receiving plate can be synchronized with the bucket to prevent them from colliding. Furthermore, the receiving plate allows the bucket to be closer to the chain, thus occupying less space and providing more support from the chain.
[0012] According to the claim, a soil treatment device for landscaping is characterized in that: the separation structure includes a separation claw and a circulating belt, the circulating belt is rotatably connected to both sides of the frame and is inclined, the bottom end of the circulating belt is located above the rotating connection of the soil screening grid, and the top end of the circulating belt is located above the hot roller; the separation claw is rotatably connected to the two circulating belts and extends downward through the gaps between the soil screening grids, and the bottom end of the separation claw bends towards the rear of the frame, and the bent end can abut against the soil screening baffle.
[0013] According to the claim, a soil remediation device for landscaping is characterized in that: the soil breaking structure includes a soil breaking support and a soil breaking cone, the two ends of the soil breaking support are rotatably connected to a circumferential drive structure, the soil breaking support extends downward at intervals and penetrates the ground; the soil breaking cone is fixed at intervals to the front end of the soil breaking support, and the soil breaking cone gradually contracts inward from back to front on both sides.
[0014] Preferably, a fertilizer application structure is provided below the hot roller. The fertilizer application structure includes a liquid dispensing tank and a crushing blade. The liquid dispensing tank is fixed to the frame and is set below the hot roller. The top of the liquid dispensing tank is open and the bottom is connected to the soil box. The crushing blade is rotatably connected to the liquid dispensing tank and is set at the connection point of the soil box.
[0015] By adopting the above technical solution, the crushing blade is used to backfill the heat-treated root system, which enhances the soil support and reduces the subsequent treatment of the root system. The treated root system can be directly backfilled into the soil.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] 1. As the soil-breaking structure advances into the pit, it breaks up the soil surface, facilitating subsequent root separation. The broken soil is transported to the inside of the device by the conveying structure and then separated multiple times by the soil-screening grid inside the device. The loose soil falls through the gaps between the soil-screening grids to the bottom, facilitating subsequent processing and backfilling. Larger stones are intercepted by the soil-screening grids, facilitating subsequent collection and processing. However, because the roots are light and have strong toughness, they are difficult to pass through the soil-screening grids. Therefore, the separation structure is used to pick up the roots and heat and crush them to complete the deactivation and sterilization process, thus completing the root removal process.
[0018] 2. The soil bin is connected to the ground. Fine soil can be returned to the ground through screening, while large stones will roll down into the stone bin with the soil screening grid, thereby increasing the looseness of the soil and making it more conducive to plant growth. The mixing roller can better enrich the land by mixing the soil evenly with the fertilizer liquid.
[0019] 3. The receiving plate, in conjunction with the bucket, can better receive the soil in the bucket and prevent it from falling out. The extension and retraction of the receiving plate can be synchronized with the bucket to prevent them from colliding. The receiving plate also allows the bucket to be closer to the chain, thus taking up less space and providing more support from the chain.
[0020] 4. The crushing blade is used to backfill the heat-treated roots, which enhances the soil's support and reduces the need for subsequent root treatment. The treated roots can be directly backfilled into the soil. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] This application discloses a soil treatment device and method for landscaping, referring to... Figure 1 , 2The device includes a movable frame 1, with an outer shell on the frame 1 and a soil-breaking structure 2 under the outer shell. The soil-breaking structure 2 includes a soil-breaking support 21 and a soil-breaking cone 22. The soil-breaking support 21 extends downward at intervals and penetrates the ground. The soil-breaking cone 22 is fixed at intervals to the front end of the soil-breaking support 21. The plant roots have strong longitudinal toughness but weak lateral toughness. The soil-breaking cone 22 gradually contracts inward from the back to the front sides, thereby preventing the plant roots from being cut laterally by the soil-breaking cone 22. The soil-breaking support 21 is connected to the frame 1 through a circumferential drive structure 3.
[0029] Reference Figure 2 , 3 The circumferential drive structure 3 includes a flywheel 31, a rotating shaft 32, a synchronous belt 33, and a circumferential motor 34. The flywheel 31 is rotatably connected to the left and right sides of the front end of the frame 1, and the two flywheels 31 are coplanar. The rotating shaft 32 is rotatably connected to the same side of the outer ring of the corresponding flywheel 31, and the two rotating shafts 32 are rotatably connected to the two sides of the top of the soil breaking support 21. The synchronous belt 33 is sleeved on the two flywheels 31. The circumferential motor 34 is fixed to the frame 1, and the output shaft of the circumferential motor 34 is fixed to the flywheel 31.

The conveying structure 4 includes a sprocket 41, a chain belt 42 and a bucket 43. The sprocket 41 is longitudinally spaced and rotatably connected to the frame 1. The chain belt 42 extends longitudinally and is sleeved on the sprocket 41. The buckets 43 extend laterally and are fixed to the chain belt 42 at intervals. The opening of the bucket 43 is upward on the side near the soil breaking structure 2. An elastic extension plate 10 extends along the opening direction of the bucket 43 on the side near the chain belt 42. An extension feeding structure 8 is provided at the top of the chain belt 42. The elastic extension plate 10 cooperates with the extension feeding structure 8 to feed material backward.
[0031] Reference Figure 2 , 4 The extended feeding structure 8 includes a receiving plate 81, abutting rods 82, a control arc rod 83, a drive rod 84, and a return spring 85. The receiving plate 81 is laterally slidably connected to the frame 1 and is positioned on the side of the top of the chain belt 42 near the rear of the frame 1. The abutting rods 82 are fixed at intervals to the outside of the sprockets 41. The control arc rod 83 is rotatably connected to the frame 1, and the end of the control arc rod 83 near the abutting rod 82 is arc-shaped, corresponding to the outer edge of the abutting rod 82's rotation trajectory. The drive rod 84 is fixed to the rotating end of the control arc rod 83 and sleeved on both sides of one end of the receiving plate 81, with the control arc rod 83 being shorter than the drive rod 84. One end of the return spring 85 is fixed to the frame 1, and the other end is fixed to and drives the drive rod 84 away from the chain belt 42.
[0032] Reference Figure 2 , 4When the abutting rod 82 rotates with the sprocket 41 and abuts against the control arc rod 83, the control arc rod 83 rotates and drives the drive rod 84 to abut against the receiving plate 81 and approach the bucket 43 near the top of the chain belt 42, and is misaligned with the first bucket 43 on the side of the chain belt 42 near the rear of the frame 1. The soil in the bucket 43 enters the receiving plate 81 with the elastic extension plate 10. The abutting rod 82 rotates along the arc end of the control arc rod 83 to maintain the position of the receiving plate 81. When the elastic extension plate 10 passes through the receiving plate 81, the abutting rod 82 is misaligned with the control arc rod 83, and the return spring 85 drives the receiving plate 81 to slide backward and is misaligned with the bucket 43.
[0033] Reference Figure 2 , 5 An extension conveyor belt 11 is rotatably connected to the frame 1. One side of the extension conveyor belt 11 is located below the receiving plate 81, and the other side is equipped with a soil screening structure 6. The soil screening structure 6 includes a soil screening grid 61, a soil screening baffle 62, a soil box 63, a stone box 64, and a control handle 65. The soil screening grids 61 are arranged horizontally at intervals. One end of the soil screening grid 61 is close to the extension conveyor belt 11, and the other end extends downward at an angle and is rotatably connected to the frame 1. The soil screening baffle 62 is fixed to the rotating end of the soil screening grid 61 and extends upward toward the rear of the frame 1.
[0034] Reference Figure 2 , 5 The soil bin 63 is fixed to the frame 1 and located below the vertical projection of the soil screen 61. The soil bin 63 is rotatably connected with stirring rods 12 at intervals, and the bottom opening of the soil bin 63 is connected to the ground. The stone bin 64 is fixed to the frame 1 and located on the side of the soil bin 63 near the front of the frame 1, and the stone bin 64 is located below the extension conveyor belt 11. The control handle 65 is rotatably connected to the soil screen baffle 62, and the upper end of the control handle 65 can abut against the frame 1. When the control handle 65 rotates laterally and is misaligned with the frame 1, the soil screen 61 rotates downward and tilts, and the stones abutting against the soil screen 61 roll down to the stone bin 64 as the soil screen 61 tilts.
[0035] Reference Figure 2 , 5 The soil screening structure 6 is equipped with a separation structure 5 for separating plant roots and stems. The separation structure 5 includes a separation claw 51 and a circulating belt 52. The circulating belt 52 is rotatably connected to both sides of the frame 1 and is set at an inclination. The bottom end of the circulating belt 52 is located above the rotatable connection of the soil screening grid 61, and the top end of the circulating belt 52 is set behind the soil screening baffle 62. Below the circulating belt 52, there is a hot roller 7 that is rotatably connected to the frame 1 and abuts against each other. The separation claw 51 is rotatably connected to the two circulating belts 52 and extends downward through the gaps between the soil screening grid 61. The bottom end of the separation claw 51 is bent towards the rear of the frame 1, and the bent end can abut against the soil screening baffle 62.
[0036] A fertilizer application structure 9 is provided below the hot roller 7. The fertilizer application structure 9 includes a liquid mixing tank 91 and a crushing blade 92. The liquid mixing tank 91 is fixed to the frame 1 and is set below the hot roller 7. The top of the liquid mixing tank 91 is open and the bottom is connected to the soil box 63. The crushing blade 92 is rotatably connected to the liquid mixing tank 91 and is set at the connection point of the soil box 63.
[0037] The working process of this application is as follows: S1: A pit is pre-excavated on the ground to accommodate the soil breaking support 21 and the bucket 43. The flywheel 31 drives the soil breaking cone 22 to rotate in a circle. The soil breaking cone 22 moves forward with the support 1 to break up the soil and the roots in the soil. The soil material comes to the bucket 43 through the gap of the soil breaking support 21. The bucket 43 cooperates with the receiving plate 81, and the extension conveyor belt 11 transports the soil to the screen grid 61.
[0038] S2: The soil screen 61 filters out fine soil particles, which enter the soil bin 63 and await further processing. The roots that come onto the soil screen 61 have strong support and are relatively light, resulting in limited deformation. They get stuck on the soil screen 61. The separating claw 51 inserts between the soil screen 61 and lifts the roots from below. With the support of the soil screen baffle 62, the roots are moved backward into the hot roller 7 and await further processing. When there are more stones on the soil screen 61, the control handle 65 controls the tilt angle of the soil screen 61 forward, and the stones roll into the stone bin 64 and await disposal.
[0039] S3: The hot roller 7 presses and heats the root system, causing it to lose its activity and be sterilized. The sterilized root system enters through the top opening of the liquid preparation tank 91 and is crushed by the crushing blade 92. It then enters the soil tank 63 along with the fertilizer liquid in the liquid preparation tank 91. The stirring roller 12 in the soil tank 63 mixes the soil with the fertilizer liquid and backfills through the bottom opening of the soil tank 63.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
