Description

Technical Field

[0001] This invention relates to the field of turf stripping technology, and in particular to a turf stripping depth measuring device. Background Technology

[0002] Meadow ecosystems in high-altitude and cold regions are fragile and sensitive. Removing turf can minimize damage to the ecosystem and protect biodiversity. Removing turf from meadows in high-altitude and cold regions is a complex and delicate project aimed at protecting the ecological environment of these areas while meeting the needs of engineering construction.

[0003] In high-altitude and cold regions, the terrain is slightly undulating. Existing turf stripping equipment can only be used for stripping flat turf and cannot adjust the stripping blade according to the terrain. This results in inconsistent thickness of the stripped turf and easily damages the turf root system. Once the turf root system is damaged, the survival rate of the turf will be greatly reduced. When the turf stripping layer contains gravel, the stripping blade will come into contact with the gravel, which can easily damage the stripping blade and cause the gravel to be squeezed and embedded into the turf, resulting in damage to the turf structure and easy breakage of the turf.

Detailed Implementation

[0029] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0030] Example 1

[0031] A device for measuring the peeling depth of turf, such as Figures 1-3 As shown, the device includes a frame 1, a connecting frame 101 on the lower side of the frame 1, a peeling blade 102 slidably connected within the connecting frame 101, and an adjustment mechanism. The adjustment mechanism includes a mounting frame 201, which is symmetrically fixed to the frame 1. Squeezing plates A202 are symmetrically and horizontally slidably connected within the mounting frame 201, and an airbag A203 is provided for use with the squeezing plates A202. The airbag A203 is located between two adjacent squeezing plates A202. An air supply pipe 204 is fixedly connected inside the frame 201. One end of the air supply pipe 204 is connected to the air bag A203, and the other end of the air supply pipe 204 is connected to the air bag B205. An extrusion plate B206 that works with the air bag B205 is fixedly connected inside the mounting frame 201. An extrusion plate C207 that works with the air bag B205 is provided on one side of the extrusion plate B206. The air bag B205 is located between the adjacent extrusion plates B206 and C207. The mounting frame 201 also includes a depth surveying mechanism.

[0032] like Figures 2-4 As shown, the adjustment mechanism also includes a sleeve 301. The bottom of the mounting bracket 201 is fixedly connected to the sleeve 301. A manual telescopic rod 3011 is vertically slidably connected inside the sleeve 301. A limit pin 3012 is inserted through the outer wall of the sleeve 301. The outer wall of the fixed end of the manual telescopic rod 3011 has a limit hole that cooperates with the limit pin 3012. The limit pin 3012 can limit the manual telescopic rod 3011 by inserting into the limit hole. The telescopic end of the manual telescopic rod 3011 is rotatably connected to a traveling wheel. The fixed end of the manual telescopic rod 3011 is fixedly connected to a vertical shaft. A ring A302 is slidably sleeved on the outer wall of the vertical shaft. A damping ring is embedded and fixedly connected to the inner wall of the ring A302. The outer wall of the ring A302 is slidably connected to the inner wall of the sleeve 301. A lifting shaft 303 is vertically slidably connected inside the sleeve 301. An elastic element A is provided between the ring A302 and the lifting shaft 303. The elastic element A is a return spring. The top end of the lifting shaft 303 slides through the mounting frame 201 and is fixedly connected to the guide frame 304. A V-shaped groove is symmetrically opened through one side of the guide frame 304. A vertical rod 305 is symmetrically slidably connected inside the mounting frame 201. The vertical rod 305 is fixedly connected to the extrusion plate A202. A convex shaft is fixedly connected to one side of the vertical rod 305. One end of the convex shaft is inserted into the V-shaped groove of the guide frame 304 and slides therein. When the guide frame 304 moves vertically, the extrusion plate A202 can extrude the airbag A203.

[0033] like Figure 2 and Figure 4As shown, the adjustment mechanism also includes a piston tube 306. The piston tube 306 is fixedly connected inside the mounting bracket 201. The top of the piston tube 306 has a through hole and a sliding groove communicating with the through hole. A sealing plate 307 is slidably connected inside the sliding groove. An elastic element B, which is a compression spring, is provided between the sealing plate 307 and the sliding groove. The sealing plate 307 is fixedly connected to the extrusion plate C207 by an L-shaped rod. When the airbag B205 inflates, the sealing plate 307 can slide horizontally. A trigger switch 308 that works with the sealing plate 307 is installed on the top of the piston tube 306. A piston rod 309 is slidably connected to the inner wall of the piston tube 306. When the sealing plate 307 blocks the through hole of the piston tube 306, it can limit the piston rod 309.

[0034] like Figure 5 As shown, the adjustment mechanism also includes a movable plate 401. The movable plate 401 is fixedly sleeved on the outer wall of the fixed end of the manual telescopic rod 3011. One end of the piston rod 309 is slidably connected to the movable plate 401 through it. A ring B402 is fixedly connected to the outer wall of the piston rod 309. The ring B402 is located on the upper side of the movable plate 401. An elastic element C is provided between the movable plate 401 and the ring B402. The elastic element C is a return spring.

[0035] like Figure 5 As shown, the adjustment mechanism also includes a special-shaped frame 501. The special-shaped frame 501 is provided on the upper side of the connecting frame 101. The telescopic shafts A502 are symmetrically fixed on both sides of the special-shaped frame 501. The telescopic end of the telescopic shaft A502 is hinged to the bottom end of the corresponding piston rod 309. A gas valve 503 is installed on the outer wall of the fixed end of the telescopic shaft A502. The gas valve 503 is electrically connected to the trigger switch 308. When the gas valve 503 is opened, the telescopic end of the telescopic shaft A502 can move.

[0036] like Figure 5 and Figure 6 As shown, the depth surveying mechanism includes a connecting frame 601. The connecting frame 601 is vertically and slidably connected through the irregular frame 501. A laser surveying instrument 602 is installed on the bottom front side of the connecting frame 601. The laser surveying instrument 602 is used to survey the leaf length of the turf. An electric push rod 603 is installed on the irregular frame 501. The electric push rod 603 is electrically connected to the laser surveying instrument 602. The telescopic end of the electric push rod 603 is fixedly connected to the connecting frame 601. A rotating block 604 is symmetrically fixedly connected to the bottom end of the connecting frame 601. A rotating shaft 6041 is symmetrically fixedly connected to both sides of the connecting frame 101. The rotating shaft 6041 is rotatably connected to the rotating block 604 through the connecting frame 101.

[0037] like Figure 6 and Figure 7As shown, the depth surveying mechanism also includes a telescopic shaft B605. The telescopic shaft B605 is fixedly connected to the outer wall of the rotating shaft 6041. A groove is provided on the front side of the outer wall of the rotating block 604. The fixed end of the telescopic shaft B605 is inserted into the groove and slides therein. A hydraulic cylinder 606 is installed on the irregular frame 501. The hydraulic cylinder 606 is electrically connected to the laser surveying instrument 602. The telescopic end of the hydraulic cylinder 606 is fixedly connected to the control frame 607. The telescopic end of the telescopic shaft B605 is hinged to the control frame 607. When the telescopic end of the hydraulic cylinder 606 moves, the peeling blade 102 can rotate around the connection between the rotating block 604 and the rotating shaft 6041 as the center.

[0038] Initially, the limiting pin 3012 is inserted into the limiting hole of the corresponding manual telescopic rod 3011, and the telescopic ends of the two manual telescopic rods 3011 are on the same horizontal plane. The airbag A203 is inflated, and the airbag A203 limits the vertical rod 305 through the adjacent extrusion plate A202. The vertical rod 305 is squeezed against the inner wall of the V-groove of the guide frame 304 through its convex shaft, thereby limiting the lifting shaft 303 through the guide frame 304. The elastic element A is in the released state. First, the whole device is placed on the turf, and the frame 1 is connected to the trolley in the prior art. The turf under the peeling blade 102 is removed so that the peeling blade 102 is in contact with the soil at the turf peeling point. When the whole device is placed on the turf, the two manual telescopic rods 3011... When the walking wheels come into contact with the turf, the slight undulations on the surface of the alpine meadow turf cause the entire device to tilt. At this point, staff adjust the telescopic ends of the two manual telescopic rods 3011 to keep the device level. Then, the two limit pins 3012 are pulled out of their corresponding limit holes on the manual telescopic rods 3011, allowing the rods to move freely. The frame 1 is then moved by a trolley, causing the peeling blade 102 to peel the turf. Simultaneously, the frame 1, through the mounting bracket 201, moves the sleeve 301, which in turn moves the corresponding manual telescopic rods 3011. The telescopic ends of the two manual telescopic rods 3011 then drive the corresponding walking wheels to move along the turf. The fixed ends of the piston rods 1 and 2 respectively press against the outer walls of the adjacent piston rods 309 through the corresponding movable plates 401. The two piston rods 309 are subjected to force and drive the irregular frame 501 to move through the corresponding telescopic shafts A502. The irregular frame 501 drives the two rotating blocks 604 to move through the connecting frame 601. The two rotating blocks 604 drive the connecting frame 101 to move through the corresponding rotating shafts 6041. The connecting frame 101 drives the peeling blade 102 to peel off the turf. Since the surface of the turf has slight undulations, when the walking wheels walk in contact with the turf, they will drive the corresponding manual telescopic rod 3011 to slide vertically along the sleeve 301. The manual telescopic rod 3011 drives the vertical shaft on it to move vertically. The damping ring in the ring A302 is affected by the friction of the vertical shaft. The damping ring A302 slides along the inner wall of the sleeve 301. When the ring A302 moves upward, the elastic element A applies a pushing force to the ring A302; when the ring A302 moves downward, the elastic element A applies a pulling force to the ring A302. Due to the characteristics of the damping ring and the force applied by the elastic element A to the ring A302, the movement speed of the ring A302 is slower than the movement speed of the vertical axis. The movement range of the ring A302 is smaller than the vertical axis movement range of the manual telescopic rod 3011. At this time, the ring A302 slides slightly vertically. When the ring A302 slides vertically, it applies a very small pulling or pushing force to the adjacent lifting shaft 303 through the elastic element A. The lifting shaft 303 is driven by the force to slightly move the corresponding guide frame 304 upward or downward.The guide frame 304, through its V-shaped groove, presses against the convex shafts of two adjacent vertical rods 305, causing the two vertical rods 305 to drive the two pressing plates A202 to move closer to each other. During this movement, the two pressing plates A202 press against the outer wall of the airbag A203. It is worth noting that at this time, the pressure inside the airbag A203 is greater than the force exerted by the elastic element A on the lifting shaft 303. The reaction force exerted by the airbag A203 on the two pressing plates A202 is greater than the pressing force exerted by the two pressing plates A202 on the airbag A203. Therefore, the airbag A203 does not... The mechanism retracts, and the two extrusion plates A202 limit the guide frame 304 via the convex shafts of the two vertical rods 305, thus preventing the lifting shaft 303 from moving. The lifting shaft 303 applies tension or thrust to the ring A302 via the elastic element A. Under the action of the elastic element A, the ring A302 slides vertically within the sleeve 301. This prevents the peeling blade 102 from rotating even when there are slight undulations on the turf surface, and makes the peeled turf smoother. Repeating the above steps achieves the same effect.

[0039] When the entire device moves to a location with significant turf undulation, the angle of the stripping blade 102 needs to be adjusted to prevent inconsistent turf thickness stripping, which could lead to wasted soil resources or damage to the turf roots. Taking one of the manual telescopic rods 3011 as an example, when the traveling wheel of the manual telescopic rod 3011 moves to a location with significant turf undulation, the traveling wheel will drive the manual telescopic rod 3011 to move rapidly upward or downward a long distance. The manual telescopic rod 3011 will drive its vertical shaft to move rapidly upward or downward a long distance. The damping ring inside the ring A302 will move rapidly upward or downward a long distance under the action of the vertical shaft. Because the ring A302 is moving a long distance at this time, the ring A302 applies a pushing or pulling force to the lifting shaft 303 through the elastic element A. The pressure increases, thus increasing the squeezing force of the compression plate A202 on the airbag A203. At this point, the squeezing force of the compression plate A202 on the airbag A203 is greater than the reaction force exerted by the airbag A203 on the compression plate A202. The airbag A203 contracts under pressure and its volume decreases. Some of the air inside the airbag A203 enters the corresponding airbag B205 through the air supply pipe 204. The airbag B205 inflates slightly. Due to the material resistance of the airbags A203 and B205 and the inertia of airflow, when the airbag A203 is compressed and contracted, it will also contract itself, thereby accelerating the airflow speed. Meanwhile, the airbag B205 continues to expand slowly. When the airbag A203 contracts to a certain extent, the remaining air inside the airbag A203 will... The air supply tube 204 quickly enters the corresponding airbag B205, causing the airbag B205 to inflate rapidly. During this rapid inflation, the airbag B205 first contacts the corresponding compression plate C207, which compresses it. The airbag B205 tilts towards the corresponding compression plate B206 until it contacts it. The compression plate B206 provides support for the airbag B205, thus applying pressure to the compression plate C207. The pressure on the compression plate C207, through its L-shaped rod, causes the sealing plate 307 to slide horizontally along the groove of the piston tube 306. The elastic element B contracts under pressure, and the sealing plate 307 no longer obstructs the through-hole of the piston tube 306 after sliding. The manual telescopic rod 30... 11. While rapidly moving upward or downward a long distance, it drives the corresponding movable plate 401 to rapidly move upward or downward a long distance. After the movable plate 401 moves, the distance between it and the corresponding ring B402 increases or decreases, and the elastic element C extends or contracts under force. The elastic element C applies a pushing or pulling force to the piston rod 309 through the ring B402. When the through hole of the piston tube 306 is blocked by the sealing plate 307, the air volume in the piston tube 306 remains stable, and the piston rod 309 cannot slide in the piston tube 306, thus preventing the ring B402 from moving. When the through hole of the piston tube 306 is no longer blocked by the sealing plate 307, the air in the piston tube 306 can be discharged, or outside air can be drawn in through the through hole, thus allowing the piston rod 309 to move.At this time, the piston rod 309, affected by the pushing or pulling force of the elastic element C, slides upward or downward within the piston tube 306. The piston rod 309 applies a pushing or pulling force to the telescopic end of the adjacent telescopic shaft A502. The telescopic shaft A502, under this force, drives the irregular frame 501 to rotate around the connection point between the other telescopic shaft A502 and the corresponding piston rod 309. The irregular frame 501, through the connecting frame 601, drives the two rotating blocks 604 to move. The two rotating blocks 604, through the two rotating shafts 6041, drive the connecting frame 101 to rotate. The connecting frame 101 drives the peeling blade 102 to rotate, thereby allowing the peeling blade 102 to adapt to the undulations of the turf and adjust its angle accordingly.

[0040] Initially, both air valves 503 are closed, and the telescopic ends of both telescopic shafts A502 are in a retracted state. After the sealing plate 307 slides, it contacts and presses against the corresponding trigger switch 308. Upon being pressed, the trigger switch 308 opens the adjacent air valve 503. When one of the piston rods 309 moves vertically, the air valve 503 on the adjacent telescopic shaft A502 opens, allowing the telescopic end of the telescopic shaft A502 to move. The telescopic end of the telescopic shaft A502 extends with the movement of the piston rod 309 until the elastic element C is fully released or retracted. The elastic element C no longer applies pushing or pulling force to the piston rod 309 through the ring B402, thus preventing the peeling knife 102 from rotating. During the vertical movement of the piston rod 309, the elastic element A gradually releases or retracts, causing the ring A302 to slide along the outer wall of the vertical axis of the corresponding manual telescopic rod 3011. The ring A302 applies force to the lifting shaft 303 through the elastic element A. As the pushing or pulling force gradually decreases, the squeezing force of the squeezing plate A202 on the airbag A203 gradually decreases. When the squeezing force of the squeezing plate A202 on the airbag A203 is less than the squeezing force of the squeezing plate C207 on the airbag B205, the elastic element B gradually releases and drives the sealing plate 307 to slide back to its original position. After the sealing plate 307 is reset, it blocks the through hole of the piston tube 306, thereby preventing the piston rod 309 from moving. Furthermore, the sealing plate 307 no longer contacts the corresponding trigger switch 308, and the adjacent air valve 503 closes, preventing the telescopic end of the telescopic shaft A502 from moving. This keeps the angle of the peeling knife 102 stable. Subsequently, under the action of the above principle, the air in the airbag B205 quickly enters the airbag A203 through the air supply pipe 204, thereby completing the angle adjustment of the peeling knife 102. When the traveling wheels of the two manual telescopic rods 3011 encounter the above situation again, the above steps can be repeated to achieve the same effect.

[0041] During the turf stripping process, the connecting frame 601 drives the laser surveyor 602 to move, allowing the laser surveyor 602 to survey the turf in front of the stripping blade 102. The laser surveyor 602 determines the root depth of the turf based on the length of the turf blades. When the turf blades are long, the laser surveyor 602 controls the extension of the electric push rod 603 and the extension of the hydraulic cylinder 606. The extension of the electric push rod 603 causes the connecting frame 601 to descend. The connecting frame 601, through two rotating blocks 604 and two rotating shafts 6041, causes the connecting frame 101 to descend. The connecting frame 101 causes the stripping blade 102 to descend. Simultaneously, the extension of the hydraulic cylinder 606, through the control frame 607, causes the extension of the two extension shafts B605 to descend. 5. The force drives the rotating shaft 6041 to rotate, and the telescopic end of the telescopic shaft B605 extends. The two rotating shafts 6041 together drive the peeling blade 102 to rotate downward through the connecting frame 101. When the turf blades are short, the laser surveying instrument 602 controls the telescopic end of the electric push rod 603 to retract, thereby causing the connecting frame 101 to drive the peeling blade 102 to lift upward and rotate upward. By tilting the peeling blade 102, it is easier for the peeling blade 102 to move up and down under the turf, preventing the peeling blade 102 from being hard-pressed against the soil under the turf peeling surface, and preventing the peeling blade 102 from damaging the turf roots when it moves. Then, the telescopic end of the hydraulic cylinder 606 slowly extends or retracts to reset, thereby causing the peeling blade 102 to rotate and reset.

[0042] Example 2

[0043] like Figures 8-10 As shown, it also includes a stone cleaning mechanism, which includes a drive assembly 701. The drive assembly 701 is installed inside the rear side of the connecting frame 101. The drive assembly 701 consists of a drive motor, a disc, a connecting rod, and a U-shaped frame. The drive motor is installed inside the rear side of the connecting frame 101. The disc is fixedly connected to the output shaft of the drive motor. The connecting rod is rotatably connected to the top of the disc. The U-shaped frame is fixedly connected to the rear side of the peeling blade 102. The connecting rod is rotatably connected to the top of the U-shaped frame. A sliding groove is provided on the rear side of the peeling blade 102. A horizontal plate 702 is horizontally slidably connected in the sliding groove. A rotating frame 703 is hinged to the bottom of the horizontal plate 702. Several evenly distributed probes 704 are fixedly connected to the bottom of the rotating frame 703.

[0044] like Figure 10 As shown, the gravel cleaning mechanism also includes a guide shaft 801. The guide shaft 801 is fixedly connected to the top of the horizontal plate 702. A wave groove is opened in the connecting frame 101. The telescopic end of the guide shaft 801 is inserted into the wave groove and slides in it. When the horizontal plate 702 moves forward, the guide shaft 801 can make the horizontal plate 702 reciprocate horizontally under the action of the wave groove.

[0045] For example, 10 and Figure 11As shown, the gravel cleaning mechanism also includes a guide rail 901. The guide rail 901 is fixedly connected inside the connecting frame 101. The guide rail 901 is located on the upper side of the horizontal plate 702. A sliding frame 902 is slidably connected inside the guide rail 901. The sliding frame 902 is vertically slidably connected to the horizontal plate 702 through the guide rail. The sliding frame 902 is inserted into the rotating frame 703 and slides inside it.

[0046] Initially, the sliding frame 902 contacts the rear end of the inner wall of the guide rail 901. After adjusting the telescopic end of the manual telescopic rod 3011, the drive motor in the drive assembly 701 is started. The output shaft of the drive motor drives the disc to rotate. The disc, through the connecting rod and the U-shaped frame, drives the peeling blade 102 to slide horizontally back and forth along the connecting frame 101, so that the peeling blade 102 peels the turf. When the peeling blade 102 moves forward, it drives the horizontal plate 702 to move forward. The horizontal plate 702 drives several probes 704 to move forward through the rotating frame 703, and drives the guide shaft 801 and the sliding frame 902 to move forward. The telescopic end of the guide shaft 801 slides along the wave groove of the connecting frame 101, and drives the horizontal plate 702 to move forward along the wave groove of the connecting frame 101. The sliding groove of the peeling blade 102 reciprocates horizontally. The horizontal plate 702 drives several probes 704 to reciprocate horizontally via the rotating frame 703, which in turn drives the sliding frame 902 to reciprocate horizontally on the guide rail 901. The forward movement of the probes 704 can crush the gravel on the turf peeling surface. When the gravel is relatively hard, the probes 704 can push the gravel forward to prevent the peeling blade 102 from contacting the gravel, which could damage the peeling blade 102, or cause the gravel to be lifted by the peeling blade 102 and break the turf. The horizontal reciprocating movement of the probes 704 can initially separate the turf peeling surface from the soil, making the turf loose and facilitating the peeling blade 102 to peel the turf. When the sliding frame 902 slides to the guide rail 901, the turf peeling process continues. At the upper corner of the guide rail 901, the sliding frame 902 slides diagonally downwards under the pressure of the inner wall of the guide rail 901. The sliding frame 902 presses against the inner wall of the rotating frame 703, causing the rotating frame 703 to drive several probes 704 to rotate downwards. This presses the pushed gravel downwards, preventing uncrushed gravel from contacting the stripping blade 102, which could damage the stripping blade 102 or cause damage to the turf. This continues until the sliding frame 902 slides to the lower corner of the guide rail 901. The sliding frame 902 then slides horizontally along the guide rail 901 and no longer presses against the inner wall of the rotating frame 703. This causes several probes 704 to move forward while maintaining an inclined state. The probes 704 push the gravel forward again. When the stripping blade 102 moves backwards... The peeling blade 102 drives the horizontal plate 702 to move rearward. The horizontal plate 702, through the rotating frame 703, drives several probes 704 to move rearward, and also drives the guide shaft 801 and the sliding frame 902 to move rearward. Under the action of the corrugated groove, the telescopic end of the guide shaft 801 causes the probes 704, the guide shaft 801, and the sliding frame 902 to reciprocate horizontally. The sliding frame 902 first slides horizontally along the inner wall of the guide rail 901, thereby causing the probes 704 to move horizontally, thus preventing the probes 704 from rotating and resetting too quickly, causing the crushed stone to move with the probes 704. When the sliding frame 902 slides to the lower corner of the guide rail 901, the probes 704 completely detach from the crushed stone, and the inner wall of the guide rail 901 squeezes the sliding frame 902.The sliding frame 902 is lifted upwards to reset. By pressing against the inner wall of the rotating frame 703, the sliding frame 902 causes the rotating frame 703 to rotate and reset several probes 704. Repeating this process achieves the same effect.
