Description

Technical Field

[0001] This invention relates to the field of soil and water conservation technology in high-altitude and cold regions, and in particular to an apparatus and method for stripping grassland from sandy loam substrate soil in high-altitude and cold regions. Background Technology

[0002] In my country's high-altitude cold regions, which are cold plateau areas with an altitude of over 3,000 meters, there are large areas of alpine meadows. When road construction is carried out in these areas, it is inevitable that the grassland will be damaged. Therefore, the grassland at the construction site is usually stripped and preserved before construction. After the construction is completed, the grassland is repaved to protect the soil and water balance of the high-altitude cold regions.

[0003] However, due to recent climate change, land desertification and other issues have intensified, leading to a significant increase in the area of ​​sandy loam substrate grasslands. Sandy loam substrate grasslands have a high sand content and are loose, making them prone to cracking and disintegration during the turf stripping process, hindering complete stripping and transport. Existing turf stripping devices, such as CN205921929U "Turf Transplanter," do not consider the loose characteristics of sandy loam substrates. They typically roll up the stripped turf before transferring it to a transport device for temporary conservation. Rolling up the stripped turf directly damages the already loose turf, resulting in poor stripping efficiency. Furthermore, if this device is used to strip turf from sandy loam substrates in high-altitude, cold regions, the area that can be stripped each time is limited to the area the device can hold without rolling, resulting in low stripping efficiency and making it unsuitable for stripping sandy loam substrate grasslands in high-altitude, cold regions. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an apparatus and method for stripping grassland on sandy loam substrate soil in high-altitude and cold regions. It is mainly used for stripping turf from grassland on sandy loam substrate soil in high-altitude and cold regions, so as to achieve the purpose of completely stripping the grassland and transferring it to the grassland transport device.

[0005] The present invention discloses a device for stripping grassland in sandy loam substrate soil in high-altitude and cold regions, comprising a frame, a cutting mechanism, a stripping mechanism and a spraying mechanism;

[0006] The frame is a four-sided enclosed frame. A spraying mechanism connected to the frame is located on the top of the frame. A cutting mechanism is located below the frame and runs along the frame. The cutting mechanism includes a cutting blade that surrounds the frame and is vertically positioned at the bottom of the frame with its tip facing the ground. A connecting pressure rod for connecting to a hoisting mechanism is located at the top of the frame. The two ends of the connecting pressure rod are connected to two parallel surfaces of the frame. The connecting pressure rod also has a connecting through hole.

[0007] The peeling mechanism is located inside the frame. The peeling mechanism includes a peeling blade and a drive mechanism. The size of the peeling blade is adapted to the size of the bottom of the frame. The frame is provided with a moving track for moving the peeling blade. The moving track includes a connected storage track and a sliding track. The sliding track is located below two parallel sides of the frame. The storage track is perpendicular to the sliding track and located on one side of the frame. The peeling blade is slidably disposed within the moving track. The peeling blade includes a front cutting section, a transport section, and a rear cutting section connected in sequence. The tip of the front cutting section faces the dual-output shaft motor, and the tip of the rear cutting section is opposite to the tip of the front cutting section. The front cutting section has first positioning shafts at both ends, and the rear cutting section has second positioning shafts at both ends. The first positioning shaft has a first through hole, and the second positioning shaft has a second through hole.

[0008] The drive mechanism includes a dual-output shaft motor, a horizontal pull steel rope, and a return steel rope. The dual-output shaft motor is located on the side of the frame away from the storage track, and its left and right output ends are aligned with the sliding tracks installed within the frame. A horizontal pull steel rope is wound around each of the left and right output ends of the dual-output shaft motor. One end of the horizontal pull steel rope passes through the frame and is wound around the dual-output shaft motor, while the other end passes through a first through hole and connects to a first positioning shaft. A return steel rope is also wound around the left and right output shafts of the dual-output shaft motor. One end of the return steel rope passes through the frame and is wound around the dual-output shaft motor, while the other end passes through a second through hole and connects to a second positioning shaft. The horizontal pull steel rope and the return steel rope are wound in opposite directions.

[0009] Furthermore, the front cutting section, the rear cutting section, and the transport section are detachably connected. The front cutting section, the rear cutting section, and the transport section are hexagonal prisms. A first mounting block is provided on the side where the front cutting section connects to the transport section. The first mounting block is located at both ends of the cutting section and has a first mounting hole. A first mounting groove is provided on the side where the rear cutting section connects to the transport section. A second mounting hole is provided at both ends of the first mounting groove. A second mounting groove is provided on the side of the transport section near the front cutting section. A third mounting hole is provided at both ends of the second mounting groove. A connecting rod is provided in the second mounting groove, with its left and right ends passing through the first mounting hole and connecting to the third mounting hole on the first mounting block. A second mounting block is provided on the side of the transport section near the rear cutting section. The second mounting block is located at both ends of the transport section and has a fourth mounting hole. A connecting rod is provided in the first mounting groove, with its left and right ends passing through the fourth mounting hole and connecting to the second mounting hole.

[0010] As a preferred embodiment, multiple transport sections are detachably connected between the front cutting section and the rear cutting section.

[0011] Furthermore, the spraying mechanism includes a spray tank, nozzles, and a spray tank control system. The bottom of the spray tank is connected to the frame, and multiple nozzles are evenly spaced on the spray tank and face downwards from the frame. The spray tank control system is electrically connected to the nozzle switch.

[0012] Furthermore, the cutting blade includes an inner blade and an outer blade, the lower end of the inner blade is connected to the lower end of the outer blade, and the inner blade and the outer blade together with the lower end of the frame connected to them form a triangle with the tip pointing downwards.

[0013] Furthermore, the outer side of the frame is provided with a connector that is aligned with the connecting pressure rod. The connector includes a first connecting block and a second connecting block that are respectively disposed on the outer side of the frame and connected to both ends of the connecting pressure rod. The first connecting block has a first threaded hole, and the second connecting block has a second threaded hole corresponding to the first threaded hole. The first connecting blocks and the second connecting blocks on two adjacent frames are connected, and a bolt is provided in the first threaded hole on one of the two adjacent frames. The bolt passes through the first threaded hole and is threadedly connected to the second threaded hole on the other frame.

[0014] This invention also discloses a method for stripping grassland from sandy loam substrate soil in high-altitude and cold regions, comprising the following steps:

[0015] Step 1: Delineate the area, separating unrelated areas, stripping and re-paving areas, and construction areas; clean up the stripping and re-paving areas; and clean up the stripped areas.

[0016] Step Two: Equipment Assembly;

[0017] The above-mentioned device for stripping sandy loam substrate soil grassland in high-altitude cold regions is connected to the hoisting mechanism. The hoisting mechanism’s hoisting line passes through the connecting through hole opened on the pressure-bearing connecting rod and is locked, and the soil stabilizer is filled into the spraying mechanism.

[0018] Step 3: Press down and cut;

[0019] The hoisting mechanism is used to drive the device for stripping grass in sandy loam substrate soil in high-altitude and cold regions, which was assembled in step two, to press down, so that the cutting mechanism cuts into the soil and the cutting section of the stripping blade stored in the storage track comes into contact with the grass.

[0020] Step 4: Remove the grass and spray soil stabilizer;

[0021] Turn on the dual-output shaft motor and set its rotation direction to forward. Retract the horizontal pull steel cable and release the pull-back steel cable. The stripping blade moves along the sliding track toward the dual-output shaft motor. The tip of the cutting section cuts into the soil. Under the traction of the horizontal pull steel cable, it cuts the grass roots and soil located in the soil, and drives the transport section to separate the cut grass from the original soil. During the cutting process, control the spraying mechanism to spray soil stabilizer onto the stripped grass below.

[0022] Step 5: Stripping complete; transport the stripped turf.

[0023] When the stripping blades move to cover the entire bottom of the frame, the grass stripping is complete. The hoisting mechanism then moves the hoisting rope upwards, and the hoisting rope, through the pressure-bearing connecting rod, moves the entire device used for stripping sandy loam substrate grass in high-altitude and cold regions upwards, away from the stripping area.

[0024] Furthermore, the equipment assembly in step two includes multiple devices arranged in rows for stripping sandy loam substrate soil and grassland in high-altitude and cold regions, with adjacent frames connected by connectors to form an integrated structure.

[0025] Furthermore, it also includes step six: unloading the stripped grass; turning on the dual output shaft motor, setting the rotation direction of the dual output shaft motor to reverse, retracting the pull-back steel cable, releasing the horizontal pull-back steel cable, and pulling the stripping blade out from the end away from the dual output shaft motor, while the stripped grass is unloaded from the side of the stripping blade closest to the dual output shaft motor.

[0026] As a preferred method, a film should be laid at the location where the unloaded grass was placed before unloading it in step six.

[0027] The beneficial effects of this invention are as follows: By adding targeted components suitable for sandy loam substrate grasslands, namely a frame-type machine and a tracked stripping blade that can cover the entire bottom of the frame, and in conjunction with a cutting mechanism located at the bottom of the frame, the device for stripping sandy loam substrate grasslands in high-altitude and cold regions can easily insert and cut the soil. The tracked stripping blade completely covers the bottom of the frame, effectively ensuring the integrity of the native meadow turf and soil. Furthermore, using an existing hoisting mechanism to hoist the device can improve the grassland stripping efficiency. During the cutting process, the spraying mechanism sprays a soil stabilizer onto the stripped grassland located inside the frame to solidify the sandy loam substrate grassland, preventing any impact on the integrity of the grassland during transportation or stripping. At the same time, nutrient solution can be added to the existing soil stabilizer to improve soil nutrients and increase the survival rate of subsequent grassland re-laying. Moreover, the device is simple to manufacture, has a low cost, and is suitable for stripping sandy loam substrate grasslands in high-altitude and cold regions. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below.

[0039] This invention provides a grass stripping device for sandy loam substrate soil in high-altitude and cold regions, mainly used for stripping turf from sandy loam substrate soil in these areas. It includes a frame 1, a cutting mechanism 3, a stripping mechanism 4, and a spraying mechanism 2. The frame 1 is a four-sided enclosed frame. The spraying mechanism 2 is connected to the top of the frame 1. The cutting mechanism 3 is located below the frame 1 and runs along its length. The cutting mechanism 3 includes cutting blades arranged around the frame 1, with the blades vertically positioned at the bottom of the frame 1 and their tips facing the ground. A connecting pressure rod 11 is located at the top of the frame 1 for connection to a hoisting mechanism. Both ends of the connecting pressure rod 11 are connected to two parallel surfaces of the frame 1. The connecting pressure rod 11 is also provided with a connecting through hole 12; the peeling mechanism 4 is disposed inside the frame 1; the peeling mechanism 4 includes a peeling blade 41 and a driving mechanism 42, the size of the peeling blade 41 is adapted to the size of the bottom of the frame 1, the frame 1 is provided with a moving track 14 for moving the peeling blade 41, the moving track 14 includes a connected storage track 141 and a sliding track 142, the sliding track 142 is disposed below the two parallel sides of the frame 1, the storage track 141 is perpendicular to the sliding track 142 and disposed on one side of the frame 1; the peeling blade 41 is slidably disposed in the moving track 14, the peeling blade 41 includes a front cutting section 411 connected in sequence. The frame consists of a transport section 412 and a rear cutting section 413. The tip of the front cutting section 411 faces the dual-output shaft motor 421, and the tip of the rear cutting section 413 is opposite to the tip of the front cutting section 411. The front cutting section 411 has a first positioning shaft 4111 at both ends, and the rear cutting section 413 has a second positioning shaft 4131 at both ends. The first positioning shaft 4111 has a first through hole 4112, and the second positioning shaft 4131 has a second through hole 4132. The drive mechanism 42 includes a dual-output shaft motor 421, a horizontal pull steel rope 422, and a return steel rope 423. The dual-output shaft motor 421 is located on the side of the frame 1 away from the storage track 141. The left and right output ends of the dual-output shaft motor 421 are aligned with the sliding rail 142 set in the frame 1, respectively. A horizontal pull steel rope 422 is wound around the left and right output ends of the dual-output shaft motor 421. One end of the horizontal pull steel rope 422 passes through the frame 1 and is wound around the dual-output shaft motor 421, and the other end passes through the first through hole 4112 and is connected to the first positioning shaft 4111. A return steel rope 423 is also wound around the left and right output shafts of the dual-output shaft motor 421. One end of the return steel rope 423 passes through the frame 1 and is wound around the dual-output shaft motor 421, and the other end passes through the second through hole 4132 and is connected to the second positioning shaft 4131. The horizontal pull steel rope 422 and the return steel rope 423 are wound in opposite directions.

[0040] like Figures 1-8 As shown, the grassland stripping device for sandy loam substrate soil in high-altitude cold regions provided by the present invention includes a frame 1, which is a frame-shaped structure enclosing the area on all four sides. A lower cutting mechanism 3 is arranged below the frame 1 along its shape. The lower cutting mechanism 3 includes a lower cutting blade, such as... Figure 1 , Figure 2 As shown, the cutting blade is arranged around the lower part of the frame 1 so that when the device cuts the soil, it can separate the edge of the stripped grass inside the frame 1 from the surrounding grass, so as to completely cut the grass inside the frame 1; the top of the frame 1 is provided with a connecting bearing rod 11, the two ends of the connecting bearing rod 11 are connected to the frame 1, and the connecting bearing rod is provided with a connecting through hole 12. The connecting through hole 12 can be connected to the lifting rope 13 of the external lifting mechanism, so that the existing lifting mechanism can be connected to the device for stripping grass in sandy loam substrate soil in high-altitude cold regions, improving the ease of use of the device; Figures 2-6 As shown, when not in use, the stripping blade 41 can be stored in the storage track 141 located on one side of the frame 1. When in use, the stripping blade 41 can slide along the moving track 14 under the drive of the dual output shaft motor 421. After entering the sliding track 142, the tip of the front cutting section 411 faces the dual output shaft motor 421 and penetrates into the soil. Driven by the horizontal tension steel cable 422, it moves towards the dual output shaft motor 421, thereby cutting the grass inside the frame 1. When the tip of the front cutting section 411 contacts the lower cutting blade, the stripping of the grass inside the frame 1 is completed. The size of the stripping blade 41 is adapted to the size of the bottom of the frame 1, so that the grass stripped by the front cutting section 411 will be directly placed on the transport section 412 or the rear cutting section 413. When the stripping blade 41 finishes stripping the grass inside the frame 1, the rear cutting section 412... The tip of the cutting segment 413 also connects with the lower cutting blade, that is, the lower part of the frame 1 is completely enclosed by the stripping blade 41, and the stripped grass is located above the stripping blade 41 to ensure that the stripped grass is not damaged due to height difference, and to ensure the integrity of the stripped grass during the stripping and transportation process; at the same time as stripping the grass, the spraying mechanism 2 sprays soil stabilizer on the grass inside the frame 1 to temporarily reinforce the stripped sandy loam substrate grass, ensuring its integrity during the stripping and transportation process; a dual-output shaft motor 421 is used to pull the tracked stripping blade 41 to strip the turf, and after the turf is stripped, it reverses to pull the tracked stripping blade 41 back in the opposite direction to complete the unloading and loading of the turf or placement in a designated location; the horizontal pull steel rope 422 and the return steel rope 423 are wound in opposite directions, such as Figure 4 , Figure 5 The shown stripping blade 41 and the dual-output shaft motor 421 are connected in the following direction of movement: when the grass needs to be stripped from the grass inside the frame 1, the dual-output shaft motor 421 rotates forward, as shown in the diagram. Figure 4As shown, the horizontal pull steel cable 422 is retracted, and the pullback steel cable 423 is released, thereby driving the entire stripping blade 41 to move towards the dual output shaft motor 421 to achieve the purpose of cutting and stripping the grass, and to close the bottom of the frame 1, thus ensuring that all the stripped grass is above the stripping blade 41 and its integrity is maintained; when it is necessary to unload the stripped grass in the frame 1, the dual output shaft motor 421 reverses, as... Figure 5 As shown, the pullback steel rope 423 is retracted and the horizontal pull steel rope 422 is released, which in turn drives the entire stripping blade 41 to move away from the dual output shaft motor 421, so that a gap is slowly opened between the stripping blade 41 and the dual output shaft motor 421, allowing the grass on the stripping blade 41 to be slowly unloaded from the gap and placed in the designated placement location.

[0041] By adding targeted components suitable for sandy loam substrate grasslands, namely a frame-type frame 1 and a tracked stripping blade 41 that can cover the entire bottom of the frame 1, and in conjunction with the cutting mechanism 3 located at the bottom of the frame 1, the device for stripping sandy loam substrate grasslands in high-altitude and cold regions can easily insert and cut the soil. The tracked stripping blade 41 completely covers the bottom of the frame 1, effectively ensuring the integrity of the native meadow turf and soil. In addition, the device can be hoisted by existing hoisting mechanisms to improve grassland stripping efficiency. During the cutting process, the spraying mechanism 2 sprays soil stabilizer onto the stripped grassland located inside the frame 1 to solidify the sandy loam substrate grassland and prevent the integrity of the grassland from being affected during transportation or stripping. At the same time, nutrient solution can be added to the existing soil stabilizer to improve soil nutrients and increase the survival rate of subsequent grassland re-laying. Moreover, the device is simple to manufacture, low in cost, and suitable for stripping sandy loam substrate grasslands in high-altitude and cold regions.

[0042] To facilitate the replacement and maintenance of the stripping blade 41, such as Figures 3-5As shown, the front cutting section 411, the rear cutting section 413, and the transport section 412 are detachably connected. The front cutting section 411, the rear cutting section 413, and the transport section 412 are hexagonal prisms. A first mounting block 4113 is provided on the side of the front cutting section 411 where it connects to the transport section 412. The first mounting block 4113 is located at both ends of the cutting section and has first mounting holes 4114. A first mounting groove 4133 is provided on the side of the rear cutting section 413 where it connects to the transport section 412. Second mounting holes 4134 are provided at both ends of the first mounting groove 4133. A second mounting groove 4121 is provided on the side of the transport section 412 near the front cutting section 411. The second mounting groove 4121 has third mounting holes 4122 at both ends. A connecting rod 414, with its left and right ends passing through the first mounting hole 4114 on the first mounting block 4113 and connecting to the third mounting hole 4122, is provided within the second mounting groove 4121. A second mounting block 4123 is provided on the side of the transport section 412 near the rear cutting section 413. The second mounting block 4123 is located at both ends of the transport section 412 and has fourth mounting holes 4124. A connecting rod 414, with its left and right ends passing through the fourth mounting hole 4124 and connecting to the second mounting hole 4134, is provided within the first mounting groove 4133. As a preferred embodiment, to facilitate adjustment of the stripping blade 41's length to accommodate different sizes of grass stripping, such as... Figures 4-6 As shown, multiple transport sections 412 are detachably connected between the front cutting section 411 and the rear cutting section 413. Specifically, the detachable connection method between the transport sections 412 can refer to the detachable connection method between the cutting section and the transport section 412, that is, multiple identical transport sections 412 with the same orientation are set, and the multiple transport sections 412 are connected by connecting rods 414. This allows the number of transport sections 412 to be installed according to the size of the bottom of the frame 1, so that the stripping blade 41 can be used for stripping grass on frames 1 of different lengths, saving costs and stripping grass efficiently.

[0043] To achieve uniform spraying of soil stabilizing agent onto the grass stripped from frame 1, such as... Figure 1 , Figure 7As shown, the spraying mechanism 2 includes a spray tank 21, nozzles 22, and a spray tank control system 23. The bottom of the spray tank 21 is connected to the frame 1. Multiple nozzles 22 are evenly spaced on the spray tank 21 and face downwards from the frame 1. The spray tank control system 23 is electrically connected to the on / off switch of the nozzles 22. The spray tank 21 is detachably mounted on the frame 1, allowing for the use of tanks of different sizes according to different needs. The spray tank 21 can be designed to be transparent to observe the application of the soil stabilizer in the tank, even when adding soil stabilizer. The spray tank 21 has a spray tank cap 211 for adding soil stabilizer and multiple nozzles for spraying soil stabilizer. The spray nozzles 22 each have an independent switch. These independent switches are electrically connected to the spray tank control system 23. The opening and closing of the nozzles 22 are controlled by the spray tank control system 23. This control system 23 can be an existing switch control system, which can control the switch status through various signals such as radio waves and wired transmission. When using the spraying mechanism 2, a certain number of nozzles 22 at different intervals can be opened according to the area of ​​the grassland inside the frame 1 and the amount of soil stabilizer required, so as to achieve a temporary stabilization effect on the sandy loam substrate. This ensures the stabilization effect, avoids waste, and saves the labor cost of manual spraying.

[0044] To allow the cutting blade to easily cut into the soil, such as Figure 1 , Figure 2 As shown, the cutting blade includes an inner blade 32 and an outer blade 31. The lower end of the inner blade 32 is connected to the lower end of the outer blade 31. The inner blade 32 and the outer blade 31, together with the lower end of the frame 1 connected to them, form a triangle with their tips pointing downwards. By setting the inner blade 32 and the outer blade 31 to be inclined to each other, and connecting the tips of the inner blade 32 and the outer blade 31 to each other, the inner blade 32 and the outer blade 31, together with the lower end of the frame 1, form a triangle with their tips pointing downwards. When the frame 1 is pressed down as a whole and cuts into the soil, the inclined blades... The inner blade 32 and outer blade 31 are inclined at an angle to the soil, reducing the cutting area and the resistance to cutting into the soil. At the same time, the inner and outer sides of the frame 1 cut in simultaneously, so that the edge of the grass to be peeled inside the frame 1 can be completely cut off from the soil. The grass peeled by the peeling mechanism 4 will not be unable to completely separate from the soil due to the edge being cut off, thus reducing the integrity of the peeled grass. The dimensions of the inner blade 32 and outer blade 31 are determined according to the root length and thickness of the grass to be cut.

[0045] To improve the efficiency of grassland stripping and achieve simultaneous stripping of multiple rectangular grasslands, such as... Figure 1 , Figure 8As shown, the outer side of the frame 1 is provided with a connector 15 located on the same straight line as the connecting pressure rod 11. The connector 15 includes a first connecting block 151 and a second connecting block 152 respectively disposed on the outer side of the frame 1 connected to both ends of the connecting pressure rod 11. The first connecting block 151 has a first threaded hole 1511, and the second connecting block 152 has a second threaded hole 1521 corresponding to the first threaded hole 1511. The first connecting blocks 151 and second connecting blocks 152 on two adjacent frames 1 are connected, and a bolt is provided in the first threaded hole 1511 of one of the two adjacent frames 1. The bolt passes through the first threaded hole 1511 and is threadedly connected to the second threaded hole 1521 on the other frame 1. Figure 1 As shown, the first connecting block 151 and the second connecting block 152 are respectively set on both sides of the frame 1 and are on the same straight line as the connecting pressure rod 11. The first connecting block 151 is provided with a first threaded hole 1511, and the second connecting block 152 is provided with a second threaded hole 1521. When two adjacent frames 1 are assembled and spliced, the first connecting block 151 on one frame 1 is aligned with the second connecting block 152 on the other frame 1, so that the first threaded hole 1511 and the second threaded hole 1521 are aligned. Then, they are connected with bolts. The number of frames 1 spliced ​​is selected according to the actual area of ​​grass to be stripped, but attention should be paid to unifying the stripping direction of the grass.

[0046] This invention also discloses a method for stripping grassland from sandy loam substrate soil in high-altitude and cold regions, comprising the following steps:

[0047] Step 1: Delineate the area, dividing it into irrelevant area 51, stripping and re-paving area 52, and construction area 53, and clean up stripping and re-paving area 52;

[0048] Divide the grassland area into zones, such as Figure 9 As shown, the grassland area is divided into an unrelated area 51, a stripping and re-laying area 52, and an engineering construction area 53. After the lines are drawn, the area to be stripped is cleaned up. Specifically, the grassland area to be stripped is divided into zones according to production and construction needs, and then the areas to be stripped are marked according to the difficulty of stripping and the distance from the transportation road.

[0049] Marking the areas ensures a clear stripping path during turf removal, without hindering subsequent construction and allowing for an orderly stripping process. After marking, debris in the stripping area should be cleared to avoid affecting the stripping effect and equipment access.

[0050] Step Two: Equipment Assembly;

[0051] The aforementioned device for stripping sandy loam substrate grassland in high-altitude and cold regions is connected to a hoisting mechanism. The hoisting mechanism's lifting line passes through the connecting through-hole 12 on the pressure-bearing connecting rod 414 and is locked. Soil stabilizer is then filled into the spraying mechanism 2. Figure 1 As shown, the hoisting cable of the hoisting mechanism is passed through the connecting through hole 12 opened on the pressure connecting rod 414, and then the hoisting rope 13 is locked with an existing wire rope locker to prevent the device for stripping sandy loam substrate grassland in high-altitude cold regions from detaching from the hoisting mechanism or from becoming unbalanced during use. The hoisting mechanism can be an existing bucket excavator or crane, which can lift and lower the load. Such hoisting mechanisms are suitable for various terrain environments and have strong load-bearing capacity, and can lift large-sized stripping devices for the hoisting of stripping devices of different weights.

[0052] Step 3: Press down and cut;

[0053] The hoisting mechanism drives the device for stripping grassland in sandy loam substrate soil in high-altitude and cold regions, which was assembled in step two, to press down, so that the cutting mechanism 3 cuts into the soil to a certain depth, which can be selected according to the thickness of the grassland to be stripped, so that the cutting section of the stripping blade 41 stored in the storage track 141 is in contact with the grassland; so that the stripping blade 41 can be moved from the storage track 141 to the sliding track 142 to cut the grassland.

[0054] Step 4: Remove the grass and spray soil stabilizer;

[0055] Turn on the dual-output shaft motor 421 and set its rotation direction to forward. Retract the horizontal pull steel cable 422 and release the pullback steel cable 423. The stripping blade 41 moves along the sliding track 142 toward the dual-output shaft motor 421. The tip of the cutting section cuts into the soil. Under the traction of the horizontal pull steel cable 422, it cuts the grass roots and soil located in the soil, causing the transport section 412 to separate the cut grass from the original soil. During the cutting process, control the spraying mechanism 2 to spray soil stabilizer onto the stripped grass below. Figure 4As shown, the dual-output shaft motor 421 rotates forward, the horizontal pull steel cable 422 is retracted, and the pullback steel cable 423 is released, driving the entire stripping blade 41 to move from the storage track 141 to the sliding track 142. Since the sliding track 142 has been cut into the soil along with the cutting mechanism 3, when the stripping blade 41 moves along the sliding track 142, the tip of the cutting section of the stripping blade 41 cuts into the soil, cutting the grass roots and soil in the soil, so that the grass enclosed by the frame 1 is completely stripped out by the stripping mechanism 4. At the same time as stripping the grass, in order to avoid the looseness of the sandy loam substrate soil from affecting the stripping process, the spraying mechanism 2 located above the frame 1 begins to spray soil stabilizer onto the grass inside the frame 1, temporarily stabilizing the turf and soil and increasing soil nutrients, so that the integrity of the grass stripping and the survival rate of the re-laid turf can be effectively guaranteed.

[0056] Step 5: Stripping complete; transport the stripped turf.

[0057] When the stripping blade 41 moves to cover the bottom of the entire frame 1, the grass stripping is complete. The hoisting mechanism moves the hoisting rope 13 upward, and the hoisting rope 13 moves the entire device for stripping grass in sandy loam substrate soil in high-altitude and cold regions upward through the pressure connecting rod 414, leaving the stripping area. When the stripping blade 41 is pulled out from the storage track 141 by the horizontal pull steel rope 422 and moves towards the dual output shaft motor 421 located on the opposite side of the storage track 141 until the stripping blade 41 covers the bottom of the entire frame 1, the grass stripping is complete, and the dual output shaft motor 421 stops running. At this time, the stripping blade 41 covers the bottom of the entire frame 1, so that the stripped grass is always located on the top of the stripping blade 41 and surrounded by the frame 1, so as to avoid damage to the integrity of the stripped grass due to mechanical vibration or external wind during the transfer process. At the same time, the hoisting mechanism is restarted to lift the entire device for stripping grass in sandy loam substrate soil in high-altitude and cold regions away from the stripping and re-laying area 52 and transfer it to the place for storing the stripped grass, and then the operator unloads it.

[0058] The method described above for stripping sandy loam substrate grassland in high-altitude and cold regions effectively ensures the integrity of the stripped grassland and achieves high stripping efficiency. By adding targeted components suitable for sandy loam substrate grassland, namely a frame frame 1 and a tracked stripping blade 41 that covers the entire bottom of the frame 1, and in conjunction with the cutting mechanism 3 located at the bottom of the frame 1, the device for stripping sandy loam substrate grassland in high-altitude and cold regions can easily insert and cut the soil. The tracked stripping blade 41 completely covers the bottom of the frame 1, effectively ensuring the integrity of the native meadow turf and soil. Furthermore, the device can be hoisted using an existing hoisting mechanism to improve the grassland stripping efficiency. During the cutting process, the spraying mechanism 2 sprays a soil stabilizer onto the stripped grassland located inside the frame 1 to solidify the sandy loam substrate grassland, preventing any impact on the integrity of the grassland during transportation or stripping. Additionally, nutrient solution can be added to the existing soil stabilizer to improve soil nutrients and increase the survival rate of subsequent grassland re-laying.

[0059] To improve the efficiency of turf stripping and ensure the integrity of turf stripping, such as Figure 8 As shown, the equipment assembly in step two includes multiple devices arranged in rows for stripping sandy loam substrate grassland in high-altitude and cold regions, with adjacent frames 1 connected by connectors 15 to form an integrated structure. Figure 1 , Figure 8 As shown, the frame 1 in the above-mentioned device for stripping grass in sandy loam substrate soil in high-altitude cold regions can be assembled to achieve the stripping and transportation of multiple turf at one time. Specifically, the first connecting block 151 and the second connecting block 152, which are respectively set between two adjacent frames 1, are connected by bolts that pass through the first threaded hole 1511 and the second threaded hole 1521 in sequence. As needed to strip the grass to the required size, they can be spliced ​​and disassembled to achieve the stripping of multiple turf at one time, improve the stripping efficiency of the grass and ensure the integrity of the stripping.

[0060] After the transfer is completed, the stripped grass needs to be unloaded, specifically, as follows: Figure 5As shown, the dual-output shaft motor 421 is turned on, and its rotation direction is reversed. The pull-back steel cable 423 is retracted, and the horizontal pull steel cable 422 is released. The stripping blade 41 is pulled out from the end away from the dual-output shaft motor 421, and the stripped grass is unloaded from the side of the stripping blade 41 closest to the dual-output shaft motor 421. By reversing the dual-output shaft motor 421, the pull-back steel cable 423 and the horizontal pull steel cable 422, which are wound in opposite directions, begin to be retracted and released. The horizontal pull steel cable is retracted, and the horizontal pull steel cable 422 is released, so that the entire stripping blade 41 begins to be pulled away from the side away from the dual-output shaft motor 421. This creates a gap between the stripping blade 41 and the dual-output shaft motor 421, allowing the stripped grass to be slowly unloaded from the device for stripping sandy loam substrate grass in high-altitude cold regions without damaging the integrity of the stripped grass.

[0061] To facilitate the storage of the undiluted sandy loam substrate turf before it solidifies, a mulch film needs to be laid at the unloading site before unloading the turf in step six. Specifically, before loading the turf onto the truck, a mulch film is placed under the truck bed or at the designated placement location to facilitate the storage of the sandy loam substrate turf before the soil solidifies. After the first layer of turf is placed, a mulch film is laid at the location where the second layer of turf is stacked, and so on, before each subsequent layer of turf is stacked, to ensure the soil of the native turf is solidified and maintains its aesthetic appeal. The aforementioned mulch film device can be a common roller-type mulch film device. To protect the ecological environment, a green and environmentally friendly biodegradable film can be used. If ordinary mulch film is used, it must be promptly recycled after the turf is transplanted to avoid damaging the ecological environment.
