Description

Technical Field

[0001] This invention relates to the field of soil sampler technology, specifically to a high-efficiency sampler for difficult-to-sample soils and its usage method. Background Technology

[0002] Soil samplers are tools or devices used to collect soil samples. They can be used in various soil surveys, research, analysis, and monitoring activities to identify the proportions of different particle sizes in the soil, such as sand, silt, loam, and clay. Collecting soil samples is crucial for analyzing soil moisture retention capacity, aeration, fertility, and suitability for plant growth.

[0003] Patent publication number CN207556899U discloses a high-efficiency soil sampler, including a tube body. A push rod is mounted at the top of the tube body, with a scale on its surface. A pressure block is mounted at the bottom of the push rod, a motor is mounted at the bottom of the pressure block, a connecting plate is mounted at the bottom of the motor, a fixing plate is mounted at the bottom of the connecting plate, and a sampling chamber is mounted at the bottom of the fixing plate. Hydraulic rods are mounted on both sides of the sampling chamber, and a breaking blade is mounted at the bottom of each hydraulic rod. This patent design, by incorporating the breaking blade, allows the sampling chamber to continue descending when encountering large stones that prevent it from descending. After a period of use, the breaking blade can be removed from the hydraulic rod by unscrewing the screw inside the threaded tube for replacement. This design makes the sampler easier to operate, improves sampling accuracy, and facilitates blade replacement, thus increasing the sampler's efficiency.

[0004] However, current high-efficiency soil samplers have the following problems: when drilling holes in the land, the uneven ground can easily cause the drill tube to tilt, making it difficult to collect soil from the ground. Therefore, it is necessary to design a high-efficiency sampler for soils that are difficult to sample. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency sampler for difficult-to-sample soil, in order to solve the problem mentioned in the background art, where the uneven ground surface can easily cause the drill tube to tilt, making it difficult to collect soil from the ground, thus making it difficult for the sampler to collect soil.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-efficiency sampler for difficult-to-sample soil, comprising a trolley, two U-shaped arc slide plates, a circular shell, a motor, and a drill barrel. The two U-shaped arc slide plates are respectively fixedly installed on the top surface of the trolley. The circular shell is slidably installed between the inner walls of the two U-shaped arc slide plates. The motor is fixed on the top surface inside the circular shell. The drill barrel is fixed on the bottom surface of the motor shaft. The device further comprises a shovel, a support, an anti-cracking device, and a cleaning device. The shovel is located on the left side of the trolley. The support is located on the left and right sides of the circular shell. The anti-cracking devices are located on the left and right sides of the support. The cleaning device is located on the top surface of the shovel.

[0007] The shovel device includes a horizontal plate, an arc-shaped shovel plate, and a flat pressing component. The horizontal plate is fixedly installed on the left side of the trolley, the arc-shaped shovel plate is fixed on the left side of the bottom surface of the horizontal plate, and the flat pressing component is located between the front and back of the horizontal plate. The arc-shaped shovel plate on the horizontal plate removes the uneven soil from the ground, making the ground flat.

[0008] According to the above technical solution, the flat pressing assembly includes two vertical plates, a rotating rod, and a rolling roller. The two vertical plates are respectively fixed in the middle of the front and back of the horizontal plate. The rotating rod is installed through and rotatably between the two vertical plates. The rolling roller is fixed on the outer wall of the rotating rod to prevent the rotating drill from tilting due to uneven ground, thereby avoiding the problem of soil collection difficulties for the soil collector.

[0009] According to the above technical solution, the bottom surface of the trolley is equipped with two sets of rollers, the right side of the trolley is fixedly equipped with a handle, the top surface of the trolley has four round holes, the bottom surface of the trolley is equipped with a protective cylinder, the outer wall of the drill cylinder is fixed with a spiral rotating blade, the bottom of the drill cylinder is provided with a soil return port, the drill cylinder is rotatably installed in the protective cylinder of the trolley, and the bottom surface of the arc shovel plate is chamfered.

[0010] According to the above technical solution, the support device includes two connecting plates, two telescopic rods, and a positioning component. The two connecting plates are respectively fixed in the middle of the left and right sides of the circular shell. The two telescopic rods are respectively hinged to the opposite sides of the two connecting plates. The ends of the two telescopic rods away from the two connecting plates are respectively hinged to the top surface of the trolley. The positioning component is set in the middle of the top surface of the circular shell to prevent the drill barrel on the motor shaft from shifting.

[0011] According to the above technical solution, the positioning component includes a cylinder, a cross plate, four cylinders, and four pressure rods. The cylinder is fixed in the middle of the top surface of the cylindrical shell, the cross plate is fixed in the middle of the top surface of the cylinder, the four cylinders are respectively fixed to the bottom edge of the cross plate, and the four pressure rods are slidably installed inside the four cylinders. Springs are fixed between the top surface of the four pressure rods and the top of the four cylinders. The four pressure rods are slidably installed in the four circular holes of the trolley to prevent the drilling barrel from vibrating due to the forward rotation of the motor shaft, which would cause the drilling barrel to deviate from its sampling position, thereby avoiding the problem of inaccurate sampling orientation of the soil sampler.

[0012] According to the above technical solution, the top surfaces of the telescopic ends of the two telescopic rods are fixed with hinge plates, the bottom surfaces of the two telescopic rods are respectively fixed with hinge plates, and the bottom surfaces of the four pressure rods are respectively fixed with circular rubber pads.

[0013] According to the above technical solution, the anti-cracking device includes two L-shaped plates, two T-shaped pressure plates, two U-shaped plates, and a buffer assembly. The two L-shaped plates are respectively fixed to the bottom of the front and back of the cylinder. The two T-shaped pressure plates are respectively fixed to the ends of the two L-shaped plates away from the cylinder.

Two of the pads are fixed in the middle of the bottom surface of two L-shaped plates, and the other two pads are fixed on the top surface of the trolley. The two spring plates are fixed between the four pads. The two spring plates are respectively set on the front and back of the two U-shaped arc slide plates to prevent the soil collector from generating excessive vibration when collecting soil, which would cause uneven drilling force in the drill barrel, thereby avoiding the problem of equipment damage caused by excessive amplitude when the soil collector collects soil.

[0015] According to the above technical solution, the cleaning device includes a water tank, a water pump, two water pipes, an electric spray nozzle, and a protective component.

The electric spray nozzle is fixedly installed at the end of the two water pipes away from the water pump, and the electric spray nozzle is located at the gap between the two U-shaped arc sliding plates. The protective component is located on the left side of the water tank. The electric spray nozzle sprays water from the water pipes, and the sprayed water flows to clean the drill barrel, preventing a large amount of sludge from adhering to the drill barrel.

[0016] According to the above technical solution, the protective component includes a baffle and two inclined plates. The baffle is fixedly installed on the left side of the water tank, and the two inclined plates are respectively fixed on the front and back of the baffle. The baffle protects the equipment from being blocked by foreign objects during movement. The baffle drives the inclined plates to move forward, preventing branches of bushes from slipping onto the equipment, thereby avoiding the problem of damage to the soil collector during movement.

[0017] A method for using a high-efficiency sampler for difficult-to-sample soil includes the following steps:

[0018] S1. Staff members push the cart using the handles on it;

[0019] S2. The trolley moves the horizontal plate forward, and the arc-shaped shovel on the horizontal plate removes the uneven soil on the ground. The horizontal plate moves the vertical plate forward, and the vertical plate moves the rotating rod forward. The roller on the rotating rod is subjected to the friction of the ground, and the roller rolls the uneven ground.

[0020] S3. The trolley moves the water tank and the baffle forward, and the baffle moves the inclined plate forward.

[0021] S4. The staff starts the motor in the round shell through the wire. The motor shaft starts to rotate forward. The motor drives the round shell to slide downward in the U-shaped arc slide plate. The round shell is restricted by the telescopic rod.

[0022] S5. The round shell drives the cylinder to move downward, the cylinder drives the cross plate to move downward, the cross plate drives the cylinder to move downward, the cylinder drives the pressure rod to move downward, the pressure rod slides upward in the cylinder, and under the action of the spring force of the pressure rod, the pressure rod tightly presses the ground.

[0023] S6. The cylinder drives the L-shaped plate to move downward, the L-shaped plate drives the T-shaped pressure plate to move downward, the T-shaped pressure plate slides downward in the U-shaped plate, and the T-shaped pressure plate inserts downward into the soil.

[0024] S7. The L-shaped plate moves the pad downwards, and the spring plate in the pad is compressed.

[0025] S8. The staff started the water pump in the water tank through the wire. The water pump started to draw water from the water tank and the water in the tank entered the water pipe.

[0026] S9. The staff activates the electric water nozzle via an electric wire. The electric water nozzle sprays water from the water pipe, and the sprayed water cleans the drill barrel.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0028] (1) The present invention, through the setting of the shovel device, enables the horizontal plate, the arc shovel plate, the vertical plate and the rotating rod to cooperate with the rolling roller. The arc shovel plate on the horizontal plate removes the uneven soil on the ground, making the ground flat, and the rolling roller on the rod rolls the uneven ground, preventing the uneven ground from causing the rotating drill cylinder to tilt, thereby avoiding the problem of soil collectors having difficulty collecting soil.

[0029] (2) The present invention, through the setting of the support device, makes the connecting plate, telescopic rod, cylinder, cross plate and cylinder cooperate with the pressure rod. The telescopic rod prevents the position of the motor in the shell from shifting during the downward movement, and prevents the drill tube on the motor shaft from shifting. When the pressure rod moves downward to the ground, the pressure rod slides upward in the cylinder. Under the action of the spring force of the pressure rod, the pressure rod tightly presses the ground, preventing the drill tube from being offset due to the vibration caused by the forward rotation of the motor shaft, thereby avoiding the problem of inaccurate sampling position of the soil sampler.

[0030] (3) The present invention, through the setting of the anti-cracking device, makes the L-shaped plate, T-shaped pressure plate, U-shaped plate and pad plate cooperate with the spring plate. The T-shaped pressure plate is inserted downward into the soil. The soil is restricted by the T-shaped pressure plate, preventing the soil from cracking and causing collection failure when the drill barrel moves downward. In addition, the spring plate in the pad plate is squeezed. Under the elastic force of the spring plate, the pad plate on the spring plate buffers the L-shaped plate. The L-shaped plate reduces the vibration generated by the soil collector when collecting soil, and prevents the soil collector from generating too much vibration when collecting soil, which causes uneven drilling force of the drill barrel. Thus, the problem of equipment damage caused by excessive amplitude when the soil collector collects soil is avoided.

[0031] (4) The present invention, through the setting of the cleaning device, makes the water tank, water pump, water pipe, electric water nozzle and baffle cooperate with the inclined plate. The electric water nozzle sprays water from the water pipe, and the sprayed water flows to clean the drill barrel, preventing a large amount of sludge from adhering to the drill barrel. In addition, the baffle protects the equipment from being blocked by foreign objects during the movement. The baffle drives the inclined plate to move forward, preventing the branches of the bushes from slipping on the equipment, thereby avoiding the problem of the soil collector being damaged during the movement.

[0041] 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. Example

[0042] Please see Figure 1-5This invention provides a technical solution: a high-efficiency sampler for difficult-to-sample soil, comprising a cart 1, two U-shaped arc slide plates 2, a circular shell 3, a motor 4, and a drill barrel 5. The two U-shaped arc slide plates 2 are respectively fixedly installed on the top surface of the cart 1, the circular shell 3 is slidably installed between the inner walls of the two U-shaped arc slide plates 2, the motor 4 is fixed to the top surface inside the circular shell 3, and the drill barrel 5 is fixed to the bottom surface of the motor 4's rotating shaft. It also includes a shovel device 6 and supporting devices 7, wherein the shovel device 6 is located on the left side of the cart 1. The shoveling device 6 includes a horizontal plate 61, an arc-shaped shovel plate 62, and a flattening assembly 600. The horizontal plate 61 is fixedly installed on the left side of the trolley 1, and the arc-shaped shovel plate 62 is fixed on the left side of the bottom surface of the horizontal plate 61. The trolley 1 drives the horizontal plate 61 to move forward, and the horizontal plate 61 drives the arc-shaped shovel plate 62 to move forward. The arc-shaped shovel plate 62 removes uneven soil from the ground, making the ground level. The flattening assembly 600 is located between the front and back of the horizontal plate 61. The flattening assembly 600 includes two vertical plates 63, a rotating rod 64, and a rolling roller 6. 5. Two vertical plates 63 are fixed to the middle of the front and back of the horizontal plate 61, respectively. A rotating rod 64 is installed through and rotatably between the two vertical plates 63. A rolling roller 65 is fixed to the outer wall of the rotating rod 64. The horizontal plate 61 drives the vertical plates 63 to move forward, the vertical plates 63 drive the rotating rod 64 to move forward, and the rotating rod 64 drives the rolling roller 65 to move forward. The rolling roller 65 on the rotating rod 64 is subjected to the friction of the ground, and the rolling roller 65 begins to rotate. The rolling roller 65 drives the rotating rod 64 to rotate, and the rolling roller 65... 5. Rolling the uneven ground prevents the drill cylinder 5 from tilting due to unevenness, thus avoiding the problem of soil collection difficulty for the soil collector. Two sets of rollers are installed on the bottom of the cart 1. A handle is fixedly installed on the right side of the cart 1. Four round holes are opened on the top surface of the cart 1. A protective cylinder is installed in the middle of the bottom surface of the cart 1. A spiral rotating blade is fixed on the outer wall of the drill cylinder 5. A soil return port is set at the bottom of the drill cylinder 5. The drill cylinder 5 is rotatably installed in the protective cylinder of the cart 1. The bottom surface of the arc shovel plate 62 is chamfered.

[0043] Support devices 7 are respectively installed on the left and right sides of the circular shell 3. Each support device 7 includes two connecting plates 71, two telescopic rods 72, and a positioning assembly 700. The two connecting plates 71 are fixed to the middle of the left and right sides of the circular shell 3, respectively. The two telescopic rods 72 are respectively hinged to the opposite sides of the two connecting plates 71. The ends of the two telescopic rods 72 away from the two connecting plates 71 are respectively hinged to the top surface of the trolley 1. The motor 4's shaft drives the drill barrel 5 to rotate clockwise. The spiral vanes on the drill barrel 5 rotate into the soil, and the spiral vanes drive the drill barrel 5 to move downwards into the soil. The drill barrel 5 drives the motor 4 to move downwards, and the motor 4 drives the circular shell 3 to rotate clockwise. Shell 3 moves downwards, sliding within the U-shaped arc slide plate 2. Simultaneously, shell 3 drives connecting plate 71 downwards, which in turn drives telescopic rod 72 downwards. Telescopic rod 72 is constrained by connecting plate 71 and rotates within it. Conversely, telescopic rod 72 is also constrained by trolley 1 and rotates on trolley 1. The telescopic end of telescopic rod 72 begins to retract. The constraint of telescopic rod 72 on shell 3 prevents the position of motor 4 within shell 3 from shifting during downward movement, thus preventing displacement of the drill barrel 5 on the motor 4's shaft.

[0044] The positioning component 700 is located in the center of the top surface of the circular shell 3. The positioning component 700 includes a cylinder 73, a cross plate 74, four cylinders 75, and four pressure rods 76. The cylinder 73 is fixed in the center of the top surface of the circular shell 3, the cross plate 74 is fixed in the center of the top surface of the cylinder 73, the four cylinders 75 are respectively fixed to the bottom edge of the cross plate 74, and the four pressure rods 76 are slidably installed inside the four cylinders 75. Springs are fixed between the top surface of the four pressure rods 76 and the top of the four cylinders 75. The four pressure rods 76 are slidably installed in the four circular holes of the trolley 1. The circular shell 3 drives the cylinder 73 to move downwards, and the cylinder 73 drives the cross plate 74 to move downwards. Plate 74 drives cylinder 75 to move downward, cylinder 75 drives pressure rod 76 to move downward, pressure rod 76 moves downward and passes through the circular hole of trolley 1. When pressure rod 76 moves downward to the ground, pressure rod 76 slides upward in cylinder 75, and under the action of spring force, pressure rod 76 tightly presses the ground to prevent the drilling cylinder 5 from being offset due to the vibration caused by the forward rotation of motor 4 shaft, thus avoiding the problem of inaccurate sampling orientation of soil sampler. The top surface of the telescopic ends of the two telescopic rods 72 is fixed with hinge plates, the bottom surface of the two telescopic rods 72 is fixed with hinge plates respectively, and the bottom surface of the four pressure rods 76 is fixed with circular rubber pads respectively.

[0045] In use, the staff pushes the cart 1 with the handle on the cart 1. The cart 1 moves forward, which in turn moves the U-shaped arc slide plate 2 forward. The U-shaped arc slide plate 2 moves the round shell 3 forward, which in turn moves the motor 4 forward. The motor 4 rotates the drill cylinder 5 forward. The protective sleeve of the cart 1 prevents the drill cylinder 5 from being damaged during the movement. The cart 1 moves the horizontal plate 61 forward, which in turn moves the arc shovel plate 62 forward. The arc shovel plate 62 removes uneven soil from the ground, making the ground level. At the same time, the horizontal plate 61 moves the vertical plate 63 forward, which in turn moves the rotating rod 64 forward. The rotating rod 64 moves the rolling roller 65 forward. The rolling roller 65 on the rotating rod 64 is subjected to the friction of the ground, and the rolling roller 65 starts to rotate. The rolling roller 65 drives the rotating rod 64 to rotate, so that the rolling roller 65 rolls the uneven ground, preventing the drill cylinder 5 from tilting due to uneven ground, thus avoiding the problem of the soil collector having difficulty collecting soil.

[0046] Once the location for soil collection is determined, the staff activates the motor 4 inside the cylindrical shell 3 via an electrical wire. The motor 4 shaft rotates clockwise, driving the drill barrel 5 to rotate clockwise. The spiral vanes on the drill barrel 5 enter the soil and move the drill barrel 5 downwards. The drill barrel 5 then moves the motor 4 downwards, which in turn moves the cylindrical shell 3 downwards. The cylindrical shell 3 slides downwards within the U-shaped arc slide plate 2, simultaneously causing the connecting plate 71 to move downwards. The connecting plate 71 then moves the telescopic rod 72 downwards. The telescopic rod 72 is restricted by the connecting plate 71 and rotates within it. The telescopic rod 72 is also restricted by the trolley 1 and rotates on the trolley 1. The telescopic end of the telescopic rod 72 begins to retract, and the cylindrical shell 3 is subjected to... The telescopic rod 72 restricts the position of the motor 4 in the circular shell 3 during its downward movement, preventing the drill barrel 5 on the motor 4 shaft from shifting. Simultaneously, the circular shell 3 drives the cylinder 73 downward, which in turn drives the cross plate 74 downward, which in turn drives the cylinder 75 downward. The cylinder 75 then drives the pressure rod 76 downward, passing through the circular hole of the trolley 1. When the pressure rod 76 reaches the ground, it slides upward within the cylinder 75. Under the spring force of the pressure rod 76, it tightly presses against the ground, preventing the drill barrel 5 from shifting due to vibrations caused by the forward rotation of the motor 4 shaft. This avoids the problem of inaccurate sampling orientation of the soil sampler. Example

[0047] Please see Figure 1-7Based on Embodiment 1, this embodiment also includes an anti-cracking device 8 and a cleaning device 9. The anti-cracking device 8 is respectively installed on the left and right sides of the support device 7. The anti-cracking device 8 includes two L-shaped plates 81, two T-shaped pressure plates 82, two U-shaped plates 83, and a buffer assembly 800. The two L-shaped plates 81 are respectively fixed to the bottom of the front and back of the cylinder 73. The two T-shaped pressure plates 82 are respectively fixed to the ends of the two L-shaped plates 81 away from the cylinder 73. The two U-shaped plates 83 are respectively fixed to the middle of the front and back of the trolley 1. The two T-shaped pressure plates 82 are respectively slidably installed on the inner walls of the two U-shaped plates 83. The cylinder 73 drives the L-shaped plates 81 to move downward, and the L-shaped plates 81 drive the T-shaped pressure plates 82 to move downward. The T-shaped pressure plates 82 slide downward in the U-shaped plates 83. The T-shaped pressure plates 82 are inserted downward into the soil. The soil is restricted by the T-shaped pressure plates 82 to prevent the soil from cracking when the drill barrel 5 drills downward. The crack caused the soil collection to fail. The buffer assembly 800 is set in the middle of the bottom surface of the two L-shaped plates 81. The buffer assembly 800 includes four pads 84 and two spring plates 85. The two pads 84 are fixed in the middle of the bottom surface of the two L-shaped plates 81 respectively. The other two pads 84 are fixed on the top surface of the trolley 1 respectively. The two spring plates 85 are fixed between the four pads 84 respectively. The two spring plates 85 are set on the front and back of the two U-shaped arc slide plates 2 respectively. The L-shaped plate 81 drives the pads 84 to move downward. The spring plates 85 in the pads 84 are squeezed. Under the elastic force of the spring plates 85, the pads 84 on the spring plates 85 buffer the L-shaped plate 81. The L-shaped plate 81 reduces the vibration generated by the soil collector when collecting soil and prevents the soil collector from generating too much vibration when collecting soil, which will cause uneven drilling force of the drill barrel 5. This avoids the problem of equipment damage caused by excessive amplitude when the soil collector collects soil.

[0048] The cleaning device 9 is installed on top of the removal device 6. The cleaning device 9 includes a water tank 91, a water pump 92, two water pipes 93, an electric spray nozzle 94, and a protective assembly 900. The water tank 91 is fixedly installed on the top surface of the horizontal plate 61. The water pump 92 is fixedly installed inside the bottom of the water tank 91. The two water pipes 93 are respectively fixedly installed to the right of the water pump 92, passing through and fixedly installed on the bottom right side of the inner wall of the water tank 91. The electric spray nozzle 94 is fixedly installed at the end of the two water pipes 93 away from the water pump 92, and is located in the gap between the two U-shaped arc sliding plates 2. The water pump 92 begins to draw water from the water tank 91, and the water in the water tank 91 enters the water pipes 93. Simultaneously, the operator activates the device via an electric wire. An electric water nozzle 94 sprays water from the water pipe 93 to clean the drill barrel 5, preventing a large amount of sludge from adhering to it. A protective component 900 is located on the left side of the water tank 91. The protective component 900 includes a baffle 95 and two inclined plates 96. The baffle 95 is fixedly installed on the left side of the water tank 91, and the two inclined plates 96 are fixed to the front and back of the baffle 95, respectively. A horizontal plate 61 moves the water tank 91 forward, which in turn moves the baffle 95 forward. The baffle 95 protects the equipment from obstruction by foreign objects during movement. The baffle 95 moves the inclined plates 96 forward to prevent branches from shrubs from slipping onto the equipment, thus avoiding damage to the soil collector during movement.

[0049] As the cylindrical shell 3 moves the cylinder 73 downwards, the cylinder 73 moves the L-shaped plate 81 downwards, which in turn moves the T-shaped pressure plate 82 downwards. The T-shaped pressure plate 82 slides downwards within the U-shaped plate 83 and inserts into the soil. The soil is restricted by the T-shaped pressure plate 82, preventing soil cracking and collection failure when the drill cylinder 5 drills downwards. Simultaneously, the L-shaped plate 81 moves the pad 84 downwards, compressing the spring plate 85 within it. Under the elastic force of the spring plate 85, the pad 84 on the spring plate 85 buffers the L-shaped plate 81. The L-shaped plate 81 reduces the vibration generated by the soil collector during soil collection, preventing excessive vibration from causing uneven drilling force in the drill cylinder 5. This avoids the problem of equipment damage caused by excessive amplitude during soil collection.

[0050] Upon completion of the data collection, the staff activates the motor 4 inside the cylindrical shell 3 via an electrical wire. The motor 4 shaft reverses, causing the drill barrel 5 to reset. Simultaneously, the staff activates the water pump 92 in the water tank 91 via an electrical wire. The water pump 92 draws water from the water tank 91, which then flows into the water pipe 93. At the same time, the staff activates the electric water nozzle 94 via an electrical wire. The electric water nozzle 94 sprays water from the water pipe 93, and the sprayed water cleanses the drill barrel 5, preventing a large amount of sludge from adhering to it. As the trolley 1 moves forward, the horizontal plate 61 moves the water tank 91 forward, which in turn moves the baffle 95 forward. The baffle 95 protects the equipment from obstruction during movement. The baffle 95 also moves the inclined plate 96 forward, preventing branches from the bushes from slipping onto the equipment, thus avoiding damage to the soil collector during movement. Example

[0051] A method for using a high-efficiency sampler for difficult-to-sample soil includes the following steps:

[0052] S1. The staff pushes the cart 1 using the handle on the cart 1;

[0053] S2. The trolley 1 moves the horizontal plate 61 forward, and the arc shovel plate 62 on the horizontal plate 61 removes the uneven soil on the ground. The horizontal plate 61 moves the vertical plate 63 forward, and the vertical plate 63 moves the rotating rod 64 forward.
