Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and particularly to a soil inspection sampling device for territorial space planning and its usage method. Background Art

[0002] In territorial space planning work, carrying out use layout and subdivision management for soil is a major task. And the cornerstone of this planning work is inseparable from the detection of soil quality. Through detection, reasonable planning can be carried out according to different soil qualities to achieve the optimal and efficient planning space. Soil detection usually involves regularly extracting soil samples from the site, and then conducting specific evaluations through detailed sample preparation, equipment analysis, data statistics, quality evaluation, etc.

[0003] In the prior art, there are still the following deficiencies in the soil sampling process:

[0004] 1. When collecting soil samples, plants and gravel on the land are often collected simultaneously. These collected plants and gravel need to be screened additionally, which increases the burden of soil collection work and affects the efficiency of subsequent soil detection.

[0005] 2. In addition, during soil detection, staff need to separately sort the soil to select soil with a smaller particle size for detection. This undoubtedly increases the steps of soil detection and reduces the detection efficiency;

[0006] In view of the above problems, the present invention document proposes a soil inspection sampling device for territorial space planning and its usage method. Summary of the Invention

[0007] The purpose of the present invention is to solve the drawbacks that plants and gravel on the existing land are collected simultaneously, and it is necessary for staff to separately select soil with a smaller particle size, and to propose a soil inspection sampling device for territorial space planning and its usage method.

[0008] To achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A soil inspection sampling device for territorial space planning, including a moving platform, a moving plate is arranged above the moving platform, a driving motor is fixed on the top of the moving plate, an output shaft of the driving motor rotates through the moving plate and is fixed with a sampling cylinder for collecting soil, a round hole is arranged on the top of the moving platform for making way for the sampling cylinder, and a collection groove for placing soil is arranged on the top of the moving platform;

[0010] It further includes a collection box slidably arranged on the top of the mobile station, and the collection box is located below the sampling cylinder for collecting the soil collected by the sampling cylinder. There is a connecting rod rotatably connected between the top of the collection box and the bottom of the moving plate, and the moving plate drives the collection box to move through the connecting rod;

[0011] It further includes a rectangular groove which is arranged at the bottom of the mobile station and communicated with the round hole. Two lead screws are rotatably connected in the rectangular groove, and the threads of the two lead screws are opposite. A U-shaped frame is arranged in the rectangular groove, and a rotating cylinder is arranged in the U-shaped frame. The two lead screws are used to drive the rotating cylinder to move and remove plant debris on the ground;

[0012] A sampling structure is arranged on the top of the mobile station for driving the sampling cylinder to take soil samples;

[0013] A vibrating and loosening structure is arranged in the collection box for vibrating and loosening the caked soil in the collection box during the process of the moving plate driving the collection box to move;

[0014] Two groups of adjustment structures are both arranged in the rectangular groove for making the U-shaped frame vertically arranged to facilitate the rotating cylinder to remove plant debris on the ground;

[0015] Two groups of transmission structures are arranged between the mobile station and the collection box for driving the lead screws to rotate during the movement of the collection box.

[0016] In a possible design, the sampling structure includes a vertical rod fixed on the top of the mobile station. A lead screw is rotatably connected to the top of the mobile station. The top of the vertical rod is fixed with a top plate, and the top of the lead screw is rotatably connected to the bottom of the top plate. The moving plate is threadedly sleeved on the outer wall of the lead screw. The top of the vertical rod slidably penetrates through the moving plate. The cooperation between the lead screw and the moving plate is used to drive the sampling cylinder to lift and lower. A push rod is fixed on the inner wall of the top of the sampling cylinder. The output shaft of the push rod is fixed with a push plate, and the push plate is slidably arranged in the sampling cylinder. The push rod pushes the collected soil downward into the collection box through the sampling cylinder; The lead screw is driven to rotate by a motor. The lead screw drives the sampling cylinder to penetrate through the round hole and insert into the soil through the moving plate for soil collection. At the same time, the motor is driven to drive the sampling cylinder to rotate to enable the sampling cylinder to smoothly insert into the soil. When the sampling cylinder completes soil collection, the sampling cylinder resets upward. At the same time, the U-shaped frame, the rotating cylinder and the collection box reset synchronously. When the sampling cylinder moves above the collection box, the output shaft of the push rod pushes the push plate to move downward to discharge the soil in the sampling cylinder into the collection box.

[0017] In a possible design, the vibrating and dispersing structure includes a sieve plate fixed inside the collection box. The sieve plate is used for screening soil with small particle sizes. One side of the bottom of the collection box is provided with a discharge port, and the discharge port is matched with the collection tank. A rotating shaft rotatably penetrates through the collection box. A plurality of cams are fixedly sleeved on the outer wall of the rotating shaft, and the cams are used for knocking the sieve plate. Both ends of the rotating shaft respectively rotatably extend to both sides of the collection box and are both fixed with first gears. Two first racks are fixed on the top of the moving table, and the first gears are meshed with the first racks. The cooperation between the first gears and the first racks is used to drive the rotating shaft and the cams to rotate. When the moving plate drives the sampling cylinder to move downward, the moving plate pushes the collection box to move to one side through the connecting rod, and the collection box disengages from below the sampling cylinder, avoiding the collection box from obstructing the movement of the sampling cylinder. Additionally, when the collection box moves, the rotating shaft and the cams are driven to rotate through the cooperation between the first gears and the first racks. The cams are used for knocking the sieve plate to disperse the caked soil on the sieve plate and screen the soil with small particle sizes. The inclined panel guides the soil and discharges it into the collection tank through the discharge port.

[0018] In a possible design, the adjustment structure includes a moving block slidably arranged on the inner wall of the top of the rectangular groove. The moving block is threadedly connected with the lead screw. A round shaft rotatably penetrates through the moving block. A U-shaped seat is fixedly sleeved on the outer wall of the round shaft. One end of the round shaft penetrates through the U-shaped seat and is fixed with a third gear. A third rack is fixed on the inner wall of one side of the rectangular groove, and the third rack is meshed with the third gear for driving the U-shaped seat to rotate. A round rod is fixed on one side of the U-shaped seat. One end of the round rod slidably extends into the U-shaped frame. A spring fixedly connected with the U-shaped seat is sleeved on the outer wall of the round rod. One end of the spring is fixedly connected with one side of the second gear. A plurality of conical nails are fixed on the outer wall of the rotating cylinder. The lead screw drives the moving block to move to the right. The moving block synchronously drives the round shaft to move. The round shaft drives the U-shaped seat to rotate counterclockwise by 90° under the action of the third rack and the third gear, so that the U-shaped frame can be placed vertically. And the U-shaped frame moves downward under the action of the spring until the rotating cylinder is close to the ground. Then the rotating cylinder is driven to rotate by the motor. Therefore, when the lead screw drives the moving block to move, the rotating cylinder can remove the gravel and plants on the ground to be sampled by the sampling cylinder. When the bottom end of the sampling cylinder penetrates through the round hole, the rotating cylinder just moves away from the round hole, avoiding the rotating cylinder from obstructing the sampling cylinder, so that the sampling cylinder can smoothly collect the soil and avoid the soil sample from being mixed with plants and gravel.

[0019] In a possible design, the transmission structure includes a relief groove provided at the top of the moving platform. A second rack is slidably connected in the relief groove, and the top of the second rack is fixedly connected to the bottom of the collection box. The bottom inner wall of the relief groove is rotatably connected to a drive shaft. A second gear meshing with the second rack is fixed to the top end of the drive shaft. The bottom end of the drive shaft rotatably extends into the rectangular groove and is fixed with a first bevel gear. A second bevel gear meshing with the first bevel gear is fixedly sleeved on the outer wall of the lead screw. When the collection box moves outward, the cooperation between the second rack and the second gear drives the drive shaft and the first bevel gear to rotate. The cooperation between the first bevel gear and the second bevel gear drives the lead screw to rotate, and the lead screw drives the moving block to move to the right, thereby being able to drive the adjustment structure to operate.

[0020] In a possible design, a damping bearing is fixed inside the moving block. The round shaft passes through the damping bearing, and the damping bearing is used to prevent the round shaft from shaking. When the moving block drives the third gear to disengage from the third rack, the third gear drives the U-shaped frame to be vertically placed under the action of the third rack. After that, when the moving block continues to move, the damping bearing can prevent the U-shaped frame from rotating.

[0021] In a possible design, universal wheels are fixed at the four corners of the bottom of the moving platform for moving the moving platform to a specified position. A handrail is fixed on one side of the top of the moving platform for pushing the moving platform to move.

[0022] In a possible design, an inclined panel is fixed to the bottom inner wall of the collection box, and the inclined panel cooperates with the discharge port to guide the soil to the discharge port, facilitating the discharge of the soil.

[0023] In a possible design, a through hole is provided in the mobile station. One end of one of the lead screws rotatably extends into the through hole and is fixed with a first synchronous pulley. A second synchronous pulley is rotatably connected to one inner wall of the through hole. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt for transmission. An outlet hole communicating with the collection tank is provided on one side of the mobile station. A transmission shaft is rotatably connected in the outlet hole. One end of the transmission shaft rotatably penetrates through the collection tank and extends into the through hole. The outer wall of the transmission shaft is slidably connected with a sleeve located in the through hole through a chute and a slider. One end of the sleeve close to the second synchronous pulley is fixed with a dial rod. A plurality of dial pieces are fixed on one side of the second synchronous pulley. The dial rod and the dial pieces cooperate to drive the sleeve to rotate. A conveying roller is fixedly sleeved on the outer wall of the transmission shaft and is located in the outlet hole. The conveying roller and the outlet hole cooperate to discharge the soil in the collection tank to the outside through the outlet hole. The outer wall of the sleeve is rotatably sleeved with a push plate. The push plate is slidably arranged in the through hole, and one end of the push plate extends to one side of the mobile station for driving the sleeve to move. Guide plates are fixed on the inner walls of the two opposite sides of the collection tank for guiding the soil; when it is necessary to take out the soil sample in the collection tank, the push plate is used to push the sleeve to move to one side. The sleeve drives the dial rod to move. The dial rod just cooperates with the dial pieces. Therefore, when the lead screw drives the second synchronous pulley to rotate, the second synchronous pulley drives the transmission shaft and the conveying roller to rotate through the cooperation of the dial rod and the dial pieces for discharging the soil sample to the outside. And the conveying roller can further mix the soil samples at multiple different positions when rotating.

[0024] In this application, a method for using a soil inspection and sampling device for territorial space planning includes the following steps:

[0025] S1. The driving motor uses the lead screw and the moving plate to rotate and insert the sampling cylinder into the soil at a specified position to collect samples, and after collecting at multiple points and mixing, remove impurities for preparation for detection;

[0026] S2. When sampling, the collection frame automatically avoids, and at the same time the sieve plate vibrates to disperse the soil blocks and screen the fine soil, and guides it to the collection tank through the inclined plane to promote soil mixing;

[0027] S3. Before sampling, the U-shaped frame rotates and descends, and the rotating cylinder rotates closely against the ground to clean the gravel and plants to ensure pure sampling, and then avoids interfering with sampling;

[0028] S4. After sampling is completed, the sampling cylinder rises, and at the same time the U-shaped frame and the collection frame are reset; the soil in the sampling cylinder is discharged into the collection frame through the push plate;

[0029] S5. When needed, push the sleeve to drive the transmission shaft to rotate, mix and discharge the soil sample through the rotation of the conveying roller, realizing convenient sampling and sample processing.

[0030] Beneficial effects:

[0031] In the present invention, the moving block is in threaded connection with the lead screw. A round shaft rotatably penetrates through the moving block. A U-shaped seat is fixedly sleeved on the outer wall of the round shaft. A third gear is fixed at one end of the round shaft. A third rack is fixed on one inner wall of the rectangular groove. A round rod is fixed on one side of the U-shaped seat. One end of the round rod slidably extends into the U-shaped frame. A rotating cylinder is rotatably connected in the U-shaped frame. When the moving block moves, the U-shaped seat is driven to rotate to a vertical state through the cooperation of the round shaft with the third rack and the third gear. Then, the rotating cylinder is driven to rotate by the motor, so that the gravel and plants on the ground to be sampled by the sampling cylinder can be removed, and thus the sampling cylinder can smoothly collect soil, avoiding the inclusion of plants and gravel in the soil sample.

[0032] In the present invention, a sieve plate is fixed in the collection box. A rotating shaft rotatably penetrates through the collection box. A plurality of cams are fixedly sleeved on the outer wall of the rotating shaft. First gears are fixed at both ends of the rotating shaft. Two first racks are fixed on the top of the moving table. When the moving plate moves downward, the collection box is pushed to move to one side through the connecting rod. The rotating shaft and the cams are driven to rotate through the cooperation of the first gears and the first racks. The cams are used to knock the sieve plate to vibrate and disperse the caked soil on the sieve plate and screen the soil with small particle sizes.

[0033] In the present invention, the top of the collection box and the bottom of the moving plate are in transmission connection through a connecting rod. A driving shaft rotatably penetrates through the moving table. A second gear and a first bevel gear are respectively fixed at the top end and the bottom end of the driving shaft. The second gear meshes with a second rack fixed at the bottom of the collection box. The first bevel gear meshes with a second bevel gear fixed on the outer wall of the lead screw. Thus, when the moving plate moves downward for sampling, the vibration-dispersing structure and the adjusting structure can be sequentially driven to vibrate and screen the soil and clean the plants and gravel on the ground. The structure is simple, and only one power source is needed to complete multiple tasks.

[0034] In the present invention, through the downward movement of the moving plate, the soil can be sequentially vibrated and dispersed, the soil with small particle sizes can be screened, and the plants and gravel on the ground can be cleaned. This not only avoids the inclusion of plants and gravel in the soil sample but also can synchronously vibrate and directly screen the soil with small particle sizes. The operation is simple, greatly improving the soil collection efficiency and also improving the later soil detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] Example 1

[0049] Reference Figures 1 - 5 The sampling device is used in the field of soil sampling, and mainly includes a moving platform 1, a moving plate 5, a driving motor 6, a sampling tube 7, a collecting frame 10, a rectangular slot 20, a lead screw 21, a U-shaped frame 35, a rotating tube 36 and other components. The moving platform 1 is the basis of the entire device, and a circular hole 19 is provided on the top for the sampling tube 7 to pass through for soil sampling, and a collecting slot 38 is provided for collecting the processed soil. The moving plate 5 realizes lifting and lowering motion under the drive of the driving motor 6 through the combined structure of the vertical rod 2 and the lead screw 3, and drives the sampling tube 7 to collect soil.

[0050] Reference Figure 1 and Figure 5 The sampling structure is mainly composed of a vertical rod 2, a screw rod 3, a top plate 4, a mobile plate 5, a sampling tube 7 and an electric push rod 8. The vertical rod 2 is fixed on the mobile platform 1, the screw rod 3 is rotatably connected to the mobile platform 1 through a bearing, the top plate 4 is fixed to the top of the vertical rod 2, and the top of the screw rod 3 is rotatably connected to the top plate 4. The mobile plate 5 is sleeved on the screw rod 3 through a thread, and the vertical rod 2 passes through the mobile plate 5 to provide a guiding effect. The sampling tube 7 is fixed to the bottom of the mobile plate 5 and is driven by a driving motor 6 to achieve rotation.

[0051] Specifically, the motor drives the lead screw 3 to rotate. Due to the threaded fit between the lead screw 3 and the moving plate 5, the moving plate 5 drives the sampling cylinder 7 to move up and down along the lead screw 3. At the same time, the driving motor 6 rotates the sampling cylinder 7 to facilitate sampling by inserting it into the soil. After sampling, the sampling cylinder 7 rises and resets, and the electric push rod 8 pushes the push plate 9 to push the soil in the sampling cylinder 7 into the lower collection box 10.

[0052] Referring to Figure 4 , Figure 6 and Figure 7 , the vibrating and loosening structure mainly consists of a sieve plate 12, a rotating shaft 15, a cam 16, a first gear 17, and a first rack 18. The sieve plate 12 is fixed inside the collection box 10 and is used to screen the soil with small particle sizes. The rotating shaft 15 penetrates through the collection box 10 and is fixed with a plurality of cams 16. The cams 16 are used to strike the sieve plate 12 to vibrate and loosen the agglomerated soil. The first gears 17 are fixed at both ends of the rotating shaft 15 and mesh with the first racks 18 fixed on the moving table 1.

[0053] Specifically, when the moving plate 5 drives the sampling cylinder 7 to move downward, the collection box 10 is pushed to move to one side through the connecting rod 13. At this time, the first gear 17 rolls along the first rack 18, driving the rotating shaft 15 and the cam 16 to rotate. The cam 16 strikes the sieve plate 12, vibrating and loosening the soil on the sieve plate 12 and screening the soil with small particle sizes, which is discharged into the collection groove 38 through the discharge port 14.

[0054] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 , a rectangular groove 20 is arranged at the bottom of the moving table 1 and is communicated with the circular hole 19. The lead screw 21 is rotatably connected inside the rectangular groove 20, and the thread directions of the two lead screws 21 are opposite. A U-shaped frame 35 is arranged inside the rectangular groove 20. A rotating cylinder 36 rotates inside the U-shaped frame 35 and is used to remove plant debris on the ground.

[0055] Referring to Figure 2 , Figure 8 and Figure 9 , the adjustment structure mainly consists of a moving block 27, a lead screw 21, a round shaft 28, a U-shaped seat 29, a third gear 31, a third rack 32, a round rod 33, a spring 34, as well as a U-shaped frame 35 and a rotating cylinder 36.

[0056] The moving block 27 and the lead screw 21: The moving block 27 is slidably arranged on the top inner wall of the rectangular groove 20 and is threadedly connected to the lead screw 21. When the lead screw 21 rotates, due to the thread action, the moving block 27 will move along the axial direction of the lead screw 21.

[0057] Circular shaft 28 and U-shaped seat 29: The circular shaft 28 rotates through the moving block 27, and a U-shaped seat 29 is fixedly sleeved on its outer wall. In this way, when the moving block 27 moves, it will drive the U-shaped seat 29 to move together.

[0058] Third gear 31 and third rack 32: One end of the circular shaft 28 passes through the U-shaped seat 29 and is fixed with a third gear 31, while a third rack 32 is fixed on one inner wall of the rectangular groove 20. When the moving block 27 drives the third gear 31 to move along the third rack 32, due to the meshing effect, the third gear 31 will drive the U-shaped seat 29 to rotate counterclockwise by 90°, making the U-shaped frame 35 vertically placed.

[0059] Round rod 33 and spring 34: A round rod 33 is fixed on one side of the U-shaped seat 29. One end of the round rod 33 extends slidably into the U-shaped frame 35 and is sleeved with a spring 34 fixedly connected to the U-shaped seat 29. The other end of the spring 34 is fixedly connected to one side of the second gear 25. In this way, after the U-shaped seat 29 rotates, the U-shaped frame 35 will move downward under the action of the spring 34 until the rotating cylinder 36 closely adheres to the ground.

[0060] Rotating cylinder 36: Multiple conical spikes are fixed on the outer wall of the rotating cylinder 36 for removing gravel and plants on the ground. When the lead screw 21 drives the moving block 27 to move, the rotating cylinder 36 will first contact and clean the gravel and plants on the ground to be sampled by the sampling cylinder 7, and then when the bottom end of the sampling cylinder 7 penetrates the round hole 19, the rotating cylinder 36 just moves away from the round hole 19 to avoid obstructing the sampling cylinder 7.

[0061] Refer to Figure 3 、 Figure 7 and Figure 8 As shown in

[0062] Relieving groove 37 and second rack 26: The relieving groove 37 is arranged on the top of the moving table 1, and the second rack 26 is slidably connected in the relieving groove 37, and its top is fixedly connected to the bottom of the collection frame 10. When the collection frame 10 moves outward, it will drive the second rack 26 to move together.

[0063] Drive shaft 22 and second gear 25: The drive shaft 22 is rotatably connected to the bottom inner wall of the relieving groove 37, and a second gear 25 meshing with the second rack 26 is fixed to its top end. In this way, when the second rack 26 moves, it will drive the second gear 25 and the drive shaft 22 to rotate.

[0064] The first bevel gear 23 and the second bevel gear 24: The bottom end of the drive shaft 22 extends rotatably into the rectangular groove 20 and is fixed with the first bevel gear 23. The outer wall of the lead screw 21 is fixedly sleeved with a second bevel gear 24 that meshes with the first bevel gear 23. Therefore, when the drive shaft 22 rotates, it will drive the lead screw 21 to rotate through the meshing action of the first bevel gear 23 and the second bevel gear 24, thereby driving the adjustment structure to operate.

[0065] Refer to Figure 8 and Figure 9 , a damping bearing 30 is fixed in the moving block 27, and the round shaft 28 passes through the damping bearing 30. When the moving block 27 drives the third gear 31 to disengage from the third rack 32, the U-shaped seat 29 is already vertically placed under the action of the third rack 32. At this time, the moving block 27 continues to move, but under the action of the damping bearing 30, it can avoid unnecessary shaking of the round shaft 28 and the U-shaped seat 29, ensuring the stability and accuracy of the entire adjustment process.

[0066] Refer to Figure 1 , at the four corners of the bottom of the moving table 1, we respectively installed four universal wheels 39. These universal wheels 39 are firmly fixed to the bottom of the moving table 1 by bolts or other fasteners to ensure that the entire device can be stably supported and the device can move flexibly on the ground. In addition, on one side of the top of the moving table 1, we welded or bolted an armrest 40. The armrest 40 is made of a strong and durable material, and its shape and height are designed to facilitate the operator to hold and push the moving table 1 for movement.

[0067] Refer to Figure 6 , on the inner wall of the bottom of the collection box 10, we welded or bolted a tilted inclined panel 11. The tilt angle of the inclined panel 11 is carefully designed to ensure that the soil can smoothly slide along it to the discharge port 14. In this way, after collecting the soil sample, by slightly tilting or vibrating the collection box 10, the soil can naturally slide to the discharge port 14, facilitating subsequent soil discharge operations.

[0068] Through the above specific implementation manners, the present invention can efficiently and accurately complete the inspection and sampling work of the soil, and at the same time automatically clean the plant debris in the sampling area, improving the work efficiency and sampling quality.

[0069] Embodiment 2

[0070] Reference Figure 10 and Figure 11, based on the improvement of Example 1: a through hole 41 is opened inside the moving platform 1, one end of a lead screw 21 passes through the through hole 41 and extends into the inside thereof, and a first synchronous wheel 42 is fixedly installed at the end. A second synchronous wheel 43 is rotatably connected to the inner wall of one side of the through hole 41 through a bearing. The first synchronous wheel 42 and the second synchronous wheel 43 are connected by a synchronous belt to ensure that the two can rotate synchronously.

[0071] A discharge hole 49 connected to the collecting tank 38 is provided on one side of the moving platform 1, and the size and position of the discharge hole 49 are designed according to the actual situation of the collecting tank 38. A transmission shaft 44 is rotatably connected in the discharge hole 49, and one end of the transmission shaft 44 passes through the collecting tank 38 and extends to the inside of the through hole 41. On the outer wall of the transmission shaft 44, a sleeve 45 is slidably connected through the cooperation of the slide groove and the slider, and the sleeve 45 can slide freely on the transmission shaft 44 but can also rotate with it.

[0072] A lever 46 is fixed to one end of the sleeve 45 close to the second synchronous wheel 43, and a plurality of paddles 47 are fixed to one side of the second synchronous wheel 43. The positions and shapes of the lever 46 and the paddles 47 are precisely designed to ensure that when the sleeve 45 moves to a specific position, the lever 46 can effectively cooperate with the paddles 47, thereby driving the sleeve 45 and the transmission shaft 44 to rotate.

[0073] On the outer wall of the transmission shaft 44, a conveying roller 48 is fixedly mounted in the discharge hole 49. The outer surface of the conveying roller 48 is designed with appropriate textures or protrusions to increase the friction between the roller and the soil, ensuring that the soil can be smoothly transported to the outside. When it is necessary to discharge the soil sample, the sleeve 45 is pushed to one side by the push plate 51 to the position where the lever 46 and the paddle 47 cooperate. At this time, the screw 21 is started to rotate, driving the second synchronous wheel 43, the paddle 47, the lever 46, the sleeve 45, the transmission shaft 44 and the conveying roller 48 to rotate in sequence to realize the discharge of the soil sample. At the same time, the rotation of the conveying roller 48 can further mix the soil samples at multiple different positions to improve the uniformity of the soil sample.

[0074] A guide plate 50 is fixedly mounted on the inner wall of the collecting trough 38 on one side away from each other. The shape and inclination angle of the guide plate 50 are reasonably designed to ensure that the soil sample can slide smoothly along it to the discharge hole 49, further assisting the soil discharge operation.

[0075] Through the above-mentioned specific implementation methods, we have successfully realized the soil discharge and mixing functions of a soil inspection and sampling device for national land space planning, and improved the efficiency and accuracy of soil sample processing.

[0076] A method for using a soil inspection and sampling device for national land space planning comprises the following steps:

[0077] S1. Move the mobile station 1 to a specified position, insert the sampling cylinder 7 into the soil by rotation to complete the soil collection, and perform soil collection at multiple different positions. After the collected soils are mixed, remove the plant roots and stones in them for later soil testing. Specifically, drive the lead screw 3 to rotate through the motor. The lead screw 3 drives the sampling cylinder 7 to penetrate the round hole 19 into the soil through the moving plate 5 for soil collection. At the same time, drive the motor 6 to drive the sampling cylinder 7 to rotate to enable the sampling cylinder 7 to smoothly insert into the soil.

[0078] S2. When the moving plate 5 drives the sampling cylinder 7 to move downward, the moving plate 5 pushes the collection frame 10 to move to one side through the connecting rod 13, and the collection frame 10 disengages from below the sampling cylinder 7 to prevent the collection frame 10 from obstructing the movement of the sampling cylinder 7. Additionally, when the collection frame 10 moves, the rotation shaft 15 and the cam 16 are driven to rotate through the cooperation of the first gear 17 and the first rack 18. The cam 16 is used to strike the sieve plate 12 to disperse the caked soil on the sieve plate 12 and screen the soil with small particle sizes. During the vibration process, the soils at different positions can also be mixed. The inclined panel 11 guides the soil and discharges it into the collection tank 38 through the discharge port 14.

[0079] S3. When the collection frame 10 moves outward, the drive shaft 22 and the first bevel gear 23 are driven to rotate through the cooperation of the second rack 26 and the second gear 25. The first bevel gear 23 and the second bevel gear 24 cooperate to drive the lead screw 21 to rotate. The lead screw 21 drives the moving block 27 to move to the right. The moving block 27 synchronously drives the round shaft 28 to move. The round shaft 28 drives the U-shaped seat 29 to rotate counterclockwise by 90° under the action of the third rack 32 and the third gear 31, so that the U-shaped frame 35 can be vertically placed. And the U-shaped frame 35 moves downward under the action of the spring 34 until the rotating cylinder 36 is close to the ground. Then drive the rotating cylinder 36 to rotate through the motor. Therefore, when the lead screw 21 drives the moving block 27 to move, the rotating cylinder 36 can remove the gravel and plants on the ground to be sampled by the sampling cylinder 7. When the bottom end of the sampling cylinder 7 penetrates the round hole 19, the rotating cylinder 36 just moves away from the round hole 19 to prevent the rotating cylinder 36 from obstructing the sampling cylinder 7, so that the sampling cylinder 7 can smoothly collect the soil and avoid the soil sample being mixed with plants and gravel.

[0080] S4. When the sampling cylinder 7 finishes soil collection, the sampling cylinder 7 resets upward. At the same time, the U-shaped frame 35, the rotating cylinder 36, and the collection frame 10 reset synchronously. After the sampling cylinder 7 moves above the collection frame 10, the output shaft of the electric push rod 8 pushes the push plate 9 to move downward to discharge the soil in the sampling cylinder 7 into the collection frame 10.

[0081] S5. Additionally, when it is necessary to take out the soil sample in the collection tank 38, the sleeve 45 is pushed to move to one side by the push plate 51. The sleeve 45 drives the lever 46 to move. The lever 46 just cooperates with the dial 47. Therefore, when the lead screw 21 drives the second synchronous wheel 43 to rotate, the second synchronous wheel 43 drives the transmission shaft 44 and the conveying roller 48 to rotate through the cooperation of the lever 46 and the dial 47, so as to discharge the soil sample to the outside. Moreover, when the conveying roller 48 rotates, it can further mix the soil samples at multiple different positions.

[0082] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 6 are common knowledge, and they all belong to conventional means or well-known common sense. Therefore, they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
