Description

Garden soil sampling and testing equipment Technical Field

[0001] The invention relates to the technical field of garden soil sampling, in particular to garden soil sampling and detection equipment. Background Art

[0002] Garden soil sampling is an important step in understanding the physical and chemical properties, nutrient levels and pollution status of garden soil. The main purpose of garden soil sampling is to understand the physical and chemical properties of soil such as nutrient content, texture, pH, etc., and provide a scientific basis for the rational fertilization, irrigation and soil improvement of garden plants. At the same time, sampling can also monitor soil pollution status and ensure the health and stability of the garden ecosystem. The layout of sampling points should be based on comprehensive considerations of factors such as garden soil type, terrain, vegetation distribution and pollution status.

[0003] For example, the patent application number published on the China Patent Network is: 202311536864.0, and the patent name is: A sampling and collecting device for garden soil testing, including a frame and a sampling component. The sampling component includes a barrel and a lifting drive assembly. A locking switching assembly is provided between the lifting drive assembly, the barrel and the frame. A piston member is sealed and lifted in the barrel. The piston member divides the barrel into upper and lower air pressure compression release areas and a collection area. The air pressure compression release area is divided into upper and lower air pressure conveying areas and a compression waiting area by a telescopic sealing assembly. A top opening component is fixed at the upper end of the piston member, and a cutting assembly is provided at the lower end of the barrel. When the locking switching assembly is switched to lock the barrel and the lifting drive assembly, after the soil is collected to the specified volume, the cutting unit can be extended horizontally to cut off the soil, and then the air bag layer expands to compress the soil; when the locking switching assembly is switched to lock the barrel and the frame, the lifting drive assembly descends to drive the cutting unit to reset, the air bag layer contracts, and the soil is discharged.

[0004] However, the structure of the existing sampling device is relatively simple. The vehicles used for movement are set on both sides of the vehicle. The connection between the vehicle and the sampling device is not stable enough and cannot effectively resist external forces. The ground conditions are complex, such as unevenness and slipperiness, which increases the risk of vehicle displacement. As a result, the vehicle is prone to displacement during static sampling. The displacement will not only affect the accuracy of the sampling, but may also cause damage to the sampling device and the surrounding environment.

[0005] In addition, during the sampling process, the continuously rotating drill bit is prone to collide with the ground, which will not only damage the drill bit, but may also cause damage to the overall structure of the sampling device. The collision may also generate noise and vibration, affecting the stability and safety of the sampling process. Moreover, the control accuracy of the drill bit is not high enough, and it is impossible to accurately judge the distance from the ground.

[0006] Finally, after sampling is completed, the user needs to manually collect the soil and fill it into the testing equipment for analysis and testing. The connection between the sampling device and the testing equipment is not smooth enough, and there is a lack of automated soil collection and filling mechanism. This process is time-consuming and labor-intensive, and can easily affect the continuity of the test. Manual operation may also introduce errors and reduce the accuracy of the test.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] As shown in Figures 1 to 8, the present invention provides a garden soil sampling and testing device, including a frame 1;

[0042] The detection module 2 and the sampling module 3 are respectively installed on both sides of the top of the frame 1;

[0043] Wheels 5 are installed at the four corners of the frame 1 through the adjustment structure 4. The wheels 5 can roll and support the frame 1. The adjustment structure 4 can control the flipping of the wheels 5 and move them from the four corners of the frame 1 to the top of the frame 1. A transmission structure 6 for controlling the flipping of the adjustment structure 4 is provided inside the frame 1. The transmission structure 6 is interconnected with the sampling module 3 through a linkage structure 7. During the process of the transmission structure 6 controlling the flipping of the adjustment structure 4, the linkage structure 7 can be used to control the sampling module 3 to automatically reduce the sampling.

[0044] Referring to Figure 4, the adjustment structure 4 is responsible for connecting the frame 1 and the wheel 5, and allowing the wheel 5 to rotate and swing around the connecting rod 9 as the axis under certain circumstances. The adjustment structure 4 includes connecting blocks 8 fixedly connected to the four corners of the surface of the frame 1. The connecting blocks 8 are fixedly connected to the four corners of the surface of the frame 1 and serve as support and connection points for the wheel 5 and the sleeve 10. The connecting blocks 8 are generally designed as solid block structures with sufficient strength and rigidity to support the weight of the wheel 5 and the sleeve 10 and transmit the rolling force from the wheel 5. The connecting rod 9 is fixedly connected to the surface of the connecting block 8 and extends to the outside of the frame 1. The connecting rod 9 is designed to be cylindrical. Its diameter or side length is determined according to the size of the wheel 5 and the sleeve 10 and the required strength. The sleeve 10 is sleeved on the surface of the connecting rod 9 and maintains a certain gap with the connecting rod 9 to allow the sleeve 10 to rotate and swing on the connecting rod 9. One end of the sleeve 10 is movably connected to the wheel 5, so that the wheel 5 can roll inside the sleeve 10. The design of the sleeve 10 gives it a certain rigidity and toughness, which can withstand the weight and rolling force of the wheel 5 and allow the wheel 5 to rotate and swing around the connecting rod 9 as the axis when needed. The end of the wheel 5 close to the sleeve 10 extends into the interior of the sleeve 10 and is movably connected to the sleeve 10. The wheel 5 can roll inside the sleeve 10 to provide rolling support when the equipment moves. The transmission structure 6 can carry the sleeve 10 and the wheel 5 to rotate and swing around the connecting rod 9 as the axis.

[0045] As a technical optimization solution of the present invention, the design of the connecting block 8, the connecting rod 9 and the sleeve 10 allows the wheel 5 to rotate and swing around the connecting rod 9 as the axis. This structure is simple and effective, and can stably control the flipping of the wheel 5 to ensure the stability of the equipment under different working conditions. The wheels 5 installed at the four corners of the frame 1 through the adjustment structure 4 can not only provide rolling support when the equipment moves, but also flip to the top of the frame 1 during sampling to provide space for the sampling module 3 to descend for sampling. At the same time, the design of the support legs 35 and the spring plate 36 can provide additional stability after the equipment reaches the sampling point, ensuring the smooth progress of the sampling process.

[0046] Referring to Figure 8, the transmission structure 6 includes a fork 11 fixedly connected to the outer end of the connecting rod 9, and a connecting frame 12 is provided on both sides of the top of the frame 1. The outer side of the connecting frame 12 is fixedly connected to the limit rod 13, and the inner side of the connecting frame 12 is fixedly connected to the bracket 14. A two-way screw 15 and a guide rod 16 are respectively installed on both sides of the inside of the frame 1. The bracket 14 is respectively sleeved on the surface of the two-way screw 15 and the guide rod 16. The guide rod 16 is slidably connected to the bracket 14, and the two-way screw 15 is threadedly connected to the bracket 14. The limit rod 13 extends away from the side of the connecting frame 12 to the inside of the fork 11 and is slidably connected to the fork 11. The surface of the limit rod 13 is set to be inclined to extend outward. During the process of moving outward, the limit rod 13 can use the inclined part to squeeze the fork 11 so that it carries the sleeve 10 to swing. The surface of the frame 1 is fixedly connected to a transmission motor 17 for driving the two-way screw 15 to rotate.

[0047] As a technical optimization solution of the present invention, precise control of the flipping of the wheel 5 is achieved through the interaction between the limit rod 13 and the fork 11, and the cooperation between the bidirectional screw 15 and the guide rod 16. The introduction of the transmission motor 17 further improves the degree of automation and makes the operation easier.

[0048] Referring to Figure 3, the sampling module 3 includes a guide tube 18 fixedly connected to the inside of the frame 1, a drive motor 19 is provided on the top of the guide tube 18, and a sampling rod 20 is fixedly connected to the output end of the drive motor 19. The linkage structure 7 can carry the drive motor 19 down and make the sampling rod 20 contact the ground. A discharge port 21 corresponding to the detection module 2 is opened on the surface of the guide tube 18.

[0049] As a technical optimization solution of the present invention, the combination of the drive motor 19 and the sampling rod 20 realizes automated sampling, improves sampling efficiency and accuracy, and the design of the guide tube 18 and the discharge port 21 facilitates the collection and discharge of soil samples.

[0050] Referring to Figure 3, the detection module 2 includes a detection device 22 fixedly connected to the inside of the frame 1. The detection device 22 is an atomic absorption spectrophotometer commonly used in the prior art, which is used to determine the content of trace elements such as zinc, copper, iron, etc. in the soil. The detection device 22 is located on the right side of the discharge port 21. The surface of the detection device 22 is fixedly connected to a vertical plate 23, and the surface of the vertical plate 23 is movably connected to a transmission rod 24 through a bearing. The surface of the transmission rod 24 is fixedly connected to an extension plate 25, and the side of the extension plate 25 away from the transmission rod 24 is fixedly connected to a cover plate 26 located on the top of the detection device 22.

[0051] As a technical optimization solution of the present invention, the detection module 2 is located on the right side of the discharge port 21, which is convenient for receiving and processing soil samples. The vertical plate 23, transmission rod 24, extension plate 25 and cover plate 26 and other components together constitute a protective detection environment, ensuring the accuracy and safety of the detection process.

[0052] Referring to Figure 3, the linkage structure 7 includes a support block 27 fixedly connected to the top of the connecting frame 12, and the surface of the support block 27 is movably connected to a crank 28 through a pin, and the side of the crank 28 away from the support block 27 is movably connected to a supporting plate 29 through a pin. The supporting plate 29 is sleeved on the surface of the sampling rod 20 and fixedly connected to the bottom of the drive motor 19. During the process of the connecting frame 12 moving outward, the crank 28 can be used to pull the supporting plate 29 and carry the drive motor 19 down vertically.

[0053] As a technical optimization solution of the present invention, the interaction between the crank 28 and the supporting plate 29 enables the automatic down sampling of the sampling module 3 during the turning process of the wheel 5, which not only improves the sampling efficiency but also ensures the stability during the sampling process.

[0054] 5 , the surface of the guide tube 18 is movably connected to a cross bar 30 located on both sides of the discharge port 21 , and the surface of the cross bar 30 is sleeved with a discharge frame 31 surrounding the surface of the discharge port 21 . The discharge frame 31 can swing through the cross bar 30 and change the discharge direction.

[0055] As a technical optimization solution of the present invention, the cross bar 30 is connected to the guide tube 18, which can swing and change the discharge direction, so that the equipment can adjust the discharge method according to needs, thereby improving the flexibility and adaptability of the equipment.

[0056] With reference to Figure 5, the end of the cross bar 30 away from the guide tube 18 is fixedly connected to the rocker arm 32, and the end of the rocker arm 32 away from the cross bar 30 is movably connected to the roller 33 through a pin shaft. The bottom of the supporting plate 29 is fixedly connected to the extrusion rod 34 located on the outside of the guide tube 18. The surface of the extrusion rod 34 is set to be inclined. The side of the extrusion rod 34 away from the supporting plate 29 extends to the inner side of the rocker arm 32 and contacts the surface of the roller 33. When the supporting plate 29 carries the extrusion rod 34 to descend, it can use the inclined surface to squeeze the roller 33 and push the rocker arm 32 to swing. The rocker arm 32 that changes the swing angle can use the cross bar 30 to carry the discharge frame 31 to change the conveying direction so that the soil falls to the top of the detection equipment 22.

[0057] As a technical optimization solution of the present invention, the combination of the rocker arm 32 and the roller 33 allows the discharge frame 31 to automatically adjust the discharge direction according to the soil thickness during the sampling process, ensuring that the underlying soil can be accurately collected and transported to the detection equipment 22, thereby improving the sampling accuracy and efficiency.

[0058] Referring to Figure 6, the left and right sides of the top of the frame 1 are movably connected with support legs 35 through pins. The side of the support leg 35 away from the frame 1 extends to the outside of the frame 1. The outside of the frame 1 is fixedly connected with a spring plate 36 located at the bottom of the support leg 35. The side of the spring plate 36 away from the frame 1 can contact the bottom of the support leg 35.

[0059] As a technical optimization solution of the present invention, the combination of the support legs 35 and the spring plates 36 provides additional support stability for the equipment, especially after the wheel 5 flips over or when the equipment is working on uneven ground, thereby enhancing the stability and safety of the equipment.

[0060] Referring to Figure 6, a push rod 37 is fixedly connected to the outer side of the connecting frame 12, and a force plate 38 is fixedly connected to the side of the support leg 35 close to the frame 1. The force plate 38 extends to the outer side of the push rod 37 away from the frame 1. When the connecting frame 12 carries the push rod 37 and moves outward to a certain distance, it can squeeze the force plate 38 to make the support leg 35 swing and contact the ground.

[0061] As a technical optimization solution of the present invention, the interaction between the push rod 37 and the force plate 38 enables the device to automatically adjust the position of the support leg 35 during movement, ensuring the stability of the device during the sampling process and improving the degree of automation and ease of operation of the device.

[0062] Referring to Figure 7, the rest of the structure remains unchanged. The present invention proposes an automatic closing structure for the cover 26. The outer end of the transmission rod 24 is fixedly connected to a closing rod 39. The closing rod 39 extends to the outside of the force-bearing plate 38 away from the side of the transmission rod 24. When the connecting frame 12 carries the push rod 37 to move outward, it can synchronously squeeze the closing rod 39 so that it can carry the cover 26 through the transmission rod 24 to close.

[0063] The closing rod 39 is connected to the cover plate 26 through the transmission rod 24, which can automatically close the cover plate 26 during the movement of the equipment, protecting the detection equipment 22 from external interference, improving the reliability and safety of the equipment, and enabling the swing arm 32 to automatically close after the soil is filled.

[0064] Referring to Figure 7, the rest of the structure remains unchanged. The present invention proposes a structure for cleaning the soil on the surface of the detection equipment 22 after inspection. The top of the frame 1 is fixedly connected to the column 40, and the top of the column 40 is movably connected to the lever 41 through a pin. The lever 41 extends from the side of the column 40 to the top of the detection equipment 22 and contacts the surface of the detection equipment 22. The lever 41 can swing on the surface of the column 40 and remove the soil on the surface of the detection equipment 22. The side of the connecting frame 12 close to the lever 41 is fixedly connected to the driving rod 42 located on both sides of the lever 41. During the horizontal movement, the connecting frame 12 can use the driving rod 42 to squeeze the lever 41 to automatically swing and remove the soil on the surface of the detection equipment 22 after inspection.

[0065] The combination of the shifting rod 41 and the driving rod 42 can automatically remove the soil on the surface of the detection device 22 during the movement of the device, thereby ensuring the accuracy and continuity of the detection process and improving the automation level and detection efficiency of the device.

[0066] The working principle and use process of the present invention are as follows: the equipment is in a stationary state, the frame 1 is stably supported on the ground by the adjustment structure 4 installed at its four corners, the wheels 5 are located at the four corners of the frame 1, the sampling module 3 and the detection module 2 are respectively installed on both sides of the top of the frame 1 and are in a standby state, and a transmission structure 6 and a linkage structure 7 are provided inside the frame 1. The transmission structure 6 is connected to the adjustment structure 4, and the linkage structure 7 is connected to the sampling module 3. The operator holds the handle carried by the frame 1 and pushes the equipment to move to the target sampling point. At this time, the support legs 35 and the spring plate 36 remain in place and do not touch the ground. When the equipment reaches the sampling point, the operator starts to operate the transmission structure 6, which includes a fork 11 fixedly connected to the outer end of the connecting rod 9, a connecting frame 12 and the top of the frame 1 The two-way screw 15 and the guide rod 16 are respectively arranged on both sides of the frame 1, the limit rod 13 is fixedly connected to the outside of the connecting frame 12, the two-way screw 15 and the guide rod 16 are installed on both sides of the inside of the frame 1, and the operator drives the two-way screw 15 to rotate through the transmission motor 17 installed on the surface of the frame 1. Since the bracket 14 is respectively sleeved on the surfaces of the two-way screw 15 and the guide rod 16, and the guide rod 16 is slidably connected to the bracket 14, and the two-way screw 15 is threadedly connected to the bracket 14, the bracket 14 will move along the two-way screw 15 and the guide rod 16. As the bracket 14 moves, the limit rod 13 also gradually moves outward. As the two-way screw 15 rotates, the bracket 14 drives the limit rod 13 to move outward, and the inclined portion of the limit rod 13 gradually contacts the fork 11 and generates an extrusion force, thereby driving the fork 1 1 and the sleeve 10 rotate and swing, so that the wheel 5 gradually flips from the four corners of the frame 1 to the top of the frame 1, preparing for the sampling module 3 to descend for sampling. While the wheel 5 is flipping, the continuously moving connecting frame 12 carries the push rod 37 to move outward. The continuously moving connecting frame 12 can use the push rod 37 to squeeze the force plate 38. After the force is applied, the force plate 38 carries the support legs 35 to swing and contact the ground, providing additional support stability for the equipment. The transmission structure 6 also controls the sampling module 3 to automatically descend for sampling through the linkage structure 7. The linkage structure 7 includes components such as the support block 27, the crank 28, and the carrying plate 29. As the connecting frame 12 moves outward, the crank 28 pulls the carrying plate 29 to carry the drive motor 19 vertically downward, and the drive motor 19 descends. When the sampling rod 20 is lowered, the sampling rod 20 fixed at its output end also drops down and contacts the ground for sampling. After the sampling rod 20 drops to the ground, it collects soil samples. At this time, the discharge port 21 on the surface of the guide tube 18 begins to discharge the surface soil of the ground. The cross bars 30 on both sides of the discharge port 21 and the discharge frame 31 sleeved on the surface of the cross bars 30 can swing and change the discharge direction, so that the surface soil is directly discharged to the outside. After a period of discharge, the sampling rod 20 continues to go deeper to collect the bottom soil. When it is necessary to collect the bottom soil, the supporting plate 29 continues to drop with the squeezing rod 34. The squeezing rod 34 extends away from the side of the supporting plate 29 to the inner side of the swing rod 32 and contacts the surface of the roller 33. The squeezing rod 34 uses the inclined surface to squeeze the roller 33 and push the swing rod 32 to swing.The swing arm 32 changes its swing angle and carries the discharge frame 31 through the crossbar 30 to change the conveying direction, so that the bottom soil falls to the top of the detection device 22 for detection. After the bottom soil falls to the top of the detection device 22, the cover 26 on the top of the detection device 22 closes and starts working to analyze and detect the soil.

[0067] In summary, the garden soil sampling and testing equipment realizes the automation and integration of soil sampling through the ingenious design of the frame 1, adjustment structure 4, transmission structure 6, linkage structure 7, sampling module 3 and detection module 2. The modules work closely together, making the entire equipment compact and easy to carry and operate.
