Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and particularly to a soil sample collection device for garden planting. Background Art

[0002] Garden planting requires an assessment of soil fertility and nutrient status. By collecting soil samples, the nutrient content in the soil, such as key elements like nitrogen, phosphorus, and potassium, can be understood, providing a scientific basis for rational fertilization, improving crop yield and quality. Additionally, it can evaluate the soil pollution status, facilitating the adoption of effective treatment measures. During the soil sample collection process, multiple samplings need to be carried out at different positions. Through multiple samplings, the representativeness and collection amount of the samples can be ensured. To control the entire sampling range and improve the representativeness of the samples, the sampling points should be as uniform and random as possible. Common distribution methods include zigzag or serpentine (S-shaped) sampling, which can better overcome the errors that may be caused by agricultural technical measures such as tillage and fertilization. The soil collection depth and sampling amount at each sampling point should be uniform. Before soil sample analysis, the soil samples need to be placed in an air-drying tray, spread out into a thin layer, first remove the debris in the soil, crush the soil clods with a wooden stick, and wait for natural air-drying and other steps.

[0003] However, deficiencies have been found in the use of existing soil sample collection devices. For example, when sampling garden soil, since the soil surface is covered with debris such as plants and stones, these debris will be collected together with the soil during sampling, and the staff needs to remove these debris, thus increasing the workload of soil analysis preparation. In addition, after plants and stones and other impurities enter the cylinder, they will be squeezed at the top of the cylinder and occupy space, thus affecting the soil collection amount, and it is difficult to maintain the consistency of the soil collection amount during multiple samplings. Therefore, the present application provides a soil sample collection device for garden planting to meet the needs. Summary of the Invention

[0016] By providing a volute spring, when controlling the rotation of the rotating rod, the volute spring will gradually tighten; when the pressure on the rotating rod is stopped, the volute spring will gradually relax and drive the rotating rod back to its original position.

[0043] As Figures 1 to 16 shown, an embodiment of the present invention provides a soil sample collection device for garden planting, including a support rod 1 and a fixed handle 2. The bottom end of the support rod 1 is fixedly connected with a fixed disk 3 and a first sampling cylinder 4. A sleeve 34 is slidably connected to the peripheral side wall of the support rod 1. One end of the sleeve 34 is fixedly connected with a moving handle 28, and the other end of the sleeve 34 is fixedly connected with a push plate 22 that slides within the first sampling cylinder 4. It further includes a separation assembly installed on the fixed disk 3. The separation assembly includes a second sampling cylinder 5 rotatably connected to the first sampling cylinder 4. After the soil is inserted into the second sampling cylinder 5 and the first sampling cylinder 4, the separation assembly is controlled to separate the soil in the second sampling cylinder 5 and the first sampling cylinder 4, and at the same time, the push plate 22 pushes out the soil in the first sampling cylinder 4.

[0044] As Figures 1 to 9As shown, the separation component includes a first stop post 6 fixedly connected to the outer peripheral side wall of the second sampling cylinder 5, and a second stop post 8 fixedly connected to the outer peripheral side wall of the first sampling cylinder 4. A fixing rod 7 rotatably connected to the second stop post 8 is fixedly connected to the first stop post 6; a fixing seat 10 is fixedly connected to the top end of the fixing plate 3. A rotating rod 11 is rotatably connected inside the fixing seat 10. A second gear 12 and a first gear 9 are respectively fixedly connected to the peripheral side walls of the rotating rod 11 and the fixing rod 7; a linear groove 14 and a curved groove 15 are formed in the peripheral side wall of the rotating rod 11. The curved groove 15 is arranged around the peripheral side wall of the rotating rod 11, and the top ends of the linear groove 14 and the curved groove 15 are in a communicating state; a connecting rod 13 passing through the fixing plate 3 is fixedly connected between the sleeve 34 and the push plate 22. The connecting rod 13 drives the push plate 22 to slide inside the first sampling cylinder 4. A sliding column 16 slidably matched with the linear groove 14 and the curved groove 15 is fixedly connected to the peripheral side wall of the connecting rod 13, and the sliding column 16 is close to the top end of the connecting rod 13; in the default state, the first sampling cylinder 4 and the second sampling cylinder 5 are in a combined state, and the first sampling cylinder 4 and the second sampling cylinder 5 are aligned. When in use, the combined first sampling cylinder 4 and second sampling cylinder 5 are inserted into the soil so that the soil fills the two sampling cylinders, and then the sampling cylinders are directly pulled out; by pushing down the moving handle 28, the sleeve 34 drives the push plate 22 to move in the two sampling cylinders, and a complete sample can be taken out; when the upper layer of soil needs to be taken out, the combined first sampling cylinder 4 and second sampling cylinder 5 are inserted into the soil so that the soil fills the two sampling cylinders. By controlling the fixing handle 2 to rotate the support rod 1, the overall support rod 1 drives the first sampling cylinder 4 to move at an angle. Since the two sampling cylinders are staggered at an angle, the upper and lower layers of the soil are separated.

[0045] By arranging the connecting rod 13 and the curved groove 15 and the linear groove 14 formed on the rotating rod 11, since the second sampling cylinder 5 is fixed in the soil by inserting the first stop post 6, the second sampling cylinder 5 is kept in a stable state. When the support rod 1 is rotated, the fixing plate 3 rotates around the fixing rod 7. At the same time, the rotating rod 11 on the fixing plate 3 rotates through the meshing of the first gear 9 and the second gear 12. During this process, the curved groove 15 on the rotating rod 11 guides the sliding column 16 to move, so that the sliding column 16 pushes the connecting rod 13 to move along the curved groove 15, and further promotes the connecting rod 13 to move downward. Therefore, while the first sampling cylinder 4 is rotated, the connecting rod 13 drives the push plate 22 to move downward, thereby pushing out the upper layer of soil; when the sleeve 34 is directly pushed downward by the moving handle 28, at this time the rotating rod 11 does not rotate, and the sliding column 16 on the connecting rod 13 slides in the linear groove 14, so that there is no interference with the connecting rod 13. Therefore, the soil can be automatically pushed out when the sampling cylinder is rotated, without additional operation steps, and the use process is convenient and fast.

[0046] In addition, both the first stop post 6 and the second stop post 8 are designed as inclined plane structures. When the first sampling cylinder 4 and the second sampling cylinder 5 are combined together, the first stop post 6 is aligned with the second stop post 8. In this combined state, when the sampling cylinder is inserted into the soil, the inclined plane structure helps the cylinder body to break through the soil. At the same time, when the first sampling cylinder 4 is rotated, the first stop post 6 plays a limiting role to prevent the problem that the rotation of the first sampling cylinder 4 causes the rotation of the second sampling cylinder 5.

[0047] As Figure 5 , Figure 8 shown, a detachable housing 17 is installed at the top end of the fixed disk 3. A fixed block 19 is fixedly connected to the top end of the housing 17. A clamping groove is formed in the fixed block 19, and a detachable scroll spring 20 is installed in the clamping groove. A slot 21 is formed at the top end of the rotating rod 11. The inner end of the scroll spring 20 is inserted into the slot 21 for fixation. By setting the scroll spring 20, its outer end is fixed in the clamping groove, and its inner end is fixed in the slot 21 at the top end of the rotating rod 11. When the rotation of the rotating rod 11 is controlled, the scroll spring 20 will gradually tighten. When the pressure on the rotating rod 11 is stopped, the scroll spring 20 will gradually relax and drive the rotating rod 11 back to its original position. Therefore, after the support rod 1 is rotated to drive the push plate 22 to push out the soil and the pressure on the support rod 1 is stopped, the push plate 22 and the support rod 1 will automatically reset without manual reset, thus simplifying the operation process of soil separation.

[0048] As Figure 9 , Figure 10 shown, a fixed ring body 26 is fixedly connected between the sleeve 34 and the connecting rod 13. A connecting channel 24 communicating with the fixed ring body 26 is formed in the connecting rod 13. A water outlet 25 is formed at one end of the connecting channel 24 far from the fixed ring body 26. A plurality of fixing strips 23 are fixedly connected to the circumferential side wall of the push plate 22. The ends of the plurality of fixing strips 23 far from the push plate 22 are commonly fixedly connected to a push ring 35. The push ring 35 contacts the inner walls of the first sampling cylinder 4 and the second sampling cylinder 5. The moving handle 28 is of a hollow structure, and an elastic water bag 29 is installed in the hollow structure. A through groove 30 communicating with the hollow structure is formed at the bottom end of the moving handle 28, and a pressing handle 31 is hinged. A pressing plate 32 matching the size of the through groove 30 is fixedly connected to the top end of the pressing handle 31. A water pipe 27 is fixedly connected to the outer wall of the fixed ring body 26. One end of the water pipe 27 far from the fixed ring body 26 is inserted into the moving handle 28 and connected to the elastic water bag 29. A water filling port is further provided on the elastic water bag 29, and a cover body is provided on the water filling port. A switching valve 33 is provided on the water pipe 27. The switching valve 33 is a prior art, and the communication or closing state of the water pipe 27 is controlled according to needs. The size and capacity of the elastic water bag 29 are set according to requirements.

[0049] By providing a connection channel 24 in the connecting rod 13, the communication between the connecting rod 13, the water pipe 27 and the fixed ring body 26 is achieved; by providing an elastic water bladder 29 in the movable handle 28, after the current sampling work is completed, by pressing the pressing handle 31 on the movable handle 28, the pressing plate 32 will apply pressure to the elastic water bladder 29. During this process, the water in the elastic water bladder 29 flows into the two sampling cylinders through the connection channel 24 and the water outlet 25. Subsequently, by repeatedly pushing and pulling the movable handle 28, the push plate 22 and the push ring 35 slide in the two sampling cylinders for scrubbing, ensuring timely cleaning of the sampling cylinders, thereby preventing the problem that if the residual samples in the sampling cylinders are not completely removed during multiple samplings at different positions, it will affect the sampling volume; in addition, if the soil at the sampling position is relatively dry, the above structure can also moisten the sampling position, facilitating the insertion of the sampling cylinder into the dry soil for sampling.

[0050] As Figure 9 shown, a plurality of the fixing bars 23 are annularly arrayed with the push plate 22 as the center. The water outlets 25 are at least two, and the two water outlets 25 are symmetrically arranged with the push plate 22 as the center, and the center of the push plate 22 gradually inclines towards the periphery of the bottom wall; since the water outlets 25 are symmetrically arranged, when water flows out, the water flow can be evenly sprayed into the sampling chamber through these symmetric water outlets 25, thereby improving the uniformity of water spraying; in addition, if the soil blocks the water outlets 25, by continuously pressing the elastic water bladder 29 to apply pressure, the soil blocking the water outlets 25 can be extruded.

[0051] As Figure 9 shown, the bottom widths of the fixing bars 23 and the push ring 35 are greater than the top widths of the fixing bars 23 and the push ring 35. The tops of the fixing bars 23 and the push ring 35 are both inclined surface structures. By setting the upper ends of the fixing bars 23 and the push ring 35 as inclined surface structures, and the upper end of the push plate 22 gradually inclines towards the periphery, when the push plate 22 moves in the sampling cylinder for cleaning, the inclined surface structure helps the ash water to flow down, reducing the accumulation of ash water; since the lower widths of the fixing bars 23 and the push ring 35 are greater than their upper widths, and a plurality of fixing bars 23 are arranged in an annular array, when the push plate 22 pushes out the soil, the plurality of fixing bars 23 can increase the contact area with the soil, both achieving the purpose of facilitating cleaning and being beneficial to the pushing out of the soil.

[0052] The straight groove 14, the curved groove 15 and the sliding column 16 are all arc-shaped structures.

[0053] As Figure 3 shown, the bottom end of the housing 17 is fixedly connected to a pedal 18 which is an integral structure. The pedal 18 is located above the first sampling cylinder 4 and the second sampling cylinder 5. By setting the housing 17 and the pedal 18 as an integral structure, it is convenient for assembly.

[0054] The working principle of the technical solution provided by the present invention is as follows: Whether to separate the top layer of soil is selected according to the soil debris situation. When taking a complete sample, the first sampling cylinder 4 and the second sampling cylinder 5 in the combined state are inserted into the soil so that the soil fills the two sampling cylinders. Then, the sampling cylinders are directly pulled out, and the moving handle 28 is pushed downward, so that the sleeve 34 drives the push plate 22 to push out the complete soil sample in the sampling cylinder.

[0055] When it is necessary to separate the upper layer of soil, the first sampling cylinder 4 and the second sampling cylinder 5 in the combined state are inserted into the soil so that the soil fills the two sampling cylinders. At this time, by controlling the fixed handle 2 to rotate the support rod 1, the fixed disk 3 rotates around the fixed rod 7. Since the two sampling cylinders are staggered in angle, the upper and lower layers of the soil are separated; at the same time, the rotating rod 11 on the fixed disk 3 rotates through the meshing of the first gear 9 and the second gear 12. During this process, the curved groove 15 on the rotating rod 11 guides the sliding column 16 to move, so that the sliding column 16 pushes the connecting rod 13 to move along the curved groove 15, prompting the connecting rod 13 to move downward. Therefore, while rotating the first sampling cylinder 4, the connecting rod 13 will drive the push plate 22 to move downward and push out the upper layer of soil. After the sampling cylinder is reset, the separated soil sample is taken out through the push plate 22.

[0056] After the soil sampling work at the current position is completed, by pressing the pressing handle 31 on the moving handle 28, the pressing plate 32 applies pressure to the elastic water bag 29. During this process, the water in the elastic water bag 29 flows into the two sampling cylinders through the connecting channel 24 and the water outlet 25. Subsequently, by repeatedly pushing and pulling the moving handle 28, the push plate 22 and the push ring 35 slide in the two sampling cylinders for brushing to ensure timely cleaning of the sampling cylinders, thereby preventing the problem that if the residual sample in the sampling cylinder is not completely removed during multiple samplings at different positions, it will affect the sampling volume.

[0057] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.

[0058] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
