Description

Technical Field

[0001] This application relates to the field of soil sampling technology, and more specifically, to a soil sampling device for agricultural technology promotion. Background Technology

[0002] Agricultural technology extension refers to a comprehensive activity that systematically applies agricultural technologies (including scientific and technological achievements and practical technologies in fields such as crop farming, forestry, animal husbandry, and fisheries) to the entire agricultural production process through trials, demonstrations, training, guidance, and consulting services. Its core objective is to improve agricultural production efficiency, ensure food security, and increase farmers' income through the implementation of technologies. Soil sampling provides key data support for the promotion of technologies such as soil testing and formula fertilization, soil improvement, and pest and disease control. As a fundamental link in agricultural technology extension, it directly affects the accuracy and effectiveness of technology application.

[0003] In related technologies, to facilitate the removal and preservation of soil samples taken by the sampler, for example, the prior art patent with publication number CN217132609U provides an agricultural technology promotion soil sampling device. This device has a sampling shell set on the side of the cylinder. When the cylinder is inserted into the soil, the sampling shell is pressed down, and the soil enters the sampling shell in the original accumulation manner without changing the layered structure of the soil, which is convenient for subsequent testing. By moving the control rod downward, the dividing plate can be moved to the bottom opening position of the sampling shell, which can prevent the soil from sliding down when it is taken out upward, making sampling very convenient.

[0004] Although the existing technical solutions mentioned above can facilitate sampling by moving the control lever downwards to slide the dividing plate to the bottom opening of the sampling housing, soil residue remains in the sampling tube after each sampling. In order to ensure the detection accuracy after soil sampling, the used sampling tube often needs to be cleaned before each sampling. Due to the complex internal structure of the sampling tube, the internal cleaning operation is relatively troublesome, which reduces the work efficiency at the sampling site.

[0005] In view of this, we propose a soil sampling device for agricultural technology promotion. Utility Model Content

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a soil sampling device for agricultural technology promotion, including a sampling cylinder 1, a drive shaft 2, a support plate 3, and a cleaning component 4. The drive shaft 2 is used to drive the sampling cylinder 1 to drill into the soil, and one end of the drive shaft 2 is detachably connected to the sampling cylinder 1. The support plate 3 is rotatably disposed at the other end of the drive shaft 2 and is used to support the power source of the drive shaft 2. The cleaning component 4 is disposed inside the sampling cylinder 1 and is driven by external force to move inside the sampling cylinder 1, and is used to clean the soil inside the sampling cylinder 1. The sampling cylinder 1 includes a cylinder body 11 and a side wall plate 12. The cylinder body 11 is detachably connected to the drive shaft 2. An arc-shaped groove 13 is opened on the outer side of the cylinder body 11. The side wall plate 12 is detachably disposed from the cylinder body 11 in cooperation with the arc-shaped groove 13, and is used to take out the soil sample inside. An end cap 14 is fixedly installed on the top of the cylinder 11, and the end cap 14 is fixedly connected to one end of the drive shaft 2. Teeth 15 are provided on the bottom of the cylinder 11. A flange 21 for connecting the end cap 14 is fixedly installed on one end of the drive shaft 2, and a motor 22 is installed on the other end of the drive shaft 2. The motor 22 is fixedly installed on the top of the support plate 3, and a protective cover 32 is fixedly installed on the outside of the support plate 3. A handle A31 is fixedly installed on the outside of the support plate 3, and a bearing sleeve 33 for supporting the drive shaft 2 is fixedly installed at the bottom of the handle A31.

[0037] During soil sampling, the sampling personnel adjust the sampling position and angle of the sampling device by holding the handle A31. Then, the motor 22 is started by the switch on the outside of the bearing plate 3 (not shown in the figure), which drives the drive shaft 2 to rotate. The drive shaft 2 drives the sampling cylinder 1 to rotate slowly. Since the bottom of the cylinder 11 is provided with teeth 15, the sampling cylinder 1 can be smoothly drilled into the soil. After drilling to a certain depth, the sampling cylinder 1 is pulled out upwards. Then, the side wall plate 12 located on the side wall of the cylinder 11 is disassembled to make it easy to take out the soil sample inside the cylinder 11 for preservation. After the soil is taken out, the side wall plate 12 is reassembled with the cylinder 11 according to the arc groove 13. Then, the cleaning component 4 inside the sampling cylinder 1 is used to clean the soil remaining on the inner wall of the sampling cylinder 1 to prevent the residual soil from affecting the subsequent soil test results.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The cleaning component 4 includes a brush disc 41 located between the cylinder 11 and the side wall plate 12. A slide rod 42 is fixedly mounted on the top of the brush disc 41 and rotatably mounted inside the end cap 14. A handle B43 is fixedly mounted on the other end of the slide rod 42. The drive shaft 2 is a hollow structure used to accommodate the slide rod 42. A groove 23 is formed on the side wall of the drive shaft 2, and the handle B43 is slidably mounted inside the groove 23. A fixing ring 24 is fixedly mounted on the outside of the drive shaft 2, and a sliding ring 25 is slidably mounted on the outside of the fixing ring 24. A support block 26 is fixedly mounted on the outside of the sliding ring 25 to support the handle B43. An opening 251 is formed on the side of the sliding ring 25 away from the support block 26, and a mating groove 261 is formed on the top of the support block 26 corresponding to the handle B43.

[0039] When the drive shaft 2 is driving the sampling cylinder 1 to take samples, in order to ensure that the cleaning component 4 does not interfere with the sampling process, after the handle B43 is lifted upward, the support block 26 is moved to the lower side of the handle B43 by rotating the slip ring 25. Then, the handle B43 is placed inside the mating groove 261 for circumferential limiting to prevent the handle B43 from falling off the support block 26 when the drive shaft 2 rotates. When cleaning the inside of the sampling cylinder 1, the handle B43 is first lifted slightly upward to disengage from the inner side of the mating groove 261. Then, the slip ring 25 is rotated so that the opening 251 is below the handle B43. At this time, the support block 26 and the handle B43 are offset from each other and will not interfere with the sliding of the handle B43. Then, by holding the handle B43, the slide rod 42 is pushed to slide inside the end cover 14, so that the slide rod 42 drives the brush plate 41 to clean the inner wall of the cylinder 11 and the side wall plate 12. During the cleaning process, if the soil moisture is high, the sampling cylinder 1 can be placed in water for cleaning as needed.

[0040] Reference Figure 3 and Figure 4A limiting block 121 is fixedly installed on the top of the side wall panel 12. A U-shaped groove 122 is opened on the inner side of the limiting block 121 corresponding to the slide rod 42. A notch 123 is opened on the inner side of the limiting block 121. A pin 124 is slidably installed on the top of the notch 123. A spring 125 is fixedly installed on the inner side of the notch 123. The spring 125 is located at the bottom of the pin 124. The pin 124 is engaged on the inner side of the end cover 14. A insertion hole 16 is opened on the inner side of the end cover 14 corresponding to the pin 124. A sliding pin 17 is slidably installed on the inner side of the insertion hole 16 for pressing the pin 124 to disengage from the insertion hole 16. A connecting plate 18 is fixedly installed on the top of the sliding pin 17. A fixing shaft 19 is slidably installed on the inner side of the connecting plate 18. The fixing shaft 19 is fixedly installed on the top of the end cover 14.

[0041] Before sampling from the sampling cylinder 1, the side wall plate 12 is assembled with the cylinder body 11. During assembly, the limiting block 121 at the top of the side wall plate 12 is inserted into the inner side of the cylinder body 11, and the side wall plate 12 and the arc groove 13 are engaged with each other. During the insertion of the limiting block 121, the end cap 14 and the limiting block 121 will squeeze the pin 124 and compress the spring 125. After the insertion is positioned, the pin 124 and the insertion hole 16 on the inner side of the end cap 14 are aligned with each other. At this time, the spring 125 automatically pushes the pin 124 into place. 4. Insert the pin into the inside of the socket 16 and lift the sliding pin 17 inside the socket 16. The connecting plate 18 at the top of the sliding pin 17 is always connected to the end cover 14 under the action of the fixed shaft 19. When the side wall plate 12 is removed to take out the internal soil sample, press the connecting plate 18 to make the sliding pin 17 push the pin 124 to compress the spring 125 and disengage it from the inside of the socket 16. Then, the side wall plate 12 is removed horizontally so that the side wall plate 12 can be installed and removed before and after soil sampling.

[0042] In summary, when using the soil sampling device for agricultural technology extension disclosed in this application, the side wall plate 12 is first assembled with the cylinder 11. During assembly, the limiting block 121 at the top of the side wall plate 12 is inserted into the inner side of the cylinder 11, and the side wall plate 12 and the arc groove 13 are engaged. During the insertion of the limiting block 121, the end cap 14 and the limiting block 121 will squeeze the pin 124 and compress the spring 125. After insertion and positioning, the pin 124 and the insertion hole 16 on the inner side of the end cap 14 are aligned. At this time, the spring 125 automatically inserts the pin 124 into the inner side of the insertion hole 16, realizing the quick installation of the side wall plate 12 and lifting the sliding pin 17 on the inner side of the insertion hole 16. The connecting plate 18 is always located outside the end cap 14 under the action of the fixed shaft 19; then, the sampling personnel adjust the sampling position and sampling angle of the sampling device by holding the handle A31, and then start the motor 22 by the switch on the outside of the bearing plate 3, so that the motor 22 drives the drive shaft 2 to rotate, and the drive shaft 2 drives the sampling cylinder 1 to rotate slowly. Since the bottom of the cylinder 11 is provided with teeth 15, the sampling cylinder 1 can be smoothly drilled into the soil. After drilling to a certain depth, the sampling cylinder 1 is pulled out upwards. Then, by pressing the connecting plate 18, the sliding pin 17 pushes the pin 124 to compress the spring 125 and disengage it from the inside of the insertion hole 16. Then, the side wall plate 12 is disassembled horizontally to remove the soil sample.

[0043] During the sampling process, in order to ensure that the cleaning component 4 does not interfere with the sampling process, the handle B43 needs to be lifted upwards before sampling. Then, by rotating the slip ring 25, the support block 26 is moved to the lower part of the handle B43. Then, the handle B43 is placed inside the mating groove 261 for circumferential limiting to prevent the handle B43 from falling off the support block 26 when the drive shaft 2 rotates. When cleaning the inside of the sampling cylinder 1, the handle B43 is first lifted slightly upwards to disengage from the inner side of the mating groove 261. Then, the slip ring 25 is rotated so that the opening 251 is below the handle B43. At this time, the support block 26 and the handle B43 are offset from each other and will not interfere with the sliding of the handle B43. Then, by holding the handle B43, the slide rod 42 is pushed to slide inside the end cover 14, so that the slide rod 42 drives the brush plate 41 to clean the inner wall of the cylinder 11 and the side wall plate 12. During the cleaning process, if the soil moisture is high, the sampling cylinder 1 can be placed in water for cleaning as needed.
