Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to an adjustable-depth farmland soil sampler. Background Technology

[0002] Soil samplers typically consist of a rod, a soil sampling tube, a pressing plate, etc. They can accurately collect soil samples at a depth of approximately 1 to 2 meters. The sampling tube opening is also relatively small, making it easy to insert into the soil. Its compact and practical features have made a significant contribution to biological research. Therefore, it is necessary to design an adjustable-depth farmland soil sampler.

[0003] Traditional soil samplers have a relatively simple internal structure, mostly consisting of a sampling tube and a handle. To use them, the operator must hold the handle to press the sampling tube into the soil and then pull it out. This method is cumbersome, time-consuming, and labor-intensive. Furthermore, because the entire sampling tube is inserted at once, it's difficult for the operator to adjust the sampling depth. When sampling at different depths, the operator must rely on their experience to control the insertion depth. This method has poor accuracy and is not suitable for beginners. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed adjustable-depth farmland soil sampler to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An adjustable-depth farmland soil sampler includes a mounting assembly. The mounting assembly includes a base, with a U-shaped mounting frame fixed to both sides of the base. A drive assembly is rotatably mounted on one side of the top of the base and placed inside the U-shaped mounting frame. A limiting assembly that cooperates with the drive assembly is fixedly mounted on the other side of the top of the base. An adjustment assembly placed outside the U-shaped mounting frame is fixedly mounted on the inner top of the drive assembly.

[0007] As a further optimization of this utility model, the driving assembly includes a driving screw rotatably mounted on one side of the top of the base, a servo motor rotatably connected to the top of the driving screw is fixedly inserted through one side of the top of the U-shaped mounting bracket, and a collection cylinder that slides through to the middle position inside the base is threaded onto the external thread of the driving screw.

[0008] As a further optimization of this utility model, the limiting component includes a threaded rod fixedly installed on the other side of the top of the base and connected to the top of the U-shaped mounting bracket, wherein the external thread of the threaded rod is fitted with an internal threaded sleeve that mates with the collection cylinder.

[0009] As a further optimization of this utility model, the adjustment component includes an adjustment block that is slidably located at the bottom of the collection tube, an adjustment screw that is threaded through to the top of the collection tube is rotatably installed on the top of the adjustment block, and measuring rods that are slidably installed through to the sides of the inside of the collection tube are fixedly installed on both sides of the top of the adjustment block, and a servo motor II that is fixedly connected to the top of the adjustment screw is installed on the top of the two measuring rods.

[0010] As a further optimization of this utility model, the top of the outer side of the collection cylinder is fixedly fitted with a limiting sleeve, and a connecting sleeve plate is fixedly installed on both sides of the limiting sleeve. One of the connecting sleeve plates is threadedly fitted onto the outside of the drive screw, and the other connecting sleeve plate is slidably fitted onto the outside of the threaded rod.

[0011] As a further optimization of this utility model, an opening is provided at the middle position inside the base and at the middle position at the top of the U-shaped mounting bracket. The opening inside the base fits into the outside of the collection tube, and the opening inside the U-shaped mounting bracket cooperates with the outside of the second servo motor.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The structural design of the adjustment component of this utility model allows operators to easily control and adjust the sampling depth inside the sampling cylinder, facilitating sampling operations at different soil depths, ensuring the accuracy of subsequent sampling adjustments, and making it easy for beginners to use without relying on operational experience to control the sampling depth.

[0014] 2. This utility model, through the structural design of the drive component, can easily complete the driving sampling work of the sampling tube without the need for the operator to manually press the sampling tube to sample. This ensures the convenience and intelligence of the operator's driving sampling in the later stage, reduces the physical consumption of the operator, and, together with the structural design of the limiting component, allows the operator to easily and intuitively view the sampling depth of the sampling tube, ensuring the flexibility and practicality of later adjustment and use.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 , Figure 2As shown, an adjustable-depth farmland soil sampler includes a mounting assembly 1. The structural design of the mounting assembly 1 facilitates the subsequent fixing and installation of components. The mounting assembly 1 includes a base 100, with a U-shaped mounting bracket 101 fixed to both sides of the base 100. Openings are provided at the center of the interior of the base 100 and at the center of the top of the U-shaped mounting bracket 101 to facilitate the insertion and removal of components. U-shaped handles are fixedly installed on both sides of the U-shaped mounting bracket 101, facilitating the handling and transport of the soil sampler. A drive assembly 2, located inside the U-shaped mounting bracket 101, is rotatably mounted on one side of the top of the base 100. On the other side of the unit, a limiting component 4 is fixedly installed to cooperate with the drive component 2. The structural design of the drive component 2 facilitates the automatic insertion and collection of soil in the later stage. In addition, the structural design of the limiting component 4 can also facilitate the limiting and prompting of the soil collection and insertion depth. The drive component 2 includes a drive screw 200 rotatably installed on one side of the top of the base 100. A servo motor 201 is fixedly inserted through one side of the top of the U-shaped mounting bracket 101. A coupling is fixedly installed on the output end of the servo motor 201. The bottom of the coupling is fixedly connected to the top of the drive screw 200, which facilitates the rotation of the drive screw 200 in the later stage. The servo motor 201 is a Siemens SIMOTICS. The S-1FL6 drive screw 200 has a threaded external fitting with a collection cylinder 202 that slides through to the center of the base 100. The collection cylinder 202 slides into the opening at the center of the base 100, facilitating scraping of the soil outside the collection cylinder 202 while it moves up and down within the opening. Limit sleeves are fixedly fitted to the top of the outer side of the collection cylinder 202, and connecting plates are fixedly installed on both sides of the limit sleeves. One connecting plate is threaded onto the outside of the drive screw 200. This threaded engagement between the connecting plate and the drive screw 200 allows the drive screw 200 to scrape the soil around the collection cylinder 202 and its components. The driving operation includes a limit assembly 4 consisting of a threaded rod 401 fixedly installed on the other side of the top of the base 100 and connected to the top of the U-shaped mounting bracket 101. Another connecting plate outside the collection sleeve 200 is slidably fitted onto the outside of the threaded rod 401. Then, through the cooperation of another connecting plate with the threaded rod 401, the movement of the collection sleeve 200 and its components can be conveniently limited and connected to improve the stability of the subsequent displacement drive of the collection sleeve 200. The threaded rod 401 is threadedly fitted with an internal threaded sleeve block 400 that cooperates with the collection cylinder 202. Multiple actuating blocks are fixedly installed on the outside of the internal threaded sleeve block 400 to facilitate the rotation operation of the internal threaded sleeve block 400 by the operator.

[0022] like Figure 2 , Figure 3 As shown, an adjustment component 3 is fixedly installed on the inner top of the sampling sleeve 200, located outside the U-shaped mounting bracket 101. Through the installation design of the adjustment component 3, the depth of subsequent sampling inside the sampling sleeve 200 can be easily adjusted, facilitating subsequent soil sampling operations at different depths. The adjustment component 3 includes an adjustment block 302 slidably located at the bottom of the sampling cylinder 202, and the adjustment block 302 is designed to fit snugly against the interior of the sampling sleeve 202. An adjustment screw 300, threaded through to the top of the sampling cylinder 202, is rotatably installed on the top of the adjustment block 302. Measuring rods, slidably penetrating to the sides of the inside of the sampling cylinder 202, are fixedly installed on both sides of the top of the adjustment block 302. The top of the two measuring rods 301 is jointly mounted with a servo motor 303 that is fixedly connected to the top of the adjusting screw 300. The model of the servo motor 303 is IMS20B-08M75B30C-2. The output end of the servo motor 303 is fixedly mounted with a coupling that is fixedly connected to the top of the adjusting screw 300. A U-shaped mounting bracket is fixedly mounted on the outside of the servo motor 303. The bottom of the U-shaped mounting bracket is fixedly connected to the top of the two measuring rods 301 and fits onto the outside of the adjusting screw 300. Later, when the servo motor 303 and the above components are lifted and moved, the rods can be removed through the opening at the top of the U-shaped mounting bracket 101.

[0023] It should be noted that, in the use of this adjustable-depth farmland soil sampler, the operator can first move the installation component 1 and above to the designated location, then connect the power supply. Then, the servo motor 203 rotates the adjusting screw 300. Through the threaded engagement between the adjusting screw 300 and the top of the collection cylinder 202, the adjusting block 302 and the measuring rod 301 can be pulled upwards inside the collection cylinder 202. The structural design of the measuring rod 301 allows the operator to easily and intuitively view the displacement height of the adjusting block 302 inside the collection cylinder 202, facilitating subsequent soil sampling at different depths and ensuring the versatility and convenience of subsequent sampling. After adjustment, the servo motor 201 drives the driving screw. The servo motor 201 moves the collection cylinder 202 and its components outside the threaded rod 401, and then drives the collection cylinder 202 to be inserted into the soil through the base 100, realizing automatic collection operation without the need for manual pressing by the operator. Later, when the servo motor 201 moves the drive screw 200 in the opposite direction, the collection cylinder 202 and its components can be pulled out. At the same time, in the process of inserting and closing the collection cylinder 202 and its components, the collection depth of the collection cylinder 202 and its components can be limited again by rotating the inner threaded sleeve 400 outside the threaded rod 401. This allows the operator to directly feel the insertion depth of the collection cylinder 202, increasing the flexibility and convenience of the collector in later adjustment and use.

[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
