Description

Technical Field

[0001] This utility model belongs to, but is not limited to, the field of soil sampling technology, and particularly relates to a device capable of taking soil samples and stockpiled materials at different depths. Background Technology

[0002] Agricultural cash crops, as a crucial research area connecting cash crops and agricultural land use, have received significant attention globally. Through scientific research and optimized utilization of land resources, the development and cultivation of agricultural cash crops can effectively improve land use efficiency and promote regional economic development. However, accurately understanding the soil characteristics of the development site is paramount in the development of agricultural cash crops, requiring efficient soil sampling and testing technologies. Existing soil sampling and stratification methods suffer from low efficiency and insufficient accuracy, becoming a key bottleneck affecting the quality of agricultural cash crop development.

[0003] The current common method for soil sampling is to press a sampling cylinder into the ground, allowing soil to fill the bottom of the cylinder layer by layer, forming a soil sample column corresponding to the sampling depth. This method is simple and easy to implement, but it has significant problems in the subsequent stratification of the soil sample. The conventional method usually involves removing the soil sample from the sampling cylinder, measuring its length, and manually cutting it into layers based on the measurement results. This operation relies on manual labor and is inefficient and complex. More importantly, during the extraction process, the soil sample is easily broken, damaged, or even mixed, leading to decreased stratification accuracy and affecting the accuracy of subsequent soil composition analysis results.

[0004] Furthermore, during the process of pressing the sampling cylinder into the ground, the soil sample is subjected to compression by the cylinder wall, causing soil at different depths within the sample column to be compressed or even displaced. This compression effect is particularly pronounced in soft or moist soils, making it difficult for the soil column structure to maintain its original state. Due to this compression, the distribution of the soil sample within the cylinder cannot accurately reflect the true depth of each layer of the original soil. This deviation further increases the difficulty of stratification and affects the accuracy of depth-related measurements such as soil nutrients, pH, and microbial community structure.

[0005] Based on the above analysis, current soil sample stratification methods face the following main problems in the development of agricultural cash crops:

[0006] 1. Low layering efficiency: Traditional manual measurement and cutting layering requires a lot of manual operation, which is time-consuming and not suitable for rapid detection needs of large areas and multiple points.

[0007] 2. Sample fragmentation: Soil samples are prone to fragmentation or mixing during extraction and cutting, affecting sample integrity and the reliability of testing.

[0008] 3. Difficulty in determining depth: Due to the squeezing effect of the sampling tube, the depth of different layers in the soil sample column is inconsistent with the actual sampling location, resulting in a large error in stratification positioning. Utility Model Content

[0009] In view of the problems existing in the prior art, this utility model provides a device that can collect soil samples and stockpiles at different depths.

[0010] This utility model is implemented as follows: a device capable of taking soil samples and material samples at different depths includes a shovel tail, a shovel handle, a chute, a push button, a shovel head, a sampling cover, and a slot. The shovel handle is provided with a straight shovel tail, the shovel handle is connected to the shovel head, the shovel handle is provided with a chute and a push button, the top of the shovel head is provided with a sampling cover that can move back and forth, and the side of the shovel head is provided with a slot.

[0011] Furthermore, the shovel handle has a multi-section detachable structure, which can be disassembled and assembled according to actual length requirements.

[0012] Furthermore, a scale is installed on the shovel handle for depth measurement.

[0013] Furthermore, a scale is provided on the side of the shovel head (side body) to accurately control the depth of the shovel head inserted into the soil.

[0014] Furthermore, the push button is connected to the sliding structure controlling the sampling cover. When the shovel head is inserted into the appropriate position, pushing the push button allows it to slide in the groove, causing the shovel head to penetrate the soil layer. The sampling cover head then moves down and closes with the bottom of the shovel head, separating the soil sample from the surrounding soil. Additionally, a baffle can be installed in the shovel head to control the sampling thickness, and the baffle is secured in a slot.

[0015] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this utility model are as follows:

[0016] This utility model features a multi-section, detachable shovel handle, allowing for length adjustment to suit specific working needs. It includes a slot for precisely controlling sampling thickness by placing a baffle within the shovel head and engaging it in the slot. A scale is also provided on the shovel handle for depth measurement. A scale is further integrated into the side of the shovel head (side body) to accurately control the depth to which the shovel head inserts into the soil.

[0017] Traditional soil sampling devices have significant shortcomings in controlling sampling depth and thickness. Uneven depth or thickness of the collected soil samples often affects the accuracy of analysis results. This invention addresses this issue by incorporating a multi-section detachable structure on the shovel handle, equipped with a scale, allowing the operator to precisely adjust the sampling depth as needed. Simultaneously, the shovel head features baffles and slots, effectively limiting the thickness of each sample, ensuring the accuracy of soil layer thickness, and significantly improving sampling consistency.

[0018] Traditional sampling equipment is bulky and lacks precise control mechanisms, resulting in low sampling efficiency and cumbersome operation, especially in complex soil environments where repeated operations are required. This invention, through an innovative design combining a push button and a sliding groove, allows the operator to easily slide and control the sampling cover without additional adjustment of the sampling tool. This design not only reduces the operator's workload but also significantly shortens the sampling process time, improving overall work efficiency. Furthermore, this invention is compact, lightweight, and easily disassembled and carried.

[0019] Sample contamination during sampling is a common problem with traditional devices, especially when collecting samples from deeper soil layers, where external soil can easily mix with the target sample. This invention addresses this issue with a sampling cap and slot design that utilizes a sliding separation mechanism. When the shovel head is inserted into the appropriate position, pushing the push button allows it to slide in the slot, causing the shovel head to penetrate the soil layer. The shovel head then slides down and closes with the bottom of the shovel head, separating the soil sample from the external soil. This effectively isolates the sampled soil from the external environment, preventing contamination or mixing, thus ensuring the purity of the collected sample and providing a reliable guarantee for subsequent experimental analysis.

[0020] Through the ingenious design of the baffle and slot in the shovel head, this invention allows for adjustment of the sliding position of the sampling cap according to sampling needs, thereby precisely limiting the sampling thickness. Combined with the scale on the shovel handle and the multi-section adjustable structure, the operator can accurately sample at different soil depths, significantly improving the depth and thickness control capabilities that traditional equipment cannot achieve, ensuring the quality of sample collection. A scale is also provided on the side (side body) of the shovel head, allowing for accurate control of the depth to which the shovel head inserts into the soil, further improving the consistency of sample collection.

[0021] The combination of the push button and the sliding groove design makes the sliding control of the sampling cover extremely convenient. Operators do not need complex adjustments; simply pushing the push button achieves soil sample stratification and isolation. Compared to traditional devices, this optimized design reduces operational steps and errors, significantly improving the convenience and efficiency of soil sampling and meeting the needs of large-scale sampling.

[0022] By combining a sampling cap and a slot, this invention successfully achieves strict isolation between soil samples and external soil. The baffle further ensures the consistency of sampling thickness for each sample, resulting in higher sample purity and avoiding the inaccurate analysis caused by contamination or mixing in traditional sampling. This design not only improves sampling accuracy but also makes soil analysis results more scientific and reliable, providing important technical support for the precision development of agricultural and economic crops.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0033] like Figure 1 As shown in the figure, the device provided by this utility model embodiment, which is capable of taking soil and material samples at different depths, includes a shovel tail 1, a shovel handle 2, a chute 4, a push button 3, a shovel head 7, a sampling cover 5, and a slot 6. The shovel handle 2 is provided with a straight shovel tail 1 at the end. The shovel handle 2 is connected to the shovel head 7. The shovel handle 2 is provided with a chute 4 and a push button 3. The top of the shovel head 7 is provided with a sampling cover 5 that can move back and forth. The side of the shovel head 7 is provided with a slot 6.

[0034] The handle 2 is a multi-section detachable structure, which can be disassembled and assembled according to the actual length requirements.

[0035] The handle 2 is equipped with a scale for depth measurement.

[0036] like Figure 4As shown, a scale 8 is provided on the side (side body) of the shovel head 7, which can be used to measure the depth of the shovel head inserted into soil samples.

[0037] like Figure 2 As shown, the push button 3 is connected to the sliding structure of the control sampling cover 5. When the shovel head 7 is inserted into the appropriate position, the push button is pushed to slide in the groove, so that after the shovel head 7 is inserted into the soil layer, the head of the sampling cover 5 moves down and closes with the bottom of the shovel head 7, separating the soil sample from the external soil.

[0038] Before operation, the sampling thickness needs to be preset. The sampling cap 5 is fixed in a specific position by a slot, with each position corresponding to a different sampling thickness. This design allows operators to flexibly select the analysis thickness of the soil sample according to actual needs, which not only improves the sampling accuracy but also ensures the reliable separation and effective preservation of soil samples at different depths, providing accurate samples for subsequent soil analysis.

[0039] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a traction closing device is designed on the side of the shovel head 7. This device can be controlled by a push button 3 through an internal mechanical structure (such as a linkage, rope, or slide rail system). The traction closing device includes a cable fixing clamp 19, a cable 10, a cable fixing clamp 211, and a shovel head interlayer 12; the push button 3 is connected to the cable fixing clamp 19 and the cable fixing clamp 211 through the cable 10; the pull rod moves backward, pulling the cable 10 to drive the sampling cover 5, thus closing the shovel head. The cable device is installed inside the shovel head interlayer 12.

[0040] When the shovel head 7 is inserted into the soil to the predetermined depth, the user pushes the push button 3, the traction closing device is activated, and the front end of the sampling cover 5 is pulled downward to close tightly with the bottom edge of the shovel head 7, thereby separating the soil sample inside the shovel head from the external soil sample and sealing the soil sample inside the shovel head.

[0041] The traction closure device should be designed to be robust and flexible enough to ensure reliable operation under various soil conditions.

[0042] The slot 6 can be designed to be adjustable, allowing the user to adjust the position of the sampling cover 5 before sampling, according to the required sampling thickness.

[0043] The card slot 6 has different settings, corresponding to different sampling thicknesses, such as 1cm-10cm, which is the internal height of the sampling cover to the bottom of the shovel head.

[0044] A tight locking mechanism should be designed between the sampling cover 5 and the slot 6 to ensure that the sampling cover 5 will not move accidentally during the sampling process.

[0045] A scale is added to the side of the shovel head 7, which works in conjunction with the scale on the shovel handle 2 to achieve precise sampling from multiple dimensions (depth and width).

[0046] This will help users more accurately determine the position of the shovel head 7 in the soil, as well as the point of closure between the sampling cover 5 and the bottom leading edge of the shovel head 7.

[0047] The slide 4 should be designed to be wide and smooth enough to ensure that the front edge of the sampling cover 5 slides smoothly and unobstructed in the vertical direction.

[0048] The inside of the groove 4 can be coated with grease or fitted with a slide rail to reduce friction and extend service life.

[0049] The end of the chute 4 should be designed with a stop device to prevent the sampling cover 5 from falling off during movement.

[0050] The entire device (including the shovel tail 1, shovel handle 2, shovel head 7, etc.) should be made of high-strength materials to ensure that it can withstand the pressure and friction of the soil during the sampling process.

[0051] The multi-section detachable structure of the shovel handle 2 should be designed with a tight connection mechanism to ensure that it does not loosen or fall off during sampling.

[0052] like Figure 3 As shown, a baffle can be set in the shovel head 7 to control the sampling thickness, and the baffle is locked in the slot 6.

[0053] 1. Sampling cap adjustment function

[0054] This device uses a shovel head 7 to sample soil layers, and the sampling cover 5 is inserted into the corresponding position of the slot 6 to precisely control the thickness of the sample collected.

[0055] 2. Sample collection process

[0056] The straight-lined shovel tail 1 at the end of the shovel handle 2 allows for easy force to drive the shovel head into the soil. After the shovel head 7 is inserted into the soil, the operator can control the sampling depth of the shovel head 7 using the markings on its side, ensuring that the shovel head 7 is inserted to the predetermined soil depth. 3. Depth and Thickness Control

[0057] The shovel handle 2 is equipped with a scale, which allows operators to accurately measure the depth of the soil layer during sampling. The multi-section, detachable shovel handle 2 allows for adjustment of the handle length as needed, facilitating sampling at different soil depths.

[0058] 4. Card slot and baffle design

[0059] Using this prototype tool, soil samples were taken at different depths in the field. The depth and thickness of the samples can be precisely controlled, and the relative consistency of soil samples taken from different locations in terms of spatial position can be achieved, reducing systematic errors and facilitating the smooth conduct of subsequent experimental work.
