Abstract
Description
Technical Field
[0001] This utility model relates to soil sampling, specifically to an agricultural soil sampling device. Background Technology
[0002] In agriculture, soil sampling is a crucial task, providing fundamental samples for soil fertility assessment, soil composition analysis, and crop growth research. However, traditional soil sampling equipment has many limitations in practical applications.
[0003] On the one hand, different users face challenges due to individual differences when operating sampling equipment. Users vary considerably in height; taller or shorter users may find it difficult to find a comfortable and efficient operating posture due to the fixed structure of traditional sampling equipment. For example, shorter users may have difficulty reaching higher operating parts of the traditional equipment, while taller users may bend over excessively due to lower operating parts, leading to inconvenience and fatigue. Simultaneously, users differ in strength, which is more pronounced when dealing with different soil textures. Users with less strength may struggle to apply sufficient force to insert the sampling tube into the soil when it is hard, while stronger users may over-insert the sampling tube into the soil when operating traditional equipment in softer soil due to a lack of precise force control, affecting sampling accuracy.
[0004] Therefore, there is an urgent need for a better agricultural soil sampling device on the market. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide an agricultural soil sampling device.
[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is an agricultural soil sampling device: including a central core rod, a handle is provided at the upper part of the central core rod, and a sampling tube is provided at the lower part of the central core rod;
[0007] The central core rod is provided with a limiting groove, and the number of the limiting grooves is several and they are evenly distributed from the upper part of the central core rod to the lower part of the central core rod.
[0008] It also includes an adjustable pedal mechanism, which includes a central core sliding sleeve that is fitted onto and slides on the central core rod.
[0009] The lower part of the outer wall of the central core sliding sleeve is rotatably provided with a foot pedal through a hinge shaft connection. The foot pedal extends forward, and a limiting plate is provided at the lower part of the foot pedal. The lower end of the limiting plate extends into a limiting groove provided on the central core rod.
[0010] As an improvement, an auxiliary frame is provided on the rear side of the pedal, and a tension spring is provided on the auxiliary frame. The other end of the tension spring extends to the upper part of the outer wall of the central core sliding sleeve and is fixedly connected to the upper part of the outer wall of the central core sliding sleeve.
[0011] As an improvement, the lower end of the limiting plate extends downward toward the central core sliding sleeve.
[0012] As an improvement, a guide bar is provided on the central core rod.
[0013] As an improvement, the central core sliding sleeve is provided with a long sliding groove, which slides in conjunction with the guide strip.
[0014] As an improvement, the guide bar extends from the upper part of the central core rod to the lower part of the central core rod.
[0015] As an improvement, the extension direction of the guide strip is parallel to the extension direction of the central core rod.
[0016] As an improvement, the sampling tube has its opening facing downwards.
[0017] As an improvement, the extension direction of the sampling tube and the extension direction of the central core rod are on the same straight line.
[0018] The advantages of this invention compared to existing technologies are as follows: Adjustable foot pedal and pedal position: In actual agricultural soil sampling, different user heights, strengths, and soil conditions may all require different operation of the sampling equipment. This device allows for adjustment of the foot pedal and pedal position, a feature that greatly improves its versatility. For example, taller users may need to adjust the pedal to a higher position for more comfortable use, while in harder soil conditions, adjusting the adjustable foot pedal to a suitable position can more effectively transmit the stepping force, thus facilitating use and footing.
[0019] Easy-to-adjust upward-moving foot pedal and foot plate: The convenience of the upward-moving adjustable foot pedal and foot plate is a significant advantage of this equipment. During sampling, as the sampling depth increases or the soil texture changes, the position of the foot plate may need to be adjusted. The convenient upward-moving mechanism allows users to quickly adjust according to the actual situation, ensuring that the adjustable foot pedal and foot plate are in a reasonable and convenient position for use.
[0020] Easy to operate: The overall structure of the equipment is simple and clear, and the connection and cooperation between the various components are easy to understand and operate. For example, the layout of components such as the central core rod, sampling cylinder, and adjustable pedal mechanism is reasonable, and users can master the operation method without complicated training.
[0021] The ergonomic design of gripping the handles with both hands and simultaneously pressing the pedals with one foot allows users to apply force naturally. Furthermore, adjusting the adjustable pedal mechanism and pedal position involves simple steps; actions such as rotating the pedals and sliding the central core sliding sleeve require no complex skills, further highlighting the equipment's ease of operation.

[0032] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] Referring to the accompanying drawings, an agricultural soil sampling device includes a central core rod 1, with a handle 2 at the upper part of the central core rod 1 and a sampling cylinder 3 at the lower part of the central core rod 1. The opening of the sampling cylinder 3 faces downward, and the extension direction of the sampling cylinder 3 and the extension direction of the central core rod 1 are on the same straight line.
[0034] The central core rod 1 is provided with a guide strip 4, which extends from the upper part of the central core rod 1 to the lower part of the central core rod 1. The extension direction of the guide strip 4 is parallel to the extension direction of the central core rod 1. The central core rod 1 is provided with a limiting groove 5, which is a plurality of grooves and is evenly distributed from the upper part of the central core rod 1 to the lower part of the central core rod 1.
[0035] It also includes an adjustable pedal mechanism 6, which includes a central core sliding sleeve 7, which is fitted onto the central core rod 1 and slides on the central core rod 1; the central core sliding sleeve 7 is provided with a long sliding groove 8, which slides in conjunction with the guide strip 4.
[0036] A foot pedal 9 is rotatably mounted on the lower outer wall of the central core sliding sleeve 7 via a hinge shaft. The foot pedal 9 extends forward, and a limiting plate 10 is provided at the lower part of the foot pedal 9. The lower end of the limiting plate 10 extends downward toward the central core sliding sleeve 7 and extends into a limiting groove 5 provided on the central core rod 1. An auxiliary frame 11 is provided on the rear side of the foot pedal 9, and a tension spring 12 is provided on the auxiliary frame 11. The other end of the tension spring 12 extends toward the upper part of the outer wall of the central core sliding sleeve 7 and is fixedly connected to the upper part of the outer wall of the central core sliding sleeve 7. The tension spring 12 provides a downward rotational force to the foot pedal 9 to ensure the stability of the lower end of the limiting plate 10 extending into the limiting groove 5 provided on the central core rod 1.
[0037] In the initial state, the user first observes the adjustable pedal mechanism 6 and will find that the central core sliding sleeve 7 is positioned relatively low on the central core rod 1. This is to facilitate subsequent pedaling operations, allowing the user to exert force more easily. At this time, the limiting plate 10 is firmly locked in the corresponding limiting groove 5, and the entire device is in a stable state.
[0038] Next, the user holds the handles 2 on the upper part of the central core rod 1 with both hands, and aligns the sampling tube 3 vertically with the ground location where sampling is required, ensuring that the sampling tube 3 is in good contact with the ground and is not tilted. At the same time, the user lifts one foot and places it on the pedal 9 of the adjustable pedal mechanism 6, ready to perform the pedaling action.
[0039] The user slowly and forcefully presses down on pedal 9. The downward pressure on pedal 9 causes the central core sliding sleeve 7 to move downward as well. The central core sliding sleeve 7, due to the sliding engagement between the elongated sliding groove 8 and the guide bar 4, as well as the assistance of the tension spring 12 in the downward rotation of pedal 9, improves stability and thus steadily presses the sampling cylinder 3 below into the ground, initiating the soil sampling process.
[0040] Once the sampling cylinder 3 has penetrated to a certain depth into the ground, if further deepening of the sampling is required, the user needs to adjust the position of the adjustable foot pedal 6. At this time, the user presses their foot against the underside of the foot pedal 9 and then slowly lifts their foot upwards, causing the foot pedal 9 to rotate upwards. During the upward rotation of the foot pedal 9, the tension spring 12 on its rear auxiliary frame 11 is gradually stretched, generating a pulling force to resist the upward rotation. Simultaneously, the lower end of the limiting plate 10 at the bottom of the foot pedal 9 gradually disengages from the limiting groove 5 on the central core rod 1 as the foot pedal 9 rotates.
[0041] As the pedal 9 continues to rotate upwards, the user applies an upward force, causing the pedal 9 to move the central core sliding sleeve 7 upwards along the central core rod 1. At this time, the elongated sliding groove 8 slides smoothly along the guide bar 4, ensuring the accuracy of the central core sliding sleeve 7's movement trajectory. The user can then move the central core sliding sleeve 7 to a suitable height as needed and slowly release their foot from the pedal 9.
[0042] After releasing the foot, the tension spring 12, which had previously been stretched and stored elastic potential energy, will quickly contract, causing the pedal 9 to rotate downwards. Under the tension of the tension spring 12, the lower end of the limiting plate 10 at the bottom of the pedal 9 will be precisely embedded again into the corresponding limiting groove 5 on the central core rod 1, so that the central core sliding sleeve 7 is re-fixed in a new and suitable position, ensuring the stability of the entire device at the new height, and making it convenient for the user to step on it again to carry out the next soil sampling operation.
[0043] Users can continuously cycle through the above steps, adjusting the position of the adjustable stepping mechanism 6 each time to allow the sampling tube 3 to gradually penetrate deeper into the soil until the specified sampling depth is reached, thus completing high-quality soil sampling.
[0044] Through this detailed and orderly operating procedure, users can make full use of the design advantages of this agricultural soil sampling equipment to efficiently and accurately obtain soil samples at the required depth, providing strong support for subsequent agricultural soil analysis and other work.
[0045] Adjusting the position of the adjustable foot pedal 6 and the foot pedal: In actual agricultural soil sampling work, different users' heights, strengths, and soil conditions may all require different operation of the sampling equipment. This device allows for adjustment of the position of the adjustable foot pedal 6 and the foot pedal 9, a feature that greatly improves the device's versatility. For example, taller users may need to adjust the foot pedal 9 to a higher position for more comfortable use, while in harder soil conditions, adjusting the adjustable foot pedal 6 to a suitable position can more effectively transmit the stepping force, thus facilitating use and making stepping easier.
[0046] The ease of upward-moving adjustable foot pedal mechanism 6 and foot pedal 9 is a significant advantage of this device. During sampling, as sampling depth increases or soil texture changes, the position of the foot pedal 9 may need adjustment. The convenient upward-moving mechanism allows users to quickly adjust according to the actual situation, ensuring that the adjustable foot pedal mechanism 6 and foot pedal 9 are in a reasonable and convenient position for use.
[0047] For example, when the sampling tube 3 needs to penetrate deeper into the soil layer, the user can easily move the adjustable foot pedal 6 and foot pedal 9 upwards to change the point of application and magnitude of the force to adapt to deeper sampling needs. This feature not only improves sampling efficiency but also reduces user fatigue.
[0048] Easy to operate: The overall structure of the equipment is simple and clear, and the connection and cooperation between the various components are easy to understand and operate. For example, the layout of components such as the central core rod 1, sampling cylinder 3, and adjustable pedal mechanism 6 is reasonable, and users can master the operation method without complicated training.
[0049] The operation method of holding the handles 2 with both hands and stepping on the pedal 9 with one foot is ergonomic, allowing the user to apply force naturally. Moreover, the operation steps involved in adjusting the position of the adjustable pedal mechanism 6 and the pedal 9 are simple. Actions such as rotating the pedal 9 and sliding the central core sliding sleeve 7 do not require complicated skills, further demonstrating the ease of operation of the equipment.
[0050] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
