Description

Technical Field

[0002] In soil science research, agriculture, environmental engineering and other fields, soil sampling is an important step in obtaining soil properties, assessing soil pollution status, and guiding agricultural farming.

[0003] At present, soil sampling methods mostly rely on manual handheld ring knives for digging and sampling. In actual operation, manual handheld ring knives for soil sampling often require a lot of physical effort, especially when facing hard or sticky soil. The operator needs to spend a lot of effort to insert the ring knife into the soil and completely remove the soil sample. After the sampling is completed, it is also extremely inconvenient to remove the soil sample from the ring knife. Due to the large friction between the soil and the inner wall of the ring knife, and the fact that the soil may have a certain degree of viscosity and moisture, it becomes very difficult to manually push the soil out of the ring knife. This step often requires the use of additional tools or repeated knocking of the ring knife, which not only increases the complexity and time cost of the operation, but may also cause a certain degree of damage to the soil sample, affecting the accuracy of subsequent analysis results.

[0004] In view of the above problems, a sampling device for soil testing is now designed. Utility Model Content

DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The embodiment of the present application provides a sampling device for soil testing, which can solve the problem that the ring knife used for soil sampling in the related art is relatively laborious to operate and it is inconvenient to remove the soil inside the ring knife.

[0032] See also Figure 1-Figure 3A soil testing sampling device includes a support 1 with a support table 2 slidingly arranged thereon, a driving member 3 arranged on the support 1 for driving the support table 2 to ascend and descend, a cutting ring 4 rotatably arranged at the bottom of the support table 2 for soil sampling, a rotating member 5 arranged on the support table 2 for driving the cutting ring 4 to rotate, a pushing member 6 slidingly arranged in the cutting ring 4 for pushing the sampled soil out of the cutting ring 4, the pushing member 6 including a pushing disc 61 with two opposite circular rods 62 arranged thereon, the pushing disc 61 being adapted to the inner diameter of the cutting ring 4, the cutting ring 4 being provided with two sliding holes 63 adapted to the circular rods 62 and arranged opposite to each other, and the circular rods 62 penetrating the sliding holes 63 at one end.

[0033] By operating the driving member 3, the support table 2 can ascend and descend on the support 1. This action enables the cutting ring 4 to be accurately positioned according to the needs of different soil depths, preparing for sampling.

[0034] When the support table 2 descends to a predetermined depth, the rotating member 5 starts to work. The rotating member 5 drives the cutting ring 4 to start rotating, and the rotating cutting ring 4 can reduce the friction with the soil, helping the cutting ring to cut into the soil more easily and take out the complete soil sample.

[0035] After the cutting ring 4 completes sampling and lifts back to the original position, the pushing member 6 starts to work. The pushing disc 61 of the pushing member 6 closely fits the inner diameter of the cutting ring 4, pushes the two circular rods 62 downward, drives the pushing disc 61 to move along the axial direction of the cutting ring 4, and at the same time, the circular rods 62 on the pushing disc 61 slide in the sliding holes 63 on the cutting ring 4, playing a guiding and stabilizing role. With the forward movement of the pushing disc 61, it gradually pushes the soil sample inside the cutting ring 4 out, completing the sampling process.

[0036] Through the automatic lifting and rotating mechanism, the physical burden of the operator is greatly reduced, and the sampling efficiency is improved. At the same time, the rotating cutting ring can cut into the soil more easily, reducing the sampling time. Through the cooperation of the cutting ring 4 and the pushing member 6, the integrity of the soil sample during sampling and pushing out is ensured, reducing the risk of sample damage, and at the same time, the operation is more convenient, improving the work efficiency.

[0037] The whole device has compact structure and simple operation. The operator only needs to realize the whole process of sampling and soil pushing out through simple control, without complex operation steps or additional tools.

[0038] By adjusting the lifting height of the support table 2 and the rotating speed of the cutting ring 4, the device can adapt to the sampling needs of different depths and hardness of soil, and has wide applicability.

[0039] In this embodiment, the bracket 1 is L-shaped, a handle 7 is provided on the bracket 1, and two ground nails 8 are threadedly connected to each other at the bottom of the bracket 1.

[0040] The bracket 1 in this embodiment is L-shaped and has sufficient strength and stability to support the entire sampling device.

[0041] The presence of the handle 7 enables the operator to easily move and fix the entire sampling device, making it convenient to perform soil sampling at different locations.

[0042] The ground spike 8 is usually made of a hard metal material, such as steel or iron, and has a sharp tip and a wide base so that it can be easily inserted into the soil and firmly fixed. The ground spike 8 is connected to the bottom of the bracket 1 through a thread, and the operator can remove the ground spike 8 from the bracket 1 by rotating it.

[0043] In one embodiment, the support platform 2 includes a slide 21 and a support plate 22 connected to each other, a slider 23 is arranged opposite to the side of the slide 21 away from the support plate 22, two slide rails 24 are arranged opposite to each other on the bracket 1, and the slider 23 slides with the slide rails 24; the support plate 22 is L-shaped.

[0044] The support platform 2 is composed of two main parts: a slide 21 and a support plate 22. The two parts are connected into a whole by bolts.

[0045] The slide rail 24 forms a sliding fit with the slider 23 on the slide 21. When the driving member 3 works, it drives the slide 21 and the support plate 22 and the ring cutter 4 thereon to slide up and down along the slide rail 24, thereby realizing the lifting function of the support platform 2.

[0046] The support plate 22 is L-shaped. The L-shaped structure provides a larger support area, which helps to disperse the force generated by the ring knife 4 when sampling and protect the bracket 1 from damage. Secondly, the L-shaped structure also provides a more stable installation platform for the rotating member 5 and other components that may be installed on the support plate 22.

[0047] It should be noted that the drive member 3 in this embodiment includes: a reducer 31 mounted on the bracket 1; a drive motor 32 mounted on the reducer 31; a screw 33 rotatably mounted on the bracket 1; and a transmission block 34 threadedly connected to the outer wall of the screw 33. The output shaft of the drive motor 32 is connected to the input shaft of the reducer 31, the output shaft of the reducer 31 is connected to one end of the screw 33, and the transmission block 34 is connected to the slide 21. The transmission block 34 has threads internally formed therein that mate with the screw 33.

[0048] A groove is formed on one side of the bracket 1 close to the slide 21 . The groove is located between the two slide rails 24 , and the screw rod is rotatably arranged inside the groove.

[0049] The screw rod 33 is a key component of power transmission. One end of the screw rod 33 is connected to the output shaft of the reducer 31. Through the deceleration and torque increase of the reducer 31, the power of the drive motor 32 is transmitted to the screw rod 33 to make it rotate.

[0050] The transmission block 34 is threadedly connected to the outer wall of the screw rod 33. When the screw rod 33 rotates, the transmission block 34 moves along the axial direction of the screw rod 33. The transmission block 34 is connected to the slide 21, so when the transmission block 34 moves, it drives the slide 21 and the support plate 22 and the ring knife 4 thereon to rise and fall together.

[0051] A groove is formed on one side of the bracket 1 close to the slide 21 . The groove is located between the two slide rails 24 and is used to accommodate the screw rod 33 and provide a stable rotation environment for the screw rod 33 .

[0052] When drive motor 1 32 is activated, it transmits power to screw rod 33 via reducer 1 31, causing it to rotate. Because transmission block 34 is threadedly connected to the outer wall of screw rod 33, as screw rod 33 rotates, transmission block 34 moves axially along the axis of screw rod 33. Because transmission block 34 is connected to slide 21, slide 21, its support plate 22, and ring cutter 4 rise and fall accordingly, adjusting the depth of soil sampling.

[0053] It can be understood that the ring knife 4 is cylindrical, has a cavity for soil sampling inside, and has an open bottom.

[0054] The ring knife 4 is cylindrical, and this shape can provide a stable and continuous space to accommodate the sampled soil.

[0055] The bottom of the ring cutter 4 is open, which is to facilitate the insertion of the ring cutter into the soil and cut the soil and collect it into the cavity inside the ring cutter by rotating and pressing down.

[0056] In one embodiment, the rotating member 5 includes a reducer 2 and a drive motor 2 provided on the support plate 22. The output shaft of the drive motor 2 is connected to the input shaft of the reducer 2, and the output shaft of the reducer 2 is connected to the ring cutter 4. The support plate 22 is provided with a mounting hole for accommodating the output shaft of the reducer 2.

[0057] The support plate 22 is provided with a mounting hole for accommodating the second output shaft of the reducer. The mounting hole needs to ensure that the second output shaft of the reducer can be accurately and stably installed therein and can smoothly transmit power to the ring cutter 4.

[0058] When drive motor 2 starts, it transmits power to ring cutter 4 via reducer 2. Reducer 2's function is to reduce the speed and increase the torque to accommodate the force and speed required for ring cutter 4 to rotate in the soil. Ring cutter 4 begins to rotate after receiving power, cutting the soil with its sharp edge and collecting it into the cavity inside. The design of rotating member 5 allows the operator to easily control the sampling process of ring cutter 4 by controlling the start and stop and speed of drive motor 2.

[0059] Preferably, Figure 4 As shown, two mounting brackets 9 are relatively arranged on the ring cutter 4 in this embodiment, and an electric push rod 10 is arranged at the bottom of the mounting bracket 9. The bottom end of the piston rod of the electric push rod 10 is connected to the round rod 62.

[0060] When sampling is required, the electric push rod 10 is in a retracted state. This means that the piston rod of the electric push rod 10 is completely or mostly retracted, so that it does not exert downward pressure on the push plate 61. The push plate 61 is now in its initial position, that is, it is located above the internal cavity of the ring knife 4 and will not interfere with the sampling operation of the ring knife 4.

[0061] Once sampling is completed, electric push rod 10 begins to extend. Along with the extension of electric push rod 10 piston rods, it applies downward pressure to push material tray 61 through round rod 62.

[0062] The pushing plate 61 descends under the promotion of the electric push rod 10, gradually approaches and contacts the soil sample inside the ring cutter 4. As the pushing plate 61 continues to descend, it begins to push the soil sample out of the cavity of the ring cutter 4.

[0063] When the soil sample is completely pushed out, the electric push rod 10 can stop extending and remain at the current position, or retract slightly as needed to avoid causing excessive pressure on the pushing plate 61.

[0064] This design enables the soil testing sampling device to automatically and effectively push the soil sample out of the ring knife 4 after sampling is completed, thereby improving work efficiency and reducing the need for manual intervention.
