Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically to an adjustable soil sampling device. Background Technology

[0002] To analyze the metal content in soil, metal sampling tools should be avoided. When sampling in the field, due to the spatial heterogeneity of soil distribution, multiple samples should be taken from each plot and then mixed into a single composite sample. This ensures a better representation of the soil properties of the sampling area. Before sampling, the soil profile should be prepared and cleaned, removing the topsoil, and then samples should be taken layer by layer from top to bottom, starting from the central, representative areas.

[0003] For example, 202323009176.7 proposes an adjustable-depth soil sampling device. This adjustable-depth soil sampling device allows the upper layer of soil to be discharged under the combined action of the lower extension rod and the baffle, and then the baffle can be opened under the push of the third electric push rod, so that the sampler can be inserted into the soil layer at the corresponding depth.

[0004] Since soil analysis requires collecting soil samples from different areas, which inevitably involves working on different terrains, traditional soil sampling devices are assembled to make them easy to carry. However, due to different terrain environments and different sampling personnel, it is necessary to adjust the height of the soil sampler to better exert force for soil collection. Therefore, an adjustable soil sampling device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable soil sampling device with advantages such as adjustable height and ease of use. It solves the problem that the height of the soil sampler needs to be adjusted to better exert force for soil sampling due to different terrain environments and different sampling personnel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable soil sampling device, comprising a sampling tube, a sleeve fixedly installed on the top of the sampling tube, a telescopic tube inserted into the top of the sleeve, a handle fixedly installed on the top of the telescopic tube, a push rod movably installed inside the telescopic tube, locking mechanisms provided on both the left and right sides of the sleeve, limit shafts fixedly installed on both the left and right sides of the telescopic tube, sliding grooves provided on both the left and right sides of the inner wall of the sleeve, and a push plate fixedly installed at the bottom end of the push rod;

[0007] The locking mechanism includes mounting grooves. Mounting grooves are provided on both the left and right sides of the sleeve. A support rod is movably installed inside the mounting groove. A limit sleeve is fixedly installed at the top of the support rod. A slot is provided on the opposite side of the two support rods. A pin is fixedly installed inside the two mounting grooves. A support spring is fixedly installed inside the slot.

[0008] Furthermore, the length of the telescopic cylinder is greater than or equal to the length of the sleeve, and the bottom end of the push rod extends through the handle, through the telescopic cylinder and the sleeve, and into the interior of the collection cylinder.

[0009] Furthermore, the limiting shafts are arranged at equal intervals on the left and right sides of the telescopic cylinder, and the portion of the limiting shaft inside the sleeve is placed inside the sliding groove.

[0010] Furthermore, the two support rods are located on the left and right sides of the telescopic cylinder, respectively, and the limiting sleeve is fitted onto the outer surface of the corresponding limiting shaft.

[0011] Furthermore, the pin is inserted into the interior of the slot, and the end of the support spring away from the inner wall of the slot is fixedly connected to the pin.

[0012] Furthermore, the lower part of the collection tube is an inclined surface, and the push plate is movably installed in a circular shape inside the collection tube, with the outer surface of the push plate fitting against the inside of the collection tube.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This invention uses a locking mechanism to adjust the height of the soil sampling device, making it easier to apply force when collecting soil in confined spaces. Furthermore, users can adjust the height of the soil sampling device according to their own height, ensuring an optimal user experience for workers of different heights. This solves the problem of needing to adjust the height of the soil sampler to better apply force when collecting soil due to varying terrain and personnel. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 An adjustable soil sampling device in this embodiment includes a sampling cylinder 1, a sleeve 2 fixedly installed on the top of the sampling cylinder 1, a telescopic cylinder 3 inserted into the top of the sleeve 2, a handle 4 fixedly installed on the top of the telescopic cylinder 3, a push rod 5 movably installed inside the telescopic cylinder 3, locking mechanisms 6 provided on both the left and right sides of the sleeve 2, limit shafts 7 fixedly installed on both the left and right sides of the telescopic cylinder 3, sliding grooves 8 opened on both the left and right sides of the inner wall of the sleeve 2, and a push plate 9 fixedly installed at the bottom end of the push rod 5.

[0022] The locking mechanism 6 includes a mounting groove 601. Mounting grooves 601 are provided on both the left and right sides of the sleeve 2. A support rod 602 is movably installed inside the mounting groove 601. A limit sleeve 603 is fixedly installed at the top of the support rod 602. A slot 604 is provided on the opposite side of the two support rods 602. A pin 605 is fixedly installed inside the two mounting grooves 601. A support spring 606 is fixedly installed inside the slot 604.

[0023] In this embodiment, the length of the telescopic cylinder 3 is designed to be smaller than the length of the sleeve 2, ensuring that the telescopic cylinder 3 can be inserted into the sleeve 2 for telescopic movement. The bottom end of the push rod 5 enters the handle 4 and passes through the telescopic cylinder 3 and the sleeve 2 in sequence to enter the collection cylinder 1. After collection is completed, the push rod 5 is pushed, and the push rod 5 moves downward. The push plate 9 moves downward inside the collection cylinder 1 and pushes out the soil collected inside the collection cylinder 1.

[0024] In this embodiment, the limiting shaft 7 is designed to be positioned on the left and right sides of the telescopic cylinder 3. The limiting shaft 7 can move inside the slide groove 8. The lower part of the collection cylinder 1 is an inclined surface. The push plate 9 is circularly and movably installed inside the collection cylinder 1, and the outer surface of the push plate 9 is in contact with the inside of the collection cylinder 1.

[0025] In this embodiment, two support rods 602 are located on the left and right sides of the telescopic cylinder 3, respectively. The limiting sleeve 603 is sleeved on the outer surface of the corresponding limiting shaft 7. The pin 605 is inserted into the inside of the slot 604. The end of the support spring 606 away from the inner wall of the slot 604 is fixedly connected to the pin 605.

[0026] In use, pull the two support rods 602 to both sides, causing them to move along the mounting groove 601. This stretches the support spring 606, and the support rods 602 move inside the slot 604. At this time, the two support rods 602 will move to the left and right sides of the sleeve 2, and the limiting sleeve 603 will disengage from the limiting shaft 7. At this time, the telescopic cylinder 3 and the sleeve 2 lose their limiting position. Push the telescopic cylinder 3 downward and insert it into the sleeve 2 to adjust the height. After adjusting to the appropriate position, release the two support rods 602. The support spring 606 loses its limiting position and drives the support rods 602 to move inward and reset. The limiting sleeve 603 is inserted into the outer surface of the corresponding limiting shaft 7 to limit the position, thus completing the height adjustment of the soil collection device. The adjustment method is convenient and quick, and the height of the soil collection device can be freely set, making it more convenient to use.

[0027] In summary, this utility model uses the locking mechanism 6 to adjust the height of the soil sampling device, making it easier to apply force for soil collection in confined terrain. Moreover, users can adjust the height of the soil sampling device according to their own height, allowing staff of different heights to achieve the best user experience. This solves the problem that the height of the soil sampler needs to be adjusted for better soil collection due to different terrain environments and different sampling personnel.
