Description

Technical Field

[0001] This utility model belongs to the technical field of soil sampling, specifically relating to a squeeze sampler for a rapid soil moisture content analyzer. Background Technology

[0002] Before using a soil moisture meter for testing, soil sampling must be completed first. The sampling tube is inserted vertically into the soil layer to fill the tube with soil sample. After sampling, the columnar soil sample inside the tube can be pushed out by pressing the tube, ready for subsequent testing.

[0003] To address situations where soil hardness is high and manual pressing is difficult, an assistive pedal is typically added to the outside of the sampling tube using threaded fasteners. The operator can then use their foot to press the pedal, converting their body weight into downward pressure and thus pressing the sampling tube into the hard soil more effortlessly. However, when deep soil sampling is required, the pedal's relatively fixed position necessitates disassembling and reinstalling it at a higher position after each sampling layer before proceeding to the next layer, making the process time-consuming and laborious. Utility Model Content

[0004] The purpose of this invention is to provide a squeeze sampler for a rapid soil moisture content analyzer, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A squeeze sampler for a rapid soil moisture content analyzer includes a sampling component comprising a T-shaped rod, a first anti-slip sleeve fixedly connected to the outside of the T-shaped rod, a push rod slidably connected inside the T-shaped rod, a push block fixedly connected to the bottom of the push rod, the push block slidably connected to the inner wall of the T-shaped rod, a gripping ball fixedly connected to the top of the push rod, a pressing component and a limiting component provided outside the T-shaped rod; and an auxiliary component including a lifting sleeve slidably connected to the outside of the T-shaped rod, with a positioning component provided inside the lifting sleeve.

[0008] As a preferred embodiment of this utility model, a through hole is provided inside the T-shaped rod at the position corresponding to the lifting rod, and the lifting rod is slidably connected in the through hole.

[0009] In a preferred embodiment of this utility model, the limiting component includes a protective shell, which is fixedly connected to the outside of the T-shaped rod. A slider is slidably connected to the inner wall of the protective shell. An insert plate is fixedly connected to the back of the slider. A handle is fixedly connected to the front of the slider. The handle is slidably connected to the protective shell. A spring is fixedly connected between the front of the slider and the protective shell. A second anti-slip sleeve is fixedly connected to the outside of the handle. A limiting groove is formed inside the lifting rod, and the insert plate is slidably connected inside the limiting groove.

[0010] As a preferred embodiment of this utility model, a through groove is provided inside the T-shaped rod at the position corresponding to the insertion plate, and the insertion plate is slidably connected in the through groove.

[0011] In a preferred embodiment of this utility model, the positioning component includes a screw, which is threadedly connected to the inside of the lifting sleeve. One end of the screw is fixedly connected to a knob, and the end of the screw away from the knob is fixedly connected to an insert block.

[0012] As a preferred embodiment of this utility model, a sliding groove is provided inside the lifting sleeve at the position corresponding to the limiting block, and the limiting block is slidably connected in the sliding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the sampling components, the height of the pedal can be quickly and gradually adjusted in stages with the cooperation of the insertion plate and the limiting groove, ensuring that it is in the optimal assist position for each deep sampling. Combined with the contact indicator between the contact plate and the ground, the penetration depth of the T-shaped rod can be clearly judged, thereby controlling the soil sampling depth and facilitating soil sampling. This avoids the tedious process of repeatedly turning, disassembling and installing the pedal required by the traditional threaded connection method. When conducting deep soil stratification sampling, it can save a lot of time and energy and greatly improve sampling efficiency.

[0015] 2. With the help of the auxiliary components, the lifting sleeve can be limited to a suitable height with the help of the insert block.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a squeeze sampler for a rapid soil moisture content analyzer, including a sampling component, including a T-shaped rod 10. A first anti-slip sleeve 11 is fixedly connected to the outside of the T-shaped rod 10. An ejector rod 12 is slidably connected inside the T-shaped rod 10. An ejector block 13 is fixedly connected to the bottom of the ejector rod 12. The ejector block 13 is slidably connected to the inner wall of the T-shaped rod 10. A gripping ball 14 is fixedly connected to the top of the ejector rod 12. A pressing component 15 and a limiting component 16 are provided on the outside of the T-shaped rod 10.

[0028] Furthermore, the pressing assembly 15 includes a slide tube 151, which is slidably connected to the outside of the T-shaped rod 10. A foot pedal 152 is fixedly connected to the outside of the slide tube 151. An abutment plate 153 is fixedly connected to the bottom of the foot pedal 152. A lifting rod 154 is fixedly connected to the top of the slide tube 151. A grip ring 155 is fixedly connected to the top of the lifting rod 154. By moving the grip ring 155 upward, the height of the lifting rod 154 can be adjusted, making it easier to move the foot pedal 152 to a suitable assist height. After the abutment plate 153 contacts the ground, it is easy to determine the downward height of the T-shaped rod 10, which facilitates soil sampling at different depths.

[0029] The T-shaped rod 10 has a through hole at the position corresponding to the lifting rod 154, and the lifting rod 154 is slidably connected in the through hole to facilitate the lifting and lowering of the lifting rod 154.

[0030] Furthermore, the limiting component 16 includes a protective shell 161, which is fixedly connected to the outside of the T-shaped rod 10. A slider 162 is slidably connected to the inner wall of the protective shell 161. An insert plate 163 is fixedly connected to the back of the slider 162. A handle 164 is fixedly connected to the front of the slider 162. The handle 164 is slidably connected to the protective shell 161. A spring 165 is fixedly connected between the front of the slider 162 and the protective shell 161. A second spring 165 is fixedly connected to the outside of the handle 164. The anti-slip sleeve 166 and the lifting rod 154 have a limiting groove 167 inside. Several limiting grooves 167 are equally spaced. The insert plate 163 is slidably connected inside the limiting groove 167. By pulling the handle 164, the slider 162 compresses the spring 165, thereby moving the insert plate 163 away from the limiting groove 167, thus releasing the limiting work on the lifting rod 154, making it easy to adjust the pedal 152 to the appropriate assist height in multiple steps.

[0031] Preferably, a through groove is provided inside the T-shaped rod 10 at the position corresponding to the insertion plate 163, and the insertion plate 163 is slidably connected in the through groove, which facilitates the movement of the insertion plate 163.

[0032] In use, by holding the first anti-slip sleeve 11 and aligning the T-shaped rod 10 with the ground, the tip of the T-shaped rod 10 is inserted into the ground. By pressing the first anti-slip sleeve 11 and stepping on the pedal 152, the T-shaped rod 10 is inserted into the soil, causing the contact plate 153 to contact the ground, completing the first stage of insertion sampling. When sampling deeper soil is required, by holding the second anti-slip sleeve 166 and pulling the handle 164, the slider 162 is moved, causing the slider 162 to compress the spring 165, thereby moving the insertion plate 163 away from the limiting groove 167, thus releasing the limiting effect on the lifting rod 154. By holding the grip ring 155 and moving it upward a certain distance, the lifting rod 154 and the pedal 152 are moved upward, raising the pedal 152 to a suitable assist height, facilitating subsequent adjustments by the user. Pressing the pedal 152 releases the handle 164, limiting the upward movement of the lifting rod 154. Continue pressing the pedal 152 repeatedly, moving it upwards in segments to ensure it's in the optimal assist position for each deep sampling. When the pedal 152 reaches its maximum allowable height, press it down to lower it, bringing the contact plate 153 into contact with the ground, completing the sampling of deeper soil. Grasp the first anti-slip sleeve 11 and move it upwards to pull the T-shaped rod 10 away from the ground. Align the tip of the T-shaped rod 10 with the material feeding area, and push the holding ball 14 to move the ejector rod 12 downwards, causing the ejector block 13 to move and push the soil out of the cavity of the T-shaped rod 10. Collect the soil for subsequent moisture content testing.

[0033] Example 2

[0034] Reference Figures 6-7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an auxiliary component, which includes a lifting sleeve 20. The lifting sleeve 20 is slidably connected to the outside of the T-shaped rod 10 and the outside of the lifting rod 154. A positioning component 21 is provided inside the lifting sleeve 20.

[0035] Specifically, the positioning component 21 includes a screw 211, which is threaded into the inside of the lifting sleeve 20. One end of the screw 211 is fixedly connected to a knob 212, and the other end of the screw 211 away from the knob 212 is fixedly connected to an insert block 213. The insert block 213 is slidably connected to the lifting sleeve 20 and to the limiting groove 167. The bottom of the insert block 213 is fixedly connected to a limiting block 214, and the top of the lifting sleeve 20 is fixedly connected to a stop block 215, which contacts the T-shaped rod 10. With the cooperation of the insert block 213, the lifting sleeve 20 is easily limited to a suitable height. With the cooperation of the stop block 215, the rising height of the lifting rod 154 is easily positioned, facilitating soil sampling at a specific depth. By physically blocking the movement, the upward sliding stroke of the pedal 152 is precisely limited, thereby controlling the maximum depth of the T-shaped rod 10 penetrating the soil.

[0036] Furthermore, a sliding groove is provided inside the lifting sleeve 20 at the position corresponding to the limiting block 214, and the limiting block 214 is slidably connected in the sliding groove, which facilitates the smooth movement of the insert block 213.

[0037] During use, according to the target depth required for sampling, manually slide the lifting sleeve 20 to the corresponding height position on the outer wall of the T-shaped rod 10, so that the insertion block 213 corresponds to the position of the limiting groove 167 at the appropriate height. By rotating the knob 212, the screw 211 is moved, causing the insertion block 213 to slide into the limiting groove 167, thereby limiting the lifting sleeve 20 and completing the positioning of the abutment block 215. When repeatedly moving the foot pedal 152 upwards for deep sampling, the lifting sleeve 20 is... The lifting sleeve 20 and the stop block 215 are limited to the outside of the lifting rod 154, so the lifting rod 154 will move upward with the lifting rod 154. The lifting rod 154 moves upward until it is blocked by the stop block 215. At this time, it means that the pedal 152 has reached the maximum allowable height. Continuing to press down will allow the T-shaped rod 10 to penetrate to the preset depth. When the stop plate 153 contacts the ground, the tip of the T-shaped rod 10 reaches the preset depth, avoiding the problem of sampling too deep or too shallow due to the operator's lack of experience.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
