Description

Technical Field

[0001] This utility model belongs to the field of soil collection technology, specifically, it relates to a soil sample collection device. Background Technology

[0002] As people pay more and more attention to the environment, the importance of soil environment is also gradually increasing. Soil quality affects the growth of crops or other plants and animals. Therefore, soil testing is an important part of environmental monitoring. Soil testing requires soil sampling. By sampling soil at different depths, soil composition and soil property parameters can be measured and judged, thereby evaluating and studying the degree of soil pollution.

[0003] 1. Existing equipment requires manual drilling when drilling into the soil. During drilling, the inertia of the human body can cause the drill bit to move when entering the soil, resulting in inconsistent soil sample testing and thus inaccurate soil analysis.

[0004] 2. When sampling hardened soil, existing soil drills do not have the function of quickly drilling into the soil, which often requires a lot of time and effort, greatly affecting work efficiency.

[0005] To address the aforementioned issues, this application proposes a soil sample collection device. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a soil sample collection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A soil sample collection device includes a rod; a sampling assembly located below the rod and within a guide assembly; a guide assembly located below the rod and within a support assembly; and a support assembly located below the rod and surrounding the guide assembly. The sampling assembly comprises a sampling rod, a slot, a push rod, a foot plate, a push plate, a drill head, teeth, and slots. The sampling rod is fixedly connected to the bottom of the rod. The outer circumference of the sampling rod has a slot. A push rod is disposed within the inner cavity of the sampling rod. A foot plate is fixedly connected to the top of the push rod and slidably connected within the slot. A push plate is fixedly connected to the bottom of the push rod and slidably connected within the drill head. A drill head is fixedly connected to the bottom of the sampling rod. The bottom of the drill head has teeth, and the outer circumference of the drill head has slots.

[0009] Preferably, the guiding assembly includes a guide ring, a first insert rod, an inner ring, a second insert rod, and a fixing ring. The outer circumferential wall of the sampling rod is rotatably connected to the guide ring, the inner wall of the guide ring is movably connected to the first insert rod, and the other end of the first insert rod is movably connected to the inner ring.

[0010] Preferably, the inner wall of the inner ring is movably connected to a second insertion rod, and the other end of the second insertion rod is movably connected to a fixing ring, wherein the fixing ring is located on the outer circumference of the sampling rod.

[0011] Preferably, the support assembly includes a support ring, a support rod, a fixing block, a fixing drill bit, and a connecting rod. The support ring is provided on the outer circumference of the rod body. The support rod is fixedly connected to the bottom of the support ring. The fixing block is fixedly connected to the outer circumference of the support rod. The fixing drill bit is fixedly connected to the bottom of the support rod.

[0012] Preferably, the outer circumferential wall of the support rod is provided with a connecting rod, and the other end of the connecting rod is fixedly connected to a guide ring on its outer circumferential wall, and the top of the rod is fixedly connected to a handle.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1: When the staff places the equipment, they place the support rod on the soil surface and fix the support rod with the fixed drill bit on the support rod. Then, the inner ring and the fixed ring in the guide ring on the rod body make the sampling rod perpendicular to the ground, thereby achieving the effect of positioning and guiding the drill head.

[0015] 2: When the staff conducts soil sampling, the sampling rod is rotated by turning the handle on the rod. The sampling rod then enters the soil through the drill bit on the sampling rod for sampling. The teeth on the drill bit facilitate the drill bit's faster entry into the soil. After the drill bit has finished collecting the samples, the staff pushes the rod inside the sampling rod by stepping on the foot plate, and then the pusher pushes the soil from the bottom of the drill bit for collection.

[0033] 1: When the staff fixes the equipment, the support rod 402 is placed on the soil surface, and the support rod 402 is fixed on the soil surface by the fixing drill bit 404 on the fixing block 403. Then, the inner ring 303 of the guide ring 301 connected by the connecting rod 405 and the fixing ring 305 make the sampling rod 201 perpendicular to the ground, thereby realizing the positioning and guidance of the drill head.

[0034] 2: When the staff collects soil samples, they rotate the sampling rod 201 by turning the handle 5 on the rod 1. The sampling rod 201 drives the drilling head 206 to drill into the soil surface to collect soil samples. The teeth 207 on the drilling head 206 provide a faster drilling effect into the soil.

[0035] 3: When the staff collects the soil, they step on the foot plate 204 on the sampling rod 201 and push the sampling rod 201 manually to move the push rod 203 inside. The push rod 203 drives the push plate 205 inside the drill head 206 to make the soil flow out from the bottom of the drill head 206, thus facilitating the manual removal of the soil by the staff.
