Technical Field
[0001] This utility model relates to the field of soil testing equipment technology, and in particular to a soil ecological environment sampling device. Background Technology
[0002] Soil ecological environment refers to the sum of biological and abiotic environments in soil, including soil physical structure, chemical composition, microbial community and other aspects. Soil ecological environment has a vital impact on plant growth, ecological balance and human production and life. In order to gain a deeper understanding of the state of soil ecological environment, researchers need to sample and analyze the soil. Soil ecological environment sampling device is a special equipment used to collect soil samples.
[0003] The existing soil ecological environment sampling device has the following shortcomings:
[0004] Some existing sampling devices lack a reliable soil sample fixation and separation structure when the hollow drill is inserted into the soil for sampling. This makes it difficult to remove the soil sample along with the hollow drill when it is pulled out, or the sample may slip inside the hollow drill and fail to be collected completely. At the same time, after sampling is completed, the existing devices lack a convenient and efficient sample ejection structure, making it difficult for operators to smoothly remove the collected soil sample from the sampling device, which brings many inconveniences to subsequent soil testing work. Utility Model Content
[0005] This invention proposes a soil ecological environment sampling device. A hollow drill is inserted into the soil, and the sample enters the interior. The rotating connecting cylinder drives the rotating support plate to squeeze the soil, separate the sample, and provide support, ensuring that the sample is taken out simultaneously when the hollow drill is pulled out. After sampling is completed, the sample can be easily pushed out by pushing the ejection handle, which facilitates subsequent testing and solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a soil ecological environment sampling device, including a connecting sleeve, a sampling component fixedly connected to the front end of the connecting sleeve, an ejector component slidably inserted into the rear end of the inner surface of the connecting sleeve, and a pressing handle fixedly connected to the left and right sides of the rear of the outer surface of the connecting sleeve.
[0007] The sampling assembly includes a hollow drill, with a connecting cylinder rotatably connected to the rear side of the inner surface of the hollow drill, and four rotating brackets movably connected to the front end of the connecting cylinder in a ring array.
[0008] The rotating bracket includes a rotating support plate. The inner surface of the hollow drill has four movable grooves arranged in a ring array on the front side. The rotating support plate is rotatably connected inside the movable grooves. A sliding post is slidably inserted into the rear end of the rotating support plate. A rotating block one is rotatably connected to the rear end of the sliding post. A rotating column is rotatably connected to the outer surface of the rotating block one. A rotating block two is rotatably connected to the end of the rotating column away from the rotating block one. The front end of the connecting cylinder has four connecting grooves arranged in a ring array. The rear end of the rotating block two is rotatably connected to the inner wall of the connecting groove.
[0009] Preferably, a spiral spring is fixedly connected to the rear side of the connecting cylinder, and the end of the spiral spring away from the connecting cylinder is fixedly connected to the inner wall of the hollow drill.
[0010] Preferably, the ejection assembly includes an ejection rod, the outer surface of which is slidably connected to the inner surface of the connecting sleeve, and an ejection handle is fixedly connected to the rear end of the ejection rod.
[0011] Preferably, a sliding pressure plate is fixedly connected to the rear side of the outer surface of the ejector rod, a connecting groove is provided on the rear side of the inner surface of the connecting sleeve, the sliding pressure plate is slidably connected inside the connecting groove, and a return spring is fixedly connected to the front end of the sliding pressure plate, the return spring being disposed on the outer surface of the ejector rod.
[0012] Preferably, the front end of the ejector rod extends through the interior of the connecting cylinder and is fixedly connected to an ejector plate, the outer surface of the ejector plate being slidably connected to the inner surface of the connecting cylinder.
[0013] Preferably, a limiting groove is provided on the rear side of the inner surface of the connecting cylinder, and a limiting plate is fixedly connected to the rear side of the ejector plate, with the outer surface of the limiting plate slidably inserted into the inner surface of the limiting groove.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. In this utility model, when the hollow drill is inserted into the soil, the sample enters the interior of the hollow drill. When the connecting cylinder rotates, the second rotating block rotates accordingly. Through the transmission of the rotating column, the first rotating block, and the sliding insert, the rotating support plate rotates on the inner wall of the hollow drill. The rotating support plate squeezes the soil, realizing the separation of the soil from the sample, and at the same time providing support for the soil sample in the connecting cylinder. In this way, when the hollow drill is pulled out, the soil sample in the connecting cylinder can be taken out synchronously, effectively avoiding the problem that the soil sample cannot be taken out with the hollow drill or slips into the hollow drill, thus ensuring the integrity of the soil sample collection.
[0016] 2. In this utility model, after soil sampling is completed, the push handle is pushed, and the push rod drives the push plate to slide inside the connecting cylinder, ensuring that the push plate moves smoothly, thereby pushing the sampled soil out of the hollow drill. The whole process is simple to operate, greatly improving the convenience of pushing out the soil after sampling, and facilitating the subsequent soil testing work. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: including a connecting sleeve 1, a sampling component 2 fixedly connected to the front end of the connecting sleeve 1, an ejection component 3 slidably inserted into the rear end of the inner surface of the connecting sleeve 1, and pressing handles 11 fixedly connected to the left and right sides of the rear of the outer surface of the connecting sleeve 1. The ejection component 3 includes an ejection rod 31, the outer surface of the ejection rod 31 is slidably connected to the inner surface of the connecting sleeve 1, an ejection handle 32 is fixedly connected to the rear end of the ejection rod 31, a sliding pressure plate 33 is fixedly connected to the rear side of the outer surface of the ejection rod 31, a connecting groove 12 is opened on the rear side of the inner surface of the connecting sleeve 1, the sliding pressure plate 33 is slidably connected inside the connecting groove 12, a return spring 34 is fixedly connected to the front end of the sliding pressure plate 33, the return spring 34 is disposed on the outer surface of the ejection rod 31, the front end of the ejection rod 31 penetrates into the interior of the connecting cylinder 22 and is fixedly connected to an ejection plate 311, and the outer surface of the ejection plate 311 is slidably connected to the inner surface of the connecting cylinder 22.
[0025] The overall effect of Embodiment 1 is as follows: the downward handle 11 provides the operator with a force point, making it easy to press the sampling component 2 into the soil. After the soil sampling is completed, the operator pulls the push-out handle 32 backward, and the push-out rod 31 moves backward accordingly, driving the push-out plate 311 to move backward synchronously in the connecting cylinder 22. During this process, the sliding pressure plate 33 slides in the connecting groove 12, restricting the movement trajectory of the push-out rod 31 and ensuring its smooth movement. At the same time, the return spring 34 is compressed and stores elastic potential energy. When the soil sample is pushed out, the push-out handle 32 is released, the return spring 34 releases elastic potential energy, and pushes the sliding pressure plate 33 and the push-out rod 31 forward to reset, preparing for the next sampling operation, which greatly improves the convenience of pushing out the soil sample.
[0026] Example 2: As Figure 3 and Figure 4As shown, this utility model provides a technical solution: a limiting groove 221 is formed on the rear side of the inner surface of the connecting cylinder 22; a limiting plate 312 is fixedly connected to the rear side of the ejector plate 311; the outer surface of the limiting plate 312 is slidably inserted into the inner surface of the limiting groove 221; the sampling assembly 2 includes a hollow drill 21; the connecting cylinder 22 is rotatably connected to the rear side of the inner surface of the hollow drill 21; four rotating brackets 23 are movably connected to the front end of the connecting cylinder 22 in a circular array; each rotating bracket 23 includes a rotating support plate 231; four movable grooves are formed in a circular array on the front side of the inner surface of the hollow drill 21; and the rotating support plate 231 is rotatably connected to the movable grooves. Inside the groove, a sliding insert post 232 is slidably inserted into the rear end of the rotating support plate 231. A rotating block 233 is rotatably connected to the rear end of the sliding insert post 232. A rotating column 234 is rotatably connected to the outer surface of the rotating block 233. A rotating block 235 is rotatably connected to the end of the rotating column 234 away from the rotating block 233. Four connecting grooves 222 are arranged in a ring array at the front end of the connecting cylinder 22. The rear end of the rotating block 235 is rotatably connected to the inner wall of the connecting groove 222. A spiral spring 24 is fixedly connected to the rear side of the connecting cylinder 22. The end of the spiral spring 24 away from the connecting cylinder 22 is fixedly connected to the inner wall of the hollow drill 21.
[0027] The overall effect achieved in Embodiment 2 is as follows: When the hollow drill 21 is inserted into the soil, the soil sample enters the interior of the hollow drill 21. At this time, rotating the ejector rod 31 causes the ejector plate 311 to rotate through the engagement between the limiting plate 312 and the limiting groove 221, thereby squeezing the spiral spring 24 to accumulate elastic force. When the connecting cylinder 22 rotates, the rotating block 235 rotates within the connecting groove 222. Through the rotating column 234, the rotating block 233, and the sliding insert 232, the effect is achieved. The transmission causes the rotating tray 231 to rotate on the inner wall of the hollow drill 21. The rotating tray 231 squeezes the soil, realizing the separation of soil and sample, and at the same time provides support for the soil sample in the connecting cylinder 22, ensuring the integrity of soil sample collection. When it is necessary to remove the sample, the rotation of the ejector rod 31 is released, and the connecting cylinder 22 can be reset by the elastic force of the spiral spring 24, and the rotating tray 231 is reset into the movable groove, which facilitates the ejection of the soil sample from the hollow drill 21.
[0028] The working principle of the entire device is as follows: the operator holds the down handle 11 with both hands, checks whether the connection of each component of the device is secure, ensures that the ejector rod 31 is in the initial position, the sliding pressure plate 33 is located at the front end of the connecting slide 12, the return spring 34 is not compressed, and the rotating support plate 231 of the rotating bracket 23 is in the movable groove of the hollow drill 21.
[0029] By applying force by pressing down the handle 11, the hollow drill 21 is vertically pressed into the soil. As the hollow drill 21 continues to penetrate deeper, soil samples gradually enter the interior of the hollow drill 21. When the hollow drill 21 enters the soil, the ejector rod 31 is rotated. The ejector plate 311, through the engagement of the limiting plate 312 and the limiting groove 221, drives the connecting cylinder 22 to rotate, compressing the spiral spring 24 to accumulate elastic force. During the rotation of the connecting cylinder 22, the rotating block 235 rotates within the connecting groove 222, and through the rotating column 234, The transmission of the rotating block 233 and the sliding insert 232 causes the rotating tray 231 to rotate on the inner wall of the hollow drill 21. The rotating tray 231 squeezes the soil to separate the soil from the sample, and at the same time provides support for the soil sample in the connecting cylinder 22 to prevent the sample from sliding or falling in the hollow drill 21. After the required sampling depth is achieved, the operator pulls the entire sampling device vertically out of the soil. Due to the support of the rotating tray 231 for the sample, the soil sample in the connecting cylinder 22 will be taken out along with the device.
[0030] Afterwards, the operator pushes the ejector handle 32, and the ejector rod 31 moves accordingly, causing the ejector plate 311 to move within the connecting cylinder 22. During this process, the sliding pressure plate 33 slides within the connecting groove 12, restricting the movement trajectory of the ejector rod 31 and ensuring its smooth movement. At the same time, the return spring 34 is compressed, storing elastic potential energy. When the soil sample is ejected from the hollow drill 21, the ejector handle 32 is released, and the return spring 34 releases its elastic potential energy, pushing the sliding pressure plate 33 and the ejector rod 31 forward to reset, preparing for the next sampling operation. At the same time, before ejecting the sample, the rotation of the ejector rod 31 is released, and the spiral spring 24 releases its stored elastic force, causing the connecting cylinder 22 to rotate in the opposite direction to reset, so that the rotating support plate 231 is reset into the movable groove, reducing the obstruction to the ejection of the sample. Then, following the above operation method, the ejector handle 32 is pushed to eject the soil sample from the hollow drill 21.
[0031] After the sample is ejected, ensure that all components of the device are restored to their initial state to prepare for the next soil sampling.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
