Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an automatic soil sampler for environmental monitoring. Background Technology
[0002] Environmental monitoring is a process of testing and evaluating environmental samples to monitor environmental pollution and the health of ecosystems. It involves monitoring and analyzing environmental factors such as air, water, soil, and organisms to assess environmental quality, pollutant emissions, and the health of ecosystems. Environmental monitoring is an important component of environmental protection efforts, providing a scientific basis for environmental governance and decision-making.
[0003] Currently, soil environmental testing often requires operators to collect several sets of soil samples at equal intervals in the area to be tested. Then, the components of these soil samples are analyzed. By calculating, comparing, and analyzing the data of each component in the soil samples, the specific condition of the soil can be determined. However, the current soil sampling operation requires direct operator participation, using tools such as shovels, measuring rulers, or positioning flags. In order to ensure the accuracy of the data, multiple areas need to be selected for testing in the area to be tested. The entire soil sampling process is labor-intensive and difficult, reducing the convenience and efficiency of the actual soil sampling operation.
[0004] In view of this, it is particularly important to design and manufacture an automatic soil sampler that can automatically sample the testing area and improve the convenience and efficiency of soil sampling, and apply it in the process of soil environmental testing. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that the original soil sampling operation required operators to directly use tools, resulting in poor convenience and low efficiency in actual soil sampling operations, and to propose an automatic soil sampler for environmental testing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic soil sampler for environmental monitoring includes a vehicle body and a sampling box disposed on top of the vehicle body. A third motor is installed at the lower end of the vehicle body below the sampling box. The sampling box is detachably mounted on the drive shaft of the third motor. The sampling box has multiple collection troughs arranged in a circular array. A soil sampling mechanism for automatically transporting soil into the collection troughs is disposed at the upper end of the vehicle body on the left side of the sampling box.
[0008] As a further description of the above technical solution:
[0009] The soil sampling mechanism includes a sampling cylinder movably mounted on the vehicle body, a discharge pipe connected to the upper right side of the sampling cylinder and facing the collection trough, a top frame fixed to the upper end of the sampling cylinder, a second motor mounted on the upper end of the top frame, a spiral blade mounted on the lower end of the second motor and located inside the sampling cylinder, and an electric hydraulic cylinder mounted between the vehicle body and the top frame.
[0010] As a further description of the above technical solution:
[0011] The upper end of the vehicle body is symmetrically and fixedly connected to two limiting sleeves below the top frame, and the lower end of the top frame is symmetrically and fixedly connected to two limiting posts that match the limiting sleeves.
[0012] As a further description of the above technical solution:
[0013] The upper part of the vehicle body is detachably fitted with a cover plate above the sampling box, and the left end of the cover plate is provided with a discharge port between the discharge pipe and the collection trough.
[0014] As a further description of the above technical solution:
[0015] Two sets of wheels are symmetrically mounted on both sides of the lower end of the vehicle body. A first motor is installed between the vehicle body and one set of wheels, and the two sets of wheels are connected by a transmission chain.
[0016] As a further description of the above technical solution:
[0017] A lithium battery is installed on the lower right side of the vehicle body, and a digital display controller is installed on the upper left side of the vehicle body.
[0018] As a further description of the above technical solution:
[0019] The output terminal of the lithium battery is electrically connected to the input terminal of the digital display controller, and the output terminal of the digital display controller is electrically connected to the input terminals of the first motor, the second motor, the electric cylinder, and the third motor, respectively.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0021] This invention provides a sampler structure for automatic soil sampling. The automatic sampler mainly consists of four parts: a vehicle body, a sampling box, a soil sampling mechanism, and a digital display controller. The vehicle body can travel in a straight line within the detection area. When the soil sampling mechanism is working, the sampling cylinder can descend into the ground under the extension and retraction of the electric hydraulic cylinder. At the same time, the second motor drives the spiral blades to rotate, conveying the soil that has entered the sampling cylinder upwards. Then, the soil is conveyed through the discharge pipe to the sampling slot at a designated position on the sampling box. This structure enables fixed-distance sampling of soil in the detection area, effectively reducing the workload and difficulty of actual sampling operations for operators, thereby improving the convenience and efficiency of soil sampling operations.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-3This utility model provides a technical solution: an automatic soil sampler for environmental testing, including a vehicle body 1 and a sampling box 701 disposed on the upper part of the vehicle body 1. A third motor 7 is installed at the lower end of the vehicle body 1 below the sampling box 701. The sampling box 701 is detachably mounted on the drive shaft of the third motor 7. The sampling box 701 has multiple collection troughs 702 arranged in a circular array. A soil sampling mechanism for automatically transporting soil into the collection troughs 702 is provided at the upper end of the vehicle body 1 on the left side of the sampling box 701.
[0029] Specifically, such as Figure 1-3 As shown, the soil sampling mechanism includes a sampling cylinder 3 movably mounted on the vehicle body 1, a discharge pipe 301 connected to the upper right side of the sampling cylinder 3 and facing the collection trough 702, a top frame 4 fixed to the upper end of the sampling cylinder 3, a second motor 5 mounted on the upper end of the top frame 4, a spiral blade 501 mounted on the lower end of the second motor 5 and located inside the sampling cylinder 3, and an electric hydraulic cylinder 6 mounted between the vehicle body 1 and the top frame 4. When the electric hydraulic cylinder 6 extends and retracts, it can drive the sampling cylinder 3 to move upward or downward as a whole, thereby realizing the downward sampling and upward reset of the soil.
[0030] Among them, two limiting sleeves 103 are symmetrically fixedly connected to the upper end of the car body 1 below the top frame 4, and two limiting posts 401 that match the limiting sleeves 103 are symmetrically fixedly connected to the lower end of the top frame 4. The setting of the limiting sleeves 103 and the limiting posts 401 improves the stability of the overall lifting and lowering movement of the top frame 4 on the car body 1.
[0031] In addition, a cover plate 8 is detachably installed on the upper part of the vehicle body 1 above the sampling box 701. The left end of the cover plate 8 is provided with a discharge port 801 between the discharge pipe 301 and the collection trough 702. This structure of the cover plate 8 can prevent soil from falling into the collection trough 702 after sampling and before sampling, and can allow the soil discharged through the discharge pipe 301 to fall into the open collection trough 702 through the discharge port 801.
[0032] Specifically, such as Figure 1-3 As shown, two sets of traveling wheels 101 are symmetrically and rotatably mounted on both sides of the lower end of the vehicle body 1. A first motor 2 is installed between the vehicle body 1 and one set of traveling wheels 101. The two sets of traveling wheels 101 are connected by a transmission chain 102. The transmission chain 102 allows the two sets of traveling wheels 101 to rotate synchronously, so that when the first motor 2 is working, the two sets of traveling wheels 101 can perform stable walking operations in the sampling area.
[0033] Specifically, such as Figure 1-3As shown, a lithium battery 9 is installed on the lower right side of the vehicle body 1, which can provide mobile on-board power supply for the first motor 2, the second motor 5, the electric cylinder 6, the third motor 7, and the digital display controller 10, ensuring that the automatic sampler can operate normally. A digital display controller 10 is installed on the upper left side of the vehicle body 1. The output end of the lithium battery 9 is electrically connected to the input end of the digital display controller 10. The output end of the digital display controller 10 is electrically connected to the input ends of the first motor 2, the second motor 5, the electric cylinder 6, and the third motor 7, respectively. The settings of the digital display controller 10 can enable the operator to set the working parameters of the first motor 2, the second motor 5, the electric cylinder 6, and the third motor 7, as well as to program and automate the operation of the first motor 2, the second motor 5, the electric cylinder 6, and the third motor 7.
[0034] Working Principle: During operation, the operator pushes the vehicle body 1 or controls it via the digital display controller 10 to move it to the testing area. The operator can then set the specific operating parameters of the first motor 2, second motor 5, electric cylinder 6, and third motor 7 through the digital display controller 10, thereby setting parameters such as travel interval distance, sampling and feeding rate, sampling depth, and adjustment of the collection trough 702 position. In actual operation, the first motor 2 drives the traveling wheels 101 to rotate, propelling the vehicle body 1 a certain distance across the testing area. Once the set distance is reached, the digital display controller 10 controls the second motor 5 and electric cylinder 6 to work synchronously. The second motor 5 drives the spiral blades 501 to rotate at a constant speed, while the electric cylinder 6 extends inwards. At this point, the sampling cylinder 3 moves vertically downwards towards the soil, and the collected soil sample is collected by the spiral blades 501. Under the rotation of motor 1, the material enters downward through the discharge pipe 301 on the sampling cylinder 3 into the collection trough 702 at the designated position on the sampling box 701. After a single sampling is completed, the digital display controller 10 can pre-control the electric cylinder 6 to reset upward to the initial working position and the second motor 5 to stop rotating. At this time, the entire sampling cylinder 3 can be reset upward onto the vehicle body 1. Then, the digital display controller 10 can continue to control the first motor 2 and the third motor 7 to work. The first motor 2 can drive the walking wheel 101 to rotate, thereby driving the vehicle body 1 to the next sampling position at a fixed distance. When the third motor 7 is working, it can drive the sampling box 701 to rotate at a designated angle. The unfilled collection trough 702 can rotate to below the discharge pipe 301 and the drop port 801, and the collection trough 702 containing soil samples can rotate to below the cover plate 8, so that the automatic sampling operation of the next sampling area can be carried out.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
