Description

Technical Field

[0001] The invention relates to the technical field of land resource detection, and in particular to a soil sampling device for land resource detection. Background Art

[0002] Land, as the basis for human survival, is of vital importance for its rational use and protection. Land resources refer to land that can be used by humans under specific technical conditions and time frames. Soil, as the core component of land resources, is a loose layer on the earth's surface that is fertile and can grow plants, formed under the long-term combined effects of multiple factors such as biology, climate, parent material, topography, and time.

[0003] Different soil qualities reflect the different nature and methods of land resource utilization. Accurate soil quality testing is crucial in land resource research fields such as land use change, soil quality and health. However, the quality of soil sampling methods and techniques directly affects the results of soil quality inspection. Especially in mountainous and hilly areas, the high gravel content in the soil increases the difficulty of subsequent processing of soil samples.

[0004] Traditional soil sampling methods have many disadvantages. For example, common soil drilling sampling, although less damage to the soil and can be layered, is less efficient when faced with complex terrain and special soil conditions. Using a shovel to dig a profile pit to collect samples is not only labor-intensive, but also easily causes significant damage to the soil structure.

[0005] In order to improve the efficiency of soil sampling and reduce the interference of soil testing results, it is necessary to improve and invent soil sampling devices for land resource testing. It can effectively solve the shortcomings of traditional sampling methods and collect soil samples more efficiently under different soil environments and terrain conditions, providing more reliable technical support for the rational use and protection of land resources. Summary of the invention

[0006] The purpose of the present invention is to solve the problem in the prior art that when soil sampling is carried out in mountainous areas or rocky areas, various rocks will be mixed in the soil samples, which will affect the results of subsequent soil testing, reduce the accuracy of the soil testing results of the device, and have low efficiency. A soil sampling device for land resource testing is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The soil sampling device for land resource detection includes a base, a connection box is arranged above the base, and a screening mechanism is installed outside the connection box. The core component of the screening mechanism is a driving motor, and its output end is connected to a driving rod. The side of the driving rod away from the motor is fixed with an axis plate, and the other end of the axis plate is rotatably connected to a pull rod. The other side of the pull rod is rotatably connected to the connecting rod, and a baffle is fixed on the side of the connecting rod.

[0009] The baffle is equipped with a filter plate inside and a fixed plate on the side. An elastic vibrator is provided under the fixed plate, which is fixed to the connection box. When the drive motor is started, the drive rod drives the shaft plate to rotate, and the shaft plate makes the connecting rod reciprocate through the pull rod. The connecting rod then drives the baffle and the filter plate to reciprocate. Under the action of the fixed plate and the elastic vibrator, the filter plate vibrates during movement, thereby separating the rock and the soil.

[0010] The above technical solution further includes:

[0011] The connection box is fixedly connected to the driving motor, and the elastic vibrator has an elastic function. A support plate is fixedly connected above the base, a mounting plate is fixedly connected to the side of the support plate away from the base, and the support plate is fixedly connected to the connection box.

[0012] A soil extraction mechanism is arranged above the mounting plate, and the mechanism includes a base plate mounted outside the mounting plate. A driving assembly is fixedly mounted on the side of the base plate, and the output end of the driving assembly is connected to the hollow cylinder. A telescopic extraction pipe is arranged on one side of the hollow cylinder away from the driving assembly, and a discharge pipe is fixedly connected to the other side. The discharge pipe is fixedly connected to the base plate.

[0013] A feeding cavity is set below the connection box, and the edges of the feeding cavity are in a bevel shape. An electric telescopic box is set above the side of the base close to the feeding cavity, and a soil quality detector is fixedly installed on the side close to the electric telescopic box. The soil quality detector can move under the action of the electric telescopic box, and a display screen is embedded above it. The sensor inside the soil quality detector is the core component, which can convert parameters such as temperature, humidity, pH value, nutrient content, etc. in the soil into electrical signals for measurement.

[0014] The side of the baffle is fixedly connected to the slide, and a storage box fixedly connected to the base is provided under the slide. Multiple sets of universal wheels are provided at the bottom of the base, which enables the device to be mobile and facilitates soil sampling and testing operations at different locations, effectively improving the flexibility and scope of application of the device.

[0015] The present invention has the following beneficial effects:

[0016] 1. In terms of the screening mechanism, through ingenious construction, the drive motor is used to drive the shaft plate, pull rod, connecting rod and baffle to move back and forth, and combined with the limiting effect of the fixed plate and the elastic vibrator, the filter plate vibrates during the movement. This design can quickly separate the rock and soil in the soil sample, and is especially suitable for soil sampling in mountainous areas or areas with many rocks. It effectively avoids the problem of soil samples mixing with rocks and affecting the subsequent soil quality test results, significantly improves the purity of soil sampling, provides a guarantee for the accuracy of subsequent tests, and also improves the working efficiency of the device.

[0017] 2. The soil extraction mechanism is also unique. It controls the telescopic extraction tube through the drive component to extract soil samples from the land, and uses the hollow cylinder and the discharge tube to transfer the soil samples to the screening mechanism for separation. This automated process reduces manual operations, not only improves sampling efficiency, but also ensures the representativeness of soil samples. The screened soil samples are transferred to the electric telescopic box through the discharge cavity. The soil quality detector controls the movement of the electric telescopic box to send the soil samples into the detector for testing. The test information is displayed in real time on the display screen, which is convenient for staff to observe and record, further improving the test efficiency and accuracy.
