Description

Technical Field

[0001] The utility model relates to the technical field of soil quality evaluation, in particular to a soil quality evaluation system. Background Art

[0002] At present, the collection and processing of soil samples is an important prerequisite for the correctness of soil testing and evaluation data. Collecting representative samples is a prerequisite for accurately reflecting the nutritional status of the soil. The detection error caused by the collection of soil samples is greater than any analytical error, and this error can reach 85% of the total process error from the physical and chemical analysis process. In order to reduce the sampling error, the number of samples must be increased, and too many samples will cause difficulties in analysis.

[0003] In traditional engineering projects, soil sampling often requires manual excavation and sampling of the soil surface, which is extremely inconvenient for collecting soil samples extending underground. Therefore, a soil quality evaluation system is urgently needed to solve the problems of low automation and poor sampling accuracy in the traditional sampling process. Utility Model Content

[0004] In view of this, the utility model proposes a soil quality evaluation system, aiming to solve the problems of low automation and poor sampling accuracy in the traditional sampling process.

[0009] A propulsion assembly, the propulsion assembly being used to extend into the bottom surface;

[0010] The rotating component is arranged inside the propulsion component and is used for rotation sampling.

[0011] In some embodiments of the present application, the soil quality evaluation system further includes:

[0012] A fixing rod has one end connected to the lower surface of the fixing seat, and the other end of the fixing rod extends into the bottom surface for fixing.

[0013] In some embodiments of the present application, the propulsion assembly includes:

[0014] A slide rail, which is arranged on the inner sides of the two supporting rods;

[0015] The sliding block is arranged on the two sliding rails, and the sliding block moves relative to the sliding rails.

[0016] In some embodiments of the present application, the propulsion assembly further comprises:

[0017] A propulsion cylinder is arranged on the upper surfaces of the two slide rails, and the upper surface of the sliding block is connected to the driving rod of the propulsion cylinder.

[0018] In some embodiments of the present application, the propulsion assembly further comprises:

[0019] A support plate is arranged on the inner side of the two sliding blocks and connected with the two sliding blocks.

[0020] In some embodiments of the present application, the propulsion assembly further comprises:

[0021] Limit blocks are arranged at both ends of the slide rail, and the limit blocks are used to limit the moving range of the slide block.

[0022] In some embodiments of the present application, the rotating assembly includes:

[0023] A stepper motor is arranged on the support plate;

[0024] The sampling rod has one end connected to the driving end of the stepping motor and the other end in a cone shape, with a spoon-shaped opening provided on one side close to the cone end.

[0025] Compared with the prior art, the beneficial effect of the utility model is that, in the utility model, a fixed seat is provided, a fixed rod is provided on the fixed seat and extends below the ground, the stability and normal operation of the soil quality evaluation system in the utility model are guaranteed by the fixed seat and the fixed rod, a propulsion component and a sampling component are provided, and the sampling component is driven to move up and down by a propulsion cylinder, and at the same time, a slide rail, a sliding block and a support plate are provided on the support rod to ensure the stability of the up and down movement of the sampling component, and a limit block is provided to accurately control the up and down movement distance of the sampling component, thereby ensuring the consistency of multi-point sampling, and a sampling motor is provided on the support plate to move the sampling component up and down. One end of the rod is connected to the driving end of the stepper motor. When the propulsion assembly drives the sampling assembly to move downward and enter the preset sampling position below the ground, the sampling rod is controlled to rotate by the stepper motor. By setting a spoon-shaped opening on one side of the tapered end of the sampling rod, when the sampling rod is in a rotating state, it drives the collection of soil samples through the spoon-shaped opening. At the same time, the rotation of the spoon-shaped opening is conducive to the collection of soil samples, avoiding the problem of false soil sample collection due to relying solely on the up and down movement of the sampling rod, and avoiding the problem of large deviation in soil sample quality collection. The comprehensive setting in the utility model improves the degree of automation of the equipment and reduces the error of manual labor. BRIEF DESCRIPTION OF THE DRAWINGS
