[0002] With the current social and economic development, soil problems are becoming more and more prominent. Driven by the Soil Pollution Prevention and Control Law, soil environmental surveys are being carried out in full swing in various places, especially soil environmental monitoring surveys of industrial production sites. Due to the heterogeneity of soil, the collection of soil samples has become the most critical step in soil monitoring. Accurately collecting soil samples that meet regulatory requirements can provide quality assurance for various subsequent test data.
[0003] The existing technology has the following problems:
[0004] When sampling soil layers, most sampling devices will use the elasticity of the spring to insert the stratification shovel halfway and bring the soil back. However, when the spring is stretched, part of it will enter the soil, and the relative resilience will become worse, which is not conducive to subsequent cleaning. Utility Model Content

[0015] The utility model provides a layered sampling device for soil survey sampling. By using a storage mechanism, excess soil can be isolated outside, so as to protect the sampling equipment and avoid damage or blockage of the equipment due to particles or impurities in the soil. When in use, a motor will start the threaded rod to rotate, and at the same time, a drill pipe at the lower end of the threaded rod will also rotate together and drive the drill bit to drill the ground.

Relatively, when the moving block rises, the collecting boxes on both sides thereof descend at the same time. The slide block slides on the slide rail. Because the moving block has a conical slope, when the collecting box slides downward in the sliding groove, it will also be farther and farther away from the screw rod, so that the collecting box can be extended from the through hole on the drill pipe. When the collecting box is extended, the soil blocked in the through hole will be pushed out, and a cross-section rod is provided on the side of the collecting box close to the soil. The cross-section rod can intercept part of the soil entering the collecting box, thereby realizing effective sampling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1-5 As shown, a stratified sampling device for soil survey sampling includes a protective tube 1, a mounting plate 2 is provided at the upper end of the protective tube 1, a motor 3 is provided at the upper end of the mounting plate 2, a threaded rod 7 is connected to the lower end of the motor 3, a storage mechanism 8 is fixedly connected to the lower end of the threaded rod 7, a sampling mechanism 9 is provided inside the storage mechanism 8, a drill bit 6 is fixedly connected to the lower end of the sampling mechanism 9, a bottom plate 5 is fixedly connected to the lower end of the protective tube 1, and support rods 4 are symmetrically provided on both sides of the protective tube 1.
[0025] The storage mechanism 8 includes a drill pipe 81 , a fixed base 83 is provided at the lower end of the drill pipe 81 , a plurality of through holes 82 are symmetrically opened on the drill pipe 81 , and the top of the drill pipe 81 is fixedly connected to the threaded rod 7 .
[0026] By using the storage mechanism 8, excess soil can be isolated outside, which can protect the sampling equipment and avoid damage or blockage of the equipment due to particles or impurities in the soil. When in use, the motor will start the threaded rod 7 to rotate, and the drill pipe 81 at the lower end of the threaded rod 7 will also rotate and drive the drill bit 6 to drill the ground. Because the drill bit 6 will squeeze the soil outward during drilling, the drill pipe 81 can be completely submerged in the soil. When the sampling is completed, the motor 3 drives the threaded rod 7 to reverse and make the drill pipe 81 rise. When the drill pipe 81 rises, it will enter the protective tube 1. The inner ring at the bottom of the protective tube 1 can scrape off the excess soil on the drill pipe 81, and can quickly and efficiently clean the soil adhered to the surface of the mechanism, thereby saving sampling time and improving work efficiency.
[0027] like Figure 1-5As shown, a stratified sampling device for soil survey sampling, the sampling mechanism 9 includes a moving block 91, the lower end of the moving block 91 is fixedly connected to the expansion platform 97, the upper end of the moving block 91 is provided with a servo motor 92, the lower end of the servo motor 92 is installed with a screw rod 93, and the screw rod 93 passes through the moving block 91 and the expansion platform 97.
[0028] The sampling mechanism 9 also includes sliding grooves 96 symmetrically opened on both sides of the moving block 91, and sliding rails 99 are symmetrically arranged on both sides of the sliding grooves 96. A slider 98 is slidably installed on one side of the sliding rails 99 close to each other. A collecting box 94 is fixedly connected to the side of the slider 98 away from the moving block 91. A cross-section rod 95 is arranged on the collecting box 94 away from the slider 98, and the moving block 91 has a conical slope.
[0029] The interior of the mounting plate 2 is threadedly connected to the threaded rod 7 .
[0030] The sampling mechanism 9 can be used to perform layered sampling when sampling the soil, saving manpower while improving the sampling efficiency. When the drill bit 6 stops rotating, the servo motor 92 is started to drive the screw rod 93 to rotate. When the screw rod 93 rotates, the moving block 91 moves upward. Relatively speaking, when the moving block 91 rises, the collecting boxes 94 on both sides thereof simultaneously descend, and the slider 98 slides on the slide rail 99. Because the moving block 91 has a conical slope, when the collecting box 94 slides downward in the sliding groove 96, it will also be farther and farther away from the screw rod 93, so that the collecting box 94 can extend from the through hole 82 on the drill pipe 81. When the collecting box 94 is extended, the soil blocked in the through hole 82 will be pushed out, and a cross-section rod 95 is provided on the side of the collecting box 94 close to the soil. The cross-section rod 95 can intercept part of the soil entering the collecting box 94, thereby achieving effective sampling.
[0031] The working principle of the utility model is as follows: by using the storage mechanism 8, the excess soil can be isolated outside, the sampling equipment can be protected, and the equipment can be prevented from being damaged or blocked by particles or impurities in the soil. When in use, the motor will start the threaded rod 7 to rotate, and at the same time, the drill pipe 81 at the lower end of the threaded rod 7 will also rotate together and drive the drill bit 6 to drill the ground. Because the drill bit 6 will squeeze the soil outward during drilling, the drill pipe 81 can be completely submerged in the soil. Through the sampling mechanism 9, stratified sampling can be performed when sampling the soil, saving manpower while improving the sampling efficiency. When the drill bit 6 stops rotating, the servo motor 92 is started, so that the servo motor 92 drives the screw rod 93 to rotate. When the screw rod 93 rotates, the moving block 91 moves upward. Conversely, when the moving block 91 rises, the collecting boxes 94 on both sides thereof simultaneously descend, and the slide Block 98 slides on the slide rail 99. Since the moving block 91 has a conical slope, when the collecting box 94 slides downward in the sliding groove 96, it will be farther and farther away from the screw rod 93, so that the collecting box 94 can extend from the through hole 82 on the drill pipe 81. During the extension of the collecting box 94, the soil blocked in the through hole 82 will be pushed out, and a cross-section rod 95 is provided on the side of the collecting box 94 close to the soil. The cross-section rod 95 can intercept part of the soil entering the collecting box 94, thereby achieving effective sampling. When the sampling is completed, the motor 3 drives the threaded rod 7 to reverse, so that the drill pipe 81 rises. When the drill pipe 81 rises, it will enter the protective tube 1. The inner ring at the bottom of the protective tube 1 can scrape off the excess soil on the drill pipe 81, and can quickly and efficiently clean the soil adhering to the surface of the mechanism, thereby saving sampling time and improving work efficiency.
