[0002] The forestry soil sampling device is a tool used to collect forest soil samples. It can be inserted into the soil and take out soil samples at a certain depth. Forest soil may have large spatial differences. Taking multiple groups of samples at the same time can help better reflect this difference and improve the representativeness of the samples.

[0003] After searching, the Chinese patent with the authorization announcement number "CN214844145U" provides "a soil sampling device for forestry, which has a simple structure, is easy to use, and can quickly remove the soil from the sampling head after sampling." Although the device can quickly remove the sampled soil from the sampling head, the device can only sample the soil at a certain position at a time, and cannot obtain soil samples at different positions at the same time, and cannot guarantee the reliability and accuracy of the data. Utility Model Content

[0004] The utility model aims to provide a soil sampling device for forestry, which solves the problem in the above background technology that soil samples at different positions cannot be obtained simultaneously and the reliability and accuracy of data cannot be guaranteed.

[0009] Preferably, fixing bolts are provided on both sides of the slide frame, and the fixing bolts penetrate the interior of the slide groove.

[0010] Preferably, the collecting head comprises a collecting bin and a cone head, the collecting bin is detachably connected to the sliding column, and the cone head is fixedly connected to the lower end of the collecting bin.

[0011] Preferably, a plurality of feed slots are provided at the inner outer edge of the collecting bin, and a plurality of guide slots are provided at the outer side of the cone head, and the positions of the guide slots correspond to the feed slots.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A slide is fixedly connected to the inner side of the frame. A plurality of slide grooves are provided on the surface of the slide. The plurality of slide grooves are arranged linearly along the slide. The sampling assembly is placed on the slide, and the fixing bolts are inserted into the slide grooves. A sampling assembly is provided on each set of slide grooves so that multiple sets of soil samples can be collected at the same time to ensure the reliability and accuracy of the data. The sliding frame can adjust the spacing between each set of sampling assemblies according to the specific environment. After the adjustment is completed, the nuts on the fixing bolts are tightened to clamp and fix the sampling assembly to prevent displacement during the sampling process.

[0014] 2. Pressing the pressure handle downward can drive the connecting rod mechanism composed of the main rod and the inner rod to move, and drive the pressure plate to move downward. At the same time, the guide columns fixedly connected at both ends of the pressure plate slide along the inner cavity of the guide cylinder on both sides of the main rod to ensure that the pressure plate can move vertically. The downward pressure plate will cause the sliding column in the sampling assembly to move downward, so that the cone head is inserted into the soil to be sampled, and at the same time, the spring will be compressed. The soil sample will move up along the guide groove opened on the outside of the cone head, and pass through the feeding groove opened at the inner outer edge of the collecting bin at the upper end of the cone head into the collecting bin. Because the soil is sticky, it can remain in the collecting bin. The corresponding guide grooves and feeding grooves can ensure that the soil enters the collecting bin smoothly. After sampling is completed, lift the main rod to move the pressure plate upward. Under the elastic action of the spring, the sliding column is reset and the sampling assembly is separated from the soil layer. The collecting head is removed, and the soil samples in multiple groups of collecting bins are taken out and stored separately for subsequent testing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 As shown, the utility model provides a technical solution: a soil sampling device for forestry, comprising a frame 1 with spikes 11 fixedly connected at both ends of the bottom, a handle 12 fixedly connected at the upper end of the frame 1, the device is moved to a sampling position by the handle 12, and the spikes 11 are inserted into the soil to fix the device.

[0023] A slide 2 is fixedly connected to the inner side of the frame 1. A plurality of slide grooves 21 are provided on the surface of the slide 2. The plurality of slide grooves 21 are linearly arranged along the slide 2. The sampling assembly 3 is placed on the slide 2, and the fixing bolts 311 are inserted into the slide grooves 21. A sampling assembly 3 is correspondingly arranged on each group of slide grooves 21 so that a plurality of groups of soil samples can be collected at the same time to ensure the reliability and accuracy of the data. The sliding slide frame 31 can adjust the spacing between each group of sampling assemblies 3 according to the specific environment. After the adjustment is completed, the nuts on the fixing bolts 311 are tightened to clamp and fix the sampling assembly 3 to prevent displacement during the sampling process.

[0024] The pressing handle 411 can drive the connecting rod mechanism composed of the main rod 41 and the inner rod 42 to move, and drive the pressing plate 43 to move downward. At the same time, the guide columns 431 fixedly connected at both ends of the pressing plate 43 slide along the inner cavity of the guide cylinder 44 on both sides of the main rod 41 to ensure that the pressing plate 43 can move vertically, thereby completing the pressing work of the pressing assembly 4.

[0025] The downward moving pressure plate 43 will cause the sliding column 32 in the sampling assembly 3 to move downward, so that the cone head 342 is inserted into the soil to be sampled, and at the same time, the spring 33 will be compressed. The soil sample will move up along the guide groove 3421 opened on the outside of the cone head 342, and pass through the feeding groove 3411 opened at the inner outer edge of the collecting bin 341 at the upper end of the cone head 342 to enter the collecting bin 341. Because the soil is sticky, it can remain in the collecting bin 341. The corresponding guide groove 3421 and feeding groove 3411 can ensure that the soil enters the collecting bin 341 smoothly. After the sampling is completed, the main rod 41 is lifted to move the pressure plate 43 upward. Under the elastic action of the spring 33, the sliding column 32 is reset and the sampling assembly 3 is detached from the soil layer. The collecting head 34 is removed, and the soil samples in the multiple groups of collecting bins 341 are taken out and stored separately for subsequent testing.
