Description

Technical Field

[0001] The utility model relates to the technical field of soil survey, in particular to a soil survey paper box specimen sampling device. Background Art

[0002] Soil survey is an important method to identify soil types and distribution patterns, and to ascertain the quantity and quality of soil resources. The survey results can provide scientific support for the scientific classification, planned utilization, improvement and fertilization, protection and management of soil, and can also provide a basis for the formulation of major policies for economic, social and ecological construction.

[0003] In the third national soil survey profile survey, it is necessary to collect paper box specimens at the profile points. The soil layer samples are collected in the order of the profile layers, from bottom to top. The traditional method is to use a knife to slowly cut the soil into cut soil. Some profile points are divided into 5 layers, and 5 soil blocks need to be cut. Especially for national control points, if a profile point is divided into 5 layers, 4 paper box specimens need to be collected, and 20 soil blocks need to be cut, which is very time-consuming.

[0004] When cutting soil with a knife, soil lumps are easy to scatter. In addition, each person has different ways of cutting soil, so the soil lumps cut out may be too large or too small to meet the requirements, which delays the field operation time. Therefore, manual soil cutting operation takes a long time and the results are difficult to control. What's more serious is that for hard soil layers or when the soil layer is frozen in the cold winter, the knife cannot be inserted into the soil layer, and manual soil cutting cannot be completed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a soil survey paper box specimen sampling device, which can smoothly implement soil cutting sampling regardless of hard soil layers or frozen soil layers, and the standard soil specimen cut pieces are placed just in the box grid, and the device is easy to operate, has reliable quality, and has high soil sampling efficiency.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The utility model comprises a soil cutting unit and a bulldozer unit arranged inside the soil cutting unit, the soil cutting unit comprises a soil cutting block with a bottom opening and a cutting knife arranged at the bottom of the soil cutting block, the bulldozer unit comprises a push plate arranged in the soil cutting block and a push rod fixed to the push plate, the push rod passes through a top plate and is movably arranged in a sleeve, and the sleeve is fixed to the top plate of the soil cutting block.

[0008] A further improvement of the utility model is that both the sleeve and the push rod are provided with positioning holes, and positioning screws passing through the positioning holes fix the sleeve and the push rod, and the push plate and the top plate are clamped and fixed together.

[0009] A further improvement of the utility model is that the sleeve is connected to a handle, the handle comprises a main handle and a secondary handle connected to the main handle via a connecting rod, and the secondary handle is fixed to the top end of the sleeve.

[0010] A further improvement of the utility model is that the top of the push rod is fixed to the push handle, and the push handle is movably arranged between the main handle and the auxiliary handle.

[0011] A further improvement of the utility model is that the soil cutting block is a rectangular block, including a rectangular top plate and side plates, a front plate and a rear plate connected to the four sides of the top plate, the ends of the side plates, the front plate and the rear plate are provided with blades, the blades are combined into a cutting knife consistent with the shape of the box grid, and the depth of the box grid is consistent with the depth of the soil cutting block.

[0012] A further improvement of the utility model is that the soil specimens cut by the cutter are placed in the box grid of the paper box.

[0013] A further improvement of the utility model is that a flip-over box cover is provided on one side of the box, and a marking label is correspondingly provided on the other side of the box, and the marking label records the information of the soil sample in the box.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are:

[0015] The utility model has the advantages of simple structure and novel design. The soil blocks can be directly cut out into soil specimens with the same size and shape as the box grid. The soil cutting quality is reliable, the soil cutting efficiency is high, and the soil specimen sampling time is greatly shortened.

[0016] The soil cutting block is made of steel plate. The blade of the cutter is sharp and convenient for cutting soil. It is suitable for all kinds of soil, especially for clay sampling. Because clay is particularly hard, it cannot be cut manually with a knife, and it is impossible to complete the soil cutting. This device can perfectly solve the problem. Using this device, the soil samples taken out are of the same size and meet the relevant regulations and standards. It effectively avoids the trouble of different sizes of soil blocks cut out and no fixed standards due to different soil cutting techniques of each person.

[0017] The setting of the handle is not only convenient for carrying, but also conducive to cutting soil. During the soil cutting process, the cutter can be pressed down by pressing the handle, especially for hard soil layers, and the handle can be hit with a rubber hammer to slowly drive the cutter into the soil layer to complete the soil cutting.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] A soil survey paper box specimen sampling device, such as Figure 1-Figure 4 As shown, it includes a soil cutting unit and a pusher unit arranged inside the soil cutting unit. After the soil cutting unit completes soil cutting, the pusher unit pushes the soil sample cut from the soil cutting block 8 into the box 12 to complete sampling. The soil cutting block 8 corresponds to the size and shape of the box 12, ensuring that the soil sample cut by the cutter 8-4 is just filled into the box 12 for collecting the soil sample in the paper box.

[0025] like Figure 1-Figure 3 As shown, the soil cutting unit includes a soil cutting block 8 with an opening at the bottom and a cutter 8-4 arranged at the bottom of the soil cutting block 8. The cutter 8-4 is provided with a sharp blade to cut the soil at each cross-section sampling point to collect soil samples. The soil cutting block 8 is made of steel plate, which is strong and durable, does not deform, and has a long service life. The soil sample cut by the cutter 8-4 is stored in the soil cutting block 8, and then pushed into the box 12 by the bulldozer unit for storage.

[0026] like Figure 2 and Figure 3 As shown, the bulldozer unit includes a push plate 9 disposed in the soil cutting block 8 and a push rod 5 fixed to the push plate 9, and the push rod 5 pushes the push plate 9 downward to achieve bulldozing. The push rod 5 passes through the top plate 8-1 and is movably disposed in the sleeve 7, and the sleeve 7 is fixed to the top plate 8-1 of the soil cutting block 8. After the soil cutting is completed, the push plate 9 is pushed by the push rod 5 to completely push the soil sample in the soil cutting block 8 into the box 12. The setting of the push plate 9 facilitates the complete pushing of the cut soil sample into the box 12. This eliminates the problem that different soil cutting techniques cut out soil blocks of different sizes during the manual soil cutting process, resulting in soil samples of different sizes and no fixed standard.

[0027] The sleeve 7 and the push rod 5 are both provided with positioning holes 10, and the positioning screws 6 passing through the positioning holes 10 fix the sleeve 7 and the push rod 5 to achieve the positioning of the push rod 5 and the sleeve 7. At this time, during the soil cutting process, Figure 2 As shown, the push plate 9 is clamped and fixed with the top plate 8-1. When the soil cutting is completed and the soil sample in the soil cutting block 8 needs to be pushed into the box 12, the positioning screw 6 is pulled out from the positioning hole 10, and then the push rod 5 is pushed downward, and the push rod 5 pushes the push plate 9, and the push plate 9 is pushed from the top of the soil cutting block 8 as shown in FIG. Figure 2 Move to the bottom of the cutting block 8 as shown in Figure 3 The soil specimen cut in the soil cutting block 8 is smoothly pushed into the box 12. After the soil is pushed, the push rod 5 is lifted, and the positioning screw 6 is inserted into the positioning hole 10, so that the push plate 9 is fixed with the top plate 8-1, and the next soil cutting is prepared.

[0028] The sleeve 7 is connected to a handle, and the handle includes a main handle 1 and a sub-handle 3 connected to the main handle 1 through a connecting rod 2, and the sub-handle 3 is fixed to the top of the sleeve 7. During the soil cutting process, the main handle 1 can be operated to press down the cutter 8-4 to insert it into the soil to collect soil samples. When the soil is hard and the cutter cannot be inserted into the soil to collect the sample, a rubber hammer can be used to knock down the main handle 1 until the cutter 8-4 is inserted into the soil to complete the collection of the soil sample. Therefore, whether it is hard clay or frozen soil containing an ice layer, it will not affect the smooth implementation of soil sample sampling.

[0029] The top of the push rod 5 is fixed to the push handle 4, and the push handle 4 is movably arranged between the main handle 1 and the auxiliary handle 3. For the convenience of operation, after the soil cutting is completed and the soil sample is cut into the cut soil block 8, when it needs to be pushed into the box 12, the push handle 4 can be operated to move the push rod downward to realize the push plate 9 moving from the top of the cut soil block 8 to the bottom, and the soil sample collected in the cut soil block 8 can be smoothly moved to the box 12 for storage.

[0030] The device replaces manual soil cutting and sampling, is not only suitable for collecting soil samples of all hardness soils, but also has the same size of collected soil samples, and can be smoothly stored in the box 12. It is simple to operate, convenient to sample, and easy to carry, suitable for collecting all soil samples, and greatly improves work efficiency.

[0031] The soil cutting block 8 can be set as a rectangular parallelepiped or a cylindrical shape. The following is a detailed description using a rectangular parallelepiped as an example. Figure 1-Figure 3 As shown, the soil cutting block 8 comprises a rectangular top plate 8-1 and side plates 8-2, a front plate 8-3 and a rear plate connected to the four sides of the top plate 8-1. The ends of the side plates 8-2, the front plate 8-3 and the rear plate are provided with blades, which are combined into a rectangular cutter 8-4 in the same shape as the box grid 12. The depth of the box grid 12 is consistent with the depth of the soil cutting block 8. It is ensured that the soil sample cut from the soil cutting block 8 is just filled into the box grid 12 of the paper box.

[0032] like Figure 4As shown, the soil sample cut by the cutter 8-4 is placed in the box 12 of the paper box, and a reversible box cover 11 is provided on one side of the box 12, and a label 13 is provided on the other side of the box 12. The label 13 records the information of the soil sample in the box 12. The label 13 records the layer, upper and lower boundary depths of the soil layer represented by the soil sample in the corresponding box 12, and the box cover 11 is filled with the sample point number, location, terrain, layer depth, collection time, collector and other information as required. After the sampling is completed and completely placed in the box 12, the box cover 11 is closed and tied tightly with a rubber band to prevent the soil sample in the box 12 from being loose and scattered, and then it is transported to the designated location.

[0033] During use, first lift the push handle 4, then insert the positioning screw 6 into the positioning hole 10, retract the push rod 5 and fix it with the sleeve 7, align the rectangular cutter 8-4 with the corresponding soil taking position, hold the sleeve 7 with the left hand, and use the rubber hammer with the right hand to knock the main handle 1 until the cutter 8-4 is inserted into the soil layer to a depth of about 3 cm. When the push plate 9 is flush with the cut soil surface, stop knocking and the soil cutting is completed.

[0034] Then use a shovel to completely dig out the cutter 8-4 and the soil blocks about 2 cm around it to prevent the bottom surface from being uneven and having holes. Then slowly remove the excess soil on the bottom surface to make the internal soil blocks flush with the surrounding areas. Finally, pull out the positioning screw 6, operate the push handle 4 to make the push rod 5 drive the push plate 9 to move downward, slowly push out the soil sample cut from the cut soil block 8 and put it into the corresponding box grid 12 of the paper box, and the sampling is completed.

[0035] Finally, it should be noted that the above embodiments are only examples for the purpose of clearly explaining the present invention, and are by no means limiting of the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here, and the obvious changes or modifications derived from them still fall within the scope of protection of the present invention.
