Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of surveying, in particular to a tool for soil sampling during soil survey. Background Art
[0002] In soil surveys, soil sampling is crucial to the accuracy of the final test data. Existing techniques use simple tools, such as stainless steel shovels, to dig away the soil surrounding the sampled soil, leaving the remaining soil for photographing and sampling. This method inevitably damages the soil cross-section while digging, and the original appearance of the sampling area cannot be guaranteed. Furthermore, manual digging makes it impossible to guarantee the verticality requirements of the sampling area. Utility Model Content
[0003] In order to solve the above technical problems, the purpose of the present utility model is to provide a stable isolation frame, including transverse partitions and longitudinal partitions, both of which are provided with strip grooves, and a through hole is provided at the upper end of the isolation plate. The screws pass through the through holes and strip grooves and cooperate with nuts to connect the isolation plate and the longitudinal partitions or transverse partitions into a whole; the transverse partitions and longitudinal partitions are arranged vertically; convex teeth and grooves are respectively provided at both ends of the transverse partitions and longitudinal partitions, and adjacent transverse partitions and longitudinal partitions are connected by convex teeth and grooves; a hammer plate is provided above the isolation plate; a protrusion is provided above the isolation plate, and the protrusion is embedded in the lower limit groove of the hammer plate.
[0004] Level rulers are provided on the upper surfaces of the transverse and longitudinal partition bars.
[0005] A cutting edge is arranged below the isolation plate, and the inclined surface of the cutting edge is arranged on the outside.
[0006] The isolation plates are composed of multiple pieces, all of which are fixed on the transverse and longitudinal spacers by screws and nuts.
[0007] The advantages of the utility model are: the sampling area can be isolated from the surrounding area by the isolation plate, and the number of isolation plates can be adjusted as needed to meet the requirements of different sampling sizes; since a level ruler is provided, the verticality can be guaranteed, thereby overcoming the defect that the four sides of the sampling area are not vertical.

[0010] Figure 3 for Figure 1 Top view of . DETAILED DESCRIPTION
[0011] The present invention is described in detail below with reference to the accompanying drawings. As shown in the figure, the present invention includes a transverse spacer 1 and a longitudinal spacer 11. The transverse spacer 1 and the longitudinal spacer 11 are both provided with a strip groove 4. A through hole is provided at the upper end of the isolation plate 2. The screw 5 passes through the through hole and the strip groove and cooperates with the nut to connect the isolation plate and the longitudinal spacer or the transverse spacer into a whole; the transverse spacer and the longitudinal spacer are arranged vertically; convex teeth 6 and grooves 7 are respectively provided at both ends of the transverse spacer and the longitudinal spacer, and adjacent transverse spacers and longitudinal spacers are connected by convex teeth and grooves; a hammer plate 3 is provided above the isolation plate; a protrusion 9 is provided above the isolation plate, and the protrusion is embedded in the lower limit groove 12 of the hammer plate 3.
[0012] Level rulers 8 are provided on the upper surfaces of the transverse and longitudinal spacers.
[0013] A cutting edge 10 is provided below the isolation plate, and the inclined surface of the cutting edge is provided on the outside, that is, the inclined surface faces the excavation side, while the sample side remains intact because it is not squeezed.
[0014] The isolation panels are composed of multiple pieces, each with the same structure, and are fixed to the transverse and longitudinal partitions by screws and nuts. This allows for flexible adjustment of the size enclosed by the isolation panels, and even the bottom of the isolation panels can be set into an arc shape as needed.
[0015] The method of using the utility model is as follows: first, the isolation plate is assembled onto the longitudinal partition bar or the transverse partition bar, and then, in the area to be sampled, a rubber hammer is used to hammer the plate to drive the isolation plate into the soil; when hammering the plate, attention should be paid to observing the level ruler to ensure the verticality of the isolation plate; adjacent transverse partition bars and longitudinal partition bars are connected into one body through convex teeth and grooves; then, the soil on the outside (or inside) of the isolation plate is dug away, and finally the isolation plate is removed, leaving the sampling area.
