Description

Technical field:

[0001] The utility model relates to a portable synchronous quantitative collection device for bulk soil and original soil, belonging to the technical field of soil detection in agricultural laboratories. Background technology:

[0002] In agricultural development, soil testing is often necessary. Soil testing often requires obtaining soil through a soil sampler, that is, using a soil sampler to extract and collect samples of the lower soil as test specimens to understand their properties.

[0003] At present, portable soil sampling devices include soil sampling ring cutters, Luoyang shovels, gasoline-powered soil samplers, etc. Gasoline-powered soil samplers use gasoline as power to drive a cylindrical drill to drill into the ground to extract soil, which is difficult to carry and cumbersome to operate. In addition, soil sampling ring cutters, Luoyang shovels, and gasoline-powered soil samplers can only extract original soil, but not loose soil.

[0004] At present, the collection of bulk soil mostly adopts a spiral rotary cutter to destroy the soil layer and transport the soil upward, or uses a shovel to dig layer by layer. Both methods have the disadvantage of destroying the original appearance of the soil layer.

[0005] No matter the above-mentioned original soil collection device or scattered soil collection device, it is impossible to obtain the soil sampling depth data in real time during the soil sampling process.

[0006] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Utility model content:

[0007] The utility model provides a portable synchronous quantitative collection device for loose soil and original soil in order to solve the problems existing in the above-mentioned prior art. The device can take out original soil and loose soil at the same time in one operation, protect the original state of the soil layer, take soil quantitatively in real time, and is convenient for the operator to carry and use, and is easy to disassemble and assemble.

[0008] The technical scheme adopted by the utility model includes: a portable device for synchronous quantitative collection of bulk soil and original soil, comprising an original soil sampling cavity, a left original soil storage cavity, a right original soil storage cavity, a soil sampling depth display rod, a transmission handle, a bulk soil storage cavity and a display rod transmission handle, the left original soil storage cavity and the right original soil storage cavity are installed together, the lower end of the inner wall of the original soil sampling cavity is formed with a clamping groove, the lower ends of the left original soil storage cavity and the right original soil storage cavity are clamped in the clamping groove to clamp the left original soil storage cavity and the right original soil storage cavity. The original soil storage cavity is connected with the original soil extraction cavity, a drilling dragon is welded to the lower end of the outer wall of the original soil extraction cavity, the bulk soil storage cavity is sleeved on the outer side of the original soil extraction cavity and the drilling dragon, the transmission handle is connected to the upper ends of the original soil extraction cavity and the bulk soil storage cavity, the upper end of the soil extraction depth display rod passes through the central through hole of the transmission handle, the lower end of the soil extraction depth display rod passes through the original soil storage cavity, and the display rod transmission handle is connected to the upper end of the soil extraction depth display rod.

[0009] Furthermore, the left original soil storage cavity and the right original soil storage cavity are respectively formed with axial holes in their length directions, and soil storage cavity fixing shafts are installed in the axial holes.

[0010] Furthermore, a plurality of snap-in portions are formed at intervals on the side walls in the length direction of the left original soil storage cavity, and a plurality of snap-in grooves snap-fit ​​with the snap-in portions are formed at intervals on the side walls in the length direction of the right original soil storage cavity, and the left original soil storage cavity and the right original soil storage cavity are connected together by snapping the snap-in portions into the snap-in grooves.

[0011] Furthermore, the length and width of the earth-boring dragon are 1.5 cm and 0.5 cm respectively, and the inclination angle of the earth-boring dragon is 20° to 30°.

[0012] Furthermore, the upper end of the outer side wall of the bulk soil storage cavity is formed with a first external thread, and the lower end of the inner side wall of the transmission handle is formed with a first internal thread matching the first external thread.

[0013] Furthermore, a second external thread is formed at the upper end of the outer side wall of the original soil extraction cavity, and a second internal thread matching the second external thread is formed on the inner side wall of the transmission handle above the first internal thread.

[0014] Furthermore, the upper end of the soil-extracting depth display rod extending beyond the transmission handle is formed with a third external thread, and the lower end of the display rod transmission handle is formed with a third internal thread matching the third external thread.

[0015] Furthermore, the upper end of the outer side wall of the soil sampling depth display rod is engraved with different sizes.

[0016] Furthermore, the upper ends of the inner side walls of the left original soil storage cavity and the right original soil storage cavity are respectively formed with protruding buckles, and in the soil unloading link, the protruding buckles are installed with cavity lifting snaps to extract the original soil.

[0017] Furthermore, a protruding ring is provided on the end of the fixed shaft of the soil storage cavity.

[0018] The utility model has the following beneficial effects:

[0019] (1) By designing a cylindrical bulk soil storage cavity and a soil drilling auger of special length and angle, it is ensured that the external bulk soil is continuously filled in the space enclosed by the bulk soil storage cavity and the soil drilling auger during the soil extraction process, so as to collect the bulk soil. While extracting the soil, it is ensured that the surrounding soil layer does not tilt or collapse. When unloading the bulk soil, the bulk soil storage cavity and the original soil extraction cavity are inverted 180 degrees at the same time while ensuring that they do not move relative to each other.

[0020] (2) The slot-engaged connection designed at the bottom of the original soil storage cavity and the original soil extraction cavity ensures the stability of the original soil storage cavity during the soil drilling stage. By designing two force ports (i.e., protruding buckles) on the upper part of the original soil storage cavity, the original soil storage cavity and the original soil taken from the cavity can be lifted out of the device by cooperating with the force ports when unloading the soil. By lifting the protruding ring at the upper end of the fixed shaft of the soil storage cavity, the left original soil storage cavity and the right original soil storage cavity can be opened to obtain the original soil.

[0021] (3) By designing threaded connections at different positions, the installation and disassembly of the entire device is facilitated. After the soil is taken, the transmission handle can be spirally separated to take out the original soil storage cavity, reverse the bulk soil storage cavity, and pour out the bulk soil.

[0022] (4) By designing a soil-taking depth display rod with different cross-sectional areas at the upper and lower ends, when too much soil is taken, the excess original soil can be pushed out by pushing the display rod transmission handle connected to the top of the soil-taking depth display rod. A scale line is designed on the soil-taking depth display rod. During the soil-taking process, the depth of the soil taken can be displayed in real time through the indication of the scale line above the transmission handle of the soil-taking depth display rod.

[0032] The utility model is further described below in conjunction with the accompanying drawings.

[0033] The utility model discloses a portable synchronous quantitative collection device for bulk soil and original soil, comprising an original soil sampling cavity 1, a left original soil storage cavity 2, a right original soil storage cavity 3, a storage cavity fixed shaft 4, a soil sampling depth display rod 5, a transmission handle 6, a bulk soil storage cavity 7, a display rod transmission handle 8 and a cavity lifting bayonet 9.

[0034] The undisturbed soil sampling cavity 1 is cylindrical as a whole, and two continuous grooves 10 are formed at the lower end of the inner wall of the undisturbed soil sampling cavity 1. The lower ends of the left undisturbed soil storage cavity 2 and the right undisturbed soil storage cavity 3 are fixed in the grooves 10, thereby connecting the left undisturbed soil storage cavity 2, the right undisturbed soil storage cavity 3 and the undisturbed soil sampling cavity 1 together.

[0035] Axial holes (not marked) are formed in the length direction of the left original soil storage cavity 2 and the right original soil storage cavity 3, respectively, and the soil storage cavity fixing shafts 4 are installed in the two axial holes. A plurality of snap-fit ​​parts 20 are formed at intervals on the side wall in the length direction of the left original soil storage cavity 2, and a plurality of snap-fit ​​grooves 30 snap-fit ​​with the snap-fit ​​parts 20 are formed at intervals on the side wall in the length direction of the right original soil storage cavity 3. The left original soil storage cavity 2 and the right original soil storage cavity 3 are connected together by snapping the snap-fit ​​parts 20 into the snap-fit ​​grooves 30. After the left original soil storage cavity 2 and the right original soil storage cavity 3 are assembled, the original soil storage cavity is formed. This connection method can ensure the stability of the original soil storage cavity. The two annular force-bearing designs in the original soil storage cavity facilitate the cooperation of the cavity lifting snap-fit ​​after the soil is taken out to extract the original soil. The upper end of the original soil storage cavity is open.

[0036] A first opening is designed at the bottom of the original soil sampling cavity 1, and 1.5 circles of drilling dragons 11 are welded at the lower end of the outer wall of the original soil sampling cavity 1. The length and width of the drilling dragon 11 are 1.5 cm and 0.5 cm respectively. The inclination angle of the drilling dragon 11 is 20° to 30° to ensure that the degree of soil sliding during the drilling and extraction processes is minimized, meeting the requirements while saving materials.

[0037] The upper and lower ends of the bulk soil storage cavity 7 are both provided with a second opening. The bulk soil storage cavity 7 is sleeved on the outside of the original soil extraction cavity 1 and the drilling dragon 11, so that the bulk soil during the drilling process can be retained in the approximately closed space formed by the drilling dragon 11 and the bulk soil storage cavity 7.

[0038] The upper end of the outer wall of the bulk soil storage cavity 7 is formed with a first external thread, and the lower end of the inner wall of the transmission handle 6 is formed with a first internal thread. The bulk soil storage cavity 7 and the transmission handle 6 are installed together by screwing the first external thread and the first internal thread together.

[0039] A second external thread is formed at the upper end of the outer wall of the original soil extraction cavity 1, and a second internal thread is formed on the inner wall of the transmission handle 6 above the first internal thread. The original soil extraction cavity 1 and the transmission handle 6 are installed together by screwing the second external thread and the second internal thread together.

[0040] The upper and lower ends of the soil depth display rod 5 are designed as cylindrical shafts with different cross-sectional areas. The upper end of the soil depth display rod 5 passes through the central through hole of the transmission handle 6, and the diameter of the upper end is slightly smaller than the diameter of the central through hole of the transmission handle 6 by about 0.5 cm. The upper end extends beyond the top of the transmission handle 6 and is formed with a third external thread (not shown). The lower end of the display rod transmission handle 8 is formed with a third internal thread (not shown). The display rod transmission handle 8 and the soil depth display rod 5 are screwed together by the cooperation of the third external thread and the third internal thread. The lower end of the soil depth display rod 5 passes through the original soil storage cavity and is in direct contact with the original soil, and the diameter of the lower end is slightly smaller than the diameter of the original soil storage cavity by about 0.5 cm. The overall length of the soil depth display rod 5 is about 50 cm.

[0041] The upper end of the outer side wall of the soil extraction depth display rod 5 is engraved with different sizes. When the original soil rises in the original soil storage cavity, the soil extraction depth display rod 5 is lifted up and continuously moved upward. The soil extraction depth information can be obtained in real time by displaying different scales on the part of the transmission handle 6 exposed at the upper end of the soil extraction depth display rod 5. If too much soil is taken, the excess original soil can be pushed out by pushing the display rod transmission handle 8.

[0042] The upper end of the transmission handle 6 adopts a cross-shaped design, and a central through hole with a diameter of 2.5 cm is designed in the middle of the upper end of the transmission handle 6. The center of the central through hole is on the same longitudinal axis as the center of the original soil sampling cavity 1 at the lower end.

[0043] The upper ends of the inner walls of the left original soil storage cavity 2 and the right original soil storage cavity 3 are respectively formed with protrusion buckles 21, so that the original soil can be extracted by installing the cavity lifting clamp 9 on the protrusion buckles 21 during the soil unloading process.

[0044] The bulk soil storage cavity 7 adopts a hollow cylindrical design, which ensures the original appearance of the soil layer during the whole soil extraction process. The lower end of the bulk soil storage cavity 7 is slightly higher than the lower end of the original soil extraction cavity 1 by 5 to 8 cm.

[0045] The portable device for synchronous quantitative collection of loose soil and original soil of the utility model has the following working principle:

[0046] The transmission handle 6 is rotated as a whole through the external rotating device, and the force is transmitted to the soil drilling dragon 11 to rotate and drill the soil, and the whole device moves downward as a whole. The original soil enters the original soil storage cavity, and the bulk soil continuously moves upward through the soil drilling auger 11, and is stored in the closed space formed by the soil drilling auger 11 and the bulk soil storage cavity 7. During the soil drilling process, the original soil continuously moves upward, and the soil extraction depth display rod 5 is continuously lifted up. The part of the upper end of the depth display rod 5 exposed from the transmission handle 6 displays different scales, and the soil extraction depth information can be obtained in real time. If too much soil is taken, the excess original soil can be pushed out by pushing the display rod transmission handle 8.

[0047] After the soil extraction is completed, the entire device is extracted from the soil layer, and then the transmission handle 6 and the display rod transmission handle 8 can be removed by rotating, and the original soil storage cavity can be extracted through the cavity lifting clamp 9, and the left original soil storage cavity 2 and the right original soil storage cavity 3 can be opened by lifting the soil cavity fixed shaft 4 to obtain the original soil, and by simultaneously reversing the bulk soil storage cavity 7 and the original soil extraction cavity 1, the bulk soil retained in this enclosed space is poured into a pre-prepared collection container, thereby completing the simultaneous collection of original soil and bulk soil of equal volume at a fixed depth.

[0048] When the portable device for synchronous quantitative collection of bulk soil and original soil of the utility model is implemented, the lower end of the bulk soil storage cavity 7 is slightly higher than the lower end of the original soil sampling cavity 1, ensuring the normal descent of the device as a whole. The outer wall of the bulk soil storage cavity 7 adopts a cylindrical design to ensure that the soil layer will not collapse or tilt due to the soil sampling operation of the device, thereby ensuring the original appearance of the soil layer.

[0049] When the portable synchronous quantitative collection device for bulk soil and original soil of the utility model is implemented, after the left original soil storage cavity 2 and the right original soil storage cavity 3 are connected together, the lower end cooperates with the slot designed at the lower end of the original soil extraction cavity 1 to ensure the stability of the original soil storage cavity during the soil extraction process. The upper ends of the left original soil storage cavity 2 and the right original soil storage cavity 3 are each designed with a protruding buckle 21, which is convenient for the force of the cavity lifting snap 9 in the later stage, so as to lift the original soil storage cavity. The upper end of the soil storage cavity fixed shaft 4 is designed with a protruding ring 40 to provide a force point to provide a guarantee for opening the original soil storage cavity.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
