Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a compression-type soil density measuring device. Background Technology

[0002] Soil density is an important indicator reflecting the physical properties of soil, referring to the ability of a unit volume of soil to resist compression under external forces. It directly affects crop root development, water infiltration, and nutrient cycling. Traditional testing methods often use manual rod insertion or pressure plate methods, which suffer from problems such as rough operation and discrete data. However, modern agriculture has an increasingly urgent need for precise measurement, requiring a device that can standardize the testing process and quantify soil compressive strength.

[0003] Existing soil density testing devices rely on heavy machinery for pressure application, which makes them inconvenient to move in the field and cumbersome to disassemble and assemble. This results in troublesome disassembly and cleaning after each soil measurement, and the accuracy of the results is easily affected by operational errors. Therefore, a compression-type soil density measuring device is provided to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenience in movement and operation in the existing technology, and to propose a compression-type soil density measuring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A compression-type soil density measuring device includes a support assembly, a lifting drive component installed on the support assembly, a pressing component installed at the bottom of the lifting drive component, a bottom support component engaged on the bottom of the inner wall of the support assembly, and side positioning components installed around the top of the bottom support component.

[0007] The four side positioning members are interlocked in a ring, and the pressing component is located directly above the bottom support.

[0008] Preferably, the support assembly includes a main support base, with side support brackets installed on both sides of the top of the main support base, and side support rods installed on each of the two side support brackets. A threaded support base is provided above the main support base, and the bottom of the threaded support base is fixed to the top of the two side support rods.

[0009] Preferably, the lifting drive component includes a threaded rod, an auxiliary bracket is rotatably connected to the threaded rod, the threaded rod is threadedly connected to a threaded support seat, a lifting seat is rotatably connected to the bottom end of the threaded rod, the two ends of the lifting seat are slidably connected to side support rods, and the two ends of the bottom of the auxiliary bracket pass through the threaded support seat and are connected to the top of the lifting seat.

[0010] Preferably, a drive gear is rotatably connected to the auxiliary bracket, a driven gear is mounted on the top of the threaded rod, the driven gear meshes with the drive gear, and a rotating handle is mounted on the top of the drive gear.

[0011] Preferably, the pressing assembly includes a pressing frame, the top of which is connected to a lifting drive component, and a pressing plate is attached to the bottom of the pressing frame. Multiple positioning screws are threaded onto the pressing frame, and the pressing frame is connected to the top of the pressing plate via the multiple positioning screws.

[0012] Preferably, a signal transmitter is installed on the lower pressure frame, and a pressure detector is installed on the bottom of the lower pressure plate. The signal output terminal of the pressure detector is connected to the signal input terminal of the signal transmitter.

[0013] Preferably, the bottom support includes a base plate, a locking block is installed at the bottom of the base plate, the base plate is connected to the top of the main support base through the locking block, a plurality of support blocks are slidably connected on the base plate, each support block has a plurality of insertion holes, the plurality of support blocks engage with the adjacent side positioning components through the insertion holes, positioning blocks are installed on the four sides of the locking block, handles are installed on the plurality of support blocks, insertion rods are inserted into the plurality of handles, and the plurality of insertion rods sequentially pass through the adjacent handles and positioning blocks.

[0014] Preferably, the side positioning component includes a side plate, one side of which has a locking groove, and the other side of which has a locking block. A bottom insertion tube is installed at the bottom of the side plate, and the side plate engages with the insertion hole on the adjacent support block through the bottom insertion tube.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. The main structure of the device, consisting of the support components and the lifting drive components, adopts a U-shaped frame. Together with the pressing components, it forms a stable mechanical system. It can quickly gather and fix the soil sample through the side positioning components, and can also achieve uniform pressure on the pressing plate through the precision transmission of the threaded rod. The pressure detector transmits data to the researchers in real time. The design of the bottom support components' locking blocks and insertion rods, the locking structure of the side positioning components, and the replaceable components make the device both adaptable and easy to maintain. Disassembly and assembly only require simple plug-and-play operations, which significantly improves the detection efficiency and makes cleaning easier after disassembly.

[0017] 2. This device amplifies torque through the meshing of the driving and driven gears, enabling the threaded rod to be smoothly raised and lowered with a slight rotation of the handle. This reduces operational intensity while ensuring measurement accuracy. The vertical conical support structure of the lower pressure frame, in conjunction with the positioning screws, ensures uniform and stable force distribution on the lower pressure plate. The adjustable side plates and lower pressure plate can flexibly adapt to the needs of soil testing in different areas. The dual guide design of the auxiliary support and the lifting seat further ensures the stability of the threaded rod's movement. Through mechanical coordination and humanized design, the entire device achieves efficient operation throughout the entire process, from sample fixation and pressure testing to data output.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figure 1-4As shown, this utility model provides a compression soil density measuring device, including a support component 1, a lifting drive component 2 installed on the support component 1, a pressing component 3 installed at the bottom of the lifting drive component 2, a bottom support component 4 engaged on the bottom of the inner wall of the support component 1, and side positioning components 5 installed around the top of the bottom support component 4.

[0026] Among them, the four side positioning parts 5 are interlocked in a ring, and the pressing component 3 is located directly above the bottom support part 4.

[0027] In this embodiment, the support assembly 1 includes a main support base 11, with side support brackets 12 installed on both sides of the top of the main support base 11, and side support rods 14 installed on both side support brackets 12. A threaded support base 13 is provided above the main support base 11, and the bottom of the threaded support base 13 is fixed to the top of the two side support rods 14.

[0028] Within the support assembly 1, the main support base 11, side support frame 12, threaded support base 13, and side support rod 14 form a U-shaped support structure. A lifting drive component 2 is added to this structure to establish the connection between the support assembly 1 and the pressing assembly 3.

[0029] In this embodiment, the lifting drive component 2 includes a threaded rod 25, an auxiliary bracket 23 rotatably connected to the threaded rod 25, the threaded rod 25 being threadedly connected to the threaded support seat 13, a lifting seat 26 rotatably connected to the bottom end of the threaded rod 25, and two ends of the lifting seat 26 being slidably connected to the side support rod 14. Both ends of the bottom of the auxiliary bracket 23 pass through the threaded support seat 13 and are connected to the top of the lifting seat 26. A drive gear 22 is rotatably connected to the auxiliary bracket 23, and a driven gear 24 is installed on the top of the threaded rod 25. The driven gear 24 meshes with the drive gear 22, and a rotating handle 21 is installed on the top of the drive gear 22.

[0030] The threaded rod 25 serves as the main rotating component. When the threaded rod 25 rotates, under the limitation of the side support rod 14, the threaded rod 25 drives the lifting seat 26 to descend through the threaded connection with the threaded support seat 13. Thus, the descent of the threaded rod 25 drives the descent of the pressing component 3. The rotation of the threaded rod 25 relies on the rotation of the driven gear 24. By rotating the handle 21, the driving gear 22 can be driven to rotate. Because the driving gear 22 meshes with the driven gear 24, the rotation of the handle 21 can drive the rotation of the driven gear 24. Furthermore, due to the presence of the driving gear 22 and the driven gear 24, the rotation of the threaded rod 25 is not directly driven by the handle 21. This achieves a more precise and labor-saving rotation method by using a small wheel to drive a large wheel. The addition of the auxiliary bracket 23 can support the driving gear 22 and also assist the lifting seat 26 in stabilizing the lifting of the threaded rod 25.

[0031] In this embodiment, the pressing assembly 3 includes a pressing frame 31. The top of the pressing frame 31 is connected to the lifting drive 2, and the bottom of the pressing frame 31 is attached to a pressing plate 32. Multiple positioning screws 33 are threaded onto the pressing frame 31. The pressing frame 31 is connected to the top of the pressing plate 32 through the multiple positioning screws 33. A signal transmitter 35 is installed on the pressing frame 31, and a pressure detector 34 is installed at the bottom of the pressing plate 32. The signal output terminal of the pressure detector 34 is connected to the signal input terminal of the signal transmitter 35.

[0032] The lower pressure frame 31 and the lower pressure plate 32 cooperate and are connected by the positioning screw 33 to achieve a stable connection effect. The size of the lower pressure plate 32 can be selected according to the area enclosed by the actual side positioning part 5. The lower pressure frame 31 adopts a vertical conical support, which can make the lower pressure plate 32 more stable under force. Finally, after cooperating with the side positioning part 5 and measuring the pressure through the pressure detector 34, the data is transmitted to the researchers through the signal transmitter 35 to determine the compaction of the soil.

[0033] In this embodiment, the bottom support 4 includes a base plate 41, a locking block 42 is installed at the bottom of the base plate 41, the base plate 41 is connected to the top of the main support base 11 through the locking block 42, a plurality of support blocks 44 are slidably connected on the base plate 41, each support block 44 is provided with a plurality of insertion holes 47, the plurality of support blocks 44 are engaged with the adjacent side positioning members 5 through the insertion holes 47, positioning blocks 43 are installed on the four sides of the locking block 42, handles 45 are installed on the plurality of support blocks 44, and insertion rods 46 are inserted into the plurality of handles 45, the plurality of insertion rods 46 sequentially pass through the adjacent handles 45 and positioning blocks 43.

[0034] The base plate 41 serves as the main body and is connected to the main support base 11 via the locking block 42. This allows the main support base 11 to position the locking block 42 while facilitating the removal of the bottom support member 4. The addition of the support block 44, through the insertion hole 47 on the support block 44, maintains the connection with the side positioning member 5. The handle 45 allows the support block 44 to be easily pulled out from the base plate 41. The insertion rod 46 and the positioning block 43 can establish a connection between the positioning block 43 and the handle 45 after the support block 44 is inserted into the base plate 41, thereby improving the stability of the bottom support member 4 in positioning the side positioning member 5.

[0035] In this embodiment, the side positioning component 5 includes a side plate 51. A locking groove 52 is provided on one side of the side plate 51, and a locking block 53 is installed on the other side of the side plate 51. A bottom insertion tube 54 is installed at the bottom of the side plate 51, and the side plate 51 is engaged with the insertion hole 47 on the adjacent support block 44 through the bottom insertion tube 54.

[0036] The bottom of the four side plates 51 is fixed by inserting the bottom tube 54 into the corresponding two holes 47 on the support block 44. The side plates are fixed by the engagement groove 52 and engagement block 53. The four side plates 51 are arranged in a ring and engage with each other to form an open structure at the top together with the bottom support 4. The side plates 51 with different widths and the pressure plates 32 with different areas can be replaced to adapt to soil density measurement of different areas. Disassembly and assembly only require longitudinal engagement and disassembly, which is convenient and quick.

[0037] Furthermore, the pressure detector 34 can measure pressure data by contacting the soil and transmit the data through the signal transmitter 35. The specific model and size can be selected according to the actual use environment.

[0038] How to use and how to work this device:

[0039] When in use, the support component 1 and the lifting drive component 2 serve as the main components. The support component 1 supports the bottom support component 4 and the side positioning component 5. The pressing component 3 supports the lifting drive component 2. After the soil is placed on the bottom support component 4, it is gathered by the side positioning component 5 and finally squeezed by the pressing component 3. The pressing component 3 is used to obtain the final soil compaction data. The installation and disassembly are relatively convenient, and it is easy to maintain and clean the soil.

[0040] Within the support assembly 1, the main support seat 11, the side support frame 12, the threaded support seat 13, and the side support rod 14 form a U-shaped support structure. On this structure, a lifting drive component 2 is added to establish the connection between the support assembly 1 and the pressing assembly 3.

[0041] Within the lifting drive component 2, the threaded rod 25 serves as the main rotating component. When the threaded rod 25 rotates, under the limitation of the side support rod 14, the threaded rod 25 drives the lifting seat 26 to descend through the threaded connection with the threaded support seat 13. Thus, the descent of the threaded rod 25 drives the descent of the pressing component 3. The rotation of the threaded rod 25 relies on the rotation of the driven gear 24. By rotating the handle 21, the driving gear 22 can be driven to rotate. Because the driving gear 22 meshes with the driven gear 24, the rotation of the handle 21 can drive the rotation of the driven gear 24. Furthermore, due to the presence of the driving gear 22 and the driven gear 24, the rotation of the threaded rod 25 is not directly driven by the handle 21. This achieves a more precise and labor-saving rotation method by using a small wheel to drive a large wheel. The addition of the auxiliary bracket 23 can support the driving gear 22 and also assist the lifting seat 26 in stabilizing the lifting of the threaded rod 25.

[0042] The lower pressure frame 31 and the lower pressure plate 32 cooperate within the lower pressure assembly 3 and are connected by the positioning screw 33 to achieve a stable connection effect. The size of the lower pressure plate 32 can be selected according to the area enclosed by the actual side positioning component 5. The lower pressure frame 31 adopts a vertical conical support, which can make the lower pressure plate 32 more stable under force. Finally, after cooperating with the side positioning component 5 and measuring the pressure through the pressure detector 34, the data is transmitted to the researchers through the signal transmitter 35 to determine the compaction of the soil.

[0043] Inside the bottom support 4, the base plate 41 serves as the main body. It is connected to the main support base 11 through the locking block 42. This allows the main support base 11 to position the locking block 42 while facilitating the removal of the bottom support 4. The support block 44 is added, and the connection with the side positioning member 5 is maintained through the insertion hole 47 on the support block 44. The handle 45 allows the support block 44 to be easily pulled out from the base plate 41. The insertion rod 46 and the positioning block 43 can establish a connection between the positioning block 43 and the handle 45 after the support block 44 is inserted into the base plate 41, which improves the stability of the bottom support 4 in positioning the side positioning member 5.

[0044] Inside the side positioning component 5, the bottom of the four side plates 51 is fixed by inserting the bottom insertion tube 54 into the corresponding two insertion holes 47 on the support block 44. The side fixing is achieved by the cooperation of the locking groove 52 and the locking block 53. The four side plates 51 are arranged in a ring and locked together with each other, forming an open structure at the top together with the bottom support component 4. The side plates 51 with different widths and the lower pressure plate 32 with different area sizes can be replaced to adapt to soil density measurement of different areas. Disassembly and assembly only require longitudinal locking and plugging, which is convenient and quick to operate.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
