Description

Technical Field

[0001] This utility model relates to the field of soil testing and sampling technology, and in particular to a soil testing and sampling device. Background Technology

[0002] Soil pollution is a type of environmental pollution that has a serious impact on crop production and people's lives. In order to test the soil, soil sampling devices are needed to collect soil samples.

[0003] CN220170570U discloses a handheld soil sampling device, including a mounting bracket, handrail brackets on both sides of the mounting bracket, a drive motor arranged on the mounting bracket, a transmission rod coaxially connected to the motor shaft of the drive motor, and a drill bit disposed at the end of the transmission rod for collecting soil. The drive motor is started by a gasoline generator and includes a mounting bracket, a drive component fixedly mounted on the mounting bracket, a transmission rod coaxially connected to the output shaft of the drive component, and a drill bit disposed at the end of the transmission rod. Handrail brackets are provided on both sides of the mounting bracket, and a support assembly is also provided on the mounting bracket for support. The assembly includes telescopic rods symmetrically arranged on both sides of the mounting bracket, and a support frame connected to the end of the telescopic rods away from the mounting bracket and used to abut against the soil surface. The telescopic rods include a first support rod and a second support rod slidably connected to the first support rod. One end of the first support rod is fixedly connected to the mounting bracket, and the other end of the first support rod has a sliding chamber for the second support rod to slide axially. The depth of the sliding chamber is the same as the length of the drill bit. The first support rod has a limiting surface formed on the top wall of the sliding chamber for the end of the second support rod to abut against. The end of the second support rod away from the first support rod has a mounting screw hole. The top surface of the support plate is provided with a mounting stud for the mounting screw hole to mate with.

[0004] The specific working principle of the handheld soil sampling device disclosed in the aforementioned publication number CN220170570U is as follows: when conducting soil sampling, the drill bit is placed against the soil surface, the drive motor is started, the sampling personnel hold the handrail support and press down, and as the drill bit rotates, it extends downward into the soil surface. After the drill bit enters a certain depth, the entire soil sampling device is lifted up, and the soil can rise synchronously with the drill bit to complete the sampling.

[0005] Because its drive unit, mounting bracket, and handrail bracket are all located at the top, while existing handheld soil testing and sampling devices have a vertical and elongated structure, they become top-heavy. This causes the entire structure to sway during soil sampling, which greatly reduces the anti-shaking stability of the soil testing and sampling device.

[0006] Therefore, we designed a handheld soil testing and sampling device to meet the needs of practical applications. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a soil testing and sampling device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: Design a soil testing and sampling device, including a device frame, on which a telescopic rod and a drive motor are mounted. A transmission rod is mounted on the motor shaft of the drive motor, and a drill bit is mounted on the transmission rod. A support frame is mounted on a pre-set slide rod of the telescopic rod. The drill bit is rotatably slidably connected to the support frame. The device frame is provided with a side fixing plate and a welding block. A shaft hole is opened on the side fixing plate, and a rotating shaft is rotatably mounted in the shaft hole. A sleeve is mounted on the rotating shaft, and a sliding support rod is slidably connected in the sleeve. An internal threaded tube is mounted on the sliding support rod, and a stud is mounted on the internal threaded tube. An anti-sway support plate is mounted on the stud, and an anti-sway support plate is provided with an anti-slip pad and a groove. A locking rod is slidably connected to the welding block, and a rod cap is provided on the locking rod, with a spring provided on the rod cap; The sleeve is provided with a screw pin, the device frame is provided with a handrail bracket, and the handrail bracket is provided with a lifting frame.

[0009] In detail, the armrest supports are two symmetrically arranged on the left and right, and the lifting frame is U-shaped and is located at the upper end of the two armrest supports.

[0010] In detail, the two ends of the spring are fixedly mounted to the welding block and the rod cap, respectively, and the rotating shaft is provided with a first locking groove and a second locking groove.

[0011] In detail, the fixed screw is threaded to the side wall of the sleeve, the sliding support rod is provided with a first groove and a second groove, and the outer end of the fixed screw is provided with a rotating handle, which is generally diamond-shaped.

[0012] In detail, the stud is threaded to the pre-set threaded groove on the inner threaded tube, and the threaded groove is a semi-circular groove with eight grooves arranged in a circle.

[0013] In detail, the anti-sway support plate is a disc-shaped structure, and the anti-slip pad is set on the lower end surface of the anti-sway support plate.

[0014] In detail, the rotating shafts are two symmetrical shafts located on the outer side wall of the sleeve, and the outer wall surface of the rotating shafts is provided with baffles.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model features a sleeve with a sliding positioning support rod structure on the device frame, along with a vertical spring snap-fit ​​structure. An internal threaded tube with a stud is installed on the support rod, and an anti-sway support plate structure with an anti-slip pad is then installed on the stud. Before soil sampling, the four sleeves can be rotated and locked in position, then the support rod can be slid in position, and finally the anti-sway support plate can be adjusted to ensure stable contact and support between the anti-slip pad and the soil surface. This allows for subsequent soil sampling operations, achieving stable anti-sway support on all four sides of the device frame, thus improving the overall anti-sway stability of the soil testing and sampling device during soil sampling.

[0016] 2. This utility model, by setting a lifting frame on the handrail support and setting a sleeve and sliding support rod with a foldable, retractable positioning and locking structure, allows the four sets of sleeves and sliding support rods to be folded, retracted and positioned and locked together when the entire device frame is carried to the location where soil sampling is required. Then, one hand can directly hold the lifting frame to easily lift the entire device frame to the location where soil sampling is required, which greatly improves the portability and ease of carrying the soil testing and sampling device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-6 A soil testing and sampling device includes a device frame 1, on which a telescopic rod 10 and a drive motor 2 are mounted. A transmission rod 21 is provided on the motor shaft of the drive motor 2, and a drill bit 22 is provided on the transmission rod 21. A support frame 23 is provided on the preset slide rod of the telescopic rod 10. The drill bit 22 is rotatably slidably connected to the support frame 23. A side fixing plate 3 and a welding block 4 are provided on the device frame 1. A shaft hole 31 is opened on the side fixing plate 3. A rotating shaft 5 is rotatably arranged in the shaft hole 31. A sleeve 51 is provided on the rotating shaft 5. A sliding support rod 7 is slidably connected in the sleeve 51. An inner threaded tube 8 is provided on the sliding support rod 7. A stud 81 is provided on the inner threaded tube 8. An anti-sway support plate 9 is provided on the stud 81. An anti-sway support plate 9 is provided with an anti-slip pad 92 and a buckle groove 91. A locking rod 41 is slidably connected to the welding block 4, and a rod cap 42 is provided on the locking rod 41. A spring 43 is provided on the rod cap 42. A screw pin 6 is set on the sleeve 51, a handrail bracket 11 is set on the device frame 1, and a lifting frame 12 is set on the handrail bracket 11. The telescopic rod 10, handrail bracket 11, drive motor 2, transmission rod 21, drill bit 22, and support frame 23 described in this patent are all related structures of the handheld soil sampling device disclosed in publication number CN220170570U, which are prior art. Some existing structures are not drawn or labeled, so there is no need to elaborate.

[0021] It should be further noted that there are two symmetrical armrest supports 11, and the lifting frame 12 has a U-shaped structure and is located at the top of the two armrest supports 11.

[0022] It should be further noted that the two ends of the spring 43 are fixedly set to the welding block 4 and the rod cap 42 respectively, and the rotating shaft 5 is provided with a first locking groove 52 and a second locking groove 53. The spring 43 is made of high-quality spring steel, which is highly elastic and stable.

[0023] It should be further explained that the fixed screw 6 is threadedly connected to the side wall of the sleeve 51. When the fixed screw 6 is removed from the first slot 71 or the second slot 72, the fixed screw 6 is still threadedly connected to the side wall of the sleeve 51 to prevent the fixed screw 6 from being lost.

[0024] The sliding support rod 7 has a first slot 71 and a second slot 72. The outer end of the fixed screw pin 6 is provided with a handle 61. The handle 61 has a diamond-shaped structure and can be directly and conveniently held by the fingers and rotated.

[0025] It should be further explained that the stud 81 is connected to the pre-set threaded groove on the inner threaded tube 8. The snap groove 91 is a semi-circular groove with eight grooves arranged in a circle. The stud 81 can be easily rotated by inserting a finger to adjust its up and down position, so as to ensure that the lower end of the anti-slip pad 92 makes stable contact with the soil surface for support.

[0026] It should be further noted that the anti-sway support plate 9 has a disc-shaped structure, and the anti-slip pad 92 is set on the lower end surface of the anti-sway support plate 9. The anti-slip pad 92 is made of vulcanized rubber, which has damping and anti-slip properties, and is wear-resistant and corrosion-resistant.

[0027] It should be further explained that there are two symmetrical rotating shafts 5 on the outer side wall of the sleeve 51. The outer wall surface of the rotating shaft 5 is provided with baffles 50. When the rotating shaft 5 rotates in the shaft hole 31, the baffles 50 on both sides prevent the rotating shaft 5 from slipping.

[0028] Working method: Before sampling the soil, refer to Figure 3 First, pull the cap 42 upwards, causing the locking rod 41 to slide upwards and exit the second locking groove 53. At this time, the spring 43 is stretched and deformed. Next, rotate the sleeve 51 outwards forty-five degrees to position it. Then, release the cap 42. The spring 43 pulls back and causes the locking rod 41 to slide downwards and quickly engage in the first locking groove 52. Next, turn the handle 61 counterclockwise, causing the fixed screw pin 6 to rotate counterclockwise. Through the thread transmission between the fixed screw pin 6 and the pre-set screw hole on the side wall of the sleeve 51, the fixed screw pin 6 rotates and exits the second locking groove 72. Then, slide the sliding support rod 7 out. Then, turn the handle 61 clockwise again to rotate the fixed screw pin 6 and engage it in the first locking groove 71. See Figure 2 and Figure 5 Then, insert your finger into the groove 91 and rotate it counterclockwise, causing the stud 81 to rotate counterclockwise. Through the threaded transmission between the stud 81 and the preset inner groove on the inner tube 8, the stud 81 and the anti-slip pad 92 can be moved downward as a whole. When the lower end of the anti-slip pad 92 is in stable contact with the soil surface, stop rotating the stud 81. Soil sampling can then be performed (soil sampling is existing technology and is described in the background technology of this patent). This achieves anti-sway stability support for the four sides of the device frame 1, which improves the anti-sway stability of the soil testing and sampling device when performing soil sampling.

[0029] Additionally, when moving the entire device frame 1 to the location where soil sampling is required, refer to... Figure 2 The four sliding support rods 7 can be slid into the sleeve 51, and then the sliding support rods 7 are positioned by the fixed screw pin 6 and the second locking groove 72. Next, the four sleeves 51 are rotated to a vertical position as a whole, and locked in place by the locking rod 41 and the second locking groove 53. See reference. Figure 3This allows the four sets of sleeves 51 and the sliding support rod 7 to be folded, retracted, positioned, and snapped together. Then, by holding the top lifting frame 12 with one hand, the entire device frame 1 can be easily lifted to the location where soil sampling is required, thus improving the portability and ease of carrying the soil testing and sampling device. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
