Description

Technical Field

[0001] The utility model relates to a soil sampler intubation positioning device. Background Art

[0002] The collection of soil samples is a basic link in the monitoring and evaluation of cultivated land quality. Collecting representative samples is a prerequisite for objectively evaluating the quality of cultivated land. The correct soil sampling method is very important to ensure the accuracy of the test. During the sampling process, the soil sampler is inserted vertically downward into the soil to obtain soil samples of the entire sampling depth. When sampling, it is necessary to ensure that the sampler is in close contact with the soil to avoid mixing or contamination of the soil sample. Therefore, when sampling the soil, hold the T-handle of the soil sampler with both hands, press vertically downward or rotate the T-handle clockwise, and slowly drill the drill bit into the soil. When the sampling depth is reached, remove the drill bit. However, in actual operation, due to the different moisture content of the sampled soil and the large degree of freedom of personnel operation, it is very easy to cause the angle of the drill bit to change when rotating, resulting in the drill bit being skewed, which in turn affects the accuracy of the sampling and causes deviations in the test results. Utility Model Content

[0003] The utility model aims to provide a soil sampler inserting tube positioning device.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A soil sampler cannula positioning device comprises a rotating positioning support assembly, a bottom plate positioning support assembly and a sampling assembly, wherein the rotating positioning support assembly is detachably connected to the bottom plate positioning support assembly, and the rotating positioning support assembly is connected to the sampling assembly;

[0006] The bottom plate positioning support assembly includes a bottom base plate, a sampling head limiting plug-in and three vertical rod plug-in sleeves. The sampling head limiting plug-in sleeve is installed at the center of the bottom base plate, and the three vertical rod plug-in sleeves are distributed above the bottom base plate at 120 degrees.

[0007] The soil sampler cannula positioning device, the rotating positioning support assembly includes a vertical pole, a circular support frame, an internally threaded sleeve, a rotating rod and a bearing sleeve. The bottom of the circular support frame is vertically connected to the vertical pole, the center of the circular support frame is a circular hole structure, and the outer ring surface of the bearing sleeve is fixed at the circular hole structure, the inner ring surface of the bearing sleeve is fixedly connected to the internally threaded sleeve, and the outer cylinder arm of the internally threaded sleeve is connected to the rotating rod.

[0008] The soil sampler inserting tube positioning device has the bottom of the vertical pole inserted into the vertical pole inserting sleeve on the positioning support assembly.

[0009] The soil sampler intubation positioning device, the sampling assembly comprises a sampling head, a threaded push rod and a limit plate, the bottom of the threaded push rod is connected to the sampling head, and the top of the threaded push rod is connected to the limit plate.

[0010] The soil sampler intubation positioning device is characterized in that the threaded push rod on the sampling component is screwed into the internal threaded sleeve on the rotating positioning support component.

[0011] The soil sampler insert tube positioning device, the diameter of the sampling head on the sampling assembly is smaller than the inner tube diameter of the sampling head limiting insert tube, so that the sampling head can be inserted into the sampling head limiting insert tube.

[0012] The beneficial effects achieved by the utility model are:

[0013] 1. The utility model is provided with a bottom plate positioning support assembly and a rotating positioning support assembly. When sampling soil, the sampling head is inserted into the sampling head limiting plug-in tube, and the bottom base plate is placed on the soil ground. The bottom base plate and the sampling head limiting plug-in tube are in a vertical structure. Therefore, when the sampling head is inserted into the soil for sampling, the sampling head limiting plug-in tube on the bottom plate positioning support assembly can limit the sampling head, thereby ensuring the accuracy of soil sampling.

[0014] 2. The utility model installs a threaded push rod on the sampling head, and the threaded push rod cooperates with the rotating positioning support assembly. When the sampling head is sent into the soil, it is only necessary to rotate the rotating rod, and the rotating rod drives the internal threaded sleeve to rotate. When the internal threaded sleeve rotates, the threaded push rod on the sampling assembly moves vertically downward, thereby completing the soil sampling of the sampling head.

[0015] 3. The utility model is easy to operate. When sampling soil, the sampling head can always be vertical to the soil surface, avoiding the skew of the sampling head during operation, which affects the accuracy of sampling. At the same time, the sampling head is sent into the soil by rotating the rotating rod, which saves time and effort during the operation, avoiding the need for the original sampler to press down and rotate the handle to complete the soil sampling.

[0028] The bottom plate positioning support assembly includes a bottom substrate 2-1, a sampling head limiting plug-in 2-2 and three vertical pole plug-in sleeves 2-3. The sampling head limiting plug-in is installed at the center of the upper circle of the bottom substrate, and the three vertical pole plug-in sleeves are distributed above the bottom substrate at 120 degrees. The bottom substrate is a circular metal plate structure, and the sampling head limiting plug-in is fixed at the center of the circle of the bottom substrate by welding. The sampling head limiting plug-in is a through structure, and the sampling head on the sampling assembly can be inserted into the sampling head limiting plug-in; the three vertical pole plug-in sleeves are evenly fixed on the bottom substrate by welding.

[0029] Embodiment 2:

[0030] A soil sampler cannula positioning device, wherein the rotating positioning support assembly comprises a vertical pole 1-1, a circular support frame 1-2, an internally threaded sleeve 1-3, a rotating rod 1-4 and a bearing sleeve 1-5, wherein the bottom of the circular support frame is vertically connected to the vertical pole, the center of the circular support frame is a circular hole structure, and the outer annular surface of the bearing sleeve is fixed at the circular hole structure, the inner annular surface of the bearing sleeve is fixedly connected to the internally threaded sleeve, and the outer cylinder arm of the internally threaded sleeve is connected to the rotating rod.

[0031] The soil sampler insert positioning device has the bottom of the vertical pole inserted into the vertical pole sleeve on the positioning support assembly. The vertical pole is a solid metal rod structure, and the top of the vertical pole is vertically fixed below the circular support frame by welding. The diameter of the vertical pole is slightly smaller than the inner diameter of the vertical pole sleeve, so that the vertical pole can be inserted into the vertical pole sleeve. The outer ring surface of the bearing sleeve is fixed to the circular hole on the circular support frame by welding, so that the circular support frame and the bearing sleeve are an integrated structure; the inner ring surface of the bearing sleeve is connected to the internal thread sleeve by welding, so that the internal thread sleeve can rotate in the inner ring surface of the middle bearing sleeve.
