Description

Technical Field

[0001] The present application relates to the technical field of soil sampling, and in particular to a soil sampling device. Background Art

[0002] Most of the soil sampling devices currently in use are electric sampling devices, which require a power source and are not suitable for a variety of working environments. In the process of continuous downward pressure sampling by general manual sampling devices, the soil in the sampling device is constantly compressed and condensed into blocks inside the device, especially soil with a high water content, which is hardened inside the device, ultimately making it difficult to collect and load samples after sampling with the current sampling device, and other tools are needed to help remove the samples. At the same time, there is a lack of stabilization devices during sampling, and the stability of the device is difficult to guarantee when sampling downward. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides a soil sampling device, which is designed with a sample pushing structure, and can achieve rapid sample loading after sampling, and the sampling process is stabilized by a base.

[0004] The first aspect of the present application provides a soil sampling device, comprising: a rotating disk, a drill rod, a sample tube, a drill bit and a base. A threaded hole is provided at the top of the sample tube, and the bottom end is connected to the drill bit. The top end of the drill rod passes through the sample tube and is connected to the rotating disk. A push plate is provided at the bottom end to abut against the sample tube. The upper end of the drill rod is threadedly connected to the base.

[0005] Furthermore, the device also includes a portable tool box, and the portable tool box is provided with mounting grooves corresponding to the rotating disk, the drill rod, the drill bit and the base.

[0006] Furthermore, the teeth of the drill bit are of a trapezoidal structure.

[0007] Furthermore, the base is a triangular base, and a limiting sleeve is provided on the base, and the limiting sleeve is sleeved outside the drill rod.

[0008] The technical solution provided by this application may have the following beneficial effects:

[0009] The present application provides a soil sampling device, which uses a rotating disk as a force-applying gripper and does not require the use of other power sources. The force applied during the process is uniform and easy to control, and is suitable for use in special environments such as those without electricity and water sources. During the sampling process, the base always fixes the sampling device to a fixed position, thereby achieving smooth sampling without shaking. After sampling, the soil sample is pushed out of the sample tube by using a push plate through the reverse rotation of the drill rod. Sample loading is convenient and quick, and no other tools are required. The device can quickly achieve sampling and loading, and has good practicality.

[0022] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0023] Figure 1 is a schematic structural diagram of a soil sampling device shown in an embodiment of the present application;

[0024] like Figure 1 The soil sampling device shown comprises: a rotating disk 1, a drill rod 2, a sample tube 4, a drill bit 7 and a base 5. The drill rod 2 is a threaded rod, with the rotating disk 1 installed on the top and a push plate 3 on the bottom. The top surface of the sample tube 4 is provided with a threaded hole matched with the drill rod 2, and a drill bit 7 is connected to the bottom. The drill bit 7 uses a hole opener drill bit, and the teeth of the drill bit 7 are a trapezoidal structure, such as Figure 3 As shown, the drill bit 7 is connected to the sample tube 4 through threads.

[0025] The drill rod 2 is installed from the bottom of the sample tube 4, and the drill rod 2 passes through the threaded hole at the top of the sample tube 4. The length of the push plate 3 is greater than the diameter of the threaded hole so that the push plate 3 is limited in the sample tube 4. After the drill bit 7 is inserted into the top of the drill rod 2, it is rotated upward until the push plate 3 and the top of the sample tube 4 are against each other. Since the length of the push plate 3 is greater than the diameter of the threaded hole, the push plate 3 cannot be pushed out of the threaded hole, thereby realizing the fixed connection between the drill rod 2 and the sample tube 4.

[0026] A base 5 is also installed on the upper end of the drill rod 2. The base 5 is a triangular stable base. The base 5 is used to support the limit device to prevent the device from shaking during sampling. Figure 4As shown, the base 5 includes a limit plate and three support rods connected to the limit plate. The support rods are retractable structures, and the height of the base 5 can be adjusted according to the sampling height. The limit plate is provided with an internal thread hole matching the thread of the drill rod 2. The limit plate is threadedly connected to the drill rod 2 to limit the drill rod 2. In order to further improve the stability, a limit sleeve 6 is also provided on the base 5. The limit sleeve 6 is sleeved outside the drill rod 2, and both ends are fixedly connected to the base 5 to prevent the drill rod 2 from shaking.

[0027] The threads of the rotating disk 1, the drill rod 2, the sample tube 4, the drill bit 7 and the base 5 are all in the same direction, which can meet the requirements of locking all structures when the device rotates clockwise.

[0028] The use process of the device: the sample tube 4 is threadedly connected with the drill bit 7. After rotating clockwise to lock and fix, insert the top of the drill rod 2 into the drill bit 7, rotate the drill rod clockwise upward until the push plate 3 and the bottom of the sample tube 4 are stuck, and install the base 5 and the rotating disk 1 on the upper part of the drill rod 2. The rotating disk 1 is rotated clockwise to drive the sample tube 4 and the drill bit 7 to rotate for sampling. The soil enters the sample tube 4 from the drill bit 7 and solidifies in the sample tube 4. The sampling depth is determined by measuring the downward length of the drill rod 2. When there is no specific requirement for the sampling depth, the sampling is assumed to be completed after the rotating disk 1 and the base 5 are abutted. After the sampling is completed, the drill bit 7 is rotated counterclockwise to separate the drill bit 7 from the sample tube 4. At this time, the drill rod 2 is rotated counterclockwise again, so that the drill rod 2 drives the push plate 3 to move downward, and the soil sample is pushed out of the sample tube by the push plate 3 and loaded in the collection device.

[0029] The device also includes a portable tool box, which is provided with mounting grooves corresponding to the rotating disk 1, the drill rod 2, the drill bit 7 and the base 5. The various parts of the device are respectively loaded into the portable tool box and assembled when used, so that the device is easy to carry.

[0030] The present application provides a soil sampling device, which uses a rotating disk as a force-applying gripper and does not require the use of other power sources. The force applied during the process is uniform and easy to control, and is suitable for use in special environments such as those without electricity and water sources. During the sampling process, the base always fixes the sampling device to a fixed position, thereby achieving smooth sampling without shaking. After sampling, the soil sample is pushed out of the sample tube by using a push plate through the reverse rotation of the drill rod. Sample loading is convenient and quick, and no other tools are required. The device can quickly achieve sampling and loading, and has good practicality.
