Description

Technical Field

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

[0002] The soil pollution sampling device is a sampling device for detecting polluted soil. The commonly used portable soil pollution sampling device is usually a cylinder with a toothed bottom and a main rod above the cylinder. At this time, the main rod is held and the cylinder is inserted into the bottom. At this time, the main rod is rotated, and the soil will remain inside the cylinder. The soil sampling process can be completed by pulling the cylinder out of the ground.

[0003] When sampling soil at a specific depth, the soil is accumulated in the cylinder, so that the cylinder can only dive to a limited depth, resulting in the inability to reach the sampling depth. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a portable soil pollution sampling device. When the sampling tube samples soil at a specific depth, the soil cannot accumulate in the sampling tube during the diving process, which facilitates the sampling tube to dive to a specific depth for soil sampling.

[0005] The purpose of this disclosure can be achieved through the following technical solutions:

[0006] Portable soil contamination sampling device, including:

[0007] A first sleeve, wherein the upper and lower ends of the first sleeve are rotatably connected to the frame, a turbine is fixedly connected to the top of the first sleeve, the turbine is meshed with the worm, and both ends of the worm are rotatably connected to the frame;

[0008] The first sleeve is provided with a second sleeve sliding along its length direction, the second sleeve is provided with a third sleeve sliding along its length direction, the third sleeve is fixedly connected with a screw extending upward and passing through the first sleeve, and the screw is threadedly connected to the frame;

[0009] The upper end is an open sampling tube, the interior of which is detachably connected to a connecting shaft, a spiral blade is fixedly connected to the circumference of the connecting shaft, the upper end of the connecting shaft is detachably connected to the lower end of the third sleeve, a symmetrical notch is opened at the bottom of the sampling tube, and an oblique knife is fixedly connected to one side of the notch.

[0010] The above technical solution, its principle and technical effect:

[0011] The frame is held by hand to hold the sampling tube against the ground, and the worm is driven to drive the turbine to rotate. The turbine drives the first sleeve to rotate, and the sampling tube follows the first sleeve to rotate through the transmission of the second sleeve, the third sleeve, and the connecting shaft. While the sampling tube rotates, the oblique knife shovels the soil into the sampling tube through the slot. At the same time, the screw also follows the rotation of the third sleeve, and moves downward while the screw rotates, thereby causing the second sleeve and the third sleeve to move downward, so that the sampling tube rotates and moves downward at the same time. During the downward movement of the sampling tube, due to excessive soil entering the sampling tube, the soil shoveled in later will push the soil inside the sampling tube to move upward through the spiral blades and then be discharged from the sampling tube until the sampling tube reaches a predetermined depth. At this time, the worm is rotated in the opposite direction to cause the sampling tube to be screwed out upward. At this time, the soil in the sampling tube is the soil sample that needs to be obtained at a specific depth. The soil sample can be taken out by simply disassembling the connecting shaft and the sampling tube.

[0012] Furthermore, the frame includes a first connecting ring and a second connecting ring rotatably connected to the upper and lower ends of the first sleeve, a first fixing rod and a second fixing rod are fixedly connected to the first connecting ring and the second connecting ring on both sides, a third fixing rod is fixedly connected between the first fixing rod and the second fixing rod, a fourth fixing rod is fixedly connected between the top ends of the two third fixing rods, a screw rod passes through the fourth fixing rod and is threadedly connected to the fourth fixing rod, an ear plate is fixedly connected to the side surface on the same side of the two third fixing rods, and both ends of the worm are rotatably connected to the ear plate.

[0013] Furthermore, one end of the worm is fixedly connected to the output end of the motor, and the motor is fixedly connected to the ear plate.

[0014] Furthermore, a first slide groove is opened on the circumferential side of the first sleeve along its length direction, a first protrusion is fixedly connected to the circumferential side of the upper end of the second sleeve, the first protrusion is slidably connected in the first slide groove, a second slide groove is opened on the circumferential side of the second sleeve along its length direction, a second protrusion is fixedly connected to the circumferential side of the upper end of the third sleeve, and the second protrusion is slidably connected in the second slide groove.

[0015] Furthermore, the lower end of the third sleeve is fixedly connected to an internally threaded sleeve, and the upper end of the connecting shaft is fixedly connected to a first threaded column threadedly connected to the internally threaded sleeve.

[0016] Furthermore, a head is fixedly connected between the first threaded column and the connecting shaft.

[0017] Furthermore, a second threaded column is fixedly connected to the lower end of the connecting shaft, and the second threaded column passes through the bottom of the sampling tube and is threadedly connected to the nut.

[0018] Furthermore, a positioning groove is provided on the inner side wall of the sampling tube, and a positioning strip for inserting into the positioning groove is fixedly connected to the side of the spiral blade.

[0019] Furthermore, a thread groove is provided on the circumference of the sampling tube.

[0020] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0021] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0022] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0023] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0024] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0025] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0026] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0027] Beneficial effects of the present disclosure:

[0028] When the sampling tube is sampling soil at a specific depth, the soil cannot accumulate in the sampling tube during the diving process of the sampling tube, which facilitates the sampling tube to dive to the specific depth for soil sampling. BRIEF DESCRIPTION OF THE DRAWINGS
