Description

Technical Field

[0001] The utility model relates to the technical field of exploration sampling, in particular to a geological exploration sampling device. Background Art

[0002] Geological exploration sampling is an important part of the geological exploration process. Its main purpose is to obtain geological information by collecting representative rock, soil and other samples, and provide a basis for subsequent mineral resource evaluation, engineering design and environmental protection.

[0003] Common geological exploration sampling devices in the prior art generally use a drill rod to drill into the soil, then pull out the drill rod, and then take out the soil inside the drill rod to collect surface or shallow soil samples and understand the soil composition and properties. However, how to quickly remove the soil stuck inside the drill rod is a problem. Generally, the drill rod is removed and then slowly knocked on the drill rod to remove the soil. This operation is more troublesome. Therefore, an improved geological exploration sampling device is needed to address this problem. Utility Model Content

[0004] The purpose of the present invention is to provide a geological exploration sampling device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a geological exploration sampling device, comprising a fixed plate, a shell is fixedly provided at the middle part of the upper end of the fixed plate, a sampling mechanism for drilling sampling is provided at the middle part of the inner side of the shell, the sampling mechanism comprises a rotating rod, a first connecting head, a second connecting head, a sampling drill rod, an electric push rod, and a pushing piston, a rotating rod is movably provided at the middle part of the inner side of the shell through a bearing, a first connecting head is fixedly provided at the lower end of the rotating rod, a second connecting head is provided at the lower end of the first connecting head, a sampling drill rod is fixedly provided at the lower end of the second connecting head, an electric push rod is fixedly provided at the upper end of the shell, and a pushing piston is movably engaged inside the rotating rod.

[0006] Preferably, the movable end of the electric push rod is movably connected to the pushing piston through an annular groove, so that the contraction of the electric push rod can drive the pushing piston to move up and down, and the pushing piston can rotate around the movable end of the electric push rod; the contraction of the electric push rod can drive the pushing piston to move up and down, but since the rotating rod and the sampling drill rod rotate during operation, the pushing piston engaged in the rotating rod or the sampling drill rod will also rotate, so that unnecessary friction loss can be avoided.

[0007] Preferably, the inner side wall of the first connector is provided with a first thread, and the outer surface of the second connector is provided with a second thread. The second connector is movably screwed into the first connector through the second thread and the first thread, so that the first connector and the second connector are fixedly connected by the thread, so that the sampling drill rod can be disassembled at any time when needed, and the rotation direction of the rotating rod during sampling should be the tightening direction of the first thread and the second thread.

[0008] Preferably, a worm gear is fixedly provided on the outer surface of the rotating rod, and a worm is movably provided on one side of the worm gear inside the housing through a bearing. The worm gear and the worm gear are engaged with each other, and the rotation of the worm gear can drive the worm gear to rotate, thereby driving the rotating rod and the sampling drill rod to rotate together.

[0009] Preferably, handles are fixedly provided on both sides of the upper end of the fixed plate, and the handles can be used to conveniently lift the entire device for movement and drilling sampling.

[0010] Preferably, a motor is fixedly provided on the upper end of the fixed plate on one side of the shell, and the output shaft end of the motor is connected to the worm through a coupling, so that the worm can be easily driven to rotate by the motor, thereby driving the worm wheel to rotate through the worm.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model waits until the drill rod is inserted into the target depth and then pulls out the entire device. At this time, there is no need to remove the sampling drill rod and then slowly knock and vibrate the sampling drill rod to take out the soil inside the sampling drill rod. It is only necessary to extend the electric push rod and push the piston downward. In this way, the soil inside the sampling drill rod can be squeezed out by using this activity. In this way, there is no need to remove the drill bit after sampling. The soil layer inside the drill rod can be squeezed out directly by extrusion, which can facilitate continuous sampling work and improve sampling efficiency.

[0013] 2. The utility model can drive the push piston to move up and down through the contraction of the electric push rod. However, since the rotating rod and the sampling drill rod rotate during operation, the push piston engaged in the rotating rod or the sampling drill rod will also rotate. This connection can avoid unnecessary friction loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The movable end of the electric push rod 7 is movably connected to the pushing piston 8 through the annular groove, so that the contraction of the electric push rod 7 can drive the pushing piston 8 to move up and down, and the pushing piston 8 can rotate around the movable end of the electric push rod 7; the contraction of the electric push rod 7 can drive the pushing piston 8 to move up and down, but since the rotating rod 3 and the sampling drill rod 6 rotate during operation, the pushing piston 8 engaged in the rotating rod 3 or the sampling drill rod 6 will also rotate. This connection can avoid unnecessary friction loss;

[0022] The first connector 4 has a first thread 9 formed on its inner side wall, and the second connector 5 has a second thread 10 formed on its outer side surface. The second connector 5 is movably screwed together with the first thread 9 through the second thread 10, so that the first connector 4 and the second connector 5 are fixedly connected by the thread. In this way, the sampling drill rod 6 can be disassembled at any time when needed, and the rotation direction of the rotating rod 3 during sampling should correspond to the tightening direction of the first thread 9 and the second thread 10.

[0023] A worm gear 11 is fixedly provided on the outer surface of the rotating rod 3, and a worm 12 is movably provided on one side of the worm gear 11 inside the housing 2 through a bearing. The worm gear 11 and the worm 12 are engaged with each other, and the rotation of the worm 12 can drive the worm gear 11 to rotate, thereby driving the rotating rod 3 and the sampling drill rod 6 to rotate together;

[0024] The upper end of the fixing plate 1 is fixed with handles 14 on both sides, and the handles 14 can be used to easily lift the entire device for movement and drilling sampling.

[0026] Working principle: When using this device, the worm 12 is driven to rotate by the motor 13, so that the worm gear 11 can drive the rotating rod 3 and the sampling drill rod 6 to rotate. Then the staff rotates the sampling drill rod 6 and presses down the device, so that the sampling drill rod 6 is inserted into the soil, and finally the inside of the drill rod is filled with soil. After the drill rod is inserted to the target depth, the device can be pulled out as a whole. At this time, this device does not need to remove the sampling drill rod 6 and then slowly knock and vibrate the sampling drill rod 6 to take out the soil inside the sampling drill rod 6. It is only necessary to extend the electric push rod 7 and push the piston 8 downward. In this way, this activity can be used to squeeze out the soil inside the sampling drill rod 6. In this way, there is no need to remove the drill bit after sampling. The soil layer inside the drill rod can be directly squeezed out by extrusion, which can facilitate continuous sampling work to improve sampling efficiency.
