Description

Technical Field

[0001] The utility model belongs to the technical field of geological exploration equipment, and particularly relates to a portable soil sampler which is convenient for drilling. Background Art

[0002] In land quality surveys, soil pollution site surveys, and a series of routine geochemical prospecting, traditional Luoyang shovels are needed to collect deep soil samples. Traditional Luoyang shovels are easy to manufacture and convenient to carry, and are widely used in geological exploration. The traditional Luoyang shovel can be combined with a lengthened rod and a semi-cylindrical iron shovel. When in use, the operator needs to exert force with the waist and horse in one, rotate the long rod when shoveling, hold the long rod tightly with both hands, drive the semi-circular iron shovel to shovel vertically downward, and use the iron shovel to bring out the soil, so as to obtain deep soil samples.

[0003] In actual operation, the traditional Luoyang shovel is held by hand with a long rod, and is vertically forced downward at a certain rotation speed. The soil sample is brought out through the shoveling of the shovel head. The process is very laborious and inefficient. In case of hard and dense soil layers, it is often more difficult to exert force, and there are certain requirements for the proficiency of the user. It is not suitable for everyone to use.

[0004] Therefore, it is necessary for us to design a portable soil sampler that is convenient for drilling to solve these problems. Content of the Utility Model

[0005] The problem to be solved by the utility model is to provide a portable soil sampler that is convenient for drilling. The gear combination is used to conduct and exert force. The three-legged support frame can assist the sampling cylinder to keep perpendicular to the ground, so that the sampling cylinder is not easy to deviate during drilling. The downward pressure is maintained by the grip, and the gear combination drives the sampling cylinder to rotate and drill through the screw rod.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A portable soil sampler that is convenient for drilling, including a power part and a support part. The output end of the power part is fixedly provided with a drilling rod, and the free end of the drilling rod is fixedly provided with a sampling cylinder. The support part is sleeved on the drilling rod; the power part includes a connecting frame, a stabilizing frame, a driving gear, a movable gear and a hand crank. The stabilizing frame is fixedly arranged inside the connecting frame. The movable gear is rotatably arranged between the stabilizing frame and the connecting frame. The drilling rod is connected to the movable gear. The driving gear is rotatably arranged on the stabilizing frame and meshes with the movable gear. The hand crank is fixedly arranged on the driving gear; the support part includes a positioning ring, a support rod and a limiting rod. One end of the support rod is hinged to the positioning ring. The free end of the support rod is fixedly provided with a stabilizing anchor rod. A pedal is also fixedly arranged on the support rod. The limiting rod slidably penetrates through the positioning ring and one end is connected to the connecting frame.

[0008] Preferably, a connecting bearing is further provided on the connecting frame. The number of the connecting bearings and the movable gears is at least two. The outer rings of the two connecting bearings are fixedly connected to the connecting frame and symmetrically distributed along the stabilizing frame. The two movable gears are connected to the connecting frame through the connecting bearings. A connecting pipe is fixedly provided on one of the movable gears, and the free end of the connecting pipe extends out from the inner ring of the connecting bearing.

[0009] With such a setting, the resistance can be reduced and the operation is facilitated.

[0010] Preferably, the sampling cylinder is of a cylindrical structure. A fixing frame is provided at one end, a connecting seat is provided on the fixing frame, and drilling teeth are provided at the other end. The free end of the drilling rod is fixedly connected to the closed end of the sampling cylinder.

[0011] With such a setting, it is convenient to drill into the soil layer.

[0012] Preferably, a handle is further fixedly provided on the connecting frame.

[0013] With such a setting, it is convenient to fix the device during drilling.

[0014] Preferably, the number of the support rods and the limiting rods is at least three, and the three support rods and the three limiting rods are evenly distributed circumferentially around the positioning ring.

[0015] With such a setting, the three evenly distributed support rods can provide stable support.

[0016] Preferably, threads are respectively provided on the outer wall of the drilling rod and the inner wall of the positioning ring, and the positioning ring and the drilling rod are matched with each other.

[0017] With such a setting, through the mutual cooperation of the threads, the drilling rod can push the sampling cylinder into the soil layer during drilling.

[0018] Preferably, the fixing frame is in a "cross" shape, and the connecting seat is arranged at the intersection of the fixing frame.

[0019] With such a setting, the force can be more balanced, and the air in the sampling cylinder can be discharged when the sampling cylinder drills into the soil layer, reducing the resistance.

[0020] Preferably, the limiting rod is fixedly connected to the outer ring of the connecting bearing.

[0021] With such a setting, by using the connection between the limiting rod and the positioning ring, it is possible to prevent the power part from rotating due to the reaction force during drilling.

[0022] Preferably, one end of the drilling rod is inserted into the connecting pipe and fixedly connected to the connecting pipe through a pin, and the other end is connected to the connecting seat through a thread.

[0023] With such a setting, it can be ensured that the soil sampling cylinder can be driven to rotate when the power unit outputs in forward or reverse rotation.

[0024] The advantages and positive effects of the present utility model are:

[0025] Compared with the traditional Luoyang shovel, the beneficial effects of the present utility model are as follows: Through the gear combination, not only can the effective transmission of power be realized, and the sampling cylinder can be pushed into the ground by the mutual cooperation of the threads on the drilling rod and the positioning ring. The drilling tooth structure of the sampling cylinder can easily break through the soil layer, and the downward drilling force is greater. The three-legged support frame plays an auxiliary stabilizing role, and it can ensure that the sampling cylinder drills vertically to the ground during operation. Compared with the sampling device in the form of the traditional Luoyang shovel, the operation method of the hand crank + gear combination drive is more time-saving and labor-saving, greatly reducing the requirements for operators. The drilling rods can also be connected to each other through pins, increasing the detection depth and improving the operation effect of the sampler on the soil layer. Description of the Drawings

[0033] The following further describes the present utility model with reference to the drawings:

[0034] Embodiment 1: As Figure 1 and Figure 2 shown, a portable soil sampler facilitating drilling includes a power part and a support part. A drilling rod 8 is fixedly arranged at the output end of the power part, and a sampling cylinder 11 is fixedly arranged at the free end of the drilling rod 8. The support part is sleeved on the drilling rod 8. The power part includes a connecting frame 2, a stabilizing frame 7, a driving gear 4, a movable gear 3, and a hand crank 5. The stabilizing frame 7 is fixedly arranged inside the connecting frame 2. The movable gear 3 is rotatably arranged between the stabilizing frame 7 and the connecting frame 2. The drilling rod 8 is connected to the movable gear 3. The driving gear 4 is rotatably arranged on the stabilizing frame 7 and meshes with the movable gear 3. The hand crank 5 is fixedly arranged on the driving gear 4. The support part includes a positioning ring 9, a support rod 10, and a limiting rod 19. One end of the support rod 10 is hinged to the positioning ring 9. A stabilizing anchor rod 13 is fixedly arranged at the free end of the support rod 10. A pedal 12 is also fixedly arranged on the support rod 10. The limiting rod 19 slidably penetrates through the positioning ring 9 and one end thereof is connected to the connecting frame 2.

[0035] Specifically, a connecting bearing 14 is further provided on the connecting frame 2. The number of the connecting bearings 14 and the movable gears 3 is at least two. The outer rings of the two connecting bearings 14 are fixedly connected to the connecting frame 2 and symmetrically distributed along the stabilizing frame 7. The two movable gears 3 are connected to the connecting frame 2 through the connecting bearings 14. A connecting pipe 18 is fixedly provided on one of the movable gears 3. The free end of the connecting pipe 18 extends out from the inner ring of the connecting bearing 14. Such a setting can reduce resistance and facilitate operation.

[0036] Specifically, the sampling cylinder 11 is of a cylindrical structure. A fixing frame 17 is provided at one end. A connecting seat 16 is provided on the fixing frame 17. Drilling teeth 20 are provided at the other end. The free end of the drilling rod 8 is fixedly connected to the closed end of the sampling cylinder 11. Such a setting facilitates drilling into the soil layer.

[0037] Specifically, a grip 1 is further fixedly provided on the connecting frame 2. Such a setting facilitates fixing the device during drilling.

[0038] Specifically, the number of the support rods 10 and the limiting rods 19 is at least three, and the three support rods 10 and the three limiting rods 19 are evenly distributed circumferentially around the positioning ring 9. Such a setting can provide stable support through the three evenly distributed support rods 10.

[0039] Specifically, threads are respectively provided on the outer wall of the drilling rod 8 and the inner wall of the positioning ring 9, and the positioning ring 9 and the drilling rod 8 are matched with each other. Such a setting can enable the drilling rod 8 to push the sampling cylinder 11 into the soil layer during drilling through the mutual cooperation of the threads.

[0040] Specifically, the fixing frame 17 is in a "cross" shape, and the connecting seat 16 is arranged at the intersection of the fixing frame 17. Such a setting can make the force more balanced and can also discharge the air in the sampling cylinder 11 when the sampling cylinder 11 drills into the soil layer, reducing resistance.

[0041] Specifically, the limiting rod 19 is fixedly connected to the outer ring of the connecting bearing 14. Such a setting can prevent the power part from rotating due to the reaction force during drilling by using the connection between the limiting rod 19 and the positioning ring 9.

[0042] Specifically, one end of the drilling rod 8 is inserted into the connecting pipe 18 and then fixedly connected to the connecting pipe 18 through a pin 6, and the other end is connected to the connecting seat 16 through a thread. Such a setting can ensure that the power part can drive the soil sampling cylinder 11 to rotate when rotating forward or backward.

[0043] In this embodiment, the grip 1 is a cylindrical-like structure with a curvature suitable for hand grasping on the side wall. It can be understood that the bending curvature on the grip 1 can make the operator's hand more comfortable to hold.

[0044] Working process of this embodiment: When in use, first expand the three support rods on the positioning ring 9, then step on the pedal 12 to step the stabilizing anchor 13 into the ground, then screw the drilling rod 8 onto the positioning ring 9 through threads, then put the connecting seat 16 on the sampling cylinder 11 over one end of the drilling rod 8, and connect the connecting seat 16 and the drilling rod 8 through the pin 6. Insert the other end of the drilling rod 8 into the connecting pipe 18 and also connect it through the pin 6 to achieve the assembly connection of each component. Then, an operator holds the grip 1 with one hand and starts to rotate the hand crank 5 with the other hand. After the hand crank 5 is rotated, it will drive the driving gear 4 to rotate. The driving gear 4 will drive the meshing movable gear 3 to rotate. The movable gear 3 will drive the drilling rod 8 to rotate. At the same time, the sampling cylinder 11 will also rotate driven by the drilling rod 8. The drilling rod 8 will move downward through the threads on the positioning ring 9.

[0045] When the drilling rod 8 rotates, it will drive the soil sampling cylinder 11 to rotate. When the soil sampling cylinder 11 contacts the ground under the push of the drilling rod 8, the drilling teeth 20 on the soil sampling cylinder 11 will break the ground soil quality, enabling the soil sampling cylinder 11 to drill into the ground. And while the soil sampling cylinder 11 drills into the ground, the staff can observe the situation inside the soil sampling cylinder 11 through the gap between the fixing frames to ensure that the soil sampling amount can meet the requirements.

[0046] Among them, the drilling rods 8 can also be connected and fixed through the pin 6. Therefore, when the sampling depth is relatively deep, multiple drilling rods 8 can be connected to achieve sampling at a deeper part of the underground.

[0047] The above has described an embodiment of the present utility model in detail, but the content is only the preferred embodiment of the present utility model and cannot be considered as used to limit the implementation scope of the present utility model. All equal changes and improvements made according to the application scope of the present utility model should still fall within the patent coverage scope of the present utility model.
