Soil layer drilling sampling device

Abstract

The utility model discloses a soil layer drilling and sampling device, comprising a soil sampling drill, a drill rod and a soil sampling tube. The bottom of the soil sampling drill is clamped with the drill rod installed on the top of the soil sampling tube, and also comprises a convex block and a pipe lifting mechanism. The rod body of the drill rod is symmetrically fixed with convex blocks, and the surface of the convex blocks penetrates through the set holes. The convex blocks and the matching pipe lifting mechanism are arranged at the drill rod of the soil sampling drill. The soil sampling drill can normally press the drill rod and the soil sampling tube to press them down into the soil. When the soil sampling tube enters the soil layer and needs to be pulled out, the pipe lifting mechanism can be clamped at the position of the drill rod and the convex block exposed outside the soil layer for installation. Then, with the help of the hydraulic lifting force of the jack, the drill rod and the soil sampling tube are pushed up and pulled out of the soil layer. Compared with workers using a puller to pull up the soil sampling tube, the pipe lifting mechanism of the utility model pulls up the soil sampling tube with less force, which is convenient for workers to pull out the tube after soil layer drilling and sampling.

Description

Technical Field

[0001] The utility model relates to the technical field of soil layer drilling and sampling, in particular to a soil layer drilling and sampling device. Background Art

[0002] Soil sampling is the basic work in the fields of soil analysis, research and geological exploration. Soil composition and soil property parameters are measured and determined by sampling soil at different depths, so as to evaluate and study the degree of soil pollution. When sampling soil, workers usually use a soil-drilling drill as a sampling device. With the help of the sampling device that drills into the soil layer, the soil can be brought up from the soil layer for sampling.

[0003] When the soil sampling device of the prior art is sampling the soil layer, the soil drilling machine will be started to generate impact force, so that the soil sampling tube connected to the drill rod below the soil drilling machine enters the soil layer to drill and extract soil. After the soil sampling tube enters the soil layer to take samples, workers usually need to remove the soil drilling machine from above the drill rod, and then use the puller to clamp the clamp outside the drill rod, and then use the puller to hook the chain of the clamp to pull up the drill rod and the soil sampling tube for sampling. The workers need to consume more physical strength when operating the puller, which makes it difficult to pull out the soil sampling tube of the soil drilling machine for soil unloading after entering the soil, thereby affecting the sampling and soil unloading efficiency of the soil sampling tube. For this reason, we propose a soil drilling sampling device. Utility Model Content

[0004] The main purpose of the utility model is to provide a soil drilling and sampling device, in which a protrusion and a matching lifting pipe mechanism are arranged at the drill rod of the soil drilling rig, the soil drilling rig can normally press the drill rod and the soil sampling pipe to push them down into the soil, and when the soil sampling pipe enters the soil layer and needs to be pulled out, the lifting pipe mechanism can be clamped on the drill rod and the protrusion position exposed outside the soil layer for installation, and then with the help of the hydraulic lifting force of the jack, the drill rod and the soil sampling pipe are pushed up and pulled out of the soil layer. Compared with workers using a puller to pull up the soil sampling pipe, the lifting pipe mechanism of the utility model pulls up the soil sampling pipe with less force, which is convenient for workers to perform the pipe pulling operation after soil drilling and sampling, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The top of the U-shaped seat is welded with a fixed rod inserted into the fixed hole, and the top plate is welded with a connecting plate outside the arc seat plate of the U-shaped seat, a cartridge is welded below the plate body of the top plate, and a telescopic rod body of the jack is clamped in the cartridge, a U-shaped leg clamped on the outside of the seat body on one side of the jack is welded, and a pedal is welded outside the seat body on the other side of the jack away from the U-shaped leg.

[0007] Furthermore, a pressurizing rod is inserted into the pressurizing driving position of the jack;

[0008] By adopting the above technical solution, the pressurized driving position of the jack can be manually pressurized and driven by inserting a pressurized rod.

[0009] Furthermore, the plate body of the connecting plate is inclined outward from the seat body of the U-shaped seat, and a rib plate is protruded on the surface of the plate body of the connecting plate;

[0010] By adopting the above technical solution, the U-shaped seat can obtain better support force at the top plate with the help of the inclined plate body of the connecting plate, and the rib plate protrusions at the connecting plate enhance the strength of the plate body itself.

[0011] Furthermore, a U-shaped support groove larger than the soil sampling pipe is provided in the plate body of the U-shaped support foot;

[0012] By adopting the above technical solution, the plate body of the U-shaped support foot can be clamped outside the soil taking pipe with the U-shaped support groove to contact the ground.

[0013] Furthermore, the width of the seat groove of the U-shaped seat is the same as the diameter of the drill rod;

[0014] By adopting the above technical solution, the U-shaped seat can be adapted to be clamped outside the drill pipe for installation.

[0015] Furthermore, a vertical strip opening is vertically opened on the wall of the cartridge;

[0016] By adopting the above technical solution, after soil enters the barrel, it can be manually cleaned out from the vertical strip opening using branches or other rods.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model provides a protrusion and a matching lifting pipe mechanism at the drill rod of the soil drilling rig, so that the soil drilling rig can normally press the drill rod and the soil sampling pipe downward into the soil. When the soil sampling pipe enters the soil layer and needs to be pulled out, the lifting pipe mechanism can be clamped at the position of the drill rod and the protrusion exposed outside the soil layer for installation. Then, with the help of the hydraulic lifting force of the jack, the drill rod and the soil sampling pipe are pushed up and pulled out of the soil layer. Compared with workers using a puller to pull up the soil sampling pipe, the lifting pipe mechanism of the utility model pulls up the soil sampling pipe with less force, which is convenient for workers to perform the pipe pulling operation after drilling into the soil layer and taking samples.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The drill rod 2 below the protrusion 4 is symmetrically fixed with a set hole 5 on the surface of the protrusion 4. A U-shaped seat 7 is clamped, and side blocks 8 are symmetrically welded outside the seat body of the U-shaped seat 7, a fixed rod 9 inserted into the fixed hole 5 is welded to the top of the side block 8 and the U-shaped seat 7, and a top plate 11 is welded to the outside of the arc-shaped seat plate of the U-shaped seat 7 with a connecting plate 10, a clamping cylinder 12 is welded below the plate body of the top plate 11, and a telescopic rod body of a jack 13 is clamped in the clamping cylinder 12, a U-shaped support leg 14 clamped outside the soil sampling pipe 3 is welded to the outside of the seat body on one side of the jack 13, and a pedal 15 is welded to the outside of the seat body on the other side of the jack 13 away from the U-shaped support leg 14.

[0025] Wherein, a pressurizing rod 16 is inserted into the pressurizing driving position of the jack 13;

[0026] By adopting the above technical solution, the pressurized driving position of the jack 13 can be manually pressurized and driven by inserting the pressurized rod 16 .

[0027] The plate body of the connecting plate 10 is inclined outward from the seat body of the U-shaped seat 7, and a rib plate 17 is protruded from the surface of the plate body of the connecting plate 10;

[0028] By adopting the above technical solution, the U-shaped seat 7 can obtain better support force at the top plate 11 with the help of the inclined plate body of the connecting plate 10, and the rib plate 17 protrudes at the connecting plate 10 to enhance the strength of its own plate body.

[0029] Wherein, a U-shaped support groove larger than the soil sampling pipe 3 is provided in the plate body of the U-shaped support foot 14;

[0030] By adopting the above technical solution, the plate body of the U-shaped support leg 14 can be clamped outside the soil taking pipe 3 to contact the ground through the U-shaped support groove.

[0031] The width of the seat groove of the U-shaped seat 7 is the same as the diameter of the rod body of the drill rod 2;

[0032] By adopting the above technical solution, the U-shaped seat 7 can be adapted to be clamped outside the drill rod 2 for clamping.

[0033] The cartridge 12 has a vertical opening on its wall.

[0034] By adopting the above technical solution, after the soil enters the cartridge 12, it can be manually cleaned out from the vertical strip opening using a branch or other rod.

[0035] It should be noted that the utility model is a soil layer drilling sampling device. After a protrusion 4 is set at the drill rod 2 of the soil sampling drill 1, the drill rod 2 can be normally inserted into the soil sampling drill 1 and pinned and connected after the drill rod 2 is screwed on the soil sampling tube 3. Then the soil sampling drill 1 can be started by a worker to generate an impact force, so that the drill rod 2 presses the soil sampling tube 3 to drill into the soil layer under the action of the impact force to perform soil sampling, and the rod body of the drill rod 2 with the protrusion 4 is exposed from the soil layer at a convenient pulling height. When the soil sampling tube 3 enters the soil layer and needs to be pulled out, the worker pulls the soil sampling tube 3 out of the soil layer. The drilling rig 1 is removed from the top of the drill pipe 2 according to its own operating experience, and then the lifting tube mechanism 6 is taken out, so that the telescopic rod body of the jack 13 head of the lifting tube mechanism 6 is inserted into the cartridge 12, and then the top plate 11 above the cartridge 12 is moved toward the drill pipe 2, and then the U-shaped seat 7 connected by the connecting plate 10 of the top plate 11 can cooperate with the side block 8 to contact the protrusion 4 upward from the drill pipe 2, and then the protrusion 4 and the fixed rod 9 at the top of the U-shaped seat 7 are inserted into the fixed hole 5 of the protrusion 4 for connection, and then the U-shaped support leg 14 outside the jack 13 is stuck in the land above the soil pipe 3, and the U-shaped support leg The foot 14 is pressed on the ground outside the hole produced by soil excavation, and the pedal 15 on the other side of the jack 13 can touch the ground. At this time, the pressurized driving position of the jack 13 can be manually pressurized and driven by inserting the pressurized rod 16. Driven by the upward force of the jack 13, the block welded by the top plate 11, the connecting plate 10 and the U-shaped seat 7 rises, so that the U-shaped seat 7 rises with the drill rod 2 on the protrusion 4, thereby bringing out the soil excavation pipe 3 in the soil layer. When the soil excavation pipe 3 leaves the soil layer and is easy to be pulled out, the worker can release the pressure of the jack 13 according to his own operating experience, thereby The drill rod 2 loses its supporting force, and then the drill rod 2 is held and lifted up, so that the protrusion 4 leaves the U-shaped seat 7, and the soil sampling tube 3 is also pulled out of the soil layer. At this time, the lifting mechanism 6 can be taken away and carried by the workers, and the tube body of the soil sampling tube 3 can be rotated apart from the drill rod 2, and the cylinders at both ends of the soil sampling tube 3 are opened to pour out the soil sampled from the soil layer, which is convenient for the mechanical force lifting and pulling out of the soil sampling tube 3 when sampling at the soil layer. The length of the protruding part after the protrusion 4 is welded to the drill rod 2 needs to be smaller than the tube body diameter of the soil sampling tube 3 to avoid excessive contact between the protrusion 4 and the soil layer at the drill rod 2.

[0036] It should be noted that the utility model is a soil drilling sampling device, and the components in the utility model are all components known to technical personnel in the field, and their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods.
