Description

Technical Field

[0001] The invention relates to the technical field of soil sampling equipment, and in particular to a horizontal sampling soil drilling rig. Background Art

[0002] Soil sampling refers to the method of collecting soil samples, including the layout and sampling technology of the samples. There are many types of soil sampling drills, which are divided into manual operation and mechanical operation. The mechanical operation drill is driven by a motor to make the drill body enter the soil to a certain depth, and then lift the soil column, lay it flat for observation, and cut and sample as needed. The diameter of the soil column can be controlled by the drill body of different diameters, such as 5 cm, 10 cm or thicker. The mechanical drill is efficient and can save manpower;

[0003] In the prior art, soil sampling still needs horizontal sampling. For example, when soil sampling is performed on some slope structures with loose soil and complex terrain, it is necessary to sample in the horizontal direction, analyze the changes and structural composition of the soil at different depths in the horizontal direction, and understand the reasons for the collapse and landslide of the soil layer. In this case, in order to obtain the reliability of the data, it is usually necessary to perform multiple sampling at various positions and directions of the slope. At this time, the sampler of the soil sampling drill needs to repeat the drilling and sampling. If there are many soil samples from the last sampling left in the sampler, the later analysis data is prone to large errors. In order to drill into the soil layer, the diameter of the drill bit of the sampler is usually not too large, so the soil sample remaining in the sampler is difficult to completely clean, which easily leads to errors in the sampling and analysis data.

[0004] For example, a soil sampling device capable of cleaning a drill bit with publication number CN218156931U includes a box body, a mounting plate, a power supply, a lifting device, and a sampling device. The mounting plate is arranged inside the box body, the power supply is arranged on the left side of the top of the mounting plate, the lifting device and the sampling device are arranged below the mounting plate, and also includes a drill bit cleaning device. The cleaning device includes a shell cover, a base, a cylinder, a scraper, a scraper blade, and a motor. The base is arranged on the right side of the top of the mounting plate, the interior of which is hollow and the upper end is open. The cylinder is vertically arranged in the base, and its piston rod faces upward. The motor is arranged on the piston rod of the cylinder. The output end of the motor faces upward, and a through hole is provided in the middle of the scraper. The scraper is mounted on the motor through the through hole and can move up and down with the motor. The scraper is arranged on the output shaft of the motor, above the scraper, and rotates under the drive of the motor. The shell cover is arranged on the base, and its upper end is open, which can automatically clean the inner wall of the drill bit, saving cost, time and labor, and having high work efficiency. However, when cleaning the drill bit, this device needs to manually place the drill bit into the drill bit cleaning device, and wait for the drill bit cleaning device to clean the drill bit before manually installing the drill bit. It relies too much on manual labor, which affects the efficiency of soil sampling. Summary of the invention

[0005] The present invention provides a horizontal soil sampling drill, which solves the problem that the sampling machine in the related art relies too much on manual labor when cleaning the drill bit, thus affecting the soil sampling efficiency.

[0006] The technical solution of the present invention is as follows:

[0009] Furthermore, the driving mechanism includes a support frame 1, a mounting tube and a hydraulic cylinder, the support frame 1 is fixedly connected to the base, the mounting tube is set to a square shape, the mounting tube is slidably connected to the support frame 1, the mounting tube is threadedly connected to the screw rod, and the hydraulic cylinder is fixedly connected in the mounting tube.

[0010] Furthermore, the drilling mechanism includes a sliding rod, a sampling tube and a sampling drill bit. The sliding rod is located in the mounting tube, one end of the sliding rod is fixedly connected to the hydraulic cylinder, the sampling tube is slidably connected to the sliding rod, the sampling drill bit is fixedly connected to the sampling tube, and a serrated cutting head is provided at the front end of the sampling drill bit.

[0011] Preferably, the sampler includes a second support frame, a soil discharge hole and a damping ring. The second support frame is fixedly connected to the first support frame. There are multiple soil discharge holes, and the multiple soil discharge holes are opened on one end of the sampling tube away from the sampling drill bit. The damping ring is rotatably mounted on the soil discharge holes of the sampling tube, and the damping ring is provided with through holes that are adapted to the soil discharge holes.

[0012] On the basis of the above scheme, preferably, the cleaning and drying mechanism includes a water tank, a water pump, a reversing valve, a water pipe, a fan and a spiral hose, the water tank is fixedly connected to the base, the water pump is fixedly connected to the water tank, the output end of the water pump is divided into two, two reversing valves are provided, and the two reversing valves are fixedly connected to the side wall of the sampling tube, four water pipes are provided, and the four water pipes are respectively connected to the output end of the water pump and the two reversing valves, the fan is fixedly connected to the sampling tube, and the output end of the fan is connected to the reversing valve, and two spiral hoses are provided, and each of the spiral hoses is respectively fixedly connected to the two water pipes located on the same side.

[0013] On the basis of the above solution, more preferably, the front section and the rear end of the sampling tube are detachably connected to take out the soil sample collected by the sampling tube.

[0014] The working principle and beneficial effects of the present invention are:

[0015] 1. In the present invention, the sampling position of the sampler can be adjusted in the vertical direction through the operation of the positioning mechanism. When sampling in terrains such as soil slopes with complex terrain, the sampler has wider applicability and a wider sampling range. The data obtained from the sample analysis in the later stage is more reliable. The positioning mechanism can also provide better stability for the device and reduce the difficulty of sampling operations.

[0016] 2. In the present invention, through the cooperation of the driving mechanism and the drilling mechanism, the driving mechanism drives the drilling mechanism to be inserted into the soil, so as to obtain soil samples. The edge of the part of the drilling mechanism that contacts the soil is set to be thin and sharp sawtooth. The thinner edge has a smaller contact area with the soil during sampling, which can reduce the pressure of the sampler on the soil, so the damage to the terrain caused by the sampler inserted into the soil can be reduced. The sharp sawtooth shape can also make it easier for the sampler to be inserted into relatively hard soil.

[0017] 3. In the present invention, the cleaning and drying mechanism cooperates with the sampler. The cleaning and drying mechanism alternately sends a large amount of clean water and strong wind into the sampling tube through the reversing valve to clean the residual soil in the sampling tube, and then the residual water stains and the mixture of soil are blown out of the sampling tube by wind, so as to achieve the purpose of cleaning and drying the inner wall of the sampling tube. Manual operation only needs to control the reversing valve, which is easy to operate, does not require excessive manual intervention, has high cleaning efficiency, and the liberated workers can do other work in advance, which also improves the efficiency of soil sampling work;

[0018] 4. In the present invention, a plurality of drainage holes are provided at one end of the sampler close to the driving mechanism, so that the obtained samples can be more representative, because most of the soil exposed to the outside is strongly affected by weathering. After a long period of weathering and natural changes, the physical and chemical properties of the exposed soil will change. When sampling, the exposed outer part can be discharged by the drainage holes when entering the bottom of the sampler, so the obtained samples are all deep soil, which is more useful for reference in later structural analysis. When it is necessary to specially study the weathered outer part of the soil, a container can be set below the drainage hole so that the soil discharged from the drainage hole falls into the container and is collected.

[0034] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1 to Figure 8 As shown, this embodiment proposes a horizontal sampling soil drilling machine, including a base 1, a positioning mechanism 2, a driving mechanism 3, a drilling mechanism 4, a sampler 5 and a cleaning and drying mechanism 6. The positioning mechanism 2 is fixedly connected to the base 1 and is used to locate the sampling position. The driving mechanism 3 is fixedly connected to the positioning mechanism 2, and the driving mechanism 3 is located above the base 1. The drilling mechanism 4 is fixedly connected to the driving mechanism 3. The sampler 5 is slidably connected to the drilling mechanism 4. The cleaning and drying mechanism 6 is fixedly connected to the base 1, and the cleaning and drying mechanism 6 is fixedly connected to the drilling mechanism 4. When working, first inspect the position where sampling is required, clear the weeds, stones, garbage and other debris at the sampling position, adjust the positioning mechanism 2, and the positioning mechanism 2 adjusts the driving mechanism 3, the drilling mechanism 4 and the sampler 5 to the sampling position and locks them. The driving mechanism 3 is then started, driving the drilling mechanism 4 to insert the sampler 5 into the soil at the sampling position. After the sampling is completed, the sampler 5 is removed to collect the soil sample, and then the sampler 5 is installed back into the drilling mechanism 4, and the cleaning and drying mechanism 6 is opened. The cleaning and drying mechanism 6 cleans the inner wall of the sampler 5 and blows away the water stains and residues inside, and then performs drilling sampling at the next sampling position. The edge of the part of the drilling mechanism 4 in contact with the soil is set to a thin and sharp serration, which can make the sampler 5 easier to insert into the soil. The positioning mechanism 2 can bring stronger applicability to the device, reduce the time for debugging the sampling position, and be more efficient. The cleaning and drying mechanism 6 can cooperate with the timed working equipment, and automatically close the cleaning and drying mechanism 6 after cleaning, which liberates manpower, is easy to operate, and has high work efficiency.

[0036] The positioning mechanism 2 includes a support plate 21, a screw rod 22, a motor 23 and a rib plate 24. The support plates 21 are provided with two, and the two support plates 21 are fixedly connected to the base 1. The screw rods 22 are provided with two, and the two screw rods 22 are respectively rotatably connected in the two support plates 21. The motors 23 are provided with two, and the two motors 23 are fixedly connected to the base 1. The output ends of the two motors 23 are respectively fixedly connected to the two screw rods 22. The rib plates 24 are provided with two, and the two rib plates 24 are fixedly connected to the side walls of the support plate 21 for supporting the two When the support plate 21 and the positioning mechanism 2 start working, the motor 23 starts, and the motor 23 drives the screw rod 22 to rotate, and the screw rod 22 drives the mounting tube 32 threadedly connected thereto to move in the vertical direction. When it moves to the sampling position, the motor 23 stops working, and the self-locking property of the screw rod 22 fixes the mounting tube 32 at the sampling position. When the sampling position needs to be changed, the motor 23 can be started, and the screw rod 22 can be driven to rotate in different directions by the forward and reverse rotation of the motor 23, so as to adjust the sampling position, so that the device has stronger applicability.

[0037] Secondly, the driving mechanism 3 includes a support frame 31, a mounting tube 32 and a hydraulic cylinder 33. The support frame 31 is fixedly connected to the base 1, and the mounting tube 32 is set to be square. The mounting tube 32 is slidably connected to the support frame 31, and the mounting tube 32 is threadedly connected to the screw 22. The hydraulic cylinder 33 is fixedly connected in the mounting tube 32. When the driving mechanism 3 is working, the hydraulic cylinder 33 is first started. The hydraulic cylinder 33 pushes the sampler 5 to slide in the mounting tube 32, the support frame 31 and the support frame 51. The support frame 31 and the support frame 51 provide stability for the drilling sampling process. During drilling, the hydraulic cylinder 33 can provide sufficient power for the relatively hard soil, and the drilling sampling process is faster and more efficient. In addition, a through hole is opened at the top of the mounting tube 32 to provide heat dissipation for the hydraulic cylinder 33, thereby ensuring the normal and continuous operation of the hydraulic cylinder.

[0038] Again, the drilling mechanism 4 includes a sliding rod 41, a sampling tube 42 and a sampling drill bit 43. The sliding rod 41 is located in the mounting tube 32. One end of the sliding rod 41 is fixedly connected to the hydraulic cylinder 33. The sampling tube 42 is slidably connected to the sliding rod 41. The sampling drill bit 43 is fixedly connected to the sampling tube 42. A serrated cutting head is provided at the front end of the sampling drill bit 43. When the driving mechanism 3 drives the drilling mechanism 4 to take samples, the hydraulic cylinder 33 pushes the sliding rod 41 to move in the horizontal direction to complete the sampling in the horizontal direction. The serrated cutting head provided at the front end of the sampling drill bit 43 is smaller in thickness and serrated, so that the sampling tube 42 can be inserted into the soil more labor-savingly. During sampling, the sliding rod 41 slides in the sampling tube 42. When the hydraulic cylinder 33 pushes the sliding rod 41, the sliding rod 41 first moves forward until it is pressed against the limiting ring in the sampling tube 42. At this time, the sliding rod 41 blocks the output end of the water pipe 64 that sprays water into the sampling tube 42. At the same time, the sliding rod 41 pushes the sampling tube 42 into the soil. When the sampling tube 42 is pulled out of the soil, the sliding rod 41 is pulled out first. When the sliding rod 41 slides in the sampling tube 42 and presses against the limiting ring on the other side, the sliding rod 41 pulls the sampling tube 42 out. Then the sampling tube 42 is manually removed, the soil sample is taken out, and then installed back on the sliding rod 41.

[0039] Among them, the sampler 5 includes a support frame 2 51, a soil discharge hole 52 and a damping ring 53. The support frame 2 51 is fixedly connected to the support frame 1 31. There are multiple soil discharge holes 52. The multiple soil discharge holes 52 are opened on the end of the sampling tube 42 away from the sampling drill bit 43. The damping ring 53 is rotatably sleeved on the soil discharge hole 52 of the sampling tube 42. The damping ring 53 is provided with a through hole adapted to the soil discharge hole 52. When the sampler 5 is used, the hydraulic cylinder 33 pushes the sliding rod 41 to move on the support frame 2 51. There is a circular ring with the same diameter as the sampling tube 42 on the support frame 2 51. When the sampling tube 42 is inserted into the soil, it slides in the circular ring, so that the sampling tube 42 is inserted into the soil. When the sampling tube 42 is inserted into the soil, the surface soil enters the sampling tube 42 first. When the sampling tube 42 goes deep into the soil, the soil is constantly accumulated in the sampling tube 42. When the deep soil flows into the sampling tube 42, it will squeeze the shallow soil that enters the sampling tube 42 first. Therefore, the shallow soil that is not meaningful for sampling is continuously discharged through the soil discharge hole 52, and only the deep soil that is more useful for reference during analysis is retained in the sampling tube 42. After the sampling is completed, the damping ring 53 is rotated to block the soil discharge hole 52, so that water will not leak out from the soil discharge hole 52 during cleaning, thereby achieving the expected cleaning effect.

[0040] Secondly, the cleaning and drying mechanism 6 includes a water tank 61, a water pump 62, a reversing valve 63, a water pipe 64, a fan 65 and a spiral hose 66. The water tank 61 is fixedly connected to the base 1, the water pump 62 is fixedly connected to the water tank 61, the output end of the water pump 62 is divided into two, the reversing valve 63 is provided with two, the two reversing valves 63 are fixedly connected to the side wall of the sampling tube 42, the water pipe 64 is provided with four, and the four water pipes 64 are respectively connected to the output end of the water pump 62 and the two reversing valves 63, the fan 65 and the spiral hose 66. The fan 65 is fixedly connected to the sampling tube 42, the output end of the fan 65 is connected to the reversing valve 63, and two spiral hoses 66 are provided. Each spiral hose 66 is fixedly connected to two water pipes 64 located on the same side. After the sampling work is completed, the sampling tube 42 is installed back to the drilling mechanism 4, and then the residual soil in the sampling tube 42 is cleaned, and the water pump 62 is started. The water pump 62 pumps the water in the water tank 61 into the water pipe 64. At this time, the sliding rod 41 is pressed against the hydraulic cylinder 33. On the limiting ring on one side, at this time, the water pipe 64 is connected with the sampling tube 42, and the water in the water pipe 64 is sprayed into the sampling tube 42 to take away the soil in the sampling tube 42. The spiral hose 66 connected to the water pipe 64 has a certain elasticity, so that the water pipe 64 can move with the advancement of the sampling tube 42 for sampling, and the setting of the spiral hose 66 allows the cleaning and drying mechanism 6 to be fixed on the soil drilling rig all the time. Compared with the existing mechanism, the method of removing the drill bit for cleaning does not require manual Always pay attention to the cleaning progress of the drill bit. During cleaning, the samples can be further selected manually, or the location for the next sampling can be surveyed to make the sampling efficiency higher. Then, the water pump 62 is turned off, and the output end of the reversing valve 63 connected to the fan 65 is adjusted. The fan 65 is started, and a strong wind flow enters the sampling tube 42 through the reversing valve 63 to blow away the mixture of soil and clean water remaining in the sampling tube 42. Then, the next round of sampling is carried out with high efficiency, achieving the effect of simultaneously completing the cleaning and drying of the sampling tube 42.

[0041] Finally, the front section and the rear end of the sampling tube 42 are detachably connected to take out the soil collected by the sampling tube 42 .

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
