Description

Technical Field

[0001] This utility model relates to the field of soil-opening tools, and in particular to a portable soil-opening tool for geotechnical engineering investigation. Background Technology

[0002] The portable soil cutter for geotechnical engineering investigation is a tool specifically designed for soil sampling and soil cutting operations in geotechnical engineering investigation. It has the advantages of high efficiency and convenience, and can quickly and accurately complete soil sampling and soil cutting operations, thereby improving the work efficiency of geotechnical engineering investigation.

[0003] When using a soil sampler to collect soil samples, the sample tube needs to be inserted into the ground to collect samples at a specific depth. However, it is difficult to control the depth of the sample tube as it is pushed downwards, which makes it difficult to collect samples at a specific depth. This can affect the purity of the soil samples and lead to larger errors in the final survey data. Utility Model Content

[0004] This invention addresses the problem that, during the downward pushing of the insertion cylinder, it is difficult to control the depth of the cylinder, which makes it difficult to sample soil at a specific depth, thus affecting the purity of the soil and rock samples and leading to large errors in the final survey data. The proposed invention is a portable soil opener for geotechnical engineering surveys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable excavator for geotechnical engineering investigation, comprising a cylinder, a support rod fixedly connected to one end of the cylinder, a handle symmetrically fixedly connected to one end of the support rod, a push block slidably connected to the inner wall of the cylinder, a push rod fixedly connected to one side of the push block, the push rod being disposed on the inner wall of the cylinder and the support rod, a limiting device being disposed on the outer surface of the cylinder, the limiting device comprising a limiting block, the outer surface of the cylinder being slidably connected to the inner wall of the limiting block, a threaded rod being disposed on one side of the limiting block, a threaded cylinder being threadedly connected to the outer surface of the threaded rod, a stop block being fixedly connected to the outer surface of one end of the cylinder, a connecting block being fixedly connected to the outer surface of the support rod, the threaded cylinder being disposed on the inner wall of the stop block and the connecting block, a pedal being disposed on the outer surface of the support rod, and an adjustment device being disposed between the pedal and the support rod.

[0006] The effects achieved by the above-mentioned components are as follows: By setting a limiting block, under the action of the threaded rod and the threaded cylinder, rotating the threaded cylinder will cause the threaded rod to extend and retract on the inner wall of the threaded cylinder. When the threaded rod extends and retracts, it will cause the limiting block to slide on the outer surface of the insertion cylinder until the limiting block reaches the appropriate position. The limiting block can block the outer surface of the insertion cylinder, thus facilitating the pre-adjustment of the position of the limiting block according to the actual required sampling depth. Then, the insertion cylinder only needs to be inserted into the soil until the bottom of the limiting block abuts the ground to quickly sample the soil at a fixed depth, effectively reducing errors and improving the accuracy of the survey data. In addition, the overall size of the soil opener is small and the weight is light, making it easier to carry.

[0007] Preferably, the outer surface of the threaded cylinder is fixedly connected to two bearings, and the outer surfaces of the two bearings are respectively fixedly connected to the inner walls of the stop block and the connecting block.

[0008] The effect achieved by the above components is that by setting bearings, the friction between the threaded cylinder and the stop and connecting block can be reduced when rotating the threaded cylinder, making it easier to rotate the threaded cylinder.

[0009] Preferably, an operating block is fixedly connected to one end of the threaded cylinder, and the outer surface of the operating block is provided with protrusions.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded cylinder to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, one end of the threaded rod is fixedly connected to an installation block, the installation block is fixedly connected to one side of a limiting block by bolts, one side of the limiting block is fixedly connected to a retaining ring, and the outer surface of the installation block is inserted into the inner wall of the retaining ring.

[0012] The effect achieved by the above components is as follows: by setting the mounting block, inserting the mounting block into the inner wall of the retaining ring, and then using bolts to fix the mounting block and the limiting block, the threaded rod and the limiting block can be connected, and the limiting block can be easily disassembled, maintained and replaced.

[0013] Preferably, the outer surface of the insert has a plurality of scale lines evenly distributed.

[0014] The effect achieved by the above components is that by setting scale lines, the limit block can be adjusted more intuitively and accurately through the scale lines.

[0015] Preferably, the adjusting device includes an auxiliary ring, the outer surface of the support rod is slidably connected to the inner wall of the auxiliary ring, one end of the pedal is fixedly connected to the outer surface of the auxiliary ring, a threaded pin is threadedly inserted into the inner wall of the auxiliary ring, and a rotating block is fixedly connected to one end of the threaded pin.

[0016] The effect achieved by the above components is as follows: by setting an auxiliary ring, the auxiliary ring is pushed to slide on the outer surface of the support rod until the pedal reaches the appropriate position. Then, the threaded pin is rotated so that one end of the threaded pin abuts against the outer surface of the support rod, which can fix the pedal and the support rod. This makes it easier to adjust the position of the pedal according to actual needs, and can effectively improve the practicality of the soil opener.

[0017] Preferably, a spring is fitted on the outer surface of the threaded pin, one end of the spring is fixedly connected to the outer surface of the auxiliary ring, and the other end of the spring is fixedly connected to a circular ring, one side of the circular ring being rotatably connected to one side of the rotating block.

[0018] The effects achieved by the above components are as follows: by setting a spring, the threaded pin connected to the rotating block can be connected to the auxiliary ring, which helps to prevent the threaded pin from easily detaching from the inner wall of the auxiliary ring and potentially being lost. At the same time, by setting a ring, one side of the rotating block can be connected to the spring, which helps to prevent the rotating block from driving the spring to rotate and causing damage to the spring.

[0019] Preferably, the outer surface of the support rod is provided with an auxiliary groove, and a rubber strip is fixedly connected to the inner wall of the auxiliary groove, and the inner wall of the auxiliary ring abuts against the outer surface of the rubber strip.

[0020] The effect achieved by the above components is that by setting a rubber strip, the outer surface of the support rod can be replaced to abut against one end of the threaded pin, and the friction between the threaded pin and the support rod can be increased, thereby making the threaded pin more securely fixed to the pedal.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a limiting block, the threaded rod can drive the limiting block to slide on the outer surface of the insert until the limiting block reaches the appropriate position. The limiting block can block the outer surface of the insert, thus facilitating the pre-adjustment of the position of the limiting block according to the actual required sampling depth. Then, the insert only needs to be inserted into the soil until the bottom of the limiting block abuts against the ground to quickly sample the soil at a fixed depth and effectively reduce errors.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a portable excavator for geotechnical engineering investigation, including an insert 1. The insert 1 is characterized by: a support rod 2 fixedly connected to one end; a handle 3 symmetrically fixedly connected to one end of the support rod 2; a push block 4 slidably connected to the inner wall of the insert 1; a push rod 5 fixedly connected to one side of the push block 4; the push rod 5 is disposed on the inner wall of the insert 1 and the support rod 2; a limiting device 6 is provided on the outer surface of the insert 1; the limiting device 6 includes a limiting block 61; the outer surface of the insert 1 is slidably connected to the inner wall of the limiting block 61; a threaded rod 62 is provided on one side of the limiting block 61; a threaded cylinder 63 is threadedly connected to the outer surface of the threaded rod 62; a stop block 64 is fixedly connected to the outer surface of one end of the insert 1; a connecting block 65 is fixedly connected to the outer surface of the support rod 2; the threaded cylinder 63 is disposed on the inner wall of the stop block 64 and the connecting block 65; and a threaded cylinder 63 is disposed on the outer surface of the support rod 2. A foot pedal 7 is provided, and an adjustment device 8 is set between the foot pedal 7 and the support rod 2. By setting a limiting block 61, under the action of the threaded rod 62 and the threaded cylinder 63, the threaded cylinder 63 is rotated. The threaded cylinder 63 will drive the threaded rod 62 to extend and retract on the inner wall of the threaded cylinder 63. When the threaded rod 62 extends and retracts, it will drive the limiting block 61 to slide on the outer surface of the insertion tube 1 until the limiting block 61 reaches the appropriate position. The limiting block 61 can block the outer surface of the insertion tube 1, so that the position of the limiting block 61 can be adjusted in advance according to the actual required sampling depth. Then, the insertion tube 1 only needs to be inserted into the soil until the bottom of the limiting block 61 abuts the ground, which can quickly sample the soil at a fixed depth, effectively reduce errors, improve the accuracy of the survey data, and the overall size of the soil opener is small and the weight is light, making it easier to carry.

[0029] Reference Figure 2 and Figure 3 As shown, two bearings 66 are fixedly connected to the outer surface of the threaded cylinder 63. The outer surfaces of the two bearings 66 are fixedly connected to the inner walls of the stop block 64 and the connecting block 65, respectively. By setting the bearings 66, the friction between the threaded cylinder 63 and the stop block 64 and the connecting block 65 can be reduced when rotating the threaded cylinder 63, making it easier to rotate the threaded cylinder 63. An operating block 67 is fixedly connected to one end of the threaded cylinder 63. The outer surface of the operating block 67 is provided with protrusions. By setting the operating block 67, rotating the operating block 67 can drive the threaded cylinder 63 to rotate. At the same time, the protrusions on the outer surface of the operating block 67 can effectively increase the friction on the outer surface of the operating block 67, which has an anti-slip effect when rotating the operating block 67.

[0030] Reference Figure 2 and Figure 3 As shown, one end of the threaded rod 62 is fixedly connected to an installation block 68. The installation block 68 is fixedly connected to one side of the limiting block 61 by bolts. A retaining ring 69 is fixedly connected to one side of the limiting block 61. The outer surface of the installation block 68 is inserted into the inner wall of the retaining ring 69. By setting the installation block 68, inserting the installation block 68 into the inner wall of the retaining ring 69, and then fixing the installation block 68 and the limiting block 61 with bolts, the threaded rod 62 and the limiting block 61 can be connected. At the same time, it is also convenient to disassemble, maintain and replace the limiting block 61. Several scale lines 610 are evenly opened on the outer surface of the insert 1. By setting the scale lines 610, it is convenient to make a more intuitive and precise adjustment of the limiting block 61 through the scale lines 610.

[0031] Reference Figure 2 and Figure 4 As shown, the adjusting device 8 includes an auxiliary ring 81. The outer surface of the support rod 2 is slidably connected to the inner wall of the auxiliary ring 81. One end of the pedal 7 is fixedly connected to the outer surface of the auxiliary ring 81. A threaded pin 82 is threadedly inserted into the inner wall of the auxiliary ring 81. One end of the threaded pin 82 is fixedly connected to a rotating block 83. By setting the auxiliary ring 81, the auxiliary ring 81 is pushed to slide on the outer surface of the support rod 2 until the pedal 7 reaches the appropriate position. Then, the threaded pin 82 is rotated so that one end of the threaded pin 82 abuts against the outer surface of the support rod 2, thereby fixing the pedal 7 and the support rod 2. This facilitates the adjustment of the position of the pedal 7 according to actual needs, effectively improving the practicality of the soil opener.

[0032] Reference Figure 2 and Figure 4As shown, a spring 84 is fitted onto the outer surface of the threaded pin 82. One end of the spring 84 is fixedly connected to the outer surface of the auxiliary ring 81, and the other end of the spring 84 is fixedly connected to a ring 85. One side of the ring 85 is rotatably connected to one side of the rotating block 83. By setting the spring 84, the threaded pin 82 connected to the rotating block 83 can be connected to the auxiliary ring 81, which helps to prevent the threaded pin 82 from easily detaching from the inner wall of the auxiliary ring 81 and potentially being lost. At the same time, by setting the ring 85, one side of the rotating block 83 can replace the spring. The connection between 84 helps prevent the rotating block 83 from driving the spring 84 to rotate and causing damage to the spring 84. An auxiliary groove 86 is provided on the outer surface of the support rod 2. A rubber strip 87 is fixedly connected to the inner wall of the auxiliary groove 86. The inner wall of the auxiliary ring 81 abuts against the outer surface of the rubber strip 87. By setting the rubber strip 87, it can replace the outer surface of the support rod 2 to abut against one end of the threaded pin 82 and increase the friction between the threaded pin 82 and the support rod 2, thereby making the threaded pin 82 more firmly fixed to the pedal 7.

[0033] Working principle: Rotating the operating block 67 drives the threaded cylinder 63 to rotate. The threaded cylinder 63 then causes the threaded rod 62 to extend and retract within the inner wall of the threaded cylinder 63. During this extension and retraction, the threaded rod 62 causes the limiting block 61 to slide on the outer surface of the insert 1 until the limiting block 61 reaches the appropriate scale line 610. The limiting block 61 can block the outer surface of the insert 1, thus facilitating the pre-adjustment of the position of the limiting block 61 according to the actual required sampling depth. Then, simply insert the insert 1 into the soil until the bottom of the limiting block 61 contacts the ground to achieve the desired sampling depth. Rapid soil sampling at a fixed depth can effectively reduce errors. When the position of the pedal 7 needs to be adjusted, the auxiliary ring 81 is pushed to slide on the outer surface of the support rod 2 until the pedal 7 reaches the appropriate position. Then, the rotating block 83 is rotated to drive the threaded pin 82 to rotate, so that the spring 84 is continuously compressed by the rotating block 83 and the ring 85 until one end of the threaded pin 82 abuts against the rubber strip 87 on the outer surface of the support rod 2. This can fix the pedal 7 and the support rod 2, and make it easy to adjust the position of the pedal 7 according to actual needs.
