Description

Technical Field

[0001] The utility model relates to the technical field of soil drilling, in particular to a drilling device for soil detection. Background Technique

[0002] A drilling device for soil detection, usually called a soil sampler or a soil drilling machine, is a device used to extract soil samples from underground. Such a device is very important in the fields of geological exploration, environmental monitoring, agricultural research, construction, and archaeology. In geological exploration, soil samplers are used to obtain soil samples at different depths underground to analyze the composition, structure, and physical properties of the soil, which is crucial for evaluating geological stability and mineral resource development. Environmental scientists use soil samplers to detect soil pollution, including heavy metals, organic pollutants, and radioactive substances, etc., to assess environmental risks and develop treatment plans. In the agricultural field, soil samplers are used to collect soil samples and analyze soil fertility, pH value, organic matter content, etc., to help farmers optimize soil management and crop planting. Before construction, it is necessary to use a soil sampler to evaluate the bearing capacity of the foundation soil to ensure the safety and stability of the building. Archaeologists use soil samplers to explore underground relics and collect soil samples to analyze human activities and environmental changes in historical periods.

[0003] When the currently used soil sampler is in use, the device for positioning is difficult to lift and lower synchronously with the sampling device, resulting in the sampling position being prone to deviation during the sampling process. Therefore, a drilling device for soil detection is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drilling device for soil detection, which has the advantage of accurately positioning the sampling device to avoid deviation of the sampling position, and solves the problem that the currently used sampling device is prone to position deviation during use.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A drilling device for soil detection, including a sampling cylinder, a connecting frame is fixedly installed at the top of the sampling cylinder, a push rod is movably inserted into the connecting frame, and further includes a limiting frame;

[0006] The limiting frame is movably installed on the push rod above the connecting frame;

[0007] Wherein, a positioning rod is movably installed on the limiting frame.

[0008] When using a drilling device for soil detection in this technical solution, weld and install the connecting frame on the top of the sampling cylinder to ensure stable connection. Insert the push rod into the connecting frame from the bottom of the sampling cylinder. A push plate is fixedly installed at the bottom end of the push rod. The limiting frame is movably installed on the push rod, and the limiting ring is adjusted to adapt to the rotation of the push rod. The positioning rod is movably installed on the limiting frame through a reserved groove. A pedal is fixedly installed at the top of the positioning rod. Step on the pedal to insert the bottom end of the positioning rod into the soil and make the bottom end of the sampling cylinder perpendicular to the ground. The spiral side plate at the bottom of its outer wall helps to drill into the soil. Rotate the push rod through the handle to make the sampling cylinder move downward and penetrate into the soil to the required depth. During this process, continuously apply force to the positioning rod so that the positioning rod enters the soil together with the sampling cylinder. When the sampling cylinder reaches the required depth, pull the sampling cylinder through the push plate at the bottom end of the push rod, pull out the sampling cylinder containing the soil sample from the soil. After the sampling cylinder is lifted out of the ground, push out and collect the soil sample from the sampling cylinder through the push plate.

[0009] Preferably, the sampling cylinder is designed with stainless steel material, and a spiral side plate is fixedly installed at the bottom of the outer wall of the sampling cylinder.

[0010] Designed with stainless steel material, it improves durability and corrosion resistance and is suitable for use in various soil environments.

[0011] The spiral side plate fixedly installed at the bottom of the outer wall helps the drilling device to penetrate deep into the soil layer during rotation. The spiral structure can reduce the resistance when inserting into the soil and improve the sampling efficiency.

[0012] Preferably, the connecting frame is welded and installed on the top of the sampling cylinder, and a hexagonal through-hole is opened at the top of the connecting frame.

[0013] The connecting frame is welded and installed on the top of the sampling cylinder, providing a firm connection and ensuring stability during the drilling process.

[0014] The hexagonal through-hole opened at the top can be used for the installation of the push rod to rotate the connecting frame through the push rod.

[0015] Preferably, the bottom end of the push rod passes through the through-hole on the connecting frame and a push plate is fixedly installed. An insertion slot is opened at the top of the push rod, and a handle is movably inserted into the insertion slot.

[0016] The insertion slot at the top of the push rod allows the handle to be movably inserted, providing flexibility and convenience during operation.

[0017] Preferably, the cross-sectional dimension of the push plate is smaller than the inner diameter dimension of the sampling cylinder, and the bottom end of the push plate is designed with a conical structure.

[0018] The cross-sectional dimension of the push plate is smaller than the inner diameter dimension of the sampling cylinder, ensuring that the push plate can move smoothly in the sampling cylinder without getting stuck or hindering the sampling process.

[0019] Preferably, a limiting ring is rotatably installed inside the limiting frame, and a limiting ball is fixedly installed outside the limiting frame.

[0020] Preferably, the limiting ring is movably sleeved on the push rod, and the push rod is rotatably connected to the limiting frame through the limiting ring.

[0021] The rotational connection between the limiting ring inside the limiting frame and the push rod provides flexibility, allowing the push rod to rotate within the limiting frame.

[0022] Preferably, a reserved groove is provided on the positioning rod, and the positioning rod is movably installed on the limiting frame through the reserved groove. A stepping pedal is fixedly installed at the top of the positioning rod.

[0023] The reserved groove on the positioning rod allows the positioning rod to be movably installed on the limiting frame, providing the functions of adjustment and positioning to adapt to the soil sampling requirements at different depths.

[0024] The design of the stepping pedal at the top provides an additional operation method, enabling the application of additional thrust by foot when needed to improve the operation efficiency.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0026] The present utility model provides a stable base for the entire device by setting a limiting frame, movably installing the limiting frame on the push rod above the connecting frame, movably installing a positioning rod on the limiting frame, and fixedly installing a connecting frame at the top of the sampling cylinder. This ensures stability during operation and reduces the deviation of the sampling position caused by the movement of the device. The push rod is movably inserted into the connecting frame, meaning that the push rod can move freely to a certain extent but is restricted within the range of the connecting frame. This helps with fine adjustment during the drilling process while maintaining a relatively stable position. The limiting frame is movably installed on the push rod, which can move along with the push rod while restricting the movement range of the push rod to prevent it from deviating from the predetermined sampling position. The positioning rod is movably installed on the limiting frame, providing additional positioning points. The positioning rod can be adjusted as needed to adapt to different sampling depths and positions. The reserved groove provided on the positioning rod allows for precise adjustment of the positioning rod on the limiting frame. By changing the position of the limiting frame within the reserved groove, precise control of the sampling depth can be achieved. The design and coordinated use of the connecting frame, push rod, limiting frame, and positioning rod work together for precise positioning, achieving the advantage of precisely positioning the sampling device during the sampling process to avoid deviation of the sampling position.

Embodiment

[0034] As Figures 1 to 5 shown, an embodiment provided by the present utility model: A drilling device for soil detection, including a sampling cylinder 5, a connecting frame 11 is fixedly installed at the top of the sampling cylinder 5, a push rod 1 is movably inserted in the connecting frame 11, and further includes a limit frame 3;

[0035] Specifically, by setting the limit frame 3 and movably installing the limit frame 3 on the push rod 1 above the connecting frame 11, and movably installing a positioning rod 6 on the limit frame 3, the top of the sampling cylinder 5 is fixedly installed with the connecting frame 11, which provides a stable base for the entire device, ensuring stability during operation and reducing the deviation of the sampling position caused by the movement of the device. The push rod 1 is movably inserted into the connecting frame 11, which means that the push rod 1 can move freely to a certain extent but is restricted within the range of the connecting frame 11 at the same time. This helps to make fine adjustments during the drilling process while maintaining a relatively stable position. The limit frame 3 is movably installed on the push rod 1, which can move along with the movement of the push rod 1 but restricts the movement range of the push rod 1 to prevent it from deviating from the predetermined sampling position. The positioning rod 6 is movably installed on the limit frame 3, providing an additional positioning point. The positioning rod 6 can be adjusted as needed to adapt to different sampling depths and positions. The reserved slot 9 opened on the positioning rod 6 allows the positioning rod 6 to be precisely adjusted on the limit frame 3. By changing the position of the limit frame 3 in the reserved slot 9, precise control of the sampling depth can be achieved. The design and combined use of the connecting frame 11, push rod 1, limit frame 3, and positioning rod 6 act together for precise positioning, achieving the advantage of precisely positioning the sampling device during the sampling process to avoid the deviation of the sampling position.

[0038] The spiral side plate 4 fixedly installed at the bottom of the outer wall helps the drilling device to penetrate deep into the soil layer when rotating. The spiral structure can reduce the resistance when inserting into the soil and improve the sampling efficiency.

[0039] Furthermore, the connecting frame 11 is welded and installed on the top of the sampling cylinder 5, and a hexagonal through hole is opened at the top of the connecting frame 11.

[0040] The connecting frame 11 being welded and installed on the top of the sampling cylinder 5 provides a firm connection, ensuring stability during the drilling process.

[0041] The hexagonal through hole opened at the top can be used for the installation of the push rod 1 to rotate the connecting frame 11 through the push rod 1.

[0042] Furthermore, the bottom end of the push rod 1 passes through the through hole on the connecting frame 11 and is fixedly installed with a push plate 10. An insertion slot 12 is opened at the top of the push rod 1, and a grip rod 2 is movably inserted into the insertion slot 12.

[0043] The insertion slot 12 at the top of the push rod 1 allows the grip rod 2 to be movably inserted, providing flexibility and convenience during operation.

[0044] Furthermore, the cross-sectional dimension of the push plate 10 is smaller than the inner diameter dimension of the sampling cylinder 5, and the bottom end of the push plate 10 is designed with a conical structure.

[0045] The cross-sectional dimension of the push plate 10 being smaller than the inner diameter dimension of the sampling cylinder 5 ensures that the push plate 10 can move smoothly within the sampling cylinder 5 without getting stuck or hindering the sampling process.

[0046] Furthermore, a limiting ring 8 is rotatably installed inside the limiting frame 3, and a limiting ball 13 is fixedly installed outside the limiting frame 3.

[0047] Furthermore, the limiting ring 8 is movably sleeved on the push rod 1, and the push rod 1 is rotatably connected to the limiting frame 3 through the limiting ring 8.

[0048] The rotational connection between the limiting ring 8 inside the limiting frame 3 and the push rod 1 provides flexibility, allowing the push rod 1 to rotate within the limiting frame 3.

[0049] Furthermore, a reserved groove 9 is provided on the positioning rod 6, and the positioning rod 6 is movably installed on the limiting frame 3 through the reserved groove 9. A foot pedal 7 is fixedly installed at the top of the positioning rod 6.

[0050] The reserved groove 9 on the positioning rod 6 allows the positioning rod 6 to be movably installed on the limiting frame 3, providing functions of adjustment and positioning to adapt to soil sampling requirements at different depths.

[0051] The foot pedal 7 at the top is designed to provide an additional operation method, enabling the application of additional thrust by foot when needed to improve operation efficiency.

The push rod 1 is inserted into the connecting frame 11 from the bottom of the sampling cylinder 5. A push plate 10 is fixedly installed at the bottom end of the push rod 1. The limiting frame 3 is movably installed on the push rod 1. The limiting ring 8 is adjusted to adapt to the rotation of the push rod 1. The positioning rod 6 is movably installed on the limiting frame 3 through the reserved groove 9. A foot pedal 7 is fixedly installed at the top of the positioning rod 6. Step on the foot pedal 7 to insert the bottom end of the positioning rod 6 into the soil, and keep the bottom end of the sampling cylinder 5 perpendicular to the ground. The spiral side plate 4 at the bottom of its outer wall helps to drill into the soil. Rotate the push rod 1 through the grip rod 2 to make the sampling cylinder 5 move downward and penetrate into the soil to the required depth. During this process, continuously apply force to the positioning rod 6, so that the positioning rod 6 enters the soil together with the sampling cylinder 5.
