Description

Technical Field

[0001] This utility model relates to the field of soil exploration technology, and in particular to a device for exploring the layered structure of hard soil. Background Technology

[0002] Soil layer structure investigation is crucial in engineering construction and agricultural production. It typically involves systematic exploration, precise analysis, and detailed recording of soil layers at different depths. In engineering projects, it determines foundation bearing capacity, landslide risk, and settlement potential. In agricultural production, it reveals the distribution of the topsoil, water-retaining layer, and saline-alkali layer, guiding irrigation and fertilization. Furthermore, it allows for the detection of heavy metals and petroleum contaminants in the soil.

[0003] However, soil properties vary significantly across different regions, with some areas exhibiting soft characteristics and others hard ones. This difference in soil hardness, especially when encountering hard soil, often causes considerable inconvenience to soil structure investigation. Furthermore, the generally large size of the investigation equipment also poses challenges for on-site personnel in terms of transportation and carrying.

[0004] Therefore, this application provides an apparatus for investigating the layered structure of hard soil to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for exploring the layered structure of hard soil. This device provides a more ideal exploration effect in the layered structure of hard soil and also improves the convenience of transportation and carrying.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A layer structure exploration device for hard soil includes a fixed handrail, an output source, an inner drill rod, and an outer drill cylinder. The fixed handrail includes a motor fixing sleeve. The upper two sides of the outer wall of the motor fixing sleeve are fixedly connected to the handrail body by two No. 1 screws. A fixing frame is fixedly installed on the lower end face of the outer wall of the motor fixing sleeve. A bearing is fixedly installed on the inner bottom surface of the fixing frame.

[0008] The output source includes a motor body, and a connecting seat is fixedly connected to the output end of the motor body. A connecting fixing sleeve is fixedly sleeved on the outer wall of the connecting seat.

[0009] The drill bit inner rod includes an outer cylinder cover, a connector is fixedly provided on the upper end face of the outer cylinder cover, a spiral blade is fixedly provided on the outer cylinder cover, and a stepped drill bit is fixedly provided on the lower end face of the spiral blade;

[0010] The drill bit outer cylinder includes a drill tube, and a hollow drill is fixedly disposed on the lower end face of the drill tube.

[0011] Furthermore, a groove is provided on the upper end face of the rear end of the outer wall of the motor fixing sleeve.

[0012] Furthermore, the motor mounting sleeve is installed on the middle of the outer wall of the motor body using four No. 1 screws on both sides.

[0013] Furthermore, the connector is slidably fitted inside the connecting fixing sleeve, and the connector is fixed inside by two No. 2 screws on both sides and at both ends of the outer wall of the connecting fixing sleeve.

[0014] Furthermore, the drill barrel is rotatably disposed inside the bearing.

[0015] Furthermore, the outer cylinder cover is fitted onto the upper end face of the outer wall of the drill barrel.

[0016] Furthermore, the outer cylinder cover is fixed to the upper end face of the outer wall of the drill barrel by two No. 3 screws on both sides and at both ends of the outer wall.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model proposes a device for exploring the layered structure of hard soil. A hollow drill penetrates the soil layers by rotating and cutting the soil, a stepped drill bit cuts the soil into layers, and then a spiral blade feeds the soil into the drill barrel. It can not only effectively break through hard soil, but also maintain the original layered structure of the soil.

[0019] 2. The present invention proposes a device for exploring the layered structure of hard soil. By unscrewing the No. 1 screw, the motor fixing sleeve and the handle body can be removed. Unscrewing the No. 2 screw allows the connecting head of the drill bit inner rod to be separated from the connecting fixing sleeve. Then, unscrewing the No. 3 screw allows the outer cylinder cover to be separated from the drill cylinder. The device can be disassembled, making it more convenient to carry and transport.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a layered structure exploration device for hard soil, including a fixed handle 1, an output source 2, an inner drill rod 3, and an outer drill cylinder 4. The fixed handle 1 includes a motor fixing sleeve 101. The upper two sides of the outer wall of the motor fixing sleeve 101 are fixedly connected to the handle body 102 by two No. 1 screws 105. A fixing frame 103 is fixedly installed on the lower end face of the outer wall of the motor fixing sleeve 101. A bearing 104 is fixedly installed on the inner bottom surface of the fixing frame 103. A groove 106 is opened on the upper end face of the rear end of the outer wall of the motor fixing sleeve 101. The motor fixing sleeve 101 is installed in the middle of the outer wall of the motor body 201 by four No. 1 screws 105 on both sides. The drill cylinder 401 is rotatably installed inside the bearing 104.

[0031] Specifically, the handle body 102 allows for better control of the direction of force applied by the motor body 201, preventing drilling deviation from affecting the accuracy of soil sample collection. The bearing 104 prevents the drill barrel 401 from swinging erratically, effectively suppressing swaying and ensuring operational stability.

[0032] Reference Figure 2 , Figure 4The output source 2 includes a motor body 201, and a connecting seat 202 is fixedly connected to the output end of the motor body 201. A connecting fixing sleeve 204 is fixedly sleeved on the outer wall of the connecting seat 202.

[0033] Specifically, assemble the device when needed and use it. When transporting or carrying it, disassemble it to prevent it from being unable to fit in due to insufficient space.

The outer cylinder cover 302 is sleeved on the upper end face of the outer wall of the drill barrel 401.

[0035] Specifically, the stepped drill bit 304 cuts the soil into layers, while the spiral blades 303 maintain the original layer structure of the soil and store soil samples inside the drill barrel 401.

[0036] Reference Figure 2 , Figure 7 The drill bit outer cylinder 4 includes a drill cylinder 401. A hollow drill 402 is fixedly installed on the lower end face of the drill cylinder 401. The outer cylinder cover 302 is fixed to the upper end face of the outer wall of the drill cylinder 401 by two No. 3 screws 305 on both sides and at both ends of the outer wall.

[0037] Specifically, the outer cylinder cover 302 and the drill barrel 401 are fastened together by screw No. 305. The outer cylinder cover 302 drives the drill barrel 401 to rotate together, and the hollow drill 402 penetrates the soil layer by rotating and cutting the soil.

[0038] Working principle: When the operator needs to use the device, first, the motor fixing sleeve 101 is fitted onto the outer wall of the motor body 201. Then, the handrail body 102 is placed on both sides of the motor fixing sleeve 101, and the handrail body 102 and the motor fixing sleeve 101 are fixed with multiple No. 1 screws 105. The connector 301 is inserted into the connecting fixing sleeve 204 and aligned with the connecting seat 202, and then tightened with multiple No. 2 screws 203. Finally, the drill barrel 401 is fitted onto the outer wall of the spiral blade 303, inserted upwards into the interior of the outer cylinder cover 302, and tightened on the outer cylinder cover 302 with multiple No. 3 screws 305. When not in use, the multiple No. 1 screws 105, No. 2 screws 203, and No. 3 screws 305 can be unscrewed, and then the multiple parts can be disassembled.
