[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.

[0024] like Figure 1-Figure 4 As shown, a soil opener for geotechnical engineering investigation includes a shell 1, a fixed plate 11 is fixedly connected to the top of the outer wall of the shell 1, and four guide rods 12 are slidably connected to the inner wall of the fixed plate 11 in a circular array, and the bottom end of the guide rod 12 is fixedly connected to a soil breaking mechanism 2, and the top of the shell 1 is fixedly connected to a driving mechanism 3, the soil breaking mechanism 2 includes a movable plate 21, the top of the movable plate 21 is fixedly connected to the bottom end of the guide rod 12, and the driving mechanism 3 includes a telescopic cylinder 31, and the bottom end of the telescopic cylinder 31 is fixedly connected to the top of the shell 1.

[0025] The driving mechanism 3 drives the drill bit 39 to drill into the ground, so that the housing 1 can stand upright on the ground, avoiding the need for excessive manual effort to support it. At the same time, the driving mechanism 3 drives the earth-breaking mechanism 2 to break the soil layer on the ground for sampling.

[0026] like Figure 2 , Figure 3 As shown, the bottom end of the movable plate 21 is fixedly connected to four support rods 22 in a circular array, the bottom end of the support rods 22 is fixedly connected to a fixed frame 23, the outer wall of the fixed frame 23 is slidably connected to the bottom of the outer shell 1, one end of the fixed frame 23 is fixedly connected to a collecting frame 27, the inner wall of the fixed frame 23 is rotatably connected to a rotating rod 24, the outer wall of the rotating rod 24 is slidably connected to the bottom of the outer shell 1, one end of the rotating rod 24 is fixedly connected to a driven bevel gear 25, one end of the rotating rod 24 is rotatably connected to the inner cavity of the fixed frame 23, the outer wall of the rotating rod 24 is fixedly connected to a ground-breaking rake 26 in a circular array, and the highest point of the ground-breaking rake 26 is higher than the highest point of the fixed frame 23.

[0027] The active bevel gear 38 is meshed with the driven bevel gear 25, driving the driven bevel gear 25 to rotate, so that the driven bevel gear 25 drives the rotating rod 24 to rotate synchronously, and the rotating rod 24 drives the ground-breaking rake 26 to rotate synchronously. At this time, the ground-breaking rake 26 is in contact with the ground to carry out soil-breaking work. While breaking the soil, a small amount of soil broken by the ground-breaking rake 26 is driven by the ground-breaking rake 26 to be thrown upward and falls into the collecting frame 27, thereby facilitating the collection of soil samples, and completing soil-breaking and sampling at the same time, which speeds up work efficiency. At the same time, when carrying out soil-breaking work, multiple ground-breaking rakes 26 work at the same time, which increases the scope and efficiency of soil-breaking, increases work efficiency, and has the effect of increasing the scope of soil-breaking.

[0028] like Figure 2 , Figure 4As shown, the output end of the telescopic cylinder 31 is fixedly connected to a fixed block 32, the outer wall of the fixed block 32 is slidably connected to the top of the inner cavity of the shell 1, the inner cavity of the fixed block 32 is fixedly connected to a motor 33, and the output end of the motor 33 is fixedly connected to a rotating rod 2 34.

[0029] By starting the telescopic cylinder 31, the fixed block 32 is driven to move downward, so that the fixed block 32 drives the motor 33 to move downward synchronously, and the motor 33 drives the second rotating rod 34 to move downward synchronously.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, the outer wall of the rotating rod 34 is fixedly connected to the limiting ring 35, the outer wall of the limiting ring 35 is rotatably connected to the fixing ring 36, the inner wall of the fixing ring 36 is rotatably connected to the outer wall of the rotating rod 34, the outer wall of the fixing ring 36 is fixedly connected to four connecting rods 37 in a circular array, the outer wall of the connecting rod 37 is slidably connected to the inner wall of the outer shell 1, and one end of the connecting rod 37 is fixedly connected to the inner wall of the movable plate 21.

[0031] When the rotating rod 34 moves downward, it drives the limit ring 35 to move synchronously, and the limit ring 35 drives the fixed ring 36 to move synchronously, so that the fixed ring 36 drives the connecting rod 37 to move synchronously, and the connecting rod 37 drives the movable plate 21 to move synchronously, and the movable plate 21 drives the guide rod 12 to slide on the inner wall of the fixed plate 11, and the movable plate 21 is guided by the guide rod 12 so that the movable plate 21 will not deviate when moving downward.

[0032] like Figure 4 As shown, a driving bevel gear 38 is fixedly connected to the bottom of the second rotating rod 34 , and the outer wall of the driving bevel gear 38 is meshed with the outer wall of the driven bevel gear 25 . A drill bit 39 is fixedly connected to the bottom end of the second rotating rod 34 .

[0033] By starting the motor 33, the motor 33 drives the second rotating rod 34 to rotate, so that the second rotating rod 34 drives the drill bit 39 to rotate synchronously, so that the drill bit 39 drills underground. At the same time, the second rotating rod 34 drives the active bevel gear 38 to rotate synchronously, so that the active bevel gear 38 engages with the driven bevel gear 25. When the drill bit 39 enters the ground to a sufficient depth, the housing 1 can stand upright on the ground.

[0034] The working principle of the utility model is as follows: when in use, the device is moved to the designated working area, and then the motor 33 is started, and the motor 33 drives the rotating rod 24 to rotate, so that the rotating rod 24 drives the drill bit 39 to rotate synchronously, so that the drill bit 39 drills underground, and at the same time, the rotating rod 24 drives the active bevel gear 38 to rotate synchronously, so that the active bevel gear 38 meshes with the driven bevel gear 25, so that the driven bevel gear 25 drives the rotating rod 24 to rotate synchronously, and the rotating rod 24 drives the earth-breaking rake 26 to rotate synchronously. When the drill bit 39 enters the ground to a sufficient depth, at this time, the shell 1 stands upright on the ground, and the bottom end of the shell 1 contacts the ground, and the rotating earth-breaking rake 26 contacts the ground to carry out soil digging work. Then the telescopic cylinder 31 can be started, and the telescopic cylinder 31 drives the fixed block 32 to move downward, so that the fixed block 32 drives the motor 33 to move downward synchronously, and the motor 33 drives the rotating rod 24 to move downward synchronously, and the rotating rod 24 drives the limiting ring 35 to move synchronously, and the limiting ring 35 drives the fixing ring 36 to move synchronously.

At the same time, the movable plate 21 drives the supporting rod 22 to move synchronously, so that the supporting rod 22 drives the fixed frame 23 to move downward synchronously, and the fixed frame 23 drives the ground-breaking rake 26 to move downward synchronously, thereby further excavating the land and obtaining more samples, thereby achieving the effect of excavating and sampling. While excavating the land, a small amount of soil broken by the ground-breaking rake 26 is driven by the ground-breaking rake 26 to be thrown upward and fall into the collecting frame 27, thereby facilitating the collection of soil samples, and completing excavation and sampling at the same time, thereby speeding up the work efficiency. At the same time, when excavating the land, multiple ground-breaking rakes 26 work at the same time, which increases the scope and efficiency of excavating the land and increases the work efficiency, thereby greatly improving the user experience.
