[0001] This utility model belongs to the field of infrastructure equipment, and in particular relates to a rectangular foundation trench drilling device for rapid excavation. Background Technology

[0002] In the construction process of civil engineering projects, it is often necessary to excavate rectangular foundation trenches at intervals. In existing technologies, workers can excavate using shovels, but manual excavation of rectangular foundation trenches is not only time-consuming and labor-intensive, but may also result in over- or under-excavation of the trench's dimensions and depth. Excavators can also be used, but excavation by excavators can also result in substandard dimensions and depths, leading to over- or under-excavation; furthermore, the movement structure of the excavator bucket limits the excavation of rectangular foundation trenches smaller than the bucket's dimensions. Therefore, there is an urgent need for those skilled in the art to propose a rectangular trench forming device that can quickly and accurately excavate rectangular foundation trenches to improve work efficiency. Utility Model Content

[0003] In view of this, the present invention provides a rectangular trench drilling device for rapid excavation, which is used to solve the above problems.

The mounting bracket is installed at the output end of an excavator, and multiple vibration devices are installed at the bottom end of the mounting bracket. The rectangular excavation frame is fixedly installed at the output ends of the multiple vibration devices. The auger soil removal device includes a drive device, a drill rod, and auger blades. The drive device is installed on the mounting bracket. The top end of the drill rod passes through the mounting bracket and is fixedly connected to the output end of the drive device. The drill rod passes through the rectangular excavation frame, and its bottom end extends out of the rectangular excavation frame. The drill rod is slidably connected to the top wall of the rectangular excavation frame. The auger blades are fixedly wound around the side wall of the drill rod, and soil removal holes are provided on the side wall of the rectangular excavation frame.

[0006] The vibration device is a pneumatic vibratory hammer, and multiple pneumatic vibratory hammers are installed at the bottom end of the mounting bracket. The rectangular hole-forming frame is fixedly installed at the output end of the multiple pneumatic vibratory hammers.

[0007] The driving device is a hydraulic motor, the mounting bracket is U-shaped, the hydraulic motor is installed in the mounting bracket, and the output end of the hydraulic motor is fixedly connected to the top end of the drill rod.

[0008] Furthermore, the two auger blades are fixedly wound around the side wall of the drill pipe.

[0009] Furthermore, the bottom end of the rectangular hole-forming frame is provided with a first tooth.

[0010] Furthermore, the bottom end of the auger blade is provided with a second tooth.

[0011] Furthermore, the auger soil removal device also includes multiple soil-breaking cones, which are installed at the bottom end of the auger blades.

The rectangular forming frame 20 is fixedly installed at the output end of the multiple vibration devices. The auger soil removal device 40 includes a drive device, a drill rod 42, and an auger blade 43. The drive device is installed on the mounting bracket 10, and the top end of the drill rod 42 passes through the mounting bracket 10 and is connected to the drive device. The output end of the device is fixedly connected, the drill rod 42 passes through the rectangular hole-forming frame 20 and extends out of the rectangular hole-forming frame 20 at the bottom end, and the drill rod 42 is slidably connected to the top wall of the rectangular hole-forming frame 20; the auger blade 43 is fixedly wound around the side wall of the drill rod 42, and the four side walls of the rectangular hole-forming frame 20 are provided with soil outlet holes 21; the bottom end of the rectangular hole-forming frame 20 is provided with a first tooth 22, which helps the rectangular hole-forming frame 20 to extend into the soil; the four side walls of the rectangular hole-forming frame 20 are also provided with scale lines 23, which can help to understand the hole depth of the rectangular foundation trench in a timely manner. Multiple vibrating devices vibrate the rectangular hole-forming frame 20 downwards, causing it to continuously extend into the soil. Simultaneously, the drive device drives the drill rod 42 to rotate and continuously drill into the soil, while also causing the auger blades 43 to rotate and break up the soil in the rectangular hole-forming frame 20. When the rectangular hole-forming frame 20 reaches the target depth, the drive device causes the auger blades 43 to rotate in the opposite direction, which can continuously transport the broken soil in the rectangular hole-forming frame 20 upwards and discharge it through the soil outlet holes 21 on the side wall of the rectangular hole-forming frame 20, thus realizing the rapid and efficient construction of the rectangular foundation trench.

[0030] Specifically, the vibration device is a pneumatic vibratory hammer 30, with multiple pneumatic vibratory hammers 30 mounted at the bottom of the mounting bracket 10. A rectangular hole-forming frame 20 is fixedly mounted on the output end of the multiple pneumatic vibratory hammers 30. The driving device is a hydraulic motor 41. The mounting bracket 10 is U-shaped, and the hydraulic motor 41 is mounted in the mounting bracket 10.

The auger soil removal device 40 also includes multiple soil-breaking cones 44, which are mounted at the bottom end of the auger blades 43.

[0031] Example 2

[0032] See attached document Figure 1-3 5 and 6, the difference between this embodiment and embodiment 1 is that the auger soil removal device 40 in this embodiment does not include a soil-breaking cone 44. Instead of a soil-breaking cone 44 at the bottom end of the auger blade 43, a second tooth 431 is provided at the bottom end of the auger blade 43. Figure 6 .

[0033] Example 3

[0034] The difference between this embodiment and embodiments 1 and 2 is that the rectangular trench drilling device for rapid excavation in this embodiment also includes multiple hydraulic cylinders 50. The multiple hydraulic cylinders 50 are respectively arranged between the rectangular drilling frame 20 and multiple pneumatic vibratory hammers 30. After the rectangular drilling frame 20 has excavated to a certain depth, the hydraulic cylinders 50 extend downward to push against the pneumatic vibratory hammers 30, which helps the rectangular drilling frame 20 to continue drilling into deeper soil.

[0035] Example 4

[0036] A method for rapidly excavating rectangular foundation trenches includes the following steps:

[0037] S1. Install the mounting bracket 10 on the output end of the excavator, so that the rectangular hole forming frame 20 and the drill rod 42 are vertically downward and located directly above the target trench to be constructed;

[0038] S2. The excavator brings the bottom end of the drill rod 42 against the center of the construction position on the ground, while the first tooth 22 touches the ground;

[0039] S3. Start the pneumatic vibratory hammer 30 and the hydraulic motor 41. The pneumatic vibratory hammer 30 continuously vibrates the rectangular hole-forming frame 20 downwards, and the rectangular hole-forming frame 20 continuously extends into the soil to cut out a rectangular foundation trench. At the same time, the hydraulic motor 41 drives the drill rod to rotate 42, so that the bottom end of the drill rod 42 gradually extends into the soil. The auger blades 43, along with the drill rod 42, continuously rotate to break up the soil in the rectangular hole-forming frame 20, and transfer the broken soil upwards in the rectangular hole-forming frame 20, and discharge the rectangular hole-forming frame 20 through the soil outlet 21.

[0040] S4. The hydraulic cylinder 50 extends downward to press against the pneumatic vibratory hammer 30, so that the rectangular hole-forming frame 20 continues to form a hole in the deeper soil. The drill rod 42 and the auger blade 43 rotate synchronously to transport the soil of the rectangular hole-forming frame 20 upward and remove it.

[0041] S5. The excavator pulls the rectangular drilling frame 20 out of the soil by retracting the mounting bracket 10 and the hydraulic cylinder 50, thus completing the drilling of the rectangular foundation trench.
