[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0038] This embodiment mainly describes a quick-release type of underground drilling and digging machine that allows for rapid assembly and disassembly of the main unit and frame without the need for tools, as detailed below:

[0039] like Figure 1-13As shown, the quick-release hole drill includes a main unit 001, a frame 003, and a connecting assembly 002. The main unit 001 and the frame 003 are disassembled and assembled via the connecting assembly 002. The main unit 001 is provided with an operating frame 1 for holding. The operating frame 1 is provided with a connecting piece 2a and a connecting piece 2b. The connecting piece 2a and the connecting piece 2b are provided with through holes 21. The frame 003 is provided with a sleeve 9 located between the connecting piece 2a and the connecting piece 2b. The pipe hole 9a of the sleeve 9 is aligned with the through holes 21 of the connecting piece 2a and the connecting piece 2b. The connecting assembly 002 includes an operating component 5. The operating component 5 is provided with a plug section 5a that passes through the through hole 21 of the connecting piece and the pipe hole 9a of the sleeve 9. The plug section 5a extends out of the connecting piece 2a and the connecting piece 2b.

[0040] To prevent the operating component 5 from detaching from the sleeve 9, connecting piece 1 2a, and connecting piece 2b, the operating component 5 is provided with a limiting part 5b located outside the connecting piece 1 2a. A spring 7 is sleeved on the insertion section 5a, and the spring 7 is located between the limiting part 5b and the connecting piece 1 2a. A limiting component 6 is installed on the operating component 5, and the limiting component 6 is located outside the connecting piece 2b. The spring 7 acts elastically between the limiting part 5b and the connecting piece 1 2a, so that the limiting component 6 fits against the outer wall surface of the connecting piece 2b, thus preventing the connecting assembly 002 from detaching from the frame 003 and the operating frame 1.

[0041] In this embodiment, the end of the plug segment 5a that protrudes from the connecting piece 2b is provided with a receiving cavity 5c, and the cavity wall of the receiving cavity 5c is provided with a radially penetrating limiting groove 5d. The limiting groove 5d is connected to the end of the plug segment 5a. A rotating shaft 8 is provided in the receiving cavity 5c. The axis of the rotating shaft 8 is perpendicular to the penetrating direction of the limiting groove 5d. The limiting member 6 is rotatably connected to the rotating shaft 8. The limiting member 6 can rotate into the receiving cavity 5c or the limiting groove 5d.

[0042] When the limiting member 6 rotates into the receiving cavity 5c, the limiting member 6 is located in the receiving cavity 5c or the limiting groove 5d. The outer wall of the limiting member 6 will not exceed the outer wall of the insertion section 5a, or the outer wall size of the limiting member 6 is smaller than the inner diameter of the through hole 21 and the pipe hole 9a, so that the insertion section 5a of the operating member 5 can move through the through hole 21 and the pipe hole 9a. When the limiting member 6 rotates into the limiting groove 5d, both ends of the limiting member 6 are set beyond the outer wall of the insertion section 5a. At this time, the limiting member 6 can restrict the connecting assembly 002 from disengaging from the frame 003 and the operating frame 1.

[0043] In this application, through the installation of the operating component 5, spring 7, and limiting component 6, and the structural arrangement of the upper limit part 5b, limiting groove 5d, and storage cavity 5c of the operating component 5, when the operating component 5 of the connecting assembly 002 is connected to the connecting piece 2a, connecting piece 2b of the operating frame 1 and the sleeve 9 of the frame 003, the operating component 5 presses down, and the limiting part 5b of the operating component 5 compresses the spring 7 between the connecting piece 2a and the connecting piece 2b, so that the length of the upper limit groove 5d of the operating component 5 exposed above the connecting piece 2b increases. The limiting component 6 located in the limiting groove 5d can rotate, and when the limiting component 6 rotates into the storage cavity 5c, the connecting assembly 002 can be pulled out in the opposite direction of the pressing direction. That is, the connecting assembly 002 can be separated from the main unit 001 and the frame 003, and the connecting assembly 002 can be quickly assembled and disassembled from the frame 003 and the operating frame 1 without the aid of tools.

[0044] like Figure 3-4 As shown, the operating member 5 is also provided with an operating section 5e, and a limiting part 5b is located between the operating section 5e and the insertion section 5a. The operating section 5e has an L-shaped structure. Preferably, the operating section 5e can also have a flipped T-shaped structure, and the outer dimension of the limiting part 5b is larger than the outer diameter of the spring 7.

[0045] To prevent the operating frame 1 and the frame 003 from immediately separating and causing safety hazards when the connecting component 002 detaches from the operating frame 1 and the frame 003, hook pieces 3 are fixed on the connecting piece 1 2a and the connecting piece 2b. The hook piece 3 is provided with a hook hole 3a in the shape of a C or a semi-circular structure. The hook piece 3 is provided with a notch 3b that connects the hook hole 3a and the side wall of the hook piece 3. The sleeve 9 is inserted into the hook hole 3a and rotated. The sleeve 9 can only be detached from the hook hole 3a from the notch 3b. Preferably, the notch 3b can be provided with an opening at the top.

[0046] When connecting component 002 connects operating frame 1 and rack 003, the specific disassembly steps are as follows.

[0047] Step 1: As Figure 8 As shown, pressing the operating section 5e of the operating member 5 causes the limiting part 5b on the operating member 5 to compress the spring 7 of the connecting piece 2a on the operating frame 1, the limiting member 6 to move away from the outer wall of the connecting piece 2b, and the length of the upper limit groove 5d of the insertion section 5a of the operating member 5 exposed above the connecting piece 2b increases.

[0048] Step Two: As Figure 7 and Figure 9 As shown, the limiting member 6 is rotated so that the outer wall of the limiting member 6 does not exceed the outer wall of the insertion section 5a, or the outer wall size of the limiting member 6 is smaller than the inner diameter of the through hole 21 and the pipe hole 9a.

[0049] Step 3: As Figure 10 As shown, the connecting component 002 is pulled out in the opposite direction of the pressing direction, so that the connecting component 002 is separated from the operating frame 1 and the frame 003.

[0050] Step Four: As Figure 11-13 As shown, based on the disassembly of the connecting component 002, the sleeve 9 on the frame 003 disengages from the hook hole 3a at the notch 3b of the hook piece 3 of the operating frame 1, thereby separating the operating frame 1 from the frame 003.

[0051] Conversely, when connecting the connecting assembly 002, the operating frame 1, and the frame 003, the sleeve 9 on the frame 003 is pre-inserted into the hook hole 3a through the notch 3b of the hook piece 3, and then... Figure 7 In the current state, the operating member 5 of the connecting assembly 002 is inserted into the through hole 21 of the connecting piece 1 2a, the tube hole 9a of the sleeve 9, and the through hole 21 of the connecting piece 2b. The limiting part 5b on the operating member 5 compresses the spring 7 of the connecting piece 1 2a, causing the limiting member 6 passing through the connecting piece 2b to rotate to the position indicated by the compression spring 7 on the connecting piece 1 2a. Figure 5 When the pressure acting on the connecting component 002 is released, the spring 7 elastically returns to its original state, causing the limiting member 6 to adhere to the outer wall of the connecting piece 2b, restricting the rotation of the limiting member 6, and realizing the connection between the connecting component 002, the operating frame 1 and the frame 003.

[0052] like Figure 1-4 As shown, the frame 003 also includes a main rod 10, an extension rod 11, a crossbar 12, and a vertical rod 13. The main rod 10 is set diagonally downwards, and the sleeve 9 is inserted into the main rod 10 near one end. The extension rod 11 is connected to the other end of the main rod 10 through a snap fastener 14. The crossbar 12 is fixedly connected to the extension rod 11, and the crossbar 12 can be connected by welding or by butt joint of the snap fastener 14. The snap fasteners 14 can be fixed with bolts and nuts. A connecting post 10a is provided below the main rod 10, and the connecting post 10a forms an angle of less than 90° with the main rod 10. The vertical rod 13 is inserted into the connecting post 10a, and the vertical rod 13 is fixedly connected to the connecting post 10a with bolts and nuts. The vertical rod 13 can be raised and lowered on the connecting post 10a. The vertical rod 13 is set for support or movement when the hole drilling machine is not working.

[0053] Preferably, the main rod 10 is perpendicular to the sleeve 9, and the extension rod 11 is not required, so that the main rod 10 and the cross rod 12 are directly fixed, the cross rod 12 is parallel to the sleeve 9, the main rod 10 and the extension rod 11 are made of square tubes, and the male and female buckle 14 is made of square tube male and female buckle 14.

[0054] To facilitate the transport or operation of the main unit 001 driven by the frame 003, main wheels 15 are rotatably mounted at both ends of the crossbar 12, and auxiliary wheels 16 are rotatably mounted at the lower end of the upright 13. The auxiliary wheels 16 can be casters. When using the ground drilling and digging machine of this application, the upright 13 is removed, so that the ground drilling and digging machine uses the main wheels 15 in contact with the ground as the base point, holds the operating frame 1 of the main unit 001 and presses it down, and the main unit 001 can perform drilling or digging work. When the ground drilling and digging machine is transported during operation, it is moved forward or backward by lifting the operating frame 1 of the main unit 001.

[0055] In this embodiment, the operating frame 1 is provided with a rotation limiting part 1a. A rotation limiting component 4 can be fixed on the side wall of one end of the main rod 10 by welding or other means. The rotation limiting component 4 and the rotation limiting part 1a are in line-surface contact. When the main wheel 15 and auxiliary wheel 16 on the frame 003 roll and push against the ground, the main unit 001 will deflect downward around the axis of the insertion section of the operating component 5 due to gravity. The contact between the rotation limiting component 4 and the rotation limiting part 1a can limit the rotation between the frame 003 and the operating frame 1, ensuring the stability of the connection between the main unit 001 and the frame 003 when the main unit 001 holds the operating frame 1 and pushes the frame 003 forward or backward. Preferably, the rotation limiting component 4 can be a square tube, and the end face of the rotation limiting component 4 that is in contact with the rotation limiting part 1a is set obliquely downward and backward. The rotation limiting component 4 and the rotation limiting part 1a can also be in line-surface contact.

[0056] Preferably, when the main wheel 15 of the frame 003 is heavy enough, the frame 003 can limit the downward pressure of the main unit 001 due to gravity.

[0057] like Figure 3 , Figure 4 , Figure 12 and Figure 13 As shown, when the operating frame 1 separates from the frame 003 in step four, the frame 003 stands stably on the ground. By holding the operating frame 1 of the host 001 and sliding it down, the sleeve 9 of the frame 003 can be dislodged from the notch 3b, thus separating the frame 003 from the operating frame 1, i.e., the host 001.
