Description

Technical Field

[0001] The invention relates to the field of civil engineering and mechanical technology, and in particular to a high-efficiency hole digging drill bit. Background Art

[0002] In practice, digging holes is often required in civil engineering and other fields. The traditional construction method of manually digging holes with a long-handled shovel is difficult to meet the depth and quality requirements; at the same time, it has high operating intensity and poor work reliability. Summary of the invention

[0003] In view of this, in order to solve the problems existing in the technical background, the present invention proposes an efficient hole digging drill bit, and the specific technical solution is as follows:

[0004] An efficient hole-digging drill bit comprises a tool head and a tool rod, wherein the tool head is fixedly connected to the lower end of the tool rod, and the tool head is in an umbrella-shaped structure and can be opened and closed;

[0005] The tool head comprises a blade group and a connecting rod, the blade group is arranged around the support rod, and each blade of the blade group is connected to the support rod through the connecting rod thereon;

[0006] The support rod is provided with a handle and a soil-dividing shovel, wherein the soil-dividing shovel is arranged above the handle, and the side wall of the support rod is provided with an opening along its length direction, and a circle of the connecting rod is embedded in the opening and can move up and down along the height direction of the opening.

[0007] Furthermore, a buckle is provided on the outer wall of the connection between the handle and the soil-dividing shovel corresponding to the support rod, and the handle and the soil-dividing shovel can be clamped in the support rod by rotating around the support rod to prevent the handle and the soil-dividing shovel from shifting.

[0008] Furthermore, the outer wall of the handle is frosted.

[0009] Furthermore, a spring is arranged inside the handle, and a switch is arranged on the outer wall of the handle. When the switch is turned on, the handle drives the connecting rod to open the blade assembly in an umbrella shape.

[0010] Furthermore, the support rod is in the shape of a tube with an internal opening.

[0011] Furthermore, the soil dividing shovel is a cylindrical rod.

[0012] Furthermore, the blade group includes a plurality of identical blades.

[0013] The above technical solution has the following beneficial effects:

[0014] The present invention includes an umbrella-shaped structure composed of a tool head and a tool rod, and the tool head is spear-shaped. The tool head includes a blade group and a connecting rod. The blade group can be opened and closed as needed during use, and can be used for various hard soil layers. It saves time and effort to enter the soil layer until the drilling is completed. After the drilling is completed, the debris left by the drilling is within the range of the blade group enclosure and will not scatter everywhere. The present invention has a reasonable structural design, is simple and compact, has high efficiency, and is suitable for popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: See Figure 1-3 The high-efficiency hole-digging drill bit shown comprises a tool head and a tool stem, wherein the tool head is fixedly connected to the lower end of the tool stem, and the tool head is in an umbrella-shaped structure and can be opened and closed;

[0021] The tool head comprises a blade group 2 and a connecting rod 3, wherein the blade group 2 is arranged around the support rod 1, and each blade of the blade group 2 is connected to the support rod 1 through the connecting rod 3 thereon;

[0022] The support rod 1 is provided with a handle 4 and a soil-dividing shovel 5. The soil-dividing shovel 5 is arranged above the handle 4. The side wall of the support rod 1 is provided with an opening along its length direction. A circle of the connecting rod 3 is embedded in the opening and can move up and down along the height direction of the opening.

[0023] In this embodiment, the outer wall of the connection between the handle 4 and the soil-dividing shovel 5 corresponding to the support rod 1 is provided with a buckle 6. By rotating around the support rod 1, the handle 4 and the soil-dividing shovel 5 can be clamped in the support rod 1 to prevent the handle 4 and the soil-dividing shovel 5 from shifting. The outer wall of the handle 4 is frosted, and a spring is provided inside the handle 4. The outer wall of the handle 4 is provided with a switch. When the switch is turned on, the handle 4 drives the connecting rod 3 to open the blade group 2 in an umbrella shape. The support rod 1 is a tubular body with an internal opening, and the soil-dividing shovel 5 is a cylindrical rod body. The blade group 2 includes a plurality of identical blades.

[0024] In this embodiment, there are four blades, each of which is in the shape of a petal.

[0025] See also Figure 1 and Figure 2 As shown, the handles 4 are provided with two upper and lower parts. The upper handle 4 rotates and moves downward, driving the push rod inside the support rod 1 to move downward. One end of the push rod is connected to the blade group 2 to open the blade group 2. When the upper handle 4 moves downward to the lower handle 4, it moves downward and threadably connects the upper handle 4 to the lower handle 4, thereby positioning the blade group 2.

[0026] When in use, the height of the contact surface between the connecting rod 3 and the supporting rod 1 is adjusted according to the opening angle, and the connecting rod 3 is installed on the drilling machine. The drill bit rotates to impact the ground or other hard objects. The present invention can be used for various hard soil layers, and it saves time and effort to enter the soil layer until the drilling is completed. After the drilling is completed, the debris left by the drilling is within the range of the blade group 2 and will not scatter everywhere. The present invention has a reasonable structural design, is simple and compact, has high efficiency, and is suitable for popularization and application.

[0027] The basic principles and main features of the present invention are described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected. The scope of protection of the invention shall be defined by the attached claims and their equivalents.
