Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric pick technology, specifically relating to a high-efficiency brushless motor electric pick. Background Technology
[0002] An electric pick is a double-insulated handheld power tool powered by a single-phase series motor. It is safe, reliable, efficient, and easy to operate, and is widely used in pipeline laying, machinery installation, water supply and drainage facility construction, interior decoration, port facility construction, and other construction projects.
[0003] Electric hammers commonly used have cutting tools in the form of cones and shovels. The shovel-shaped cutting tool has a straight end. When in use, the part that contacts the target is in a straight line, resulting in a relatively large force-bearing area. When hammering hard concrete, it requires multiple hammer blows to break through, which affects efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency brushless motor electric pick, which makes it easier for the end of the shovel-shaped head to impact and penetrate into the target location, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency brushless motor electric pick, comprising an electric pick body and a pick drill bit, wherein the pick drill bit is installed at one end of the electric pick body; The drill bit includes a drill rod and a drill bit, the drill bit being fixedly connected to one end of the drill rod, and one end of the drill rod being provided with a shovel-shaped head; One end of the shovel-shaped head is provided with a notch, and a secondary shovel head is provided inside the notch.
[0006] Furthermore, the material of the drill rod is silicon-manganese alloy steel, and the drill bit, shovel-shaped head, and auxiliary shovel head are an integral structure, with the drill bit being made of brazed cemented carbide.
[0007] Furthermore, there are several notches, and these notches are equidistantly distributed along the length direction of the shovel-shaped head.
[0008] Furthermore, the notch is a trapezoidal structure that is narrower at the bottom and wider at the top.
[0009] Furthermore, the length of the secondary shovel head is equal both vertically.
[0010] Furthermore, the length of the secondary shovel head is equal to the length of the top of the notch.
[0011] Furthermore, both the bottom end of the shovel-shaped head and the bottom end of the auxiliary shovel head are provided with a chamfer.
[0012] Compared with the prior art, the beneficial effects of this utility model are: because the end of the shovel-shaped head is provided with a notch, the contact area between the end and the target point is reduced, and the pressure is greater when hammering. Therefore, it is easier for the end of the shovel-shaped head to impact into the target point. After the shovel-shaped head enters, the secondary shovel head hammers the remaining points, which makes it easier to hammer open the target point and improve the hammering efficiency.

[0014] The attached diagram lists the components represented by each number as follows: 1. Electric pick body; 2. Picking rod; 21. Pick rod; 22. Pick bit; 23. Shovel head; 24. Notch; 25. Secondary shovel head. Detailed Implementation
[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0016] like Figure 1-4 As shown, a high-efficiency brushless motor electric pick includes an electric pick body 1 and a pick drill bit 2. The pick drill bit 2 is installed at one end of the electric pick body 1. The pick drill bit 2 includes a drill rod 21 and a drill bit 22. The drill bit 22 is fixedly connected to one end of the drill rod 21. One end of the drill rod 21 is provided with a shovel-shaped head 23. One end of the shovel-shaped head 23 is provided with a notch 24. A secondary shovel head 25 is provided inside the notch 24.
[0017] According to the above structure, when in use, the end of the shovel-shaped head 23 has a notch 24, so the contact area between its end and the target point is reduced, and the pressure is greater when hammering. Therefore, it is easier for the end of the shovel-shaped head 23 to impact into the target point. After the shovel-shaped head 23 enters, the secondary shovel head 25 hammers the remaining points, which makes it easier to hammer open the target point and improve the hammering efficiency.
[0018] like Figure 3 and 4As shown, the material of the drill rod 21 is silicon manganese alloy steel, and the drill bit 22, the shovel-shaped head 23 and the auxiliary shovel head 25 are an integral structure. The material of the drill bit 22 is brazed cemented carbide.
[0019] Based on the above structure, the end of the entire drill bit 2 is in direct contact with the target object, so a brazing carbide with higher hardness and wear resistance is used, while the drill rod 21 is only used as a force transmission component, so conventional silicon-manganese alloy steel is used.
[0020] like Figure 3 and 4 As shown, there are several notches 24, and the notches 24 are equidistantly distributed along the length direction of the shovel-shaped head 23.
[0021] According to the above structure, the arrangement of several notches 24 can form a notch at the end of the shovel-shaped head 23, thereby reducing its contact area with the target object and increasing the pressure during hammering.
[0022] like Figure 3 and 4 As shown, the notch 24 is a trapezoidal structure that is narrow at the bottom and wide at the top. The length of the secondary shovel head 25 is equal at the top and bottom, and the length of the secondary shovel head 25 is equal to the length of the top of the notch 24.
[0023] According to the above structure, the projections of the end sub-shovel head 25 and the notch 24 in the vertical direction overlap at the end of the shovel head 23, thereby avoiding the leakage of hammering residue.
[0024] like Figure 3 and 4 As shown, both the bottom end of the shovel head 23 and the bottom end of the auxiliary shovel head 25 are provided with chamfers.
[0025] Based on the above structure, the ends of the shovel head 23 and the secondary shovel head 25 are made sharper, thereby improving the hammering efficiency.
[0026] The working principle of this utility model is as follows: During use, the end of the shovel-shaped head 23 has a notch 24, thus reducing the contact area between its end and the target point. This results in greater pressure during hammering, making it easier for the end of the shovel-shaped head 23 to impact and penetrate the target point. After the shovel-shaped head 23 enters, the auxiliary shovel head 25 hammers the remaining points, facilitating the hammering of the target point and improving hammering efficiency. The entire end of the drill bit 2 directly contacts the target object; therefore, a harder and more wear-resistant brazed carbide is used. The drill rod 2... Since it is used as a force transmission component, it is made of conventional silicon-manganese alloy steel. The notches 24 can form notches at the end of the shovel head 23, thereby reducing its contact area with the target object and increasing the pressure during hammering. The projection of the secondary shovel head 25 at the end of the shovel head 23 and the notches 24 overlaps in the vertical direction, thus avoiding hammering leakage. The bottom ends of the shovel head 23 and the secondary shovel head 25 are both provided with chamfers, making the ends of the shovel head 23 and the secondary shovel head 25 sharper and improving hammering efficiency.
[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
