Description

Technical Field

[0001] This application relates to the field of excavator technology, and more particularly to an excavator head and an excavator. Background Technology

[0002] Most existing excavator shovels adopt a simple one-piece straight or arc-shaped structure. When digging soil, this structure is prone to bending of the shovel surface due to uneven force distribution, which affects the digging depth and efficiency. At the same time, the shoulder design of the shovel head often neglects the comfort of the foot, and the connection is prone to concentrated reaction force, which affects the user experience. Utility Model Content

[0003] The problem this application aims to solve is that most existing excavator blades adopt a simple one-piece straight or arc-shaped structure, which easily leads to the blade bending under stress when excavating soil due to uneven force distribution.

[0004] To solve the above-mentioned technical problems, this application provides a shovel head, including an integrally formed trouser leg and a shovel face. The trouser leg has a straight cylindrical structure and anti-slip protrusions are arranged in a spiral on its surface. The front view of the shovel face has a shield-shaped structure. The shovel face has symmetrically arranged shoulders at its ends. The surface of the shoulders has anti-slip protrusions. The shovel face has a curved shovel tip.

[0005] Because the shovel head of this application is designed with a curved shovel tip, the resistance when digging soil can be reduced by adjusting the shovel tip structure at the end of the shovel face, thus avoiding shovel face bending and increasing digging depth. This solves the problem that most existing shovel heads adopt a simple one-piece straight plate or arc-shaped structure, which easily leads to shovel face bending due to uneven force distribution when digging soil.

[0012] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0013] This application relates to a shovel head and a digging shovel, such as Figure 1-5 As shown, the shovel head includes an integrally formed trouser leg 1 and a shovel face 3. The trouser leg 1 has a straight cylindrical structure with a spiral surface and outwardly protruding anti-slip protrusions at intervals to enhance stability and anti-slip properties when gripped. The shovel face 3 has a shield-shaped structure when viewed from the front, providing sufficient strength and stability. The end of the shovel face 3 has symmetrically arranged outwardly folded shoulders 2, and the surface of the shoulders 2 also has outwardly protruding anti-slip protrusions to improve stability and safety when stepping on the ground. The shovel face 3 has a shovel tip 4, which is located at the tip of the shovel face 3. In order to reduce the resistance encountered when digging the soil, the shovel tip 4 is curved along with the shovel face 3. The angle between the shovel face 3 and the X-axis in the top view is 15-35°. The closer the shovel face 3 is to the trouser leg 1, the smaller the angle. This design allows the shovel face 3 to cut into the soil more smoothly during digging, reducing resistance. The angle between the shovel tip 4 and the Y-axis in the side view is 35-40°. This angle design helps the shovel tip 4 to dig deeper into the soil.

[0014] To improve the comfort of stepping on the footrest 2 and avoid a large and concentrated reverse force on the foot at the connection between the footrest 2 and the shovel wing, the angle between the footrest 2 and the shovel wing is 95-100°.

[0015] The shovel tip 4 protrudes outwards, and the included angle of its tip is 130-135°. This design helps the shovel tip 4 penetrate the soil more effectively.

[0016] The length ratio between the trouser leg 1 and the shovel head is 1:1. This ratio design makes it easy to hold the trouser leg 1 and allows the shovel head to fully apply the force during digging.

[0017] To ensure the overall strength of the shovel head, one side of the shovel head is made up of three arcs from the shoulder 2 to the tip. The ratio of the radii between the arcs is 1:12.62:2.13, and the ratio of the central angles between the arcs is 5.56:1:5.42. This design allows the shovel head to distribute pressure more evenly when under stress, thus preventing bending.

[0018] The excavating shovel includes a shovel head, a shovel handle, and a shovel rod. The shovel head and shovel handle are connected to the shovel rod by fasteners, which can be screws, nails, or rivets, to ensure a firm connection and easy disassembly and maintenance.

[0019] When using the shovel, the user first holds the trouser leg 1 of the shovel head. Because trouser leg 1 has a straight cylindrical structure and a spirally arranged anti-slip protrusion on its surface, it provides a good grip and anti-slip performance, ensuring the user can firmly control the shovel head during use. When greater digging force is required, the user can place their foot on the shoulder 2 of the shovel face 3. The shoulder 2 surface is also equipped with anti-slip protrusions, effectively preventing the foot from slipping. At the same time, the angle between the shoulder 2 and the shovel wings is designed to be 95-100°, making foot placement more comfortable and reducing the impact of reaction force on the foot. The user then inserts the shovel head into the soil. The shovel face 3 has an angle of 15-35° relative to the X-axis in the top view, and the shovel tip 4 is also curved along with the shovel face 3. Therefore, the shovel head can cut into the soil more smoothly and reduce digging resistance. At the same time, the shovel tip 4 has an angle of 35-40° relative to the Y-axis in the side view, which helps the shovel tip 4 to dig deeper into the soil. During the digging process, the user can apply digging force by holding the trouser leg 1 and stepping on the shoulder 2. Since the length ratio between the trouser leg 1 and the shovel head is 1:1, it is easy for the user to apply sufficient digging force. At the same time, the overall strength of the shovel head is guaranteed, and it will not bend or deform even when a large digging force is applied.
