Description

Technical Field

[0001] The utility model relates to the technical field of excavator accessories, in particular to an excavator bucket tooth with a diversion groove. Background Art

[0002] Excavator bucket teeth are important components of the excavator and are wearing parts. They are combined bucket teeth consisting of a tooth seat and a tooth tip, which are connected by a pin shaft. In a complete excavation process, the force conditions are different in different working stages. When the tooth tip first contacts the material surface, due to the faster speed, the tip of the bucket tooth is subjected to greater pressure, so the bucket tooth is required to have strong hardness and pressure relief effect.

[0003] In order to reduce the resistance of the bucket teeth, the existing excavator bucket teeth have diversion grooves on both sides. The purpose of the diversion grooves on the bucket teeth is to allow the soil or stones to be discharged from both sides when the bucket teeth are digging, thereby reducing the resistance of the bucket teeth. The setting of the protective block effectively prevents hard objects from damaging the bucket teeth. The utility model has a simple structure and a long service life.

[0004] However, during the actual use of the above-mentioned equipment, a small amount of excavated soil will adhere to the inner wall surface of the diverter trough after entering the diverter trough, and will continue to accumulate thicker over time, thereby gradually weakening the diversion effect of the diverter trough. After filling the diverter trough, it may even cause the diverter trough to lose its function, thereby causing the pressure on the bucket teeth to fail to be sufficiently reduced, affecting the service life of the bucket teeth. In view of this, we propose an excavator bucket tooth with a diverter trough. Utility Model Content

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: an excavator bucket tooth with a diverter groove, comprising a bucket tooth body 1, a diverter groove 2 is opened on the upper surface of the bucket tooth body 1, a pushing component is arranged inside the diverter groove 2, the diverter groove 2 can make the excavated material be diverted to the two sides of the triangular protrusion, reducing the resistance of the bucket tooth, and the setting of the protective block effectively prevents hard objects from damaging the bucket tooth.

[0027] The pushing component includes: a triangular block 301, a movable groove 304 and a special-shaped block 309. The triangular block 301 is fixedly installed on the inner bottom surface of the diversion groove 2. The triangular block 301 is set to form a plowing effect. When the bucket teeth cut the material, the bucket teeth and the material move relative to each other. The triangular block 301 generates a large positive extrusion pressure on the surface of the material, thereby generating a large friction between the working surface of the bucket teeth and the material, which can improve the excavation cutting speed. In addition, by setting the opening direction of the triangular block 301 to increase upward, the material is broken layer by layer through the trapezoidal concave groove. A pushing groove 302 is opened on the upper surface of the triangular block 301, and a through groove 303 is opened at the left end of the bottom surface of the pushing groove 302. The through groove 303 makes the left bottom surface of the pushing groove 302 have an open structure.

[0028] The movable groove 304 is provided on a side surface of the pushing groove 302 near the center of the bucket tooth body 1, and a limiting groove 305 is provided on the right inner wall surface of the movable groove 304. A pushing spring 306 is fixedly installed on the right inner wall surface of the limiting groove 305, and a connecting rod 307 is fixedly installed on the left end of the pushing spring 306. The outer wall of the connecting rod 307 fits the inner wall of the limiting groove 305, and a sealing block 308 is fixedly installed on the left end of the connecting rod 307. The outer wall of the sealing block 308 fits the inner wall of the movable groove 304. In the initial state, the sealing block 308 seals the left end of the movable groove 304, so that the left side surface of the triangular block 301 is complete. The plane is set, the special-shaped block 309 is set inside the pushing groove 302, the outer wall of the special-shaped block 309 is in contact with the inner wall of the moving groove 304, a trapezoidal inner groove 310 is provided on the left surface of the special-shaped block 309, the outer wall of the special-shaped block 309 is fixedly connected with the outer wall of the sealing block 308, the set trapezoidal inner groove 310 can increase the friction area between the special-shaped block 309 and the material, the upper plate part of the special-shaped block 309 is a triangular column structure, and a rectangular block is arranged at the bottom end, which can perform linear motion in the left and right directions inside the pushing groove 302 and the through groove 303, and the bottom surfaces of the pushing groove 302 and the through groove 303 are sealed to prevent soil from entering.

[0029] When the special-shaped block 309 moves, it can drive the sealing block 308 and the connecting rod 307 to move synchronously. When the bucket tooth body 1 is working, the material will push the special-shaped block 309, so that the special-shaped block 309 moves to the right, and squeezes the push spring 306 through the sealing block 308 and the connecting rod 307, so that the push spring 306 is compressed to generate elastic potential energy. When the material is transported, the sealing block 308, the connecting rod 307 and the special-shaped block 309 will be reset under the action of the elastic potential energy of the push spring 306, so that the special-shaped block 309 can push the entire piece of soil attached to the triangular block 301 to prevent the soil block from being attached to the triangular block 301 as a whole, causing the triangular block 301 to lose its original effect. The special-shaped block 309 and the sealing block 308 can seal the inside of the moving groove 304 and the limiting groove 305 to prevent soil from entering the inside and causing the pushing component to fail to work.

[0030] A rectangular groove 401 is provided on the inner bottom surface of the diversion groove 2, and a limiting ring plate 402 is fixedly installed inside the rectangular groove 401. A return spring 403 is fixedly installed on the inner bottom surface of the rectangular groove 401, and a top block 404 is fixedly installed on the upper end of the return spring 403. The outer wall of the top block 404 fits with the inner wall of the rectangular groove 401. When the bucket tooth body 1 is excavating, the material will squeeze the top block 404 and compress the return spring 403 to generate elastic potential energy. After the material enters the bucket, the top block 404 will move upward and reset under the action of the elastic potential energy of the return spring 403, and clean the gap between the two triangular blocks 301 to prevent the soil from filling the gap between the two triangular blocks 301, causing the triangular block 301 to lose its original effect.

[0031] In the utility model, when in use, when the bucket tooth body 1 is digging, the diverter groove 2 will divert the material. In the process of digging the material, the triangular block 301 is set to form a plowing effect, which generates a large friction between the bucket tooth working surface and the material, thereby improving the cutting speed of digging, and breaking the material layer by layer to prevent the material from blocking and affecting the diversion effect. The material will push and squeeze the special-shaped block 309 and the top block 404, so that the special-shaped block 309 and the top block 404 leave their original positions, and compress the push spring 306 and the return spring 403 to generate elastic potential energy. After the digging is completed, the special-shaped block 309 and the top block 404 will be reset under the action of the elastic potential energy of the push spring 306 and the return spring 403, and push the surface of the triangular block 301 and the gap between the two triangular blocks 301, so as to prevent the soil from being continuously squeezed, resulting in lumps adhering to the surface of the triangular block 301 and between the two triangular blocks 301, causing the triangular block 301 to lose its original function.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
