Description

Technical Field

[0001] This patent relates to the field of excavator buckets, and more specifically to a swingable excavator bucket. Background Art

[0002] Excavators are very common construction machinery, which can greatly improve the efficiency of the project and reduce the use of manpower. The bucket is an essential and important part of the excavator. The traditional bucket can only be driven by the hydraulic arm of the excavator, that is, the simplest way is to use the connection point between the bucket and the hydraulic arm as the center of the circle to perform up and down flipping movements, so as to realize the excavation and transportation of soil and other materials. With the continuous development of excavators, in order to be suitable for use in different occasions, the swingable excavator bucket has appeared on the market;

[0003] However, the existing technology of the swingable external bucket still has some shortcomings. For example, the traditional bucket that uses a hydraulic cylinder to drive the bucket to swing to the left and right directions does not have lubrication protection on the hydraulic cylinder and the bucket, which is prone to hard friction and damage to the swing shaft. Therefore, the existing technology needs to be improved. Utility Model Content

In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is a schematic diagram of the structure of the patent, a swingable excavator bucket, comprising a bucket 1 and a bearing platform 6, wherein the lower end of the bearing platform 6 is equipped with two matching pieces 5, and the upper end of the bucket 1 is equipped with a matching plate 2;

[0025] The middle section of the upper end of the matching plate 2 is equipped with two connecting frames 3, and a hinge sleeve is installed between the two matching pieces 5;

[0026] A rotating shaft 7 is installed between the two connecting frames 3, and an articulated sleeve is hinged on the outside of the rotating shaft 7, so as to realize the connection between the bucket 1 and the bearing platform 6. The matching relationship and specific structure between the two are the same as those in the patent number CN202220765282.4, and the driving arm of the excavator is connected through the bearing platform 6;

[0027] A deflection mechanism 4 is installed on the lower side between the two matching pieces 5, and the deflection mechanism 4 includes a deflection rod 41 installed between the two matching pieces 5;

[0028] The lower ends of the inner walls on both sides of the two matching pieces 5 are equipped with a yaw shaft 44, and the two ends of the yaw rod 41 are installed with lubrication seats 43. The lubrication seats 43 are hinged to the outside of the yaw shaft 44. The yaw shaft 4 is set and fixed on the inner wall of the matching piece 5. The two ends of the yaw rod 41 are sleeved on the yaw shaft 4 through the lubrication seats 43, and then the yaw is driven by the extension and contraction of the hydraulic cylinder.

[0029] The deflection rod 41 includes an inner support rod 411 and an outer rod 413. The outer rod 413 is sleeved on the outside of the inner support rod 411. The outer wall of the inner support rod 411 is provided with a support groove 11. The inner wall of the outer rod 413 is installed with a support block 10. The support block 10 is arranged in the support groove 11. Through the cooperation of the support block 10 and the support groove 11, the outer rod 413 is sleeved on the outside of the inner support rod 411. Both are made of stainless steel. Through the setting of the two rods in the inner sleeve, the weight can be reduced and the strength can be improved.

[0030] The outer wall of the outer sleeve rod 413 is provided with a heat dissipation groove 412 .

[0031] The lubrication seat 43 includes two relatively arranged shaft cylinders a 431 and shaft cylinder b 432. The inner walls of the shaft cylinder a 431 and the shaft cylinder b 432 are evenly provided with a rotation cavity 13. The interior of the rotation cavity 13 is installed with a ball 12. The ball 12 is closely arranged with the yaw shaft 44. By the rotation of the ball 12 in the rotation cavity 13 and the close fit of the ball 12 with the yaw shaft 44, the lubrication seat 43 is prevented from directly contacting with the yaw shaft.

[0032] The outer walls of both sides of the shaft cylinder a 431 and the shaft cylinder b 432 are both installed with fixing plates 433, and the two fixing plates 433 are connected by bolts.

[0033] An axle seat 9 is assembled on one side of the upper end of the matching plate 2, a hydraulic cylinder 8 is hinged inside the axle seat 9, a shaft sleeve 42 is sleeved on the outer middle section of the yaw rod 41, and the output end of the hydraulic cylinder 8 is connected to the shaft sleeve 42, and the yaw can be driven by the extension and contraction of the hydraulic cylinder 8.

[0034] Working process and principle: When in use, the bucket 1 is installed on the hydraulic arm of the excavator through the load-bearing platform. The bucket 1 can realize the most basic up and down digging actions. When some special engineering occasions cannot directly perform up and down digging actions, the hydraulic cylinder 8 can be started. When the piston end of the hydraulic cylinder 8 extends forward, the bucket 1 can be driven to swing toward the direction of the hydraulic cylinder 8 through the swing mechanism 4, and vice versa.
