Technical Field

[0001] This utility model belongs to the field of bucket tooth testing technology, and in particular relates to a device for testing the wear of excavator bucket teeth. Background Technology

[0002] Excavator bucket teeth are an important component of excavators, similar to human teeth. They are also wear parts, consisting of a tooth base and tooth tips connected by a pin.

[0003] Utility model patent CN216525292U discloses a high-precision bucket tooth friction and wear testing device, including a hollow base, an electric motor fixed inside the hollow base, a rotating retaining shaft fixed at the upper end of the electric motor's rotating shaft, a rubber washer fixed on the lower surface of the hollow base, an electric telescopic rod fixed on the outer side of the hollow base near the lower surface, a connecting crossbar fixed at the upper end of the electric telescopic rod, an angle adjustment structure provided at the lower end of the connecting crossbar away from the electric telescopic rod, and a rotating basin provided on the upper surface of the hollow base. This device can only test one batch of bucket teeth, and the next batch of bucket teeth can only be tested after the previous batch has been tested. This not only increases the testing time, but also makes the process of removing the bucket teeth cumbersome. Therefore, a new excavator bucket tooth wear testing device is proposed.

[0016] like Figures 1 to 4The excavator bucket tooth wear testing device of this utility model, as shown, includes a base plate 1, a controller 2 mounted on the base plate 1, a hemispherical hollow basin 3 fixedly connected to the base plate 1 for holding test materials, a reinforcing bracket 4 fixedly connected to the base plate 1, a first drive motor 5 fixedly mounted on the reinforcing bracket 4, a first rotating shaft 6 connected to the top of the output shaft of the first drive motor 5, a first rotating disk 7 fixedly mounted on the top of the first rotating shaft 6, two second drive motors 8 fixedly mounted on the first rotating disk 7, a second rotating shaft 9 connected to the bottom of the output shaft of the second drive motor 8, a second rotating disk 10 connected to the bottom of the second rotating shaft 9, a distance sensor 11 mounted on the second rotating disk 10, and multiple first electric push rods 12 mounted on the second rotating disk 10. A first connecting rod 13 is connected to the bottom of the telescopic rod of the first electric push rod 12, a connecting top plate 14 is connected to the bottom of the first connecting rod 13, and a first fixing frame 15 is fixedly connected to the connecting top plate 14. Bucket teeth 101 are attached to a top plate 14. A second electric push rod 16 is fixedly installed on the top plate 14. A second connecting rod 17 is connected to the telescopic rod of the second electric push rod 16. A clamping plate 18 is fixedly connected to the second connecting rod 17. A groove is opened on the clamping plate 18. The clamping plate 18 is slidably connected to the first fixed frame 15. The clamping plate 18 is used to fix the bucket teeth 101. Two conveying frames 19 are fixedly connected to the bottom plate 1. Two second fixed frames 20 are fixedly connected to the bottom plate 1. A third drive motor 21 is fixedly installed on the second fixed frame 20. A third rotating shaft 22 is connected to the output shaft of the third drive motor 21. The third rotating shaft 22 is rotatably connected to the conveying frame 19. A first conveyor wheel 23 is rotatably connected to the conveying frame 19. The first conveyor wheel 23 is connected to the third rotating shaft 22. A second conveyor wheel 24 is rotatably connected to the conveying frame 19. A conveyor belt 25 is connected between the first conveyor wheel 23 and the second conveyor wheel 24. The conveyor belt 25 is used to transport the bucket teeth 101.

[0017] The controller 2 is equipped with a first button and a second button.

[0018] The working principle of this utility model is as follows: the distance sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0019] After pouring test materials such as soil, stones, and sand into the hemispherical hollow basin, the bucket teeth are then hung on the first fixed frame. Next, the second electric push rod is controlled to drive the second connecting rod and the clamping plate to move, so that the clamping plate moves to contact the bucket teeth, thereby fixing the bucket teeth.

[0020] Pressing the first button controls the first drive motor to work for a certain period of time and then stop. The first drive motor drives the first rotating shaft, the first rotating disk, the clamping plate, and the bucket teeth to rotate above the hemispherical hollow basin. Then, pressing the second button controls the first electric push rod to drive the first connecting rod, the connecting top plate, the first fixed frame, the second electric push rod, the second connecting rod, the clamping plate, and the bucket teeth to descend, so that the bucket teeth come into contact with the test material. When the distance between the distance sensor and the connecting top plate reaches the first threshold preset by the distance sensor, the first electric push rod stops working, and at the same time, the second drive motor is controlled to work. The second drive motor drives the second rotating shaft, the second rotating disk, the connecting top plate, and the bucket teeth to rotate, so that the bucket teeth can conduct friction and impact tests with different test materials such as soil, stones, and sand, simulating different digging environments.

[0021] After the test is completed, press the second button again to stop the second drive motor. At the same time, control the first electric push rod to drive the first connecting rod, connecting top plate, first fixed frame, second electric push rod, second connecting rod, clamping plate and bucket teeth to rise. When the distance between the distance sensor and the connecting top plate reaches the second threshold preset by the distance sensor, control the first electric push rod to stop. At the same time, control the first drive motor to work for a certain period of time and then stop. The first drive motor drives the first rotating shaft, first rotating disc, clamping plate and bucket teeth to rotate between the two transport frames.

[0022] The second electric push rod is controlled to drive the second connecting rod and the clamping plate to move in the opposite direction, so that the clamping plate moves away from the bucket teeth, thereby engaging the fixed state of the bucket teeth. Then, the third drive motor is controlled to drive the third rotating shaft, the first conveyor wheel, the second conveyor wheel and the conveyor belt to rotate. The operator removes the bucket teeth from the first fixed frame for observation, and then places qualified and unqualified products on two separate conveyor belts. The conveyor belts will transport different bucket teeth, thereby classifying the tested bucket teeth and improving the testing efficiency. During the bucket teeth testing, another batch of bucket teeth can be placed on the unused first fixed frame, thereby reducing the bucket teeth testing time.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
