Description

Technical Field

[0001] This utility model relates to the technical field of glass transfer devices, and in particular to a grinding device for workpieces of mini excavator bucket teeth. Background Technology

[0002] Bucket teeth are an important component of excavators, mainly installed on the bucket to assist in digging operations. One of their main functions is to excavate soil, stones, and ores. Bucket teeth are usually made of high-strength steel and have an irregular shape. Because the bucket experiences significant wear during operation, the bucket teeth provide a degree of protection for the bucket.

[0003] The existing mini excavator bucket tooth workpiece grinding device has some drawbacks in use. The use of water for cooling and reducing debris splashing during grinding can easily lead to water waste. To solve the above problems, we propose a mini excavator bucket tooth workpiece grinding device. Summary of the Invention

[0004] The main purpose of this utility model is to provide a grinding device for the bucket teeth of a mini excavator, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A grinding device for bucket teeth of a mini excavator includes a worktable and bucket teeth. An electric push rod is provided at the upper end of the worktable, and a fixing ring is provided on the outer side of the electric push rod.

[0013] Compared with the prior art, this utility model has the following beneficial effects: In use, the electric actuator is activated to transport the bucket tooth workpiece backward. The bucket tooth workpiece is clamped and fixed by a clamp. As the bucket tooth workpiece moves backward, the second slider slides up and down within the third groove. The second slider is fixedly connected to the second grinding wheel. The second motor is activated to drive the second grinding wheel to grind the bucket tooth workpiece. Simultaneously, the third motor is activated to drive the first grinding wheel to grind the bucket tooth workpiece. When the bucket tooth workpiece is being ground... Meanwhile, the water in the first water tank is cooled by the shower head, which sends a command to the first motor to rotate the threaded rod in both directions. Through the principle of the screw, the scraper can slide back and forth, sweeping the wastewater from grinding and cooling to the ramp. The ramp then concentrates the wastewater into the second water tank, where it is filtered through a filter screen. The filtered water is then pumped out by a water pump and transported forward through a water pipe to clean the debris from the ground bucket teeth. This achieves the secondary use of wastewater and saves water resources. Attached Figure Description

By outputting a command to the third motor 27, the first grinding wheel 17 can be rotated to grind the lower end of the bucket tooth 2. The outer shell 1 acts as a sound insulation for the second motor 22, and the outer shell 2 acts as a noise reduction for the third motor 27.

[0031] In this embodiment, a first slider 19 is fixedly connected to the rear end of the outer shell 1, a first groove 20 is provided on one side of the connecting shell 5, the first slider 19 is slidably connected to the inner side of the first groove 20, a second groove 21 is provided on both sides of the connecting shell 5, and a second grinding wheel 18 is slidably connected to the inner side of the second groove 21.

[0033] In this embodiment, two sets of gears 23 are rotatably connected to the outer side of the second grinding wheel 18. The two sets of gears 23 are symmetrical to each other. A second slider 24 is movably connected to the opposite side of each set of gears 23. Two sets of toothed plates 26 are fixedly connected to the inner side of the connecting shell 5. A third slide groove 25 is opened on the opposite side of each set of toothed plates 26. The second slider 24 is slidably connected to the inner side of the third slide groove 25.

[0034] Specifically, a gear 23 is rotatably connected to the outer side of the second grinding wheel 18. The two sets of gears 23 are symmetrical to each other. A second slider 24 is movably connected to the opposite side of each set of gears 23. Two sets of toothed plates 26 are fixedly connected to the inner side of the connecting shell 5, which can make the gears 23 mesh with the third slide groove 25. A third slide groove 25 is opened on the opposite side of each set of toothed plates 26. The second slider 24 is slidably connected to the inner side of the third slide groove 25, driving the second slider 24 to slide inside the third slide groove 25.

[0035] In this embodiment, the rear end of the connecting shell 5 is provided with an opening, and the rear end of the workbench 1 is fixedly connected to a ramp 12, the lower end of the ramp 12 being connected to the water storage tank 9.

[0036] Specifically, the rear end of the connecting shell 5 is provided with an opening, and the rear end of the workbench 1 is fixedly connected to a ramp 12. The lower end of the ramp 12 is connected to the second water storage tank 9.

[0037] It should be noted that this utility model is a grinding device for bucket teeth of a mini excavator. In use, the bucket teeth 2 are placed inside the tiger clamp 6 for fixation. By outputting a command to the electric push rod 3, the tiger clamp 6 can move the bucket teeth 2 back and forth. At the same time, the backward movement of the bucket teeth 2 can cause the second slider 24 to slide up and down in the third slide groove 25. The second motor 22 and the third motor 27 are started to grind the bucket teeth 2. Meanwhile, the water in the first water tank 7 falls through the tiger clamp 6 for cooling. By outputting a command to the first motor 13, the scraper 16 can push the wastewater from the front end of the connecting shell 5 to the opening at the rear end of the connecting shell 5 through the lead screw principle. Then, the wastewater is collected into the second water tank 9 through the ramp 12. The wastewater is then filtered through the filter screen 28 in the second water tank 9. The water pump 10 is started to transport the cleaned water through the water pipe 11. Finally, the surface of the ground bucket teeth 2 is cleaned of debris, thereby achieving the secondary utilization of wastewater.
