[0025] Please refer to Figure 1-2 , the present utility model provides a technical solution: including a support plate 1, a test box 2 is fixedly connected to the lower front side of the support plate 1, a plurality of material receiving grooves are opened at the top of the test box 2, a movable structure 3 is fixedly connected to the upper front side of the support plate 1, a driving structure 4 is fixedly connected to the top of the movable structure 3, and a plurality of fixing structures 5 are fixedly connected to the bottom of the movable structure 3.

[0026] Please refer to Figure 3-4, the movable structure 3 includes a mounting plate 31. The rear side of the mounting plate 31 is fixedly connected to the upper part of the front side of the support plate 1. Circular movable holes one penetrating through to the bottom are provided on both the left and right sides of the top of the mounting plate 31. A rectangular movable hole is provided at the middle position of the top of the mounting plate 31. A guide rod 32 is movably connected to the inner wall of the circular movable hole one, and a connecting plate 33 is movably connected to the inner wall of the rectangular movable hole. An oval sleeve 34 is fixedly connected to the top of the connecting plate 33. A fixing plate 35 is fixedly connected to the bottoms of the guide rod 32 and the oval sleeve 34. The driving structure 4 includes a mounting block 41. The bottom of the mounting block 41 is fixedly connected to the top of the mounting plate 31. A motor housing 42 is fixedly connected to the top of the mounting block 41. A driving motor 43 is fixedly connected to the inner wall of the motor housing 42. A circular movable hole two penetrating through to the outside is provided at the rear side of the inner wall of the motor housing 42. The output end of the driving motor 43 is movably connected to the inner wall of the circular movable hole two. A gear one 44 is fixedly connected to the output end of the driving motor 43. A gear two 45 is meshed with the outer wall of the gear one 44. A circular movable hole three penetrating through to the rear side is provided at the front side of the mounting block 41. A rotating rod 46 is fixedly connected to the front end of the gear two 45. The outer wall of the rotating rod 46 is movably connected to the inner wall of the circular movable hole three. A turntable 47 is fixedly connected to the front end of the rotating rod 46. A fixing rod 48 is fixedly connected to the front end of the turntable 47 away from the center point. The outer wall of the fixing rod 48 is movably connected to the inner wall of the oval sleeve 34;

[0027] First, fill the inside of the test box 2 with abrasive, then install the bucket tooth on the fixing structure 5. By starting the driving motor 43, the gear one 44 is driven to rotate. The movement of the gear one 44 further causes the gear two 45 to rotate, driving the rotating rod 46 to rotate on the inner wall of the circular movable hole three. Eventually, the turntable 47 rotates. The rotation of the turntable 47 drives the fixing rod 48 to reciprocate in the oval sleeve 34. At the same time, the sliding of the connecting plate 33 on the inner wall of the rectangular movable hole and the sliding of the guide rod 32 on the inner wall of the circular movable hole one cause the oval sleeve 34 to drive the connecting plate 33 to move up and down when the fixing rod 48 rotates on the inner wall of the oval sleeve 34. The reciprocating movement of the connecting plate 33 drives the oval sleeve 34 and the fixing structure 5 to move accordingly, so as to achieve the effect of detecting the wear of the bucket tooth.

[0028] Please refer to Figure 5 , the fixing structure 5 includes an extension block 51. An extension block 52 is fixedly connected to the bottom of the extension block 51. Mounting grooves 53 are provided on both the front and rear sides of the bottom of the extension block 52.

Plug rods 57 are fixedly connected to the sides of the two movable sleeves 56 away from each other;

[0029] By squeezing the two movable sleeves 56 inward, the movable sleeves 56 then slide on the outer wall of the slide bar 54 and compress the spring 55. Next, align the two inserting rods 57 with the inner inserting holes of the bucket tooth. After releasing the movable sleeves 56, the elastic force of the spring 55 will push the movable sleeves 56, prompting the two inserting rods 57 to firmly insert into the inserting holes of the bucket tooth, realizing the fixation of the bucket tooth.

[0030] Working principle:

[0031] First, fill the inside of the test box 2 with abrasives, then install the bucket tooth on the fixing structure 5. By starting the driving motor 43, the first gear 44 is driven to rotate. The movement of the first gear 44 then prompts the second gear 45 to rotate, driving the rotating rod 46 to rotate on the inner wall of the circular movable hole three. Eventually, the rotation of the turntable 47 is caused. The rotation of the turntable 47 drives the fixing rod 48 to reciprocate within the elliptical sleeve 34. At the same time, the sliding of the connecting plate 33 on the inner wall of the rectangular movable hole and the sliding of the guiding rod 32 on the inner wall of the circular movable hole one cause the elliptical sleeve 34 to drive the connecting plate 33 to move up and down when the fixing rod 48 rotates on the inner wall of the elliptical sleeve 34. The reciprocating movement of the connecting plate 33 up and down then drives the elliptical sleeve 34 and the fixing structure 5 to move accordingly, thus achieving the effect of wear detection of the bucket tooth.

[0032] By squeezing the two movable sleeves 56 inward, the movable sleeves 56 then slide on the outer wall of the slide bar 54 and compress the spring 55. Next, align the two inserting rods 57 with the inner inserting holes of the bucket tooth. After releasing the movable sleeves 56, the elastic force of the spring 55 will push the movable sleeves 56, prompting the two inserting rods 57 to firmly insert into the inserting holes of the bucket tooth, realizing the fixation of the bucket tooth.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
