For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of dredger bucket tooth assembly, comprise the bucket tooth and toothholder that are connected by pin, described bucket tooth afterbody is provided with bucket tooth mounting groove, described toothholder end is toothholder installation portion, it is characterized in that: described pin comprises pin main body and is rotatably connected on the rotating dog at described pin main body two ends, be connected by helical spring between described rotating dog with pin main body, described pin main body excircle is axially arranged with some convex keys, the excircle of described rotating dog is provided with grab, described grab and some described convex keys are all not on the same line, described toothholder installation portion is provided with the through hole matched with described pin main body and the convex keyway matched with described convex key, two opposite flanks of described bucket tooth mounting groove are provided with the installing hole matched with described pin main body and the second convex keyway matched with described convex key, the lateral surface of bucket tooth mounting groove is also provided with to match with described grab and draw-in groove.
Further, the excircle of described pin main body is axially arranged with four convex keys, four described convex keys are uniformly distributed, and described convex keyway and the second convex keyway all have four, and circumference is uniformly distributed.
Further, the two ends of described pin main body are provided with connecting rod, and the end of described connecting rod is axially arranged with the shaft shoulder, and described rotating dog is arranged on described connecting rod, rotating dog is provided with the shaft shoulder groove for holding the described shaft shoulder, and rotating dog can move vertically relative to described connecting rod.
Further, described grab can pass described convex keyway and the second convex keyway.
Further, also anti-skid rubber cushion is provided with between described toothholder installation portion and described bucket tooth mounting groove.
The advantage that the present invention has and beneficial effect are: pin main body is provided with convex key, toothholder installation portion and bucket tooth mounting groove are respectively equipped with the convex keyway and the second convex keyway that match with convex key, convex key effectively can prevent the rotation between toothholder installation portion and bucket tooth mounting groove, makes to connect between toothholder installation portion and bucket tooth mounting groove more fastening; Pin main body both sides connect rotating dog by helical spring, rotating dog is provided with grab, and grab not with convex key point-blank, therefore, grab and one of them convex key mapping can be made in the installation of the enterprising marketing of straight line by rotating rotating dog, and after installing, under helical spring axial and circumferential active force, in the draw-in groove that grab is stuck on bucket tooth, realize the auto-lock function of pin, in case shotpin comes off; In order to ensure stable connection between toothholder installation portion and bucket tooth mounting groove, be also provided with anti-skid rubber cushion.Dredger bucket tooth assembly of the present invention, toothholder and bucket tooth can be made to assemble fastening, and disassembling operations is easy.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As Figure 1-Figure 5, the invention provides a kind of dredger bucket tooth assembly, comprise the bucket tooth 2 and toothholder 1 that are connected by pin, bucket tooth 2 afterbody is provided with bucket tooth mounting groove 21, and toothholder 1 end is toothholder installation portion 11, and toothholder installation portion 11 and bucket tooth mounting groove 21 assemble.
Pin comprises pin main body 31 and is rotatably connected on the rotating dog 32 at pin main body two ends, is connected between rotating dog 32 with pin main body 31 by helical spring 33.Pin main body 31 excircle is axially arranged with four convex keys, 34, four convex keys 34 be evenly distributed in pin main body 31.The excircle of rotating dog 32 is provided with grab 35, and grab 35 and four convex keys 34 are all not on the same line.The two ends of pin main body 31 are installed with connecting rod 36, the end of connecting rod 36 is circumferentially with the shaft shoulder 37, rotating dog 32 is arranged on connecting rod 36, and rotating dog 32 is provided with the shaft shoulder groove 38 for holding the shaft shoulder 37, makes rotating dog 32 can moving axially along pin main body 31.
Toothholder installation portion 11 is provided with the through hole 12 matched with pin main body 31 and the convex keyway 13 matched with convex key 34.Two opposite flanks of bucket tooth mounting groove 21 are provided with the installing hole 22 matched with pin main body 31 and the second convex keyway 23 matched with convex key 34, and convex keyway 13 and the second convex keyway 23 all have four.The lateral surface of bucket tooth mounting groove 21 is also provided with to match with grab 35 and draw-in groove 24.
Grab 35 can pass convex keyway 13 and the second convex keyway 23.
In order to prevent toothholder installation portion 11 and bucket tooth mounting groove 21 from sliding further, between toothholder installation portion 11 and bucket tooth mounting groove 21, be also provided with anti-skid rubber cushion 4.
The course of work: toothholder installation portion 11 is inserted in bucket tooth mounting groove 21, through hole 12 is made to want to overlap with installing hole 22, convex keyway 13 and the second convex keyway 23 coincide, rotate rotating dog 32, grab 35 and one of them convex key 34 are located on the same line, then rotating dog 32 and pin main body 31 are installed into installing hole 22 successively, in through hole 12 and installing hole 22, after rotating dog 32 stretches out the installing hole 22 of offside, under the circumferential active force of torsional spring 33, rotating dog 32 is kept in the center, grab 35 is just made to stick in draw-in groove 24, then the grab 35 on the rotating dog 32 of the other end is sticked in draw-in groove 24, this completes whole installation process, because convex key 34 is stuck in the convex keyway 13 of toothholder installation portion 11 and the second convex keyway 23 of bucket tooth mounting groove 21 simultaneously, thus effectively prevent the rotation between toothholder installation portion 11 and bucket tooth mounting groove 21, and under the active force of helical spring 33, pin can be made to be self-locking in junction, not easily landing.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
