Embodiment 1
A kind of shoveling facility snap ring tooth device, comprises the cutter tooth 10 be attached on shoveling facility, toothholder 20 and snap ring 30; Dismountable cutter tooth 10 passes through snap ring 30 holding on toothholder 20; cutter tooth 10 comprises the land 15 of dredging soil property, the tooth root 111 supported, the tooth wing 12 of protection toothholder and the tooth muscle 18 of reinforcement; land 15 is positioned at cutter tooth 10 front end; land 15 is connected on tooth root 111, is provided with tooth muscle 18 between land 15 and tooth root 111.Land 15, tooth root 111 are positioned on cutter tooth 10 longitudinal axis extension line, and land 15 is cylinders, and land 15 side is gradient along longitudinal axis.The tooth cap 113 that tooth root 111 is greater than groove 110 by a cross section along the ever-reduced cylinder of longitudinal axis, a groove 110 and cross-sectional area is formed; Middle groove 110 matches with snap ring 30; Tooth root 111 matches, by the constraint of cavity 28 with the cavity 28 of toothholder.Tooth muscle 18 is made up of a main body longitudinally triangular in shape and rearwardly projecting bead 19; Bead 19 backward corresponds to the groove 27 forward of toothholder.
The tooth wing 12 is positioned at toothholder 20 front end; The tooth wing 12 is made up of the bead 13 that two transverse directions are relative, and the part that each bead 13 is being connected with the groove 24 of toothholder 20 has fillet.
Toothholder 20 comprises the cavity 28 of nested tooth root 111, the bead mutually nested with snap ring 30 with the interactional groove of cutter tooth.Toothholder 20 is made up of the auxiliary support 21 of a cavity longitudinally run through 28 and attachment shoveling facility, and the structure of cavity 28 forms by along the front groove 27 of axis, middle part closed cavities 28 and rear groove 29.Front groove 27 bilateral symmetry is furnished with two grooves (groove 24 and groove 26), and the line of groove 24 and groove is perpendicular to axis.Rear groove 29 is made up of bottom 21 and sidewall 22, and anterior groove 27 is the open incision along axis.
Snap ring 30 comprises front spring 33 and rear steel plate 31, is provided with rubber 32 between front spring 33 and rear steel plate 31; Front spring 33 and rear steel plate 31 are longitudinally seen in cross section, in I shape with L shape.Front spring 33 and rear steel plate 31 side notched, otch 36 is rounded or oval 36, matches with the annular groove 113 of the tooth root 111 of cutter tooth.Circle or elliptical incision 36 bottom of snap ring 30 are minimum cross section, and global shape is Ω shape.
Details are as follows for the concrete structure of the present embodiment and assembling:
As shown in Figure 1: cutter tooth 10 comprises land 15, the tooth wing 12, tooth muscle 18 and tooth root 111, wherein tooth root 111 is for loading in the cavity 28 of toothholder 20, the cavity 28 of toothholder 20 is designed to be able to the shape holding tooth root 111, and before and after cavity 28, arrange that four or multiple groove (groove about 24, groove 27 and groove 29) are for fixing cutter tooth 10, snap ring 30 directly acts on the groove part on tooth root 111, so, cutter tooth 10 and toothholder 20 are firmly fixed.
As shown in Figure 2: cutter tooth 10 is divided into land 15, the tooth wing 12, tooth muscle 18 and tooth root 111 4 parts.Land 15 is designed to the suitable cutting basil, is symmetrically distributed in longitudinal axis both sides, and namely longitudinal axis is positioned on the plane of symmetry of land 15.Bottom surface and the flank bottom surface of land 15 present certain angle, and object transmits the soil property effect counter-force when dredging effect that longitudinal axis is subject to, and form a triangular structure together with tooth muscle, plays a supporting role.Land 15 is also designed to certain thickness simultaneously, and longitudinally has certain gradient backward.Tooth muscle part is positioned at the top of land 15, and is connected with land 15 is vertical, and the plane of symmetry of the two is identical.Tooth muscle is designed to subtriangular structure, and the rear side of tooth muscle has a bead 19, for the groove of holding at toothholder, plays support and fixation.Furthermore, under the prerequisite ensureing structural strength, cut a part of material at the middle part of tooth muscle for alleviating the weight of tooth, and alleviate a part of cost.The tooth wing 12 is distributed in the both sides of cutter tooth; and have two beads about 13 respectively; for the groove (groove 24 and groove 26) of holding at toothholder 20; play the effect of protection toothholder 20; and the tooth wing 12 is greater than toothholder 20 draw-in groove upper edge surfaces above; namely the tooth wing 12 protects toothholder 20, reduces or avoid the wearing and tearing of toothholder 20.From the side, the tooth wing 12 is substantially triangular in shape structure, and namely Thickness Ratio anterior thickness in the tooth wing 12 rear portion wants large, plays the effect supporting cutter tooth 10.Tooth root 111 is designed to an approximate cylindrical structure, and become an annular groove 110 and one to be similar to the tooth cap 113 of nut structure in the rear design of tooth root 111, cylindrical structure is plugged in toothholder cavity 28, when cutter tooth 10 is subject to percussion, cylinder can reduce this percussion effectively.Annular groove 110 corresponds to the Ω shape side of ring gear device, and by this buckling and locking device, cutter tooth 10 can not depart from toothholder because being subject to pulling force forward or centrifugal force.Similarly, this holding effect needs the participation of nut, therefore must consider this situation during nut designs.
As shown in Figure 3: toothholder 20 is the necessary structures connecting cutter tooth 10 and tool arm.Toothholder 20 design a cavity 28 longitudinally and above three grooves (groove 24, groove 26 and groove 27) of corresponding cutter tooth and one to the after-opening groove 29 corresponding with ring gear.The cavity 28 of toothholder is opening communicating structure forward, and open front is designed to the shape being less than after-opening, plays enough supporting roles when like this cutter tooth being subject to the active force of ground.Similarly, cavity 28 longitudinally the groove 27 in dead ahead and tooth muscle 18 part of cutter tooth 10 corresponding, can provide enough support forces, the groove be symmetrically arranged is corresponding with the flank bead 13 of cutter tooth 10, they play a part equally support cutter tooth 10.The upper limb of groove 24 and lower edge present certain angle, and this angle ensure that the strength impact that cutter tooth 10 is subject to when being subject to complexing action power.The groove at toothholder 20 rear portion is for settling snap ring 30, and this groove design becomes cross-sectional area to be greater than the otch of toothholder cavity 28, and this otch can reduce material weight and reduce cost while guarantee snap ring tooth device 1 sufficient intensity.
As shown in Figure 4: snap ring 30 is used to the necessary parts of locking cutter tooth 10 and toothholder 20.Snap ring 30 is designed to the structure of a kind of similar " sandwich ", and wherein front and back are two-layer is elastic steel sheet, and intermediate layer is elastic caoutchouc 32 structure.Longitudinally see, front and back steel disc presents Ω shape correspondingly, sees from the side, and front steel disc 33 is L shape structures, and rear steel disc 31 is I shape structures, the two structure that substantially takes the shape of the letter U.Cutter tooth 10 be subject to longitudinally pulling force or centrifugal force time, snap ring 30 acts directly on cavity 28 rear portion of toothholder 20, and due to this supporting role, therefore cutter tooth 10 can not depart from toothholder 20.Especially, when cutter tooth 10 to coordinate with toothholder 20 there is allowable error time, the telescopicing performance of elastic caoutchouc provides certain abirritation power.So snap ring 30 firmly can be fixed on cutter tooth 10 on toothholder 20.
