The specific embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of shoveling facility comprise the cutter tooth 10, toothholder 20 and the snap ring 30 that are attached on the shoveling facility with snap ring tooth device; Dismountable cutter tooth 10 passes through snap ring 30 holdings on toothholder 20; cutter tooth 10 comprises the tooth wing 12 of the land 15 of dredging soil property, the tooth root 111 that supports usefulness, protection toothholder and the tooth muscle of strengthening 18; land 15 is positioned at cutter tooth 10 front ends; land 15 is connected on the tooth root 111, and 111 on land 15 and tooth root are provided with tooth muscle 18.Land 15, tooth root 111 are positioned on cutter tooth 10 longitudinal axis extension lines, and land 15 is cylinders, and land 15 sides are gradient along longitudinal axis.Tooth root 111 is made of along the ever-reduced cylinder of longitudinal axis, groove 110 and cross-sectional area tooth cap 113 greater than groove 110 cross section; Middle groove 110 is complementary with snap ring 30; Tooth root 111 is complementary with the cavity 28 of toothholder, is subjected to the constraint of cavity 28.Tooth muscle 18 is formed along longitudinal axis main body and rearwardly projecting bead 19 triangular in shape by one; Bead 19 backward is corresponding to the groove forward 27 of toothholder.
The tooth wing 12 is positioned at toothholder 20 front ends; The tooth wing 12 is made up of two horizontal relative beads 13, and each bead 13 has fillet in the part that is connected with the groove 24 of toothholder 20.
Details are as follows for the concrete structure of 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 the cavity 28 of the toothholder 20 of packing into, the cavity 28 of toothholder 20 is designed to be able to hold the shape of tooth root 111, and arrange that in cavity 28 front and back four or a plurality of groove (groove about 24, groove 27 and groove 29) are used for fixedly cutter tooth 10, snap ring 30 directly acts on the groove part on the tooth root 111, so, cutter tooth 10 is firmly fixing with toothholder 20.
As shown in Figure 2: cutter tooth 10 is divided into land 15, the tooth wing 12, tooth muscle 18 and 111 4 parts of tooth root.Land 15 is designed to the suitable cutting basil, and bilateral symmetry is distributed in the longitudinal axis both sides, and namely longitudinal axis is positioned on the plane of symmetry of land 15.The bottom surface of land 15 and flank bottom surface present certain angle, purpose be transmit be subjected on the longitudinal axis make the soil property effect counter-force of time spent in dredging, and constitute a triangular structure with the tooth muscle, play a supporting role.Land 15 also is designed to certain thickness simultaneously, and has certain gradient backward along longitudinal axis.The tooth muscle partly is positioned at the top of land 15, and with 15 vertical connections of land, the plane of symmetry of the two is identical.The tooth muscle is designed to subtriangular structure, and the rear side of tooth muscle has a bead 19, is used for holding at the groove of toothholder, plays and supports and fixation.Furthermore, under the prerequisite that guarantees structural strength, cut a part of material at the middle part of tooth muscle and be used 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; be used for holding at the groove (groove 24 and groove 26) of toothholder 20; play the effect of protection toothholder 20; and the tooth wing 12 is top greater than toothholder 20 draw-in groove upper edge surfaces; be that toothholder 20 is lived in 12 protections of the tooth wing, reduce or avoid the wearing and tearing of toothholder 20.From the side, the tooth wing 12 is substantially triangular in shape structure, and namely the tooth wing 12 rear portion thickness are bigger than anterior thickness, plays the effect of supporting cutter tooth 10.Tooth root 111 is designed to an approximate cylindrical structure, and become an annular groove 110 and a tooth cap 113 that is similar to nut structure in the rear design of tooth root 111, cylindrical structure is plugged in the toothholder cavity 28, when cutter tooth 10 was subjected to percussion, cylinder can reduce this percussion effectively.Annular groove 110 is corresponding to the Ω shape side of ring gear device, and by this buckling and locking device, cutter tooth 10 can not break away from toothholder because of pulling force or the centrifugal force that is subjected to forward.Similarly, this holding effect needs the participation of nut, so must consider this situation during nut designs.
As shown in Figure 3: toothholder 20 is the necessary structures that connect cutter tooth 10 and tool arm.One of toothholder 20 design along three grooves (groove 24, groove 26 and groove 27) of the corresponding cutter tooth of cavity 28 and front of longitudinal axis and one to after-opening and ring gear corresponding groove 29.The cavity 28 of toothholder is opening communicating structure forward, and open front is designed to the shape less than after-opening, plays enough supporting roles when like this cutter tooth being subjected to the active force of ground.Similarly, cavity 28 is corresponding with tooth muscle 18 parts of cutter tooth 10 along the groove 27 in longitudinal axis dead ahead, and enough support forces can be provided, and the groove that is symmetrically arranged is corresponding with the flank bead 13 of cutter tooth 10, and they play a part to support cutter tooth 10 equally.The upper limb of groove 24 and lower edge present certain angle, and this angle has guaranteed cutter tooth 10 when being subjected to complexing action power and the strength impact that is subjected to.The groove at toothholder 20 rear portions is used for settling snap ring 30, and this groove design becomes cross-sectional area greater than the otch of toothholder cavity 28, and this otch can reduce material weight and reduce cost when guarantee snap ring tooth device 1 sufficient intensity.
As shown in Figure 4: snap ring 30 is 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 ", wherein before and after the two-layer elastic steel sheet that is, the intermediate layer is elastic caoutchouc 32 structures.See that along longitudinal axis the front and back steel disc presents the Ω shape correspondingly, see that preceding steel disc 33 is L shaped structures on from the side, back steel disc 31 is I shape structures, the two structure that takes the shape of the letter U substantially.When cutter tooth 10 was subjected to along longitudinal axis pulling force or centrifugal force, snap ring 30 acted directly on cavity 28 rear portions of toothholder 20, because this supporting role, therefore cutter tooth 10 can not break away from toothholder 20.Especially, when cutter tooth 10 cooperates with toothholder 20 when allowable error occurring, the telescopicing performance of elastic caoutchouc provides certain abirritation power.So snap ring 30 can firmly be fixed on cutter tooth 10 on the toothholder 20.
