Abstract
The invention discloses an excavator bucket tooth structure, which comprises a tooth seat, a tooth sleeve, a nut, a tooth pin and an iron block, wherein the tooth seat is inserted into the tooth sleeve; a through hole is arranged on the tooth seat; a pin hole corresponds to the through hole and is arranged on the tooth sleeve; the tooth pin penetrates through the pin hole and the through hole, and fixes the tooth seat with the tooth sleeve together under the action of a nut; and the iron block is welded on the pin hole on one side of the tooth sleeve, and is clung to a pin cap of the tooth pin after the tooth pin is inserted into the pin hole so as to fix the tooth pin circumferentially. Compared with the prior art, the excavator bucket tooth structure has the advantages that the strength of bucket teeth is enhanced, abrasion is not easy to occur in operation, and the service life is greatly improved compared with that in the prior art; and the tooth seat is fixed with the tooth sleeve through the tooth pin, so that the detachability is realized, and convenience is provided for operating personnel to replace parts.
Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relate to a kind of bucket tooth structure that is applied to excavator.
Background technology
Excavator bucket teeth is important easy consumption parts on the excavator; By the combined type bucket tooth that toothholder and crown are formed, owing in rugged environment, work for a long time, the crown part in the excavator bucket teeth often is worn; It changes the suitable height of frequency, and corresponding needed cost also is relative increase.
To above-mentioned situation, seem particularly important the application life of how to improve excavator bucket teeth, in Chinese patent " the locking structure of a kind of hydraulic crawler excavator bucket tooth structure "; The patent No. is in 200920164973.3 the patent; Disclose a kind of bucket tooth structure, this bucket tooth is made up of tooth cover, rubber pad, pin pad, toothholder etc., and it is mainly through adding the lastblock General Purpose Rubber in the die cavity that tooth overlaps with toothholder cooperates; Realize preventing the pine rolling of bucket tooth, and then prolong the application life of bucket tooth.But very easily be worn owing to General Purpose Rubber, it also can follow the string receiving under the powerful extruding gradually, the problem of the bucket tooth weak point in application life that causes thereby this patent does not fundamentally solve the rolling of bucket tooth pine.
In addition; With reference to Chinese patent " a kind of excavator bucket toothing "; The patent No. is 200820208863.8, and this bucket tooth structure comprises bucket tooth and the toothholder with pin-and-hole, is connected with jump ring in the inner chamber of toothholder insertion bucket tooth and through pin; Be shaped on counterbore on the pin-and-hole section of said toothholder, described jump ring is positioned at counterbore and is stuck in the jump ring groove on the pin.Though this patent has limited the axially-movable of alligator through pin, its circumferential movement can not prevent, still can aggravate the wearing and tearing of bucket tooth, shortens bucket tooth application life.
Comprehensively above-mentioned, though above-mentioned patent has played certain function at bucket tooth on application life, because bucket tooth is main force-summing element; If just limit the axially-movable of alligator; And circumferential movement is not limited, then still can aggravate the bucket tooth wearing and tearing, shorten its application life.
Summary of the invention
Not enough based on existing in prior technology, main purpose of the present invention is to provide a kind of and improves bucket tooth intensity and prolong the bucket tooth excavator bucket toothing in application life.
To achieve these goals, excavator bucket toothing according to the invention adopts following technical scheme:
Said excavator bucket toothing comprises toothholder, tooth cover, nut and alligator; Said toothholder is for being inserted in the tooth cover; Wherein, On said toothholder, offer a through hole, corresponding with this through hole and put at said tooth and to offer pin-and-hole, said alligator is to pass this pin-and-hole, through hole and under the effect of nut, toothholder and tooth cover are fixed together.
Further, also comprise two iron blocks, this iron block is welded in the pin-and-hole place that tooth overlaps a side.
Further, said tooth cover is the concave structure, and the female parts cross section is rounded.
Further, said toothholder is the raised type structure, and evagination part cross section is rounded.
Further, the screw thread of said nut is a left hand thread.
Further, said pin-and-hole is between this said iron block.
Further, said alligator is the T font, and after alligator inserted pin-and-hole, through hole, its alligator cap was close to and iron block.
Than prior art; Excavator bucket toothing according to the invention both limited the axially-movable of alligator; Also its circumferential movement is limited, in the application life of therefore both having improved alligator, also strengthened the intensity of bucket tooth and made bucket tooth become not easy to wear.
Description of drawings
Fig. 1 is the front section view of excavator bucket toothing according to the invention;
Fig. 2 is the side view of excavator bucket toothing according to the invention;
Fig. 3 is the alligator structure chart in the excavator bucket toothing according to the invention.
The specific embodiment
Come excavator bucket toothing according to the invention is done further to specify below in conjunction with accompanying drawing and specific embodiment.
With reference to shown in Figure 1, excavator bucket toothing according to the invention has detachable and advantages such as job stabilization, long service life, and it mainly comprises toothholder 10, tooth cover 11, alligator 12, nut 13 and iron block 14.
In the present invention, said toothholder 10 is the raised type structure, and it is inserted in the tooth cover 11; Corresponding with toothholder 10; This tooth cover 11 is the concave structure, just agrees with it when toothholder 10 is inserted to when tooth overlaps 11 female parts, again; For the ease of framework and the assembling of toothholder 10 with tooth cover 11, the cross section of the evagination part of toothholder 10 and the female parts of tooth cover 11 all is set to circle.
In addition, on said toothholder 10, offer a through hole (not shown), corresponding with this through hole and on said tooth cover 11, offer pin-and-hole 110.Said alligator 12 is for passing pin-and-hole 110, through hole, and is tightened against tooth through nut 13 and puts, and toothholder 10 is fixed in the tooth cover 11.
Said iron block 14 overlaps 11 1 side pin-and-holes, 110 places for being welded in tooth, and in the present invention, said iron block 14 quantity are 2; When being welded; Two iron blocks 14 for be welded on place, limit, pin-and-hole 110 hole and between distance just consistent with the width of the pin cap 121 of alligator 12, behind alligator 12 insertion pin-and-holes 110, these two iron blocks 14 just are close to the pin cap 121 of alligator 12; Thereby alligator 12 has been played circumferential fixation, further limited the circumferential movement of alligator 12.
In addition; Loosening in order to guarantee that said nut 13 is difficult for when the excavator long working, in the present invention, the screw thread of said nut 13 is for adopting left hand thread; Therefore when excavator is worked; Though have external force to act on the nut 13,, the situation of nut loosening can not take place under this external force effect because employing is that left hand thread can tighten on the contrary automatically.
Further, because the present invention fixes toothholder 10, tooth cover 11 for adopting parts such as alligator 12, nut 13, therefore; The present invention has detachability, and when said toothholder 10 serious wear, operating personnel can take out alligator 12 through unclamping nut 13; And then toothholder 10 taken out from tooth cover 11 change; Certainly, also can change in the time of need changing for other structure of the present invention, repeat no more at this according to above-mentioned steps.
The above is merely the preferred embodiments of the present invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes manual of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
