The specific embodiment
Referring to figs. 1 through Figure 19, comprise tooth and adaptor assembly 11 according to the invention of first embodiment of the invention, this tooth and adaptor assembly are used for excavator or similar machine.This assembly 11 comprises adapter 21, and this adapter has first end 23 that is suitable for receiving tooth 41, and locking mechanism 71 is received in first end so that tooth 41 is locked with respect to adapter 21.
Fig. 9 shows adapter 21 to Figure 14.This adapter 21 has second end 25, and this second end is suitable for being fixed to scraper bowl or the like that excavates on the machine (not shown).The structure of second end 25 changes according to its concrete application.
Each sidewall 35 comprises first passage 37 and second channel 39, first passage 37 from front surface 29 backward along nose 27 longitudinal extensions, second channel 39 at the upper surface 31 of nose 27 to extending between the soffit 33, thereby with first passage 37 separated into two parts and vertical with first passage basically.
The part of second channel 39 above first passage 37 comprises slope 40 and the part 41 wideer than the lower part of second channel 39, and this slope 40 is adjacent with first passage 37, as in Figure 10 and Figure 13, showing best, and below will explanation reasons.
Fig. 1 has illustrated tooth 41 in Fig. 8.Tooth 41 is suitable for being received on the nose 27 of adapter 21, thereby is fixed to adapter 21 releasedly.Tooth 41 comprises slot 43, and this slot is limited by opening 45, rear surface 47, upper wall 49, diapire 51 and two sidewalls 53.The surface complementarity of the shape of slot 43 and nose 27, thus be slidingly matched (snug fit) when being received on the adapter 21, tooth 41 is provided.
Each sidewall 53 comprises third channel 55.Third channel 55 is parallel with opening 45 basically, thereby when assembling, the second channel 39 of nose 27 and the third channel 55 common encapsulation 91 that limit.
Each sidewall 53 also is provided with inwardly outstanding elongate protrusion 59, and this elongate protrusion is suitable for being slidably received between the erecting stage of tooth 41 and adapter 21 in the first passage 37 of adapter nose 27.Elongate protrusion 59 is extended between the rear surface 47 of third channel 55 and slot 43, and vertical with third channel 55 basically.
The inner surface of each sidewall 53 also is provided with protuberance 61, and this protuberance protrudes in the opening 45 and with elongate protrusion 59 and vertically aligns.As Fig. 7 and Fig. 8 best shown in, elongate protrusion 59 and protuberance 61 by third channel 55 separately, and protuberance 61 and third channel 55 phase deviations.
With reference to Figure 15, locking mechanism 71 comprises two pin 73 (only showing one), and the hole 57a that each pin is suitable for the upper wall 49 by tooth 41 between erecting stage is received in the encapsulation 91.
Each pin 73 comprises the metal retaining clip 75 that projection 77 is provided.Retaining clip 75 is bonded to the elastic flexible material 79 such as polyurethane.
Elastic flexible material 79 is received in the recess 81 of metal shell 83.
When rigging pilotage 73, when pin 73 is in its normal condition, projection 77 is extended the border that surmounts housing 83.
In use, adapter 21 is fixed on the parts such as the excavating equipment of unshowned scraper bowl.Adapter 21 is soldered to scraper bowl usually.Be not subjected to great wearing and tearing by tooth 41 protection adapters 21, tooth 41 can be changed when being worn or damage.Because wearing and tearing or damage are very normal, so importantly tooth 41 can remove from adapter 21 easily and promptly.
To Figure 19, when tooth 41 was assembled to adapter 21, the slot 43 of tooth 41 received the nose 27 of adapters 21 with reference to Figure 16, thus protuberance 61 and elongate protrusion 59 align with the first passage 37 of nose 27, and be slidably received in wherein.Tooth 41 continues to slide along nose 27, engages with the upper surface 31 and the soffit 33 of nose 27 respectively up to the inner surface of the upper wall 49 of slot 43 and the inner surface of diapire 51, aligns so that encapsulation 91 to be provided with second channel 39 at this position third channel 55.
Because protuberance 61 and third channel 55 skews, therefore when tooth 41 was received on the adapter 21, the part of first passage 37 provided the recess 93 between second channel 39 and protuberance 61, below with detailed explanation reasons.
