Abstract
The utility model relates to the technical field of hydraulic knapper assemblies, in particular to a novel knapping assembly of a hydraulic knapper. The knapping assembly comprises a drill rod, a front sleeve, a rear sleeve and a machine head, wherein the front sleeve and the rear sleeve are sequentially connected with the drill rod in a sleeved mode. The machine head is fixedly connected with the drill rod through two flat pins and fixing grooves in the two sides of the drill rod, two first positioning pins are vertically connected with the machine head and the two flat pins in a penetrating insert mode respectively, two second positioning pins are arranged below the two flat pins and fixedly connected with grooves in the two sides of the front sleeve, an oil filling port with a grease fitting is formed in the middle of the machine head, and an air leakage hole with an air leakage valve and an air leakage valve element is formed in the upper portion of the machine head. By the adoption of the structure, the structure between the drill rod and the machine head is compact, connection between the drill rod and the machine head is reliable, the loosening phenomenon is prevented from occurring after long-time operation, therefore, reliability and usability of the knapper are improved, knapping efficiency is high, and noise is low.
Description
Technical field
The utility model relates to hydraulic burster component technology field, is specifically related to the broken assembly of novel hydraulic destroyer.
Background technology
The hydraulic breaking hammer power resources of using in engineering at present are in excavator, loader or pumping plant, drive operating principle that full hydraulic, liquid gas association type etc. are arranged, be all to promote drill rod by piston movement, make drill rod produce impact force action on rock, rely on impact force to make rock rupture.But that the shortcoming of this destroyer is efficiency is low, noise large, impact force reaction meeting to excavator produce damage, and can not the larger rock of fragmentation volume.In addition, it is unreliable between the head of existing destroyer and drill steel, to be connected, and after long working, there will be head and drill steel to become flexible phenomenon, thereby has reduced reliability and the functional performance of destroyer.
Summary of the invention
The purpose of this utility model is to provide the broken assembly of a kind of compact conformation, the novel hydraulic destroyer that safe and reliable, efficiency is high, noise is little, breaking capacity is strong.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: the broken assembly of novel hydraulic destroyer, comprise drill steel, successively with the protheca of described drill steel socket, rear cover and head, described head is fixedly connected with described drill steel with the holddown groove of drill steel both sides by two cotter pilotages, two the first alignment pins respectively with described head, two cotter pilotages vertically intert and connect, the below of described two cotter pilotages is provided with two the second alignment pins, described two the second alignment pins are fixedly connected with the groove of described protheca both sides, the middle part of described head is provided with the tank filler sleeve with grease nipple, the top of described head is provided with the bleeder port with gas bleeder valve and disappointing spool.
Further, the end of described the first alignment pin is provided with the first pin plug.
Further, the end of described the second alignment pin is provided with the second pin plug.
Further, be provided with successively back-up ring and O type circle between the bleeder port of described disappointing spool and head.
The utlity model has following beneficial effect: the broken assembly of novel hydraulic destroyer described in the utility model, mainly comprise drill steel, protheca, rear cover and head, wherein, head is fixedly connected with drill steel by two cotter pilotages, in addition, be respectively equipped with tank filler sleeve and bleeder port on middle part and the top of head; The utility model adopts said structure to make compact conformation between drill steel and head, is connected reliably, avoid occurring after long working becoming flexible phenomenon, thereby improved reliability and the functional performance of destroyer, and crushing efficiency is high, noise is low.In addition, the utlity model has reasonable in design, the characteristics such as Stability Analysis of Structures firm, low cost of manufacture.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, the broken assembly of novel hydraulic destroyer, comprise drill steel 1, successively with the protheca 2 of described drill steel 1 socket, rear cover 3 and head 4, described head 4 is fixedly connected with described drill steel 1 with the holddown groove 1-1 of drill steel 1 both sides by two cotter pilotages 5, two the first alignment pins 6 respectively with described head 4, two vertical interting of cotter pilotage 5 connect, the below of described two cotter pilotages 5 is provided with two the second alignment pins 7, described two the second alignment pins 7 are fixedly connected with the groove 2-1 of described protheca 2 both sides, in the present embodiment, design like this, make the compact conformation between head and drill steel, connect more firmly reliable, not there will be loosening phenomenon after long working yet, the middle part of described head 4 is provided with the tank filler sleeve 4-1 with grease nipple 8, the effect of tank filler sleeve is can directly refuel by its hole, the top of described head 4 is provided with the bleeder port 4-2 with gas bleeder valve 9 and disappointing spool 10, but the effect of bleeder port is by its hole emission gases.
The end of described the first alignment pin 6 is provided with the first pin plug 11, and the end of described the second alignment pin 7 is provided with the second pin plug 12, and wherein, the first pin plug and the second pin plug all can effectively prevent that dust, impurity etc. from entering in head.
Be provided with successively back-up ring 13 and O type circle 14 between the bleeder port 4-2 of described disappointing spool 10 and head 4, the effect of back-up ring and O type circle is to make disappointing spool to be connected compacter and sealing with bleeder port, avoids impurity to invade.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
