Description
Technical field
The utility model relates to the hammer crusher in the grain feed industry, particularly a kind of quick-replaceable hammer slice.
Background technology
Horizontal hammer crusher is widely used in the disintegrating process of the particulate materials such as all feeds factory, Alcohol Plant, lemon factory, food factory, grease factory.The fixed form of most of horizontal hammer crusher hammer leaf as shown in Figure 1 at present, comprise the some hammer frame plates that axially are set up in parallel along pulverizer main shaft, hammer frame plate circumferentially is evenly equipped with some installing holes, installing hole corresponding to described each hammer frame plate along main shaft axially coaxial relatively and run through the bearing pin that suit is used for installing hammer frame plate, on the bearing pin successively spacer sleeve spacer and hammer leaf are housed.The hammer leaf of this structure installs and fixes mode, when being installed, hammer leaf spacer and hammer leaf successively order cover to be installed on the bearing pin, each bearing pin is set with one group of hammer leaf and spacer passes a hammer frame plate installing hole again, until bearing pin is run through all hammer frame plates, then with the bearing pin two ends by the split pin axial restraint, finish one group of hammer leaf and install.A hammer crusher circumferentially has some groups of bearing pins and hammer leaf along hammer frame plate.Change hammer leaf also needs spacer, hammer leaf are removed from hammer frame plate in the lump together with bearing pin at every turn, and then spacer and new hammer leaf are installed again successively.
Because hammer leaf is the consumable accessory of pulverizer, change more frequent.Each hammer leaf of changing need to consume the long time.And hammer crusher respectively to organize the hammer leaf arrangement mode different, if operate unskilledly, be easy to the hammer leaf wrongly installed is caused doing over again, moreover the gap of hammer leaf and spacer is less, and the operating space is not enough during installation, is not easy to install very much, according to statistics, when changing hammer leaf, the time loss more than 60% is being installed on the spacer.
Micromill hammer leaf and spacer quantity amount to tens, change two about 1 hour times of skilled workers' needs an of hammer leaf; Large-scale hammer mills and spacer quantity have four or five hundred, even more, and two skilled workers change a cover hammer leaf often needs several hours.Medium-scale above enterprise, often needs to stop production half a day and just can finish when changing hammer leaf all take large-scale pulverizer as main, seriously delays manufacturing schedule.Therefore, in the urgent need to designing a kind of Stability Analysis of Structures, reliable, easy and simple to handle, can shorten again hammer leaf and change the time, simplify hammer leaf and change program.
The utility model content
The utility model provides a kind of quick-replaceable hammer slice for the needs of prior art, is intended to
Do not need the repeated disassembled and assembled spacer when making hammer crusher change hammer leaf, obviously save the time of changing hammer leaf, and Stability Analysis of Structures, reliable, reasonable in design.
The purpose of this utility model is to realize like this, a kind of quick-replaceable hammer slice, comprise the some hammer frame plates that axially are set up in parallel along pulverizer main shaft, described hammer frame plate circumferentially is evenly equipped with some installing holes, the installing hole that described each hammer frame plate is corresponding is axially coaxial relative along main shaft, described installing hole is that screwed hole and screw thread are fixed with spacer, described spacer periphery is provided with the male end that is connected with the hammer frame plate screwed hole, along running through the bearing pin that is arranged with for the suit hammer leaf in axial each the coaxial spacer of main shaft, described hammer leaf is disposed on the bearing pin by spacer.
Adopt structure of the present utility model, when hammer leaf is installed, first the spacer screw thread is fixedly attached in the screwed hole of each hammer frame plate, then will is set with one by one hammer leaf on the bearing pin and penetrates in spacer corresponding to each hammer frame plate, the more solid two ends of bearing pin axial restraint is finished the installation of one group of hammer leaf; When needs are changed hammer leaf, only need to pull down one by one hammer leaf from each spacer hole extraction bearing pin and get final product, do not need to dismantle spacer, when again hammer leaf being installed, only need on bearing pin, to be set with one by one hammer leaf and to penetrate in the corresponding spacer of each hammer frame plate, and then the axial restraint bearing pin.This process of changing hammer leaf has been omitted the disassembly process of spacer, has saved the time of most of replacing hammer leaf, and simultaneously, spacer maintains static at hammer frame plate, and the mistake of when also having avoided the replacing hammer leaf hammer leaf arrangement mode being arranged causes unnecessary doing over again.Therefore adopt hammer leaf of the present utility model to change structure, obviously save the time of changing hammer leaf, simplify the replacing program, and reasonable in design, all kinds of large, medium and small hammer crusher structures adapted to especially.
For ease of the fixed installation of spacer, the spacer other end corresponding with the spacer male end is provided with is convenient to the square of tool holder or hexagon pinching end.
Fixing for ease of bearing pin and is provided with the ring washer groove in the spacer hole of bearing pin two ends socket, and described bearing pin is by being arranged on the hole elastic scheibe axial restraint in the ring washer groove.
