Abstract

The utility model relates to a composite sand-making machine which is composed of an upper case (1), a lower box body (2) and a rotor part (3) positioned in the box body and provided with a component body type plate hammer (7), wherein, the inner wall of the upper box body (1) is provided with a reaction frame composed of a group of slope lining boards (8) ranged irregularly; the inner wall of the lower box body (2) is connected with a sieve strip frame (5) on which a row of grate strips. The angle of the reaction frame (4) and the gap of the sieve strip frame can be adjusted by an adjusting part (6). A crushing cavity (10) is arranged between a fly hammer (7) and the sieve strip frame (5). Stone going in from a feed inlet (9) is stricken by the fast rotating plate hammer (7), is thrown to the irregular lining boards (8) on the reaction frame (4) and falls back on the plate hammer (7); through repeated strike, the stone going into the crushing cavity (10) is repeatedly ground into stone sand flowing out the machine. The machine can make stone in high-medium hardness, such as limestone, basalt, etc. into qualified stone sand at one time, and is suitable for high-medium grade engineering constructions, such as traffic, roads, bridges, water conservation, municipal engineering, etc. The utility model has the advantages of small size, small dynamic force, low abrasion, high output, convenient operation and maintenance, low cost, etc.

Description

Combined type system sand machine

Affiliated technical field

The utility model belongs to mechanical field, is specifically related to a kind of combined type system sand machine structure that building stones can be made sandstone.

Background technology

Along with the quickening of China's expressway construction, the stone sand requirement is increasing.Country widelys popularize artificial sand now, at present domesticly generally adopt impact cutting or rod mill with stone system sand, these two kinds of machines generally are earlier that stone is broken for the first time, through screening, to return machine again greater than the stone of 5mm, repeated multiple times just can make stone become stone sand, not only wastes energy, also time-consuming, inefficiency.

Summary of the invention

The purpose of this utility model is: design a kind of combined type system sand machine, it can disposablely make stone sand with stone, and overcoming existing system sand equipment needs the defective of screening repeatedly, increases work efficiency.

Technical solution of the present utility model is: this system sand machine is made of upper box and lower box two parts, rotor portions with one group of split type bar is arranged in the casing, the upper box inwall connects one group of counterattack frame that is the domatic liner plate composition of irregular tooth-like formation, the grating frame that matches with crusher chamber is arranged in lower box, grafting one row's grid section on the grating frame, the adjustment part of profile adjustment counterattack frame and grating frame on the casing.

When the driven by motor armature spindle rotates, stone is entered by charging aperture, by the bar high speed impact on the rotor portions and fragmentation, and it is broken once more to be thrown to counterattack frame portion, bouncing back into bar from irregular counterattack liner plate then continues broken, be crushed to the crusher chamber that certain particle size enters the bar bottom up to stone, crush and grind repeatedly in crusher chamber, qualified sand grains are from the grid section gap outside the discharge machine.

The specific embodiment

This system sand machine is formed by connecting by upper box 1 and lower box 2, rotor portions 3 with one group of split type bar 7 is arranged in the casing, upper box 1 inwall connects one group of counterattack frame 4 that is domatic liner plate 9 compositions of irregular tooth-like formation, upper box 1 is provided with charging aperture 9, grating frame 5 connects on lower box 2 inwalls, be on crusher chamber 10, one row's grid section grafting grating framves 5 between it and the bar 7, adjust and connect one group of adjustment part 6 hitting frame 4 angles and grating frame 5 gaps

On the anti-casing.

Motor drives rotor portions by V belt and is rotated counterclockwise, material is in charging aperture enters broken cavity, after the bar that is subjected to rotating at a high speed on the rotor block hits fragmentation, clash into counterpunch board vertically upward along bar turning circle tangential direction, return vertically downward then, after being clashed into pulverizing mutually, be subjected to bar once more and hit by the material that hit.Through repeatedly repeated stock, fragmentation, fall under gravity in the adjustable crusher chamber, under the extruding repeatedly of bar and grid section, abrasive action, the material more than 90% has been crushed to below the 5mm, discharges from discharge gate.

The utlity model has following advantage:

1, to change the traditional integral formula be split-type structural to bar, the bar overall width is wider than rotor block, thereby it is broken that bar is participated in the rotor block total length, bar participates in fragmentation in the rotor block total length during work, and bar forms sealing together and hits net on rotor, material is not contacted with rotor block, thereby guarantee that rotor block does not does not wear and tear, reduce energy loss during with material impacting, increased breaking capacity, thereby improved the bar life-span;

2, split type bar can outwards be regulated and reverse end for end to use on the rotor block, and the bar utilization rate is brought up to about 65% by 35% of routine, and replacing, easy to maintenance, and counterattack frame counterattack liner plate weares and teares hardly, can adjust arbitrarily with the bar gap;

3, grid section is designed to form plug in construction with the grating frame, can be from last or from inserting down, also can arrange arbitrarily by the discharging-material size size in the grid section gap, all designed adjustable apparatus in the position up and down in grating portion, under the situation that running a period of time wearing and tearing post gap increases, utilize adjusting device, adjust the discharging gap and just can continue to produce.

4, these system sand facility have that volume is little, power is little, abrasion loss is low, output is high, the output of shaking out evenly, convenient operating maintenance, advantage such as cheap.

Claims (4)

1, a kind of combined type system sand machine is characterized in that: it is formed by connecting by upper box (1) and lower box (2), and the rotor portions (3) with one group of split type bar (7) is arranged in its casing.

2, a kind of combined type system sand machine according to claim 1 is characterized in that: upper box (1) inwall connects one group of counterattack frame (4) that is domatic liner plate (8) composition of irregular dentation row example.
