Description

Straw crusher
Technical field
The utility model relates to a kind of disintegrating machine that is exclusively used in stalk.
Background technology
According to statistics by the end of the year in 2004, biomass power generation installations such as whole world employing stalk have reached 3,900 ten thousand kilowatts, alternative 7,000 ten thousand tons of standard coals, straw power generation is faced with Three Difficult Issues at present: the one, and the volume to weight ratio of stalk is little, the weight of unit volume is little, and these have caused the inconvenience of straw collecting and transportation; The 2nd, stalk is elongated and more pliable and tougher, when the boiler internal combustion, be difficult to feeding, and it is insufficient to burn, optimal way is that stalk is carried out effective break process, its granularity is reached in the 3-5cm scope, and there is not proper large-scale straw crusher now, in industry, all adopt straw kneading and cutting machine general on original aquaculture, what tool was represented meaning in this type of kneading and cutting machine will count China Agricultural University's development, the patent No. is: the stalk of ZL97249011 is rubbed and is cut mixer, comprise hopper, casing, main grinding rotor, the stationary knife group, belt pulley and motor, wherein main grinding rotor comprises the rotating shaft that is arranged in the casing, be installed in several in the rotating shaft moving knife, the stationary knife group hingedly is installed on the sidewall of casing, and pulls to the operating room with spring; During work, material enters back middle the passing of stationary knife group that certain interval is arranged from moving knife and two of high speed rotating from material, in this process, both be subjected to the shearing of moving knife to material, material is rubbed in the gap between moving knife and stationary knife again, and throw to operating room's inwall by the rotor of high speed rotating, dragging row by rotor subsequently rubs again, to improve broken joint rate to stalk joint crust, be convenient to animal digesting and assimilating to feed, but the biomass fuel generating is to broken joint rate no requirement (NR), material time of staying in the process of rubbing is long, the power consumption height, and disposal ability is less; Mainly material is sheared simultaneously, in crushing process, had the possibility of leaking material, can't guarantee the uniformity of pulverizing by moving knife.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, the straw crusher that a kind of material is short by the time in crushing process, power consumption is low, disposal ability is big is provided, in crushing process, stop simultaneously the leak possibility of material, guarantee the uniformity of pulverizing.
For achieving the above object, straw crusher of the present utility model, comprise hopper, casing, main grinding rotor, two or more secondary grinding rotors, array belt pulley and a motor, it is characterized in that described casing comprises that pulverizing the storehouse has the feed bin that of discharge gate with it, pulverizes the storehouse and comprises Yi Zhucang, two or more secondary storehouses that link to each other with main storehouse; Main grinding rotor is arranged in the main storehouse, comprise rotating shaft longitudinally, be installed in several in the rotating shaft driving knife, be provided with secondary grinding rotor in each secondary storehouse, comprise rotating shaft longitudinally, be installed in the auxilliary moving knife of several handles in the rotating shaft, driving knife and auxilliary moving knife are staggered; Each rotating shaft links with one group of belt pulley and motor respectively, and impeller also is installed in the rotating shaft in going out feed bin;
Operation principle of the present utility model is: main grinding rotor and each secondary grinding rotor are done rotation in opposite directions by motor-driven separately, drive main and auxiliary moving knife and form enclosed shearing ring structure; When stalk passes through the gap of the main and auxiliary moving knife of high speed rotating, directly repeatedly sheared by main and auxiliary moving knife, there is not the process of rubbing, the swabbing action that adds impeller in the top discharge storehouse, material falls rapidly in pulverizing the cabin, fully guarantees its discharging speed, thereby reaches the purpose that material is short by the time, power consumption is low, disposal ability is big, stop the leakage material phenomenon in the crushing process again, guarantee the uniformity of pulverizing;
As further improvement of the utility model, in the rotating shaft of the driving knife that is higher than the top, also be provided with one group of tup, be used for knocking fragmentation, with the protection blade to entering the hard material (brick, stone etc.) of pulverizing the storehouse;
As further improvement of the utility model, on the madial wall in main storehouse, be provided with tooth plate; Partial material is thrown to the sidewall in main storehouse by grinding rotor, can increase the chance that this partial material is broken;
As further improvement of the utility model, on the lateral wall in main storehouse, be provided with access door, easy to maintenance;
In sum, the utility model has shortened material passing through the time in crushing process, has the advantage that power consumption is low, disposal ability is big, stops the leak possibility of material simultaneously, guarantees the uniformity pulverized, and is easy to maintenance.

Embodiment
By illustrated in figures 1 and 2, the straw crusher of the utility model embodiment, comprise hopper 1, casing 2, main grinding rotor 3, three secondary grinding rotors 4, four groups of belt pulleys and motors 5, described casing 2 comprise pulverize that storehouse 6 and its have a discharge gate go out feed bin 7, pulverize storehouse 6 and comprise a main storehouse 8, three also uniform secondary storehouses 9 that link to each other with main storehouse 8; Main grinding rotor 3 is arranged in the main storehouse 8, comprise rotating shaft longitudinally 10, be installed in several in the rotating shaft 10 driving knife 11 and one group of tup 12, the position of tup 12 is higher than the driving knife of the top, on the madial wall in main storehouse 8, be provided with tooth plate 13, in each secondary storehouse 9, be provided with secondary grinding rotor 4, comprise rotating shaft longitudinally 14, be installed in the auxilliary moving knife 15 of several handles in the rotating shaft 14, driving knife 11 is staggered with auxilliary moving knife 15; Each rotating shaft 10,14 links with one group of belt pulley and motor 5 respectively, by shown in Figure 3, in the rotating shaft 10 in going out feed bin 7 impeller 16 is installed also, by shown in Figure 4, is provided with access door 17 on the lateral wall in main storehouse 8;
