Table 1 main design parameters and equipment state
Now to adopt mode as shown in Figure 1 that material in the chassis hopper is carried out discharge operation as example, sprocket-type unloader of the present utility model is made related description.
A) main design parameters and equipment state determines
The material shapes of discharging object has less graininess, larger bulk, and size differs greatly and is in mutual admixture between the difform material.Therefore, when selecting sprocket wheel and conveyer chain specification, the Carrier chain link distance should be greater than the lump material diameter.Simultaneously, owing to being mixed with little grainy material, sprocket-type scraper lifting machine scraper plate shape should adopt the slice shape of sheet steel cutting; reduce material particles slip phenomenon when promoting slide assemblies and move with this; reduce surplus material quantity, guarantee the discharging rate, and improve discharging efficient.
According to chassis hopper width and definite sprocket wheel and conveyer chain specification, adopt two cover gigs to make up the (see figure 10) that is staggered, the interior pattern that three gigs are used in combination of every cover gig combination.
After adopting above-mentioned gig array configuration, as after using water conservancy diversion chute substitution level slat conveyer to reach hoisting depth as material it being delivered to the outer equipment of equipment stand, the relation that then promotes between slide assemblies ramp length dimension C and the hoisting depth should meet the relation shown in Figure 11 and formula (1) or the formula (2).
C=D/sinA………………………………（1）
C=（E+FtgB）/sinA……………………（2）
In the formula:
A---inclination angle, slide assemblies ramp is generally 30 °;
B---inclination angle, water conservancy diversion chute ramp, span are 〉=45 °;
C---slide assemblies ramp length;
D---slide assemblies minimum lift height;
E---the hopper degree of depth;
F---water conservancy diversion chute minimum level fed distance (identical with the slide assemblies width).
Can be determined by above-mentioned relation, when slide assemblies minimum lift height D and water conservancy diversion chute minimum level fed distance F increase, slide assemblies ramp length C all increases.And in order to reach the purpose that material is flowed in the water conservancy diversion chute, inclination angle, water conservancy diversion chute ramp must more than or equal to 45 °, can not reduce.If adopt the grader leveling blade conveyer then do not have similar restriction, when hoisting depth D was reduced 50%, slide assemblies ramp length C also can reduce 50%, and sprocket-type scraper lifting machine and slide assemblies size all can significantly reduce.Simultaneously, the supporting construction size of mount fixing structure and actuating device also can significantly reduce.Therefore, should adopt the conduct of grader leveling blade conveyer with the equipment of mass transport to equipment stand.
According to the state that adopts the grader leveling blade conveyer, slide assemblies minimum lift height D satisfies the surrounding structure space constraints and gets final product.After it is determined, can determine all the other relative dimensions of sprocket-type unloader.
B) sprocket-type unloader operation sheet
As shown in figure 10, in the time of before the trolley array that is loaded with material arrives the wheeled unloader of the first chain of stations, the combination of first set gig starts running.Material is after meeting the requirements of hoisting depth along supporting plate slideway upward movement under the scraper plate effect, fall in the grader leveling blade conveyer, material is horizontal motion under the effect of grader leveling blade conveyer inside strake, leaves equipment stand and arrives assigned address, finishes the discharging work of half side material in the hopper.Trolley array continues to travel and arrives the wheeled unloader of second chain of stations, and the second cover gig combination starts running, finishes the discharging work of the half side material of residue in the hopper according to said process.
