Abstract
The utility model discloses an air-sucking multiple-step hammer-shaped rotary vane used in a multi-functional grinder. The rotary vane is a dumbbell-shaped rotary vane with two wide ends and a narrow middle part, and is respectively provided with a hole on both ends which is loosely matched with a pin; 2-10 tapering steps are arranged from the two ends to the middle; the cross section of the two ends is in the shape of an arc convex surface. The utility model has the advantages that the material beating speed is accelerated because of increased rotary vane steps and increased material beating edges and corners from the two ends of the rotary vane, therefore the material grinding efficiency is greatly improved. The practice shows that the grinding efficiency of the utility model is 70% higher than that of the original double step rotary vane. At the same time, because the cross section of the two ends of the rotary vane is designed in the shape of an arc convex surface, the rotating radius of the rotary vane remain unchanged, thereby the material beating force is strengthened and the effective beating to the material is improved. The rotary vane possesses long replacement cycle and the service life of the complete machine can be prolonged by 75%.
Description
(1) technical field:
The utility model relates to a kind of air draught type pulverizer annex, relates in particular to a kind ofly to be connected air draught type powder machine on the air draught type pulverizer blade impeller with many steps capitate blade.
(2) background technology:
At present, along with the demand that forage volume increases substantially is held by poultry man, also more and more higher to the performance requirement that is used for production of fodder air draught type multipurpose crusher, especially directly affect the many index such as production efficiency, production cost, output of complete machine as the quality of the capitate blade performance that is connected with air draught type pulverizer blade impeller of its main accessories.Thereby the technical staff also constantly makes improvements in production practices and updates; Its first generation product such as ZL93221531.9 disclose " a kind of rotor blade of air draught type multipurpose crusher ", this kind blade is a rectangle, an end is connected by bearing pin on the rotor of pulverizer, the other end is used for impacting pulverized material.The deficiency of this rectangle blade is subjected to the stress point of its bump to have only one less by comminuting matter, and blade is narrow, and blade corner wear in use is fast, and wearing and tearing back blade reduces greatly to the dynamics that impacts of material, and the complete machine crushing effect is reduced.Disclose by improved second generation product of the inventor such as ZL95211840.8 that " " this blade is that two ends are wide, middle narrow to the air draught type multipurpose crusher with double step capitate blade, from two ends to the centre by two steps that diminish between pursuing, have at its two ends and each one in little axle loose fit hole.This blade and rectangle blade blade are relatively, impact point to material increases by three times, but do not satisfy the requirement of producing, simultaneously because this blade two ends section is the plane, along with two section corner angle be impact point wearing and tearing then the radius of turn of blade constantly reduce, cause the shortening of blade length like this, the distance of blade and screen cloth is strengthened, can not effectively impact material, also reduce the impact dynamics of blade more material.
(3) summary of the invention:
The utility model be the impact point of being deposited at double step capitate blade few, revolve and enclose problem that the sheet radius changes along with the wearing and tearing of self and provide a kind of air draught type multipurpose crusher with many steps capitate blade.Its technical scheme of dealing with problems is: a kind of air draught type multipurpose crusher is with many steps capitate blade, it is wide, the middle narrow dumbbell shape blades in two ends, two ends have and each one in the hole of bearing pin loose fit, wherein from two ends to the centre by the 2-10 that diminishes a gradually step, the two ends section is an arc convex surface.
Can also be from two ends to the centre by the 3-10 that diminishes a gradually step.
Good effect of the present utility model is: because the blade step increases, increase the corner angle that impact of material at the blade two ends, thereby the material striking speed increased, be that the material crush efficiency improves greatly, through facts have proved, improve 70% than its crush efficiency of former double step blade, simultaneously, because blade two ends Section Design is an arc convex surface, the radius of turn of blade is remained unchanged, increase material and impact dynamics, and material is effectively impacted the rate raising, the blade replacement cycle is long, and the complete machine long service life can reach 75%.
(4) description of drawings:
Fig. 1 is the structural representation that first generation blade is connected with rotor mill.
Fig. 2 is the structural representation that second generation blade is connected with rotor mill.
Fig. 3 is a structural representation of the present utility model.
(5) specific embodiment.
The utility model is described in further detail below in conjunction with accompanying drawing.
As seen from Figure 3, the utility model is wide, the middle narrow dumbbell shape blades 1 in two ends, and two ends have and each one in the hole of bearing pin 3 loose fit, connect as one by bearing pin 3 and blade impeller 2, from two ends to the centre by three steps that diminish gradually, the two ends section is an arc convex surface.
Claims (2)
1, a kind of air draught type multipurpose crusher is with many steps capitate blade, it is wide, the middle narrow dumbbell shape blades (1) in two ends, two ends have and each one in the hole of bearing pin (3) loose fit, it is characterized in that from two ends that to the centre by the 2-10 that diminishes a gradually step, the two ends section is an arc convex surface.
2, air draught type multipurpose crusher according to claim 1 is with many steps capitate blade, it is characterized in that from two ends to the centre by the 3-10 that diminishes a gradually step.
