Example a kind of existing pulverizer as shown in Figure 1 can be used to pulverize the fertilizer that easily lump such as calcium superphosphate.This pulverizer comprises housing 1, power transmission shaft 2, power transmission shaft belt pulley 3, motor 4, motor pulley 5 and is contained in charging aperture 6 on the housing 1, is opened in the discharging opening 7 of housing 1 bottom.The coaxial power transmission shaft belt pulley 3 that is equipped with of power transmission shaft 2 one ends wherein, the other end stretches into housing 1 inside and end is connected with at least two pulverizing chains 8.The middle part of power transmission shaft 2 is installed on the end face center of housing 1 by bearing 9.Motor 4 is positioned on the outer surface of housing 1 side, and its output shaft is coaxially connected with motor pulley 5.Power transmission shaft belt pulley 3 is connected with motor pulley that the two connects by belt, and then motor 4 starts and will drive two belt pulleys, then drives power transmission shaft 2 and rotates, and final the drive pulverized chain 8 rotations, to break caking fertilizer into pieces.
The defective of this pulverizer is, owing to adopt the belt pulley transmission, and power transmission shaft belt pulley 3, motor pulley 5 and motor 4 output shafts consist of the triangle transmission, rotary speed unstabilization is fixed, in case charging is arranged inhomogeneous or the big or small inequality of block, it is large or resistance is unbalanced to pulverize the suffered resistance of chain 8, causes easily belt creep, affects crush efficiency.
Summary of the invention
In order to overcome defects, the utility model provides a kind of transmission to stablize, prevent transmission slip, the pulverizer that power attenuation is little.
A kind of pulverizer of the present utility model, comprise housing, power transmission shaft, motor, concavo-convex shaft coupling, pulverize chain, bearing block, described enclosure interior is provided with division board, the upper space and the lower space that described enclosure interior are divided into mutual separation, described power transmission shaft vertically is installed on the described division board by bearing block, the upper end of described power transmission shaft is stretched into described upper space and is connected with the output shaft of described motor by concavo-convex shaft coupling, motor mounting is on the housing top wall outer surface of upper space, the lower end of described power transmission shaft stretches into described lower space and the lower end is connected with at least two pulverizing chains, also has the clean-up port on the housing sidewall of lower space.
In pulverizer described in the utility model, described bearing block comprises upper and lower two bearings, and upper bearing (metal) is deep groove ball bearing, and lower bearing is single-row angular contact ball bearing.
In pulverizer described in the utility model, described concavo-convex shaft coupling comprises two flange flanges that arrange in opposite directions, and the contact-making surface of described two flange flanges is all uneven, is provided with the abrasive rubber pad between two rough contact-making surfaces.
In pulverizer described in the utility model, the lower end of described power transmission shaft is equipped with ring flange, and described pulverizing chain is contained on the edge of described ring flange and is symmetrical.
Adopt pulverizer of the present utility model, has following beneficial effect: because power transmission shaft directly is connected with motor output shaft is coaxial, and the connection of concavo-convex shaft coupling is firm, transmission of torque efficient is high, can not produce belt creep cause can't transmission problem, greatly simplify simultaneously the structure of existing pulverizer, simplified transmission link, can reduce the energy loss of each link; The design of division board can also prevent that the dust of pulverizing from entering into concavo-convex shaft coupling and motor, reduced wearing and tearing.
Description of drawings
Fig. 1 is the structural representation of the pulverizer of prior art.
Fig. 2 is the schematic diagram of the pulverizer of the utility model preferred embodiment.
The specific embodiment
The utility model relates to a kind of pulverizer, has reliable transmission stability, and its structure comprises housing 10, power transmission shaft 20, motor 40, concavo-convex shaft coupling 35, pulverizes chain 80, bearing block 90 as shown in Figure 2.
Wherein, housing 10 in echelon, housing 10 inside are provided with division board 11, and housing 10 inside are divided into upper and lower two spaces of mutually separating, and are respectively upper space S1 and lower space S2.Motor 40 is contained on the top wall outer surface of housing 10, and its output shaft stretches into the upper space S1 in the housing 10, and is connected with power transmission shaft 20 upper ends by concavo-convex shaft coupling 35.Concavo-convex shaft coupling 35 comprises two flange flanges that arrange in opposite directions; flange flange and motor 40 output shaft fixed connections; another flange flange and power transmission shaft 20 upper ends are connected; the contact-making surface of two flange flanges is all uneven; between two rough contact-making surfaces, be provided with the abrasive rubber pad, can prevent the brinelling when contact-making surface is shut down because of the pulverizer start.
Upper space S1 and concavo-convex 35 coaxial connections of shaft coupling are stretched in the upper end of power transmission shaft 20, the lower end stretches into lower space S2 and terminal surface fixedly is equipped with two ring flanges 50, the edge of ring flange 50 has four holes equidistantly, and the aperture position of upper and lower two ring flanges 50 is corresponding one by one, one connecting line passes respectively two corresponding holes and is connected with one pulverizes chain 80, it is symmetrical along ring flange 50 edges then to have four pulverizing chains 80, is used for smashing block.
