Description

Hammer mill is put the sand device automatically

Technical field

The utility model relates to hammer mill, relates in particular to a kind of hammer mill and puts the sand device automatically.

Background technology

Hammer mill is also claimed sand shaker, is a kind of of pulverizer, and main working parts is the rotor that has tup.Rotor is made up of main shaft, disk, bearing pin and hammer.The motor drives rotor is rotation at a high speed in crusher chamber.Material inlet feeds in the machine material from top, receives the strike, impact, shearing, abrasive action of the hammer of high-speed motion and pulverizes.In the rotor bottom, be provided with in sieve plate, the comminuting matter less than the grade of screen size and discharge through sieve plate, on sieve plate, continue to receive the strike and the grinding of hammer greater than the coarse fraction detention of screen size, at last through outside the sieve plate discharge machine.The situation of suffocation usually appears in the prior art hammer mill when using, material gets lodged on the sieve plate not get off, and increases running resistance, and at last by forced-stopping machine, manual work is drawn clearly, wastes time and energy.Existing hammer mill obviously has defective and exists, and remain to be improved on reality is used.Thus, the improving of the above-mentioned defective of the utility model inventor thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.

Summary of the invention

The purpose of the utility model is in order to overcome the defective of prior art, to provide simple in structure, practical, have

A kind of hammer mill of imitating is put the sand device automatically, usually occurs the suffocation problem when hammer mill uses to solve.

To achieve these goals, the technical scheme of the utility model is following:

A kind of hammer mill is put the sand device automatically, comprises sieve plate, support, and sieve plate is in support; It is characterized in that said sieve plate has fixed screen deck and active sieve plate, the active sieve plate bottom leans on the support both sides respectively to be connected with a gripper shoe, and two gripper shoes, one end has a fixed axis to pass through couplet mutually; The gripper shoe other end and first active plate are hinged, under active sieve plate, also have a back shaft, and back shaft is through support; Support sleeve is connected to second active plate, and first active plate and second active plate, the 3rd active plate are hinged, and the 3rd active plate is hinged with the 4th active plate again; The 4th active plate and interior fixed connecting plate are hinged, also have a switch shaft, and switch shaft is parallel with back shaft through support; Fixed connecting plate is fixed on the switch shaft in said, outside support, is equipped with motor, and motor drives clasp nut through gear drive; Clasp nut is built-in with screw mandrel; One end of screw mandrel is movably hinged with outer fixed connecting plate, and outer fixed connecting plate is fixed on the switch shaft, and said outer affixed connecting plate both sides are equipped with limit switch.

Motor send; Motor is through gear driven clasp nut and screw mandrel, and screw mandrel swings outer fixed connecting plate, and then switch shaft is rotated; Switch shaft drives interior fixed connecting plate again; Interior fixed connecting plate advance and retreat push-and-pull the 4th active plate, the 3rd active plate, second active plate and first active plate make active sieve plate open or close, the outer affixed connecting plate stroke of limit switch control and the switching-over of outer affixed connecting plate both sides.

The situation of suffocation when hammer mill uses, occurs, rotor speed is slack-off, and the motor of the utility model obtains the slack-off signal of rotating speed and promptly starts work.

The utility model is the bottom of hammer mill, and rotor is with the lower part.

The equipment that the utlity model has is simple, and is safe and reliable, and efficient is high, solved when hammer mill uses a suffocation difficult problem usually to occur, and good economic benefits is arranged.

The utility model is applicable to hammer mill.
