Abstract
The invention discloses a rapping device for a grading screen, belonging to the technical field of grading treatment for particles and powder. The device is formed by that an impact pendulum support, an impact pendulum bearing cross beam and an impact cross rod are fixed on a screen body; and an impact pendulum is hinged on the impact pendulum bearing cross beam and capable of swinging around the impact pendulum bearing cross beam. Simultaneously, the device is provided with a drive wheel, a drive shaft, a drive arm, an impact shaft and an impact shaft sleeve; power and motion are transferred to the impact shaft sleeve by a motor, and an adjustment plate on the impact pendulum is pushed by the impact shaft sleeve, so that the impact pendulum swings and rotates by an angle; and in the case that the impact shaft sleeve leaves from the adjustment plate, the cross rod is impacted by the impact pendulum during resetting, so that a screen surface fixed on the screen body generates vibration, thus improving a screening effect. The device is formed with a U-shaped groove and provided with a cross rod adjustment seat on the impact pendulum; and the swinging amplitude of the impact pendulum can be adjusted by changing and adjusting the position relationship between the cross rod and the cross rod adjustment seat. Via the rapping device, the phenomenon of the high failure rate caused by the high vibration frequency of a vibration motor and electromagnetic vibration is avoided.
Description
Technical field
The present invention belongs to rapping classification field, is mainly used in the unemployed gradation technology such as cement, chemical industry, metallurgy, grain, feed.
Background technology
The existing multiplex vibrating motor of classifying screen rapping apparatus, electromagnetic vibrator or utilize the displacement of classifying equipoment to realize the rapping campaign.The rapping of above-mentioned several rapping apparatus has many-sided unconformable place, the one, rapping equipment is that the rapping frequency is higher, easily cause damage or the fault rate of equipment high, the 2nd, utilize classifying equipoment self rotatablely move to realize rapping, the rapping frequency is by the rotary speed restriction of classification self, then also can't use this rapping method to non-rotary classifying screen.
Summary of the invention
The objective of the invention is to have the rapping apparatus that an a kind of material grader that is suitable for flexibly is provided.
Technical scheme of the present invention is: rotate by the motor drives driving wheel, driving wheel passes to driving shaft with power with rotatablely moving, the other end at driving shaft is provided with actuating arm, be provided with the strike axle in the end of actuating arm and hit shaft sleeve, rotatablely moving passes to the strike axle and hits sleeve by actuating arm with rotary power.Classifying screen in circumference branch is provided with a plurality of strike pendulum by circle distribution, lay out in strike and to be mounted with adjustable plate, adjustable plate along the circumferential direction has certain lift, can promote adjustable plate when hitting shaft sleeve when along the circumferential direction rotation is through adjustable plate under actuating arm drives, make and hit pendulum around hitting angle of the hinged rotary oscillation of pendulum, when the strike sleeve leaves adjustable plate, hitting pendulum recovery swing and strike is hitting on the cross bar, hit cross bar and be on the sieve nest that is fixed on fixing compass screen surface, the strike cross bar can make compass screen surface be subject to rapping and produce certain vibration.In order to regulate easily the position relationship that hits between pendulum and the strike axle sleeve, this invention is laid out in strike and is provided with U-lag and cross bar adjustment seat, be consolidated with the adjusting montant and regulate cross bar at adjustable plate, adjustable plate and the relative position that hits pendulum and strike shaft sleeve can be regulated by adjusting nut, the pendulum angle that hits pendulum can be changed with this.
Description of drawings
The present invention will be described below in conjunction with accompanying drawing:
Fig. 1: a kind of rapping apparatus structural representation of classifying screen;
Fig. 2: a kind of rapping apparatus structural representation top view of classifying screen
Fig. 3: a kind of rapping apparatus structural representation partial enlarged drawing I of classifying screen
Fig. 4: a kind of rapping apparatus structural representation partial enlarged drawing II of classifying screen
Among the figure: 1-driving wheel, 2-driving shaft, 3-actuating arm, 4-hits axle, and 5-hits shaft sleeve, 6-cross bar adjustment seat, the 7-adjusting nut, 8-regulates cross bar, and 9-regulates montant, the 10-adjustable plate, it is hinged that 11-hits pendulum, and 12-hits cross bar, 13-hits pendulum, and 14-hits swinging rack, 15-compass screen surface, 16-hits pendulum bearing cross beam, 17-U shape groove.
The specific embodiment
As depicted in figs. 1 and 2, driving wheel, driving shaft, actuating arm and strike axle, strike sleeve can be bearing on the fixing body by bearing, compass screen surface and strike pendulum are by circle distribution, actuating arm can hit a plurality of strike pendulum in rotary course, hitting pendulum is fixed on the sieve by hitting swinging rack, same strike cross bar also is to be fixed on the sieve nest, when hitting shimmy strike cross bar, can make sieve nest produce vibration, also just drive simultaneously the vibration of compass screen surface, motion, the raising grading effect of compass screen surface material can be realized accelerating, compass screen surface obstruction etc. can be prevented simultaneously.
This invention technology can realize by frame for movement fully.
Claims (2)
1. the rapping apparatus of a classifying screen, it is characterized in that: by driving wheel power is passed to the strike shaft sleeve with rotatablely moving by driving shaft, actuating arm and strike axle, promotion is installed in to hit lays out the adjustable plate that certain lift is arranged along hitting on the sleeve direction of rotation, make and hit pendulum around hitting angle of the hinged rotary oscillation of pendulum, when the strike sleeve leaves adjustable plate, hit pendulum and recover to swing and also hit the strike cross bar that is fixed on the sieve nest, make compass screen surface be subject to certain rapping and produce certain vibration.
2. the rapping apparatus of a kind of classifying screen according to claim 1, lay out in strike and to be provided with U-lag and cross bar adjustment seat, be consolidated with the adjusting montant and regulate cross bar at adjustable plate, adjustable plate and the relative position that hits pendulum and strike shaft sleeve can be regulated by adjusting nut, the pendulum angle that hits pendulum can be changed with this.
