more reports to screen use Use a descending sleeve block to resist the actuator, which is installed on the inner plate of the screen box: one set of electric vibration is preferably installed on the upper support of the screen box, and the micro vibrator is used. Two special vibrators are installed on the two sides of the screen box. Small specifications of the two micro motors can be used to make the vibration force smaller by adjusting the angle of the vibration. 7.2 Screen surface and its fastening pipe
7.2.1 In order to meet the needs of large-scale and large-scale material screening and coal and stone separation, the heavy-duty vibrating screen needs to have a larger cross-sectional area and impact resistance. The trapezoidal cross-section is used as the screen bar. In order to reduce noise and improve the shock rate, it can also be used. Open. Rubber strip: Use grid to fix the surface bracket [:: see Figure 2, 1 side rejection: 2 stripping surface: 3 screen surface bracket: 4U child paste: 5--roll Figure 2

7.2.2 Circular moving screen and compound moving screen can be connected with stainless steel plate, screen plate, composite plate, etc. The case is that the middle pool is controlled at a depth of less than 900mm, the middle fixed screen is 21mm old, the middle part should be fixed with screw control, and the screen can be tensioned with a pressure regulator, see Figure. Figure 4
7.2.3 The surface of the linear moving screen The lower layer of the single-layer screen and double-layer screen adopts a stainless steel screen with a super frame: the upper layer of the double-layer screen adopts a white support when the penetration does not exceed 15m, and a perforated screen plate or a woven screen when it exceeds 15m. The tightening method is to use a press and a wood plate to tighten the two plates, see Figure 5, and use a bolt to tighten the fastener between the fasteners, see Figure 6. Figure

The crossbeam used for the screen is a closed profile with flanges at both ends. At present, most of them are circular shapes, short shapes, and can also be welded. The shape can be formed by hot or cold, but in the long direction, it can only be formed once. Welding must be fully welded and annealed. The vibration range will be arranged in the direction of vibration. [: The side plate and rear baffle of the screen are disassembled. The discharge nozzle and the horizontal direction are connected by high-strength bolts or ring drags. The parts with less force can also be connected by ordinary screws and locking bolts:
7.4 Transmission device
Two types of rotational connection transmission are used. 7.4.1 Direct-actuation
The motor drives the actuator directly through the coupling, see Figure 9. There are three types of couplings, which can be selected as needed in the design. 1 Motor: 2 Direct coupling: 3 Actuator: 4 Vibrator: Figure 9

) Intermediate coupling: This coupling is a replacement part of the left car, see Figure 2. This coupling can also be used to connect two vibrators: Figure 10
3) Tire coupling: It has an inner flange and a whole piece of tape, see Figure 11. Because the rigidity of the base is large, it can transmit large moments. The diameter of the center of the body is small, and it can be subjected to the deformation of the longitudinal runout. The F motor and the vibrator can be connected. Its shaft length is small, which can reduce the width of the vibrating screen. The rubber coupling (a kind of coupling) is composed of flanges, reduced parts, plates and probes. Because the shaft length of this coupling is small, it can be used to connect two vibrators. 7.4.2 Non-direct transmission The motor has passed through the V fast transmission, and the energy is connected through the coupling, see Figure 13.
