[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Reference Figure 1 A vibrating screening device of a crawler mobile crushing station comprises a vibrating screen box 1, a feeding conveyor belt is arranged at the top of the vibrating screen box 1, a screening frame is arranged below the feeding conveyor belt, a discharging conveyor belt is arranged below the screening frame, a plurality of groups of horizontally arranged transverse support rods 3 are arranged in the screening frame, a plurality of groups of vertically arranged vertical support rods 4 are arranged above the transverse support rods 3, a gap is formed between the vertical support rods 4 and the transverse support rods 3 by vertical intersection, a vibrating frame 8 is arranged in the middle position of the screening frame, and the vibrating frame 8 is fixedly connected to the vertical support rods 4.

[0017] In view of the problem that some raw materials in existing mobile crushing stations are directly sent out without being fully crushed, this solution proposes a vibration screening device for crawler mobile crushing stations. Specifically, the raw materials are fed into the screening frame through a feed conveyor belt. The screening frame is supported by a vertical support rod 4 and a horizontal support rod 3. The fully crushed raw materials fall down from the gap between the two, and the raw materials with insufficient crushing and large volume cannot pass through the gap, thereby completing the screening; at the same time, the vibration frame 8 is fixedly connected to the vertical support rod 4, and the vibration frame 8 can make the raw materials that have not fallen down slide down through vibration, and can also shake off the stacked and hidden raw materials, so that the raw materials can be fully screened;

[0018] In this solution, the vertical support rod 4 and the horizontal support rod 3 can be set according to needs. The gap formed between the vertical support rod 4 and the horizontal support rod 3 determines the size of the screened raw materials. Raw materials larger than the gap are screened out, and raw materials smaller than the gap fall and are finally sent out through the discharge conveyor belt.

[0019] Furthermore, the starting end of the feed conveyor belt is connected to the crushing cabin of the crushing station, and a baffle plate 2 is provided at the end of the feed conveyor belt.

[0020] Through this technical solution, the feed conveyor belt feeds the raw materials crushed by the crushing station. The baffle plate 2 prevents the fed raw materials from falling, and at the same time, it also plays a role of buffering and guiding to prevent the raw materials from falling and damaging the screening frame.

[0021] Furthermore, a buffer shaft 6 is arranged directly below the gap, and a buffer plate 7 is arranged at the bottom of the screening frame.

[0022] Through this technical solution, the buffer shaft 6 and the buffer plate 7 are both arranged below the screening frame, just above the discharge conveyor belt. The buffer shaft 6 and the buffer plate 7 are used to buffer the speed reduction to prevent the raw materials from falling directly onto the discharge conveyor belt and damaging the discharge conveyor belt.

[0023] Furthermore, the screening frame is arranged at an inclination, and a return material conveyor belt is arranged at the lower end of the screening frame.

[0024] The screening rack is tilted to facilitate the raw materials that are not fully crushed to slide down from the screening rack. When the raw materials slide into the return conveyor belt, they are sent to the crushing chamber by the return conveyor belt for further crushing until the raw materials meet the delivery requirements.

[0025] Furthermore, a lining plate 5 is provided on the vibration frame 8, and the vibration frame 8 is connected to a vibration motor.

[0026] The lining plate 5 is used to provide support and prevent the raw material from falling from the vibration frame 8.

[0027] Furthermore, the surfaces of the horizontal support rod 3 and the vertical support rod 4 are both smooth structures.

[0028] Through this technical solution, the surfaces of the horizontal support rod 3 and the vertical support rod 4 are both smooth structures, which can facilitate the raw materials that have not passed the screening to slide down, and on the other hand, can prevent the gap between the horizontal support rod 3 and the vertical support rod 4 from getting stuck in the raw materials.

[0029] Working principle: the material is fed into the screening frame through the feed conveyor belt, and the screening frame is supported by the vertical support rod 4 and the horizontal support rod 3. The raw materials that are fully crushed fall down from the gap between the two, and the raw materials that are not fully crushed and have a larger volume cannot pass through the gap, thereby completing the screening; at the same time, the vibration frame 8 is fixedly connected to the vertical support rod 4, and the vibration frame 8 can make the raw materials that have not fallen down slide down through vibration, and the raw materials that slide down are finally sent back to the crushing cabin by the return conveyor belt. At the same time, the vibration frame 8 can also shake off the stacked and hidden raw materials, so that the raw materials are fully screened, ensuring that the delivered raw materials meet the requirements and have better or more effective results.
